5,793 | Cumulative distribution function | In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable X {\displaystyle X} , or just distribution function of X {\displaystyle X} , evaluated at x {\displaystyle x} , is the probability that X {\displaystyle X} will take a value less than or equal to x {\displaystyle x} .
Every probability distribution supported on the real numbers, discrete or "mixed" as well as continuous, is uniquely identified by a right-continuous monotone increasing function (a càdlàg function) F : R → [ 0 , 1 ] {\displaystyle F\colon \mathbb {R} \rightarrow [0,1]} satisfying lim x → − ∞ F ( x ) = 0 {\displaystyle \lim _{x\rightarrow -\infty }F(x)=0} and lim x → ∞ F ( x ) = 1 {\displaystyle \lim _{x\rightarrow \infty }F(x)=1} .
In the case of a scalar continuous distribution, it gives the area under the probability density function from minus infinity to x {\displaystyle x} . Cumulative distribution functions are also used to specify the distribution of multivariate random variables.
The cumulative distribution function of a real-valued random variable X {\displaystyle X} is the function given by
where the right-hand side represents the probability that the random variable X {\displaystyle X} takes on a value less than or equal to x {\displaystyle x} .
The probability that X {\displaystyle X} lies in the semi-closed interval ( a , b ] {\displaystyle (a,b]} , where a < b {\displaystyle a<b} , is therefore
In the definition above, the "less than or equal to" sign, "≤", is a convention, not a universally used one (e.g. Hungarian literature uses "<"), but the distinction is important for discrete distributions. The proper use of tables of the binomial and Poisson distributions depends upon this convention. Moreover, important formulas like Paul Lévy's inversion formula for the characteristic function also rely on the "less than or equal" formulation.
If treating several random variables X , Y , … {\displaystyle X,Y,\ldots } etc. the corresponding letters are used as subscripts while, if treating only one, the subscript is usually omitted. It is conventional to use a capital F {\displaystyle F} for a cumulative distribution function, in contrast to the lower-case f {\displaystyle f} used for probability density functions and probability mass functions. This applies when discussing general distributions: some specific distributions have their own conventional notation, for example the normal distribution uses Φ {\displaystyle \Phi } and ϕ {\displaystyle \phi } instead of F {\displaystyle F} and f {\displaystyle f} , respectively.
The probability density function of a continuous random variable can be determined from the cumulative distribution function by differentiating using the Fundamental Theorem of Calculus; i.e. given F ( x ) {\displaystyle F(x)} ,
as long as the derivative exists.
The CDF of a continuous random variable X {\displaystyle X} can be expressed as the integral of its probability density function f X {\displaystyle f_{X}} as follows:
In the case of a random variable X {\displaystyle X} which has distribution having a discrete component at a value b {\displaystyle b} ,
If F X {\displaystyle F_{X}} is continuous at b {\displaystyle b} , this equals zero and there is no discrete component at b {\displaystyle b} .
Every cumulative distribution function F X {\displaystyle F_{X}} is non-decreasing and right-continuous, which makes it a càdlàg function. Furthermore,
Every function with these four properties is a CDF, i.e., for every such function, a random variable can be defined such that the function is the cumulative distribution function of that random variable.
If X {\displaystyle X} is a purely discrete random variable, then it attains values x 1 , x 2 , … {\displaystyle x_{1},x_{2},\ldots } with probability p i = p ( x i ) {\displaystyle p_{i}=p(x_{i})} , and the CDF of X {\displaystyle X} will be discontinuous at the points x i {\displaystyle x_{i}} :
If the CDF F X {\displaystyle F_{X}} of a real valued random variable X {\displaystyle X} is continuous, then X {\displaystyle X} is a continuous random variable; if furthermore F X {\displaystyle F_{X}} is absolutely continuous, then there exists a Lebesgue-integrable function f X ( x ) {\displaystyle f_{X}(x)} such that
for all real numbers a {\displaystyle a} and b {\displaystyle b} . The function f X {\displaystyle f_{X}} is equal to the derivative of F X {\displaystyle F_{X}} almost everywhere, and it is called the probability density function of the distribution of X {\displaystyle X} .
If X {\displaystyle X} has finite L1-norm, that is, the expectation of | X | {\displaystyle |X|} is finite, then the expectation is given by the Riemann–Stieltjes integral
and for any x ≥ 0 {\displaystyle x\geq 0} ,
as shown in the diagram. In particular, we have
As an example, suppose X {\displaystyle X} is uniformly distributed on the unit interval [ 0 , 1 ] {\displaystyle [0,1]} .
Then the CDF of X {\displaystyle X} is given by
Suppose instead that X {\displaystyle X} takes only the discrete values 0 and 1, with equal probability.
Then the CDF of X {\displaystyle X} is given by
Suppose X {\displaystyle X} is exponential distributed. Then the CDF of X {\displaystyle X} is given by
Here λ > 0 is the parameter of the distribution, often called the rate parameter.
Suppose X {\displaystyle X} is normal distributed. Then the CDF of X {\displaystyle X} is given by
Here the parameter μ {\displaystyle \mu } is the mean or expectation of the distribution; and σ {\displaystyle \sigma } is its standard deviation.
A table of the CDF of the standard normal distribution is often used in statistical applications, where it is named the standard normal table, the unit normal table, or the Z table.
Suppose X {\displaystyle X} is binomial distributed. Then the CDF of X {\displaystyle X} is given by
Here p {\displaystyle p} is the probability of success and the function denotes the discrete probability distribution of the number of successes in a sequence of n {\displaystyle n} independent experiments, and ⌊ k ⌋ {\displaystyle \lfloor k\rfloor } is the "floor" under k {\displaystyle k} , i.e. the greatest integer less than or equal to k {\displaystyle k} .
Sometimes, it is useful to study the opposite question and ask how often the random variable is above a particular level. This is called the complementary cumulative distribution function (ccdf) or simply the tail distribution or exceedance, and is defined as
This has applications in statistical hypothesis testing, for example, because the one-sided p-value is the probability of observing a test statistic at least as extreme as the one observed. Thus, provided that the test statistic, T, has a continuous distribution, the one-sided p-value is simply given by the ccdf: for an observed value t {\displaystyle t} of the test statistic
In survival analysis, F ¯ X ( x ) {\displaystyle {\bar {F}}_{X}(x)} is called the survival function and denoted S ( x ) {\displaystyle S(x)} , while the term reliability function is common in engineering.
While the plot of a cumulative distribution F {\displaystyle F} often has an S-like shape, an alternative illustration is the folded cumulative distribution or mountain plot, which folds the top half of the graph over, that is
where 1 { A } {\displaystyle 1_{\{A\}}} denotes the indicator function and the second summand is the survivor function, thus using two scales, one for the upslope and another for the downslope. This form of illustration emphasises the median, dispersion (specifically, the mean absolute deviation from the median) and skewness of the distribution or of the empirical results.
If the CDF F is strictly increasing and continuous then F − 1 ( p ) , p ∈ [ 0 , 1 ] , {\displaystyle F^{-1}(p),p\in [0,1],} is the unique real number x {\displaystyle x} such that F ( x ) = p {\displaystyle F(x)=p} . This defines the inverse distribution function or quantile function.
Some distributions do not have a unique inverse (for example if f X ( x ) = 0 {\displaystyle f_{X}(x)=0} for all a < x < b {\displaystyle a<x<b} , causing F X {\displaystyle F_{X}} to be constant). In this case, one may use the generalized inverse distribution function, which is defined as
Some useful properties of the inverse cdf (which are also preserved in the definition of the generalized inverse distribution function) are:
The inverse of the cdf can be used to translate results obtained for the uniform distribution to other distributions.
The empirical distribution function is an estimate of the cumulative distribution function that generated the points in the sample. It converges with probability 1 to that underlying distribution. A number of results exist to quantify the rate of convergence of the empirical distribution function to the underlying cumulative distribution function.
When dealing simultaneously with more than one random variable the joint cumulative distribution function can also be defined. For example, for a pair of random variables X , Y {\displaystyle X,Y} , the joint CDF F X Y {\displaystyle F_{XY}} is given by
where the right-hand side represents the probability that the random variable X {\displaystyle X} takes on a value less than or equal to x {\displaystyle x} and that Y {\displaystyle Y} takes on a value less than or equal to y {\displaystyle y} .
Example of joint cumulative distribution function:
For two continuous variables X and Y:
For two discrete random variables, it is beneficial to generate a table of probabilities and address the cumulative probability for each potential range of X and Y, and here is the example:
given the joint probability mass function in tabular form, determine the joint cumulative distribution function.
Solution: using the given table of probabilities for each potential range of X and Y, the joint cumulative distribution function may be constructed in tabular form:
For N {\displaystyle N} random variables X 1 , … , X N {\displaystyle X_{1},\ldots ,X_{N}} , the joint CDF F X 1 , … , X N {\displaystyle F_{X_{1},\ldots ,X_{N}}} is given by
Interpreting the N {\displaystyle N} random variables as a random vector X = ( X 1 , … , X N ) T {\displaystyle \mathbf {X} =(X_{1},\ldots ,X_{N})^{T}} yields a shorter notation:
Every multivariate CDF is:
Not every function satisfying the above four properties is a multivariate CDF, unlike in the single dimension case. For example, let F ( x , y ) = 0 {\displaystyle F(x,y)=0} for x < 0 {\displaystyle x<0} or x + y < 1 {\displaystyle x+y<1} or y < 0 {\displaystyle y<0} and let F ( x , y ) = 1 {\displaystyle F(x,y)=1} otherwise. It is easy to see that the above conditions are met, and yet F {\displaystyle F} is not a CDF since if it was, then P ( 1 3 < X ≤ 1 , 1 3 < Y ≤ 1 ) = − 1 {\textstyle \operatorname {P} \left({\frac {1}{3}}<X\leq 1,{\frac {1}{3}}<Y\leq 1\right)=-1} as explained below.
The probability that a point belongs to a hyperrectangle is analogous to the 1-dimensional case:
The generalization of the cumulative distribution function from real to complex random variables is not obvious because expressions of the form P ( Z ≤ 1 + 2 i ) {\displaystyle P(Z\leq 1+2i)} make no sense. However expressions of the form P ( ℜ ( Z ) ≤ 1 , ℑ ( Z ) ≤ 3 ) {\displaystyle P(\Re {(Z)}\leq 1,\Im {(Z)}\leq 3)} make sense. Therefore, we define the cumulative distribution of a complex random variables via the joint distribution of their real and imaginary parts:
Generalization of Eq.4 yields
as definition for the CDS of a complex random vector Z = ( Z 1 , … , Z N ) T {\displaystyle \mathbf {Z} =(Z_{1},\ldots ,Z_{N})^{T}} .
The concept of the cumulative distribution function makes an explicit appearance in statistical analysis in two (similar) ways. Cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value. The empirical distribution function is a formal direct estimate of the cumulative distribution function for which simple statistical properties can be derived and which can form the basis of various statistical hypothesis tests. Such tests can assess whether there is evidence against a sample of data having arisen from a given distribution, or evidence against two samples of data having arisen from the same (unknown) population distribution.
The Kolmogorov–Smirnov test is based on cumulative distribution functions and can be used to test to see whether two empirical distributions are different or whether an empirical distribution is different from an ideal distribution. The closely related Kuiper's test is useful if the domain of the distribution is cyclic as in day of the week. For instance Kuiper's test might be used to see if the number of tornadoes varies during the year or if sales of a product vary by day of the week or day of the month. | [

] | In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable X , or just distribution function of X , evaluated at x , is the probability that X will take a value less than or equal to x . Every probability distribution supported on the real numbers, discrete or "mixed" as well as continuous, is uniquely identified by a right-continuous monotone increasing function F : R → [ 0 , 1 ] satisfying lim x → − ∞ F = 0 and lim x → ∞ F = 1 . In the case of a scalar continuous distribution, it gives the area under the probability density function from minus infinity to x . Cumulative distribution functions are also used to specify the distribution of multivariate random variables. | 2001-03-24T16:08:42Z | 2023-11-10T18:40:29Z | [

5,794 | Central tendency | In statistics, a central tendency (or measure of central tendency) is a central or typical value for a probability distribution.
Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s.
The most common measures of central tendency are the arithmetic mean, the median, and the mode. A middle tendency can be calculated for either a finite set of values or for a theoretical distribution, such as the normal distribution. Occasionally authors use central tendency to denote "the tendency of quantitative data to cluster around some central value."
The central tendency of a distribution is typically contrasted with its dispersion or variability; dispersion and central tendency are the often characterized properties of distributions. Analysis may judge whether data has a strong or a weak central tendency based on its dispersion.
The following may be applied to one-dimensional data. Depending on the circumstances, it may be appropriate to transform the data before calculating a central tendency. Examples are squaring the values or taking logarithms. Whether a transformation is appropriate and what it should be, depend heavily on the data being analyzed.
Any of the above may be applied to each dimension of multi-dimensional data, but the results may not be invariant to rotations of the multi-dimensional space.
Several measures of central tendency can be characterized as solving a variational problem, in the sense of the calculus of variations, namely minimizing variation from the center. That is, given a measure of statistical dispersion, one asks for a measure of central tendency that minimizes variation: such that variation from the center is minimal among all choices of center. In a quip, "dispersion precedes location". These measures are initially defined in one dimension, but can be generalized to multiple dimensions. This center may or may not be unique. In the sense of L spaces, the correspondence is:
The associated functions are called p-norms: respectively 0-"norm", 1-norm, 2-norm, and ∞-norm. The function corresponding to the L space is not a norm, and is thus often referred to in quotes: 0-"norm".
In equations, for a given (finite) data set X, thought of as a vector x = (x1,…,xn), the dispersion about a point c is the "distance" from x to the constant vector c = (c,…,c) in the p-norm (normalized by the number of points n):
For p = 0 and p = ∞ these functions are defined by taking limits, respectively as p → 0 and p → ∞. For p = 0 the limiting values are 0 = 0 and a = 0 or a ≠ 0, so the difference becomes simply equality, so the 0-norm counts the number of unequal points. For p = ∞ the largest number dominates, and thus the ∞-norm is the maximum difference.
The mean (L center) and midrange (L center) are unique (when they exist), while the median (L center) and mode (L center) are not in general unique. This can be understood in terms of convexity of the associated functions (coercive functions).
The 2-norm and ∞-norm are strictly convex, and thus (by convex optimization) the minimizer is unique (if it exists), and exists for bounded distributions. Thus standard deviation about the mean is lower than standard deviation about any other point, and the maximum deviation about the midrange is lower than the maximum deviation about any other point.
The 1-norm is not strictly convex, whereas strict convexity is needed to ensure uniqueness of the minimizer. Correspondingly, the median (in this sense of minimizing) is not in general unique, and in fact any point between the two central points of a discrete distribution minimizes average absolute deviation.
The 0-"norm" is not convex (hence not a norm). Correspondingly, the mode is not unique – for example, in a uniform distribution any point is the mode.
Instead of a single central point, one can ask for multiple points such that the variation from these points is minimized. This leads to cluster analysis, where each point in the data set is clustered with the nearest "center". Most commonly, using the 2-norm generalizes the mean to k-means clustering, while using the 1-norm generalizes the (geometric) median to k-medians clustering. Using the 0-norm simply generalizes the mode (most common value) to using the k most common values as centers.
Unlike the single-center statistics, this multi-center clustering cannot in general be computed in a closed-form expression, and instead must be computed or approximated by an iterative method; one general approach is expectation–maximization algorithms.
The notion of a "center" as minimizing variation can be generalized in information geometry as a distribution that minimizes divergence (a generalized distance) from a data set. The most common case is maximum likelihood estimation, where the maximum likelihood estimate (MLE) maximizes likelihood (minimizes expected surprisal), which can be interpreted geometrically by using entropy to measure variation: the MLE minimizes cross-entropy (equivalently, relative entropy, Kullback–Leibler divergence).
A simple example of this is for the center of nominal data: instead of using the mode (the only single-valued "center"), one often uses the empirical measure (the frequency distribution divided by the sample size) as a "center". For example, given binary data, say heads or tails, if a data set consists of 2 heads and 1 tails, then the mode is "heads", but the empirical measure is 2/3 heads, 1/3 tails, which minimizes the cross-entropy (total surprisal) from the data set. This perspective is also used in regression analysis, where least squares finds the solution that minimizes the distances from it, and analogously in logistic regression, a maximum likelihood estimate minimizes the surprisal (information distance).
For unimodal distributions the following bounds are known and are sharp:
where μ is the mean, ν is the median, θ is the mode, and σ is the standard deviation.

5,796 | Celebrity | Celebrity is a condition of fame and broad public recognition of a person or group as a result of the attention given to them by mass media. An individual may attain a celebrity status from having great wealth, their participation in sports or the entertainment industry, their position as a political figure, or even from their connection to another celebrity. 'Celebrity' usually implies a favorable public image, as opposed to the neutrals 'famous' or 'notable', or the negatives 'infamous' and 'notorious'.
In his 2020 book Dead Famous: an unexpected history of celebrity, British historian Greg Jenner uses the definition:
Celebrity (noun): a unique persona made widely known to the public via media coverage, and whose life is publicly consumed as dramatic entertainment, and whose commercial brand is made profitable for those who exploit their popularity, and perhaps also for themselves.
Although his book is subtitled "from Bronze Age to Silver Screen", and despite the fact that "Until very recently, sociologists argued that celebrity was invented just over 100 years ago, in the flickering glimmer of early Hollywood" and the suggestion that some medieval saints might qualify, Jenner asserts that the earliest celebrities lived in the early 1700s, his first example being Henry Sacheverell.
Athletes in Ancient Greece were welcomed home as heroes, had songs and poems written in their honor, and received free food and gifts from those seeking celebrity endorsement. Ancient Rome similarly lauded actors and notorious gladiators, and Julius Caesar appeared on a coin in his own lifetime (a departure from the usual depiction of battles and divine lineage).
In the early 12th century, Thomas Becket became famous following his murder. He was promoted by the Christian Church as a martyr and images of him and scenes from his life became widespread in just a few years. In a pattern often repeated, what started as an explosion of popularity (often referred to with the suffix 'mania') turned into long-lasting fame: pilgrimages to Canterbury Cathedral where he was killed became instantly fashionable and the fascination with his life and death have inspired plays and films.
The cult of personality (particularly in the west) can be traced back to the Romantics in the 18th century, whose livelihood as artists and poets depended on the currency of their reputation. The establishment of cultural hot-spots became an important factor in the process of generating fame: for example, London and Paris in the 18th and 19th centuries. Newspapers started including gossip columns and certain clubs and events became places to be seen in order to receive publicity. David Lodge called Charles Dickens the "first writer … to feel the intense pressure of being simultaneously an artist and an object of unrelenting public interest and adulation", and Juliet John backed up the claim for Dickens "to be called the first self-made global media star of the age of mass culture."
Theatrical actors were often celebrities. Restaurants near theaters, where actors would congregate, began putting up caricatures or photographs of actors on celebrity walls in the late 19th century. The subject of widespread public and media interest, Lillie Langtry made her West End theatre debut in 1881 causing a sensation in London by becoming the first socialite to appear on stage. The following year she became the poster-girl for Pears Soap, becoming the first celebrity to endorse a commercial product. In 1895, poet and playwright Oscar Wilde became the subject of "one of the first celebrity trials".
The movie industry spread around the globe in the first half of the 20th century and now, the familiar concept of the instantly recognizable faces of its superstars. Yet, celebrity was not always tied to actors in films, especially when cinema was starting as a medium. As Paul McDonald states in The Star System: Hollywood's Production of Popular Identities, "in the first decade of the twentieth century, American film production companies withheld the names of film performers, despite requests from audiences, fearing that public recognition would drive performers to demand higher salaries." Public fascination went well beyond the on-screen exploits of movie stars and their private lives became headline news: for example, in Hollywood the marriages of Elizabeth Taylor and in Bollywood the affairs of Raj Kapoor in the 1950s. Like theatrical actors before them, movie actors were the subjects of celebrity walls in restaurants they frequented, near movie studios, most notably at Sardi's in Hollywood.
The second half of the century saw television and popular music bring new forms of celebrity, such as the rock star and the pop group, epitomised by Elvis Presley and the Beatles, respectively. John Lennon's highly controversial 1966 quote: "We're more popular than Jesus now," which he later insisted was not a boast, and that he was not in any way comparing himself with Christ, gives an insight into both the adulation and notoriety that fame can bring. Unlike movies, television created celebrities who were not primarily actors; for example, presenters, talk show hosts, and newsreaders. However, most of these are only famous within the regions reached by their particular broadcaster, and only a few such as Oprah Winfrey, Jerry Springer, or David Frost could be said to have broken through into wider stardom. Television also gave exposure to sportspeople, notably Pelé after his emergence at the 1958 FIFA World Cup, with Barney Ronay in The Guardian stating, "What is certain is that Pelé invented this game, the idea of individual global sporting superstardom, and in a way that is unrepeatable now."
In the '60s and early '70s, the book publishing industry began to persuade major celebrities to put their names on autobiographies and other titles in a genre called celebrity publishing. In most cases, the book was not written by the celebrity but by a ghostwriter, but the celebrity would then be available for a book tour and appearances on talk shows.
Forbes magazine releases an annual Forbes Celebrity 100 list of the highest-paid celebrities in the world. The total earnings for all top celebrity 100 earners totaled $4.5 billion in 2010 alone.
For instance, Forbes ranked media mogul and talk show host, Oprah Winfrey as the top earner "Forbes magazine's annual ranking of the most powerful celebrities", with earnings of $290 million in the past year. Forbes cites that Lady Gaga reportedly earned over $90 million in 2010. In 2011, golfer Tiger Woods was one of highest-earning celebrity athletes, with an income of $74 million and is consistently ranked one of the highest-paid athletes in the world. In 2013, Madonna was ranked as the fifth most powerful and the highest-earning celebrity of the year with earnings of $125 million. She has consistently been among the most powerful and highest-earning celebrities in the world, occupying the third place in Forbes Celebrity 100 2009 with $110 million of earnings, and getting the tenth place in the 2011 edition of the list with annual earnings equal to $58 million. Beyoncé has also appeared in the top ten in 2008, 2009, 2010, 2013, 2017, and topped the list in 2014 with earnings of $115 million. Cristiano Ronaldo followed by Lionel Messi in 2020 became the first two athletes in a team sport to surpass $1 billion in earnings during their careers.
Forbes also lists the top-earning dead celebrities, with singer Michael Jackson, fantasy author J. R. R. Tolkien and children's author Roald Dahl each topping the annual list with earnings of $500 million over the course of a year.
Celebrity endorsements have proven very successful around the world where, due to increasing consumerism, a person owns a status symbol by purchasing a celebrity-endorsed product. Although it has become commonplace for celebrities to place their name with endorsements onto products just for quick money, some celebrities have gone beyond merely using their names and have put their entrepreneurial spirit to work by becoming entrepreneurs by attaching themselves in the business aspects of entertainment and building their own business brand beyond their traditional salaried activities. Along with investing their salaried wages into growing business endeavors, several celebrities have become innovative business leaders in their respective industries, gaining the admiration of their peers and contributing to the country's economy.
Numerous celebrities have ventured into becoming business moguls and established themselves as entrepreneurs, idolizing many well known business leaders such as Bill Gates, Richard Branson and Warren Buffett. For instance, former basketball player Michael Jordan became an entrepreneur involved with many sports-related ventures including investing a minority stake in the Charlotte Bobcats, Paul Newman started his own salad dressing business after leaving behind a distinguished acting career, and rap musician Birdman started his own record label, clothing line, and an oil business while maintaining a career as a rap artist. In 2014, David Beckham became co-owner of new Major League Soccer team Inter Miami, which began playing in 2020. Former Brazil striker and World Cup winner Ronaldo became the majority owner of La Liga club Real Valladolid in 2018. Other celebrities such as Tyler Perry, George Lucas, and Steven Spielberg have become successful entrepreneurs through starting their own film production companies and running their own movie studios beyond their traditional activities of screenwriting, directing, animating, producing, and acting.
Tabloid magazines and talk TV shows bestow a great deal of attention to celebrities. To stay in the public eye and build wealth in addition to their salaried labor, numerous celebrities have participating and branching into various business ventures and endorsements. Many celebrities have participated in many different endorsement opportunities that include: animation, publishing, fashion designing, cosmetics, consumer electronics, household items and appliances, cigarettes, soft drinks and alcoholic beverages, hair care, hairdressing, jewelry design, fast food, credit cards, video games, writing, and toys.
In addition to various endorsements, some celebrities have been involved with some business and investment-related ventures also include: and toddler related items, sports team ownership, fashion retailing, establishments such as restaurants, cafes, hotels, and casinos, movie theaters, advertising and event planning, management-related ventures such as sports management, financial services, model management, and talent management, record labels, film production, television production, publishing such as book and music publishing, massage therapy, salons, health and fitness, and real estate.
Although some celebrities have achieved additional financial success from various business ventures, the vast majority of celebrities are not successful businesspeople and still rely on salaried labored wages to earn a living. Most businesses and investments are well known to have a 90 to 95 percent failure rate within the first five years of operation. Not all celebrities eventually succeed with their businesses and other related side ventures. Some celebrities either went broke or filed for bankruptcy as a result of dabbling with such side businesses or endorsements. Though some might question such validity since celebrities themselves are already well known, have mass appeal, and are well exposed to the general public. The average entrepreneur who is not well known and reputable to the general public does not the same marketing flexibility and status-quo as most celebrities allow and have. Therefore, compared to the average person who starts a business, celebrities already have all the cards and odds stacked in their favor. This means they can have an unfair advantage to expose their business ventures and endorsements and can easily capture a more significant amount of market share than the average entrepreneur.
Celebrities often have fame comparable to royalty. As a result, there is a strong public curiosity about their private affairs. The release of Kim Kardashian's sex tape with rapper Ray J in 2003 brought her to a new level of fame, leading to magazine covers, book deals, and reality TV series.
Celebrities may be resented for their accolades, and the public may have a love/hate relationship with celebrities. Due to the high visibility of celebrities' private lives, their successes and shortcomings are often made very public. Celebrities are alternately portrayed as glowing examples of perfection, when they garner awards, or as decadent or immoral if they become associated with a scandal. When seen in a positive light, celebrities are frequently portrayed as possessing skills and abilities beyond average people; for example, celebrity actors are routinely celebrated for acquiring new skills necessary for filming a role within a very brief time, and to a level that amazes the professionals who train them. Similarly, some celebrities with very little formal education can sometimes be portrayed as experts on complicated issues. Some celebrities have been very vocal about their political views. For example, Matt Damon expressed his displeasure with 2008 US vice presidential nominee Sarah Palin, as well as with the 2011 United States debt-ceiling crisis.
Famous for being famous, in popular culture terminology, refers to someone who attains celebrity status for no particular identifiable reason, or who achieves fame through association with a celebrity. The term is a pejorative, suggesting the target has no particular talents or abilities. British journalist Malcolm Muggeridge made the first known usage of the phrase in the introduction to his book Muggeridge Through The Microphone: BBC Radio and Television (1967) in which he wrote:
In the past if someone was famous or notorious, it was for something—as a writer or an actor or a criminal; for some talent or distinction or abomination. Today one is famous for being famous. People who come up to one in the street or in public places to claim recognition nearly always say: "I've seen you on the telly!"
The coinages "famesque" and "celebutante" are of similar pejorative gist.
Also known as being internet famous.
A report by the BBC highlighted a longtime trend of Asian internet celebrities called Wanghong in Chinese. According to the BBC, there are two kinds of online celebrities in China—those who create original content, such as Papi Jiang, who is regularly censored by Chinese authorities for cursing in her videos, and Wanghongs fall under the second category, as they have clothing and cosmetics businesses on Taobao, China's equivalent of Amazon.
Most high-profile celebrities participate in social networking services and photo or video hosting platforms such as YouTube, Twitter, Facebook, Instagram, and Snapchat. Social networking services allow celebrities to communicate directly with their fans, removing the middle-man known as traditional media.Through social media many persons outside entertainment and sports sphere become celebrity in their own sphere. Social media humanizes celebrities in a way that arouses public fascination as evident by the success of magazines such as Us Weekly and People Weekly. Celebrity blogging have also spawned stars such as Perez Hilton who is well known for not only blogging but also outing celebrities.
Social media and the rise of the smartphone have changed how celebrities are treated and how people gain the platform of fame. Not everything is as concealed as it was back in old Hollywood because now everything is put out on the internet by fans or even the celebrity themselves. Websites like Twitter, Facebook, Instagram, and YouTube allow people to become a celebrity overnight. For example, Justin Bieber got his start on YouTube by posting videos of him singing and got discovered. All of his fans got direct contact with his content and were able to interact with him on several social media platforms. Social media has substantially changed what it means to be a celebrity. Instagram and YouTube allow regular people to become rich and famous all from inside their home. It also allows fans to connect with their favorite celebrity without ever meeting them in person. Everything is being shared on social media so it makes it harder for celebrities to live private lives.
Social media sites have also contributed to the fame of some celebrities, such as Tila Tequila who became known through MySpace.
Access to celebrities is strictly controlled by their entourage of staff which includes managers, publicists, agents, personal assistants, and bodyguards. Even journalists find it difficult to access celebrities for interviews. Writer and actor Michael Musto said, "You have to go through many hoops just to talk to a major celebrity. You have to get past three different sets of publicists: the publicist for the event, the publicist for the movie, and then the celebrity's personal publicist. They all have to approve you."
Celebrities also typically have security staff at their home, to protect them from similar threats.
"15 minutes of fame" is a phrase often used in reference to short-lived publicity, and mistakenly attributed to Andy Warhol. Certain "15 minutes of fame" celebrities can be average people seen with an A-list celebrity, who are sometimes noticed on entertainment news channels such as E! News. These persons are ordinary people becoming celebrities, often based on the ridiculous things they do. "In fact, many reality show contestants fall into this category: the only thing that qualifies them to be on TV is that they're real."
Common threats such as stalking have spawned celebrity worship syndrome where a person becomes overly involved with the details of a celebrity's personal life. Psychologists have indicated that though many people obsess over glamorous film, television, sport and music stars, the disparity in salaries in society seems to value professional athletes and entertainment industry-based professionals. One study found that singers, musicians, actors and athletes die younger on average than writers, composers, academics, politicians and businesspeople, with a greater incidence of cancer and especially lung cancer. However, it was remarked that the reasons for this remained unclear, with theories including innate tendencies towards risk-taking as well as the pressure or opportunities of particular types of fame.
Fame might have negative psychological effects, and may lead to increasingly selfish tendencies and psychopathy. An academic study on the subject said that fame has an addictive quality to it. When a celebrity's fame recedes over time, the celebrity may find it difficult to adjust psychologically.
Recently, there has been more attention toward the impact celebrities have on health decisions of the population at large. It is believed that the public will follow celebrities' health advice to some extent. This can have positive impacts when the celebrities give solid, evidence-informed health advice, however, it can also have detrimental effects if the health advice is not accurate enough. | [

] | Celebrity is a condition of fame and broad public recognition of a person or group as a result of the attention given to them by mass media. An individual may attain a celebrity status from having great wealth, their participation in sports or the entertainment industry, their position as a political figure, or even from their connection to another celebrity. 'Celebrity' usually implies a favorable public image, as opposed to the neutrals 'famous' or 'notable', or the negatives 'infamous' and 'notorious'. | 2001-07-04T15:28:27Z | 2023-12-17T00:12:18Z | [

5,797 | Cluster sampling | In statistics, cluster sampling is a sampling plan used when mutually homogeneous yet internally heterogeneous groupings are evident in a statistical population. It is often used in marketing research.
In this sampling plan, the total population is divided into these groups (known as clusters) and a simple random sample of the groups is selected. The elements in each cluster are then sampled. If all elements in each sampled cluster are sampled, then this is referred to as a "one-stage" cluster sampling plan. If a simple random subsample of elements is selected within each of these groups, this is referred to as a "two-stage" cluster sampling plan. A common motivation for cluster sampling is to reduce the total number of interviews and costs given the desired accuracy. For a fixed sample size, the expected random error is smaller when most of the variation in the population is present internally within the groups, and not between the groups.
The population within a cluster should ideally be as heterogeneous as possible, but there should be homogeneity between clusters. Each cluster should be a small-scale representation of the total population. The clusters should be mutually exclusive and collectively exhaustive. A random sampling technique is then used on any relevant clusters to choose which clusters to include in the study. In single-stage cluster sampling, all the elements from each of the selected clusters are sampled. In two-stage cluster sampling, a random sampling technique is applied to the elements from each of the selected clusters.
The main difference between cluster sampling and stratified sampling is that in cluster sampling the cluster is treated as the sampling unit so sampling is done on a population of clusters (at least in the first stage). In stratified sampling, the sampling is done on elements within each stratum. In stratified sampling, a random sample is drawn from each of the strata, whereas in cluster sampling only the selected clusters are sampled. A common motivation for cluster sampling is to reduce costs by increasing sampling efficiency. This contrasts with stratified sampling where the motivation is to increase precision.
There is also multistage cluster sampling, where at least two stages are taken in selecting elements from clusters.
Without modifying the estimated parameter, cluster sampling is unbiased when the clusters are approximately the same size. In this case, the parameter is computed by combining all the selected clusters. When the clusters are of different sizes there are several options:
One method is to sample clusters and then survey all elements in that cluster. Another method is a two-stage method of sampling a fixed proportion of units (be it 5% or 50%, or another number, depending on cost considerations) from within each of the selected clusters. Relying on the sample drawn from these options will yield an unbiased estimator. However, the sample size is no longer fixed upfront. This leads to a more complicated formula for the standard error of the estimator, as well as issues with the optics of the study plan (since the power analysis and the cost estimations often relate to a specific sample size).
A third possible solution is to use probability proportionate to size sampling. In this sampling plan, the probability of selecting a cluster is proportional to its size, so a large cluster has a greater probability of selection than a small cluster. The advantage here is that when clusters are selected with probability proportionate to size, the same number of interviews should be carried out in each sampled cluster so that each unit sampled has the same probability of selection.
An example of cluster sampling is area sampling or geographical cluster sampling. Each cluster is a geographical area. Because a geographically dispersed population can be expensive to survey, greater economy than simple random sampling can be achieved by grouping several respondents within a local area into a cluster. It is usually necessary to increase the total sample size to achieve equivalent precision in the estimators, but cost savings may make such an increase in sample size feasible.
Cluster sampling is used to estimate low mortalities in cases such as wars, famines and natural disasters.
It is almost impossible to take a simple random sample of fish from a population, which would require that individuals are captured individually and at random. This is because fishing gears capture fish in groups (or clusters).
In commercial fisheries sampling, the costs of operating at sea are often too large to select hauls individually and at random. Therefore, observations are further clustered by either vessel or fishing trip.
Major use: when the sampling frame of all elements is not available we can resort only to cluster sampling.
Two-stage cluster sampling, a simple case of multistage sampling, is obtained by selecting cluster samples in the first stage and then selecting a sample of elements from every sampled cluster. Consider a population of N clusters in total. In the first stage, n clusters are selected using the ordinary cluster sampling method. In the second stage, simple random sampling is usually used. It is used separately in every cluster and the numbers of elements selected from different clusters are not necessarily equal. The total number of clusters N, the number of clusters selected n, and the numbers of elements from selected clusters need to be pre-determined by the survey designer. Two-stage cluster sampling aims at minimizing survey costs and at the same time controlling the uncertainty related to estimates of interest. This method can be used in health and social sciences. For instance, researchers used two-stage cluster sampling to generate a representative sample of the Iraqi population to conduct mortality surveys. Sampling in this method can be quicker and more reliable than other methods, which is why this method is now used frequently.
Cluster sampling methods can lead to significant bias when working with a small number of clusters. For instance, it can be necessary to cluster at the state or city-level, units that may be small and fixed in number. Microeconometrics methods for panel data often use short panels, which is analogous to having few observations per clusters and many clusters. The small cluster problem can be viewed as an incidental parameter problem. While the point estimates can be reasonably precisely estimated, if the number of observations per cluster is sufficiently high, we need the number of clusters G → ∞ {\displaystyle G\rightarrow \infty } for the asymptotics to kick in. If the number of clusters is low the estimated covariance matrix can be downward biased.
Small numbers of clusters are a risk when there is serial correlation or when there is intraclass correlation as in the Moulton context. When having few clusters, we tend to underestimate serial correlation across observations when a random shock occurs, or the intraclass correlation in a Moulton setting. Several studies have highlighted the consequences of serial correlation and highlighted the small-cluster problem.
In the framework of the Moulton factor, an intuitive explanation of the small cluster problem can be derived from the formula for the Moulton factor. Assume for simplicity that the number of observations per cluster is fixed at n. Below, V c ( β ) {\displaystyle V_{c}(\beta )} stands for the covariance matrix adjusted for clustering, V ( β ) {\displaystyle V(\beta )} stands for the covariance matrix not adjusted for clustering, and ρ stands for the intraclass correlation:
The ratio on the left-hand side indicates how much the unadjusted scenario overestimates the precision. Therefore, a high number means a strong downward bias of the estimated covariance matrix. A small cluster problem can be interpreted as a large n: when the data is fixed and the number of clusters is low, the number of data within a cluster can be high. It follows that inference, when the number of clusters is small, will not have the correct coverage.
Several solutions for the small cluster problem have been proposed. One can use a bias-corrected cluster-robust variance matrix, make T-distribution adjustments, or use bootstrap methods with asymptotic refinements, such as the percentile-t or wild bootstrap, that can lead to improved finite sample inference. Cameron, Gelbach and Miller (2008) provide microsimulations for different methods and find that the wild bootstrap performs well in the face of a small number of clusters. | [

"text": "Two-stage cluster sampling, a simple case of multistage sampling, is obtained by selecting cluster samples in the first stage and then selecting a sample of elements from every sampled cluster. Consider a population of N clusters in total. In the first stage, n clusters are selected using the ordinary cluster sampling method. In the second stage, simple random sampling is usually used. It is used separately in every cluster and the numbers of elements selected from different clusters are not necessarily equal. The total number of clusters N, the number of clusters selected n, and the numbers of elements from selected clusters need to be pre-determined by the survey designer. Two-stage cluster sampling aims at minimizing survey costs and at the same time controlling the uncertainty related to estimates of interest. This method can be used in health and social sciences. For instance, researchers used two-stage cluster sampling to generate a representative sample of the Iraqi population to conduct mortality surveys. Sampling in this method can be quicker and more reliable than other methods, which is why this method is now used frequently.",

] | In statistics, cluster sampling is a sampling plan used when mutually homogeneous yet internally heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this sampling plan, the total population is divided into these groups and a simple random sample of the groups is selected. The elements in each cluster are then sampled. If all elements in each sampled cluster are sampled, then this is referred to as a "one-stage" cluster sampling plan. If a simple random subsample of elements is selected within each of these groups, this is referred to as a "two-stage" cluster sampling plan. A common motivation for cluster sampling is to reduce the total number of interviews and costs given the desired accuracy. For a fixed sample size, the expected random error is smaller when most of the variation in the population is present internally within the groups, and not between the groups. | 2001-03-24T16:06:46Z | 2023-11-26T02:32:36Z | [

5,804 | Charles Baudelaire | Charles Pierre Baudelaire (UK: /ˈboʊdəlɛər/, US: /ˌboʊd(ə)ˈlɛər/; French: [ʃaʁl(ə) bodlɛʁ] ; 9 April 1821 – 31 August 1867) was a French poet who also worked as an essayist, art critic and translator. His poems are described as exhibiting mastery of rhyme and rhythm, containing an exoticism inherited from Romantics, and are based on observations of real life.
His most famous work, a book of lyric poetry titled Les Fleurs du mal (The Flowers of Evil), expresses the changing beauty of nature in the rapidly industrialising Paris caused by Haussmann's renovation of Paris during the mid-19th century. Baudelaire's original style of prose-poetry influenced a generation of poets including Paul Verlaine, Arthur Rimbaud and Stéphane Mallarmé. He coined the term modernity (modernité) to designate the fleeting experience of life in an urban metropolis, and the responsibility of artistic expression to capture that experience. Marshall Berman has credited Baudelaire as being the first Modernist.
Baudelaire was born in Paris, France, on 9 April 1821, and baptized two months later at Saint-Sulpice Roman Catholic Church. His father, Joseph-François Baudelaire (1759–1827), a senior civil servant and amateur artist, who at 60, was 34 years older than Baudelaire's 26-year-old mother, Caroline (née Dufaÿs) (1794–1871); she was his second wife.
Joseph-François died during Baudelaire's childhood, at rue Hautefeuille, Paris, on 10 February 1827. The following year, Caroline married Lieutenant Colonel Jacques Aupick [fr], who later became a French ambassador to various noble courts.
Baudelaire's biographers have often seen this as a crucial moment, considering that finding himself no longer the sole focus of his mother's affection left him with a trauma, which goes some way to explaining the excesses later apparent in his life. He stated in a letter to her that, "There was in my childhood a period of passionate love for you." Baudelaire regularly begged his mother for money throughout his career, often promising that a lucrative publishing contract or journalistic commission was just around the corner.
Baudelaire was educated in Lyon, where he boarded. At 14, he was described by a classmate as "much more refined and distinguished than any of our fellow pupils...we are bound to one another...by shared tastes and sympathies, the precocious love of fine works of literature."
Baudelaire was erratic in his studies, at times diligent, at other times prone to "idleness". Later, he attended the Lycée Louis-le-Grand in Paris, studying law, a popular course for those not yet decided on any particular career. He began to frequent prostitutes and may have contracted gonorrhea and syphilis during this period. He also began to run up debts, mostly for clothes.
Upon gaining his degree in 1839, he told his brother "I don't feel I have a vocation for anything." His stepfather had in mind a career in law or diplomacy, but instead Baudelaire decided to embark upon a literary career. His mother later recalled: "Oh, what grief! If Charles had let himself be guided by his stepfather, his career would have been very different...He would not have left a name in literature, it is true, but we should have been happier, all three of us."
His stepfather sent him on a voyage to Calcutta, India in 1841 in the hope of ending his dissolute habits. The trip provided strong impressions of the sea, sailing, and exotic ports, that he later employed in his poetry. Baudelaire later exaggerated his aborted trip to create a legend about his youthful travels and experiences, including "riding on elephants".
On returning to the taverns of Paris, he began to compose some of the poems of "Les Fleurs du Mal". At 21, he received a sizable inheritance but squandered much of it within a few years. His family obtained a decree to place his property in trust, which he resented bitterly, at one point arguing that allowing him to fail financially would have been the one sure way of teaching him to keep his finances in order.
Baudelaire became known in artistic circles as a dandy and free-spender, going through much of his inheritance and allowance in a short period of time. During this time, Jeanne Duval, a Haitian born actress became his mistress. She was rejected by his family. His mother thought Duval a "Black Venus" who "tortured him in every way" and drained him of money at every opportunity. Baudelaire made a suicide attempt during this period.
He took part in the Revolutions of 1848 and wrote for a revolutionary newspaper. However, his interest in politics was passing, as he was later to note in his journals.
In the early 1850s, Baudelaire struggled with poor health, pressing debts, and irregular literary output. He often moved from one lodging to another to escape creditors. He undertook many projects that he was unable to complete, though he did finish translations of stories by Edgar Allan Poe.
Upon the death of his stepfather in 1857, Baudelaire received no mention in the will but he was heartened nonetheless that the division with his mother might now be mended. At 36, he wrote to her: "believe that I belong to you absolutely, and that I belong only to you." His mother died on 16 August 1871, outliving her son by almost four years.
His first published work, under the pseudonym Baudelaire Dufaÿs, was his art review "Salon of 1845", which attracted immediate attention for its boldness. Many of his critical opinions were novel in their time, including his championing of Delacroix, and some of his views seem remarkably in tune with the future theories of the Impressionist painters.
In 1846, Baudelaire wrote his second Salon review, gaining additional credibility as an advocate and critic of Romanticism. His continued support of Delacroix as the foremost Romantic artist gained widespread notice. The following year Baudelaire's novella La Fanfarlo was published.
Baudelaire was a slow and very attentive worker. However, he often was sidetracked by indolence, emotional distress and illness, and it was not until 1857 that he published Les Fleurs du mal (The Flowers of Evil), his first and most famous volume of poems. Some of these poems had already appeared in the Revue des deux mondes (Review of Two Worlds) in 1855, when they were published by Baudelaire's friend Auguste Poulet-Malassis. Some of the poems had appeared as "fugitive verse" in various French magazines during the previous decade.
The poems found a small, yet appreciative audience. However, greater public attention was given to their subject matter. The effect on fellow artists was, as Théodore de Banville stated, "immense, prodigious, unexpected, mingled with admiration and with some indefinable anxious fear". Gustave Flaubert, recently attacked in a similar fashion for Madame Bovary (and acquitted), was impressed and wrote to Baudelaire: "You have found a way to rejuvenate Romanticism...You are as unyielding as marble, and as penetrating as an English mist."
The principal themes of sex and death were considered scandalous for the period. He also touched on lesbianism, sacred and profane love, metamorphosis, melancholy, the corruption of the city, lost innocence, the oppressiveness of living, and wine. Notable in some poems is Baudelaire's use of imagery of the sense of smell and of fragrances, which is used to evoke feelings of nostalgia and past intimacy.
The book, however, quickly became a byword for unwholesomeness among mainstream critics of the day. Some critics called a few of the poems "masterpieces of passion, art and poetry," but other poems were deemed to merit no less than legal action to suppress them. J. Habas led the charge against Baudelaire, writing in Le Figaro: "Everything in it which is not hideous is incomprehensible, everything one understands is putrid." Baudelaire responded to the outcry in a prophetic letter to his mother:
"You know that I have always considered that literature and the arts pursue an aim independent of morality. Beauty of conception and style is enough for me. But this book, whose title (Fleurs du mal) says everything, is clad, as you will see, in a cold and sinister beauty. It was created with rage and patience. Besides, the proof of its positive worth is in all the ill that they speak of it. The book enrages people. Moreover, since I was terrified myself of the horror that I should inspire, I cut out a third from the proofs. They deny me everything, the spirit of invention and even the knowledge of the French language. I don't care a rap about all these imbeciles, and I know that this book, with its virtues and its faults, will make its way in the memory of the lettered public, beside the best poems of V. Hugo, Th. Gautier and even Byron."
Baudelaire, his publisher and the printer were successfully prosecuted for creating an offense against public morals. They were fined, but Baudelaire was not imprisoned. Six of the poems were suppressed, but printed later as Les Épaves (The Wrecks) (Brussels, 1866). Another edition of Les Fleurs du mal, without these poems, but with considerable additions, appeared in 1861. Many notables rallied behind Baudelaire and condemned the sentence. Victor Hugo wrote to him: "Your fleurs du mal shine and dazzle like stars...I applaud your vigorous spirit with all my might." Baudelaire did not appeal the judgment, but his fine was reduced. Nearly 100 years later, on 11 May 1949, Baudelaire was vindicated, the judgment officially reversed, and the six banned poems reinstated in France.
In the poem "Au lecteur" ("To the Reader") that prefaces Les Fleurs du mal, Baudelaire accuses his readers of hypocrisy and of being as guilty of sins and lies as the poet:
Baudelaire next worked on a translation and adaptation of Thomas De Quincey's Confessions of an English Opium-Eater. Other works in the years that followed included Petits Poèmes en prose (Small Prose poems); a series of art reviews published in the Pays, Exposition universelle (Country, World Fair); studies on Gustave Flaubert (in L'Artiste, 18 October 1857); on Théophile Gautier (Revue contemporaine, September 1858); various articles contributed to Eugène Crépet's Poètes français; Les Paradis artificiels: opium et haschisch (French poets; Artificial Paradises: opium and hashish) (1860); and Un Dernier Chapitre de l'histoire des oeuvres de Balzac (A Final Chapter of the history of works of Balzac) (1880), originally an article "Comment on paye ses dettes quand on a du génie" ("How one pays one's debts when one has genius"), in which his criticism turns against his friends Honoré de Balzac, Théophile Gautier, and Gérard de Nerval.
By 1859, his illnesses, his long-term use of laudanum, his life of stress, and his poverty had taken a toll and Baudelaire had aged noticeably. But at last, his mother relented and agreed to let him live with her for a while at Honfleur. Baudelaire was productive and at peace in the seaside town, his poem Le Voyage being one example of his efforts during that time. In 1860, he became an ardent supporter of Richard Wagner.
His financial difficulties increased again, however, particularly after his publisher Poulet Malassis went bankrupt in 1861. In 1864, he left Paris for Belgium, partly in the hope of selling the rights to his works and to give lectures. His long-standing relationship with Jeanne Duval continued on-and-off, and he helped her to the end of his life. Baudelaire's relationships with actress Marie Daubrun and with courtesan Apollonie Sabatier, though the source of much inspiration, never produced any lasting satisfaction. He smoked opium, and in Brussels he began to drink to excess. Baudelaire suffered a massive stroke in 1866 and paralysis followed. After more than a year of aphasia, he received the last rites of the Catholic Church. The last year of his life was spent in a semi-paralyzed state in various "maisons de santé" in Brussels and in Paris, where he died on 31 August 1867. Baudelaire is buried in the Cimetière du Montparnasse, Paris.
Many of Baudelaire's works were published posthumously. After his death, his mother paid off his substantial debts, and she found some comfort in Baudelaire's emerging fame. "I see that my son, for all his faults, has his place in literature." She lived another four years.
Who among us has not dreamt, in moments of ambition, of the miracle of a poetic prose, musical without rhythm and rhyme, supple and staccato enough to adapt to the lyrical stirrings of the soul, the undulations of dreams, and sudden leaps of consciousness. This obsessive idea is above all a child of giant cities, of the intersecting of their myriad relations.
Baudelaire is one of the major innovators in French literature. His poetry is influenced by the French romantic poets of the earlier 19th century, although its attention to the formal features of verse connects it more closely to the work of the contemporary "Parnassians". As for theme and tone, in his works we see the rejection of the belief in the supremacy of nature and the fundamental goodness of man as typically espoused by the romantics and expressed by them in rhetorical, effusive and public voice in favor of a new urban sensibility, an awareness of individual moral complexity, an interest in vice (linked with decadence) and refined sensual and aesthetic pleasures, and the use of urban subject matter, such as the city, the crowd, individual passers-by, all expressed in highly ordered verse, sometimes through a cynical and ironic voice. Formally, the use of sound to create atmosphere, and of "symbols" (images that take on an expanded function within the poem), betray a move towards considering the poem as a self-referential object, an idea further developed by the Symbolists Verlaine and Mallarmé, who acknowledge Baudelaire as a pioneer in this regard.
Beyond his innovations in versification and the theories of symbolism and "correspondences", an awareness of which is essential to any appreciation of the literary value of his work, aspects of his work that regularly receive much critical discussion include the role of women, the theological direction of his work and his alleged advocacy of "satanism", his experience of drug-induced states of mind, the figure of the dandy, his stance regarding democracy and its implications for the individual, his response to the spiritual uncertainties of the time, his criticisms of the bourgeois, and his advocacy of modern music and painting (e.g., Wagner, Delacroix). He made Paris the subject of modern poetry. He brought the city's details to life in the eyes and hearts of his readers.
Baudelaire was an active participant in the artistic life of his times. As critic and essayist, he wrote extensively and perceptively about the luminaries and themes of French culture. He was frank with friends and enemies, rarely took the diplomatic approach and sometimes responded violently verbally, which often undermined his cause. His associations were numerous, including Gustave Courbet, Honoré Daumier, Félicien Rops, Franz Liszt, Champfleury, Victor Hugo, Gustave Flaubert, and Balzac.
In 1847, Baudelaire became acquainted with the works of Poe, in which he found tales and poems that had, he claimed, long existed in his own brain but never taken shape. Baudelaire saw in Poe a precursor and tried to be his French contemporary counterpart. From this time until 1865, he was largely occupied with translating Poe's works; his translations were widely praised. Baudelaire was not the first French translator of Poe, but his "scrupulous translations" were considered among the best. These were published as Histoires extraordinaires (Extraordinary stories) (1856), Nouvelles histoires extraordinaires (New extraordinary stories) (1857), Aventures d'Arthur Gordon Pym, Eureka, and Histoires grotesques et sérieuses (Grotesque and serious stories) (1865). Two essays on Poe are to be found in his Œuvres complètes (Complete works) (vols. v. and vi.).
A strong supporter of the Romantic painter Delacroix, Baudelaire called him "a poet in painting". Baudelaire also absorbed much of Delacroix's aesthetic ideas as expressed in his journals. As Baudelaire elaborated in his "Salon of 1846", "As one contemplates his series of pictures, one seems to be attending the celebration of some grievous mystery...This grave and lofty melancholy shines with a dull light.. plaintive and profound like a melody by Weber." Delacroix, though appreciative, kept his distance from Baudelaire, particularly after the scandal of Les Fleurs du mal. In private correspondence, Delacroix stated that Baudelaire "really gets on my nerves" and he expressed his unhappiness with Baudelaire's persistent comments about "melancholy" and "feverishness".
Baudelaire had no formal musical training, and knew little of composers beyond Beethoven and Weber. Weber was in some ways Wagner's precursor, using the leitmotif and conceiving the idea of the "total art work" ("Gesamtkunstwerk"), both of which gained Baudelaire's admiration. Before even hearing Wagner's music, Baudelaire studied reviews and essays about him, and formulated his impressions. Later, Baudelaire put them into his non-technical analysis of Wagner, which was highly regarded, particularly his essay "Richard Wagner et Tannhäuser à Paris". Baudelaire's reaction to music was passionate and psychological. "Music engulfs (possesses) me like the sea." After attending three Wagner concerts in Paris in 1860, Baudelaire wrote to the composer: "I had a feeling of pride and joy in understanding, in being possessed, in being overwhelmed, a truly sensual pleasure like that of rising in the air." Baudelaire's writings contributed to the elevation of Wagner and to the cult of Wagnerism that swept Europe in the following decades.
Gautier, writer and poet, earned Baudelaire's respect for his perfection of form and his mastery of language, though Baudelaire thought he lacked deeper emotion and spirituality. Both strove to express the artist's inner vision, which Heinrich Heine earlier stated: "In artistic matters, I am a supernaturalist. I believe that the artist can not find all his forms in nature, but that the most remarkable are revealed to him in his soul." Gautier's frequent meditations on death and the horror of life are themes which influenced Baudelaire's writings. In gratitude for their friendship and commonality of vision, Baudelaire dedicated Les Fleurs du mal to Gautier.
Manet and Baudelaire became constant companions from around 1855. In the early 1860s, Baudelaire accompanied Manet on daily sketching trips and often met him socially. Manet also lent Baudelaire money and looked after his affairs, particularly when Baudelaire went to Belgium. Baudelaire encouraged Manet to strike out on his own path and not succumb to criticism. "Manet has great talent, a talent which will stand the test of time. But he has a weak character. He seems to me crushed and stunned by shock." In his painting Music in the Tuileries, Manet includes portraits of his friends Théophile Gautier, Jacques Offenbach, and Baudelaire. While it's difficult to differentiate who influenced whom, both Manet and Baudelaire discussed and expressed some common themes through their respective arts. Baudelaire praised the modernity of Manet's subject matter: "almost all our originality comes from the stamp that 'time' imprints upon our feelings." When Manet's famous Olympia (1865), a portrait of a nude prostitute, provoked a scandal for its blatant realism mixed with an imitation of Renaissance motifs, Baudelaire worked privately to support his friend, though he offered no public defense (he was, however, ill at the time). When Baudelaire returned from Belgium after his stroke, Manet and his wife were frequent visitors at the nursing home and she played passages from Wagner for Baudelaire on the piano.
Nadar (Félix Tournachon) was a noted caricaturist, scientist and important early photographer. Baudelaire admired Nadar, one of his close friends, and wrote: "Nadar is the most amazing manifestation of vitality." They moved in similar circles and Baudelaire made many social connections through him. Nadar's ex-mistress Jeanne Duval became Baudelaire's mistress around 1842. Baudelaire became interested in photography in the 1850s, and denouncing it as an art form, advocated its return to "its real purpose, which is that of being the servant to the sciences and arts". Photography should not, according to Baudelaire, encroach upon "the domain of the impalpable and the imaginary". Nadar remained a stalwart friend right to Baudelaire's last days and wrote his obituary notice in Le Figaro.
Many of Baudelaire's philosophical proclamations were considered scandalous and intentionally provocative in his time. He wrote on a wide range of subjects, drawing criticism and outrage from many quarters. Along with Poe, Baudelaire named the arch-reactionary Joseph de Maistre as his maître à penser and adopted increasingly aristocratic views. In his journals, he wrote:
"There is no form of rational and assured government save an aristocracy. […] There are but three beings worthy of respect: the priest, the warrior and the poet. To know, to kill and to create. The rest of mankind may be taxed and drudged, they are born for the stable, that is to say, to practise what they call professions."
Baudelaire's influence on the direction of modern French (and English) language literature was considerable. The most significant French writers to come after him were generous with tributes; four years after his death, Arthur Rimbaud praised him in a letter as "the king of poets, a true God". In 1895, Stéphane Mallarmé published "Le Tombeau de Charles Baudelaire", a sonnet in Baudelaire's memory. Marcel Proust, in an essay published in 1922, stated that, along with Alfred de Vigny, Baudelaire was "the greatest poet of the nineteenth century".
In the English-speaking world, Edmund Wilson credited Baudelaire as providing an initial impetus for the Symbolist movement by virtue of his translations of Poe. In 1930, T. S. Eliot, while asserting that Baudelaire had not yet received a "just appreciation" even in France, claimed that the poet had "great genius" and asserted that his "technical mastery which can hardly be overpraised...has made his verse an inexhaustible study for later poets, not only in his own language". In a lecture delivered in French on "Edgar Allan Poe and France" (Edgar Poe et la France) in Aix-en-Provence in April 1948, Eliot stated that "I am an English poet of American origin who learnt his art under the aegis of Baudelaire and the Baudelairian lineage of poets." Eliot also alluded to Baudelaire's poetry directly in his own poetry. For example, he quoted the last line of Baudelaire's "Au Lecteur" in the last line of Section I of The Waste Land.
At the same time that Eliot was affirming Baudelaire's importance from a broadly conservative and explicitly Christian viewpoint, left-wing critics such as Wilson and Walter Benjamin were able to do so from a dramatically different perspective. Benjamin translated Baudelaire's Tableaux Parisiens into German and published a major essay on translation as the foreword.
In the late 1930s, Benjamin used Baudelaire as a starting point and focus for Das Passagenwerk, his monumental attempt at a materialist assessment of 19th-century culture. For Benjamin, Baudelaire's importance lay in his anatomies of the crowd, of the city and of modernity. He says that, in Les Fleurs du mal, "the specific devaluation of the world of things, as manifested in the commodity, is the foundation of Baudelaire's allegorical intention."
François Porche published a poetry collection called Charles Baudelaire: Poetry Collection in memory of Baudelaire.
The novel A Singular Conspiracy (1974) by Barry Perowne is a fictional treatment of the unaccounted period in Edgar Allan Poe's life from January to May 1844, in which (among other things) Poe becomes involved with a young Baudelaire in a plot to expose Baudelaires' stepfather to blackmail, to free up Baudelaires' patrimony.
Vanderbilt University has "assembled one of the world's most comprehensive research collections on...Baudelaire". Les Fleurs du mal has a number of scholarly references. | [

His poetry is influenced by the French romantic poets of the earlier 19th century, although its attention to the formal features of verse connects it more closely to the work of the contemporary \"Parnassians\". As for theme and tone, in his works we see the rejection of the belief in the supremacy of nature and the fundamental goodness of man as typically espoused by the romantics and expressed by them in rhetorical, effusive and public voice in favor of a new urban sensibility, an awareness of individual moral complexity, an interest in vice (linked with decadence) and refined sensual and aesthetic pleasures, and the use of urban subject matter, such as the city, the crowd, individual passers-by, all expressed in highly ordered verse, sometimes through a cynical and ironic voice. Formally, the use of sound to create atmosphere, and of \"symbols\" (images that take on an expanded function within the poem), betray a move towards considering the poem as a self-referential object, an idea further developed by the Symbolists Verlaine and Mallarmé, who acknowledge Baudelaire as a pioneer in this regard.",

Baudelaire praised the modernity of Manet's subject matter: \"almost all our originality comes from the stamp that 'time' imprints upon our feelings.\" When Manet's famous Olympia (1865), a portrait of a nude prostitute, provoked a scandal for its blatant realism mixed with an imitation of Renaissance motifs, Baudelaire worked privately to support his friend, though he offered no public defense (he was, however, ill at the time).

] | Charles Pierre Baudelaire was a French poet who also worked as an essayist, art critic and translator. His poems are described as exhibiting mastery of rhyme and rhythm, containing an exoticism inherited from Romantics, and are based on observations of real life. His most famous work, a book of lyric poetry titled Les Fleurs du mal, expresses the changing beauty of nature in the rapidly industrialising Paris caused by Haussmann's renovation of Paris during the mid-19th century. Baudelaire's original style of prose-poetry influenced a generation of poets including Paul Verlaine, Arthur Rimbaud and Stéphane Mallarmé. He coined the term modernity (modernité) to designate the fleeting experience of life in an urban metropolis, and the responsibility of artistic expression to capture that experience. Marshall Berman has credited Baudelaire as being the first Modernist. | 2001-07-01T08:15:31Z | 2023-12-24T01:20:58Z | [

5,808 | Casey at the Bat | "Casey at the Bat: A Ballad of the Republic, Sung in the Year 1888" is a mock-heroic poem written in 1888 by Ernest Thayer. It was first published anonymously in The San Francisco Examiner (then called The Daily Examiner) on June 3, 1888, under the pen name "Phin", based on Thayer's college nickname, "Phinney". Featuring a dramatic narrative about a baseball game, the poem was later popularized by DeWolf Hopper in many vaudeville performances. It has become one of the best-known poems in American literature.
A baseball team from the fictional town of "Mudville" (the home team) is losing by two runs in its last inning. Both the team and its fans, a crowd of 5,000, believe that they can win if Casey, Mudville's star player, gets to bat. However, Casey is scheduled to be the fifth batter of the inning, and the first two batters (Cooney and Barrows) fail to get on base. The next two batters (Flynn and Jimmy Blake) are perceived to be weak hitters with little chance of reaching base to allow Casey a chance to bat.
Surprisingly, Flynn hits a single, and Blake follows with a double that allows Flynn to reach third base. Both runners are now in scoring position and Casey represents the potential winning run. Casey is so sure of his abilities that he does not swing at the first two pitches, both called strikes. On the last pitch, the overconfident Casey strikes out swinging, ending the game and sending the crowd home unhappy.
The text is filled with references to baseball as it was in 1888, which in many ways is not far removed from today's version. As a work, the poem encapsulates much of the appeal of baseball, including the involvement of the crowd. It also has a fair amount of baseball jargon that can pose challenges for the uninitiated.
This is the complete poem as it originally appeared in The Daily Examiner. After publication, various versions with minor changes were produced.
No one imagines that 'Casey' is great in the sense that the poetry of Shakespeare or Dante is great; a comic ballad obviously must be judged by different standards. One doesn’t criticize a slice of superb apple pie because it fails to taste like crepes suzette. Thayer was only trying to write a comic ballad, with clanking rhymes and a vigorous beat, that could be read quickly, understood at once, and laughed at by any newspaper reader who knew baseball. Somehow, in harmony with the curious laws of humor and popular taste, he managed to produce the nation's best-known piece of comic verse—a ballad that began a native legend as colorful and permanent as that of Johnny Appleseed or Paul Bunyan.
Martin Gardner, American Heritage
The outlook wasn't brilliant for the Mudville nine that day; the score stood four to two, with but one inning more to play. And then when Cooney died at first, and Barrows did the same, a sickly silence fell upon the patrons of the game. A straggling few got up to go in deep despair. The rest clung to that hope which springs eternal in the human breast; they thought, if only Casey could get but a whack at that – they'd put up even money, now, with Casey at the bat. But Flynn preceded Casey, as did also Jimmy Blake, and the former was a lulu and the latter was a cake, so upon that stricken multitude grim melancholy sat, for there seemed but little chance of Casey's getting to the bat. But Flynn let drive a single, to the wonderment of all, and Blake, the much despised, tore the cover off the ball; and when the dust had lifted, and the men saw what had occurred, there was Jimmy safe at second and Flynn a-hugging third. Then from five thousand throats and more there rose a lusty yell; it rumbled through the valley, it rattled in the dell; it knocked upon the mountain and recoiled upon the flat, for Casey, mighty Casey, was advancing to the bat. There was ease in Casey's manner as he stepped into his place; there was pride in Casey's bearing and a smile on Casey's face. And when, responding to the cheers, he lightly doffed his hat, no stranger in the crowd could doubt 'twas Casey at the bat. Ten thousand eyes were on him as he rubbed his hands with dirt; five thousand tongues applauded when he wiped them on his shirt. Then while the writhing pitcher ground the ball into his hip, defiance gleamed in Casey's eye, a sneer curled Casey's lip. And now the leather-covered sphere came hurtling through the air, and Casey stood a-watching it in haughty grandeur there. Close by the sturdy batsman the ball unheeded sped— "That ain't my style," said Casey. "Strike one," the umpire said. From the benches, black with people, there went up a muffled roar, like the beating of the storm-waves on a stern and distant shore. "Kill him! Kill the umpire!" shouted someone on the stand; and it's likely they'd have killed him had not Casey raised his hand. With a smile of Christian charity great Casey's visage shone; he stilled the rising tumult; he bade the game go on; he signaled to the pitcher, and once more the spheroid flew; but Casey still ignored it, and the umpire said: "Strike two." "Fraud!" cried the maddened thousands, and Echo answered fraud; but one scornful look from Casey and the audience was awed. They saw his face grow stern and cold, they saw his muscles strain, and they knew that Casey wouldn't let that ball go by again. The sneer is gone from Casey's lip, his teeth are clenched in hate; he pounds with cruel violence his bat upon the plate. And now the pitcher holds the ball, and now he lets it go, and now the air is shattered by the force of Casey's blow. Oh, somewhere in this favored land the sun is shining bright; the band is playing somewhere, and somewhere hearts are light, and somewhere men are laughing, and somewhere children shout; but there is no joy in Mudville—mighty Casey has struck out.
Thayer said he chose the name "Casey" after a non-player of Irish ancestry he once knew named Daniel H. Casey; it is open to debate whom, if anyone, he modeled the character after. It has been reported that Thayer's best friend Samuel Winslow, who played baseball at Harvard, was the inspiration for Casey.
Another candidate is National League player Mike "King" Kelly, who became famous when Boston paid Chicago a record $10,000 for him. He had a personality that fans liked to cheer or jeer. After the 1887 season, Kelly went on a playing tour to San Francisco. Thayer, who wrote "Casey" in 1888, covered the San Francisco leg for the San Francisco Examiner.
Thayer, in a letter he wrote in 1905, mentions Kelly as showing "impudence" in claiming to have written the poem. The author of the 2004 definitive biography of Kelly—which included a close tracking of his vaudeville career—did not find Kelly claiming to have been the author.
"Casey at the Bat" was first published in The Daily Examiner on June 3, 1888.
A month after the poem was published, it was reprinted as "Kelly at the Bat" in the New York Sporting Times. Aside from omitting the first five verses, the only changes from the original are substitutions of Kelly for Casey, and Boston for Mudville. King Kelly, then of the Boston Beaneaters, was one of baseball's two biggest stars at the time (along with Cap Anson).
In 1897, the magazine Current Literature noted the two versions and said, "The locality, as originally given, is Mudville, not Boston; the latter was substituted to give the poem local color."
DeWolf Hopper gave the poem's first stage recitation on August 14, 1888, at New York's Wallack Theatre as part of the comic opera Prinz Methusalem in the presence of the Chicago White Stockings and New York Giants baseball teams; August 14, 1888 was also Thayer's 25th birthday. Hopper became known as an orator of the poem, and recited it more than 10,000 times (by his count—some tabulations are as much as four times higher) before his death.
"It is as perfect an epitome of our national game today as it was when every player drank his coffee from a mustache cup. There are one or more Caseys in every league, bush or big, and there is no day in the playing season that this same supreme tragedy, as stark as Aristophanes for the moment, does not befall on some field."
On stage in the early 1890s, baseball star Kelly recited the original "Casey" a few dozen times and not the parody. For example, in a review in 1893 of a variety show he was in, the Indianapolis News said, "Many who attended the performance had heard of Kelly's singing and his reciting, and many had heard De Wolf Hopper recite 'Casey at the Bat' in his inimitable way. Kelly recited this in a sing-song, school-boy fashion." Upon Kelly's death, a writer would say he gained "considerable notoriety by his ludicrous rendition of 'Casey at the Bat,' with which he concluded his 'turn' [act] at each performance."
During the 1980s, the magic/comedy team Penn & Teller performed a version of "Casey at the Bat" with Teller (the "silent" partner) struggling to escape a straitjacket while suspended upside-down over a platform of sharp steel spikes. The set-up was that Penn Jillette would leap off his chair upon finishing the poem, releasing the rope which supported Teller, and send Teller to a gruesome death if Teller had failed to free himself by that time. Jillette enhanced the drama of the performance by drastically accelerating the pace of his recital after the first few stanzas, greatly reducing the time that Teller had left to work free from his bonds.
The first recorded version of "Casey at the Bat" was made by Russell Hunting, speaking in a broad Irish accent, in 1893; an 1898 cylinder recording of the text made for the Columbia Graphophone label by Hunting can be accessed from the Cylinder Preservation and Digitization Project at the University of California, Santa Barbara Library.
DeWolf Hopper's more famous recorded recitation was released in October 1906.
In 1946, Walt Disney released a recording of the narration of the poem by Jerry Colonna, which accompanied the studio's animated cartoon adaptation of the poem (see below).
In 1973, the Cincinnati Symphony Orchestra commissioned its former Composer-in-Residence, Frank Proto, to create a work to feature Baseball Hall-of-Famer Johnny Bench with the orchestra. The result "Casey At The Bat – an American Folk Tale for Narrator and Orchestra" was an immediate hit and recorded by Bench and the orchestra. It has since been performed more than 800 times by nearly every major and Metropolitan orchestra in the U.S. and Canada.
In 1980, baseball pitcher Tug McGraw recorded Casey at The Bat—an American Folk Tale for Narrator and Orchestra by Frank Proto with Peter Nero and the Philly Pops.
In 1996, actor James Earl Jones recorded the poem with arranger/composer Steven Reineke and the Cincinnati Pops Orchestra.
On a 1997 CD set with memorable moments and stories from the game of baseball titled Take Me Out to the Ball Game produced by Jerry Hoffman and Douglas Duer, a Vincent Price oration of the poem is a slightly altered version of the original.
In 1998, actor Sir Derek Jacobi recorded the poem with composer/arranger Randol Alan Bass and the National Symphony of London, with the composer conducting. This work, titled "Casey at the Bat", has been recorded by the Boston Pops Orchestra, Keith Lockhart conducting. In 2013, Dave Jageler and Charlie Slowes, both radio announcers for the Washington Nationals, each made recordings of the poem for the Library of Congress to mark the 125th anniversary of its first publication.
In 2022 The Rose Theatre Co. recorded it as an episode on The Rose Rhapsody podcast featuring a performance by veteran DC actor and vocal artist Jim Brady.
A rivalry of sorts has developed between two cities claiming to be the Mudville described in the poem.
Residents of Holliston, Massachusetts, where there is a neighborhood called Mudville, claim it as the Mudville described in the poem. Thayer grew up in nearby Worcester, Massachusetts, where he wrote the poem in 1888; his family owned a wool mill less than 1 mi (1.6 km) from Mudville's baseball field.
However, residents of Stockton, California—which was known for a time as Mudville prior to incorporation in 1850—also lay claim to being the inspiration for the poem. In 1887, Thayer covered baseball for The Daily Examiner—owned by his Harvard classmate William Randolph Hearst—and is said to have covered the local California League team, the Stockton Ports. For the 1902 season, after the poem became popular, Stockton's team was renamed the Mudville Nine. The team reverted to the Mudville Nine moniker for the 2000 and 2001 seasons. The Visalia Rawhide, another California League team, currently keeps Mudville alive playing in Mudville jerseys on June 3 each year.
Despite the towns' rival claims, Thayer himself told the Syracuse Post-Standard that "the poem has no basis in fact."
The poem has been adapted to diverse types of media:
For a relatively short poem apparently dashed off quickly (and denied by its author for years), "Casey at the Bat" had a profound effect on American popular culture. It has been recited, re-enacted, adapted, dissected, parodied, and subjected to just about every other treatment one could imagine.
Of the many parodies made of the poem, some of the notable ones include:
There are three known translations of the poem into a foreign language, one in French, written in 2007 by French Canadian linguist Paul Laurendeau, with the title Casey au bâton, and two in Hebrew. One by the sports journalist Menachem Less titled "התור של קייסי לחבוט" [Hator Shel Casey Lachbot], and the other more recent and more true to the original cadence and style by Jason H. Elbaum called קֵיסִי בַּמַּחְבֵּט [Casey BaMachbayt].
Casey Stengel describes in his autobiography how his original nickname "K.C." (for his hometown, Kansas City, Missouri) evolved into "Casey". It was influenced not just by the name of the poem, which was widely popular in the 1910s, but also because he tended to strike out frequently in his early career so fans and writers started calling him "strikeout Casey".
On July 11, 1996, the United States Postal Service issued a commemorative stamp depicting "Mighty Casey." The stamp was part of a set commemorating American folk heroes. Other stamps in the set depicted Paul Bunyan, John Henry, and Pecos Bill. | [

And then when Cooney died at first, and Barrows did the same, a sickly silence fell upon the patrons of the game. A straggling few got up to go in deep despair. The rest clung to that hope which springs eternal in the human breast; they thought, if only Casey could get but a whack at that – they'd put up even money, now, with Casey at the bat. But Flynn preceded Casey, as did also Jimmy Blake, and the former was a lulu and the latter was a cake, so upon that stricken multitude grim melancholy sat, for there seemed but little chance of Casey's getting to the bat. But Flynn let drive a single, to the wonderment of all, and Blake, the much despised, tore the cover off the ball; and when the dust had lifted, and the men saw what had occurred, there was Jimmy safe at second and Flynn a-hugging third. Then from five thousand throats and more there rose a lusty yell; it rumbled through the valley, it rattled in the dell; it knocked upon the mountain and recoiled upon the flat, for Casey, mighty Casey, was advancing to the bat. There was ease in Casey's manner as he stepped into his place; there was pride in Casey's bearing and a smile on Casey's face. And when, responding to the cheers, he lightly doffed his hat, no stranger in the crowd could doubt 'twas Casey at the bat. Ten thousand eyes were on him as he rubbed his hands with dirt; five thousand tongues applauded when he wiped them on his shirt. Then while the writhing pitcher ground the ball into his hip, defiance gleamed in Casey's eye, a sneer curled Casey's lip. And now the leather-covered sphere came hurtling through the air, and Casey stood a-watching it in haughty grandeur there. Close by the sturdy batsman the ball unheeded sped— \"That ain't my style,\" said Casey. \"Strike one,\" the umpire said. From the benches, black with people, there went up a muffled roar, like the beating of the storm-waves on a stern and distant shore. \"Kill him! Kill the umpire!\" shouted someone on the stand; and it's likely they'd have killed him had not Casey raised his hand. With a smile of Christian charity great Casey's visage shone; he stilled the rising tumult; he bade the game go on; he signaled to the pitcher, and once more the spheroid flew; but Casey still ignored it, and the umpire said: \"Strike two.\" \"Fraud!\" cried the maddened thousands, and Echo answered fraud; but one scornful look from Casey and the audience was awed. They saw his face grow stern and cold, they saw his muscles strain, and they knew that Casey wouldn't let that ball go by again. The sneer is gone from Casey's lip, his teeth are clenched in hate; he pounds with cruel violence his bat upon the plate. And now the pitcher holds the ball, and now he lets it go, and now the air is shattered by the force of Casey's blow. Oh, somewhere in this favored land the sun is shining bright; the band is playing somewhere, and somewhere hearts are light, and somewhere men are laughing, and somewhere children shout; but there is no joy in Mudville—mighty Casey has struck out.",

5,810 | Classical guitar | The classical guitar, also called Spanish guitar, is a member of the guitar family used in classical music and other styles. An acoustic wooden string instrument with strings made of gut or nylon, it is a precursor of the modern steel-string acoustic and electric guitars, both of which use metal strings. Classical guitars derive from the Spanish vihuela and gittern of the 15th and 16th century. Those instruments evolved into the 17th and 18th-century baroque guitar—and by the mid-19th century, early forms of the modern classical guitar. Today's modern classical guitar was established by the late designs of the 19th-century Spanish luthier, Antonio Torres Jurado.
For a right-handed player, the traditional classical guitar has 12 frets clear of the body and is properly held up by the left leg, so that the hand that plucks or strums the strings does so near the back of the sound hole (this is called the classical position). However, the right-hand may move closer to the fretboard to achieve different tonal qualities. The player typically holds the left leg higher by the use of a foot rest. The modern steel string guitar, on the other hand, usually has 14 frets clear of the body (see Dreadnought) and is commonly held with a strap around the neck and shoulder.
The phrase "classical guitar" may refer to either of two concepts other than the instrument itself:
The term modern classical guitar sometimes distinguishes the classical guitar from older forms of guitar, which are in their broadest sense also called classical, or more specifically, early guitars. Examples of early guitars include the six-string early romantic guitar (c. 1790 – 1880), and the earlier baroque guitars with five courses.
The materials and the methods of classical guitar construction may vary, but the typical shape is either modern classical guitar or that historic classical guitar similar to the early romantic guitars of France and Italy. Classical guitar strings once made of gut are now made of materials such as nylon or fluoropolymers, typically with silver-plated copper fine wire wound about the acoustically lower (d-A-E in standard tuning) strings.
A guitar family tree may be identified. The flamenco guitar derives from the modern classical, but has differences in material, construction and sound.
The classical guitar has a long history and one is able to distinguish various:
Both instrument and repertoire can be viewed from a combination of various perspectives:
Historical (chronological period of time)
Geographical
Cultural
While "classical guitar" is today mainly associated with the modern classical guitar design, there is an increasing interest in early guitars; and understanding the link between historical repertoire and the particular period guitar that was originally used to perform this repertoire. The musicologist and author Graham Wade writes:
Nowadays it is customary to play this repertoire on reproductions of instruments authentically modelled on concepts of musicological research with appropriate adjustments to techniques and overall interpretation. Thus over recent decades we have become accustomed to specialist artists with expertise in the art of vihuela (a 16th-century type of guitar popular in Spain), lute, Baroque guitar, 19th-century guitar, etc.
Different types of guitars have different sound aesthetics, e.g. different colour-spectrum characteristics (the way the sound energy is spread in the fundamental frequency and the overtones), different response, etc. These differences are due to differences in construction; for example, modern classical guitars usually use a different bracing (fan-bracing) from that used in earlier guitars (they had ladder-bracing); and a different voicing was used by the luthier.
There is a historical parallel between musical styles (baroque, classical, romantic, flamenco, jazz) and the style of "sound aesthetic" of the musical instruments used, for example: Robert de Visée played a baroque guitar with a very different sound aesthetic from the guitars used by Mauro Giuliani and Luigi Legnani – they used 19th-century guitars. These guitars in turn sound different from the Torres models used by Segovia that are suited for interpretations of romantic-modern works such as Moreno Torroba.
When considering the guitar from a historical perspective, the musical instrument used is as important as the musical language and style of the particular period. As an example: It is impossible to play a historically informed de Visee or Corbetta (baroque guitarist-composers) on a modern classical guitar. The reason is that the baroque guitar used courses, which are two strings close together (in unison), that are plucked together. This gives baroque guitars an unmistakable sound characteristic and tonal texture that is an integral part of an interpretation. Additionally, the sound aesthetic of the baroque guitar (with its strong overtone presence) is very different from modern classical type guitars, as is shown below.
Today's use of Torres and post-Torres type guitars for repertoire of all periods is sometimes critically viewed: Torres and post-Torres style modern guitars (with their fan-bracing and design) have a thick and strong tone, very suitable for modern-era repertoire. However, they are considered to emphasize the fundamental too heavily (at the expense of overtone partials) for earlier repertoire (Classical/Romantic: Carulli, Sor, Giuliani, Mertz, ...; Baroque: de Visee, ...; etc.). "Andrés Segovia presented the Spanish guitar as a versatile model for all playing styles" to the extent, that still today, "many guitarists have tunnel-vision of the world of the guitar, coming from the modern Segovia tradition".
While fan-braced modern classical Torres and post-Torres style instruments coexisted with traditional ladder-braced guitars at the beginning of the 20th century, the older forms eventually fell away. Some attribute this to the popularity of Segovia, considering him "the catalyst for change toward the Spanish design and the so-called 'modern' school in the 1920s and beyond." The styles of music performed on ladder-braced guitars were becoming unfashionable—and, e.g., in Germany, more musicians were turning towards folk music (Schrammel-music and the Contraguitar). This was localized in Germany and Austria and became unfashionable again. On the other hand, Segovia was playing concerts around the world, popularizing modern classical guitar—and, in the 1920s, Spanish romantic-modern style with guitar works by Moreno Torroba, de Falla, etc.
The 19th-century classical guitarist Francisco Tárrega first popularized the Torres design as a classical solo instrument. However, some maintain that Segovia's influence led to its domination over other designs. Factories around the world began producing them in large numbers.
Composers of the Renaissance period who wrote for four-course guitar include Alonso Mudarra, Miguel de Fuenllana, Adrian Le Roy, Grégoire Brayssing [fr], Guillaume de Morlaye, and Simon Gorlier [fr].
Four-course guitar
Some well known composers of the Baroque guitar were Gaspar Sanz, Robert de Visée, Francesco Corbetta and Santiago de Murcia.
From approximately 1780 to 1850, the guitar had numerous composers and performers including:
Hector Berlioz studied the guitar as a teenager; Franz Schubert owned at least two and wrote for the instrument; and Ludwig van Beethoven, after hearing Giuliani play, commented the instrument was "a miniature orchestra in itself". Niccolò Paganini was also a guitar virtuoso and composer. He once wrote: "I love the guitar for its harmony; it is my constant companion in all my travels". He also said, on another occasion: "I do not like this instrument, but regard it simply as a way of helping me to think."
The guitarist and composer Francisco Tárrega (November 21, 1852 – December 15, 1909) was one of the great guitar virtuosos and teachers and is considered the father of modern classical guitar playing. As a professor of guitar at the conservatories of Madrid and Barcelona, he defined many elements of the modern classical technique and elevated the importance of the guitar in the classical music tradition.
At the beginning of the 1920s, Andrés Segovia popularized the guitar with tours and early phonograph recordings. Segovia collaborated with the composers Federico Moreno Torroba and Joaquín Turina with the aim of extending the guitar repertoire with new music. Segovia's tour of South America revitalized public interest in the guitar and helped the guitar music of Manuel Ponce and Heitor Villa-Lobos reach a wider audience. The composers Alexandre Tansman and Mario Castelnuovo-Tedesco were commissioned by Segovia to write new pieces for the guitar. Luiz Bonfá popularized Brazilian musical styles such as the newly created Bossa Nova, which was well received by audiences in the USA.
The classical guitar repertoire also includes modern contemporary works – sometimes termed "New Music" – such as Elliott Carter's Changes, Cristóbal Halffter's Codex I, Luciano Berio's Sequenza XI, Maurizio Pisati's Sette Studi, Maurice Ohana's Si Le Jour Paraît, Sylvano Bussotti's Rara (eco sierologico), Ernst Krenek's Suite für Guitarre allein, Op. 164, Franco Donatoni's Algo: Due pezzi per chitarra, Paolo Coggiola's Variazioni Notturne, etc.
Performers who are known for including modern repertoire include Jürgen Ruck, Elena Càsoli, Leo Brouwer (when he was still performing), John Schneider, Reinbert Evers, Maria Kämmerling, Siegfried Behrend, David Starobin, Mats Scheidegger, Magnus Andersson, etc.
This type of repertoire is usually performed by guitarists who have particularly chosen to focus on the avant-garde in their performances.
Within the contemporary music scene itself, there are also works which are generally regarded as extreme. These include works such as Brian Ferneyhough's Kurze Schatten II, Sven-David Sandström's away from and Rolf Riehm's Toccata Orpheus etc. which are notorious for their extreme difficulty.
There are also a variety of databases documenting modern guitar works such as Sheer Pluck and others.
The evolution of the classical guitar and its repertoire spans more than four centuries. It has a history that was shaped by contributions from earlier instruments, such as the lute, the vihuela, and the baroque guitar.
The last guitarist to follow in Segovia's footsteps was Julian Bream and Julian Bream will be 73 years old on July 15th 2006. Miguel Llobet, Andrés Segovia and Julian Bream are the three performer personalities of the 20th century. Do not understand me wrong, we have many guitarists today that are very excellent performers, but none with such a distinct personality in their tone and style as Llobet, Segovia and Bream. In all instrumental areas, not just the guitar, there is a lack of individualism with a strong tendency to conformity. This I find very unfortunate since art (music, theatre or the pictorial arts) is a very individual and personal matter.
The origins of the modern guitar are not known with certainty. Some believe it is indigenous to Europe, while others think it is an imported instrument. Guitar-like instruments appear in ancient carvings and statues recovered from Egyptian, Sumerian, and Babylonian civilizations. This means that contemporary Iranian instruments such as the tanbur and setar are distantly related to the European guitar, as they all derive ultimately from the same ancient origins, but by very different historical routes and influences. The time where the most changes were made to the guitar was in the 1500s to the 1800s but during the late Middle Ages, gitterns called "guitars" were in use, but their construction and tuning were different from modern guitars. The guitarra latina in Spain had curved sides and a single hole. The guitarra morisca, which appears to have had Moorish influences, had an oval soundbox and many sound holes on its soundboard. By the 15th century, a four-course double-string instrument called the vihuela de mano, which was tuned like the later modern guitar except on one string and similar construction, first appeared in Spain and spread to France and Italy. In the 16th century, a fifth double-string was added. During this time, composers wrote mostly in tablature notation. In the middle of the 16th century, influences from the vihuela and the Renaissance guitar were combined and the baroque five-string guitar appeared in Spain. The baroque guitar quickly superseded the vihuela in popularity in Spain, France and Italy and Italian players and composers became prominent. In the late 18th century the six-string guitar quickly became popular at the expense of the five-string guitars. During the 19th century, the Spanish luthier and player Antonio de Torres gave the modern classical guitar its definitive form, with a broadened body, increased waist curve, thinned belly, and improved internal bracing. The modern classical guitar replaced an older form for the accompaniment of song and dance called flamenco, and a modified version, known as the flamenco guitar, was created.
Alonso de Mudarra's book Tres Libros de Música, published in Spain in 1546, contains the earliest known written pieces for a four-course guitarra. This four-course "guitar" was popular in France, Spain, and Italy. In France this instrument gained popularity among aristocrats. A considerable volume of music was published in Paris from the 1550s to the 1570s: Simon Gorlier's Le Troysième Livre... mis en tablature de Guiterne was published in 1551. In 1551 Adrian Le Roy also published his Premier Livre de Tablature de Guiterne, and in the same year he also published Briefve et facile instruction pour apprendre la tablature a bien accorder, conduire, et disposer la main sur la Guiterne. Robert Ballard, Grégoire Brayssing from Augsburg, and Guillaume Morlaye (c. 1510 – c. 1558) significantly contributed to its repertoire. Morlaye's Le Premier Livre de Chansons, Gaillardes, Pavannes, Bransles, Almandes, Fantasies – which has a four-course instrument illustrated on its title page – was published in partnership with Michel Fedenzat, and among other music, they published six books of tablature by lutenist Albert de Rippe (who was very likely Guillaume's teacher).
The written history of the classical guitar can be traced back to the early 16th century with the development of the vihuela in Spain. While the lute was then becoming popular in other parts of Europe, the Spaniards did not take to it well because of its association with the Moors. Instead, the lute-like vihuela appeared with two more strings that gave it more range and complexity. In its most developed form, the vihuela was a guitar-like instrument with six double strings made of gut, tuned like a modern classical guitar with the exception of the third string, which was tuned half a step lower. It has a high sound and is rather large to hold. Few have survived and most of what is known today come from diagrams and paintings.
The earliest extant six-string guitar is believed to have been built in 1779 by Gaetano Vinaccia (1759 – after 1831) in Naples, Italy; however, the date on the label is a little ambiguous. The Vinaccia family of luthiers is known for developing the mandolin. This guitar has been examined and does not show tell-tale signs of modifications from a double-course guitar. The authenticity of guitars allegedly produced before the 1790s is often in question. This also corresponds to when Moretti's 6-string method appeared, in 1792.
The modern classical guitar was developed in the 19th century by Antonio de Torres Jurado, Ignacio Fleta, Hermann Hauser Sr., and Robert Bouchet. Earlier similar instruments include the Spanish vihuela and gittern of the 15th and 16th century. Those instruments evolved into the 17th and 18th-century baroque guitar—and by the mid-19th century, early forms of the modern classical guitar.
The fingerstyle is used fervently on the modern classical guitar. The thumb traditionally plucks the bass – or root note – whereas the fingers ring the melody and its accompanying parts. Often classical guitar technique involves the use of the nails of the right hand to pluck the notes. Noted players were: Francisco Tárrega, Emilio Pujol, Andrés Segovia, Julian Bream, Agustín Barrios, and John Williams (guitarist).
The modern classical guitar is usually played in a seated position, with the instrument resting on the left lap – and the left foot placed on a footstool. Alternatively – if a footstool is not used – a guitar support can be placed between the guitar and the left lap (the support usually attaches to the instrument's side with suction cups). (There are of course exceptions, with some performers choosing to hold the instrument another way.)
Right-handed players use the fingers of the right hand to pluck the strings, with the thumb plucking from the top of a string downwards (downstroke) and the other fingers plucking from the bottom of the string upwards (upstroke). The little finger in classical technique as it evolved in the 20th century is used only to ride along with the ring finger without striking the strings and to thus physiologically facilitate the ring finger's motion.
In contrast, Flamenco technique, and classical compositions evoking Flamenco, employ the little finger semi-independently in the Flamenco four-finger rasgueado, that rapid strumming of the string by the fingers in reverse order employing the back of the fingernail—a familiar characteristic of Flamenco.
Flamenco technique, in the performance of the rasgueado also uses the upstroke of the four fingers and the downstroke of the thumb: the string is hit not only with the inner, fleshy side of the fingertip but also with the outer, fingernail side. This was also used in a technique of the vihuela called dedillo which has recently begun to be introduced on the classical guitar.
Some modern guitarists, such as Štěpán Rak and Kazuhito Yamashita, use the little finger independently, compensating for the little finger's shortness by maintaining an extremely long fingernail. Rak and Yamashita have also generalized the use of the upstroke of the four fingers and the downstroke of the thumb (the same technique as in the rasgueado of the Flamenco: as explained above the string is hit not only with the inner, fleshy side of the fingertip but also with the outer, fingernail side) both as a free stroke and as a rest stroke.
As with other plucked instruments (such as the lute), the musician directly touches the strings (usually plucking) to produce the sound. This has important consequences: Different tone/timbre (of a single note) can be produced by plucking the string in different manners (apoyando or tirando) and in different positions (such as closer and further away from the guitar bridge). For example, plucking an open string will sound brighter than playing the same note(s) on a fretted position (which would have a warmer tone).
The instrument's versatility means it can create a variety of tones, but this finger-picking style also makes the instrument harder to learn than a standard acoustic guitar's strumming technique.
In guitar scores the five fingers of the right-hand (which pluck the strings) are designated by the first letter of their Spanish names namely p = thumb (pulgar), i = index finger (índice), m = middle finger (mayor), a = ring finger (anular), c = little finger or pinky (meñique/chiquito)
The four fingers of the left hand (which fret the strings) are designated 1 = index, 2 = major, 3 = ring finger, 4 = little finger. 0 designates an open string—a string not stopped by a finger and whose full length thus vibrates when plucked. It is rare to use the left hand thumb in performance, the neck of a classical guitar being too wide for comfort, and normal technique keeps the thumb behind the neck. However Johann Kaspar Mertz, for example, is notable for specifying the thumb to fret bass notes on the sixth string, notated with an up arrowhead (⌃).
Scores (contrary to tablatures) do not systematically indicate the string to pluck (though the choice is usually obvious). When indicating the string is useful, the score uses the numbers 1 to 6 inside circles (highest-pitch sting to lowest).
Scores do not systematically indicate fretboard positions (where to put the first finger of the fretting hand), but when helpful (mostly with barrés chords) the score indicates positions with Roman numerals from the first position I (index finger on the 1st fret: F-B flat-E flat-A flat-C-F) to the twelfth position XII (index finger on the 12th fret: E-A-D-G-B-E. The 12th fret is where the body begins) or even higher up to position XIX (the classical guitar most often having 19 frets, with the 19th fret being most often split and not being usable to fret the 3rd and 4th strings).
To achieve tremolo effects and rapid, fluent scale passages, the player must practice alternation, that is, never plucking a string with the same finger twice in a row. Using p to indicate the thumb, i the index finger, m the middle finger and a the ring finger, common alternation patterns include:
Music written specifically for the classical guitar dates from the addition of the sixth string (the baroque guitar normally had five pairs of strings) in the late 18th century.
A guitar recital may include a variety of works, e.g., works written originally for the lute or vihuela by composers such as John Dowland (b. England 1563) and Luis de Narváez (b. Spain c. 1500), and also music written for the harpsichord by Domenico Scarlatti (b. Italy 1685), for the baroque lute by Sylvius Leopold Weiss (b. Germany 1687), for the baroque guitar by Robert de Visée (b. France c. 1650) or even Spanish-flavored music written for the piano by Isaac Albéniz (b. Spain 1860) and Enrique Granados (b. Spain 1867). The most important composer who did not write for the guitar but whose music is often played on it is Johann Sebastian Bach (b. Germany 1685), whose baroque lute works have proved highly adaptable to the instrument.
Of music written originally for guitar, the earliest important composers are from the classical period and include Fernando Sor (b. Spain 1778) and Mauro Giuliani (b. Italy 1781), both of whom wrote in a style strongly influenced by Viennese classicism. In the 19th-century guitar composers such as Johann Kaspar Mertz (b. Slovakia, Austria 1806) were strongly influenced by the dominance of the piano. Not until the end of the nineteenth century did the guitar begin to establish its own unique identity. Francisco Tárrega (b. Spain 1852) was central to this, sometimes incorporating stylized aspects of flamenco's Moorish influences into his romantic miniatures. This was part of late 19th century mainstream European musical nationalism. Albéniz and Granados were central to this movement; their evocation of the guitar was so successful that their compositions have been absorbed into the standard guitar repertoire.
The steel-string and electric guitars characteristic to the rise of rock and roll in the post-WWII era became more widely played in North America and the English-speaking world. Agustín Barrios Mangoré of Paraguay composed many works and brought into the mainstream the characteristics of Latin American music, as did the Brazilian composer Heitor Villa-Lobos. Andrés Segovia commissioned works from Spanish composers such as Federico Moreno Torroba and Joaquín Rodrigo, Italians such as Mario Castelnuovo-Tedesco and Latin American composers such as Manuel Ponce of Mexico. Other prominent Latin American composers are Leo Brouwer of Cuba, Antonio Lauro of Venezuela and Enrique Solares of Guatemala. Julian Bream of Britain managed to get nearly every British composer from William Walton and Benjamin Britten to Peter Maxwell Davies to write significant works for guitar. Bream's collaborations with tenor Peter Pears also resulted in song cycles by Britten, Lennox Berkeley and others. There are significant works by composers such as Hans Werner Henze of Germany, Gilbert Biberian of England and Roland Chadwick of Australia.
The classical guitar also became widely used in popular music and rock & roll in the 1960s after guitarist Mason Williams popularized the instrument in his instrumental hit Classical Gas. Guitarist Christopher Parkening is quoted in the book Classical Gas: The Music of Mason Williams as saying that it is the most requested guitar piece besides Malagueña and perhaps the best-known instrumental guitar piece today. In the field of New Flamenco, the works and performances of Spanish composer and player Paco de Lucía are known worldwide.
Not many classical guitar concertos were written through history. Nevertheless, some guitar concertos are nowadays widely known and popular, especially Joaquín Rodrigo's Concierto de Aranjuez (with the famous theme from 2nd movement) and Fantasía para un gentilhombre. Composers, who also wrote famous guitar concertos are: Antonio Vivaldi (originally for mandolin or lute), Mauro Giuliani, Heitor Villa-Lobos, Mario Castelnuovo-Tedesco, Manuel Ponce, Leo Brouwer, Lennox Berkeley and Malcolm Arnold. Nowadays, more and more contemporary composers decide to write a guitar concerto, among them Bosco Sacro by Federico Biscione, for guitar and string orchestra, is one of the most inspired.
The classical guitar is distinguished by a number of characteristics:
Parts of typical classical guitars include:
The fretboard (also called the fingerboard) is a piece of wood embedded with metal frets that constitutes the top of the neck. It is flat or slightly curved. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which the fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Fretboards are most commonly made of ebony, but may also be made of rosewood, some other hardwood, or of phenolic composite ("micarta").
Frets are the metal strips (usually nickel alloy or stainless steel) embedded along the fingerboard and placed at points that divide the length of string mathematically. The strings' vibrating length is determined when the strings are pressed down behind the frets. Each fret produces a different pitch and each pitch spaced a half-step apart on the 12 tone scale. The ratio of the widths of two consecutive frets is the twelfth root of two ( 2 12 {\displaystyle {\sqrt[{12}]{2}}} ), whose numeric value is about 1.059463. The twelfth fret divides the string into two exact halves and the 24th fret (if present) divides the string in half yet again. Every twelve frets represents one octave. This arrangement of frets results in equal tempered tuning.
A classical guitar's frets, fretboard, tuners, headstock, all attached to a long wooden extension, collectively constitute its neck. The wood for the fretboard usually differs from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used. The most common scale length for classical guitar is 650mm (calculated by measuring the distance between the end of the nut and the center of the 12th fret, then doubling that measurement). However, scale lengths may vary from 635-664mm or more.
This is the point where the neck meets the body. In the traditional Spanish neck joint, the neck and block are one piece with the sides inserted into slots cut in the block. Other necks are built separately and joined to the body either with a dovetail joint, mortise or flush joint. These joints are usually glued and can be reinforced with mechanical fasteners. Recently many manufacturers use bolt-on fasteners. Bolt-on neck joints were once associated only with less expensive instruments but now some top manufacturers and hand builders are using variations of this method. Some people believed that the Spanish-style one piece neck/block and glued dovetail necks have better sustain, but testing has failed to confirm this. While most traditional Spanish style builders use the one-piece neck/heel block, Fleta, a prominent Spanish builder, used a dovetail joint due to the influence of his early training in violin making. One reason for the introduction of mechanical joints was to make it easier to repair necks. This is more of a problem with steel string guitars than with nylon strings, which have about half the string tension. This is why nylon string guitars often do not include a truss rod either.
The body of the instrument is a major determinant of the overall sound variety for acoustic guitars. The guitar top, or soundboard, is a finely crafted and engineered element often made of spruce or red cedar. Considered the most prominent factor in determining the sound quality of a guitar, this thin (often 2 or 3 mm thick) piece of wood has a uniform thickness and is strengthened by different types of internal bracing. The back is made in rosewood and Brazilian rosewood is especially coveted, but mahogany or other decorative woods are sometimes used.
The majority of the sound is caused by the vibration of the guitar top as the energy of the vibrating strings is transferred to it. Different patterns of wood bracing have been used through the years by luthiers (Torres, Hauser, Ramírez, Fleta, and C.F. Martin being among the most influential designers of their times); to not only strengthen the top against collapsing under the tremendous stress exerted by the tensioned strings, but also to affect the resonance of the top. Some contemporary guitar makers have introduced new construction concepts such as "double-top" consisting of two extra-thin wooden plates separated by Nomex, or carbon-fiber reinforced lattice – pattern bracing. The back and sides are made out of a variety of woods such as mahogany, maple, cypress Indian rosewood and highly regarded Brazilian rosewood (Dalbergia nigra). Each one is chosen for its aesthetic effect and structural strength, and such choice can also play a role in determining the instrument's timbre. These are also strengthened with internal bracing, and decorated with inlays and purfling. Antonio de Torres Jurado proved that it was the top, and not the back and sides of the guitar that gave the instrument its sound, in 1862 he built a guitar with back and sides of papier-mâché. (This guitar resides in the Museu de la Musica in Barcelona, and before the year 2000 it was restored to playable condition by the brothers Yagüe, Barcelona). The body of a classical guitar is a resonating chamber that projects the vibrations of the body through a sound hole, allowing the acoustic guitar to be heard without amplification. The sound hole is normally a single round hole in the top of the guitar (under the strings), though some have different placement, shapes, or numbers of holes. How much air an instrument can move determines its maximum volume.
The top, back and sides of a classical guitar body are very thin, so a flexible piece of wood called kerfing (because it is often scored, or kerfed so it bends with the shape of the rim) is glued into the corners where the rim meets the top and back. This interior reinforcement provides 5 to 20 mm of solid gluing area for these corner joints.
During final construction, a small section of the outside corners is carved or routed out and filled with binding material on the outside corners and decorative strips of material next to the binding, which are called purfling. This binding serves to seal off the endgrain of the top and back. Binding and purfling materials are generally made of either wood or high-quality plastic materials.
The main purpose of the bridge on a classical guitar is to transfer the vibration from the strings to the soundboard, which vibrates the air inside of the guitar, thereby amplifying the sound produced by the strings. The bridge holds the strings in place on the body. Also, the position of the saddle, usually a strip of bone or plastic that supports the strings off the bridge, determines the distance to the nut (at the top of the fingerboard).
The modern full-size classical guitar has a scale length of around 650 mm (25.6 in), with an overall instrument length of 965–1,016 mm (38.0–40.0 in). The scale length has remained quite consistent since it was chosen by the originator of the instrument, Antonio de Torres. This length may have been chosen because it's twice the length of a violin string. As the guitar is tuned to one octave below that of the violin, the same size gut could be used for the first strings of both instruments.
Smaller-scale instruments are produced to assist children in learning the instrument as the smaller scale leads to the frets being closer together, making it easier for smaller hands. The scale-size for the smaller guitars is usually in the range 484–578 mm (19.1–22.8 in), with an instrument length of 785–915 mm (30.9–36.0 in). Full-size instruments are sometimes referred to as 4/4, while the smaller sizes are 3/4, 1/2 or 1/4.
A variety of different tunings are used. The most common by far, which one could call the "standard tuning" is:
The above order is the tuning from the 1st string (highest-pitched string e'—spatially the bottom string in playing position) to the 6th string – lowest-pitched string E—spatially the upper string in playing position, and hence comfortable to pluck with the thumb.
The explanation for this "asymmetrical" tuning (in the sense that the maj 3rd is not between the two middle strings, as in the tuning of the viola da gamba) is probably that the guitar originated as a 4-string instrument (actually an instrument with 4 double courses of strings, see above) with a maj 3rd between the 2nd and 3rd strings, and it only became a 6-string instrument by gradual addition of a 5th string and then a 6th string tuned a 4th apart:
"The development of the modern tuning can be traced in stages. One of the tunings from the 16th century is C-F-A-D. This is equivalent to the top four strings of the modern guitar tuned a tone lower. However, the absolute pitch for these notes is not equivalent to modern "concert pitch". The tuning of the four-course guitar was moved up by a tone and toward the end of the 16th century, five-course instruments were in use with an added lower string tuned to A. This produced A-D-G-B-E, one of a wide number of variant tunings of the period. The low E string was added during the 18th century."
This tuning is such that neighboring strings are at most 5 semitones apart. There are also a variety of commonly used alternate tunings. The most common is known as Drop D tuning which has the 6th string tuned down from an E to a D. | [

"text": "The origins of the modern guitar are not known with certainty. Some believe it is indigenous to Europe, while others think it is an imported instrument. Guitar-like instruments appear in ancient carvings and statues recovered from Egyptian, Sumerian, and Babylonian civilizations. This means that contemporary Iranian instruments such as the tanbur and setar are distantly related to the European guitar, as they all derive ultimately from the same ancient origins, but by very different historical routes and influences. The time where the most changes were made to the guitar was in the 1500s to the 1800s but during the late Middle Ages, gitterns called \"guitars\" were in use, but their construction and tuning were different from modern guitars. The guitarra latina in Spain had curved sides and a single hole. The guitarra morisca, which appears to have had Moorish influences, had an oval soundbox and many sound holes on its soundboard. By the 15th century, a four-course double-string instrument called the vihuela de mano, which was tuned like the later modern guitar except on one string and similar construction, first appeared in Spain and spread to France and Italy. In the 16th century, a fifth double-string was added. During this time, composers wrote mostly in tablature notation. In the middle of the 16th century, influences from the vihuela and the Renaissance guitar were combined and the baroque five-string guitar appeared in Spain. The baroque guitar quickly superseded the vihuela in popularity in Spain, France and Italy and Italian players and composers became prominent. In the late 18th century the six-string guitar quickly became popular at the expense of the five-string guitars. During the 19th century, the Spanish luthier and player Antonio de Torres gave the modern classical guitar its definitive form, with a broadened body, increased waist curve, thinned belly, and improved internal bracing. The modern classical guitar replaced an older form for the accompaniment of song and dance called flamenco, and a modified version, known as the flamenco guitar, was created.",

A considerable volume of music was published in Paris from the 1550s to the 1570s: Simon Gorlier's Le Troysième Livre... mis en tablature de Guiterne was published in 1551.

Recently many manufacturers use bolt-on fasteners.

Some people believed that the Spanish-style one piece neck/block and glued dovetail necks have better sustain, but testing has failed to confirm this. While most traditional Spanish style builders use the one-piece neck/heel block, Fleta, a prominent Spanish builder, used a dovetail joint due to the influence of his early training in violin making.

Martin being among the most influential designers of their times); to not only strengthen the top against collapsing under the tremendous stress exerted by the tensioned strings, but also to affect the resonance of the top. Some contemporary guitar makers have introduced new construction concepts such as \"double-top\" consisting of two extra-thin wooden plates separated by Nomex, or carbon-fiber reinforced lattice – pattern bracing. The back and sides are made out of a variety of woods such as mahogany, maple, cypress Indian rosewood and highly regarded Brazilian rosewood (Dalbergia nigra). Each one is chosen for its aesthetic effect and structural strength, and such choice can also play a role in determining the instrument's timbre. These are also strengthened with internal bracing, and decorated with inlays and purfling. Antonio de Torres Jurado proved that it was the top, and not the back and sides of the guitar that gave the instrument its sound, in 1862 he built a guitar with back and sides of papier-mâché. (This guitar resides in the Museu de la Musica in Barcelona, and before the year 2000 it was restored to playable condition by the brothers Yagüe, Barcelona). The body of a classical guitar is a resonating chamber that projects the vibrations of the body through a sound hole, allowing the acoustic guitar to be heard without amplification.

An acoustic wooden string instrument with strings made of gut or nylon, it is a precursor of the modern steel-string acoustic and electric guitars, both of which use metal strings. Classical guitars derive from the Spanish vihuela and gittern of the 15th and 16th century. Those instruments evolved into the 17th and 18th-century baroque guitar—and by the mid-19th century, early forms of the modern classical guitar. Today's modern classical guitar was established by the late designs of the 19th-century Spanish luthier, Antonio Torres Jurado. For a right-handed player, the traditional classical guitar has 12 frets clear of the body and is properly held up by the left leg, so that the hand that plucks or strums the strings does so near the back of the sound hole. However, the right-hand may move closer to the fretboard to achieve different tonal qualities. The player typically holds the left leg higher by the use of a foot rest. The modern steel string guitar, on the other hand, usually has 14 frets clear of the body and is commonly held with a strap around the neck and shoulder. The phrase "classical guitar" may refer to either of two concepts other than the instrument itself: The instrumental finger technique common to classical guitar—individual strings plucked with the fingernails or, less frequently, fingertips
The instrument's classical music repertoire The term modern classical guitar sometimes distinguishes the classical guitar from older forms of guitar, which are in their broadest sense also called classical, or more specifically, early guitars. Examples of early guitars include the six-string early romantic guitar, and the earlier baroque guitars with five courses. The materials and the methods of classical guitar construction may vary, but the typical shape is either modern classical guitar or that historic classical guitar similar to the early romantic guitars of France and Italy. Classical guitar strings once made of gut are now made of materials such as nylon or fluoropolymers, typically with silver-plated copper fine wire wound about the acoustically lower strings. A guitar family tree may be identified. The flamenco guitar derives from the modern classical, but has differences in material, construction and sound. | 2001-10-05T01:21:39Z | 2023-12-12T06:00:01Z | [

5,813 | C. S. Lewis | Clive Staples Lewis FBA (29 November 1898 – 22 November 1963) was a British writer, literary scholar, and Anglican lay theologian. He held academic positions in English literature at both Magdalen College, Oxford (1925–1954), and Magdalene College, Cambridge (1954–1963). He is best known as the author of The Chronicles of Narnia, but he is also noted for his other works of fiction, such as The Screwtape Letters and The Space Trilogy, and for his non-fiction Christian apologetics, including Mere Christianity, Miracles, and The Problem of Pain.
Lewis was a close friend of J. R. R. Tolkien, author of The Lord of the Rings. Both men served on the English faculty at Oxford University and were active in the informal Oxford literary group known as the Inklings. According to Lewis's 1955 memoir Surprised by Joy, he was baptized in the Church of Ireland but fell away from his faith during adolescence. Lewis returned to Anglicanism at the age of 32, owing to the influence of Tolkien and other friends, and he became an "ordinary layman of the Church of England". Lewis's faith profoundly affected his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
Lewis wrote more than 30 books which have been translated into more than 30 languages and have sold millions of copies. The books that make up The Chronicles of Narnia have sold the most and have been popularized on stage, TV, radio, and cinema. His philosophical writings are widely cited by Christian scholars from many denominations.
In 1956, Lewis married American writer Joy Davidman; she died of cancer four years later at the age of 45. Lewis died on 22 November 1963 from kidney failure, one week before his 65th birthday. In 2013, on the 50th anniversary of his death, Lewis was honoured with a memorial in Poets' Corner in Westminster Abbey.
Clive Staples Lewis was born in Belfast in Ulster, Ireland (before partition), on 29 November 1898. His father was Albert James Lewis (1863–1929), a solicitor whose father Richard Lewis had come to Ireland from Wales during the mid-19th century. Lewis's mother was Florence Augusta Lewis née Hamilton (1862–1908), known as Flora, the daughter of Thomas Hamilton, a Church of Ireland priest, and the great-granddaughter of both Bishop Hugh Hamilton and John Staples. Lewis had an elder brother, Warren Hamilton Lewis (known as "Warnie"). He was baptized on 29 January 1899 by his maternal grandfather in St Mark's Church, Dundela.
When his dog Jacksie was killed by a car, the four-year old Lewis adopted the name Jacksie. At first, he would answer to no other name, but later accepted Jack, the name by which he was known to friends and family for the rest of his life. When he was seven, his family moved into "Little Lea", the family home of his childhood, in the Strandtown area of East Belfast.
As a boy, Lewis was fascinated with anthropomorphic animals; he fell in love with Beatrix Potter's stories and often wrote and illustrated his own animal tales. Along with his brother Warnie, he created the world of Boxen, a fantasy land inhabited and run by animals. Lewis loved to read from an early age. His father's house was filled with books; he later wrote that finding something to read was as easy as walking into a field and "finding a new blade of grass".
The New House is almost a major character in my story. I am the product of long corridors, empty sunlit rooms, upstair indoor silences, attics explored in solitude, distant noises of gurgling cisterns and pipes, and the noise of wind under the tiles. Also, of endless books.
—Surprised by Joy
Lewis was schooled by private tutors until age nine, when his mother died in 1908 from cancer. His father then sent him to England to live and study at Wynyard School in Watford, Hertfordshire. Lewis's brother had enrolled there three years previously. Not long after, the school was closed due to a lack of pupils. Lewis then attended Campbell College in the east of Belfast about a mile from his home, but left after a few months due to respiratory problems.
He was then sent back to England to the health-resort town of Malvern, Worcestershire, where he attended the preparatory school Cherbourg House, which Lewis referred to as "Chartres" in his autobiography. It was during this time that he abandoned the Christianity he was taught as a child and became an atheist. During this time he also developed a fascination with European mythology and the occult.
In September 1913, Lewis enrolled at Malvern College, where he remained until the following June. He found the school socially competitive. After leaving Malvern, he studied privately with William T. Kirkpatrick, his father's old tutor and former headmaster of Lurgan College.
As a teenager, Lewis was wonderstruck by the songs and legends of what he called Northernness, the ancient literature of Scandinavia preserved in the Icelandic sagas. These legends intensified an inner longing that he would later call "joy". He also grew to love nature; its beauty reminded him of the stories of the North, and the stories of the North reminded him of the beauties of nature. His teenage writings moved away from the tales of Boxen, and he began experimenting with different art forms such as epic poetry and opera to try to capture his new-found interest in Norse mythology and the natural world.
Studying with Kirkpatrick ("The Great Knock", as Lewis afterward called him) instilled in him a love of Greek literature and mythology and sharpened his debate and reasoning skills. In 1916, Lewis was awarded a scholarship at University College, Oxford.
Lewis experienced a certain cultural shock on first arriving in England: "No Englishman will be able to understand my first impressions of England," Lewis wrote in Surprised by Joy. "The strange English accents with which I was surrounded seemed like the voices of demons. But what was worst was the English landscape ... I have made up the quarrel since; but at that moment I conceived a hatred for England which took many years to heal."
From boyhood, Lewis had immersed himself in Norse and Greek mythology, and later in Irish mythology and literature. He also expressed an interest in the Irish language, though there is not much evidence that he laboured to learn it. He developed a particular fondness for W. B. Yeats, in part because of Yeats's use of Ireland's Celtic heritage in poetry. In a letter to a friend, Lewis wrote, "I have here discovered an author exactly after my own heart, whom I am sure you would delight in, W. B. Yeats. He writes plays and poems of rare spirit and beauty about our old Irish mythology."
In 1921, Lewis met Yeats twice, since Yeats had moved to Oxford. Lewis was surprised to find his English peers indifferent to Yeats and the Celtic Revival movement, and wrote: "I am often surprised to find how utterly ignored Yeats is among the men I have met: perhaps his appeal is purely Irish – if so, then thank the gods that I am Irish." Early in his career, Lewis considered sending his work to the major Dublin publishers, writing: "If I do ever send my stuff to a publisher, I think I shall try Maunsel, those Dublin people, and so tack myself definitely onto the Irish school."
After his conversion to Christianity, his interests gravitated towards Christian theology and away from pagan Celtic mysticism (as opposed to Celtic Christian mysticism).
Lewis occasionally expressed a somewhat tongue-in-cheek chauvinism towards the English. Describing an encounter with a fellow Irishman, he wrote: "Like all Irish people who meet in England, we ended by criticisms on the invincible flippancy and dullness of the Anglo-Saxon race. After all, there is no doubt, ami, that the Irish are the only people: with all their faults, I would not gladly live or die among another folk." Throughout his life, he sought out the company of other Irish people living in England and visited Northern Ireland regularly. In 1958 he spent his honeymoon there at the Old Inn, Crawfordsburn, which he called "my Irish life".
Various critics have suggested that it was Lewis's dismay over the sectarian conflict in his native Belfast which led him to eventually adopt such an ecumenical brand of Christianity. As one critic has said, Lewis "repeatedly extolled the virtues of all branches of the Christian faith, emphasising a need for unity among Christians around what the Catholic writer G. K. Chesterton called 'Mere Christianity', the core doctrinal beliefs that all denominations share". On the other hand, Paul Stevens of the University of Toronto has written that "Lewis' mere Christianity masked many of the political prejudices of an old-fashioned Ulster Protestant, a native of middle-class Belfast for whom British withdrawal from Northern Ireland even in the 1950s and 1960s was unthinkable."
Lewis entered Oxford in the 1917 summer term, studying at University College, and shortly after, he joined the Officers' Training Corps at the university as his "most promising route into the army". From there, he was drafted into a Cadet Battalion for training. After his training, he was commissioned into the 3rd Battalion of the Somerset Light Infantry of the British Army as a Second Lieutenant, and was later transferred to the 1st Battalion of the regiment, then serving in France (he would not remain with the 3rd Battalion as it moved to Northern Ireland). Within months of entering Oxford, he was shipped by the British Army to France to fight in the First World War.
On his 19th birthday (29 November 1917), Lewis arrived at the front line in the Somme Valley in France, where he experienced trench warfare for the first time. On 15 April 1918, as 1st Battalion, Somerset Light Infantry assaulted the village of Riez du Vinage in the midst of the German spring offensive, Lewis was wounded and two of his colleagues were killed by a British shell falling short of its target. He was depressed and homesick during his convalescence and, upon his recovery in October, he was assigned to duty in Andover, England. He was demobilized in December 1918 and soon restarted his studies. In a later letter, Lewis stated that his experience of the horrors of war, along with the loss of his mother and unhappiness in school, were the basis of his pessimism and atheism.
After Lewis returned to Oxford University, he received a First in Honour Moderations (Greek and Latin literature) in 1920, a First in Greats (Philosophy and Ancient History) in 1922, and a First in English in 1923. In 1924 he became a Philosophy tutor at University College and, in 1925, was elected a Fellow and Tutor in English Literature at Magdalen College, where he served for 29 years until 1954.
During his army training, Lewis shared a room with another cadet, Edward Courtnay Francis "Paddy" Moore (1898–1918). Maureen Moore, Paddy's sister, said that the two made a mutual pact that if either died during the war, the survivor would take care of both of their families. Paddy was killed in action in 1918 and Lewis kept his promise. Paddy had earlier introduced Lewis to his mother, Janie King Moore, and a friendship quickly sprang up between Lewis, who was 18 when they met, and Janie, who was 45. The friendship with Moore was particularly important to Lewis while he was recovering from his wounds in hospital, as his father did not visit him.
Lewis lived with and cared for Moore until she was hospitalized in the late 1940s. He routinely introduced her as his mother, referred to her as such in letters, and developed a deeply affectionate friendship with her. Lewis's own mother had died when he was a child, while his father was distant, demanding, and eccentric.
Speculation regarding their relationship resurfaced with the 1990 publication of A. N. Wilson's biography of Lewis. Wilson (who never met Lewis) attempted to make a case for their having been lovers for a time. Wilson's biography was not the first to address the question of Lewis's relationship with Moore. George Sayer knew Lewis for 29 years, and he had sought to shed light on the relationship during the period of 14 years before Lewis's conversion to Christianity. In his biography Jack: A Life of C. S. Lewis, he wrote:
Were they lovers? Owen Barfield, who knew Jack well in the 1920s, once said that he thought the likelihood was "fifty-fifty". Although she was twenty-six years older than Jack, she was still a handsome woman, and he was certainly infatuated with her. But it seems very odd, if they were lovers, that he would call her "mother". We know, too, that they did not share the same bedroom. It seems most likely that he was bound to her by the promise he had given to Paddy and that his promise was reinforced by his love for her as his second mother.
Later Sayer changed his mind. In the introduction to the 1997 edition of his biography of Lewis he wrote:
I have had to alter my opinion of Lewis's relationship with Mrs. Moore. In chapter eight of this book I wrote that I was uncertain about whether they were lovers. Now after conversations with Mrs. Moore's daughter, Maureen, and a consideration of the way in which their bedrooms were arranged at The Kilns, I am quite certain that they were.
However, the romantic nature of the relationship is doubted by other writers; for example, Philip Zaleski and Carol Zaleski write in The Fellowship that
When—or whether—Lewis commenced an affair with Mrs. Moore remains unclear.
Lewis spoke well of Mrs. Moore throughout his life, saying to his friend George Sayer, "She was generous and taught me to be generous, too." In December 1917, Lewis wrote in a letter to his childhood friend Arthur Greeves that Janie and Greeves were "the two people who matter most to me in the world".
In 1930, Lewis moved into The Kilns with his brother Warnie, Mrs. Moore, and her daughter Maureen. The Kilns was a house in the district of Headington Quarry on the outskirts of Oxford, now part of the suburb of Risinghurst. They all contributed financially to the purchase of the house, which eventually passed to Maureen, who by then was Dame Maureen Dunbar, when Warren died in 1973.
Moore had dementia in her later years and was eventually moved into a nursing home, where she died in 1951. Lewis visited her every day in this home until her death.
Lewis was raised in a religious family that attended the Church of Ireland. He became an atheist at age 15, though he later described his young self as being paradoxically "very angry with God for not existing" and "equally angry with him for creating a world". His early separation from Christianity began when he started to view his religion as a chore and a duty; around this time, he also gained an interest in the occult, as his studies expanded to include such topics. Lewis quoted Lucretius (De rerum natura, 5.198–9) as having one of the strongest arguments for atheism:
Nequaquam nobis divinitus esse paratam Naturam rerum; tanta stat praedita culpa
which he translated poetically as follows:
Had God designed the world, it would not be A world so frail and faulty as we see.
(This is a highly poetic, rather than a literal translation. A more literal translation, by William Ellery Leonard, reads: "That in no wise the nature of all things / For us was fashioned by a power divine – / So great the faults it stands encumbered with.")
Lewis's interest in the works of the Scottish writer George MacDonald was part of what turned him from atheism. This can be seen particularly well through this passage in Lewis's The Great Divorce, chapter nine, when the semi-autobiographical main character meets MacDonald in Heaven:
... I tried, trembling, to tell this man all that his writings had done for me. I tried to tell how a certain frosty afternoon at Leatherhead Station when I had first bought a copy of Phantastes (being then about sixteen years old) had been to me what the first sight of Beatrice had been to Dante: Here begins the new life. I started to confess how long that Life had delayed in the region of imagination merely: how slowly and reluctantly I had come to admit that his Christendom had more than an accidental connexion with it, how hard I had tried not to see the true name of the quality which first met me in his books is Holiness.
He eventually returned to Christianity, having been influenced by arguments with his Oxford colleague and friend J. R. R. Tolkien, whom he seems to have met for the first time on 11 May 1926, as well as the book The Everlasting Man by G. K. Chesterton. Lewis vigorously resisted conversion, noting that he was brought into Christianity like a prodigal, "kicking, struggling, resentful, and darting his eyes in every direction for a chance to escape". He described his last struggle in Surprised by Joy:
You must picture me alone in that room in Magdalen [College, Oxford], night after night, feeling, whenever my mind lifted even for a second from my work, the steady, unrelenting approach of Him whom I so earnestly desired not to meet. That which I greatly feared had at last come upon me. In the Trinity Term of 1929 I gave in, and admitted that God was God, and knelt and prayed: perhaps, that night, the most dejected and reluctant convert in all England.
After his conversion to theism in 1929, Lewis converted to Christianity in 1931, following a long discussion during a late-night walk along Addison's Walk with close friends Tolkien and Hugo Dyson. He records making a specific commitment to Christian belief while on his way to the zoo with his brother. He became a member of the Church of England – somewhat to the disappointment of Tolkien, who had hoped that he would join the Catholic Church.
Lewis was a committed Anglican who upheld a largely orthodox Anglican theology, though in his apologetic writings, he made an effort to avoid espousing any one denomination. In his later writings, some believe that he proposed ideas such as purification of venial sins after death in purgatory (The Great Divorce and Letters to Malcolm) and mortal sin (The Screwtape Letters), which are generally considered to be Roman Catholic teachings, although they are also widely held in Anglicanism (particularly in high church Anglo-Catholic circles). Regardless, Lewis considered himself an entirely orthodox Anglican to the end of his life, reflecting that he had initially attended church only to receive communion and had been repelled by the hymns and the poor quality of the sermons. He later came to consider himself honoured by worshipping with men of faith who came in shabby clothes and work boots and who sang all the verses to all the hymns.
After the outbreak of the Second World War in 1939, the Lewises took child evacuees from London and other cities into The Kilns. Lewis was only 40 when the war began, and he tried to re-enter military service, offering to instruct cadets; however, his offer was not accepted. He rejected the recruiting office's suggestion of writing columns for the Ministry of Information in the press, as he did not want to "write lies" to deceive the enemy. He later served in the local Home Guard in Oxford.
From 1941 to 1943, Lewis spoke on religious programmes broadcast by the BBC from London while the city was under periodic air raids. These broadcasts were appreciated by civilians and servicemen at that stage. For example, Air Chief Marshal Sir Donald Hardman wrote:
The youthful Alistair Cooke was less impressed, and in 1944 described "the alarming vogue of Mr. C.S. Lewis" as an example of how wartime tends to "spawn so many quack religions and Messiahs". The broadcasts were anthologized in Mere Christianity. From 1941, Lewis was occupied at his summer holiday weekends visiting R.A.F. stations to speak on his faith, invited by Chaplain-in-Chief Maurice Edwards.
It was also during the same wartime period that Lewis was invited to become first President of the Oxford Socratic Club in January 1942, a position that he enthusiastically held until he resigned on appointment to Cambridge University in 1954.
Lewis was named on the last list of honours by George VI in December 1951 as a Commander of the Order of the British Empire (CBE) but declined so as to avoid association with any political issues.
In 1954, Lewis accepted the newly founded chair in Mediaeval and Renaissance Literature at Magdalene College, Cambridge, where he finished his career. He maintained a strong attachment to the city of Oxford, keeping a home there and returning on weekends until his death in 1963.
She was my daughter and my mother, my pupil and my teacher, my subject and my sovereign; and always, holding all these in solution, my trusty comrade, friend, shipmate, fellow-soldier. My mistress; but at the same time all that any man friend (and I have good ones) has ever been to me. Perhaps more.
C. S. Lewis
In later life, Lewis corresponded with Joy Davidman Gresham, an American writer of Jewish background, a former Communist, and a convert from atheism to Christianity. She was separated from her alcoholic and abusive husband, novelist William L. Gresham, and came to England with her two sons, David and Douglas. Lewis at first regarded her as an agreeable intellectual companion and personal friend, and it was on this level that he agreed to enter into a civil marriage contract with her so that she could continue to live in the UK. They were married at the register office, 42 St Giles', Oxford, on 23 April 1956. Lewis's brother Warren wrote: "For Jack the attraction was at first undoubtedly intellectual. Joy was the only woman whom he had met ... who had a brain which matched his own in suppleness, in width of interest, and in analytical grasp, and above all in humour and a sense of fun." After complaining of a painful hip, she was diagnosed with terminal bone cancer, and the relationship developed to the point that they sought a Christian marriage. Since she was divorced, this was not straightforward in the Church of England at the time, but a friend, the Rev. Peter Bide, performed the ceremony at her bed in the Churchill Hospital on 21 March 1957.
Gresham's cancer soon went into remission, and the couple lived together as a family with Warren Lewis until 1960, when her cancer recurred. She died on 13 July 1960. Earlier that year, the couple took a brief holiday in Greece and the Aegean; Lewis was fond of walking but not of travel, and this marked his only crossing of the English Channel after 1918. Lewis's book A Grief Observed describes his experience of bereavement in such a raw and personal fashion that he originally released it under the pseudonym N. W. Clerk to keep readers from associating the book with him. Ironically, many friends recommended the book to Lewis as a method for dealing with his own grief. After Lewis's death, his authorship was made public by Faber's, with the permission of the executors.
Lewis continued to raise Gresham's two sons after her death. Douglas Gresham is a Christian like Lewis and his mother, while David Gresham turned to his mother's ancestral faith, becoming Orthodox Jewish in his beliefs. His mother's writings had featured the Jews in an unsympathetic manner, particularly on "shohet" (ritual slaughterer). David informed Lewis that he was going to become a ritual slaughterer to present this type of Jewish religious functionary to the world in a more favourable light. In a 2005 interview, Douglas Gresham acknowledged that he and his brother were not close, although they had corresponded via email.
David died on 25 December 2014. In 2020, Douglas revealed that his brother had died at a Swiss mental hospital, and that when David was a young man he had been diagnosed with paranoid schizophrenia.
In early June 1961, Lewis began experiencing nephritis, which resulted in blood poisoning. His illness caused him to miss the autumn term at Cambridge, though his health gradually began improving in 1962 and he returned that April. His health continued to improve and, according to his friend George Sayer, Lewis was fully himself by early 1963.
On 15 July that year, Lewis fell ill and was admitted to the hospital; he had a heart attack at 5:00 pm the next day and lapsed into a coma, but unexpectedly woke the following day at 2:00 pm. After he was discharged from the hospital, Lewis returned to the Kilns, though he was too ill to return to work. As a result, he resigned from his post at Cambridge in August 1963.
Lewis's condition continued to decline, and he was diagnosed with end-stage kidney failure in mid-November. He collapsed in his bedroom at 5:30 pm on 22 November, exactly one week before his 65th birthday, and died a few minutes later. He is buried in the churchyard of Holy Trinity Church, Headington, Oxford. His brother Warren died on 9 April 1973 and was buried in the same grave.
Media coverage of Lewis's death was almost completely overshadowed by news of the assassination of John F. Kennedy, which occurred on the same day (approximately 55 minutes following Lewis's collapse), as did the death of English writer Aldous Huxley, author of Brave New World. This coincidence was the inspiration for Peter Kreeft's book Between Heaven and Hell: A Dialog Somewhere Beyond Death with John F. Kennedy, C. S. Lewis, & Aldous Huxley. Lewis is commemorated on 22 November in the church calendar of the Episcopal Church.
Lewis began his academic career as an undergraduate student at Oxford University, where he won a triple first, the highest honours in three areas of study. He was then elected a Fellow of Magdalen College, Oxford, where he worked for nearly thirty years, from 1925 to 1954. In 1954, he was awarded the newly founded chair of Mediaeval and Renaissance Literature at Cambridge University, and was elected a fellow of Magdalene College. Concerning his appointed academic field, he argued that there was no such thing as an English Renaissance. Much of his scholarly work concentrated on the later Middle Ages, especially its use of allegory. His The Allegory of Love (1936) helped reinvigorate the serious study of late medieval narratives such as the Roman de la Rose.
Lewis was commissioned to write the volume English Literature in the Sixteenth Century (Excluding Drama) for the Oxford History of English Literature. His book A Preface to Paradise Lost is still cited as a criticism of that work. His last academic work, The Discarded Image: An Introduction to Medieval and Renaissance Literature (1964), is a summary of the medieval world view, a reference to the "discarded image" of the cosmos.
Lewis was a prolific writer, and his circle of literary friends became an informal discussion society known as the "Inklings", including J. R. R. Tolkien, Nevill Coghill, Lord David Cecil, Charles Williams, Owen Barfield, and his brother Warren Lewis. Glyer points to December 1929 as the Inklings' beginning date. Lewis's friendship with Coghill and Tolkien grew during their time as members of the Kolbítar, an Old Norse reading group that Tolkien founded and which ended around the time of the inception of the Inklings. At Oxford, he was the tutor of poet John Betjeman, critic Kenneth Tynan, mystic Bede Griffiths, novelist Roger Lancelyn Green and Sufi scholar Martin Lings, among many other undergraduates. The religious and conservative Betjeman detested Lewis, whereas the anti-establishment Tynan retained a lifelong admiration for him.
Of Tolkien, Lewis writes in Surprised by Joy:
When I began teaching for the English Faculty, I made two other friends, both Christians (these queer people seemed now to pop up on every side) who were later to give me much help in getting over the last stile. They were HVV Dyson ... and JRR Tolkien. Friendship with the latter marked the breakdown of two old prejudices. At my first coming into the world I had been (implicitly) warned never to trust a Papist, and at my first coming into the English Faculty (explicitly) never to trust a philologist. Tolkien was both.
In addition to his scholarly work, Lewis wrote several popular novels, including the science fiction Space Trilogy for adults and the Narnia fantasies for children. Most deal implicitly with Christian themes such as sin, humanity's fall from grace, and redemption.
His first novel after becoming a Christian was The Pilgrim's Regress (1933), which depicted his experience with Christianity in the style of John Bunyan's The Pilgrim's Progress. The book was poorly received by critics at the time, although David Martyn Lloyd-Jones, one of Lewis's contemporaries at Oxford, gave him much-valued encouragement. Asked by Lloyd-Jones when he would write another book, Lewis replied, "When I understand the meaning of prayer."
The Space Trilogy (also called the Cosmic Trilogy or Ransom Trilogy) dealt with what Lewis saw as the dehumanizing trends in contemporary science fiction. The first book, Out of the Silent Planet, was apparently written following a conversation with his friend J. R. R. Tolkien about these trends. Lewis agreed to write a "space travel" story and Tolkien a "time travel" one, but Tolkien never completed "The Lost Road", linking his Middle-earth to the modern world. Lewis's main character Elwin Ransom is based in part on Tolkien, a fact to which Tolkien alludes in his letters.
The second novel, Perelandra, depicts a new Garden of Eden on the planet Venus, a new Adam and Eve, and a new "serpent figure" to tempt Eve. The story can be seen as an account of what might have happened if the terrestrial Adam had defeated the serpent and avoided the Fall of Man, with Ransom intervening in the novel to "ransom" the new Adam and Eve from the deceptions of the enemy. The third novel, That Hideous Strength, develops the theme of nihilistic science threatening traditional human values, embodied in Arthurian legend.
Many ideas in the trilogy, particularly opposition to dehumanization as portrayed in the third book, are presented more formally in The Abolition of Man, based on a series of lectures by Lewis at Durham University in 1943. Lewis stayed in Durham, where he says he was overwhelmed by the magnificence of the cathedral. That Hideous Strength is in fact set in the environs of "Edgestow" university, a small English university like Durham, though Lewis disclaims any other resemblance between the two.
Walter Hooper, Lewis's literary executor, discovered a fragment of another science-fiction novel apparently written by Lewis called The Dark Tower. Ransom appears in the story but it is not clear whether the book was intended as part of the same series of novels. The manuscript was eventually published in 1977, though Lewis scholar Kathryn Lindskoog doubts its authenticity.
The Chronicles of Narnia, considered a classic of children's literature, is a series of seven fantasy novels. Written between 1949 and 1954 and illustrated by Pauline Baynes, the series is Lewis's most popular work, having sold over 100 million copies in 41 languages (Kelly 2006) (Guthmann 2005). It has been adapted several times, complete or in part, for radio, television, stage and cinema.
The books contain Christian ideas intended to be easily accessible to young readers. In addition to Christian themes, Lewis also borrows characters from Greek and Roman mythology, as well as traditional British and Irish fairy tales.
Lewis's last novel, Till We Have Faces, a retelling of the myth of Cupid and Psyche, was published in 1956. Although Lewis called it "far and away my best book," it was not as well-reviewed as his previous work.
Lewis wrote several works on Heaven and Hell. One of these, The Great Divorce, is a short novella in which a few residents of Hell take a bus ride to Heaven, where they are met by people who dwell there. The proposition is that they can stay if they choose, in which case they can call the place where they had come from "Purgatory", instead of "Hell", but many find it not to their taste. The title is a reference to William Blake's The Marriage of Heaven and Hell, a concept that Lewis found a "disastrous error". This work deliberately echoes two other more famous works with a similar theme: the Divine Comedy of Dante Alighieri, and Bunyan's The Pilgrim's Progress.
Another short work, The Screwtape Letters, which he dedicated to J. R. R. Tolkien, consists of letters of advice from senior demon Screwtape to his nephew Wormwood on the best ways to tempt a particular human and secure his damnation. Lewis's last novel was Till We Have Faces, which he thought of as his most mature and masterly work of fiction but which was never a popular success. It is a retelling of the myth of Cupid and Psyche from the unusual perspective of Psyche's sister. It is deeply concerned with religious ideas, but the setting is entirely pagan, and the connections with specific Christian beliefs are left implicit.
Before Lewis's conversion to Christianity, he published two books: Spirits in Bondage, a collection of poems, and Dymer, a single narrative poem. Both were published under the pen name Clive Hamilton. Other narrative poems have since been published posthumously, including Launcelot, The Nameless Isle, and The Queen of Drum.
He also wrote The Four Loves, which rhetorically explains four categories of love: friendship, eros, affection, and charity.
In 2009, a partial draft was discovered of Language and Human Nature, which Lewis had begun co-writing with J. R. R. Tolkien, but which was never completed.
Lewis is also regarded by many as one of the most influential Christian apologists of his time, in addition to his career as an English professor and an author of fiction. Mere Christianity was voted best book of the 20th century by Christianity Today in 2000. He has been called "The Apostle to the Skeptics" due to his approach to religious belief as a sceptic, and his following conversion.
Lewis was very interested in presenting an argument from reason against metaphysical naturalism and for the existence of God. Mere Christianity, The Problem of Pain, and Miracles were all concerned, to one degree or another, with refuting popular objections to Christianity, such as the question, "How could a good God allow pain to exist in the world?" He also became a popular lecturer and broadcaster, and some of his writing originated as scripts for radio talks or lectures (including much of Mere Christianity).
According to George Sayer, losing a 1948 debate with Elizabeth Anscombe, also a Christian, led Lewis to re-evaluate his role as an apologist, and his future works concentrated on devotional literature and children's books. Anscombe had a completely different recollection of the debate's outcome and its emotional effect on Lewis. Victor Reppert also disputes Sayer, listing some of Lewis's post-1948 apologetic publications, including the second and revised edition of his Miracles in 1960, in which Lewis addressed Anscombe's criticism. Noteworthy too is Roger Teichman's suggestion in The Philosophy of Elizabeth Anscombe that the intellectual impact of Anscombe's paper on Lewis's philosophical self-confidence should not be over-rated: "... it seems unlikely that he felt as irretrievably crushed as some of his acquaintances have made out; the episode is probably an inflated legend, in the same category as the affair of Wittgenstein's Poker. Certainly, Anscombe herself believed that Lewis's argument, though flawed, was getting at something very important; she thought that this came out more in the improved version of it that Lewis presented in a subsequent edition of Miracles – though that version also had 'much to criticize in it'."
Lewis wrote an autobiography titled Surprised by Joy, which places special emphasis on his own conversion. He also wrote many essays and public speeches on Christian belief, many of which were collected in God in the Dock and The Weight of Glory and Other Addresses.
His most famous works, the Chronicles of Narnia, contain many strong Christian messages and are often considered allegory. Lewis, an expert on the subject of allegory, maintained that the books were not allegory, and preferred to call the Christian aspects of them "suppositional". As Lewis wrote in a letter to a Mrs. Hook in December 1958:
If Aslan represented the immaterial Deity in the same way in which Giant Despair [a character in The Pilgrim's Progress] represents despair, he would be an allegorical figure. In reality, he is an invention giving an imaginary answer to the question, "What might Christ become like, if there really were a world like Narnia and He chose to be incarnate and die and rise again in that world as He actually has done in ours?" This is not allegory at all.
Prior to his conversion, Lewis used the word "Moslem" to refer to Muslims, adherents of Islam; following his conversion, however, he started using "Mohammedans" and described Islam as a Christian heresy rather than an independent religion.
In a much-cited passage from Mere Christianity, Lewis challenged the view that Jesus was a great moral teacher but not God. He argued that Jesus made several implicit claims to divinity, which would logically exclude that claim:
I am trying here to prevent anyone saying the really foolish thing that people often say about Him: 'I'm ready to accept Jesus as a great moral teacher, but I don't accept his claim to be God.' That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic – on the level with the man who says he is a poached egg – or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse. You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronising nonsense about his being a great human teacher. He has not left that open to us. He did not intend to.
Although this argument is sometimes called "Lewis's trilemma", Lewis did not invent it but rather developed and popularized it. It has also been used by Christian apologist Josh McDowell in his book More Than a Carpenter. It has been widely repeated in Christian apologetic literature but largely ignored by professional theologians and biblical scholars.
Lewis's Christian apologetics, and this argument in particular, have been criticized. Philosopher John Beversluis described Lewis's arguments as "textually careless and theologically unreliable", and this particular argument as logically unsound and an example of a false dilemma. The Pluralist theologian John Hick claimed that New Testament scholars do not now support the view that Jesus claimed to be God. The Anglican New Testament scholar N. T. Wright criticizes Lewis for failing to recognize the significance of Jesus's Jewish identity and setting – an oversight which "at best, drastically short-circuits the argument" and which lays Lewis open to criticism that his argument "doesn't work as history, and it backfires dangerously when historical critics question his reading of the gospels", although he argues that this "doesn't undermine the eventual claim".
Lewis used a similar argument in The Lion, the Witch and the Wardrobe, when the old Professor advises his young guests that their sister's claims of a magical world must logically be taken as either lies, madness, or truth.
One of the main theses in Lewis's apologia is that there is a common morality known throughout humanity, which he calls "natural law". In the first five chapters of Mere Christianity, Lewis discusses the idea that people have a standard of behaviour to which they expect people to adhere. Lewis claims that people all over the earth know what this law is and when they break it. He goes on to claim that there must be someone or something behind such a universal set of principles.
These then are the two points that I wanted to make. First, that human beings, all over the earth, have this curious idea that they ought to behave in a certain way, and cannot really get rid of it. Secondly, that they do not in fact behave in that way. They know the Law of Nature; they break it. These two facts are the foundation of all clear thinking about ourselves and the universe we live in.
Lewis also portrays Universal Morality in his works of fiction. In The Chronicles of Narnia he describes Universal Morality as the "deep magic" which everyone knew.
In the second chapter of Mere Christianity, Lewis recognizes that "many people find it difficult to understand what this Law of Human Nature ... is." And he responds first to the idea "that the Moral Law is simply our herd instinct" and second to the idea "that the Moral Law is simply a social convention". In responding to the second idea Lewis notes that people often complain that one set of moral ideas is better than another, but that this actually argues for there existing some "Real Morality" to which they are comparing other moralities. Finally, he notes that sometimes differences in moral codes are exaggerated by people who confuse differences in beliefs about morality with differences in beliefs about facts:
I have met people who exaggerate the differences, because they have not distinguished between differences of morality and differences of belief about facts. For example, one man said to me, "Three hundred years ago people in England were putting witches to death. Was that what you call the Rule of Human Nature or Right Conduct?" But surely the reason we do not execute witches is that we do not believe there are such things. If we did – if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather, surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did. There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.
Lewis also had fairly progressive views on the topic of "animal morality", in particular the suffering of animals, as is evidenced by several of his essays: most notably, On Vivisection and "On the Pains of Animals".
Lewis continues to attract a wide readership. In 2008, The Times ranked him eleventh on their list of "the 50 greatest British writers since 1945". Readers of his fiction are often unaware of what Lewis considered the Christian themes of his works. His Christian apologetics are read and quoted by members of many Christian denominations. In 2013, on the 50th anniversary of his death, Lewis joined some of Britain's greatest writers recognized at Poets' Corner, Westminster Abbey. The dedication service, at noon on 22 November 2013, included a reading from The Last Battle by Douglas Gresham, younger stepson of Lewis. Flowers were laid by Walter Hooper, trustee and literary advisor to the Lewis Estate. An address was delivered by former Archbishop of Canterbury Rowan Williams. The floor stone inscription is a quotation from an address by Lewis:
I believe in Christianity as I believe that the Sun has risen, not only because I see it but because by it I see everything else.
Lewis has been the subject of several biographies, a few of which were written by close friends, such as Roger Lancelyn Green and George Sayer. In 1985, the screenplay Shadowlands by William Nicholson dramatized Lewis's life and relationship with Joy Davidman Gresham. It was aired on British television starring Joss Ackland and Claire Bloom. This was also staged as a theatre play starring Nigel Hawthorne in 1989 and made into the 1993 feature film Shadowlands starring Anthony Hopkins and Debra Winger.
Many books have been inspired by Lewis, including A Severe Mercy by his correspondent and friend Sheldon Vanauken. The Chronicles of Narnia has been particularly influential. Modern children's literature has been more or less influenced by Lewis's series, such as Daniel Handler's A Series of Unfortunate Events, Eoin Colfer's Artemis Fowl, Philip Pullman's His Dark Materials, and J. K. Rowling's Harry Potter.(Hilliard 2005) Pullman is an atheist and is known to be sharply critical of C. S. Lewis's work, accusing Lewis of featuring religious propaganda, misogyny, racism, and emotional sadism in his books. However, he has also modestly praised The Chronicles of Narnia for being a "more serious" work of literature in comparison with Tolkien's "trivial" The Lord of the Rings. Authors of adult fantasy literature such as Tim Powers have also testified to being influenced by Lewis's work.
In A Sword Between the Sexes? C. S. Lewis and the Gender Debates, Mary Stewart Van Leeuwen finds in Lewis's work "a hierarchical and essentialist view of class and gender" corresponding to an upbringing during the Edwardian era.
Most of Lewis's posthumous work has been edited by his literary executor Walter Hooper. Kathryn Lindskoog, an independent Lewis scholar, argued that Hooper's scholarship is not reliable and that he has made false statements and attributed forged works to Lewis. Lewis's stepson, Douglas Gresham, denies the forgery claims, saying that "The whole controversy thing was engineered for very personal reasons ... Her fanciful theories have been pretty thoroughly discredited."
A bronze statue of Lewis's character Digory from The Magician's Nephew stands in Belfast's Holywood Arches in front of the Holywood Road Library.
Several C. S. Lewis Societies exist around the world, including one which was founded in Oxford in 1982. The C.S. Lewis Society at the University of Oxford meets at Pusey House during term time to discuss papers on the life and works of Lewis and the other Inklings, and generally appreciate all things Lewisian.
Live-action film adaptations have been made of three of The Chronicles of Narnia: The Lion, the Witch, and the Wardrobe (2005), Prince Caspian (2008) and The Voyage of the Dawn Treader (2010).
Lewis is featured as a main character in The Chronicles of the Imaginarium Geographica series by James A. Owen. He is one of two characters in Mark St. Germain's 2009 play Freud's Last Session, which imagines a meeting between Lewis, aged 40, and Sigmund Freud, aged 83, at Freud's house in Hampstead, London, in 1939, as the Second World War is about to break out.
In 2021, The Most Reluctant Convert, a biographical drama about Lewis's life and conversion, was released.
The CS Lewis Nature Reserve, on ground owned by Lewis, lies behind his house, The Kilns. There is public access. | [

] | Clive Staples Lewis was a British writer, literary scholar, and Anglican lay theologian. He held academic positions in English literature at both Magdalen College, Oxford (1925–1954), and Magdalene College, Cambridge (1954–1963). He is best known as the author of The Chronicles of Narnia, but he is also noted for his other works of fiction, such as The Screwtape Letters and The Space Trilogy, and for his non-fiction Christian apologetics, including Mere Christianity, Miracles, and The Problem of Pain. Lewis was a close friend of J. R. R. Tolkien, author of The Lord of the Rings. Both men served on the English faculty at Oxford University and were active in the informal Oxford literary group known as the Inklings. According to Lewis's 1955 memoir Surprised by Joy, he was baptized in the Church of Ireland but fell away from his faith during adolescence. Lewis returned to Anglicanism at the age of 32, owing to the influence of Tolkien and other friends, and he became an "ordinary layman of the Church of England". Lewis's faith profoundly affected his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim. Lewis wrote more than 30 books which have been translated into more than 30 languages and have sold millions of copies. The books that make up The Chronicles of Narnia have sold the most and have been popularized on stage, TV, radio, and cinema. His philosophical writings are widely cited by Christian scholars from many denominations. In 1956, Lewis married American writer Joy Davidman; she died of cancer four years later at the age of 45. Lewis died on 22 November 1963 from kidney failure, one week before his 65th birthday. In 2013, on the 50th anniversary of his death, Lewis was honoured with a memorial in Poets' Corner in Westminster Abbey. | 2001-11-07T01:35:02Z | 2023-12-27T20:22:21Z | [

5,814 | Chinese dominoes | Chinese dominoes are used in several tile-based games, namely, tien gow, pai gow, tiu u and kap tai shap. In Cantonese they are called gwāt pái (骨牌), which literally means "bone tiles"; it is also the name of a northern Chinese game, where the rules are quite different from the southern Chinese version of tien gow.
Ming author Xie Zhaozhe (1567–1624) records the legend of dominoes having been presented to Song Emperor Huizong in 1112. However the contemporary Li Qingzhao (1084 – c. 1155) made no mention of dominoes in her compendium of games.
In China, early "domino" tiles were functionally identical to playing cards. An identifiable version of Chinese dominoes developed in the 12th or 13th century.
The oldest confirmed written mention of dominoes in China comes from the Former Events in Wulin (i.e. the capital Hangzhou) written by the Yuan Dynasty (1271–1368) author Zhou Mi (1232–1298), who listed "pupai" (gambling plaques or dominoes) as well as dice as items sold by peddlers during the reign of Song Emperor Xiaozong (r. 1162–1189). Andrew Lo asserts that Zhou Mi meant dominoes when referring to pupai, since the Ming author Lu Rong (1436–1494) explicitly defined pupai as dominoes (in regards to a story of a suitor who won a maiden's hand by drawing out four winning pupai from a set). Tiles dating from the 12th to 14th centuries have survived. Unlike most modern tiles they are white with black and red pips.
The earliest known manual written about dominoes is the Manual of the Xuanhe Period (《宣和牌譜》) written by Qu You (1341–1427), but some Chinese scholars believe this manual is a forgery from a later time. In the Encyclopedia of a Myriad of Treasures, Zhang Pu (1602–1641) described the game of laying out dominoes as pupai, although the character for pu had changed, yet retained a similar pronunciation.
During the Qing dynasty (1644-1912), the suits known as "Chinese" and "barbarian" were renamed to "civil" and "military" respectively to avoid offending the ruling Manchus. Tiles with blank ends, like those found in Western "double-six" dominoes, once existed during the 17th century. These games employed two sets of "double-six" tiles. It is possible that these were the types of dominoes that made it to Europe the following century. However, the 32-piece Chinese domino set, made to represent each possible face of two thrown dice and thus have no blank faces, differs from the 28-piece domino set found in the West during the mid 18th century. Chinese dominoes with blank faces were known during the 17th century. Each domino originally represented one of the 21 results of throwing two six-sided dice (2d6). One half of each domino is set with the pips from one die and the other half contains the pips from the second die. Chinese sets also introduce duplicates of some throws and divide the tiles into two suits: military and civil. Chinese dominoes are also longer than typical European ones.
Traditional Chinese domino games include Tien Gow, Pai Gow, Che Deng, and others.
Each tile pattern in the Chinese domino set is equivalent to a single outcome when two six-sided dice are thrown. Each combination is only used once, so there are 21 unique possible patterns. Eleven of these 21 unique patterns are repeated to make a total of 32 tiles in a Chinese dominoes set. The 32-tile set is divided into two "suits" or groups called "military" and "civil". There are no markings on the tiles to distinguish these suits; a player must simply remember which tiles belong to which group. There are two each of the eleven civil suit tiles (6-6, 1-1, 4-4, 1-3, 5-5, 3-3, 2-2, 5-6, 4-6, 1-6, 1-5) and one each of the ten military suit tiles (3-6, 4-5; 2-6, 3-5; 2-5, 3-4; 2-4; 1-4, 2-3; 1-2).
Each civil tile also has a Chinese name (and common rough translation to English):
The civil tiles are ranked according to the Chinese cultural significance of the tile names, and must be memorized. The hendiatris of heaven, earth, and man [zh] (天地人) dates back for over two thousand years while the harmony (和) of the three have been in dice and domino games since at least the Ming dynasty. Remembering the suits and rankings of the tiles is easier if one understands the Chinese names of the tiles and the symbolism behind them.
The military tiles are named and ranked according to the total pips or points on the tiles. For example, the "nines" (3-6 and 4-5) rank higher than the "eights" (2-6 and 3-5). The rankings of the individual tiles are similar in most games. However, the ranking of combinations of tiles is slightly different in Pai Gow and Tien Gow.
Since there is only one of each military tile, these are usually grouped in four mixed "pairs" of equivalent total points: nines, eights, sevens, and fives; for example, the 3-6 and 4-5 tiles "match" because they have same total points (nine) and both are in the military suit. Among the military tiles, individual tiles of the same pair rank equally, such as 1-4 and 2-3, each totaling five.
The 2-4 (six) and 1-2 (three) military tiles also are paired together in many games despite the nominal difference in total points. They are the only tiles in the entire set that have no corresponding tile in the military suit, considering sums. In Pai Gow both of these tiles may be scored as three or six, depending on which is more advantageous. This pair when played together is considered a suit on its own, called the gi jun (至尊 supreme). It is the highest ranking pair in the game of Pai Gow, though the tiles rank low individually (in their normal order). When either tile of this pair is played individually in the game of Tien Gow, each takes its regular ranking according to the total points among the other military suit tiles.
Stewart Culin stated that traditional dominoes are made of Chinese ebony with measurements of 2+5⁄8 in (67 mm) long, 7⁄8 in (22 mm) wide, and 3⁄8 in (9.5 mm) thick.
Values are marked with white and red pips. Using the same coloring scheme as traditional Chinese dice, every half-domino with 1 or 4 pips has those pips colored red; for example, the 4-5 domino has four red pips and five white pips. The only exception is the pair of 6-6 tiles. Half of the pips on the 6-6 domino are colored red to make them stand out as the top ranking tiles.
Typically, one of the short edges is marked with a single red pip, and the backs may be marked with three pips, arrayed diagonally white-red-white.
There are also sets with where the tiles have Xiangqi characters next to the pips. As Xiangqi also has 32 pieces, these dual use sets can be used to play Giog.
Variant sets include the Digging Flowers (挖花) game, which use the same 21 patterns generated by the 2d6 combination; some tiles have flowers or frames printed on them while others have their values duplicated. In addition, a Digging Flowers set may include several bonus tiles from mahjong, including flower, season, and blank tiles.
Dominoes from Korea also come in a set of 32 and bear markings schematically identical to Chinese dominoes, based on the throw of two dice, although the tiles are closer in size and shape to those used in mahjong, measuring 3⁄4 in × 7⁄16 in × 3⁄16 in (19.1 mm × 11.1 mm × 4.8 mm), and the pip size may vary, especially for the 1- and 4-pip halves. The pairings for the "military" suit also differ: 1-2 and 4-5; 1-4 and 2-3, 2-4 and 3-4, 2-5 and 3-5, and 2-6 and 3-6.
The eponymous game of Bone Tiles (gǔpái in Mandarin) is played in northern and central China and as far south as Hunan. The name suggests that it is or became the default game played with dominoes in those regions. It is a trick-taking game similar to Tien Gow but has been simplified. In single-tile tricks, the civil and military suits have been merged into a single suit. In double-tile tricks, there is a new ranking order similar to Pai Gow. Triple-tile and quadruple-tile tricks are not allowed as in older versions of Tien Gow. Scoring has been simplified to number of stacks won. | [

5,816 | Cenozoic | The Cenozoic (/ˌsiːnəˈzoʊ.ɪk, ˌsɛn-/ SEE-nə-ZOH-ik, SEN-ə-; lit. 'new life') is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterised by the dominance of mammals, birds, and angiosperms (flowering plants). It is the latest of three geological eras, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor.
The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammals – the eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that large mammals and birds dominated life on Earth. The continents also moved into their current positions during this era.
The climate during the early Cenozoic was warmer than today, particularly during the Paleocene–Eocene Thermal Maximum. However, the Eocene to Oligocene transition and the Quaternary glaciation dried and cooled Earth.
Cenozoic derives from the Greek words kainós (καινός 'new') and zōḗ (ζωή 'life'). The name was proposed in 1840 by the British geologist John Phillips (1800–1874), who originally spelled it Kainozoic. The era is also known as the Cænozoic, Caenozoic, or Cainozoic (/ˌkaɪ.nəˈzoʊ.ɪk, ˌkeɪ-/).
In name, the Cenozoic (lit. 'new life') is comparable to the preceding Mesozoic ('middle life') and Paleozoic ('old life') Eras, as well as to the Proterozoic ('earlier life') Eon.
The Cenozoic is divided into three periods: the Paleogene, Neogene, and Quaternary; and seven epochs: the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene. The Quaternary Period was officially recognised by the International Commission on Stratigraphy in June 2009. In 2004, the Tertiary Period was officially replaced by the Paleogene and Neogene Periods. The common use of epochs during the Cenozoic helps palaeontologists better organise and group the many significant events that occurred during this comparatively short interval of time. Knowledge of this era is more detailed than any other era because of the relatively young, well-preserved rocks associated with it.
The Paleogene spans from the extinction of non-avian dinosaurs, 66 million years ago, to the dawn of the Neogene, 23.03 million years ago. It features three epochs: the Paleocene, Eocene and Oligocene.
The Paleocene Epoch lasted from 66 million to 56 million years ago. Modern placental mammals originated during this time. The devastation of the K–Pg extinction event included the extinction of large herbivores, which permitted the spread of dense but usually species-poor forests. The Early Paleocene saw the recovery of Earth. The continents began to take their modern shape, but all the continents and the subcontinent of India were separated from each other. Afro-Eurasia was separated by the Tethys Sea, and the Americas were separated by the strait of Panama, as the isthmus had not yet formed. This epoch featured a general warming trend, with jungles eventually reaching the poles. The oceans were dominated by sharks as the large reptiles that had once predominated were extinct. Archaic mammals filled the world such as creodonts (extinct carnivores, unrelated to existing Carnivora).
The Eocene Epoch ranged from 56 million years to 33.9 million years ago. In the Early-Eocene, species living in dense forest were unable to evolve into larger forms, as in the Paleocene. Among them were early primates, whales and horses along with many other early forms of mammals. At the top of the food chains were huge birds, such as Paracrax. Carbon dioxide levels were approximately 1,400 ppm. The temperature was 30 degrees Celsius with little temperature gradient from pole to pole. In the Mid-Eocene, the Antarctic Circumpolar Current between Australia and Antarctica formed. This disrupted ocean currents worldwide and as a result caused a global cooling effect, shrinking the jungles. This allowed mammals to grow to mammoth proportions, such as whales which, by that time, had become almost fully aquatic. Mammals like Andrewsarchus were at the top of the food-chain. The Late Eocene saw the rebirth of seasons, which caused the expansion of savanna-like areas, along with the evolution of grasses. The end of the Eocene was marked by the Eocene–Oligocene extinction event, the European face of which is known as the Grande Coupure.
The Oligocene Epoch spans from 33.9 million to 23.03 million years ago. The Oligocene featured the expansion of grasslands which had led to many new species to evolve, including the first elephants, cats, dogs, marsupials and many other species still prevalent today. Many other species of plants evolved in this period too. A cooling period featuring seasonal rains was still in effect. Mammals still continued to grow larger and larger.
The Neogene spans from 23.03 million to 2.58 million years ago. It features 2 epochs: the Miocene, and the Pliocene.
The Miocene Epoch spans from 23.03 to 5.333 million years ago and is a period in which grasses spread further, dominating a large portion of the world, at the expense of forests. Kelp forests evolved, encouraging the evolution of new species, such as sea otters. During this time, perissodactyla thrived, and evolved into many different varieties. Apes evolved into 30 species. The Tethys Sea finally closed with the creation of the Arabian Peninsula, leaving only remnants as the Black, Red, Mediterranean and Caspian Seas. This increased aridity. Many new plants evolved: 95% of modern seed plants families were present by the end of the Miocene.
The Pliocene Epoch lasted from 5.333 to 2.58 million years ago. The Pliocene featured dramatic climatic changes, which ultimately led to modern species of flora and fauna. The Mediterranean Sea dried up for several million years (because the ice ages reduced sea levels, disconnecting the Atlantic from the Mediterranean, and evaporation rates exceeded inflow from rivers). Australopithecus evolved in Africa, beginning the human branch. The isthmus of Panama formed, and animals migrated between North and South America during the great American interchange, wreaking havoc on local ecologies. Climatic changes brought: savannas that are still continuing to spread across the world; Indian monsoons; deserts in central Asia; and the beginnings of the Sahara desert. The world map has not changed much since, save for changes brought about by the glaciations of the Quaternary, such as the Great Lakes, Hudson Bay, and the Baltic sea.
The Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene.
The Pleistocene lasted from 2.58 million to 11,700 years ago. This epoch was marked by ice ages as a result of the cooling trend that started in the Mid-Eocene. There were at least four separate glaciation periods marked by the advance of ice caps as far south as 40° N in mountainous areas. Meanwhile, Africa experienced a trend of desiccation which resulted in the creation of the Sahara, Namib, and Kalahari deserts. Many animals evolved including mammoths, giant ground sloths, dire wolves, sabre-toothed cats, and Homo sapiens. 100,000 years ago marked the end of one of the worst droughts in Africa, and led to the expansion of primitive humans. As the Pleistocene drew to a close, a major extinction wiped out much of the world's megafauna, including some of the hominid species, such as Neanderthals. All the continents were affected, but Africa to a lesser extent. It still retains many large animals, such as hippos.
The Holocene began 11,700 years ago and lasts to the present day. All recorded history and "the Human history" lies within the boundaries of the Holocene Epoch. Human activity is blamed for a mass extinction that began roughly 10,000 years ago, though the species becoming extinct have only been recorded since the Industrial Revolution. This is sometimes referred to as the "Sixth Extinction". It is often cited that over 322 recorded species have become extinct due to human activity since the Industrial Revolution, but the rate may be as high as 500 vertebrate species alone, the majority of which have occurred after 1900.
Geologically, the Cenozoic is the era when the continents moved into their current positions. Australia-New Guinea, having split from Pangea during the early Cretaceous, drifted north and, eventually, collided with Southeast Asia; Antarctica moved into its current position over the South Pole; the Atlantic Ocean widened and, later in the era (2.8 million years ago), South America became attached to North America with the isthmus of Panama.
India collided with Asia 55 to 45 million years ago creating the Himalayas; Arabia collided with Eurasia, closing the Tethys Ocean and creating the Zagros Mountains, around 35 million years ago.
The break-up of Gondwana in Late Cretaceous and Cenozoic times led to a shift in the river courses of various large African rivers including the Congo, Niger, Nile, Orange, Limpopo and Zambezi.
In the Cretaceous, the climate was hot and humid with lush forests at the poles, there was no permanent ice and sea levels were around 300 metres higher than today. This continued for the first 10 million years of the Paleocene, culminating in the Paleocene–Eocene Thermal Maximum about 55.5 million years ago. Around 50 million years ago Earth entered a period of long term cooling. This was mainly due to the collision of India with Eurasia, which caused the rise of the Himalayas: the upraised rocks eroded and reacted with CO2 in the air, causing a long-term reduction in the proportion of this greenhouse gas in the atmosphere. Around 35 million years ago permanent ice began to build up on Antarctica. The cooling trend continued in the Miocene, with relatively short warmer periods. When South America became attached to North America creating the Isthmus of Panama around 2.8 million years ago, the Arctic region cooled due to the strengthening of the Humboldt and Gulf Stream currents, eventually leading to the glaciations of the Quaternary ice age, the current interglacial of which is the Holocene Epoch. Recent analysis of the geomagnetic reversal frequency, oxygen isotope record, and tectonic plate subduction rate, which are indicators of the changes in the heat flux at the core mantle boundary, climate and plate tectonic activity, shows that all these changes indicate similar rhythms on million years' timescale in the Cenozoic Era occurring with the common fundamental periodicity of ~13 Myr during most of the time.
Early in the Cenozoic, following the K-Pg event, the planet was dominated by relatively small fauna, including small mammals, birds, reptiles, and amphibians. From a geological perspective, it did not take long for mammals and birds to greatly diversify in the absence of the dinosaurs that had dominated during the Mesozoic. Some flightless birds grew larger than humans. These species are sometimes referred to as "terror birds", and were formidable predators. Mammals came to occupy almost every available niche (both marine and terrestrial), and some also grew very large, attaining sizes not seen in most of today's terrestrial mammals. The ranges of many Cenozoic bird clades were governed by latitude and temperature and have contracted over the course of this era as the world cooled.
During the Cenozoic, mammals proliferated from a few small, simple, generalised forms into a diverse collection of terrestrial, marine, and flying animals, giving this period its other name, the Age of Mammals. The Cenozoic is just as much the age of savannas, the age of co-dependent flowering plants and insects, and the age of birds. Grasses also played a very important role in this era, shaping the evolution of the birds and mammals that fed on them. One group that diversified significantly in the Cenozoic as well were the snakes. Evolving in the Cenozoic, the variety of snakes increased tremendously, resulting in many colubrids, following the evolution of their current primary prey source, the rodents.
In the earlier part of the Cenozoic, the world was dominated by the gastornithid birds, terrestrial crocodiles like Pristichampsus, large sharks such as Otodus, and a handful of primitive large mammal groups like uintatheres, mesonychians, and pantodonts. But as the forests began to recede and the climate began to cool, other mammals took over.
The Cenozoic is full of mammals both strange and familiar, including chalicotheres, creodonts, whales, primates, entelodonts, sabre-toothed cats, mastodons and mammoths, three-toed horses, giant rhinoceros like Paraceratherium, the rhinoceros-like brontotheres, various bizarre groups of mammals from South America, such as the vaguely elephant-like pyrotheres and the dog-like marsupial relatives called borhyaenids and the monotremes and marsupials of Australia. | [

5,820 | Confucianism | Confucianism, also known as Ruism or Ru classicism, is a system of thought and behavior originating in ancient China, and is variously described as a tradition, philosophy, (humanistic or rationalistic) religion, theory of government, or way of life. Confucianism developed from what was later called the Hundred Schools of Thought from the teachings of the Chinese philosopher Confucius (551–479 BCE). Confucius considered himself a transmitter of cultural values inherited from the Xia (c. 2070–1600 BCE), Shang (c. 1600–1046 BCE) and Western Zhou dynasties (c. 1046–771 BCE). Confucianism was suppressed during the Legalist and autocratic Qin dynasty (221–206 BCE), but survived. During the Han dynasty (206 BCE – 220 CE), Confucian approaches edged out the "proto-Taoist" Huang–Lao as the official ideology, while the emperors mixed both with the realist techniques of Legalism.
Confucianism regards texts such as the Five Classics as examples that should be followed to increase the harmony of the family, social order as a whole, and the world. A Confucian revival began during the Tang dynasty (618–907 CE). In the late Tang, Confucianism developed in response to Buddhism and Taoism and was reformulated as Neo-Confucianism. This reinvigorated form was adopted as the basis of the imperial exams and the core philosophy of the scholar-official class in the Song dynasty (960–1297). The abolition of the examination system in 1905 marked the end of official Confucianism. The intellectuals of the New Culture Movement of the early twentieth century blamed Confucianism for China's weaknesses. They searched for new doctrines to replace Confucian teachings; some of these new ideologies include the "Three Principles of the People" with the establishment of the Republic of China, and then Maoism under the People's Republic of China. In the late twentieth century, the Confucian work ethic has been credited with the rise of the East Asian economy.
With particular emphasis on the importance of the family and social harmony, rather than on an otherworldly source of spiritual values, the core of Confucianism is humanistic. According to American philosopher Herbert Fingarette's conceptualisation of Confucianism as a philosophical system which regards "the secular as sacred", Confucianism transcends the dichotomy between religion and humanism, considering the ordinary activities of human life—and especially human relationships—as a manifestation of the sacred, because they are the expression of humanity's moral nature (性; xìng), which has a transcendent anchorage in tian (天; tiān; 'heaven'). While the Confucian concept of tian shares some similarities with the concept of a deity, it is primarily an impersonal absolute principle like the tao or the Brahman. Most scholars and practitioners do not think of tian as a god, and the deities that many Confucians worship do not originate from orthodox Confucianism. Confucianism focuses on the practical order that is given by a this-worldly awareness of tian.
The worldly concern of Confucianism rests upon the belief that human beings are fundamentally good, and teachable, improvable, and perfectible through personal and communal endeavor, especially self-cultivation and self-creation. Confucian thought focuses on the cultivation of virtue in a morally organised world. Some of the basic Confucian ethical concepts and practices include ren, yi, li, and zhi. Ren is the essence of the human being which manifests as compassion. It is the virtue-form of Heaven. Yi is the upholding of righteousness and the moral disposition to do good. Li is a system of ritual norms and propriety that determines how a person should properly act in everyday life in harmony with the law of Heaven. Zhi (智; zhì) is the ability to see what is right and fair, or the converse, in the behaviors exhibited by others. Confucianism holds one in contempt, either passively or actively, for failure to uphold the cardinal moral values of ren and yi.
Traditionally, cultures and countries in the East Asian cultural sphere are strongly influenced by Confucianism, including China, Taiwan, Korea, Japan, and Vietnam, as well as various territories settled predominantly by Han Chinese people, such as Singapore and Myanmar's Kokang. Today, it has been credited for shaping East Asian societies and overseas Chinese communities, and to some extent, other parts of Asia. Most Confucianist movements have had significant differences from the original Zhou-era teachings, and are typically much more complex because of their reliance on "elaborate doctrine" and other factors such as traditions with long histories. In the past few decades, there have been talks of a "Confucian Revival" in the academic and the scholarly community, and there has been a grassroots proliferation of various types of Confucian churches. In late 2015, many Confucian personalities formally established a national Confucian Church (孔圣会; 孔聖會; Kǒngshènghuì) in China to unify the many Confucian congregations and civil society organisations.
Strictly speaking, there is no term in Chinese which directly corresponds to "Confucianism". The closest catch-all term for things related to Confucianism is the word ru (儒; rú). Its literal meanings in modern Chinese include 'scholar', 'learned', or 'refined man'. In Old Chinese the word had a distinct set of meanings, including 'to tame', 'to mould', 'to educate', and 'to refine'. Several different terms, some of which with modern origin, are used in different situations to express different facets of Confucianism, including:
Three of them use ru. These names do not use the name "Confucius" at all, but instead focus on the ideal of the Confucian man. The use of the term "Confucianism" has been avoided by some modern scholars, who favor "Ruism" and "Ruists" instead. Robert Eno argues that the term has been "burdened ... with the ambiguities and irrelevant traditional associations". Ruism, as he states, is more faithful to the original Chinese name for the school.
The term "Traditionalist" has been suggested by David Schaberg to emphasize the connection to the past, its standards, and inherited forms, in which Confucius himself placed so much importance. This translation of the word ru is followed by e.g. Yuri Pines.
According to Zhou Youguang, ru originally referred to shamanic methods of holding rites and existed before Confucius's times, but with Confucius it came to mean devotion to propagating such teachings to bring civilisation to the people. Confucianism was initiated by the disciples of Confucius, developed by Mencius (c. 372–289 BCE) and inherited by later generations, undergoing constant transformations and restructuring since its establishment, but preserving the principles of humaneness and righteousness at its core.
In the Western world, the character for water is often used as a symbol for Confucianism, which is not the case in modern China. However, the five phases were used as important symbols representing leadership in Han dynasty thought, including Confucianist works.
Traditionally, Confucius was thought to be the author or editor of the Five Classics which were the basic texts of Confucianism, all edited into their received versions around 500 years later by Imperial Librarian Liu Xin. The scholar Yao Xinzhong allows that there are good reasons to believe that Confucian classics took shape in the hands of Confucius, but that "nothing can be taken for granted in the matter of the early versions of the classics". Yao suggests that most modern scholars hold the "pragmatic" view that Confucius and his followers did not intend to create a system of classics, but nonetheless "contributed to their formation".
The scholar Tu Weiming explains these classics as embodying "five visions" which underlie the development of Confucianism:
Confucianism revolves around the pursuit of the unity of the individual self and tian ("heaven"). Put it another way, it focuses on the relationship between humanity and heaven. The principle or way of Heaven (tian li or tian tao) is the order of the world and the source of divine authority. Tian li or tian tao is monistic, meaning that it singular and indivisible. Individuals may realise their humanity and become one with Heaven through the contemplation of such order. This transformation of the self may be extended to the family and society to create a harmonious community. Joël Thoraval studied Confucianism as a diffused civil religion in contemporary China, finding that it expresses itself in the widespread worship of five cosmological entities: Heaven and Earth (地; dì), the sovereign or the government (君; jūn), ancestors (親; qīn) and masters (師; shī).
According to the scholar Stephan Feuchtwang, in Chinese cosmology, which is not merely Confucian but shared by many Chinese religions, "the universe creates itself out of a primary chaos of material energy" (hundun and qi), organising through the polarity of yin and yang which characterises any thing and life. Creation is therefore a continuous ordering; it is not a creation ex nihilo. "Yin and yang are the invisible and visible, the receptive and the active, the unshaped and the shaped; they characterise the yearly cycle (winter and summer), the landscape (shady and bright), the sexes (female and male), and even sociopolitical history (disorder and order). Confucianism is concerned with finding "middle ways" between yin and yang at every new configuration of the world."
Confucianism conciliates both the inner and outer polarities of spiritual cultivation, that is to say self-cultivation and world redemption, synthesised in the ideal of "sageliness within and kingliness without". Ren, translated as "humaneness" or the essence proper of a human being, is the character of compassionate mind; it is the virtue endowed by Heaven and at the same time the means by which man may achieve oneness with Heaven comprehending his own origin in Heaven and therefore divine essence. In the Datong Shu [zh], it is defined as "to form one body with all things" and "when the self and others are not separated ... compassion is aroused".
"Lord Heaven" and "Jade Emperor" were terms for a Confucianist supreme deity who was an anthropromorphized tian, and some conceptions of it thought of the two names as synonymous.
Tian, a key concept in Chinese thought, refers to the God of Heaven, the northern culmen of the skies and its spinning stars, earthly nature and its laws which come from Heaven, to 'Heaven and Earth' (that is, "all things"), and to the awe-inspiring forces beyond human control. There are so many uses in Chinese thought that it is impossible to give a single English translation.
Confucius used the term in a mystical way. He wrote in the Analects (7.23) that tian gave him life, and that tian watched and judged (6.28; 9.12). In 9.5 Confucius says that a person may know the movements of tian, and this provides with the sense of having a special place in the universe. In 17.19 Confucius says that tian spoke to him, though not in words. The scholar Ronnie Littlejohn warns that tian was not to be interpreted as a personal God comparable to that of the Abrahamic faiths, in the sense of an otherworldly or transcendent creator. Rather it is similar to what Taoists meant by Dao: "the way things are" or "the regularities of the world", which Stephan Feuchtwang equates with the ancient Greek concept of physis, "nature" as the generation and regenerations of things and of the moral order. Tian may also be compared to the Brahman of Hindu and Vedic traditions. The scholar Promise Hsu, in the wake of Robert B. Louden, explained 17:19 ("What does Tian ever say? Yet there are four seasons going round and there are the hundred things coming into being. What does Tian say?") as implying that even though Tian is not a "speaking person", it constantly "does" through the rhythms of nature, and communicates "how human beings ought to live and act", at least to those who have learnt to carefully listen to it.
Duanmu Ci, a disciple of Confucius, said that Tian had set the master on the path to become a wise man (9.6). In 7.23 Confucius says that he has no doubt left that Tian gave him life, and from it he had developed right virtue (de). In 8.19, he says that the lives of the sages are interwoven with Tian.
Regarding personal gods (shen, energies who emanate from and reproduce Tian) enliving nature, in the Analects Confucius says that it is appropriate (yi) for people to worship (敬; jìng) them, although only through proper rites (li), implying respect of positions and discretion. Confucius himself was a ritual and sacrificial master.
Answering to a disciple who asked whether it is better to sacrifice to the god of the stove or to the god of the family (a popular saying), in 3.13 Confucius says that in order to appropriately pray gods one should first know and respect Heaven. In 3.12, he explains that religious rituals produce meaningful experiences, and one has to offer sacrifices in person, acting in presence, otherwise "it is the same as not having sacrificed at all". Rites and sacrifices to the gods have an ethical importance: they generate good life, because taking part in them leads to the overcoming of the self. Analects 10.11 tells that Confucius always took a small part of his food and placed it on the sacrificial bowls as an offering to his ancestors.
Some Confucian movements worship Confucius, although not as a supreme being or anything else approaching the power of tian or the tao, and/or gods from Chinese folk religion. These movements are not a part of mainstream Confucianism, although the boundary between Chinese folk religion and Confucianism can be blurred.
Other movements, such as Mohism which was later absorbed by Taoism, developed a more theistic idea of Heaven. Feuchtwang explains that the difference between Confucianism and Taoism primarily lies in the fact that the former focuses on the realisation of the starry order of Heaven in human society, while the latter on the contemplation of the Dao which spontaneously arises in nature. However, Confucianism does venerate many aspects of nature and also respects various tao, as well as what Confucius saw as the main tao, the "[Way] of Heaven."
The Way of Heaven involves "lifelong and sincere devotion to traditional cultural forms" and wu wei, "a state of spontaneous harmony between individual inclinations and the sacred Way".
Kelly James Clark argued that Confucius himself saw Tian as an anthropomorphic god that Clark hypothetically refers to as "Heavenly Supreme Emperor", although most other scholars on Confucianism disagree with this view.
As explained by Stephan Feuchtwang, the order coming from Heaven preserves the world, and has to be followed by humanity finding a "middle way" between yin and yang forces in each new configuration of reality. Social harmony or morality is identified as patriarchy, which is expressed in the worship of ancestors and deified progenitors in the male line, at ancestral shrines.
Confucian ethical codes are described as humanistic. They may be practiced by all the members of a society. Confucian ethics is characterised by the promotion of virtues, encompassed by the Five Constants, elaborated by Confucian scholars out of the inherited tradition during the Han dynasty. The Five Constants are:
These are accompanied by the classical four virtues (四字; sìzì), one of which (Yi) is also included among the Five Constants:
There are many other traditionally Confucian values, such as 'honesty' (诚; chéng), 'bravery' (勇; yǒng), 'incorruptibility' (廉; lián), 'kindness', 'forgiveness' (恕; shù), a 'sense of right and wrong' (耻; chǐ), 'gentleness' (温; wēn), 'kindheartenedness' (良; liáng), 'respect' (恭; gōng), 'frugality' (俭; jiǎn), and 让; ràng; 'modesty').
Ren is the Confucian virtue denoting the good feeling a virtuous human experiences when being altruistic. It is exemplified by a normal adult's protective feelings for children. It is considered the essence of the human being, endowed by Heaven, and at the same time the means by which someone may act according to the principle of Heaven and become one with it.
Yan Hui, Confucius's most outstanding student, once asked his master to describe the rules of ren and Confucius replied, "one should see nothing improper, hear nothing improper, say nothing improper, do nothing improper." Confucius also defined ren in the following way: "wishing to be established himself, seeks also to establish others; wishing to be enlarged himself, he seeks also to enlarge others."
Another meaning of ren is "not to do to others as you would not wish done to yourself." Confucius also said, "ren is not far off; he who seeks it has already found it." Ren is close to man and never leaves him.
Li (礼; 禮) is a word which finds its most extensive use in Confucian and post-Confucian Chinese philosophy. Li is variously translated as 'rite' or 'reason', 'ratio' in the pure sense of Vedic ṛta ('right', 'order') when referring to the cosmic law, but when referring to its realisation in the context of human social behaviour it has also been translated as 'customs', 'measures' and 'rules', among other terms. Li also means religious rites which establish relations between humanity and the gods.
According to Stephan Feuchtwang, rites are conceived as "what makes the invisible visible", making possible for humans to cultivate the underlying order of nature. Correctly performed rituals move society in alignment with earthly and heavenly (astral) forces, establishing the harmony of the three realms—Heaven, Earth and humanity. This practice is defined as "centering" (央; yāng or 中; zhōng). Among all things of creation, humans themselves are "central" because they have the ability to cultivate and centre natural forces.
Li embodies the entire web of interaction between humanity, human objects, and nature. Confucius includes in his discussions of li such diverse topics as learning, tea drinking, titles, mourning, and governance. Xunzi cites "songs and laughter, weeping and lamentation ... rice and millet, fish and meat ... the wearing of ceremonial caps, embroidered robes, and patterned silks, or of fasting clothes and mourning clothes ... spacious rooms and secluded halls, soft mats, couches and benches" as vital parts of the fabric of li.
Confucius envisioned proper government being guided by the principles of li. Some Confucians proposed that all human beings may pursue perfection by learning and practising li. Overall, Confucians believe that governments should place more emphasis on li and rely much less on penal punishment when they govern.
Loyalty (忠; zhōng) is particularly relevant for the social class to which most of Confucius's students belonged, because the most important way for an ambitious young scholar to become a prominent official was to enter a ruler's civil service.
Confucius himself did not propose that "might makes right", but rather that a superior should be obeyed because of his moral rectitude. In addition, loyalty does not mean subservience to authority. This is because reciprocity is demanded from the superior as well. As Confucius stated "a prince should employ his minister according to the rules of propriety; ministers should serve their prince with faithfulness (loyalty)."
Similarly, Mencius also said that "when the prince regards his ministers as his hands and feet, his ministers regard their prince as their belly and heart; when he regards them as his dogs and horses, they regard him as another man; when he regards them as the ground or as grass, they regard him as a robber and an enemy." Moreover, Mencius indicated that if the ruler is incompetent, he should be replaced. If the ruler is evil, then the people have the right to overthrow him. A good Confucian is also expected to remonstrate with his superiors when necessary. At the same time, a proper Confucian ruler should also accept his ministers' advice, as this will help him govern the realm better.
In later ages, however, emphasis was often placed more on the obligations of the ruled to the ruler, and less on the ruler's obligations to the ruled. Like filial piety, loyalty was often subverted by the autocratic regimes in China. Nonetheless, throughout the ages, many Confucians continued to fight against unrighteous superiors and rulers. Many of these Confucians suffered and sometimes died because of their conviction and action. During the Ming-Qing era, prominent Confucians such as Wang Yangming promoted individuality and independent thinking as a counterweight to subservience to authority. The famous thinker Huang Zongxi also strongly criticised the autocratic nature of the imperial system and wanted to keep imperial power in check.
Many Confucians also realised that loyalty and filial piety have the potential of coming into conflict with one another. This may be true especially in times of social chaos, such as during the period of the Ming-Qing transition.
In Confucian philosophy, "filial piety" (孝; xiào) is a virtue of respect for one's parents and ancestors, and of the hierarchies within society: father–son, elder–junior and male–female. The Confucian classic Xiaojing ("Book of Piety"), thought to be written during the Qin or Han dynasties, has historically been the authoritative source on the Confucian tenet of xiao. The book, a conversation between Confucius and his disciple Zeng Shen, is about how to set up a good society using the principle of xiao.
In more general terms, filial piety means to be good to one's parents; to take care of one's parents; to engage in good conduct not just towards parents but also outside the home so as to bring a good name to one's parents and ancestors; to perform the duties of one's job well so as to obtain the material means to support parents as well as carry out sacrifices to the ancestors; not be rebellious; show love, respect and support; the wife in filial piety must obey her husband absolutely and take care of the whole family wholeheartedly. display courtesy; ensure male heirs, uphold fraternity among brothers; wisely advise one's parents, including dissuading them from moral unrighteousness, for blindly following the parents' wishes is not considered to be xiao; display sorrow for their sickness and death; and carry out sacrifices after their death.
Filial piety is considered a key virtue in Chinese culture, and it is the main concern of a large number of stories. One of the most famous collections of such stories is "The Twenty-four Filial Exemplars". These stories depict how children exercised their filial piety in the past. While China has always had a diversity of religious beliefs, filial piety has been common to almost all of them; historian Hugh D.R. Baker calls respect for the family the only element common to almost all Chinese believers.
Social harmony results in part from every individual knowing his or her place in the natural order, and playing his or her part well. Reciprocity or responsibility (renqing) extends beyond filial piety and involves the entire network of social relations, even the respect for rulers. This is shown in the story where Duke Jing of Qi asks Confucius about government, by which he meant proper administration so as to bring social harmony:
齊景公問政於孔子。孔子對曰：君君，臣臣，父父，子子。 The duke Jing, of Qi, asked Confucius about government. Confucius replied, "There is government, when the prince is prince, and the minister is minister; when the father is father, and the son is son."
Particular duties arise from one's particular situation in relation to others. The individual stands simultaneously in several different relationships with different people: as a junior in relation to parents and elders, and as a senior in relation to younger siblings, students, and others. While juniors are considered in Confucianism to owe their seniors reverence, seniors also have duties of benevolence and concern toward juniors. The same is true with the husband and wife relationship where the husband needs to show benevolence towards his wife and the wife needs to respect the husband in return. This theme of mutuality still exists in East Asian cultures even to this day.
The Five Bonds are: ruler to ruled, father to son, husband to wife, elder brother to younger brother, friend to friend. Specific duties were prescribed to each of the participants in these sets of relationships. Such duties are also extended to the dead, where the living stand as sons to their deceased family. The only relationship where respect for elders is not stressed was the friend to friend relationship, where mutual equal respect is emphasised instead. All these duties take the practical form of prescribed rituals, for instance wedding and death rituals.
The junzi ('lord's son') is a Chinese philosophical term often translated as "gentleman" or "superior person" and employed by Confucius in the Analects to describe the ideal man.
In Confucianism, the sage or wise is the ideal personality; however, it is very hard to become one of them. Confucius created the model of junzi, gentleman, which may be achieved by any individual. Later, Zhu Xi defined junzi as second only to the sage. There are many characteristics of the junzi: he may live in poverty, he does more and speaks less, he is loyal, obedient and knowledgeable. The junzi disciplines himself. Ren is fundamental to become a junzi.
As the potential leader of a nation, a son of the ruler is raised to have a superior ethical and moral position while gaining inner peace through his virtue. To Confucius, the junzi sustained the functions of government and social stratification through his ethical values. Despite its literal meaning, any righteous man willing to improve himself may become a junzi.
In contrast to the junzi, the xiaoren (小人; xiăorén, "small or petty person") does not grasp the value of virtues and seeks only immediate gains. The petty person is egotistic and does not consider the consequences of his action in the overall scheme of things. Should the ruler be surrounded by xiaoren as opposed to junzi, his governance and his people will suffer due to their small-mindness. Examples of such xiaoren individuals may range from those who continually indulge in sensual and emotional pleasures all day to the politician who is interested merely in power and fame; neither sincerely aims for the long-term benefit of others.
The junzi enforces his rule over his subjects by acting virtuously himself. It is thought that his pure virtue would lead others to follow his example. The ultimate goal is that the government behaves much like a family, the junzi being a beacon of filial piety.
Confucius believed that social disorder often stemmed from failure to perceive, understand, and deal with reality. Fundamentally, then, social disorder may stem from the failure to call things by their proper names, and his solution to this was the "rectification of names" (正名; zhèngmíng). He gave an explanation of this concept to one of his disciples:
Zi-lu said, "The vassal of Wei has been waiting for you, in order with you to administer the government. What will you consider the first thing to be done?" The Master replied, "What is necessary to rectify names." "So! indeed!" said Zi-lu. "You are wide off the mark! Why must there be such rectification?" The Master said, "How uncultivated you are, Yu! The superior man [Junzi] cannot care about the everything, just as he cannot go to check all himself! If names be not correct, language is not in accordance with the truth of things. If language be not in accordance with the truth of things, affairs cannot be carried on to success. When affairs cannot be carried on to success, proprieties and music do not flourish. When proprieties and music do not flourish, punishments will not be properly awarded. When punishments are not properly awarded, the people do not know how to move hand or foot. Therefore a superior man considers it necessary that the names he uses may be spoken appropriately, and also that what he speaks may be carried out appropriately. What the superior man requires is just that in his words there may be nothing incorrect." (Analects XIII, 3, tr. Legge)
Xunzi chapter (22) "On the Rectification of Names" claims the ancient sage-kings chose names (名; míng) that directly corresponded with actualities (實; shí), but later generations confused terminology, coined new nomenclature, and thus could no longer distinguish right from wrong. Since social harmony is of utmost importance, without the proper rectification of names, society would essentially crumble and "undertakings [would] not [be] completed."
According to He Guanghu, Confucianism may be identified as a continuation of the Shang-Zhou (c. 1600–256 BCE) official religion, or the Chinese aboriginal religion which has lasted uninterrupted for three thousand years. Both the dynasties worshipped a supreme "godhead", called Shangdi ('Highest Deity') or Di by the Shang and Tian ('Heaven') by the Zhou. Shangdi was conceived as the first ancestor of the Shang royal house, an alternate name for him being the "Supreme Progenitor" (上甲; Shàngjiǎ). Shang theology viewed the multiplicity of gods of nature and ancestors as parts of Di. Di manifests as the Wufang Shangdi with the winds (風; fēng) as its cosmic will. With the Zhou dynasty, which overthrew the Shang, the name for the supreme godhead became tian. While the Shang identified Shangdi as their ancestor-god to assert their claim to power by divine right, the Zhou transformed this claim into a legitimacy based on moral power, the Mandate of Heaven. In Zhou theology, Tian had no singular earthly progeny, but bestowed divine favour on virtuous rulers. Zhou kings declared that their victory over the Shang was because they were virtuous and loved their people, while the Shang were tyrants and thus were deprived of power by Tian.
John C. Didier and David Pankenier relate the shapes of both the ancient Chinese characters for Di and Tian to the patterns of stars in the northern skies, either drawn, in Didier's theory by connecting the constellations bracketing the north celestial pole as a square, or in Pankenier's theory by connecting some of the stars which form the constellations of the Big Dipper and broader Ursa Major, and Ursa Minor (Little Dipper). Cultures in other parts of the world have also conceived these stars or constellations as symbols of the origin of things, the supreme godhead, divinity and royal power. The supreme godhead was also identified with the dragon, symbol of unlimited power (qi), of the protean primordial power which embodies both yin and yang in unity, associated to the constellation Draco which winds around the north ecliptic pole, and slithers between the Little and Big Dipper.
By the 6th century BCE, the power of Tian and the symbols that represented it on earth (architecture of cities, temples, altars and ritual vessels, and the Zhou system of rites) became "diffuse" and claimed by different potentates in the Zhou states to legitimise economic, political, and military ambitions. Communication with the divine no longer was an exclusive privilege of the Zhou royal house, but might be bought by anyone able to afford the elaborate ceremonies and the old and new rites required to access the authority of Tian.
Besides the waning Zhou ritual system, what may be defined as 'wild' (野; yě) traditions, or traditions outside of the official system, developed as attempts to access the will of Tian. As central political authority crumbled in the wake of the collapse of the Western Zhou, the population lost faith in the official tradition, which was no longer perceived as an effective way to communicate with Heaven. The traditions of the 'Nine Fields' (九野) and of the Yijing flourished. Chinese thinkers, faced with this challenge to legitimacy, diverged in a "Hundred Schools of Thought", each positing its own philosophical lens for understanding the processes of the world.
Confucius (551–479 BCE) appeared in this period of political reconfiguration and spiritual questioning. He was educated in Shang–Zhou traditions, which he contributed to transmit and reformulate giving centrality to self-cultivation and agency of humans, and the educational power of the self-established individual in assisting others to establish themselves (the 愛人; àirén; 'principle of loving others'). As the Zhou reign collapsed, traditional values were abandoned resulting in a period of perceived moral decline. Confucius saw an opportunity to reinforce values of compassion and tradition into society, with the intended goal of reconstructing what he believed to be a lost perfect moral order of high antiquity. Disillusioned with the culture, opposing scholars, and religious authorities of the time, he began to advance an ethical interpretation of traditional Zhou religion. In his view, the power of Tian is pervasive, and responds positively to the sincere heart driven by humaneness and rightness, decency and altruism. Confucius conceived these qualities as the foundation needed to restore socio-political harmony. Like many contemporaries, Confucius saw ritual practices as efficacious ways to access Tian, but he thought that the crucial knot was the reverent inner state that participants enter prior to engaging in the ritual acts. Confucius is said to have amended and recodified the classical books inherited from the Xia-Shang-Zhou dynasties, and to have composed the Spring and Autumn Annals.
Philosophers in the Warring States period, both focused on state-endorsed ritual and non-aligned to state ritual built upon Confucius's legacy, compiled in the Analects, and formulated the classical metaphysics that became the lash of Confucianism. In accordance with Confucius, they identified mental tranquility as the state of Tian, or 'the One' (一; Yī), which in each individual is the Heaven-bestowed divine power to rule one's own life and the world. They also extended the theory, proposing the oneness of production and reabsorption into the cosmic source, and the possibility to understand and therefore reattain it through correct state of mind. This line of thought would have influenced all Chinese individual and collective-political mystical theories and practices thereafter.
In the Han dynasty, Confucians beginning with Dong Zhongshu synthesised Warring States Confucianism with ideas of yin and yang, and wuxing, as well as folk superstition and the prior schools that led up to the School of Naturalists.
In the 460s, Confucianism competed with Chinese Buddhism and "traditional Confucianism" was "a broad cosmology that was as much about personal ethics as about spiritual beliefs" and had roots that went back to Confucianist philosophers from over a thousand years before.
Since the 2000s, there has been a growing identification of the Chinese intellectual class with Confucianism. In 2003, the Confucian intellectual Kang Xiaoguang published a manifesto in which he made four suggestions: Confucian education should enter official education at any level, from elementary to high school; the state should establish Confucianism as the state religion by law; Confucian religion should enter the daily life of ordinary people through standardisation and development of doctrines, rituals, organisations, churches and activity sites; the Confucian religion should be spread through non-governmental organisations. Another modern proponent of the institutionalisation of Confucianism in a state church is Jiang Qing.
In 2005, the Center for the Study of Confucian Religion was established, and guoxue started to be implemented in public schools on all levels. Being well received by the population, even Confucian preachers have appeared on television since 2006. The most enthusiastic New Confucians proclaim the uniqueness and superiority of Confucian Chinese culture, and have generated some popular sentiment against Western cultural influences in China.
The idea of a "Confucian church" as the state religion of China has roots in the thought of Kang Youwei, an exponent of the early New Confucian search for a regeneration of the social relevance of Confucianism, at a time when it was de-institutionalised with the collapse of the Qing dynasty and the Chinese empire. Kang modeled his ideal "Confucian Church" after European national Christian churches, as a hierarchic and centralised institution, closely bound to the state, with local church branches, devoted to the worship and the spread of the teachings of Confucius.
In contemporary China, the Confucian revival has developed into various interwoven directions: the proliferation of Confucian schools or academies, the resurgence of Confucian rites, and the birth of new forms of Confucian activity on the popular level, such as the Confucian communities (社區儒學; shèqū rúxué). Some scholars also consider the reconstruction of lineage churches and their ancestral temples, as well as cults and temples of natural and national gods within broader Chinese traditional religion, as part of the renewal of Confucianism.
Other forms of revival are salvationist folk religious movements groups with a specifically Confucian focus, or Confucian churches, for example the Yīdān xuétáng (一耽學堂) of Beijing, the Mèngmǔtáng (孟母堂) of Shanghai, Confucian Shenism (also known as the "phoenix churches"), the Confucian Fellowship (儒教道壇; Rújiào Dàotán) in northern Fujian which has spread rapidly over the years after its foundation, and ancestral temples of the Kong kin (the lineage of the descendants of Confucius himself) operating as Confucian-teaching churches.
Also, the Hong Kong Confucian Academy, one of the direct heirs of Kang Youwei's Confucian Church, has expanded its activities to the mainland, with the construction of statues of Confucius, Confucian hospitals, restoration of temples and other activities. In 2009, Zhou Beichen founded another institution which inherits the idea of Kang Youwei's Confucian Church, the Holy Hall of Confucius (孔聖堂; Kǒngshèngtáng) in Shenzhen, affiliated with the Federation of Confucian Culture of Qufu City. It was the first of a nationwide movement of congregations and civil organisations that was unified in 2015 in the Holy Confucian Church. The first spiritual leader of the church is the scholar Jiang Qing, the founder and manager of the Yangming Confucian Abode (陽明精舍; Yángmíng jīngshě), a Confucian academy in Guiyang, Guizhou.
Chinese folk religious temples and kinship ancestral shrines may, on peculiar occasions, choose Confucian liturgy (called 儒; rú or 正統 (zhèngtǒng; 'orthopraxy') led by Confucian ritual masters (禮生; lǐshēng) to worship the gods, instead of Taoist or popular ritual. "Confucian businessmen" (儒商人; rúshāngrén, also "refined businessman") is a recently "rediscovered" concept defining people of the economic-entrepreneurial elite who recognise their social responsibility and therefore apply Confucian culture to their business.
Confucianists historically tried to proselytize to others, although this is rarely done in modern times. Given Confucianism's place of importance in historical Chinese governments, the argument has been made that Imperial China's wars were Confucianism's wars, but the connection between Confucianism and war is not so direct or simple. Modern Confucianism is the descendant of movements that greatly changed how they practiced the teachings of Confucius and his disciples from previous orthodox teachings.
子曰：為政以德，譬如北辰，居其所而眾星共之。 The Master said, "He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn towards it."
A key Confucian concept is that in order to govern others one must first govern oneself according to the universal order. When actual, the king's personal virtue (de) spreads beneficent influence throughout the kingdom. This idea is developed further in the Great Learning and is tightly linked with the Taoist concept of wu wei: the less the king does, the more gets done. By being the "calm center" around which the kingdom turns, the king allows everything to function smoothly and avoids having to tamper with the individual parts of the whole.
This idea may be traced back to the ancient shamanic beliefs of the king being the axle between the sky, human beings, and the Earth. The emperors of China were considered agents of Heaven, endowed with the Mandate of Heaven, one of the most vital concepts in imperial-era political theory. Some Confucianists believed they held the power to define the hierarchy of divinities, by bestowing titles upon mountains, rivers and dead people, acknowledging them as powerful and therefore establishing their cults.
Confucianism, despite supporting the importance of obeying national authority, places this obedience under absolute moral principles that curbed the willful exercise of power, rather than being unconditional. Submission to authority was only taken within the context of the moral obligations that rulers had toward their subjects, in particular ren. Confucians—including the most pro-authoritarian scholars such as Xunzi—have always recognised the right of revolution against tyranny.
子曰：有教無類。 The Master said: "In teaching, there should be no distinction of classes."
Although Confucius claimed that he never invented anything but was only transmitting ancient knowledge (Analects 7.1), he did produce a number of new ideas. Many European and American admirers such as Voltaire and Herrlee G. Creel point to the revolutionary idea of replacing nobility of blood with nobility of virtue. Junzi ('lord's son'), which originally signified the younger, non-inheriting, offspring of a noble, became, in Confucius's work, an epithet having much the same meaning and evolution as the English "gentleman".
A virtuous commoner who cultivates his qualities may be a "gentleman", while a shameless son of the king is only a "petty person". That Confucius admitted students of different classes as disciples is a clear demonstration that he fought against the feudal structures that defined pre-imperial Chinese society.
Another new idea, that of meritocracy, led to the introduction of the imperial examination system in China. This system allowed anyone who passed an examination to become a government officer, a position which would bring wealth and honour to the whole family. The Chinese imperial examination system started in the Sui dynasty. Over the following centuries the system grew until finally almost anyone who wished to become an official had to prove his worth by passing a set of written government examinations.
Confucian political meritocracy is not merely a historical phenomenon. The practice of meritocracy still exists across China and East Asia today, and a wide range of contemporary intellectuals—from Daniel Bell to Tongdong Bai, Joseph Chan, and Jiang Qing—defend political meritocracy as a viable alternative to liberal democracy.
In Just Hierarchy, Daniel Bell and Wang Pei argue that hierarchies are inevitable. Faced with ever-increasing complexity at scale, modern societies must build hierarchies to coordinate collective action and tackle long-term problems such as climate change. In this context, people need not—and should not—want to flatten hierarchies as much as possible. They ought to ask what makes political hierarchies just and use these criteria to decide the institutions that deserve preservation, those that require reform, and those that need radical transformation. They call this approach "progressive conservatism", a term that reflects the ambiguous place of the Confucian tradition within the Left-Right dichotomy.
Bell and Wang propose two justifications for political hierarchies that do not depend on a "one person, one vote" system. First is raw efficiency, which may require centralized rule in the hands of the competent few. Second, and most important, is serving the interests of the people (and the common good more broadly). In Against Political Equality, Tongdong Bai complements this account by using a proto-Rawlsian "political difference principle". Just as Rawls claims that economic inequality is justified so long as it benefits those at the bottom of the socioeconomic ladder, so Bai argues that political inequality is justified so long as it benefits those materially worse off.
Bell, Wang, and Bai all criticize liberal democracy to argue that government by the people may not be government for the people in any meaningful sense of the term. They argue that voters tend to act in irrational, tribal, short-termist ways; they are vulnerable to populism and struggle to account for the interests of future generations. In other words, at a minimum, democracy needs Confucian meritocratic checks.
In The China Model, Bell argues that Confucian political meritocracy provides—and has provided—a blueprint for China's development. For Bell, the ideal according to which China should reform itself (and has reformed itself) follows a simple structure: Aspiring rulers first pass hyper-selective examinations, then have to rule well at the local level to be promoted to positions as the provincial level, then have to excel at the provincial level to access positions at the national level, and so on. This system aligns with what Harvard historian James Hankins calls "virtue politics", or the idea that institutions should be built to select the most competent and virtuous rulers—as opposed to institutions concerned first and foremost with limiting the power of rulers.
While contemporary defenders of Confucian political meritocracy all accept this broad frame, they disagree with each other on three main questions: institutional design, the means by which meritocrats are promoted, and the compatibility of Confucian political meritocracy with liberalism.
Bell and Wang favour a system in which officials at the local level are democratically elected and higher-level officials are promoted by peers. As Bell puts it, he defends "democracy at the bottom, experimentation in the middle, and meritocracy at the top." Bell and Wang argue that this combination conserves the main advantages of democracy—involving the people in public affairs at the local level, strengthening the legitimacy of the system, forcing some degree of direct accountability, etc.—while preserving the broader meritocratic character of the regime.
Jiang Qing, by contrast, imagines a tricameral government with one chamber selected by the people (the 庶民院; 'House of the Commoners'), one chamber composed of Confucian meritocrats selected via examination and gradual promotion (the 通儒院; 'House of Confucian Tradition'), and one body made up of descendants of Confucius himself (the 國體院; 'House of National Essence'). Jiang's aim is to construct a legitimacy that will go beyond what he sees as the atomistic, individualist, and utilitarian ethos of modern democracies and ground authority in something sacred and traditional. While Jiang's model is closer to an ideal theory than Bell's proposals, it represents a more traditionalist alternative.
Tongdong Bai presents an in-between solution by proposing a two-tiered bicameral system. At the local level, as with Bell, Bai advocates Deweyan participatory democracy. At the national level, Bai proposes two chambers: one of meritocrats (selected by examination, by examination and promotion, from leaders in certain professional fields, etc.), and one of representatives elected by the people. While the lower house does not have any legislative power per se, it acts as a popular accountability mechanism by championing the people and putting pressure on the upper house. More generally, Bai argues that his model marries the best of meritocracy and democracy. Following Dewey's account of democracy as a way of life, he points to the participatory features of his local model: citizens still get to have a democratic lifestyle, participate in political affairs, and be educated as "democratic men". Similarly, the lower house allows citizens to be represented, have a voice in public affairs (albeit a weak one), and ensure accountability. Meanwhile, the meritocratic house preserves competence, statesmanship, and Confucian virtues.
Defenders of Confucian political meritocracy generally champion a system in which rulers are selected on the basis of intellect, social skills, and virtue. Bell proposes a model wherein aspiring meritocrats take hyper-selective exams and prove themselves at the local levels of government before reaching the higher levels of government, where they hold more centralized power. In his account, the exams select for intellect and other virtues—for instance, the ability to argue three different viewpoints on a contentious issue may indicate a certain degree of openness. Tongdong Bai's approach incorporates different ways to select members of the meritocratic house, from exams to performance in various fields—business, science, administration, and so on. In every case, Confucian meritocrats draw on China's extensive history of meritocratic administration to outline the pros and cons of competing methods of selection.
For those who, like Bell, defend a model in which performance at the local levels of government determines future promotion, an important question is how the system judges who "performs best". In other words, while examinations may ensure that early-career officials are competent and educated, how is it thereafter ensured that only those who rule well get promoted? The literature opposes those who prefer evaluation by peers to evaluation by superiors, with some thinkers including quasi-democratic selection mechanisms along the way. Bell and Wang favour a system in which officials at the local level are democratically elected and higher-level officials are promoted by peers. Because they believe that promotion should depend upon peer evaluations only, Bell and Wang argue against transparency—i.e. the public should not know how officials are selected, since ordinary people are in no position to judge officials beyond the local level. Others, like Jiang Qing, defend a model in which superiors decide who gets promoted; this method is in line with more traditionalist strands of Confucian political thought, which place a greater emphasis on strict hierarchies and epistemic paternalism—that is, the idea that older and more experienced people know more.
Another key question is whether Confucian political thought is compatible with liberalism. Tongdong Bai, for instance, argues that while Confucian political thought departs from the "one person, one vote" model, it can conserve many of the essential characteristics of liberalism, such as freedom of speech and individual rights. In fact, both Daniel Bell and Tongdong Bai hold that Confucian political meritocracy can tackle challenges that liberalism wants to tackle, but cannot by itself. At the cultural level, for instance, Confucianism, its institutions, and its rituals offer bulwarks against atomization and individualism. At the political level, the non-democratic side of political meritocracy is—for Bell and Bai—more efficient at addressing long-term questions such as climate change, in part because the meritocrats do not have to worry about the whims of public opinion.
Joseph Chan defends the compatibility of Confucianism with both liberalism and democracy. In his book Confucian Perfectionism, he argues that Confucians can embrace both democracy and liberalism on instrumental grounds; that is, while liberal democracy may not be valuable for its own sake, its institutions remain valuable—particularly when combined with a broadly Confucian culture—to serve Confucian ends and inculcate Confucian virtues.
Other Confucians have criticized Confucian meritocrats like Bell for their rejection of democracy. For them, Confucianism does not have to be premised on the assumption that meritorious, virtuous political leadership is inherently incompatible with popular sovereignty, political equality and the right to political participation. These thinkers accuse the meritocrats of overestimating the flaws of democracy, mistaking temporary flaws for permanent and inherent features, and underestimating the challenges that the construction of a true political meritocracy poses in practice—including those faced by contemporary China and Singapore. Franz Mang claims that, when decoupled from democracy, meritocracy tends to deteriorate into an oppressive regime under putatively "meritorious" but actually "authoritarian" rulers; Mang accuses Bell's China model of being self-defeating, as—Mang claims—the CCP's authoritarian modes of engagement with the dissenting voices illustrate. He Baogang and Mark Warren add that "meritocracy" should be understood as a concept describing a regime's character rather than its type, which is determined by distribution of political power—on their view, democratic institutions can be built which are meritocratic insofar as they favour competence.
Roy Tseng, drawing on the New Confucians of the twentieth century, argues that Confucianism and liberal democracy can enter into a dialectical process, in which liberal rights and voting rights are rethought into resolutely modern, but nonetheless Confucian ways of life. This synthesis, blending Confucians rituals and institutions with a broader liberal democratic frame, is distinct from both Western-style liberalism—which, for Tseng, suffers from excessive individualism and a lack of moral vision—and from traditional Confucianism—which, for Tseng, has historically suffered from rigid hierarchies and sclerotic elites. Against defenders of political meritocracy, Tseng claims that the fusion of Confucian and democratic institutions can conserve the best of both worlds, producing a more communal democracy which draws on a rich ethical tradition, addresses abuses of power, and combines popular accountability with a clear attention to the cultivation of virtue in elites.
The works of Confucius were translated into European languages through the agency of Jesuit missionaries stationed in China. Matteo Ricci was among the very earliest to report on the thoughts of Confucius, and father Prospero Intorcetta wrote about the life and works of Confucius in Latin in 1687.
Translations of Confucian texts influenced European thinkers of the period, particularly among the Deists and other philosophical groups of the Enlightenment who were interested by the integration of the system of morality of Confucius into Western civilization.
Confucianism influenced the German philosopher Gottfried Wilhelm Leibniz, who was attracted to the philosophy because of its perceived similarity to his own. It is postulated that certain elements of Leibniz's philosophy, such as "simple substance" and "Pre-established harmony", were borrowed from his interactions with Confucianism.
The French philosopher Voltaire, Leibniz's intellectual rival, was also influenced by Confucius, seeing the concept of Confucian rationalism as an alternative to Christian dogma. He praised Confucian ethics and politics, portraying the sociopolitical hierarchy of China as a model for Europe:
Confucius has no interest in falsehood; he did not pretend to be prophet; he claimed no inspiration; he taught no new religion; he used no delusions; flattered not the emperor under whom he lived ...
From the late 17th century onwards a whole body of literature known as the Han Kitab developed amongst the Hui Muslims of China who infused Islamic thought with Confucianism. Especially the works of Liu Zhi such as Tianfang Dianli (天方典禮; Tiānfāng Diǎnlǐ) sought to harmonise Islam with not only Confucianism but also with Taoism and is considered to be one of the crowning achievements of the Chinese Islamic culture.
Important military and political figures in modern Chinese history continued to be influenced by Confucianism, like the Muslim warlord Ma Fuxiang. The New Life Movement in the early 20th century was also influenced by Confucianism.
Referred to variously as the Confucian hypothesis and as a debated component of the more all-encompassing Asian Development Model, there exists among political scientists and economists a theory that Confucianism plays a large latent role in the ostensibly non-Confucian cultures of modern-day East Asia, in the form of the rigorous work ethic it endowed those cultures with. These scholars have held that, if not for Confucianism's influence on these cultures, many of the people of the East Asia region would not have been able to modernise and industrialise as quickly as Singapore, Malaysia, Hong Kong, Taiwan, Japan, South Korea and even China have done.
For example, the impact of the Vietnam War on Vietnam was devastating, but over the last few decades Vietnam has been re-developing in a very fast pace. Most scholars attribute the origins of this idea to futurologist Herman Kahn's World Economic Development: 1979 and Beyond.
Other studies, for example Cristobal Kay's Why East Asia Overtook Latin America: Agrarian Reform, Industrialization, and Development, have attributed the Asian growth to other factors, for example the character of agrarian reforms, "state-craft" (state capacity), and interaction between agriculture and industry.
Historical and current Confucianists were/are often environmentalists out of their respect for tian and the other aspects of nature and the "Principle" that comes from their unity and, more generally, harmony as a whole, which is "the basis for a sincere mind."
After Confucianism had become the official 'state religion' in China, its influence penetrated all walks of life and all streams of thought in Chinese society for the generations to come. This did not exclude martial arts culture. Though in his own day, Confucius had rejected the practice of Martial Arts (with the exception of Archery), he did serve under rulers who used military power extensively to achieve their goals. In later centuries, Confucianism heavily influenced many educated martial artists of great influence, such as Sun Lutang, especially from the 19th century onwards, when bare-handed martial arts in China became more widespread and had begun to more readily absorb philosophical influences from Confucianism, Buddhism and Daoism.
Confucius and Confucianism were opposed or criticised from the start, including Laozi's philosophy and Mozi's critique, and Legalists such as Han Fei ridiculed the idea that virtue would lead people to be orderly. In modern times, waves of opposition and vilification showed that Confucianism, instead of taking credit for the glories of Chinese civilisation, now had to take blame for its failures. The Taiping Rebellion described Confucianism sages as well as gods in Taoism and Buddhism as devils.
In the New Culture Movement, Lu Xun criticised Confucianism for shaping Chinese people into the condition they had reached by the late Qing dynasty: his criticisms are expressed metaphorically in the work "Diary of a Madman", in which traditional Chinese Confucian society is portrayed as feudalistic, hypocritical, socially cannibalistic, despotic, fostering a "slave mentality" favouring despotism, lack of critical thinking and blind obedience and worship of authority, fuelling a form of "Confucian authoritarianism" which persists into the present day. Leftists during the Cultural Revolution described Confucius as the representative of the slave-owning class.
In South Korea, there has long been criticism. Some South Koreans believe Confucianism has not contributed to the modernisation of South Korea. For example, South Korean writer Kim Kyong-il wrote an essay entitled "Confucius Must Die For the Nation to Live" (공자가 죽어야 나라가 산다, gongjaga jug-eoya naraga sanda). Kim said that filial piety is one-sided and blind, and if it continues, social problems will continue as government keeps forcing Confucian filial obligations onto families.
Confucianism "largely defined the mainstream discourse on gender in China from the Han dynasty onward." The gender roles prescribed in the Three Obediences and Four Virtues became a cornerstone of the family, and thus, societal stability. The Three Obediences and Four Virtues is one of the moral standards for feudal etiquette to bind women. Starting from the Han period, Confucians began to teach that a virtuous woman was supposed to follow the males in her family: the father before her marriage, the husband after she marries, and her sons in widowhood. In the later dynasties, more emphasis was placed on the virtue of chastity. The Song dynasty Confucian Cheng Yi stated that: "To starve to death is a small matter, but to lose one's chastity is a great matter." It was during the Song Dynasty that the value of chastity was so severe, Confucian scholars criminalized the remarriage of widows. widows were revered and memorialised during the Ming and Qing periods.The principle of chaste widowhood was made an official institution during the Ming Dynasty. This "cult of chastity" accordingly condemned many widows to poverty and loneliness by placing a social stigma on remarriage. Though the repercussions for widows at times went beyond poverty and loneliness, as for some the preservation of chastity resulted in suicide. The ideal of a chaste widow became an extremely high honor and esteem, especially for a woman who chose to end her life after her husband’s death. Many instances of such acts were recorded in, Biographies of Virtuous Women, “a collection of stories of women who distinguished themselves by committing suicide after their husband’s deaths to guard their chastity and purity”. Though it can be contested whether all these instances can be deemed self-sacrificing for the virtue of chastity, as it became common practice for women to be forced to commit suicide after their husband’s death. This resulted from the honor which chaste widowhood garnered, lending itself to the husband's family as well as his clan or village.
For years, many modern scholars have regarded Confucianism as a sexist, patriarchal ideology that was historically damaging to Chinese women. It has also been argued by some Chinese and Western writers that the rise of neo-Confucianism during the Song dynasty had led to a decline of status of women. Some critics have also accused the prominent Song neo-Confucian scholar Zhu Xi for believing in the inferiority of women and that men and women need to be kept strictly separate, while Sima Guang also believed that women should remain indoors and not deal with the matters of men in the outside world. Finally, scholars have discussed the attitudes toward women in Confucian texts such as Analects. In a much-discussed passage, women are grouped together with 'small people' (小人), meaning people of low status or low morals) and described as being difficult to cultivate or deal with. Many traditional commentators and modern scholars have debated over the precise meaning of the passage, and whether Confucius referred to all women or just certain groups of women.
Further analysis suggests, however, that women's place in Confucian society may be more complex. During the Han dynasty period, the influential Confucian text Lessons for Women was written by Ban Zhao (45–114 CE) to instruct her daughters how to be proper Confucian wives and mothers, that is, to be silent, hard-working, and compliant. She stresses the complementarity and equal importance of the male and female roles according to yin-yang theory, but she clearly accepts the dominance of the male. However, she does present education and literary power as important for women. In later dynasties, a number of women took advantage of the Confucian acknowledgment of education to become independent in thought.
Joseph A. Adler points out that "Neo-Confucian writings do not necessarily reflect either the prevailing social practices or the scholars' own attitudes and practices in regard to actual women." Matthew Sommers has also indicated that the Qing dynasty government began to realise the utopian nature of enforcing the "cult of chastity" and began to allow practices such as widow remarrying to stand. Moreover, some Confucian texts like Dong Zhongshu's Luxuriant Dew of the Spring and Autumn Annals have passages that suggest a more equal relationship between a husband and his wife. More recently, some scholars have also begun to discuss the viability of constructing a "Confucian feminism".
Ever since Europeans first encountered Confucianism, the issue of how Confucianism should be classified has been subject to debate. In the 16th and the 17th centuries, the earliest European arrivals in China, the Christian Jesuits, considered Confucianism to be an ethical system, not a religion, and one that was compatible with Christianity. The Jesuits, including Matteo Ricci, saw Chinese rituals as "civil rituals" that could co-exist alongside the spiritual rituals of Catholicism.
By the early 18th century, this initial portrayal was rejected by the Dominicans and Franciscans, creating a dispute among Catholics in East Asia that was known as the "Rites Controversy". The Dominicans and Franciscans argued that Chinese ancestral worship was a form of idolatry that was contradictory to the tenets of Christianity. This view was reinforced by Pope Benedict XIV, who ordered a ban on Chinese rituals, though this ban was re-assessed and repealed in 1939 by Pope Pius XII, provided that such traditions harmonize with the true and authentic spirit of the liturgy.
Some critics view Confucianism as definitely pantheistic and nontheistic, in that it is not based on the belief in the supernatural or in a personal god existing separate from the temporal plane. Confucius views about tian and about the divine providence ruling the world, can be found above (in this page) and in Analects 6:26, 7:22, and 9:12, for example. On spirituality, Confucius said to Chi Lu, one of his students: "You are not yet able to serve men, how can you serve spirits?" Attributes such as ancestor worship, ritual, and sacrifice were advocated by Confucius as necessary for social harmony; these attributes may be traced to the traditional Chinese folk religion.
Scholars recognise that classification ultimately depends on how one defines religion. Using stricter definitions of religion, Confucianism has been described as a moral science or philosophy. But using a broader definition, such as Frederick Streng's characterisation of religion as "a means of ultimate transformation", Confucianism could be described as a "sociopolitical doctrine having religious qualities." With the latter definition, Confucianism is religious, even if non-theistic, in the sense that it "performs some of the basic psycho-social functions of full-fledged religions." | [

Confucianism developed from what was later called the Hundred Schools of Thought from the teachings of the Chinese philosopher Confucius (551–479 BCE). Confucius considered himself a transmitter of cultural values inherited from the Xia (c. 2070–1600 BCE), Shang (c. 1600–1046 BCE) and Western Zhou dynasties (c. 1046–771 BCE). Confucianism was suppressed during the Legalist and autocratic Qin dynasty (221–206 BCE), but survived. During the Han dynasty (206 BCE – 220 CE), Confucian approaches edged out the \"proto-Taoist\" Huang–Lao as the official ideology, while the emperors mixed both with the realist techniques of Legalism.",

This reinvigorated form was adopted as the basis of the imperial exams and the core philosophy of the scholar-official class in the Song dynasty (960–1297). The abolition of the examination system in 1905 marked the end of official Confucianism. The intellectuals of the New Culture Movement of the early twentieth century blamed Confucianism for China's weaknesses. They searched for new doctrines to replace Confucian teachings; some of these new ideologies include the \"Three Principles of the People\" with the establishment of the Republic of China, and then Maoism under the People's Republic of China.

While the Confucian concept of tian shares some similarities with the concept of a deity, it is primarily an impersonal absolute principle like the tao or the Brahman.

Shangdi was conceived as the first ancestor of the Shang royal house, an alternate name for him being the \"Supreme Progenitor\" (上甲; Shàngjiǎ). Shang theology viewed the multiplicity of gods of nature and ancestors as parts of Di. Di manifests as the Wufang Shangdi with the winds (風; fēng) as its cosmic will. With the Zhou dynasty, which overthrew the Shang, the name for the supreme godhead became tian. While the Shang identified Shangdi as their ancestor-god to assert their claim to power by divine right, the Zhou transformed this claim into a legitimacy based on moral power, the Mandate of Heaven. In Zhou theology, Tian had no singular earthly progeny, but bestowed divine favour on virtuous rulers.

As the Zhou reign collapsed, traditional values were abandoned resulting in a period of perceived moral decline. Confucius saw an opportunity to reinforce values of compassion and tradition into society, with the intended goal of reconstructing what he believed to be a lost perfect moral order of high antiquity. Disillusioned with the culture, opposing scholars, and religious authorities of the time, he began to advance an ethical interpretation of traditional Zhou religion. In his view, the power of Tian is pervasive, and responds positively to the sincere heart driven by humaneness and rightness, decency and altruism. Confucius conceived these qualities as the foundation needed to restore socio-political harmony. Like many contemporaries, Confucius saw ritual practices as efficacious ways to access Tian, but he thought that the crucial knot was the reverent inner state that participants enter prior to engaging in the ritual acts.

While the lower house does not have any legislative power per se, it acts as a popular accountability mechanism by championing the people and putting pressure on the upper house. More generally, Bai argues that his model marries the best of meritocracy and democracy. Following Dewey's account of democracy as a way of life, he points to the participatory features of his local model: citizens still get to have a democratic lifestyle, participate in political affairs, and be educated as \"democratic men\". Similarly, the lower house allows citizens to be represented, have a voice in public affairs (albeit a weak one), and ensure accountability.

In his account, the exams select for intellect and other virtues—for instance, the ability to argue three different viewpoints on a contentious issue may indicate a certain degree of openness. Tongdong Bai's approach incorporates different ways to select members of the meritocratic house, from exams to performance in various fields—business, science, administration, and so on.

The literature opposes those who prefer evaluation by peers to evaluation by superiors, with some thinkers including quasi-democratic selection mechanisms along the way. Bell and Wang favour a system in which officials at the local level are democratically elected and higher-level officials are promoted by peers. Because they believe that promotion should depend upon peer evaluations only, Bell and Wang argue against transparency—i.e. the public should not know how officials are selected, since ordinary people are in no position to judge officials beyond the local level. Others, like Jiang Qing, defend a model in which superiors decide who gets promoted; this method is in line with more traditionalist strands of Confucian political thought, which place a greater emphasis on strict hierarchies and epistemic paternalism—that is, the idea that older and more experienced people know more.",

Starting from the Han period, Confucians began to teach that a virtuous woman was supposed to follow the males in her family: the father before her marriage, the husband after she marries, and her sons in widowhood. In the later dynasties, more emphasis was placed on the virtue of chastity. The Song dynasty Confucian Cheng Yi stated that: \"To starve to death is a small matter, but to lose one's chastity is a great matter.\" It was during the Song Dynasty that the value of chastity was so severe, Confucian scholars criminalized the remarriage of widows. widows were revered and memorialised during the Ming and Qing periods.The principle of chaste widowhood was made an official institution during the Ming Dynasty. This \"cult of chastity\" accordingly condemned many widows to poverty and loneliness by placing a social stigma on remarriage. Though the repercussions for widows at times went beyond poverty and loneliness, as for some the preservation of chastity resulted in suicide. The ideal of a chaste widow became an extremely high honor and esteem, especially for a woman who chose to end her life after her husband’s death. Many instances of such acts were recorded in, Biographies of Virtuous Women, “a collection of stories of women who distinguished themselves by committing suicide after their husband’s deaths to guard their chastity and purity”. Though it can be contested whether all these instances can be deemed self-sacrificing for the virtue of chastity, as it became common practice for women to be forced to commit suicide after their husband’s death.

] | Confucianism, also known as Ruism or Ru classicism, is a system of thought and behavior originating in ancient China, and is variously described as a tradition, philosophy, religion, theory of government, or way of life. Confucianism developed from what was later called the Hundred Schools of Thought from the teachings of the Chinese philosopher Confucius (551–479 BCE). Confucius considered himself a transmitter of cultural values inherited from the Xia (c. 2070–1600 BCE), Shang (c. 1600–1046 BCE) and Western Zhou dynasties (c. 1046–771 BCE). Confucianism was suppressed during the Legalist and autocratic Qin dynasty (221–206 BCE), but survived. During the Han dynasty, Confucian approaches edged out the "proto-Taoist" Huang–Lao as the official ideology, while the emperors mixed both with the realist techniques of Legalism. Confucianism regards texts such as the Five Classics as examples that should be followed to increase the harmony of the family, social order as a whole, and the world. A Confucian revival began during the Tang dynasty (618–907 CE). In the late Tang, Confucianism developed in response to Buddhism and Taoism and was reformulated as Neo-Confucianism. This reinvigorated form was adopted as the basis of the imperial exams and the core philosophy of the scholar-official class in the Song dynasty (960–1297). The abolition of the examination system in 1905 marked the end of official Confucianism. The intellectuals of the New Culture Movement of the early twentieth century blamed Confucianism for China's weaknesses. They searched for new doctrines to replace Confucian teachings; some of these new ideologies include the "Three Principles of the People" with the establishment of the Republic of China, and then Maoism under the People's Republic of China. In the late twentieth century, the Confucian work ethic has been credited with the rise of the East Asian economy. With particular emphasis on the importance of the family and social harmony, rather than on an otherworldly source of spiritual values, the core of Confucianism is humanistic. According to American philosopher Herbert Fingarette's conceptualisation of Confucianism as a philosophical system which regards "the secular as sacred", Confucianism transcends the dichotomy between religion and humanism, considering the ordinary activities of human life—and especially human relationships—as a manifestation of the sacred, because they are the expression of humanity's moral nature, which has a transcendent anchorage in tian. While the Confucian concept of tian shares some similarities with the concept of a deity, it is primarily an impersonal absolute principle like the tao or the Brahman. Most scholars and practitioners do not think of tian as a god, and the deities that many Confucians worship do not originate from orthodox Confucianism. Confucianism focuses on the practical order that is given by a this-worldly awareness of tian. The worldly concern of Confucianism rests upon the belief that human beings are fundamentally good, and teachable, improvable, and perfectible through personal and communal endeavor, especially self-cultivation and self-creation. Confucian thought focuses on the cultivation of virtue in a morally organised world. Some of the basic Confucian ethical concepts and practices include ren, yi, li, and zhi. Ren is the essence of the human being which manifests as compassion. It is the virtue-form of Heaven. Yi is the upholding of righteousness and the moral disposition to do good. Li is a system of ritual norms and propriety that determines how a person should properly act in everyday life in harmony with the law of Heaven. Zhi is the ability to see what is right and fair, or the converse, in the behaviors exhibited by others. Confucianism holds one in contempt, either passively or actively, for failure to uphold the cardinal moral values of ren and yi. Traditionally, cultures and countries in the East Asian cultural sphere are strongly influenced by Confucianism, including China, Taiwan, Korea, Japan, and Vietnam, as well as various territories settled predominantly by Han Chinese people, such as Singapore and Myanmar's Kokang. Today, it has been credited for shaping East Asian societies and overseas Chinese communities, and to some extent, other parts of Asia. Most Confucianist movements have had significant differences from the original Zhou-era teachings, and are typically much more complex because of their reliance on "elaborate doctrine" and other factors such as traditions with long histories. In the past few decades, there have been talks of a "Confucian Revival" in the academic and the scholarly community, and there has been a grassroots proliferation of various types of Confucian churches. In late 2015, many Confucian personalities formally established a national Confucian Church in China to unify the many Confucian congregations and civil society organisations. | 2001-10-22T02:23:55Z | 2023-12-28T12:37:55Z | [

5,822 | Chinese philosophy | Chinese philosophy originates in the Spring and Autumn period and Warring States period, during a period known as the "Hundred Schools of Thought", which was characterized by significant intellectual and cultural developments. Although much of Chinese philosophy begun in the Warring States period, elements of Chinese philosophy have existed for several thousand years. Some can be found in the I Ching (the Book of Changes), an ancient compendium of divination, which dates back to at least 672 BCE.
It was during the Warring States era that what Sima Tan termed the major philosophical schools of China—Confucianism, Legalism, and Taoism—arose, along with philosophies that later fell into obscurity, like Agriculturalism, Mohism, Chinese Naturalism, and the Logicians. Even in modern society, Confucianism is still the creed of etiquette for Chinese society.
The debate over whether the thought of ancient Chinese masters should be called philosophy has been discussed since the introduction of this academic discipline into China. See Legitimacy of Chinese philosophy for details.
Early Shang dynasty thought was based on cycles like the 10 stems and 12 earthly branches. This notion stems from what the people of the Shang dynasty could observe around them: day and night cycles, the seasons progressed again and again, and even the moon waxed and waned until it waxed again. Thus, this notion, which remained relevant throughout Chinese history, reflects the order of nature. In juxtaposition, it also marks a fundamental distinction from western philosophy, in which the dominant view of time is a linear progression. During the Shang, Ancestor worship was present and universally recognized.
When the Shang were overthrown by the Zhou a new political, religious and philosophical concept was introduced called the Mandate of Heaven. This mandate was said to be taken when rulers became unworthy of their position and provided a justification for Zhou rule it is said that the Duke of Zhou made the early solar terms by measuring with a gnomon that was added to make the complete solar terms. He is also said to have used try squares and wrote the Zhoubi Suanjing with his astrologer. Several early beliefs might be found in the Guicang and perhaps the earliest Chinese book, the small calendar of the Xia in Da Dai Liji, though debated to exist the Xia dynasty is said to be its origin.
Confucianism developed during the Spring and Autumn period from the teachings of the Chinese philosopher Confucius (551–479 BCE), who considered himself a retransmitter of Zhou values. His philosophy concerns the fields of ethics and politics, emphasizing personal and governmental morality, correctness of social relationships, justice, traditionalism, and sincerity. The Analects stress the importance of ritual, but also the importance of ren, which loosely translates as "human-heartedness", Confucianism, along with Legalism, is responsible for creating the world's first meritocracy, which holds that one's status should be determined by education and character rather than ancestry, wealth, or friendship. Confucianism was and continues to be a major influence in Chinese culture, the state of China and the surrounding areas of East Asia.
Before the Han dynasty the largest rivals to Confucianism were Chinese Legalism, and Mohism. Confucianism largely became the dominant philosophical school of China during the early Han dynasty following the replacement of its contemporary, the more Taoist Huang-Lao. Legalism as a coherent philosophy disappeared largely due to its relationship with the unpopular authoritarian rule of Qin Shi Huang, however, many of its ideas and institutions would continue to influence Chinese philosophy throughout the Han dynasty and after.
Mohism, though initially popular due to its emphasis on brotherly love versus harsh Legalism, fell out of favour during the Han dynasty due to the efforts of Confucians in establishing their views as political orthodoxy. The Six Dynasties era saw the rise of the Xuanxue philosophical school and the maturation of Chinese Buddhism, which had entered China from India during the Late Han dynasties. By the time of the Tang dynasty five-hundred years after Buddhism's arrival into China, it had transformed into a thoroughly Chinese religious philosophy dominated by the school of Zen Buddhism. Neo-Confucianism became highly popular during the Song dynasty and Ming dynasty due in large part to the eventual combination of Confucian and Buddhist and even Taoist Philosophy.
During the 19th and 20th centuries, Chinese philosophy integrated concepts from Western philosophy. Anti-Qing dynasty revolutionaries, involved in the Xinhai Revolution, saw Western philosophy as an alternative to traditional philosophical schools; students in the May Fourth Movement called for completely abolishing the old imperial institutions and practices of China. During this era, Chinese scholars attempted to incorporate Western philosophical ideologies such as democracy, Marxism, socialism, liberalism, republicanism, anarchism and nationalism into Chinese philosophy. The most notable examples are Sun Yat-sen's Three Principles of the People ideology and Mao Zedong's Maoism, a variant of Marxism–Leninism. In the modern People's Republic of China, the official ideology is Deng Xiaoping's "market economy socialism".
Although the People's Republic of China has been historically hostile to the philosophy of ancient China, the influences of past are still deeply ingrained in the Chinese culture. In the post-Chinese economic reform era, modern Chinese philosophy has reappeared in forms such as New Confucianism. As in Japan, philosophy in China has become a melting pot of ideas. It accepts new concepts, while attempting also to accord old beliefs their due. Chinese philosophy still carries profound influence amongst the people of East Asia, and even Southeast Asia.
Around 500 BCE, after the Zhou state weakened and China moved into the Spring and Autumn period, the classic period of Chinese philosophy began. This is known as the Hundred Schools of Thought (諸子百家; zhūzǐ bǎijiā; "various scholars, hundred schools"). This period is considered the golden age of Chinese philosophy. Of the many schools founded at this time and during the subsequent Warring States period, the four most influential ones were Confucianism, Daoism (often spelled "Taoism"), Mohism and Legalism.
Confucianism is a philosophical school developed from the teachings of Confucius collected and written by his disciples after his death in The Analects, and in the Warring States period, Mencius in The Mencius and Xunzi in The Xunzi. It is a system of moral, social, political, and religious thought that has had tremendous influence on Chinese history, thought, and culture down to the 20th century. Some Westerners have considered it to have been the "state religion" of imperial China because of its lasting influence on Asian culture. Its influence also spread to Korea, Japan, Vietnam and many other Asian countries.
Confucianism reached its peak of influence during the Tang and Song dynasties under a rebranded Confucianism called Neo-Confucianism. Confucius expanded on the already present ideas of Chinese religion and culture to reflect the time period and environment of political chaos during the Warring States period. Because Confucius embedded the Chinese culture so heavily into his philosophy it was able to resonate with the people of China. This high approval of Confucianism can be seen through the reverence of Confucius in modern-day China.
The major Confucian concepts include filial piety, loyalty (忠; zhōng), li (ritual), ren (humanity or humaneness), the rectification of names (i.e., to ensure everything is what its name implies it should be),. Confucius taught both positive and negative versions of the Golden Rule. The concepts yin and yang represent two opposing forces that are permanently in conflict with each other, leading to perpetual contradiction and change. The Confucian idea of "Rid of the two ends, take the middle" is a Chinese equivalent of the idea of "thesis, antithesis, and synthesis", often attributed to Hegel, which is a way of reconciling opposites, arriving at some middle ground combining the best of both.
Confucius heavily emphasized the idea of microcosms in society (subunits of family and community) success's were the foundations for a successful state or country. Confucius believed in the use of education to further knowledge the people in ethics, societal behavior, and reverence in other humans. With the combination of education, successful family, and his ethical teachings he believed he could govern a well established society in China.
Taoism arose as a philosophy and later also developed into a religion based on the texts the Tao Te Ching (ascribed to Laozi) and the Zhuangzi (partly ascribed to Zhuang Zhou). The word Tao (道; also transliterated as Dao) literally means 'path' or 'way'. However, in Taoism it refers more often to a meta-physical force that encompasses the entire universe but which cannot be described nor felt.
All major Chinese philosophical schools have investigated the correct Way to go about a moral life, but in Taoism it takes on the most abstract meanings, leading this school to be named after it. It advocated nonaction (wu wei), the strength of softness, spontaneity, and relativism. Although it serves as a rival to Confucianism, a school of active morality, this rivalry is compromised and given perspective by the idiom "practice Confucianism on the outside, Taoism on the inside."
Most of Taoism's focus is on the notion that human attempts to make the world better actually make the world worse. Therefore, it is better to strive for harmony, minimising potentially harmful interference with nature or in human affairs.
Philosopher Han Fei synthesized together earlier the methods of his predecessors, which famous historian Sima Tan posthumously termed Legalism. With an essential principle like "when the epoch changed, the ways changed", late pre-Han dynasty reformers emphasized rule by law.
In Han Fei's philosophy, a ruler should govern his subjects by the following trinity:
What has been termed by some as the intrastate Realpolitik of the Warring States period was highly progressive, and extremely critical of the Confucian and Mohist schools. But that of the Qin dynasty would be blamed for creating a totalitarian society, thereby experiencing decline. Its main motto is: "Set clear strict laws, or deliver harsh punishment". In Han Fei's philosophy the ruler possessed authority regarding reward and penalty, enacted through law. Shang Yang and Han Fei promoted absolute adherence to the law, regardless of the circumstances or the person. Ministers were only to be rewarded if their words were accurate to the results of their proposals. Legalism, in accordance with Shang Yang's interpretation, could encourage the state to be a militaristic autarky.
The School of Naturalists or the School of Yin-yang (Chinese: 陰陽家; pinyin: Yīnyángjiā; Wade–Giles: Yin-yang-chia; lit. 'School of Yin-Yang') was a Warring States era philosophy that synthesized the concepts of yin-yang and the wuxing; Zou Yan is considered the founder of this school. His theory attempted to explain the universe in terms of basic forces in nature: the complementary agents of yin (dark, cold, female, negative) and yang (light, hot, male, positive) and the Five Elements or Five Phases (water, fire, wood, metal, and earth).
In its early days, this theory was most strongly associated with the states of Yan and Qi. In later periods, these epistemological theories came to hold significance in both philosophy and popular belief. This school was absorbed into Taoism's alchemic and magical dimensions as well as into the Chinese medical framework. The earliest surviving recordings of this are in the Mawangdui texts and Huangdi Neijing.
Mohism (Moism), founded by Mozi, promotes universal love with the aim of mutual benefit. Everyone must love each other equally and impartially to avoid conflict and war. Mozi was strongly against Confucian ritual, instead emphasizing pragmatic survival through farming, fortification, and statecraft. Tradition is inconsistent, and human beings need an extra-traditional guide to identify which traditions are acceptable. The moral guide must then promote and encourage social behaviors that maximize general benefit. As motivation for his theory, Mozi brought in the Will of Heaven, but rather than being religious his philosophy parallels utilitarianism.
The logicians (School of Names) were concerned with logic, paradoxes, names and actuality (similar to Confucian rectification of names). The logician Hui Shi was a friendly rival to Zhuangzi, arguing against Taoism in a light-hearted and humorous manner. Another logician, Gongsun Long, originated the famous When a White Horse is Not a Horse dialogue.
Agriculturalism was an early agrarian social and political philosophy that advocated peasant utopian communalism and egalitarianism. The philosophy is founded on the notion that human society originates with the development of agriculture, and societies are based upon "people's natural propensity to farm."
The Agriculturalists believed that the ideal government, modeled after the semi-mythical governance of Shennong, is led by a benevolent king, one who works alongside the people in tilling the fields. The Agriculturalist king is not paid by the government through its treasuries; his livelihood is derived from the profits he earns working in the fields, not his leadership. Unlike the Confucians, the Agriculturalists did not believe in the division of labour, arguing instead that the economic policies of a country need to be based upon an egalitarian self sufficiency. The Agriculturalists supported the fixing of prices, in which all similar goods, regardless of differences in quality and demand, are set at exactly the same, unchanging price.
The short founder Qin dynasty, where Legalism was the official philosophy, quashed Mohist and Confucianist schools. Legalism remained influential during the early Han dynasty under the Taoist-Realist ideology Huang-Lao until Emperor Wu of Han adopted Confucianism as official doctrine. Confucianism and Taoism became the determining forces of Chinese thought until the introduction of Buddhism.
Confucianism was particularly strong during the Han dynasty, whose greatest thinker was Dong Zhongshu, who integrated Confucianism with the thoughts of the Zhongshu School and the theory of the Five Elements. He also was a promoter of the New Text school, which considered Confucius as a divine figure and a spiritual ruler of China, who foresaw and started the evolution of the world towards the Universal Peace.
In contrast, there was an Old Text school that advocated the use of Confucian works written in ancient language (from this comes the denomination Old Text) that were so much more reliable. In particular, they refuted the assumption of Confucius as a godlike figure and considered him as the greatest sage, but simply a human and mortal
The 3rd and 4th centuries saw the rise of the Xuanxue (mysterious learning), also called Neo-Taoism.
Buddhism arrived in China around the 1st century AD, but it was not until the Northern and Southern, Sui and Tang dynasties that it gained considerable influence and acknowledgement. At the beginning, it was considered a sort of Taoist sect. Mahayana Buddhism was far more successful in China than its rival Hinayana, and both Indian schools and local Chinese sects arose from the 5th century. Two chiefly important monk philosophers were Sengzhao and Daosheng. But probably the most influential and original of these schools was the Chan sect, which had an even stronger impact in Japan as the Zen sect.
In the mid-Tang Buddhism reached its peak, and reportedly there were 4,600 monasteries, 40,000 hermitages and 260,500 monks and nuns. The power of the Buddhist clergy was so great and the wealth of the monasteries so impressive, that it instigated criticism from Confucian scholars, who considered Buddhism as a foreign religion. In 845 Emperor Wuzong ordered the Great Anti-Buddhist Persecution, confiscating the riches and returning monks and nuns to lay life. From then on, Buddhism lost much of its influence.
Xuanxue was a philosophical school that combined elements of Confucianism and Taoism to reinterpret the I Ching,Tao Te Ching, and Zhuangzi. The most important philosophers of this movement were Wang Bi, Xiang Xiu and Guo Xiang. The main question of this school was whether Being came before Not-Being (in Chinese, ming and wuming). A peculiar feature of these Taoist thinkers, like the Seven Sages of the Bamboo Grove, was the concept of feng liu (lit. wind and flow), a sort of romantic spirit which encouraged following the natural and instinctive impulse.
Buddhism is a religion, a practical philosophy, and arguably a psychology, focusing on the teachings of Gautama Buddha, who lived on the Indian subcontinent most likely from the mid-6th to the early 5th century BCE. When used in a generic sense, a Buddha is generally considered to be someone who discovers the true nature of reality.
Buddhism until the 4th century AD had little impact on China but in the 4th century its teachings hybridized with those of Taoism. Buddhism brought to China the idea of many hells, where sinners went, but the deceased sinners souls could be saved by pious acts. Since Chinese traditional thought focused more on ethics rather than metaphysics, the merging of Buddhist and Taoist concepts developed several schools distinct from the originating Indian schools.
The most prominent examples with philosophical merit are Sanlun, Tiantai, Huayan, and Chan (a.k.a. Zen). They investigate consciousness, levels of truth, whether reality is ultimately empty, and how enlightenment is to be achieved. Buddhism has a spiritual aspect that complements the action of Neo-Confucianism, with prominent Neo-Confucians advocating certain forms of meditation.
Neo-Confucianism was a revived version of old Confucian principles that appeared around the Song dynasty, with Buddhist, Taoist, and Legalist features. The first philosophers, such as Shao Yong, Zhou Dunyi and Chang Zai, were cosmologists and worked on the I Ching. The Cheng brothers, Cheng Yi and Cheng Hao, are considered the founders of the two main schools of thought of Neo-Confucianism: the School of Principle the first, the School of Mind the latter.
The School of Principle gained supremacy during the Song dynasty with the philosophical system elaborated by Zhu Xi, which became mainstream and officially adopted by the government for the imperial examinations under the Yuan dynasty. The School of Mind was developed by Lu Jiuyuan, Zhu Xi's main rival, but was soon forgotten. Only during the Ming dynasty was the School of Mind revived by Wang Shouren, whose influence is equal to that of Zhu Xi. This school was particularly important in Japan.
During the Qing dynasty many philosophers objected against Neo-Confucianism and there was a return to the Han dynasty Confucianism, and also the reprise of the controversy between Old Text and New Text. In this period also started the penetration of Western culture, but most Chinese thought that the Westerners were maybe more advanced in technology and warfare, but that China had primacy in moral and intellectual fields.
Chinese culture was highly influential on the traditions of other East Asian states, and its philosophy directly influenced Korean philosophy, Vietnamese philosophy and Japanese philosophy. During later Chinese dynasties like the Ming Dynasty (1368–1644), as well as in the Korean Joseon dynasty (1392–1897), a resurgent Neo-Confucianism led by thinkers such as Wang Yangming (1472–1529) became the dominant school of thought and was promoted by the imperial state. In Japan, the Tokugawa shogunate (1603–1867) was also strongly influenced by Confucian philosophy.
Despite Confucianism losing popularity to Taoism and Buddhism, Neo-Confucianism combined those ideas into a more metaphysical framework. Its concepts include li (principle, akin to Plato's forms), qi (vital or material force), taiji (the Great Ultimate), and xin (mind). Song dynasty philosopher Zhou Dunyi (1017–1073) is commonly seen as the first true "pioneer" of Neo-Confucianism, using Daoist metaphysics as a framework for his ethical philosophy.
Neo-Confucianism developed both as a renaissance of traditional Confucian ideas, and as a reaction to the ideas of Buddhism and religious Daoism. Although the Neo-Confucianists denounced Buddhist metaphysics, Neo-Confucianism did borrow Daoist and Buddhist terminology and concepts. Neo-Confucianist philosophers like Zhu Xi and Wang Yangming are seen as the most important figures of Neo-Confucianism.
During the Industrial and Modern Ages, Chinese philosophy had also begun to integrate concepts of Western philosophy, as steps toward modernization. Chinese philosophy never developed the concept of human rights, so that classical Chinese lacked words for them. In 1864, W.A.P. Martin had to invent the word quanli (Chinese: 權利) to translate the Western concept of "rights" in the process of translating Henry Wheaton's Elements of International Law into classical Chinese.
By the time of the Xinhai Revolution in 1911, there were many calls such as the May Fourth Movement to completely abolish the old imperial institutions and practices of China. There have been attempts to incorporate democracy, republicanism, and industrialism into Chinese philosophy, notably by Sun Yat-Sen at the beginning of the 20th century. Mao Zedong added Marxism, Stalinism, Chinese Marxist Philosophy and other communist thought.
When the Chinese Communist Party took over the reign, previous schools of thought, excepting notably Legalism, were denounced as backward, and later even purged during the Cultural Revolution, whereas their influences on Chinese thoughts remain until today. The current government of the People's Republic of China is trying to encourage a form of market socialism.
Since the radical movement of the Cultural Revolution, the Chinese government has become much more tolerant with the practice of traditional beliefs. The 1978 Constitution of the People's Republic of China guarantees "freedom of religion" with a number of restrictions. Spiritual and philosophical institutions have been allowed to be established or re-established, as long they are not perceived to be a threat to the power of the CPC. Moreover, those organizations are heavily monitored. The influences of the past are still deeply ingrained in the Chinese culture.
New Confucianism is an intellectual movement of Confucianism that began in the early 20th century in Republican China, and revived in post-Mao era contemporary communist China. It is deeply influenced by, but not identical with, the Neo-Confucianism of the Song and Ming dynasties.
Although the individual philosophical schools differ considerably, they nevertheless share a common vocabulary and set of concerns.

] | Chinese philosophy originates in the Spring and Autumn period and Warring States period, during a period known as the "Hundred Schools of Thought", which was characterized by significant intellectual and cultural developments. Although much of Chinese philosophy begun in the Warring States period, elements of Chinese philosophy have existed for several thousand years. Some can be found in the I Ching, an ancient compendium of divination, which dates back to at least 672 BCE. It was during the Warring States era that what Sima Tan termed the major philosophical schools of China—Confucianism, Legalism, and Taoism—arose, along with philosophies that later fell into obscurity, like Agriculturalism, Mohism, Chinese Naturalism, and the Logicians. Even in modern society, Confucianism is still the creed of etiquette for Chinese society. | 2001-09-02T10:58:04Z | 2023-12-31T22:29:32Z | [

5,823 | Confucius | Kong Qiu (Chinese: 孔丘; c. 551 – c. 479 BCE), generally known as Kongzi (孔子; lit. 'Master Kong') or Kong Fuzi (Chinese: 孔夫子) and commonly Latinized to Confucius, was a Chinese philosopher of the Spring and Autumn period who is traditionally considered the paragon of Chinese sages. Confucius's teachings and philosophy underpin East Asian culture and society, and remain influential across China and East Asia to this day. His philosophical teachings, called Confucianism, emphasized personal and governmental morality, correctness of social relationships, justice, kindness, and sincerity, as well as an emphasis on a ruler's duty to their subjects.
Confucius considered himself a transmitter for the values of earlier periods which he claimed had been abandoned in his time. The time immediately following Confucius's life saw a rich diversity of thought, and was a formative period in China's intellectual history. His ideas gained in prominence during the Warring States period, but experienced setback immediately following the Qin conquest. Under Emperor Wu of Han, Confucius's ideas received official sanction, with affiliated works becoming required reading for one of the career paths to officialdom. During the Tang and Song dynasties, Confucianism developed into a system known in the West as Neo-Confucianism, and later as New Confucianism. Confucianism became part of the Chinese social fabric and way of life.
Confucius is traditionally credited with having authored or edited many of the Chinese classic texts, including all of the Five Classics, but modern scholars are cautious of attributing specific assertions to Confucius himself. At least some of the texts and philosophy he taught were already ancient. Aphorisms concerning his teachings were compiled in the Analects, but only many years after his death.
Confucius's principles have commonality with Chinese tradition and belief. With filial piety, he championed strong family loyalty, ancestor veneration, and respect of elders by their children and of husbands by their wives, recommending family as a basis for ideal government. He espoused the Golden Rule, "Do not do unto others what you do not want done to yourself."
The name "Confucius" is a Latinized form of the Mandarin Chinese Kǒng Fūzǐ (孔夫子, "Master Kong"), and was coined in the late 16th century by early Jesuit missionaries to China. Confucius's family name was Kong (孔, OC:*kʰˤoŋʔ) and his given name was Qiu (丘, OC:*[k]ʷʰə). His courtesy name, a capping (guan: 冠) given at his coming of age ceremony, and by which he would have been known to all but his older family members, was Zhongni (仲尼, OC:*N-truŋ-s nr[əj]), the "Zhòng" indicating that he was the second son in his family.
It is thought that Confucius was born on 28 September 551 BCE, in Zou (鄒, in modern Shandong province). The area was notionally controlled by the kings of Zhou but effectively independent under the local lords of Lu, who ruled from the nearby city of Qufu. His father Kong He (or Shuliang He) was an elderly commandant of the local Lu garrison. His ancestry traced back through the dukes of Song to the Shang dynasty which had preceded the Zhou. Traditional accounts of Confucius's life relate that Kong He's grandfather had migrated the family from Song to Lu. Not all modern scholars accept Confucius's descent from Song nobility.
Kong He died when Confucius was three years old, and Confucius was raised by his mother Yan Zhengzai (顏徵在) in poverty. His mother later died at less than 40 years of age. At age 19, he married Lady Qiguan (亓官氏), and a year later the couple had their first child, their son Kong Li (孔鯉). Qiguan and Confucius later had two daughters together, one of whom is thought to have died as a child and one was named Kong Jiao (孔姣).
Confucius was educated at schools for commoners, where he studied and learned the Six Arts.
Confucius was born into the class of shi (士), between the aristocracy and the common people. He is said to have worked in various government jobs during his early 20s, and as a bookkeeper and a caretaker of sheep and horses, using the proceeds to give his mother a proper burial. When his mother died, Confucius (aged 23) is said to have mourned for three years, as was the tradition.
In Confucius's time, the state of Lu was headed by a ruling ducal house. Under the duke were three aristocratic families, whose heads bore the title of viscount and held hereditary positions in the Lu bureaucracy. The Ji family held the position "Minister over the Masses", who was also the "Prime Minister"; the Meng family held the position "Minister of Works"; and the Shu family held the position "Minister of War". In the winter of 505 BCE, Yang Hu—a retainer of the Ji family—rose up in rebellion and seized power from the Ji family. However, by the summer of 501 BCE, the three hereditary families had succeeded in expelling Yang Hu from Lu. By then, Confucius had built up a considerable reputation through his teachings, while the families came to see the value of proper conduct and righteousness, so they could achieve loyalty to a legitimate government. Thus, that year (501 BCE), Confucius came to be appointed to the minor position of governor of a town. Eventually, he rose to the position of Minister of Crime. It was said in Xunzi that once assuming the post, Confucius ordered the execution of Shaozheng Mao, another Lu state official and scholar whose lectures attracted the three thousand disciples several times except Yan Hui. Shaozheng Mao was accused of 'five crimes', each worth execution, including 'concealed evilness, stubborn abnormality, eloquent duplicity, erudition in bizarre facts and generosity to evildoers'.
Confucius desired to return the authority of the state to the duke by dismantling the fortifications of the city—strongholds belonging to the three families. This way, he could establish a centralized government. However, Confucius relied solely on diplomacy as he had no military authority himself. In 500 BCE, Hou Fan—the governor of Hou—revolted against his lord of the Shu family. Although the Meng and Shu families unsuccessfully besieged Hou, a loyalist official rose up with the people of Hou and forced Hou Fan to flee to the Qi state. The situation may have been in favor for Confucius as this likely made it possible for Confucius and his disciples to convince the aristocratic families to dismantle the fortifications of their cities. Eventually, after a year and a half, Confucius and his disciples succeeded in convincing the Shu family to raze the walls of Hou, the Ji family in razing the walls of Bi, and the Meng family in razing the walls of Cheng. First, the Shu family led an army towards their city Hou and tore down its walls in 498 BCE.
Soon thereafter, Gongshan Furao (also known as Gongshan Buniu), a retainer of the Ji family, revolted and took control of the forces at Bi. He immediately launched an attack and entered the capital Lu. Earlier, Gongshan had approached Confucius to join him, which Confucius considered as he wanted the opportunity to put his principles into practice but he gave up on the idea in the end. Confucius disapproved the use of a violent revolution by principle, even though the Ji family dominated the Lu state by force for generations and had exiled the previous duke. Creel (1949) states that, unlike the rebel Yang Hu before him, Gongshan may have sought to destroy the three hereditary families and restore the power of the duke. However, Dubs (1946) is of the view that Gongshan was encouraged by Viscount Ji Huan to invade the Lu capital in an attempt to avoid dismantling the Bi fortified walls. Whatever the situation may have been, Gongshan was considered an upright man who continued to defend the state of Lu, even after he was forced to flee.
During the revolt by Gongshan, Zhong You had managed to keep the duke and the three viscounts together at the court. Zhong You was one of the disciples of Confucius and Confucius had arranged for him to be given the position of governor by the Ji family. When Confucius heard of the raid, he requested that Viscount Ji Huan allow the duke and his court to retreat to a stronghold on his palace grounds. Thereafter, the heads of the three families and the duke retreated to the Ji's palace complex and ascended the Wuzi Terrace. Confucius ordered two officers to lead an assault against the rebels. At least one of the two officers was a retainer of the Ji family, but they were unable to refuse the orders while in the presence of the duke, viscounts, and court. The rebels were pursued and defeated at Gu. Immediately after the revolt was defeated, the Ji family razed the Bi city walls to the ground.
The attackers retreated after realizing that they would have to become rebels against the state and their lord. Through Confucius' actions, the Bi officials had inadvertently revolted against their own lord, thus forcing Viscount Ji Huan's hand in having to dismantle the walls of Bi (as it could have harbored such rebels) or confess to instigating the event by going against proper conduct and righteousness as an official. Dubs (1949) suggests that the incident brought to light Confucius' foresight, practical political ability, and insight into human character.
When it was time to dismantle the city walls of the Meng family, the governor was reluctant to have his city walls torn down and convinced the head of the Meng family not to do so. The Zuozhuan recalls that the governor advised against razing the walls to the ground as he said that it made Cheng vulnerable to the Qi state and cause the destruction of the Meng family. Even though Viscount Meng Yi gave his word not to interfere with an attempt, he went back on his earlier promise to dismantle the walls.
Later in 498 BCE, Duke Ding personally went with an army to lay siege to Cheng in an attempt to raze its walls to the ground, but he did not succeed. Thus, Confucius could not achieve the idealistic reforms that he wanted including restoration of the legitimate rule of the duke. He had made powerful enemies within the state, especially with Viscount Ji Huan, due to his successes so far. According to accounts in the Zuozhuan and Shiji, Confucius departed his homeland in 497 BCE after his support for the failed attempt of dismantling the fortified city walls of the powerful Ji, Meng, and Shu families. He left the state of Lu without resigning, remaining in self-exile and unable to return as long as Viscount Ji Huan was alive.
The Shiji stated that the neighboring Qi state was worried that Lu was becoming too powerful while Confucius was involved in the government of the Lu state. According to this account, Qi decided to sabotage Lu's reforms by sending 100 good horses and 80 beautiful dancing girls to the duke of Lu. The duke indulged himself in pleasure and did not attend to official duties for three days. Confucius was disappointed and resolved to leave Lu and seek better opportunities, yet to leave at once would expose the misbehavior of the duke and therefore bring public humiliation to the ruler Confucius was serving. Confucius therefore waited for the duke to make a lesser mistake. Soon after, the duke neglected to send to Confucius a portion of the sacrificial meat that was his due according to custom, and Confucius seized upon this pretext to leave both his post and the Lu state.
After Confucius's resignation, he travelled around the principality states of north-east and central China including Wey, Song, Zheng, Cao, Chu, Qi, Chen, and Cai (and a failed attempt to go to Jin). At the courts of these states, he expounded his political beliefs but did not see them implemented.
According to the Zuozhuan, Confucius returned home to his native Lu when he was 68, after he was invited to do so by Ji Kangzi, the chief minister of Lu. The Analects depict him spending his last years teaching 72 or 77 disciples and transmitting the old wisdom via a set of texts called the Five Classics.
During his return, Confucius sometimes acted as an advisor to several government officials in Lu, including Ji Kangzi, on matters including governance and crime.
Burdened by the loss of both his son and his favorite disciples, he died at the age of 71 or 72 from natural causes. Confucius was buried in Kong Lin cemetery which lies in the historical part of Qufu in the Shandong Province. The original tomb erected there in memory of Confucius on the bank of the Sishui River had the shape of an axe. In addition, it has a raised brick platform at the front of the memorial for offerings such as sandalwood incense and fruit.
In the Analects, Confucius presents himself as a "transmitter who invented nothing". He puts the greatest emphasis on the importance of study, and it is the Chinese character for study (學) that opens the text. Far from trying to build a systematic or formalist theory, he wanted his disciples to master and internalize older classics, so that their deep thought and thorough study would allow them to relate the moral problems of the present to past political events (as recorded in the Annals) or the past expressions of commoners' feelings and noblemen's reflections (as in the poems of the Book of Odes).
Although some Chinese people follow Confucianism in a religious manner, many argue that its values are secular and that it is less a religion than a secular morality. Proponents of religious Confucianism argue that despite the secular nature of Confucianism's teachings, it is based on a worldview that is religious. Confucianism discusses elements of the afterlife and views concerning Heaven, but it is relatively unconcerned with some spiritual matters often considered essential to religious thought, such as the nature of souls.
One of the deepest teachings of Confucius may have been the superiority of personal exemplification over explicit rules of behavior. His moral teachings emphasized self-cultivation, emulation of moral exemplars, and the attainment of skilled judgment rather than knowledge of rules. Confucian ethics may, therefore, be considered a type of virtue ethics. His teachings rarely rely on reasoned argument, and ethical ideals and methods are conveyed indirectly, through allusion, innuendo, and even tautology. His teachings require examination and context to be understood. A good example is found in this famous anecdote:
廄焚。子退朝，曰：傷人乎？不問馬。
When the stables were burnt down, on returning from court Confucius said, "Was anyone hurt?" He did not ask about the horses.
By not asking about the horses, Confucius demonstrates that the sage values human beings over property (which animals seem to represent in this example); readers are led to reflect on whether their response would follow Confucius's and to pursue self-improvement if it would not have.
One of his teachings was a variant of the Golden Rule, sometimes called the "Silver Rule" owing to its negative form:
子貢問曰：有一言而可以終身行之者乎？子曰：其恕乎！己所不欲、勿施於人。
Zi Gong [a disciple] asked: "Is there any one word that could guide a person throughout life?" The Master replied: "How about 'reciprocity'! Never impose on others what you would not choose for yourself."
Often overlooked in Confucian ethics are the virtues to the self: sincerity and the cultivation of knowledge. Virtuous action towards others begins with virtuous and sincere thought, which begins with knowledge. A virtuous disposition without knowledge is susceptible to corruption, and virtuous action without sincerity is not true righteousness. Cultivating knowledge and sincerity is also important for one's own sake; the superior person loves learning for the sake of learning and righteousness for the sake of righteousness.
The Confucian theory of ethics as exemplified in lǐ (禮) is based on three important conceptual aspects of life: (a) ceremonies associated with sacrifice to ancestors and deities of various types, (b) social and political institutions, and (c) the etiquette of daily behavior. Some believed that lǐ originated from the heavens, but Confucius stressed the development of lǐ through the actions of sage leaders in human history. His discussions of lǐ seem to redefine the term to refer to all actions committed by a person to build the ideal society, rather than those conforming with canonical standards of ceremony.
In the early Confucian tradition, lǐ was doing the proper thing at the proper time; balancing between maintaining existing norms to perpetuate an ethical social fabric, and violating them in order to accomplish ethical good. Training in the lǐ of past sages, cultivates virtues in people that include ethical judgment about when lǐ must be adapted in light of situational contexts.
In Confucianism, the concept of li is closely related to yì (義), which is based upon the idea of reciprocity. Yì can be translated as righteousness, though it may mean what is ethically best to do in a certain context. The term contrasts with action done out of self-interest. While pursuing one's own self-interest is not necessarily bad, one would be a better, more righteous person if one's life was based upon following a path designed to enhance the greater good. Thus an outcome of yì is doing the right thing for the right reason.
Just as action according to lǐ should be adapted to conform to the aspiration of adhering to yì, so yì is linked to the core value of rén (仁). Rén consists of five basic virtues: seriousness, generosity, sincerity, diligence, and kindness. Rén is the virtue of perfectly fulfilling one's responsibilities toward others, most often translated as "benevolence", "humaneness", or "empathy"; translator Arthur Waley calls it "Goodness" (with a capital G), and other translations that have been put forth include "authoritativeness" and "selflessness". Confucius's moral system was based upon empathy and understanding others, rather than divinely ordained rules. To develop one's spontaneous responses of rén so that these could guide action intuitively was even better than living by the rules of yì. Confucius asserts that virtue is a mean between extremes. For example, the properly generous person gives the right amount – not too much and not too little.
Confucius's political thought is based upon his ethical thought. He argued that the best government is one that rules through "rites" (lǐ) and people's natural morality, and not by using bribery and coercion. He explained that this is one of the most important analects: "If the people be led by laws, and uniformity sought to be given them by punishments, they will try to avoid the punishment, but have no sense of shame. If they be led by virtue, and uniformity sought to be given them by the rules of propriety, they will have the sense of the shame, and moreover will become good." (Analects 2.3, tr. Legge). This "sense of shame" is an internalisation of duty, where the punishment precedes the evil action, instead of following it in the form of laws as in Legalism.
Confucius looked nostalgically upon earlier days, and urged the Chinese, particularly those with political power, to model themselves on earlier examples. In times of division, chaos, and endless wars between feudal states, he wanted to restore the Mandate of Heaven (天命) that could unify the "world" (天下, "all under Heaven") and bestow peace and prosperity on the people. Because his vision of personal and social perfections was framed as a revival of the ordered society of earlier times, Confucius is often considered a great proponent of conservatism, but a closer look at what he proposes often shows that he used (and perhaps twisted) past institutions and rites to push a new political agenda of his own: a revival of a unified royal state, whose rulers would succeed to power on the basis of their moral merits instead of lineage. These would be rulers devoted to their people, striving for personal and social perfection, and such a ruler would spread his own virtues to the people instead of imposing proper behavior with laws and rules.
While Confucius supported the idea of government ruling by a virtuous king, his ideas contained a number of elements to limit the power of rulers. He argued for representing truth in language, and honesty was of paramount importance. Even in facial expression, truth must always be represented. Confucius believed that if a ruler is to lead correctly, by action, that orders would be unnecessary in that others will follow the proper actions of their ruler. In discussing the relationship between a king and his subject (or a father and his son), he underlined the need to give due respect to superiors. This demanded that the subordinates must advise their superiors if the superiors are considered to be taking a course of action that is wrong. Confucius believed in ruling by example, if you lead correctly, orders by force or punishment are not necessary.
Confucius heavily promoted the use of music with rituals or the rites order. The scholar Li Zehou argued that Confucianism is based on the idea of rites. Rites serve as the starting point for each individual and that these sacred social functions allow each person's human nature to be harmonious with reality. Given this, Confucius believed that "music is the harmonization of heaven and earth; the rites is the order of heaven and earth". Thus the application of music in rites creates the order that makes it possible for society to prosper. poetry,
The Confucian approach to music was heavily inspired by the Shijing and the Classic of Music, which was said to be the sixth Confucian classic until it was lost during the Han dynasty. The Shijing serves as one of the current Confucian classics and is a book on poetry that contains a diversified variety of poems as well as folk songs. Confucius is traditionally ascribed with compiling these classics within his school. In the Analects, Confucius described the importance of the art in the development of society:
The Master said, "My children, why do you not study the Book of Poetry? "The Odes serve to stimulate the mind. "They may be used for purposes of self-contemplation. "They teach the art of sociability. "They show how to regulate feelings of resentment. "From them you learn the more immediate duty of serving one's father, and the remoter one of serving one's prince. "From them we become largely acquainted with the names of birds, beasts, and plants."
Confucius's teachings were later turned into an elaborate set of rules and practices by his numerous disciples and followers, who organized his teachings into the Analects. Confucius's disciples and his only grandson, Zisi, continued his philosophical school after his death. These efforts spread Confucian ideals to students who then became officials in many of the royal courts in China, thereby giving Confucianism the first wide-scale test of its dogma.
Two of Confucius's most famous later followers emphasized radically different aspects of his teachings. In the centuries after his death, Mencius (孟子) and Xunzi (荀子) both composed important teachings elaborating in different ways on the fundamental ideas associated with Confucius. Mencius (4th century BCE) articulated the innate goodness in human beings as a source of the ethical intuitions that guide people towards rén, yì, and lǐ, while Xunzi (3rd century BCE) underscored the realistic and materialistic aspects of Confucian thought, stressing that morality was inculcated in society through tradition and in individuals through training. In time, their writings, together with the Analects and other core texts came to constitute the philosophical corpus of Confucianism.
This realignment in Confucian thought was parallel to the development of Legalism, which saw filial piety as self-interest and not a useful tool for a ruler to create an effective state. A disagreement between these two political philosophies came to a head in 223 BCE when the Qin state conquered all of China. Li Si, Prime Minister of the Qin dynasty, convinced Qin Shi Huang to abandon the Confucians' recommendation of awarding fiefs akin to the Zhou dynasty before them which he saw as being against to the Legalist idea of centralizing the state around the ruler. When the Confucian advisers pressed their point, Li Si had many Confucian scholars killed and their books burned—considered a huge blow to the philosophy and Chinese scholarship.
Under the succeeding Han and Tang dynasties, Confucian ideas gained even more widespread prominence. Under Wudi, the works attributed to Confucius were made the official imperial philosophy and required reading for civil service examinations in 140 BCE which was continued nearly unbroken until the end of the 19th century. As Mohism lost support by the time of the Han, the main philosophical contenders were Legalism, which Confucian thought somewhat absorbed, the teachings of Laozi, whose focus on more spiritual ideas kept it from direct conflict with Confucianism, and the new Buddhist religion, which gained acceptance during the Southern and Northern Dynasties era. Both Confucian ideas and Confucian-trained officials were relied upon in the Ming dynasty and even the Yuan dynasty, although Kublai Khan distrusted handing over provincial control to them.
During the Song dynasty, the scholar Zhu Xi (1130–1200 CE) added ideas from Daoism and Buddhism into Confucianism. In his life, Zhu Xi was largely ignored, but not long after his death, his ideas became the new orthodox view of what Confucian texts actually meant. Modern historians view Zhu Xi as having created something rather different and call his way of thinking Neo-Confucianism. Neo-Confucianism held sway in China, Japan, Korea, and Vietnam until the 19th century.
The works of Confucius were first translated into European languages by Jesuit missionaries in the 16th century during the late Ming dynasty. The first known effort was by Michele Ruggieri, who returned to Italy in 1588 and carried on his translations while residing in Salerno. Matteo Ricci started to report on the thoughts of Confucius, and a team of Jesuits—Prospero Intorcetta, Philippe Couplet, and two others—published a translation of several Confucian works and an overview of Chinese history in Paris in 1687. François Noël, after failing to persuade Clement XI that Chinese veneration of ancestors and Confucius did not constitute idolatry, completed the Confucian canon at Prague in 1711, with more scholarly treatments of the other works and the first translation of the collected works of Mencius. It is thought that such works had considerable importance on European thinkers of the period, particularly among the Deists and other philosophical groups of the Enlightenment who were interested by the integration of the system of morality of Confucius into Western civilization.
In the modern era Confucian movements, such as New Confucianism, still exist, but during the Cultural Revolution, Confucianism was frequently attacked by leading figures in the Chinese Communist Party. This was partially a continuation of the condemnations of Confucianism by intellectuals and activists in the early 20th century as a cause of the ethnocentric close-mindedness and refusal of the Qing dynasty to modernize that led to the tragedies that befell China in the 19th century.
Confucius's works are studied by scholars in many other Asian countries, particularly those in the Chinese cultural sphere, such as Korea, Japan, and Vietnam. Many of those countries still hold the traditional memorial ceremony every year.
Among Tibetans, Confucius is often worshipped as a holy king and master of magic, divination and astrology. Tibetan Buddhists see him as learning divination from the Buddha Manjushri (and that knowledge subsequently reaching Tibet through Princess Wencheng), while Bon practitioners see him as being a reincarnation of Tonpa Shenrab Miwoche, the legendary founder of Bon.
The Ahmadiyya Muslim Community believes Confucius was a Divine Prophet of God, as were Lao-Tzu and other eminent Chinese personages.
According to the Siddhar tradition of Tamil Nadu, Confucius is one of the 18 esteemed Siddhars of yore, and is better known as Kalangi Nathar or Kamalamuni. The Thyagaraja Temple in Thiruvarur, Tamil Nadu is home to his Jeeva Samadhi.
In modern times, Asteroid 7853, "Confucius", was named after the Chinese thinker.
Confucius began teaching after he turned 30, and taught more than 3,000 students in his life, about 70 of whom were considered outstanding. His disciples and the early Confucian community they formed became the most influential intellectual force in the Warring States period. The Han dynasty historian Sima Qian dedicated a chapter in his Records of the Grand Historian to the biographies of Confucius's disciples, accounting for the influence they exerted in their time and afterward. Sima Qian recorded the names of 77 disciples in his collective biography, while Kongzi Jiayu, another early source, records 76, not completely overlapping. The two sources together yield the names of 96 disciples. Twenty-two of them are mentioned in the Analects, while the Mencius records 24.
Confucius did not charge any tuition, and only requested a symbolic gift of a bundle of dried meat from any prospective student. According to his disciple Zigong, his master treated students like doctors treated patients and did not turn anybody away. Most of them came from Lu, Confucius's home state, with 43 recorded, but he accepted students from all over China, with six from the state of Wey (such as Zigong), three from Qin, two each from Chen and Qi, and one each from Cai, Chu, and Song. Confucius considered his students' personal background irrelevant, and accepted noblemen, commoners, and even former criminals such as Yan Zhuoju and Gongye Chang. His disciples from richer families would pay a sum commensurate with their wealth which was considered a ritual donation.
Confucius's favorite disciple was Yan Hui, most probably one of the most impoverished of them all. Sima Niu, in contrast to Yan Hui, was from a hereditary noble family hailing from the Song state. Under Confucius's teachings, the disciples became well learned in the principles and methods of government. He often engaged in discussion and debate with his students and gave high importance to their studies in history, poetry, and ritual. Confucius advocated loyalty to principle rather than to individual acumen, in which reform was to be achieved by persuasion rather than violence. Even though Confucius denounced them for their practices, the aristocracy was likely attracted to the idea of having trustworthy officials who were studied in morals as the circumstances of the time made it desirable. In fact, the disciple Zilu even died defending his ruler in Wey.
Yang Hu, who was a subordinate of the Ji family, had dominated the Lu government from 505 to 502 and even attempted a coup, which narrowly failed. As a likely consequence, it was after this that the first disciples of Confucius were appointed to government positions. A few of Confucius's disciples went on to attain official positions of some importance, some of which were arranged by Confucius. By the time Confucius was 50 years old, the Ji family had consolidated their power in the Lu state over the ruling ducal house. Even though the Ji family had practices with which Confucius disagreed and disapproved, they nonetheless gave Confucius's disciples many opportunities for employment. Confucius continued to remind his disciples to stay true to their principles and renounced those who did not, all the while being openly critical of the Ji family.
The influence of Confucius has been observed on multiple Western thinkers, including Niels Bohr, Benjamin Franklin, Allen Ginsberg, Thomas Jefferson, Gottfried Wilhelm Leibniz, Robert Cummings Neville, Alexander Pope, Ezra Pound, François Quesnay, Friedrich Schiller, Voltaire, and Christian Wolff.
No contemporary painting or sculpture of Confucius survives, and it was only during the Han dynasty that he was portrayed visually. Carvings often depict his legendary meeting with Laozi. Since that time there have been many portraits of Confucius as the ideal philosopher. An early verbal portrayal of Confucius is found in the chapter "External Things" (外物; Wàiwù) of the book Zhuangzi (莊子; Zhuāngzǐ), finished in about 3rd BCE, long after Confucius's death. The oldest known portrait of Confucius has been unearthed in the tomb of the Han dynasty ruler Marquis of Haihun (died 59 BCE). The picture was painted on the wooden frame to a polished bronze mirror.
In former times, it was customary to have a portrait in Confucius Temples; however, during the reign of Hongwu Emperor (Taizu) of the Ming dynasty, it was decided that the only proper portrait of Confucius should be in the temple in his home town, Qufu in Shandong. In other temples, Confucius is represented by a memorial tablet. In 2006, the China Confucius Foundation commissioned a standard portrait of Confucius based on the Tang dynasty portrait by Wu Daozi.
The South Wall Frieze in the courtroom of the Supreme Court of the United States depicts Confucius as a teacher of harmony, learning, and virtue.
There have been two film adaptations of Confucius' life: the 1940 film Confucius starring Tang Huaiqiu, and the 2010 film Confucius starring Chow Yun-fat.
Soon after Confucius's death, Qufu, his home town, became a place of devotion and remembrance. The Han dynasty Records of the Grand Historian records that it had already become a place of pilgrimage for ministers. It is still a major destination for cultural tourism, and many people visit his grave and the surrounding temples. In Sinic cultures, there are many temples where representations of the Buddha, Laozi, and Confucius are found together. There are also many temples dedicated to him, which have been used for Confucian ceremonies.
Followers of Confucianism have a tradition of holding spectacular memorial ceremonies of Confucius (祭孔) every year, using ceremonies that supposedly derived from Zhou Li (周禮) as recorded by Confucius, on the date of Confucius's birth. In the 20th century, this tradition was interrupted for several decades in mainland China, where the official stance of the Communist Party and the State was that Confucius and Confucianism represented reactionary feudalist beliefs which held that the subservience of the people to the aristocracy is a part of the natural order. All such ceremonies and rites were therefore banned. Only after the 1990s did the ceremony resume. As it is now considered a veneration of Chinese history and tradition, even Communist Party members may be found in attendance.
In Taiwan, where the Nationalist Party (Kuomintang) strongly promoted Confucian beliefs in ethics and behavior, the tradition of the memorial ceremony of Confucius (祭孔) is supported by the government and has continued without interruption. While not a national holiday, it does appear on all printed calendars, much as Father's Day or Christmas Day do in the Western world.
In South Korea, a grand-scale memorial ceremony called Seokjeon Daeje is held twice a year on Confucius's birthday and the anniversary of his death, at Confucian academies across the country and Sungkyunkwan in Seoul.
Confucius's descendants were repeatedly identified and honored by successive imperial governments with titles of nobility and official posts. They were honored with the rank of a marquis 35 times since Gaozu of the Han dynasty, and they were promoted to the rank of duke 42 times from the Tang dynasty to the Qing dynasty. Emperor Xuanzong of Tang first bestowed the title of "Duke Wenxuan" on Kong Suizhi of the 35th generation. In 1055, Emperor Renzong of Song first bestowed the title of "Duke Yansheng" on Kong Zongyuan of the 46th generation.
During the Southern Song dynasty, the Duke Yansheng Kong Duanyou fled south with the Song Emperor to Quzhou in Zhejiang, while the newly established Jin dynasty (1115–1234) in the north appointed Kong Duanyou's brother Kong Duancao who remained in Qufu as Duke Yansheng. From that time up until the Yuan dynasty, there were two Duke Yanshengs, one in the north in Qufu and the other in the south at Quzhou. An invitation to come back to Qufu was extended to the southern Duke Yansheng Kong Zhu by the Yuan-dynasty Emperor Kublai Khan. The title was taken away from the southern branch after Kong Zhu rejected the invitation, so the northern branch of the family kept the title of Duke Yansheng. The southern branch remained in Quzhou where they live to this day. Confucius's descendants in Quzhou alone number 30,000. The Hanlin Academy rank of Wujing boshi 五經博士 was awarded to the southern branch at Quzhou by a Ming Emperor while the northern branch at Qufu held the title Duke Yansheng. The leader of the southern branch was 孔祥楷 Kong Xiangkai.
In 1351, during the reign of Emperor Toghon Temür of the Yuan dynasty, 54th-generation Kong Shao (孔昭) moved from China to Korea during the Goryeo dynasty, and was received courteously by Princess Noguk (the Mongolian-born queen consort of the future king Gongmin). After being naturalized as a subject of Goryeo, he changed the hanja of his name from "昭" to "紹" (both pronounced so in Korean), married a Korean woman and bore a son (Gong Yeo (Korean: 공여; Hanja: 孔帤), 1329–1397), therefore establishing the Changwon Gong clan (Korean: 창원 공씨; Hanja: 昌原 孔氏), whose ancestral seat was located in Changwon, South Gyeongsang Province. In 1794, during the reign of King Jeongjo, the clan then changed its name to Gokbu Gong clan (Korean: 곡부 공씨; Hanja: 曲阜 孔氏) in honor of Confucius's birthplace Qufu (Korean: 곡부; Hanja: 曲阜; RR: Gokbu).
Famous descendants include actors such as Gong Yoo (real name Gong Ji-cheol (공지철)) and Gong Hyo-jin (공효진); and artists such as male idol group B1A4 member Gongchan (real name Gong Chan-sik (공찬식)), singer-songwriter Minzy (real name Gong Min-ji (공민지)), as well as her great aunt, traditional folk dancer Gong Ok-jin [ko] (공옥진).
Despite repeated dynastic change in China, the title of Duke Yansheng was bestowed upon successive generations of descendants until it was abolished by the Nationalist government in 1935. The last holder of the title, Kung Te-cheng of the 77th generation, was appointed Sacrificial Official to Confucius. Kung Te-cheng died in October 2008, and his son, Kung Wei-yi, the 78th lineal descendant, died in 1989. Kung Te-cheng's grandson, Kung Tsui-chang, the 79th lineal descendant, was born in 1975; his great-grandson, Kung Yu-jen, the 80th lineal descendant, was born in Taipei on 1 January 2006. Te-cheng's sister, Kong Demao, lives in mainland China and has written a book about her experiences growing up at the family estate in Qufu. Another sister, Kong Deqi, died as a young woman. Many descendants of Confucius still live in Qufu today.
A descendant of Confucius, H. H. Kung, was the Premier of the Republic of China. One of his sons, Kong Lingjie [zh] (孔令傑), married Debra Paget who gave birth to Gregory Kung (孔德基).
Confucius's family, the Kongs, have the longest recorded extant pedigree in the world today. The father-to-son family tree, now in its 83rd generation, has been recorded since the death of Confucius. According to the Confucius Genealogy Compilation Committee (CGCC), he has two million known and registered descendants, and there are an estimated three million in all. Of these, several tens of thousands live outside of China. In the 14th century, a Kong descendant went to Korea, where an estimated 34,000 descendants of Confucius live today. One of the main lineages fled from the Kong ancestral home in Qufu during the Chinese Civil War in the 1940s and eventually settled in Taiwan. There are also branches of the Kong family who have converted to Islam after marrying Muslim women, in Dachuan in Gansu province in the 1800s, and in 1715 in Xuanwei in Yunnan province. Many of the Muslim Confucius descendants are descended from the marriage of Ma Jiaga (馬甲尕), a Muslim woman, and Kong Yanrong (孔彥嶸), 59th generation descendant of Confucius in the year 1480, and are found among the Hui and Dongxiang peoples. The new genealogy includes the Muslims. Kong Dejun (孔德軍) is a prominent Islamic scholar and Arabist from Qinghai province and a 77th generation descendant of Confucius.
Because of the huge interest in the Confucius family tree, there was a project in China to test the DNA of known family members of the collateral branches in mainland China. Among other things, this would allow scientists to identify a common Y chromosome in male descendants of Confucius. If the descent were truly unbroken, father-to-son, since Confucius's lifetime, the males in the family would all have the same Y chromosome as their direct male ancestor, with slight mutations due to the passage of time. The aim of the genetic test was to help members of collateral branches in China who lost their genealogical records to prove their descent. However, in 2009, many of the collateral branches decided not to agree to DNA testing. Bryan Sykes, professor of genetics at Oxford University, understands this decision: "The Confucius family tree has an enormous cultural significance ... It's not just a scientific question." The DNA testing was originally proposed to add new members, many of whose family record books were lost during 20th century upheavals, to the Confucian family tree. The main branch of the family which fled to Taiwan was never involved in the proposed DNA test at all.
In 2013, a DNA test performed on multiple different families who claimed descent from Confucius found that they shared the same Y chromosome as reported by Fudan University.
The fifth and most recent edition of the Confucius genealogy was printed by the CGCC. It was unveiled in a ceremony at Qufu on 24 September 2009. Women are now included for the first time.

Confucius's teachings and philosophy underpin East Asian culture and society, and remain influential across China and East Asia to this day. His philosophical teachings, called Confucianism, emphasized personal and governmental morality, correctness of social relationships, justice, kindness, and sincerity, as well as an emphasis on a ruler's duty to their subjects.",

"text": "In Confucius's time, the state of Lu was headed by a ruling ducal house. Under the duke were three aristocratic families, whose heads bore the title of viscount and held hereditary positions in the Lu bureaucracy. The Ji family held the position \"Minister over the Masses\", who was also the \"Prime Minister\"; the Meng family held the position \"Minister of Works\"; and the Shu family held the position \"Minister of War\". In the winter of 505 BCE, Yang Hu—a retainer of the Ji family—rose up in rebellion and seized power from the Ji family. However, by the summer of 501 BCE, the three hereditary families had succeeded in expelling Yang Hu from Lu. By then, Confucius had built up a considerable reputation through his teachings, while the families came to see the value of proper conduct and righteousness, so they could achieve loyalty to a legitimate government. Thus, that year (501 BCE), Confucius came to be appointed to the minor position of governor of a town. Eventually, he rose to the position of Minister of Crime. It was said in Xunzi that once assuming the post, Confucius ordered the execution of Shaozheng Mao, another Lu state official and scholar whose lectures attracted the three thousand disciples several times except Yan Hui. Shaozheng Mao was accused of 'five crimes', each worth execution, including 'concealed evilness, stubborn abnormality, eloquent duplicity, erudition in bizarre facts and generosity to evildoers'.",

Although the Meng and Shu families unsuccessfully besieged Hou, a loyalist official rose up with the people of Hou and forced Hou Fan to flee to the Qi state. The situation may have been in favor for Confucius as this likely made it possible for Confucius and his disciples to convince the aristocratic families to dismantle the fortifications of their cities. Eventually, after a year and a half, Confucius and his disciples succeeded in convincing the Shu family to raze the walls of Hou, the Ji family in razing the walls of Bi, and the Meng family in razing the walls of Cheng.

Confucius disapproved the use of a violent revolution by principle, even though the Ji family dominated the Lu state by force for generations and had exiled the previous duke. Creel (1949) states that, unlike the rebel Yang Hu before him, Gongshan may have sought to destroy the three hereditary families and restore the power of the duke. However, Dubs (1946) is of the view that Gongshan was encouraged by Viscount Ji Huan to invade the Lu capital in an attempt to avoid dismantling the Bi fortified walls.

His teachings rarely rely on reasoned argument, and ethical ideals and methods are conveyed indirectly, through allusion, innuendo, and even tautology.

] | Kong Qiu, generally known as Kongzi or Kong Fuzi and commonly Latinized to Confucius, was a Chinese philosopher of the Spring and Autumn period who is traditionally considered the paragon of Chinese sages. Confucius's teachings and philosophy underpin East Asian culture and society, and remain influential across China and East Asia to this day. His philosophical teachings, called Confucianism, emphasized personal and governmental morality, correctness of social relationships, justice, kindness, and sincerity, as well as an emphasis on a ruler's duty to their subjects. Confucius considered himself a transmitter for the values of earlier periods which he claimed had been abandoned in his time. The time immediately following Confucius's life saw a rich diversity of thought, and was a formative period in China's intellectual history. His ideas gained in prominence during the Warring States period, but experienced setback immediately following the Qin conquest. Under Emperor Wu of Han, Confucius's ideas received official sanction, with affiliated works becoming required reading for one of the career paths to officialdom. During the Tang and Song dynasties, Confucianism developed into a system known in the West as Neo-Confucianism, and later as New Confucianism. Confucianism became part of the Chinese social fabric and way of life. Confucius is traditionally credited with having authored or edited many of the Chinese classic texts, including all of the Five Classics, but modern scholars are cautious of attributing specific assertions to Confucius himself. At least some of the texts and philosophy he taught were already ancient. Aphorisms concerning his teachings were compiled in the Analects, but only many years after his death. Confucius's principles have commonality with Chinese tradition and belief. With filial piety, he championed strong family loyalty, ancestor veneration, and respect of elders by their children and of husbands by their wives, recommending family as a basis for ideal government. He espoused the Golden Rule, "Do not do unto others what you do not want done to yourself." | 2001-10-21T23:03:49Z | 2023-12-29T03:50:11Z | [

5,826 | Complex number | In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation i 2 = − 1 {\displaystyle i^{2}=-1} ; every complex number can be expressed in the form a + b i {\displaystyle a+bi} , where a and b are real numbers. Because no real number satisfies the above equation, i was called an imaginary number by René Descartes. For the complex number a + b i {\displaystyle a+bi} , a is called the real part, and b is called the imaginary part. The set of complex numbers is denoted by either of the symbols C {\displaystyle \mathbb {C} } or C. Despite the historical nomenclature "imaginary", complex numbers are regarded in the mathematical sciences as just as "real" as the real numbers and are fundamental in many aspects of the scientific description of the natural world.
Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or complex coefficients has a solution which is a complex number. For example, the equation ( x + 1 ) 2 = − 9 {\displaystyle (x+1)^{2}=-9} has no real solution, since the square of a real number cannot be negative, but has the two nonreal complex solutions − 1 + 3 i {\displaystyle -1+3i} and − 1 − 3 i {\displaystyle -1-3i} .
Addition, subtraction and multiplication of complex numbers can be naturally defined by using the rule i 2 = − 1 {\displaystyle i^{2}=-1} combined with the associative, commutative, and distributive laws. Every nonzero complex number has a multiplicative inverse. This makes the complex numbers a field that has the real numbers as a subfield. The complex numbers also form a real vector space of dimension two, with {1, i} as a standard basis.
This standard basis makes the complex numbers a Cartesian plane, called the complex plane. This allows a geometric interpretation of the complex numbers and their operations, and conversely expressing in terms of complex numbers some geometric properties and constructions. For example, the real numbers form the real line which is identified to the horizontal axis of the complex plane. The complex numbers of absolute value one form the unit circle. The addition of a complex number is a translation in the complex plane, and the multiplication by a complex number is a similarity centered at the origin. The complex conjugation is the reflection symmetry with respect to the real axis. The complex absolute value is a Euclidean norm.
In summary, the complex numbers form a rich structure that is simultaneously an algebraically closed field, a commutative algebra over the reals, and a Euclidean vector space of dimension two.
A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i = −1. For example, 2 + 3i is a complex number.
This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i + 1 = 0 is imposed. Based on this definition, complex numbers can be added and multiplied, using the addition and multiplication for polynomials. The relation i + 1 = 0 induces the equalities i = 1, i = i, i = −1, and i = −i, which hold for all integers k; these allow the reduction of any polynomial that results from the addition and multiplication of complex numbers to a linear polynomial in i, again of the form a + bi with real coefficients a, b.
The real number a is called the real part of the complex number a + bi; the real number b is called its imaginary part. To emphasize, the imaginary part does not include a factor i; that is, the imaginary part is b, not bi.
Formally, the complex numbers are defined as the quotient ring of the polynomial ring in the indeterminate i, by the ideal generated by the polynomial i + 1 (see below).
A real number a can be regarded as a complex number a + 0i, whose imaginary part is 0. A purely imaginary number bi is a complex number 0 + bi, whose real part is zero. As with polynomials, it is common to write a for a + 0i and bi for 0 + bi. Moreover, when the imaginary part is negative, that is, b = −|b| < 0, it is common to write a − |b|i instead of a + (−|b|)i; for example, for b = −4, 3 − 4i can be written instead of 3 + (−4)i.
Since the multiplication of the indeterminate i and a real is commutative in polynomials with real coefficients, the polynomial a + bi may be written as a + ib. This is often expedient for imaginary parts denoted by expressions, for example, when b is a radical.
The real part of a complex number z is denoted by Re(z), R e ( z ) {\displaystyle {\mathcal {Re}}(z)} , or R ( z ) {\displaystyle {\mathfrak {R}}(z)} ; the imaginary part of a complex number z is denoted by Im(z), I m ( z ) {\displaystyle {\mathcal {Im}}(z)} , or I ( z ) . {\displaystyle {\mathfrak {I}}(z).} For example,
The set of all complex numbers is denoted by C {\displaystyle \mathbb {C} } (blackboard bold) or C (upright bold).
In some disciplines, particularly in electromagnetism and electrical engineering, j is used instead of i as i is frequently used to represent electric current. In these cases, complex numbers are written as a + bj, or a + jb.
A complex number z can thus be identified with an ordered pair ( ℜ ( z ) , ℑ ( z ) ) {\displaystyle (\Re (z),\Im (z))} of real numbers, which in turn may be interpreted as coordinates of a point in a two-dimensional space. The most immediate space is the Euclidean plane with suitable coordinates, which is then called complex plane or Argand diagram, named after Jean-Robert Argand. Another prominent space on which the coordinates may be projected is the two-dimensional surface of a sphere, which is then called Riemann sphere.
The definition of the complex numbers involving two arbitrary real values immediately suggests the use of Cartesian coordinates in the complex plane. The horizontal (real) axis is generally used to display the real part, with increasing values to the right, and the imaginary part marks the vertical (imaginary) axis, with increasing values upwards.
A charted number may be viewed either as the coordinatized point or as a position vector from the origin to this point. The coordinate values of a complex number z can hence be expressed in its Cartesian, rectangular, or algebraic form.
Notably, the operations of addition and multiplication take on a very natural geometric character, when complex numbers are viewed as position vectors: addition corresponds to vector addition, while multiplication (see below) corresponds to multiplying their magnitudes and adding the angles they make with the real axis. Viewed in this way, the multiplication of a complex number by i corresponds to rotating the position vector counterclockwise by a quarter turn (90°) about the origin—a fact which can be expressed algebraically as
An alternative option for coordinates in the complex plane is the polar coordinate system that uses the distance of the point z from the origin (O), and the angle subtended between the positive real axis and the line segment Oz in a counterclockwise sense. This leads to the polar form
of a complex number, where r is the absolute value of z, and φ {\displaystyle \varphi } is the argument of z.
The absolute value (or modulus or magnitude) of a complex number z = x + yi is
If z is a real number (that is, if y = 0), then r = |x|. That is, the absolute value of a real number equals its absolute value as a complex number.
By Pythagoras' theorem, the absolute value of a complex number is the distance to the origin of the point representing the complex number in the complex plane.
The argument of z (in many applications referred to as the "phase" φ) is the angle of the radius Oz with the positive real axis, and is written as arg z. As with the modulus, the argument can be found from the rectangular form x + yi by applying the inverse tangent to the quotient of imaginary-by-real parts. By using a half-angle identity, a single branch of the arctan suffices to cover the range (−π, π] of the arg-function, and avoids a more subtle case-by-case analysis
Normally, as given above, the principal value in the interval (−π, π] is chosen. If the arg value is negative, values in the range (−π, π] or [0, 2π) can be obtained by adding 2π. The value of φ is expressed in radians in this article. It can increase by any integer multiple of 2π and still give the same angle, viewed as subtended by the rays of the positive real axis and from the origin through z. Hence, the arg function is sometimes considered as multivalued. The polar angle for the complex number 0 is indeterminate, but arbitrary choice of the polar angle 0 is common.
The value of φ equals the result of atan2:
Together, r and φ give another way of representing complex numbers, the polar form, as the combination of modulus and argument fully specify the position of a point on the plane. Recovering the original rectangular co-ordinates from the polar form is done by the formula called trigonometric form
Using Euler's formula this can be written as
Using the cis function, this is sometimes abbreviated to
In angle notation, often used in electronics to represent a phasor with amplitude r and phase φ, it is written as
When visualizing complex functions, both a complex input and output are needed. Because each complex number is represented in two dimensions, visually graphing a complex function would require the perception of a four dimensional space, which is possible only in projections. Because of this, other ways of visualizing complex functions have been designed.
In domain coloring the output dimensions are represented by color and brightness, respectively. Each point in the complex plane as domain is ornated, typically with color representing the argument of the complex number, and brightness representing the magnitude. Dark spots mark moduli near zero, brighter spots are farther away from the origin, the gradation may be discontinuous, but is assumed as monotonous. The colors often vary in steps of π/3 for 0 to 2π from red, yellow, green, cyan, blue, to magenta. These plots are called color wheel graphs. This provides a simple way to visualize the functions without losing information. The picture shows zeros for ±1, (2 + i) and poles at ± − 2 − 2 i . {\displaystyle \pm {\sqrt {-2-2i}}.}
The solution in radicals (without trigonometric functions) of a general cubic equation, when all three of its roots are real numbers, contains the square roots of negative numbers, a situation that cannot be rectified by factoring aided by the rational root test, if the cubic is irreducible; this is the so-called casus irreducibilis ("irreducible case"). This conundrum led Italian mathematician Gerolamo Cardano to conceive of complex numbers in around 1545 in his Ars Magna, though his understanding was rudimentary; moreover he later described complex numbers as "as subtle as they are useless". Cardano did use imaginary numbers, but described using them as "mental torture." This was prior to the use of the graphical complex plane. Cardano and other Italian mathematicians, notably Scipione del Ferro, in the 1500s created an algorithm for solving cubic equations which generally had one real solution and two solutions containing an imaginary number. Since they ignored the answers with the imaginary numbers, Cardano found them useless.
Work on the problem of general polynomials ultimately led to the fundamental theorem of algebra, which shows that with complex numbers, a solution exists to every polynomial equation of degree one or higher. Complex numbers thus form an algebraically closed field, where any polynomial equation has a root.
Many mathematicians contributed to the development of complex numbers. The rules for addition, subtraction, multiplication, and root extraction of complex numbers were developed by the Italian mathematician Rafael Bombelli. A more abstract formalism for the complex numbers was further developed by the Irish mathematician William Rowan Hamilton, who extended this abstraction to the theory of quaternions.
The earliest fleeting reference to square roots of negative numbers can perhaps be said to occur in the work of the Greek mathematician Hero of Alexandria in the 1st century AD, where in his Stereometrica he considered, apparently in error, the volume of an impossible frustum of a pyramid to arrive at the term 81 − 144 {\displaystyle {\sqrt {81-144}}} in his calculations, which today would simplify to − 63 = 3 i 7 {\displaystyle {\sqrt {-63}}=3i{\sqrt {7}}} . Negative quantities were not conceived of in Hellenistic mathematics and Hero merely replaced it by its positive 144 − 81 = 3 7 . {\displaystyle {\sqrt {144-81}}=3{\sqrt {7}}.}
The impetus to study complex numbers as a topic in itself first arose in the 16th century when algebraic solutions for the roots of cubic and quartic polynomials were discovered by Italian mathematicians (Niccolò Fontana Tartaglia and Gerolamo Cardano). It was soon realized (but proved much later) that these formulas, even if one were interested only in real solutions, sometimes required the manipulation of square roots of negative numbers. In fact, it was proved later that the use of complex numbers is unavoidable when all three roots are real and distinct. However, the general formula can still be used in this case, with some care to deal with the ambiguity resulting from the existence of three cubic roots for nonzero complex numbers. Rafael Bombelli was the first to address explicitly these seemingly paradoxical solutions of cubic equations and developed the rules for complex arithmetic, trying to resolve these issues.
The term "imaginary" for these quantities was coined by René Descartes in 1637, who was at pains to stress their unreal nature:
... sometimes only imaginary, that is one can imagine as many as I said in each equation, but sometimes there exists no quantity that matches that which we imagine. [... quelquefois seulement imaginaires c'est-à-dire que l'on peut toujours en imaginer autant que j'ai dit en chaque équation, mais qu'il n'y a quelquefois aucune quantité qui corresponde à celle qu'on imagine.]
A further source of confusion was that the equation − 1 2 = − 1 − 1 = − 1 {\displaystyle {\sqrt {-1}}^{2}={\sqrt {-1}}{\sqrt {-1}}=-1} seemed to be capriciously inconsistent with the algebraic identity a b = a b {\displaystyle {\sqrt {a}}{\sqrt {b}}={\sqrt {ab}}} , which is valid for non-negative real numbers a and b, and which was also used in complex number calculations with one of a, b positive and the other negative. The incorrect use of this identity in the case when both a and b are negative, and the related identity 1 a = 1 a {\textstyle {\frac {1}{\sqrt {a}}}={\sqrt {\frac {1}{a}}}} , even bedeviled Leonhard Euler. This difficulty eventually led to the convention of using the special symbol i in place of − 1 {\displaystyle {\sqrt {-1}}} to guard against this mistake. Even so, Euler considered it natural to introduce students to complex numbers much earlier than we do today. In his elementary algebra text book, Elements of Algebra, he introduces these numbers almost at once and then uses them in a natural way throughout.
In the 18th century complex numbers gained wider use, as it was noticed that formal manipulation of complex expressions could be used to simplify calculations involving trigonometric functions. For instance, in 1730 Abraham de Moivre noted that the identities relating trigonometric functions of an integer multiple of an angle to powers of trigonometric functions of that angle could be re-expressed by the following de Moivre's formula:
In 1748, Euler went further and obtained Euler's formula of complex analysis:
by formally manipulating complex power series and observed that this formula could be used to reduce any trigonometric identity to much simpler exponential identities.
The idea of a complex number as a point in the complex plane (above) was first described by Danish–Norwegian mathematician Caspar Wessel in 1799, although it had been anticipated as early as 1685 in Wallis's A Treatise of Algebra.
Wessel's memoir appeared in the Proceedings of the Copenhagen Academy but went largely unnoticed. In 1806 Jean-Robert Argand independently issued a pamphlet on complex numbers and provided a rigorous proof of the fundamental theorem of algebra. Carl Friedrich Gauss had earlier published an essentially topological proof of the theorem in 1797 but expressed his doubts at the time about "the true metaphysics of the square root of −1". It was not until 1831 that he overcame these doubts and published his treatise on complex numbers as points in the plane, largely establishing modern notation and terminology:
If one formerly contemplated this subject from a false point of view and therefore found a mysterious darkness, this is in large part attributable to clumsy terminology. Had one not called +1, −1, − 1 {\displaystyle {\sqrt {-1}}} positive, negative, or imaginary (or even impossible) units, but instead, say, direct, inverse, or lateral units, then there could scarcely have been talk of such darkness.
In the beginning of the 19th century, other mathematicians discovered independently the geometrical representation of the complex numbers: Buée, Mourey, Warren, Français and his brother, Bellavitis.
The English mathematician G.H. Hardy remarked that Gauss was the first mathematician to use complex numbers in "a really confident and scientific way" although mathematicians such as Norwegian Niels Henrik Abel and Carl Gustav Jacob Jacobi were necessarily using them routinely before Gauss published his 1831 treatise.
Augustin-Louis Cauchy and Bernhard Riemann together brought the fundamental ideas of complex analysis to a high state of completion, commencing around 1825 in Cauchy's case.
The common terms used in the theory are chiefly due to the founders. Argand called cos φ + i sin φ the direction factor, and r = a 2 + b 2 {\displaystyle r={\sqrt {a^{2}+b^{2}}}} the modulus; Cauchy (1821) called cos φ + i sin φ the reduced form (l'expression réduite) and apparently introduced the term argument; Gauss used i for − 1 {\displaystyle {\sqrt {-1}}} , introduced the term complex number for a + bi, and called a + b the norm. The expression direction coefficient, often used for cos φ + i sin φ, is due to Hankel (1867), and absolute value, for modulus, is due to Weierstrass.
Later classical writers on the general theory include Richard Dedekind, Otto Hölder, Felix Klein, Henri Poincaré, Hermann Schwarz, Karl Weierstrass and many others. Important work (including a systematization) in complex multivariate calculus has been started at beginning of the 20th century. Important results have been achieved by Wilhelm Wirtinger in 1927.
Complex numbers have a similar definition of equality to real numbers; two complex numbers a1 + b1i and a2 + b2i are equal if and only if both their real and imaginary parts are equal, that is, if a1 = a2 and b1 = b2. Nonzero complex numbers written in polar form are equal if and only if they have the same magnitude and their arguments differ by an integer multiple of 2π.
Unlike the real numbers, there is no natural ordering of the complex numbers. In particular, there is no linear ordering on the complex numbers that is compatible with addition and multiplication. Hence, the complex numbers do not have the structure of an ordered field. One explanation for this is that every non-trivial sum of squares in an ordered field is nonzero, and i + 1 = 0 is a non-trivial sum of squares. Thus, complex numbers are naturally thought of as existing on a two-dimensional plane.
The complex conjugate of the complex number z = x + yi is given by x − yi. It is denoted by either z or z*. This unary operation on complex numbers cannot be expressed by applying only their basic operations addition, subtraction, multiplication and division.
Geometrically, z is the "reflection" of z about the real axis. Conjugating twice gives the original complex number
which makes this operation an involution. The reflection leaves both the real part and the magnitude of z unchanged, that is
and | z ¯ | = | z | . {\displaystyle \quad |{\overline {z}}|=|z|.}
The imaginary part and the argument of a complex number z change their sign under conjugation
For details on argument and magnitude, see the section on Polar form.
The product of a complex number z = x + yi and its conjugate is known as the absolute square. It is always a non-negative real number and equals the square of the magnitude of each:
This property can be used to convert a fraction with a complex denominator to an equivalent fraction with a real denominator by expanding both numerator and denominator of the fraction by the conjugate of the given denominator. This process is sometimes called "rationalization" of the denominator (although the denominator in the final expression might be an irrational real number), because it resembles the method to remove roots from simple expressions in a denominator.
The real and imaginary parts of a complex number z can be extracted using the conjugation:
Moreover, a complex number is real if and only if it equals its own conjugate.
Conjugation distributes over the basic complex arithmetic operations:
Conjugation is also employed in inversive geometry, a branch of geometry studying reflections more general than ones about a line. In the network analysis of electrical circuits, the complex conjugate is used in finding the equivalent impedance when the maximum power transfer theorem is looked for.
Two complex numbers a = x + y i {\displaystyle a=x+yi} and b = u + v i {\displaystyle b=u+vi} are most easily added by separately adding their real and imaginary parts. That is to say:
Similarly, subtraction can be performed as
Multiplication of a complex number a = x + y i {\displaystyle a=x+yi} and a real number r can be done similarly by multiplying separately r and the real and imaginary parts of a:
In particular, subtraction can be done by negating the subtrahend (that is multiplying it with −1) and adding the result to the minuend:
Using the visualization of complex numbers in the complex plane, addition has the following geometric interpretation: the sum of two complex numbers a and b, interpreted as points in the complex plane, is the point obtained by building a parallelogram from the three vertices O, and the points of the arrows labeled a and b (provided that they are not on a line). Equivalently, calling these points A, B, respectively and the fourth point of the parallelogram X the triangles OAB and XBA are congruent.
The rules of the distributive property, the commutative properties (of addition and multiplication), and the defining property i = −1 apply to complex numbers. It follows that
In particular,
Using the conjugate, the reciprocal of a nonzero complex number z = x + y i {\displaystyle z=x+yi} can be broken into real and imaginary components
This can be used to express a division of an arbitrary complex number w = u + v i {\displaystyle w=u+vi} by a non-zero complex number z = x + y i {\displaystyle z=x+yi} as
Formulas for multiplication, division and exponentiation are simpler in polar form than the corresponding formulas in Cartesian coordinates. Given two complex numbers z1 = r1(cos φ1 + i sin φ1) and z2 = r2(cos φ2 + i sin φ2), because of the trigonometric identities
we may derive
In other words, the absolute values are multiplied and the arguments are added to yield the polar form of the product. For example, multiplying by i corresponds to a quarter-turn counter-clockwise, which gives back i = −1. The picture at the right illustrates the multiplication of
Since the real and imaginary part of 5 + 5i are equal, the argument of that number is 45 degrees, or π/4 (in radian). On the other hand, it is also the sum of the angles at the origin of the red and blue triangles are arctan(1/3) and arctan(1/2), respectively. Thus, the formula
holds. As the arctan function can be approximated highly efficiently, formulas like this – known as Machin-like formulas – are used for high-precision approximations of π.
Similarly, division is given by
The square roots of a + bi (with b ≠ 0) are ± ( γ + δ i ) {\displaystyle \pm (\gamma +\delta i)} , where
and
where sgn is the signum function. This can be seen by squaring ± ( γ + δ i ) {\displaystyle \pm (\gamma +\delta i)} to obtain a + bi. Here a 2 + b 2 {\displaystyle {\sqrt {a^{2}+b^{2}}}} is called the modulus of a + bi, and the square root sign indicates the square root with non-negative real part, called the principal square root; also a 2 + b 2 = z z ¯ , {\displaystyle {\sqrt {a^{2}+b^{2}}}={\sqrt {z{\overline {z}}}},} where z = a + bi.
The exponential function exp : C → C ; z ↦ exp z {\displaystyle \exp \colon \mathbb {C} \to \mathbb {C} ;z\mapsto \exp z} can be defined for every complex number z by the power series
which has an infinite radius of convergence.
The value at 1 of the exponential function is Euler's number
If z is real, one has exp z = e z . {\displaystyle \exp z=e^{z}.} Analytic continuation allows extending this equality for every complex value of z, and thus to define the complex exponentiation with base e as
The exponential function satisfies the functional equation e z + t = e z e t . {\displaystyle e^{z+t}=e^{z}e^{t}.} This can be proved either by comparing the power series expansion of both members or by applying analytic continuation from the restriction of the equation to real arguments.
Euler's formula states that, for any real number y,
The functional equation implies thus that, if x and y are real, one has
which is the decomposition of the exponential function into its real and imaginary parts.
In the real case, the natural logarithm can be defined as the inverse ln : R + → R ; x ↦ ln x {\displaystyle \ln \colon \mathbb {R} ^{+}\to \mathbb {R} ;x\mapsto \ln x} of the exponential function. For extending this to the complex domain, one can start from Euler's formula. It implies that, if a complex number z ∈ C × {\displaystyle z\in \mathbb {C} ^{\times }} is written in polar form
with r , φ ∈ R , {\displaystyle r,\varphi \in \mathbb {R} ,} then with
as complex logarithm one has a proper inverse:
However, because cosine and sine are periodic functions, the addition of an integer multiple of 2π to φ does not change z. For example, e = e = −1 , so both iπ and 3iπ are possible values for the natural logarithm of −1.
Therefore, if the complex logarithm is not to be defined as a multivalued function
one has to use a branch cut and to restrict the codomain, resulting in the bijective function
If z ∈ C ∖ ( − R ≥ 0 ) {\displaystyle z\in \mathbb {C} \setminus \left(-\mathbb {R} _{\geq 0}\right)} is not a non-positive real number (a positive or a non-real number), the resulting principal value of the complex logarithm is obtained with −π < φ < π. It is an analytic function outside the negative real numbers, but it cannot be prolongated to a function that is continuous at any negative real number z ∈ − R + {\displaystyle z\in -\mathbb {R} ^{+}} , where the principal value is ln z = ln(−z) + iπ.
If x > 0 is real and z complex, the exponentiation is defined as
where ln denotes the natural logarithm.
It seems natural to extend this formula to complex values of x, but there are some difficulties resulting from the fact that the complex logarithm is not really a function, but a multivalued function.
It follows that if z is as above, and if t is another complex number, then the exponentiation is the multivalued function
If, in the preceding formula, t is an integer, then the sine and the cosine are independent of k. Thus, if the exponent n is an integer, then z is well defined, and the exponentiation formula simplifies to de Moivre's formula:
The n nth roots of a complex number z are given by
for 0 ≤ k ≤ n − 1. (Here r n {\displaystyle {\sqrt[{n}]{r}}} is the usual (positive) nth root of the positive real number r.) Because sine and cosine are periodic, other integer values of k do not give other values.
While the nth root of a positive real number r is chosen to be the positive real number c satisfying c = r, there is no natural way of distinguishing one particular complex nth root of a complex number. Therefore, the nth root is a n-valued function of z. This implies that, contrary to the case of positive real numbers, one has
since the left-hand side consists of n values, and the right-hand side is a single value.
The set C {\displaystyle \mathbb {C} } of complex numbers is a field. Briefly, this means that the following facts hold: first, any two complex numbers can be added and multiplied to yield another complex number. Second, for any complex number z, its additive inverse –z is also a complex number; and third, every nonzero complex number has a reciprocal complex number. Moreover, these operations satisfy a number of laws, for example the law of commutativity of addition and multiplication for any two complex numbers z1 and z2:
These two laws and the other requirements on a field can be proven by the formulas given above, using the fact that the real numbers themselves form a field.
Unlike the reals, C {\displaystyle \mathbb {C} } is not an ordered field, that is to say, it is not possible to define a relation z1 < z2 that is compatible with the addition and multiplication. In fact, in any ordered field, the square of any element is necessarily positive, so i = −1 precludes the existence of an ordering on C . {\displaystyle \mathbb {C} .}
When the underlying field for a mathematical topic or construct is the field of complex numbers, the topic's name is usually modified to reflect that fact. For example: complex analysis, complex matrix, complex polynomial, and complex Lie algebra.
Given any complex numbers (called coefficients) a0, ..., an, the equation
has at least one complex solution z, provided that at least one of the higher coefficients a1, ..., an is nonzero. This is the statement of the fundamental theorem of algebra, of Carl Friedrich Gauss and Jean le Rond d'Alembert. Because of this fact, C {\displaystyle \mathbb {C} } is called an algebraically closed field. This property does not hold for the field of rational numbers Q {\displaystyle \mathbb {Q} } (the polynomial x − 2 does not have a rational root, since √2 is not a rational number) nor the real numbers R {\displaystyle \mathbb {R} } (the polynomial x + a does not have a real root for a > 0, since the square of x is positive for any real number x).
There are various proofs of this theorem, by either analytic methods such as Liouville's theorem, or topological ones such as the winding number, or a proof combining Galois theory and the fact that any real polynomial of odd degree has at least one real root.
Because of this fact, theorems that hold for any algebraically closed field apply to C . {\displaystyle \mathbb {C} .} For example, any non-empty complex square matrix has at least one (complex) eigenvalue.
The field C {\displaystyle \mathbb {C} } has the following three properties:
It can be shown that any field having these properties is isomorphic (as a field) to C . {\displaystyle \mathbb {C} .} For example, the algebraic closure of the field Q p {\displaystyle \mathbb {Q} _{p}} of the p-adic number also satisfies these three properties, so these two fields are isomorphic (as fields, but not as topological fields). Also, C {\displaystyle \mathbb {C} } is isomorphic to the field of complex Puiseux series. However, specifying an isomorphism requires the axiom of choice. Another consequence of this algebraic characterization is that C {\displaystyle \mathbb {C} } contains many proper subfields that are isomorphic to C {\displaystyle \mathbb {C} } .
The preceding characterization of C {\displaystyle \mathbb {C} } describes only the algebraic aspects of C . {\displaystyle \mathbb {C} .} That is to say, the properties of nearness and continuity, which matter in areas such as analysis and topology, are not dealt with. The following description of C {\displaystyle \mathbb {C} } as a topological field (that is, a field that is equipped with a topology, which allows the notion of convergence) does take into account the topological properties. C {\displaystyle \mathbb {C} } contains a subset P (namely the set of positive real numbers) of nonzero elements satisfying the following three conditions:
Moreover, C {\displaystyle \mathbb {C} } has a nontrivial involutive automorphism x ↦ x* (namely the complex conjugation), such that x x* is in P for any nonzero x in C . {\displaystyle \mathbb {C} .}
Any field F with these properties can be endowed with a topology by taking the sets B(x, p) = { y | p − (y − x)(y − x)* ∈ P } as a base, where x ranges over the field and p ranges over P. With this topology F is isomorphic as a topological field to C . {\displaystyle \mathbb {C} .}
The only connected locally compact topological fields are R {\displaystyle \mathbb {R} } and C . {\displaystyle \mathbb {C} .} This gives another characterization of C {\displaystyle \mathbb {C} } as a topological field, since C {\displaystyle \mathbb {C} } can be distinguished from R {\displaystyle \mathbb {R} } because the nonzero complex numbers are connected, while the nonzero real numbers are not.
William Rowan Hamilton introduced the approach to define the set C {\displaystyle \mathbb {C} } of complex numbers as the set R 2 {\displaystyle \mathbb {R} ^{2}} of ordered pairs (a, b) of real numbers, in which the following rules for addition and multiplication are imposed:
It is then just a matter of notation to express (a, b) as a + bi.
Though this low-level construction does accurately describe the structure of the complex numbers, the following equivalent definition reveals the algebraic nature of C {\displaystyle \mathbb {C} } more immediately. This characterization relies on the notion of fields and polynomials. A field is a set endowed with addition, subtraction, multiplication and division operations that behave as is familiar from, say, rational numbers. For example, the distributive law
must hold for any three elements x, y and z of a field. The set R {\displaystyle \mathbb {R} } of real numbers does form a field. A polynomial p(X) with real coefficients is an expression of the form
where the a0, ..., an are real numbers. The usual addition and multiplication of polynomials endows the set R [ X ] {\displaystyle \mathbb {R} [X]} of all such polynomials with a ring structure. This ring is called the polynomial ring over the real numbers.
The set of complex numbers is defined as the quotient ring R [ X ] / ( X 2 + 1 ) . {\displaystyle \mathbb {R} [X]/(X^{2}+1).} This extension field contains two square roots of −1, namely (the cosets of) X and −X, respectively. (The cosets of) 1 and X form a basis of R [ X ] / ( X 2 + 1 ) {\displaystyle \mathbb {R} [X]/(X^{2}+1)} as a real vector space, which means that each element of the extension field can be uniquely written as a linear combination in these two elements. Equivalently, elements of the extension field can be written as ordered pairs (a, b) of real numbers. The quotient ring is a field, because X + 1 is irreducible over R , {\displaystyle \mathbb {R} ,} so the ideal it generates is maximal.
The formulas for addition and multiplication in the ring R [ X ] , {\displaystyle \mathbb {R} [X],} modulo the relation X = −1, correspond to the formulas for addition and multiplication of complex numbers defined as ordered pairs. So the two definitions of the field C {\displaystyle \mathbb {C} } are isomorphic (as fields).
Accepting that C {\displaystyle \mathbb {C} } is algebraically closed, since it is an algebraic extension of R {\displaystyle \mathbb {R} } in this approach, C {\displaystyle \mathbb {C} } is therefore the algebraic closure of R . {\displaystyle \mathbb {R} .}
Complex numbers a + bi can also be represented by 2 × 2 matrices that have the form:
Here the entries a and b are real numbers. As the sum and product of two such matrices is again of this form, these matrices form a subring of the ring 2 × 2 matrices.
A simple computation shows that the map:
is a ring isomorphism from the field of complex numbers to the ring of these matrices. This isomorphism associates the square of the absolute value of a complex number with the determinant of the corresponding matrix, and the conjugate of a complex number with the transpose of the matrix.
The geometric description of the multiplication of complex numbers can also be expressed in terms of rotation matrices by using this correspondence between complex numbers and such matrices. The action of the matrix on a vector (x, y) corresponds to the multiplication of x + iy by a + ib. In particular, if the determinant is 1, there is a real number t such that the matrix has the form:
In this case, the action of the matrix on vectors and the multiplication by the complex number cos t + i sin t {\displaystyle \cos t+i\sin t} are both the rotation of the angle t.
The study of functions of a complex variable is known as complex analysis and has enormous practical use in applied mathematics as well as in other branches of mathematics. Often, the most natural proofs for statements in real analysis or even number theory employ techniques from complex analysis (see prime number theorem for an example). Unlike real functions, which are commonly represented as two-dimensional graphs, complex functions have four-dimensional graphs and may usefully be illustrated by color-coding a three-dimensional graph to suggest four dimensions, or by animating the complex function's dynamic transformation of the complex plane.
The notions of convergent series and continuous functions in (real) analysis have natural analogs in complex analysis. A sequence of complex numbers is said to converge if and only if its real and imaginary parts do. This is equivalent to the (ε, δ)-definition of limits, where the absolute value of real numbers is replaced by the one of complex numbers. From a more abstract point of view, C {\displaystyle \mathbb {C} } , endowed with the metric
is a complete metric space, which notably includes the triangle inequality
for any two complex numbers z1 and z2.
Like in real analysis, this notion of convergence is used to construct a number of elementary functions: the exponential function exp z, also written e, is defined as the infinite series
The series defining the real trigonometric functions sine and cosine, as well as the hyperbolic functions sinh and cosh, also carry over to complex arguments without change. For the other trigonometric and hyperbolic functions, such as tangent, things are slightly more complicated, as the defining series do not converge for all complex values. Therefore, one must define them either in terms of sine, cosine and exponential, or, equivalently, by using the method of analytic continuation.
Euler's formula states:
for any real number φ, in particular
, which is Euler's identity.
Unlike in the situation of real numbers, there is an infinitude of complex solutions z of the equation
for any complex number w ≠ 0. It can be shown that any such solution z – called complex logarithm of w – satisfies
where arg is the argument defined above, and ln the (real) natural logarithm. As arg is a multivalued function, unique only up to a multiple of 2π, log is also multivalued. The principal value of log is often taken by restricting the imaginary part to the interval (−π, π].
Complex exponentiation z is defined as
and is multi-valued, except when ω is an integer. For ω = 1 / n, for some natural number n, this recovers the non-uniqueness of nth roots mentioned above.
Complex numbers, unlike real numbers, do not in general satisfy the unmodified power and logarithm identities, particularly when naïvely treated as single-valued functions; see failure of power and logarithm identities. For example, they do not satisfy
Both sides of the equation are multivalued by the definition of complex exponentiation given here, and the values on the left are a subset of those on the right.
A function f: C {\displaystyle \mathbb {C} } → C {\displaystyle \mathbb {C} } is said to be holomorphic at a point if it is complex differentiable in an open neighborhood of that point. A necessary (but not sufficient) condition for f to be holomorphic is that it satisfies the Cauchy–Riemann equations. For example, any R {\displaystyle \mathbb {R} } -linear map C {\displaystyle \mathbb {C} } → C {\displaystyle \mathbb {C} } can be written in the form
with complex coefficients a and b. This map is holomorphic if and only if b = 0. The function z ¯ {\displaystyle {\overline {z}}} is real-differentiable, but does not satisfy the Cauchy–Riemann equations.
Complex analysis shows some features not apparent in real analysis. For example, any two holomorphic functions f and g that agree on an arbitrarily small open subset of C {\displaystyle \mathbb {C} } necessarily agree everywhere. Meromorphic functions, functions that can locally be written as f(z)/(z − z0) with a holomorphic function f, still share some of the features of holomorphic functions. Other functions have essential singularities, such as sin(1/z) at z = 0.
Complex numbers have applications in many scientific areas, including signal processing, control theory, electromagnetism, fluid dynamics, quantum mechanics, cartography, and vibration analysis. Some of these applications are described below.
Three non-collinear points u , v , w {\displaystyle u,v,w} in the plane determine the shape of the triangle { u , v , w } {\displaystyle \{u,v,w\}} . Locating the points in the complex plane, this shape of a triangle may be expressed by complex arithmetic as
The shape S {\displaystyle S} of a triangle will remain the same, when the complex plane is transformed by translation or dilation (by an affine transformation), corresponding to the intuitive notion of shape, and describing similarity. Thus each triangle { u , v , w } {\displaystyle \{u,v,w\}} is in a similarity class of triangles with the same shape.
The Mandelbrot set is a popular example of a fractal formed on the complex plane. It is defined by plotting every location c {\displaystyle c} where iterating the sequence f c ( z ) = z 2 + c {\displaystyle f_{c}(z)=z^{2}+c} does not diverge when iterated infinitely. Similarly, Julia sets have the same rules, except where c {\displaystyle c} remains constant.
Every triangle has a unique Steiner inellipse – an ellipse inside the triangle and tangent to the midpoints of the three sides of the triangle. The foci of a triangle's Steiner inellipse can be found as follows, according to Marden's theorem: Denote the triangle's vertices in the complex plane as a = xA + yAi, b = xB + yBi, and c = xC + yCi. Write the cubic equation ( x − a ) ( x − b ) ( x − c ) = 0 {\displaystyle (x-a)(x-b)(x-c)=0} , take its derivative, and equate the (quadratic) derivative to zero. Marden's theorem says that the solutions of this equation are the complex numbers denoting the locations of the two foci of the Steiner inellipse.
As mentioned above, any nonconstant polynomial equation (in complex coefficients) has a solution in C {\displaystyle \mathbb {C} } . A fortiori, the same is true if the equation has rational coefficients. The roots of such equations are called algebraic numbers – they are a principal object of study in algebraic number theory. Compared to Q ¯ {\displaystyle {\overline {\mathbb {Q} }}} , the algebraic closure of Q {\displaystyle \mathbb {Q} } , which also contains all algebraic numbers, C {\displaystyle \mathbb {C} } has the advantage of being easily understandable in geometric terms. In this way, algebraic methods can be used to study geometric questions and vice versa. With algebraic methods, more specifically applying the machinery of field theory to the number field containing roots of unity, it can be shown that it is not possible to construct a regular nonagon using only compass and straightedge – a purely geometric problem.
Another example is the Gaussian integers; that is, numbers of the form x + iy, where x and y are integers, which can be used to classify sums of squares.
Analytic number theory studies numbers, often integers or rationals, by taking advantage of the fact that they can be regarded as complex numbers, in which analytic methods can be used. This is done by encoding number-theoretic information in complex-valued functions. For example, the Riemann zeta function ζ(s) is related to the distribution of prime numbers.
In applied fields, complex numbers are often used to compute certain real-valued improper integrals, by means of complex-valued functions. Several methods exist to do this; see methods of contour integration.
In differential equations, it is common to first find all complex roots r of the characteristic equation of a linear differential equation or equation system and then attempt to solve the system in terms of base functions of the form f(t) = e. Likewise, in difference equations, the complex roots r of the characteristic equation of the difference equation system are used, to attempt to solve the system in terms of base functions of the form f(t) = r.
Eigendecomposition is a useful tool for computing matrix powers and matrix exponentials. However, it often requires the use of complex numbers, even if the matrix is real (for example, a rotation matrix).
Complex numbers often generalize concepts originally conceived in the real numbers. For example, the conjugate transpose generalizes the transpose, hermitian matrices generalize symmetric matrices, and unitary matrices generalize orthogonal matrices.
In control theory, systems are often transformed from the time domain to the complex frequency domain using the Laplace transform. The system's zeros and poles are then analyzed in the complex plane. The root locus, Nyquist plot, and Nichols plot techniques all make use of the complex plane.
In the root locus method, it is important whether zeros and poles are in the left or right half planes, that is, have real part greater than or less than zero. If a linear, time-invariant (LTI) system has poles that are
If a system has zeros in the right half plane, it is a nonminimum phase system.
Complex numbers are used in signal analysis and other fields for a convenient description for periodically varying signals. For given real functions representing actual physical quantities, often in terms of sines and cosines, corresponding complex functions are considered of which the real parts are the original quantities. For a sine wave of a given frequency, the absolute value |z| of the corresponding z is the amplitude and the argument arg z is the phase.
If Fourier analysis is employed to write a given real-valued signal as a sum of periodic functions, these periodic functions are often written as complex-valued functions of the form
and
where ω represents the angular frequency and the complex number A encodes the phase and amplitude as explained above.
This use is also extended into digital signal processing and digital image processing, which use digital versions of Fourier analysis (and wavelet analysis) to transmit, compress, restore, and otherwise process digital audio signals, still images, and video signals.
Another example, relevant to the two side bands of amplitude modulation of AM radio, is:
In electrical engineering, the Fourier transform is used to analyze varying voltages and currents. The treatment of resistors, capacitors, and inductors can then be unified by introducing imaginary, frequency-dependent resistances for the latter two and combining all three in a single complex number called the impedance. This approach is called phasor calculus.
In electrical engineering, the imaginary unit is denoted by j, to avoid confusion with I, which is generally in use to denote electric current, or, more particularly, i, which is generally in use to denote instantaneous electric current.
Since the voltage in an AC circuit is oscillating, it can be represented as
To obtain the measurable quantity, the real part is taken:
The complex-valued signal V(t) is called the analytic representation of the real-valued, measurable signal v(t).
In fluid dynamics, complex functions are used to describe potential flow in two dimensions.
The complex number field is intrinsic to the mathematical formulations of quantum mechanics, where complex Hilbert spaces provide the context for one such formulation that is convenient and perhaps most standard. The original foundation formulas of quantum mechanics – the Schrödinger equation and Heisenberg's matrix mechanics – make use of complex numbers.
In special and general relativity, some formulas for the metric on spacetime become simpler if one takes the time component of the spacetime continuum to be imaginary. (This approach is no longer standard in classical relativity, but is used in an essential way in quantum field theory.) Complex numbers are essential to spinors, which are a generalization of the tensors used in relativity.
The process of extending the field R {\displaystyle \mathbb {R} } of reals to C {\displaystyle \mathbb {C} } is known as the Cayley–Dickson construction. It can be carried further to higher dimensions, yielding the quaternions H {\displaystyle \mathbb {H} } and octonions O {\displaystyle \mathbb {O} } which (as a real vector space) are of dimension 4 and 8, respectively. In this context the complex numbers have been called the binarions.
Just as by applying the construction to reals the property of ordering is lost, properties familiar from real and complex numbers vanish with each extension. The quaternions lose commutativity, that is, x·y ≠ y·x for some quaternions x, y, and the multiplication of octonions, additionally to not being commutative, fails to be associative: (x·y)·z ≠ x·(y·z) for some octonions x, y, z.
Reals, complex numbers, quaternions and octonions are all normed division algebras over R {\displaystyle \mathbb {R} } . By Hurwitz's theorem they are the only ones; the sedenions, the next step in the Cayley–Dickson construction, fail to have this structure.
The Cayley–Dickson construction is closely related to the regular representation of C , {\displaystyle \mathbb {C} ,} thought of as an R {\displaystyle \mathbb {R} } -algebra (an R {\displaystyle \mathbb {R} } -vector space with a multiplication), with respect to the basis (1, i). This means the following: the R {\displaystyle \mathbb {R} } -linear map
for some fixed complex number w can be represented by a 2 × 2 matrix (once a basis has been chosen). With respect to the basis (1, i), this matrix is
that is, the one mentioned in the section on matrix representation of complex numbers above. While this is a linear representation of C {\displaystyle \mathbb {C} } in the 2 × 2 real matrices, it is not the only one. Any matrix
has the property that its square is the negative of the identity matrix: J = −I. Then
is also isomorphic to the field C , {\displaystyle \mathbb {C} ,} and gives an alternative complex structure on R 2 . {\displaystyle \mathbb {R} ^{2}.} This is generalized by the notion of a linear complex structure.
Hypercomplex numbers also generalize R , {\displaystyle \mathbb {R} ,} C , {\displaystyle \mathbb {C} ,} H , {\displaystyle \mathbb {H} ,} and O . {\displaystyle \mathbb {O} .} For example, this notion contains the split-complex numbers, which are elements of the ring R [ x ] / ( x 2 − 1 ) {\displaystyle \mathbb {R} [x]/(x^{2}-1)} (as opposed to R [ x ] / ( x 2 + 1 ) {\displaystyle \mathbb {R} [x]/(x^{2}+1)} for complex numbers). In this ring, the equation a = 1 has four solutions.
The field R {\displaystyle \mathbb {R} } is the completion of Q , {\displaystyle \mathbb {Q} ,} the field of rational numbers, with respect to the usual absolute value metric. Other choices of metrics on Q {\displaystyle \mathbb {Q} } lead to the fields Q p {\displaystyle \mathbb {Q} _{p}} of p-adic numbers (for any prime number p), which are thereby analogous to R {\displaystyle \mathbb {R} } . There are no other nontrivial ways of completing Q {\displaystyle \mathbb {Q} } than R {\displaystyle \mathbb {R} } and Q p , {\displaystyle \mathbb {Q} _{p},} by Ostrowski's theorem. The algebraic closures Q p ¯ {\displaystyle {\overline {\mathbb {Q} _{p}}}} of Q p {\displaystyle \mathbb {Q} _{p}} still carry a norm, but (unlike C {\displaystyle \mathbb {C} } ) are not complete with respect to it. The completion C p {\displaystyle \mathbb {C} _{p}} of Q p ¯ {\displaystyle {\overline {\mathbb {Q} _{p}}}} turns out to be algebraically closed. By analogy, the field is called p-adic complex numbers.
The fields R , {\displaystyle \mathbb {R} ,} Q p , {\displaystyle \mathbb {Q} _{p},} and their finite field extensions, including C , {\displaystyle \mathbb {C} ,} are called local fields. | [

This conundrum led Italian mathematician Gerolamo Cardano to conceive of complex numbers in around 1545 in his Ars Magna, though his understanding was rudimentary; moreover he later described complex numbers as \"as subtle as they are useless\". Cardano did use imaginary numbers, but described using them as \"mental torture.\" This was prior to the use of the graphical complex plane. Cardano and other Italian mathematicians, notably Scipione del Ferro, in the 1500s created an algorithm for solving cubic equations which generally had one real solution and two solutions containing an imaginary number.

] | In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation i 2 = − 1 ; every complex number can be expressed in the form a + b i , where a and b are real numbers. Because no real number satisfies the above equation, i was called an imaginary number by René Descartes. For the complex number a + b i , a is called the real part, and b is called the imaginary part. The set of complex numbers is denoted by either of the symbols C or C. Despite the historical nomenclature "imaginary", complex numbers are regarded in the mathematical sciences as just as "real" as the real numbers and are fundamental in many aspects of the scientific description of the natural world. Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or complex coefficients has a solution which is a complex number. For example, the equation 2 = − 9 has no real solution, since the square of a real number cannot be negative, but has the two nonreal complex solutions − 1 + 3 i and − 1 − 3 i . Addition, subtraction and multiplication of complex numbers can be naturally defined by using the rule i 2 = − 1 combined with the associative, commutative, and distributive laws. Every nonzero complex number has a multiplicative inverse. This makes the complex numbers a field that has the real numbers as a subfield. The complex numbers also form a real vector space of dimension two, with {1, i} as a standard basis. This standard basis makes the complex numbers a Cartesian plane, called the complex plane. This allows a geometric interpretation of the complex numbers and their operations, and conversely expressing in terms of complex numbers some geometric properties and constructions. For example, the real numbers form the real line which is identified to the horizontal axis of the complex plane. The complex numbers of absolute value one form the unit circle. The addition of a complex number is a translation in the complex plane, and the multiplication by a complex number is a similarity centered at the origin. The complex conjugation is the reflection symmetry with respect to the real axis. The complex absolute value is a Euclidean norm. In summary, the complex numbers form a rich structure that is simultaneously an algebraically closed field, a commutative algebra over the reals, and a Euclidean vector space of dimension two. | 2001-11-18T22:01:51Z | 2023-12-29T21:49:45Z | [

5,828 | Cryptozoology | Cryptozoology is a pseudoscience and subculture that searches for and studies unknown, legendary, or extinct animals whose present existence is disputed or unsubstantiated, particularly those popular in folklore, such as Bigfoot, the Loch Ness Monster, Yeti, the chupacabra, the Jersey Devil, or the Mokele-mbembe. Cryptozoologists refer to these entities as cryptids, a term coined by the subculture. Because it does not follow the scientific method, cryptozoology is considered a pseudoscience by mainstream science: it is neither a branch of zoology nor of folklore studies. It was originally founded in the 1950s by zoologists Bernard Heuvelmans and Ivan T. Sanderson.
Scholars have noted that the subculture rejected mainstream approaches from an early date, and that adherents often express hostility to mainstream science. Scholars have studied cryptozoologists and their influence (including cryptozoology's association with Young Earth creationism), noted parallels in cryptozoology and other pseudosciences such as ghost hunting and ufology, and highlighted uncritical media propagation of cryptozoologist claims.
As a field, cryptozoology originates from the works of Bernard Heuvelmans, a Belgian zoologist, and Ivan T. Sanderson, a Scottish zoologist. Notably, Heuvelmans published On the Track of Unknown Animals (French Sur la Piste des Bêtes Ignorées) in 1955, a landmark work among cryptozoologists that was followed by numerous other like works. Similarly, Sanderson published a series of books that contributed to the developing hallmarks of cryptozoology, including Abominable Snowmen: Legend Come to Life (1961). Heuvelmans himself traced cryptozoology to the work of Anthonie Cornelis Oudemans, who theorized that a large unidentified species of seal was responsible for sea serpent reports.
Cryptozoology is 'the study of hidden animals' (from Ancient Greek: κρυπτός, kryptós "hidden, secret"; Ancient Greek ζῷον, zōion "animal", and λόγος, logos, i.e. "knowledge, study"). The term dates from 1959 or before— Heuvelmans attributes the coinage of the term cryptozoology to Sanderson. Following cryptozoology, the term cryptid was coined in 1983 by cryptozoologist J. E. Wall in the summer issue of the International Society of Cryptozoology newsletter. According to Wall "[It has been] suggested that new terms be coined to replace sensational and often misleading terms like 'monster'. My suggestion is 'cryptid', meaning a living thing having the quality of being hidden or unknown ... describing those creatures which are (or may be) subjects of cryptozoological investigation."
The Oxford English Dictionary defines the noun cryptid as "an animal whose existence or survival to the present day is disputed or unsubstantiated; any animal of interest to a cryptozoologist". While used by most cryptozoologists, the term cryptid is not used by academic zoologists. In a textbook aimed at undergraduates, academics Caleb W. Lack and Jacques Rousseau note that the subculture's focus on what it deems to be "cryptids" is a pseudoscientic extension of older belief in monsters and other similar entities from the folkloric record, yet with a "new, more scientific-sounding name: cryptids".
While biologists regularly identify new species, cryptozoologists often focus on creatures from the folkloric record. Most famously, these include the Loch Ness Monster, Bigfoot, the chupacabra, as well as other "imposing beasts that could be labeled as monsters". In their search for these entities, cryptozoologists may employ devices such as motion-sensitive cameras, night-vision equipment, and audio-recording equipment. While there have been attempts to codify cryptozoological approaches, unlike biologists, zoologists, botanists, and other academic disciplines, however, "there are no accepted, uniform, or successful methods for pursuing cryptids". Some scholars have identified precursors to modern cryptozoology in certain medieval approaches to the folkloric record, and the psychology behind the cryptozoology approach has been the subject of academic study.
Few cryptozoologists have a formal science education, and fewer still have a science background directly relevant to cryptozoology. Adherents often misrepresent the academic backgrounds of cryptozoologists. According to writer Daniel Loxton and paleontologist Donald Prothero, "[c]ryptozoologists have often promoted 'Professor Roy Mackal, PhD.' as one of their leading figures and one of the few with a legitimate doctorate in biology. What is rarely mentioned, however, is that he had no training that would qualify him to undertake competent research on exotic animals. This raises the specter of 'credential mongering', by which an individual or organization feints a person's graduate degree as proof of expertise, even though his or her training is not specifically relevant to the field under consideration." Besides Heuvelmans, Sanderson, and Mackal, other notable cryptozoologists with academic backgrounds include Grover Krantz, Karl Shuker, and Richard Greenwell.
Historically, notable cryptozoologists have often identified instances featuring "irrefutable evidence" (such as Sanderson and Krantz), only for the evidence to be revealed as the product of a hoax. This may occur during a closer examination by experts or upon confession of the hoaxer.
Cryptozoologists have often led expeditions to find evidence of their claims. Bigfoot researcher René Dahinden led unsuccessful expedition into caves to find evidence of sasquatch, which Daniel Loxton attributes to changes in the popular perception of bigfoot. Lensgrave Adam Christoffer Knuth led an expedition into Lake Tele in the Congo to find the Mokele-mbembe in 2018. While they found no evidence of the creature, they did find a new species of green algae.
A subset of cryptozoology promotes the pseudoscience of Young Earth creationism, rejecting conventional science in favor of a Biblical interpretation and promoting concepts such as "living dinosaurs". Science writer Sharon A. Hill observes that the Young Earth creationist segment of cryptozoology is "well-funded and able to conduct expeditions with a goal of finding a living dinosaur that they think would invalidate evolution".
Anthropologist Jeb J. Card says that "[c]reationists have embraced cryptozoology and some cryptozoological expeditions are funded by and conducted by creationists hoping to disprove evolution." In a 2013 interview, paleontologist Donald Prothero notes an uptick in creationist cryptozoologists. He observes that "[p]eople who actively search for Loch Ness monsters or Mokele Mbembe do it entirely as creationist ministers. They think that if they found a dinosaur in the Congo it would overturn all of evolution. It wouldn't. It would just be a late-occurring dinosaur, but that's their mistaken notion of evolution."
Citing a 2013 exhibit at the Petersburg, Kentucky-based Creation Museum, which claimed that dragons were once biological creatures who walked the earth alongside humanity and is broadly dedicated to Young Earth creationism, religious studies academic Justin Mullis notes that "[c]ryptozoology has a long and curious history with Young Earth Creationism, with this new exhibit being just one of the most recent examples".
Academic Paul Thomas analyzes the influence and connections between cryptozoology in his 2020 study of the Creation Museum and the creationist theme park Ark Encounter. Thomas comments that, "while the Creation Museum and the Ark Encounter are flirting with pseudoarchaeology, coquettishly whispering pseudoarchaeological rhetoric, they are each fully in bed with cryptozoology" and observes that "[y]oung-earth creationists and cryptozoologists make natural bed fellows. As with pseudoarchaeology, both young-earth creationists and cryptozoologists bristle at the rejection of mainstream secular science and lament a seeming conspiracy to prevent serious consideration of their claims."
Media outlets have often uncritically disseminated information from cryptozoologist sources, including newspapers that repeat false claims made by cryptozoologists or television shows that feature cryptozoologists as monster hunters (such as the popular and purportedly nonfiction American television show MonsterQuest, which aired from 2007 to 2010). Media coverage of purported "cryptids" often fails to provide more likely explanations, further propagating claims made by cryptozoologists.
There is a broad consensus among academics that cryptozoology is a pseudoscience. The subculture is regularly criticized for reliance on anecdotal information and because in the course of investigating animals that most scientists believe are unlikely to have existed, cryptozoologists do not follow the scientific method. No academic course of study nor university degree program grants the status of cryptozoologist and the subculture is primarily the domain of individuals without training in the natural sciences.
Anthropologist Jeb J. Card summarizes cryptozoology in a survey of pseudoscience and pseudoarchaeology:
Cryptozoology purports to be the study of previously unidentified animal species. At first glance, this would seem to differ little from zoology. New species are discovered by field and museum zoologists every year. Cryptozoologists cite these discoveries as justification of their search but often minimize or omit the fact that the discoverers do not identify as cryptozoologists and are academically trained zoologists working in an ecological paradigm rather than organizing expeditions to seek out supposed examples of unusual and large creatures.
Card notes that "cryptozoologists often show their disdain and even hatred for professional scientists, including those who enthusiastically participated in cryptozoology", which he traces back to Heuvelmans's early "rage against critics of cryptozoology". He finds parallels with cryptozoology and other pseudosciences, such as ghost hunting and ufology, and compares the approach of cryptozoologists to colonial big-game hunters, and to aspects of European imperialism. According to Card, "[m]ost cryptids are framed as the subject of indigenous legends typically collected in the heyday of comparative folklore, though such legends may be heavily modified or worse. Cryptozoology's complicated mix of sympathy, interest, and appropriation of indigenous culture (or non-indigenous construction of it) is also found in New Age circles and dubious "Indian burial grounds" and other legends [...] invoked in hauntings such as the "Amityville" hoax [...]".
In a 2011 foreword for The American Biology Teacher, then National Association of Biology Teachers president Dan Ward uses cryptozoology as an example of "technological pseudoscience" that may confuse students about the scientific method. Ward says that "Cryptozoology [...] is not valid science or even science at all. It is monster hunting." Historian of science Brian Regal includes an entry for cryptozoology in his Pseudoscience: A Critical Encyclopedia (2009). Regal says that "as an intellectual endeavor, cryptozoology has been studied as much as cryptozoologists have sought hidden animals".
In a 1992 issue of Folklore, folklorist Véronique Campion-Vincent says:
Unexplained appearances of mystery animals are reported all over the world today. Beliefs in the existence of fabulous and supernatural animals are ubiquitous and timeless. In the continents discovered by Europe indigenous beliefs and tales have strongly influenced the perceptions of the conquered confronted by a new natural environment. In parallel with the growing importance of the scientific approach, these traditional mythical tales have been endowed with sometimes highly artificial precision and have given birth to contemporary legends solidly entrenched in their territories. The belief self-perpetuates today through multiple observations enhanced by the media and encouraged (largely with the aim of gain for touristic promotion) by the local population, often genuinely convinced of the reality of this profitable phenomenon."
Campion-Vincent says that "four currents can be distinguished in the study of mysterious animal appearances": "Forteans" ("compiler[s] of anomalies" such as via publications like the Fortean Times), "occultists" (which she describes as related to "Forteans"), "folklorists", and "cryptozoologists". Regarding cryptozoologists, Campion-Vincent says that "this movement seems to deserve the appellation of parascience, like parapsychology: the same corpus is reviewed; many scientists participate, but for those who have an official status of university professor or researcher, the participation is a private hobby".
In her Encyclopedia of American Folklore, academic Linda Watts says that "folklore concerning unreal animals or beings, sometimes called monsters, is a popular field of inquiry" and describes cryptozoology as an example of "American narrative traditions" that "feature many monsters".
In his analysis of cryptozoology, folklorist Peter Dendle says that "cryptozoology devotees consciously position themselves in defiance of mainstream science" and that:
The psychological significance of cryptozoology in the modern world [...] serves to channel guilt over the decimation of species and destruction of the natural habitat; to recapture a sense of mysticism and danger in a world now perceived as fully charted and over-explored; and to articulate resentment of and defiance against a scientific community perceived as monopolising the pool of culturally acceptable beliefs.
In a paper published in 2013, Dendle refers to cryptozoologists as "contemporary monster hunters" that "keep alive a sense of wonder in a world that has been very thoroughly charted, mapped, and tracked, and that is largely available for close scrutiny on Google Earth and satellite imaging" and that "on the whole the devotion of substantial resources for this pursuit betrays a lack of awareness of the basis for scholarly consensus (largely ignoring, for instance, evidence of evolutionary biology and the fossil record)."
According to historian Mike Dash, few scientists doubt there are thousands of unknown animals, particularly invertebrates, awaiting discovery; however, cryptozoologists are largely uninterested in researching and cataloging newly discovered species of ants or beetles, instead focusing their efforts towards "more elusive" creatures that have often defied decades of work aimed at confirming their existence.
Paleontologist George Gaylord Simpson (1984) lists cryptozoology among examples of human gullibility, along with creationism:
Humans are the most inventive, deceptive, and gullible of all animals. Only those characteristics can explain the belief of some humans in creationism, in the arrival of UFOs with extraterrestrial beings, or in some aspects of cryptozoology. [...] In several respects the discussion and practice of cryptozoology sometimes, although not invariably, has demonstrated both deception and gullibility. An example seems to merit the old Latin saying 'I believe because it is incredible,' although Tertullian, its author, applied it in a way more applicable to the present day creationists.
Paleontologist Donald Prothero (2007) cites cryptozoology as an example of pseudoscience and categorizes it, along with Holocaust denial and UFO abductions claims, as aspects of American culture that are "clearly baloney".
In Scientifical Americans: The Culture of Amateur Paranormal Researchers (2017), Hill surveys the field and discusses aspects of the subculture, noting internal attempts at creating more scientific approaches and the involvement of Young Earth creationists and a prevalence of hoaxes. She concludes that many cryptozoologists are "passionate and sincere in their belief that mystery animals exist. As such, they give deference to every report of a sighting, often without critical questioning. As with the ghost seekers, cryptozoologists are convinced that they will be the ones to solve the mystery and make history. With the lure of mystery and money undermining diligent and ethical research, the field of cryptozoology has serious credibility problems."
Cryptobotany is a sub-discipline of cryptozoology researching the possible existence of plant cryptids. According to British cryptozoologist Karl Shuker's 2003 book The Beasts That Hide From Man there are unconfirmed reports, primarily from Latin America, of still-undiscovered species of large carnivorous plants.
There have been several organizations, of varying types, dedicated or related to cryptozoology. These include:
The zoological and cryptozoological collection and archive of Bernard Heuvelmans is held at the Musée Cantonal de Zoologie in Lausanne and consists of around "1,000 books, 25,000 files, 25,000 photographs, correspondence, and artifacts".
In 2006, the Bates College Museum of Art held the "Cryptozoology: Out of Time Place Scale" exhibition, which compared cryptozoological creatures with recently extinct animals like the thylacine and extant taxa like the coelacanth, once thought long extinct (living fossils). The following year, the American Museum of Natural History put on a mixed exhibition of imaginary and extinct animals, including the elephant bird Aepyornis maximus and the great ape Gigantopithecus blacki, under the name "Mythic Creatures: Dragons, Unicorns and Mermaids".
In 2003 cryptozoologist Loren Coleman opened the International Cryptozoology Museum in Portland, Maine. The museum houses more than 3000 cryptozoology related artifacts. | [

] | Cryptozoology is a pseudoscience and subculture that searches for and studies unknown, legendary, or extinct animals whose present existence is disputed or unsubstantiated, particularly those popular in folklore, such as Bigfoot, the Loch Ness Monster, Yeti, the chupacabra, the Jersey Devil, or the Mokele-mbembe. Cryptozoologists refer to these entities as cryptids, a term coined by the subculture. Because it does not follow the scientific method, cryptozoology is considered a pseudoscience by mainstream science: it is neither a branch of zoology nor of folklore studies. It was originally founded in the 1950s by zoologists Bernard Heuvelmans and Ivan T. Sanderson. Scholars have noted that the subculture rejected mainstream approaches from an early date, and that adherents often express hostility to mainstream science. Scholars have studied cryptozoologists and their influence, noted parallels in cryptozoology and other pseudosciences such as ghost hunting and ufology, and highlighted uncritical media propagation of cryptozoologist claims. | 2001-10-28T13:11:02Z | 2023-12-21T18:27:53Z | [

5,829 | Craig Charles | Craig Joseph Charles (born 11 July 1964) is an English actor, comedian, DJ, and television and radio presenter. He is best known for his roles as Dave Lister in the science fiction sitcom Red Dwarf and Lloyd Mullaney in the soap opera Coronation Street (2005–2015). He presented the gladiator-style game show Robot Wars from 1998 to 2004, and narrated the comedy endurance show Takeshi's Castle. As a DJ, he appears on BBC Radio 6 Music.
Charles first appeared on television as a performance poet, which led to minor presenting roles. After finding fame in Red Dwarf, he regularly featured on national television with celebrity appearances on many popular shows while he continued to host a wide variety of programmes. From 2017 to 2022, Charles hosted The Gadget Show for Channel 5. His acting credits include playing inmate Eugene Buffy in the ITV drama The Governor, and leading roles in the British films Fated and Clubbing to Death.
Charles has hosted The Craig Charles Funk and Soul Show on BBC radio since 2002, and performs DJ sets at numerous clubs and festivals, nationally and internationally. In September 2015, he left Coronation Street after ten years of acting, to film new episodes of Red Dwarf and to continue his BBC Radio 6 Music and BBC Radio 2 broadcasting.
Craig Joseph Charles was born in Liverpool on 11 July 1964, the son of a Guyanese father and Irish mother. He grew up on the Cantril Farm housing estate with his older brother, Dean (died 2014), and two other brothers, Jimmy and Emile. He attended West Derby Comprehensive School followed by Childwall Hall College of Further Education, studying A-levels in History, Government & Politics, English Literature and General Studies. He won a national competition run by The Guardian newspaper for a poem he wrote when he was 12 years old. Upon leaving school, Charles spent time working in a studio at Central Hall on Renshaw Street in Liverpool.
Charles began his career as a contemporary and urban performance poet on the British cabaret circuit. His performances were considered original, with Charles described as having a natural ironic wit which appealed to talent scouts. In 1981, Charles climbed on stage at a Teardrop Explodes concert and recited a humorous, but derogatory, poem about the band's singer, Julian Cope. He was invited to open subsequent gigs for the group and went on to perform as a support act in pubs and clubs for the following three years, and at events such as the Larks in the Park music festival at Sefton Park (1982). He performed poetry reading poems by Vladimir Mayakovsky, W. H. Auden and E. E. Cummings, at Liverpool's Everyman Theatre (1983), with such poets as Roger McGough and Adrian Henri.
Charles was involved in the Liverpool music scene, writing and singing lyrics for a number of local rock bands. In 1980, he played keyboards, bass and provided voice in the rock band Watt 4. He performed his political rap lyrics as a 'Wordsmith'. In 1983, Charles was invited to record a session on the John Peel BBC Radio show, performing his poems backed by a band. This was his first professional engagement. He recorded a further Peel Session in 1984.
Charles realised he was using poetry as a vehicle for his sense of humour and progressed into stand-up comedy. He was part of the Red Wedge comedy tour in 1986, which aimed to raise awareness of the social problems of the time, in support of the Labour Party. He also performed his first one-man show in 1986, which premiered in Edinburgh, and then toured internationally. Charles was a guest on programmes including Janice Long's Radio 1 show, and he was a regular panellist on Ned Sherrin's chat show Loose Ends (1987–88) on BBC Radio 4.
Charles first appeared on television as the resident poet on the arts programme Riverside on BBC2 and on the day-time BBC1 chat show Pebble Mill at One. Charles was the resident poet on the Channel 4 programme Black on Black (1985) and its entertainment-based successor Club Mix (1986), and he appeared, weekly, as a John Cooper Clarke-style 'punk poet' on the BBC2 pop music programme Oxford Road Show (ORS). Charles performed his political poems as stand-up comedy on the late-night show Saturday Live (1985–87) and on the prime-time BBC1 chat show Wogan (1986–87), where he performed a topical poem in a weekly feature. He also appeared as a guest on shows including Open Air (1988). Charles included significant acting in his performance style, enabling him to put the emotion across. In September 2015, Charles performed his "epic" poem Scary Fairy and the Tales of the Dark Wood live with the BBC Philharmonic orchestra, in a concert to be broadcast on BBC Radio 2's Friday Night Is Music Night at Halloween.
Charles' first television acting role was the Liverpudlian slob Dave Lister in science fiction comedy series Red Dwarf. He was introduced to the show by Saturday Live and Red Dwarf producer Paul Jackson, who wanted his opinion on whether the black character Cat was a racist stereotype. Charles, who like all of the eventual main cast had no acting experience, was eventually offered an audition after begging Jackson.
Charles has appeared in all twelve series as well as Red Dwarf: The Promised Land. Charles' younger brother, Emile Charles, guest-starred in the third-series episode "Timeslides", and the songs "Bad News" and "Cash" in this episode were written by Charles and performed by his band. The role has involved Charles playing a variety of alternative characters, including a gangster, a cowboy and angelic and evil versions of Lister, and in him carrying out a wide range of stunts, and acting involving special effects. All series, except 7 and 9, were recorded in front of a studio audience. Along with Danny John-Jules (Cat), Charles is one of only two cast members to appear in every episode of Red Dwarf to date.
Charles reads the audiobook editions of both the Red Dwarf novel Last Human and his book The Log: A Dwarfer's Guide to Everything, and he regularly attends sci-fi, comedy and memorabilia conventions in connection with the Red Dwarf franchise. During Back to Earth, Lister visits the set of Coronation Street, where he meets the actor Craig Charles.
Charles presented Robot Wars on BBC2 (1998–2003) and Channel 5 (2003–04), from series 2 until series 7, which included two Extreme series and numerous 'specials'. Charles was the main host and presided over the arena in which teams of amateur engineers battled their home-made radio-controlled robots against each other, and against the house robots. Charles introduced the show, enthusiastically announced the results of the battles and spoke to the contestants after the main events. He ended each episode with a short Robot Wars-themed poem. Charles' son, Jack, appeared on the show on several occasions, and was a contestant on "Team Nemesis" during series 4. Charles also hosted the Robot Wars Live UK tour, in 2001 and shows performed at the Wembley Arena.
Robot Wars returned to the BBC in 2016. Charles stated his interest in hosting it again, but the job went to Dara Ó Briain and Angela Scanlon.
Charles provided the English voice-over commentary for the Challenge (2002–04) rebroadcast of the popular game show Takeshi's Castle, originally by Tokyo Broadcasting System in Japan. In each episode, between 100 and 142 contestants attempted to pass a series of wacky and near-impossible physical challenges to reach the Show Down at the castle against Japanese actor Takeshi Kitano for a chance to win large cash prizes. Charles co-wrote the programme and commentated throughout all 122 episodes of the four series, and also some special and "best of" episodes. He provided comedy insights into the contestants' abilities, which were designed to appeal to adult audiences, as well as younger viewers - and also coined the term "Keshi Heads" to describe fans of the show. A 2013 reboot narrated by Dick and Dom was not as well received.
In 2005, Charles joined the main cast of Coronation Street, playing a philandering taxicab driver, Lloyd Mullaney. Charles introduced aspects of the character himself, making Lloyd a Northern Soul DJ and record collector, and funk music enthusiast. Charles has chosen funk and soul songs playing as backing tracks during scenes, and posters for The Craig Charles Funk & Soul Club and Red Dwarf have appeared in the background.
Charles portrayed Lloyd as tough, but kind-hearted and romantic, and the character was popular with viewers. Charles added a comedy element to the role, but was also involved in traumatic and emotional scenes with intricate storylines. In 2010, his character was involved in the show's dramatic 50th anniversary tram crash storyline, which was broadcast live. Charles presented documentaries for the show, including 50 Years of Corrie Stunts (2010), which is included on the Tram Crash DVD. In November 2011, Charles took time off from Coronation Street to film a new series of Red Dwarf, returning in April 2012. In February 2014 an online mini-series, Steve & Lloyd's Streetcar Stories, ran alongside the television show's storyline.
In May 2015, Craig announced he would be leaving Coronation Street for Red Dwarf, BBC Radio 2 and BBC Radio 6 Music. Lloyd left in a red Cadillac during the live episode on 23 September, although his final pre-recorded farewell scenes with Steve were shown during the following episode.
Charles has acted in episodes of popular dramas such as The Bill (1995), EastEnders (2002) and Holby City (2003) and in the comedy The 10 Percenters (1996). Charles played the emotionally disturbed and violent prisoner, Eugene Buffy, in the highly successful Lynda La Plante drama series The Governor (1996); the title role in the Channel 4 pirate sitcom Captain Butler (1997); the warden of a women's prison in the Canadian sci-fi fantasy Lexx (2001); Detective Chief Inspector Mercer in seven episodes of the BBC soap opera Doctors (2003); and soccer agent, Joel Brooks, in the Sky TV football soap Dream Team (2004).
Charles has presented children's television programmes, including What's That Noise? (1989) and Parallel 9 (1992) on BBC1 and Go Getters (1994) on ITV. He was the travelling reporter for the highly acclaimed, but controversial, BBC 'mockumentary' Ghostwatch, which tricked viewers into believing it was a live investigation into ghost sightings in a suburban home on Halloween night (1992). Charles presented the virtual reality game show Cyberzone (1993) on BBC2; the late-night entertainment show Funky Bunker (1997) on ITV; the reality show Jailbreak (2000) on Channel 5; the discussion show Amazing Space: The Pub Guide to the Universe (2001) on National Geographic; and the late-night current affairs chat show Weapons of Mass Distraction (2004) on ITV.
Charles has appeared on celebrity editions of University Challenge (1998), Can't Cook, Won't Cook (1998), The Weakest Link (2004), The Chase (2012) and Pointless (2013), and comedy panel shows such as Have I Got News for You (1995), Just a Minute (1995) and They Think It's All Over (1996) and Keith Lemon's Through the Keyhole (2014). He was a team captain on the sci-fi quiz series Space Cadets (1997) on Channel 4, which guest-starred William Shatner. Charles has opened The National Lottery Draw (1997) and his home has featured on Through the Keyhole. Charles was a contestant in the Celebrity Poker Club tournament (2004) on Challenge, where he reached the semi-finals, and in the Channel 4 reality game show, The Games (2005), which documented the contestants' intensive training regime and each live Olympic Games-style sporting event.
From 16 November 2014, Charles took part in the fourteenth series of I'm a Celebrity...Get Me Out of Here! However, on 20 November, Charles left the series soon after learning that his brother Dean had died after suffering a heart attack.
As well as his early appearances on shows such as Radio 4's Loose Ends (1987–88) and Kaleidoscope in the early 1990s, Charles could be heard on the London Radio Station Kiss 100 (Kiss FM) as the Breakfast show presenter. In 1995, Charles played the Porter in Steven Berkoff's adaptation of Shakespeare's Macbeth, on Radio 4.
Since 2002, Charles has been a DJ on BBC Radio 6 Music presenting The Craig Charles Funk and Soul Show, on air on Saturday evenings 6 pm to 9 pm, where he plays a diverse range of funk and soul music, from classic tracks to the latest releases, and provides publicity for less familiar bands. Charles explains the context for the music and carries out interviews with guest musicians. He was with the station at its launch, and while it was being tested during the previous year, under the name Network Y. Charles has also hosted the station's Breakfast Show (2004), and sits in for other presenters including Andrew Collins, Phil Wilding, Phill Jupitus, and Radcliffe & Maconie.
From January until November 2014, Charles also broadcast The Funk and Soul Show live on BBC Radio 2, immediately after his 6 Music show. He regularly sits in for various presenters, and has presented numerous programmes on the station, including The Craig Charles Soul All-Nighter (2011), which he hosted continuously for 12 hours, and the Beatleland (2012) documentary on The Beatles. Charles has also chosen music as a guest of other broadcasters such as Ken Bruce on Radio 2 and Liz Kershaw on 6 Music. Charles covered for Graham Norton on Radio 2's Saturday mid-morning show during Norton's 10-week 2015 summer break. From 16 April 2016 until 18 June 2022, Charles presented the House Party on Saturday nights on BBC Radio 2, with the show airing between 10 pm and midnight. For eight weeks from April–June 2020, he also presented Craig Charles At Teatime between 4 pm and 7 pm on weekdays on Radio 6 Music. The show was sometimes billed as Craig Charles Weekend Workout on Fridays.
Since 18 October 2021, Charles has hosted the weekday afternoon show on BBC Radio 6 Music (1 pm – 4 pm). The shows include the "Trunk of Punk" and the "Jar of Ska".
Charles has been involved in the music industry through much of his career. His bands have included Watt 4 (1980), in which he played keyboards and sang; Craig Charles and the Beat Burglars (1989); The Sons of Gordon Gekko (1989), where he wrote lyrics and also composed tunes; and The Eye (2000–02), with whom he recorded the rock album Giving You the Eye, Live at the Edinburgh Festival. Charles plays guitar and piano.
In 1987, Charles provided the poem track used for the opening credits of the BBC series The Marksman (in which he also acted), which is included on the album "The Marksman: Music from the BBC TV Series". Charles wrote lyrics for Suzanne Rhatigan's album To Hell with Love (1992). In 1993, Charles was signed to the Acid Jazz record label.
In 2009, Charles formed the Fantasy Funk Band from the leading British musicians in the genre, and has presented the band at festivals, including Glastonbury and the BBC's Proms in the Park. As a continuation of his 6 Music show, Charles regularly takes the Craig Charles Funk & Soul Club to varied venues across the UK and abroad, and to the major UK music festivals. He performs live DJ sets, occasionally comperes and curates events, including his own Craig Charles Fantasy Weekender, and has broadcast the radio show live from festival locations.
In 2012, Charles released the compilation album The Craig Charles Funk & Soul Club, on CD and as a digital download, as part of a three-album deal with Freestyle Records. The second volume was released in the same format in 2013, and the third in 2014. He followed these with a Craig Charles Funk and Soul Classics album of three CDs in 2015.
Charles returned to stand-up comedy between 1995 and 2001, regularly touring his one-man adult-rated shows nationally and releasing the videos Craig Charles: Live on Earth! (1995), Live Official Bootleg (1996) and Sickbag (2000). International performances included the Great Norwegian Comedy Festival and the Melbourne International Comedy Festival.
Charles appeared in the John Godber comedy play Teechers, in which he swapped in and out of various roles, at the Arts Theatre, London, and at the Edinburgh Festival (1989), and he played Idle Jack in the pantomime Dick Whittington, at the Hull New Theatre (1997). In 2000, he performed the show Craig Charles and His Band at the Edinburgh Festival.
Charles has a regular slot at Butlins Minehead House Of Fun Weekend every third November for three nights, of DJing, Comedy, Twanging and singing.
Charles played Eddie in the 1987 political drama Business as Usual. In 2006, Charles starred in two British feature films: the fantasy film Fated and the gangster film Clubbing to Death. Charles voiced Zipper the Cat in the animation Prince Cinders (1993) and Asterix in Asterix Conquers America (1994). Roles in short films include playing Keith Dennis in the comedy The Colour of Funny (1999) and Mark in the drama Ten Minutes (2004).
In 1993, Charles worked with Russell Bell on the Craig Charles Almanac of Total Knowledge, writing about his 'streetwise' sense of humour on a range of topics, from the world's most embarrassing stories to how to explain the mysteries of the universe. In 1997, Charles and Bell wrote Charles' Red Dwarf character's book The Log, in which Lister decides to leave a log detailing mankind's greatest achievements. In 1998, Charles published No Other Blue, a collection of his poetry, with illustrations by Philippa Drakeford, on diverse personal subjects including prison, his mother's final illness, love and politics at home and abroad. More recently he has written a series of nursery rhymes titled "Scary Fairy and the Tales of the Dark Wood".
In 2000, Charles wrote his first autobiography about his experiences growing up in Liverpool, titled No Irish, No Niggers. In 2007, he announced he would release his autobiography, planned for March 2008, published by Hodder Headline and titled On the Rocks, which would cover the recent incidents in his life and be based on much of his journal, which Charles said he kept while in rehab.
Charles has been involved in journalism and has had a column in Time Out magazine. In 1994, he launched a single issue of Comedy magazine with articles dedicated to the comedy circuit. In 2005 and 2006, Charles was a monthly columnist for the Liverpool Echo newspaper. His television writing credits include The Easter Stories (1994), Funky Bunker (1997) and Takeshi's Castle (2002). He is also involved in music journalism as he wrote liner notes for the funk and soul music producer Mr. Confuse for his albums Feel The Fire (2008), Do You Realize (2012) and Only A Man (2018) regarding his work as a music presenter for The Craig Charles Funk and Soul Show on BBC Radio 6 Music.
Charles resides in Altrincham, Greater Manchester. He has three children: a son named Jack from his first marriage to actress Cathy Tyson, and two daughters named Anna-Jo and Nellie from his second marriage to Jackie Fleming.
In July 1994, Charles and another man were charged with rape and four counts of indecent assault, following allegations by an associate and ex-girlfriend of Charles. Charles was remanded in custody for three-and-a-half months before being granted bail, during which time he was assaulted by a man wielding a makeshift knife. In March 1995, Charles and his co-accused were acquitted of all charges at trial. After being acquitted, Charles spoke of the need to restore anonymity for those accused of rape. He stated, "The fact that my name and address along with my picture can appear on the front of the papers before the so-called 'victim' has even signed a statement proves that anonymity for rape defendants is a must and that the law must be changed."
Charles has battled drug addiction—he described himself in 2015 as "quite an addictive person", trying to find healthier addictions, of which work was one. In June 2006, newspaper allegations of crack cocaine use resulted in Charles being suspended from both Coronation Street and BBC Radio 6 Music. In August, Charles was arrested and released on bail pending further enquiries, and in September he accepted a caution for possession of a Class A drug. Charles returned to hosting his 6 Music show from November 2006 and filming Coronation Street from January 2007. In a 2015 interview, Charles spoke of his need to remain "vigilant" in abstaining from drugs. In 2020 he said that the newspaper reports were the best thing that could have happened to him, leading him to join Narcotics Anonymous and straighten out his personal life. | [

Charles co-wrote the programme and commentated throughout all 122 episodes of the four series, and also some special and \"best of\" episodes. He provided comedy insights into the contestants' abilities, which were designed to appeal to adult audiences, as well as younger viewers - and also coined the term \"Keshi Heads\" to describe fans of the show.

5,830 | County Mayo | County Mayo (/ˈmeɪoʊ/; from Irish Mhaigh Eo, meaning 'Plain of the yew trees') is a county in Ireland. In the West of Ireland, in the province of Connacht, it is named after the village of Mayo, now generally known as Mayo Abbey. Mayo County Council is the local authority. The population was 137,231 at the 2022 census. The boundaries of the county, which was formed in 1585, reflect the Mac William Íochtar lordship at that time.
It is bounded on the north and west by the Atlantic Ocean; on the south by County Galway; on the east by County Roscommon; and on the northeast by County Sligo. Mayo is the third-largest of Ireland's 32 counties in area and 18th largest in terms of population. It is the second-largest of Connacht's five counties in both size and population. Mayo has 1,168 km (726 mi) of coastline, or approximately 21% of the total coastline of the State. It is one of three counties which claims to have the longest coastline in Ireland, alongside Cork and Donegal. There is a distinct geological difference between the west and the east of the county. The west consists largely of poor subsoils and is covered with large areas of extensive Atlantic blanket bog, whereas the east is largely a limestone landscape. Agricultural land is therefore more productive in the east than in the west.
There are nine historic baronies, four in the northern area and five in the south of the county:
North Mayo
South Mayo
According to the 2022 census:
A survey of the terrestrial and freshwater algae of Clare Island was made between 1990 and 2005 and published in 2007. A record of Gunnera tinctoria is also noted.
Consultants working for the Corrib gas project have carried out extensive surveys of wildlife flora and fauna in Kilcommon Parish, Erris between 2002 and 2009. This information is published in the Corrib Gas Proposal Environmental impact statements 2009 and 2010.
There is evidence of human occupation of what is now County Mayo going far back into prehistory. At Belderrig on the north Mayo coast, there is evidence for Mesolithic (Middle Stone Age) communities around 4500 BC. while throughout the county there is a wealth of archaeological remains from the Neolithic (New Stone Age) period (ca. 4,000 BC to 2,500 BC), particularly in terms of megalithic tombs and ritual stone circles.
The first people who came to Ireland – mainly to coastal areas as the interior was heavily forested – arrived during the Middle Stone Age, as far back as eleven thousand years ago. Artefacts of hunter/gatherers are sometimes found in middens, rubbish pits around hearths where people would have rested and cooked over large open fires. Once cliffs erode, midden remains become exposed as blackened areas containing charred stones, bones, and shells. They are usually found a metre below the surface. Mesolithic people did not have major rituals associated with burial, unlike those of the Neolithic (New Stone Age) period. The Neolithic period followed the Mesolithic around 6,000 years ago. People began to farm the land, domesticate animals for food and milk, and settle in one place for longer periods. These people had skills such as making pottery, building houses from wood, weaving, and knapping (stone tool working). The first farmers cleared forestry to graze livestock and grow crops. In North Mayo, where the ground cover was fragile, thin soils washed away and blanket bog covered the land farmed by the Neolithic people.
Extensive pre-bog field systems have been discovered under the blanket bog, particularly along the North Mayo coastline in Erris and north Tyrawley at sites such as the Céide Fields, centred on the northeast coast.
The Neolithic people developed rituals associated with burying their dead; this is why they built huge, elaborate, galleried stone tombs for their dead leaders, known nowadays as megalithic tombs. There are over 160 recorded megaliths in County Mayo, such as Faulagh.
There are four distinct types of Irish megalithic tombs—court tombs, portal tombs, passage tombs and wedge tombs—examples of all of which can be found in County Mayo. Areas particularly rich in megalithic tombs include Achill, Kilcommon, Ballyhaunis, Moygownagh, Killala and the Behy/Glenurla area around the Céide Fields.
Megalithic tomb building continued into the Bronze Age when metal began to be used for tools alongside the stone tools. The Bronze Age lasted approximately from 4,500 years ago to 2,500 years ago (2,500 BC to 500 BC). Archaeological remains from this period include stone alignments, stone circles and fulachta fiadh (early cooking sites). They continued to bury their chieftains in megalithic tombs which changed design during this period, more being of the wedge tomb type and cist burials.
Around 2,500 years ago the Iron Age took over from the Bronze Age as more and more metalworking took place. This is thought to have coincided with the arrival of Celtic speaking peoples and the introduction of the ancestor of the Irish language. Towards the end of this period, the Roman Empire was at its height in Britain but it is not thought that the Roman Empire extended into Ireland. Remains from this period, which lasted until the Early Christian period began about AD 325 (with the arrival of Saint Patrick into Ireland, as a slave) include crannógs (Lake dwellings), promontory forts, ringforts and souterrains of which there are numerous examples across the county. The Iron Age was a time of tribal warfare and kingships, each fighting neighbouring kings, vying for control of territories and taking slaves. Territories were marked by tall stone markers, Ogham stones, using the first written down words using the Ogham alphabet. The Iron Age is the time period in which the mythological tales of the Ulster Cycle and sagas took place, as well as that of the Táin Bó Flidhais, whose narrative is set in mainly in Erris.
Christianity came to Ireland around the start of the 5th century. It brought many changes including the introduction of the Latin alphabet. The tribal 'tuatha' and new Christian religious settlements existed side by side. Sometimes it suited the chieftains to become part of the early Churches, other times they remained as separate entities. St. Patrick (4th century) may have spent time in County Mayo and it is believed that he spent forty days and forty nights on Croagh Patrick praying for the people of Ireland. From the middle of the 6th-century hundreds of small monastic settlements were established around the county. Some examples of well-known early monastic sites in Mayo include Mayo Abbey, Aughagower, Ballintubber, Errew Abbey, Cong Abbey, Killala, Turlough on the outskirts of Castlebar, and island settlements off the Mullet Peninsula like the Inishkea Islands, Inishglora and Duvillaun.
In 795 the first of the Viking raids took place. The Vikings came from Scandinavia to raid the monasteries as they were places of wealth with precious metal working taking place in them. Some of the larger ecclesiastical settlements erected round towers to prevent their precious items from being plundered and also to show their status and strength against these pagan raiders from the north. There are round towers at Aughagower, Balla, Killala, Turlough and Meelick. The Vikings established settlements that later developed into towns (Dublin, Cork, Wexford, Waterford etc.) but none were in County Mayo. Between the reigns of Kings of Connacht Cathal mac Conchobar mac Taidg (973–1010) and Tairrdelbach Ua Conchobair (1106–1156), various tribal territories were incorporated into the kingdom of Connacht and ruled by the Siol Muirdaig dynasty, based initially at Rathcroghan in County Roscommon, and from c. 1050 at Tuam. The families of O'Malley and O'Dowd of Mayo served as admirals of the fleet of Connacht, while families such as O'Lachtnan, Mac Fhirbhisigh, and O'Cleary were ecclesiastical and bardic clans.
In AD 1169 when one of the warring kings in the east of Ireland, Dermot MacMurrough, appealed to the King of England for help in his fight with a neighbouring king, the response resulted in the Anglo-Norman colonisation of Ireland. County Mayo came under Norman control in AD 1235. Norman control meant the eclipse of many Gaelic lords and chieftains, chiefly the O'Connors of Connacht. During the 1230s, the Anglo-Normans and Welsh under Richard Mór de Burgh (c. 1194 – 1242) invaded and settled in the county, introducing new families such as Burke, Gibbons, Staunton, Prendergast, Morris, Joyce, Walsh, Barrett, Lynott, Costello, Padden and Price, Norman names are still common in County Mayo. Following the collapse of the lordship in the 1330s, all these families became estranged from the Anglo-Irish administration based in Dublin and assimilated with the Gaelic-Irish, adopting their language, religion, dress, laws, customs and culture and marrying into Irish families. They became "more Irish than the Irish themselves".
The most powerful clan to emerge during this era were the Mac William Burkes, also known as the Mac William Iochtar (see Burke Civil War 1333–1338), descended from Sir William Liath de Burgh, who defeated the Gaelic-Irish at the Second Battle of Athenry in August 1316. They were frequently at war with their cousins, Clanricarde of Galway, and in alliance with or against various factions of the O'Conor's of Siol Muiredaig and O'Kelly's of Uí Maine. The O'Donnell's of Tyrconnell regularly invaded in an attempt to secure their right to rule.
The Anglo-Normans encouraged and established many religious orders from continental Europe to settle in Ireland. Mendicant orders—Augustinians, Carmelites, Dominicans and Franciscans began new settlements across Ireland and built large churches, many under the patronage of prominent Gaelic families. Some of these sites include Cong, Strade, Ballintubber, Errew Abbey, Burrishoole Abbey and Mayo Abbey. During the 15th and 16th centuries, despite regular conflicts between them as England chopped and changed between religious beliefs, the Irish usually regarded the King of England as their King. When Elizabeth I came to the throne in the mid-16th century, the English people, as was customary at that time, followed the religious practices of the reigning monarch and became Protestant. Many Irish people such as Grace O'Malley, the famous pirate queen, had close relationships with the English monarchy, and the English kings and queens were welcome visitors to Irish shores. The Irish however, generally held onto their Catholic religious practices and beliefs. The early plantations of settlers in Ireland began during the reign of Queen Mary in the mid-16th century and continued throughout the long reign of Queen Elizabeth I until 1603. By then the term County Mayo had come into use. In the summer of 1588, the galleons of the Spanish Armada were wrecked by storms along the west coast of Ireland. Some of the hapless Spaniards came ashore in Mayo, only to be robbed and imprisoned, and in many cases slaughtered.
Almost all the religious foundations set up by the Anglo-Normans were suppressed in the wake of the Reformation in the 16th century.
Protestant settlers from Scotland, England, and elsewhere in Ireland, settled in the County in the early 17th century. Many would be killed or forced to flee because of the 1641 Rebellion, during which a number of massacres were committed by the Catholic Gaelic Irish, most notably at Shrule in 1642. A third of the overall population was reported to have perished due to warfare, famine and plague between 1641 and 1653, with several areas remaining disturbed and frequented by Reparees into the 1670s.
Pirate Queen Grace O'Malley is probably the best-known person from County Mayo between the mid-16th century and the turn of the 17th century. In the 1640s, when Oliver Cromwell overthrew the English monarchy and set up a parliamentarian government, Ireland suffered severely. With a stern regime in absolute control needing to pay its armies and allies, the need to pay them with grants of land in Ireland led to the 'to hell or to Connaught' policies. Displaced native Irish families from other (eastern and southern mostly) parts of the country were either forced to leave the country or were awarded grants of land 'west of the Shannon' and put off their own lands in the east. The land in the west was divided and sub-divided between more and more people as huge estates were granted on the best land in the east to those who best pleased the English. Mayo does not seem to have been affected much during the Williamite War in Ireland, though many natives were outlawed and exiled.
For the vast majority of people in County Mayo the 18th century was a period of unrelieved misery. Because of the penal laws, Catholics had no hope of social advancement while they remained in their native land. Some, like William Brown (1777–1857), left Foxford with his family at the age of nine and thirty years later was an admiral in the fledgeling Argentine Navy. Today he is a national hero in that country.
The general unrest in Ireland was felt just as keenly across Mayo, and as the 19th century approached and news reached Ireland about the American War of Independence and the French Revolution, the downtrodden Irish, constantly suppressed by Government policies and decisions from Dublin and London, began to rally themselves for their own stand against British rule in their country. 1798 saw Mayo become a central part of the United Irishmen Rebellion when General Humbert from France landed in Killala with over 1,000 soldiers playing to support the main uprising. They marched across the county towards the administrative centre of Castlebar, leading to the Battle of Castlebar. Taking the garrison by surprise Humbert's army was victorious. He established a ' Republic of Connacht' with John Moore of the Moore family from Moore Hall near Partry as its head. Humbert's army marched on towards Sligo, Leitrim and Longford where they were suddenly faced with a massive British army and were forced to surrender in less than half an hour. The French soldiers were treated honourably, but for the Irish the surrender meant slaughter. Many died on the scaffold in towns like Castlebar and Claremorris, where the high sheriff for County Mayo, the Honourable Denis Browne, M.P., brother of Lord Altamont, wreaked a terrible vengeance – thus earning for himself the nickname which has survived in folk memory to the present day, 'Donnchadh an Rópa' (Denis of the Rope).
In the 18th century and early 19th century, sectarian tensions arose as evangelical Protestant missionaries sought to 'redeem the Irish poor from the errors of Popery'. One of the best known was the Rev. Edward Nangle's mission at Dugort in Achill. These too were the years of the campaign for Catholic Emancipation and, later, for the abolition of the tithes, which a predominately Catholic population was forced to pay for the upkeep of the clergy of the Established (Protestant) Church.
During the early years of the 19th century, famine was a common occurrence, particularly where population pressure was a problem. The population of Ireland grew to over eight million people prior to the Irish Famine (or Great Famine) of 1845–47. The Irish people depended on the potato crop for their sustenance. Disaster struck in August 1845, when a killer fungus (later diagnosed as Phytophthora infestans) started to destroy the potato crop. When widespread famine struck, about a million people died and a further million left the country. People died in the fields of starvation and disease. The catastrophe was particularly bad in County Mayo, where nearly ninety per cent of the population depended on the potato as their staple food. By 1848, Mayo was a county of total misery and despair, with any attempts at alleviating measures in complete disarray.
There are numerous reminders of the Great Famine to be seen on the Mayo landscape: workhouse sites, famine graves, sites of soup kitchens, deserted homes and villages and even traces of undug 'lazy-beds' in fields on the sides of hills. Many roads and lanes were built as famine relief measures. There were nine workhouses in the county: Ballina, Ballinrobe, Belmullet, Castlebar, Claremorris, Killala, Newport, Swinford and Westport.
A small poverty-stricken place called Knock, County Mayo, made headlines when it was announced that an apparition of the Blessed Virgin Mary, St. Joseph and St. John had taken place there on 21 August 1879, witnessed by fifteen local people.
A national movement was initiated in County Mayo during 1879 by Michael Davitt, James Daly, and others, which brought about a major social change in Ireland. Michael Davitt, a labourer whose family had moved to England joined forces with Charles Stewart Parnell to win back the land for the people from the landlords and stop evictions for non-payment of rents. The organisation became known as the Irish National Land League, and its struggle to win rights for poor farmers in Ireland was known as the Land War.
It was in this era of agrarian unrest that a new verb was introduced to the English language by Mayo - "to boycott". Charles Boycott was an English landlord deeply unpopular with his tenants. When Charles Steward Parnell made a speech in Ennis, County Clare, urging nonviolent resistance against landlords, his tactics were enthusiastically taken in Mayo against Boycott. The entire Catholic community around Lough Mask in South Mayo where Boycott had his estate became a campaign of total social ostracisation against Boycott, a tactic that would one day come to bear his name. The campaign against Boycott became a cause célèbre in the British press after he wrote a letter to The Times. The British elite rallied to his cause and Fifty Orangemen from County Cavan and County Monaghan travelled to his estate to harvest the crops, while a regiment of the 19th Royal Hussars and more than 1,000 men of the Royal Irish Constabulary were deployed to protect the harvesters. However, the cost of doing this was completely uneconomic: It cost the British government somewhere in the region of £10,000 to simply harvest £500 worth of crops. Boycott sold off the estate and the British government's resolve to try to break boycotts in this completely dissolved, resulting in victory for the tenants.
The "Land Question" was gradually resolved by a scheme of state-aided land purchase schemes. The tenants became the owners of their lands under the newly set-up Land Commission.
A Mayo nun, Mother Agnes Morrogh-Bernard, set up the Foxford Woollen Mill in 1892. She made Foxford synonymous throughout the world with high-quality tweeds, rugs and blankets.
Mayo, as all parts of what became the Irish Free State, was affected by the events of the Irish revolutionary period, including the Irish War of Independence and the subsequent Irish Civil War. Major John MacBride of Westport was amongst those who took part in the 1916 Easter Rising and was subsequently executed by the British for his participation. His death served as a rallying call for Republicans in Mayo and led to Mayo men such as P. J. Ruttledge, Ernie O'Malley, Michael Kilroy and Thomas Derrig to rise up during the War of Independence. In the ensuing Civil War, many of these leading figures chose the Anti-treaty side and fought in bitter battles such as those in Ballina, which changed hands between pro and anti-treaty forces a number of times.
In the aftermath of the Civil War, there was a consolidation of many of those with anti-treaty feelings into the new political party Fianna Fáil. PJ Ruttledge and Thomas Derrig would become founding members of the party and served in Éamon de Valera's first-ever Fianna Fáil government as ministers. Mayo politicians would continue to contribute to the national political scene over the decades. In 1990 Mary Robinson, from County Mayo, became the first-ever female President of Ireland, and is widely credited with revitalising the position with importance and focus it had never possessed before. During her tenure she unveiled Ireland's National Famine Memorial which is situated in the village of Murrisk, County Mayo.
In 2011 Enda Kenny became the first politician from a Mayo constituency and the second Mayo native to serve as Taoiseach, the head of government of Ireland. Kenny went on to become the longest-serving Fine Gael Taoiseach in Irish history.
In the early historic period, what is now County Mayo consisted of a number of large kingdoms, minor lordships and tribes of obscure origins. They included:
Mayo County Council is the authority responsible for local government. As a county council, it is governed by the Local Government Act 2001. The county is divided into four municipal districts of Ballina, Castlebar, Claremorris and Westport–Belmullet, each with a population of roughly 32,000 to 34,000 people. The council is responsible for housing and community, roads and transportation, urban planning and development, amenity and culture, and environment.
County Mayo is divided into six local electoral areas (LEAs). Councillors are elected for a five-year term.
The county town is at Áras an Contae in Castlebar, the main population centre located in the centre of the county.
Since 2016, Mayo has been represented on a national political level by four TDs who represent the constituency of Mayo in Dáil Eireann. Previous to 2016 the constituency had five TDs but this was reduced based on the county's current population in line with proportional representation. The electoral divisions of Cong, Dalgan, Houndswood, Kilmaine, Neale, Shrule, in the former Rural District of Ballinrobe, are in Galway West.
Historically, Mayo has tended to vote Fianna Fáil, as Fianna Fáil managed to position themselves in the 20th century as the party best fit to represent farmers with small holdings, who were plentiful in Mayo. With so many of Mayo's electorate being small farmers, the county became a base for the emergence of Clann na Talmhan, an agrarian party in the 1940s and 1950s. Clann an Talmhan's second leader, Joseph Blowick came from South Mayo and that is where his seat was. The party was not able to last in the long run though as it was unable to hold together its voting bloc of both small farmers in the west of Ireland and large farmers in the east.
Towards the start of the 21st century, the balance of power in Mayo began to shift towards Fine Gael, thanks in part to the emergence of Enda Kenny and Michael Ring. Kenny, who became Taoiseach in 2011, led Fine Gael to a historic victory in the 2011 Irish general election which included securing four out of five available seats for his party in Mayo.
In 2020, Rose Conway-Walsh came within 200 votes of topping the poll and became the first Sinn Féin TD for Mayo since 1927, riding a nationwide surge for Sinn Féin that year.
Despite being historically the third-largest party in Ireland, Labour has struggled to ever make inroads into Mayo. The party has only ever had one TD for Mayo, former party leader Thomas J. O'Connell, who represented South Mayo between 1927 and 1932. While Labour has not proven itself electorally successful in Mayo, Mayo has provided important members to the Labour Party. Mary Robinson from Ballina became the first-ever female President of Ireland as a Labour candidate while Pat Rabbitte, originally from Claremorris, served as leader of the Labour Party from 2002 to 2007. Serving alongside Rabbitte was Emmet Stagg, one of the longest-standing Labour TDs of the modern era, himself from Hollymount not far from Claremorris.
The county has experienced perhaps the highest emigration out of Ireland. In the 1840s–1880s, waves of emigrants left the rural townlands of the county. Initially triggered by the Great Famine and then in search of work in the newly industrialising United Kingdom and the United States, the population plummeted from 388,887 in 1841 to 199,166 in 1901. It reached a low of 109,525 in 1971. Emigration slowed dramatically as the Irish economy began to expand in the 1990s and early 2000s, and the population of Mayo increased from 110,713 in 1991 to 130,638 in 2011.
In the 2006 National Census, the religious demographic breakdown for County Mayo was 114,215 Roman Catholics, 2,476 Church of Ireland, 733 Muslims, 409 other Christians, 280 Presbyterians, 250 Orthodox Christians, 204 Methodists, 853 other stated religions, 3,267 no religion and 1,152 no stated religion.
9% of the population of County Mayo live in the Gaeltacht. The Gaeltacht Irish-speaking region in County Mayo is the third-largest in Ireland with 10,886 inhabitants. Tourmakeady is the largest village in this area. All schools in the area use Irish as the language of instruction. Mayo has four gaelscoileanna in its four major towns, providing primary education to students through Irish.
Westport railway station is the terminus station on the Dublin to Westport Rail service. Railway stations are also located at Ballyhaunis, Claremorris, Castlebar, Manulla, Ballina and Foxford. All railway stations are located on the same railway line, with the exception of Ballina and Foxford which requires passengers to change at Manulla Junction. There are currently four services each way every day on the line.
There are also proposals to reopen the currently disused Western Railway Corridor connecting Limerick with Sligo.
There are a number of national primary roads in the county including the N5 road connecting Westport with Dublin, the N17 road connecting the county with Galway and Sligo and the N26 road connecting Ballina with Dublin via the N5. There are a number of national secondary roads in the county also including the N58 road, N59 road, N60 road, N83 road & N84 road. As of 2021, a new road running from northwest of Westport to east of Castlebar is under construction. The road is a dual carriageway with junctions at the N59, N84 and N60 and will open in late 2022.
Ireland West Airport Knock is an international airport located in the county. The name is derived from the nearby village of Knock. Recent years have seen the airport's passenger numbers grow to over 650,000 yearly with a number of UK and European destinations. August 2014 saw the airport have its busiest month on record with 102,774 passengers using the airport.
Newspapers in County Mayo include The Mayo News, the Connaught Telegraph, the Connacht Tribune, Western People, and Mayo Advertiser, which is Mayo's only free newspaper.
Mayo Now is a monthly entertainment and culture magazine for the towns of Ballina, Foxford, Killala, Crossmolina and surrounding areas – this is out on the first Friday of each month.
Mayo has its own online TV channel Mayo TV which was launched in 2011. It covers news and events from around the county and regularly broadcasts live to a worldwide audience. Local radio stations include Erris FM, Community Radio Castlebar, Westport Community Radio, BCR FM (Ballina Community Radio) and M.W.R. (Mid West Radio).
The documentary Pipe Down, which won best feature documentary at the 2009 Waterford Film Festival, was made in Mayo.
There is local resistance to Shell's decision to process raw gas from the Corrib gas field at an onshore terminal. In 2005, five local men were jailed for contempt of court after refusing to follow an Irish court order. Subsequent protests against the project led to the Shell to Sea and related campaigns.
The Mayo Energy Audit 2009–2020 is an investigation into the implications of peak oil and subsequent fossil fuel depletion for a rural county in west of Ireland. The study draws together many different strands to examine current energy supply and demand within the area of study, and assesses these demands in the face of the challenges posed by the declining production of fossil fuels and expected disruptions to supply chains, and by long-term economic recession.
The Mayo GAA senior team last won the Sam Maguire Cup in 1951, when the team was captained by Seán Flanagan. The team's third title followed victories in 1936 and the previous year, 1950. Since 1951, the team have made numerous All-Ireland Final appearances (in 1989, twice in 1996, 1997, 2004, 2006, 2012, 2013, twice again in 2016 against Dublin, 2017, 2020, with their latest appearance being against Tyrone in the 2021 final), though the team have failed on all occasions to achieve victory over their opponents.
The team's unofficial supporters club are Mayo Club '51, named after the last team who won the Sam Maguire. The county colours of Mayo GAA are traditionally green and red.
The county's most popular association football teams are Westport United and Castlebar Celtic.
Although Gaelic football and association football are the most popular sport in the county, other sports are popular in the county as well such as rugby, basketball, hurling, swimming, tennis, badminton, athletics, handball and racquetball.

It is one of three counties which claims to have the longest coastline in Ireland, alongside Cork and Donegal. There is a distinct geological difference between the west and the east of the county. The west consists largely of poor subsoils and is covered with large areas of extensive Atlantic blanket bog, whereas the east is largely a limestone landscape.

Once cliffs erode, midden remains become exposed as blackened areas containing charred stones, bones, and shells. They are usually found a metre below the surface. Mesolithic people did not have major rituals associated with burial, unlike those of the Neolithic (New Stone Age) period. The Neolithic period followed the Mesolithic around 6,000 years ago. People began to farm the land, domesticate animals for food and milk, and settle in one place for longer periods. These people had skills such as making pottery, building houses from wood, weaving, and knapping (stone tool working). The first farmers cleared forestry to graze livestock and grow crops.

Towards the end of this period, the Roman Empire was at its height in Britain but it is not thought that the Roman Empire extended into Ireland. Remains from this period, which lasted until the Early Christian period began about AD 325 (with the arrival of Saint Patrick into Ireland, as a slave) include crannógs (Lake dwellings), promontory forts, ringforts and souterrains of which there are numerous examples across the county. The Iron Age was a time of tribal warfare and kingships, each fighting neighbouring kings, vying for control of territories and taking slaves. Territories were marked by tall stone markers, Ogham stones, using the first written down words using the Ogham alphabet. The Iron Age is the time period in which the mythological tales of the Ulster Cycle and sagas took place, as well as that of the Táin Bó Flidhais, whose narrative is set in mainly in Erris.",

Many Irish people such as Grace O'Malley, the famous pirate queen, had close relationships with the English monarchy, and the English kings and queens were welcome visitors to Irish shores. The Irish however, generally held onto their Catholic religious practices and beliefs. The early plantations of settlers in Ireland began during the reign of Queen Mary in the mid-16th century and continued throughout the long reign of Queen Elizabeth I until 1603.

They marched across the county towards the administrative centre of Castlebar, leading to the Battle of Castlebar. Taking the garrison by surprise Humbert's army was victorious.

The organisation became known as the Irish National Land League, and its struggle to win rights for poor farmers in Ireland was known as the Land War.",

Charles Boycott was an English landlord deeply unpopular with his tenants. When Charles Steward Parnell made a speech in Ennis, County Clare, urging nonviolent resistance against landlords, his tactics were enthusiastically taken in Mayo against Boycott. The entire Catholic community around Lough Mask in South Mayo where Boycott had his estate became a campaign of total social ostracisation against Boycott, a tactic that would one day come to bear his name. The campaign against Boycott became a cause célèbre in the British press after he wrote a letter to The Times. The British elite rallied to his cause and Fifty Orangemen from County Cavan and County Monaghan travelled to his estate to harvest the crops, while a regiment of the 19th Royal Hussars and more than 1,000 men of the Royal Irish Constabulary were deployed to protect the harvesters. However, the cost of doing this was completely uneconomic: It cost the British government somewhere in the region of £10,000 to simply harvest £500 worth of crops. Boycott sold off the estate and the British government's resolve to try to break boycotts in this completely dissolved, resulting in victory for the tenants.",

His death served as a rallying call for Republicans in Mayo and led to Mayo men such as P. J. Ruttledge, Ernie O'Malley, Michael Kilroy and Thomas Derrig to rise up during the War of Independence.

5,833 | County Fermanagh | County Fermanagh (/fərˈmænə/ fər-MAN-ə; from Irish: Fir Manach / Fear Manach, meaning 'men of Manach') is one of the thirty-two counties of Ireland, one of the nine counties of Ulster and one of six counties of Northern Ireland
The county covers an area of 1,691 km (653 sq mi) and had a population of 63,585 as of 2021. Enniskillen is the county town and largest in both size and population.
Fermanagh is one of four counties of Northern Ireland to have a majority of its population from a Catholic background, according to the 2011 census.
Fermanagh spans an area of 1,851 km (715 sq; mi), accounting for 13.2% of the landmass of Northern Ireland. Nearly a third of the county is covered by lakes and waterways, including Upper and Lower Lough Erne and the River Erne. Forests cover 14% of the landmass (42,000 hectares). It is the only county in Northern Ireland that does not border Lough Neagh.
The county has three prominent upland areas:
The county borders:
Fermanagh is by far the least populous of Northern Ireland's six counties, with just over one-third the population of Armagh, the next least populous county.
It is approximately 120 km (75 mi) from Belfast and 160 km (99 mi) from Dublin. The county town, Enniskillen, is the largest settlement in Fermanagh, situated in the middle of the county.
The county enjoys a temperate oceanic climate (Cfb') with cool winters, mild humid summers, and a lack of temperature extremes, according to the Köppen climate classification.
The National Trust for Places of Historic Interest or Natural Beauty manages three sites of historic and natural beauty in the county: Crom Estate, Florence Court, and Castle Coole.
The oldest sediments in the county are found north of Lough Erne. These so-called red beds were formed approximately 550 million years ago. Extensive sandstone can be found in the eastern part of the county, laid down during the Devonian, 400 million years ago. Much of the rest of the county's sediments are shale and limestone dating from the Carboniferous, 354 to 298 million years ago. These softer sediments have produced extensive cave systems such as the Shannon Cave, the Marble Arch Caves and the Caves of the Tullybrack and Belmore hills. The carboniferous shale exists in several counties of northwest Ireland, an area known colloquially as the Lough Allen basin. The basin is estimated to contain 9.4 trillion cubic metres of natural gas, equivalent to 1.5 billion barrels of oil.
The county is situated over a sequence of prominent faults, primarily the Killadeas – Seskinore Fault, the Tempo – Sixmilecross Fault, the Belcoo Fault and the Clogher Valley Fault which cross-cuts Lough Erne.
The Menapii are the only known Celtic tribe specifically named on Ptolemy's 150 AD map of Ireland, where they located their first colony—Menapia—on the Leinster coast c. 216 BC. They later settled around Lough Erne, becoming known as the Fir Manach, and giving their name to Fermanagh and Monaghan. Mongán mac Fiachnai, a 7th-century King of Ulster, is the protagonist of several legends linking him with Manannán mac Lir. They spread across Ireland, evolving into historic Irish (also Scottish and Manx) clans.
The Annals of Ulster which cover medieval Ireland between AD 431 to AD 1540 were written at Belle Isle on Lough Erne near Lisbellaw.
Fermanagh was a stronghold of the Maguire clan and Donn Carrach Maguire (died 1302) was the first of the chiefs of the Maguire dynasty. However, on the confiscation of lands relating to Hugh Maguire, Fermanagh was divided in a similar manner to the other five escheated counties among Scottish and English undertakers and native Irish. The baronies of Knockninny and Magheraboy were allotted to Scottish undertakers, those of Clankelly, Magherastephana and Lurg to English undertakers and those of Clanawley, Coole, and Tyrkennedy, to servitors and natives. The chief families to benefit under the new settlement were the families of Cole, Blennerhasset, Butler, Hume, and Dunbar.
Fermanagh was made into a county by a statute of Elizabeth I, but it was not until the time of the Plantation of Ulster that it was finally brought under civil government.
The closure of all the lines of Great Northern Railway (Ireland) within County Fermanagh in 1957 left the county as the first non-island county in the UK without a railway service.
The county was administered by Fermanagh County Council from 1899 until the abolition of county councils in Northern Ireland in 1973. With the creation of Northern Ireland's district councils, Fermanagh District Council became the only one of the 26 that contained all of the county from which it derived its name. After the re-organisation of local government in 2015, Fermanagh was still the only county wholly within one council area, namely Fermanagh and Omagh District Council, albeit that it constituted only a part of that entity.
For the purposes of elections to the UK Parliament, the territory of Fermanagh is part of the Fermanagh and South Tyrone Parliamentary Constituency. This constituency elected Provisional IRA hunger-striker Bobby Sands as a member of parliament in the April 1981 Fermanagh and South Tyrone by-election, shortly before his death.
On Census Day 27 March 2011, the usually resident population of Fermanagh Local Government District, the borders of the district were very similar to those of the traditional County Fermanagh, was 61,805. Of these:
On Census Day (2021), the usually resident population of Fermanagh Local Government District, the borders of the district were very similar to those of the traditional County Fermanagh, was 63,585. Of these:
Agriculture and tourism are two of the most important industries in Fermanagh. The main types of farming in the area are beef, dairy, sheep, pigs and some poultry. Most of the agricultural land is used as grassland for grazing and silage or hay rather than for other crops.
The waterways are extensively used by cabin cruisers, other small pleasure craft and anglers. The main town of Fermanagh is Enniskillen (Inis Ceithleann, 'Ceithleann's island'). The island town hosts a range of attractions including the Castle Coole Estate and Enniskillen Castle, which is home to the museum of The Royal Inniskilling Fusiliers and the 5th Royal Inniskilling Dragoon Guards. Fermanagh is also home to The Boatyard Distillery, a distillery producing gin.
Attractions outside Enniskillen include:

The railway lines in County Fermanagh connected Enniskillen railway station with Derry from 1854, Dundalk from 1861, Bundoran from 1868 and Sligo from 1882.
The railway companies that served the county, prior to the establishment by the merger of Londonderry and Enniskillen Railway, Enniskillen and Bundoran Railway the Dundalk and Enniskillen Railway which was later named the Irish North Western Railway, thus forming the Great Northern Railway (Ireland). By 1883 the Great Northern Railway (Ireland) absorbed all the lines except the Sligo, Leitrim and Northern Counties Railway, which remained independent throughout its existence.
In October 1957 the Government of Northern Ireland closed the GNR line, which made it impossible for the SL&NCR continue and forced it also to close.
The nearest railway station to Enniskillen is Sligo station which is served by trains to Dublin Connolly and is operated by Iarnród Éireann. The Dublin-Sligo railway line has a two-hourly service run by Iarnród Éireann. The connecting bus from Sligo via Manorhamilton to Enniskillen is route 66 operated by Bus Éireann. | [

The baronies of Knockninny and Magheraboy were allotted to Scottish undertakers, those of Clankelly, Magherastephana and Lurg to English undertakers and those of Clanawley, Coole, and Tyrkennedy, to servitors and natives.

5,836 | Geography of Colombia | The Republic of Colombia is situated largely in the north-west of South America, with some territories falling within the boundaries of Central America. It is bordered to the north-west by Panama; to the east by Brazil and Venezuela; to the south by Ecuador and Peru; and it shares maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, the Dominican Republic, and Haiti.
Colombia has a land size of 1,141,748 km (440,831 sq mi) and it is the 25th largest nation in the world and the fourth-largest country in South America (after Brazil, Argentina, and Peru). Colombia's population is not evenly distributed, and most of the people live in the mountainous western portion of the country as well as along the northern coastline; the highest number live in or near the capital city of Bogotá. The southern and eastern portions of the country are sparsely inhabited, consisting of tropical rainforest, and inland tropical plains that contain large estates or large livestock farms, oil and gas production facilities, small farming communities, and indigenous tribes with their territories. Colombia has the 35th largest Exclusive Economic Zone of 808,158 km (312,032 sq mi).
Colombia usually classifies its geography into five natural regions, from the Andes mountain range, a region shared with Ecuador, Venezuela; the Pacific Ocean coastal region, shared with Panama and Ecuador; the Caribbean Sea coastal region, shared with Venezuela and Panama; the Llanos (plains), shared with Venezuela; to the Amazon Rainforest region shared with Venezuela, Brazil, Peru and Ecuador. Colombia is the only South American country that has coastline on both the Atlantic and Pacific oceans.
The World Factbook does not differentiate between the Amazon region of Colombia (predominantly jungle) and the Orinoquia region of Colombia (predominantly plains). It suggests dividing the country into four geographic regions: the Andean highlands, consisting of the three Andean ranges and intervening valley lowlands; the Caribbean lowlands coastal region; the Pacific lowlands coastal region, separated from the Caribbean lowlands by swamps at the base of the Isthmus of Panama; and eastern Colombia, the great plain that lies to the east of the Andes Mountains.
The chief western mountain range, the Cordillera Occidental, is a moderately high range with peaks reaching up to about 15,000 ft (4,572 m) (4,670 m). The Cauca River Valley, an important agricultural region with several large cities on its borders, separates the Cordillera Occidental from the massive Cordillera Central. Several snow-clad volcanoes in the Cordillera Central have summits that rise above 17,000 ft (5,182 m). The valley of the slow-flowing and muddy Magdalena River, a major transportation artery, separates the Cordillera Central from the main eastern range, the Cordillera Oriental. The peaks of the Cordillera Oriental are moderately high. This range differs from Colombia's other mountain ranges in that it contains several large basins. In the east, the sparsely populated, flat to gently rolling eastern lowlands called llanos cover almost 60 percent of the country's total land area.
This cross section of the republic does not include two of Colombia's regions: the Caribbean coastal lowlands and the Sierra Nevada de Santa Marta, both in the northern part of the country. The lowlands in the west are mostly swampy; the reed-filled marshes of the area are called ciénagas by the people of Colombia. The Guajira Peninsula in the east is semiarid and is occupied primarily by indigenous peoples. The Sierra Nevada de Santa Marta is a spectacular triangular snowcapped block of rock that towers over the eastern part of this lowland. Here can be found the highest peak of the country, named Pico Cristobal Colon (5775 m).
Near the Ecuadorian frontier, the Andes Mountains divide into three distinct, roughly parallel chains, called cordilleras, that extend northeastward almost to the Caribbean Sea. Altitudes reach more than 18,700 ft (5,700 m), and mountain peaks are permanently covered with snow. The elevated basins and plateaus of these ranges have a moderate climate that provides pleasant living conditions and in many places enables farmers to harvest twice a year. Torrential rivers on the slopes of the mountains produce a large hydroelectric power potential and add their volume to the navigable rivers in the valleys. In the late 1980s, approximately 78 percent of the country's population lived in the Andean highlands.
The Cordillera Occidental in the west, the Cordillera Central in the center, and the Cordillera Oriental in the east have different characteristics. Geologically, the Cordillera Occidental and the Cordillera Central form the western and eastern sides of a massive crystalline arch that extends from the Caribbean lowlands to the southern border of Ecuador. The Cordillera Oriental, however, is composed of folded stratified rocks overlying a crystalline core.
The Cordillera Occidental is relatively low and is the least populated of the three cordilleras. Summits are only about 9,840 ft (2,999 m) above sea level and do not have permanent snows. Few passes exist, although one that is about 4,985 ft (1,519 m) above sea level provides the major city of Cali with an outlet to the Pacific Ocean. The relatively low elevation of the cordillera permits dense vegetation, which on the western slopes is truly tropical.
The Cordillera Occidental is separated from the Cordillera Central by the deep rift of the Cauca Valley. The Río Cauca rises within 124 mi (200 km) of the border with Ecuador and flows through some of the best farmland in the country. After the two cordilleras converge, the Cauca Valley becomes a deep gorge reaching to the Caribbean lowlands.
The Cordillera Central is the loftiest of the mountain systems. Its crystalline rocks form a towering wall dotted with snow-covered volcanoes that is 500 mi (805 km) long. There are no plateaus in this range and no passes under 10,825 ft (3,299 m). The highest peak in this range, the Nevado del Huila, reaches 17,602 ft (5,365 m) above sea level. The second highest peak is a volcano, Nevado del Ruiz, which erupted violently on November 13, 1985. Toward its northern end, this cordillera separates into several branches that descend toward the Caribbean coast.
Between the Cordillera Central and the Cordillera Oriental flows the Magdalena River. This 1,600-kilometre-long (994 mi) river rises near a point some 180 km (112 mi) north of the border with Ecuador, where the Cordillera Oriental and the Cordillera Central diverge. Its spacious drainage area is fed by numerous mountain torrents originating high in the snowfields. The Magdalena River is generally navigable from the Caribbean Sea as far as the town of Neiva, deep in the interior, but it is interrupted midway by rapids. The valley floor is very deep; nearly 800 km (497 mi) from the river's mouth the elevation is no more than about 300 meters (984 ft).
In the Cordillera Oriental, at elevations between 2,500 and 2,700 meters (8,202 and 8,858 ft), three large fertile basins and a number of small ones provide suitable areas for settlement and intensive economic production. In the basin of Cundinamarca, where the Spanish encountered the regional Chibcha Indians, the European invaders established the town of Santa Fe de Bogotá (present-day Bogotá) at an elevation of 2,650 meters (8,694 ft) above sea level.
To the north of Bogotá, in the densely populated basins of Chiquinquirá and Boyacá, are fertile fields, rich mines, and large industrial establishments that produce much of the national wealth. Still farther north, where the Cordillera Oriental makes an abrupt turn to the northwest near the border with Venezuela, the Sierra Nevada de Cocuy, the highest point of this range, rises to 5,493 meters (18,022 ft) above sea level. In the department of Santander, the valleys on the western slopes are more spacious, and agriculture is intensive in the area around Bucaramanga. The northernmost region of the range around Cúcuta is so rugged that historically it has been easier for residents here to maintain communications and transportation with Venezuela than with the adjacent parts of Colombia.
The basic plantation of Colombia is grassy and is near the equator which allows many tropical-like plants.
The Caribbean lowlands consist of all of Colombia north of an imaginary line extending northeastward from the Golfo de Urabá to the Venezuelan frontier at the northern extremity of the Cordillera Oriental. The semiarid Guajira Peninsula and Guajira–Barranquilla xeric scrub, in the extreme north, bear little resemblance to the rest of the region. In the southern part rises the Sierra Nevada de Santa Marta, an isolated mountain system with peaks reaching heights over 5,700 meters (18,701 ft) and slopes generally too steep for cultivation.
The Caribbean lowlands region is in roughly the shape of a triangle, the longest side of which is the coastline. Most of the country's commerce moves through the cities of Cartagena, Barranquilla, Santa Marta, and the other ports located along this important coast. Inland from these cities are swamps, hidden streams, and shallow lakes that support banana and cotton plantations for major commodity crops, countless small farms, and, in higher places, cattle ranches.
The city of Cartagena is a petrochemical, seaport (#1 in the country), and tourist city (#1 in the country). Santa Marta is also a seaport and tourist city but it is smaller scale city in comparison. Barranquilla is located some 25 miles (40 km) from the Caribbean coastline but it is a more developed city, with a greater number of industries and commercial places, widely known for its skilled workers in producing all forms of metalwork and accomplishing construction. Its inhabitants have the highest education level of the region. The city is famous as the starting point and focus of the region and the country's development: it was the first city in the nation to install and use telephones, public lighting, air mail, planes, and industrial works.
The Caribbean region merges next to and is connected with the Andean highlands through the two great river valleys. After the Andean highlands, it is the second-most important region in terms of economic activity. Approximately 17% of the country's population lived in this region in the late 1980s.
The region also includes the peninsular archipelago of San Andres Island and the Insular Territories of Colombia, which are disputed in part by Nicaragua. However, the Colombian Navy protects such territories with the use of force when necessary to avoid foreign invasion. The islands are fortified with two important bases for defense and custom controls. These were formerly used for research of classified projects with civilian assistance; the local universities often conduct research in the areas of oceanography and marine biology but also in the fields of biochemistry, genetics and immunology. Colombia is known for its advances in medical fields in experimental surgery, breast implant development, or prosthetics, and immunology. These facilities serve as containment and secure experimentation labs to complement those in Barranquilla and other undisclosed locations within the coast territories.
The Insular Region is considered by some as a geopolitical region of Colombia. It comprises the areas outside the continental territories of Colombia and includes the San Andrés y Providencia Department in the Caribbean sea and the Malpelo and Gorgona islands in the Pacific Ocean. Its subregions include other groups of islands:
The western third of the country is the most geographically complex. Starting at the shore of the Pacific Ocean in the west and moving eastward at a latitude of 5 degrees north, a diverse sequence of features is encountered. In the extreme west are the very narrow and discontinuous Pacific coastal lowlands, which are backed by the Serranía de Baudó, the lowest and narrowest of Colombia's mountain ranges. Next is the broad region of the Río Atrato/Río San Juan lowland.
In 1855, William Kennish, an engineer and veteran of the British Royal Navy, who had immigrated to the United States and was working for a New York City firm, studied the area and proposed an inter-oceanic river aqueduct and tunnel to connect the Rio Atrato, with its mouth at the Atlantic Ocean, with tributaries and through a tunnel and aqueduct through Nerqua Pass, to flow into Bahía Humboldt at the Pacific Ocean.
This was his alternative to the canal that was eventually built further west on the isthmus of what became Panama after it gained independence in the early 20th century. Although the US sent an expedition to explore Kennish's proposal, the concept was not developed at the time. Colombia refused a later US offer to build a canal. After independence, in 1903 Panama made a treaty with the US to support construction of the Panama Canal. Colombia occupies most of the Andes mountain range northern extremity, sharing a bit with Venezuela; the range splits into three branches between the Colombia-Ecuador border.
In the 1980s, only three percent of all Colombians resided in the Pacific lowlands, a region of jungle and swamp with considerable but little-exploited potential in minerals and other resources. Later in the 20th century, it was threatened by mining-related deforestation, as gold mining proceeded by both major companies and artisan miners. Buenaventura is the only port of any size on the coast. To the east, the Pacific lowlands are bounded by the Cordillera Occidental, from which numerous streams run. Most of the streams flow westward to the Pacific, but the largest, the navigable Río Atrato, flows northward to the Golfo de Urabá. Its river settlements have access to the major Atlantic ports and consequently are commercially related primarily to the Caribbean lowlands hinterland. To the west of the Río Atrato rises the Serranía de Baudó, an isolated chain of low mountains that occupies a large part of the region. Its highest elevation is less than 1,800 meters, and its vegetation resembles that of the surrounding tropical forest.
The Atrato Swamp, in Chocó Department adjoining the border with Panama, is a deep muck sixty-five kilometers in width. For years it has challenged engineers seeking to complete the Pan-American Highway. This stretch, near Turbo, where the highway is interrupted, is known as the Tapón del Chocó (Chocon Plug).
A second major transportation project in Chocó Department has been proposed. A second inter-oceanic canal would be constructed by dredging the Río Atrato and tributary streams and digging short access canals. Completion of either of these projects would do much to transform this region, although it could have devastating consequences on the fragile, tropical forest environment.
The area east of the Andes includes about 699,300 square kilometers or three-fifths of the country's total area, but Colombians view it almost as an alien land. The entire area, known as the eastern plains, was home to only two percent of the country's population in the late 1980s. The Spanish term for plains (llanos) can be applied only to the open plains in the northern part, particularly the Piedmont areas near the Cordillera Oriental, where extensive cattle raising is practiced.
The region is unbroken by highlands except in Meta Department, where the Serranía de la Macarena, an outlier of the Andes has unique vegetation and wildlife believed to be reminiscent of those that once existed throughout the Andes.
Many of the numerous large rivers of eastern Colombia are navigable. The Río Guaviare and the streams to its north flow eastward and drain into the basin of the Río Orinoco, a river that crosses into Venezuela and flows into the Atlantic Ocean. Those south of the Río Guaviare flows into the Amazon Basin. The Río Guaviare divides eastern Colombia into the llanos subregion in the north and the tropical rainforest, or selva, subregion in the south.
The striking variety in temperature and precipitation results principally from differences in elevation. Temperatures range from very hot at sea level to relatively cold at higher elevations but vary little with the season. At Bogotá, for example, the average annual temperature is 15 °C (59 °F), and the difference between the average of the coldest and the warmest months is less than 1 °C (1.8 °F). More significant, however, is the daily variation in temperature, from 5 °C (41 °F) at night to 17 °C (62.6 °F) during the day.
Colombians customarily describe their country in terms of the climatic zones: the area under 900 meters (2,953 ft) in elevation is called the hot zone (tierra caliente), elevations between 900 and 1,980 meters (2,953 and 6,496 ft) are the temperate zone (tierra templada), and elevations from 1,980 meters (6,496 ft) to about 3,500 meters (11,483 ft) constitute the cold zone (tierra fría). The upper limit of the cold zone marks the tree line and the approximate limit of human habitation. The treeless regions adjacent to the cold zone and extending to approximately 4,500 meters (14,764 ft) are high, bleak areas (usually referred to as the páramos), above which begins the area of permanent snow (nevado).
About 86% of the country's total area lies in the hot zone. Included in the hot zone and interrupting the temperate area of the Andean highlands are the long and narrow extension of the Magdalena Valley and a small extension in the Cauca Valley. Temperatures, depending on elevation, vary between 24 and 38 °C (75.2 and 100.4 °F), and there are alternating dry and wet seasons corresponding to summer and winter, respectively. Breezes on the Caribbean coast, however, reduce both heat and precipitation.
Rainfall in the hot zone is heaviest in the Pacific lowlands and in parts of eastern Colombia, where rain is almost a daily occurrence and rain forests predominate. Precipitation exceeds 7,600 millimeters (299.2 in) annually in most of the Pacific lowlands, making this one of the wettest regions in the world. The highest average annual precipitation in the world is estimated to be in Lloro, Colombia, with 13,299 mm (523.6 in). In eastern Colombia, it decreases from 6,350 millimeters (250 in) in portions of the Andean Piedmont to 2,540 millimeters (100 in) eastward. Extensive areas of the Caribbean interior are permanently flooded, more because of poor drainage than because of the moderately heavy precipitation during the rainy season from May through October.
The temperate zone covers about 8% of the country. This zone includes the lower slopes of the Cordillera Oriental and the Cordillera Central and most of the intermontane valleys. The important cities of Medellín (1,487 meters or 4,879 feet) and Cali (1,030 meters or 3,379 feet) are located in this zone, where rainfall is moderate and the mean annual temperature varies between 19 and 24 °C (66.2 and 75.2 °F), depending on the elevation. In the higher elevations of this zone, farmers benefit from two wet and two dry seasons each year; January through March and July through September are the dry seasons.
The cold or cool zone constitutes about 6% of the total area, including some of the most densely populated plateaus and terraces of the Colombian Andes; this zone supports about one fourth of the country's total population. The mean temperature ranges between 10 and 19 °C (50.0 and 66.2 °F), and the wet seasons occur in April and May and from September to December, as in the high elevations of the temperate zone.
Precipitation is moderate to heavy in most parts of the country; the heavier rainfall occurs in the low-lying hot zone. Considerable variations occur because of local conditions that affect wind currents, however, and areas on the leeward side of the Guajira Peninsula receive generally light rainfall; the annual rainfall of 350 millimeters (13.8 in) recorded at the Uribia station there is the lowest in Colombia. Considerable year-to-year variations have been recorded, and Colombia sometimes experiences droughts.
Colombia's geographic and climatic variations have combined to produce relatively well-defined "ethnocultural" groups among different regions of the country: the Costeño from the Caribbean coast; the Caucano in the Cauca region and the Pacific coast; the Antioqueño in Antioquia, Caldas, Risaralda, and Valle del Cauca departments; the Tolimense in Tolima and Huila departments; the Cundiboyacense in the interior departments of Cundinamarca and Boyacá in the Cordillera Oriental; the Santandereano in Norte de Santander and Santander departments; and the Llanero in the eastern plains. Each group has distinctive characteristics, accents, customs, social patterns, and forms of cultural adaptation to climate and topography that differentiates it from other groups. Even with rapid urbanization and modernization, regionalism and regional identification continued to be important reference points, although they were somewhat less prominent in the 1980s than in the nineteenth and early twentieth centuries.
Colombia's proximity to the equator influences its climates. The lowland areas are continuously hot. Altitude affects temperature greatly. Temperatures decrease about 3.5 °F (1.9 °C) for every 1,000-foot (305 m) increase in altitude above sea level. Rainfall varies by location in Colombia, tending to increase as one travels southward. This is especially true in the eastern lowlands. For example, rainfall in parts of the Guajira Peninsula seldom exceeds 30 in (762 mm) per year. Colombia's rainy southeast, however, is often drenched by more than 200 in (5,080 mm) of rain per year. Rainfall in most of the rest of the country runs between these two extremes.
Altitude affects not only temperature, but also vegetation. In fact, altitude is one of the most important influences on vegetation patterns in Colombia. The mountainous parts of the country can be divided into several vegetation zones according to altitude, although the altitude limits of each zone may vary somewhat depending on the latitude.
The "tierra caliente" (hot land), below 1,000 m (3,300 ft), is the zone of tropical crops such as bananas. The tierra templada (temperate land), extending from an altitude of 1,000 to 2,000 m (3,300 to 6,600 ft), is the zone of coffee and maize. Wheat and potatoes dominate in the "tierra fría" (cold land), at altitudes from 2,000 to 3,200 m (6,600 to 10,500 ft). In the "zona forestada" (forested zone), which is located between 3,200 and 4,000 m (10,500 and 13,100 ft), many of the trees have been cut for firewood. Treeless pastures dominate the páramos, or alpine grasslands, at altitudes of 4,000 to 4,500 m (13,100 to 14,800 ft). Above 4,500 m (14,800 ft), where temperatures are below freezing, is the "tierra helada", a zone of permanent snow and ice.
Vegetation also responds to rainfall patterns. A scrub woodland of scattered trees and bushes dominates the semiarid northeast. To the south, savannah (tropical grassland) vegetation covers the Colombian portion of the llanos. The rainy areas in the southeast are blanketed by tropical rainforest. In the mountains, the spotty patterns of precipitation in alpine areas complicate vegetation patterns. The rainy side of a mountain may be lush and green, while the other side, in the rain shadow, may be parched.
The Andean range is located in Colombia from the southwest (Ecuador border) toward the northeast (Venezuela border) and is divided in the Colombian Massif (Macizo Colombiano) in three ranges (East Andes, Central Andes and West Andes) that form two long valleys, Magdalena and Cauca follow by the rivers of the same name.
The eastern half of Colombia, comprising more than half its territory, is plain and composed by savanna and rainforest, crossed by rivers belonging to the Amazon and Orinoco basins. The northern part, called the Llanos, is a savanna region, mostly in the Orinoco basin (therefore called also Orinoquía). The southern part is covered by the Amazon rain forest and belongs mostly to the Amazon basin. It is usually called Amazonía.
At the north and west of the Andes range there are some coastal plains. The Caribbean plains at the north and the Pacific plains at the west.
A recent global remote sensing analysis suggested that there were 553km² of tidal flats in Colombia, making it the 46th ranked country in terms of tidal flat area.
Colombian Pacific Plains are among the most rainy parts in the world, chiefly at the north (Chocó).
The highest mountain in Colombia is not in the Andes but in the Caribbean plain: Sierra Nevada de Santa Marta with its highest points named Pico Cristobal Colon (5775 m) and Pico Simon Bolivar (same elevation). Other mountains in the Caribbean plain include the Montes de María and the Serranía de San Lucas.
In the Pacific Plains there are other mountain formations, chiefly the Serranía del Darién and the Serranía del Baudó.
In the eastern Region, there is the Serranía de la Macarena and there are formations belonging to the Guyana Shield.
The natural resources of Colombia are varied and extensive with most of its territory and oceans still unexplored. Colombia has one of the largest open pit coal mines in the world in the region of Cerrejon in the Guajira Peninsula. It also has oil rigs and natural gas extraction in the eastern plains. Colombia is the main producer of emeralds and an important participant in gold, silver, iron, salt, platinum, petroleum, nickel, copper, hydropower and uranium extraction.
The main environmental issues affecting Colombia are deforestation; soil and water quality damage from overuse of pesticides; air pollution, especially in Bogota, from vehicle emissions and other main cities. The collateral damaged produced by attacks against oil pipeline infrastructure by rebel guerrillas in the Colombian armed conflict has produced long term damage to the environment. The armed groups also deforest large areas to cultivate illegal crops and open unauthorized highways in protected areas.
Snowfields and glaciers in Colombia are limited to the highest peaks and ranges in the Cordillera Central and Cordillera Oriental and above the 4,700-metre (15,400 ft) elevation on the Sierra Nevada de Santa Marta. The total area of snowfields and glaciers was estimated to be about 104 square kilometers in the early 1970s.
Historical, geographical, and pictorial records point toward a consistent and progressive depletion of ice-and-snow masses in the Colombian Andes since the end of the "Little Ice Age" in the late 1800s. Many glaciers have disappeared during the 20th century, and others are expected to disappear in the coming decades.

] | The Republic of Colombia is situated largely in the north-west of South America, with some territories falling within the boundaries of Central America. It is bordered to the north-west by Panama; to the east by Brazil and Venezuela; to the south by Ecuador and Peru; and it shares maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, the Dominican Republic, and Haiti. Colombia has a land size of 1,141,748 km2 (440,831 sq mi) and it is the 25th largest nation in the world and the fourth-largest country in South America. Colombia's population is not evenly distributed, and most of the people live in the mountainous western portion of the country as well as along the northern coastline; the highest number live in or near the capital city of Bogotá. The southern and eastern portions of the country are sparsely inhabited, consisting of tropical rainforest, and inland tropical plains that contain large estates or large livestock farms, oil and gas production facilities, small farming communities, and indigenous tribes with their territories. Colombia has the 35th largest Exclusive Economic Zone of 808,158 km2 (312,032 sq mi). | 2001-07-20T18:47:57Z | 2023-12-19T21:58:26Z | [

5,838 | Politics of Colombia | The politics of Colombia take place in a framework of a presidential representative democratic republic, whereby the President of Colombia is both head of state and head of government, and of a multi-party system. Executive power is carried out by the government. Legislative power is vested in both the government and the two chambers of congress, the Senate and the House of Representatives of Colombia. The Judiciary is independent of the executive and the legislature.
The Economist Intelligence Unit rated Colombia a "flawed democracy" in 2022.
Colombia's present constitution, enacted on July 5, 1991, strengthened the administration of justice with the provision for introduction of an adversarial system which ultimately is to entirely replace the existing Napoleonic Code. Other significant reforms under the new constitution provide for civil divorce, dual nationality, the election of a vice president, and the election of departmental governors. The constitution expanded citizens' basic rights, including that of "tutela," under which an immediate court action can be requested by individuals feeling that their constitutional rights are being violated and if there is no other legal recourse.
The national government has separate executive, legislative, and judicial branches.
The president is elected for a single four-year term. Between 2005 and 2015, the president could be re-elected for a second term. The 1991 constitution reestablished the position of vice president, who is elected on the same ticket as the president. By law, the vice president will succeed in the event of the president's resignation, illness, or death.
Since 2015, the president is barred from running for reelection, even for a nonconsecutive term.
Colombia's bicameral Congress consists of a 108-member Senate of Colombia and a 172-member Chamber of Representatives of Colombia. Senators are elected on the basis of a nationwide ballot, while representatives are elected in multi member districts co-located within the 32 national departments. The country's capital is a separate capital district and elects its own representatives. Members may be re-elected indefinitely, and, in contrast to the previous system, there are no alternate congressmen. Congress meets twice a year, and the president has the power to call it into special session when needed.
Duque won the nomination, and following his victory, he selected the runner-up, Ramírez, to be the alliance's vice presidential nominee.

5,839 | Economy of Colombia | The economy of Colombia is the fourth largest in Latin America as measured by gross domestic product and the third-largest economic power in South America. Colombia has experienced a historic economic boom over the last decade. Throughout most of the 20th century, Colombia was Latin America's 4th and 3rd largest economy when measured by nominal GDP, real GDP, GDP (PPP), and real GDP at chained PPPs. Between 2012 and 2014, it became the 3rd largest in Latin America by nominal GDP. As of 2018, the GDP (PPP) per capita has increased to over US$14,000, and real gross domestic product at chained PPPs increased from US$250 billion in 1990 to nearly US$800 billion. Poverty levels were as high as 65% in 1990, but decreased to under 30% by 2014, and 27% by 2018. They decreased by an average of 1.35% per year since 1990.
Petroleum is Colombia's main export, representing over 45% of Colombia's exports. Manufacturing represents nearly 12% of Colombia's exports, and grows at a rate of over 10% a year. Colombia has the fastest growing information technology industry in the world, and has the longest fibre optic network in Latin America. Colombia also has one of the largest shipbuilding industries in the world outside Asia.
Modern industries like shipbuilding, electronics, automobile, tourism, construction, and mining, grew dramatically during the 2000s and 2010s. However, most of Colombia's exports are still commodity-based. Colombia is Latin America's 2nd-largest producer of domestically made electronics and appliances, following Mexico. Colombia had the fastest-growing major economy in the Western world in 2014, behind only China worldwide.
Since the early 2010s, the Colombian government has shown interest in exporting modern Colombian pop culture to the world (which includes video games, music, films, television shows, fashion, cosmetics, and food) as a way of diversifying the economy and entirely changing the image of Colombia. This has inspired a national campaign, similar to the Korean Wave. Colombia is only behind Mexico in cultural exports, and is already a regional leader in cosmetic and beauty exports.
Wealth is poorly distributed, since with a Gini index of approximately 0.̟6, Colombia is among the most unequal societies in the world. For example, according to the World Bank, in 2010 the richest 20% of the population owned 60.2% of the wealth and the poorest 20% only 3%, and 15.8% of Colombians lived on less than $2 a day. In 2021, more than 54% of Colombian families are food insecure and more than 560,000 children under the age of five are chronically undernourished.
The informal economy is estimated at 47% in 2020. There is no welfare state in Colombia, which has almost no unemployment or pension insurance system. As a result, only one million elderly people have pensions (and five million are without) and social assistance is very low. Many people in their 70s and 80s are forced to continue working or beg. The country is said to be the most unequal in the Organisation for Economic Co-operation and Development (OECD).
European explorers reached what is now Colombian territory as early as 1510 in Santa María Antigua del Darién (in present-day Chocó department). For the next couple of decades Colombia, and South America in general, remained largely unexplored. From 1533 to 1600, Europeans began expeditions into the interior of current Colombia. The in of these expeditions was mainly to conquer new lands and exploit village resources. Legends of El Dorado that reached Spaniard explorers continued to fuel exploration and raiding of Indian villages.
In the 17th century, Spanish conquerors explored Colombia and made the first settlements, and this was the beginning of Colombia's modern economic history. Major conquistadors from this period were Pedro de Heredia, Gonzalo Jimenez de Quesada, Sebastián de Belalcazar, and Nikolaus Federmann.
During the 16th and 17th centuries, the colonial settlements in Colombia served purposes of extraction of precious metals and other natural resources, and later slavery trade. This economic arrangement left the Colony with little room for building solid institutionality for economic development. The main non-extractive institutions emerging in this centuries were the fortified port of Cartagena and the Viceroyalty of New Granada. Cartagena developed military defenses mainly out of necessity from frequently having to deal with pirate attacks. A primitive form of colonial administration was organized in Santa fé de Bogotá with the Viceroyalty of New Granada, especially under the tenure of José Solís Folch de Cardona (1753–1761), who conducted a census and built roads, bridges and aqueducts.
Following the Thousand Days' War (1899–1902), Colombia experienced a coffee boom that catapulted the country into the modern period, bringing the attendant benefits of transportation, particularly railroads, communications infrastructure, and the first major attempts at manufacturing.
Colombia's consistently sound economic policies and aggressive promotion of free trade agreements in recent years have bolstered its ability to weather external shocks. Real GDP has grown more than 4% per year for the past three years, continuing almost a decade of strong economic performance.
In 1990, the administration of President César Gaviria Trujillo (1990–94) initiated economic liberalism policies or "apertura economica" and this has continued since then, with tariff reductions, financial deregulation, privatization of state-owned enterprises, and adoption of a more liberal foreign exchange rate. Almost all sectors became open to foreign investment although agricultural products remained protected.
The original idea of his then Minister of Finance, Rudolf Homes, was that the country should import agricultural products in which it was not competitive, like maize, wheat, cotton and soybeans and export the ones in which it had an advantage, like fruits and flowers. In ten years, the sector lost 7,000 km to imports, with a critical impact on employment in rural areas. Still, this policy makes food cheaper for the average Colombian than it would be if agricultural trade were more restricted.
Until 1997, Colombia had enjoyed a fairly stable economy. The first five years of liberalization were characterized by high economic growth rates of between 4% and 5%. The Ernesto Samper administration (1994–98) emphasized social welfare policies which targeted Colombia's lower income population. These reforms led to higher government spending which increased the fiscal deficit and public sector debt, the financing of which required higher interest rates. An over-valued peso inherited from the previous administration was maintained.
The economy slowed, and by 1998 GDP growth was only 0.6%. In 1999, the country fell into its first recession since the Great Depression. The economy shrank by 4.5% with unemployment at over 20%. While unemployment remained at 20% in 2000, GDP growth recovered to 3.1%. Unemployment in 2020 has improved compared to two decades ago to 12.20%.
The administration of President Andrés Pastrana Arango, when it took office on 7 August 1998, faced an economy in crisis, with the difficult internal security situation and global economic turbulence additionally inhibiting confidence. As evidence of a serious recession became clear in 1999, the government took a number of steps. It engaged in a series of controlled devaluations of the peso, followed by a decision to let it float. Colombia also entered into an agreement with the International Monetary Fund which provided a $2.7 billion guarantee (extended funds facility), while committing the government to budget discipline and structural reforms.
By early 2000 there had been the beginning of an economic recovery, with the export sector leading the way, as it enjoyed the benefit of the more competitive exchange rate, as well as strong prices for petroleum, Colombia's leading export product. Prices of coffee, the other principal export product, have been more variable.
Economic growth reached 3.1% during 2000 and inflation 9.0%. Inflation by 2021 has stabilized at 3.30%. Colombia's international reserves remained stable at around $8.35 billion in the year 2000 growing to $58.57 billion by 2021, and Colombia has successfully remained in international capital markets. Colombia's total foreign debt at the end of 1999 was $34.5 billion with $14.7 billion in private sector and $19.8 billion in public sector debt. Major international credit rating organizations had dropped Colombian sovereign debt below investment grade, primarily as a result of large fiscal deficits, which current policies are seeking to close. As of 2021 Colombia has recovered its investment grade rating.
Former president Álvaro Uribe (elected 7 August 2002) introduced several neoliberal economic reforms, including measures designed to reduce the public-sector deficit below 2.5% of GDP in 2004. The government's economic policy and controversial democratic security strategy have engendered a growing sense of confidence in the economy, particularly within the business sector, and GDP growth in 2003 was among the highest in Latin America, at over 4%. This growth rate was maintained over the next decade, averaging 4.8% from 2004 to 2014.
According to figures from Dane, monetary poverty went from 37.2% in 2010 to 26.9% in 2017, which indicates a higher income for the most vulnerable households. During the Santos government, there was an inflationary period that was also a response to the strong external shock of the fall in oil prices. It was a period of contained instability, although inflation increased, no company declared bankruptcy and there was no instability in the financial system.
The Santos period managed an increase in GDP of 4% in 2010, which peaked in 2011 to 6.6%. Thereafter it remained at 4% in 2012, 4.9% in 2013 and 4.4% in 2014. In 2011, Colombia recovered it's BBB- investment grade, which was raised in 2013 to BBB. As a result of sustained growth, during the eight years of the Santos government, 3.5 million jobs were created, while 5.4 million people were lifted out of poverty.
The focus of Santos' second term was to reach a peace agreement with the FARC whose economic effects, according to assumptions, could imply a GDP growth of up to two additional percentage points. Santos' best legacy is precisely the one related to security since this will have an effect in the medium and long term in terms of investment decisions, job creation, and the beginning of a great revolution in the country's infrastructure: war prevented development in the most affected areas for centuries.
Colombia's President Iván Duque withdrew a controversial tax reform bill following four weeks of huge protests across the country starting 28 April 2021. In 2021, Colombia registered an increase in Gross Domestic Product of more than 10%, as a result of a rebound effect that derived from the 6.8% collapse a year earlier, caused by the economic closures decreed to stop the coronavirus pandemic. The pandemic exacerbated poverty. In 2021, official figures showed that 39% of Colombians -out of a population of 51.6 million inhabitants- were in a condition of monetary poverty. Although it shows a slight improvement compared to 2020 (42.5%), it meant a setback of at least a decade.
The greatest increase in the value of the debt also occurred in the Duque government, according to figures from the Bank of the Republic. Between 2020 and 2021 the balance increased by 17 billion dollars, and from 2019 to 2020 it increased by 16 billion. That figure, which corresponds to a deficit of 7.1 percent of GDP, was the debt that the Central National Government or GNC (the State without its companies or regional entities) had in 2021, according to the fiscal closing bulletin.
In the Duque government, specifically between May and June 2020, 66.7 percent of the country's gold reserves were sold, which went from 710.5 to 237.4 million dollars. The decision was made by the Bank of the Republic. The sale received criticism because although it was done at a time of rising prices – after five years in which this did not happen – it was before gold reached a record price.
The longstanding internal armed conflict in Colombia has had economic impacts.
In the early 21st century, the Colombian economy grew in part because of austere government budgets, focused efforts to reduce public debt levels, an export-oriented growth strategy, an improved security situation in the country, and high commodity prices. Growth slowed to 1.4 percent in 2017, and then increased to 3.3 percent in 2019.
President Uribe, who was in office from 2002 to 2010, examined opportunities including reforming the pension system, reducing high unemployment, achieving congressional passage of a fiscal transfers reform, and exploring for new oil or producing ethanol. Colombia's Gini coefficient, a measure of inequality, was one of the highest in South America. International and domestic financial analysts warned of the growing central government deficit, which hovered at 5% of GDP. Nonetheless, confidence in the economy grew.
Colombia has a track record of prudent macroeconomic management.
The middle class will represent 25% of the population in 2020 according to a survey by the daily newspaper El Tiempo. Official data indicate that 42.5% of the population lives below the poverty line. The social elevator is one of the slowest in the world, as it takes an average of eleven generations for a family to rise out of poverty.
The tax system is one of the causes of Colombia's deep social inequalities. The income tax (IRPP) is not very progressive (almost all taxpayers pay it at a rate of between 19% and 28%, and the rate rises only slightly thereafter) and is levied mainly on salaries, with other categories of income being largely underreported. Redistribution through the Colombian tax system is thus the lowest in Latin America, even though it is on average very limited.
The following table shows the main economic indicators in 1980–2019 (with IMF staff stimtates in 2020–2025). Inflation below 5% is in green.

On 8 June 2020, the newly formed Employment Mission (Misión de Empleo) met for the first time to discuss labor reforms that it intended to propose to Congress. Some of these reforms had been desired for years, and others had come into starker view during the coronavirus pandemic.
The legal working hours are 48 hours per week. However, the informal economy accounts for almost half of the workers, who are therefore not covered by labor laws.
Colombia is one of the 5 largest producers in the world of coffee, avocado and palm oil, and one of the 10 largest producers in the world of sugarcane, banana, pineapple and cocoa.
Colombia produced, in 2018, 36.2 million tons of sugarcane (7th largest producer in the world), 5.8 million tons of palm oil (5th largest producer in the world), 3.7 million tons of banana (11th largest producer in the world) and 720 thousand tons of coffee (4th largest producer in the world, behind Brazil, Vietnam and Indonesia). Although its neighbor Brazil is the largest producer of coffee in the world (3.5 million tons produced in the same year), the advertising carried out by the country for decades suggests that Colombian coffee is of higher quality, which generates greater added value to the country's product. In the same year, Colombia produced 3.3 million tons of rice, 3.1 million tons of potato, 2.2 million tons of cassava, 1.3 million tons of maize, 900 thousand tons of pineapple, 670 thousand tons of onion, 527 thousand tons of tomato, 419 thousand tons of yam, 338 thousand tons of mango, 326 thousand tons of avocado, in addition to smaller productions of other agricultural products such as orange, tangerine, lemon, papaya, beans, carrot, coconut, watermelon etc.
The share of agriculture in GDP has fallen consistently since 1945, as industry and services have expanded. However, Colombia's agricultural share of GDP decreased during the 1990s by less than in many of the world's countries at a similar level of development, even though the share of coffee in GDP diminished in a dramatic way. Agriculture has nevertheless remained an important source of employment, providing a fifth of Colombia's jobs in 2006.
The most industrially diverse member of the five-nation Andean Community, Colombia has four major industrial centers—Bogota, Medellin, Cali, and Barranquilla, each located in a distinct geographical region. Colombia's industries include textiles and clothing, particularly lingerie, leather products, processed foods and beverages, paper and paper products, chemicals and petrochemicals, cement, construction, iron and steel products, and metalworking. Its diverse climate and topography permit the cultivation of a wide variety of crops. In addition, all regions yield forest products, ranging from tropical hardwoods in the hot country to pine and eucalyptus in the colder areas.
Cacao beans, sugarcane, coconuts, bananas, plantains, rice, cotton, tobacco, cassava, and most of the nation's beef cattle are produced in the hot regions from sea level to 1,000 meters elevation. The temperate regions—between 1,000 and 2,000 meters—are better suited for coffee; cut flowers; maize and other vegetables; and fruits such as citrus, pears, pineapples, and tomatoes. The cooler elevations—between 2,000 and 3,000 meters—produce wheat, barley, potatoes, cold-climate vegetables, flowers, dairy cattle, and poultry.
In the production of beef and chicken meat, Colombia is among the 20 largest producers in the world.
In Colombia, the exploitation and breeding of cattle is carried out on small farms and large farms. Black-eared white, casanareño, coastal with horns, romosinuano, chino santandereano and hartón del Valle, are the Colombian breeds with the highest production.
In 2013, livestock occupied 80% of productive land in Colombia. The livestock sector is one of the most outstanding in areas such as Caribbean Region, where seven departments have livestock as their primary vocation. Also in Antioquia, where there is the largest cattle inventory in the country, the department had that year 11% of the head of cattle in Colombia, and according to the livestock inventory, in 2012 Antioqueños counted around 2,268,000 head of cattle.
Also in 2013, the bovine herd in Colombia reached 20.1 million head of cattle, of which 2.5 million (12.5%) were milking cows. In addition, the country's total milk production was 13.1 million liters.
On the other hand, the increase in imports of pork meat, the high prices of inputs and the slowdown in the national economy, produced a crisis in the raising of pork in Colombia in 2015.
The World Bank lists the main producing countries each year, based on the total value of production. According to the 2019 list, Colombia has the 46th most valuable industry in the world (US$35.4 billion), behind Mexico, Brazil, Venezuela and Argentina, but ahead of Peru and Chile.
Although Colombia has been producing domestic appliances since the 1930s, it wasn't until the late 1990s that Colombian corporations began exporting to neighboring countries. One of Colombia's largest producers of domestic appliances, HACEB has been producing refrigeration since 1940. Some domestic corporations include: Challenger, Kalley, HACEB, Imusa, and Landers. In 2011, Groupe SEB acquired Imusa as a form to expand to the Latin American market. Colombia also manufactures for foreign companies as well, such as Whirlpool and GE. LG has also been interested in building a plant in Colombia. Colombia is also Latin America's 3rd largest producer of appliances behind Mexico and Brazil and is growing rapidly.
Colombia is a major producer of electronics in Latin America, and is South America's 2nd largest high-tech market. Colombia is also the 2nd largest producer and exporter of electronics made by domestic companies in Latin America. Since the early 2000s, major Colombian corporations began exporting aggressively to foreign markets. Some of these companies include: Challenger, PcSmart, Compumax, Colcircuirtos, and Kalley. Colombia is the first country in Latin America to manufacture a domestically made 4K television. In 2014, the Colombian Government launched a national campaign to promote IT and Electronic sectors, as well as investing in Colombia's own companies. Although innovation remains low on the global scale, the government sees heavy potential in the high tech industry and is investing heavily in education and innovation centers all across the nation. Because of this, Colombia could become a major global manufacturer of electronics and play an important role in the global high tech industry in the near future. In 2014, the Colombian government released another national campaign to help Colombian companies have a bigger share of the national market.
Construction recently has played a vital role in the economy, and is growing rapidly at almost 20% annually. As a result, Colombia is seeing a historic building boom. The Colombian government is investing heavily in transport infrastructure through a plan called "Fourth Generation Network". The target of the Colombian government is to build 7,000 km of roads for the 2016–2020 period and reduce travel times by 30% and transport costs by 20%. A toll road concession program will comprise 40 projects, and is part of a larger strategic goal to invest nearly $50bn in transport infrastructure, including: railway systems; making the Magdalena river navigable again; improving port facilities; as well as an expansion of Bogotá's airport. Long-term plans include building a national high-speed train network, to vastly improve competitiveness.
Colombia is well-endowed with minerals and energy resources. It has the largest coal reserves in Latin America, and is second to Brazil in hydroelectric potential. Estimates of petroleum reserves in 1995 were 3.1 billion barrels (490,000,000 m). It also possesses significant amounts of nickel, gold, silver, platinum, and emeralds.
The country was the 12th largest producer of coal in the world in 2018. In 2019, Colombia was the 20th largest petroleum producer in the world, with 791 thousand barrels / day. In mining, Colombia is the world's largest producer of emerald.
The discovery of 2 billion barrels (320,000,000 m) of high-quality oil at the Cusiana and Cupiagua fields, about 200 kilometres (120 mi) east of Bogotá, has enabled Colombia to become a net oil exporter since 1986. The Transandino pipeline transports oil from Orito in the Department of Putumayo to the Pacific port of Tumaco in the Department of Nariño. Total crude oil production averages 620 thousand barrels per day (99,000 m/d); about 184 thousand barrels per day (29,300 m/d) is exported. The Pastrana government has significantly liberalized its petroleum investment policies, leading to an increase in exploration activity. Refining capacity cannot satisfy domestic demand, so some refined products, especially gasoline, must be imported. Plans for the construction of a new refinery are under development.
While Colombia has vast hydroelectric potential, a prolonged drought in 1992 forced severe electricity rationing throughout the country until mid-1993. The consequences of the drought on electricity-generating capacity caused the government to commission the construction or upgrading of 10 thermoelectric power plants. Half will be coal-fired, and half will be fired by natural gas. The government also has begun awarding bids for the construction of a natural gas pipeline system that will extend from the country's extensive gas fields to its major population centers. Plans call for this project to make natural gas available to millions of Colombian households by the middle of the next decade.
As of 2004, Colombia has become a net energy exporter, exporting electricity to Ecuador and developing connections to Peru, Venezuela and Panama to export to those markets as well. The Trans-Caribbean pipeline connecting western Venezuela to Panama through Colombia is also under construction, thanks to cooperation between presidents Álvaro Uribe of Colombia, Martín Torrijos of Panama and Hugo Chávez of Venezuela. Coal is exported to Turkey.
Oil and coal account for 47% of goods exports in 2021.
The oil pipelines are a frequent target of extortion and bombing campaigns by the National Liberation Army (ELN) and, more recently, the Revolutionary Armed Forces of Colombia (FARC). The bombings, which have occurred on average once every 5 days, have caused substantial environmental damage, often in fragile rainforests and jungles, as well as causing significant loss of life. In April 1999 in Cartagena de Indias, Clinton's Secretary of Energy Bill Richardson spoke before investors from the United States, Canada and other countries. He expressed his government's willingness to use military aid to support the investment that they and their allies were going to make in Colombia, especially in strategically important sectors like mining and energy.
In 2001 there were 170 attacks on the Caño Limón–Coveñas pipeline. The pipeline was out of operation for over 200 days of that year; the government estimates that these bombings reduced Colombia's GDP by 0.5%. The government of the United States increased military aid, in 2003, to Colombia to assist in the effort to defend the pipeline. Occidental Petroleum privately contracted mercenaries who flew Skymaster planes, from AirScan International Inc., to patrol the Cano Limon-Covenas pipeline. Many of these operations used helicopters, equipment and weapons provided by the U.S. military and anti-narcotics aid programs.
Mining and natural exploitation has had environmental consequences. The region of Guajira is undergoing an accelerated desertification with the disappearances of forests, land, and water sources, due to the increase in coal production. Social consequences or lack of development in resource rich areas is common. 11 million Colombians survive on less than one dollar a day. Over 65% of these live in mining zones. There are 3.5 million children out of school, and the most critical situation is in the mining zone of Choco, Bolivar, and Sucre.
Economic consequences of privatization and liberal institutions have meant changes in taxation to attract foreign investment. Colombia will lose another $800 million over the next 90 years that Glencore International operates in El Cerrejon Zona Media, if the company continues to produce coal at a rate of 5 million tons/year, because of the reduction of the royalty tax from 10 to 15% to .04%. If the company, as is plausible, doubles or triples its production, the losses will be proportionally greater. The operational losses from the three large mining projects (El Cerrejon, La Loma, operated by Drummond, and Montelíbano, which produces ferronickel) for Colombia to more than 12 billion.
Coal production has grown rapidly, from 22.7 million tons in 1994 to 50.0 million tons in 2003. Over 90% of this amount was exported, making Colombia the world's sixth largest coal exporter, behind Australia, China, Indonesia, South Africa and Russia. From the mid-1980s the center of coal production was the Cerrejón mines in the Guajira department. However, the growth in output at La Loma in neighboring Cesar Department made this area the leader in Colombian coal production since 2004. Production in other departments, including Boyacá, Cundinamarca and Norte de Santander, forms about 13% of the total. The coal industry is largely controlled by international mining companies, including a consortium of BHP, Anglo American and Glencore at Cerrejón, and Conundrum Company at La Loma, which is undergoing a lawsuit in the U.S. District Court in Alabama for union assassinations and alleged paramilitary links.
Various attempts to open up the economy during the 1993-2023 period have been described by Portafolio as been "half-hearted". In 1990, to attract foreign investors and promote trade, an experiment from the International Monetary Fund known as "La Apertura" was adopted by the government, this policy was to modernize different sectors of the economy to increase the overall efficiency of production so as to bring down prices to internationally competitive levels. Although the analysis of the results are not clear, the fact is that the agricultural sector was severely impacted by this policy.
In 1991 and 1992, the government passed laws to stimulate foreign investment in nearly all sectors of the economy. The only activities closed to foreign direct investment are defense and national security, disposal of hazardous wastes, and real estate—the last of these restrictions is intended to hinder money laundering. Colombia established a special entity—Converter—to assist foreigners in making investments in the country. Foreign investment flows for 1999 were $4.4 billion, down from $4.8 billion in 1998.
Major foreign investment projects underway include the $6 billion development of the Cusiana and Cupiagua oil fields, development of coal fields in the north of the country, and the recently concluded licensing for establishment of cellular telephone service. The United States accounted for 26.5% of the total $19.4 billion stock of non-petroleum foreign direct investment in Colombia at the end of 1998.
On 21 October 1995, under the International Emergency Economic Powers Act (IEEPA), President Clinton signed an Executive Order barring U.S. entities from any commercial or financial transactions with four Colombian drug kingpins and with individuals and companies associated with the traffic in narcotics, as designated by the Secretary of the Treasury in consultation with the Secretary of State and the Attorney General. The list of designated individuals and companies is amended periodically and is maintained by the Office of Foreign Asset Control at the Department of the Treasury, tel. (202) 622-0077 (ask for Document #1900). The document also is available at the Department of Treasury web site.
Colombia is the United States' fifth-largest export market in Latin America—behind Mexico, Brazil, Venezuela, and Argentina—and the 26th-largest market for U.S. products worldwide. The United States is Colombia's principal trading partner, with two-way trade from November 1999 through November 2000 exceeding $9.5 billion--$3.5 billion U.S. exports and $6.0 billion U.S. imports. Colombia benefits from duty-free entry—for a 10-year period, through 2001—for certain of its exports to the United States under the Andean Trade Preferences Act. Colombia improved protection of intellectual property rights through the adoption of three Andean Pact decisions in 1993 and 1994, but the U.S. remains concerned over deficiencies in licensing, patent regulations, and copyright protection.
Colombia is also the largest export partner of the Dutch constituent country of Aruba (39.4%).
The petroleum and natural gas coal mining, chemical, and manufacturing industries attract the greatest U.S. investment interest. U.S. investment accounted for 37.8% ($4.2 billion) of the total $11.2 billion in foreign direct investment at the end of 1997, excluding petroleum and portfolio investment. Worker rights and benefits in the U.S.-dominated sectors are more favorable than general working conditions. Examples include shorter-than-average working hours, higher wages, and compliance with health and safety standards above the national average.
The services sector dominates Colombia's GDP, contributing 58 percent of GDP in 2007, and, given worldwide trends, its dominance will probably continue. The sector is characterized by its heterogeneity, being the largest for employment (61 percent), in both the formal and informal sectors.
Since the early 2010s, the Colombian government has shown interest in exporting modern Colombian pop culture to the world (which includes video games, music, movies, TV shows, fashion, cosmetics, and food) as a way of diversifying the economy and changing the image of Colombia. In the Hispanic world, Colombia is only behind Mexico in cultural exports at US$750 million annually, and is already a regional leader in cosmetic and beauty exports.
Tourism in Colombia is an important sector in the country's economy. Colombia has major attractions as a tourist destination, such as Cartagena and its historic surroundings, which are on the UNESCO World Heritage List; the insular department of San Andrés, Providencia y Santa Catalina; Santa Marta, Cartagena and the surrounding area. Fairly recently, Bogotá, the nation's capital, has become Colombia's major tourist destination because of its improved museums and entertainment facilities and its major urban renovations, including the rehabilitation of public areas, the development of parks, and the creation of an extensive network of cycling routes. With its very rich and varied geography, which includes the Amazon and Andean regions, the llanos, the Caribbean and Pacific coasts, and the deserts of La Guajira, and its unique biodiversity, Colombia also has major potential for ecotourism.
The direct contribution of Travel & Tourism to GDP in 2013 was COP11,974.3mn (1.7% of GDP). This is forecast to rise by 7.4% to COP12,863.4mn in 2014. This primarily reflects the economic activity generated by industries such as hotels, travel agents, airlines and other passenger transportation services (excluding commuter services). But it also includes, for example, the activities of the restaurant and leisure industries directly supported by tourists. The direct contribution of Travel & Tourism to GDP is expected to grow by 4.1% pa to COP19,208.4mn (1.8% of GDP) by 2024.
The number of tourists in Colombia grows by over 12% every year. Colombia is projected to have over 15 million tourists by 2023.
Eco-tourism is very promising in Colombia. Colombia has vast coastlines, mountainous areas, and tropical jungles. There are volcanoes and waterfalls as well. This makes Colombia a biodiverse country with many attractions for foreign visitors.
The Colombian coffee growing axis (Spanish: Eje Cafetero), also known as the Coffee Triangle (Spanish: Triángulo del Café), is a part of the Colombian Paisa region in the rural area of Colombia, which is famous for growing and production of a majority of Colombian coffee, considered by some as the best coffee in the world. There are three departments in the area: Caldas, Quindío and Risaralda. These departments are among the smallest departments in Colombia with a total combined area of 13873 km (5356 mi), about 1.2% of the Colombian territory. The combined population is 2,291,195 (2005 census).
Colombia's geography, with three cordilleras of the Andes running up the country from south to north, and jungle in the Amazon and Darién regions, represents a major obstacle to the development of national road networks with international connections. Thus, the basic nature of the country's transportation infrastructure is not surprising. In the spirit of the 1991 constitution, in 1993 the Ministry of Public Works and Transportation was reorganized and renamed the Ministry of Transportation. In 2000 the new ministry strengthened its role as the planner and regulator within the sector.
Colombia was a pioneer in promoting airlines in an effort to overcome its geographic barriers to transportation. The Colombian Company of Air Navigation, formed in 1919, was the second commercial airline in the world. It was not until the 1940s that Colombia's air transportation began growing significantly in the number of companies, passengers carried, and kilometers covered. In the early 2000s, an average of 72 percent of the passengers transported by air go to national destinations, while 28 percent travel internationally. One notable feature is that after the reforms of the beginning of the 1990s, the number of international passengers tripled by 2003. In 1993 the construction, administration, operation, and maintenance of the main airports transferred to departmental authorities and the private sector, including companies specializing in air transportation. Within this process, in 2006 the International Airport Operator (Opain), a Swiss-Colombian consortium, won the concession to manage and develop Bogotá's El Dorado International Airport. El Dorado is the largest airport in Latin America in terms of cargo traffic (33rd worldwide), with 622,145 metric tons in 2013, second in terms of traffic movements (45th worldwide) and third in terms of passengers (50th among the busiest airports in the world). In addition to El Dorado, Colombia's international airports are Palo Negro in Bucaramanga, Simón Bolívar in Santa Marta, Cortissoz in Barranquilla, Rafael Núñez in Cartagena, José María Córdova in Rionegro near Medellín, Alfonso Bonilla Aragón in Cali, Alfredo Vásquez Cobo in Leticia, Matecaña in Pereira, Gustavo Rojas Pinilla in San Andrés, and Camilo Daza in Cúcuta. In 2006 Colombia was generally reported to have a total of 984 airports, of which 103 had paved runways and 883 were unpaved. The Ministry of Transportation listed 581 airports in 2007, but it may have used a different methodology for counting them.
After a large crisis in 1999, poverty in Colombia has had a decreasing trend. The share of Colombians below the income-based poverty line fell from 50% in 2002 to 28% in 2016. The share of Colombians below the extreme income-based poverty line fell from 18% to 9% in the same period. Multidimensional poverty fell from 30% to 18% between 2010 and 2016.
Colombia has a Gini coefficient of 51.7.
Hypermarkets and big-box stores are losing market participation in Colombian retail.
Between 1976 and 2006, Colombia's debt doubled every 10 years: in 1976 it was about $3.6 billion, in 1986 it was $7.2 billion, in 1996 it was over $16 billion and in 2006 it was over $36 billion. Since 2006, the growth of the debt has accelerated: it reached $72 billion in 2011 and reached $124 billion in 2017, which means that in less than 10 years Colombia's foreign debt has tripled. About a quarter of Colombia's annual budget, or $20 billion, goes to pay off the public debt.
Corruption in public management in Colombia is widespread and structural in nature. This situation generates losses for the country estimated at around 15 billion dollars. Colombia has not escaped the scandals involving millions of dollars in bribes from the Brazilian construction company Odebrecht, as well as the Cartagena refinery, a case of embezzlement of public funds that came to light in 2016 and involved members of the governments of Álvaro Uribe (2002-2010) and Juan Manuel Santos (2010-2018). | [

It was not until the 1940s that Colombia's air transportation began growing significantly in the number of companies, passengers carried, and kilometers covered. In the early 2000s, an average of 72 percent of the passengers transported by air go to national destinations, while 28 percent travel internationally. One notable feature is that after the reforms of the beginning of the 1990s, the number of international passengers tripled by 2003. In 1993 the construction, administration, operation, and maintenance of the main airports transferred to departmental authorities and the private sector, including companies specializing in air transportation. Within this process, in 2006 the International Airport Operator (Opain), a Swiss-Colombian consortium, won the concession to manage and develop Bogotá's El Dorado International Airport. El Dorado is the largest airport in Latin America in terms of cargo traffic (33rd worldwide), with 622,145 metric tons in 2013, second in terms of traffic movements (45th worldwide) and third in terms of passengers (50th among the busiest airports in the world). In addition to El Dorado, Colombia's international airports are Palo Negro in Bucaramanga, Simón Bolívar in Santa Marta, Cortissoz in Barranquilla, Rafael Núñez in Cartagena, José María Córdova in Rionegro near Medellín, Alfonso Bonilla Aragón in Cali, Alfredo Vásquez Cobo in Leticia, Matecaña in Pereira, Gustavo Rojas Pinilla in San Andrés, and Camilo Daza in Cúcuta. In 2006 Colombia was generally reported to have a total of 984 airports, of which 103 had paved runways and 883 were unpaved. The Ministry of Transportation listed 581 airports in 2007, but it may have used a different methodology for counting them.",

] | The economy of Colombia is the fourth largest in Latin America as measured by gross domestic product and the third-largest economic power in South America. Colombia has experienced a historic economic boom over the last decade. Throughout most of the 20th century, Colombia was Latin America's 4th and 3rd largest economy when measured by nominal GDP, real GDP, GDP (PPP), and real GDP at chained PPPs. Between 2012 and 2014, it became the 3rd largest in Latin America by nominal GDP. As of 2018, the GDP (PPP) per capita has increased to over US$14,000, and real gross domestic product at chained PPPs increased from US$250 billion in 1990 to nearly US$800 billion. Poverty levels were as high as 65% in 1990, but decreased to under 30% by 2014, and 27% by 2018. They decreased by an average of 1.35% per year since 1990. Petroleum is Colombia's main export, representing over 45% of Colombia's exports. Manufacturing represents nearly 12% of Colombia's exports, and grows at a rate of over 10% a year. Colombia has the fastest growing information technology industry in the world, and has the longest fibre optic network in Latin America. Colombia also has one of the largest shipbuilding industries in the world outside Asia. Modern industries like shipbuilding, electronics, automobile, tourism, construction, and mining, grew dramatically during the 2000s and 2010s. However, most of Colombia's exports are still commodity-based. Colombia is Latin America's 2nd-largest producer of domestically made electronics and appliances, following Mexico. Colombia had the fastest-growing major economy in the Western world in 2014, behind only China worldwide. Since the early 2010s, the Colombian government has shown interest in exporting modern Colombian pop culture to the world as a way of diversifying the economy and entirely changing the image of Colombia. This has inspired a national campaign, similar to the Korean Wave. Colombia is only behind Mexico in cultural exports, and is already a regional leader in cosmetic and beauty exports. Wealth is poorly distributed, since with a Gini index of approximately 0.̟6, Colombia is among the most unequal societies in the world. For example, according to the World Bank, in 2010 the richest 20% of the population owned 60.2% of the wealth and the poorest 20% only 3%, and 15.8% of Colombians lived on less than $2 a day. In 2021, more than 54% of Colombian families are food insecure and more than 560,000 children under the age of five are chronically undernourished. The informal economy is estimated at 47% in 2020. There is no welfare state in Colombia, which has almost no unemployment or pension insurance system. As a result, only one million elderly people have pensions and social assistance is very low. Many people in their 70s and 80s are forced to continue working or beg. The country is said to be the most unequal in the Organisation for Economic Co-operation and Development (OECD). | 2002-02-25T15:43:11Z | 2023-12-18T17:40:15Z | [

5,840 | Communications in Colombia | Since being liberalized in 1991, the Colombian telecommunications sector has added new services, expanded coverage, improved efficiency, and lowered costs. The sector has had the second largest (after energy) investment in infrastructure (54 percent) since 1997. However, the economic downturn between 1999 and 2002 adversely affected telecommunications. During this period, Colombia's telecommunications industry lost US$2 billion despite a profit of US$1 billion in local service. In June 2003, the government liquidated the state-owned and heavily indebted National Telecommunications Company (Empresa Nacional de Telecomunicaciones—Telecom) and replaced it with Colombia Telecomunicaciones (Colombia Telecom). The measure enabled the industry to expand rapidly, and in 2004 it constituted 2.8 percent of gross domestic product (GDP). Telefónica of Spain acquired 50 percent plus one share of the company in 2006.
As a result of increasing competition, Colombia has a relatively modern telecommunications infrastructure that primarily serves larger towns and cities. Colombia's telecommunication system includes access to 8 different international Submarine cable systems, INTELSAT, 11 domestic satellite Earth stations, and a nationwide microwave radio relay system.
The country's teledensity (the density of telephone lines in a community) is relatively high for Latin America (17 percent in 2006). However, there is a steep imbalance between rural and urban areas, with some regions below 10 percent and the big cities exceeding 30 percent. Bogotá, Medellín, and Cali account for about 50 percent of telephone lines in use. By the end of 2005, the number of telephone main lines in use totaled 7,851,649. Colombia Telecom accounted for only about 31 percent of these lines; 27 other operators accounted for the rest.
Colombia's mobile market is one of the fastest-growing businesses in the country. In 1993, the first mobile phone call was made. In mid-2004 mobile telephones overtook fixed lines in service for the first time. By 2005 Colombia had the highest mobile phone density (90 percent) in Latin America, as compared with the region's average density of 70 percent. The number of mobile telephone subscribers totaled an estimated 31 million in 2007, as compared to 21.8 million in 2005 and 6.8 million in 2001.
In late 2004, Radio Televisión Nacional de Colombia (RTVC) replaced the liquidated Inravisión (Instituto Nacional de Radio y Televisión) as the government-run radio and television broadcasting service, which oversees three national television stations and five radio companies (which operate about a dozen principal networks). Colombia has about 60 television stations, including seven low-power stations. In 2000 the population had about 11.9 million television receivers in use. Of the approximately 515 radio stations, 454 are AM; 34, FM; and 27, shortwave.
As of 2016, Colombia has access to the following international Submarine cable systems: SAC/LAN, Maya-1, AMX-1, Pan Am, SAm-1, ARCOS-1, CFX-1, and PCCS. These cables land at 4 locations in the Caribbean: Barranquilla, Cartagena, Riohacha, and Tolu. One cable lands on the Pacific Ocean coast at Buenaventura, Valle del Cauca.
Colombia is still far behind Brazil, Mexico, and Argentina in terms of online usage. It had an estimated total of 900,000 Internet subscribers by the end of 2005, a figure that equated to 4,739,000 Internet users, or 11.5 percent of the 2005 population (10.9 per 100 inhabitants). By late 2009 39% of households had internet access Colombia had 581,877 Internet hosts in 2006. Although as many as 70 percent of Colombians accessed the Internet over their ordinary telephone lines, dial-up access is losing ground to broadband. In 2005 Colombia had 345,000 broadband subscriber lines, or one per 100 inhabitants. In 2006 the number of personal computers per 1,000 people increased to an estimated 87 per 1,000 inhabitants, a rate still below that in other large Latin American economies.

5,841 | Transport in Colombia | Transport in Colombia is regulated by the Ministry of Transport.
Road travel is the main means of transport; 69 percent of cargo is transported by road, as compared with 27 percent by railroad, 3 percent by internal waterways, and 1 percent by air.
The indigenous peoples in Colombia used and some continue to use the waterways as the way of transportation using rafts and canoes.
With the arrival of the Europeans the Spaniards brought the horses, mules and donkey (which developed into the Paso Fino) used by them in ranching duties later in the Spanish colonization of the Americas. Horses contributed greatly to the transport of the Spanish conquerors and colonizers. They also introduced the wheel, and brought wooden carts and carriages to facilitate their transport. The Spaniards also developed the first roads, rudimentary and most of these in the Caribbean region. Due to the rough terrain of Colombia communications between regions was difficult and affected the effectiveness of the central government creating isolation in some regions. Maritime navigation developed locally after Spain lifted its restrictions on ports within the Spanish Empire inducing mercantilism. Spanish also transported African slaves and forcedly migrated many indigenous tribes throughout Colombia.
With the independence and the influences of the European Industrial Revolution the main way of transport in Colombia became the navigation mainly through the Magdalena River which connected Honda in inland Colombia, with Barranquilla by the Caribbean sea to the trade with the United States and Europe. This also brought a large wave of immigrants from European and Middle Eastern countries. The industrialization process and transportation in Colombia were affected by the internal civil wars that surged after the independence from Spain and that continued throughout the 19th and 20th centuries.
During the late 19th century European and American companies introduced railways to carry to the ports the local production of raw materials intended for exports and also imports from Europe. Steam ships began carrying Colombians, immigrants and goods from Europe and the United States over the Magdalena River.
The Ministry of Transport was created in 1905 during the Presidency of Rafael Reyes under the name of Ministerio de Obras Públicas y Transporte or Ministry of Public Works and Transport with the main function of taking care of national assets issues, including mines, oil (fuel), patents and trade marks, railways, roads, bridges, national buildings and land without landowners.
In the early 20th century roads and highways maintenance and construction regulations were established. Rivers were cleaned, dragged and channeled and the navigational industry was organized. The Public works districts were created, as well as the Ferrocarriles Nacionales de Colombia (National Railways of Colombia). Among other major projects developed were the aqueduct of Bogotá, La Regadera Dam and the Vitelma Water Treatment Plant. The Ministry also created the National Institute of Transit (from the Spanish Instituto Nacional de Tránsito), (INTRA) under the Transport and tariffs Directorate and was in charge of designing the first National roads plan with the support of many foreign multinational construction companies.
Aviation was born in Barranquilla with the creation of SCADTA in 1919 a joint venture between Colombians and Germans that delivered mail to the main cities of Colombia which later merged with SACO to form Avianca.
Colombia has 3,034 kilometers (1,885 mi) of rail lines, 150 kilometers (93 mi) of which are 1,435 mm (4 ft 8+1⁄2 in) gauge and 3,154 kilometers (1,960 mi) of which are 914 mm (3 ft) gauge. However, only 2,611 kilometers (1,622 mi) of lines are still in use. Rail transport in Colombia remains underdeveloped. The national railroad system, once the country's main mode of transport for freight, has been neglected in favor of road development and now accounts for only about a quarter of freight transport. Passenger-rail use was suspended in 1992 resumed at the end of the 1990s, and as of 2017 it is considered abandoned (at least for long distances). Fewer than 165,000 passenger journeys were made in 1999, as compared with more than 5 million in 1972, and the figure was only 160,130 in 2005. The two still-functioning passenger trains are: one between Puerto Berrío and García Cadena, and another one between Bogotá and Zipaquirá. Short sections of railroad, mainly the Bogotá-Atlantic rim, are used to haul goods, mostly coal, to the Caribbean and Pacific ports. In 2005 a total of 27.5 million metric tons of cargo were transported by rail. Although the nation's rail network links seven of the country's 10 major cities, very little of it has been used regularly because of security concerns, lack of maintenance, and the power of the road transport union. During 2004–6, approximately 2,000 kilometers of the country's rail lines underwent refurbishment. This upgrade involved two main projects: the 1,484-kilometer line linking Bogotá to the Caribbean Coast and the 499-kilometer Pacific coastal network that links the industrial city of Cali and the surrounding coffee-growing region to the port of Buenaventura.
The three main north–south highways are the Caribbean, Eastern, and Central Trunk Highways (troncales). Estimates of the length of Colombia's road system in 2004 ranged from 115,000 kilometers to 145,000 kilometers, of which fewer than 15 percent were paved. However, according to 2005 data reported by the Colombian government, the road network totaled 163,000 kilometers, 68 percent of which were paved and in good condition. The increase may reflect some newly built roads. President Uribe has vowed to pave more than 2,500 kilometers of roads during his administration, and about 5,000 kilometers of new secondary roads were being built in the 2003–6 period. Despite serious terrain obstacles, almost three-quarters of all cross-border dry cargo is now transported by road, 105,251 metric tons in 2005.
Highways are managed by the Colombian Ministry of Transport through the National Roads Institute. The security of the highways in Colombia is managed by the Highway Police unit of the Colombian National Police. Colombia is crossed by the Panamerican Highway.
Seaports handle around 80 percent of international cargo. In 2005 a total of 105,251 metric tons of cargo were transported by water. Colombia's most important ocean terminals are Barranquilla, Cartagena, and Santa Marta on the Caribbean Coast and Buenaventura and Tumaco on the Pacific Coast. Exports mostly pass through the Caribbean ports of Cartagena and Santa Marta, while 65 percent of imports arrive at the port of Buenaventura. Other important ports and harbors are Bahía de Portete, Leticia, Puerto Bolívar, San Andrés, Santa Marta, and Turbo. Since privatization was implemented in 1993, the efficiency of port handling has increased greatly. Privatization, however, has had negative impacts as well. In Buenaventura, for example, privatization of the harbor has increased unemployment and social issues. There are plans to construct a deep-water port at Bahía Solano.
The main inland waterways total about 18,200 kilometers, 11,000 kilometers of which are navigable by riverboats. A well-developed and important form of transport for both cargo and passengers, inland waterways transport approximately 3.8 million metric tons of freight and more than 5.5 million passengers annually. Main inland waterways are the Magdalena–Cauca River system, which is navigable for 1,500 kilometers; the Atrato, which is navigable for 687 kilometers; the Orinoco system of more than five navigable rivers, which total more than 4,000 kilometers of potential navigation (mainly through Venezuela); and the Amazonas system, which has four main rivers totaling 3,000 navigable kilometers (mainly through Brazil). The government is planning an ambitious program to more fully utilize the main rivers for transport. In addition, the navy's riverine brigade has been patrolling waterways more aggressively in order to establish safer river transport in the more remote areas in the south and east of the country.
The merchant marine totals 17 ships (1,000 gross registered tons or more), including four bulk, 13 cargo, one container, one liquefied gas, and three petroleum tanker ships. Colombia also has seven ships registered in other countries (Antigua and Barbuda, two; Panama, five).
The Special Administrative Unit of Civil Aeronautics is responsible of regulating and controlling the use of air space by civil aviation. The customs/immigration issues are controlled by the Departamento Administrativo de Seguridad (DAS).
Colombia has well-developed air routes and an estimated total of 984 airports, 100 of which have paved runways, plus two heliports. Of the 74 main airports, 20 can accommodate jet aircraft. Two airports are more than 3,047 meters in length, nine are 2,438–3,047 meters, 39 are 1,524–2,437 meters, 38 are 914–1,523 meters, 12 are shorter than 914 meters, and 880 have unpaved runways. The government has been selling its stake in local airports in order to allow their privatization. The country has 40 regional airports, and the cities of Bogotá, Medellín, Cali, Barranquilla, Bucaramanga, Cartagena, Cúcuta, Leticia, Pereira, Armenia, San Andrés, and Santa Marta have international airports. Bogotá's El Dorado International Airport handles 550 million metric tons of cargo and 22 million passengers a year, making it the largest airport in Latin America in terms of cargo and the third largest in passenger numbers.
Urban transport systems have been developed in Barranquilla, Bogotá, Cali, and Medellín. Traffic congestion in Bogotá had been greatly exacerbated by a lack of rail transport; however, this problem was alleviated, to a degree, by the formation of one of the world's most expansive and highest-capacity bus rapid transit (BRT) systems—known as the TransMilenio (opened 2000)—and the restriction of vehicles through a daily, rotating ban on private cars (depending on plate numbers). Bogotá's BRT consists of bus and minibus services managed by both private- and public-sector enterprises.
Since 1995, Medellín has had a modern urban railway, the Metro de Medellín, utilizing two train lines with 27 stations. The Metro also connects with the cities of Itagüí, Envigado, and Bello. An elevated gondola-cablecar system, the Metrocable, opened in 2004 to improve Metro accessibility for some of the city’s more isolated, dense barrios. The gondola design was specifically chosen due to the mountainous geography of the city, with most of the neighborhoods served being reasonably higher in elevation from the city center. A BRT line called Transmetro began operating in 2011, with a second line added in 2013.
Other Colombian cities have also installed BRT systems, such as Cali, with a six-line system (opened 2008), Barranquilla with two lines (opened 2010), Bucaramanga with one line (opened 2010), Cartagena with one line (opened 2015) and Pereira, with three lines (opened 2006). A future light rail line in Barranquilla is planned.
Colombia has 4,350 kilometers of gas pipelines, 6,134 kilometers of oil pipelines, and 3,140 kilometers of refined-products pipelines. The country has five major oil pipelines, four of which connect with the Caribbean export terminal at Puerto Coveñas. Until at least September 2005, the United States funded efforts to help protect a major pipeline, the 769-kilometer-long Caño Limón–Puerto Coveñas pipeline, which carries about 20 percent of Colombia's oil production to Puerto Coveñas from the guerrilla-infested Arauca region in the eastern Andean foothills and Amazonian jungle. The number of attacks against pipelines began declining substantially in 2002. In 2004 there were only 17 attacks against the Caño Limón–Puerto Coveñas pipeline, down from 170 in 2001. However, a bombing in February 2005 shut the pipeline for several weeks, and attacks against the electrical gird system that provides energy to the Caño Limón oilfield have continued. New oil pipeline projects with Brazil and Venezuela are underway. In addition, the already strong cross-border trade links between Colombia and Venezuela were solidified in July 2004 with an agreement to build a US$320 million natural gas pipeline between the two countries, to be completed in 2008. | [

This also brought a large wave of immigrants from European and Middle Eastern countries. The industrialization process and transportation in Colombia were affected by the internal civil wars that surged after the independence from Spain and that continued throughout the 19th and 20th centuries.",

However, only 2,611 kilometers (1,622 mi) of lines are still in use. Rail transport in Colombia remains underdeveloped. The national railroad system, once the country's main mode of transport for freight, has been neglected in favor of road development and now accounts for only about a quarter of freight transport. Passenger-rail use was suspended in 1992 resumed at the end of the 1990s, and as of 2017 it is considered abandoned (at least for long distances). Fewer than 165,000 passenger journeys were made in 1999, as compared with more than 5 million in 1972, and the figure was only 160,130 in 2005. The two still-functioning passenger trains are: one between Puerto Berrío and García Cadena, and another one between Bogotá and Zipaquirá. Short sections of railroad, mainly the Bogotá-Atlantic rim, are used to haul goods, mostly coal, to the Caribbean and Pacific ports. In 2005 a total of 27.5 million metric tons of cargo were transported by rail. Although the nation's rail network links seven of the country's 10 major cities, very little of it has been used regularly because of security concerns, lack of maintenance, and the power of the road transport union. During 2004–6, approximately 2,000 kilometers of the country's rail lines underwent refurbishment. This upgrade involved two main projects: the 1,484-kilometer line linking Bogotá to the Caribbean Coast and the 499-kilometer Pacific coastal network that links the industrial city of Cali and the surrounding coffee-growing region to the port of Buenaventura.",

5,843 | Military Forces of Colombia | The Military Forces of Colombia (Spanish: Fuerzas Militares de Colombia) are the unified armed forces of the Republic of Colombia. They consist of the Colombian Army, the Colombian Navy and the Colombian Aerospace Force. The National Police of Colombia, although technically not part of the military, is controlled and administered by the Ministry of National Defence, and national conscription also includes service in the National Police, thus making it a de facto gendarmerie and a branch of the military. The President of Colombia is the military's commander in chief, and helps formulate defense policy through the Ministry of National Defence, which is in charge of day-to-day operations.
The Military Forces of Colombia have their roots in the Army of the Commoners (Ejército de los Comuneros), which was formed on 7 August 1819 – before the establishment of the present day Colombia – to meet the demands of the Revolutionary War against the Spanish Empire. After their triumph in the war, the Army of the Commoners disbanded, and the Congress of Angostura created the Gran Colombian Army to replace it, thus establishing the first military service branch of the country.
The Colombian military was operationally involved in World War II and was the only Latin American country to send troops to the Korean War. Ever since the advent of the Colombian Conflict, the Colombian military has been involved in combat, pacification, counter-insurgency, and drug interdiction operations all over the country's national territory. Recently it has participated in counter-piracy efforts in the Horn of Africa under Operation Ocean Shield and Operation Atlanta.
The military of Colombia is the third largest in the Western Hemisphere in terms of active personnel and has the fourth largest expenditure in the Americas, behind the United States Armed Forces, the Canadian Armed Forces and the Brazilian Armed Forces respectively.
The Colombian Constitution includes two overlapping definitions of what could be defined as 'armed forces' in English:
This is a subtle yet important distinction, both in terms of emphasizing the civil nature of the National Police, but also adapting the national police to function as a paramilitary force which can perform military duties as a result of the Colombian Conflict. This has led to some of the most important police units adopting military training and conducting special operations alongside the Colombian Army, Aerospace Force, and Navy. Therefore, the functions of the Colombian Police in practical terms are similar to those of a gendarmerie, like the Spanish Civil Guard and the Carabineros de Chile, which maintain military ranks for all police personnel.
The Colombian armed forces consist of: Military Forces:
And,
Public Force strength as of April 2014.
In 2000, Colombia assigned 3.9% of its GDP to defense. By 2008 this figure had risen to 4.8%, ranking it 14th in the world. The armed forces number about 250,000 uniformed personnel: 145,000 military and 105,000 police. These figures do not include assistance personnel such as cooks, medics, mechanics, and so on. This makes the Colombian military one of the largest and most well-equipped in Latin America. Many Colombian military personnel have received military training assistance directly in Colombia and also in the United States. The United States has provided equipment and financing to the Colombian military and police through the military assistance program, foreign military sales, and the international narcotics control program, all currently united under the auspices of Plan Colombia. | [

5,844 | History of Colombia | The history of Colombia includes the settlements and society by indigenous peoples, most notably, the Muisca Confederation, Quimbaya Civilization, and Tairona Chiefdoms; the Spanish arrived in 1492 and initiated a period of annexation and colonization, most noteworthy being Spanish conquest; ultimately creating the Viceroyalty of New Granada, with its capital at Bogotá. Independence from Spain was won in 1819, but by 1830 the "Gran Colombia" Federation was dissolved. What is now Colombia and Panama emerged as the Republic of New Granada. The new nation experimented with federalism as the Granadine Confederation (1858), and then the United States of Colombia (1863), before the Republic of Colombia was finally declared in 1886; as well as constant political violence in the country. Panama seceded in 1903. Since the 1960s, the country has suffered from an asymmetric low-intensity armed conflict, which escalated in the 1990s, but then decreased from 2005 onward. The legacy of Colombia's history has resulted in a rich cultural heritage; while varied geography, and the imposing landscape of the country has resulted in the development of very strong regional identities.
From approximately 12,000 years BP onwards, hunter-gatherer societies existed near present-day Bogotá (at El Abra and Tequendama), and they traded with one another and with cultures living in the Magdalena River valley. Due to its location, the present territory of Colombia was a corridor of early human migration from Mesoamerica and the Caribbean to the Andes and the Amazon basin. The oldest archaeological finds are from the Pubenza archaeological site and El Totumo archaeological site in the Magdalena Valley 100 kilometres (62 mi) southwest of Bogotá. These sites date from the Paleoindian period (18,000–8000 BCE). At Puerto Hormiga archaeological site and other sites, traces from the Archaic period in South America (~8000–2000 BCE) have been found. Vestiges indicate that there was also early occupation in the regions of El Abra, Tibitó and Tequendama in Cundinamarca. The oldest pottery discovered in the Americas, found at San Jacinto archaeological site, dates to 5000–4000 BCE. Indigenous people inhabited the territory that is now Colombia by 10,500 BCE. Nomadic hunter-gatherer tribes at the El Abra and Tequendama sites near present-day Bogotá traded with one another and with other cultures from the Magdalena River Valley.
Serranía La Lindosa, a mountainous region of Guaviare Department is known for an extensive prehistoric rock art site which stretches for nearly eight miles. The site, near to the Guayabero River was discovered in 2019, but was not revealed to the public until 2020. There are tens of thousands of paintings of animals and humans created up to 12,500 BP. Images of now-extinct ice age animals, such as the mastodon, helped date the site. Other ice-age animals depicted include the palaeolama, giant sloths and ice age horses. The site has gone undiscovered because of a conflict between the government and the Farc. The remote site is a two-hour drive from San José del Guaviare, followed by a four hour trek. The site was discovered by a team from National University of Colombia, University of Antioquia and the University of Exeter as part of a project funded by European Research Council as part of the Horizon 2020 Framework Programmes for Research and Technological Development. The site is to be featured in episode 2 of the Channel 4 series, Jungle Mystery: Lost Kingdoms of the Amazon, on 12 December 2020.
Between 5000 and 1000 BCE, hunter-gatherer tribes transitioned to agrarian societies; fixed settlements were established, and pottery appeared. Beginning in the 1st millennium BCE, groups of Amerindians including the Muisca, Quimbaya, Tairona, Calima, Zenú, Tierradentro, San Agustín, Tolima, and Urabá became skilled in farming, mining, and metalcraft; and some developed the political system of cacicazgos with a pyramidal structure of power headed by caciques. The Muisca inhabited mainly the area of what is now the Departments of Boyacá and Cundinamarca high plateau (Altiplano Cundiboyacense) where they formed the Muisca Confederation. The Muisca had one of the most developed political systems (Muisca Confederation) in South America, surpassed only by the Incas. They farmed maize, potato, quinoa and cotton, and traded gold, emeralds, blankets, ceramic handicrafts, coca and especially salt with neighboring nations. The Tairona inhabited northern Colombia in the isolated Andes mountain range of Sierra Nevada de Santa Marta. The Quimbaya inhabited regions of the Cauca River Valley between the Western and Central Ranges. The Incas expanded their empire on the southwest part of the country.
Europeans first visited the territory that became Colombia in 1499 when the first expedition of Alonso de Ojeda arrived at the Cabo de la Vela. The Spanish made several attempts to settle along the north coast of today's Colombia in the early 16th century, but their first permanent settlement, at Santa Marta, dates from 1525. The Spanish commander Pedro de Heredia founded Cartagena on June 1, 1533 in the former location of the indigenous Caribbean Calamarí village. Cartagena grew rapidly, fueled first by the gold in the tombs of the Sinú Culture, and later by trade. The thirst for gold and land lured Spanish explorers to visit Chibchan-speaking areas; resulting in the Spanish conquest of the Chibchan Nations - the conquest by the Spanish monarchy of the Chibcha language-speaking nations, mainly the Muisca and Tairona who inhabited present-day Colombia, beginning the Spanish colonization of the Americas.
The Spanish advance inland from the Caribbean coast began independently from three different directions, under Jimenéz de Quesáda, Sebastián de Benalcázar (known in Colombia as Belalcázar) and Nikolaus Federmann. Although all three were drawn by the Indian treasures, none intended to reach Muisca territory, where they finally met. In August 1538, Quesáda founded Santa Fe de Bogotá on the site of Muisca village of Bacatá.
In 1549, the institution of the Spanish Royal Audiencia in Bogotá gave that city the status of capital of New Granada, which comprised in large part what is now the territory of Colombia. As early as the 1500s however, secret anti-Spanish discontentment was already brewing for Colombians since Spain prohibited direct trade between the Viceroyalty of Peru, which included Colombia, and the Viceroyalty of New Spain, which included the Philippines the source of Asian products like silk and porcelain which was in demand in the Americas. Illegal trade between Peruvians, Filipinos, and Mexicans continued in secret, as smuggled Asian goods ended up in Córdoba, Colombia, the distribution center for illegal Asian imports, due to the collusion between these peoples against the authorities in Spain. They settled and traded with each other while disobeying the forced Spanish monopoly in more expensive silks and porcelain made in homeland Spain. In 1717, the Viceroyalty of New Granada was originally created, and then it was temporarily removed, to finally be reestablished in 1739. The Viceroyalty had Santa Fé de Bogotá as its capital. This Viceroyalty included some other provinces of northwestern South America which had previously been under the jurisdiction of the Viceroyalties of New Spain or Peru and correspond mainly to today's Venezuela, Ecuador and Panama. So, Bogotá became one of the principal administrative centers of the Spanish possessions in the New World, along with Lima and Mexico City.
From then on, the long independence struggle was led mainly by Bolívar and Francisco de Paula Santander in neighboring Venezuela. Bolívar returned to New Granada only in 1819 after establishing himself as leader of the pro-independence forces in the Venezuelan llanos. From there he led an army over the Andes and captured New Granada after a quick campaign that ended at the Battle of Boyacá, on August 7, 1819. (For more information, see Military career of Simón Bolívar.)
That year, the Congress of Angostura established the Republic of Gran Colombia, which included all territories under the jurisdiction of the former Viceroyalty of New Granada. Bolívar was elected the first president of Gran Colombia and Santander, vice president.
As the Federation of Gran Colombia was dissolved in 1830, the Department of Cundinamarca (as established in Angostura) became a new country, the Republic of New Granada.
In 1863 the name of the Republic was changed officially to "United States of Colombia", and in 1886 the country adopted its present name: "Republic of Colombia".
Two political parties grew out of conflicts between the followers of Bolívar and Santander and their political visions—the Conservatives and the Liberals – and have since dominated Colombian politics. Bolívar's supporters, who later formed the nucleus of the Conservative Party, sought strong centralized government, alliance with the Roman Catholic Church, and a limited franchise. Santander's followers, forerunners of the Liberals, wanted a decentralized government, state rather than church control over education and other civil matters, and a broadened suffrage.
Throughout the 19th and early 20th centuries, each party held the presidency for roughly equal periods of time. Colombia maintained a tradition of civilian government and regular, free elections. The military has seized power three times in Colombia's history: in 1830, after the dissolution of Great Colombia; again in 1854 (by General José María Melo); and from 1953 to 1957 (under General Gustavo Rojas Pinilla). Civilian rule was restored within one year in the first two instances.
Notwithstanding the country's commitment to democratic institutions, Colombia's history has also been characterized by widespread, violent conflict. Two civil wars resulted from bitter rivalry between the Conservative and Liberal parties. The Thousand Days' War (1899–1902) cost an estimated 100,000 lives, and up to 300,000 people died during "La Violencia" of the late 1940s and 1950s, a bipartisan confrontation which erupted after the assassination of Liberal popular candidate Jorge Eliécer Gaitán. United States activity to influence the area (especially the Panama Canal construction and control) led to a military uprising in the Isthmus Department in 1903, which resulted in the separation and independence of Panama.
A military coup in 1953 toppled the right-wing government of Conservative Laureano Gómez and brought General Gustavo Rojas Pinilla to power. Initially, Rojas enjoyed considerable popular support, due largely to his success in reducing "La Violencia". When he did not restore democratic rule and occasionally engaged in open repression, however, he was overthrown by the military in 1957 with the backing of both political parties, and a provisional government was installed.
In July 1957, former Conservative President Laureano Gómez (1950–1953) and former Liberal President Alberto Lleras (1945–1946, 1958–1962) issued the "Declaration of Sitges," in which they proposed a "National Front," whereby the Liberal and Conservative parties would govern jointly. The presidency would be determined by an alternating conservative and liberal president every 4 years for 16 years; the two parties would have parity in all other elective offices.
The National Front ended "La Violencia", and National Front administrations attempted to institute far-reaching social and economic reforms in cooperation with the Alliance for Progress. In particular, the Liberal president Alberto Lleras Camargo (1958–1962) created the Colombian Institute for Agrarian Reform (INCORA), and Carlos Lleras Restrepo (1966–1970) further developed land entitlement. In 1968 and 1969 alone, the INCORA issued more than 60,000 land titles to farmers and workers.
In the end, the contradictions between each successive Liberal and Conservative administration made the results decidedly mixed. Despite the progress in certain sectors, many social and political injustices continued.
The National Front system itself eventually began to be seen as a form of political repression by dissidents and even many mainstream voters, and many protesters were victimized during this period. Especially after what was later confirmed as the fraudulent election of Conservative candidate Misael Pastrana in 1970, which resulted in the defeat of the relatively populist candidate and former president (dictator) Gustavo Rojas Pinilla. The M-19 guerrilla movement, "Movimiento 19 de Abril" (19 April Movement), would eventually be founded in part as a response to this particular event. The FARC was formed in 1964 by Manuel Marulanda Vélez and other Marxist–Leninist supporters, after a military attack on the community of Marquetalia.
Although the system established by the Sitges agreement was phased out by 1974, the 1886 Colombian constitution — in effect until 1991—required that the losing political party be given adequate and equitable participation in the government which, according to many observers and later analysis, eventually resulted in some increase in corruption and legal relaxation. The current 1991 constitution does not have that requirement, but subsequent administrations have tended to include members of opposition parties.
From 1974 until 1982, different presidential administrations chose to focus on ending the persistent insurgencies that sought to undermine Colombia's traditional political system. Both groups claimed to represent the poor and weak against the rich and powerful classes of the country, demanding the completion of true land and political reform, from an openly Communist perspective.
By 1974, another challenge to the state's authority and legitimacy had come from 19th of April Movement (M-19), a mostly urban guerrilla group founded in response to an alleged electoral fraud during the final National Front election of Misael Pastrana Borrero (1970–1974) and the defeat of former dictator Gustavo Rojas Pinilla. Initially, the M-19 attracted a degree of attention and sympathy from mainstream Colombians that the FARC and National Liberation Army (ELN) had found largely elusive earlier due to extravagant and daring operations, such as stealing a sword that had belonged to Colombia's Independence hero Simon Bolívar. At the same time, its larger profile soon made it the focus of the state's counterinsurgency efforts.
The ELN guerrilla had been seriously crippled by military operations in the region of Anorí by 1974, but it managed to reconstitute itself and escape destruction, in part due to the administration of Alfonso López Michelsen (1974–1978) allowing it to escape encirclement, hoping to initiate a peace process with the group.
By 1982, the perceived passivity of the FARC, together with the relative success of the government's efforts against the M-19 and ELN, enabled the administration of the Liberal Party's Julio César Turbay (1978–1982) to lift a state-of-siege decree that had been in effect, on and off, for most of the previous 30 years. Under the latest such decree, president Turbay had implemented security policies that, though of some military value against the M-19 in particular, were considered highly questionable both inside and outside Colombian circles due to numerous accusations of military human rights abuses against suspects and captured guerrillas.
Citizen exhaustion due to the conflict's newfound intensity led to the election of president Belisario Betancur (1982–1986), a Conservative who won 47% of the popular vote, directed peace feelers at all the insurgents, and negotiated a 1984 cease-fire with the FARC and M-19 after a 1982 release of many guerrillas imprisoned during the previous effort to overpower them. The ELN rejected entering any negotiation and continued to recover itself through the use of extortions and threats, in particular against foreign oil companies of European and U.S. origin.
As these events were developing, the growing illegal drug trade and its consequences were also increasingly becoming a matter of widespread importance to all participants in the Colombian conflict. Guerrillas and newly wealthy drug lords had mutually uneven relations and thus numerous incidents occurred between them. Eventually, the kidnapping of drug cartel family members by guerrillas led to the creation of the 1981 Muerte a Secuestradores (MAS) death squad ("Death to Kidnappers"). Pressure from the U.S. government and critical sectors of Colombian society was met with further violence, as the Medellín Cartel and its hitmen, bribed or murdered numerous public officials, politicians and others who stood in its way by supporting the implementation of extradition of Colombian nationals to the U.S. Victims of cartel violence included Justice Minister Rodrigo Lara, whose assassination in 1984 made the Betancur administration begin to directly oppose the drug lords.
The first negotiated cease-fire with the M-19 ended when the guerrillas resumed fighting in 1985, claiming that the cease-fire had not been fully respected by official security forces, saying that several of its members had suffered threats and assaults, and also questioning the government's real willingness to implement any accords. The Betancur administration, in turn, questioned the M-19's actions and its commitment to the peace process, as it continued to advance high-profile negotiations with the FARC, which led to the creation of the Patriotic Union (Colombia) (UP), a legal and non-clandestine political organization.
On November 6, 1985, the M-19 stormed the Colombian Palace of Justice and held the Supreme Court magistrates hostage, intending to put president Betancur on trial. In the ensuing crossfire that followed the military's reaction, scores of people lost their lives, as did most of the guerrillas, including several high-ranking operatives. Both sides blamed each other for the outcome.
Meanwhile, individual FARC members initially joined the UP leadership in representation of the guerrilla command, though most of the guerrilla's chiefs and militiamen did not demobilize nor disarm, as that was not a requirement of the process at that point in time. Tension soon significantly increased, as both sides began to accuse each other of not respecting the cease-fire. Political violence against FARC and UP members (including presidential candidate Jaime Pardo) was blamed on drug lords and also on members of the security forces (to a much lesser degree on the argued inaction of Betancur administration). Members of the government and security authorities increasingly accused the FARC of continuing to recruit guerrillas, as well as kidnapping, extorting and politically intimidating voters even as the UP was already participating in politics.
The Virgilio Barco (1986–1990) administration, in addition to continuing to handle the difficulties of the complex negotiations with the guerrillas, also inherited a particularly chaotic confrontation against the drug lords, who were engaged in a campaign of terrorism and murder in response to government moves in favor of their extradition overseas. The UP also suffered an increasing number of losses during this term (including the assassination of presidential candidate Bernardo Jaramillo), which stemmed both from private proto-paramilitary organizations, increasingly powerful drug lords and a number of would-be paramilitary-sympathizers within the armed forces.
Following administrations had to contend with the guerrillas, paramilitaries, narcotics traffickers and the violence and corruption that they all perpetuated, both through force and negotiation. Narcoterrorists assassinated three presidential candidates before César Gaviria was elected in 1990. Since the death of Medellín cartel leader Pablo Escobar in a police shootout during December 1993, indiscriminate acts of violence associated with that organization have abated as the "cartels" have broken up into multiple, smaller and often-competing trafficking organizations. Nevertheless, violence continues as these drug organizations resort to violence as part of their operations but also to protest government policies, including extradition.
The M-19 and several smaller guerrilla groups were successfully incorporated into a peace process as the 1980s ended and the 1990s began, which culminated in the elections for a Constituent Assembly of Colombia that would write a new constitution, which took effect in 1991. The new Constitution, brought about a considerable number of institutional and legal reforms based on principles that the delegates considered as more modern, humanist, democratic and politically open than those in the 1886 constitution. Practical results were mixed and mingled emerged (such as the debate surrounding the constitutional prohibition of extradition, which later was reversed), but together with the reincorporation of some of the guerrilla groups to the legal political framework, the new Constitution inaugurated an era that was both a continuation and a gradual, but significant, departure from what had come before.
Contacts with the FARC, which had irregularly continued despite the generalized de facto interruptions of the ceasefire and the official 1987 break from negotiations, were temporarily cut off in 1990 under the presidency of César Gaviria (1990–1994). The Colombian Army's assault on the FARC's Casa Verde sanctuary at La Uribe, Meta, followed by a FARC offensive that sought to undermine the deliberations of the Constitutional Assembly, began to highlight a significant break in the uneven negotiations carried over from the previous decade.
President Ernesto Samper assumed office in August 1994. However, a political crisis relating to large-scale contributions from drug traffickers to Samper's presidential campaign diverted attention from governance programs, thus slowing, and in many cases, halting progress on the nation's domestic reform agenda. The military also suffered several setbacks in its fight against the guerrillas, when several of its rural bases began to be overrun and a record number of soldiers and officers were taken prisoner by the FARC (which since 1982 was attempting to implement a more "conventional" style of warfare, seeking to eventually defeat the military in the field).
On August 7, 1998, Andrés Pastrana was sworn in as the President of Colombia. A member of the Conservative Party, Pastrana defeated Liberal Party candidate Horacio Serpa in a run-off election marked by high voter turnout and little political unrest. The new president's program was based on a commitment to bring about a peaceful resolution of Colombia's longstanding civil conflict and to cooperate fully with the United States to combat the trafficking of illegal drugs.
While early initiatives in the Colombian peace process gave reason for optimism, the Pastrana administration also has had to combat high unemployment and other economic problems, such as the fiscal deficit and the impact of global financial instability on Colombia. During his administration, unemployment has risen to over 20%. Additionally, the growing severity of countrywide guerrilla attacks by the FARC and ELN, and smaller movements, as well as the growth of drug production, corruption and the spread of even more violent paramilitary groups such as the United Self-Defense Forces of Colombia (AUC) has made it difficult to solve the country's problems.
Although the FARC and ELN accepted participation in the peace process, they did not make explicit commitments to end the conflict. The FARC suspended talks in November 2000, to protest what it called "paramilitary terrorism" but returned to the negotiating table in February 2001, following 2 days of meetings between President Pastrana and FARC leader Manuel Marulanda. The Colombian Government and ELN in early 2001 continued discussions aimed at opening a formal peace process.
By 2004, the security situation of Colombia had shown some measure of an improvement, and the economy, while still fragile, had also shown some positive signs. On the other hand, relatively little had been accomplished in structurally solving most of the country's other grave problems, in part due to legislative and political conflicts between the administration and the Colombian Congress (including those over the controversial 2006 project to give President Álvaro Uribe the right to be re-elected), and a relative lack of freely allocated funds and credits. In October 2006, Uribe was re-elected by a landslide.
Some critical observers consider in retrospect that Uribe's policies, while admittedly reducing crime and guerrilla activity, were too slanted in favor of a military solution to Colombia's internal war, neglecting grave social and human rights concerns to a certain extent. They hoped that Uribe's government would make serious efforts towards improving the human rights situation inside the country, protecting civilians and reducing any abuses committed by the armed forces.
Uribe's supporters in turn believed that increased military action was a necessary prelude to any serious negotiation attempt with the guerrillas and that the increased security situation would help the government, in the long term, to focus more actively on reducing most wide-scale abuses and human rights violations on the part of both the armed groups and any rogue security forces that might have links to the paramilitaries. In short, these supporters maintained that the security situation needed to be stabilized in favor of the government before any other social concerns could take precedence. In February 2010, the constitutional court blocked President Alvaro Uribe from seeking for a new re-election. Uribe left the presidency in 2010.
In 2010 Juan Manuel Santos was elected president; he was supported by ex-president Uribe, and, in fact, he owed his election mainly through having won over former Uribe supporters. But two years after winning the presidential election, Santos (to widespread surprise) began peace talks with FARC, which took place in Havana. Re-elected in 2014, Santos revived an important infrastructure program, which in fact had been planned during the Uribe administration. Focused mainly on the provision of national highways, the program was led by former vice-president Germán Vargas Lleras.
In 2015, Colombia's Congress limited presidency to single term, preventing the president from seeking re-election.
Talks between the government and the guerrillas resulted in the announcement of a peace agreement. However, a referendum to ratify the deal was unsuccessful. Afterward, the Colombian government and the FARC signed a revised peace deal in November 2016, which the Colombian congress approved. In 2016, President Santos was awarded the Nobel Peace Prize. The Government began a process of attention and comprehensive reparation for victims of conflict. Colombia under President Santos showed some progress in the struggle to defend human rights, as expressed by HRW. A Special Jurisdiction of Peace was created to investigate, clarify, prosecute and punish serious human rights violations and grave breaches of international humanitarian law which occurred during the armed conflict and to satisfy victims' right to justice. During his visit to Colombia, Pope Francis paid tribute to the victims of the conflict.
In May 2018, Ivan Duque, the candidate of the conservative Centro Democrático (Democratic Centre), won the presidential election. On 7 August 2018, he was sworn in as the new President of Colombia.
Colombia's relations with Venezuela have fluctuated due to the ideological differences between both governments. Colombia has offered humanitarian support with food and medicines to mitigate the shortage of supplies in Venezuela. Colombia's Foreign Ministry said that all efforts to resolve Venezuela's crisis should be peaceful. Colombia proposed the idea of the Sustainable Development Goals and a final document was adopted by the United Nations. In February 2019, Venezuelan president Nicolás Maduro cut diplomatic relations with Colombia after Colombian President Ivan Duque helped Venezuelan opposition politicians deliver humanitarian aid to their country. Colombia recognized Venezuelan opposition leader Juan Guaido as the country's legitimate president. In January 2020, Colombia rejected Maduro's proposal that the two countries restore diplomatic relations.
The 19 June 2022 election run-off vote ended in a win for former guerrilla, Gustavo Petro, taking 50.47% of the vote compared to 47.27% of right-wing Rodolfo Hernández. The single-term limit for the country's presidency prevented president Iván Duque from seeking re-election. Petro became the country’s first leftist president-elect. On 7 August 2022, he was sworn in. | [

At Puerto Hormiga archaeological site and other sites, traces from the Archaic period in South America (~8000–2000 BCE) have been found. Vestiges indicate that there was also early occupation in the regions of El Abra, Tibitó and Tequendama in Cundinamarca. The oldest pottery discovered in the Americas, found at San Jacinto archaeological site, dates to 5000–4000 BCE. Indigenous people inhabited the territory that is now Colombia by 10,500 BCE.

Illegal trade between Peruvians, Filipinos, and Mexicans continued in secret, as smuggled Asian goods ended up in Córdoba, Colombia, the distribution center for illegal Asian imports, due to the collusion between these peoples against the authorities in Spain. They settled and traded with each other while disobeying the forced Spanish monopoly in more expensive silks and porcelain made in homeland Spain.

Under the latest such decree, president Turbay had implemented security policies that, though of some military value against the M-19 in particular, were considered highly questionable both inside and outside Colombian circles due to numerous accusations of military human rights abuses against suspects and captured guerrillas.",

Guerrillas and newly wealthy drug lords had mutually uneven relations and thus numerous incidents occurred between them. Eventually, the kidnapping of drug cartel family members by guerrillas led to the creation of the 1981 Muerte a Secuestradores (MAS) death squad (\"Death to Kidnappers\"). Pressure from the U.S. government and critical sectors of Colombian society was met with further violence, as the Medellín Cartel and its hitmen, bribed or murdered numerous public officials, politicians and others who stood in its way by supporting the implementation of extradition of Colombian nationals to the U.S. Victims of cartel violence included Justice Minister Rodrigo Lara, whose assassination in 1984 made the Betancur administration begin to directly oppose the drug lords.",

The Betancur administration, in turn, questioned the M-19's actions and its commitment to the peace process, as it continued to advance high-profile negotiations with the FARC, which led to the creation of the Patriotic Union (Colombia) (UP), a legal and non-clandestine political organization.",

The new Constitution, brought about a considerable number of institutional and legal reforms based on principles that the delegates considered as more modern, humanist, democratic and politically open than those in the 1886 constitution.

] | The history of Colombia includes the settlements and society by indigenous peoples, most notably, the Muisca Confederation, Quimbaya Civilization, and Tairona Chiefdoms; the Spanish arrived in 1492 and initiated a period of annexation and colonization, most noteworthy being Spanish conquest; ultimately creating the Viceroyalty of New Granada, with its capital at Bogotá. Independence from Spain was won in 1819, but by 1830 the "Gran Colombia" Federation was dissolved. What is now Colombia and Panama emerged as the Republic of New Granada. The new nation experimented with federalism as the Granadine Confederation (1858), and then the United States of Colombia (1863), before the Republic of Colombia was finally declared in 1886; as well as constant political violence in the country. Panama seceded in 1903. Since the 1960s, the country has suffered from an asymmetric low-intensity armed conflict, which escalated in the 1990s, but then decreased from 2005 onward. The legacy of Colombia's history has resulted in a rich cultural heritage; while varied geography, and the imposing landscape of the country has resulted in the development of very strong regional identities. | 2001-07-20T18:56:15Z | 2023-12-31T20:40:33Z | [

5,845 | Foreign relations of Colombia | Colombia seeks diplomatic and commercial relations with all countries, regardless of their ideologies or political or economic systems. For this reason, the Colombian economy is quite open, relying on international trade and following guidelines given by international law.
Since 2008, Colombia's Ministry of Trade and Commerce has either reached or strengthened Bilateral Trade Agreements with South Korea, Japan and China building stronger commerce interchange and development in the Pacific Rim.
Regional relations have also vastly improved under the Santos Administration (2010–2018). Issues however remain regarding spillover of the FARC leftist-terrorist group, being chased out of hiding in rural areas of Colombia and finding safe havens in non-monitored areas of bordering states. The FARC numbers have significantly diminished in the last decade, to an estimated 5,000–7,000. And while joint military collaboration has steadily increased with the bordering countries of Brazil, Panama, Peru, and Venezuela, there have been tensions between Colombia and Ecuador regarding the issue. In 2002, the Ecuadorian government closed its main border crossing with Colombia, restricting its hours of operation. Ecuador continues to voice its concerns over an influx of émigrés stemming from guerilla activity at its borders. Evidence has since emerged however, suggesting that a significant number of the FARC's foot soldiers in and around the Colombia–Ecuador border consist of Ecuadorian émigrés who joined the leftist terrorist group out of need. Returning Ecuadorian émigrés have faced re-entry restrictions.
In 2012, relations with Nicaragua and Venezuela were tested over territorial island disputes. Bilateral committees are negotiating the dispute with Venezuela over waters in the Gulf of Venezuela.
In 1969, Colombia formed what is now the Andean Community along with Bolivia, Chile, Ecuador, and Peru (Venezuela joined in 1973, and Chile left in 1976).
In the 1980s, Colombia broadened its bilateral and multilateral relations, joining the Contadora Group, the Group of Eight (now the Rio Group), and the Non-Aligned Movement, which it chaired from 1994 until September 1998. In addition, it has signed free trade agreements with Chile, Mexico, and Venezuela.
Colombia has traditionally played an active role in the United Nations and the Organization of American States and in their subsidiary agencies. Former President César Gaviria became Secretary General of the OAS in September 1994 and was reelected in 1999. Colombia was a participant in the December 1994 and April 1998 Summits of the Americas and followed up on initiatives developed at the summit by hosting two post-summit, ministerial-level meetings on trade and science and technology.
Colombia regularly participates in international fora, including CICAD, the Organization of American States' body on money laundering, chemical controls, and drug abuse prevention. Although the Colombian Government ratified the 1988 UN Convention on Narcotics in 1994—the last of the Andean governments to do so—it took important reservations, notably to the anti-money-laundering measures, asset forfeiture and confiscation provisions, maritime interdiction, and extradition clauses. Colombia subsequently withdrew some of its reservations, most notably a reservation on extradition.
Maritime boundary dispute with Venezuela in the Gulf of Venezuela; territorial disputes with Nicaragua over Archipelago de San Andrés y Providencia and Quita Sueño Bank. The United States disputes sovereignty with Colombia over the Serranilla Bank and the Bajo Nuevo Bank. Quita Sueño Bank is claimed by the United States to be a submerged reef, and thus does not recognize the sovereignty of any nation over the bank.
The major organizations in which Colombia is a member include: the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean, Andean Pact, Caribbean Development Bank Economic Commission for Latin America and the Caribbean, Food and Agriculture Organization of the United Nations, Group of 3, Group of 11, Group of 24, Group of 77, Inter-American Development Bank, International Atomic Energy Agency, International Bank for Reconstruction and Development, International Chamber of Commerce, International Civil Aviation Organization, International Criminal Police Organization (Interpol), International Development Association, International Finance Corporation, International Fund for Agricultural Development, International Labour Organization, International Maritime Organization, International Maritime Satellite Organization, International Monetary Fund (IMF), International Olympic Committee, International Organization for Migration, International Organization for Standardization, International Telecommunication Union, International Telecommunications Satellite Organization, International Trade Union Confederation, Latin American Economic System, Latin American Integration Association, Non-Aligned Movement, Organization of American States (OAS), Permanent Court of Arbitration, Rio Group, United Nations (UN), UN Conference on Trade and Development, UNESCO, UN Industrial Development Organization, UN Office of the High Commissioner for Refugees, Universal Postal Union, World Confederation of Labour, World Federation of Trade Unions, World Health Organization, World Intellectual Property Organization, World Meteorological Organization, World Tourism Organization, and World Trade Organization. An OAS observer has monitored the government's peace process with the paramilitaries, lending the negotiations much-needed international credibility. The United States helps Colombia secure favorable treatment from the IMF.
Regional treaties include the Andean Pact, now known as the Andean Community, which also includes Bolivia, Ecuador, and Peru, the bodies and institutions making up the Andean Integration System (AIS). Colombia has signed free-trade agreements with Chile, Mexico, and Venezuela.
Its recent trade agreements with Korea, China and Japan, have focused on economic and technical cooperation between those nations. Within the regional Caribbean Community and Common Market (Caricom), Colombia has also deepened economic and medical science research collaboration agreements. Colombia has also signed and ratified 105 international treaties or agreements relating to the protection of the environment. These include the Antarctic Treaty and Nuclear Test Ban Treaty and conventions on Biodiversity, Desertification, Endangered Species, Hazardous Wastes, Marine Life Conservation, Ozone Layer Protection, Ship Pollution, Tropical Timber 83, Tropical Timber 94, and Wetlands. It has signed, but not ratified, the Antarctic-Environmental Protocol and conventions on Law of the Sea and Marine Dumping. Colombia also has signed the Treaty on the Non-Proliferation of Nuclear Weapons and the Tlatelolco Treaty. By 1975 signatories to the 1974 Declaration of Ayacucho, of which Colombia was one, had decided on limitations to nuclear, biological, and chemical weapons.
Gaining all 186 votes, Colombia served on the U.N. Security Council from 2011 to 2012 representing Latin American and the Caribbean.
Colombia is also a member of the International Criminal Court with a Bilateral Immunity Agreement of protection for the United States-military (as covered under Article 98).
International Relations scholars long emphasized international constraints, and particularly Colombia's relationship with the United States, as central to its foreign policy. In terms of foreign policy process, presidents have broad constitutional authorities, in consultation with their foreign ministers. However, since the 2000s, the influence of other domestic actors in Colombian foreign policy-making has increased. Long, Bitar, and Jiménez-Peña examine the role of the Colombian Constitutional Court, congressional politics, social movements, and electoral challengers. They find that Colombian institutions permit increasing challenges to presidential authority, and that in important cases Colombian presidents have been forced to drop their preferred foreign policies.
List of countries which Colombia maintains diplomatic relations with:
Under the Uribe administration, Colombia's relations with the European Union (EU) have been cordial. Representatives of the EU have been critical of Colombia's antiguerrilla and antidrug strategies in several respects. The EU is particularly concerned about the potential for increased human rights abuses within Colombia at the hands of both government forces and illegal armed groups, and it has continued to distance itself from Plan Colombia. The EU is in favor of a negotiated solution to the nation's internal conflict. EU aid to Colombia has mainly consisted of social, economic and development investments.
In 2004, the EU as an entity did not offer unrestricted support for the Uribe government's peace initiative with paramilitaries, citing concerns over the possible lack of a credible and comprehensive peace strategy and its application, but it did approve US$2 million in aid for the process. Individual EU members such Sweden, Italy, Germany and the Netherlands also provided limited support on their own.
By the 1990s, Colombia had become the world's leading supplier of refined cocaine and a growing source for heroin. More than 90% of the cocaine that entered in the 1990s the United States was produced, processed, or transshipped in Colombia. The cultivation of coca dropped between 1995 and 1999 from 3,020 to 1,100 km (425 sq mi), primarily in areas where government control was more active.
Despite the death of Medellín cartel drug kingpin Pablo Escobar in 1993 and the arrests of major Cali cartel leaders in 1995 and 1996, Colombian drug cartels remain among the most sophisticated criminal organizations in the world, controlling cocaine processing, international wholesale distribution chains, and markets. In 1999 Colombian police arrested over 30 narcotraffickers, most of them extraditable, in "Operation Millennium" involving extensive international cooperation. More arrests were made in a following "Operation Millennium II."
Colombia is engaged in a broad range of narcotics control activities. Through aerial spraying of herbicide and manual eradication, Colombia has attempted to keep coca, opium poppy, and cannabis cultivation from expanding. The government has committed itself to the eradication of all illicit crops, interdiction of drug shipments, and financial controls to prevent money laundering. Alternative development programs were introduced in 1999.
Corruption and intimidation by traffickers complicate the drug-control efforts of the institutions of government. Colombia passed revised criminal procedures code in 1993 that permits traffickers to surrender and negotiate lenient sentences in return for cooperating with prosecutors. In December 1996 and February 1997, however, the Colombian Congress passed legislation to toughen sentencing, asset forfeiture, and money-laundering penalties.
In November 1997, the Colombian Congress amended the constitution to permit the extradition of Colombian nationals, albeit not retroactively. In late 1999, President Pastrana authorized the first extradition in almost 10 years of a Colombian trafficker to stand trial for U.S. crimes. Three such extraditions to the United States have taken place, the most recent in August 2000, with cases against others pending in Colombian courts. Under the Pastrana administration, Plan Colombia was developed and implemented with U.S. backing.
During the presidency of Álvaro Uribe, the government applied more military pressure on the FARC and other outlawed groups. After the offensive, many security indicators improved. Colombia achieved a great decrease in cocaine production, leading White House drug czar R. Gil Kerlikowske to announce that Colombia is no longer the world's biggest producer of cocaine.
In addition to the challenge posed to the United States by Colombian drug trafficking, illegal Colombian immigrants in the United States are an issue in Colombia-U.S. relations. According to figures from the U.S. Department of Homeland Security, Colombia is the fourth-leading source country of illegal immigration to the United States. According to its estimates, the number of illegal Colombian residents in the United States almost tripled from 51,000 in 1990 to 141,000 in 2000. According to the US Census Bureau, the number of authorized Colombian immigrants in the United States in 2006 was 801,363.
Colombia rejected threats and blackmail of the United States of America after the threat of Donald Trump to decertify the country as a partner in counter-narcotics efforts.
For more than 30 years Colombia has demonstrated its commitment – paying a very high cost in human lives – with overcoming the drug problem. This commitment stems from the profound conviction that the consumption, production and trafficking of drugs constitute a serious threat to the well-being and security of citizens. Colombia is undoubtedly the country that has fought the most drugs and with more successes on this front. No one has to threaten us to meet this challenge.
The problem of drugs is global. Overcoming it can only be achieved through cooperation and under the principle of joint responsibility. Consumer countries’ authorities have a fundamental responsibility to their fellow citizens and the world to reduce consumption and to attack trafficking and distribution organizations in their own countries. | [

] | Colombia seeks diplomatic and commercial relations with all countries, regardless of their ideologies or political or economic systems. For this reason, the Colombian economy is quite open, relying on international trade and following guidelines given by international law. Since 2008, Colombia's Ministry of Trade and Commerce has either reached or strengthened Bilateral Trade Agreements with South Korea, Japan and China building stronger commerce interchange and development in the Pacific Rim. Regional relations have also vastly improved under the Santos Administration (2010–2018). Issues however remain regarding spillover of the FARC leftist-terrorist group, being chased out of hiding in rural areas of Colombia and finding safe havens in non-monitored areas of bordering states. The FARC numbers have significantly diminished in the last decade, to an estimated 5,000–7,000. And while joint military collaboration has steadily increased with the bordering countries of Brazil, Panama, Peru, and Venezuela, there have been tensions between Colombia and Ecuador regarding the issue. In 2002, the Ecuadorian government closed its main border crossing with Colombia, restricting its hours of operation. Ecuador continues to voice its concerns over an influx of émigrés stemming from guerilla activity at its borders. Evidence has since emerged however, suggesting that a significant number of the FARC's foot soldiers in and around the Colombia–Ecuador border consist of Ecuadorian émigrés who joined the leftist terrorist group out of need. Returning Ecuadorian émigrés have faced re-entry restrictions. In 2012, relations with Nicaragua and Venezuela were tested over territorial island disputes. Bilateral committees are negotiating the dispute with Venezuela over waters in the Gulf of Venezuela. | 2002-02-25T15:51:15Z | 2023-12-15T09:24:06Z | [

5,846 | Geography of the Czech Republic | The Czech Republic is a landlocked country in Central Europe. It is bordered by Germany to the west, Austria to the south, Slovakia to the east and Poland to the north. It consists mostly of low hills and plateaus surrounded along the borders by low mountains. Two areas of lowlands follow the Elbe river and the Morava river. About a third of the area of the Czech Republic is covered by forests.
The Czech Republic also possesses Moldauhafen, a 30,000 m enclave in the middle of Hamburg docks in Germany, which was awarded to Czechoslovakia by Article 363 of the Treaty of Versailles to allow the landlocked country a place where goods transported down river could be transferred to seagoing ships. This territory reverts to Germany in 2028.
The Czech Republic's climate is temperate, transitional between an oceanic climate and a continental climate. The summers are rather cool and dry, with average temperatures in most areas around 20 °C, the winters are fairly mild and wet with temperatures averaging around 0 °C in most areas. The relative humidity varies between 60% and 80%.
Most of the area of the Czech Republic belongs to the geographically stable Bohemian Massif. Only an area of the Western Carpathians in the east of the country is younger, lifted during the Tertiary. Igneous rocks make up the base of the Bohemian Massif. Sedimentary rocks are mostly found in the north-eastern part of Bohemia with significant areas of sandstone. Among the metamorphic rocks, the most commonly found is Gneiss.
The most notable mountain ranges in the Czech Republic are all found along the borders of the country. In Bohemia it is the Bohemian Forest and Ore Mountains, both bordering Germany. Then the long region of Sudetes with several mountains ranges, including Giant Mountains with Sněžka – the highest peak of the Czech Republic. The last major mountain range is the Moravian-Silesian Beskids in the east.
There are four major rivers in the Czech Republic. The Elbe (locally "Labe") flows from the Giant Mountains in the north east of Bohemia to the west and then through northern Germany all the way to the North Sea. The Morava River drains most of Moravia and flows to the south into the Danube and ultimately to the Black Sea. The Oder starts in the Moravian Silesia and flows north through Poland into the Baltic Sea. The fourth major river is the Vltava, which is the longest river of the Czech Republic and drains the southern part of Bohemia before flowing into the Elbe at Mělník.
Natural occurring bodies of water are rather scarce; most of the significant bodies of water are man-made ponds and reservoirs. The largest pond is the Rožmberk Pond, which is one of the system of fish ponds built in the 16th century around Třeboň. The largest reservoir by area covered is the Lipno Reservoir (4,870 ha), built in the 1950s and the largest reservoir by volume is Orlík Reservoir (716 million m), built around the same time. The largest and deepest natural lake is Černé jezero (18.4 ha).
The population of the Czech Republic is estimated to be around 10.6 million. The highest population density is in the larger metropolitan area of Ostrava and of course in the area around the capital of Prague. The lowest population density is in the Czech-German and Czech-Austrian borderlands, mostly as a lasting result of the expulsion of Germans from Czechoslovakia after the World War II.
The Czech Republic is divided into thirteen regions and one capital city with regional status. The older administrative units of seventy-six districts are still recognized and remain the seats of various branches of state administration. Historically, the Czech Republic can be split into three regions: Bohemia in the west, Moravia in the east and Czech Silesia in the north east.
Areas affected the most by heavy industry are the Sokolov Basin and the Most Basin in the north-west of the Czech Republic. The extensive deposits of brown coal in those areas are mostly used for electricity production. It is estimated, that almost 40% of all electric power produced in the Czech Republic comes from burning brown coal mined in these areas. Plant agriculture is focused around the lowlands surrounding the Elbe and the Morava. Around 34% of the country is covered by forests and approximately 37% of land is arable. The estimated area of irrigated land is 385 km, and freshwater withdrawal per capita is around 164 m every year.

5,848 | Politics of the Czech Republic | The Czech Republic is a unitary parliamentary republic, in which the president is the head of state and the prime minister is the head of government. Executive power is exercised by the Government of the Czech Republic, which reports to the Chamber of Deputies. The legislature is exercised by the Parliament. The Czech Parliament is bicameral: the upper house of the Parliament is the Senate, and the lower house is the Chamber of Deputies. The Senate consists of 81 members who are elected for six years. The Chamber of Deputies consists of 200 members who are elected for four years. The judiciary system is topped by the trio of the Constitutional Court, Supreme Court and Supreme Administrative Court.
The highest legal document is the Constitution of the Czech Republic, complemented by constitutional laws and the Charter of Fundamental Rights and Freedoms. The current constitution went in effect on 1 January 1993, after the dissolution of Czechoslovakia.
The Czech Republic has a multi-party system. Between 1993 and 2013, the two largest political parties were the centre-left Czech Social Democratic Party (ČSSD) and centre-right Civic Democratic Party (ODS). This changed in early 2014, with the rise of a new major political party ANO 2011, which has since led two cabinets.
The Economist Intelligence Unit rated Czech Republic a "flawed democracy" in 2022.
The president is the head of state, and the prime minister is the head of government. The majority of executive power is given to the Cabinet, which consists of the prime minister, deputy prime ministers and ministers (usually heads of the ministries).
The president of the Czech Republic is elected by a direct vote for five years. They can only serve for two terms. The president is a formal head of state with limited executive powers specified in the articles 54 to 66 of the Constitution:
The president is also the commander in chief of the Armed Forces and ratifies all domestic laws and international agreements.
The Cabinet is the supreme executive body in the Czech Republic. It makes its decisions as a body. It is held responsible by the Chamber of Deputies. The president appoints every new prime minister, who then chooses the ministers. All ministers of the Cabinet need to be approved by the president and within thirty days after the presidential approval they must ask the Chamber of Deputies for a vote of confidence.
The prime minister is the head of government. The prime minister organizes the work of the Cabinet, presides over it and acts in its name. The prime minister sets the agenda for most foreign and domestic policies but has to obtain the president's approval to hire or dismiss any other member of the Cabinet.
Ministers are any member of the Cabinet who are not the prime minister. They are usually the head of a ministry, but this is not required. A ministry – sometimes called government department – is a governmental organisation that manages a specific sector of public administration. The number of ministries varies depending on the particular Cabinet and is managed by the Competence Law. As of 2021, the Czech Republic had 13 ministers and 14 ministries.
The Parliament (Parlament in Czech) consists of two houses. The lower house is the Chamber of Deputies, and the upper house is the Senate.
The Chamber of Deputies (Poslanecká sněmovna in Czech) has 200 members, elected for four-year terms by proportional representation with a 5% election threshold. The Chamber of Deputies elections happen every four years, unless the reigning Cabinet prematurely loses the Chamber of Deputies' support. Candidates for every political party participating in the elections are split among 14 electoral districts, which are identical to the country's administrative regions. A citizen must be at least 21 years old to be eligible for candidacy.
The Chamber of Deputies was formerly known as the Czech National Council. It has the same powers and responsibilities as the now-defunct Federal Assembly of the Czechoslovakia.
The Senate (Senát in Czech) has 81 members, each elected for a six-year term. Senate elections happen every two years and only a third of the seats is contested each time. All of the 81 Senate electoral districts are designed to contain roughly the same number of voters. The Senate elections use a two-round system, when the two most successful candidates from the first round face each other again in the second round usually a week later. Only citizens who have reached the age of 40 are eligible for candidacy. The senate's function is to be a stabilizing force and its influence is significantly lower than that of the Chamber of Deputies.
The Czech court system recognizes four categories of courts and the Constitutional Court, which stands outside of the court system.
The Constitutional Court's main purpose is to protect people's constitutional rights and freedoms. The decisions of the court are final, cannot be overturned and are considered a source of law. The court is composed of 15 justices who are named for a renewable period of 10 years by the president and approved by the Senate. Its functionality is similar to that of the Supreme Court of the United States.
There are two supreme courts in the court system of the Czech Republic – the Supreme Court and the Supreme Administrative Court. Both reside in Brno.
The Supreme Court of the Czech Republic is the court of highest appeal for almost all legal cases heard in the Czech Republic. The justices of the Supreme Court analyze and evaluate legally effective decisions of lower courts. They unify the Czech judicature.
The Supreme Administrative Court of the Czech Republic protects people from unlawful decisions and procedures of the state authorities. It examines objections to elections and has the authority to ban or suspend the activity of political parties. It resolves competence disputes between governmental organizations and also serves as disciplinary court for other members of the judiciary.
There are two high courts in the Czech Republic – one in Prague and one in Olomouc . They serve as courts of appeal to Regional Courts in cases, where the Regional Court acted as a court of first instance. Presidents of the high courts are appointed by the president for seven years. The vice-presidents are appointed by the minister of justice and also serve a seven-year term. A justice is required by the law to have at least eight years of experience before becoming a member of a High Court.
Regional courts serve mainly as the courts of appeal to district courts. However, they can also act as courts of first instance in cases of more severe criminal charges, disputes between corporations or disputes over intellectual property. There are eight regional courts in the Czech Republic: in Brno, Ostrava, Hradec Králové, Ústí nad Labem, Plzeň, České Budějovice and two in Prague.
District courts serve as the courts of first instance in almost all civil or criminal proceedings. There is a total of 86 district courts in the Czech Republic. Notaries and executors are appointed by the minister of justice to their jurisdictions.
The Czech Republic is divided in 14 administrative regions, including one for the capital of Prague. The older system of 73 administrative districts (okresy in Czech) and 4 municipalities was abandoned in 1999 in an administrative reform. Each of the regions has a regional council with a varied number of regional councilors and a president of the regional cabinet (hejtman in Czech) as its formal head. The capital of Prague is the only exception to this, as the City Council acts both as regional and municipal governing body and is led by a mayor. Regional councilors are elected for four-year terms similarly to deputies in the Chamber of Deputies. All adults eligible to vote are also eligible to candidate to a regional council.
For the current composition of the Chamber of Deputies of the Czech Republic, see List of MPs elected in the 2017 Czech legislative election.
From 1991, the Czech Republic, originally as part of Czechoslovakia and since 1993 in its own right, has been a member of the Visegrád Group and from 1995, the OECD. The Czech Republic joined NATO on 12 March 1999 and the European Union on 1 May 2004. On 21 December 2007 the Czech Republic joined the Schengen Area.
Until 2017, either the Czech Social Democratic Party or the Civic Democratic Party led the governments of the Czech Republic. In October 2017, populist movement ANO 2011, led by the country's second-richest man, Andrej Babiš, won the elections with three times more votes than its closest rival, the centre-right Civic Democrats. In December 2017, Czech President Miloš Zeman appointed Andrej Babiš as the new prime minister.
On 28 November 2021, Czech President Miloš Zeman appointed opposition leader Petr Fiala as the country's new prime minister. The centre-right coalition Spolu (meaning Together) won tightly contested legislative elections in October 2021 against Prime Minister Andrej Babiš and his populist ANO party. Babiš had sought re-election after four years in power. In January 2023, Former NATO general Petr Pavel won the election runoff over Andrej Babis to succeed Miloš Zeman as the fourth president of the Czech Republic.

5,849 | Economy of the Czech Republic | The economy of the Czech Republic is a developed export-oriented social market economy based in services, manufacturing, and innovation that maintains a high-income welfare state and the European social model. The Czech Republic participates in the European Single Market as a member of the European Union, and is therefore a part of the economy of the European Union. It uses its own currency, the Czech koruna, instead of the euro. It is a member of the Organisation for Economic Co-operation and Development (OECD). The Czech Republic ranks 16th in inequality-adjusted human development and 24th in World Bank Human Capital Index, ahead of countries such as the United States, the United Kingdom or France. It was described by The Guardian as "one of Europe's most flourishing economies".
The industry sector accounts for 37% of the economy, while services account for 61% and agriculture for 2%. The principal industries are high tech engineering, electronics and machine-building, steel production, transportation equipment (automotive, rail and aerospace industry), chemicals, advanced materials and pharmaceuticals. The major services are research and development, ICT and software development, nanotechnology and life sciences. Its main agricultural products are cereals, vegetable oils and hops.
As of 2023, the Czech GDP per capita at purchasing power parity is $50,961 and 698,706 Czech crowns ($31,368) at nominal value. As of September 2021, the unemployment rate in the Czech Republic was the lowest in the EU at 2.6%, and the poverty rate is the second lowest of OECD members, following Denmark. The Czech Republic ranks 21st in the Index of Economic Freedom (ranked behind Chile), 30th in the Global Innovation Index (ranked behind UAE), 32nd in the Global Competitiveness Report, 41st in the ease of doing business index and 25th in the Global Enabling Trade Report (ranked behind Canada). The largest trading partner for both export and import is Germany, followed by other members of the EU. The Czech Republic has a highly diverse economy that ranks 7th in the 2019 Economic Complexity Index.
The Czech lands were among the first industrialized countries in continental Europe during the German Confederation era. The Czech industrial tradition dates back to the 19th century, when the Lands of the Bohemian Crown were the economic and industrial heartland of the Austrian Empire and later the Austrian side of Austria-Hungary. The Czech lands produced a majority (about 70%) of all industrial goods in the Empire, some of which were almost monopolistic. The Czechoslovak crown was introduced in April 1919. Introduced at a 1:1 ratio to the Austro-Hungarian currency, it became one of the most stable currencies in Europe. The First Republic became one of the 10 most developed countries of the world (behind the U.S., Canada, Australia, Switzerland, Argentina, Britain, France, Sweden and Belgium).
The consequences of the 1938 Munich Agreement and subsequent occupation were disastrous for the economy. After the occupation and forced subordination of the economy to German economic interests, the crown was officially pegged to the mark at a ratio of 1:10, even though the unofficial exchange rate was 1 to 6-7 and Germans immediately started buying Czech goods in large quantities.
In accordance with Stalin's development policy of planned interdependence, all the economies of the socialist countries were tightly linked to that of the Soviet Union. Czechoslovakia was the most prosperous country in the Eastern Bloc, however it continued to lag further behind the rest of the developed world. With the disintegration of the communist economic alliance in 1991, Czech manufacturers lost their traditional markets among former communist countries in the east.
Today, this heritage is both an asset and a liability. The Czech Republic has a well-educated population and a densely developed infrastructure.
The "Velvet Revolution" in 1989, offered a chance for profound and sustained political and economic reform. Signs of economic resurgence began to appear in the wake of the shock therapy that the International Monetary Fund (IMF) labelled the "big bang" of January 1991. Since then, consistent liberalization and astute economic management has led to the removal of 95% of all price controls, low unemployment, a positive balance of payments position, a stable exchange rate, a shift of exports from former communist economic bloc markets to Western Europe, and relatively low foreign debt. Inflation has been higher than in some other countries – mostly in the 10% range – and the government has run consistent modest budget deficits.
Two government priorities have been strict fiscal policies and creating a good climate for incoming investment in the republic. Following a series of currency devaluations, the crown has remained stable in relation to the US dollar. The Czech crown became fully convertible for most business purposes in late 1995.
In order to stimulate the economy and attract foreign partners, the government has revamped the legal and administrative structure governing investment. With the breakup of the Soviet Union, the country, till that point highly dependent on exports to the USSR, had to make a radical shift in economic outlook: away from the East, and towards the West. This necessitated the restructuring of existing banking and telecommunications facilities, as well as adjusting commercial laws and practices to fit Western standards. Further minimizing reliance on a single major partner, successive Czech governments have welcomed U.S. investment (amongst others) as a counterbalance to the strong economic influence of Western European partners, especially of their powerful neighbour, Germany. Although foreign direct investment (FDI) runs in uneven cycles, with a 12.9% share of total FDI between 1990 and March 1998, the U.S. was the third-largest foreign investor in the Czech economy, behind Germany and the Netherlands.
Progress toward creating a stable investment climate was recognized when the Czech Republic became the first post-communist country to receive an investment-grade credit rating by international credit institutions.
The country boasts a flourishing consumer production sector and has privatized most state-owned heavy industries through the voucher privatization system. Under the system, every citizen was given the opportunity to buy, for a moderate price, a book of vouchers that represents potential shares in any state-owned company. The voucher holders could then invest their vouchers, increasing the capital base of the chosen company, and creating a nation of citizen share-holders. This is in contrast to Russian privatization, which consisted of sales of communal assets to private companies rather than share-transfer to citizens. The effect of this policy has been dramatic. Under communism, state ownership of businesses was estimated to be 97%. Privatization through restitution of real estate to the former owners was largely completed in 1992. By 1998, more than 80% of enterprises were in private hands. Now completed, the program has made Czechs, who own shares of each of the Czech companies, one of the highest per-capita share owners in the world.
The country's economic transformation was far from complete. Political and financial crises in 1997 shattered the Czech Republic's image as one of the most stable and prosperous of post-Communist states. Delays in enterprise restructuring and failure to develop a well-functioning capital market played major roles in Czech economic troubles, which culminated in a currency crisis in May. The formerly pegged currency was forced into a floating system as investors sold their Korunas faster than the government could buy them. This followed a worldwide trend to divest from developing countries that year. Investors also worried the republic's economic transformation was far from complete. Another complicating factor was the current account deficit, which reached nearly 8% of GDP.
In response to the crisis, two austerity packages were introduced later in the spring (called vernacularly "The Packages"), which cut government spending by 2.5% of GDP. Growth dropped to 0.3% in 1997, −2.3% in 1998, and −0.5% in 1999. The government established a restructuring agency in 1999 and launched a revitalization program – to spur the sale of firms to foreign companies. Key priorities included accelerating legislative convergence with EU norms, restructuring enterprises, and privatising banks and utilities. The economy, fueled by increased export growth and investment, was expected to recover by 2000.
Growth in 2000–05 was supported by exports to the EU, primarily to Germany, and a strong recovery of foreign and domestic investment. Domestic demand is playing an ever more important role in underpinning growth as interest rates drop and the availability of credit cards and mortgages increases. Current account deficits of around 5% of GDP are beginning to decline as demand for Czech products in the European Union increases. Inflation is under control. Recent accession to the EU gives further impetus and direction to structural reform. In early 2004 the government passed increases in the Value Added Tax (VAT) and tightened eligibility for social benefits with the intention to bring the public finance gap down to 4% of GDP by 2006, but more difficult pension and healthcare reforms will have to wait until after the next elections. Privatization of the state-owned telecommunications firm Český Telecom took place in 2005. Intensified restructuring among large enterprises, improvements in the financial sector, and effective use of available EU funds should strengthen output growth.
Growth continued in the first years of the EU membership. The credit portion of the Financial crisis of 2007–2010 did not affect the Czech Republic much, mostly due to its stable banking sector which has learned its lessons during a smaller crisis in the late 1990s and became much more cautious. As a fraction of the GDP, the Czech public debt is among the smallest ones in Central and Eastern Europe. Moreover, unlike many other post-communist countries, an overwhelming majority of the household debt – over 99% – is denominated in the local Czech currency. That's why the country wasn't affected by the shrunken money supply in the U.S. dollars.
However, as a large exporter, the economy was sensitive to the decrease of the demand in Germany and other trading partners. In the middle of 2009, the annual drop of the GDP for 2009 was estimated around 3% or 4.3%, a relatively modest decrease. The impact of the economic crisis may have been limited by the existence of the national currency that temporarily weakened in H1 of 2009, simplifying the life of the exporters.
From the financial crisis of 2007–2010, Czech Republic is in stagnation or decreasing of GDP. Some commenters and economists criticising fiscally conservative policy of Petr Nečas' right-wing government, especially criticising ex-minister of finance, Miroslav Kalousek. Miroslav Kalousek in a 2008 interview, as minister of finance in the center-right government of Mirek Topolánek, said "Czech Republic will not suffer by financial crisis". In September 2008, Miroslav Kalousek formed state budget with projection of 5% GDP increase in 2009. In 2009 and 2010, Czech Republic suffered strong economical crisis and GDP decreased by 4,5%. From 2009 to 2012, Czech Republic suffered highest state budget deficits in history of independent Czech Republic. From 2008 to 2012, the public debt of Czech Republic increased by 18,9%. Most decrease of industrial output was in construction industry (-25% in 2009, -15,5% in 2013). From 4Q 2009 to 1Q 2013, GDP decreased by 7,8%.
In 2012, Czech government increased VAT. Basic VAT was increased from 20% in 2012 to 21% in 2013 and reduced VAT increased from 14% to 15% in 2013. Small enterprises sales decreased by 21% from 2012 to 2013 as result of increasing VAT. Patria.cz predicting sales stagnation and mild increase in 2013. Another problem is foreign trade. The Czech Republic is considered an export economy (the Czech Republic has strong machinery and automobile industries), however in 2013, foreign trade rapidly decreased which led to many other problems and increase of state budget deficit. In 2013, Czech National Bank, central bank, implemented controversial monetary step. To increase export and employment, CNB wilfully deflated Czech Crown (CZK), which inflation increased from 0.2% in November 2013, to 1.3% in 1Q 2014.
In 2014, GDP in the Czech Republic increased by 2% and is predicted to increase by 2.7% in 2015. In 2015, Czech Republic's economy grew by 4,2% and it's the fastest growing economy in the European Union. On 29 May 2015, it was announced that growth of the Czech economy has increased from calculated 3,9% to 4,2%.
In August 2015, Czech GDP growth was 4.4%, making the Czech economy the highest growing in Europe. On 9 November 2015, unemployment in the Czech Republic was at 5.9%, the lowest number since February 2009. Dividends worth CZK 289 billion were paid to the foreign owners of Czech companies in 2016.
Since its accession to the European Union in 2004, the Czech Republic has adopted the Economic and Monetary Union of the European Union and it is bound by the Treaty of Accession 2003 to adopt the Euro currency in the future.
The Czech Republic also receives €24.2bn between 2014 and 2020 from the European Structural and Investment Funds, however, this sum does not outweigh the amount of capital outflow of profits of foreign owned firms from the Czech Republic into other EU members, at which the funds are aimed to compensate for.
As of 2016, the Czech Republic has the second lowest poverty rate of OECD members only behind Denmark. The Czech healthcare system ranks 13th in the 2016 Euro health consumer index.

Signs of economic resurgence began to appear in the wake of the shock therapy that the International Monetary Fund (IMF) labelled the \"big bang\" of January 1991. Since then, consistent liberalization and astute economic management has led to the removal of 95% of all price controls, low unemployment, a positive balance of payments position, a stable exchange rate, a shift of exports from former communist economic bloc markets to Western Europe, and relatively low foreign debt. Inflation has been higher than in some other countries – mostly in the 10% range – and the government has run consistent modest budget deficits.",

With the breakup of the Soviet Union, the country, till that point highly dependent on exports to the USSR, had to make a radical shift in economic outlook: away from the East, and towards the West. This necessitated the restructuring of existing banking and telecommunications facilities, as well as adjusting commercial laws and practices to fit Western standards. Further minimizing reliance on a single major partner, successive Czech governments have welcomed U.S. investment (amongst others) as a counterbalance to the strong economic influence of Western European partners, especially of their powerful neighbour, Germany. Although foreign direct investment (FDI) runs in uneven cycles, with a 12.9% share of total FDI between 1990 and March 1998, the U.S. was the third-largest foreign investor in the Czech economy, behind Germany and the Netherlands.",

"text": "The country boasts a flourishing consumer production sector and has privatized most state-owned heavy industries through the voucher privatization system. Under the system, every citizen was given the opportunity to buy, for a moderate price, a book of vouchers that represents potential shares in any state-owned company. The voucher holders could then invest their vouchers, increasing the capital base of the chosen company, and creating a nation of citizen share-holders. This is in contrast to Russian privatization, which consisted of sales of communal assets to private companies rather than share-transfer to citizens. The effect of this policy has been dramatic. Under communism, state ownership of businesses was estimated to be 97%. Privatization through restitution of real estate to the former owners was largely completed in 1992. By 1998, more than 80% of enterprises were in private hands. Now completed, the program has made Czechs, who own shares of each of the Czech companies, one of the highest per-capita share owners in the world.",

Political and financial crises in 1997 shattered the Czech Republic's image as one of the most stable and prosperous of post-Communist states. Delays in enterprise restructuring and failure to develop a well-functioning capital market played major roles in Czech economic troubles, which culminated in a currency crisis in May. The formerly pegged currency was forced into a floating system as investors sold their Korunas faster than the government could buy them. This followed a worldwide trend to divest from developing countries that year. Investors also worried the republic's economic transformation was far from complete. Another complicating factor was the current account deficit, which reached nearly 8% of GDP.",

Recent accession to the EU gives further impetus and direction to structural reform. In early 2004 the government passed increases in the Value Added Tax (VAT) and tightened eligibility for social benefits with the intention to bring the public finance gap down to 4% of GDP by 2006, but more difficult pension and healthcare reforms will have to wait until after the next elections.

As a fraction of the GDP, the Czech public debt is among the smallest ones in Central and Eastern Europe.

5,851 | Transport in the Czech Republic | Transport in the Czech Republic relies on several main modes, including transport by road, rail, water and air.
The Czech Republic has a total railway length of 9,435 kilometres (5,863 mi). The vast majority (9,341 kilometres (5,804 mi)) is standard gauge. Electrified railways generally have voltages of 3 kV DC or 25 kV AC. 94 kilometres (58 mi) of track is narrow gauge. The most prominent Czech railway company is the state-owned České dráhy (ČD) (English: Czech Railways). Prague has an underground rapid transit system, the Prague Metro. In addition, the cities of Brno, Liberec, Most, Olomouc, Ostrava, Plzeň, and Prague have tram systems.
The Czech Republic has, in total, 55,653 km (34,581 mi) of roads. It has 1,247 km (775 mi) of motorways. In the 1980s and 1990s there was a significant increase in passenger transport on the roads in the Czech Republic, which was associated with a sharp increase in the accident rate. Between 2007 and 2013, the death rate fell in every year, with a record low of 583 deaths in 2013, compared with the 1994 high of 1,473 casualties. Despite this however, the fatality rate per head of population is moderately high, comparable to the United States.
There are 2 main categories of roads forming the main network: Motorways and Highways. These roads are managed by the state-owned Directorate of Highways and Motorways of the Czech Republic – ŘSD, established in 1997. Among the first modern motorways in the Czech Republic was the motorway from Prague to the Slovak border through Brno whose construction was started on May 2, 1939.
Motorways are dual carriageways with tolls and a speed limit of 130 km/h. Highways can be single and dual carriageway with a speed limit of 90 km/h (dual carriageways are commonly signposted as Roads for motorcars with a speed limit of 110 km/h).
ŘSD currently manages and maintains 1,369 km of motorways (dálnice).
The Vltava is the country's longest river, at 430 km. 358 km of the Elbe (Labe), which totals 1154 km, is also present in the country. An artificial waterway, nowadays used for recreation, is the Baťa Canal.
Děčín, Mělník, Prague, Ústí nad Labem, Moldauhafen in Hamburg (no longer operational, will be handed over to Germany in 2028)
In 2006, the Czech Republic had a total 121 airports. 46 of these airports had paved runways while 75 had unpaved runways. The largest and busiest airport in the Czech Republic is Václav Havel Airport Prague, opened in 1937. Other international airports include Brno–Tuřany Airport, Karlovy Vary Airport, Ostrava Leoš Janáček Airport, Pardubice Airport, Kunovice Airport and Public domestic and private international airport is for example Hradec Králové Airport.

5,853 | Army of the Czech Republic | The Army of the Czech Republic (Czech: Armáda České republiky, AČR), also known as the Czech Army, is the military service responsible for the defence of the Czech Republic as part of the Armed Forces of the Czech Republic (Czech: ozbrojené síly České republiky) alongside the Military Office of the President of the Republic and the Castle Guard. The Army consists of the General Staff, the Land Forces, the Air Force and support units.
Czech Army's main historical legacy and inspiration stems from the 15th century Hussite militia, which is credited with numerous warfare advancements, including introduction of firearms to field battles as well as wagon fort strategy. Modern history precedes the 1918 Czechoslovak declaration of independence with formal establishment of the Czechoslovak Legion fighting on the side of the Entente powers during the WW1. Following the Munich Agreement, the country was occupied by Nazi Germany and the Army was reconstituted in exile, fighting on the side of Allies of World War II in the European as well as Mediterranean and Middle East theatre. After the 1948 Communist Coup, the Czechoslovak People's Army with over 200,000 active personnel and some 4,500 tanks formed one of the pillars of the Warsaw Pact military alliance.
Following the Velvet Revolution and dissolution of Czechoslovakia, the Czech Republic joined NATO in 1999. The conscription was abolished in 2004, leading to transformation into a modern professional army inspired mostly by the British Armed Forces and USMC example. Today, the Czech Army has 27.000 professional personnel and 4.000 members of active reserves. Additionally, any citizen can voluntarily join a five week basic training without becoming a soldier or join advanced shooting training with their privately owned firearms and become civilian reservist.
A law adopted in June 2023 stipulates that the military expenditures shall not be lower than 2% of country's GDP, starting from 2024.
The military history of the Czech people dates back to the Middle Ages and the creation of the Duchy of Bohemia and the Kingdom of Bohemia. During the Hussite Wars, Jan Žižka became a military leader of such skill and eminence that the Hussite legacy became an important and lasting part of the Czech military traditions.
Official military names since 1918:
1918–1950 - Czechoslovak Armed Forces (this official name was given to the Czechoslovak Army on March 19, 1920 on the basis of the Armed Forces Act)
1950–1954 - Czechoslovak Army
1954–1989 - Czechoslovak People's Army
1990–1992 - Czechoslovak Army
since 1993 - Army of the Czech Republic (ACR)
The Czechoslovak Armed Forces were originally formed on 30 June 1918 when 6,000 members of the Czechoslovak Legion in France, which had been established in 1914, took oath and received a battle banner in Darney, France, thus preceding the official declaration of Czechoslovak independence by four months. There were also 50 000 legion soldiers in Russia at that time. The military achievements of the Czechoslovak legions on the French, Italian and especially Russian front became one of the main arguments that the Czechoslovak pro-independence leaders, especially for T. G. Masaryk in America, could use to gain the support for the country's independence by the Allies of World War I.
In 1938, servicemen of the Czechoslovak Army and the State Defense Guard fought in an undeclared border war against the German-backed Sudetendeutsches Freikorps as well as Polish and Hungarian paramilitary forces. As a result of the Munich Agreement, areas heavily populated by ethnic German speaking people were incorporated into the Third Reich and military-aged men living there were subject to being drafted into the Wehrmacht. In 1939, after the Slovak State proclaimed its independence and the remainder of Carpathian Ruthenia was occupied and annexed by Hungary, the German occupation of the Czech Lands followed and the Protectorate of Bohemia and Moravia was proclaimed after the negotiations with Emil Hácha. The Protectorate's government possessed its own armed force, the Government Army (6,500 men), tasked with public security and rearguard duties. On the other side of the conflict, a number of Czechoslovak units and formations served with the Polish Army (Czechoslovak Legion), the French Army, the Royal Air Force, the British Army (the 1st Czechoslovak Armoured Brigade), and the Red Army (I Corps). Four Czech and Slovak-manned RAF squadrons were transferred to Czechoslovak control in late 1945.
From 1954 until 1989, the Army was known as the Czechoslovak People's Army (ČSLA). Although the ČSLA, as formed in 1945, included both Soviet- and British-equipped/trained expatriate troops, the "Western" soldiers had been purged from the ČSLA after 1948 when the communists took power. The ČSLA offered no resistance to the invasion mounted by the Soviets in 1968 in reaction to the "Prague Spring", and was extensively reorganized by the Soviets following the re-imposition of communist rule in Prague.
Of the approximately 201,000 personnel on active duty in the ČSLA in 1987, about 145,000, or about 72 percent, served in the ground forces (commonly referred to as the army). About 100,000 of these were conscripts. There were two military districts, Western and Eastern. A 1989 listing of forces shows two Czechoslovak armies in the west, the 1st Army at Příbram with one tank division and three motor rifle divisions, the 4th Army at Písek with two tank divisions and two motor rifle divisions. In the Eastern Military District, there were two tank divisions, the 13th and 14th, with a supervisory headquarters at Trenčín in the Slovak part of the country.
During the Cold War, the ČSLA was equipped primarily with Soviet arms, although certain arms like the OT-64 SKOT armored personnel carrier, the L-29 Delfín and L-39 Albatros aircraft, the P-27 Pancéřovka antitank rocket launcher, the vz. 58 assault rifle or the Uk vz. 59 machine gun were of Czechoslovak design.
After the fall of communism during the Velvet Revolution in 1989, the Czechoslovak People's Army was renamed back to the Czechoslovak Army and was completely transformed as well.
The Army of the Czech Republic was formed after the Czechoslovak Armed Forces split after the 31 December 1992 peaceful dissolution of Czechoslovakia. Czech forces stood at 90,000 in 1993. They were reduced to around 65,000 in 11 combat brigades and the Air Force in 1997, to 63,601 in 1999, and to 35,000 in 2005. At the same time, the forces were modernized and reoriented towards a defensive posture. In 2004, the army transformed itself into a fully professional organization and compulsory military service was abolished. The Army maintains an active reserve.
The Czech Republic is a member of the United Nations and the Organization for Security and Co-operation in Europe. In March 1999, the Czech Republic joined NATO. Since 1990, the ACR and the Czech Armed Forces have contributed to numerous peacekeeping and humanitarian operations, including IFOR, SFOR, and EUFOR Althea in Bosnia, Desert Shield/Desert Storm, Afghanistan, Kosovo, Albania, Turkey, Pakistan and with the Coalition forces in Iraq.

Many of the duties of the President of the Czech Republic can be said to be ceremonial to one degree or another, especially since the President has relatively few powers independent of the will of the Prime Minister. One of those is the status as commander in chief of the military; no part of these duties can take place but through the assent of the Prime Minister. In matters of war, he is in every sense merely a figurehead, since the Constitution gives all substantive constitutional authority over the use of the armed forces to the Parliament. In fact, the only specific thing the constitution allows the President to do with respect to the military is to appoint its generals – but even this must be done with the signature of the Prime Minister.
Structure of the Czech Armed Forces consists of two main parts and other commands:
Active Reserve (in Czech Aktivní záloha) is a part of the otherwise professional Army of the Czech Republic. This service was created to allow the participation of citizens with a positive attitude to the military.
A volunteer needs either to have completed the compulsory military service (which ended in 2004) or to attend 6 week training. Then the reservists have to serve up to three weeks a year and can be called up to serve two weeks during a non-military crisis. They are not intended to serve abroad, but individuals may volunteer to do so. The Reserve presents itself on events like BAHNA, a military show.
Each of the active duty brigades or regiments have their own active reserve subordinate units that train with the same equipment as the professional soldiers and is part of the organisational structure usually as a 4th company in a battalion. The Territorial Command is responsible for the active reserves and have direct control of the 14 infantry companies that belong to regional military commands in each of the 13 regions and capital city Prague.
The Army of the Czech Republic, to a large extent, currently uses equipment dating back to the times of the Warsaw Pact. During the Cold War, Czechoslovakia was a major supplier of tanks, armoured personnel carriers, military trucks and trainer aircraft – the bulk of military exports went to its Comecon partners. Replacement of aging or obsolete equipment, or making it at least compliant with NATO standards, is urgently required. Modernization plans include acquisition of new multi-role helicopters, transport aircraft, infantry fighting vehicles, air defence radars and missiles. If possible, the Czech Ministry of Defence selects products that are manufactured or co-produced in the Czech Republic. This includes firearms of the Česká zbrojovka Uherský Brod, namely the CZ 75 pistol, CZ Scorpion Evo 3 submachine gun, and CZ 805 BREN and BREN 2 assault rifles. Moreover, the Czech Army is equipped with about 3,000 T810 and T815 vehicles of various modifications produced by the Czech Tatra Trucks company. Tatra Defence Vehicle factory ensures licensed production of Pandur II and Titus armoured vehicles. Aircraft such as the Aero L-39 Albatros, Aero L-159 Alca and Let L-410 Turbolet have been produced domestically as well.
At the beginning of 2019, the Czech Ministry of Defence announced its modernization program, consisting of acquiring 210 new modern IFVs as a replacement for the aging BVP-2. MoD approached four manufacturers: BAE Systems (CV90), GDELS (ASCOD), Rheinmetall (Lynx) and PSM (Puma). The cost of the program is expected to exceed 50 billion CZK.
In May 2022 the Czech Ministry of Defence announced it will get 15 Leopards 2A4 from Germany as an exchange for Czech tanks that will be given to Ukraine to help defend against Russian invasion and will purchase up to 50 modern 2A7+ variants later.

5,855 | Foreign relations of the Czech Republic | The Czech Republic is a Central European country, a member of the European Union, the Organisation for Economic Co-operation and Development (OECD), Organization for Security and Co-operation in Europe (OSCE), the North Atlantic Treaty Organization (NATO), the United Nations (and all of its main specialized agencies and boards). It entertains diplomatic relations with 191 countries of the world, around half of which maintain a resident embassy in the Czech capital city, Prague.
During the years 1948–1989, the foreign policy of Czechoslovakia had followed that of the Soviet Union. Since the revolution and the subsequent mutually-agreed peaceful dissolution of Czechoslovakia into the Czech Republic and Slovakia, the Czechs have made reintegration with Western institutions their chief foreign policy objective. This goal was rapidly met with great success, as the nation joined NATO in 1999 and the European Union in 2004, and held the Presidency of the European Union during the first half of 2009.
Throughout the past decades, Liechtenstein continuously claimed restitution for 1,600 km (620 sq mi), or an area roughly ten times the size of Liechtenstein, of land currently located in the Czech Republic. The land was partially confiscated from the Liechtenstein family in 1918 with the rest of the property being confiscated in 1945 after the expulsion of Germans and confiscation of German property. The Czech Republic insisted that it could not acknowledge or be responsible for claims going back to before February 1948, when the Communists had seized power.
As a result, Liechtenstein did not diplomatically recognize the existence of the Czech Republic as a new state (and, for that matter, also that of the Slovak Republic) until 2009.
In July 2009, the Prince of Liechtenstein announced he was resigning to the previous unsuccessful claims to property located in the Czech Republic, and on 13 July 2009, after politically recognizing one another, the Czech Republic and Liechtenstein formally established diplomatic relations.
In February 2007, the US started formal negotiations with Czech Republic and Poland concerning construction of missile shield installations in those countries for a Ground-based Midcourse Defense System. Government of the Czech Republic agrees (while 67% Czechs disagree and only about 22% support it) to host a missile defense radar on its territory while a base of missile interceptors is supposed to be built in Poland. The objective is reportedly to protect another parts of US National Missile Defense from long-range missile strikes from Iran and North Korea, but Czech PM Mirek Topolánek said the main reason is to avoid Russian influence and strengthen ties to US.
The main government supporter Alexandr Vondra, Deputy Prime Minister for European affairs, used to be an ambassador to the USA. More problematic is that between 2004 and 2006 he was an executive director of a lobbying company Dutko Worldwide Prague. Dutko's and its strategic partner AMI Communications (PR company) customers are Boeing, Lockheed Martin, Nortrop Grumman, which are largest contractors for NMD development. AMI Communications also received (without a formal selection procedure) a government contract to persuade Czechs to support US radar base.

] | The Czech Republic is a Central European country, a member of the European Union, the Organisation for Economic Co-operation and Development (OECD), Organization for Security and Co-operation in Europe (OSCE), the North Atlantic Treaty Organization (NATO), the United Nations. It entertains diplomatic relations with 191 countries of the world, around half of which maintain a resident embassy in the Czech capital city, Prague. During the years 1948–1989, the foreign policy of Czechoslovakia had followed that of the Soviet Union. Since the revolution and the subsequent mutually-agreed peaceful dissolution of Czechoslovakia into the Czech Republic and Slovakia, the Czechs have made reintegration with Western institutions their chief foreign policy objective. This goal was rapidly met with great success, as the nation joined NATO in 1999 and the European Union in 2004, and held the Presidency of the European Union during the first half of 2009. | 2002-02-25T15:51:15Z | 2023-12-26T07:28:26Z | [

5,857 | Climbing | Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders) to small boulders. Climbing is done for locomotion, sporting recreation, for competition, and is also done in trades that rely on ascension, such as rescue and military operations. Climbing is done indoors and outdoors, on natural surfaces (e.g. rock climbing and ice climbing), and on artificial surfaces (e.g. climbing walls and climbing gyms)
The sport of climbing has evolved by climbers making first ascents of new types of climbing routes, using new climbing techniques, at ever-increasing grades of difficulty, with ever-improving pieces of climbing equipment. Mountain guides were an important element in developing the popularity of the sport in the natural environment. Early pioneers included Walter Bonatti, Riccardo Cassin, Hermann Buhl, and Gaston Rébuffat, who were followed by and Reinhold Messner and Doug Scott, and laterly by Mick Fowler and Marko Prezelj, and Ueli Steck. Since the 1980s, the development of the safer format of bolted sport climbing, the wider availability of artificial climbing walls and climbing gyms, and the development of competition climbing, dramatically increased the popularity of rock climbing as a sport, and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Alexander Huber, Chris Sharma, Adam Ondra, Lynn Hill, Catherine Destivelle, and Janja Garnbret.
Climbing became an Olympic sport for the first time in the 2021 Olympic Games in Tokyo (see Sport climbing at the 2020 Summer Olympics) in that format that included competition lead climbing, competition bouldering, and competition speed climbing disciplines; competition ice climbing is not yet an Olympic sport.
Rock climbing can trace its origins to the late 19th-century, and has since developed into a number of main sub-disciplines. Single-pitch and multi-pitch (and big wall), can be performed in varying styles (including aid, sport, traditional, and free solo), while the discipline of bouldering, is by definition performed in a free solo format.
Competition climbing (sometimes confusingly called "sport climbing"), is a regulated sport of competitive rock climbing that originated in the 1980s, and which is usually done as indoor climbing on artificial climbing walls. The International Federation of Sport Climbing (IFSC) is the official governing body for competition rock-climbing worldwide and is recognized by the IOC and GAISF and is a member of the International World Games Association (IWGA). The UIAA is the official governing body for competition ice climbing worldwide. Competition climbing has three major disciplines:
Climbing has been the subject of both narrative and documentary films. Notable climbing films include Touching the Void (2003), Everest (2015), Meru (2015), The Dawn Wall (2015), Free Solo (2018), 14 Peaks: Nothing Is Impossible (2021), and The Alpinist (2021).

5,859 | Continuity Irish Republican Army | The Continuity Irish Republican Army (Continuity IRA or CIRA), styling itself as the Irish Republican Army (Irish: Óglaigh na hÉireann), is an Irish republican paramilitary group that aims to bring about a united Ireland. It claims to be a direct continuation of the original Irish Republican Army and the national army of the Irish Republic that was proclaimed in 1916. It emerged from a split in the Provisional IRA in 1986 but did not become active until the Provisional IRA ceasefire of 1994. It is an illegal organisation in the Republic of Ireland and is designated a terrorist organisation in the United Kingdom, New Zealand and the United States. It has links with the political party Republican Sinn Féin (RSF).
Since 1994, the CIRA has waged a campaign in Northern Ireland against the British Army and the Police Service of Northern Ireland (PSNI), formerly the Royal Ulster Constabulary. This is part of a wider campaign against the British security forces by dissident republican paramilitaries. It has targeted the security forces in gun attacks and bombings, as well as with grenades, mortars and rockets. The CIRA has also carried out bombings with the goal of causing economic harm and/or disruption, as well as many punishment attacks on alleged criminals.
To date, it has been responsible for the death of one PSNI officer. The CIRA is smaller and less active than the Real IRA, and there have been a number of splits within the organisation since the mid-2000s.
The Continuity IRA has its origins in a split in the Provisional IRA. In September 1986, the Provisional IRA held a General Army Convention (GAC), the organisation's supreme decision-making body. It was the first GAC in 16 years. The meeting, which like all such meetings was secret, was convened to discuss among other resolutions, the articles of the Provisional IRA constitution which dealt with abstentionism, specifically its opposition to the taking of seats in Dáil Éireann (the parliament of the Republic of Ireland). The GAC passed motions (by the necessary two-thirds majority) allowing members of the Provisional IRA to discuss and debate the taking of parliamentary seats, and the removal of the ban on members of the organisation from supporting any successful republican candidate who took their seat in Dáil Éireann.
The Provisional IRA convention delegates opposed to the change in the constitution claimed that the convention was gerrymandered "by the creation of new IRA organisational structures for the convention, including the combinations of Sligo-Roscommon-Longford and Wicklow-Wexford-Waterford." The only IRA body that supported this viewpoint was the outgoing IRA Executive. Those members of the outgoing Executive who opposed the change comprised a quorum. They met, dismissed those in favour of the change, and set up a new Executive. They contacted Tom Maguire, who was a commander in the old IRA and had supported the Provisionals against the Official IRA (see Irish republican legitimatism), and asked him for support. Maguire had also been contacted by supporters of Gerry Adams, then president of Sinn Féin, and a supporter of the change in the Provisional IRA constitution.
Maguire rejected Adams' supporters, supported the IRA Executive members opposed to the change, and named the new organisers the Continuity Army Council. In a 1986 statement, he rejected "the legitimacy of an Army Council styling itself the Council of the Irish Republican Army which lends support to any person or organisation styling itself as Sinn Féin and prepared to enter the partition parliament of Leinster House." In 1987, Maguire described the "Continuity Executive" as the "lawful Executive of the Irish Republican Army."
Initially, the Continuity IRA did not reveal its existence, either in the form of press statements or paramilitary activity. Although the Garda Síochána had suspicions that the organisation existed, they were unsure of its name, labelling it the "Irish National Republican Army". On 21 January 1994, on the 75th anniversary of the First Dáil Éireann, a group of men in paramilitary dress offered a "final salute" to Tom Maguire by firing over his grave. A public statement headed "Irish Republican Publicity Bureau" signed "B Ó Ruairc, Rúnaí [Secretary]" identifying the firing party as "Volunteers of Óglaigh na hÉireann-the Irish Republican Army", and two accompanying photos were published in Saoirse Irish Freedom. Garda Special Branch detectives raided the headquarters of Republican Sinn Féin at Arran Quay, Dublin, two days after the graveside volley, seizing files and questioning staff. In February 1994 it was reported that in previous months Gardaí had found arms dumps along the Cooley Peninsula in County Louth that did not belong to the Provisional IRA, and forensics tests determined had been used for firing practice recently.
It was only after the Provisional IRA declared a ceasefire in 1994 that the Continuity IRA became active, announcing its intention to continue the campaign against British rule. The CIRA continues to oppose the Good Friday Agreement and, unlike the Provisional IRA (and the Real IRA in 1998), the CIRA has not announced a ceasefire or agreed to participate in weapons decommissioning—nor is there any evidence that it will. In the 18th Independent Monitoring Commission's report, the RIRA, the CIRA and the Irish National Liberation Army (INLA) were deemed a potential future threat. The CIRA was labelled "active, dangerous and committed and... capable of a greater level of violent and other crime". Like the RIRA and RIRA splinter group Óglaigh na hÉireann, it too sought funds for expansion. It is also known to have worked with the INLA.
The CIRA has been involved in a number of bombing and shooting incidents. Targets of the CIRA have included the British military, the Northern Ireland police (both the Royal Ulster Constabulary and its successor the Police Service of Northern Ireland). Since the Good Friday Agreement in 1998 the CIRA, along with other paramilitaries opposing the ceasefire, have been involved with a countless number of punishment shootings and beatings. By 2005 the CIRA was believed to be an established presence on the island of Great Britain with the capability of launching attacks. A bomb defused in Dublin in December 2005 was believed to have been the work of the CIRA. In February 2006, the Independent Monitoring Commission (IMC) blamed the CIRA for planting four bombs in Northern Ireland during the final quarter of 2005, as well as several hoax bomb warnings. The IMC also blamed the CIRA for the killings of two former CIRA members in Belfast, who had stolen CIRA weapons and established a rival organisation. The CIRA continued to be active in both planning and undertaking attacks on the PSNI. The IMC said they tried to lure police into ambushes, while they have also taken to stoning and using petrol bombs. In addition, other assaults, robbery, tiger kidnapping, extortion, fuel laundering and smuggling were undertaken by the group. The CIRA also actively took part in recruiting and training members, including disgruntled former Provisional IRA members. As a result of this continued activity the IMC said the group remained "a very serious threat".
On 10 March 2009 the CIRA claimed responsibility for the fatal shooting of a PSNI officer in Craigavon, County Armagh—the first police fatality in Northern Ireland since 1998. The officer was fatally shot by a sniper as he and a colleague investigated "suspicious activity" at a house nearby when a window was smashed by youths causing the occupant to phone the police. The PSNI officers responded to the emergency call, giving a CIRA sniper the chance to shoot and kill officer Stephen Carroll. Carroll was killed two days after the Real IRA's 2009 Massereene Barracks shooting at Massereene Barracks in Antrim. In a press interview with Republican Sinn Féin some days later, regarded by some to be the political wing of the Continuity IRA, Richard Walsh described the attacks as "acts of war".
In 2013, the Continuity IRA's 'South Down Brigade' threatened a Traveller family in Newry and published a statement in the local newspaper. There were negotiations with community representatives and the CIRA announced the threat was lifted. It was believed the threat was issued after a Traveller feud which resulted in a pipe bomb attack in Bessbrook, near Newry. The Continuity IRA is believed to be strongest in the County Fermanagh – North County Armagh area (Craigavon, Armagh and Lurgan). It is believed to be behind a number of attacks such as pipe bombings, rocket attacks, gun attacks, and the PSNI claimed it orchestrated riots a number of times to lure police officers into areas such as Kilwilkie in Lurgan and Drumbeg in Craigavon in order to attack them. It also claimed the group orchestrated a riot during a security alert in Lurgan. The alert turned out to be a hoax.
On Easter 2016, the Continuity IRA marched in paramilitary uniforms through North Lurgan, Co Armagh, without any hindrance from the PSNI who monitored the parade from a police helicopter.
In July and August 2019 the CIRA carried out attempted bomb attacks on the PSNI in Craigavon, County Armagh and Wattlebridge, County Fermanagh.
On 5 February 2020, a bomb planted by the CIRA was found by the PSNI in a lorry in Lurgan. The CIRA believed the lorry was going to be put on a North Channel ferry to Scotland in January 2020.
Similar to the claim put forward by the Provisional IRA after its split from the Official IRA in 1969, the Continuity IRA claims to be the legitimate continuation of the original Irish Republican Army or Óglaigh na hÉireann. This argument is based on the view that the surviving anti-Treaty members of the Second Dáil delegated their "authority" to the IRA Army Council in 1938. As further justification for this claim, Tom Maguire, one of those anti-Treaty members of the Second Dáil, issued a statement in favour of the Continuity IRA, just as he had done in 1969 in favour of the Provisionals. J. Bowyer Bell, in his The Irish Troubles, describes Maguire's opinion in 1986: "abstentionism was a basic tenet of republicanism, a moral issue of principle. Abstentionism gave the movement legitimacy, the right to wage war, to speak for a Republic all but established in the hearts of the people". Maguire's stature was such that a delegation from Gerry Adams sought his support in 1986, but was rejected.
These changes within the IRA were accompanied by changes on the political side and at the 1986 Sinn Féin Ard Fheis (party conference), which followed the IRA Convention, the party's policy of abstentionism, which forbade Sinn Féin elected representatives from taking seats in the Oireachtas, the parliament of the Republic, was dropped. On 2 November, the 628 delegates present cast their votes, the result being 429 to 161. The traditionalists, having lost at both conventions, walked out of the Mansion House, met that evening at the West County Hotel, and reformed as Republican Sinn Féin (RSF).
According to a report in the Cork Examiner, the Continuity IRA's first chief of staff was Dáithí Ó Conaill, who also served as the first chairman of RSF from 1986 to 1987. The Continuity IRA and RSF perceive themselves as forming a "true" Republican Movement.
The leadership of the Continuity IRA is believed to be based in the provinces of Munster and Ulster. It was alleged that its chief of staff was a Limerick man and that a number of other key members were from that county, until their expulsion. Dáithí Ó Conaill was the first chief of staff until 1991. In 2004 the United States (US) government believed the Continuity IRA consisted of fewer than fifty hardcore activists. In 2005, Irish Minister for Justice, Equality and Law Reform Michael McDowell told Dáil Éireann that the organisation had a maximum of 150 members.
The CIRA is an illegal organisation under UK (section 11(1) of the Terrorism Act 2000) and ROI law due to the use of 'IRA' in the group's name, in a situation analogous to that of the Real Irish Republican Army (RIRA). Membership of the organisation is punishable by a sentence of up to ten years imprisonment under UK law. On 31 May 2001 Dermot Gannon became the first person to be convicted of membership of the CIRA solely on the word of a Garda Síochána chief superintendent. On 13 July 2004, the US government designated the CIRA as a 'Foreign Terrorist Organization'. This made it illegal for Americans to provide material support to the CIRA, requires US financial institutions to block the group's assets and denies alleged CIRA members visas into the US.
The US government suspects the Continuity IRA of having received funds and arms from supporters in the United States. Security sources in Ireland have expressed the suspicion that, in co-operation with the RIRA, the Continuity IRA may have acquired arms and materiel from the Balkans. They also suspect that the Continuity IRA arsenal contains some weapons that were taken from Provisional IRA arms dumps, including a few dozen rifles, machine guns, and pistols; a small amount of the explosive Semtex; and a few dozen detonators.
In 2005, several members of the CIRA, who were serving prison sentences in Portlaoise Prison for paramilitary activity, left the organisation. Some transferred to the INLA landing of the prison, but the majority of those who left are now independent and on E4 landing. The remaining CIRA prisoners have moved to D Wing. Supporters of the Continuity IRA leadership claim that this resulted from an internal disagreement, which although brought to a conclusion, was followed by some people leaving the organisation anyway. Supporters of the disaffected members established the Concerned Group for Republican Prisoners. Most of those who had left went back to the CIRA, or dissociated themselves from the CGRP, which is now defunct.
In February 2006, the Independent Monitoring Commission claimed in a report on paramilitary activity that two groups, styling themselves as "Óglaigh na hÉireann" and "Saoirse na hÉireann", had been formed after a split in the Continuity IRA either in early 2006 or late 2005. The Óglaigh na hÉireann group was responsible for a number of pipe bomb attacks on the PSNI, bomb hoaxes, and robberies, the IMC also claimed the organisation was responsible for the killing of Andrew Burns on 12 February 2008 and was seeking to recruit former members of the RIRA. The Saoirse na hÉireann (SNH) group was composed of "disaffected and largely young republicans" and was responsible for a number of bomb hoaxes, two of which took place in September 2006. It was thought to have operated largely in republican areas of Belfast . The groups had apparently ceased operations by early 2009.
In 2007, the Continuity IRA was responsible for shooting dead two of its members who had left and attempted to create their own organisation. Upon leaving the CIRA, they had allegedly taken a number of guns with them. The Continuity IRA is believed by Gardaí to have been involved in a number of gangland killings in Dublin and Limerick.
In July 2010, members of a "militant Northern-based faction within the CIRA" led by a well-known member from south Londonderry claimed to have overthrown the leadership of the organisation. They also claimed that an Army Convention representing "95 per cent of volunteers" had unanimously elected a new 12-member Army Executive, which in turn appointed a new seven-member Army Council. The moves came as a result of dissatisfication with the southern-based leadership and the apparent winding-down of military operations. A senior source from RSF said: "We would see them [the purported new leadership] as just another splinter group that has broken away." This organisation is referred to as the Real CIRA.
In June 2011 CIRA member Liam Kenny was murdered, allegedly by drug dealers, at his home in Clondalkin, West Dublin. On 28 November 2011 an innocent man was mistakenly shot dead in retaliation for the murder of Liam Kenny. Limerick Real IRA volunteer Rose Lynch pleaded guilty to this murder at the Special Criminal Court and was sentenced to life imprisonment.
In July 2012 the CIRA announced it had a new leadership after expelling members who had been working against the organisation.
In April 2014 a former leading member of the Belfast Continuity IRA who had been expelled from the organisation, Tommy Crossan, was shot dead.
The CIRA are depicted in RTÉ's TV series crime drama Love/Hate. | [

A bomb defused in Dublin in December 2005 was believed to have been the work of the CIRA. In February 2006, the Independent Monitoring Commission (IMC) blamed the CIRA for planting four bombs in Northern Ireland during the final quarter of 2005, as well as several hoax bomb warnings. The IMC also blamed the CIRA for the killings of two former CIRA members in Belfast, who had stolen CIRA weapons and established a rival organisation. The CIRA continued to be active in both planning and undertaking attacks on the PSNI. The IMC said they tried to lure police into ambushes, while they have also taken to stoning and using petrol bombs. In addition, other assaults, robbery, tiger kidnapping, extortion, fuel laundering and smuggling were undertaken by the group. The CIRA also actively took part in recruiting and training members, including disgruntled former Provisional IRA members. As a result of this continued activity the IMC said the group remained \"a very serious threat\".",

] | The Continuity Irish Republican Army, styling itself as the Irish Republican Army, is an Irish republican paramilitary group that aims to bring about a united Ireland. It claims to be a direct continuation of the original Irish Republican Army and the national army of the Irish Republic that was proclaimed in 1916. It emerged from a split in the Provisional IRA in 1986 but did not become active until the Provisional IRA ceasefire of 1994. It is an illegal organisation in the Republic of Ireland and is designated a terrorist organisation in the United Kingdom, New Zealand and the United States. It has links with the political party Republican Sinn Féin (RSF). Since 1994, the CIRA has waged a campaign in Northern Ireland against the British Army and the Police Service of Northern Ireland (PSNI), formerly the Royal Ulster Constabulary. This is part of a wider campaign against the British security forces by dissident republican paramilitaries. It has targeted the security forces in gun attacks and bombings, as well as with grenades, mortars and rockets. The CIRA has also carried out bombings with the goal of causing economic harm and/or disruption, as well as many punishment attacks on alleged criminals. To date, it has been responsible for the death of one PSNI officer. The CIRA is smaller and less active than the Real IRA, and there have been a number of splits within the organisation since the mid-2000s. | 2023-05-28T22:24:44Z | [

5,863 | Copenhagen interpretation | The Copenhagen interpretation is a collection of views about the meaning of quantum mechanics, stemming from the work of Niels Bohr, Werner Heisenberg, Max Born, and others. The term "Copenhagen interpretation" was apparently coined by Heisenberg during the 1950s to refer to ideas developed in the 1925–1927 period, glossing over his disagreements with Bohr. Consequently, there is no definitive historical statement of what the interpretation entails.
Features common across versions of the Copenhagen interpretation include the idea that quantum mechanics is intrinsically indeterministic, with probabilities calculated using the Born rule, and the principle of complementarity, which states that objects have certain pairs of complementary properties that cannot all be observed or measured simultaneously. Moreover, the act of "observing" or "measuring" an object is irreversible, and no truth can be attributed to an object except according to the results of its measurement (that is, the Copenhagen interpretation rejects counterfactual definiteness). Copenhagen-type interpretations hold that quantum descriptions are objective, in that they are independent of physicists' personal beliefs and other arbitrary mental factors.
Over the years, there have been many objections to aspects of Copenhagen-type interpretations, including the discontinuous and stochastic nature of the "observation" or "measurement" process, the apparent subjectivity of requiring an observer, the difficulty of defining what might count as a measuring device, and the seeming reliance upon classical physics in describing such devices. Still, including all the variations, the interpretation remains one of the most commonly taught.
Starting in 1900, investigations into atomic and subatomic phenomena forced a revision to the basic concepts of classical physics. However, it was not until a quarter-century had elapsed that the revision reached the status of a coherent theory. During the intervening period, now known as the time of the "old quantum theory", physicists worked with approximations and heuristic corrections to classical physics. Notable results from this period include Max Planck's calculation of the blackbody radiation spectrum, Albert Einstein's explanation of the photoelectric effect, Einstein and Peter Debye's work on the specific heat of solids, Niels Bohr and Hendrika Johanna van Leeuwen's proof that classical physics cannot account for diamagnetism, Bohr's model of the hydrogen atom and Arnold Sommerfeld's extension of the Bohr model to include relativistic effects. From 1922 through 1925, this method of heuristic corrections encountered increasing difficulties; for example, the Bohr–Sommerfeld model could not be extended from hydrogen to the next simplest case, the helium atom.
The transition from the old quantum theory to full-fledged quantum physics began in 1925, when Werner Heisenberg presented a treatment of electron behavior based on discussing only "observable" quantities, meaning to Heisenberg the frequencies of light that atoms absorbed and emitted. Max Born then realized that in Heisenberg's theory, the classical variables of position and momentum would instead be represented by matrices, mathematical objects that can be multiplied together like numbers with the crucial difference that the order of multiplication matters. Erwin Schrödinger presented an equation that treated the electron as a wave, and Born discovered that the way to successfully interpret the wave function that appeared in the Schrödinger equation was as a tool for calculating probabilities.
Quantum mechanics cannot easily be reconciled with everyday language and observation, and has often seemed counter-intuitive to physicists, including its inventors. The ideas grouped together as the Copenhagen interpretation suggest a way to think about how the mathematics of quantum theory relates to physical reality.
The term refers to the city of Copenhagen in Denmark, and was apparently coined during the 1950s. Earlier, during the mid-1920s, Heisenberg had been an assistant to Bohr at his institute in Copenhagen, where they helped originate quantum mechanical theory. At the 1927 Solvay Conference, a dual talk by Max Born and Heisenberg declared "we consider quantum mechanics to be a closed theory, whose fundamental physical and mathematical assumptions are no longer susceptible of any modification." In 1929, Heisenberg gave a series of invited lectures at the University of Chicago explaining the new field of quantum mechanics. The lectures then served as the basis for his textbook, The Physical Principles of the Quantum Theory, published in 1930. In the book's preface, Heisenberg wrote:
On the whole, the book contains nothing that is not to be found in previous publications, particularly in the investigations of Bohr. The purpose of the book seems to me to be fulfilled if it contributes somewhat to the diffusion of that 'Kopenhagener Geist der Quantentheorie' [Copenhagen spirit of quantum theory] if I may so express myself, which has directed the entire development of modern atomic physics.
The term 'Copenhagen interpretation' suggests something more than just a spirit, such as some definite set of rules for interpreting the mathematical formalism of quantum mechanics, presumably dating back to the 1920s. However, no such text exists, and the writings of Bohr and Heisenberg contradict each other on several important issues. It appears that the particular term, with its more definite sense, was coined by Heisenberg around 1955, while criticizing alternative "interpretations" (e.g., David Bohm's) that had been developed. Lectures with the titles 'The Copenhagen Interpretation of Quantum Theory' and 'Criticisms and Counterproposals to the Copenhagen Interpretation', that Heisenberg delivered in 1955, are reprinted in the collection Physics and Philosophy. Before the book was released for sale, Heisenberg privately expressed regret for having used the term, due to its suggestion of the existence of other interpretations, that he considered to be "nonsense". In a 1960 review of Heisenberg's book, Bohr's close collaborator Léon Rosenfeld called the term an "ambiguous expression" and suggested it be discarded. However, this did not come to pass, and the term entered widespread use.
There is no uniquely definitive statement of the Copenhagen interpretation. The term encompasses the views developed by a number of scientists and philosophers during the second quarter of the 20th century. This lack of a single, authoritative source that establishes the Copenhagen interpretation is one difficulty with discussing it; another complication is that the philosophical background familiar to Einstein, Bohr, Heisenberg, and contemporaries is much less so to physicists and even philosophers of physics in more recent times. Bohr and Heisenberg never totally agreed on how to understand the mathematical formalism of quantum mechanics, and Bohr distanced himself from what he considered Heisenberg's more subjective interpretation. Bohr offered an interpretation that is independent of a subjective observer, or measurement, or collapse; instead, an "irreversible" or effectively irreversible process causes the decay of quantum coherence which imparts the classical behavior of "observation" or "measurement".
Different commentators and researchers have associated various ideas with the term. Asher Peres remarked that very different, sometimes opposite, views are presented as "the Copenhagen interpretation" by different authors. N. David Mermin coined the phrase "Shut up and calculate!" to summarize Copenhagen-type views, a saying often misattributed to Richard Feynman and which Mermin later found insufficiently nuanced. Mermin described the Copenhagen interpretation as coming in different "versions", "varieties", or "flavors".
Some basic principles generally accepted as part of the interpretation include the following:
Hans Primas and Roland Omnès give a more detailed breakdown that, in addition to the above, includes the following:
There are some fundamental agreements and disagreements between the views of Bohr and Heisenberg. For example, Heisenberg emphasized a sharp "cut" between the observer (or the instrument) and the system being observed, while Bohr offered an interpretation that is independent of a subjective observer or measurement or collapse, which relies on an "irreversible" or effectively irreversible process, which could take place within the quantum system.
Another issue of importance where Bohr and Heisenberg disagreed is wave–particle duality. Bohr maintained that the distinction between a wave view and a particle view was defined by a distinction between experimental setups, whereas Heisenberg held that it was defined by the possibility of viewing the mathematical formulas as referring to waves or particles. Bohr thought that a particular experimental setup would display either a wave picture or a particle picture, but not both. Heisenberg thought that every mathematical formulation was capable of both wave and particle interpretations.
A wave function is a mathematical entity that provides a probability distribution for the outcomes of each possible measurement on a system. Knowledge of the wave function together with the rules for the system's evolution in time exhausts all that can be predicted about the system's behavior. Generally, Copenhagen-type interpretations deny that the wave function provides a directly apprehensible image of an ordinary material body or a discernible component of some such, or anything more than a theoretical concept.
The Born rule is essential to the Copenhagen interpretation. Formulated by Max Born in 1926, it gives the probability that a measurement of a quantum system will yield a given result. In its simplest form, it states that the probability density of finding a particle at a given point, when measured, is proportional to the square of the magnitude of the particle's wave function at that point.
The concept of wave function collapse postulates that the wave function of a system can change suddenly and discontinuously upon measurement. Prior to a measurement, a wave function involves the various probabilities for the different potential outcomes of that measurement. But when the apparatus registers one of those outcomes, no traces of the others linger. Since Bohr did not view the wavefunction as something physical, he never talks about "collapse". Nevertheless, many physicists and philosophers associate collapse with the Copenhagen interpretation.
Heisenberg spoke of the wave function as representing available knowledge of a system, and did not use the term "collapse", but instead termed it "reduction" of the wave function to a new state representing the change in available knowledge which occurs once a particular phenomenon is registered by the apparatus.
Because they assert that the existence of an observed value depends upon the intercession of the observer, Copenhagen-type interpretations are sometimes called "subjective". This term is rejected by many Copenhagenists because the process of observation is mechanical and does not depend on the individuality of the observer. Wolfgang Pauli, for example, insisted that measurement results could be obtained and recorded by "objective registering apparatus". As Heisenberg wrote,
Of course the introduction of the observer must not be misunderstood to imply that some kind of subjective features are to be brought into the description of nature. The observer has, rather, only the function of registering decisions, i.e., processes in space and time, and it does not matter whether the observer is an apparatus or a human being; but the registration, i.e., the transition from the "possible" to the "actual," is absolutely necessary here and cannot be omitted from the interpretation of quantum theory.
In the 1970s and 1980s, the theory of decoherence helped to explain the appearance of quasi-classical realities emerging from quantum theory, but was insufficient to provide a technical explanation for the apparent wave function collapse.
In metaphysical terms, the Copenhagen interpretation views quantum mechanics as providing knowledge of phenomena, but not as pointing to 'really existing objects', which it regards as residues of ordinary intuition. This makes it an epistemic theory. This may be contrasted with Einstein's view, that physics should look for 'really existing objects', making itself an ontic theory.
The metaphysical question is sometimes asked: "Could quantum mechanics be extended by adding so-called "hidden variables" to the mathematical formalism, to convert it from an epistemic to an ontic theory?" The Copenhagen interpretation answers this with a strong 'No'. It is sometimes alleged, for example by J.S. Bell, that Einstein opposed the Copenhagen interpretation because he believed that the answer to that question of "hidden variables" was "yes". By contrast, Max Jammer writes "Einstein never proposed a hidden variable theory." Einstein explored the possibility of a hidden variable theory, and wrote a paper describing his exploration, but withdrew it from publication because he felt it was faulty.
During the 1930s and 1940s, views about quantum mechanics attributed to Bohr and emphasizing complementarity became commonplace among physicists. Textbooks of the time generally maintained the principle that the numerical value of a physical quantity is not meaningful or does not exist until it is measured. Prominent physicists associated with Copenhagen-type interpretations have included Lev Landau, Wolfgang Pauli, Rudolf Peierls, Asher Peres, Léon Rosenfeld, and Ray Streater.
Throughout much of the 20th century, the Copenhagen tradition had overwhelming acceptance among physicists. According to a very informal poll (some people voted for multiple interpretations) conducted at a quantum mechanics conference in 1997, the Copenhagen interpretation remained the most widely accepted label that physicists applied to their own views. A similar result was found in a poll conducted in 2011.
The nature of the Copenhagen interpretation is exposed by considering a number of experiments and paradoxes.
This thought experiment highlights the implications that accepting uncertainty at the microscopic level has on macroscopic objects. A cat is put in a sealed box, with its life or death made dependent on the state of a subatomic particle. Thus a description of the cat during the course of the experiment—having been entangled with the state of a subatomic particle—becomes a "blur" of "living and dead cat." But this cannot be accurate because it implies the cat is actually both dead and alive until the box is opened to check on it. But the cat, if it survives, will only remember being alive. Schrödinger resists "so naively accepting as valid a 'blurred model' for representing reality." How can the cat be both alive and dead?
In Copenhagen-type views, the wave function reflects our knowledge of the system. The wave function ( | dead ⟩ + | alive ⟩ ) / 2 {\displaystyle (|{\text{dead}}\rangle +|{\text{alive}}\rangle )/{\sqrt {2}}} means that, once the cat is observed, there is a 50% chance it will be dead, and 50% chance it will be alive. (Some versions of the Copenhagen interpretation reject the idea that a wave function can be assigned to a physical system that meets the everyday definition of "cat"; in this view, the correct quantum-mechanical description of the cat-and-particle system must include a superselection rule.)
"Wigner's friend" is a thought experiment intended to make that of Schrödinger's cat more striking by involving two conscious beings, traditionally known as Wigner and his friend. (In more recent literature, they may also be known as Alice and Bob, per the convention of describing protocols in information theory.) Wigner puts his friend in with the cat. The external observer believes the system is in state ( | dead ⟩ + | alive ⟩ ) / 2 {\displaystyle (|{\text{dead}}\rangle +|{\text{alive}}\rangle )/{\sqrt {2}}} . However, his friend is convinced that the cat is alive, i.e. for him, the cat is in the state | alive ⟩ {\displaystyle |{\text{alive}}\rangle } . How can Wigner and his friend see different wave functions?
In a Heisenbergian view, the answer depends on the positioning of Heisenberg cut, which can be placed arbitrarily (at least according to Heisenberg, though not to Bohr). If Wigner's friend is positioned on the same side of the cut as the external observer, his measurements collapse the wave function for both observers. If he is positioned on the cat's side, his interaction with the cat is not considered a measurement. Different Copenhagen-type interpretations take different positions as to whether observers can be placed on the quantum side of the cut.
In the basic version of this experiment, a light source, such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate. The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen – a result that would not be expected if light consisted of classical particles. However, the light is always found to be absorbed at the screen at discrete points, as individual particles (not waves); the interference pattern appears via the varying density of these particle hits on the screen. Furthermore, versions of the experiment that include detectors at the slits find that each detected photon passes through one slit (as would a classical particle), and not through both slits (as would a wave). Such experiments demonstrate that particles do not form the interference pattern if one detects which slit they pass through.
According to Bohr's complementarity principle, light is neither a wave nor a stream of particles. A particular experiment can demonstrate particle behavior (passing through a definite slit) or wave behavior (interference), but not both at the same time.
The same experiment has been performed for light, electrons, atoms, and molecules. The extremely small de Broglie wavelength of objects with larger mass makes experiments increasingly difficult, but in general quantum mechanics considers all matter as possessing both particle and wave behaviors.
This thought experiment involves a pair of particles prepared in what later authors would refer to as an entangled state. In a 1935 paper, Einstein, Boris Podolsky, and Nathan Rosen pointed out that, in this state, if the position of the first particle were measured, the result of measuring the position of the second particle could be predicted. If instead the momentum of the first particle were measured, then the result of measuring the momentum of the second particle could be predicted. They argued that no action taken on the first particle could instantaneously affect the other, since this would involve information being transmitted faster than light, which is forbidden by the theory of relativity. They invoked a principle, later known as the "Einstein–Podolsky–Rosen (EPR) criterion of reality", positing that, "If, without in any way disturbing a system, we can predict with certainty (i.e., with probability equal to unity) the value of a physical quantity, then there exists an element of reality corresponding to that quantity". From this, they inferred that the second particle must have a definite value of position and of momentum prior to either being measured.
Bohr's response to the EPR paper was published in the Physical Review later that same year. He argued that EPR had reasoned fallaciously. Because measurements of position and of momentum are complementary, making the choice to measure one excludes the possibility of measuring the other. Consequently, a fact deduced regarding one arrangement of laboratory apparatus could not be combined with a fact deduced by means of the other, and so, the inference of predetermined position and momentum values for the second particle was not valid. Bohr concluded that EPR's "arguments do not justify their conclusion that the quantum description turns out to be essentially incomplete."
Einstein was an early and persistent supporter of objective reality. Bohr and Heisenberg advanced the position that no physical property could be understood without an act of measurement, while Einstein refused to accept this. Abraham Pais recalled a walk with Einstein when the two discussed quantum mechanics: "Einstein suddenly stopped, turned to me and asked whether I really believed that the moon exists only when I look at it." While Einstein did not doubt that quantum mechanics was a correct physical theory in that it gave correct predictions, he maintained that it could not be a complete theory. The most famous product of his efforts to argue the incompleteness of quantum theory is the Einstein–Podolsky–Rosen thought experiment, which was intended to show that physical properties like position and momentum have values even if not measured. The argument of EPR was not generally persuasive to other physicists.
Carl Friedrich von Weizsäcker, while participating in a colloquium at Cambridge, denied that the Copenhagen interpretation asserted "What cannot be observed does not exist". Instead, he suggested that the Copenhagen interpretation follows the principle "What is observed certainly exists; about what is not observed we are still free to make suitable assumptions. We use that freedom to avoid paradoxes."
Einstein was likewise dissatisfied with the indeterminism of quantum theory. Regarding the possibility of randomness in nature, Einstein said that he was "convinced that He [God] does not throw dice." Bohr, in response, reputedly said that "it cannot be for us to tell God, how he is to run the world".
Much criticism of Copenhagen-type interpretations has focused on the need for a classical domain where observers or measuring devices can reside, and the imprecision of how the boundary between quantum and classical might be defined. This boundary came to be termed the Heisenberg cut (while John Bell derisively called it the "shifty split"). As typically portrayed, Copenhagen-type interpretations involve two different kinds of time evolution for wave functions, the deterministic flow according to the Schrödinger equation and the probabilistic jump during measurement, without a clear criterion for when each kind applies. Why should these two different processes exist, when physicists and laboratory equipment are made of the same matter as the rest of the universe? And if there is somehow a split, where should it be placed? Steven Weinberg writes that the traditional presentation gives "no way to locate the boundary between the realms in which [...] quantum mechanics does or does not apply."
The problem of thinking in terms of classical measurements of a quantum system becomes particularly acute in the field of quantum cosmology, where the quantum system is the universe. How does an observer stand outside the universe in order to measure it, and who was there to observe the universe in its earliest stages? Advocates of Copenhagen-type interpretations have disputed the seriousness of these objections. Rudolf Peierls noted that "the observer does not have to be contemporaneous with the event"; for example, we study the early universe through the cosmic microwave background, and we can apply quantum mechanics to that just as well as to any electromagnetic field. Likewise, Asher Peres argued that physicists are, conceptually, outside those degrees of freedom that cosmology studies, and applying quantum mechanics to the radius of the universe while neglecting the physicists in it is no different from quantizing the electric current in a superconductor while neglecting the atomic-level details.
You may object that there is only one universe, but likewise there is only one SQUID in my laboratory.
A large number of alternative interpretations have appeared, sharing some aspects of the Copenhagen interpretation while providing alternatives to other aspects. The ensemble interpretation is similar; it offers an interpretation of the wave function, but not for single particles. The consistent histories interpretation advertises itself as "Copenhagen done right". More recently, interpretations inspired by quantum information theory like QBism and relational quantum mechanics have appeared. Experts on quantum foundational issues continue to favor the Copenhagen interpretation over other alternatives. Physicists who have suggested that the Copenhagen tradition needs to be built upon or extended include Rudolf Haag and Anton Zeilinger.
Under realism and determinism, if the wave function is regarded as ontologically real, and collapse is entirely rejected, a many-worlds interpretation results. If wave function collapse is regarded as ontologically real as well, an objective collapse theory is obtained. Bohmian mechanics shows that it is possible to reformulate quantum mechanics to make it deterministic, at the price of making it explicitly nonlocal. It attributes not only a wave function to a physical system, but in addition a real position, that evolves deterministically under a nonlocal guiding equation. The evolution of a physical system is given at all times by the Schrödinger equation together with the guiding equation; there is never a collapse of the wave function. The transactional interpretation is also explicitly nonlocal.
Some physicists espoused views in the "Copenhagen spirit" and then went on to advocate other interpretations. For example, David Bohm and Alfred Landé both wrote textbooks that put forth ideas in the Bohr–Heisenberg tradition, and later promoted nonlocal hidden variables and an ensemble interpretation respectively. John Archibald Wheeler began his career as an "apostle of Niels Bohr"; he then supervised the PhD thesis of Hugh Everett that proposed the many-worlds interpretation. After supporting Everett's work for several years, he began to distance himself from the many-worlds interpretation in the 1970s. Late in life, he wrote that while the Copenhagen interpretation might fairly be called "the fog from the north", it "remains the best interpretation of the quantum that we have".
Other physicists, while influenced by the Copenhagen tradition, have expressed frustration at how it took the mathematical formalism of quantum theory as given, rather than trying to understand how it might arise from something more fundamental. (E. T. Jaynes described the mathematical formalism of quantum physics as "a peculiar mixture describing in part realities of Nature, in part incomplete human information about Nature—all scrambled up together by Heisenberg and Bohr into an omelette that nobody has seen how to unscramble".) This dissatisfaction has motivated new interpretative variants as well as technical work in quantum foundations. | [

Over the years, there have been many objections to aspects of Copenhagen-type interpretations, including the discontinuous and stochastic nature of the "observation" or "measurement" process, the apparent subjectivity of requiring an observer, the difficulty of defining what might count as a measuring device, and the seeming reliance upon classical physics in describing such devices. Still, including all the variations, the interpretation remains one of the most commonly taught. | 2001-08-21T23:49:15Z | 2023-11-28T03:37:53Z | [

5,864 | Customs union | A customs union is generally defined as a type of trade bloc which is composed of a free trade area with a common external tariff.
Customs unions are established through trade pacts where the participant countries set up common external trade policy (in some cases they use different import quotas). Common competition policy is also helpful to avoid competition deficiency.
Purposes for establishing a customs union normally include increasing economic efficiency and establishing closer political and cultural ties between the member countries. It is the third stage of economic integration.
Every economic union, customs and monetary union and economic and monetary union includes a customs union.
The General Agreement on Tariffs and Trade, part of the World Trade Organization framework defines a customs union in the following way:
(a) A customs union shall be understood to mean the substitution of a single customs territory for two or more customs territories, so that
(i) duties and other restrictive regulations of commerce (except, where necessary, those permitted under Articles XI, XII, XIII, XIV, XV and XX) are eliminated with respect to substantially all the trade between the constituent territories of the union or at least with respect to substantially all the trade in products originating in such territories, and,
(ii) subject to the provisions of paragraph 9, substantially the same duties and other regulations of commerce are applied by each of the members of the union to the trade of territories not included in the union;
The German Customs Union, the Zollverein, which was established in 1834, and gradually developed and expanded, was a customs union organization that appeared earlier and played a role in promoting German economic development and political unification at that time. Before the establishment of the unified German Empire in the 1870s, there were checkpoints between and within the German states, which hindered the development of industry and commerce. In 1818, Prussia took the lead in abolishing the customs duties in the mainland; it was followed by the establishment of the North German Customs Union in 1826. Two years later, two customs unions were established in the states of South Germany.
In 1834, 18 states joined together to form the German Customs Union with Prussia as the main leader. Thereafter, this alliance was further expanded to all German-speaking regions and became the All-German Customs Union. The contents of the alliance convention included: abolishing internal tariffs, unifying external tariffs, raising import tax rates, and allocating tariff income to all states in the alliance in proportion. In addition, there is a customs union between France and Monaco, which was established in 1865.
A customs union was established by Switzerland and Liechtenstein in 1924, by Belgium, the Netherlands, and Luxembourg in 1948, by the countries of the European Economic Community in 1958, and by the Economic Community of Central African States in 1964. At that time, the European Free Trade Association was different from the European Economic Community Customs Union. Free trade within the former was limited to industrial products, and no uniform tariffs were imposed on countries outside the Union.
It was brought into action by the initiative of Prussia and joined by most of the German states. Pre- modern conditions ( 30+ currencies, trade barriers etc.) were viewed as an obstacle as obstacles to o economic exchange and growth by the new commercial classes, who argued for the creation of a unified economic territory allowing the unhindered movement of goods, people and capital.
The main feature of the Customs Union is that the member countries have not only eliminated trade barriers and implemented free trade, but also established a common external tariff. In other words, in addition to agreeing to eliminate each other 's trade barriers, members of the Customs Union also adopt common external tariff and trade policies. GATT stipulates that if the customs union is not established immediately, but is gradually completed over a period of time, it should be completed within a reasonable period, which generally does not exceed 10 years.
The exclusive protection measures of the Customs Union mainly include the following:
Economic effects of customs unions can generally be grouped into static effects and dynamic effects.
There are trade creation effects and trade diversion effects. The trade creation effect refers to the benefits generated by products from domestic production with higher production costs to the production of customs union countries with lower costs. The trade diversion effect refers to the loss incurred when a product is imported from a non-member country with lower production costs to a member country with a higher cost. This is the price of joining the customs union. When the trade creation effect is greater than the transfer effect, the combined effect of joining the Customs Union on the member countries is net profit, which means an increase in the economic welfare level of the member countries; otherwise, it is a net loss and a decline in the economic welfare level.
The trade creation effect is usually regarded as a positive effect. This is because the domestic production cost of country A is higher than the production cost of country A 's imports from country B. The Customs Union made Country A give up the domestic production of some commodities and change it to Country B to produce these commodities. From a worldwide perspective, this kind of production conversion improves the efficiency of resource allocation.
The customs union will not only bring static effects to member states, but also bring some dynamic effects to them. Sometimes, this dynamic effect is more important than its static effect, which has an important impact on the economic growth of member countries.
Additionally, the autonomous and dependent territories such as some of the EU member state special territories are sometimes treated as separate customs territories from their mainland states or have varying arrangements of formal or de facto customs union, common market and currency union (or combinations thereof) with the mainland and in regards to third countries through the trade pacts signed by the mainland state.
The European Union is a customs union and therefore sets a common external tariff. | [

5,865 | Council of Europe | The Council of Europe (CoE; French: Conseil de l'Europe, CdE) is an international organisation established in the wake of World War II to uphold human rights, democracy and the rule of law in Europe. Founded in 1949, as of 2023 it brings together 46 member states, with a population of approximately 675 million; it operates with an annual budget of approximately 500 million euros.
The organisation is distinct from the European Union (EU), although people sometimes confuse the two organisations – partly because the EU has adopted the original European flag, designed for the Council of Europe in 1955, as well as the European anthem. No country has ever joined the EU without first belonging to the Council of Europe. The Council of Europe is an official United Nations Observer.
As an international organisation, the Council of Europe cannot make laws, but it does have the ability to push for the enforcement of select international agreements reached by member states on various topics. The best-known body of the Council of Europe is the European Court of Human Rights, which functions on the basis of the European Convention on Human Rights of 1953.
The council's two statutory bodies are the Committee of Ministers, which comprises the foreign ministers of each member state, and the Parliamentary Assembly of the Council of Europe (PACE), which is composed of members of the national parliaments of each member state. The Commissioner for Human Rights is an institution within the Council of Europe, mandated to promote awareness of and respect for human rights within the member states. The secretary general presides over the secretariat of the organisation. Other major CoE bodies include the European Directorate for the Quality of Medicines & HealthCare (EDQM) and the European Audiovisual Observatory.
The headquarters of the Council of Europe, as well as its Court of Human Rights, are situated in Strasbourg, France. The Council uses English and French as its two official languages. The Committee of Ministers, the PACE, and the Congress of the Council of Europe also use German and Italian for some of their work.
In a speech in 1929, French Foreign Minister Aristide Briand floated the idea of an organisation which would gather European nations together in a "federal union" to resolve common problems. The United Kingdom's wartime Prime Minister Winston Churchill first publicly suggested the creation of a "Council of Europe" in a BBC radio broadcast on 21 March 1943, while the Second World War was still raging. In his own words, he tried to "peer through the mists of the future to the end of the war", and think about how to rebuild and maintain peace on a shattered continent. Given that Europe had been at the origin of two world wars, the creation of such a body would be, he suggested, "a stupendous business". He returned to the idea during a well-known speech at the University of Zurich on 19 September 1946, throwing the full weight of his considerable post-war prestige behind it.
Additionally, there were also many other statesmen and politicians across the continent, many of them members of the European Movement, who were quietly working towards the creation of the council. Some regarded it as a guarantee that the horrors of war – or the human rights violations of the Nazi regime – could never again be visited on the continent, others came to see it as a "club of democracies", built around a set of common values that could stand as a bulwark against totalitarian states belonging to the Eastern Bloc. Others again saw it as a nascent "United States of Europe", the resonant phrase that Churchill had reached for at Zurich in 1946.
The future structure of the Council of Europe was discussed at the Congress of Europe, which brought together several hundred leading politicians, government representatives and members of civil society in The Hague, Netherlands, in 1948. Responding to the conclusions of the Congress of Europe, the Consultative Council of the Treaty of Brussels convened a Committee for the Study of European Unity, which met eight times from November 1948 to January 1949 to draw up the blueprint of a new broad-based European organisation.
There were two competing schools of thought: some favoured a classical international organisation with representatives of governments, while others preferred a political forum with parliamentarians. Both approaches were finally combined through the creation of a Committee of Ministers (in which governments were represented) and a Consultative Assembly (in which parliaments were represented), the two main bodies mentioned in the Statute of the Council of Europe. This dual intergovernmental and inter-parliamentary structure was later copied for the European Communities, NATO and OSCE.
The Council of Europe was signed into existence on 5 May 1949 by the Treaty of London, the organisation's founding Statute which set out the three basic values that should guide its work: democracy, human rights and the rule of law. It was signed in London on that day by ten states: Belgium, Denmark, France, Ireland, Italy, Luxembourg, the Netherlands, Norway, Sweden and the United Kingdom, though Turkey and Greece joined three months later. On 10 August 1949, 100 members of the council's Consultative Assembly, parliamentarians drawn from the twelve member nations, met in Strasbourg for its first plenary session, held over 18 sittings and lasting nearly a month. They debated how to reconcile and reconstruct a continent still reeling from war, yet already facing a new East–West divide, launched the radical concept of a trans-national court to protect the basic human rights of every citizen, and took the first steps in a process that would eventually lead to the creation of an offshoot organisation, the European Union.
In August 1949, Paul-Henri Spaak resigned as Belgium's foreign minister in order to be elected as the first president of the assembly. Behind the scenes, he too had been quietly working towards the creation of the council, and played a key role in steering its early work. However, in December 1951, after nearly three years in the role, Spaak resigned in disappointment after the Assembly rejected proposals for a "European political authority". Convinced that the Council of Europe was never going to be in a position to achieve his long-term goal of a unified Europe, he soon tried again in a new and more promising format, based this time on economic integration, becoming one of the founders of the European Union.
There was huge enthusiasm for the Council of Europe in its early years, as its pioneers set about drafting what was to become the European Convention on Human Rights, a charter of individual rights which – it was hoped – no member government could ever again violate. They drew, in part, on the tenets of the Universal Declaration of Human Rights, signed only a few months earlier in Paris. But crucially, where the Universal Declaration was essentially aspirational, the European Convention from the beginning featured an enforcement mechanism – an international Court – which was to adjudicate on alleged violations of its articles and to hold governments to account, a dramatic leap forward for international justice. Today, this is the European Court of Human Rights, whose rulings are binding on 46 European nations, the most far-reaching system of international justice anywhere in the world.
One of the council's first acts was to welcome West Germany into its fold on 2 May 1951, setting a pattern of post-war reconciliation that was to become a hallmark of the council, and beginning a long process of "enlargement" which was to see the organisation grow from its original ten founding member states to the 46 nations that make up the Council of Europe today. Iceland had already joined in 1950, followed in 1956 by Austria, Cyprus in 1961, Switzerland in 1963 and Malta in 1965.
In 2018, an archive of all speeches made to the PACE by heads of state or government since the Council of Europe's creation in 1949 appeared online, the fruit of a two-year project entitled "Voices of Europe". At the time of its launch, the archive comprised 263 speeches delivered over a 70-year period by some 216 presidents, prime ministers, monarchs and religious leaders from 45 countries – though it continues to expand, as new speeches are added every few months.
Some very early speeches by individuals considered to be "founding figures" of the European institutions, even if they were not heads of state or government at the time, are also included (such as Sir Winston Churchill or Robert Schuman). Addresses by eight monarchs appear in the list (such as King Juan Carlos I of Spain, King Albert II of Belgium and Grand Duke Henri of Luxembourg) as well as the speeches given by religious figures (such as Pope John Paul II, and Pope Francis) and several leaders from countries in the Middle East and North Africa (such as Shimon Peres, Yasser Arafat, Hosni Mubarak, Léopold Sédar Senghor or King Hussein of Jordan).
The full text of the speeches is given in both English and French, regardless of the original language used. The archive is searchable by country, by name, and chronologically.
Article 1(a) of the Statute states that "The aim of the Council of Europe is to achieve a greater unity between its members for the purpose of safeguarding and realising the ideals and principles which are their common heritage and facilitating their economic and social progress." Membership is open to all European states who seek harmony, cooperation, good governance and human rights, accepting the principle of the rule of law and are able and willing to guarantee democracy, fundamental human rights and freedoms.
Whereas the member states of the European Union transfer part of their national legislative and executive powers to the European Commission and the European Parliament, Council of Europe member states maintain their sovereignty but commit themselves through conventions/treaties (international law) and co-operate on the basis of common values and common political decisions. Those conventions and decisions are developed by the member states working together at the Council of Europe. Both organisations function as concentric circles around the common foundations for European cooperation and harmony, with the Council of Europe being the geographically wider circle. The European Union could be seen as the smaller circle with a much higher level of integration through the transfer of powers from the national to the EU level. "The Council of Europe and the European Union: different roles, shared values." Council of Europe conventions/treaties are also open for signature to non-member states, thus facilitating equal co-operation with countries outside Europe.
The Council of Europe's most famous achievement is the European Convention on Human Rights, which was adopted in 1950 following a report by the PACE, and followed on from the United Nations 'Universal Declaration of Human Rights' (UDHR). The Convention created the European Court of Human Rights in Strasbourg. The Court supervises compliance with the European Convention on Human Rights and thus functions as the highest European court. It is to this court that Europeans can bring cases if they believe that a member country has violated their fundamental rights and freedoms.
The various activities and achievements of the Council of Europe can be found in detail on its official website. The Council of Europe works in the following areas:
The institutions of the Council of Europe are:
The CoE system also includes a number of semi-autonomous structures known as "Partial Agreements", some of which are also open to non-member states:
Occasionally the Council of Europe organizes summits of the heads of state and government of its member states. Four summits have been held to date with the fourth concluding on 17 May 2023.
The seat of the Council of Europe is in Strasbourg, France. First meetings were held in Strasbourg's University Palace in 1949, but the Council of Europe soon moved into its own buildings. The Council of Europe's eight main buildings are situated in the Quartier européen, an area in the northeast of Strasbourg spread over the three districts of Le Wacken, La Robertsau and Quartier de l'Orangerie, where are also located the four buildings of the seat of the European Parliament in Strasbourg, the Arte headquarters and the seat of the International Institute of Human Rights.
Building in the area started in 1949 with the predecessor of the Palais de l'Europe, the House of Europe (demolished in 1977), and came to a provisional end in 2007 with the opening of the New General Office Building, later named "Agora", in 2008. The Palais de l'Europe (Palace of Europe) and the Art Nouveau Villa Schutzenberger (seat of the European Audiovisual Observatory) are in the Orangerie district, and the European Court of Human Rights, the EDQM and the Agora Building are in the Robertsau district. The Agora building has been voted "best international business centre real estate project of 2007" on 13 March 2008, at the MIPIM 2008. The European Youth Centre is located in the Wacken district.
Besides its headquarters in Strasbourg, the Council of Europe is also present in other cities and countries. The Council of Europe Development Bank has its seat in Paris, the North-South Centre of the Council of Europe is established in Lisbon, Portugal, and the Centre for Modern Languages is in Graz, Austria. There are European Youth Centres in Budapest, Hungary, and in Strasbourg. The European Wergeland Centre, a new Resource Centre on education for intercultural dialogue, human rights and democratic citizenship, operated in cooperation with the Norwegian Government, opened in Oslo, Norway, in February 2009.
The Council of Europe has external offices all over the European continent and beyond. There are four 'Programme Offices', namely in Ankara, Podgorica, Skopje, and Venice. There are also 'Council of Europe Offices' in Baku, Belgrade, Chisinau, Kyiv, Paris, Pristina, Sarajevo, Tbilisi, Tirana, and Yerevan. Bucharest has a Council of Europe Office on Cybercrime. There are also Council of Europe Offices in non-European capital cities like Rabat and Tunis.
Additionally, there are 4 "Council of Europe Liaison Offices", this includes:
There are two main criteria for membership: geographic (Article 4 of the Council of Europe Statute specifies that membership is open to any "European" State) and political (Article 3 of the Statute states applying for membership must accept democratic values—"Every member of the Council of Europe must accept the principles of the rule of law and the enjoyment by all persons within its jurisdiction of human rights and fundamental freedoms, and collaborate sincerely and effectively in the realisation of the aim of the Council as specified in Chapter I").
Since "Europe" is not defined in international law, the definition of "Europe" has been a question that has recurred during the CoE's history. Turkey was admitted in 1950, although it is a transcontinental state that lies mostly in Asia, with a smaller portion in Europe. In 1994, the PACE adopted Recommendation 1247, which said that admission to the CoE should be "in principle open only to states whose national territory lies wholly or partly in Europe"; later, however, the Assembly extended eligibility to apply and be admitted to Armenia, Azerbaijan, and Georgia.
The Council of Europe was founded on 5 May 1949 by Belgium, Denmark, France, Ireland, Italy, Luxembourg, Netherlands, Norway, Sweden and the United Kingdom. Greece and Turkey joined three months later. Iceland, West Germany and Saar Protectorate joined the Council of Europe as associate members in 1950. West Germany became a full member in 1951, and the Saar withdrew its application after it joined West Germany following the 1955 Saar Statute referendum. Joining later were Austria (1956), Cyprus (1961), Switzerland (1963), Malta (1965), and Portugal (1976). Spain joined in 1977, two years after the death of its dictator Francisco Franco and the Spanish transition to democracy. Next to join were Liechtenstein (1978), San Marino (1988) and Finland (1989). After the fall of Communism with the Revolutions of 1989 and the collapse of the Soviet Union, the following countries in Europe joined: Hungary (1990), Poland (1991), Bulgaria (1992), Estonia (1993), Lithuania (1993), Slovenia (1993), the Czech Republic (1993), Slovakia (1993), Romania (1993), Andorra (1994), Latvia (1995), Moldova (1995), Albania (1995), Ukraine (1995), the former Yugoslav Republic of Macedonia (1995) (later renamed North Macedonia), Russia (1996, expelled 2022), Croatia (1996), Georgia (1999), Armenia (2001), Azerbaijan (2001), Bosnia and Herzegovina (2002), Serbia and Montenegro (later Serbia) (2003) and Monaco (2004). The Council now has 46 member states, with Montenegro (2007) being the latest to join.
Although most Council members are predominantly Christian in heritage, there are four Muslim-majority member states: Bosnia and Herzegovina, Turkey, Albania, and Azerbaijan.
The CoE has granted some countries a status that allows them to participate in CoE activities without being full members. There are three types of nonmember status: associate member, special guest and observer. Associate member status was created for former Axis states which had not yet regained their sovereignty since their defeat in the Second World War; as such, it is no longer used, although there have been proposals to reactivate it to permit enhanced participation by the current observer states. "Special guest" status was used as a transitional status for post-Soviet countries that wished to join the council after the fall of the Berlin Wall and is no longer commonly used. "Observer" status is for non-European nations who accept democracy, rule of law, and human rights, and wish to participate in Council initiatives. The United States became an observer state in 1995. Currently, Canada, the Holy See, Japan, Mexico, and the United States are observer states, while Israel is an observer to the PACE.
The Statute of the Council of Europe provides for the voluntary suspension, involuntary suspension, and exclusion of members. Article 8 of the Statute provides that any member who has "seriously violated" Article 3 may be suspended from its rights of representation, and that the Committee of Ministers may request that such a member withdraws from the Council under Article 7. (The Statute does not define the "serious violation" phrase. Under Article 8 of the Statute, if a member state fails to withdraw upon request, the Committee may terminate its membership, in consultation with the PACE.
The Council suspended Greece in 1967, after a military coup d'état, and the Greek junta withdrew from the CoE. Greece was readmitted to the council in 1974.
Russia became a member of the Council of Europe in 1996. In 2014, after Russia annexed Crimea from Ukraine and supported separatists in eastern Ukraine, precipitating a conflict, the Council stripped Russia of its voting rights in the PACE. In response, Russia began to boycott the Assembly in 2016, and beginning from 2017 ceased paying its annual membership dues of 32.6 million euros (US$37.1 million) to the Council placing the institution under financial strain.
Russia stated that its suspension by the council was unfair, and demanded the restoration of its voting rights. Russia had threatened to withdraw from the Council unless its voting rights were restored in time for the election of a new secretary general. European Council secretary-general Thorbjørn Jagland organized a special committee to find a compromise with Russia in early 2018, a move that was criticized by some as giving in to alleged Russian pressure by Council members and academic observers, especially if voting sanctions were lifted. In June 2019, an approximately two-thirds majority of the Council voted (on a 118–62 vote, with 10 abstentions) to restore Russia's voting rights in the council. Opponents of lifting the suspension included Ukraine and other post-Soviet countries, such as the Baltic states, who argued that readmission amounted to normalizing Russia's malign activity. Supporters of restoring Russia's council rights included France and Germany, which argued that a Russian withdrawal from the council would be harmful because it would deprive Russian citizens of their ability to initiate cases in the European Court of Human Rights.
On 3 March 2022, after Russia launched a full-scale military invasion of Ukraine, the council suspended Russia for violations of the council's statute and the European Convention on Human Rights (ECHR). The suspension blocked Russia from participation in the council's ministerial council, the PACE, and the Council of the Baltic Sea States, but still left Russia obligated to follow the ECHR. On 15 March 2022, hours before the vote to expel the country, Russia initiated a voluntary withdrawal procedure from the council. The Russian delegation planned to deliver its formal withdrawal on 31 December 2022, and announced its intent to denounce the ECHR. However, on the same day, the council's Committee of Ministers decided Russia's membership in the council would be terminated immediately, and determined that Russia had been excluded from the Council instead under its exclusion mechanism rather than the withdrawal mechanism. After being excluded from the Council of Europe, Russia's former president and prime minister Dmitry Medvedev endorsed restoring the death penalty in Russia.
The Council of Europe works mainly through international treaties, usually called conventions in its system. By drafting conventions or international treaties, common legal standards are set for its member states. The conventions are collected in the European Treaty Series.
Several conventions have also been opened for signature to non-member states. Important examples are the Convention on Cybercrime (signed for example, by Canada, Japan, South Africa and the United States), the Lisbon Recognition Convention on the recognition of study periods and degrees (signed for example, by Australia, Belarus, Canada, the Holy See, Israel, Kazakhstan, Kyrgyzstan, New Zealand and the United States), the Anti-doping Convention (signed, for example, by Australia, Belarus, Canada and Tunisia) and the Convention on the Conservation of European Wildlife and Natural Habitats (signed for example, by Burkina Faso, Morocco, Tunisia and Senegal as well as the European Community). Non-member states also participate in several partial agreements, such as the Venice Commission, the Group of States Against Corruption (GRECO), the European Pharmacopoeia Commission and the North-South Centre.
Invitations to sign and ratify relevant conventions of the Council of Europe on a case-by-case basis are sent to three groups of non-member entities:
The Council of Europe is not to be confused with the Council of the European Union (the "Council of Ministers") or the European Council. These belong to the European Union, which is separate from the Council of Europe, although they have shared the same European flag and anthem since the 1980s since they both work for European integration. Nor is the Council of Europe to be confused with the European Union itself.
The Council of Europe is an entirely separate body from the European Union. It is not controlled by it.
Cooperation between the European Union and the Council of Europe was reinforced in the mid-2000s, notably on culture and education as well as on the international enforcement of justice and Human Rights.
The European Union is expected to accede to the European Convention on Human Rights (the convention). There are also concerns about consistency in case law – the European Court of Justice (the EU's court in Luxembourg) is treating the convention as part of the legal system of all EU member states in order to prevent conflict between its judgements and those of the European Court of Human Rights (the court in Strasbourg interpreting the convention). Protocol No. 14 of the convention is designed to allow the EU to accede to it and the EU Treaty of Lisbon contains a protocol binding the EU to join. The EU would thus be subject to its human rights law and external monitoring as its member states currently are.
The Council of Europe Schools of Political Studies were established to train future generations of political, economic, social and cultural leaders in countries in transition. With the participation of national and international experts, they run annual series of seminars and conferences on topics such as European integration, democracy, human rights, the rule of law and globalisation. The first School of Political Studies was created in Moscow in 1992. By 2020, 20 other schools had been set up along the same lines, forming an association; a network covering the whole of Eastern and South-Eastern Europe and the Caucasus, as well as some countries in the Southern Mediterranean region. The schools are part of the Education Department, which is part of the Directorate of Democratic Participation within the Directorate General of Democracy ("DGII") of the Council of Europe.
Cooperation between the CoE and the UN started with the agreement signed by the Secretariats of these institutions on 15 December 1951. On 17 October 1989, the General Assembly of the United Nations approved a resolution on granting observer status to the Council of Europe which was proposed by several member states of the CoE. Currently, the Council of Europe holds observer status with the United Nations and is regularly represented in the UN General Assembly. It has organised the regional UN conferences against racism and on women. It co-operates with the United Nations at many levels, in particular in the areas of human rights, minorities, migration and counter-terrorism. In November 2016, the UN General Assembly adopted by consensus Resolution (A/Res/71/17) on Cooperation between the United Nations and the Council of Europe whereby it acknowledged the contribution of the Council of Europe to the protection and strengthening of human rights and fundamental freedoms, democracy and the rule of law, welcomed the ongoing co-operation in a variety of fields.
Non-governmental organisations (NGOs) can participate in the INGOs Conference of the Council of Europe and become observers to inter-governmental committees of experts. The Council of Europe drafted the European Convention on the Recognition of the Legal Personality of International Non-Governmental Organisations in 1986, which sets the legal basis for the existence and work of NGOs in Europe. Article 11 of the European Convention on Human Rights protects the right to freedom of association, which is also a fundamental norm for NGOs. The rules for consultative status for INGOs appended to the resolution (93)38 "On relation between the Council of Europe and non-governmental organisations", adopted by the Committee of Ministers on 18 October 1993 at the 500th meeting of the Ministers' Deputies. On 19 November 2003, the Committee of Ministers changed the consultative status into a participatory status, "considering that it is indispensable that the rules governing the relations between the Council of Europe and NGOs evolve to reflect the active participation of international non-governmental organisations (INGOs) in the Organisation's policy and work programme".
On 30 May 2018, the Council of Europe signed a memorandum of understanding with the European football confederation UEFA.
The Council of Europe also signed an agreement with FIFA in which the two agreed to strengthen future cooperation in areas of common interests. The deal which included cooperation between member states in the sport of football and safety and security at football matches was finalized in October 2018.
The General Agreement on Privileges and Immunities of the Council of Europe grants the organisation certain privileges and immunities.
The working conditions of staff are governed by the council's staff regulations, which are public. Salaries and emoluments paid by the Council of Europe to its officials are tax-exempt on the basis of Article 18 of the General Agreement on Privileges and Immunities of the Council of Europe.
The Council of Europe created, and has since 1955 used as its official symbol, the European Flag with 12 golden stars arranged in a circle on a blue background.
Its musical anthem since 1972, the "European anthem", is based on the "Ode to Joy" theme from Ludwig van Beethoven's ninth symphony.
On 5 May 1964, the 15th anniversary of its founding, the Council of Europe established 5 May as Europe Day.
The wide private and public use of the European Flag is encouraged to symbolise a European dimension. To avoid confusion with the European Union which subsequently adopted the same flag in the 1980s, as well as other European institutions, the Council of Europe often uses a modified version with a lower-case "e" surrounding the stars which are referred to as the "Council of Europe Logo".
The Council of Europe has been accused of not having any meaningful purpose, being superfluous in its aims to other pan-European bodies, including the European Union and OSCE. In 2013 The Economist agreed, saying that the "Council of Europe's credibility is on the line". Both Human Rights Watch and the European Stability Initiative have called on the Council of Europe to undertake concrete actions to show that it is willing and able to return to its "original mission to protect and ensure human rights".
In October 2022, a new and different Pan-European meeting of 44 states was held, as the "inaugural summit of the European Political Community", a new forum largely organized by French President Emmanuel Macron. The Council of Europe, sidelined, reportedly was "perplexed" with this development, with a spokesperson stating "In the field of human rights, democracy and the rule of law, such a pan-European community already exists: it is the Council of Europe." A feature of the new forum is that Russia and Belarus are deliberately excluded, which was not seen as explaining the need for a different entity, given that at the time, Russia was no longer a member of the Council of Europe and Belarus only participated partially, as a non-member.
After Azerbaijan joined the CoE in 2001, both the Council and its Parliamentary Assembly were criticized for having a weak response to election rigging and human rights violations in Azerbaijan. The Human Rights Watch criticized the Council of Europe in 2014 for allowing Azerbaijan to assume the six-month rotating chairmanship of the council's Committee of Ministers, writing that the Azeri government's repression of human rights defenders, dissidents, and journalists "shows sheer contempt for its commitments to the Council of Europe". An internal inquiry was set up in 2017 amid allegations of bribery by Azerbaijan government officials and criticism of "caviar diplomacy at the Council. A 219-page report was issued in 2018 after a ten-month investigation. It concluded that several members of the Parliamentary Assembly broke CoE ethical rules and were "strongly suspected" of corruption; it strongly criticized former Parliamentary Assembly president Pedro Agramunt and suggested that he had engaged in "corruptive activities" before his resignation under pressure in 2017. The inquiry also named Italian member Luca Volontè as a suspect in "activities of a corruptive nature". Volontè was investigated by Italian police and accused by Italian prosecutors in 2017 of receiving over 2.39 million euros in bribes in exchange for working for Azerbaijan in the parliamentary assembly, and that in 2013 he played a key role in orchestrating the defeat of a highly critical report on the abuse of political prisoners in Azerbaijan. In 2021, Volontè was convicted of accepting bribes from Azerbaijani officials to water down critiques of the nation's human rights record, and he was sentenced by a court in Milan to four years in prison. | [

In his own words, he tried to \"peer through the mists of the future to the end of the war\", and think about how to rebuild and maintain peace on a shattered continent. Given that Europe had been at the origin of two world wars, the creation of such a body would be, he suggested, \"a stupendous business\".

On 10 August 1949, 100 members of the council's Consultative Assembly, parliamentarians drawn from the twelve member nations, met in Strasbourg for its first plenary session, held over 18 sittings and lasting nearly a month. They debated how to reconcile and reconstruct a continent still reeling from war, yet already facing a new East–West divide, launched the radical concept of a trans-national court to protect the basic human rights of every citizen, and took the first steps in a process that would eventually lead to the creation of an offshoot organisation, the European Union.",

But crucially, where the Universal Declaration was essentially aspirational, the European Convention from the beginning featured an enforcement mechanism – an international Court – which was to adjudicate on alleged violations of its articles and to hold governments to account, a dramatic leap forward for international justice.

European Council secretary-general Thorbjørn Jagland organized a special committee to find a compromise with Russia in early 2018, a move that was criticized by some as giving in to alleged Russian pressure by Council members and academic observers, especially if voting sanctions were lifted. In June 2019, an approximately two-thirds majority of the Council voted (on a 118–62 vote, with 10 abstentions) to restore Russia's voting rights in the council. Opponents of lifting the suspension included Ukraine and other post-Soviet countries, such as the Baltic states, who argued that readmission amounted to normalizing Russia's malign activity. Supporters of restoring Russia's council rights included France and Germany, which argued that a Russian withdrawal from the council would be harmful because it would deprive Russian citizens of their ability to initiate cases in the European Court of Human Rights.",

The suspension blocked Russia from participation in the council's ministerial council, the PACE, and the Council of the Baltic Sea States, but still left Russia obligated to follow the ECHR. On 15 March 2022, hours before the vote to expel the country, Russia initiated a voluntary withdrawal procedure from the council. The Russian delegation planned to deliver its formal withdrawal on 31 December 2022, and announced its intent to denounce the ECHR. However, on the same day, the council's Committee of Ministers decided Russia's membership in the council would be terminated immediately, and determined that Russia had been excluded from the Council instead under its exclusion mechanism rather than the withdrawal mechanism. After being excluded from the Council of Europe, Russia's former president and prime minister Dmitry Medvedev endorsed restoring the death penalty in Russia.",

Volontè was investigated by Italian police and accused by Italian prosecutors in 2017 of receiving over 2.39 million euros in bribes in exchange for working for Azerbaijan in the parliamentary assembly, and that in 2013 he played a key role in orchestrating the defeat of a highly critical report on the abuse of political prisoners in Azerbaijan.

] | The Council of Europe is an international organisation established in the wake of World War II to uphold human rights, democracy and the rule of law in Europe. Founded in 1949, as of 2023 it brings together 46 member states, with a population of approximately 675 million; it operates with an annual budget of approximately 500 million euros. The organisation is distinct from the European Union (EU), although people sometimes confuse the two organisations – partly because the EU has adopted the original European flag, designed for the Council of Europe in 1955, as well as the European anthem. No country has ever joined the EU without first belonging to the Council of Europe. The Council of Europe is an official United Nations Observer. As an international organisation, the Council of Europe cannot make laws, but it does have the ability to push for the enforcement of select international agreements reached by member states on various topics. The best-known body of the Council of Europe is the European Court of Human Rights, which functions on the basis of the European Convention on Human Rights of 1953. The council's two statutory bodies are the Committee of Ministers, which comprises the foreign ministers of each member state, and the Parliamentary Assembly of the Council of Europe (PACE), which is composed of members of the national parliaments of each member state. The Commissioner for Human Rights is an institution within the Council of Europe, mandated to promote awareness of and respect for human rights within the member states. The secretary general presides over the secretariat of the organisation. Other major CoE bodies include the European Directorate for the Quality of Medicines & HealthCare (EDQM) and the European Audiovisual Observatory. The headquarters of the Council of Europe, as well as its Court of Human Rights, are situated in Strasbourg, France. The Council uses English and French as its two official languages. The Committee of Ministers, the PACE, and the Congress of the Council of Europe also use German and Italian for some of their work. | 2001-07-25T07:33:12Z | 2023-12-27T02:16:11Z | [

5,866 | Council of the European Union | 50°50′33.00″N 4°22′50.99″E / 50.8425000°N 4.3808306°E / 50.8425000; 4.3808306
The Council of the European Union, often referred to in the treaties and other official documents simply as the Council, and informally known as the Council of Ministers, is the third of the seven Institutions of the European Union (EU) as listed in the Treaty on European Union. It is one of two legislative bodies and together with the European Parliament serves to amend and approve or veto the proposals of the European Commission, which holds the right of initiative.
The Council of the European Union and the European Council are the only EU institutions that are explicitly intergovernmental, that is, forums whose attendees express and represent the position of their Member State's executive, be they ambassadors, ministers or heads of state/government.
The Council meets in 10 different configurations of 27 national ministers (one per state). The precise membership of these configurations varies according to the topic under consideration; for example, when discussing agricultural policy the Council is formed by the 27 national ministers whose portfolio includes this policy area (with the related European Commissioners contributing but not voting).
The Presidency of the Council rotates every six months among the governments of EU member states, with the relevant ministers of the respective country holding the Presidency at any given time ensuring the smooth running of the meetings and setting the daily agenda. The continuity between presidencies is provided by an arrangement under which three successive presidencies, known as Presidency trios, share common political programmes. The Foreign Affairs Council (national foreign ministers) is however chaired by the Union's High Representative.
Its decisions are made by qualified majority voting in most areas, unanimity in others, or just simple majority for procedural issues. Usually where it operates unanimously, it only needs to consult the Parliament. However, in most areas the ordinary legislative procedure applies meaning both Council and Parliament share legislative and budgetary powers equally, meaning both have to agree for a proposal to pass. In a few limited areas the Council may initiate new EU law itself.
The General Secretariat of the Council of the European Union, also known as Council Secretariat, assists the Council of the European Union, the Presidency of the Council of the European Union, the European Council and the President of the European Council. The Secretariat is headed by the Secretary-General of the Council of the European Union. The Secretariat is divided into seven directorates-general, each administered by a director-general.
The Council first appeared in the European Coal and Steel Community (ECSC) as the "Special Council of Ministers", set up to counterbalance the High Authority (the supranational executive, now the Commission). The original Council had limited powers: issues relating only to coal and steel were in the Authority's domain, and the Council's consent was only required on decisions outside coal and steel. As a whole, the Council only scrutinised the High Authority (the executive). In 1957, the Treaties of Rome established two new communities, and with them two new Councils: the Council of the European Atomic Energy Community (EAEC) and the Council of the European Economic Community (EEC). However, due to objections over the supranational power of the Authority, their Councils had more powers; the new executive bodies were known as "Commissions".
In 1965, the Council was hit by the "empty chair crisis". Due to disagreements between French President Charles de Gaulle and the Commission's agriculture proposals, among other things, France boycotted all meetings of the Council. This halted the Council's work until the impasse was resolved the following year by the Luxembourg compromise. Although initiated by a gamble of the President of the Commission, Walter Hallstein, who later on lost the Presidency, the crisis exposed flaws in the Council's workings.
Under the Merger Treaty of 1967, the ECSC's Special Council of Ministers and the Council of the EAEC (together with their other independent institutions) were merged into the Council of the European Communities, which would act as a single Council for all three institutions. In 1993, the Council adopted the name 'Council of the European Union', following the establishment of the European Union by the Maastricht Treaty. That treaty strengthened the Council, with the addition of more intergovernmental elements in the three pillars system. However, at the same time the Parliament and Commission had been strengthened inside the Community pillar, curtailing the ability of the Council to act independently.
The Treaty of Lisbon abolished the pillar system and gave further powers to Parliament. It also merged the Council's High Representative with the Commission's foreign policy head, with this new figure chairing the foreign affairs Council rather than the rotating presidency. The European Council was declared a separate institution from the Council, also chaired by a permanent president, and the different Council configurations were mentioned in the treaties for the first time.
The development of the Council has been characterised by the rise in power of the Parliament, with which the Council has had to share its legislative powers. The Parliament has often provided opposition to the Council's wishes. This has in some cases led to clashes between both bodies with the Council's system of intergovernmentalism contradicting the developing parliamentary system and supranational principles.
The primary purpose of the Council is to act as one of two vetoing bodies of the EU's legislative branch, the other being the European Parliament. Together they serve to amend, approve or disapprove the proposals of the European Commission, which has the sole power to propose laws. Jointly with the Parliament, the Council holds the budgetary power of the Union and has greater control than the Parliament over the more intergovernmental areas of the EU, such as foreign policy and macroeconomic co-ordination. Finally, before the entry into force of the Treaty of Lisbon, it formally held the executive power of the EU which it conferred upon the European Commission. It is considered by some to be equivalent to an upper house of the EU legislature, although it is not described as such in the treaties. The Council represents the executive governments of the EU's member states and is based in the Europa building in Brussels.
The EU's legislative authority is divided between the Council, the Parliament and the Commission. As the relationships and powers of these institutions have developed, various legislative procedures have been created for adopting laws. In early times, the avis facultatif maxim was: "The Commission proposes, and the Council disposes"; but now the vast majority of laws are subject to the ordinary legislative procedure, which works on the principle that consent from both the Council and Parliament are required before a law may be adopted.
Under this procedure, the Commission presents a proposal to Parliament and the Council. Following its first reading the Parliament may propose amendments. If the Council accepts these amendments then the legislation is approved. If it does not then it adopts a "common position" and submits that new version to the Parliament. At its second reading, if the Parliament approves the text or does not act, the text is adopted, otherwise the Parliament may propose further amendments to the Council's proposal. It may be rejected out right by an absolute majority of MEPs. If the Council still does not approve the Parliament's position, then the text is taken to a "Conciliation Committee" composed of the Council members plus an equal number of MEPs. If a Committee manages to adopt a joint text, it then has to be approved in a third reading by both the Council and Parliament or the proposal is abandoned.
The few other areas that operate the special legislative procedures are justice & home affairs, budget and taxation and certain aspects of other policy areas: such as the fiscal aspects of environmental policy. In these areas, the Council or Parliament decide law alone. The procedure used also depends upon which type of institutional act is being used. The strongest act is a regulation, an act or law which is directly applicable in its entirety. Then there are directives which bind members to certain goals which they must achieve, but they do this through their own laws and hence have room to manoeuvre in deciding upon them. A decision is an instrument which is focused at a particular person or group and is directly applicable. Institutions may also issue recommendations and opinions which are merely non-binding declarations.
The Council votes in one of three ways; unanimity, simple majority, or qualified majority. In most cases, the Council votes on issues by qualified majority voting, meaning that there must be a minimum of 55% of member states agreeing (at least 15) who together represent at least 65% of the EU population. A 'blocking minority' can only be formed by at least 4 member states representing at least 35% of the EU population.
Council resolutions have no legal effect. Usually the Council's intention is to set out future work foreseen in a specific policy area or to invite action by the Commission. If a resolution covers a policy area which is not entirely within an area of EU competency, the resolution will be issued as a "resolution of the Council and the representatives of the governments of the member states". Examples are the Council Resolution of 26 September 1989 on the development of subcontracting in the Community and the Council Resolution of 26 November 2001 on consumer credit and indebtedness.
The legal instruments used by the Council for the Common Foreign and Security Policy are different from the legislative acts. Under the CFSP they consist of "common positions", "joint actions", and "common strategies". Common positions relate to defining a European foreign policy towards a particular third-country such as the promotion of human rights and democracy in Myanmar, a region such as the stabilisation efforts in the African Great Lakes, or a certain issue such as support for the International Criminal Court. A common position, once agreed, is binding on all EU states who must follow and defend the policy, which is regularly revised. A joint action refers to a co-ordinated action of the states to deploy resources to achieve an objective, for example for mine clearing or to combat the spread of small arms. Common strategies defined an objective and commits the EUs resources to that task for four years.
The legislative branch officially holds the Union's budgetary authority. The EU's budget (which is around 155 billion euro) is subject to a form of the ordinary legislative procedure with a single reading giving Parliament power over the entire budget (prior to 2009, its influence was limited to certain areas) on an equal footing with the Council. If there is a disagreement between them, it is taken to a conciliation committee as it is for legislative proposals. But if the joint conciliation text is not approved, the Parliament may adopt the budget definitively. In addition to the budget, the Council coordinates the economic policy of members.
The Council's rules of procedure contain the provisions necessary for its organisation and functioning.
The Presidency of the Council is not a single post, but is held by a member state's government. Every six months the presidency rotates among the states, in an order predefined by the Council's members, allowing each state to preside over the body. From 2007, every three member states co-operate for their combined eighteen months on a common agenda, although only one formally holds the presidency for the normal six-month period. For example, the President for the second half of 2007, Portugal, was the second in a trio of states alongside Germany and Slovenia with whom Portugal had been co-operating. The Council meets in various configurations (as outlined below) so its membership changes depending upon the issue. The person chairing the Council will always be the member from the state holding the Presidency. A delegate from the following Presidency also assists the presiding member and may take over work if requested. The exception however is the foreign affairs council, which has been chaired by the High Representative since the entry into force of the Lisbon Treaty.
The role of the Presidency is administrative and political. On the administrative side it is responsible for procedures and organising the work of the Council during its term. This includes summoning the Council for meetings along with directing the work of COREPER and other committees and working groups. The political element is the role of successfully dealing with issues and mediating in the Council. In particular this includes setting the agenda of the council, hence giving the Presidency substantial influence in the work of the Council during its term. The Presidency also plays a major role in representing the Council within the EU and representing the EU internationally, for example at the United Nations.
Legally speaking, the Council is a single entity (this means that technically any Council configuration can adopt decisions that fall within the remit of any other Council configuration) but it is in practice divided into several different council configurations (or ‘(con)formations’). Article 16(6) of the Treaty on European Union provides:
The Council shall meet in different configurations, the list of which shall be adopted in accordance with Article 236 of the Treaty on the Functioning of the European Union.
The General Affairs Council shall ensure consistency in the work of the different Council configurations. It shall prepare and ensure the follow-up to meetings of the European Council, in liaison with the President of the European Council and the Commission.
The Foreign Affairs Council shall elaborate the Union's external action on the basis of strategic guidelines laid down by the European Council and ensure that the Union's action is consistent.
Each council configuration deals with a different functional area, for example agriculture and fisheries. In this formation, the council is composed of ministers from each state government who are responsible for this area: the agriculture and fisheries ministers. The chair of this council is held by the member from the state holding the presidency (see section above). Similarly, the Economic and Financial Affairs Council is composed of national finance ministers, and they are still one per state and the chair is held by the member coming from the presiding country. The Councils meet irregularly throughout the year except for the three major configurations (top three below) which meet once a month. As of 2020, there are ten formations:
Complementing these, the Political and Security Committee (PSC) brings together ambassadors to monitor international situations and define policies within the CSDP, particularly in crises. The European Council is similar to a configuration of the Council and operates in a similar way, but is composed of the national leaders (heads of government or state) and has its own President, since 2019, Charles Michel. The body's purpose is to define the general "impetus" of the Union. The European Council deals with the major issues such as the appointment of the President of the European Commission who takes part in the body's meetings.
Ecofin's Eurozone component, the Euro group, is also a formal group with its own President. Its European Council counterpart is the Euro summit formalized in 2011 and the TSCG.
Following the entry into force of a framework agreement between the EU and ESA there is a Space Council configuration—a joint and concomitant meeting of the EU Council and of the ESA Council at ministerial level dealing with the implementation of the ESP adopted by both organisations.
The General Secretariat of the Council provides the continuous infrastructure of the Council, carrying out preparation for meetings, draft reports, translation, records, documents, agendas and assisting the presidency. The Secretary General of the Council is head of the Secretariat. The Secretariat is divided into seven directorates-general, each administered by a director-general.
The Committee of Permanent Representatives (COREPER) is a body composed of representatives from the states (ambassadors, civil servants etc.) who meet each week to prepare the work and tasks of the Council. It monitors and co-ordinates work and deals with the Parliament on co-decision legislation. It is divided into two groups of the representatives (Coreper II) and their deputies (Coreper I). Agriculture is dealt with separately by the Special Committee on Agriculture (SCA). The numerous working groups submit their reports to the Council through Coreper or SCA.
The Treaty of Lisbon mandated a change in voting system from 1 November 2014 for most cases to double majority Qualified Majority Voting, replacing the voting weights system. Decisions made by the council have to be taken by 55% of member states representing at least 65% of the EU's population.
Almost all members of the Council are members of a political party at national level, and most of these are members of a European-level political party. However the Council is composed to represent the Member States rather than political parties and the nature of coalition governments in a number of states means that party breakdown at different configuration of the Council vary depending on which domestic party was assigned the portfolio. However, the broad ideological alignment of the government in each state does influence the nature of the law the Council produces and the extent to which the link between domestic parties puts pressure on the members in the European Parliament to vote a certain way.
By a decision of the European Council at Edinburgh in December 1992, the Council has its seat in Brussels but in April, June, and October, it holds its meetings in Luxembourg City. Between 1952 and 1967, the ECSC Council held its Luxembourg City meetings in the Cercle Municipal on Place d’Armes. Its secretariat moved on numerous occasions but between 1955 and 1967 it was housed in the Verlorenkost district of the city. In 1957, with the creation of two new Communities with their own Councils, discretion on location was given to the current Presidency. In practice this was to be in the Château of Val-Duchesse until the autumn of 1958, at which point it moved to 2 Rue Ravensteinstraat in Brussels.
The 1965 agreement (finalised by the Edinburgh agreement and annexed to the treaties) on the location of the newly merged institutions, the Council was to be in Brussels but would meet in Luxembourg City during April, June, and October. The ECSC secretariat moved from Luxembourg City to the merged body Council secretariat in the Ravenstein building of Brussels. In 1971 the Council and its secretariat moved into the Charlemagne building, next to the Commission's Berlaymont, but the Council rapidly ran out of space and administrative branch of the Secretariat moved to a building at 76 Rue Joseph II/Jozef II-straat and during the 1980s the language divisions moved out into the Nerviens, Frère Orban, and Guimard buildings.
In 1995, the Council moved into the Justus Lipsius building, across the road from Charlemagne. However, its staff was still increasing, so it continued to rent the Frère Orban building to house the Finnish and Swedish language divisions. Staff continued to increase and the Council rented, in addition to owning Justus Lipsius, the Kortenberg, Froissart, Espace Rolin, and Woluwe Heights buildings. Since acquiring the Lex building in 2008, the three aforementioned buildings are no longer in use by the Council services.
When the Council is meeting in Luxembourg City, it meets in the Kirchberg Conference Centre, and its offices are based at the European Centre on the plateau du Kirchberg. The Council has also met occasionally in Strasbourg, in various other cities, and also outside the Union: for example in 1974 when it met in Tokyo and Washington, D. C. while trade and energy talks were taking place. Under the Council's present rules of procedures the Council can, in extraordinary circumstances, hold one of its meetings outside Brussels and Luxembourg.
From 2017, both the Council of the European Union and the European Council adopted the purpose built Europa building as their official headquarters, although they continue to utilise the facilities afforded by the adjacent Justus Lipsius building. The focal point of the new building, the distinctive multi-storey "lantern" shaped structure in which the main meeting room is located, is utilised in both EU institutions' new official logos. | [

5,867 | Continental Europe | Continental Europe or mainland Europe is the contiguous mainland of Europe, excluding its surrounding islands. It can also be referred to ambiguously as the European continent, – which can conversely mean the whole of Europe – and, by some, simply as the Continent. When Eurasia is regarded as a single continent, Europe is treated both as a continent and subcontinent.
The continental territory of the historical Carolingian Empire was one of the many old cultural concepts used for mainland Europe. This was consciously invoked in the 1950s as one of the basis for the prospective European integration (see also multi-speed Europe)
The most common definition of mainland Europe excludes these continental islands: the Greek islands, Cyprus, Malta, Sicily, Sardinia, Corsica, the Balearic Islands, Great Britain and Ireland and surrounding islands, Novaya Zemlya and the Nordic archipelago, as well as nearby oceanic islands, including the Canary Islands, Madeira, the Azores, Iceland, the Faroe Islands, and Svalbard.
The Scandinavian Peninsula is sometimes also excluded as, even though it is a part of "mainland Europe", the de facto connections to the rest of the continent are across the Baltic Sea or North Sea (rather than via the lengthy land route that involves travelling to the north of the peninsula where it meets Finland, and then south through northeast Europe).
In both Great Britain and Ireland, the Continent is widely and generally used to refer to the mainland of Europe. An amusing British newspaper headline supposedly once read, "Fog in Channel; Continent Cut Off". It has also been claimed that this was a regular weather forecast in Britain in the 1930s. In addition, the word Europe itself is also regularly used to mean Europe excluding the islands of Great Britain, Iceland, and Ireland (although the term is often used to refer to the European Union). The term mainland Europe is also sometimes used. Usage of these terms may reflect political or cultural allegiances, for example it has been observed that there is a correlation between whether a British citizen considers themselves "British" or "European" and whether they live in an area which primarily supported Brexit.
Derivatively, the adjective continental refers to the social practices or fashion of continental Europe. Examples include breakfast, topless sunbathing and, historically, long-range driving (before Britain had motorways) often known as Grand Touring. Differences include electrical plugs, time zones for the most part, the use of left-hand traffic, and for the United Kingdom, currency and the continued use of certain imperial units alongside the metric units which have long since displaced customary units in continental Europe.
Britain is physically connected to continental Europe through the undersea Channel Tunnel (the longest undersea tunnel in the world), which accommodates both the Eurotunnel Shuttle (passenger and vehicle use – vehicle required) and Eurostar (passenger use only) services. These services were established to transport passengers and vehicles through the tunnel on a 24/7 basis between England and continental Europe, while still maintaining passport and immigration control measures on both sides of the tunnel. This route is popular with refugees and migrants seeking to enter the UK.
Especially in Germanic studies, continental refers to the European continent excluding the Scandinavian Peninsula, Britain, Ireland, and Iceland. The reason for this is that although the Scandinavian peninsula is attached to continental Europe, and accessible via a land route along the 66th parallel north, it is usually reached by sea.
Kontinenten ("the Continent") is a vernacular Swedish expression that refers to an area excluding Sweden, Norway, and Finland but including Denmark (even the Danish Archipelago which is technically not a part of continental Europe) and the rest of continental Europe. In Norway, similarly, one speaks about Kontinentet as a separate entity. In Denmark, Jutland is referred to as the mainland and thereby a part of continental Europe.
The Scandinavian Peninsula is now connected to the Danish mainland (the Jutland Peninsula) by several bridges and tunnels.
The Continent may sometimes refer to the continental part of France (excluding Corsica and overseas France), the continental part of Greece (excluding the Aegean Islands, Crete, and the Ionian Islands), the continental part of Italy (excluding Sardinia, Sicily, etc.), the continental part of Portugal (excluding the Azores and Madeira), and the continental part of Spain (excluding the Balearic Islands, the Canary Islands, the plazas de soberanía, etc.). The term is used from the perspective of the island residents of each country to describe the continental portion of their country or the continent (or mainland) as a whole.
Continental France is also known as l'Hexagone, "the Hexagon", referring to its approximate shape on a map. Continental Spain is referred to as peninsular Spain. | [

5,869 | Category theory | Category theory is a general theory of mathematical structures and their relations that was introduced by Samuel Eilenberg and Saunders Mac Lane in the middle of the 20th century in their foundational work on algebraic topology. Category theory is used in almost all areas of mathematics. In particular, many constructions of new mathematical objects from previous ones that appear similarly in several contexts are conveniently expressed and unified in terms of categories. Examples include quotient spaces, direct products, completion, and duality.
Many areas of computer science also rely on category theory, such as functional programming and semantics.
A category is formed by two sorts of objects: the objects of the category, and the morphisms, which relate two objects called the source and the target of the morphism. One often says that a morphism is an arrow that maps its source to its target. Morphisms can be composed if the target of the first morphism equals the source of the second one, and morphism composition has similar properties as function composition (associativity and existence of identity morphisms). Morphisms are often some sort of function, but this is not always the case. For example, a monoid may be viewed as a category with a single object, whose morphisms are the elements of the monoid.
The second fundamental concept of category theory is the concept of a functor, which plays the role of a morphism between two categories C 1 {\displaystyle C_{1}} and C 2 : {\displaystyle C_{2}:} it maps objects of C 1 {\displaystyle C_{1}} to objects of C 2 {\displaystyle C_{2}} and morphisms of C 1 {\displaystyle C_{1}} to morphisms of C 2 {\displaystyle C_{2}} in such a way that sources are mapped to sources and targets are mapped to targets (or, in the case of a contravariant functor, sources are mapped to targets and vice-versa). A third fundamental concept is a natural transformation that may be viewed as a morphism of functors.
A category C consists of the following three mathematical entities:
Relations among morphisms (such as fg = h) are often depicted using commutative diagrams, with "points" (corners) representing objects and "arrows" representing morphisms.
Morphisms can have any of the following properties. A morphism f : a → b is a:
Every retraction is an epimorphism, and every section is a monomorphism. Furthermore, the following three statements are equivalent:
Functors are structure-preserving maps between categories. They can be thought of as morphisms in the category of all (small) categories.
A (covariant) functor F from a category C to a category D, written F : C → D, consists of:
such that the following two properties hold:
A contravariant functor F: C → D is like a covariant functor, except that it "turns morphisms around" ("reverses all the arrows"). More specifically, every morphism f : x → y in C must be assigned to a morphism F(f) : F(y) → F(x) in D. In other words, a contravariant functor acts as a covariant functor from the opposite category C to D.
A natural transformation is a relation between two functors. Functors often describe "natural constructions" and natural transformations then describe "natural homomorphisms" between two such constructions. Sometimes two quite different constructions yield "the same" result; this is expressed by a natural isomorphism between the two functors.
If F and G are (covariant) functors between the categories C and D, then a natural transformation η from F to G associates to every object X in C a morphism ηX : F(X) → G(X) in D such that for every morphism f : X → Y in C, we have ηY ∘ F(f) = G(f) ∘ ηX; this means that the following diagram is commutative:
The two functors F and G are called naturally isomorphic if there exists a natural transformation from F to G such that ηX is an isomorphism for every object X in C.
Using the language of category theory, many areas of mathematical study can be categorized. Categories include sets, groups and topologies.
Each category is distinguished by properties that all its objects have in common, such as the empty set or the product of two topologies, yet in the definition of a category, objects are considered atomic, i.e., we do not know whether an object A is a set, a topology, or any other abstract concept. Hence, the challenge is to define special objects without referring to the internal structure of those objects. To define the empty set without referring to elements, or the product topology without referring to open sets, one can characterize these objects in terms of their relations to other objects, as given by the morphisms of the respective categories. Thus, the task is to find universal properties that uniquely determine the objects of interest.
Numerous important constructions can be described in a purely categorical way if the category limit can be developed and dualized to yield the notion of a colimit.
It is a natural question to ask: under which conditions can two categories be considered essentially the same, in the sense that theorems about one category can readily be transformed into theorems about the other category? The major tool one employs to describe such a situation is called equivalence of categories, which is given by appropriate functors between two categories. Categorical equivalence has found numerous applications in mathematics.
The definitions of categories and functors provide only the very basics of categorical algebra; additional important topics are listed below. Although there are strong interrelations between all of these topics, the given order can be considered as a guideline for further reading.
Many of the above concepts, especially equivalence of categories, adjoint functor pairs, and functor categories, can be situated into the context of higher-dimensional categories. Briefly, if we consider a morphism between two objects as a "process taking us from one object to another", then higher-dimensional categories allow us to profitably generalize this by considering "higher-dimensional processes".
For example, a (strict) 2-category is a category together with "morphisms between morphisms", i.e., processes which allow us to transform one morphism into another. We can then "compose" these "bimorphisms" both horizontally and vertically, and we require a 2-dimensional "exchange law" to hold, relating the two composition laws. In this context, the standard example is Cat, the 2-category of all (small) categories, and in this example, bimorphisms of morphisms are simply natural transformations of morphisms in the usual sense. Another basic example is to consider a 2-category with a single object; these are essentially monoidal categories. Bicategories are a weaker notion of 2-dimensional categories in which the composition of morphisms is not strictly associative, but only associative "up to" an isomorphism.
This process can be extended for all natural numbers n, and these are called n-categories. There is even a notion of ω-category corresponding to the ordinal number ω.
Higher-dimensional categories are part of the broader mathematical field of higher-dimensional algebra, a concept introduced by Ronald Brown. For a conversational introduction to these ideas, see John Baez, 'A Tale of n-categories' (1996).
It should be observed first that the whole concept of a category is essentially an auxiliary one; our basic concepts are essentially those of a functor and of a natural transformation [...]
Whilst specific examples of functors and natural transformations had been given by Samuel Eilenberg and Saunders Mac Lane in a 1942 paper on group theory, these concepts were introduced in a more general sense, together with the additional notion of categories, in a 1945 paper by the same authors (who discussed applications of category theory to the field of algebraic topology). Their work was an important part of the transition from intuitive and geometric homology to homological algebra, Eilenberg and Mac Lane later writing that their goal was to understand natural transformations, which first required the definition of functors, then categories.
Stanislaw Ulam, and some writing on his behalf, have claimed that related ideas were current in the late 1930s in Poland. Eilenberg was Polish, and studied mathematics in Poland in the 1930s. Category theory is also, in some sense, a continuation of the work of Emmy Noether (one of Mac Lane's teachers) in formalizing abstract processes; Noether realized that understanding a type of mathematical structure requires understanding the processes that preserve that structure (homomorphisms). Eilenberg and Mac Lane introduced categories for understanding and formalizing the processes (functors) that relate topological structures to algebraic structures (topological invariants) that characterize them.
Category theory was originally introduced for the need of homological algebra, and widely extended for the need of modern algebraic geometry (scheme theory). Category theory may be viewed as an extension of universal algebra, as the latter studies algebraic structures, and the former applies to any kind of mathematical structure and studies also the relationships between structures of different nature. For this reason, it is used throughout mathematics. Applications to mathematical logic and semantics (categorical abstract machine) came later.
Certain categories called topoi (singular topos) can even serve as an alternative to axiomatic set theory as a foundation of mathematics. A topos can also be considered as a specific type of category with two additional topos axioms. These foundational applications of category theory have been worked out in fair detail as a basis for, and justification of, constructive mathematics. Topos theory is a form of abstract sheaf theory, with geometric origins, and leads to ideas such as pointless topology.
Categorical logic is now a well-defined field based on type theory for intuitionistic logics, with applications in functional programming and domain theory, where a cartesian closed category is taken as a non-syntactic description of a lambda calculus. At the very least, category theoretic language clarifies what exactly these related areas have in common (in some abstract sense).
Category theory has been applied in other fields as well. For example, John Baez has shown a link between Feynman diagrams in physics and monoidal categories. Another application of category theory, more specifically: topos theory, has been made in mathematical music theory, see for example the book The Topos of Music, Geometric Logic of Concepts, Theory, and Performance by Guerino Mazzola.
More recent efforts to introduce undergraduates to categories as a foundation for mathematics include those of William Lawvere and Rosebrugh (2003) and Lawvere and Stephen Schanuel (1997) and Mirroslav Yotov (2012). | [

5,872 | Bradycardia | Bradycardia is a medical term used to describe a resting heart rate under 60 beats per minute (BPM). While bradycardia can result from a variety of pathologic processes, it is commonly a physiologic response to cardiovascular conditioning, or due to asymptomatic type 1 atrioventricular block. Resting heart rates less than 50 BPM are often normal during sleep in young and healthy adults, and in athletes. In large population studies of adults without underlying heart disease, resting heart rates of 45-50 BPM appear to be the lower limits of normal, dependent on age and sex. Bradycardia is most likely to be discovered in the elderly, as both age and underlying cardiac disease progression contribute to its development.
Bradycardia may be associated with symptoms of fatigue, dyspnea, dizziness, confusion, and frank syncope due to reduced forward blood flow to the brain, lungs, and skeletal muscle. The types of symptoms often depend on the etiology of the slow heart rate, classified by the anatomic location of a dysfunction within the cardiac conduction system. Generally, these classifications involve the broad categories of sinus node dysfunction (SND), atrioventricular block, and other conduction tissue disease. However, bradycardia can also result without dysfunction of the native conduction system, arising secondary to medications including beta blockers, calcium channel blockers, antiarrythmics, and other cholinergic drugs. Excess vagus nerve activity or carotid sinus hypersensitivity are neurological causes of transient symptomatic bradycardia. Hypothyroidism and metabolic derangements are other common extrinsic causes of bradycardia.
The management of a bradycardia is generally reserved for patients with symptoms, regardless of minimum heart rate during sleep or the presence of concomitant heart rhythm abnormalities (See: Sinus pause), which are common with this condition. Untreated SND has been shown to increase the future risk of heart failure and syncope, sometimes warranting definitive treatment with an implanted pacemaker. In atrioventricular causes of bradycardia, permanent pacemaker implantation is often required when no reversible causes of disease are found. In both SND and atrioventricular blocks, there is little role for medical therapy unless a patient is hemodynamically unstable, which may require the use of medications such as atropine, isoproterenol, and interventions such as transcutaenous pacing, until such time that an appropriate workup can be undertaken and long term treatment selected. While asymptomatic bradycardias rarely require treatment, consultation with a physician is recommended, especially in the elderly.
The term "relative bradycardia" can refer to a heart rate lower than that expected in a particular disease state, often a febrile illness. "Chronotropic incompetence" (CI) refers to an inadequate rise in heart rate during periods of increased demand, often due to exercise, and is an important sign of SND and indication for pacemaker implantation.
The word "bradycardia" is from the Greek βραδύς bradys "slow", and καρδία kardia "heart".
The heart is a type of specialized muscle containing repeating units of cardiomyocytes, or heart muscle cells. Like most cells, cardiomyocytes maintain a highly regulated negative voltage at rest, and are capable of propagating action potentials, much like neurons. While at rest, the negative cellular voltage of a cardiomyocyte can be raised above a certain threshold (so called depolarization) by an incoming action potential, causing the myocyte to contract. When these contractions occur in a coordinated fashion, the atria and ventricles of the heart will pump, delivering blood to the rest of the body.
Normally, the origination of the action potential causing cardiomyocyte contraction originates from the sinoatrial node (SA node). This collection of specialized conduction tissue is located in the right atrium, near the entrance of the superior vena cava. The SA node contains pacemaker cells that demonstrate "automaticity" and are capable of generating impulses that travel through the heart and create a steady heart beat.
In the beginning of the cardiac cycle, the SA node generates an electrical action potential which spreads across the right and left atria, causing the atrial contraction of the cardiac cycle. This electrical impulse carries on to the atrioventricular node (AV node), another specialized grouping of cells located in the base of the right atrium, which is the only anatomically normal electrical connection between the atria and ventricles. Impulses coursing through the AV node are slowed before carrying on to the ventricles, allowing for appropriate filling of the ventricles before contraction. The SA and AV nodes are both closely regulated by fibers of the autonomic nervous system, allowing for adjustment of cardiac output by the central nervous system in times of increased metabolic demand.
Following slowed conduction through the atrioventricular node, the action potential originally produced at the SA node now flows through the His-purkinje system. The bundle of His originates in the AV node and rapidly splits into a left and right branch, each destined for a different ventricle. Finally, these bundle branches terminate in the small Purkinje fibers that innervate myocardial tissue. The His-purkinje system conducts action potentials much faster than can be propagated between myocardial cells, which allows the entire ventricular myocardium to contract in a smaller length of time, improving pump function.
Most pathological causes of bradycardia result from damage to this normal cardiac conduction system at various levels: the sinoatrial node, the atrioventricular node, or from damage to conduction tissue between or after these nodes.
Bradycardia caused by the alterations of sinus node activity is divided into three types.
Sinus is a sinus rhythm of less than 50 BPM. Cardiac action potentials are generated from the SA node, propagated through an otherwise normal conduction system, but occur at a slow rate. It is a common condition found in both healthy individuals and those considered well-conditioned athletes. Studies have found that 50–85% of conditioned athletes have benign sinus bradycardia, as compared to 23% of the general population studied. The heart muscle of athletes has a higher stroke volume, and so requires fewer contractions to circulate the same volume of blood. Asymptomatic sinus bradycardia decreases in prevalence with age.
Sinus arrhythmias are heart rhythm abnormalities characterized by variations in the cardiac cycle length in excess of 120 milliseconds (longest cycle - shortest cycle). These are the most common type of arrhythmia in the general population, and are usually without significant consequence. They typically occur in the young, athletes, or after administration of medications such as morphine. The types of sinus arrhythmia are separated into the respiratory and non-respiratory categories.
Respiratory sinus arrhythmia refers to the physiologically normal variation in heart rate due to breathing. During inspiration, vagus nerve activity decreases, reducing parasympathetic innervation of the sinoatrial node, causing an increase in heart rate. During expiration, heart rates fall due to the converse occurring.
Non-respiratory causes of sinus arrhythmia include sinus pause, sinus arrest, and sinoatrial exit block. Sinus pause and arrest involve slowing or arrest of automatic impulse generation from the sinus node. This can lead to asystole, or cardiac arrest, if ventricular escape rhythms do not engage to create backup sources of cardiac action potentials.
Sinoatrial exit block is a similar non-respiratory phenomenon of temporarily lost sinoatrial impulses. However, in contrast to a sinus pause, the action potential is still generated at the SA node, but is either unable to leave or delayed from leaving the node, preventing or delaying atrial depolariziation and subsequent ventricular systole. Therefore, the length of the pause in heart beats is usually a multiple of the P-P interval as seen on electrocardiography. Like a sinus pause, sinoatrial exit block can be symptomatic, especially with prolonged pause length.
A syndrome of intrinsic disease of the sinus node, referred to as sick sinus syndrome or sinus node dysfunction, covers conditions that include symptomatic sinus bradycardia or persistent chronotropic incompetence, sinoatrial block, sinus arrest, and tachycardia-bradycardia syndrome. These conditions can be caused by damage to the native sinus node itself, and are frequently accompanied by damaged AV node conduction and reduced backup pacemaker activity. The condition can also be caused dysfunction of the autonomic nervous system that regulates the node, and is commonly exacerbated by medications.
Bradycardia can also result to due to inhibition of the flow of action potentials through the atrioventricular (AV) node. While this can be normal in young patients due to excessive vagus nerve tone, symptomatic bradycardia due to AV node dysfunction in older people is commonly due to structural heart disease, myocardial ischemia, or age related fibrosis.
Atrioventricular blocks are divided into 3 categories, ranked by severity. AV block is diagnosed via surface ECG, which is usually sufficient to locate the causal lesion of the block, without the need of an invasive electrophysiology study.
In 1st degree AV block, electrical impulses originating in the SA node (or other ectopic focus above the ventricles) are conducted with significant delay through the AV node. This condition is diagnosed via ECG, with PR intervals in excess of 200 milliseconds. The PR interval represents the length of time between the start of atrial depolarization and start of ventricular depolarization, representing the flow of electrical impulses between the SA and AV nodes. Despite the term "block", no impulses are actually fully lost in this conduction, but are merely delayed. The location of the causal lesion can be anywhere between the AV node and the His-Purkinje system, but is most commonly found in the AV node itself. Generally, isolated PR prolongation in 1st degree AV block is not associated with increased mortality or hospitalization.
2nd degree AV block is characterized by intermittently lost conduction of impulses between the SA node and the ventricles. 2nd degree block, is classified into two types. Mobitz type 1 block, otherwise known by the eponym Wenckebach, classically demonstrates grouped patterns of heart beats on ECG. Over the course of the group, the PR interval gradually lengthens, until there is a dropped conduction, resulting in no QRS complex seen on surface ECG following the last P wave. After a delay, the grouping repeats, with the PR interval shortening again to baseline. Type 1 2nd degree AV block due to disease in the AV node (as opposed to in the His-purkinje system) rarely needs intervention with pacemaker implantation.
2nd degree, Mobitz type 2 AV block is another phenomenon of intermittently dropped QRS complexes after characteristic groupings of beats seen on surface ECG. In this condition, the PR and RR intervals are consistent, followed by a sudden AV block and dropped QRS complex. Because type 2 blocks are typically due to lesions below the AV node, the ability for ventricular escape rhythms to maintain cardiac output is compromised. Permanent pacemaker implantation is often required.
An AV-junctional rhythm, or atrioventricular nodal bradycardia, is usually caused by the absence of the electrical impulse from the sinus node. This usually appears on an electrocardiogram with a normal QRS complex accompanied with an inverted P wave either before, during, or after the QRS complex.
An AV-junctional escape beat is a delayed heartbeat originating from an ectopic focus somewhere in the AV junction. It occurs when the rate of depolarization of the SA node falls below the rate of the AV node. This dysrhythmia also may occur when the electrical impulses from the SA node fail to reach the AV node because of SA or AV block. This is a protective mechanism for the heart to compensate for an SA node that is no longer handling the pacemaking activity and is one of a series of backup sites that can take over pacemaker function when the SA node fails to do so. This would present with a longer PR interval. An AV-junctional escape complex is a normal response that may result from excessive vagal tone on the SA node. Pathological causes include sinus bradycardia, sinus arrest, sinus exit block, or AV block.
Idioventricular rhythm, also known as atrioventricular bradycardia or ventricular escape rhythm, is a heart rate of less than 50 BPM. This is a safety mechanism when a lack of electrical impulse or stimuli from the atrium occurs. Impulses originating within or below the bundle of His in the AV node will produce a wide QRS complex with heart rates between 20 and 40 BPM. Those above the bundle of His, also known as junctional, will typically range between 40 and 60 BPM with a narrow QRS complex. In a third-degree heart block, about 61% take place at the bundle branch-Purkinje system, 21% at the AV node, and 15% at the bundle of His. AV block may be ruled out with an ECG indicating "a 1:1 relationship between P waves and QRS complexes." Ventricular bradycardias occurs with sinus bradycardia, sinus arrest, and AV block. Treatment often consists of the administration of atropine and cardiac pacing.
For infants, bradycardia is defined as a heart rate less than 100 BPM (normal is around 120–160 BPM). Premature babies are more likely than full-term babies to have apnea and bradycardia spells; their cause is not clearly understood. The spells may be related to centers inside the brain that regulate breathing which may not be fully developed. Touching the baby gently or rocking the incubator slightly will almost always get the baby to start breathing again, which increasing the heart rate. Neonatal intensive-care unit standard practice is to electronically monitor the heart and lungs.
Bradycardia arrhythmia may have many causes, both cardiac and non-cardiac.
Non-cardiac causes are usually secondary, and can involve recreational drug use or abuse, metabolic or endocrine issues, especially hypothyroidism, an electrolyte imbalance, neurological factors, autonomic reflexes, situational factors, such as prolonged bed rest, and autoimmunity. At rest, although tachycardia is more commonly seen in fatty acid oxidation disorders, more rarely acute bradycardia can occur.
Cardiac causes include acute or chronic ischemic heart disease, vascular heart disease, valvular heart disease, or degenerative primary electrical disease. Ultimately, the causes act by three mechanisms: depressed automaticity of the heart, conduction block, or escape pacemakers and rhythms.
In general, two types of problems result in bradycardias: disorders of the SA node, and disorders of the AV node.
With SA node dysfunction (sometimes called sick sinus syndrome), there may be disordered automaticity or impaired conduction of the impulse from the SA node into the surrounding atrial tissue (an "exit block"). Second-degree sinoatrial blocks can be detected only by use of a 12-lead ECG. It is difficult and sometimes impossible to assign a mechanism to any particular bradycardia, but the underlying mechanism is not clinically relevant to treatment, which is the same in both cases of sick sinus syndrome: a permanent pacemaker.
AV conduction disturbances (AV block; primary AV block, secondary type I AV block, secondary type II AV block, tertiary AV block) may result from impaired conduction in the AV node, or anywhere below it, such as in the bundle of His. The clinical relevance pertaining to AV blocks is greater than that of SA blocks.
Beta blocker medicines also can slow the heart rate and decrease how forcefully the heart contracts. Beta-blockers may slow the heart rate to a dangerous level if prescribed with calcium channel blocker-type medications. Bradycardia is also part of the mammalian diving reflex.
A diagnosis of bradycardia in adults is based on a heart rate less than 60 BPM, although some studies use a heart rate of less than 50 BPM. This is determined usually either by palpation or ECG. If symptoms occur, a determination of electrolytes may be helpful in determining the underlying cause.
The treatment of bradycardia is dependent on whether or not the person is stable or unstable.
Emergency treatment is not needed if the person is asymptomatic or minimally symptomatic.
If a person is unstable, the initial recommended treatment is intravenous atropine. Doses less than 0.5 mg should not be used, as this may further decrease the rate. If this is not effective, intravenous inotrope infusion (dopamine, epinephrine) or transcutaneous pacing should be used. Transvenous pacing may be required if the cause of the bradycardia is not rapidly reversible.
In children, giving oxygen, supporting their breathing, and chest compressions are recommended.
In clinical practice, elderly people over age 65 and young athletes of both sexes may have sinus bradycardia. The US Centers for Disease Control and Prevention reported in 2011 that 15.2% of adult males and 6.9% of adult females had clinically-defined bradycardia (a resting pulse rate below 60 BPM). | [

] | Bradycardia is a medical term used to describe a resting heart rate under 60 beats per minute (BPM). While bradycardia can result from a variety of pathologic processes, it is commonly a physiologic response to cardiovascular conditioning, or due to asymptomatic type 1 atrioventricular block. Resting heart rates less than 50 BPM are often normal during sleep in young and healthy adults, and in athletes. In large population studies of adults without underlying heart disease, resting heart rates of 45-50 BPM appear to be the lower limits of normal, dependent on age and sex. Bradycardia is most likely to be discovered in the elderly, as both age and underlying cardiac disease progression contribute to its development. Bradycardia may be associated with symptoms of fatigue, dyspnea, dizziness, confusion, and frank syncope due to reduced forward blood flow to the brain, lungs, and skeletal muscle. The types of symptoms often depend on the etiology of the slow heart rate, classified by the anatomic location of a dysfunction within the cardiac conduction system. Generally, these classifications involve the broad categories of sinus node dysfunction (SND), atrioventricular block, and other conduction tissue disease. However, bradycardia can also result without dysfunction of the native conduction system, arising secondary to medications including beta blockers, calcium channel blockers, antiarrythmics, and other cholinergic drugs. Excess vagus nerve activity or carotid sinus hypersensitivity are neurological causes of transient symptomatic bradycardia. Hypothyroidism and metabolic derangements are other common extrinsic causes of bradycardia. The management of a bradycardia is generally reserved for patients with symptoms, regardless of minimum heart rate during sleep or the presence of concomitant heart rhythm abnormalities, which are common with this condition. Untreated SND has been shown to increase the future risk of heart failure and syncope, sometimes warranting definitive treatment with an implanted pacemaker. In atrioventricular causes of bradycardia, permanent pacemaker implantation is often required when no reversible causes of disease are found. In both SND and atrioventricular blocks, there is little role for medical therapy unless a patient is hemodynamically unstable, which may require the use of medications such as atropine, isoproterenol, and interventions such as transcutaenous pacing, until such time that an appropriate workup can be undertaken and long term treatment selected. While asymptomatic bradycardias rarely require treatment, consultation with a physician is recommended, especially in the elderly. The term "relative bradycardia" can refer to a heart rate lower than that expected in a particular disease state, often a febrile illness. "Chronotropic incompetence" (CI) refers to an inadequate rise in heart rate during periods of increased demand, often due to exercise, and is an important sign of SND and indication for pacemaker implantation. The word "bradycardia" is from the Greek βραδύς bradys "slow", and καρδία kardia "heart". | 2001-07-25T21:44:54Z | 2023-12-17T22:14:23Z | [

5,873 | Canada Day | Canada Day (French: Fête du Canada, [faɛ̯t dzy kanadɑ]), formerly known as Dominion Day (French: Fête du Dominion), is the national day of Canada. A federal statutory holiday, it celebrates the anniversary of Canadian Confederation which occurred on July 1, 1867, with the passing of the British North America Act, 1867, when the three separate colonies of the United Canadas, Nova Scotia, and New Brunswick were united into a single dominion within the British Empire called Canada.
Originally called Dominion Day (French: Le Jour de la Confédération), the holiday was renamed in 1982, the same year that the Canadian constitution was patriated by the Canada Act, 1982, which severed the vestiges of legal dependence on the Parliament of the United Kingdom. Canada Day celebrations take place throughout the country, as well as in various locations around the world attended by Canadians living abroad.
Canada Day is often informally referred to as "Canada's birthday", particularly in the popular press. However, the term "birthday" can be seen as an oversimplification, as Canada Day is the anniversary of only one important national milestone on the way to the country's full sovereignty, namely the joining on July 1, 1867, of the colonies of Canada (divided into Ontario and Quebec), Nova Scotia, and New Brunswick into a wider British federation of four provinces. Canada became a "kingdom in its own right" within the British Empire, commonly known as the Dominion of Canada.
Although a British dominion, Canada gained an increased level of political control and governance over its own affairs, the British parliament and cabinet maintaining political control over certain areas, such as foreign affairs, national defence, and constitutional changes. Canada gradually gained increasing sovereignty over the years—notably with the passage of the Statute of Westminster in 1931—until finally becoming completely sovereign with the passing of the Constitution Act, 1982, which served to fully patriate the Canadian constitution.
Under the federal Holidays Act, Canada Day is observed on July 1, unless that date falls on a Sunday, in which case July 2 is the statutory holiday. Celebratory events will generally still take place on July 1, even though it is not the legal holiday. If it falls on a weekend, businesses normally closed that day will usually dedicate the following Monday as a day off.
The enactment of the British North America Act, 1867 (today called the Constitution Act, 1867), which confederated Canada, was celebrated on July 1, 1867, with the ringing of the bells at the Cathedral Church of St James in Toronto and "bonfires, fireworks, and illuminations, excursions, military displays, and musical and other entertainments", as described in contemporary accounts. On June 20 of the following year, Governor General the Viscount Monck issued a royal proclamation asking for Canadians to celebrate the anniversary of Confederation, However, the holiday was not established statutorily until May 15, 1879, when it was designated as Dominion Day, alluding to the reference in the British North America Act to the country as a dominion. The holiday was initially not dominant in the national calendar; any celebrations were mounted by local communities and the governor general hosted a party at Rideau Hall. No larger celebrations were held until 1917, and then none again for a further decade—the gold and diamond anniversaries of Confederation, respectively.
In 1946, Philéas Côté, a Quebec member of the House of Commons, introduced a private member's bill to rename Dominion Day as Canada Day. The bill was passed quickly by the lower chamber but was stalled by the Senate, which returned it to the commons with the recommendation that the holiday be renamed The National Holiday of Canada, an amendment that effectively killed the bill.
The Canadian government began in 1958 to orchestrate Dominion Day celebrations. That year, then-Prime Minister John Diefenbaker requested that Secretary of State Ellen Fairclough organize appropriate events, with a budget of $14,000. Parliament was traditionally in session on July 1, but Fairclough persuaded Diefenbaker and the rest of the federal cabinet to attend. Official celebrations thereafter consisted usually of trooping the colour ceremonies on Parliament Hill in the afternoon and evening, followed by a mass band concert and fireworks display. Fairclough, who became Minister of Citizenship and Immigration, later expanded the bills to include performing folk and ethnic groups. The day also became more casual and family oriented.
Canada's centennial in 1967 is often seen as an important milestone in the history of Canadian nationalism and in Canada's maturing as a distinct, independent country, after which Dominion Day became more popular with average Canadians. Into the late 1960s, nationally televised, multi-cultural concerts held in Ottawa were added and the fête became known as Festival Canada. After 1980, the Canadian government began to promote celebrating Dominion Day beyond the national capital, giving grants and aid to cities across the country to help fund local activities.
Some Canadians were, by the early 1980s, informally referring to the holiday as Canada Day, a practice that caused some controversy: Proponents argued that the name Dominion Day was a holdover from the colonial era—an argument given some impetus by the patriation of the Canadian constitution in 1982—and others asserted that an alternative was needed as the term does not translate well into French. Conversely, numerous politicians, journalists, and authors, such as Robertson Davies, decried the change at the time and some continue to maintain that it was illegitimate and an unnecessary break with tradition. Others claimed dominion was widely misunderstood and conservatively inclined commenters saw the change as part of a much larger attempt by Liberals to "re-brand" or re-define Canadian history. Columnist Andrew Cohen called Canada Day a term of "crushing banality" and criticized it as "a renunciation of the past [and] a misreading of history, laden with political correctness and historical ignorance".
The holiday was officially renamed as a result of a private member's bill that was passed through the House of Commons on July 9, 1982, two years after its first reading. Only 12 members of parliament were present when the bill was taken up again, 8 fewer than the necessary quorum; however, according to parliamentary rules, the quorum is enforceable only at the start of a sitting or when a member calls attention to it. The group passed the bill in five minutes, without debate, inspiring "grumblings about the underhandedness of the process". It met with stronger resistance in the Senate. Ernest Manning argued that the rationale for the change was based on a misperception of the name and George McIlraith did not agree with the manner in which the bill was passed, urging the government to proceed in a more "dignified way". However, the Senate did eventually pass the bill, regardless. With the granting of royal assent, the holiday's name was officially changed to Canada Day on October 27, 1982, and first celebrated under that name July 1, 1983.
As the anniversary of Confederation, Dominion Day, and later Canada Day, was the date set for a number of important events, such as the first national radio network hookup by the Canadian National Railway (1927); the inauguration of the Canadian Broadcasting Corporation's cross-country television broadcast, with Governor General Vincent Massey's Dominion Day speech from Parliament Hill (1958); the flooding of the Saint Lawrence Seaway (1958); the first colour television transmission in Canada (1966); the inauguration of the Order of Canada (1967); and the establishment of "O Canada" as the country's national anthem (1980). During the Canada's sesquicentennial in 2017, the Bank of Canada released a commemorative $10 banknote, which was expected to be broadly available by Canada Day.
The COVID-19 pandemic led to the cancellation in 2020 of all in-person Canada Day festivities nationwide, due to social distancing and restrictions on public gatherings. Some were converted to virtual events. The same cancellations occurred the following year; though, some also for political reasons. In-person festivities in Ottawa returned in 2022, being re-located from Parliament Hill to LeBreton Flats due to construction associated with the Parliament Hill Rehabilitation project.
Other events fell on the same day coincidentally, such as the first day of the Battle of the Somme in 1916—shortly after which Newfoundland recognized July 1 as Memorial Day to commemorate the Newfoundland Regiment's heavy losses during the battle—and the enactment of the Chinese Immigration Act in 1923, leading Chinese-Canadians to refer to July 1 as Humiliation Day (Chinese: 僑恥日; pinyin: Qiáo Chǐ Rì) and boycott Dominion Day celebrations with shop closures, flying the Canadian flag on half-mast, or hanging wreaths in front of home and shop entrances until the act was repealed in 1947. Canada Day also coincides with Quebec's Moving Day, when many fixed-lease apartment rental terms expire. The bill changing the province's moving day from May 1 to July 1 was introduced by a federalist member of the Quebec National Assembly, Jérôme Choquette, in 1973, in order not to affect children still in school in the month of May.
Most communities across the country host organized celebrations for Canada Day, typically outdoor public events, such as parades, carnivals, festivals, barbecues, air and maritime shows, fireworks, and free musical concerts, as well as citizenship ceremonies. There is no standard mode of celebration for Canada Day; Jennifer Welsh, a professor of International Relations at the University of Oxford, said about this: "Canada Day, like the country, is endlessly decentralized. There doesn't seem to be a central recipe for how to celebrate it—chalk it up to the nature of the federation."
In the national capital of Ottawa, concerts and cultural displays are held on the front lawn of Parliament Hill, as organized by Canadian Heritage, which include the main "noon show" and an evening programme. The event traditionally begins with the singing of "God Save the King" and "O Canada" in English and French followed by a flyover by the Snowbirds. Typically the governor general and prime minister officiate, though the monarch or another member of the royal family may also attend or take the governor general's place. Smaller events are mounted in other parks around the city and in neighbouring Gatineau, Quebec. In provincial capitals, official celebrations are often held at the provincial legislative building, usually in the presence of the lieutenant-governor and/or premier of the province.
Canadian expatriates will often organize Canada Day activities in their local area on or near the date of the holiday. Examples include Canada D'eh, an annual celebration that takes place on June 30 at Lan Kwai Fong, in Hong Kong; Canadian Forces' events on bases in Afghanistan; at Trafalgar Square outside Canada House in London, England; in Mexico, at the Royal Canadian Legion in Chapala, and at the Canadian Club in Ajijic. In China, Canada Day celebrations are held at the Bund Beach by the Canadian Chamber of Commerce in Shanghai and at Canadian International School in Beijing, sponsored by the Canada China Business Council.
Given the federal nature of the anniversary, celebrating Canada Day can be a cause of friction in the province of Quebec, where the holiday is overshadowed by the province's Saint-Jean-Baptiste Day (Fête nationale), on June 24. For example, the federal government funds Canada Day events at the Old Port of Montreal—an area run by a federal Crown corporation—while the Fête nationale parade is a grassroots effort that has faced difficulties in operating due to limited funding from the federal government and a lack of corporate sponsors.
Canada Day has attracted a negative stigma among some indigenous peoples in Canada and their allies, who feel that it is a celebration of the colonization of indigenous land. Criticism of Canada Day celebrations were particularly prominent during Canada's sesquicentennial in 2017, with allegations that the commemorations downplayed the role of indigenous peoples in the country's history and the hardships they face in the present day.
The same grievances were aired four years later, after possible unmarked graves of indigenous children were found in late-June 2021, at the site of an Indian residential school in British Columbia. If not already cancelled or modified due to restrictions related to the COVID-19 pandemic, Canada Day festivities were cancelled in various communities in British Columbia, New Brunswick, and Northern Saskatchewan, while indigenous protest group Idle No More announced its intent to organize peaceful rallies in multiple major cities. Some politicians supported the cancellations, while others expressed concern that activists were attacking "the very idea of Canada itself" and hampering progress toward reconciliation. | [

5,874 | Claudine (book series) | The Claudine series consists of four early novels by French authors Colette and Henry Gauthier-Villars, published 1900–1904. Written in diary form, they describe the growth to maturity of a young girl, Claudine. Aged fifteen at the beginning of the first book, Claudine at School, the series describes her education and experiences as she grows up. All the books are written in first-person with the first three having Claudine herself as the narrator. The last in the series, Claudine s'en va, introduces a new narrator, Annie.
The novels were written in the late 19th century in collaboration with Colette's first husband, the writer Henry Gauthier-Villars, better known by his pen name "Willy". There has been much speculation over the degree of involvement of both Colette and Willy in the writing of the Claudine novels, particularly as Willy was known for often using ghostwriters. Consequently, although the novels were originally attributed to Willy only and published under his name alone, they were later published under both names. After the death of Willy, Colette went to court to challenge her former husband's involvement in any of the writing, and subsequently had his name removed from the books. This decision however was overturned after her death, as Willy's son from a prior relationship, Jacques Gauthier-Villars, successfully sued to have his father's name restored.
The Claudine novels are thought to be roughly autobiographical. | [

5,876 | Coronary artery disease | Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), myocardial ischemia, or simply heart disease, involves the reduction of blood flow to the heart muscle due to build-up of atherosclerotic plaque in the arteries of the heart. It is the most common of the cardiovascular diseases. Types include stable angina, unstable angina, and myocardial infarction. A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Occasionally it may feel like heartburn. Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and improve with rest. Shortness of breath may also occur and sometimes no symptoms are present. In many cases, the first sign is a heart attack. Other complications include heart failure or an abnormal heartbeat.
Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, depression, and excessive alcohol consumption. A number of tests may help with diagnoses including: electrocardiogram, cardiac stress testing, coronary computed tomographic angiography, and coronary angiogram, among others.
Ways to reduce CAD risk include eating a healthy diet, regularly exercising, maintaining a healthy weight, and not smoking. Medications for diabetes, high cholesterol, or high blood pressure are sometimes used. There is limited evidence for screening people who are at low risk and do not have symptoms. Treatment involves the same measures as prevention. Additional medications such as antiplatelets (including aspirin), beta blockers, or nitroglycerin may be recommended. Procedures such as percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) may be used in severe disease. In those with stable CAD it is unclear if PCI or CABG in addition to the other treatments improves life expectancy or decreases heart attack risk.
In 2015, CAD affected 110 million people and resulted in 8.9 million deaths. It makes up 15.6% of all deaths, making it the most common cause of death globally. The risk of death from CAD for a given age decreased between 1980 and 2010, especially in developed countries. The number of cases of CAD for a given age also decreased between 1990 and 2010. In the United States in 2010, about 20% of those over 65 had CAD, while it was present in 7% of those 45 to 64, and 1.3% of those 18 to 45; rates were higher among males than females of a given age.
The most common symptom is chest pain or discomfort that occurs regularly with activity, after eating, or at other predictable times; this phenomenon is termed stable angina and is associated with narrowing of the arteries of the heart. Angina also includes chest tightness, heaviness, pressure, numbness, fullness, or squeezing. Angina that changes in intensity, character or frequency is termed unstable. Unstable angina may precede myocardial infarction. In adults who go to the emergency department with an unclear cause of pain, about 30% have pain due to coronary artery disease. Angina, shortness of breath, sweating, nausea or vomiting, and lightheadedness are signs of a heart attack, or myocardial infarction, and immediate emergency medical services are crucial.
With advanced disease, the narrowing of coronary arteries reduces the supply of oxygen-rich blood flowing to the heart, which becomes more pronounced during strenuous activities during which the heart beats faster. For some, this causes severe symptoms, while others experience no symptoms at all.
Symptoms in females can differ from those in males, and the most common symptom reported by females of all races is shortness of breath. Other symptoms more commonly reported by females than males are extreme fatigue, sleep disturbances, indigestion, and anxiety. However, some females do experience irregular heartbeat, dizziness, sweating, and nausea. Burning, pain, or pressure in the chest or upper abdomen that can travel to the arm or jaw can also be experienced in females, but it is less commonly reported by females than males. On average, females experience symptoms 10 years later than males. females are less likely to recognize symptoms and seek treatment.
Coronary artery disease is characterized by heart problems that result from atherosclerosis. Atherosclerosis is a type of arteriosclerosis which is the "chronic inflammation of the arteries which causes them to harden and accumulate cholesterol plaques (atheromatous plaques) on the artery walls". CAD has a number of well determined risk factors that contribute to atherosclerosis. These risk factors for CAD include "smoking, diabetes, high blood pressure (hypertension), abnormal (high) amounts of cholesterol and other fat in the blood (dyslipidemia), type 2 diabetes and being overweight or obese (having excess body fat)" due to lack of exercise and a poor diet. Some other risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, depression, family history, psychological stress and excessive alcohol. About half of cases are linked to genetics. Smoking and obesity are associated with about 36% and 20% of cases, respectively. Smoking just one cigarette per day about doubles the risk of CAD. Lack of exercise has been linked to 7–12% of cases. Exposure to the herbicide Agent Orange may increase risk. Rheumatologic diseases such as rheumatoid arthritis, systemic lupus erythematosus, psoriasis, and psoriatic arthritis are independent risk factors as well.
Job stress appears to play a minor role accounting for about 3% of cases. In one study, females who were free of stress from work life saw an increase in the diameter of their blood vessels, leading to decreased progression of atherosclerosis. In contrast, females who had high levels of work-related stress experienced a decrease in the diameter of their blood vessels and significantly increased disease progression. Having a type A behavior pattern, a group of personality characteristics including time urgency, competitiveness, hostility, and impatience, is linked to an increased risk of coronary disease.
The consumption of different types of fats including trans unsaturated, saturated and trans in a diet "influences the level of cholesterol that is present in the bloodstream". Unsaturated fats originate from plant sources (such as oils). There are two types of unsaturated fats, cis and trans isomers. Cis unsaturated fats are bent in molecular structure and trans are linear in structure. Saturated fats originate from animal sources (such as animal fats) and are also molecularly linear in structure. The linear configurations of unsaturated trans and saturated fats allow them to easily accumulate and stack at the arterial walls when consumed in high amounts (and other positive measures towards physical health are not met).
High levels of cholesterol in the bloodstream lead to atherosclerosis. With increased levels of LDL in the bloodstream, "LDL particles will form deposits and accumulate within the arterial walls, which will lead to the development of plaques, restricting blood flow". The resultant reduction in the heart's blood supply due to atherosclerosis in coronary arteries "causes shortness of breath, angina pectoris (chest pains that are usually relieved by rest), and potentially fatal heart attacks (myocardial infarctions)".
The heritability of coronary artery disease has been estimated between 40% and 60%. Genome-wide association studies have identified over 160 genetic susceptibility loci for coronary artery disease.
Transcripts associated with CAD (TRACs) - FoxP1, ICOSLG, IKZF4/Eos, SMYD3, TRIM28, and TCF3/E2A that are likely markers of regulatory T cells (Treg), consistent with known reductions in Tregs in CAD.
The RNA changes are mostly related to ciliary and endocytic transcripts, which in the circulating immune system would be related to the immune synapse. The immune synapse is the contact-dependent mode of communication between T cells and B cells, on one side, and a variety of antigen-presenting and immunomodulating cells on the other side. One of the most differentially expressed genes, fibromodulin (FMOD, increased 2.8-fold in CAD). Several other regulated transcripts encode for proteins related to the structure and function of the immune synapse. Nebulette, the most down-regulated transcript (2.4-fold), is an important 'cytolinker' that connects actin and desmin to facilitate cytoskeletal function and vesicular movement. The endocytic pathway is further modulated by changes in tubulin, which is a key microtubule protein, and fidgetin, which is a tubulin-severing enzyme that is a GWAS marker for cardiovascular risk. Protein recycling would be modulated by changes in the proteasomal regulator SIAH3, and the ubiquitin ligase MARCHF10. On the ciliary aspect of the immune synapse, several of the modulated transcripts are related to ciliary length and function. Steriocilin (STRC) has been studied principally in outer sensory hair cells, and mutations lead to deafness. Steriocilin is a partner to mesothelin (MSN), a related super-helical protein, whose transcript is also modulated in CAD. Likewise, DCDC2, a double-cortin protein, is a known modulator of ciliary length. In the signaling pathways of the immune synapse, there were numerous transcripts that related directly to T cell function and the control of differentiation. Butyrophilin (BTN1A1) is a known co-regulator for T cell activation. Fibromodulin is a well-known modulator of the TGF-beta signaling pathway, which is a primary determinant of Tre differentiation. Further impact on the TGF-beta pathway is reflected in concurrent changes in the BMP receptor 1B RNA (BMPR1B), because the bone morphogenic proteins are members of the TGF-beta superfamily, and likewise impact Treg differentiation. As noted, several of the transcripts (TMEM98, NRCAM, SFRP5, SHISA2) are known elements of the Wnt signaling pathway, which is major determinant of Treg differentiation.
Limitation of blood flow to the heart causes ischemia (cell starvation secondary to a lack of oxygen) of the heart's muscle cells. The heart's muscle cells may die from lack of oxygen and this is called a myocardial infarction (commonly referred to as a heart attack). It leads to damage, death, and eventual scarring of the heart muscle without regrowth of heart muscle cells. Chronic high-grade narrowing of the coronary arteries can induce transient ischemia which leads to the induction of a ventricular arrhythmia, which may terminate into a dangerous heart rhythm known as ventricular fibrillation, which often leads to death.
Typically, coronary artery disease occurs when part of the smooth, elastic lining inside a coronary artery (the arteries that supply blood to the heart muscle) develops atherosclerosis. With atherosclerosis, the artery's lining becomes hardened, stiffened, and accumulates deposits of calcium, fatty lipids, and abnormal inflammatory cells – to form a plaque. Calcium phosphate (hydroxyapatite) deposits in the muscular layer of the blood vessels appear to play a significant role in stiffening the arteries and inducing the early phase of coronary arteriosclerosis. This can be seen in a so-called metastatic mechanism of calciphylaxis as it occurs in chronic kidney disease and hemodialysis. Although these people have kidney dysfunction, almost fifty percent of them die due to coronary artery disease. Plaques can be thought of as large "pimples" that protrude into the channel of an artery, causing partial obstruction to blood flow. People with coronary artery disease might have just one or two plaques, or might have dozens distributed throughout their coronary arteries. A more severe form is chronic total occlusion (CTO) when a coronary artery is completely obstructed for more than 3 months.
Microvascular angina is a type of angina pectoris in which chest pain and chest discomfort occur without signs of blockages in the larger coronary arteries of their hearts when an angiogram (coronary angiogram) is being performed. The exact cause of microvascular angina is unknown. Explanations include microvascular dysfunction or epicardial atherosclerosis. For reasons that are not well understood, females are more likely than males to have it; however, hormones and other risk factors unique to females may play a role.
For symptomatic people, stress echocardiography can be used to make a diagnosis for obstructive coronary artery disease. The use of echocardiography, stress cardiac imaging, and/or advanced non-invasive imaging is not recommended on individuals who are exhibiting no symptoms and are otherwise at low risk for developing coronary disease.
The diagnosis of microvascular angina (previously known as cardiac syndrome X – the rare coronary artery disease that is more common in females, as mentioned, is a diagnosis of exclusion. Therefore, usually, the same tests are used as in any person with the suspected of having coronary artery disease:
The diagnosis of coronary disease underlying particular symptoms depends largely on the nature of the symptoms. The first investigation is an electrocardiogram (ECG/EKG), both for stable angina and acute coronary syndrome. An X-ray of the chest and blood tests may be performed.
Stable angina is the most common form of ischemic heart disease, and is associated with reduced quality of life and increased mortality. It is caused by epicardial coronary stenosis which results in reduced blood flow and oxygen supply to the myocardium. Stable angina is characterized as short-term chest pain during physical exertion caused by an imbalance between myocardial oxygen supply and metabolic oxygen demand. Various forms of cardiac stress tests may be used to induce both symptoms and detect changes by way of electrocardiography (using an ECG), echocardiography (using ultrasound of the heart) or scintigraphy (using uptake of radionuclide by the heart muscle). If part of the heart seems to receive an insufficient blood supply, coronary angiography may be used to identify stenosis of the coronary arteries and suitability for angioplasty or bypass surgery.
In minor to moderate cases, nitroglycerine may be used to alleviate acute symptoms of stable angina or may be used immediately prior to exertion to prevent the onset of angina. Sublingual nitroglycerine is most commonly used to provide rapid relief for acute angina attacks and as a complement to anti-anginal treatments in patients with refractory and recurrent angina. When nitroglycerine enters the bloodstream, it forms free radical nitric oxide, or NO, which activates guanylate cyclase and in turn stimulates the release of cyclic GMP. This molecular signaling stimulates smooth muscle relaxation, ultimately resulting in vasodilation and consequently improved blood flow to regions of the heart affected by atherosclerotic plaque.
Stable coronary artery disease (SCAD) is also often called stable ischemic heart disease (SIHD). A 2015 monograph explains that "Regardless of the nomenclature, stable angina is the chief manifestation of SIHD or SCAD." There are U.S. and European clinical practice guidelines for SIHD/SCAD.
Diagnosis of acute coronary syndrome generally takes place in the emergency department, where ECGs may be performed sequentially to identify "evolving changes" (indicating ongoing damage to the heart muscle). Diagnosis is clear-cut if ECGs show elevation of the "ST segment", which in the context of severe typical chest pain is strongly indicative of an acute myocardial infarction (MI); this is termed a STEMI (ST-elevation MI) and is treated as an emergency with either urgent coronary angiography and percutaneous coronary intervention (angioplasty with or without stent insertion) or with thrombolysis ("clot buster" medication), whichever is available. In the absence of ST-segment elevation, heart damage is detected by cardiac markers (blood tests that identify heart muscle damage). If there is evidence of damage (infarction), the chest pain is attributed to a "non-ST elevation MI" (NSTEMI). If there is no evidence of damage, the term "unstable angina" is used. This process usually necessitates hospital admission and close observation on a coronary care unit for possible complications (such as cardiac arrhythmias – irregularities in the heart rate). Depending on the risk assessment, stress testing or angiography may be used to identify and treat coronary artery disease in patients who have had an NSTEMI or unstable angina.
There are various risk assessment systems for determining the risk of coronary artery disease, with various emphasis on different variables above. A notable example is Framingham Score, used in the Framingham Heart Study. It is mainly based on age, gender, diabetes, total cholesterol, HDL cholesterol, tobacco smoking, and systolic blood pressure. When it comes to predicting risk in younger adults (18–39 years old), Framingham Risk Score remains below 10-12% for all deciles of baseline-predicted risk.
Polygenic score is another way of risk assessment. In one study the relative risk of incident coronary events was 91% higher among participants at high genetic risk than among those at low genetic risk.
Up to 90% of cardiovascular disease may be preventable if established risk factors are avoided. Prevention involves adequate physical exercise, decreasing obesity, treating high blood pressure, eating a healthy diet, decreasing cholesterol levels, and stopping smoking. Medications and exercise are roughly equally effective. High levels of physical activity reduce the risk of coronary artery disease by about 25%. Life's Essential 8 are the key measures for improving and maintaining cardiovascular health, as defined by the American Heart Association. AHA added sleep as a factor influencing heart health in 2022.
Most guidelines recommend combining these preventive strategies. A 2015 Cochrane Review found some evidence that counseling and education to bring about behavioral change might help in high-risk groups. However, there was insufficient evidence to show an effect on mortality or actual cardiovascular events.
In diabetes mellitus, there is little evidence that very tight blood sugar control improves cardiac risk although improved sugar control appears to decrease other problems such as kidney failure and blindness.
A diet high in fruits and vegetables decreases the risk of cardiovascular disease and death. Vegetarians have a lower risk of heart disease, possibly due to their greater consumption of fruits and vegetables. Evidence also suggests that the Mediterranean diet and a high fiber diet lower the risk.
The consumption of trans fat (commonly found in hydrogenated products such as margarine) has been shown to cause a precursor to atherosclerosis and increase the risk of coronary artery disease.
Evidence does not support a beneficial role for omega-3 fatty acid supplementation in preventing cardiovascular disease (including myocardial infarction and sudden cardiac death). There is tentative evidence that intake of menaquinone (Vitamin K2), but not phylloquinone (Vitamin K1), may reduce the risk of CAD mortality.
Secondary prevention is preventing further sequelae of already established disease. Effective lifestyle changes include:
Aerobic exercise, like walking, jogging, or swimming, can reduce the risk of mortality from coronary artery disease. Aerobic exercise can help decrease blood pressure and the amount of blood cholesterol (LDL) over time. It also increases HDL cholesterol.
Although exercise is beneficial, it is unclear whether doctors should spend time counseling patients to exercise. The U.S. Preventive Services Task Force found "insufficient evidence" to recommend that doctors counsel patients on exercise but "it did not review the evidence for the effectiveness of physical activity to reduce chronic disease, morbidity, and mortality", only the effectiveness of counseling itself. The American Heart Association, based on a non-systematic review, recommends that doctors counsel patients on exercise.
Psychological symptoms are common in people with CHD, and while many psychological treatments may be offered following cardiac events, there is no evidence that they change mortality, the risk of revascularization procedures, or the rate of non-fatal myocardial infarction.
Antibiotics for secondary prevention of coronary heart disease
Antibiotics may help patients with coronary disease to reduce the risk of heart attacks and strokes. However, the latest evidence suggests that antibiotics for secondary prevention of coronary heart disease are harmful with increased mortality and occurrence of stroke. So, the use of antibiotics is not currently supported for preventing secondary coronary heart disease.
A thorough systematic review found that indeed there is a link between a CHD condition and brain dysfunction in females. Consequently, since research is showing that cardiovascular diseases, like CHD, can play a role as a precursor for dementia, like Alzheimer's disease, individuals with CHD should have a neuropsychological assessment.
There are a number of treatment options for coronary artery disease:
It is recommended that blood pressure typically be reduced to less than 140/90 mmHg. The diastolic blood pressure however should not be lower than 60 mmHg. Beta blockers are recommended first line for this use.
In those with no previous history of heart disease, aspirin decreases the risk of a myocardial infarction but does not change the overall risk of death. Aspirin therapy to prevent heart disease is thus recommended only in adults who are at increased risk for cardiovascular events, which may include postmenopausal females, males above 40, and younger people with risk factors for coronary heart disease, including high blood pressure, a family history of heart disease, or diabetes. The benefits outweigh the harms most favorably in people at high risk for a cardiovascular event, where high risk is defined as at least a 3% chance over a five-year period, but others with lower risk may still find the potential benefits worth the associated risks.
Clopidogrel plus aspirin (dual anti-platelet therapy) reduces cardiovascular events more than aspirin alone in those with a STEMI. In others at high risk but not having an acute event, the evidence is weak. Specifically, its use does not change the risk of death in this group. In those who have had a stent, more than 12 months of clopidogrel plus aspirin does not affect the risk of death.
Revascularization for acute coronary syndrome has a mortality benefit. Percutaneous revascularization for stable ischaemic heart disease does not appear to have benefits over medical therapy alone. In those with disease in more than one artery, coronary artery bypass grafts appear better than percutaneous coronary interventions. Newer "anaortic" or no-touch off-pump coronary artery revascularization techniques have shown reduced postoperative stroke rates comparable to percutaneous coronary intervention. Hybrid coronary revascularization has also been shown to be a safe and feasible procedure that may offer some advantages over conventional CABG though it is more expensive.
As of 2010, CAD was the leading cause of death globally resulting in over 7 million deaths. This increased from 5.2 million deaths from CAD worldwide in 1990. It may affect individuals at any age but becomes dramatically more common at progressively older ages, with approximately a tripling with each decade of life. Males are affected more often than females.
It is estimated that 60% of the world's cardiovascular disease burden will occur in the South Asian subcontinent despite only accounting for 20% of the world's population. This may be secondary to a combination of genetic predisposition and environmental factors. Organizations such as the Indian Heart Association are working with the World Heart Federation to raise awareness about this issue.
Coronary artery disease is the leading cause of death for both males and females and accounts for approximately 600,000 deaths in the United States every year. According to present trends in the United States, half of healthy 40-year-old males will develop CAD in the future, and one in three healthy 40-year-old females. It is the most common reason for death of males and females over 20 years of age in the United States.
After analysing data from 2 111 882 patients, the recent meta-analysis revealed that the incidence of coronary artery diseases in breast cancer survicors was 4.29 (95% CI 3.09-5.94) per 1000 person-years.
Other terms sometimes used for this condition are "hardening of the arteries" and "narrowing of the arteries". In Latin it is known as morbus ischaemicus cordis (MIC).
The Infarct Combat Project (ICP) is an international nonprofit organization founded in 1998 which tries to decrease ischemic heart diseases through education and research.
In 2016 research into the archives of the Sugar Association, the trade association for the sugar industry in the US, had sponsored an influential literature review published in 1965 in the New England Journal of Medicine that downplayed early findings about the role of a diet heavy in sugar in the development of CAD and emphasized the role of fat; that review influenced decades of research funding and guidance on healthy eating.
Research efforts are focused on new angiogenic treatment modalities and various (adult) stem-cell therapies. A region on chromosome 17 was confined to families with multiple cases of myocardial infarction. Other genome-wide studies have identified a firm risk variant on chromosome 9 (9p21.3). However, these and other loci are found in intergenic segments and need further research in understanding how the phenotype is affected.
A more controversial link is that between Chlamydophila pneumoniae infection and atherosclerosis. While this intracellular organism has been demonstrated in atherosclerotic plaques, evidence is inconclusive as to whether it can be considered a causative factor. Treatment with antibiotics in patients with proven atherosclerosis has not demonstrated a decreased risk of heart attacks or other coronary vascular diseases.
Myeloperoxidase has been proposed as a biomarker.
Plant-based nutrition has been suggested as a way to reverse coronary artery disease, but strong evidence is still lacking for claims of potential benefits.
Several immunosuppressive drugs targeting the chronic inflammation in coronary artery disease have been tested. | [

Likewise, DCDC2, a double-cortin protein, is a known modulator of ciliary length. In the signaling pathways of the immune synapse, there were numerous transcripts that related directly to T cell function and the control of differentiation. Butyrophilin (BTN1A1) is a known co-regulator for T cell activation. Fibromodulin is a well-known modulator of the TGF-beta signaling pathway, which is a primary determinant of Tre differentiation. Further impact on the TGF-beta pathway is reflected in concurrent changes in the BMP receptor 1B RNA (BMPR1B), because the bone morphogenic proteins are members of the TGF-beta superfamily, and likewise impact Treg differentiation. As noted, several of the transcripts (TMEM98, NRCAM, SFRP5, SHISA2) are known elements of the Wnt signaling pathway, which is major determinant of Treg differentiation.",

The heart's muscle cells may die from lack of oxygen and this is called a myocardial infarction (commonly referred to as a heart attack). It leads to damage, death, and eventual scarring of the heart muscle without regrowth of heart muscle cells. Chronic high-grade narrowing of the coronary arteries can induce transient ischemia which leads to the induction of a ventricular arrhythmia, which may terminate into a dangerous heart rhythm known as ventricular fibrillation, which often leads to death.",

"text": "Typically, coronary artery disease occurs when part of the smooth, elastic lining inside a coronary artery (the arteries that supply blood to the heart muscle) develops atherosclerosis. With atherosclerosis, the artery's lining becomes hardened, stiffened, and accumulates deposits of calcium, fatty lipids, and abnormal inflammatory cells – to form a plaque. Calcium phosphate (hydroxyapatite) deposits in the muscular layer of the blood vessels appear to play a significant role in stiffening the arteries and inducing the early phase of coronary arteriosclerosis. This can be seen in a so-called metastatic mechanism of calciphylaxis as it occurs in chronic kidney disease and hemodialysis. Although these people have kidney dysfunction, almost fifty percent of them die due to coronary artery disease. Plaques can be thought of as large \"pimples\" that protrude into the channel of an artery, causing partial obstruction to blood flow. People with coronary artery disease might have just one or two plaques, or might have dozens distributed throughout their coronary arteries. A more severe form is chronic total occlusion (CTO) when a coronary artery is completely obstructed for more than 3 months.",

] | Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), myocardial ischemia, or simply heart disease, involves the reduction of blood flow to the heart muscle due to build-up of atherosclerotic plaque in the arteries of the heart. It is the most common of the cardiovascular diseases. Types include stable angina, unstable angina, and myocardial infarction. A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Occasionally it may feel like heartburn. Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and improve with rest. Shortness of breath may also occur and sometimes no symptoms are present. In many cases, the first sign is a heart attack. Other complications include heart failure or an abnormal heartbeat. Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, depression, and excessive alcohol consumption. A number of tests may help with diagnoses including: electrocardiogram, cardiac stress testing, coronary computed tomographic angiography, and coronary angiogram, among others. Ways to reduce CAD risk include eating a healthy diet, regularly exercising, maintaining a healthy weight, and not smoking. Medications for diabetes, high cholesterol, or high blood pressure are sometimes used. There is limited evidence for screening people who are at low risk and do not have symptoms. Treatment involves the same measures as prevention. Additional medications such as antiplatelets, beta blockers, or nitroglycerin may be recommended. Procedures such as percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) may be used in severe disease. In those with stable CAD it is unclear if PCI or CABG in addition to the other treatments improves life expectancy or decreases heart attack risk. In 2015, CAD affected 110 million people and resulted in 8.9 million deaths. It makes up 15.6% of all deaths, making it the most common cause of death globally. The risk of death from CAD for a given age decreased between 1980 and 2010, especially in developed countries. The number of cases of CAD for a given age also decreased between 1990 and 2010. In the United States in 2010, about 20% of those over 65 had CAD, while it was present in 7% of those 45 to 64, and 1.3% of those 18 to 45; rates were higher among males than females of a given age. | 2001-07-26T10:34:20Z | 2023-12-19T10:13:04Z | [

5,879 | Caesium | Caesium (IUPAC spelling; cesium in American English) is a chemical element; it has symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegative element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite. Caesium-137, a fission product, is extracted from waste produced by nuclear reactors. It has the largest atomic radius of all elements whose radii have been measured or calculated, at about 260 picometers.
The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications for caesium were as a "getter" in vacuum tubes and in photoelectric cells. In 1967, acting on Einstein's proof that the speed of light is the most-constant dimension in the universe, the International System of Units used two specific wave counts from an emission spectrum of caesium-133 to co-define the second and the metre. Since then, caesium has been widely used in highly accurate atomic clocks.
Since the 1990s, the largest application of the element has been as caesium formate for drilling fluids, but it has a range of applications in the production of electricity, in electronics, and in chemistry. The radioactive isotope caesium-137 has a half-life of about 30 years and is used in medical applications, industrial gauges, and hydrology. Nonradioactive caesium compounds are only mildly toxic, but the pure metal's tendency to react explosively with water means that caesium is considered a hazardous material, and the radioisotopes present a significant health and environmental hazard.
Of all elements that are solid at room temperature, caesium is the softest: it has a hardness of 0.2 Mohs. It is a very ductile, pale metal, which darkens in the presence of trace amounts of oxygen. When in the presence of mineral oil (where it is best kept during transport), it loses its metallic lustre and takes on a duller, grey appearance. It has a melting point of 28.5 °C (83.3 °F), making it one of the few elemental metals that are liquid near room temperature. Mercury is the only stable elemental metal with a known melting point lower than caesium. In addition, the metal has a rather low boiling point, 641 °C (1,186 °F), the lowest of all metals other than mercury. Its compounds burn with a blue or violet colour.
Caesium forms alloys with the other alkali metals, gold, and mercury (amalgams). At temperatures below 650 °C (1,202 °F), it does not alloy with cobalt, iron, molybdenum, nickel, platinum, tantalum, or tungsten. It forms well-defined intermetallic compounds with antimony, gallium, indium, and thorium, which are photosensitive. It mixes with all the other alkali metals (except lithium); the alloy with a molar distribution of 41% caesium, 47% potassium, and 12% sodium has the lowest melting point of any known metal alloy, at −78 °C (−108 °F). A few amalgams have been studied: CsHg2 is black with a purple metallic lustre, while CsHg is golden-coloured, also with a metallic lustre.
The golden colour of caesium comes from the decreasing frequency of light required to excite electrons of the alkali metals as the group is descended. For lithium through rubidium this frequency is in the ultraviolet, but for caesium it enters the blue–violet end of the spectrum; in other words, the plasmonic frequency of the alkali metals becomes lower from lithium to caesium. Thus caesium transmits and partially absorbs violet light preferentially while other colours (having lower frequency) are reflected; hence it appears yellowish.
Caesium metal is highly reactive and pyrophoric. It ignites spontaneously in air, and reacts explosively with water even at low temperatures, more so than the other alkali metals. It reacts with ice at temperatures as low as −116 °C (−177 °F). Because of this high reactivity, caesium metal is classified as a hazardous material. It is stored and shipped in dry, saturated hydrocarbons such as mineral oil. It can be handled only under inert gas, such as argon. However, a caesium-water explosion is often less powerful than a sodium-water explosion with a similar amount of sodium. This is because caesium explodes instantly upon contact with water, leaving little time for hydrogen to accumulate. Caesium can be stored in vacuum-sealed borosilicate glass ampoules. In quantities of more than about 100 grams (3.5 oz), caesium is shipped in hermetically sealed, stainless steel containers.
The chemistry of caesium is similar to that of other alkali metals, in particular rubidium, the element above caesium in the periodic table. As expected for an alkali metal, the only common oxidation state is +1. Some slight differences arise from the fact that it has a higher atomic mass and is more electropositive than other (nonradioactive) alkali metals. Caesium is the most electropositive chemical element. The caesium ion is also larger and less "hard" than those of the lighter alkali metals.
Most caesium compounds contain the element as the cation Cs, which binds ionically to a wide variety of anions. One noteworthy exception is the caeside anion (Cs), and others are the several suboxides (see section on oxides below). More recently, caesium is predicted to behave as a p-block element and capable of forming higher fluorides with higher oxidation states (i.e., CsFn with n > 1) under high pressure. This prediction needs to be validated by further experiments.
Salts of Cs are usually colourless unless the anion itself is coloured. Many of the simple salts are hygroscopic, but less so than the corresponding salts of lighter alkali metals. The phosphate, acetate, carbonate, halides, oxide, nitrate, and sulfate salts are water-soluble. Its double salts are often less soluble, and the low solubility of caesium aluminium sulfate is exploited in refining Cs from ores. The double salts with antimony (such as CsSbCl4), bismuth, cadmium, copper, iron, and lead are also poorly soluble.
Caesium hydroxide (CsOH) is hygroscopic and strongly basic. It rapidly etches the surface of semiconductors such as silicon. CsOH has been previously regarded by chemists as the "strongest base", reflecting the relatively weak attraction between the large Cs ion and OH; it is indeed the strongest Arrhenius base; however, a number of compounds such as n-butyllithium, sodium amide, sodium hydride, caesium hydride, etc., which cannot be dissolved in water as reacting violently with it but rather only used in some anhydrous polar aprotic solvents, are far more basic on the basis of the Brønsted–Lowry acid–base theory.
A stoichiometric mixture of caesium and gold will react to form yellow caesium auride (CsAu) upon heating. The auride anion here behaves as a pseudohalogen. The compound reacts violently with water, yielding caesium hydroxide, metallic gold, and hydrogen gas; in liquid ammonia it can be reacted with a caesium-specific ion exchange resin to produce tetramethylammonium auride. The analogous platinum compound, red caesium platinide (Cs2Pt), contains the platinide ion that behaves as a pseudochalcogen.
Like all metal cations, Cs forms complexes with Lewis bases in solution. Because of its large size, Cs usually adopts coordination numbers greater than 6, the number typical for the smaller alkali metal cations. This difference is apparent in the 8-coordination of CsCl. This high coordination number and softness (tendency to form covalent bonds) are properties exploited in separating Cs from other cations in the remediation of nuclear wastes, where Cs must be separated from large amounts of nonradioactive K.
Caesium fluoride (CsF) is a hygroscopic white solid that is widely used in organofluorine chemistry as a source of fluoride anions. Caesium fluoride has the halite structure, which means that the Cs and F pack in a cubic closest packed array as do Na and Cl in sodium chloride. Notably, caesium and fluorine have the lowest and highest electronegativities, respectively, among all the known elements.
Caesium chloride (CsCl) crystallizes in the simple cubic crystal system. Also called the "caesium chloride structure", this structural motif is composed of a primitive cubic lattice with a two-atom basis, each with an eightfold coordination; the chloride atoms lie upon the lattice points at the edges of the cube, while the caesium atoms lie in the holes in the centre of the cubes. This structure is shared with CsBr and CsI, and many other compounds that do not contain Cs. In contrast, most other alkaline halides have the sodium chloride (NaCl) structure. The CsCl structure is preferred because Cs has an ionic radius of 174 pm and Cl 181 pm.
More so than the other alkali metals, caesium forms numerous binary compounds with oxygen. When caesium burns in air, the superoxide CsO2 is the main product. The "normal" caesium oxide (Cs2O) forms yellow-orange hexagonal crystals, and is the only oxide of the anti-CdCl2 type. It vaporizes at 250 °C (482 °F), and decomposes to caesium metal and the peroxide Cs2O2 at temperatures above 400 °C (752 °F). In addition to the superoxide and the ozonide CsO3, several brightly coloured suboxides have also been studied. These include Cs7O, Cs4O, Cs11O3, Cs3O (dark-green), CsO, Cs3O2, as well as Cs7O2. The latter may be heated in a vacuum to generate Cs2O. Binary compounds with sulfur, selenium, and tellurium also exist.
Caesium has 40 known isotopes, ranging in mass number (i.e. number of nucleons in the nucleus) from 112 to 151. Several of these are synthesized from lighter elements by the slow neutron capture process (S-process) inside old stars and by the R-process in supernova explosions. The only stable caesium isotope is Cs, with 78 neutrons. Although it has a large nuclear spin (7/2+), nuclear magnetic resonance studies can use this isotope at a resonating frequency of 11.7 MHz.
The radioactive Cs has a very long half-life of about 2.3 million years, the longest of all radioactive isotopes of caesium. Cs and Cs have half-lives of 30 and two years, respectively. Cs decomposes to a short-lived Ba by beta decay, and then to nonradioactive barium, while Cs transforms into Ba directly. The isotopes with mass numbers of 129, 131, 132 and 136, have half-lives between a day and two weeks, while most of the other isotopes have half-lives from a few seconds to fractions of a second. At least 21 metastable nuclear isomers exist. Other than Cs (with a half-life of just under 3 hours), all are very unstable and decay with half-lives of a few minutes or less.
The isotope Cs is one of the long-lived fission products of uranium produced in nuclear reactors. However, this fission product yield is reduced in most reactors because the predecessor, Xe, is a potent neutron poison and frequently transmutes to stable Xe before it can decay to Cs.
The beta decay from Cs to Ba results in gamma radiation as the Ba relaxes to ground state Ba, with the emitted photons having an energy of 0.6617 MeV. Cs and Sr are the principal medium-lived products of nuclear fission, and the prime sources of radioactivity from spent nuclear fuel after several years of cooling, lasting several hundred years. Those two isotopes are the largest source of residual radioactivity in the area of the Chernobyl disaster. Because of the low capture rate, disposing of Cs through neutron capture is not feasible and the only current solution is to allow it to decay over time.
Almost all caesium produced from nuclear fission comes from the beta decay of originally more neutron-rich fission products, passing through various isotopes of iodine and xenon. Because iodine and xenon are volatile and can diffuse through nuclear fuel or air, radioactive caesium is often created far from the original site of fission. With nuclear weapons testing in the 1950s through the 1980s, Cs was released into the atmosphere and returned to the surface of the earth as a component of radioactive fallout. It is a ready marker of the movement of soil and sediment from those times.
Caesium is a relatively rare element, estimated to average 3 parts per million in the Earth's crust. It is the 45th most abundant element and the 36th among the metals. Nevertheless, it is more abundant than such elements as antimony, cadmium, tin, and tungsten, and two orders of magnitude more abundant than mercury and silver; it is 3.3% as abundant as rubidium, with which it is closely associated, chemically.
Due to its large ionic radius, caesium is one of the "incompatible elements". During magma crystallization, caesium is concentrated in the liquid phase and crystallizes last. Therefore, the largest deposits of caesium are zone pegmatite ore bodies formed by this enrichment process. Because caesium does not substitute for potassium as readily as rubidium does, the alkali evaporite minerals sylvite (KCl) and carnallite (KMgCl3·6H2O) may contain only 0.002% caesium. Consequently, caesium is found in few minerals. Percentage amounts of caesium may be found in beryl (Be3Al2(SiO3)6) and avogadrite ((K,Cs)BF4), up to 15 wt% Cs2O in the closely related mineral pezzottaite (Cs(Be2Li)Al2Si6O18), up to 8.4 wt% Cs2O in the rare mineral londonite ((Cs,K)Al4Be4(B,Be)12O28), and less in the more widespread rhodizite. The only economically important ore for caesium is pollucite Cs(AlSi2O6), which is found in a few places around the world in zoned pegmatites, associated with the more commercially important lithium minerals, lepidolite and petalite. Within the pegmatites, the large grain size and the strong separation of the minerals results in high-grade ore for mining.
The world's most significant and richest known source of caesium is the Tanco Mine at Bernic Lake in Manitoba, Canada, estimated to contain 350,000 metric tons of pollucite ore, representing more than two-thirds of the world's reserve base. Although the stoichiometric content of caesium in pollucite is 42.6%, pure pollucite samples from this deposit contain only about 34% caesium, while the average content is 24 wt%. Commercial pollucite contains more than 19% caesium. The Bikita pegmatite deposit in Zimbabwe is mined for its petalite, but it also contains a significant amount of pollucite. Another notable source of pollucite is in the Karibib Desert, Namibia. At the present rate of world mine production of 5 to 10 metric tons per year, reserves will last for thousands of years.
Mining and refining pollucite ore is a selective process and is conducted on a smaller scale than for most other metals. The ore is crushed, hand-sorted, but not usually concentrated, and then ground. Caesium is then extracted from pollucite primarily by three methods: acid digestion, alkaline decomposition, and direct reduction.
In the acid digestion, the silicate pollucite rock is dissolved with strong acids, such as hydrochloric (HCl), sulfuric (H2SO4), hydrobromic (HBr), or hydrofluoric (HF) acids. With hydrochloric acid, a mixture of soluble chlorides is produced, and the insoluble chloride double salts of caesium are precipitated as caesium antimony chloride (Cs4SbCl7), caesium iodine chloride (Cs2ICl), or caesium hexachlorocerate (Cs2(CeCl6)). After separation, the pure precipitated double salt is decomposed, and pure CsCl is precipitated by evaporating the water.
The sulfuric acid method yields the insoluble double salt directly as caesium alum (CsAl(SO4)2·12H2O). The aluminium sulfate component is converted to insoluble aluminium oxide by roasting the alum with carbon, and the resulting product is leached with water to yield a Cs2SO4 solution.
Roasting pollucite with calcium carbonate and calcium chloride yields insoluble calcium silicates and soluble caesium chloride. Leaching with water or dilute ammonia (NH4OH) yields a dilute chloride (CsCl) solution. This solution can be evaporated to produce caesium chloride or transformed into caesium alum or caesium carbonate. Though not commercially feasible, the ore can be directly reduced with potassium, sodium, or calcium in vacuum to produce caesium metal directly.
Most of the mined caesium (as salts) is directly converted into caesium formate (HCOOCs) for applications such as oil drilling. To supply the developing market, Cabot Corporation built a production plant in 1997 at the Tanco mine near Bernic Lake in Manitoba, with a capacity of 12,000 barrels (1,900 m) per year of caesium formate solution. The primary smaller-scale commercial compounds of caesium are caesium chloride and nitrate.
Alternatively, caesium metal may be obtained from the purified compounds derived from the ore. Caesium chloride and the other caesium halides can be reduced at 700 to 800 °C (1,292 to 1,472 °F) with calcium or barium, and caesium metal distilled from the result. In the same way, the aluminate, carbonate, or hydroxide may be reduced by magnesium.
The metal can also be isolated by electrolysis of fused caesium cyanide (CsCN). Exceptionally pure and gas-free caesium can be produced by 390 °C (734 °F) thermal decomposition of caesium azide CsN3, which can be produced from aqueous caesium sulfate and barium azide. In vacuum applications, caesium dichromate can be reacted with zirconium to produce pure caesium metal without other gaseous products.
The price of 99.8% pure caesium (metal basis) in 2009 was about $10 per gram ($280/oz), but the compounds are significantly cheaper.
In 1860, Robert Bunsen and Gustav Kirchhoff discovered caesium in the mineral water from Dürkheim, Germany. Because of the bright blue lines in the emission spectrum, they derived the name from the Latin word caesius, meaning 'bluish grey'. Caesium was the first element to be discovered with a spectroscope, which had been invented by Bunsen and Kirchhoff only a year previously.
To obtain a pure sample of caesium, 44,000 litres (9,700 imp gal; 12,000 US gal) of mineral water had to be evaporated to yield 240 kilograms (530 lb) of concentrated salt solution. The alkaline earth metals were precipitated either as sulfates or oxalates, leaving the alkali metal in the solution. After conversion to the nitrates and extraction with ethanol, a sodium-free mixture was obtained. From this mixture, the lithium was precipitated by ammonium carbonate. Potassium, rubidium, and caesium form insoluble salts with chloroplatinic acid, but these salts show a slight difference in solubility in hot water, and the less-soluble caesium and rubidium hexachloroplatinate ((Cs,Rb)2PtCl6) were obtained by fractional crystallization. After reduction of the hexachloroplatinate with hydrogen, caesium and rubidium were separated by the difference in solubility of their carbonates in alcohol. The process yielded 9.2 grams (0.32 oz) of rubidium chloride and 7.3 grams (0.26 oz) of caesium chloride from the initial 44,000 litres of mineral water.
From the caesium chloride, the two scientists estimated the atomic weight of the new element at 123.35 (compared to the currently accepted one of 132.9). They tried to generate elemental caesium by electrolysis of molten caesium chloride, but instead of a metal, they obtained a blue homogeneous substance which "neither under the naked eye nor under the microscope showed the slightest trace of metallic substance"; as a result, they assigned it as a subchloride (Cs2Cl). In reality, the product was probably a colloidal mixture of the metal and caesium chloride. The electrolysis of the aqueous solution of chloride with a mercury cathode produced a caesium amalgam which readily decomposed under the aqueous conditions. The pure metal was eventually isolated by the Swedish chemist Carl Setterberg while working on his doctorate with Kekulé and Bunsen. In 1882, he produced caesium metal by electrolysing caesium cyanide, avoiding the problems with the chloride.
Historically, the most important use for caesium has been in research and development, primarily in chemical and electrical fields. Very few applications existed for caesium until the 1920s, when it came into use in radio vacuum tubes, where it had two functions; as a getter, it removed excess oxygen after manufacture, and as a coating on the heated cathode, it increased the electrical conductivity. Caesium was not recognized as a high-performance industrial metal until the 1950s. Applications for nonradioactive caesium included photoelectric cells, photomultiplier tubes, optical components of infrared spectrophotometers, catalysts for several organic reactions, crystals for scintillation counters, and in magnetohydrodynamic power generators. Caesium is also used as a source of positive ions in secondary ion mass spectrometry (SIMS).
Since 1967, the International System of Measurements has based the primary unit of time, the second, on the properties of caesium. The International System of Units (SI) defines the second as the duration of 9,192,631,770 cycles at the microwave frequency of the spectral line corresponding to the transition between two hyperfine energy levels of the ground state of caesium-133. The 13th General Conference on Weights and Measures of 1967 defined a second as: "the duration of 9,192,631,770 cycles of microwave light absorbed or emitted by the hyperfine transition of caesium-133 atoms in their ground state undisturbed by external fields".
The largest present-day use of nonradioactive caesium is in caesium formate drilling fluids for the extractive oil industry. Aqueous solutions of caesium formate (HCOOCs)—made by reacting caesium hydroxide with formic acid—were developed in the mid-1990s for use as oil well drilling and completion fluids. The function of a drilling fluid is to lubricate drill bits, to bring rock cuttings to the surface, and to maintain pressure on the formation during drilling of the well. Completion fluids assist the emplacement of control hardware after drilling but prior to production by maintaining the pressure.
The high density of the caesium formate brine (up to 2.3 g/cm, or 19.2 pounds per gallon), coupled with the relatively benign nature of most caesium compounds, reduces the requirement for toxic high-density suspended solids in the drilling fluid—a significant technological, engineering and environmental advantage. Unlike the components of many other heavy liquids, caesium formate is relatively environment-friendly. Caesium formate brine can be blended with potassium and sodium formates to decrease the density of the fluids to that of water (1.0 g/cm, or 8.3 pounds per gallon). Furthermore, it is biodegradable and may be recycled, which is important in view of its high cost (about $4,000 per barrel in 2001). Alkali formates are safe to handle and do not damage the producing formation or downhole metals as corrosive alternative, high-density brines (such as zinc bromide ZnBr2 solutions) sometimes do; they also require less cleanup and reduce disposal costs.
Caesium-based atomic clocks use the electromagnetic transitions in the hyperfine structure of caesium-133 atoms as a reference point. The first accurate caesium clock was built by Louis Essen in 1955 at the National Physical Laboratory in the UK. Caesium clocks have improved over the past half-century and are regarded as "the most accurate realization of a unit that mankind has yet achieved." These clocks measure frequency with an error of 2 to 3 parts in 10, which corresponds to an accuracy of 2 nanoseconds per day, or one second in 1.4 million years. The latest versions are more accurate than 1 part in 10, about 1 second in 20 million years. The caesium standard is the primary standard for standards-compliant time and frequency measurements. Caesium clocks regulate the timing of cell phone networks and the Internet.
The second, symbol s, is the SI unit of time. The BIPM restated its definition at its 26th conference in 2018: "[The second] is defined by taking the fixed numerical value of the caesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to s."
Caesium vapour thermionic generators are low-power devices that convert heat energy to electrical energy. In the two-electrode vacuum tube converter, caesium neutralizes the space charge near the cathode and enhances the current flow.
Caesium is also important for its photoemissive properties, converting light to electron flow. It is used in photoelectric cells because caesium-based cathodes, such as the intermetallic compound K2CsSb, have a low threshold voltage for emission of electrons. The range of photoemissive devices using caesium include optical character recognition devices, photomultiplier tubes, and video camera tubes. Nevertheless, germanium, rubidium, selenium, silicon, tellurium, and several other elements can be substituted for caesium in photosensitive materials.
Caesium iodide (CsI), bromide (CsBr) and fluoride (CsF) crystals are employed for scintillators in scintillation counters widely used in mineral exploration and particle physics research to detect gamma and X-ray radiation. Being a heavy element, caesium provides good stopping power with better detection. Caesium compounds may provide a faster response (CsF) and be less hygroscopic (CsI).
Caesium vapour is used in many common magnetometers.
The element is used as an internal standard in spectrophotometry. Like other alkali metals, caesium has a great affinity for oxygen and is used as a "getter" in vacuum tubes. Other uses of the metal include high-energy lasers, vapour glow lamps, and vapour rectifiers.
The high density of the caesium ion makes solutions of caesium chloride, caesium sulfate, and caesium trifluoroacetate (Cs(O2CCF3)) useful in molecular biology for density gradient ultracentrifugation. This technology is used primarily in the isolation of viral particles, subcellular organelles and fractions, and nucleic acids from biological samples.
Relatively few chemical applications use caesium. Doping with caesium compounds enhances the effectiveness of several metal-ion catalysts for chemical synthesis, such as acrylic acid, anthraquinone, ethylene oxide, methanol, phthalic anhydride, styrene, methyl methacrylate monomers, and various olefins. It is also used in the catalytic conversion of sulfur dioxide into sulfur trioxide in the production of sulfuric acid.
Caesium fluoride enjoys a niche use in organic chemistry as a base and as an anhydrous source of fluoride ion. Caesium salts sometimes replace potassium or sodium salts in organic synthesis, such as cyclization, esterification, and polymerization. Caesium has also been used in thermoluminescent radiation dosimetry (TLD): When exposed to radiation, it acquires crystal defects that, when heated, revert with emission of light proportionate to the received dose. Thus, measuring the light pulse with a photomultiplier tube can allow the accumulated radiation dose to be quantified.
Caesium-137 is a radioisotope commonly used as a gamma-emitter in industrial applications. Its advantages include a half-life of roughly 30 years, its availability from the nuclear fuel cycle, and having Ba as a stable end product. The high water solubility is a disadvantage which makes it incompatible with large pool irradiators for food and medical supplies. It has been used in agriculture, cancer treatment, and the sterilization of food, sewage sludge, and surgical equipment. Radioactive isotopes of caesium in radiation devices were used in the medical field to treat certain types of cancer, but emergence of better alternatives and the use of water-soluble caesium chloride in the sources, which could create wide-ranging contamination, gradually put some of these caesium sources out of use. Caesium-137 has been employed in a variety of industrial measurement gauges, including moisture, density, levelling, and thickness gauges. It has also been used in well logging devices for measuring the electron density of the rock formations, which is analogous to the bulk density of the formations.
Caesium-137 has been used in hydrologic studies analogous to those with tritium. As a daughter product of fission bomb testing from the 1950s through the mid-1980s, caesium-137 was released into the atmosphere, where it was absorbed readily into solution. Known year-to-year variation within that period allows correlation with soil and sediment layers. Caesium-134, and to a lesser extent caesium-135, have also been used in hydrology to measure the caesium output by the nuclear power industry. While they are less prevalent than either caesium-133 or caesium-137, these bellwether isotopes are produced solely from anthropogenic sources.
Caesium and mercury were used as a propellant in early ion engines designed for spacecraft propulsion on very long interplanetary or extraplanetary missions. The fuel was ionized by contact with a charged tungsten electrode. But corrosion by caesium on spacecraft components has pushed development in the direction of inert gas propellants, such as xenon, which are easier to handle in ground-based tests and do less potential damage to the spacecraft. Xenon was used in the experimental spacecraft Deep Space 1 launched in 1998. Nevertheless, field-emission electric propulsion thrusters that accelerate liquid metal ions such as caesium have been built.
Caesium nitrate is used as an oxidizer and pyrotechnic colorant to burn silicon in infrared flares, such as the LUU-19 flare, because it emits much of its light in the near infrared spectrum. Caesium compounds may have been used as fuel additives to reduce the radar signature of exhaust plumes in the Lockheed A-12 CIA reconnaissance aircraft. Caesium and rubidium have been added as a carbonate to glass because they reduce electrical conductivity and improve stability and durability of fibre optics and night vision devices. Caesium fluoride or caesium aluminium fluoride are used in fluxes formulated for brazing aluminium alloys that contain magnesium.
Magnetohydrodynamic (MHD) power-generating systems were researched, but failed to gain widespread acceptance. Caesium metal has also been considered as the working fluid in high-temperature Rankine cycle turboelectric generators.
Caesium salts have been evaluated as antishock reagents following the administration of arsenical drugs. Because of their effect on heart rhythms, however, they are less likely to be used than potassium or rubidium salts. They have also been used to treat epilepsy.
Caesium-133 can be laser cooled and used to probe fundamental and technological problems in quantum physics. It has a particularly convenient Feshbach spectrum to enable studies of ultracold atoms requiring tunable interactions.
Nonradioactive caesium compounds are only mildly toxic, and nonradioactive caesium is not a significant environmental hazard. Because biochemical processes can confuse and substitute caesium with potassium, excess caesium can lead to hypokalemia, arrhythmia, and acute cardiac arrest, but such amounts would not ordinarily be encountered in natural sources.
The median lethal dose (LD50) for caesium chloride in mice is 2.3 g per kilogram, which is comparable to the LD50 values of potassium chloride and sodium chloride. The principal use of nonradioactive caesium is as caesium formate in petroleum drilling fluids because it is much less toxic than alternatives, though it is more costly.
Caesium metal is one of the most reactive elements and is highly explosive in the presence of water. The hydrogen gas produced by the reaction is heated by the thermal energy released at the same time, causing ignition and a violent explosion. This can occur with other alkali metals, but caesium is so potent that this explosive reaction can be triggered even by cold water.
It is highly pyrophoric: the autoignition temperature of caesium is −116 °C (−177 °F), and it ignites explosively in air to form caesium hydroxide and various oxides. Caesium hydroxide is a very strong base, and will rapidly corrode glass.
The isotopes 134 and 137 are present in the biosphere in small amounts from human activities, differing by location. Radiocaesium does not accumulate in the body as readily as other fission products (such as radioiodine and radiostrontium). About 10% of absorbed radiocaesium washes out of the body relatively quickly in sweat and urine. The remaining 90% has a biological half-life between 50 and 150 days. Radiocaesium follows potassium and tends to accumulate in plant tissues, including fruits and vegetables. Plants vary widely in the absorption of caesium, sometimes displaying great resistance to it. It is also well-documented that mushrooms from contaminated forests accumulate radiocaesium (caesium-137) in the fungal sporocarps. Accumulation of caesium-137 in lakes has been a great concern after the Chernobyl disaster. Experiments with dogs showed that a single dose of 3.8 millicuries (140 MBq, 4.1 μg of caesium-137) per kilogram is lethal within three weeks; smaller amounts may cause infertility and cancer. The International Atomic Energy Agency and other sources have warned that radioactive materials, such as caesium-137, could be used in radiological dispersion devices, or "dirty bombs". | [

] | Caesium is a chemical element; it has symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegative element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite. Caesium-137, a fission product, is extracted from waste produced by nuclear reactors. It has the largest atomic radius of all elements whose radii have been measured or calculated, at about 260 picometers. The German chemist Robert Bunsen and physicist Gustav Kirchhoff discovered caesium in 1860 by the newly developed method of flame spectroscopy. The first small-scale applications for caesium were as a "getter" in vacuum tubes and in photoelectric cells. In 1967, acting on Einstein's proof that the speed of light is the most-constant dimension in the universe, the International System of Units used two specific wave counts from an emission spectrum of caesium-133 to co-define the second and the metre. Since then, caesium has been widely used in highly accurate atomic clocks. Since the 1990s, the largest application of the element has been as caesium formate for drilling fluids, but it has a range of applications in the production of electricity, in electronics, and in chemistry. The radioactive isotope caesium-137 has a half-life of about 30 years and is used in medical applications, industrial gauges, and hydrology. Nonradioactive caesium compounds are only mildly toxic, but the pure metal's tendency to react explosively with water means that caesium is considered a hazardous material, and the radioisotopes present a significant health and environmental hazard. | 2001-09-15T20:43:10Z | 2023-12-30T08:45:17Z | [

5,881 | Century | A century is a period of 100 years. Centuries are numbered ordinally in English and many other languages. The word century comes from the Latin centum, meaning one hundred. Century is sometimes abbreviated as c.
A centennial or centenary is a hundredth anniversary, or a celebration of this, typically the remembrance of an event which took place a hundred years earlier.
Although a century can mean any arbitrary period of 100 years, there are two viewpoints on the nature of standard centuries. One is based on strict construction, while the other is based on popular perception.
According to the strict construction, the 1st century AD began with AD 1 and ended with AD 100, the 2nd century spanning the years 101 to 200, with the same pattern continuing onward. In this model, the n-th century starts with the year that ends with "01", and ends with the year that ends with "00"; for example, the 20th century comprises the years 1901 to 2000 in strict usage.
In popular perception and practice, centuries are structured by grouping years based on sharing the 'hundreds' digit(s). In this model, the n-th century starts with the year that ends in "00" and ends with the year ending in "99"; for example, the years 1900 to 1999, in popular culture, constitute the 20th century. (This is similar to the grouping of "0-to-9 decades" which share the 'tens' digit.)
To facilitate calendrical calculations by computer, the astronomical year numbering and ISO 8601 systems both contain a year zero, with the astronomical year 0 corresponding to the year 1 BCE, the astronomical year -1 corresponding to 2 BCE, and so on.
Informally, years may be referred to in groups based on the hundreds part of the year. In this system, the years 1900–1999 are referred to as the nineteen hundreds (1900s). Aside from English usage, this system is used in Swedish, Danish, Norwegian, Icelandic, Finnish and Hungarian. The Swedish nittonhundratalet (or 1900-talet), Danish nittenhundredetallet (or nittenhundredetallet), Norwegian nittenhundretallet (or 1900-tallet), Finnish tuhatyhdeksänsataaluku (or 1900-luku) and Hungarian ezerkilencszázas évek (or 1900-as évek) refer unambiguously to the years 1900–1999.
Italian also has a similar system, but it only expresses the hundreds and omits the word for 'thousand'. This system mainly functions from the 11th to the 20th century:
These terms are often used in other languages when referring to the history of Italy.
While the century has been commonly used in the West, other cultures and calendars have utilized differently sized groups of years in a similar manner. The Hindu calendar, in particular, summarizes its years into groups of 60, while the Aztec calendar considers groups of 52. | [

5,882 | Cardiff | Cardiff (/ˈkɑːrdɪf/; Welsh: Caerdydd [kairˈdiːð, kaːɨrˈdɨːð] ) is the capital and largest city of Wales. Cardiff had a population of 362,310 in 2021 and forms a principal area officially known as the City and County of Cardiff (Welsh: Dinas a Sir Caerdydd). The city is the eleventh largest in the United Kingdom. Located in the southeast of Wales and in the Cardiff Capital Region, Cardiff is the county town of the historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. Cardiff Built-up Area covers a larger area outside the county boundary, including the towns of Dinas Powys and Penarth.
Cardiff is the main commercial centre of Wales as well as the base for the Senedd, the Welsh Parliament. At the 2021 census, the unitary authority area population was put at 362,400. The population of the wider urban area in 2011 was 479,000. In 2011, it ranked sixth in the world in a National Geographic magazine list of alternative tourist destinations. It is the most popular destination in Wales with 21.3 million visitors in 2017.
Cardiff is a major centre for television and film production (such as the 2005 revival of Doctor Who, Torchwood and Sherlock) and is the Welsh base for the main national broadcasters.
Cardiff Bay contains the Senedd building and the Wales Millennium Centre arts complex. Work continues at Cardiff Bay and in the centre on projects such as Cardiff International Sports Village, BBC drama village, and a new business district.
Caerdydd (the Welsh name of the city) derives from the Middle Welsh Caerdyf. The change from -dyf to -dydd shows the colloquial alteration of Welsh f [v] and dd [ð] and was perhaps also driven by folk etymology. This sound change probably first occurred in the Middle Ages; both forms were current in the Tudor period. Caerdyf has its origins in post-Roman Brythonic words meaning "the fort of the Taff". The fort probably refers to that established by the Romans. Caer is Welsh for fort and -dyf is in effect a form of Taf (Taff), the river which flows by Cardiff Castle, with the ⟨t⟩ showing consonant mutation to ⟨d⟩ and the vowel showing affection as a result of a (lost) genitive case ending.
The anglicised Cardiff is derived from Caerdyf, with the Welsh f [v] borrowed as ff /f/, as also happens in Taff (from Welsh Taf) and Llandaff (from Welsh Llandaf).
The antiquarian William Camden (1551–1623) suggested that the name Cardiff may derive from *Caer-Didi ("the Fort of Didius"), a name supposedly given in honour of Aulus Didius Gallus, governor of a nearby province at the time when the Roman fort was established. Although some sources repeat this theory, it has been rejected on linguistic grounds by modern scholars such as Professor Gwynedd Pierce.
Archaeological evidence from sites in and around Cardiff show that people had settled in the area by at least around 6000 BC, during the early Neolithic; about 1,500 years before either Stonehenge or the Great Pyramid of Giza was completed. These include the St Lythans burial chamber near Wenvoe, (approximately four miles or six km west of Cardiff city centre); the Tinkinswood burial chamber, near St. Nicholas (about six miles or ten km west of Cardiff city centre), the Cae'rarfau Chambered Tomb, Creigiau (about six miles or ten km northwest of Cardiff city centre) and the Gwern y Cleppa long barrow, near Coedkernew, Newport (about eight miles or thirteen km northeast of Cardiff city centre). A group of five Bronze Age tumuli is at the summit of the Garth, within the county's northern boundary. Four Iron Age hill fort and enclosure sites have been identified within Cardiff's county boundaries, including Caerau Hillfort, an enclosed area of 5.1 hectares (12+1⁄2 acres).
Until the Roman conquest of Britain, Cardiff was part of the territory of the Silures – a Celtic British tribe that flourished in the Iron Age – whose territory included the areas that would become known as Breconshire, Monmouthshire and Glamorgan. The 3.2 ha (8-acre) fort established by the Romans near the mouth of the River Taff in AD 75, in what would become the north western boundary of the centre of Cardiff, was built over an extensive settlement that had been established by the Romans in the 50s AD. The fort was one of a series of military outposts associated with Isca Augusta (Caerleon) that acted as border defences. The fort may have been abandoned in the early 2nd century as the area had been subdued. However, by this time a civilian settlement, or vicus, was established. It was likely made up of traders who made a living from the fort, ex-soldiers and their families. A Roman villa has been discovered at Ely. Contemporary with the Saxon Shore forts of the 3rd and 4th centuries, a stone fortress was established at Cardiff. Similar to the shore forts, the fortress was built to protect Britannia from raiders. Coins from the reign of Gratian indicate that Cardiff was inhabited until at least the 4th century; the fort was abandoned towards the end of the 4th century, as the last Roman legions left the province of Britannia with Magnus Maximus.
Little is known of the fort and civilian settlement in the period between the Roman departure from Britain and the Norman Conquest. The settlement probably shrank in size and may even have been abandoned. In the absence of Roman rule, Wales was divided into small kingdoms; early on, Meurig ap Tewdrig emerged as the local king in Glywysing (which later became Glamorgan). The area passed through his family until the advent of the Normans in the 11th century.
In 1081 William I, King of England, began work on the castle keep within the walls of the old Roman fort. Cardiff Castle has been at the heart of the city ever since. The castle was substantially altered and extended during the Victorian period by John Crichton-Stuart, 3rd Marquess of Bute, and the architect William Burges. Original Roman work can, however, still be distinguished in the wall facings.
A town grew up under the castle, consisting mainly of settlers from England. Cardiff had a population of between 1,500 and 2,000 in the Middle Ages – a normal size for a Welsh town in the period. It was the centre of the Norman Marcher Lordship of Glamorgan. By the end of the 13th century, Cardiff was the only town in Wales with a population exceeding 2,000, although it remained relatively small compared with notable towns in England and continued to be contained within its walls, which were begun as a wooden palisade in the early 12th century. It was of sufficient size and importance to receive a series of charters, notably in 1331 from William La Zouche, Lord of Glamorgan through marriage with the de Clare family, Edward III in 1359, then Henry IV in 1400, and later Henry VI.
In 1404, Owain Glyndŵr burned Cardiff and took possession of the Castle. As many of the buildings were made of timber and tightly packed within the town walls, much of Cardiff was destroyed. The settlement was soon rebuilt on the same street plan and began to flourish again. (Glyndŵr's statue was erected in Cardiff Town Hall in the early 20th century, reflecting the complex, often conflicting cultural identity of Cardiff as capital of Wales.) Besides serving an important political role in the governance of the fertile south Glamorgan coastal plain, Cardiff was a busy port in the Middle Ages and declared a staple port in 1327.
In 1536, the Laws in Wales Acts 1535–1542 led to the creation of Glamorganshire and Cardiff was made the county town, it also became part of Kibbor hundred, around the same time the Herberts became the most powerful family in the area. In 1538, Henry VIII closed Cardiff's Dominican and Franciscan friaries, whose remains were used as building materials. A writer in this period noted: "The River Taff runs under the walls of his honours castle and from the north part of the town to the south part where there is a fair quay and a safe harbour for shipping."
Cardiff became a borough in 1542 and further Royal Charters were granted to it by Elizabeth I in 1600 and James I in 1608. In 1573, it was made a head port for collection of customs duties. Pembrokeshire historian George Owen described Cardiff in 1602 as "the fayrest towne in Wales yett not the welthiest". It gained a second Royal Charter in 1608.
A disastrous flood in the Bristol Channel on 30 January 1607 (now believed to have been a tidal wave) changed the course of the River Taff and ruined St Mary's Parish Church, which was replaced by a chapel of ease dedicated to St John the Baptist.
During the Second English Civil War St Fagans, just to the west of the town, the Battle of St Fagans, between Royalist rebels and a New Model Army detachment, was a decisive victory for the Parliamentarians that allowed Oliver Cromwell to conquer Wales. It was the last major battle in Wales, with about 200, mostly Royalist soldiers killed.
Cardiff was at peace throughout the ensuing century. In 1766, John Stuart, 1st Marquess of Bute married into the Herbert family and was later created Baron Cardiff. In 1778, he began renovating Cardiff Castle. A racecourse, printing press, bank and coffee house opened in the 1790s and Cardiff gained a stagecoach service to London. Despite these improvements, Cardiff's position in the Welsh urban hierarchy declined over the 18th century. Iolo Morganwg called it "an obscure and inconsiderable place" and the 1801 census found a population of only 1,870, making it only the 25th largest town in Wales, well behind Merthyr and Swansea.
In 1793, John Crichton-Stuart, 2nd Marquess of Bute was born. He spent his life building the Cardiff docks and was later hailed as "the creator of modern Cardiff". A twice-weekly boat service between Cardiff and Bristol opened in 1815, and in 1821, the Cardiff Gas Works was established.
After the Napoleonic Wars Cardiff suffered some social and industrial unrest, starting with the trial and hanging of Dic Penderyn in 1831.
The town grew rapidly from the 1830s onwards, when the Marquess of Bute built a dock, which eventually linked to the Taff Vale Railway. Cardiff became the main port for coal exports from the Cynon, Rhondda, and Rhymney valleys, and grew in population at a rate of nearly 80 per cent per decade between 1840 and 1870. Much of this was due to migration from within and outside Wales: in 1841, a quarter of Cardiff's population were English-born and more than 10 per cent born in Ireland. By the 1881 census, Cardiff had overtaken Merthyr and Swansea to become the largest town in Wales. Cardiff's status as the premier town in South Wales was confirmed when it was chosen as the site for the University College of South Wales and Monmouthshire in 1883.
A permanent military presence was established with the completion of Maindy Barracks in 1877.
Cardiff faced a challenge in the 1880s when David Davies of Llandinam and the Barry Railway Company promoted rival docks at Barry. These had the advantage of being accessible in all tides: David Davies claimed his venture would cause "grass to grow in the streets of Cardiff". From 1901 coal exports from Barry surpassed those from Cardiff, but the administration of the coal trade remained centred on Cardiff, in particular its Coal Exchange, where the price of coal on the British market was determined and the first million-pound deal was struck in 1907. The city also strengthened its industrial base when the owners of the Dowlais Ironworks in Merthyr (who would later form part of Guest, Keen and Nettlefolds) built a steelworks close to the docks at East Moors, which Lord Bute opened on 4 February 1891.
Cardiff became a county borough on 1 April 1889 under the Local Government Act 1888. The town had grown rapidly and had a population of over 123,000. It retained its county borough status until 1974.
King Edward VII granted Cardiff city status on 28 October 1905. It acquired a Roman Catholic cathedral in 1916. Later, more national institutions came to the city, including the National Museum of Wales, the Welsh National War Memorial, and the University of Wales Registry Building, but it was denied the National Library of Wales, partly because the library's founder, Sir John Williams, considered Cardiff to have "a non-Welsh population".
After a brief post-war boom, Cardiff docks entered a prolonged decline in the interwar period. By 1936, trade was at less than half its value in 1913, reflecting the slump in demand for Welsh coal. Bomb damage in the Cardiff Blitz of World War II included the devastation of Llandaff Cathedral, and in the immediate postwar years, the city's link with the Bute family came to an end.
The city was recognised as the capital city of Wales on 20 December 1955, in a written reply by the Home Secretary, Gwilym Lloyd George. Caernarfon had also vied for the title. Welsh local authorities had been divided: only 76 out of 161 chose Cardiff in a 1924 poll organised by the South Wales Daily News. The subject was not debated again until 1950, and meanwhile Cardiff took steps to promote its "Welshness". The stalemate between Cardiff and cities such as Caernarfon and Aberystwyth was not broken until Cardiganshire County Council decided to support Cardiff; and in a new local authority vote, 134 out of 161 voted for Cardiff.
Cardiff therefore celebrated two important anniversaries in 2005. The Encyclopedia of Wales notes that the decision to recognise the city as the capital of Wales "had more to do with the fact that it contained marginal Conservative constituencies than any reasoned view of what functions a Welsh capital should have." Although the city hosted the Commonwealth Games in 1958, Cardiff only became a centre of national administration with the establishment of the Welsh Office in 1964, which later prompted the creation of various other public bodies such as the Arts Council of Wales and the Welsh Development Agency, most of which were based in Cardiff.
The East Moors Steelworks closed in 1978 and Cardiff lost population in the 1980s, consistent with a wider pattern of counter-urbanisation in Britain. However, it recovered to become one of the few cities outside London where population grew in the 1990s. During this period the Cardiff Bay Development Corporation was promoting the redevelopment of south Cardiff; an evaluation of the regeneration of Cardiff Bay published in 2004 concluded that the project had "reinforced the competitive position of Cardiff" and "contributed to a massive improvement in the quality of the built environment, although it had "failed "to attract the major inward investors originally anticipated".
In the 1997 Welsh devolution referendum, Cardiff voters rejected the establishment of the National Assembly for Wales by 55.4% to 44.2% on a 47% turnout, which Denis Balsom partly ascribed to a general preference in Cardiff and some other parts of Wales for a British rather than exclusively Welsh identity. The relative lack of local support for the Assembly and difficulties between the Welsh Office and Cardiff Council in acquiring the originally preferred venue, Cardiff City Hall, encouraged other local authorities to bid to house the Assembly. However, the Assembly was eventually located at Tŷ Hywel in Cardiff Bay in 1999. In 2005, a new debating chamber on an adjacent site, designed by Richard Rogers, was opened.
The Senedd (Welsh Parliament; Welsh: Senedd Cymru) has been based in Cardiff Bay since its formation in 1999 as the "National Assembly for Wales". The Senedd building was opened on 1 March 2006 by The Queen. The Members of the Senedd (MSs), the Senedd Commission and ministerial support staff are based in Cardiff Bay.
Cardiff elects four constituency Members of the Senedd to the Senedd; the constituencies for the Senedd are the same as for the UK Parliament. All of the city's electors have an extra vote for the South Wales Central regional members; this system increases proportionality to the Senedd. The most recent Senedd general election was held on 6 May 2021.
In the Senedd, Cardiff is represented by Jenny Rathbone (Labour) in Cardiff Central, Julie Morgan (Labour) in Cardiff North, Vaughan Gething (Labour) in Cardiff South and Penarth and First Minister of Wales Mark Drakeford (Labour) in Cardiff West.
At Westminster, Cardiff is represented by four Labour MPs: Jo Stevens in Cardiff Central, Anna McMorrin in Cardiff North, Stephen Doughty in Cardiff South and Penarth, and Kevin Brennan in Cardiff West.
The Welsh Government is headquartered in Cardiff's Cathays Park, where most of its civil servants are based, with smaller numbers in other central locations: Cathays, Canton, and Cardiff Bay. There are other Welsh Government offices in other parts of Wales, such as Llandudno and Aberystwyth, and there are international offices.
Between 1889 and 1974 Cardiff was a county borough governed by Cardiff County Borough Council (known as Cardiff City Council after 1905). Between 1974 and 1996, Cardiff was governed by Cardiff City Council, a district council of South Glamorgan. Since local government reorganisation in 1996, Cardiff has been governed by the City and County Council of Cardiff, based at County Hall in Atlantic Wharf, Cardiff Bay. Voters elect 75 councillors every four years.
Between the 2004 and 2012 local elections, no individual political party held a majority on Cardiff County Council. The Liberal Democrats held the largest number of seats and Cllr Rodney Berman was Leader of the council. The Liberal Democrats and Plaid Cymru formed a partnership administration. In the 2012 elections the Labour Party achieved an outright majority, after gaining an additional 33 seats across the city.
Cardiff is divided into communities, several with their own community council and the rest governed directly by Cardiff City Council. Elections are held every five years. The last contested elections would have been held at the same time as the 2017 Cardiff Council election had there been more candidates standing than available seats. Those with community councils are:
The centre of Cardiff is relatively flat and bounded by hills to the east, north and west. Its location influenced its development as the world's largest coal port, notably its proximity and easy access to the coalfields of the South Wales Valleys. The highest point in the local authority area is Garth Hill, 307 m (1,007 ft) above sea level.
Cardiff is built on reclaimed marshland on a bed of Triassic stones. This reclaimed marshland stretches from Chepstow to the Ely Estuary, which is the natural boundary of Cardiff and the Vale of Glamorgan. Triassic landscapes of this part of the world are usually shallow and low-lying, consistent with the flatness of the centre of Cardiff. The classic Triassic marl, sand and conglomerate rocks are used predominantly throughout Cardiff as building materials. Many of these Triassic rocks are purplish, especially the coastal marl found near Penarth. One of the Triassic rocks used in Cardiff is "Radyr Stone", a freestone which as its name suggests is quarried in the Radyr district. Cardiff has also imported some materials for buildings: Devonian sandstones (the Old Red Sandstone) from the Brecon Beacons has been used. Most famously, the buildings of Cathays Park, the civic centre in the centre of the city, are built of Portland stone from Dorset. A widely used building stone in Cardiff is the yellow-grey Liassic limestone rock of the Vale of Glamorgan, including the rare "Sutton Stone", a conglomerate of lias limestone and carboniferous limestone.
Cardiff is bordered to the west by the rural district of the Vale of Glamorgan, also known as the Garden of Cardiff, to the east by the city of Newport; to the north by the South Wales Valleys, and to the south by the Severn Estuary and Bristol Channel. The River Taff winds through the city centre and together with the River Ely flows into the freshwater Cardiff Bay. A third river, the Rhymney, flows through the east of the city directly into the Severn Estuary.
Cardiff lies near the Glamorgan Heritage Coast, stretching westward from Penarth and Barry – commuter towns of Cardiff – with striped yellow-blue Jurassic limestone cliffs. The Glamorgan coast is the only part of the Celtic Sea with exposed Jurassic (blue lias) geology. This stretch of coast with its reefs, sandbanks and serrated cliffs was a ship graveyard; many ships sailing to Cardiff during the industrial era were wrecked on this hostile coastline during west/south-westerly gales. Smuggling, deliberate shipwrecking and attacks on ships were also common.
"Inner Cardiff" consists of the wards of Plasnewydd, Gabalfa, Roath, Cathays, Adamsdown and Splott ward on the north and east of the city centre, and Butetown, Grangetown, Riverside and Canton to the south and west. The inner-city areas to the south of the A4161 road, known as the "Southern Arc", are with the exception of Cardiff Bay some of the poorest districts of Wales, with low levels of economic activity. On the other hand, Gabalfa, Plasnewydd and Cathays north of the 'arc' have large student populations, and Pontcanna (north of Riverside and alongside Canton) is a favourite for students and young professionals. Penylan, to the north east of Roath Park, is an affluent area popular with older parents and the retired.
To the west lie Ely and Caerau, which have some of the largest housing estates in the United Kingdom. With the exception of some outlying privately built estates at Michaelston-super-Ely, this is an economically disadvantaged area with high numbers of unemployed households. Culverhouse Cross is a more affluent western area of the city. Fairwater, Heath, Birchgrove, Gabalfa, Mynachdy, Llandaff North, Llandaff, Llanishen, Radyr, Whitchurch & Tongwynlais, Rhiwbina, Thornhill, Lisvane and Cyncoed lie in an arc from the north-west to the north-east of the centre. Lisvane, Cyncoed, Radyr and Rhiwbina contain some of the most expensive housing in Wales.
Further east lie the wards of Pontprennau and Old St Mellons, Rumney, Pentwyn, Llanrumney, Llanedeyrn and Trowbridge. The last four are largely public housing stock, although much new private housing is being built in Trowbridge. Pontprennau is the newest "suburb" of Cardiff, while Old St Mellons has a history going back to the 11th-century Norman Conquest. The region that may be called "Rural Cardiff" contains the villages of St Fagans, Creigiau, Pentyrch, Tongwynlais and Gwaelod-y-garth. In 2017, plans were approved for a new suburb of 7,000 homes between Radyr and St Fagans, known as Plasdŵr. St Fagans, home to the Museum of Welsh Life, is protected from further development.
Since 2000, there has been a marked change of scale and building height in Cardiff, with the development of the city centre's first purpose-built high-rise apartments. Tall buildings have been built in the city centre and Cardiff Bay, and more are planned.
Cardiff, in the north temperate zone, has a maritime climate (Köppen: Cfb) marked by mild weather that is often cloudy, wet and windy. Summers tend to be warm and sunny, with average maxima between 19 and 22 °C (66 and 72 °F). Winters are fairly wet, but excessive rainfall as well as frost are rare. Spring and autumn feel similar and the temperatures tend to stay above 14 °C (57 °F) – also the average annual daytime temperature. Rain is unpredictable at any time of year, although showers tend to be shorter in summer.
The northern part of the county, being higher and inland, tends to be cooler and wetter than the city centre.
Cardiff's maximum and minimum monthly temperatures average 21.5 °C (70.7 °F) (July) and 2.1 °C (35.8 °F) (February).For Wales, the temperatures average 19.1 °C (66.4 °F) (July) and 1.1 °C (34.0 °F) (February).
Cardiff has 1,518 hours of sunshine in an average year (Wales 1,388.7 hours). Cardiff is sunniest in July, with an average 203.4 hours during the month (Wales 183.3 hours), and least sunny in December with 44.6 hours (Wales 38.5 hours).
Cardiff experiences less rainfall than average for Wales. It falls on 146 days in an average year, with total annual rainfall of 1,151.9 mm (45.35 in). Monthly rainfall patterns show that from October to January, average monthly rainfall in Cardiff exceeds 100 mm (3.9 in) each month, the wettest month being December with 125.3 mm (4.93 in) and the driest from April to June, with average monthly rainfall fairly consistent between 65 and 75 mm (2.6 and 3.0 in).
After a period of decline in the 1970s and 1980s, Cardiff's population is growing again. It reached 362,400 in the 2021 census, compared to a 2011 census figure of 346,100. Between mid-2007 and mid-2008, Cardiff was the fastest-growing local authority in Wales, with growth of 1.2%. According to 2001 census data, Cardiff was the 21st largest urban area. The Cardiff Larger Urban Zone (a Eurostat definition including the Vale of Glamorgan and a number of local authorities in the Valleys) has 841,600 people, the 10th largest LUZ in the UK. The Cardiff and South Wales Valleys metropolitan area has a population of nearly 1.1 million.
Official census estimates of the city's total population have been disputed. The city council published two articles arguing that the 2001 census seriously under-reported the population of Cardiff, and in particular the ethnic minority population of some inner city areas.
The Welsh Government's official mid-year estimate of the population of the Cardiff local authority area in 2019 was 366,903. At the 2011, census the official population of the Cardiff Built Up Area (BUA) was put at 447,287. The BUA is not contiguous with the local authority boundary and aggregates data at a lower level; for Cardiff this includes the urban part of Cardiff, Penarth/Dinas Powys, Caerphilly and Pontypridd.
Cardiff has an ethnically diverse population due to past trading connections, post-war immigration and large numbers of foreign students who attend university in the city. The ethnic make-up of Cardiff's population at the 2011 census was: 84.7% White, 1.6% mixed White and Black African/Caribbean, 0.7% mixed White and Asian, 0.6% mixed other, 8.1% Asian, 2.4% Black, 1.4% Arab and 0.6% other ethnic groups. This means almost 53,000 people from a non-white ethnic group reside in the city. This diversity, especially that of the city's long-established African and Arab communities, has been recorded in cultural exhibitions and events, along with books published on this subject.
There are seven NHS hospitals in the city, the largest being the University Hospital of Wales, which is the third largest hospital in the UK and deals with most accidents and emergencies. The University Dental Hospital, which provides emergency treatment, is also located on this site. Llandough Hospital is located in the south of the city.
St. David's Hospital, the city's newest hospital, built behind the former building, is located in Canton and provides services for the elderly and children. Cardiff Royal Infirmary is on Newport Road, near the city centre. The majority of this hospital was closed in 1999, but the west wing remained open for clinic services, genitourinary medicine and rehabilitation treatment. Rookwood Hospital and the Velindre Cancer Centre are also located within Cardiff. They are administered by the Cardiff and Vale University Health Board, with the exception of Velindre, which is run by a separate trust. Spire Healthcare, a private hospital, is in Pontprennau.
Cardiff has a chequered linguistic history with Welsh, English, Latin, Norse and Norman French preponderant at different times. Welsh was the majority language in Cardiff from the 13th century until the city's explosive growth in the Victorian era. As late as 1850, five of the 12 Anglican churches within the current city boundaries conducted their services exclusively in Welsh, while only two worshipped exclusively in English. By 1891, the percentage of Welsh speakers had fallen to 27.9% and only Lisvane, Llanedeyrn and Creigiau remained as majority Welsh-speaking communities. The Welsh language became grouped around a small cluster of chapels and churches, the most notable of which is Tabernacl in the city centre, one of four UK churches chosen to hold official services to commemorate the new millennium.
The city's first Welsh-language school (Ysgol Gymraeg Bryntaf) was established in the 1950s. Welsh has since regained ground. Aided by Welsh-medium education and migration from other parts of Wales, there are now many more Welsh speakers: their numbers doubled between the 1991 and 2011 censuses, from 18,071 (6.6%) to 36,735 (11.1%) residents aged three years and above. The LSOA (Lower Layer Super Output Area) with the highest percentage of Welsh speakers in the city centre is found in Canton, at 25.5%. The LSOA with the highest percentage of Welsh speakers in the whole of Cardiff is Whitchurch, at 26%.
Cardiff City Council adopted a five-year Welsh-language strategy in 2017, aimed at increasing the number of Welsh speakers (aged 3+) in Cardiff by 15.9%, from 36,735 in 2011 to 42,584 residents by the 2021 Census. The ONS estimated that in December 2020, 89,900 (24.8%) of Cardiff's population could speak Welsh.
In addition to English and Welsh, the diversity of Cardiff's population (including foreign students) means that many other languages are spoken. One study has found that Cardiff has speakers of at least 94 languages, with Somali, Urdu, Bengali and Arabic being the most commonly spoken foreign ones.
The modern Cardiff accent is distinct from that of nearby South Wales Valleys. It is marked primarily by:
Due to its diversity and large student population, more people now come to the city to learn English. Foreign students from Arab states and other European countries are a common sight on the streets of Cardiff. The British Council has an office in the city centre and there are six accredited schools in the area.
Since 1922, Cardiff has included Llandaff within its boundary, along with the Anglican Llandaff Cathedral, the parish church of Llandaff and the seat of the Bishop of Llandaff, head of the Church in Wales and the Diocese of Llandaff.
There is a Roman Catholic cathedral in the city. Since 1916, Cardiff has been the seat of a Catholic archbishop, but there appears to have been a fall in the estimated Catholic population, with numbers in 2006 around 25,000 fewer than in 1980. Likewise, the Jewish population appears to have fallen – there are two synagogues in Cardiff, one in Cyncoed and one in Moira Terrace, as opposed to seven at the turn of the 20th century. There are several nonconformist chapels, an early 20th century Greek Orthodox church and 11 mosques. In the 2001 census, 66.9% of Cardiff's population described itself as Christian, a percentage point below the Welsh and UK averages.
The oldest of the non-Christian communities in Wales is Judaism. Jews were not permitted to live in England and Wales between the 1290 Edict of Expulsion and the 17th century. A Welsh Jewish community was re-established in the 18th century. There was once a fairly substantial Jewish population in South Wales, most of which has disappeared. The Orthodox Jewish community congregations are consolidated in the Cardiff United Synagogue in Cyncoed, which was dedicated by Chief Rabbi Jonathan Sacks in 2003. The Cardiff Reform Synagogue is in Adamsdown.
Cardiff's Muslim population is much above the Welsh average and the longest established in the UK, being started by Yemeni and Somali sailors settling in the 19th century. Cardiff now has over 11,000 Muslims with various national affiliations – nearly 52 per cent of the Muslim population in Wales.
The proportion of Cardiff residents declaring themselves Hindu, Sikh and Jewish were all considerably higher than the Welsh averages, but lower than the UK figures. The city has had a Hindu community since Indian immigrants settled in the 1950s and 1960s. The first Hindu temple in the city was opened in Grangetown on 6 April 1979 on the site of an abandoned synagogue. The 25th anniversary of the founding was celebrated in September 2007 with a parade of over 3,000 people through the city centre, including Hindus from across the United Kingdom and members of Cardiff's other religious communities. There are over 2,000 Hindus in Cardiff, worshiping at three temples.
In the 2001 census 18.8% of the city's population stated they had no religion, while 8.6% did not state a religion.
As the capital city of Wales, Cardiff is the main engine of growth in the Welsh economy. Though the population of Cardiff is about 10% of the Welsh population, the economy of Cardiff makes up nearly 20% of Welsh GDP and 40% of the city's workforce are daily in-commuters from the surrounding South Wales area.
Industry has played a major part in Cardiff's development for many centuries. The main catalyst for its transformation from a small town into a big city was the demand for coal required in making iron and later steel, brought to sea by packhorse from Merthyr Tydfil. This was first achieved by building a 25-mile (40 km) canal from Merthyr (510 ft or 160 m above sea level) to the Taff Estuary at Cardiff. Eventually the Taff Vale Railway replaced the canal barges and massive marshalling yards sprang up as new docks were developed in Cardiff – all prompted by the soaring worldwide demand for coal from the South Wales valleys.
At its peak, Cardiff's port area, known as Tiger Bay, became the busiest port in the world and – for some time – the world's most important coal port. In the years leading up to the First World War, more than 10 million tonnes of coal was exported annually from Cardiff Docks. In 1907, Cardiff's Coal Exchange was the first host to a business deal for a million pounds Sterling. The high demand for Welsh coal and specifically Welsh artificial fuel, named Patent Fuel, is shown by the numerous factories producing this fuel, with the same recipe, in the region of Cardiff. Most well known factories were the Star Patent fuel Co., the Crown Patent fuel, the Cardiff Patent fuel etc. After a period of decline, due to low demand on coal, Cardiff's port has started to grow again – over 3 million tonnes of cargo passed through the docks in 2007.
Cardiff today is the main finance and business services centre in Wales, with strong representation of finance and business services in the local economy. This sector, combined with the public administration, education and health sectors, have accounted for about 75% of Cardiff's economic growth since 1991. The city was recently placed seventh overall in the top 50 European cities in the fDI 2008 Cities of the Future list published by the fDi magazine, and ranked seventh in terms of attracting foreign investment. Notable companies such as Legal & General, Admiral Insurance, HBOS, Zurich, ING Direct, The AA, Principality Building Society, 118118, British Gas, Brains, SWALEC Energy and BT, all operate large national or regional headquarters and contact centres in the city, some of them based in Cardiff's office towers such as Capital Tower and Brunel House. Other major employers include NHS Wales and the Senedd. On 1 March 2004, Cardiff was granted Fairtrade City status.
Cardiff is one of the most popular tourist destinations in the United Kingdom, receiving 18.3 million visitors in 2010 and generating £852 million for the city's economy. One result is that one in five employees in Cardiff is based in the distribution, hotels and restaurants sector, highlighting the growing retail and tourism industries in the city. The city has many hotels of varying sizes and standards, providing almost 9,000 available beds.
Cardiff is home to the Welsh media and a large media sector with BBC Cymru Wales, S4C and ITV Wales all having studios in the city. There is a large independent TV production industry sector of over 600 companies, employing around 6,000, with a turnover estimated at £350 million. Just to the north-west of the city, in Rhondda Cynon Taff, the first completely new film studios in the UK for 30 years are being built, to be named Valleywood. The studios are set to be the biggest in the UK. In 2011 the BBC completed the Roath Lock studios in Cardiff Bay to film dramas such as Casualty, Doctor Who, and Pobol y Cwm.
Cardiff has several regeneration projects, such as St David's 2 Centre and surrounding areas of the city centre, and the £1.4 billion International Sports Village in Cardiff Bay, which played a part in the London 2012 Olympics. It features the only Olympic-standard swimming pool in Wales, the Cardiff International Pool, which opened on 12 January 2008.
According to the Welsh Rugby Union, the Principality Stadium contributed £1 billion to the Welsh economy in the ten years after it opened in 1999, with around 85% of that staying in the Cardiff area.
Most of Cardiff's shopping portfolio is in the city centre around Queen Street, St Mary Street and High Street, with large suburban retail parks in Cardiff Bay, Culverhouse Cross, Leckwith, Newport Road and Pontprennau, together with markets in the city centre and Splott. A £675 million regeneration programme for Cardiff's St. David's Centre was completed in 2009, providing a total of 1,400,000 sq ft (130,000 m) of shopping space, making it one of the largest shopping centres in the United Kingdom. The centre was named the international shopping centre of the year in 2010 by Retail Leisure International (RLI).
The Castle Quarter is a commercial area in the north of the city centre, which includes some of Cardiff's Victorian and Edwardian arcades: Castle Arcade, Morgan Arcade and Royal Arcade, and principal shopping streets: St Mary Street, High Street, The Hayes, and Queen Street.
Cardiff Central railway station is the largest railway station in Wales, with nine platforms coping with over 12.5 million passengers a year. It provides direct services to Bridgend and Newport, long-distance, cross-Wales services to Wrexham and Holyhead, and services to Bristol, Birmingham, Manchester and London. Cardiff Central Station is situated within the southern border of what was known Temperance Town, a former residential area within central Cardiff.
Cardiff Queen Street railway station is the second busiest in Wales and the hub for the Valley Lines services that connect the South Wales Valleys and the Cardiff suburbs with the city centre. It is located at the eastern end of the city centre and provides services to Cardiff Bay. Cardiff has a suburban rail system known as the Valleys & Cardiff Local Routes, operated by Transport for Wales. There are eight lines that serve 20 stations in the city, 26 in the wider urban area (including Taffs Well, Penarth and Dinas Powys) and more than 60 in the South Wales valleys and the Vale of Glamorgan.
The South Wales Metro is an integrated public transport system under development in south-east Wales, centered on Cardiff. The project is to include the electrification of some of the existing railway lines and the creation of multiple light rail and light rapid transit lines. Four lines are under construction with a further three planned. The first lines will link Penarth and Cardiff Bay to Radyr, Treherbert, Aberdare and Merthyr Tydfil, with plans to also serve Pontyclun, St Mellons and Porth Teigr. Alongside this, current commuter services will be improved with a near-tripling in capacity on some routes to Bridgend and Rhymney.
Domestic and international air links to Cardiff and South & West Wales are provided from Cardiff Airport (CWL), the only international airport in Wales. The airport lies in the village of Rhoose, 10 miles (16 km) west of the city. There are regular bus services linking the airport with Cardiff city centre, and a train service from Rhoose Cardiff International Airport railway station to Cardiff Central.
The M4 motorway connects Cardiff with Swansea to the west and Newport and London to the east, with four junctions on the M4, including one with the A48(M). The A470 provides an important link from the city to the Heads of the Valleys road. When completed, the A4232 – also known as the Peripheral Distributor Road – will form part of the Cardiff ring-road system, along with the M4 motorway between junctions 30 and 33.
Cardiff has a comprehensive bus network, whose providers include the municipal bus company Cardiff Bus (routes within the city and to Newport, Barry and Penarth), Adventure Travel (cross-city and to Cardiff Airport), Stagecoach South Wales (to the South Wales Valleys) and First Cymru (to Cowbridge and Bridgend). National Express and Megabus provides direct services to major cities such as Bristol, London, Newcastle upon Tyne and Manchester.
The Taff Trail is a walking and cycle path running for 55 miles (90 km) between Cardiff Bay and Brecon in the Brecon Beacons National Park. It runs through Bute Park, Sophia Gardens and many other green areas within Cardiff. It is possible to cycle the entire distance of the Trail almost completely off-road, as it largely follows the River Taff and many of the disused railways of the Glamorganshire valleys.
Nextbike have operated a public bike-hire scheme in the city since March 2018.
The Aquabus water taxi runs every hour between the city centre (Taff Mead Embankment) and Cardiff Bay (Mermaid Quay), and between Cardiff Bay and Penarth Cardiff Bay Barrage. Throughout the year, Cardiff Waterbus sail between the Pierhead on The Waterfront and the Penarth end of the Cardiff Bay Barrage with short sightseeing cruises.
Between March and October boats depart from Cardiff Bay for Flat Holm Island. The PS Waverley and MV Balmoral sail from Britannia Quay (in Roath Basin) to various destinations in the Bristol Channel.
029 is the current telephone dialling code for Cardiff,as well as for the neighbouring towns of Penarth, Dinas Powys and Caerphilly. The dialling code is optional when dialling within the area: one can dial between any two phones within the 029 code using only the eight-digit local number.
Prior to the Big Number Change on 22 April 2000 the area had shorter, six-digit local numbers with an area code of 01222. This was 0222 before May 1995, derived from 0 (indicating it was a trunk call), 22 (CA on a telephone pad, for CArdiff) and 2 (as 220 was used for CAmbridge and 221 for BAth). Before the introduction of automated trunk call dialling, non-local numbers were accessed through a system of manual telephone exchanges, in common with rest if the United Kingdom.
There remains a common misconception that local numbers are still six digits long and that the code is 02920, even though there are newer Cardiff numbers in the ranges (029) 21xx xxxx and (029) 22xx xxxx.
Cardiff is home to four major institutions of higher education: Cardiff University, Cardiff Metropolitan University, University of South Wales and the Royal Welsh College of Music & Drama.
Cardiff University was founded by a royal charter in 1883 as the University College of South Wales and Monmouthshire, is a member of the Russell Group of leading research led universities, having most of its campus in Cathays and the city centre. Cardiff Metropolitan University (formerly UWIC) has campuses in the Llandaff, Cyncoed and city centre areas, and is part of the confederal University of Wales. The Royal Welsh College of Music & Drama is a conservatoire established in 1949 and is based in the grounds of Cardiff Castle. The University of South Wales's Cardiff campus, Atrium, is home to the Cardiff School of Creative & Cultural Industries and is located in the city centre.
The total number of higher education students in the city is around 43,900. The city also has two further education colleges: Cardiff and Vale College and St David's College. The former is the result of a merger, completed in August 2011, between Coleg Glan Hafren and Barry College. Further education is also offered at most high schools in the city.
Cardiff has three state nursery schools (one bilingual), 98 state primary schools (two bilingual, fifteen Welsh medium), and 19 state secondary schools (three Welsh medium). There are also several independent schools in the city, including St John's College, Llandaff Cathedral School, Cardiff Sixth Form College, Kings Monkton School and Howell's School, a single-sex girls' school (until sixth form). In 2013 Cardiff Sixth Form College came top of the independent senior schools in the UK, which were based on the percentage of A* and A at Advanced Level. Also in the top 100 were St John's College and Howell's School.
Notable schools include Whitchurch High School (the largest secondary school in Wales), Fitzalan High School (one of the most multi-cultural state schools in the UK), and Ysgol Gyfun Gymraeg Glantaf (the largest Welsh medium secondary school in Wales).
As well as academic institutions, Cardiff is also home to other educational and learning organisations such as Techniquest, a hands-on science discovery centre that now has franchises throughout Wales, and is part of the Wales Gene Park in collaboration with Cardiff University, NHS Wales and the Welsh Development Agency (WDA). Cardiff is also home of the largest regional office of the International Baccalaureate Organisation (IBO). This office is home to the organisation's curriculum and assessment centre, which is responsible for overseeing the creation and grading of various IBDP assessments.
Cardiff has many landmark buildings such as the Principality Stadium, Pierhead Building, the Welsh National Museum and the Senedd building, the home of the Welsh Parliament. Cardiff is also famous for Cardiff Castle, St David's Hall, Llandaff Cathedral and the Wales Millennium Centre.
Cardiff Castle is a major tourist attraction in the city and is situated in the heart of the city centre. The National History Museum at St Fagans in Cardiff is a large open-air museum housing dozens of buildings from throughout Welsh history that have been moved to the site in Cardiff. The Civic Centre in Cathays Park comprises a collection of Edwardian buildings such as the City Hall, National Museum and Gallery of Wales, Cardiff Crown Court, and buildings forming part of Cardiff University, together with more modern civic buildings. These buildings are laid out around the Queen Alexandra Gardens, a formal park which contains the Welsh National War Memorial and a number of other, smaller memorials.
In addition to Cardiff Castle, Castell Coch is a castle in Tongwynlais, in the north of the city. The current castle is an elaborately decorated Victorian folly designed by William Burges for the Marquess and built in the 1870s, as an occasional retreat. However, the Victorian castle stands on the footings of a much older medieval castle possibly built by Ifor Bach, a regional baron with links to Cardiff Castle also. The exterior has become a popular location for film and television productions. It rarely fulfilled its intended role as a retreat for the Butes, who seldom stayed there. For the Marquess, the pleasure had been in its creation, a pleasure lost following Burges's death in 1881.
Cardiff claims the largest concentration of castles of any city in the world. As well as Cardiff Castle and Castell Coch, there are the remains of two motte-and-bailey castles in Morganstown and Rhiwbina, known as Morganstown Castle Mound and Twmpath Castle or Twmpath Motte (also known as Welsh: Caer Cynwrig) respectively. Twmpath being a Welsh word for a small mound), which along with a castle at Whitchurch (known as Treoda and destroyed by housing in the 1960s) formed an arc of fortifications which divided the Norman lordship from the Welsh lordship of Senghenydd. Further up the Cefn Cibwr ridge on the boundary with Caerphilly there is also another ruined castle, known as Morgraig Castle (Welsh: Castell Morgraig). Archaeological evidence suggests this castle was never finished, and it is debated whether the fortification was of Norman or Welsh origin. The concentration of castles indicates the moveable nature of the border between the Norman lordship of Glamorgan, centred at Cardiff, and its Welsh neighbours to the north.
There is also the ruined Llandaff Bishop's Palace, also known as Llandaff Castle, which was the home of the medieval bishops, which was destroyed about 1403–1404 by the Welsh leader Owain Glyndŵr. Now only the ruined gatehouse remains. Not strictly a castle in the historical sense, Saint Fagans Castle is a preserved 17th-century manor house, once the seat of the Earls of Plymouth.
Other major tourist attractions are the Cardiff Bay regeneration sites, which include the recently opened Wales Millennium Centre and the Senedd building, and many other cultural and sites of interest, including the Cardiff Bay Barrage and the famous Coal Exchange. The New Theatre was founded in 1906 and refurbished in the 1980s. Until the opening of the Wales Millennium Centre in 2004, it was the premier venue in Wales for touring theatre and dance companies. Other venues popular for concerts and sporting events include Cardiff International Arena, St David's Hall and the Principality Stadium. Cardiff Story, a museum documenting the city's history, has been open to the public since the spring of 2011.
Cardiff has over 1,000 listed buildings, ranging from the more prominent buildings such as the castles, to smaller buildings, houses and structures. Cathedral Road was developed by the 3rd Marquis of Bute and is lined by fine villas, some backing on to Sophia Gardens.
Cardiff has walks of special interest for tourists and ramblers alike, such as the Centenary Walk, which runs for 2+1⁄4 miles (3.5 km) within Cardiff city centre. This route passes through many of Cardiff's landmarks and historic buildings. The Animal Wall, designed by William Burges in 1866, marks the south edge of Bute Park on Castle Street. It bears 15 carved animal statues.
Cardiff has many cultural sites varying from the historical Cardiff Castle and out of town Castell Coch to the more modern Wales Millennium Centre and Cardiff Bay. Cardiff was a finalist in the European Capital of Culture 2008. In recent years Cardiff has grown in stature as a tourist destination, with recent accolades including Cardiff being voted the eighth favourite UK city by readers of the Guardian.
The city was also listed as one of the top 10 destinations in the UK on the official British tourist boards website Visit Britain, and US travel guide Frommers have listed Cardiff as one of 13 top destinations worldwide for 2008. Annual events in Cardiff that have become regular appearances in Cardiff's calendar include Sparks in the Park, The Great British Cheese Festival, Pride Cymru (formerly Cardiff Mardi Gras), Cardiff Winter Wonderland, Cardiff Festival and Made in Roath.
A large number of concerts are held in the city, the larger ones at St David's Hall, Cardiff International Arena and occasionally the Principality Stadium. A number of festivals are also held in Cardiff, the largest being the Cardiff Big Weekend Festival, held annually in the city centre in the summer and playing host to free musical performances (from artists such as Ash, Jimmy Cliff, Cerys Matthews, the Fun Loving Criminals, Soul II Soul and the Magic Numbers), fairground rides and cultural events such as a Children's Festival that takes place in the grounds of Cardiff Castle. The annual festival claims to be the UK's largest free outdoor festival, attracting over 250,000 visitors in 2007.
Cardiff hosted the National Eisteddfod in 1883, 1899, 1938, 1960, 1978, 2008 and 2018. Cardiff is unique in Wales in having two permanent stone circles used by the Gorsedd of Bards during Eisteddfodau. The original circle stands in Gorsedd Gardens in front of the National Museum while its 1978 replacement is situated in Bute Park. Since 1983, Cardiff has hosted the BBC Cardiff Singer of the World competition, a world-renowned event on the opera calendar which is held every two years. The city also hosts smaller events.
The Wales Millennium Centre hosts performances of opera, ballet, dance, comedy, musicals and is home to the BBC National Orchestra of Wales. St David's Hall (which hosts the Singer of the World competition) has regular performances of classical music and ballet as well as music of other genres. The largest of Cardiff's theatres is the New Theatre, situated in the city centre just off Queen Street. Other such venues include the Sherman Theatre, Chapter Arts Centre and the Gate Arts Centre.
The Cardiff music scene is established and wide-ranging: home to the BBC National Orchestra of Wales and the Welsh National Opera; has produced several leading acts; has acted as a springboard for Welsh bands to become famous. Acts hailing from Cardiff include Charlotte Church, Shirley Bassey, Iwan Rheon, the Oppressed, Kids In Glass Houses, Los Campesinos, the Hot Puppies, the School, We're No Heroes, Budgie and Shakin' Stevens. Also, performers such as the Automatic, Manic Street Preachers, Lostprophets, Underworld, Super Furry Animals, Catatonia and Bullet for My Valentine have links with the city and are associated with the Cardiff music scene. In 2010, Cardiff was named the UK's second "most musical" city by PRS for Music.
Cardiff has held a photomarathon in the city each year since 2004, in which photographers compete to take the best 12 pictures of 12 previously unknown topics in 12 hours. An exhibition of winners and other entries is held in June/July each year.

The Principality Stadium hosted 11 football matches during the 2012 Summer Olympics, including the opening event and the men's bronze medal match.
Cardiff has strong nightlife. Most clubs and bars are situated in the city centre, especially St Mary Street. More recently Cardiff Bay has built up a strong night scene, with many modern bars and restaurants. The Brewery Quarter on St Mary Street is a recently developed venue for bars and restaurant with a central courtyard. Charles Street is also a popular part of the city.
Cardiff is known for its extensive parks and other green spaces covering around 10% of the city's total area. Cardiff's main park, Bute Park (which was formerly the castle grounds) extends northwards from the top of one of Cardiff's main shopping street (Queen Street); when combined with the adjacent Llandaff Fields and Pontcanna Fields to the north-west it produces a massive open space skirting the River Taff. Other popular parks include Roath Park in the north, donated to the city by the 3rd Marquess of Bute in 1887, which includes a popular boating lake; Victoria Park, Cardiff's first official park; and Thompson's Park, formerly home to an aviary removed in the 1970s. Wild open spaces include Howardian Local Nature Reserve, 32 acres (13 ha) of the lower Rhymney valley in Penylan noted for its orchids, and Forest Farm Country Park, over 150 acres (61 ha) along the River Taff in Whitchurch.
Cardiff is one of the top ten retail destinations in the UK with Queen Street and St. Mary Street as the two main shopping streets with the three shopping arcades, St. David's Centre, Queens Arcade and the Capitol Centre. The current expansion of St. David's Centre as part of the St David's 2 project has made it one of the largest shopping centres in the UK. As well as the modern shopping arcades, the city is home to Victorian shopping centres, such as High Street Arcade, Castle Arcade, Wyndham Arcade, Royal Arcade and Morgan Arcade. Also of note is The Hayes, home to Spillers Records, the world's oldest record shop.

Cardiff City have played in the English Football League since the 1920–21 season, climbing to Division 1 after one season. Cardiff City are the only non-English team to have won the FA Cup, beating Arsenal in the 1927 final at Wembley Stadium. They were runners up to Portsmouth in the 2008 final, losing 1–0 at the new Wembley Stadium. In the 2013/14 and 2018/19 seasons Cardiff City played in the English Premier League.
Cardiff Metropolitan University F.C. of the Athletic Union of Cardiff Metropolitan University, based in Cyncoed, play in the Cymru Premier, having been promoted from Welsh League Division One in 2016. They were winners of the Welsh League Cup for the 2018–19 season.
Cardiff has numerous smaller clubs including Bridgend Street A.F.C., Caerau (Ely) A.F.C., Cardiff Corinthians F.C., Cardiff Grange Harlequins A.F.C., and Ely Rangers A.F.C., which all play in the Welsh football league system.
In addition to men's football teams Cardiff City Ladies of the FA Women's Premier League Southern Division are based in the city. Teams in the Welsh Premier Women's Football League are Cardiff Met. Ladies, Cyncoed Ladies and Cardiff City.
During the 1990s, London-based football club Wimbledon FC expressed interest in relocating to Cardiff, having been without a home of their own since exiting Plough Lane stadium in 1991 and sharing with Crystal Palace FC at Selhurst Park. The relocation of the club to Cardiff did not happen; in 2003, the club moved to Milton Keynes and a year later rebranded as Milton Keynes Dons.
Cardiff Arms Park (Welsh: Parc yr Arfau Caerdydd), in central Cardiff, is among the world's most famous venues—being the scene of three Welsh Grand Slams in the 1970s (1971, 1976 and 1978) and six Five Nations titles in nine years—and was the venue for Wales' games in the 1991 Rugby World Cup. The Arms Park has a sporting history dating back to at least the 1850s, when Cardiff Cricket Club (formed 1819) relocated to the site. The ground was donated to Cardiff CC in 1867 by the Marquess of Bute. Cardiff Cricket Club shared the ground with Cardiff Rugby Football Club (founded 1876) — forming Cardiff Athletic Club between them — until 1966, when the cricket section moved to Sophia Gardens. Cardiff Athletic Club and the Welsh Rugby Union established two stadia on the site—Cardiff RFC played at their stadium at the northern end of the site, and the Wales national rugby union team played international matches at the National Stadium, Cardiff Arms Park, which opened in 1970. The National Stadium was replaced by the 74,500 capacity Millennium Stadium (Welsh: Stadiwm y Mileniwm) in 1999—in time for the 1999 Rugby World Cup—and is home stadium to the Wales national rugby and football teams for international matches. In addition to Wales' Six Nations Championship and other international games, the Principality Stadium held four matches in the 2007 Rugby World Cup and six FA Cup finals (from the 2001–02 to 2005–06 seasons) while Wembley Stadium was being rebuilt.
Cardiff Cricket Club was formed in 1819 and Glamorgan County Cricket Club has competed as a first-class county since 1921. Its headquarters and ground is the SWALEC Stadium, Sophia Gardens, since moving from Cardiff Arms Park in 1966. The Sophia Gardens stadium underwent multimillion-pound improvements since being selected to host the first "England" v Australia Test match of the 2009 Ashes series. The Hundred franchise team Welsh Fire is also based at the stadium.
Cardiff has a long association with boxing, from 'Peerless' Jim Driscoll — born in Cardiff in 1880 — to more recent, high-profile fights staged in the city. These include the WBC Lennox Lewis vs. Frank Bruno heavyweight championship fight at the Arms Park in 1993, and many of Joe Calzaghe's fights, between 2003 and 2007.
Cardiff's professional ice hockey team, the Cardiff Devils, plays in the 3,000-seat Ice Arena Wales in the Cardiff International Sports Village. It plays in the 12-team professional Elite Ice Hockey League. Founded in 1986, it was one of the most successful British teams in the 1990s.
Cardiff's only American-flag football team is the Hurricanes. It won the British Championship in 2014 after falling short by 2 points in a quarter-final to eventual winners, the London Rebels, the previous year. It is based at Roath Recreational Ground.
The 1958 Commonwealth Games were hosted by Cardiff. These involved 1,130 athletes from 35 national teams competing in 94 events. One of the venues for those Games—The Wales Empire Swimming Pool—was demolished in 1998 to make way for the Principality Stadium. The GBP32m Cardiff International Pool in Cardiff Bay, opened to the public on 12 January 2008 — part of the GBP1bn International Sports Village (ISV) — is the only Olympic-standard swimming pool in Wales. When complete, the ISV complex will provide Olympic standard facilities for sports including boxing and fencing, gymnastics, judo, white water events (including canoeing and kayaking) and wrestling as well as a snow dome with real snow for skiing and snowboarding, an arena for public ice skating and ice hockey and a hotel. Some of the sports facilities at the ISV were to be used as training venues for the London 2012 Olympics.
The Principality Stadium hosts motor-sport events such as the World Rally Championship, as part of Wales Rally GB. The first indoor special stages of the World Rally Championship were held at the Principality Stadium in September 2005 and have been an annual event since. The British Speedway Grand Prix, one of the World Championship events, is held at the Principality Stadium. While the track—a temporary, purpose built, shale oval—is not universally loved, the venue is considered the best of the World Championship's 11 rounds.
The Cardiff International Sports Stadium, opened 19 January 2009, replacing the Cardiff Athletics Stadium, demolished to make way for the Cardiff City Stadium. It has a 4,953 capacity as a multi sport/special event venue, offering certificated international track and field athletics facilities, including an international standard external throws area. The stadium houses the Headquarters of Welsh Athletics, the sport's governing body for Wales. The city's indoor track and field athletics sports venue is the National Indoor Athletics Centre, an international athletics and multi sports centre at the University of Wales Institute, Cardiff Campus, Cyncoed.
Many notable people have hailed from Cardiff, ranging from historical figures such as the 12th-century Welsh leader Ifor Bach to more recent figures such as Roald Dahl, Ken Follett, Griff Rhys Jones, Catrin Dafydd, and the former Blue Peter presenter Gethin Jones.
Notable actors include Ioan Gruffudd (Fantastic 4), Iwan Rheon (Game of Thrones) and Matthew Rhys (The Americans).
Also notable is Siân Grigg, BAFTA winner and Oscar nominated Hollywood make-up artist.
The city has been the birthplace of sports stars such as Tanni Grey-Thompson and Colin Jackson, as well as many Premier League, Football League and international footballers, such as Craig Bellamy, Gareth Bale, Ryan Giggs, Joe Ledley, and former managers of the Wales national football team Terry Yorath and John Toshack. International rugby league players from Cardiff include Frank Whitcombe, Billy Boston, David Willicombe and Colin Dixon. International rugby union players include Sam Warburton, Jamie Roberts, Jamie Robinson, Nicky Robinson, Rhys Patchell, and baseball internationals include George Whitcombe and Ted Peterson.
Saint Teilo (c. 500 – 9 February c. 560) is the patron saint of Cardiff. He was a British Christian monk, bishop, and founder of monasteries and churches. Reputed to be a cousin, friend, and disciple of Saint David, he was Bishop of Llandaff and founder of the first church at Llandaff Cathedral, where his tomb is. His Saint's Day is 9 February.
Cardiff is also well known for its musicians. Ivor Novello inspired the Ivor Novello Awards. Idloes Owen, founder of the Welsh National Opera, lived in Llandaff. Dame Shirley Bassey was born and raised in Cardiff. Charlotte Church is famous as a crossover classical/pop singer. Shakin' Stevens was one of the top-selling male artists in the UK during the 1980s. Tigertailz, a popular glam metal act in the 1980s, also hailed from Cardiff. A number of Cardiff-based bands, such as Catatonia and Super Furry Animals, were popular in the 1990s.
Cardiff-by-the-Sea in Encinitas, California and Cardiff, Alabama were both named after Cardiff in Wales.
A total of 28 countries have a diplomatic presence in Cardiff. Many of these, such as Germany, Italy, Switzerland, Denmark, Canada, Thailand and the Czech Republic, are represented by honorary consulates. The United States Embassy to the UK operates a satellite office.

Located in the southeast of Wales and in the Cardiff Capital Region, Cardiff is the county town of the historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. Cardiff Built-up Area covers a larger area outside the county boundary, including the towns of Dinas Powys and Penarth.",

This sound change probably first occurred in the Middle Ages; both forms were current in the Tudor period. Caerdyf has its origins in post-Roman Brythonic words meaning \"the fort of the Taff\". The fort probably refers to that established by the Romans.

"text": "Until the Roman conquest of Britain, Cardiff was part of the territory of the Silures – a Celtic British tribe that flourished in the Iron Age – whose territory included the areas that would become known as Breconshire, Monmouthshire and Glamorgan. The 3.2 ha (8-acre) fort established by the Romans near the mouth of the River Taff in AD 75, in what would become the north western boundary of the centre of Cardiff, was built over an extensive settlement that had been established by the Romans in the 50s AD. The fort was one of a series of military outposts associated with Isca Augusta (Caerleon) that acted as border defences. The fort may have been abandoned in the early 2nd century as the area had been subdued. However, by this time a civilian settlement, or vicus, was established. It was likely made up of traders who made a living from the fort, ex-soldiers and their families. A Roman villa has been discovered at Ely. Contemporary with the Saxon Shore forts of the 3rd and 4th centuries, a stone fortress was established at Cardiff. Similar to the shore forts, the fortress was built to protect Britannia from raiders. Coins from the reign of Gratian indicate that Cardiff was inhabited until at least the 4th century; the fort was abandoned towards the end of the 4th century, as the last Roman legions left the province of Britannia with Magnus Maximus.",

The current castle is an elaborately decorated Victorian folly designed by William Burges for the Marquess and built in the 1870s, as an occasional retreat. However, the Victorian castle stands on the footings of a much older medieval castle possibly built by Ifor Bach, a regional baron with links to Cardiff Castle also. The exterior has become a popular location for film and television productions. It rarely fulfilled its intended role as a retreat for the Butes, who seldom stayed there. For the Marquess, the pleasure had been in its creation, a pleasure lost following Burges's death in 1881.",

As well as Cardiff Castle and Castell Coch, there are the remains of two motte-and-bailey castles in Morganstown and Rhiwbina, known as Morganstown Castle Mound and Twmpath Castle or Twmpath Motte (also known as Welsh: Caer Cynwrig) respectively. Twmpath being a Welsh word for a small mound), which along with a castle at Whitchurch (known as Treoda and destroyed by housing in the 1960s) formed an arc of fortifications which divided the Norman lordship from the Welsh lordship of Senghenydd. Further up the Cefn Cibwr ridge on the boundary with Caerphilly there is also another ruined castle, known as Morgraig Castle (Welsh: Castell Morgraig). Archaeological evidence suggests this castle was never finished, and it is debated whether the fortification was of Norman or Welsh origin. The concentration of castles indicates the moveable nature of the border between the Norman lordship of Glamorgan, centred at Cardiff, and its Welsh neighbours to the north.",

] | Cardiff is the capital and largest city of Wales. Cardiff had a population of 362,310 in 2021 and forms a principal area officially known as the City and County of Cardiff. The city is the eleventh largest in the United Kingdom. Located in the southeast of Wales and in the Cardiff Capital Region, Cardiff is the county town of the historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. Cardiff Built-up Area covers a larger area outside the county boundary, including the towns of Dinas Powys and Penarth. Cardiff is the main commercial centre of Wales as well as the base for the Senedd, the Welsh Parliament. At the 2021 census, the unitary authority area population was put at 362,400. The population of the wider urban area in 2011 was 479,000. In 2011, it ranked sixth in the world in a National Geographic magazine list of alternative tourist destinations. It is the most popular destination in Wales with 21.3 million visitors in 2017. Cardiff is a major centre for television and film production and is the Welsh base for the main national broadcasters. Cardiff Bay contains the Senedd building and the Wales Millennium Centre arts complex. Work continues at Cardiff Bay and in the centre on projects such as Cardiff International Sports Village, BBC drama village, and a new business district. | 2001-08-17T16:00:58Z | 2023-12-25T01:40:26Z | [

5,884 | Charles Dickens | Charles John Huffam Dickens (/ˈdɪkɪnz/; 7 February 1812 – 9 June 1870) was an English novelist and social critic who created some of the world's best-known fictional characters, and is regarded by many as the greatest novelist of the Victorian era. His works enjoyed unprecedented popularity during his lifetime and, by the 20th century, critics and scholars had recognised him as a literary genius. His novels and short stories are widely read today.
Born in Portsmouth, Dickens left school at the age of 12 to work in a boot-blacking factory when his father John was incarcerated in a debtors' prison. After three years he returned to school, before he began his literary career as a journalist. Dickens edited a weekly journal for 20 years, wrote 15 novels, five novellas, hundreds of short stories and non-fiction articles, lectured and performed readings extensively, was an indefatigable letter writer, and campaigned vigorously for children's rights, for education, and for other social reforms.
Dickens's literary success began with the 1836 serial publication of The Pickwick Papers, a publishing phenomenon—thanks largely to the introduction of the character Sam Weller in the fourth episode—that sparked Pickwick merchandise and spin-offs. Within a few years, Dickens had become an international literary celebrity, famous for his humour, satire and keen observation of character and society. His novels, most of them published in monthly or weekly installments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. Cliffhanger endings in his serial publications kept readers in suspense. The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her own disabilities, Dickens improved the character with positive features. His plots were carefully constructed and he often wove elements from topical events into his narratives. Masses of the illiterate poor would individually pay a halfpenny to have each new monthly episode read to them, opening up and inspiring a new class of readers.
His 1843 novella A Christmas Carol remains especially popular and continues to inspire adaptations in every creative medium. Oliver Twist and Great Expectations are also frequently adapted and, like many of his novels, evoke images of early Victorian London. His 1859 novel A Tale of Two Cities (set in London and Paris) is his best-known work of historical fiction. The most famous celebrity of his era, he undertook, in response to public demand, a series of public reading tours in the later part of his career. The term Dickensian is used to describe something that is reminiscent of Dickens and his writings, such as poor social or working conditions, or comically repulsive characters.
Charles Dickens was born on 7 February 1812 at 1 Mile End Terrace (now 393 Commercial Road), Landport in Portsea Island (Portsmouth), Hampshire, the second of eight children of Elizabeth Dickens (née Barrow; 1789–1863) and John Dickens (1785–1851). His father was a clerk in the Navy Pay Office and was temporarily stationed in the district. He asked Christopher Huffam, rigger to His Majesty's Navy, gentleman, and head of an established firm, to act as godfather to Charles. Huffam is thought to be the inspiration for Paul Dombey, the owner of a shipping company in Dickens's novel Dombey and Son (1848).
In January 1815, John Dickens was called back to London, and the family moved to Norfolk Street, Fitzrovia. When Charles was four, they relocated to Sheerness and thence to Chatham, Kent, where he spent his formative years until the age of 11. His early life seems to have been idyllic, though he thought himself a "very small and not-over-particularly-taken-care-of boy".
Charles spent time outdoors, but also read voraciously, including the picaresque novels of Tobias Smollett and Henry Fielding, as well as Robinson Crusoe and Gil Blas. He read and re-read The Arabian Nights and the Collected Farces of Elizabeth Inchbald. At the age of seven, he first saw Joseph Grimaldi—the father of modern clowning—perform at the Star Theatre, Rochester. He later imitated Grimaldi's clowning on several occasions, and would also edit the Memoirs of Joseph Grimaldi. He retained poignant memories of childhood, helped by an excellent memory of people and events, which he used in his writing. His father's brief work as a clerk in the Navy Pay Office afforded him a few years of private education, first at a dame school and then at a school run by William Giles, a dissenter, in Chatham.
This period came to an end in June 1822, when John Dickens was recalled to Navy Pay Office headquarters at Somerset House and the family (except for Charles, who stayed behind to finish his final term at school) moved to Camden Town in London. The family had left Kent amidst rapidly mounting debts and, living beyond his means, John Dickens was forced by his creditors into the Marshalsea debtors' prison in Southwark, London in 1824. His wife and youngest children joined him there, as was the practice at the time. Charles, then 12 years old, boarded with Elizabeth Roylance, a family friend, at 112 College Place, Camden Town. Mrs Roylance was "a reduced impoverished old lady, long known to our family", whom Dickens later immortalised, "with a few alterations and embellishments", as "Mrs Pipchin" in Dombey and Son. Later, he lived in a back-attic in the house of an agent for the Insolvent Court, Archibald Russell, "a fat, good-natured, kind old gentleman ... with a quiet old wife" and lame son, in Lant Street in Southwark. They provided the inspiration for the Garlands in The Old Curiosity Shop.
On Sundays – with his sister Frances, free from her studies at the Royal Academy of Music – he spent the day at the Marshalsea. Dickens later used the prison as a setting in Little Dorrit. To pay for his board and to help his family, Dickens was forced to leave school and work ten-hour days at Warren's Blacking Warehouse, on Hungerford Stairs, near the present Charing Cross railway station, where he earned six shillings a week pasting labels on pots of boot blacking. The strenuous and often harsh working conditions made a lasting impression on Dickens and later influenced his fiction and essays, becoming the foundation of his interest in the reform of socio-economic and labour conditions, the rigours of which he believed were unfairly borne by the poor. He later wrote that he wondered "how I could have been so easily cast away at such an age". As he recalled to John Forster (from Life of Charles Dickens):
The blacking-warehouse was the last house on the left-hand side of the way, at old Hungerford Stairs. It was a crazy, tumble-down old house, abutting of course on the river, and literally overrun with rats. Its wainscoted rooms, and its rotten floors and staircase, and the old grey rats swarming down in the cellars, and the sound of their squeaking and scuffling coming up the stairs at all times, and the dirt and decay of the place, rise up visibly before me, as if I were there again. The counting-house was on the first floor, looking over the coal-barges and the river. There was a recess in it, in which I was to sit and work. My work was to cover the pots of paste-blacking; first with a piece of oil-paper, and then with a piece of blue paper; to tie them round with a string; and then to clip the paper close and neat, all round, until it looked as smart as a pot of ointment from an apothecary's shop. When a certain number of grosses of pots had attained this pitch of perfection, I was to paste on each a printed label, and then go on again with more pots. Two or three other boys were kept at similar duty down-stairs on similar wages. One of them came up, in a ragged apron and a paper cap, on the first Monday morning, to show me the trick of using the string and tying the knot. His name was Bob Fagin; and I took the liberty of using his name, long afterwards, in Oliver Twist.
When the warehouse was moved to Chandos Street in the smart, busy district of Covent Garden, the boys worked in a room in which the window gave onto the street. Small audiences gathered and watched them at work – in Dickens's biographer Simon Callow's estimation, the public display was "a new refinement added to his misery".
A few months after his imprisonment, John Dickens's mother, Elizabeth Dickens, died and bequeathed him £450. On the expectation of this legacy, Dickens was released from prison. Under the Insolvent Debtors Act, Dickens arranged for payment of his creditors, and he and his family left the Marshalsea, for the home of Mrs Roylance.
Charles's mother, Elizabeth Dickens, did not immediately support his removal from the boot-blacking warehouse. This influenced Dickens's view that a father should rule the family and a mother find her proper sphere inside the home: "I never afterwards forgot, I never shall forget, I never can forget, that my mother was warm for my being sent back." His mother's failure to request his return was a factor in his dissatisfied attitude towards women.
Righteous indignation stemming from his own situation and the conditions under which working-class people lived became major themes of his works, and it was this unhappy period in his youth to which he alluded in his favourite, and most autobiographical, novel, David Copperfield: "I had no advice, no counsel, no encouragement, no consolation, no assistance, no support, of any kind, from anyone, that I can call to mind, as I hope to go to heaven!"
Dickens was eventually sent to the Wellington House Academy in Camden Town, where he remained until March 1827, having spent about two years there. He did not consider it to be a good school: "Much of the haphazard, desultory teaching, poor discipline punctuated by the headmaster's sadistic brutality, the seedy ushers and general run-down atmosphere, are embodied in Mr Creakle's Establishment in David Copperfield."
Dickens worked at the law office of Ellis and Blackmore, attorneys, of Holborn Court, Gray's Inn, as a junior clerk from May 1827 to November 1828. He was a gifted mimic and impersonated those around him: clients, lawyers and clerks. He went to theatres obsessively: he claimed that for at least three years he went to the theatre every day. His favourite actor was Charles Mathews and Dickens learnt his "monopolylogues" (farces in which Mathews played every character) by heart. Then, having learned Gurney's system of shorthand in his spare time, he left to become a freelance reporter. A distant relative, Thomas Charlton, was a freelance reporter at Doctors' Commons and Dickens was able to share his box there to report the legal proceedings for nearly four years. This education was to inform works such as Nicholas Nickleby, Dombey and Son and especially Bleak House, whose vivid portrayal of the machinations and bureaucracy of the legal system did much to enlighten the general public and served as a vehicle for dissemination of Dickens's own views regarding, particularly, the heavy burden on the poor who were forced by circumstances to "go to law".
In 1830, Dickens met his first love, Maria Beadnell, thought to have been the model for the character Dora in David Copperfield. Maria's parents disapproved of the courtship and ended the relationship by sending her to school in Paris.
In 1832, at the age of 20, Dickens was energetic and increasingly self-confident. He enjoyed mimicry and popular entertainment, lacked a clear, specific sense of what he wanted to become, and yet knew he wanted fame. Drawn to the theatre – he became an early member of the Garrick Club – he landed an acting audition at Covent Garden, where the manager George Bartley and the actor Charles Kemble were to see him. Dickens prepared meticulously and decided to imitate the comedian Charles Mathews, but ultimately he missed the audition because of a cold. Before another opportunity arose, he had set out on his career as a writer.
In 1833, Dickens submitted his first story, "A Dinner at Poplar Walk", to the London periodical Monthly Magazine. William Barrow, Dickens's uncle on his mother's side, offered him a job on The Mirror of Parliament and he worked in the House of Commons for the first time early in 1832. He rented rooms at Furnival's Inn and worked as a political journalist, reporting on Parliamentary debates, and he travelled across Britain to cover election campaigns for the Morning Chronicle. His journalism, in the form of sketches in periodicals, formed his first collection of pieces, published in 1836: Sketches by Boz – Boz being a family nickname he employed as a pseudonym for some years. Dickens apparently adopted it from the nickname 'Moses', which he had given to his youngest brother Augustus Dickens, after a character in Oliver Goldsmith's The Vicar of Wakefield. When pronounced by anyone with a head cold, "Moses" became "Boses" – later shortened to Boz. Dickens's own name was considered "queer" by a contemporary critic, who wrote in 1849: "Mr Dickens, as if in revenge for his own queer name, does bestow still queerer ones upon his fictitious creations." Dickens contributed to and edited journals throughout his literary career. In January 1835, the Morning Chronicle launched an evening edition, under the editorship of the Chronicle's music critic, George Hogarth. Hogarth invited him to contribute Street Sketches and Dickens became a regular visitor to his Fulham house – excited by Hogarth's friendship with Walter Scott (whom Dickens greatly admired) and enjoying the company of Hogarth's three daughters: Georgina, Mary and 19-year-old Catherine.
Dickens made rapid progress both professionally and socially. He began a friendship with William Harrison Ainsworth, the author of the highwayman novel Rookwood (1834), whose bachelor salon in Harrow Road had become the meeting place for a set that included Daniel Maclise, Benjamin Disraeli, Edward Bulwer-Lytton and George Cruikshank. All these became his friends and collaborators, with the exception of Disraeli, and he met his first publisher, John Macrone, at the house. The success of Sketches by Boz led to a proposal from publishers Chapman and Hall for Dickens to supply text to match Robert Seymour's engraved illustrations in a monthly letterpress. Seymour committed suicide after the second instalment and Dickens, who wanted to write a connected series of sketches, hired "Phiz" to provide the engravings (which were reduced from four to two per instalment) for the story. The resulting story became The Pickwick Papers and, although the first few episodes were not successful, the introduction of the Cockney character Sam Weller in the fourth episode (the first to be illustrated by Phiz) marked a sharp climb in its popularity. The final instalment sold 40,000 copies. On the impact of the character, The Paris Review stated, "arguably the most historic bump in English publishing is the Sam Weller Bump." A publishing phenomenon, John Sutherland called The Pickwick Papers "[t]he most important single novel of the Victorian era". The unprecedented success led to numerous spin-offs and merchandise including Pickwick cigars, playing cards, china figurines, Sam Weller puzzles, Weller boot polish and joke books.
The Sam Weller Bump testifies not merely to Dickens's comic genius but to his acumen as an "authorpreneur", a portmanteau he inhabited long before The Economist took it up. For a writer who made his reputation crusading against the squalor of the Industrial Revolution, Dickens was a creature of capitalism; he used everything from the powerful new printing presses to the enhanced advertising revenues to the expansion of railroads to sell more books. Dickens ensured that his books were available in cheap bindings for the lower orders as well as in morocco-and-gilt for people of quality; his ideal readership included everyone from the pickpockets who read Oliver Twist to Queen Victoria, who found it "exceedingly interesting".
On the creation of modern mass culture, Nicholas Dames in The Atlantic writes, "'Literature' is not a big enough category for Pickwick. It defined its own, a new one that we have learned to call 'entertainment'." In November 1836, Dickens accepted the position of editor of Bentley's Miscellany, a position he held for three years, until he fell out with the owner. In 1836, as he finished the last instalments of The Pickwick Papers, he began writing the beginning instalments of Oliver Twist – writing as many as 90 pages a month – while continuing work on Bentley's and also writing four plays, the production of which he oversaw. Oliver Twist, published in 1838, became one of Dickens's better known stories and was the first Victorian novel with a child protagonist.
On 2 April 1836, after a one-year engagement, and between episodes two and three of The Pickwick Papers, Dickens married Catherine Thomson Hogarth (1815–1879), the daughter of George Hogarth, editor of the Evening Chronicle. They were married in St Luke's Church, Chelsea, London. After a brief honeymoon in Chalk in Kent, the couple returned to lodgings at Furnival's Inn. The first of their ten children, Charles, was born in January 1837 and a few months later the family set up home in Bloomsbury at 48 Doughty Street, London (on which Charles had a three-year lease at £80 a year) from 25 March 1837 until December 1839. Dickens's younger brother Frederick and Catherine's 17-year-old sister Mary Hogarth moved in with them. Dickens became very attached to Mary, and she died in his arms after a brief illness in 1837. Unusually for Dickens, as a consequence of his shock, he stopped working, and he and Catherine stayed at a little farm on Hampstead Heath for a fortnight. Dickens idealised Mary; the character he fashioned after her, Rose Maylie, he found he could not now kill, as he had planned, in his fiction, and, according to Ackroyd, he drew on memories of her for his later descriptions of Little Nell and Florence Dombey. His grief was so great that he was unable to meet the deadline for the June instalment of The Pickwick Papers and had to cancel the Oliver Twist instalment that month as well. The time in Hampstead was the occasion for a growing bond between Dickens and John Forster to develop; Forster soon became his unofficial business manager and the first to read his work.
His success as a novelist continued. The young Queen Victoria read both Oliver Twist and The Pickwick Papers, staying up until midnight to discuss them. Nicholas Nickleby (1838–39), The Old Curiosity Shop (1840–41) and, finally, his first historical novel, Barnaby Rudge: A Tale of the Riots of 'Eighty, as part of the Master Humphrey's Clock series (1840–41), were all published in monthly instalments before being made into books.
In the midst of all his activity during this period, there was discontent with his publishers and John Macrone was bought off, while Richard Bentley signed over all his rights in Oliver Twist. Other signs of a certain restlessness and discontent emerged; in Broadstairs he flirted with Eleanor Picken, the young fiancée of his solicitor's best friend and one night grabbed her and ran with her down to the sea. He declared they were both to drown there in the "sad sea waves". She finally got free, and afterwards kept her distance. In June 1841, he precipitously set out on a two-month tour of Scotland and then, in September 1841, telegraphed Forster that he had decided to go to America. Master Humphrey's Clock was shut down, though Dickens was still keen on the idea of the weekly magazine, a form he liked, an appreciation that had begun with his childhood reading of the 18th-century magazines Tatler and The Spectator.
Dickens was perturbed by the return to power of the Tories, whom he described as "people whom, politically, I despise and abhor." He had been tempted to stand for the Liberals in Reading, but decided against it due to financial straits. He wrote three anti-Tory verse satires ("The Fine Old English Gentleman", "The Quack Doctor's Proclamation", and "Subjects for Painters") which were published in The Examiner.
On 22 January 1842, Dickens and his wife arrived in Boston, Massachusetts, aboard the RMS Britannia during their first trip to the United States and Canada. At this time Georgina Hogarth, another sister of Catherine, joined the Dickens household, now living at Devonshire Terrace, Marylebone to care for the young family they had left behind. She remained with them as housekeeper, organiser, adviser and friend until Dickens's death in 1870. Dickens modelled the character of Agnes Wickfield after Georgina and Mary.
He described his impressions in a travelogue, American Notes for General Circulation. In Notes, Dickens includes a powerful condemnation of slavery which he had attacked as early as The Pickwick Papers, correlating the emancipation of the poor in England with the abolition of slavery abroad citing newspaper accounts of runaway slaves disfigured by their masters. In spite of the abolitionist sentiments gleaned from his trip to America, some modern commentators have pointed out inconsistencies in Dickens's views on racial inequality. For instance, he has been criticised for his subsequent acquiescence in Governor Eyre's harsh crackdown during the 1860s Morant Bay rebellion in Jamaica and his failure to join other British progressives in condemning it. From Richmond, Virginia, Dickens returned to Washington, D.C., and started a trek westward, with brief pauses in Cincinnati and Louisville, to St. Louis, Missouri. While there, he expressed a desire to see an American prairie before returning east. A group of 13 men then set out with Dickens to visit Looking Glass Prairie, a trip 30 miles into Illinois.
During his American visit, Dickens spent a month in New York City, giving lectures, raising the question of international copyright laws and the pirating of his work in America. He persuaded a group of 25 writers, headed by Washington Irving, to sign a petition for him to take to Congress, but the press were generally hostile to this, saying that he should be grateful for his popularity and that it was mercenary to complain about his work being pirated.
The popularity he gained caused a shift in his self-perception according to critic Kate Flint, who writes that he "found himself a cultural commodity, and its circulation had passed out his control", causing him to become interested in and delve into themes of public and personal personas in the next novels. She writes that he assumed a role of "influential commentator", publicly and in his fiction, evident in his next few books. His trip to the U.S. ended with a trip to Canada – Niagara Falls, Toronto, Kingston and Montreal – where he appeared on stage in light comedies.
Soon after his return to England, Dickens began work on the first of his Christmas stories, A Christmas Carol, written in 1843, which was followed by The Chimes in 1844 and The Cricket on the Hearth in 1845. Of these, A Christmas Carol was most popular and, tapping into an old tradition, did much to promote a renewed enthusiasm for the joys of Christmas in Britain and America. The seeds for the story became planted in Dickens's mind during a trip to Manchester to witness the conditions of the manufacturing workers there. This, along with scenes he had recently witnessed at the Field Lane Ragged School, caused Dickens to resolve to "strike a sledge hammer blow" for the poor. As the idea for the story took shape and the writing began in earnest, Dickens became engrossed in the book. He later wrote that as the tale unfolded he "wept and laughed, and wept again" as he "walked about the black streets of London fifteen or twenty miles many a night when all sober folks had gone to bed".
After living briefly in Italy (1844), Dickens travelled to Switzerland (1846), where he began work on Dombey and Son (1846–48). This and David Copperfield (1849–50) mark a significant artistic break in Dickens's career as his novels became more serious in theme and more carefully planned than his early works.
At about this time, he was made aware of a large embezzlement at the firm where his brother, Augustus, worked (John Chapman & Co). It had been carried out by Thomas Powell, a clerk, who was on friendly terms with Dickens and who had acted as mentor to Augustus when he started work. Powell was also an author and poet and knew many of the famous writers of the day. After further fraudulent activities, Powell fled to New York and published a book called The Living Authors of England with a chapter on Charles Dickens, who was not amused by what Powell had written. One item that seemed to have annoyed him was the assertion that he had based the character of Paul Dombey (Dombey and Son) on Thomas Chapman, one of the principal partners at John Chapman & Co. Dickens immediately sent a letter to Lewis Gaylord Clark, editor of the New York literary magazine The Knickerbocker, saying that Powell was a forger and thief. Clark published the letter in the New-York Tribune and several other papers picked up on the story. Powell began proceedings to sue these publications and Clark was arrested. Dickens, realising that he had acted in haste, contacted John Chapman & Co to seek written confirmation of Powell's guilt. Dickens did receive a reply confirming Powell's embezzlement, but once the directors realised this information might have to be produced in court, they refused to make further disclosures. Owing to the difficulties of providing evidence in America to support his accusations, Dickens eventually made a private settlement with Powell out of court.
Angela Burdett Coutts, heir to the Coutts banking fortune, approached Dickens in May 1846 about setting up a home for the redemption of fallen women of the working class. Coutts envisioned a home that would replace the punitive regimes of existing institutions with a reformative environment conducive to education and proficiency in domestic household chores. After initially resisting, Dickens eventually founded the home, named Urania Cottage, in the Lime Grove area of Shepherd's Bush, which he managed for ten years, setting the house rules, reviewing the accounts and interviewing prospective residents. Emigration and marriage were central to Dickens's agenda for the women on leaving Urania Cottage, from which it is estimated that about 100 women graduated between 1847 and 1859.
As a young man, Dickens expressed a distaste for certain aspects of organised religion. In 1836, in a pamphlet titled Sunday Under Three Heads, he defended the people's right to pleasure, opposing a plan to prohibit games on Sundays. "Look into your churches – diminished congregations and scanty attendance. People have grown sullen and obstinate, and are becoming disgusted with the faith which condemns them to such a day as this, once in every seven. They display their feeling by staying away [from church]. Turn into the streets [on a Sunday] and mark the rigid gloom that reigns over everything around."
Dickens honoured the figure of Jesus Christ. He is regarded as a professing Christian. His son, Henry Fielding Dickens, described him as someone who "possessed deep religious convictions". In the early 1840s, he had shown an interest in Unitarian Christianity and Robert Browning remarked that "Mr Dickens is an enlightened Unitarian." Professor Gary Colledge has written that he "never strayed from his attachment to popular lay Anglicanism". Dickens authored a work called The Life of Our Lord (1846), a book about the life of Christ, written with the purpose of sharing his faith with his children and family. In a scene from David Copperfield, Dickens echoed Geoffrey Chaucer's use of Luke 23:34 from Troilus and Criseyde (Dickens held a copy in his library), with G. K. Chesterton writing, "among the great canonical English authors, Chaucer and Dickens have the most in common."
Dickens disapproved of Roman Catholicism and 19th-century evangelicalism, seeing both as extremes of Christianity and likely to limit personal expression, and was critical of what he saw as the hypocrisy of religious institutions and philosophies like spiritualism, all of which he considered deviations from the true spirit of Christianity, as shown in the book he wrote for his family in 1846. While Dickens advocated equal rights for Catholics in England, he strongly disliked how individual civil liberties were often threatened in countries where Catholicism predominated and referred to the Catholic Church as "that curse upon the world." Dickens also rejected the Evangelical conviction that the Bible was the infallible word of God. His ideas on Biblical interpretation were similar to the Liberal Anglican Arthur Penrhyn Stanley's doctrine of "progressive revelation". Leo Tolstoy and Fyodor Dostoyevsky referred to Dickens as "that great Christian writer".
In December 1845, Dickens took up the editorship of the London-based Daily News, a liberal paper through which Dickens hoped to advocate, in his own words, "the Principles of Progress and Improvement, of Education and Civil and Religious Liberty and Equal Legislation." Among the other contributors Dickens chose to write for the paper were the radical economist Thomas Hodgskin and the social reformer Douglas William Jerrold, who frequently attacked the Corn Laws. Dickens lasted only ten weeks on the job before resigning due to a combination of exhaustion and frustration with one of the paper's co-owners.
A Francophile, Dickens often holidayed in France and, in a speech delivered in Paris in 1846 in French, called the French "the first people in the universe". During his visit to Paris, Dickens met the French literati Alexandre Dumas, Victor Hugo, Eugène Scribe, Théophile Gautier, François-René de Chateaubriand and Eugène Sue. In early 1849, Dickens started to write David Copperfield. It was published between 1849 and 1850. In Dickens's biography, Life of Charles Dickens (1872), John Forster wrote of David Copperfield, "underneath the fiction lay something of the author's life". It was Dickens's personal favourite among his novels, as he wrote in the author's preface to the 1867 edition of the novel.
In late November 1851, Dickens moved into Tavistock House where he wrote Bleak House (1852–53), Hard Times (1854) and Little Dorrit (1856). It was here that he indulged in the amateur theatricals described in Forster's Life of Charles Dickens. During this period, he worked closely with the novelist and playwright Wilkie Collins. In 1856, his income from writing allowed him to buy Gads Hill Place in Higham, Kent. As a child, Dickens had walked past the house and dreamed of living in it. The area was also the scene of some of the events of Shakespeare's Henry IV, Part 1 and this literary connection pleased him.
During this time Dickens was also the publisher, editor and a major contributor to the journals Household Words (1850–1859) and All the Year Round (1858–1870). In 1854, at the behest of Sir John Franklin's widow Lady Jane, Dickens viciously attacked Arctic explorer John Rae in Household Words for his report to the Admiralty, based on interviews with local Inuit, that the members of Franklin's lost expedition had resorted to cannibalism. These attacks would later be expanded on his 1856 play The Frozen Deep, which satirizes Rae and the Inuit. 20th century archaeology work in King William Island later confirmed that the members of the Franklin expedition resorted to cannibalism.
In 1855, when Dickens's good friend and Liberal MP Austen Henry Layard formed an Administrative Reform Association to demand significant reforms of Parliament, Dickens joined and volunteered his resources in support of Layard's cause. With the exception of Lord John Russell, who was the only leading politician in whom Dickens had any faith and to whom he later dedicated A Tale of Two Cities, Dickens believed that the political aristocracy and their incompetence were the death of England. When he and Layard were accused of fomenting class conflict, Dickens replied that the classes were already in opposition and the fault was with the aristocratic class. Dickens used his pulpit in Household Words to champion the Reform Association. He also commented on foreign affairs, declaring his support for Giuseppe Garibaldi and Giuseppe Mazzini, helping raise funds for their campaigns and stating that "a united Italy would be of vast importance to the peace of the world, and would be a rock in Louis Napoleon's way," and that "I feel for Italy almost as if I were an Italian born." Dickens also published dozens of writings in Household Words supporting vaccination, including multiple laudations for vaccine pioneer Edward Jenner.
Following the Indian Mutiny of 1857, Dickens joined in the widespread criticism of the East India Company for its role in the event, but reserved his fury for Indians, wishing that he was the commander-in-chief in India so that he would be able to "do my utmost to exterminate the Race upon whom the stain of the late cruelties rested."
In 1857, Dickens hired professional actresses for The Frozen Deep, which he and his protégé Wilkie Collins had written. Dickens fell in love with one of the actresses, Ellen Ternan, and this passion was to last the rest of his life. In 1858, when Dickens was 45 and Ternan 18, divorce would have been scandalous for someone of his fame. After publicly accusing Catherine of not loving their children and suffering from "a mental disorder" – statements that disgusted his contemporaries, including Elizabeth Barrett Browning – Dickens attempted to have Catherine institutionalized. When his scheme failed, they separated. Catherine left, never to see her husband again, taking with her one child. Her sister Georgina, who stayed at Gads Hill, raised the other children.
During this period, whilst pondering a project to give public readings for his own profit, Dickens was approached through a charitable appeal by Great Ormond Street Hospital to help it survive its first major financial crisis. His "Drooping Buds" essay in Household Words earlier on 3 April 1852 was considered by the hospital's founders to have been the catalyst for the hospital's success. Dickens, whose philanthropy was well-known, was asked by his friend, the hospital's founder Charles West, to preside over the appeal, and he threw himself into the task, heart and soul. Dickens's public readings secured sufficient funds for an endowment to put the hospital on a sound financial footing; one reading on 9 February 1858 alone raised £3,000.
After separating from Catherine, Dickens undertook a series of popular and remunerative reading tours which, together with his journalism, were to absorb most of his creative energies for the next decade, in which he was to write only two novels. His first reading tour, lasting from April 1858 to February 1859, consisted of 129 appearances in 49 towns throughout England, Scotland and Ireland. Dickens's continued fascination with the theatrical world was written into the theatre scenes in Nicholas Nickleby, and he found an outlet in public readings. In 1866, he undertook a series of public readings in England and Scotland, with more the following year in England and Ireland.
Other works soon followed, including A Tale of Two Cities (1859) and Great Expectations (1861), which were resounding successes. Set in London and Paris, A Tale of Two Cities is his best-known work of historical fiction and includes the famous opening sentence that begins with "It was the best of times, it was the worst of times." It is regularly touted as one of the best-selling novels of all time. Themes in Great Expectations include wealth and poverty, love and rejection, and the eventual triumph of good over evil.
In early September 1860, in a field behind Gads Hill, Dickens made a bonfire of most of his correspondence; he spared only letters on business matters. Since Ellen Ternan also destroyed all of his letters to her, the extent of the affair between the two remains speculative. In the 1930s, Thomas Wright recounted that Ternan had unburdened herself to a Canon Benham and gave currency to rumours they had been lovers. Dickens's daughter, Kate Perugini, stated that the two had a son who died in infancy to biographer Gladys Storey in an interview before the former's death in 1929. Storey published her account in Dickens and Daughter, though no contemporary evidence was given. On his death, Dickens settled an annuity on Ternan which made her financially independent. Claire Tomalin's book The Invisible Woman argues that Ternan lived with Dickens secretly for the last 13 years of his life. The book was subsequently turned into a play, Little Nell, by Simon Gray, and a 2013 film. During the same period Dickens furthered his interest in the paranormal becoming one of the early members of The Ghost Club.
In June 1862, he was offered £10,000 for a reading tour of Australia. He was enthusiastic, and even planned a travel book, The Uncommercial Traveller Upside Down, but ultimately decided against the tour. Two of his sons, Alfred D'Orsay Tennyson Dickens and Edward Bulwer Lytton Dickens, migrated to Australia, Edward becoming a member of the Parliament of New South Wales as Member for Wilcannia between 1889 and 1894.
On 9 June 1865, while returning from Paris with Ellen Ternan, Dickens was involved in the Staplehurst rail crash in Kent. The train's first seven carriages plunged off a cast iron bridge that was under repair. The only first-class carriage to remain on the track was the one in which Dickens was travelling. Before rescuers arrived, Dickens tended and comforted the wounded and the dying with a flask of brandy and a hat refreshed with water, and saved some lives. Before leaving, he remembered the unfinished manuscript for Our Mutual Friend, and he returned to his carriage to retrieve it.
Dickens later used the experience of the crash as material for his short ghost story, "The Signal-Man", in which the central character has a premonition of his own death in a rail crash. He also based the story on several previous rail accidents, such as the Clayton Tunnel rail crash in Sussex of 1861. Dickens managed to avoid an appearance at the inquest to avoid disclosing that he had been travelling with Ternan and her mother, which would have caused a scandal. After the crash, Dickens was nervous when travelling by train and would use alternative means when available. In 1868 he wrote, "I have sudden vague rushes of terror, even when riding in a hansom cab, which are perfectly unreasonable but quite insurmountable." Dickens's son, Henry, recalled, "I have seen him sometimes in a railway carriage when there was a slight jolt. When this happened he was almost in a state of panic and gripped the seat with both hands."
While he contemplated a second visit to the United States, the outbreak of the Civil War in America in 1861 delayed his plans. On 9 November 1867, over two years after the war, Dickens set sail from Liverpool for his second American reading tour. Landing in Boston, he devoted the rest of the month to a round of dinners with such notables as Ralph Waldo Emerson, Henry Wadsworth Longfellow and his American publisher, James T. Fields. In early December, the readings began. He performed 76 readings, netting £19,000, from December 1867 to April 1868. Dickens shuttled between Boston and New York, where he gave 22 readings at Steinway Hall. Although he had started to suffer from what he called the "true American catarrh", he kept to a schedule that would have challenged a much younger man, even managing to squeeze in some sleighing in Central Park.
During his travels, he saw a change in the people and the circumstances of America. His final appearance was at a banquet the American Press held in his honour at Delmonico's on 18 April, when he promised never to denounce America again. By the end of the tour Dickens could hardly manage solid food, subsisting on champagne and eggs beaten in sherry. On 23 April he boarded the Cunard liner Russia to return to Britain, barely escaping a federal tax lien against the proceeds of his lecture tour.
In 1868–69, Dickens gave a series of "farewell readings" in England, Scotland and Ireland, beginning on 6 October. He managed, of a contracted 100 readings, to give 75 in the provinces, with a further 12 in London. As he pressed on he was affected by giddiness and fits of paralysis. He had a stroke on 18 April 1869 in Chester. He collapsed on 22 April 1869, at Preston, Lancashire; on doctor's advice, the tour was cancelled. After further provincial readings were cancelled, he began work on his final novel, The Mystery of Edwin Drood. It was fashionable in the 1860s to 'do the slums' and, in company, Dickens visited opium dens in Shadwell, where he witnessed an elderly addict called "Laskar Sal", who formed the model for "Opium Sal" in Edwin Drood.
After Dickens regained enough strength, he arranged, with medical approval, for a final series of readings to partly make up to his sponsors what they had lost due to his illness. There were 12 performances, on 11 January to 15 March 1870; the last at 8:00pm at St. James's Hall, London. Though in grave health by then, he read A Christmas Carol and The Trial from Pickwick. On 2 May, he made his last public appearance at a Royal Academy banquet in the presence of the Prince and Princess of Wales, paying a special tribute on the death of his friend, illustrator Daniel Maclise.
On 8 June 1870, Dickens had another stroke at his home after a full day's work on Edwin Drood. He never regained consciousness. The next day, he died at Gads Hill Place. Biographer Claire Tomalin has suggested Dickens was actually in Peckham when he had had the stroke and his mistress Ellen Ternan and her maids had him taken back to Gads Hill so that the public would not know the truth about their relationship. Contrary to his wish to be buried at Rochester Cathedral "in an inexpensive, unostentatious, and strictly private manner", he was laid to rest in the Poets' Corner of Westminster Abbey. A printed epitaph circulated at the time of the funeral reads:
To the Memory of Charles Dickens (England's most popular author) who died at his residence, Higham, near Rochester, Kent, 9 June 1870, aged 58 years. He was a sympathiser with the poor, the suffering, and the oppressed; and by his death, one of England's greatest writers is lost to the world.
A letter from Dickens to the Clerk of the Privy Council in March indicates he'd been offered and accepted a baronetcy, which was not gazetted before his death. His last words were "On the ground" in response to his sister-in-law Georgina's request that he lie down. On Sunday, 19 June 1870, five days after Dickens was buried in the Abbey, Dean Arthur Penrhyn Stanley delivered a memorial elegy, lauding "the genial and loving humorist whom we now mourn", for showing by his own example "that even in dealing with the darkest scenes and the most degraded characters, genius could still be clean, and mirth could be innocent". Pointing to the fresh flowers that adorned the novelist's grave, Stanley assured those present that "the spot would thenceforth be a sacred one with both the New World and the Old, as that of the representative of literature, not of this island only, but of all who speak our English tongue."
In his will, drafted more than a year before his death, Dickens left the care of his £80,000 estate (£8,143,500 in 2021) to his long-time colleague John Forster and his "best and truest friend" Georgina Hogarth who, along with Dickens's two sons, also received a tax-free sum of £8,000 (equivalent to £814,000 in 2021). He left Caroline an annual income of £600 (£61,100 in 2021) and made her similar allowances in his will. He bequeathed £19 19s (£2,000 in 2021) to each servant in his employment at the time of his death.
Dickens's approach to the novel is influenced by various things, including the picaresque novel tradition, melodrama and the novel of sensibility. According to Ackroyd, other than these, perhaps the most important literary influence on him was derived from the fables of The Arabian Nights. Satire and irony are central to the picaresque novel. Comedy is also an aspect of the British picaresque novel tradition of Laurence Sterne, Henry Fielding and Tobias Smollett. Fielding's Tom Jones was a major influence on the 19th-century novelist including Dickens, who read it in his youth and named a son Henry Fielding Dickens after him. Influenced by Gothic fiction—a literary genre that began with The Castle of Otranto (1764) by Horace Walpole—Dickens incorporated Gothic imagery, settings and plot devices in his works. Victorian gothic moved from castles and abbeys into contemporary urban environments: in particular London, such as Dickens's Oliver Twist and Bleak House. The jilted bride Miss Havisham from Great Expectations is one of Dickens's best-known gothic creations; living in a ruined mansion, her bridal gown effectively doubles as her funeral shroud.
No other writer had such a profound influence on Dickens as William Shakespeare. On Dickens's veneration of Shakespeare, Alfred Harbage wrote in A Kind of Power: The Shakespeare-Dickens Analogy (1975) that "No one is better qualified to recognise literary genius than a literary genius". Regarding Shakespeare as "the great master" whose plays "were an unspeakable source of delight", Dickens's lifelong affinity with the playwright included seeing theatrical productions of his plays in London and putting on amateur dramatics with friends in his early years. In 1838, Dickens travelled to Stratford-upon-Avon and visited the house in which Shakespeare was born, leaving his autograph in the visitors' book. Dickens would draw on this experience in his next work, Nicholas Nickleby (1838–39), expressing the strength of feeling experienced by visitors to Shakespeare's birthplace: the character Mrs Wititterly states, "I don't know how it is, but after you've seen the place and written your name in the little book, somehow or other you seem to be inspired; it kindles up quite a fire within one."
Dickens's writing style is marked by a profuse linguistic creativity. Satire, flourishing in his gift for caricature, is his forte. An early reviewer compared him to Hogarth for his keen practical sense of the ludicrous side of life, though his acclaimed mastery of varieties of class idiom may in fact mirror the conventions of contemporary popular theatre. Dickens worked intensively on developing arresting names for his characters that would reverberate with associations for his readers and assist the development of motifs in the storyline, giving what one critic calls an "allegorical impetus" to the novels' meanings. To cite one of numerous examples, the name Mr Murdstone in David Copperfield conjures up twin allusions to murder and stony coldness. His literary style is also a mixture of fantasy and realism. His satires of British aristocratic snobbery – he calls one character the "Noble Refrigerator" – are often popular. Comparing orphans to stocks and shares, people to tug boats or dinner-party guests to furniture are just some of Dickens's acclaimed flights of fancy.
The author worked closely with his illustrators, supplying them with a summary of the work at the outset and thus ensuring that his characters and settings were exactly how he envisioned them. He briefed the illustrator on plans for each month's instalment so that work could begin before he wrote them. Marcus Stone, illustrator of Our Mutual Friend, recalled that the author was always "ready to describe down to the minutest details the personal characteristics, and ... life-history of the creations of his fancy". Dickens employs Cockney English in many of his works, denoting working-class Londoners. Cockney grammar appears in terms such as ain't, and consonants in words are frequently omitted, as in 'ere (here) and wot (what). An example of this usage is in Oliver Twist. The Artful Dodger uses cockney slang which is juxtaposed with Oliver's 'proper' English, when the Dodger repeats Oliver saying "seven" with "sivin".
Dickens's biographer Claire Tomalin regards him as the greatest creator of character in English fiction after Shakespeare. Dickensian characters are amongst the most memorable in English literature, especially so because of their typically whimsical names. The likes of Ebenezer Scrooge, Tiny Tim, Jacob Marley and Bob Cratchit (A Christmas Carol); Oliver Twist, The Artful Dodger, Fagin and Bill Sikes (Oliver Twist); Pip, Miss Havisham and Abel Magwitch (Great Expectations); Sydney Carton, Charles Darnay and Madame Defarge (A Tale of Two Cities); David Copperfield, Uriah Heep and Mr Micawber (David Copperfield); Daniel Quilp and Nell Trent (The Old Curiosity Shop), Samuel Pickwick and Sam Weller (The Pickwick Papers); and Wackford Squeers (Nicholas Nickleby) are so well known as to be part and parcel of popular culture, and in some cases have passed into ordinary language: a scrooge, for example, is a miser or someone who dislikes Christmas festivity.
His characters were often so memorable that they took on a life of their own outside his books. "Gamp" became a slang expression for an umbrella from the character Mrs Gamp, and "Pickwickian", "Pecksniffian" and "Gradgrind" all entered dictionaries due to Dickens's original portraits of such characters who were, respectively, quixotic, hypocritical and vapidly factual. The character that made Dickens famous, Sam Weller became known for his Wellerisms—one-liners that turned proverbs on their heads. Many were drawn from real life: Mrs Nickleby is based on his mother, although she did not recognise herself in the portrait, just as Mr Micawber is constructed from aspects of his father's 'rhetorical exuberance'; Harold Skimpole in Bleak House is based on James Henry Leigh Hunt; his wife's dwarfish chiropodist recognised herself in Miss Mowcher in David Copperfield. Perhaps Dickens's impressions on his meeting with Hans Christian Andersen informed the delineation of Uriah Heep (a term synonymous with sycophant).
Virginia Woolf maintained that "we remodel our psychological geography when we read Dickens" as he produces "characters who exist not in detail, not accurately or exactly, but abundantly in a cluster of wild yet extraordinarily revealing remarks". T. S. Eliot wrote that Dickens "excelled in character; in the creation of characters of greater intensity than human beings". One "character" vividly drawn throughout his novels is London itself. Dickens described London as a magic lantern, inspiring the places and people in many of his novels. From the coaching inns on the outskirts of the city to the lower reaches of the Thames, all aspects of the capital – Dickens's London – are described over the course of his body of work. Walking the streets (particularly around London) formed an integral part of his writing life, stoking his creativity. Dickens was known to regularly walk at least a dozen miles (19 km) per day, and once wrote, "If I couldn't walk fast and far, I should just explode and perish."
Authors frequently draw their portraits of characters from people they have known in real life. David Copperfield is regarded by many as a veiled autobiography of Dickens. The scenes of interminable court cases and legal arguments in Bleak House reflect Dickens's experiences as a law clerk and court reporter, and in particular his direct experience of the law's procedural delay during 1844 when he sued publishers in Chancery for breach of copyright. Dickens's father was sent to prison for debt, and this became a common theme in many of his books, with the detailed depiction of life in the Marshalsea prison in Little Dorrit resulting from Dickens's own experiences of the institution. Lucy Stroughill, a childhood sweetheart, may have affected several of Dickens's portraits of girls such as Little Em'ly in David Copperfield and Lucie Manette in A Tale of Two Cities.
Dickens may have drawn on his childhood experiences, but he was also ashamed of them and would not reveal that this was where he gathered his realistic accounts of squalor. Very few knew the details of his early life until six years after his death, when John Forster published a biography on which Dickens had collaborated. Though Skimpole brutally sends up Leigh Hunt, some critics have detected in his portrait features of Dickens's own character, which he sought to exorcise by self-parody.
A pioneer of the serial publication of narrative fiction, Dickens wrote most of his major novels in monthly or weekly instalments in journals such as Master Humphrey's Clock and Household Words, later reprinted in book form. These instalments made the stories affordable and accessible, with the audience more evenly distributed across income levels than previous. His instalment format inspired a narrative that he would explore and develop throughout his career, and the regular cliffhangers made each new episode widely anticipated. When The Old Curiosity Shop was being serialised, American fans waited at the docks in New York harbour, shouting out to the crew of an incoming British ship, "Is little Nell dead?" Dickens was able to incorporate this episodic writing style but still end up with a coherent novel at the end.
Another important impact of Dickens's episodic writing style resulted from his exposure to the opinions of his readers and friends. His friend Forster had a significant hand in reviewing his drafts, an influence that went beyond matters of punctuation; he toned down melodramatic and sensationalist exaggerations, cut long passages (such as the episode of Quilp's drowning in The Old Curiosity Shop), and made suggestions about plot and character. It was he who suggested that Charley Bates should be redeemed in Oliver Twist. Dickens had not thought of killing Little Nell and it was Forster who advised him to entertain this possibility as necessary to his conception of the heroine.
At the helm in popularising cliffhangers and serial publications in Victorian literature, Dickens's influence can also be seen in television soap operas and film series, with The Guardian stating that "the DNA of Dickens's busy, episodic storytelling, delivered in instalments and rife with cliffhangers and diversions, is traceable in everything." His serialisation of his novels also drew comments from other writers. In Scottish author Robert Louis Stevenson's novel The Wrecker, Captain Nares, investigating an abandoned ship, remarked: "See! They were writing up the log," said Nares, pointing to the ink-bottle. "Caught napping, as usual. I wonder if there ever was a captain yet that lost a ship with his log-book up to date? He generally has about a month to fill up on a clean break, like Charles Dickens and his serial novels."
Dickens's novels were, among other things, works of social commentary. Simon Callow states, "From the moment he started to write, he spoke for the people, and the people loved him for it." He was a fierce critic of the poverty and social stratification of Victorian society. In a New York address, he expressed his belief that "Virtue shows quite as well in rags and patches as she does in purple and fine linen". Dickens's second novel, Oliver Twist (1839), shocked readers with its images of poverty and crime: it challenged middle class polemics about criminals, making impossible any pretence to ignorance about what poverty entailed.
At a time when Britain was the major economic and political power of the world, Dickens highlighted the life of the forgotten poor and disadvantaged within society. Through his journalism he campaigned on specific issues – such as sanitation and the workhouse – but his fiction probably demonstrated its greatest prowess in changing public opinion in regard to class inequalities. He often depicted the exploitation and oppression of the poor and condemned the public officials and institutions that not only allowed such abuses to exist, but flourished as a result. His most strident indictment of this condition is in Hard Times (1854), Dickens's only novel-length treatment of the industrial working class. In this work, he uses vitriol and satire to illustrate how this marginalised social stratum was termed "Hands" by the factory owners; that is, not really "people" but rather only appendages of the machines they operated. His writings inspired others, in particular journalists and political figures, to address such problems of class oppression. For example, the prison scenes in The Pickwick Papers are claimed to have been influential in having the Fleet Prison shut down. Karl Marx asserted that Dickens "issued to the world more political and social truths than have been uttered by all the professional politicians, publicists and moralists put together". George Bernard Shaw even remarked that Great Expectations was more seditious than Marx's Das Kapital. The exceptional popularity of Dickens's novels, even those with socially oppositional themes (Bleak House, 1853; Little Dorrit, 1857; Our Mutual Friend, 1865), not only underscored his ability to create compelling storylines and unforgettable characters, but also ensured that the Victorian public confronted issues of social justice that had commonly been ignored.
It has been argued that his technique of flooding his narratives with an 'unruly superfluity of material' that, in the gradual dénouement, yields up an unsuspected order, influenced the organisation of Charles Darwin's On the Origin of Species.
Dickens is often described as using idealised characters and highly sentimental scenes to contrast with his caricatures and the ugly social truths he reveals. The story of Nell Trent in The Old Curiosity Shop (1841) was received as extraordinarily moving by contemporary readers but viewed as ludicrously sentimental by Oscar Wilde. "One must have a heart of stone to read the death of little Nell", he said in a famous remark, "without dissolving into tears ... of laughter." G. K. Chesterton stated, "It is not the death of little Nell, but the life of little Nell, that I object to", arguing that the maudlin effect of his description of her life owed much to the gregarious nature of Dickens's grief, his "despotic" use of people's feelings to move them to tears in works like this.
The question as to whether Dickens belongs to the tradition of the sentimental novel is debatable. Valerie Purton, in her book Dickens and the Sentimental Tradition, sees him continuing aspects of this tradition, and argues that his "sentimental scenes and characters [are] as crucial to the overall power of the novels as his darker or comic figures and scenes", and that "Dombey and Son is [ ... ] Dickens's greatest triumph in the sentimentalist tradition". The Encyclopædia Britannica online comments that, despite "patches of emotional excess", such as the reported death of Tiny Tim in A Christmas Carol (1843), "Dickens cannot really be termed a sentimental novelist".
In Oliver Twist Dickens provides readers with an idealised portrait of a boy so inherently and unrealistically good that his values are never subverted by either brutal orphanages or coerced involvement in a gang of young pickpockets. While later novels also centre on idealised characters (Esther Summerson in Bleak House and Amy Dorrit in Little Dorrit), this idealism serves only to highlight Dickens's goal of poignant social commentary. Dickens's fiction, reflecting what he believed to be true of his own life, makes frequent use of coincidence, either for comic effect or to emphasise the idea of providence. For example, Oliver Twist turns out to be the lost nephew of the upper-class family that rescues him from the dangers of the pickpocket group. Such coincidences are a staple of 18th-century picaresque novels, such as Henry Fielding's Tom Jones, which Dickens enjoyed reading as a youth.
Dickens was the most popular novelist of his time, and remains one of the best-known and most-read of English authors. His works have never gone out of print, and have been adapted continually for the screen since the invention of cinema, with at least 200 motion pictures and TV adaptations based on Dickens's works documented. Many of his works were adapted for the stage during his own lifetime – early productions included The Haunted Man which was performed in the West End's Adelphi Theatre in 1848 – and, as early as 1901, the British silent film Scrooge, or, Marley's Ghost was made by Walter R. Booth. Contemporaries such as publisher Edward Lloyd cashed in on Dickens's popularity with cheap imitations of his novels, resulting in his own popular 'penny dreadfuls'.
Dickens created some of the world's best-known fictional characters and is regarded by many as the greatest British novelist of the Victorian era. From the beginning of his career in the 1830s, his achievements in English literature were compared to those of Shakespeare. Dickens's literary reputation, however, began to decline with the publication of Bleak House in 1852–53. Philip Collins calls Bleak House "a crucial item in the history of Dickens's reputation. Reviewers and literary figures during the 1850s, 1860s and 1870s, saw a 'drear decline' in Dickens, from a writer of 'bright sunny comedy ... to dark and serious social' commentary". The Spectator called Bleak House "a heavy book to read through at once ... dull and wearisome as a serial"; Richard Simpson, in The Rambler, characterised Hard Times as "this dreary framework"; Fraser's Magazine thought Little Dorrit "decidedly the worst of his novels". All the same, despite these "increasing reservations amongst reviewers and the chattering classes, 'the public never deserted its favourite'". Dickens's popular reputation remained unchanged, sales continued to rise, and Household Words and later All the Year Round were highly successful.
As his career progressed, Dickens's fame and the demand for his public readings were unparalleled. In 1868 The Times wrote, "Amid all the variety of 'readings', those of Mr Charles Dickens stand alone." A Dickens biographer, Edgar Johnson, wrote in the 1950s: "It was [always] more than a reading; it was an extraordinary exhibition of acting that seized upon its auditors with a mesmeric possession." Juliet John backed the claim for Dickens "to be called the first self-made global media star of the age of mass culture." Comparing his reception at public readings to those of a contemporary pop star, The Guardian states, "People sometimes fainted at his shows. His performances even saw the rise of that modern phenomenon, the 'speculator' or ticket tout (scalpers) – the ones in New York City escaped detection by borrowing respectable-looking hats from the waiters in nearby restaurants."
"Dickens's vocal impersonations of his own characters gave this truth a theatrical form: the public reading tour. No other Victorian could match him for celebrity, earnings, and sheer vocal artistry. The Victorians craved the author's multiple voices: between 1853 and his death in 1870, Dickens performed about 470 times."
—Peter Garratt in The Guardian on Dickens's fame and the demand for his public readings
Among fellow writers, there was a range of opinions on Dickens. Poet laureate, William Wordsworth (1770–1850), thought him a "very talkative, vulgar young person", adding he had not read a line of his work, while novelist George Meredith (1828–1909), found Dickens "intellectually lacking". In 1888, Leslie Stephen commented in the Dictionary of National Biography that "if literary fame could be safely measured by popularity with the half-educated, Dickens must claim the highest position among English novelists". Anthony Trollope's Autobiography famously declared Thackeray, not Dickens, to be the greatest novelist of the age. However, both Leo Tolstoy and Fyodor Dostoyevsky were admirers. Dostoyevsky commented: "We understand Dickens in Russia, I am convinced, almost as well as the English, perhaps even with all the nuances. It may well be that we love him no less than his compatriots do. And yet how original is Dickens, and how very English!" Tolstoy referred to David Copperfield as his favourite book, and he later adopted the novel as "a model for his own autobiographical reflections". French writer Jules Verne called Dickens his favourite writer, writing his novels "stand alone, dwarfing all others by their amazing power and felicity of expression". Dutch painter Vincent van Gogh was inspired by Dickens's novels in several of his paintings, such as Vincent's Chair, and in an 1889 letter to his sister stated that reading Dickens, especially A Christmas Carol, was one of the things that was keeping him from committing suicide. Oscar Wilde generally disparaged his depiction of character, while admiring his gift for caricature. Henry James denied him a premier position, calling him "the greatest of superficial novelists": Dickens failed to endow his characters with psychological depth, and the novels, "loose baggy monsters", betrayed a "cavalier organisation". Joseph Conrad described his own childhood in bleak Dickensian terms, noting he had "an intense and unreasoning affection" for Bleak House dating back to his boyhood. The novel influenced his own gloomy portrait of London in The Secret Agent (1907). Virginia Woolf had a love-hate relationship with Dickens, finding his novels "mesmerizing" while reproving him for his sentimentalism and a commonplace style.
Around 1940–41, the attitude of the literary critics began to warm towards Dickens – led by George Orwell in Inside the Whale and Other Essays (March 1940), Edmund Wilson in The Wound and the Bow (1941) and Humphry House in Dickens and His World. However, even in 1948, F. R. Leavis, in The Great Tradition, asserted that "the adult mind doesn't as a rule find in Dickens a challenge to an unusual and sustained seriousness"; Dickens was indeed a great genius, "but the genius was that of a great entertainer", though he later changed his opinion with Dickens the Novelist (1970, with Q. D. (Queenie) Leavis): "Our purpose", they wrote, "is to enforce as unanswerably as possible the conviction that Dickens was one of the greatest of creative writers". In 1944, Soviet film director and film theorist Sergei Eisenstein wrote an essay on Dickens's influence on cinema, such as cross-cutting – where two stories run alongside each other, as seen in novels such as Oliver Twist.
In the 1950s, "a substantial reassessment and re-editing of the works began, and critics found his finest artistry and greatest depth to be in the later novels: Bleak House, Little Dorrit, and Great Expectations – and (less unanimously) in Hard Times and Our Mutual Friend". Dickens was a favourite author of Roald Dahl; the best-selling children's author would include three of Dickens's novels among those read by the title character in his 1988 novel Matilda. An avid reader of Dickens, in 2005, Paul McCartney named Nicholas Nickleby his favourite novel. On Dickens he states, "I like the world that he takes me to. I like his words; I like the language", adding, "A lot of my stuff – it's kind of Dickensian." Screenwriter Jonathan Nolan's screenplay for The Dark Knight Rises (2012) was inspired by A Tale of Two Cities, with Nolan calling the depiction of Paris in the novel "one of the most harrowing portraits of a relatable, recognisable civilisation that completely folded to pieces". On 7 February 2012, the 200th anniversary of Dickens's birth, Philip Womack wrote in The Telegraph: "Today there is no escaping Charles Dickens. Not that there has ever been much chance of that before. He has a deep, peculiar hold upon us".
Museums and festivals celebrating Dickens's life and works exist in many places with which Dickens was associated. These include the Charles Dickens Museum in London, the historic home where he wrote Oliver Twist, The Pickwick Papers and Nicholas Nickleby; and the Charles Dickens Birthplace Museum in Portsmouth, the house in which he was born. The original manuscripts of many of his novels, as well as printers' proofs, first editions, and illustrations from the collection of Dickens's friend John Forster are held at the Victoria and Albert Museum. Dickens's will stipulated that no memorial be erected in his honour; nonetheless, a life-size bronze statue of Dickens entitled Dickens and Little Nell, cast in 1890 by Francis Edwin Elwell, stands in Clark Park in the Spruce Hill neighbourhood of Philadelphia, Pennsylvania. Another life-size statue of Dickens is located at Centennial Park in Sydney, Australia. In 1960 a bas-relief sculpture of Dickens, notably featuring characters from his books, was commissioned from sculptor Estcourt J Clack to adorn the office building built on the site of his former home at 1 Devonshire Terrace, London. In 2014, a life-size statue was unveiled near his birthplace in Portsmouth on the 202nd anniversary of his birth; this was supported by his great-great-grandsons, Ian and Gerald Dickens.
A Christmas Carol is most probably his best-known story, with frequent new adaptations. It is also the most-filmed of Dickens's stories, with many versions dating from the early years of cinema. According to the historian Ronald Hutton, the current state of the observance of Christmas is largely the result of a mid-Victorian revival of the holiday spearheaded by A Christmas Carol. Dickens catalysed the emerging Christmas as a family-centred festival of generosity, in contrast to the dwindling community-based and church-centred observations, as new middle-class expectations arose. Its archetypal figures (Scrooge, Tiny Tim, the Christmas ghosts) entered into Western cultural consciousness. "Merry Christmas", a prominent phrase from the tale, was popularised following the appearance of the story. The term Scrooge became a synonym for miser, and his exclamation "Bah! Humbug!'", a dismissal of the festive spirit, likewise gained currency as an idiom. The Victorian era novelist William Makepeace Thackeray called the book "a national benefit, and to every man and woman who reads it a personal kindness".
Dickens was commemorated on the Series E £10 note issued by the Bank of England that circulated between 1992 and 2003. His portrait appeared on the reverse of the note accompanied by a scene from The Pickwick Papers. The Charles Dickens School is a high school in Broadstairs, Kent. A theme park, Dickens World, standing in part on the site of the former naval dockyard where Dickens's father once worked in the Navy Pay Office, opened in Chatham in 2007. To celebrate the 200th anniversary of the birth of Charles Dickens in 2012, the Museum of London held the UK's first major exhibition on the author in 40 years. In 2002, Dickens was number 41 in the BBC's poll of the 100 Greatest Britons. American literary critic Harold Bloom placed Dickens among the greatest Western writers of all time. In the 2003 UK survey The Big Read carried out by the BBC, five of Dickens's books were named in the Top 100.
Actors who have portrayed Dickens on screen include Anthony Hopkins, Derek Jacobi, Simon Callow, Dan Stevens and Ralph Fiennes, the latter playing the author in The Invisible Woman (2013) which depicts Dickens's secret love affair with Ellen Ternan which lasted for thirteen years until his death in 1870.
Dickens and his publications have appeared on a number of postage stamps in countries including: the United Kingdom (1970, 1993, 2011 and 2012 issued by the Royal Mail—their 2012 collection marked the bicentenary of Dickens's birth), the Soviet Union (1962), Antigua, Barbuda, Botswana, Cameroon, Dubai, Fujairah, St Lucia and Turks and Caicos Islands (1970), St Vincent (1987), Nevis (2007), Alderney, Gibraltar, Jersey and Pitcairn Islands (2012), Austria (2013), and Mozambique (2014). In 1976, a crater on the planet Mercury was named in his honour.
In November 2018 it was reported that a previously lost portrait of a 31-year-old Dickens, by Margaret Gillies, had been found in Pietermaritzburg, South Africa. Gillies was an early supporter of women's suffrage and had painted the portrait in late 1843 when Dickens, aged 31, wrote A Christmas Carol. It was exhibited, to acclaim, at the Royal Academy of Arts in 1844. The Charles Dickens Museum is reported to have paid £180,000 for the portrait.
Dickens published well over a dozen major novels and novellas, a large number of short stories, including a number of Christmas-themed stories, a handful of plays, and several non-fiction books.
Dickens's novels and novellas were initially serialised in weekly and monthly magazines, then reprinted in standard book formats. | [

After three years he returned to school, before he began his literary career as a journalist. Dickens edited a weekly journal for 20 years, wrote 15 novels, five novellas, hundreds of short stories and non-fiction articles, lectured and performed readings extensively, was an indefatigable letter writer, and campaigned vigorously for children's rights, for education, and for other social reforms.",

"text": "Dickens's literary success began with the 1836 serial publication of The Pickwick Papers, a publishing phenomenon—thanks largely to the introduction of the character Sam Weller in the fourth episode—that sparked Pickwick merchandise and spin-offs. Within a few years, Dickens had become an international literary celebrity, famous for his humour, satire and keen observation of character and society. His novels, most of them published in monthly or weekly installments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. Cliffhanger endings in his serial publications kept readers in suspense. The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her own disabilities, Dickens improved the character with positive features. His plots were carefully constructed and he often wove elements from topical events into his narratives. Masses of the illiterate poor would individually pay a halfpenny to have each new monthly episode read to them, opening up and inspiring a new class of readers.",

The most famous celebrity of his era, he undertook, in response to public demand, a series of public reading tours in the later part of his career.

When a certain number of grosses of pots had attained this pitch of perfection, I was to paste on each a printed label, and then go on again with more pots. Two or three other boys were kept at similar duty down-stairs on similar wages.

He rented rooms at Furnival's Inn and worked as a political journalist, reporting on Parliamentary debates, and he travelled across Britain to cover election campaigns for the Morning Chronicle. His journalism, in the form of sketches in periodicals, formed his first collection of pieces, published in 1836: Sketches by Boz – Boz being a family nickname he employed as a pseudonym for some years. Dickens apparently adopted it from the nickname 'Moses', which he had given to his youngest brother Augustus Dickens, after a character in Oliver Goldsmith's The Vicar of Wakefield. When pronounced by anyone with a head cold, \"Moses\" became \"Boses\" – later shortened to Boz. Dickens's own name was considered \"queer\" by a contemporary critic, who wrote in 1849: \"Mr Dickens, as if in revenge for his own queer name, does bestow still queerer ones upon his fictitious creations.\" Dickens contributed to and edited journals throughout his literary career. In January 1835, the Morning Chronicle launched an evening edition, under the editorship of the Chronicle's music critic, George Hogarth. Hogarth invited him to contribute Street Sketches and Dickens became a regular visitor to his Fulham house – excited by Hogarth's friendship with Walter Scott (whom Dickens greatly admired) and enjoying the company of Hogarth's three daughters: Georgina, Mary and 19-year-old Catherine.",

All these became his friends and collaborators, with the exception of Disraeli, and he met his first publisher, John Macrone, at the house. The success of Sketches by Boz led to a proposal from publishers Chapman and Hall for Dickens to supply text to match Robert Seymour's engraved illustrations in a monthly letterpress. Seymour committed suicide after the second instalment and Dickens, who wanted to write a connected series of sketches, hired \"Phiz\" to provide the engravings (which were reduced from four to two per instalment) for the story. The resulting story became The Pickwick Papers and, although the first few episodes were not successful, the introduction of the Cockney character Sam Weller in the fourth episode (the first to be illustrated by Phiz) marked a sharp climb in its popularity. The final instalment sold 40,000 copies. On the impact of the character, The Paris Review stated, \"arguably the most historic bump in English publishing is the Sam Weller Bump.\" A publishing phenomenon, John Sutherland called The Pickwick Papers \"[t]he most important single novel of the Victorian era\".

These attacks would later be expanded on his 1856 play The Frozen Deep, which satirizes Rae and the Inuit. 20th century archaeology work in King William Island later confirmed that the members of the Franklin expedition resorted to cannibalism.",

With the exception of Lord John Russell, who was the only leading politician in whom Dickens had any faith and to whom he later dedicated A Tale of Two Cities, Dickens believed that the political aristocracy and their incompetence were the death of England. When he and Layard were accused of fomenting class conflict, Dickens replied that the classes were already in opposition and the fault was with the aristocratic class. Dickens used his pulpit in Household Words to champion the Reform Association. He also commented on foreign affairs, declaring his support for Giuseppe Garibaldi and Giuseppe Mazzini, helping raise funds for their campaigns and stating that \"a united Italy would be of vast importance to the peace of the world, and would be a rock in Louis Napoleon's way,\" and that \"I feel for Italy almost as if I were an Italian born.\" Dickens also published dozens of writings in Household Words supporting vaccination, including multiple laudations for vaccine pioneer Edward Jenner.",

According to Ackroyd, other than these, perhaps the most important literary influence on him was derived from the fables of The Arabian Nights. Satire and irony are central to the picaresque novel. Comedy is also an aspect of the British picaresque novel tradition of Laurence Sterne, Henry Fielding and Tobias Smollett. Fielding's Tom Jones was a major influence on the 19th-century novelist including Dickens, who read it in his youth and named a son Henry Fielding Dickens after him. Influenced by Gothic fiction—a literary genre that began with The Castle of Otranto (1764) by Horace Walpole—Dickens incorporated Gothic imagery, settings and plot devices in his works. Victorian gothic moved from castles and abbeys into contemporary urban environments: in particular London, such as Dickens's Oliver Twist and Bleak House. The jilted bride Miss Havisham from Great Expectations is one of Dickens's best-known gothic creations; living in a ruined mansion, her bridal gown effectively doubles as her funeral shroud.",

Regarding Shakespeare as \"the great master\" whose plays \"were an unspeakable source of delight\", Dickens's lifelong affinity with the playwright included seeing theatrical productions of his plays in London and putting on amateur dramatics with friends in his early years. In 1838, Dickens travelled to Stratford-upon-Avon and visited the house in which Shakespeare was born, leaving his autograph in the visitors' book. Dickens would draw on this experience in his next work, Nicholas Nickleby (1838–39), expressing the strength of feeling experienced by visitors to Shakespeare's birthplace: the character Mrs Wititterly states, \"I don't know how it is, but after you've seen the place and written your name in the little book, somehow or other you seem to be inspired; it kindles up quite a fire within one.\"",

An early reviewer compared him to Hogarth for his keen practical sense of the ludicrous side of life, though his acclaimed mastery of varieties of class idiom may in fact mirror the conventions of contemporary popular theatre. Dickens worked intensively on developing arresting names for his characters that would reverberate with associations for his readers and assist the development of motifs in the storyline, giving what one critic calls an \"allegorical impetus\" to the novels' meanings. To cite one of numerous examples, the name Mr Murdstone in David Copperfield conjures up twin allusions to murder and stony coldness. His literary style is also a mixture of fantasy and realism. His satires of British aristocratic snobbery – he calls one character the \"Noble Refrigerator\" – are often popular. Comparing orphans to stocks and shares, people to tug boats or dinner-party guests to furniture are just some of Dickens's acclaimed flights of fancy.",

Through his journalism he campaigned on specific issues – such as sanitation and the workhouse – but his fiction probably demonstrated its greatest prowess in changing public opinion in regard to class inequalities. He often depicted the exploitation and oppression of the poor and condemned the public officials and institutions that not only allowed such abuses to exist, but flourished as a result. His most strident indictment of this condition is in Hard Times (1854), Dickens's only novel-length treatment of the industrial working class. In this work, he uses vitriol and satire to illustrate how this marginalised social stratum was termed \"Hands\" by the factory owners; that is, not really \"people\" but rather only appendages of the machines they operated. His writings inspired others, in particular journalists and political figures, to address such problems of class oppression. For example, the prison scenes in The Pickwick Papers are claimed to have been influential in having the Fleet Prison shut down. Karl Marx asserted that Dickens \"issued to the world more political and social truths than have been uttered by all the professional politicians, publicists and moralists put together\". George Bernard Shaw even remarked that Great Expectations was more seditious than Marx's Das Kapital. The exceptional popularity of Dickens's novels, even those with socially oppositional themes (Bleak House, 1853; Little Dorrit, 1857; Our Mutual Friend, 1865), not only underscored his ability to create compelling storylines and unforgettable characters, but also ensured that the Victorian public confronted issues of social justice that had commonly been ignored.",

Dickens's popular reputation remained unchanged, sales continued to rise, and Household Words and later All the Year Round were highly successful.",

"text": "Among fellow writers, there was a range of opinions on Dickens. Poet laureate, William Wordsworth (1770–1850), thought him a \"very talkative, vulgar young person\", adding he had not read a line of his work, while novelist George Meredith (1828–1909), found Dickens \"intellectually lacking\". In 1888, Leslie Stephen commented in the Dictionary of National Biography that \"if literary fame could be safely measured by popularity with the half-educated, Dickens must claim the highest position among English novelists\". Anthony Trollope's Autobiography famously declared Thackeray, not Dickens, to be the greatest novelist of the age. However, both Leo Tolstoy and Fyodor Dostoyevsky were admirers. Dostoyevsky commented: \"We understand Dickens in Russia, I am convinced, almost as well as the English, perhaps even with all the nuances. It may well be that we love him no less than his compatriots do. And yet how original is Dickens, and how very English!\" Tolstoy referred to David Copperfield as his favourite book, and he later adopted the novel as \"a model for his own autobiographical reflections\". French writer Jules Verne called Dickens his favourite writer, writing his novels \"stand alone, dwarfing all others by their amazing power and felicity of expression\". Dutch painter Vincent van Gogh was inspired by Dickens's novels in several of his paintings, such as Vincent's Chair, and in an 1889 letter to his sister stated that reading Dickens, especially A Christmas Carol, was one of the things that was keeping him from committing suicide. Oscar Wilde generally disparaged his depiction of character, while admiring his gift for caricature. Henry James denied him a premier position, calling him \"the greatest of superficial novelists\": Dickens failed to endow his characters with psychological depth, and the novels, \"loose baggy monsters\", betrayed a \"cavalier organisation\". Joseph Conrad described his own childhood in bleak Dickensian terms, noting he had \"an intense and unreasoning affection\" for Bleak House dating back to his boyhood. The novel influenced his own gloomy portrait of London in The Secret Agent (1907). Virginia Woolf had a love-hate relationship with Dickens, finding his novels \"mesmerizing\" while reproving him for his sentimentalism and a commonplace style.",

However, even in 1948, F. R. Leavis, in The Great Tradition, asserted that \"the adult mind doesn't as a rule find in Dickens a challenge to an unusual and sustained seriousness\"; Dickens was indeed a great genius, \"but the genius was that of a great entertainer\", though he later changed his opinion with Dickens the Novelist (1970, with Q. D. (Queenie) Leavis): \"Our purpose\", they wrote, \"is to enforce as unanswerably as possible the conviction that Dickens was one of the greatest of creative writers\".

Dickens was a favourite author of Roald Dahl; the best-selling children's author would include three of Dickens's novels among those read by the title character in his 1988 novel Matilda. An avid reader of Dickens, in 2005, Paul McCartney named Nicholas Nickleby his favourite novel. On Dickens he states, \"I like the world that he takes me to.

It is also the most-filmed of Dickens's stories, with many versions dating from the early years of cinema. According to the historian Ronald Hutton, the current state of the observance of Christmas is largely the result of a mid-Victorian revival of the holiday spearheaded by A Christmas Carol. Dickens catalysed the emerging Christmas as a family-centred festival of generosity, in contrast to the dwindling community-based and church-centred observations, as new middle-class expectations arose. Its archetypal figures (Scrooge, Tiny Tim, the Christmas ghosts) entered into Western cultural consciousness. \"Merry Christmas\", a prominent phrase from the tale, was popularised following the appearance of the story. The term Scrooge became a synonym for miser, and his exclamation \"Bah! Humbug!'\", a dismissal of the festive spirit, likewise gained currency as an idiom. The Victorian era novelist William Makepeace Thackeray called the book \"a national benefit, and to every man and woman who reads it a personal kindness\".",

] | Charles John Huffam Dickens was an English novelist and social critic who created some of the world's best-known fictional characters, and is regarded by many as the greatest novelist of the Victorian era. His works enjoyed unprecedented popularity during his lifetime and, by the 20th century, critics and scholars had recognised him as a literary genius. His novels and short stories are widely read today. Born in Portsmouth, Dickens left school at the age of 12 to work in a boot-blacking factory when his father John was incarcerated in a debtors' prison. After three years he returned to school, before he began his literary career as a journalist. Dickens edited a weekly journal for 20 years, wrote 15 novels, five novellas, hundreds of short stories and non-fiction articles, lectured and performed readings extensively, was an indefatigable letter writer, and campaigned vigorously for children's rights, for education, and for other social reforms. Dickens's literary success began with the 1836 serial publication of The Pickwick Papers, a publishing phenomenon—thanks largely to the introduction of the character Sam Weller in the fourth episode—that sparked Pickwick merchandise and spin-offs. Within a few years, Dickens had become an international literary celebrity, famous for his humour, satire and keen observation of character and society. His novels, most of them published in monthly or weekly installments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. Cliffhanger endings in his serial publications kept readers in suspense. The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her own disabilities, Dickens improved the character with positive features. His plots were carefully constructed and he often wove elements from topical events into his narratives. Masses of the illiterate poor would individually pay a halfpenny to have each new monthly episode read to them, opening up and inspiring a new class of readers. His 1843 novella A Christmas Carol remains especially popular and continues to inspire adaptations in every creative medium. Oliver Twist and Great Expectations are also frequently adapted and, like many of his novels, evoke images of early Victorian London. His 1859 novel A Tale of Two Cities is his best-known work of historical fiction. The most famous celebrity of his era, he undertook, in response to public demand, a series of public reading tours in the later part of his career. The term Dickensian is used to describe something that is reminiscent of Dickens and his writings, such as poor social or working conditions, or comically repulsive characters. | 2001-10-23T16:18:01Z | 2024-01-01T01:11:15Z | [

5,898 | Carabiner | A carabiner or karabiner (/ˌkærəˈbiːnər/), often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word comes from the German Karabiner, short for Karabinerhaken, meaning "carbine rifle hook" used by a carbine rifleman, or carabinier, to attach his carbine to a belt or bandolier.
Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot-air ballooning, rope rescue, construction, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue.
Often referred to as carabiner-style or as mini-carabiners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Most are stamped with a "not for climbing" or similar warning due to a common lack of load-testing and safety standards in manufacturing.
While any metal link with a spring-loaded gate is technically a carabiner, the strict usage among the climbing community specifically refers only to devices manufactured and tested for load-bearing in safety-critical systems like rock and mountain climbing, typically rated to 20 kN or more.
Carabiners on hot-air balloons are used to connect the envelope to the basket and are rated at 2.5, 3, or 4 tonnes.
Load-bearing screw-gate carabiners are used to connect the diver's umbilical to the surface supplied diver's harness. They are usually rated for a safe working load of 5 kN or more (equivalent to a weight in excess of approximately 500 kg).
Carabiners come in four characteristic shapes:
Carabiners fall into three broad locking categories: non-locking, manual locking, and auto locking.
Non-locking carabiners (or snap-links) have a sprung swinging gate that accepts a rope, webbing sling, or other hardware. Rock climbers frequently connect two non-locking carabiners with a short length of webbing to create a quickdraw (an extender).
Two gate types are common:
Both solid and wire gate carabiners can be either "straight gate" or "bent gate". Bent-gate carabiners are easier to clip a rope into using only one hand, and so are often used for the rope-end carabiner of quickdraws and alpine draws used for lead climbing.
Locking carabiners have the same general shape as non-locking carabiners, but have an additional mechanism securing the gate to prevent unintentional opening during use. These mechanisms may be either threaded sleeves ("screw-lock"), spring-loaded sleeves ("twist-lock"), magnetic levers ("Magnetron"), other spring loaded unlocking levers or opposing double spring loaded gates ("twin-gate").
American National Standards Institute/American Society of Safety Engineers standard ANSI Z359.1-2007 Safety Requirement for Personal Fall Arrest Systems, Subsystems and Components, section 3.2.1.4 (for snap hooks and carabiners) is a voluntary consensus standard. This standard requires that all connectors/ carabiners support a minimum breaking strength (MBS) of 5,000 lbf (22 kN) and feature an auto-locking gate mechanism which supports a minimum breaking strength (MBS) of 3,600 lbf (16 kN). | [

5,899 | Continuity (fiction) | In fiction, continuity is the consistency of the characteristics of people, plot, objects, and places seen by the audience over some period of time. It is relevant to many genres and forms of storytelling, especially if it is long-running.
Continuity is particularly a concern in the process of film and television production due to the difficulty in rectifying errors after filming ends. Continuity can also apply to other art forms, such as novels, comics, and video games, though usually on a smaller scale; it also applies to fiction used by persons, corporations, and governments in the public eye.
Most film and TV productions have a script supervisor on hand whose job is to pay attention to and attempt to maintain continuity across the chaotic and typically non-linear production schedule. It is an inconspicuous job because if done well, none may ever notice. The script supervisor gathers numerous paperwork, photographs, and other documentation which note a large quantity of detail for maintaining the continuity of the production; Some of the gathered documents can be sometimes assembled into the story bible. The gathered information and photographs usually regard factors both within the scene and the technical details of the production, including meticulous records of camera positioning and equipment settings. Film-based Polaroid cameras were once standard but have since been replaced by digital cameras; all of this is, ideally, all related shots can match, due to filming being split up over months in different sets and locations.
In comic books, continuity has also come to mean a set of contiguous events, sometimes said to be "set in the same universe."
Many continuity errors are subtle, such as minor changes between shots (like the level of drink in a glass or the length of a cigarette); these minor errors often remain due to relative indifference to the final cut. While minor errors are often unnoticed by the average viewer, other errors may be more noticeable, such as sudden drastic changes in the appearance of a character. Productions will aim to prevent such errors in continuity because they can affect the audience's suspension of disbelief.
In cinema, special attention must be paid to continuity because scenes are rarely shot in the order in which they appear in the final film. The shooting schedule is often dictated by location permit issues and other logistics. For example, a character may return to Times Square in New York City several times throughout a movie, but as it is extraordinarily expensive to close off Times Square, those scenes will likely be filmed all at once to reduce permit costs. Weather, the ambiance of natural light, cast and crew availability, or any number of other circumstances can also influence a shooting schedule.
Film production companies use various techniques to prevent continuity errors. The first would be to film all the shots for a particular scene together and all shots of consecutive scenes together (if the scenes take place together, with no break between them in the film's timeline). This allows actors to remain in costume, in character, and in the same location (and with the same weather, if shooting on location).
The second major technique is for costume designers, production designers, prop masters, and make-up artists to take instant photographs of actors and sets at the beginning and end of each day's shooting (once made possible by Polaroid cameras, now done with digital cameras and cell phones as well). This allows the various workers to check each day's clothing, set, props, and make-up against a previous day's.
The third is to avoid shooting on location entirely but instead film everything on a studio set. This allows weather and lighting to be controlled (as the shooting is indoors), and for all clothing and sets to be stored in one place to be hauled out the next day from a secure location.
Editing errors can occur when a character in a scene references a scene or incident that has not occurred yet, or of which they should not yet be aware.
An example of an editing error can be seen in the film It's a Mad, Mad, Mad, Mad World (1963), where a scene of people climbing a slope at the start is seen from below and then replayed from above.
Visual errors are instant discontinuities occurring in visual media such as film and television. Items of clothing change colors, shadows get longer or shorter, items within a scene change place or disappear, etc.
One of the earliest examples of a visual error appears in Charlie Chaplin's 1914 movie The Property Man. Here, in a supposedly smooth step from one room to another, the Tramp loses his hat in one room, but it is instantly back on his head as he enters the next room. Rather "loose" plots and a lack of continuity editing made most early films rife with such errors.
Another example occurs in the 1998 film Waking Ned, when two of the film's characters, Jackie and Michael, are walking through a storm towards Ned's house. The umbrella they are under is black during their conversation as they walk towards the house (filmed from slightly above and to the front). However, after cutting to a lower shot (filmed from behind Jackie), Michael walks onscreen from the right holding an umbrella that is not black but beige, with a brown band at the rim.
Another glaring example of poor continuity occurs in the Disney film Pete’s Dragon (filmed in 1976). During the song "Brazzle Dazzle Day" when Lampie (Mickey Rooney), Pete (Sean Marshall), and Nora (Helen Reddy) climb the stairs to the top of the lighthouse, Pete's shirt beneath his overalls is orange. But after descending to the bottom again and coming out of the lighthouse door, his shirt is now grey.
A plot error, or a plot hole as it is commonly known, reflects a failure in the consistency of the created fictional world. A character might state he was an only child, yet later mention a sibling. In the TV show Cheers, Frasier Crane's wife Lilith mentions Frasier's parents are both dead, and, in another episode, Frasier himself claims his father to have been a scientist. When the character was spun off into Frasier, his father, a retired policeman named Martin, became a central character. Eventually, in an episode featuring Cheers star Ted Danson, the inconsistency was given the retroactive explanation that Frasier was embarrassed about his father's lowbrow attitudes and thus claimed his death. This is a frequent occurrence in sitcoms, where networks may agree to continue a show, but only if a certain character is emphasized, leading other minor characters to be written out of the show with no further mention of the character's existence, while the emphasized character (usually a breakout character, as in the case of Frasier Crane) develops a more complete back story that ignores previous, more simplified backstories.
A Homeric nod (sometimes heard as 'Even Homer nods') is a term for a continuity error that has its origins in Homeric epic. The proverbial phrase for it was coined by the Roman poet Horace in his Ars Poetica: "et idem indignor quandoque bonus dormitat Homerus" ("and yet I also become annoyed whenever the great Homer nods off").
There are numerous continuity errors in Homer that can be described as "nods", as for example:
In modern Homeric scholarship, many of Homer's "nods" are explicable as the consequences of the poem being retold and improvised by generations of oral poets. In the second case cited above, it is likely that two different versions are being conflated: one version with an embassy of three people, another with just two people. Alexander Pope was inclined to give Homeric nods the benefit of the doubt, saying in his Essay on Criticism that "Those oft are Stratagems which Errors seem, Nor is it Homer Nods, but We that Dream."
The practice of accelerating the age of a television character (usually a child or teenager) in conflict with the timeline of a series and/or the real-world progression of time is popularly known as Soap Opera Rapid Aging Syndrome, or SORAS. Children unseen on screen for a time might reappear portrayed by an actor several years older than the original. Usually coinciding with a recast, this rapid aging is typically done to open up the character to a wider range of storylines, and to attract younger viewers. A recent example of this occurring is in the BBC's Merlin series, in which Mordred is initially played by a young child in Season 4, yet suddenly grows up into his late teens in time for the start of Season 5, with the rest of the characters aging by only three years.
The reverse can also happen. On the television program Lost, the character of 10-year-old Walt Lloyd was played by 12-year-old actor Malcolm David Kelley. The first few seasons took place over the course of just a few months, but by that point, Lloyd looked much older than 10. In his remaining few appearances, special effects were used to make him look younger, or the scene took place years later.
Sometimes a work of fiction may deliberately employ continuity errors, usually for comedy. For example, in the Marx Brothers' classic film Duck Soup, at the climax of the film, the camera shows a shot of Groucho Marx speaking a line, followed by a cutaway shot of something else happening, followed by another shot of Groucho. Each time, Groucho's hat changes, usually to something more outrageous than before (a Napoleonic hat, a Prussian hat, etc.).
When continuity mistakes have been made, explanations are often proposed by either writers or fans to smooth over discrepancies. Fans sometimes make up explanations for such errors that may or may not be integrated into canon; this has come to be colloquially known as fanwanking (a term originally coined by the author Craig Hinton to describe excessive use of continuity). Often when fans do not agree with one of the events in a story (such as the death of a favorite character), they will choose to ignore the event in question so that their enjoyment of the franchise is not diminished. When the holder of the intellectual property discards all existing continuity and starts from scratch, it is known as rebooting. Fans call a less extreme literary technique that erases one episode the reset button. See also fanon.
A conflict with previously-established facts is sometimes deliberate; this is a retcon, as it is a retroactive change in continuity. Retcons sometimes clarify ambiguities or correct perceived errors. This is not to be confused with the continuance of a reality (continuality).
Television programs like 24, in which actors have to appear as if it is the same day for 24 consecutive episodes, have raised public recognition of continuity. However, traditional films have frequently had much of the same sort of issues to deal with; film shoots may last several months, and as scenes are frequently shot out of story sequence, footage shot weeks apart may be edited together as part of the same day's action in the completed film. In some ways, 24 presents a simpler situation, as costumes and hairstyles generally should not change very frequently; in many feature films, a range of different hairstyles and costumes must be created, changed, and then recreated exactly, as various scenes are shot.
Some fiction ignores continuity to allow characters to slow or stop the aging process, despite real-world markers like major social or technological changes. In comics this is sometimes referred to as a "floating timeline", where the fiction takes place in a "continuous present". Roz Kaveney suggests that comic books use this technique to satisfy "the commercial need to keep certain characters going forever". This is also due to the fact that the authors have no need to accommodate the aging of their characters, which is also typical of most animated television shows. Kevin Wanner compares the use of a sliding timescale in comics to the way ageless figures in myths are depicted interacting with the contemporary world of the storyteller. When certain stories in comics, especially origin stories, are rewritten, they often retain key events but are updated to a contemporary time, such as with the comic book character Tony Stark, who invents his Iron Man armor in a different war depending on when the story is told. | [

When the character was spun off into Frasier, his father, a retired policeman named Martin, became a central character. Eventually, in an episode featuring Cheers star Ted Danson, the inconsistency was given the retroactive explanation that Frasier was embarrassed about his father's lowbrow attitudes and thus claimed his death. This is a frequent occurrence in sitcoms, where networks may agree to continue a show, but only if a certain character is emphasized, leading other minor characters to be written out of the show with no further mention of the character's existence, while the emphasized character (usually a breakout character, as in the case of Frasier Crane) develops a more complete back story that ignores previous, more simplified backstories.",

5,902 | Capital punishment | Capital punishment, also known as the death penalty and formerly called judicial homicide, is the state-sanctioned practice of killing a person as a punishment for a crime, usually following an authorised, rule-governed process to conclude that the person is responsible for violating norms that warrant said punishment. The sentence ordering that an offender be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being "on death row". Etymologically, the term capital (lit. "of the head", derived via the Latin capitalis from caput, "head") refers to execution by beheading, but executions are carried out by many methods, including hanging, shooting, lethal injection, stoning, electrocution, and gassing.
Crimes that are punishable by death are known as capital crimes, capital offences, or capital felonies, and vary depending on the jurisdiction, but commonly include serious crimes against a person, such as assassination, mass murder, child murder, aggravated rape, terrorism, aircraft hijacking, war crimes, crimes against humanity, and genocide, along with crimes against the state such as attempting to overthrow government, treason, espionage, sedition, and piracy. Also, in some cases, acts of recidivism, aggravated robbery, and kidnapping, in addition to drug trafficking, drug dealing, and drug possession, are capital crimes or enhancements. However, states have also imposed punitive executions, for an expansive range of conduct, for political or religious beliefs and practices, for a status beyond one's control, or without employing any significant due process procedures. Judicial murder is the intentional and premeditated killing of an innocent person by means of capital punishment. For example, the executions following the show trials in the Soviet Union during the Great Purge of 1936–1938 were an instrument of political repression.
As of late 2022, 53 countries retain capital punishment, 111 countries have completely abolished it de jure for all crimes, seven have abolished it for ordinary crimes (while maintaining it for special circumstances such as war crimes), and 24 are abolitionist in practice. Although the majority of nations have abolished capital punishment, over 60% of the world's population live in countries where the death penalty is retained, such as China, India, the United States, Singapore, Indonesia, Pakistan, Bangladesh, Nigeria, Egypt, Saudi Arabia, Iran, Japan, and Taiwan.
Capital punishment is controversial, with many people, organisations, and religious groups holding differing views on whether it is ethically permissible. Amnesty International declares that the death penalty breaches human rights, specifically "the right to life and the right to live free from torture or cruel, inhuman or degrading treatment or punishment." These rights are protected under the Universal Declaration of Human Rights, adopted by the United Nations in 1948. In the European Union (EU), Article 2 of the Charter of Fundamental Rights of the European Union prohibits the use of capital punishment. The Council of Europe, which has 46 member states, has sought to abolish the use of the death penalty by its members absolutely, through Protocol 13 of the European Convention on Human Rights. However, this only affects those member states which have signed and ratified it, and they do not include Armenia and Azerbaijan. The United Nations General Assembly has adopted, throughout the years from 2007 to 2020, eight non-binding resolutions calling for a global moratorium on executions, with a view to eventual abolition.
Execution of criminals and dissidents has been used by nearly all societies since the beginning of civilisations on Earth. Until the nineteenth century, without developed prison systems, there was frequently no workable alternative to ensure deterrence and incapacitation of criminals. In pre-modern times the executions themselves often involved torture with painful methods, such as the breaking wheel, keelhauling, sawing, hanging, drawing and quartering, burning at the stake, crucifixion, flaying, slow slicing, boiling alive, impalement, mazzatello, blowing from a gun, schwedentrunk, and scaphism. Other methods which appear only in legend include the blood eagle and brazen bull.
The use of formal execution extends to the beginning of recorded history. Most historical records and various primitive tribal practices indicate that the death penalty was a part of their justice system. Communal punishments for wrongdoing generally included blood money compensation by the wrongdoer, corporal punishment, shunning, banishment and execution. In tribal societies, compensation and shunning were often considered enough as a form of justice. The response to crimes committed by neighbouring tribes, clans or communities included a formal apology, compensation, blood feuds, and tribal warfare.
A blood feud or vendetta occurs when arbitration between families or tribes fails, or an arbitration system is non-existent. This form of justice was common before the emergence of an arbitration system based on state or organized religion. It may result from crime, land disputes or a code of honour. "Acts of retaliation underscore the ability of the social collective to defend itself and demonstrate to enemies (as well as potential allies) that injury to property, rights, or the person will not go unpunished."
In most countries that practice capital punishment, it is now reserved for murder, terrorism, war crimes, espionage, treason, or as part of military justice. In some countries, sexual crimes, such as rape, fornication, adultery, incest, sodomy, and bestiality carry the death penalty, as do religious crimes such as Hudud, Zina, and Qisas crimes, such as apostasy (formal renunciation of the state religion), blasphemy, moharebeh, hirabah, Fasad, Mofsed-e-filarz and witchcraft. In many countries that use the death penalty, drug trafficking and often drug possession is also a capital offence. In China, human trafficking and serious cases of corruption and financial crimes are punished by the death penalty. In militaries around the world, courts-martial have imposed death sentences for offences such as cowardice, desertion, insubordination, and mutiny.
Elaborations of tribal arbitration of feuds included peace settlements often done in a religious context and compensation system. Compensation was based on the principle of substitution which might include material (for example, cattle, slaves, land) compensation, exchange of brides or grooms, or payment of the blood debt. Settlement rules could allow for animal blood to replace human blood, or transfers of property or blood money or in some case an offer of a person for execution. The person offered for execution did not have to be an original perpetrator of the crime because the social system was based on tribes and clans, not individuals. Blood feuds could be regulated at meetings, such as the Norsemen things. Systems deriving from blood feuds may survive alongside more advanced legal systems or be given recognition by courts (for example, trial by combat or blood money). One of the more modern refinements of the blood feud is the duel.
In certain parts of the world, nations in the form of ancient republics, monarchies or tribal oligarchies emerged. These nations were often united by common linguistic, religious or family ties. Moreover, expansion of these nations often occurred by conquest of neighbouring tribes or nations. Consequently, various classes of royalty, nobility, various commoners and slaves emerged. Accordingly, the systems of tribal arbitration were submerged into a more unified system of justice which formalized the relation between the different "social classes" rather than "tribes". The earliest and most famous example is Code of Hammurabi which set the different punishment and compensation, according to the different class or group of victims and perpetrators. The Torah/Old Testament lays down the death penalty for murder, kidnapping, practicing magic, violation of the Sabbath, blasphemy, and a wide range of sexual crimes, although evidence suggests that actual executions were exceedingly rare, if they occurred at all.
A further example comes from Ancient Greece, where the Athenian legal system replacing customary oral law was first written down by Draco in about 621 BC: the death penalty was applied for a particularly wide range of crimes, though Solon later repealed Draco's code and published new laws, retaining capital punishment only for intentional homicide, and only with victim's family permission. The word draconian derives from Draco's laws. The Romans also used the death penalty for a wide range of offences.
Protagoras (whose thought is reported by Plato) criticised the principle of revenge, because once the damage is done it cannot be cancelled by any action. So, if the death penalty is to be imposed by society, it is only to protect the latter against the criminal or for a dissuasive purpose. "The only right that Protagoras knows is therefore human right, which, established and sanctioned by a sovereign collectivity, identifies itself with positive or the law in force of the city. In fact, it finds its guarantee in the death penalty which threatens all those who do not respect it."
Plato saw the death penalty as a means of purification, because crimes are a "defilement". Thus, in the Laws, he considered necessary the execution of the animal or the destruction of the object which caused the death of a man by accident. For the murderers, he considered that the act of homicide is not natural and is not fully consented by the criminal. Homicide is thus a disease of the soul, which must be reeducated as much as possible, and, as a last resort, sentence to death if no rehabilitation is possible.
According to Aristotle, for whom free will is proper to man, a person is responsible for their actions. If there was a crime, a judge must define the penalty allowing the crime to be annulled by compensating it. This is how pecuniary compensation appeared for criminals the least recalcitrant and whose rehabilitation is deemed possible. However, for others, he argued, the death penalty is necessary.
This philosophy aims on the one hand to protect society and on the other hand to compensate to cancel the consequences of the crime committed. It inspired Western criminal law until the 17th century, a time when the first reflections on the abolition of the death penalty appeared.
The Twelve Tables, which was the foundational law of Rome, prescribes the death penalty for a variety of crimes including libel, arson and theft. During the Late Republic, there was consensus among the public and legislators to reduce the incidence of capital punishment. This opinion led to voluntary exile being prescribed in place of the death penalty, whereby a convict could either choose to leave in exile or face execution.
A historic debate, followed by a vote, took place in the Roman Senate to decide the fate of Catiline's allies when he attempted to seize power in December, 63 BC. Cicero, then Roman consul, argued in support of the killing of conspirators without judgment by decision of the Senate (Senatus consultum ultimum) and was supported by the majority of senators; among the minority voices opposed to the execution, the most notable was Julius Caesar. The custom was different for foreigners, as they were considered inferior to Roman citizens, and especially for slaves, who were transferrable property.
An excruciating slow death by crucifixion was widely practiced by the Romans. Intended to be a punishment, a humiliation, and a deterrent, the condemned could take up to a few days to die. Corpses of the crucified were typically left on the crosses to decompose and to be eaten by animals.
Although many are executed in the People's Republic of China each year in the present day, there was a time in the Tang dynasty (618–907) when the death penalty was abolished. This was in the year 747, enacted by Emperor Xuanzong of Tang (r. 712–756). When abolishing the death penalty, Xuanzong ordered his officials to refer to the nearest regulation by analogy when sentencing those found guilty of crimes for which the prescribed punishment was execution. Thus, depending on the severity of the crime a punishment of severe scourging with the thick rod or of exile to the remote Lingnan region might take the place of capital punishment. However, the death penalty was restored only 12 years later in 759 in response to the An Lushan Rebellion. At this time in the Tang dynasty only the emperor had the authority to sentence criminals to execution. Under Xuanzong capital punishment was relatively infrequent, with only 24 executions in the year 730 and 58 executions in the year 736.
The two most common forms of execution in the Tang dynasty were strangulation and decapitation, which were the prescribed methods of execution for 144 and 89 offences respectively. Strangulation was the prescribed sentence for lodging an accusation against one's parents or grandparents with a magistrate, scheming to kidnap a person and sell them into slavery and opening a coffin while desecrating a tomb. Decapitation was the method of execution prescribed for more serious crimes such as treason and sedition. Despite the great discomfort involved, most of the Tang Chinese preferred strangulation to decapitation, as a result of the traditional Tang Chinese belief that the body is a gift from the parents and that it is, therefore, disrespectful to one's ancestors to die without returning one's body to the grave intact.
Some further forms of capital punishment were practiced in the Tang dynasty, of which the first two that follow at least were extralegal. The first of these was scourging to death with the thick rod which was common throughout the Tang dynasty especially in cases of gross corruption. The second was truncation, in which the convicted person was cut in two at the waist with a fodder knife and then left to bleed to death. A further form of execution called Ling Chi (slow slicing), or death by/of a thousand cuts, was used from the close of the Tang dynasty (around 900) to its abolition in 1905.
When a minister of the fifth grade or above received a death sentence the emperor might grant him a special dispensation allowing him to commit suicide in lieu of execution. Even when this privilege was not granted, the law required that the condemned minister be provided with food and ale by his keepers and transported to the execution ground in a cart rather than having to walk there.
Nearly all executions under the Tang dynasty took place in public as a warning to the population. The heads of the executed were displayed on poles or spears. When local authorities decapitated a convicted criminal, the head was boxed and sent to the capital as proof of identity and that the execution had taken place.
In medieval and early modern Europe, before the development of modern prison systems, the death penalty was also used as a generalised form of punishment for even minor offences.
In early modern Europe, a mass panic regarding witchcraft swept across Europe and later the European colonies in North America. During this period, there were widespread claims that malevolent Satanic witches were operating as an organised threat to Christendom. As a result, tens of thousands of women were prosecuted for witchcraft and executed through the witch trials of the early modern period (between the 15th and 18th centuries).
The death penalty also targeted sexual offences such as sodomy. In the early history of Islam (7th–11th centuries), there is a number of "purported (but mutually inconsistent) reports" (athar) regarding the punishments of sodomy ordered by some of the early caliphs. Abu Bakr, the first caliph of the Rashidun Caliphate, apparently recommended toppling a wall on the culprit, or else burning him alive, while Ali ibn Abi Talib is said to have ordered death by stoning for one sodomite and had another thrown head-first from the top of the highest building in the town; according to Ibn Abbas, the latter punishment must be followed by stoning. Other medieval Muslim leaders, such as the Abbasid caliphs in Baghdad (most notably al-Mu'tadid), were often cruel in their punishments. In early modern England, the Buggery Act 1533 stipulated hanging as punishment for "buggery". James Pratt and John Smith were the last two Englishmen to be executed for sodomy in 1835. In 1636 the laws of Puritan governed Plymouth Colony included a sentence of death for sodomy and buggery. The Massachusetts Bay Colony followed in 1641. Throughout the 19th century, U.S. states repealed death sentences from their sodomy laws, with South Carolina being the last to do so in 1873.
Historians recognise that during the Early Middle Ages, the Christian populations living in the lands invaded by the Arab Muslim armies between the 7th and 10th centuries suffered religious discrimination, religious persecution, religious violence, and martyrdom multiple times at the hands of Arab Muslim officials and rulers. As People of the Book, Christians under Muslim rule were subjected to dhimmi status (along with Jews, Samaritans, Gnostics, Mandeans, and Zoroastrians), which was inferior to the status of Muslims. Christians and other religious minorities thus faced religious discrimination and religious persecution in that they were banned from proselytising (for Christians, it was forbidden to evangelise or spread Christianity) in the lands invaded by the Arab Muslims on pain of death, they were banned from bearing arms, undertaking certain professions, and were obligated to dress differently in order to distinguish themselves from Arabs. Under sharia, Non-Muslims were obligated to pay jizya and kharaj taxes, together with periodic heavy ransom levied upon Christian communities by Muslim rulers in order to fund military campaigns, all of which contributed a significant proportion of income to the Islamic states while conversely reducing many Christians to poverty, and these financial and social hardships forced many Christians to convert to Islam. Christians unable to pay these taxes were forced to surrender their children to the Muslim rulers as payment who would sell them as slaves to Muslim households where they were forced to convert to Islam. Many Christian martyrs were executed under the Islamic death penalty for defending their Christian faith through dramatic acts of resistance such as refusing to convert to Islam, repudiation of the Islamic religion and subsequent reconversion to Christianity, and blasphemy towards Muslim beliefs.
Despite the wide use of the death penalty, calls for reform were not unknown. The 12th-century Jewish legal scholar Moses Maimonides wrote: "It is better and more satisfactory to acquit a thousand guilty persons than to put a single innocent man to death." He argued that executing an accused criminal on anything less than absolute certainty would lead to a slippery slope of decreasing burdens of proof, until we would be convicting merely "according to the judge's caprice". Maimonides's concern was maintaining popular respect for law, and he saw errors of commission as much more threatening than errors of omission.
While during the Middle Ages the expiatory aspect of the death penalty was taken into account, this is no longer the case under the Lumières. These define the place of man within society no longer according to a divine rule, but as a contract established at birth between the citizen and the society, it is the social contract. From that moment on, capital punishment should be seen as useful to society through its dissuasive effect, but also as a means of protection of the latter vis-à-vis criminals.
In the last several centuries, with the emergence of modern nation states, justice came to be increasingly associated with the concept of natural and legal rights. The period saw an increase in standing police forces and permanent penitential institutions. Rational choice theory, a utilitarian approach to criminology which justifies punishment as a form of deterrence as opposed to retribution, can be traced back to Cesare Beccaria, whose influential treatise On Crimes and Punishments (1764) was the first detailed analysis of capital punishment to demand the abolition of the death penalty. In England, Jeremy Bentham (1748–1832), the founder of modern utilitarianism, called for the abolition of the death penalty. Beccaria, and later Charles Dickens and Karl Marx noted the incidence of increased violent criminality at the times and places of executions. Official recognition of this phenomenon led to executions being carried out inside prisons, away from public view.
In England in the 18th century, when there was no police force, Parliament drastically increased the number of capital offences to more than 200. These were mainly property offences, for example cutting down a cherry tree in an orchard. In 1820, there were 160, including crimes such as shoplifting, petty theft or stealing cattle. The severity of the so-called Bloody Code was often tempered by juries who refused to convict, or judges, in the case of petty theft, who arbitrarily set the value stolen at below the statutory level for a capital crime.
In Nazi Germany, there were three types of capital punishment; hanging, decapitation, and death by shooting. Also, modern military organisations employed capital punishment as a means of maintaining military discipline. In the past, cowardice, absence without leave, desertion, insubordination, shirking under enemy fire and disobeying orders were often crimes punishable by death (see decimation and running the gauntlet). One method of execution, since firearms came into common use, has also been firing squad, although some countries use execution with a single shot to the head or neck.
Various authoritarian states—for example those with Fascist or Communist governments—employed the death penalty as a potent means of political oppression. According to Robert Conquest, the leading expert on Joseph Stalin's purges, more than one million Soviet citizens were executed during the Great Purge of 1936 to 1938, almost all by a bullet to the back of the head. Mao Zedong publicly stated that "800,000" people had been executed in China during the Cultural Revolution (1966–1976). Partly as a response to such excesses, civil rights organisations started to place increasing emphasis on the concept of human rights and an abolition of the death penalty.
By continent, all European states but one have abolished capital punishment; many Oceanian states have abolished it; most states in the Americas have abolished its use, while a few actively retain it; less than half of countries in Africa retain it; and the majority of countries in Asia retain it.
Abolition was often adopted due to political change, as when countries shifted from authoritarianism to democracy, or when it became an entry condition for the EU. The United States is a notable exception: some states have had bans on capital punishment for decades, the earliest being Michigan, where it was abolished in 1846, while other states still actively use it today. The death penalty in the United States remains a contentious issue which is hotly debated.
In retentionist countries, the debate is sometimes revived when a miscarriage of justice has occurred though this tends to cause legislative efforts to improve the judicial process rather than to abolish the death penalty. In abolitionist countries, the debate is sometimes revived by particularly brutal murders, though few countries have brought it back after abolishing it. However, a spike in serious, violent crimes, such as murders or terrorist attacks, has prompted some countries to effectively end the moratorium on the death penalty. One notable example is Pakistan which in December 2014 lifted a six-year moratorium on executions after the Peshawar school massacre during which 132 students and 9 members of staff of the Army Public School and Degree College Peshawar were killed by Tehrik-i-Taliban Pakistan terrorists, a group distinct from the Afghan Taliban, who condemned the attack. Since then, Pakistan has executed over 400 convicts.
In 2017, two major countries, Turkey and the Philippines, saw their executives making moves to reinstate the death penalty. In the same year, passage of the law in the Philippines failed to obtain the Senate's approval.
On 29 December 2021, after a 20-year moratorium, the Kazakhstan government enacted the 'On Amendments and Additions to Certain Legislative Acts of the Republic of Kazakhstan on the Abolition of the Death Penalty' signed by President Kassym-Jomart Tokayev as part of series of Omnibus reformations of the Kazak legal system 'Listening State' initiative.
In 724 AD in Japan, the death penalty was banned during the reign of Emperor Shōmu but the abolition only lasted a few years. In 818, Emperor Saga abolished the death penalty under the influence of Shinto and it lasted until 1156. In China, the death penalty was banned by Emperor Xuanzong of Tang in 747, replacing it with exile or scourging. However, the ban only lasted 12 years. Following his conversion to Christianity in 988, Vladimir the Great abolished the death penalty in Kievan Rus', along with torture and mutilation; corporal punishment was also seldom used.
In England, a public statement of opposition was included in The Twelve Conclusions of the Lollards, written in 1395. Sir Thomas More's Utopia, published in 1516, debated the benefits of the death penalty in dialogue form, coming to no firm conclusion. More was himself executed for treason in 1535.
More recent opposition to the death penalty stemmed from the book of the Italian Cesare Beccaria Dei Delitti e Delle Pene ("On Crimes and Punishments"), published in 1764. In this book, Beccaria aimed to demonstrate not only the injustice, but even the futility from the point of view of social welfare, of torture and the death penalty. Influenced by the book, Grand Duke Leopold II of Habsburg, the future Emperor of Austria, abolished the death penalty in the then-independent Grand Duchy of Tuscany, the first permanent abolition in modern times. On 30 November 1786, after having de facto blocked executions (the last was in 1769), Leopold promulgated the reform of the penal code that abolished the death penalty and ordered the destruction of all the instruments for capital execution in his land. In 2000, Tuscany's regional authorities instituted an annual holiday on 30 November to commemorate the event. The event is commemorated on this day by 300 cities around the world celebrating Cities for Life Day. In the United Kingdom, it was abolished for murder (leaving only treason, piracy with violence, arson in royal dockyards and a number of wartime military offences as capital crimes) for a five-year experiment in 1965 and permanently in 1969, the last execution having taken place in 1964. It was abolished for all offences in 1998. Protocol 13 to the European Convention on Human Rights, first entering into force in 2003, prohibits the death penalty in all circumstances for those states that are party to it, including the United Kingdom from 2004.
In the post-classical Republic of Poljica, life was ensured as a basic right in its Poljica Statute of 1440. The short-lived revolutionary Roman Republic banned capital punishment in 1849. Venezuela followed suit and abolished the death penalty in 1863 and San Marino did so in 1865. The last execution in San Marino had taken place in 1468. In Portugal, after legislative proposals in 1852 and 1863, the death penalty was abolished in 1867. The last execution in Brazil was 1876; from then on all the condemnations were commuted by the Emperor Pedro II until its abolition for civil offences and military offences in peacetime in 1891. The penalty for crimes committed in peacetime was then reinstated and abolished again twice (1938–1953 and 1969–1978), but on those occasions it was restricted to acts of terrorism or subversion considered "internal warfare" and all sentences were commuted and not carried out.
Abolition occurred in Canada in 1976 (except for some military offences, with complete abolition in 1998); in France in 1981; and in Australia in 1973 (although the state of Western Australia retained the penalty until 1984). In South Australia, under the premiership of then-Premier Dunstan, the Criminal Law Consolidation Act 1935 (SA) was modified so that the death sentence was changed to life imprisonment in 1976.
In 1977, the United Nations General Assembly affirmed in a formal resolution that throughout the world, it is desirable to "progressively restrict the number of offences for which the death penalty might be imposed, with a view to the desirability of abolishing this punishment".
In the United States, Michigan was the first state to ban the death penalty, on 18 May 1846. The death penalty was declared unconstitutional between 1972 and 1976 based on the Furman v. Georgia case, but the 1976 Gregg v. Georgia case once again permitted the death penalty under certain circumstances. Further limitations were placed on the death penalty in Atkins v. Virginia (2002; death penalty unconstitutional for people with an intellectual disability) and Roper v. Simmons (2005; death penalty unconstitutional if defendant was under age 18 at the time the crime was committed). In the United States, 23 of the 50 states and Washington, D.C. ban capital punishment.
Many countries have abolished capital punishment either in law or in practice. Since World War II, there has been a trend toward abolishing capital punishment. Capital punishment has been completely abolished by 108 countries, a further seven have done so for all offences except under special circumstances and 26 more have abolished it in practice because they have not used it for at least 10 years and are believed to have a policy or established practice against carrying out executions.
Most nations, including almost all developed countries, have abolished capital punishment either in law or in practice; notable exceptions are the United States, Japan, Taiwan, and Singapore. Additionally, capital punishment is also carried out in China, India, and most Islamic states.
Since World War II, there has been a trend toward abolishing the death penalty. 54 countries retain the death penalty in active use, 112 countries have abolished capital punishment altogether, 7 have done so for all offences except under special circumstances, and 22 more have abolished it in practice because they have not used it for at least 10 years and are believed to have a policy or established practice against carrying out executions.
According to Amnesty International, 20 countries are known to have performed executions in 2022. There are countries which do not publish information on the use of capital punishment, most significantly China and North Korea. According to Amnesty International, around 1,000 prisoners were executed in 2017. Amnesty reported in 2004 and 2009 that Singapore and Iraq respectively had the world's highest per capita execution rate. According to Al Jazeera and UN Special Rapporteur Ahmed Shaheed, Iran has had the world's highest per capita execution rate. A 2012 EU report from the Directorate-General for External Relations' policy department pointed to Gaza as having the highest per capita execution rate in the MENA region.
The use of the death penalty is becoming increasingly restrained in some retentionist countries including Taiwan and Singapore. Indonesia carried out no executions between November 2008 and March 2013. Singapore, Japan and the United States are the only developed countries that are classified by Amnesty International as 'retentionist' (South Korea is classified as 'abolitionist in practice'). Nearly all retentionist countries are situated in Asia, Africa and the Caribbean. The only retentionist country in Europe is Belarus. During the 1980s, the democratisation of Latin America swelled the ranks of abolitionist countries.
This was soon followed by the fall of communism in Europe. Many of the countries which restored democracy aspired to enter the EU. The EU and the Council of Europe both strictly require member states not to practice the death penalty (see Capital punishment in Europe). Public support for the death penalty in the EU varies. The last execution in a member state of the present-day Council of Europe took place in 1997 in Ukraine. In contrast, the rapid industrialisation in Asia has seen an increase in the number of developed countries which are also retentionist. In these countries, the death penalty retains strong public support, and the matter receives little attention from the government or the media; in China there is a small but significant and growing movement to abolish the death penalty altogether. This trend has been followed by some African and Middle Eastern countries where support for the death penalty remains high.
Some countries have resumed practising the death penalty after having previously suspended the practice for long periods. The United States suspended executions in 1972 but resumed them in 1976; there was no execution in India between 1995 and 2004; and Sri Lanka declared an end to its moratorium on the death penalty on 20 November 2004, although it has not yet performed any further executions. The Philippines re-introduced the death penalty in 1993 after abolishing it in 1987, but again abolished it in 2006.
The United States and Japan are the only developed countries to have recently carried out executions. The U.S. federal government, the U.S. military, and 27 states have a valid death penalty statute, and over 1,400 executions have been carried in the United States since it reinstated the death penalty in 1976. Japan has 107 inmates with finalized death sentences as of August 24, 2023, after Toshihiko Iwama, who was convicted of hiring assassin to murder two Japanese businessmen in Manila, Philippines in 2014 and 2015, died of diabetic symptoms at Tokyo Detention House.
The most recent country to abolish the death penalty was Kazakhstan on 2 January 2021 after a moratorium dating back 2 decades.
According to an Amnesty International report released in April 2020, Egypt ranked regionally third and globally fifth among the countries that carried out most executions in 2019. The country increasingly ignored international human rights concerns and criticism. In March 2021, Egypt executed 11 prisoners in a jail, who were convicted in cases of "murder, theft, and shooting".
According to Amnesty International's 2021 report, at least 483 people were executed in 2020 despite the COVID-19 pandemic. The figure excluded the countries that classify death penalty data as state secret. The top five executioners for 2020 were China, Iran, Egypt, Iraq and Saudi Arabia.
The public opinion on the death penalty varies considerably by country and by the crime in question. Countries where a majority of people are against execution include Norway, where only 25% support it. Most French, Finns, and Italians also oppose the death penalty. In 2020, 55% of Americans supported the death penalty for an individual convicted of murder, down from 60% in 2016, 64% in 2010, 65% in 2006, and 68% in 2001. In 2020, 43% of Italians expressed support for the death penalty.
In Taiwan, polls and research have consistently shown strong support for the death penalty at 80%. This includes a survey conducted by the National Development Council of Taiwan in 2016, showing that 88% of Taiwanese people disagree with abolishing the death penalty. Its continuation of the practice drew criticism from local rights groups.
The support and sentencing of capital punishment has been growing in India in the 2010s due to anger over several recent brutal cases of rape, even though actual executions are comparatively rare. While support for the death penalty for murder is still high in China, executions have dropped precipitously, with 3,000 executed in 2012 versus 12,000 in 2002. A poll in South Africa, where capital punishment is abolished, found that 76% of millennial South Africans support re-introduction of the death penalty due to increasing incidents of rape and murder. A 2017 poll found younger Mexicans are more likely to support capital punishment than older ones. 57% of Brazilians support the death penalty. The age group that shows the greatest support for execution of those condemned is the 25 to 34-year-old category, in which 61% say they support it.
A 2023 poll by Research Co. found that 54 percent of Canadians support reinstating the death penalty for murder in their country. In April 2021 a poll found that 54% of Britons said they would support reinstating the death penalty for those convicted of terrorism in the UK. About a quarter (23%) of respondents said they would be opposed. In 2020, an Ipsos/Sopra Steria survey showed that 55% of the French people support re-introduction of the death penalty; this was an increase from 44% in 2019.
The death penalty for juvenile offenders (criminals aged under 18 years at the time of their crime although the legal or accepted definition of juvenile offender may vary from one jurisdiction to another) has become increasingly rare. Considering the age of majority is not 18 in some countries or has not been clearly defined in law, since 1990 ten countries have executed offenders who were considered juveniles at the time of their crimes: The People's Republic of China (PRC), Bangladesh, Democratic Republic of Congo, Iran, Iraq, Japan, Nigeria, Pakistan, Saudi Arabia, Sudan, the United States, and Yemen. China, Pakistan, the United States, Saudi Arabia, and Yemen have since raised the minimum age to 18. Amnesty International has recorded 61 verified executions since then, in several countries, of both juveniles and adults who had been convicted of committing their offences as juveniles. The PRC does not allow for the execution of those under 18, but child executions have reportedly taken place.
One of the youngest children ever to be executed was the infant son of Perotine Massey on or around 18 July 1556. His mother was one of the Guernsey Martyrs who was executed for heresy, and his father had previously fled the island. At less than one day old, he was ordered to be burned by Bailiff Hellier Gosselin, with the advice of priests nearby who said the boy should burn due to having inherited moral stain from his mother, who had given birth during her execution.
Starting from 1642 in Colonial America until the present day in the United States, an estimated 365 juvenile offenders were executed by various colonial authorities and (after the American Revolution) the federal government. The U.S. Supreme Court abolished capital punishment for offenders under the age of 16 in Thompson v. Oklahoma (1988), and for all juveniles in Roper v. Simmons (2005).
In Prussia, children under the age of 14 were exempted from the death penalty in 1794. Capital punishment was cancelled by the Electorate of Bavaria in 1751 for children under the age of 11 and by the Kingdom of Bavaria in 1813 for children and youth under 16 years. In Prussia, the exemption was extended to youth under the age of 16 in 1851. For the first time, all juveniles were excluded for the death penalty by the North German Confederation in 1871, which was continued by the German Empire in 1872. In Nazi Germany, capital punishment was reinstated for juveniles between 16 and 17 years in 1939. This was broadened to children and youth from age 12 to 17 in 1943. The death penalty for juveniles was abolished by West Germany, also generally, in 1949 and by East Germany in 1952.
In the Hereditary Lands, Austrian Silesia, Bohemia and Moravia within the Habsburg monarchy, capital punishment for children under the age of 11 was no longer foreseen by 1770. The death penalty was, also for juveniles, nearly abolished in 1787 except for emergency or military law, which is unclear in regard of those. It was reintroduced for juveniles above 14 years by 1803, and was raised by general criminal law to 20 years in 1852 and this exemption and the alike one of military law in 1855, which may have been up to 14 years in wartime, were also introduced into all of the Austrian Empire.
In the Helvetic Republic, the death penalty for children and youth under the age of 16 was abolished in 1799 yet the country was already dissolved in 1803 whereas the law could remain in force if it was not replaced on cantonal level. In the canton of Bern, all juveniles were exempted from the death penalty at least in 1866. In Fribourg, capital punishment was generally, including for juveniles, abolished by 1849. In Ticino, it was abolished for youth and young adults under the age of 20 in 1816. In Zurich, the exclusion from the death penalty was extended for juveniles and young adults up to 19 years of age by 1835. In 1942, the death penalty was almost deleted in criminal law, as well for juveniles, but since 1928 persisted in military law during wartime for youth above 14 years. If no earlier change was made in the given subject, by 1979 juveniles could no longer be subject to the death penalty in military law during wartime.
Between 2005 and May 2008, Iran, Pakistan, Saudi Arabia, Sudan and Yemen were reported to have executed child offenders, the largest number occurring in Iran.
During Hassan Rouhani's tenure as president of Iran from 2013 until 2021, at least 3,602 death sentences have been carried out. This includes the executions of 34 juvenile offenders.
The United Nations Convention on the Rights of the Child, which forbids capital punishment for juveniles under article 37(a), has been signed by all countries and subsequently ratified by all signatories with the exception of the United States (despite the US Supreme Court decisions abolishing the practice). The UN Sub-Commission on the Promotion and Protection of Human Rights maintains that the death penalty for juveniles has become contrary to a jus cogens of customary international law. A majority of countries are also party to the U.N. International Covenant on Civil and Political Rights (whose Article 6.5 also states that "Sentence of death shall not be imposed for crimes committed by persons below eighteen years of age...").
Iran, despite its ratification of the Convention on the Rights of the Child and International Covenant on Civil and Political Rights, was the world's largest executioner of juvenile offenders, for which it has been the subject of broad international condemnation; the country's record is the focus of the Stop Child Executions Campaign. But on 10 February 2012, Iran's parliament changed controversial laws relating to the execution of juveniles. In the new legislation the age of 18 (solar year) would be applied to accused of both genders and juvenile offenders must be sentenced pursuant to a separate law specifically dealing with juveniles. Based on the Islamic law which now seems to have been revised, girls at the age of 9 and boys at 15 of lunar year (11 days shorter than a solar year) are deemed fully responsible for their crimes. Iran accounted for two-thirds of the global total of such executions, and currently has approximately 140 people considered as juveniles awaiting execution for crimes committed (up from 71 in 2007). The past executions of Mahmoud Asgari, Ayaz Marhoni and Makwan Moloudzadeh became the focus of Iran's child capital punishment policy and the judicial system that hands down such sentences. In 2023 Iran executed a minor who had knifed a guy that fought him for following a girl in the street.
Saudi Arabia also executes criminals who were minors at the time of the offence. In 2013, Saudi Arabia was the center of an international controversy after it executed Rizana Nafeek, a Sri Lankan domestic worker, who was believed to have been 17 years old at the time of the crime. Saudi Arabia banned execution for minors, except for terrorism cases, in April 2020.
Japan has not executed juvenile criminals after August 1997, when they executed Norio Nagayama, a spree killer who had been convicted of shooting four people dead in the late 1960s. Nagayama's case created the eponymously named Nagayama standards, which take into account factors such as the number of victims, brutality and social impact of the crimes. The standards have been used in determining whether to apply the death sentence in murder cases. Teruhiko Seki, convicted of murdering four family members including a 4-year-old daughter and raping a 15-year-old daughter of a family in 1992, became the second inmate to be hanged for a crime committed as a minor in the first such execution in 20 years after Nagayama on 19 December 2017. Takayuki Otsuki, who was convicted of raping and strangling a 23-year-old woman and subsequently strangling her 11-month-old daughter to death on 14 April 1999, when he was 18, is another inmate sentenced to death, and his request for retrial has been rejected by the Supreme Court of Japan.
There is evidence that child executions are taking place in the parts of Somalia controlled by the Islamic Courts Union (ICU). In October 2008, a girl, Aisha Ibrahim Dhuhulow was buried up to her neck at a football stadium, then stoned to death in front of more than 1,000 people. Somalia's established Transitional Federal Government announced in November 2009 (reiterated in 2013) that it plans to ratify the Convention on the Rights of the Child. This move was lauded by UNICEF as a welcome attempt to secure children's rights in the country.
The following methods of execution have been used by various countries:
A public execution is a form of capital punishment which "members of the general public may voluntarily attend". This definition excludes the presence of a small number of witnesses randomly selected to assure executive accountability. While today the great majority of the world considers public executions to be distasteful and most countries have outlawed the practice, throughout much of history executions were performed publicly as a means for the state to demonstrate "its power before those who fell under its jurisdiction be they criminals, enemies, or political opponents". Additionally, it afforded the public a chance to witness "what was considered a great spectacle".
Social historians note that beginning in the 20th century in the U.S. and western Europe, death in general became increasingly shielded from public view, occurring more and more behind the closed doors of the hospital. Executions were likewise moved behind the walls of the penitentiary. The last formal public executions occurred in 1868 in Britain, in 1936 in the U.S. and in 1939 in France.
According to Amnesty International, in 2012, "public executions were known to have been carried out in Iran, North Korea, Saudi Arabia and Somalia". There have been reports of public executions carried out by state and non-state actors in Hamas-controlled Gaza, Syria, Iraq, Afghanistan, and Yemen. Executions which can be classified as public were also carried out in the U.S. states of Florida and Utah as of 1992.
Crimes against humanity such as genocide are usually punishable by death in countries retaining capital punishment. Death sentences for such crimes were handed down and carried out during the Nuremberg Trials in 1946 and the Tokyo Trials in 1948, but the current International Criminal Court does not use capital punishment. The maximum penalty available to the International Criminal Court is life imprisonment.
Intentional homicide is punishable by death in most countries retaining capital punishment, but generally provided it involves an aggravating factor required by statute or judicial precedents.
Some countries, including Singapore and Malaysia, made the death penalty mandatory for murder, though Singapore later changed its laws since 2013 to reserve the mandatory death sentence for intentional murder while providing an alternative sentence of life imprisonment with/without caning for murder with no intention to cause death, which allowed some convicted murderers on death row in Singapore (including Kho Jabing) to apply for the reduction of their death sentences after the courts in Singapore confirmed that they committed murder without the intention to kill and thus eligible for re-sentencing under the new death penalty laws in Singapore. In October 2018 the Malaysian Government imposed a moratorium on all executions until the passage of a new law that would abolish the death penalty. In April 2023, legislation abolishing the mandatory death penalty was passed in Malaysia. The death penalty would be retained, but courts have the discretion to replace it with other punishments, including whipping and imprisonment of 30–40 years.
In 2018, at least 35 countries retained the death penalty for drug trafficking, drug dealing, drug possession and related offences. People had been regularly sentenced to death and executed for drug-related offences in China, Indonesia, Iran, Malaysia, Saudi Arabia, Singapore and Vietnam. Other countries may retain the death penalty for symbolic purposes.
The death penalty was mandated for drug trafficking in Singapore and Malaysia. Since 2013, Singapore ruled that those who were certified to have diminished responsibility (e.g. Major depressive disorder) or acting as drug couriers and had assisted the authorities in tackling drug-related activities, would be sentenced to life imprisonment instead of death, with the offender liable to at least 15 strokes of the cane if he was not sentenced to death and was simultaneously sentenced to caning as well. Drug courier Yong Vui Kong's death sentence was replaced with a life sentence and 15 strokes of the cane in November 2013. In April 2023, legislation abolishing the mandatory death penalty was passed in Malaysia.
Other crimes that are punishable by death in some countries include:
Death penalty opponents regard the death penalty as inhumane and criticize it for its irreversibility. They argue also that capital punishment lacks deterrent effect, or has a brutalization effect, discriminates against minorities and the poor, and that it encourages a "culture of violence". There are many organizations worldwide, such as Amnesty International, and country-specific, such as the American Civil Liberties Union (ACLU), that have abolition of the death penalty as its main purpose.
Advocates of the death penalty argue that it deters crime, is a good tool for police and prosecutors in plea bargaining, makes sure that convicted criminals do not offend again, and that it ensures justice for crimes such as homicide, where other penalties will not inflict the desired retribution demanded by the crime itself. Capital punishment for non-lethal crimes is usually considerably more controversial, and abolished in many of the countries that retain it.
Supporters of the death penalty argued that death penalty is morally justified when applied in murder especially with aggravating elements such as for murder of police officers, child murder, torture murder, multiple homicide and mass killing such as terrorism, massacre and genocide. This argument is strongly defended by New York Law School's Professor Robert Blecker, who says that the punishment must be painful in proportion to the crime. Eighteenth-century philosopher Immanuel Kant defended a more extreme position, according to which every murderer deserves to die on the grounds that loss of life is incomparable to any penalty that allows them to remain alive, including life imprisonment.
Some abolitionists argue that retribution is simply revenge and cannot be condoned. Others while accepting retribution as an element of criminal justice nonetheless argue that life without parole is a sufficient substitute. It is also argued that the punishing of a killing with another death is a relatively unusual punishment for a violent act, because in general violent crimes are not punished by subjecting the perpetrator to a similar act (e.g. rapists are, typically, not punished by corporal punishment, although it may be inflicted in Singapore, for example).
Abolitionists believe capital punishment is the worst violation of human rights, because the right to life is the most important, and capital punishment violates it without necessity and inflicts to the condemned a psychological torture. Human rights activists oppose the death penalty, calling it "cruel, inhuman and degrading punishment". Amnesty International considers it to be "the ultimate irreversible denial of Human Rights". Albert Camus wrote in a 1956 book called Reflections on the Guillotine, Resistance, Rebellion & Death:
An execution is not simply death. It is just as different from the privation of life as a concentration camp is from prison. [...] For there to be an equivalency, the death penalty would have to punish a criminal who had warned his victim of the date at which he would inflict a horrible death on him and who, from that moment onward, had confined him at his mercy for months. Such a monster is not encountered in private life.
In the classic doctrine of natural rights as expounded by for instance Locke and Blackstone, on the other hand, it is an important idea that the right to life can be forfeited, as most other rights can be given due process is observed, such as the right to property and the right to freedom, including provisionally, in anticipation of an actual verdict. As John Stuart Mill explained in a speech given in Parliament against an amendment to abolish capital punishment for murder in 1868:
And we may imagine somebody asking how we can teach people not to inflict suffering by ourselves inflicting it? But to this I should answer – all of us would answer – that to deter by suffering from inflicting suffering is not only possible, but the very purpose of penal justice. Does fining a criminal show want of respect for property, or imprisoning him, for personal freedom? Just as unreasonable is it to think that to take the life of a man who has taken that of another is to show want of regard for human life. We show, on the contrary, most emphatically our regard for it, by the adoption of a rule that he who violates that right in another forfeits it for himself, and that while no other crime that he can commit deprives him of his right to live, this shall.
In one of the most recent cases relating to the death penalty in Singapore, activists like Jolovan Wham, Kirsten Han and Kokila Annamalai and even the international groups like the United Nations and European Union argued for Malaysian drug trafficker Nagaenthran K. Dharmalingam, who has been on death row at Singapore's Changi Prison since 2010, should not be executed due to an alleged intellectual disability, as they argued that Nagaenthran has low IQ of 69 and a psychiatrist has assessed him to be mentally impaired to an extent that he should not be held liable to his crime and execution. They also cited international law where a country should be prohibiting the execution of mentally and intellectually impaired people in order to push for Singapore to commute Nagaenthran's death penalty to life imprisonment based on protection of human rights. However, the Singapore government and both Singapore's High Court and Court of Appeal maintained their firm stance that despite his certified low IQ, it is confirmed that Nagaenthran is not mentally or intellectually disabled based on the joint opinion of three government psychiatrists as he is able to fully understand the magnitude of his actions and has no problem in his daily functioning of life. Despite the international outcry, Nagaenthran was executed on 27 April 2022.
Trends in most of the world have long been to move to private and less painful executions. France developed the guillotine for this reason in the final years of the 18th century, while Britain banned hanging, drawing, and quartering in the early 19th century. Hanging by turning the victim off a ladder or by kicking a stool or a bucket, which causes death by strangulation, was replaced by long drop "hanging" where the subject is dropped a longer distance to dislocate the neck and sever the spinal cord. Mozaffar ad-Din Shah Qajar, Shah of Persia (1896–1907) introduced throat-cutting and blowing from a gun (close-range cannon fire) as quick and relatively painless alternatives to more torturous methods of executions used at that time. In the United States, electrocution and gas inhalation were introduced as more humane alternatives to hanging, but have been almost entirely superseded by lethal injection. A small number of countries, for example Iran and Saudi Arabia, still employ slow hanging methods, decapitation, and stoning.
A study of executions carried out in the United States between 1977 and 2001 indicated that at least 34 of the 749 executions, or 4.5%, involved "unanticipated problems or delays that caused, at least arguably, unnecessary agony for the prisoner or that reflect gross incompetence of the executioner". The rate of these "botched executions" remained steady over the period of the study. A separate study published in The Lancet in 2005 found that in 43% of cases of lethal injection, the blood level of hypnotics was insufficient to guarantee unconsciousness. However, the U.S. Supreme Court ruled in 2008 (Baze v. Rees) and again in 2015 (Glossip v. Gross) that lethal injection does not constitute cruel and unusual punishment. In Bucklew v. Precythe, the majority verdict – written by Judge Neil Gorsuch – further affirmed this principle, stating that while the ban on cruel and unusual punishment affirmatively bans penalties that deliberately inflict pain and degradation, it does in no sense limit the possible infliction of pain in the execution of a capital verdict.
It is frequently argued that capital punishment leads to miscarriage of justice through the wrongful execution of innocent persons. Many people have been proclaimed innocent victims of the death penalty.
Some have claimed that as many as 39 executions have been carried out in the face of compelling evidence of innocence or serious doubt about guilt in the US from 1992 through 2004. Newly available DNA evidence prevented the pending execution of more than 15 death row inmates during the same period in the US, but DNA evidence is only available in a fraction of capital cases. As of 2017, 159 prisoners on death row have been exonerated by DNA or other evidence, which is seen as an indication that innocent prisoners have almost certainly been executed. The National Coalition to Abolish the Death Penalty claims that between 1976 and 2015, 1,414 prisoners in the United States have been executed while 156 sentenced to death have had their death sentences vacated. It is impossible to assess how many have been wrongly executed, since courts do not generally investigate the innocence of a dead defendant, and defense attorneys tend to concentrate their efforts on clients whose lives can still be saved; however, there is strong evidence of innocence in many cases.
Improper procedure may also result in unfair executions. For example, Amnesty International argues that in Singapore "the Misuse of Drugs Act contains a series of presumptions which shift the burden of proof from the prosecution to the accused. This conflicts with the universally guaranteed right to be presumed innocent until proven guilty". Singapore's Misuse of Drugs Act presumes one is guilty of possession of drugs if, as examples, one is found to be present or escaping from a location "proved or presumed to be used for the purpose of smoking or administering a controlled drug", if one is in possession of a key to a premises where drugs are present, if one is in the company of another person found to be in possession of illegal drugs, or if one tests positive after being given a mandatory urine drug screening. Urine drug screenings can be given at the discretion of police, without requiring a search warrant. The onus is on the accused in all of the above situations to prove that they were not in possession of or consumed illegal drugs.
Some prisoners have volunteered or attempted to expedite capital punishment, often by waiving all appeals. Prisoners have made requests or committed further crimes in prison as well. In the United States, execution volunteers constitute approximately 11% of prisoners on death row. Volunteers often bypass legal procedures which are designed to designate the death penalty for the "worst of the worst" offenders. Opponents of execution volunteering cited the prevalence of mental illness among volunteers comparing it to suicide. Execution volunteers have received considerably less attention and effort at legal reform than those who were exonerated after execution.
Opponents of the death penalty argue that this punishment is being used more often against perpetrators from racial and ethnic minorities and from lower socioeconomic backgrounds, than against those criminals who come from a privileged background; and that the background of the victim also influences the outcome. Researchers have shown that white Americans are more likely to support the death penalty when told that it is mostly applied to black Americans, and that more stereotypically black-looking or dark-skinned defendants are more likely to be sentenced to death if the case involves a white victim. However, a study published in 2018 failed to replicate the findings of earlier studies that had concluded that white Americans are more likely to support the death penalty if informed that it is largely applied to black Americans; according to the authors, their findings "may result from changes since 2001 in the effects of racial stimuli on white attitudes about the death penalty or their willingness to express those attitudes in a survey context."
In Alabama in 2019, a death row inmate named Domineque Ray was denied his imam in the room during his execution, instead only offered a Christian chaplain. After filing a complaint, a federal court of appeals ruled 5–4 against Ray's request. The majority cited the "last-minute" nature of the request, and the dissent stated that the treatment went against the core principle of denominational neutrality.
In July 2019, two Shiite men, Ali Hakim al-Arab, 25, and Ahmad al-Malali, 24, were executed in Bahrain, despite the protests from the United Nations and rights group. Amnesty International stated that the executions were being carried out on confessions of "terrorism crimes" that were obtained through torture.
On 30 March 2022, despite the appeals by the United Nations and rights activists, 68-year-old Malay Singaporean Abdul Kahar Othman was hanged at Singapore's Changi Prison for illegally trafficking diamorphine, which marked the first execution in Singapore since 2019 as a result of an informal moratorium caused by the COVID-19 pandemic. Earlier, there were appeals made to advocate for Abdul Kahar's death penalty be commuted to life imprisonment on humanitarian grounds, as Abdul Kahar came from a poor family and has struggled with drug addiction. He was also revealed to have been spending most of his life going in and out of prison, including a ten-year sentence of preventive detention from 1995 to 2005, and has not been given much time for rehabilitation, which made the activists and groups arguing that Abdul Kahar should be given a chance for rehabilitation instead of subjecting him to execution. Both the European Union (EU) and Amnesty International criticised Singapore for finalizing and carrying out Abdul Kahar's execution, and about 400 Singaporeans protested against the government's use of the death penalty merely days after Abdul Kahar's death sentence was authorised. Still, over 80% of the public supported the use of the death penalty in Singapore.
The United Nations introduced a resolution during the General Assembly's 62nd sessions in 2007 calling for a universal ban. The approval of a draft resolution by the Assembly's third committee, which deals with human rights issues, voted 99 to 52, with 33 abstentions, in support of the resolution on 15 November 2007 and was put to a vote in the Assembly on 18 December.
Again in 2008, a large majority of states from all regions adopted, on 20 November in the UN General Assembly (Third Committee), a second resolution calling for a moratorium on the use of the death penalty; 105 countries voted in support of the draft resolution, 48 voted against and 31 abstained.
The moratorium resolution has been presented for a vote each year since 2007. On December 15, 2022, 125 countries voted in support of the moratorium, with 37 countries opposing, and 22 abstentions. The countries voting against the moratorium included the United States, People's Republic of China, North Korea, and Iran.
A range of amendments proposed by a small minority of pro-death penalty countries were overwhelmingly defeated. It had in 2007 passed a non-binding resolution (by 104 to 54, with 29 abstentions) by asking its member states for "a moratorium on executions with a view to abolishing the death penalty".
A number of regional conventions prohibit the death penalty, most notably, the Protocol 6 (abolition in time of peace) and Protocol 13 (abolition in all circumstances) to the European Convention on Human Rights. The same is also stated under Protocol 2 in the American Convention on Human Rights, which, however, has not been ratified by all countries in the Americas, most notably Canada and the United States. Most relevant operative international treaties do not require its prohibition for cases of serious crime, most notably, the International Covenant on Civil and Political Rights. This instead has, in common with several other treaties, an optional protocol prohibiting capital punishment and promoting its wider abolition.
Several international organizations have made abolition of the death penalty (during time of peace, or in all circumstances) a requirement of membership, most notably the EU and the Council of Europe. The Council of Europe are willing to accept a moratorium as an interim measure. Thus, while Russia was a member of the Council of Europe, and the death penalty remains codified in its law, it has not made use of it since becoming a member of the council – Russia has not executed anyone since 1996. With the exception of Russia (abolitionist in practice) and Belarus (retentionist), all European countries are classified as abolitionist.
Latvia abolished de jure the death penalty for war crimes in 2012, becoming the last EU member to do so.
Protocol 13 to the European Convention on Human Rights calls for the abolition of the death penalty in all circumstances (including for war crimes). The majority of European countries have signed and ratified it. Some European countries have not done this, but all of them except Belarus have now abolished the death penalty in all circumstances (de jure, and Russia de facto). Poland is the most recent country to ratify the protocol, on 28 August 2013.
Protocol 6, which prohibits the death penalty during peacetime, has been ratified by all members of the Council of Europe. It had been signed but not ratified by Russia at the time of its expulsion in 2022.
There are also other international abolitionist instruments, such as the Second Optional Protocol to the International Covenant on Civil and Political Rights, which has 90 parties; and the Protocol to the American Convention on Human Rights to Abolish the Death Penalty (for the Americas; ratified by 13 states).
In Turkey, over 500 people were sentenced to death after the 1980 Turkish coup d'état. About 50 of them were executed, the last one 25 October 1984. Then there was a de facto moratorium on the death penalty in Turkey. As a move towards EU membership, Turkey made some legal changes. The death penalty was removed from peacetime law by the National Assembly in August 2002, and in May 2004 Turkey amended its constitution to remove capital punishment in all circumstances. It ratified Protocol 13 to the European Convention on Human Rights in February 2006. As a result, Europe is a continent free of the death penalty in practice, all states, having ratified Protocol 6 to the European Convention on Human Rights, with the exceptions of Russia (which has entered a moratorium) and Belarus, which are not members of the Council of Europe. The Parliamentary Assembly of the Council of Europe has been lobbying for Council of Europe observer states who practice the death penalty, the U.S. and Japan, to abolish it or lose their observer status. In addition to banning capital punishment for EU member states, the EU has also banned detainee transfers in cases where the receiving party may seek the death penalty.
Sub-Saharan African countries that have recently abolished the death penalty include Burundi, which abolished the death penalty for all crimes in 2009, and Gabon which did the same in 2010. On 5 July 2012, Benin became part of the Second Optional Protocol to the International Covenant on Civil and Political Rights (ICCPR), which prohibits the use of the death penalty.
The newly created South Sudan is among the 111 UN member states that supported the resolution passed by the United Nations General Assembly that called for the removal of the death penalty, therefore affirming its opposition to the practice. South Sudan, however, has not yet abolished the death penalty and stated that it must first amend its Constitution, and until that happens it will continue to use the death penalty.
Among non-governmental organizations (NGOs), Amnesty International and Human Rights Watch are noted for their opposition to capital punishment. A number of such NGOs, as well as trade unions, local councils, and bar associations, formed a World Coalition Against the Death Penalty in 2002.
An open letter led by Danish Member of the European Parliament, Karen Melchior was sent to the European Commission ahead of the 26 January 2021 meeting of the Bahraini Minister of Foreign Affairs, Abdullatif bin Rashid Al Zayani with the members of the European Union for the signing of a Cooperation Agreement. A total of 16 MEPs undersigned the letter expressing their grave concern towards the extended abuse of human rights in Bahrain following the arbitrary arrest and detention of activists and critics of the government. The attendees of the meeting were requested to demand from their Bahraini counterparts to take into consideration the concerns raised by the MEPs, particularly for the release of Abdulhadi Al-Khawaja and Sheikh Mohammed Habib Al-Muqdad, the two European-Bahraini dual citizens on death row.
The world's major faiths have differing views depending on the religion, denomination, sect and the individual adherent. The Catholic Church considers the death penalty as "inadmissible" in any circumstance and denounces it as an "attack" on the "inviolability and dignity of the person." Both the Baháʼí and Islamic faiths support capital punishment. | [

The sentence ordering that an offender be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being \"on death row\". Etymologically, the term capital (lit. \"of the head\", derived via the Latin capitalis from caput, \"head\") refers to execution by beheading, but executions are carried out by many methods, including hanging, shooting, lethal injection, stoning, electrocution, and gassing.",

Also, in some cases, acts of recidivism, aggravated robbery, and kidnapping, in addition to drug trafficking, drug dealing, and drug possession, are capital crimes or enhancements. However, states have also imposed punitive executions, for an expansive range of conduct, for political or religious beliefs and practices, for a status beyond one's control, or without employing any significant due process procedures.

Blood feuds could be regulated at meetings, such as the Norsemen things.

In the early history of Islam (7th–11th centuries), there is a number of \"purported (but mutually inconsistent) reports\" (athar) regarding the punishments of sodomy ordered by some of the early caliphs. Abu Bakr, the first caliph of the Rashidun Caliphate, apparently recommended toppling a wall on the culprit, or else burning him alive, while Ali ibn Abi Talib is said to have ordered death by stoning for one sodomite and had another thrown head-first from the top of the highest building in the town; according to Ibn Abbas, the latter punishment must be followed by stoning. Other medieval Muslim leaders, such as the Abbasid caliphs in Baghdad (most notably al-Mu'tadid), were often cruel in their punishments. In early modern England, the Buggery Act 1533 stipulated hanging as punishment for \"buggery\". James Pratt and John Smith were the last two Englishmen to be executed for sodomy in 1835. In 1636 the laws of Puritan governed Plymouth Colony included a sentence of death for sodomy and buggery. The Massachusetts Bay Colony followed in 1641. Throughout the 19th century, U.S. states repealed death sentences from their sodomy laws, with South Carolina being the last to do so in 1873.",

"text": "Historians recognise that during the Early Middle Ages, the Christian populations living in the lands invaded by the Arab Muslim armies between the 7th and 10th centuries suffered religious discrimination, religious persecution, religious violence, and martyrdom multiple times at the hands of Arab Muslim officials and rulers. As People of the Book, Christians under Muslim rule were subjected to dhimmi status (along with Jews, Samaritans, Gnostics, Mandeans, and Zoroastrians), which was inferior to the status of Muslims. Christians and other religious minorities thus faced religious discrimination and religious persecution in that they were banned from proselytising (for Christians, it was forbidden to evangelise or spread Christianity) in the lands invaded by the Arab Muslims on pain of death, they were banned from bearing arms, undertaking certain professions, and were obligated to dress differently in order to distinguish themselves from Arabs. Under sharia, Non-Muslims were obligated to pay jizya and kharaj taxes, together with periodic heavy ransom levied upon Christian communities by Muslim rulers in order to fund military campaigns, all of which contributed a significant proportion of income to the Islamic states while conversely reducing many Christians to poverty, and these financial and social hardships forced many Christians to convert to Islam. Christians unable to pay these taxes were forced to surrender their children to the Muslim rulers as payment who would sell them as slaves to Muslim households where they were forced to convert to Islam. Many Christian martyrs were executed under the Islamic death penalty for defending their Christian faith through dramatic acts of resistance such as refusing to convert to Islam, repudiation of the Islamic religion and subsequent reconversion to Christianity, and blasphemy towards Muslim beliefs.",

In England, Jeremy Bentham (1748–1832), the founder of modern utilitarianism, called for the abolition of the death penalty.

Influenced by the book, Grand Duke Leopold II of Habsburg, the future Emperor of Austria, abolished the death penalty in the then-independent Grand Duchy of Tuscany, the first permanent abolition in modern times. On 30 November 1786, after having de facto blocked executions (the last was in 1769), Leopold promulgated the reform of the penal code that abolished the death penalty and ordered the destruction of all the instruments for capital execution in his land. In 2000, Tuscany's regional authorities instituted an annual holiday on 30 November to commemorate the event. The event is commemorated on this day by 300 cities around the world celebrating Cities for Life Day. In the United Kingdom, it was abolished for murder (leaving only treason, piracy with violence, arson in royal dockyards and a number of wartime military offences as capital crimes) for a five-year experiment in 1965 and permanently in 1969, the last execution having taken place in 1964.

Iran accounted for two-thirds of the global total of such executions, and currently has approximately 140 people considered as juveniles awaiting execution for crimes committed (up from 71 in 2007).

] | Capital punishment, also known as the death penalty and formerly called judicial homicide, is the state-sanctioned practice of killing a person as a punishment for a crime, usually following an authorised, rule-governed process to conclude that the person is responsible for violating norms that warrant said punishment. The sentence ordering that an offender be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being "on death row". Etymologically, the term capital refers to execution by beheading, but executions are carried out by many methods, including hanging, shooting, lethal injection, stoning, electrocution, and gassing. Crimes that are punishable by death are known as capital crimes, capital offences, or capital felonies, and vary depending on the jurisdiction, but commonly include serious crimes against a person, such as assassination, mass murder, child murder, aggravated rape, terrorism, aircraft hijacking, war crimes, crimes against humanity, and genocide, along with crimes against the state such as attempting to overthrow government, treason, espionage, sedition, and piracy. Also, in some cases, acts of recidivism, aggravated robbery, and kidnapping, in addition to drug trafficking, drug dealing, and drug possession, are capital crimes or enhancements. However, states have also imposed punitive executions, for an expansive range of conduct, for political or religious beliefs and practices, for a status beyond one's control, or without employing any significant due process procedures. Judicial murder is the intentional and premeditated killing of an innocent person by means of capital punishment. For example, the executions following the show trials in the Soviet Union during the Great Purge of 1936–1938 were an instrument of political repression. As of late 2022, 53 countries retain capital punishment, 111 countries have completely abolished it de jure for all crimes, seven have abolished it for ordinary crimes, and 24 are abolitionist in practice. Although the majority of nations have abolished capital punishment, over 60% of the world's population live in countries where the death penalty is retained, such as China, India, the United States, Singapore, Indonesia, Pakistan, Bangladesh, Nigeria, Egypt, Saudi Arabia, Iran, Japan, and Taiwan. Capital punishment is controversial, with many people, organisations, and religious groups holding differing views on whether it is ethically permissible. Amnesty International declares that the death penalty breaches human rights, specifically "the right to life and the right to live free from torture or cruel, inhuman or degrading treatment or punishment." These rights are protected under the Universal Declaration of Human Rights, adopted by the United Nations in 1948. In the European Union (EU), Article 2 of the Charter of Fundamental Rights of the European Union prohibits the use of capital punishment. The Council of Europe, which has 46 member states, has sought to abolish the use of the death penalty by its members absolutely, through Protocol 13 of the European Convention on Human Rights. However, this only affects those member states which have signed and ratified it, and they do not include Armenia and Azerbaijan. The United Nations General Assembly has adopted, throughout the years from 2007 to 2020, eight non-binding resolutions calling for a global moratorium on executions, with a view to eventual abolition. | 2001-08-18T04:57:41Z | 2023-12-31T11:40:44Z | [

5,905 | Chalcogen | The chalcogens (ore forming) (/ˈkælkədʒənz/ KAL-kə-jənz) are the chemical elements in group 16 of the periodic table. This group is also known as the oxygen family. Group 16 consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). Often, oxygen is treated separately from the other chalcogens, sometimes even excluded from the scope of the term "chalcogen" altogether, due to its very different chemical behavior from sulfur, selenium, tellurium, and polonium. The word "chalcogen" is derived from a combination of the Greek word khalkόs (χαλκός) principally meaning copper (the term was also used for bronze/brass, any metal in the poetic sense, ore or coin), and the Latinized Greek word genēs, meaning born or produced.
Sulfur has been known since antiquity, and oxygen was recognized as an element in the 18th century. Selenium, tellurium and polonium were discovered in the 19th century, and livermorium in 2000. All of the chalcogens have six valence electrons, leaving them two electrons short of a full outer shell. Their most common oxidation states are −2, +2, +4, and +6. They have relatively low atomic radii, especially the lighter ones.
The two lighter chalcogens -- oxygen and sulfur -- are typically nontoxic in their elemental form, and are essential to most life forms, while the heavier chalcogens are typically toxic. All of the naturally occurring chalcogens have some role in biological functions, either as a nutrient or a toxin. Selenium is an important nutrient (among others as a building block of selenocysteine) but is also commonly toxic. Tellurium often has unpleasant effects (although some organisms can use it), and polonium (especially the isotope polonium-210) is always harmful as a result of its radioactivity.
Sulfur has more than 20 allotropes, oxygen has nine, selenium has at least eight, polonium has two, and only one crystal structure of tellurium has so far been discovered. There are numerous organic chalcogen compounds. Not counting oxygen, organic sulfur compounds are generally the most common, followed by organic selenium compounds and organic tellurium compounds. This trend also occurs with chalcogen pnictides and compounds containing chalcogens and carbon group elements.
Oxygen is generally obtained by separation of air into nitrogen and oxygen. Sulfur is extracted from oil and natural gas. Selenium and tellurium are produced as byproducts of copper refining. Polonium is most available in naturally occurring actinide-containing materials. Livermorium has been synthesized in particle accelerators. The primary use of elemental oxygen is in steelmaking. Sulfur is mostly converted into sulfuric acid, which is heavily used in the chemical industry. Selenium's most common application is glassmaking. Tellurium compounds are mostly used in optical disks, electronic devices, and solar cells. Some of polonium's applications are due to its radioactivity.
Chalcogens show similar patterns in electron configuration, especially in the outermost shells, where they all have the same number of valence electrons, resulting in similar trends in chemical behavior:
All chalcogens have six valence electrons. All of the solid, stable chalcogens are soft and do not conduct heat well. Electronegativity decreases towards the chalcogens with higher atomic numbers. Density, melting and boiling points, and atomic and ionic radii tend to increase towards the chalcogens with higher atomic numbers.
Out of the six known chalcogens, one (oxygen) has an atomic number equal to a nuclear magic number, which means that their atomic nuclei tend to have increased stability towards radioactive decay. Oxygen has three stable isotopes, and 14 unstable ones. Sulfur has four stable isotopes, 20 radioactive ones, and one isomer. Selenium has six observationally stable or nearly stable isotopes, 26 radioactive isotopes, and 9 isomers. Tellurium has eight stable or nearly stable isotopes, 31 unstable ones, and 17 isomers. Polonium has 42 isotopes, none of which are stable. It has an additional 28 isomers. In addition to the stable isotopes, some radioactive chalcogen isotopes occur in nature, either because they are decay products, such as Po, because they are primordial, such as Se, because of cosmic ray spallation, or via nuclear fission of uranium. Livermorium isotopes Lv through Lv have been discovered; the most stable livermorium isotope is Lv, which has a half-life of 0.061 seconds.
Among the lighter chalcogens (oxygen and sulfur), the most neutron-poor isotopes undergo proton emission, the moderately neutron-poor isotopes undergo electron capture or β decay, the moderately neutron-rich isotopes undergo β decay, and the most neutron rich isotopes undergo neutron emission. The middle chalcogens (selenium and tellurium) have similar decay tendencies as the lighter chalcogens, but no proton-emitting isotopes have been observed, and some of the most neutron-deficient isotopes of tellurium undergo alpha decay. Polonium isotopes tend to decay via alpha or beta decay. Isotopes with nonzero nuclear spins are more abundant in nature among the chalcogens selenium and tellurium than they are with sulfur.
Oxygen's most common allotrope is diatomic oxygen, or O2, a reactive paramagnetic molecule that is ubiquitous to aerobic organisms and has a blue color in its liquid state. Another allotrope is O3, or ozone, which is three oxygen atoms bonded together in a bent formation. There is also an allotrope called tetraoxygen, or O4, and six allotropes of solid oxygen including "red oxygen", which has the formula O8.
Sulfur has over 20 known allotropes, which is more than any other element except carbon. The most common allotropes are in the form of eight-atom rings, but other molecular allotropes that contain as few as two atoms or as many as 20 are known. Other notable sulfur allotropes include rhombic sulfur and monoclinic sulfur. Rhombic sulfur is the more stable of the two allotropes. Monoclinic sulfur takes the form of long needles and is formed when liquid sulfur is cooled to slightly below its melting point. The atoms in liquid sulfur are generally in the form of long chains, but above 190 °C, the chains begin to break down. If liquid sulfur above 190 °C is frozen very rapidly, the resulting sulfur is amorphous or "plastic" sulfur. Gaseous sulfur is a mixture of diatomic sulfur (S2) and 8-atom rings.
Selenium has at least eight distinct allotropes. The gray allotrope, commonly referred to as the "metallic" allotrope, despite not being a metal, is stable and has a hexagonal crystal structure. The gray allotrope of selenium is soft, with a Mohs hardness of 2, and brittle. Four other allotropes of selenium are metastable. These include two monoclinic red allotropes and two amorphous allotropes, one of which is red and one of which is black. The red allotrope converts to the black allotrope in the presence of heat. The gray allotrope of selenium is made from spirals on selenium atoms, while one of the red allotropes is made of stacks of selenium rings (Se8).
Tellurium is not known to have any allotropes, although its typical form is hexagonal. Polonium has two allotropes, which are known as α-polonium and β-polonium. α-polonium has a cubic crystal structure and converts to the rhombohedral β-polonium at 36 °C.
The chalcogens have varying crystal structures. Oxygen's crystal structure is monoclinic, sulfur's is orthorhombic, selenium and tellurium have the hexagonal crystal structure, while polonium has a cubic crystal structure.
Oxygen, sulfur, and selenium are nonmetals, and tellurium is a metalloid, meaning that its chemical properties are between those of a metal and those of a nonmetal. It is not certain whether polonium is a metal or a metalloid. Some sources refer to polonium as a metalloid, although it has some metallic properties. Also, some allotropes of selenium display characteristics of a metalloid, even though selenium is usually considered a nonmetal. Even though oxygen is a chalcogen, its chemical properties are different from those of other chalcogens. One reason for this is that the heavier chalcogens have vacant d-orbitals. Oxygen's electronegativity is also much higher than those of the other chalcogens. This makes oxygen's electric polarizability several times lower than those of the other chalcogens.
For covalent bonding a chalcogen may accept two electrons according to the octet rule, leaving two lone pairs. When an atom forms two single bonds, they form an angle between 90° and 120°. In 1+ cations, such as H3O, a chalcogen forms three molecular orbitals arranged in a trigonal pyramidal fashion and one lone pair. Double bonds are also common in chalcogen compounds, for example in chalcogenates (see below).
The oxidation number of the most common chalcogen compounds with positive metals is −2. However the tendency for chalcogens to form compounds in the −2 state decreases towards the heavier chalcogens. Other oxidation numbers, such as −1 in pyrite and peroxide, do occur. The highest formal oxidation number is +6. This oxidation number is found in sulfates, selenates, tellurates, polonates, and their corresponding acids, such as sulfuric acid.
Oxygen is the most electronegative element except for fluorine, and forms compounds with almost all of the chemical elements, including some of the noble gases. It commonly bonds with many metals and metalloids to form oxides, including iron oxide, titanium oxide, and silicon oxide. Oxygen's most common oxidation state is −2, and the oxidation state −1 is also relatively common. With hydrogen it forms water and hydrogen peroxide. Organic oxygen compounds are ubiquitous in organic chemistry.
Sulfur's oxidation states are −2, +2, +4, and +6. Sulfur-containing analogs of oxygen compounds often have the prefix thio-. Sulfur's chemistry is similar to oxygen's, in many ways. One difference is that sulfur-sulfur double bonds are far weaker than oxygen-oxygen double bonds, but sulfur-sulfur single bonds are stronger than oxygen-oxygen single bonds. Organic sulfur compounds such as thiols have a strong specific smell, and a few are utilized by some organisms.
Selenium's oxidation states are −2, +4, and +6. Selenium, like most chalcogens, bonds with oxygen. There are some organic selenium compounds, such as selenoproteins. Tellurium's oxidation states are −2, +2, +4, and +6. Tellurium forms the oxides tellurium monoxide, tellurium dioxide, and tellurium trioxide. Polonium's oxidation states are +2 and +4.
There are many acids containing chalcogens, including sulfuric acid, sulfurous acid, selenic acid, and telluric acid. All hydrogen chalcogenides are toxic except for water. Oxygen ions often come in the forms of oxide ions (O), peroxide ions (O2−2), and hydroxide ions (OH). Sulfur ions generally come in the form of sulfides (S), bisulfides (SH), sulfites (SO2−3), sulfates (SO2−4), and thiosulfates (S2O2−3). Selenium ions usually come in the form of selenides (Se), selenites (SeO2−3) and selenates (SeO2−4). Tellurium ions often come in the form of tellurates (TeO2−4). Molecules containing metal bonded to chalcogens are common as minerals. For example, pyrite (FeS2) is an iron ore, and the rare mineral calaverite is the ditelluride (Au, Ag)Te2.
Although all group 16 elements of the periodic table, including oxygen, can be defined as chalcogens, oxygen and oxides are usually distinguished from chalcogens and chalcogenides. The term chalcogenide is more commonly reserved for sulfides, selenides, and tellurides, rather than for oxides.
Except for polonium, the chalcogens are all fairly similar to each other chemically. They all form X ions when reacting with electropositive metals.
Sulfide minerals and analogous compounds produce gases upon reaction with oxygen.
Chalcogens also form compounds with halogens known as chalcohalides, or chalcogen halides. The majority of simple chalcogen halides are well-known and widely used as chemical reagents. However, more complicated chalcogen halides, such as sulfenyl, sulfonyl, and sulfuryl halides, are less well known to science. Out of the compounds consisting purely of chalcogens and halogens, there are a total of 13 chalcogen fluorides, nine chalcogen chlorides, eight chalcogen bromides, and six chalcogen iodides that are known. The heavier chalcogen halides often have significant molecular interactions. Sulfur fluorides with low valences are fairly unstable and little is known about their properties. However, sulfur fluorides with high valences, such as sulfur hexafluoride, are stable and well-known. Sulfur tetrafluoride is also a well-known sulfur fluoride. Certain selenium fluorides, such as selenium difluoride, have been produced in small amounts. The crystal structures of both selenium tetrafluoride and tellurium tetrafluoride are known. Chalcogen chlorides and bromides have also been explored. In particular, selenium dichloride and sulfur dichloride can react to form organic selenium compounds. Dichalcogen dihalides, such as Se2Cl2 also are known to exist. There are also mixed chalcogen-halogen compounds. These include SeSX, with X being chlorine or bromine. Such compounds can form in mixtures of sulfur dichloride and selenium halides. These compounds have been fairly recently structurally characterized, as of 2008. In general, diselenium and disulfur chlorides and bromides are useful chemical reagents. Chalcogen halides with attached metal atoms are soluble in organic solutions. One example of such a compound is MoS2Cl3. Unlike selenium chlorides and bromides, selenium iodides have not been isolated, as of 2008, although it is likely that they occur in solution. Diselenium diiodide, however, does occur in equilibrium with selenium atoms and iodine molecules. Some tellurium halides with low valences, such as Te2Cl2 and Te2Br2, form polymers when in the solid state. These tellurium halides can be synthesized by the reduction of pure tellurium with superhydride and reacting the resulting product with tellurium tetrahalides. Ditellurium dihalides tend to get less stable as the halides become lower in atomic number and atomic mass. Tellurium also forms iodides with even fewer iodine atoms than diiodides. These include TeI and Te2I. These compounds have extended structures in the solid state. Halogens and chalcogens can also form halochalcogenate anions.
Alcohols, phenols and other similar compounds contain oxygen. However, in thiols, selenols and tellurols; sulfur, selenium, and tellurium replace oxygen. Thiols are better known than selenols or tellurols. Aside from alcohols, thiols are the most stable chalcogenols and tellurols are the least stable, being unstable in heat or light. Other organic chalcogen compounds include thioethers, selenoethers and telluroethers. Some of these, such as dimethyl sulfide, diethyl sulfide, and dipropyl sulfide are commercially available. Selenoethers are in the form of R2Se or RSeR. Telluroethers such as dimethyl telluride are typically prepared in the same way as thioethers and selenoethers. Organic chalcogen compounds, especially organic sulfur compounds, have the tendency to smell unpleasant. Dimethyl telluride also smells unpleasant, and selenophenol is renowned for its "metaphysical stench". There are also thioketones, selenoketones, and telluroketones. Out of these, thioketones are the most well-studied with 80% of chalcogenoketones papers being about them. Selenoketones make up 16% of such papers and telluroketones make up 4% of them. Thioketones have well-studied non-linear electric and photophysical properties. Selenoketones are less stable than thioketones and telluroketones are less stable than selenoketones. Telluroketones have the highest level of polarity of chalcogenoketones.
There is a very large number of metal chalcogenides. There are also ternary compounds containing alkali metals and transition metals. Highly metal-rich metal chalcogenides, such as Lu7Te and Lu8Te have domains of the metal's crystal lattice containing chalcogen atoms. While these compounds do exist, analogous chemicals that contain lanthanum, praseodymium, gadolinium, holmium, terbium, or ytterbium have not been discovered, as of 2008. The boron group metals aluminum, gallium, and indium also form bonds to chalcogens. The Ti ion forms chalcogenide dimers such as TiTl5Se8. Metal chalcogenide dimers also occur as lower tellurides, such as Zr5Te6.
Elemental chalcogens react with certain lanthanide compounds to form lanthanide clusters rich in chalcogens. Uranium(IV) chalcogenol compounds also exist. There are also transition metal chalcogenols which have potential to serve as catalysts and stabilize nanoparticles.
Compounds with chalcogen-phosphorus bonds have been explored for more than 200 years. These compounds include unsophisticated phosphorus chalcogenides as well as large molecules with biological roles and phosphorus-chalcogen compounds with metal clusters. These compounds have numerous applications, including organo-phosphate insecticides, strike-anywhere matches and quantum dots. A total of 130,000 compounds with at least one phosphorus-sulfur bond, 6000 compounds with at least one phosphorus-selenium bond, and 350 compounds with at least one phosphorus-tellurium bond have been discovered. The decrease in the number of chalcogen-phosphorus compounds further down the periodic table is due to diminishing bond strength. Such compounds tend to have at least one phosphorus atom in the center, surrounded by four chalcogens and side chains. However, some phosphorus-chalcogen compounds also contain hydrogen (such as secondary phosphine chalcogenides) or nitrogen (such as dichalcogenoimidodiphosphates). Phosphorus selenides are typically harder to handle that phosphorus sulfides, and compounds in the form PxTey have not been discovered. Chalcogens also bond with other pnictogens, such as arsenic, antimony, and bismuth. Heavier chalcogen pnictides tend to form ribbon-like polymers instead of individual molecules. Chemical formulas of these compounds include Bi2S3 and Sb2Se3. Ternary chalcogen pnictides are also known. Examples of these include P4O6Se and P3SbS3. salts containing chalcogens and pnictogens also exist. Almost all chalcogen pnictide salts are typically in the form of [PnxE4x], where Pn is a pnictogen and E is a chalcogen. Tertiary phosphines can react with chalcogens to form compounds in the form of R3PE, where E is a chalcogen. When E is sulfur, these compounds are relatively stable, but they are less so when E is selenium or tellurium. Similarly, secondary phosphines can react with chalcogens to form secondary phosphine chalcogenides. However, these compounds are in a state of equilibrium with chalcogenophosphinous acid. Secondary phosphine chalcogenides are weak acids. Binary compounds consisting of antimony or arsenic and a chalcogen. These compounds tend to be colorful and can be created by a reaction of the constituent elements at temperatures of 500 to 900 °C (932 to 1,652 °F).
Chalcogens form single bonds and double bonds with other carbon group elements than carbon, such as silicon, germanium, and tin. Such compounds typically form from a reaction of carbon group halides and chalcogenol salts or chalcogenol bases. Cyclic compounds with chalcogens, carbon group elements, and boron atoms exist, and occur from the reaction of boron dichalcogenates and carbon group metal halides. Compounds in the form of M-E, where M is silicon, germanium, or tin, and E is sulfur, selenium or tellurium have been discovered. These form when carbon group hydrides react or when heavier versions of carbenes react. Sulfur and tellurium can bond with organic compounds containing both silicon and phosphorus.
All of the chalcogens form hydrides. In some cases this occurs with chalcogens bonding with two hydrogen atoms. However tellurium hydride and polonium hydride are both volatile and highly labile. Also, oxygen can bond to hydrogen in a 1:1 ratio as in hydrogen peroxide, but this compound is unstable.
Chalcogen compounds form a number of interchalcogens. For instance, sulfur forms the toxic sulfur dioxide and sulfur trioxide. Tellurium also forms oxides. There are some chalcogen sulfides as well. These include selenium sulfide, an ingredient in some shampoos.
Since 1990, a number of borides with chalcogens bonded to them have been detected. The chalcogens in these compounds are mostly sulfur, although some do contain selenium instead. One such chalcogen boride consists of two molecules of dimethyl sulfide attached to a boron-hydrogen molecule. Other important boron-chalcogen compounds include macropolyhedral systems. Such compounds tend to feature sulfur as the chalcogen. There are also chalcogen borides with two, three, or four chalcogens. Many of these contain sulfur but some, such as Na2B2Se7 contain selenium instead.
Sulfur has been known since ancient times and is mentioned in the Bible fifteen times. It was known to the ancient Greeks and commonly mined by the ancient Romans. In the Middle Ages, it was a key part of alchemical experiments. In the 1700s and 1800s, scientists Joseph Louis Gay-Lussac and Louis-Jacques Thénard proved sulfur to be a chemical element.
Early attempts to separate oxygen from air were hampered by the fact that air was thought of as a single element up to the 17th and 18th centuries. Robert Hooke, Mikhail Lomonosov, Ole Borch, and Pierre Bayden all successfully created oxygen, but did not realize it at the time. Oxygen was discovered by Joseph Priestley in 1774 when he focused sunlight on a sample of mercuric oxide and collected the resulting gas. Carl Wilhelm Scheele had also created oxygen in 1771 by the same method, but Scheele did not publish his results until 1777.
Tellurium was first discovered in 1783 by Franz Joseph Müller von Reichenstein. He discovered tellurium in a sample of what is now known as calaverite. Müller assumed at first that the sample was pure antimony, but tests he ran on the sample did not agree with this. Muller then guessed that the sample was bismuth sulfide, but tests confirmed that the sample was not that. For some years, Muller pondered the problem. Eventually he realized that the sample was gold bonded with an unknown element. In 1796, Müller sent part of the sample to the German chemist Martin Klaproth, who purified the undiscovered element. Klaproth decided to call the element tellurium after the Latin word for earth.
Selenium was discovered in 1817 by Jöns Jacob Berzelius. Berzelius noticed a reddish-brown sediment at a sulfuric acid manufacturing plant. The sample was thought to contain arsenic. Berzelius initially thought that the sediment contained tellurium, but came to realize that it also contained a new element, which he named selenium after the Greek moon goddess Selene.
Three of the chalcogens (sulfur, selenium, and tellurium) were part of the discovery of periodicity, as they are among a series of triads of elements in the same group that were noted by Johann Wolfgang Döbereiner as having similar properties. Around 1865 John Newlands produced a series of papers where he listed the elements in order of increasing atomic weight and similar physical and chemical properties that recurred at intervals of eight; he likened such periodicity to the octaves of music. His version included a "group b" consisting of oxygen, sulfur, selenium, tellurium, and osmium.
After 1869, Dmitri Mendeleev proposed his periodic table placing oxygen at the top of "group VI" above sulfur, selenium, and tellurium. Chromium, molybdenum, tungsten, and uranium were sometimes included in this group, but they would be later rearranged as part of group VIB; uranium would later be moved to the actinide series. Oxygen, along with sulfur, selenium, tellurium, and later polonium would be grouped in group VIA, until the group's name was changed to group 16 in 1988.
In the late 19th century, Marie Curie and Pierre Curie discovered that a sample of pitchblende was emitting four times as much radioactivity as could be explained by the presence of uranium alone. The Curies gathered several tons of pitchblende and refined it for several months until they had a pure sample of polonium. The discovery officially took place in 1898. Prior to the invention of particle accelerators, the only way to produce polonium was to extract it over several months from uranium ore.
The first attempt at creating livermorium was from 1976 to 1977 at the LBNL, who bombarded curium-248 with calcium-48, but were not successful. After several failed attempts in 1977, 1998, and 1999 by research groups in Russia, Germany, and the US, livermorium was created successfully in 2000 at the Joint Institute for Nuclear Research by bombarding curium-248 atoms with calcium-48 atoms. The element was known as ununhexium until it was officially named livermorium in 2012.
In the 19th century, Jons Jacob Berzelius suggested calling the elements in group 16 "amphigens", as the elements in the group formed amphid salts (salts of oxyacids. Formerly regarded as composed of two oxides, an acid and a basic oxide) The term received some use in the early 1800s but is now obsolete. The name chalcogen comes from the Greek words χαλκος (chalkos, literally "copper"), and γενές (genes, born, gender, kindle). It was first used in 1932 by Wilhelm Biltz's group at Leibniz University Hannover, where it was proposed by Werner Fischer. The word "chalcogen" gained popularity in Germany during the 1930s because the term was analogous to "halogen". Although the literal meanings of the modern Greek words imply that chalcogen means "copper-former", this is misleading because the chalcogens have nothing to do with copper in particular. "Ore-former" has been suggested as a better translation, as the vast majority of metal ores are chalcogenides and the word χαλκος in ancient Greek was associated with metals and metal-bearing rock in general; copper, and its alloy bronze, was one of the first metals to be used by humans.
Oxygen's name comes from the Greek words oxy genes, meaning "acid-forming". Sulfur's name comes from either the Latin word sulfurium or the Sanskrit word sulvere; both of those terms are ancient words for sulfur. Selenium is named after the Greek goddess of the moon, Selene, to match the previously-discovered element tellurium, whose name comes from the Latin word telus, meaning earth. Polonium is named after Marie Curie's country of birth, Poland. Livermorium is named for the Lawrence Livermore National Laboratory.
The four lightest chalcogens (oxygen, sulfur, selenium, and tellurium) are all primordial elements on Earth. Sulfur and oxygen occur as constituent copper ores and selenium and tellurium occur in small traces in such ores. Polonium forms naturally from the decay of other elements, even though it is not primordial. Livermorium does not occur naturally at all.
Oxygen makes up 21% of the atmosphere by weight, 89% of water by weight, 46% of the Earth's crust by weight, and 65% of the human body. Oxygen also occurs in many minerals, being found in all oxide minerals and hydroxide minerals, and in numerous other mineral groups. Stars of at least eight times the mass of the Sun also produce oxygen in their cores via nuclear fusion. Oxygen is the third-most abundant element in the universe, making up 1% of the universe by weight.
Sulfur makes up 0.035% of the Earth's crust by weight, making it the 17th most abundant element there and makes up 0.25% of the human body. It is a major component of soil. Sulfur makes up 870 parts per million of seawater and about 1 part per billion of the atmosphere. Sulfur can be found in elemental form or in the form of sulfide minerals, sulfate minerals, or sulfosalt minerals. Stars of at least 12 times the mass of the Sun produce sulfur in their cores via nuclear fusion. Sulfur is the tenth most abundant element in the universe, making up 500 parts per million of the universe by weight.
Selenium makes up 0.05 parts per million of the Earth's crust by weight. This makes it the 67th most abundant element in the Earth's crust. Selenium makes up on average 5 parts per million of the soils. Seawater contains around 200 parts per trillion of selenium. The atmosphere contains 1 nanogram of selenium per cubic meter. There are mineral groups known as selenates and selenites, but there are not many minerals in these groups. Selenium is not produced directly by nuclear fusion. Selenium makes up 30 parts per billion of the universe by weight.
There are only 5 parts per billion of tellurium in the Earth's crust and 15 parts per billion of tellurium in seawater. Tellurium is one of the eight or nine least abundant elements in the Earth's crust. There are a few dozen tellurate minerals and telluride minerals, and tellurium occurs in some minerals with gold, such as sylvanite and calaverite. Tellurium makes up 9 parts per billion of the universe by weight.
Polonium only occurs in trace amounts on Earth, via radioactive decay of uranium and thorium. It is present in uranium ores in concentrations of 100 micrograms per metric ton. Very minute amounts of polonium exist in the soil and thus in most food, and thus in the human body. The Earth's crust contains less than 1 part per billion of polonium, making it one of the ten rarest metals on Earth.
Livermorium is always produced artificially in particle accelerators. Even when it is produced, only a small number of atoms are synthesized at a time.
Chalcophile elements are those that remain on or close to the surface because they combine readily with chalcogens other than oxygen, forming compounds which do not sink into the core. Chalcophile ("chalcogen-loving") elements in this context are those metals and heavier nonmetals that have a low affinity for oxygen and prefer to bond with the heavier chalcogen sulfur as sulfides. Because sulfide minerals are much denser than the silicate minerals formed by lithophile elements, chalcophile elements separated below the lithophiles at the time of the first crystallisation of the Earth's crust. This has led to their depletion in the Earth's crust relative to their solar abundances, though this depletion has not reached the levels found with siderophile elements.

Approximately 100 million metric tons of oxygen are produced yearly. Oxygen is most commonly produced by fractional distillation, in which air is cooled to a liquid, then warmed, allowing all the components of air except for oxygen to turn to gases and escape. Fractionally distilling air several times can produce 99.5% pure oxygen. Another method with which oxygen is produced is to send a stream of dry, clean air through a bed of molecular sieves made of zeolite, which absorbs the nitrogen in the air, leaving 90 to 93% pure oxygen.
Sulfur can be mined in its elemental form, although this method is no longer as popular as it used to be. In 1865 a large deposit of elemental sulfur was discovered in the U.S. states of Louisiana and Texas, but it was difficult to extract at the time. In the 1890s, Herman Frasch came up with the solution of liquefying the sulfur with superheated steam and pumping the sulfur up to the surface. These days sulfur is instead more often extracted from oil, natural gas, and tar.
The world production of selenium is around 1500 metric tons per year, out of which roughly 10% is recycled. Japan is the largest producer, producing 800 metric tons of selenium per year. Other large producers include Belgium (300 metric tons per year), the United States (over 200 metric tons per year), Sweden (130 metric tons per year), and Russia (100 metric tons per year). Selenium can be extracted from the waste from the process of electrolytically refining copper. Another method of producing selenium is to farm selenium-gathering plants such as milk vetch. This method could produce three kilograms of selenium per acre, but is not commonly practiced.
Tellurium is mostly produced as a by-product of the processing of copper. Tellurium can also be refined by electrolytic reduction of sodium telluride. The world production of tellurium is between 150 and 200 metric tons per year. The United States is one of the largest producers of tellurium, producing around 50 metric tons per year. Peru, Japan, and Canada are also large producers of tellurium.
Until the creation of nuclear reactors, all polonium had to be extracted from uranium ore. In modern times, most isotopes of polonium are produced by bombarding bismuth with neutrons. Polonium can also be produced by high neutron fluxes in nuclear reactors. Approximately 100 grams of polonium are produced yearly. All the polonium produced for commercial purposes is made in the Ozersk nuclear reactor in Russia. From there, it is taken to Samara, Russia for purification, and from there to St. Petersburg for distribution. The United States is the largest consumer of polonium.
All livermorium is produced artificially in particle accelerators. The first successful production of livermorium was achieved by bombarding curium-248 atoms with calcium-48 atoms. As of 2011, roughly 25 atoms of livermorium had been synthesized.
Metabolism is the most important source and use of oxygen. Minor industrial uses include Steelmaking (55% of all purified oxygen produced), the chemical industry (25% of all purified oxygen), medical use, water treatment (as oxygen kills some types of bacteria), rocket fuel (in liquid form), and metal cutting.
Most sulfur produced is transformed into sulfur dioxide, which is further transformed into sulfuric acid, a very common industrial chemical. Other common uses include being a key ingredient of gunpowder and Greek fire, and being used to change soil pH. Sulfur is also mixed into rubber to vulcanize it. Sulfur is used in some types of concrete and fireworks. 60% of all sulfuric acid produced is used to generate phosphoric acid. Sulfur is used as a pesticide (specifically as an acaricide and fungicide) on "orchard, ornamental, vegetable, grain, and other crops."
Around 40% of all selenium produced goes to glassmaking. 30% of all selenium produced goes to metallurgy, including manganese production. 15% of all selenium produced goes to agriculture. Electronics such as photovoltaic materials claim 10% of all selenium produced. Pigments account for 5% of all selenium produced. Historically, machines such as photocopiers and light meters used one-third of all selenium produced, but this application is in steady decline.
Tellurium suboxide, a mixture of tellurium and tellurium dioxide, is used in the rewritable data layer of some CD-RW disks and DVD-RW disks. Bismuth telluride is also used in many microelectronic devices, such as photoreceptors. Tellurium is sometimes used as an alternative to sulfur in vulcanized rubber. Cadmium telluride is used as a high-efficiency material in solar panels.
Some of polonium's applications relate to the element's radioactivity. For instance, polonium is used as an alpha-particle generator for research. Polonium alloyed with beryllium provides an efficient neutron source. Polonium is also used in nuclear batteries. Most polonium is used in antistatic devices. Livermorium does not have any uses whatsoever due to its extreme rarity and short half-life.
Organochalcogen compounds are involved in the semiconductor process. These compounds also feature into ligand chemistry and biochemistry. One application of chalcogens themselves is to manipulate redox couples in supramolecular chemistry (chemistry involving non-covalent bond interactions). This application leads on to such applications as crystal packing, assembly of large molecules, and biological recognition of patterns. The secondary bonding interactions of the larger chalcogens, selenium and tellurium, can create organic solvent-holding acetylene nanotubes. Chalcogen interactions are useful for conformational analysis and stereoelectronic effects, among other things. Chalcogenides with through bonds also have applications. For instance, divalent sulfur can stabilize carbanions, cationic centers, and radical. Chalcogens can confer upon ligands (such as DCTO) properties such as being able to transform Cu(II) to Cu(I). Studying chalcogen interactions gives access to radical cations, which are used in mainstream synthetic chemistry. Metallic redox centers of biological importance are tunable by interactions of ligands containing chalcogens, such as methionine and selenocysteine. Also, chalcogen through-bonds can provide insight about the process of electron transfer.
Oxygen is needed by almost all organisms for the purpose of generating ATP. It is also a key component of most other biological compounds, such as water, amino acids and DNA. Human blood contains a large amount of oxygen. Human bones contain 28% oxygen. Human tissue contains 16% oxygen. A typical 70-kilogram human contains 43 kilograms of oxygen, mostly in the form of water.
All animals need significant amounts of sulfur. Some amino acids, such as cysteine and methionine contain sulfur. Plant roots take up sulfate ions from the soil and reduce it to sulfide ions. Metalloproteins also use sulfur to attach to useful metal atoms in the body and sulfur similarly attaches itself to poisonous metal atoms like cadmium to haul them to the safety of the liver. On average, humans consume 900 milligrams of sulfur each day. Sulfur compounds, such as those found in skunk spray often have strong odors.
All animals and some plants need trace amounts of selenium, but only for some specialized enzymes. Humans consume on average between 6 and 200 micrograms of selenium per day. Mushrooms and brazil nuts are especially noted for their high selenium content. Selenium in foods is most commonly found in the form of amino acids such as selenocysteine and selenomethionine. Selenium can protect against heavy metal poisoning.
Tellurium is not known to be needed for animal life, although a few fungi can incorporate it in compounds in place of selenium. Microorganisms also absorb tellurium and emit dimethyl telluride. Most tellurium in the blood stream is excreted slowly in urine, but some is converted to dimethyl telluride and released through the lungs. On average, humans ingest about 600 micrograms of tellurium daily. Plants can take up some tellurium from the soil. Onions and garlic have been found to contain as much as 300 parts per million of tellurium in dry weight.
Polonium has no biological role, and is highly toxic on account of being radioactive.
Oxygen is generally nontoxic, but oxygen toxicity has been reported when it is used in high concentrations. In both elemental gaseous form and as a component of water, it is vital to almost all life on Earth. Despite this, liquid oxygen is highly dangerous. Even gaseous oxygen is dangerous in excess. For instance, sports divers have occasionally drowned from convulsions caused by breathing pure oxygen at a depth of more than 10 meters (33 feet) underwater. Oxygen is also toxic to some bacteria. Ozone, an allotrope of oxygen, is toxic to most life. It can cause lesions in the respiratory tract.
Sulfur is generally nontoxic and is even a vital nutrient for humans. However, in its elemental form it can cause redness in the eyes and skin, a burning sensation and a cough if inhaled, a burning sensation and diarrhoea and/or catharsis if ingested, and can irritate the mucous membranes. An excess of sulfur can be toxic for cows because microbes in the rumens of cows produce toxic hydrogen sulfide upon reaction with sulfur. Many sulfur compounds, such as hydrogen sulfide (H2S) and sulfur dioxide (SO2) are highly toxic.
Selenium is a trace nutrient required by humans on the order of tens or hundreds of micrograms per day. A dose of over 450 micrograms can be toxic, resulting in bad breath and body odor. Extended, low-level exposure, which can occur at some industries, results in weight loss, anemia, and dermatitis. In many cases of selenium poisoning, selenous acid is formed in the body. Hydrogen selenide (H2Se) is highly toxic.
Exposure to tellurium can produce unpleasant side effects. As little as 10 micrograms of tellurium per cubic meter of air can cause notoriously unpleasant breath, described as smelling like rotten garlic. Acute tellurium poisoning can cause vomiting, gut inflammation, internal bleeding, and respiratory failure. Extended, low-level exposure to tellurium causes tiredness and indigestion. Sodium tellurite (Na2TeO3) is lethal in amounts of around 2 grams.
Polonium is dangerous as an alpha particle emitter. If ingested, polonium-210 is a million times as toxic as hydrogen cyanide by weight; it has been used as a murder weapon in the past, most famously to kill Alexander Litvinenko. Polonium poisoning can cause nausea, vomiting, anorexia, and lymphopenia. It can also damage hair follicles and white blood cells. Polonium-210 is only dangerous if ingested or inhaled because its alpha particle emissions cannot penetrate human skin. Polonium-209 is also toxic, and can cause leukemia.
Amphid salts was a name given by Jons Jacob Berzelius in the 19th century for chemical salts derived from the 16th group of the periodic table which included oxygen, sulfur, selenium, and tellurium. The term received some use in the early 1800s but is now obsolete. The current term in use for the 16th group is chalcogens. | [

Group 16 consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). Often, oxygen is treated separately from the other chalcogens, sometimes even excluded from the scope of the term \"chalcogen\" altogether, due to its very different chemical behavior from sulfur, selenium, tellurium, and polonium. The word \"chalcogen\" is derived from a combination of the Greek word khalkόs (χαλκός) principally meaning copper (the term was also used for bronze/brass, any metal in the poetic sense, ore or coin), and the Latinized Greek word genēs, meaning born or produced.",

Dichalcogen dihalides, such as Se2Cl2 also are known to exist. There are also mixed chalcogen-halogen compounds. These include SeSX, with X being chlorine or bromine. Such compounds can form in mixtures of sulfur dichloride and selenium halides. These compounds have been fairly recently structurally characterized, as of 2008. In general, diselenium and disulfur chlorides and bromides are useful chemical reagents. Chalcogen halides with attached metal atoms are soluble in organic solutions. One example of such a compound is MoS2Cl3. Unlike selenium chlorides and bromides, selenium iodides have not been isolated, as of 2008, although it is likely that they occur in solution. Diselenium diiodide, however, does occur in equilibrium with selenium atoms and iodine molecules. Some tellurium halides with low valences, such as Te2Cl2 and Te2Br2, form polymers when in the solid state. These tellurium halides can be synthesized by the reduction of pure tellurium with superhydride and reacting the resulting product with tellurium tetrahalides. Ditellurium dihalides tend to get less stable as the halides become lower in atomic number and atomic mass. Tellurium also forms iodides with even fewer iodine atoms than diiodides. These include TeI and Te2I. These compounds have extended structures in the solid state. Halogens and chalcogens can also form halochalcogenate anions.",

] | The chalcogens are the chemical elements in group 16 of the periodic table. This group is also known as the oxygen family. Group 16 consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). Often, oxygen is treated separately from the other chalcogens, sometimes even excluded from the scope of the term "chalcogen" altogether, due to its very different chemical behavior from sulfur, selenium, tellurium, and polonium. The word "chalcogen" is derived from a combination of the Greek word khalkόs (χαλκός) principally meaning copper, and the Latinized Greek word genēs, meaning born or produced. Sulfur has been known since antiquity, and oxygen was recognized as an element in the 18th century. Selenium, tellurium and polonium were discovered in the 19th century, and livermorium in 2000. All of the chalcogens have six valence electrons, leaving them two electrons short of a full outer shell. Their most common oxidation states are −2, +2, +4, and +6. They have relatively low atomic radii, especially the lighter ones. The two lighter chalcogens -- oxygen and sulfur -- are typically nontoxic in their elemental form, and are essential to most life forms, while the heavier chalcogens are typically toxic. All of the naturally occurring chalcogens have some role in biological functions, either as a nutrient or a toxin. Selenium is an important nutrient but is also commonly toxic. Tellurium often has unpleasant effects, and polonium is always harmful as a result of its radioactivity. Sulfur has more than 20 allotropes, oxygen has nine, selenium has at least eight, polonium has two, and only one crystal structure of tellurium has so far been discovered. There are numerous organic chalcogen compounds. Not counting oxygen, organic sulfur compounds are generally the most common, followed by organic selenium compounds and organic tellurium compounds. This trend also occurs with chalcogen pnictides and compounds containing chalcogens and carbon group elements. Oxygen is generally obtained by separation of air into nitrogen and oxygen. Sulfur is extracted from oil and natural gas. Selenium and tellurium are produced as byproducts of copper refining. Polonium is most available in naturally occurring actinide-containing materials. Livermorium has been synthesized in particle accelerators. The primary use of elemental oxygen is in steelmaking. Sulfur is mostly converted into sulfuric acid, which is heavily used in the chemical industry. Selenium's most common application is glassmaking. Tellurium compounds are mostly used in optical disks, electronic devices, and solar cells. Some of polonium's applications are due to its radioactivity. | 2001-07-26T23:08:56Z | 2023-12-26T16:04:31Z | [

5,906 | Carbon dioxide | Carbon dioxide is a chemical compound with the chemical formula CO2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. When carbon dioxide dissolves in water, it forms carbonate and mainly bicarbonate (HCO−3), which causes ocean acidification as atmospheric CO2 levels increase.
It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% (as of May 2022) having risen from pre-industrial levels of 280 ppm or about 0.025%. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.
Its concentration in Earth's pre-industrial atmosphere since late in the Precambrian was regulated by organisms and geological phenomena. Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product. In turn, oxygen is consumed and CO2 is released as waste by all aerobic organisms when they metabolize organic compounds to produce energy by respiration. CO2 is released from organic materials when they decay or combust, such as in forest fires. Since plants require CO2 for photosynthesis, and humans and animals depend on plants for food, CO2 is necessary for the survival of life on earth.
Carbon dioxide is 53% more dense than dry air, but is long lived and thoroughly mixes in the atmosphere. About half of excess CO2 emissions to the atmosphere are absorbed by land and ocean carbon sinks. These sinks can become saturated and are volatile, as decay and wildfires result in the CO2 being released back into the atmosphere. CO2 is eventually sequestered (stored for the long term) in rocks and organic deposits like coal, petroleum and natural gas. Sequestered CO2 is released into the atmosphere through burning fossil fuels or naturally by volcanoes, hot springs, geysers, and when carbonate rocks dissolve in water or react with acids.
CO2 is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, and as a supercritical fluid solvent in decaffeination of coffee and supercritical drying. It is a byproduct of fermentation of sugars in bread, beer and wine making, and is added to carbonated beverages like seltzer and beer for effervescence. It has a sharp and acidic odor and generates the taste of soda water in the mouth, but at normally encountered concentrations it is odorless.
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon-oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140-pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls. Since it is centrosymmetric, the molecule has no electric dipole moment.
As a linear triatomic molecule, CO2 has four vibrational modes as shown in the diagram. In the symmetric and the antisymmetric stretching modes, the atoms move along the axis of the molecule. There are two bending modes, which are degenerate, meaning that they have the same frequency and same energy, because of the symmetry of the molecule. When a molecule touches a surface or touches another molecule, the two bending modes can differ in frequency because the interaction is different for the two modes. Some of the vibrational modes are observed in the infrared (IR) spectrum: the antisymmetric stretching mode at wavenumber 2349 cm (wavelength 4.25 μm) and the degenerate pair of bending modes at 667 cm (wavelength 15 μm). The symmetric stretching mode does not create an electric dipole so is not observed in IR spectroscopy, but it is detected in by Raman spectroscopy at 1388 cm (wavelength 7.2 μm).
In the gas phase, carbon dioxide molecules undergo significant vibrational motions and do not keep a fixed structure. However, in a Coulomb explosion imaging experiment, an instantaneous image of the molecular structure can be deduced. Such an experiment has been performed for carbon dioxide. The result of this experiment, and the conclusion of theoretical calculations based on an ab initio potential energy surface of the molecule, is that none of the molecules in the gas phase are ever exactly linear. This counter-intuitive result is trivially due to the fact that the nuclear motion volume element vanishes for linear geometries. This is so for all molecules (except diatomics!).
Carbon dioxide is soluble in water, in which it reversibly forms H2CO3 (carbonic acid), which is a weak acid since its ionization in water is incomplete.
The hydration equilibrium constant of carbonic acid is, at 25 °C:
Hence, the majority of the carbon dioxide is not converted into carbonic acid, but remains as CO2 molecules, not affecting the pH.
The relative concentrations of CO2, H2CO3, and the deprotonated forms HCO−3 (bicarbonate) and CO2−3(carbonate) depend on the pH. As shown in a Bjerrum plot, in neutral or slightly alkaline water (pH > 6.5), the bicarbonate form predominates (>50%) becoming the most prevalent (>95%) at the pH of seawater. In very alkaline water (pH > 10.4), the predominant (>50%) form is carbonate. The oceans, being mildly alkaline with typical pH = 8.2–8.5, contain about 120 mg of bicarbonate per liter.
Being diprotic, carbonic acid has two acid dissociation constants, the first one for the dissociation into the bicarbonate (also called hydrogen carbonate) ion (HCO−3):
This is the true first acid dissociation constant, defined as
where the denominator includes only covalently bound H2CO3 and does not include hydrated CO2(aq). The much smaller and often-quoted value near 4.16 × 10 is an apparent value calculated on the (incorrect) assumption that all dissolved CO2 is present as carbonic acid, so that
Since most of the dissolved CO2 remains as CO2 molecules, Ka1(apparent) has a much larger denominator and a much smaller value than the true Ka1.
The bicarbonate ion is an amphoteric species that can act as an acid or as a base, depending on pH of the solution. At high pH, it dissociates significantly into the carbonate ion (CO2−3):
In organisms, carbonic acid production is catalysed by the enzyme known as carbonic anhydrase.
CO2 is a potent electrophile having an electrophilic reactivity that is comparable to benzaldehyde or strong α,β-unsaturated carbonyl compounds. However, unlike electrophiles of similar reactivity, the reactions of nucleophiles with CO2 are thermodynamically less favored and are often found to be highly reversible. The reversible reaction of carbon dioxide with amines to make carbamates is used in CO2 scrubbers and has been suggested as a possible starting point for carbon capture and storage by amine gas treating. Only very strong nucleophiles, like the carbanions provided by Grignard reagents and organolithium compounds react with CO2 to give carboxylates:
In metal carbon dioxide complexes, CO2 serves as a ligand, which can facilitate the conversion of CO2 to other chemicals.
The reduction of CO2 to CO is ordinarily a difficult and slow reaction:
Photoautotrophs (i.e. plants and cyanobacteria) use the energy contained in sunlight to photosynthesize simple sugars from CO2 absorbed from the air and water:
The redox potential for this reaction near pH 7 is about −0.53 V versus the standard hydrogen electrode. The nickel-containing enzyme carbon monoxide dehydrogenase catalyses this process.
Carbon dioxide is colorless. At low concentrations, the gas is odorless; however, at sufficiently high concentrations, it has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m, about 1.53 times that of air.
Carbon dioxide has no liquid state at pressures below 0.51795(10) MPa (5.11177(99) atm). At a pressure of 1 atm (0.101325 MPa), the gas deposits directly to a solid at temperatures below 194.6855(30) K (−78.4645(30) °C) and the solid sublimes directly to a gas above this temperature. In its solid state, carbon dioxide is commonly called dry ice.
Liquid carbon dioxide forms only at pressures above 0.51795(10) MPa (5.11177(99) atm); the triple point of carbon dioxide is 216.592(3) K (−56.558(3) °C) at 0.51795(10) MPa (5.11177(99) atm) (see phase diagram). The critical point is 304.128(15) K (30.978(15) °C) at 7.3773(30) MPa (72.808(30) atm). Another form of solid carbon dioxide observed at high pressure is an amorphous glass-like solid. This form of glass, called carbonia, is produced by supercooling heated CO2 at extreme pressures (40–48 GPa, or about 400,000 atmospheres) in a diamond anvil. This discovery confirmed the theory that carbon dioxide could exist in a glass state similar to other members of its elemental family, like silicon dioxide (silica glass) and germanium dioxide. Unlike silica and germania glasses, however, carbonia glass is not stable at normal pressures and reverts to gas when pressure is released.
At temperatures and pressures above the critical point, carbon dioxide behaves as a supercritical fluid known as supercritical carbon dioxide.

Table of thermal and physical properties of carbon dioxide (CO2) at atmospheric pressure:
Carbon dioxide is an end product of cellular respiration in organisms that obtain energy by breaking down sugars, fats and amino acids with oxygen as part of their metabolism. This includes all plants, algae and animals and aerobic fungi and bacteria. In vertebrates, the carbon dioxide travels in the blood from the body's tissues to the skin (e.g., amphibians) or the gills (e.g., fish), from where it dissolves in the water, or to the lungs from where it is exhaled. During active photosynthesis, plants can absorb more carbon dioxide from the atmosphere than they release in respiration.
Carbon fixation is a biochemical process by which atmospheric carbon dioxide is incorporated by plants, algae and (cyanobacteria) into energy-rich organic molecules such as glucose, thus creating their own food by photosynthesis. Photosynthesis uses carbon dioxide and water to produce sugars from which other organic compounds can be constructed, and oxygen is produced as a by-product.
Ribulose-1,5-bisphosphate carboxylase oxygenase, commonly abbreviated to RuBisCO, is the enzyme involved in the first major step of carbon fixation, the production of two molecules of 3-phosphoglycerate from CO2 and ribulose bisphosphate, as shown in the diagram at left.
RuBisCO is thought to be the single most abundant protein on Earth.
Phototrophs use the products of their photosynthesis as internal food sources and as raw material for the biosynthesis of more complex organic molecules, such as polysaccharides, nucleic acids, and proteins. These are used for their own growth, and also as the basis of the food chains and webs that feed other organisms, including animals such as ourselves. Some important phototrophs, the coccolithophores synthesise hard calcium carbonate scales. A globally significant species of coccolithophore is Emiliania huxleyi whose calcite scales have formed the basis of many sedimentary rocks such as limestone, where what was previously atmospheric carbon can remain fixed for geological timescales.
Plants can grow as much as 50% faster in concentrations of 1,000 ppm CO2 when compared with ambient conditions, though this assumes no change in climate and no limitation on other nutrients. Elevated CO2 levels cause increased growth reflected in the harvestable yield of crops, with wheat, rice and soybean all showing increases in yield of 12–14% under elevated CO2 in FACE experiments.
Increased atmospheric CO2 concentrations result in fewer stomata developing on plants which leads to reduced water usage and increased water-use efficiency. Studies using FACE have shown that CO2 enrichment leads to decreased concentrations of micronutrients in crop plants. This may have knock-on effects on other parts of ecosystems as herbivores will need to eat more food to gain the same amount of protein.
The concentration of secondary metabolites such as phenylpropanoids and flavonoids can also be altered in plants exposed to high concentrations of CO2.
Plants also emit CO2 during respiration, and so the majority of plants and algae, which use C3 photosynthesis, are only net absorbers during the day. Though a growing forest will absorb many tons of CO2 each year, a mature forest will produce as much CO2 from respiration and decomposition of dead specimens (e.g., fallen branches) as is used in photosynthesis in growing plants. Contrary to the long-standing view that they are carbon neutral, mature forests can continue to accumulate carbon and remain valuable carbon sinks, helping to maintain the carbon balance of Earth's atmosphere. Additionally, and crucially to life on earth, photosynthesis by phytoplankton consumes dissolved CO2 in the upper ocean and thereby promotes the absorption of CO2 from the atmosphere.
Carbon dioxide content in fresh air (averaged between sea-level and 10 kPa level, i.e., about 30 km (19 mi) altitude) varies between 0.036% (360 ppm) and 0.041% (412 ppm), depending on the location.
CO2 is an asphyxiant gas and not classified as toxic or harmful in accordance with Globally Harmonized System of Classification and Labelling of Chemicals standards of United Nations Economic Commission for Europe by using the OECD Guidelines for the Testing of Chemicals. In concentrations up to 1% (10,000 ppm), it will make some people feel drowsy and give the lungs a stuffy feeling. Concentrations of 7% to 10% (70,000 to 100,000 ppm) may cause suffocation, even in the presence of sufficient oxygen, manifesting as dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour. The physiological effects of acute carbon dioxide exposure are grouped together under the term hypercapnia, a subset of asphyxiation.
Because it is heavier than air, in locations where the gas seeps from the ground (due to sub-surface volcanic or geothermal activity) in relatively high concentrations, without the dispersing effects of wind, it can collect in sheltered/pocketed locations below average ground level, causing animals located therein to be suffocated. Carrion feeders attracted to the carcasses are then also killed. Children have been killed in the same way near the city of Goma by CO2 emissions from the nearby volcano Mount Nyiragongo. The Swahili term for this phenomenon is mazuku.
Adaptation to increased concentrations of CO2 occurs in humans, including modified breathing and kidney bicarbonate production, in order to balance the effects of blood acidification (acidosis). Several studies suggested that 2.0 percent inspired concentrations could be used for closed air spaces (e.g. a submarine) since the adaptation is physiological and reversible, as deterioration in performance or in normal physical activity does not happen at this level of exposure for five days. Yet, other studies show a decrease in cognitive function even at much lower levels. Also, with ongoing respiratory acidosis, adaptation or compensatory mechanisms will be unable to reverse such condition.
There are few studies of the health effects of long-term continuous CO2 exposure on humans and animals at levels below 1%. Occupational CO2 exposure limits have been set in the United States at 0.5% (5000 ppm) for an eight-hour period. At this CO2 concentration, International Space Station crew experienced headaches, lethargy, mental slowness, emotional irritation, and sleep disruption. Studies in animals at 0.5% CO2 have demonstrated kidney calcification and bone loss after eight weeks of exposure. A study of humans exposed in 2.5 hour sessions demonstrated significant negative effects on cognitive abilities at concentrations as low as 0.1% (1000 ppm) CO2 likely due to CO2 induced increases in cerebral blood flow. Another study observed a decline in basic activity level and information usage at 1000 ppm, when compared to 500 ppm.
However a review of the literature found that a reliable subset of studies on the phenomenon of carbon dioxide induced cognitive impairment to only show a small effect on high-level decision making (for concentrations below 5000 ppm). Most of the studies were confounded by inadequate study designs, environmental comfort, uncertainties in exposure doses and differing cognitive assessments used. Similarly a study on the effects of the concentration of CO2 in motorcycle helmets has been criticized for having dubious methodology in not noting the self-reports of motorcycle riders and taking measurements using mannequins. Further when normal motorcycle conditions were achieved (such as highway or city speeds) or the visor was raised the concentration of CO2 declined to safe levels (0.2%).
Poor ventilation is one of the main causes of excessive CO2 concentrations in closed spaces, leading to poor indoor air quality. Carbon dioxide differential above outdoor concentrations at steady state conditions (when the occupancy and ventilation system operation are sufficiently long that CO2 concentration has stabilized) are sometimes used to estimate ventilation rates per person. Higher CO2 concentrations are associated with occupant health, comfort and performance degradation. ASHRAE Standard 62.1–2007 ventilation rates may result in indoor concentrations up to 2,100 ppm above ambient outdoor conditions. Thus if the outdoor concentration is 400 ppm, indoor concentrations may reach 2,500 ppm with ventilation rates that meet this industry consensus standard. Concentrations in poorly ventilated spaces can be found even higher than this (range of 3,000 or 4,000 ppm).
Miners, who are particularly vulnerable to gas exposure due to insufficient ventilation, referred to mixtures of carbon dioxide and nitrogen as "blackdamp", "choke damp" or "stythe". Before more effective technologies were developed, miners would frequently monitor for dangerous levels of blackdamp and other gases in mine shafts by bringing a caged canary with them as they worked. The canary is more sensitive to asphyxiant gases than humans, and as it became unconscious would stop singing and fall off its perch. The Davy lamp could also detect high levels of blackdamp (which sinks, and collects near the floor) by burning less brightly, while methane, another suffocating gas and explosion risk, would make the lamp burn more brightly.
In February 2020, three people died from suffocation at a party in Moscow when dry ice (frozen CO2) was added to a swimming pool to cool it down. A similar accident occurred in 2018 when a woman died from CO2 fumes emanating from the large amount of dry ice she was transporting in her car.
Humans spend more and more time in a confined atmosphere (around 80-90% of the time in a building or vehicle). According to the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) and various actors in France, the CO2 rate in the indoor air of buildings (linked to human or animal occupancy and the presence of combustion installations), weighted by air renewal, is “usually between about 350 and 2,500 ppm”.
In homes, schools, nurseries and offices, there are no systematic relationships between the levels of CO2 and other pollutants, and indoor CO2 is statistically not a good predictor of pollutants linked to outdoor road (or air, etc.) traffic. CO2 is the parameter that changes the fastest (with hygrometry and oxygen levels when humans or animals are gathered in a closed or poorly ventilated room). In poor countries, many open hearths are sources of CO2 and CO emitted directly into the living environment.
Local concentrations of carbon dioxide can reach high values near strong sources, especially those that are isolated by surrounding terrain. At the Bossoleto hot spring near Rapolano Terme in Tuscany, Italy, situated in a bowl-shaped depression about 100 m (330 ft) in diameter, concentrations of CO2 rise to above 75% overnight, sufficient to kill insects and small animals. After sunrise the gas is dispersed by convection. High concentrations of CO2 produced by disturbance of deep lake water saturated with CO2 are thought to have caused 37 fatalities at Lake Monoun, Cameroon in 1984 and 1700 casualties at Lake Nyos, Cameroon in 1986.
The body produces approximately 2.3 pounds (1.0 kg) of carbon dioxide per day per person, containing 0.63 pounds (290 g) of carbon. In humans, this carbon dioxide is carried through the venous system and is breathed out through the lungs, resulting in lower concentrations in the arteries. The carbon dioxide content of the blood is often given as the partial pressure, which is the pressure which carbon dioxide would have had if it alone occupied the volume. In humans, the blood carbon dioxide contents is shown in the adjacent table.
CO2 is carried in blood in three different ways. (Exact percentages vary between arterial and venous blood).
Hemoglobin, the main oxygen-carrying molecule in red blood cells, carries both oxygen and carbon dioxide. However, the CO2 bound to hemoglobin does not bind to the same site as oxygen. Instead, it combines with the N-terminal groups on the four globin chains. However, because of allosteric effects on the hemoglobin molecule, the binding of CO2 decreases the amount of oxygen that is bound for a given partial pressure of oxygen. This is known as the Haldane Effect, and is important in the transport of carbon dioxide from the tissues to the lungs. Conversely, a rise in the partial pressure of CO2 or a lower pH will cause offloading of oxygen from hemoglobin, which is known as the Bohr effect.
Carbon dioxide is one of the mediators of local autoregulation of blood supply. If its concentration is high, the capillaries expand to allow a greater blood flow to that tissue.
Bicarbonate ions are crucial for regulating blood pH. A person's breathing rate influences the level of CO2 in their blood. Breathing that is too slow or shallow causes respiratory acidosis, while breathing that is too rapid leads to hyperventilation, which can cause respiratory alkalosis.
Although the body requires oxygen for metabolism, low oxygen levels normally do not stimulate breathing. Rather, breathing is stimulated by higher carbon dioxide levels. As a result, breathing low-pressure air or a gas mixture with no oxygen at all (such as pure nitrogen) can lead to loss of consciousness without ever experiencing air hunger. This is especially perilous for high-altitude fighter pilots. It is also why flight attendants instruct passengers, in case of loss of cabin pressure, to apply the oxygen mask to themselves first before helping others; otherwise, one risks losing consciousness.
The respiratory centers try to maintain an arterial CO2 pressure of 40 mmHg. With intentional hyperventilation, the CO2 content of arterial blood may be lowered to 10–20 mmHg (the oxygen content of the blood is little affected), and the respiratory drive is diminished. This is why one can hold one's breath longer after hyperventilating than without hyperventilating. This carries the risk that unconsciousness may result before the need to breathe becomes overwhelming, which is why hyperventilation is particularly dangerous before free diving.
In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of several greenhouse gases in the atmosphere of Earth. The current global average concentration of CO2 in the atmosphere is 421 ppm as of May 2022 (0.04%). This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. The increase is due to human activity. Burning fossil fuels is the main cause of these increased CO2 concentrations and also the main cause of climate change. Other large anthropogenic sources include cement production, deforestation, and biomass burning.
While transparent to visible light, carbon dioxide is a greenhouse gas, absorbing and emitting infrared radiation at its two infrared-active vibrational frequencies. CO2 absorbs and emits infrared radiation at wavelengths of 4.26 μm (2,347 cm) (asymmetric stretching vibrational mode) and 14.99 μm (667 cm) (bending vibrational mode). It plays a significant role in influencing Earth's surface temperature through the greenhouse effect. Light emission from the Earth's surface is most intense in the infrared region between 200 and 2500 cm, as opposed to light emission from the much hotter Sun which is most intense in the visible region. Absorption of infrared light at the vibrational frequencies of atmospheric CO2 traps energy near the surface, warming the surface and the lower atmosphere. Less energy reaches the upper atmosphere, which is therefore cooler because of this absorption.
Increases in atmospheric concentrations of CO2 and other long-lived greenhouse gases such as methane, nitrous oxide and ozone increase the absorption and emission of infrared radiation by the atmosphere, causing the observed rise in average global temperature and ocean acidification. Another direct effect is the CO2 fertilization effect. These changes cause a range of indirect effects of climate change on the physical environment, ecosystems and human societies. Carbon dioxide exerts a larger overall warming influence than all of the other greenhouse gases combined. It has an atmospheric lifetime that increases with the cumulative amount of fossil carbon extracted and burned, due to the imbalance that this activity has imposed on Earth's fast carbon cycle. This means that some fraction (a projected 20–35%) of the fossil carbon transferred thus far will persist in the atmosphere as elevated CO2 levels for many thousands of years after these carbon transfer activities begin to subside. The carbon cycle is a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and the biosphere. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis. Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds.
Carbon dioxide dissolves in the ocean to form carbonic acid (H2CO3), bicarbonate (HCO−3), and carbonate (CO2−3). There is about fifty times as much carbon dioxide dissolved in the oceans as exists in the atmosphere. The oceans act as an enormous carbon sink, and have taken up about a third of CO2 emitted by human activity.
Ocean acidification is the decrease in the pH of the Earth's ocean. Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO2) levels exceeding 410 ppm (in 2020). CO2 from the atmosphere is absorbed by the oceans. This produces carbonic acid (H2CO3) which dissociates into a bicarbonate ion (HCO−3) and a hydrogen ion (H). The presence of free hydrogen ions (H) lowers the pH of the ocean, increasing acidity (this does not mean that seawater is acidic yet; it is still alkaline, with a pH higher than 8). Marine calcifying organisms, such as mollusks and corals, are especially vulnerable because they rely on calcium carbonate to build shells and skeletons.
Changes in ocean chemistry can have extensive direct and indirect effects on organisms and their habitats. One of the most important repercussions of increasing ocean acidity relates to the production of shells out of calcium carbonate (CaCO3). This process is called calcification and is important to the biology and survival of a wide range of marine organisms. Calcification involves the precipitation of dissolved ions into solid CaCO3 structures, structures for many marine organisms, such as coccolithophores, foraminifera, crustaceans, mollusks, etc. After they are formed, these CaCO3 structures are vulnerable to dissolution unless the surrounding seawater contains saturating concentrations of carbonate ions (CO2−3).
Very little of the extra carbon dioxide that is added into the ocean remains as dissolved carbon dioxide. The majority dissociates into additional bicarbonate and free hydrogen ions. The increase in hydrogen is larger than the increase in bicarbonate, creating an imbalance in the reaction:
To maintain chemical equilibrium, some of the carbonate ions already in the ocean combine with some of the hydrogen ions to make further bicarbonate. Thus the ocean's concentration of carbonate ions is reduced, removing an essential building block for marine organisms to build shells, or calcify:
Carbon dioxide is also introduced into the oceans through hydrothermal vents. The Champagne hydrothermal vent, found at the Northwest Eifuku volcano in the Mariana Trench, produces almost pure liquid carbon dioxide, one of only two known sites in the world as of 2004, the other being in the Okinawa Trough. The finding of a submarine lake of liquid carbon dioxide in the Okinawa Trough was reported in 2006.
Carbon dioxide is a by-product of the fermentation of sugar in the brewing of beer, whisky and other alcoholic beverages and in the production of bioethanol. Yeast metabolizes sugar to produce CO2 and ethanol, also known as alcohol, as follows:
All aerobic organisms produce CO2 when they oxidize carbohydrates, fatty acids, and proteins. The large number of reactions involved are exceedingly complex and not described easily. Refer to (cellular respiration, anaerobic respiration and photosynthesis). The equation for the respiration of glucose and other monosaccharides is:
Anaerobic organisms decompose organic material producing methane and carbon dioxide together with traces of other compounds. Regardless of the type of organic material, the production of gases follows well defined kinetic pattern. Carbon dioxide comprises about 40–45% of the gas that emanates from decomposition in landfills (termed "landfill gas"). Most of the remaining 50–55% is methane.
Carbon dioxide can be obtained by distillation from air, but the method is inefficient. Industrially, carbon dioxide is predominantly an unrecovered waste product, produced by several methods which may be practiced at various scales.
The combustion of all carbon-based fuels, such as methane (natural gas), petroleum distillates (gasoline, diesel, kerosene, propane), coal, wood and generic organic matter produces carbon dioxide and, except in the case of pure carbon, water. As an example, the chemical reaction between methane and oxygen:
Iron is reduced from its oxides with coke in a blast furnace, producing pig iron and carbon dioxide:
Carbon dioxide is a byproduct of the industrial production of hydrogen by steam reforming and the water gas shift reaction in ammonia production. These processes begin with the reaction of water and natural gas (mainly methane). This is a major source of food-grade carbon dioxide for use in carbonation of beer and soft drinks, and is also used for stunning animals such as poultry. In the summer of 2018 a shortage of carbon dioxide for these purposes arose in Europe due to the temporary shut-down of several ammonia plants for maintenance.
It is produced by thermal decomposition of limestone, CaCO3 by heating (calcining) at about 850 °C (1,560 °F), in the manufacture of quicklime (calcium oxide, CaO), a compound that has many industrial uses:
Acids liberate CO2 from most metal carbonates. Consequently, it may be obtained directly from natural carbon dioxide springs, where it is produced by the action of acidified water on limestone or dolomite. The reaction between hydrochloric acid and calcium carbonate (limestone or chalk) is shown below:
The carbonic acid (H2CO3) then decomposes to water and CO2:
Such reactions are accompanied by foaming or bubbling, or both, as the gas is released. They have widespread uses in industry because they can be used to neutralize waste acid streams.
Carbon dioxide is used by the food industry, the oil industry, and the chemical industry. The compound has varied commercial uses but one of its greatest uses as a chemical is in the production of carbonated beverages; it provides the sparkle in carbonated beverages such as soda water, beer and sparkling wine.
In the chemical industry, carbon dioxide is mainly consumed as an ingredient in the production of urea, with a smaller fraction being used to produce methanol and a range of other products. Some carboxylic acid derivatives such as sodium salicylate are prepared using CO2 by the Kolbe–Schmitt reaction.
In addition to conventional processes using CO2 for chemical production, electrochemical methods are also being explored at a research level. In particular, the use of renewable energy for production of fuels from CO2 (such as methanol) is attractive as this could result in fuels that could be easily transported and used within conventional combustion technologies but have no net CO2 emissions.
Plants require carbon dioxide to conduct photosynthesis. The atmospheres of greenhouses may (if of large size, must) be enriched with additional CO2 to sustain and increase the rate of plant growth. At very high concentrations (100 times atmospheric concentration, or greater), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000 ppm (1%) or higher for several hours will eliminate pests such as whiteflies and spider mites in a greenhouse.
Carbon dioxide is a food additive used as a propellant and acidity regulator in the food industry. It is approved for usage in the EU (listed as E number E290), US and Australia and New Zealand (listed by its INS number 290).
A candy called Pop Rocks is pressurized with carbon dioxide gas at about 4,000 kPa (40 bar; 580 psi). When placed in the mouth, it dissolves (just like other hard candy) and releases the gas bubbles with an audible pop.
Leavening agents cause dough to rise by producing carbon dioxide. Baker's yeast produces carbon dioxide by fermentation of sugars within the dough, while chemical leaveners such as baking powder and baking soda release carbon dioxide when heated or if exposed to acids.
Carbon dioxide is used to produce carbonated soft drinks and soda water. Traditionally, the carbonation of beer and sparkling wine came about through natural fermentation, but many manufacturers carbonate these drinks with carbon dioxide recovered from the fermentation process. In the case of bottled and kegged beer, the most common method used is carbonation with recycled carbon dioxide. With the exception of British real ale, draught beer is usually transferred from kegs in a cold room or cellar to dispensing taps on the bar using pressurized carbon dioxide, sometimes mixed with nitrogen.
The taste of soda water (and related taste sensations in other carbonated beverages) is an effect of the dissolved carbon dioxide rather than the bursting bubbles of the gas. Carbonic anhydrase 4 converts to carbonic acid leading to a sour taste, and also the dissolved carbon dioxide induces a somatosensory response.
Carbon dioxide in the form of dry ice is often used during the cold soak phase in winemaking to cool clusters of grapes quickly after picking to help prevent spontaneous fermentation by wild yeast. The main advantage of using dry ice over water ice is that it cools the grapes without adding any additional water that might decrease the sugar concentration in the grape must, and thus the alcohol concentration in the finished wine. Carbon dioxide is also used to create a hypoxic environment for carbonic maceration, the process used to produce Beaujolais wine.
Carbon dioxide is sometimes used to top up wine bottles or other storage vessels such as barrels to prevent oxidation, though it has the problem that it can dissolve into the wine, making a previously still wine slightly fizzy. For this reason, other gases such as nitrogen or argon are preferred for this process by professional wine makers.
Carbon dioxide is often used to "stun" animals before slaughter. "Stunning" may be a misnomer, as the animals are not knocked out immediately and may suffer distress.
Carbon dioxide is one of the most commonly used compressed gases for pneumatic (pressurized gas) systems in portable pressure tools. Carbon dioxide is also used as an atmosphere for welding, although in the welding arc, it reacts to oxidize most metals. Use in the automotive industry is common despite significant evidence that welds made in carbon dioxide are more brittle than those made in more inert atmospheres. When used for MIG welding, CO2 use is sometimes referred to as MAG welding, for Metal Active Gas, as CO2 can react at these high temperatures. It tends to produce a hotter puddle than truly inert atmospheres, improving the flow characteristics. Although, this may be due to atmospheric reactions occurring at the puddle site. This is usually the opposite of the desired effect when welding, as it tends to embrittle the site, but may not be a problem for general mild steel welding, where ultimate ductility is not a major concern.
Carbon dioxide is used in many consumer products that require pressurized gas because it is inexpensive and nonflammable, and because it undergoes a phase transition from gas to liquid at room temperature at an attainable pressure of approximately 60 bar (870 psi; 59 atm), allowing far more carbon dioxide to fit in a given container than otherwise would. Life jackets often contain canisters of pressured carbon dioxide for quick inflation. Aluminium capsules of CO2 are also sold as supplies of compressed gas for air guns, paintball markers/guns, inflating bicycle tires, and for making carbonated water. High concentrations of carbon dioxide can also be used to kill pests. Liquid carbon dioxide is used in supercritical drying of some food products and technological materials, in the preparation of specimens for scanning electron microscopy and in the decaffeination of coffee beans.
Carbon dioxide can be used to extinguish flames by flooding the environment around the flame with the gas. It does not itself react to extinguish the flame, but starves the flame of oxygen by displacing it. Some fire extinguishers, especially those designed for electrical fires, contain liquid carbon dioxide under pressure. Carbon dioxide extinguishers work well on small flammable liquid and electrical fires, but not on ordinary combustible fires, because they do not cool the burning substances significantly, and when the carbon dioxide disperses, they can catch fire upon exposure to atmospheric oxygen. They are mainly used in server rooms.
Carbon dioxide has also been widely used as an extinguishing agent in fixed fire-protection systems for local application of specific hazards and total flooding of a protected space. International Maritime Organization standards recognize carbon-dioxide systems for fire protection of ship holds and engine rooms. Carbon-dioxide-based fire-protection systems have been linked to several deaths, because it can cause suffocation in sufficiently high concentrations. A review of CO2 systems identified 51 incidents between 1975 and the date of the report (2000), causing 72 deaths and 145 injuries.
Liquid carbon dioxide is a good solvent for many lipophilic organic compounds and is used to remove caffeine from coffee. Carbon dioxide has attracted attention in the pharmaceutical and other chemical processing industries as a less toxic alternative to more traditional solvents such as organochlorides. It is also used by some dry cleaners for this reason. It is used in the preparation of some aerogels because of the properties of supercritical carbon dioxide.
In medicine, up to 5% carbon dioxide (130 times atmospheric concentration) is added to oxygen for stimulation of breathing after apnea and to stabilize the O2/CO2 balance in blood.
Carbon dioxide can be mixed with up to 50% oxygen, forming an inhalable gas; this is known as Carbogen and has a variety of medical and research uses.
Another medical use are the mofette, dry spas that use carbon dioxide from post-volcanic discharge for therapeutic purposes.
Supercritical CO2 is used as the working fluid in the Allam power cycle engine.
Carbon dioxide is used in enhanced oil recovery where it is injected into or adjacent to producing oil wells, usually under supercritical conditions, when it becomes miscible with the oil. This approach can increase original oil recovery by reducing residual oil saturation by 7–23% additional to primary extraction. It acts as both a pressurizing agent and, when dissolved into the underground crude oil, significantly reduces its viscosity, and changing surface chemistry enabling the oil to flow more rapidly through the reservoir to the removal well. In mature oil fields, extensive pipe networks are used to carry the carbon dioxide to the injection points.
In enhanced coal bed methane recovery, carbon dioxide would be pumped into the coal seam to displace methane, as opposed to current methods which primarily rely on the removal of water (to reduce pressure) to make the coal seam release its trapped methane.
It has been proposed that CO2 from power generation be bubbled into ponds to stimulate growth of algae that could then be converted into biodiesel fuel. A strain of the cyanobacterium Synechococcus elongatus has been genetically engineered to produce the fuels isobutyraldehyde and isobutanol from CO2 using photosynthesis.
Researchers have developed a process called electrolysis, using enzymes isolated from bacteria to power the chemical reactions which convert CO2 into fuels.
Liquid and solid carbon dioxide are important refrigerants, especially in the food industry, where they are employed during the transportation and storage of ice cream and other frozen foods. Solid carbon dioxide is called "dry ice" and is used for small shipments where refrigeration equipment is not practical. Solid carbon dioxide is always below −78.5 °C (−109.3 °F) at regular atmospheric pressure, regardless of the air temperature.
Liquid carbon dioxide (industry nomenclature R744 or R-744) was used as a refrigerant prior to the use of dichlorodifluoromethane (R12, a chlorofluorocarbon (CFC) compound). CO2 might enjoy a renaissance because one of the main substitutes to CFCs, 1,1,1,2-tetrafluoroethane (R134a, a hydrofluorocarbon (HFC) compound) contributes to climate change more than CO2 does. CO2 physical properties are highly favorable for cooling, refrigeration, and heating purposes, having a high volumetric cooling capacity. Due to the need to operate at pressures of up to 130 bars (1,900 psi; 13,000 kPa), CO2 systems require highly mechanically resistant reservoirs and components that have already been developed for mass production in many sectors. In automobile air conditioning, in more than 90% of all driving conditions for latitudes higher than 50°, CO2 (R744) operates more efficiently than systems using HFCs (e.g., R134a). Its environmental advantages (GWP of 1, non-ozone depleting, non-toxic, non-flammable) could make it the future working fluid to replace current HFCs in cars, supermarkets, and heat pump water heaters, among others. Coca-Cola has fielded CO2-based beverage coolers and the U.S. Army is interested in CO2 refrigeration and heating technology.
Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers.
Carbon dioxide can be used as a means of controlling the pH of swimming pools, by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids. Similarly, it is also used in the maintaining reef aquaria, where it is commonly used in calcium reactors to temporarily lower the pH of water being passed over calcium carbonate in order to allow the calcium carbonate to dissolve into the water more freely, where it is used by some corals to build their skeleton.
Used as the primary coolant in the British advanced gas-cooled reactor for nuclear power generation.
Carbon dioxide induction is commonly used for the euthanasia of laboratory research animals. Methods to administer CO2 include placing animals directly into a closed, prefilled chamber containing CO2, or exposure to a gradually increasing concentration of CO2. The American Veterinary Medical Association's 2020 guidelines for carbon dioxide induction state that a displacement rate of 30–70% of the chamber or cage volume per minute is optimal for the humane euthanasia of small rodents. Percentages of CO2 vary for different species, based on identified optimal percentages to minimize distress.
Carbon dioxide is also used in several related cleaning and surface-preparation techniques.
Carbon dioxide was the first gas to be described as a discrete substance. In about 1640, the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original charcoal. His interpretation was that the rest of the charcoal had been transmuted into an invisible substance he termed a "gas" (from Greek "chaos") or "wild spirit" (spiritus sylvestris).
The properties of carbon dioxide were further studied in the 1750s by the Scottish physician Joseph Black. He found that limestone (calcium carbonate) could be heated or treated with acids to yield a gas he called "fixed air". He observed that the fixed air was denser than air and supported neither flame nor animal life. Black also found that when bubbled through limewater (a saturated aqueous solution of calcium hydroxide), it would precipitate calcium carbonate. He used this phenomenon to illustrate that carbon dioxide is produced by animal respiration and microbial fermentation. In 1772, English chemist Joseph Priestley published a paper entitled Impregnating Water with Fixed Air in which he described a process of dripping sulfuric acid (or oil of vitriol as Priestley knew it) on chalk in order to produce carbon dioxide, and forcing the gas to dissolve by agitating a bowl of water in contact with the gas.
Carbon dioxide was first liquefied (at elevated pressures) in 1823 by Humphry Davy and Michael Faraday. The earliest description of solid carbon dioxide (dry ice) was given by the French inventor Adrien-Jean-Pierre Thilorier, who in 1835 opened a pressurized container of liquid carbon dioxide, only to find that the cooling produced by the rapid evaporation of the liquid yielded a "snow" of solid CO2.
Carbon dioxide in combination with nitrogen was known from earlier times as Blackdamp, stythe or choke damp, Along with the other types of damp it was encountered in mining operations and well sinking. Slow oxidation of coal and biological processes replaced the oxygen to create a suffocating mixture of nitrogen and carbon dioxide. | [

In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.

Carbon dioxide exerts a larger overall warming influence than all of the other greenhouse gases combined. It has an atmospheric lifetime that increases with the cumulative amount of fossil carbon extracted and burned, due to the imbalance that this activity has imposed on Earth's fast carbon cycle. This means that some fraction (a projected 20–35%) of the fossil carbon transferred thus far will persist in the atmosphere as elevated CO2 levels for many thousands of years after these carbon transfer activities begin to subside.

Black also found that when bubbled through limewater (a saturated aqueous solution of calcium hydroxide), it would precipitate calcium carbonate. He used this phenomenon to illustrate that carbon dioxide is produced by animal respiration and microbial fermentation. In 1772, English chemist Joseph Priestley published a paper entitled Impregnating Water with Fixed Air in which he described a process of dripping sulfuric acid (or oil of vitriol as Priestley knew it) on chalk in order to produce carbon dioxide, and forcing the gas to dissolve by agitating a bowl of water in contact with the gas.",

] | Carbon dioxide is a chemical compound with the chemical formula CO2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. When carbon dioxide dissolves in water, it forms carbonate and mainly bicarbonate (HCO−3), which causes ocean acidification as atmospheric CO2 levels increase. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% having risen from pre-industrial levels of 280 ppm or about 0.025%. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change. Its concentration in Earth's pre-industrial atmosphere since late in the Precambrian was regulated by organisms and geological phenomena. Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product. In turn, oxygen is consumed and CO2 is released as waste by all aerobic organisms when they metabolize organic compounds to produce energy by respiration. CO2 is released from organic materials when they decay or combust, such as in forest fires. Since plants require CO2 for photosynthesis, and humans and animals depend on plants for food, CO2 is necessary for the survival of life on earth. Carbon dioxide is 53% more dense than dry air, but is long lived and thoroughly mixes in the atmosphere. About half of excess CO2 emissions to the atmosphere are absorbed by land and ocean carbon sinks. These sinks can become saturated and are volatile, as decay and wildfires result in the CO2 being released back into the atmosphere. CO2 is eventually sequestered in rocks and organic deposits like coal, petroleum and natural gas. Sequestered CO2 is released into the atmosphere through burning fossil fuels or naturally by volcanoes, hot springs, geysers, and when carbonate rocks dissolve in water or react with acids. CO2 is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, and as a supercritical fluid solvent in decaffeination of coffee and supercritical drying. It is a byproduct of fermentation of sugars in bread, beer and wine making, and is added to carbonated beverages like seltzer and beer for effervescence. It has a sharp and acidic odor and generates the taste of soda water in the mouth, but at normally encountered concentrations it is odorless. | 2001-07-29T19:43:30Z | 2023-12-25T03:55:21Z | [

5,907 | Cheers | Cheers is an American sitcom television series that ran on NBC from 1982 to 1993, with a total of 275 22-26 minute episodes across 11 seasons. The show was produced by Charles/Burrows/Charles Productions in association with Paramount Network Television and was created by the team of James Burrows and Glen and Les Charles. The show is set in the titular bar in Boston, where a group of locals meet to drink, relax, socialize and hide from their day to day issues.
At the center of the show is the bar's owner and head bartender, Sam Malone, who is a womanizing former relief pitcher for the Boston Red Sox. The show's ensemble cast introduced in the pilot episode are waitresses Diane Chambers and Carla Tortelli, second bartender Coach Ernie Pantusso, and regular customers Norm Peterson and Cliff Clavin. Later main characters of the show also include Frasier Crane, Woody Boyd, Lilith Sternin, and Rebecca Howe.
After premiering in 1982, it was nearly canceled during its first season when it ranked almost last in ratings for its premiere (74th out of 77 shows). However, Cheers eventually became a Nielsen ratings juggernaut in the United States, earning a top-10 rating during eight of its 11 seasons, including one season at number one (season 9). The show spent most of its run on NBC's Thursday night "Must See TV" lineup. Its widely watched series finale in 1993 became the most watched single TV episode of the 1990s, and the show's 275 episodes have been successfully syndicated worldwide. Nominated for Outstanding Comedy Series for all 11 of its seasons on the air, it earned 28 Primetime Emmy Awards from a record of 117 nominations.
During its run, Cheers became one of the most popular series in history and received critical acclaim from its start to its end. In 1997, the episodes "Thanksgiving Orphans" and "Home Is the Sailor", aired originally in 1987, were respectively ranked No. 7 and No. 45 on TV Guide's 100 Greatest Episodes of All Time. Its series finale was watched by an estimated 93 million viewers, almost 40% of the US population at the time. The series also produced three spin-offs: The Tortellis, Wings, and Frasier; and a Spanish remake. In 2002, Cheers was ranked No. 18 on TV Guide's 50 Greatest TV Shows of All Time. In 2013, the Writers Guild of America ranked it as the eighth-best-written TV series and TV Guide ranked it No. 11 on their list of the 60 greatest shows.
Before the Cheers pilot "Give Me a Ring Sometime" was completed and aired in 1982, the series consisted of four employees in the first script. Neither Norm Peterson nor Cliff Clavin, regular customers of Cheers, were featured; later revisions added them as among the regular characters of the series.
In later years, Woody Boyd replaced Coach, after the character died off-screen in season three (1984–85), following actor Nicholas Colasanto's death. Frasier Crane started as a recurring character and became a permanent one. In season six (1987–88), new character Rebecca Howe was added, having been written into the show after the finale of the previous season (1986–87). Lilith Sternin started as a one-time character in an episode of season four, "Second Time Around" (1985). After her second season five appearance, she became a recurring character and was later featured as a permanent one during season 10 (1991–92).
Although Cheers operated largely around that main ensemble cast and their interactions with various one-off characters, guest stars and recurring characters did occasionally supplement them. Notable repeat guests included Dan Hedaya as Nick Tortelli and Jean Kasem as Loretta Tortelli (who were the main characters in the first spin-off, The Tortellis), Fred Dryer as Dave Richards, Annie Golden as Margaret O'Keefe, Derek McGrath as Andy Schroeder (also referred to as Andy Andy), interchangeably Joel Polis and Robert Desiderio as rival bar owner Gary, Jay Thomas as Eddie LeBec, Roger Rees as Robin Colcord, Tom Skerritt as Evan Drake, Frances Sternhagen as Esther Clavin, Richard Doyle as Walter Gaines, Keene Curtis as John Allen Hill, Anthony Cistaro as Henri, Michael McGuire as Professor Sumner Sloan, and Harry Anderson as Harry "The Hat" Gittes. Jackie Swanson, who played the recurring role of Woody's girlfriend and eventual wife "Kelly Gaines-Boyd", appeared in 24 episodes from 1989 to 1993. The character is as equally dim and naive—but ultimately as sweet-natured—as Woody.
Paul Willson played the recurring barfly character Paul Krapence. (In one early appearance in the first season he was called "Glen", and was later credited on-screen as "Gregg" and "Tom", but he was playing the same character throughout.) Thomas Babson played "Tom", a law student often mocked by Cliff Clavin, for continually failing to pass the Massachusetts bar exam. "Al", played by Al Rosen, appeared in 38 episodes, and was known for his surly quips. Rhea Perlman's father Philip Perlman played the role of "Phil".
Other celebrities guest-starred in single episodes as themselves throughout the series. Sports figures appeared on the show as themselves, with a connection to Boston or Sam's former team, the Red Sox, such as Luis Tiant, Wade Boggs, and Kevin McHale (of the Boston Celtics). Some television stars also made guest appearances as themselves such as Alex Trebek, Arsenio Hall, Dick Cavett, Robert Urich, George McFarland and Johnny Carson. Various political figures even made appearances on Cheers such as then-Chairman of the Joint Chiefs of Staff Admiral William J. Crowe, former Colorado Senator Gary Hart, then-Speaker of the House Tip O'Neill, then-Senator John Kerry, then-Governor Michael Dukakis, Ethel Kennedy (widow of Robert F. Kennedy), and then-Mayor of Boston Raymond Flynn, the last five of whom all represented Cheers' home state and city.
In maternal roles, Glynis Johns, in a guest appearance in 1983, played Diane's mother, Helen Chambers. Nancy Marchand played Frasier's mother, Hester Crane, in an episode that aired in 1985. In an episode that aired in 1992, Celeste Holm – who had previously played Ted Danson's mother in "Three Men and a Baby" – appeared as Kelly's jokester of a paternal grandmother. Melendy Britt appeared in the episode "Woody or Won't He" (1990) as Kelly's mother, Roxanne Gaines, a very attractive high-society lady and a sexy, flirtatious upper-class cougar who tries to seduce Woody.
The musician Harry Connick Jr. appeared in an episode as Woody's cousin and plays a song from his Grammy-winning album We Are in Love (c. 1991). John Cleese won a Primetime Emmy Award for his guest appearance as "Dr. Simon Finch-Royce" in the fifth-season episode "Simon Says". Emma Thompson guest-starred as Nanny G/Nannette Guzman, a famous singing nanny and Frasier's ex-wife. Christopher Lloyd guest-starred as a tortured artist who wanted to paint Diane. Marcia Cross portrayed Rebecca's sister Susan in the season 7 episode Sisterly Love. John Mahoney once appeared as an inept jingle writer, which included a brief conversation with Frasier Crane, whose father he later portrayed on the spin-off Frasier. Peri Gilpin, who later played Roz Doyle on Frasier, also appeared in one episode of Cheers, in its 11th season, as Holly Matheson, a reporter who interviews Woody. The Righteous Brothers, Bobby Hatfield and Bill Medley, also guest-starred in different episodes. In "The Guy Can't Help It", Rebecca meets a plumber, played by Tom Berenger, who came to fix one of the beer keg taps. They marry in the series finale, triggering her resignation from Cheers. Judith Barsi appears in the episode Relief Bartender.
Notable guest appearances of actresses portraying Sam's sexual conquests or potential sexual conquests include Kate Mulgrew in the three-episode finale of season four, portraying Boston councilwoman Janet Eldridge; Donna McKechnie as Debra, Sam's ex-wife (with whom he is on good terms), who pretends to be an intellectual in front of Diane; Barbara Babcock as Lana Marshall, a talent agent who specializes in representing male athletes, with whom she routinely sleeps on demand; Julia Duffy as Rebecca Prout, a depressed intellectual friend of Diane's; Alison LaPlaca as magazine reporter Paula Nelson; Carol Kane as Amanda, who Sam eventually learns was a fellow patient at the sanitarium with Diane; Barbara Feldon as Lauren Hudson, Sam's annual Valentine's Day fling (in an homage to Same Time, Next Year); Sandahl Bergman as Judy Marlowe, a longtime casual sex partner and whose now grown daughter, Laurie Marlowe (Chelsea Noble), who has always considered Sam a pseudo-father figure, Sam falls for; Madolyn Smith-Osborne as Dr. Sheila Rydell, a colleague of Frasier and Lilith; Valerie Mahaffey as Valerie Hill, John Allen Hill's daughter whom Sam pursues if only to gain an upper hand in his business relationship with Hill; and Alexis Smith as Alice Anne Volkman, Rebecca's much older ex-professor. In season 9, episode 17, "I'm Getting My Act Together and Sticking It in Your Face", Sam, believing Rebecca wants a more serious relationship, pretends to be gay, his lover being a casual friend named Leon (Jeff McCarthy)—the plan ultimately leads to a kiss between Sam and Leon.
Near the end of production of the third season, the writers of Cheers had to deal with the death of one of the main actors. Nicholas Colasanto's heart condition had been diagnosed in the mid-1970s, but it had worsened. He had lost weight and was having trouble breathing during filming, and he was hospitalized shortly before filming finished for season three due to fluid in his lungs. He recovered but was not cleared to return to work. He was visiting the set in January 1985 to watch the filming of several episodes, and co-star Shelley Long commented, "I think we were all in denial. We were all glad he was there, but he lost a lot of weight." Co-star Rhea Perlman added that he "wanted to be there so badly. He didn't want to be sick. He couldn't breathe well. It was hard. He was laboring all the time." Colasanto ultimately died of a heart attack at his home on February 12, 1985.
The third-season episodes of Cheers were filmed out of order, partly to accommodate Shelley Long's pregnancy. As a result, they had already completed filming the season finale at the time of his death, which had scenes with Colasanto in it. As the remaining episodes were filmed, Coach's absence was explained by having one of the characters mention that Coach was out of town for various reasons.
The Cheers writing staff assembled in June 1985 to discuss how to deal with the absence of Coach. They quickly discarded the idea that he had moved away, as they felt that he would never abandon his friends. In addition, most viewers were aware of Colasanto's death, so the writing staff decided to handle the situation more openly. The season four opener, "Birth, Death, Love and Rice", dealt with Coach's death and introduced Woody Harrelson, Colasanto's replacement.
Nearly all of Cheers takes place in the front room of the bar, but the characters often go into the rear pool room or the bar's office. Cheers does not show any action outside the bar until the first episode of the second season, which takes place in Diane's apartment.
The show's main theme in its early seasons is the romance between intellectual waitress Diane Chambers and the bar's owner, Sam Malone, a former Major League Baseball pitcher for the Boston Red Sox and recovering alcoholic. After Shelley Long (Diane) left the show, the focus shifted to Sam's new relationship with Rebecca Howe, a neurotic corporate ladder climber.
Many Cheers scripts centered or touched upon a variety of social issues, albeit humorously. As Toasting Cheers puts it, "The script was further strengthened by the writers' boldness in successfully tackling controversial issues such as alcoholism, homosexuality, and adultery."
Social class was a subtext of the show. The "upper class" — represented by characters like Diane Chambers, Frasier Crane, and Lilith Sternin — rub shoulders with middle- and working-class characters Sam Malone, Carla Tortelli, Norm Peterson, and Cliff Clavin. An extreme example of this was the relationship between Woody Boyd and a millionaire's daughter, Kelly Gaines. Many viewers enjoyed Cheers in part because of this focus on character development in addition to plot development.
Feminism and the role of women were also recurring themes throughout the show, with some critics seeing each of the major female characters portraying an aspect as a flawed feminist in her own way. Diane is a vocal feminist, and Sam is the epitome of everything she hates: promiscuity and chauvinism (see "Sam and Diane").
Homosexuality was dealt with from the first season, which was rare in the early 1980s on American television. In the first-season episode "The Boys in the Bar" (the title being a reference to the play and subsequent movie The Boys in the Band), a friend and former teammate of Sam's comes out in his autobiography. Some of the male regulars pressure Sam to take action to ensure that Cheers does not become a gay bar. The episode won a GLAAD Media Award, and the script's writers, Ken Levine and David Isaacs, were nominated for a Primetime Emmy Award.
Addiction also plays a role on Cheers, almost exclusively through Sam. He is a recovering alcoholic who had bought a bar during his drinking days. Frasier has a notable bout of drinking in the fourth-season episode "The Triangle", while Woody develops a gambling problem in the seventh season's "Call Me Irresponsible". Carla and other characters drink beer while pregnant, but nobody seems to mind.
Cheers had several owners before Sam, as the bar was opened in 1889. The "Est. 1895" on the bar's sign is a made-up date chosen by Carla for numerology purposes, revealed in season 8, episode 6, "The Stork Brings a Crane", which also revealed the bar's address as 1121⁄2 Beacon Street and that it originated under the name Mom's. In the series' second episode, "Sam's Women", Coach tells a customer looking for Gus, the owner of Cheers, that Gus is dead. In a later episode, Gus O'Mally comes back from Arizona for one night and helps run the bar.
The biggest storyline surrounding the ownership of Cheers begins in the fifth-season finale, "I Do, Adieu", when Sam and Diane part ways, due to Shelley Long's departure from the series. In addition, Sam leaves on a trip to circumnavigate the globe. Before he leaves, he sells Cheers to the Lillian Corporation. He returns in the sixth-season premiere, "Home is the Sailor", having sunk his boat, to find the bar under the new management of Rebecca Howe. He begs for his job back and is hired by Rebecca as a bartender. In the seventh-season premiere, "How to Recede in Business", Rebecca is fired and Sam is promoted to manager. Rebecca is allowed to keep a job at Lillian vaguely similar to what she had before, but only after Sam has Rebecca (in absentia) "agree" to a long list of demands that the corporation had for her.
From there, Sam occasionally attempts to buy the bar back with schemes that usually involve the wealthy executive Robin Colcord. Sam acquires Cheers again in the eighth-season finale, when it is sold back to him for 85¢ by the Lillian Corporation after he alerts the company to Colcord's insider trading. Fired by the corporation because of her silence on the issue, Rebecca is hired by Sam as a hostess/office manager. For the rest of the episode, to celebrate Sam's reclaiming the bar, a huge banner reading "Under OLD Management!" hangs from the staircase. When it is learned that the Pool Room and bathrooms are actually owned by Melville's (which spawns a war of wits between Sam and Melville's owner John Allen Hill), Rebecca later purchases them from Hill, making Sam and Rebecca partners in the ownership of Cheers (and more or less co-runners of the establishment).
Sam has two main battles. One is with Gary's Olde Towne Tavern, trying to beat them at some activity or another but always failing, except for one episode when Diane helps Cheers win the bowling trophy, and extending to the practical jokes they play on each other. The second is with Melville's owner John Allen Hill, who keeps annoying Sam with his pettiness and ego. Hill had an ongoing relationship with Carla.
Some believe that the show is a rehashing of Boston's ABC affiliate WCVB's locally produced 1979 sitcom Park Street Under featuring Steve Sweeney and American Repertory Theater founder Karen MacDonald. Three men developed and created the Cheers television series: Glen and Les Charles ("Glen and Les") and James Burrows, who identified themselves as "two Mormons and a Jew." They aimed at "creating a show around a Spencer Tracy-Katharine Hepburn-type relationship" between their two main characters, Sam and Diane. Malone represents the average man, while Chambers represents class and sophistication. The show revolves around characters in a bar under "humorous adult themes" and "situations".
The original idea was a group of workers who interacted like a family, the goal being a concept similar to The Mary Tyler Moore Show. The creators considered making an American version of the British Fawlty Towers, set in a hotel or an inn. When the creators settled on a bar as their setting, the show began to resemble the radio program Duffy's Tavern, originally written and cocreated by James Burrows' father Abe Burrows. They liked the idea of a tavern, as it provided a continuous stream of new people, for a variety of characters. An early concept revolved around a woman becoming the new owner of the bar and the animosity created between her and the regulars, an idea that was used later in Season 6 when the character of Rebecca Howe is introduced.
Early discussions about the location of the show centered on Barstow, California, then Kansas City, Missouri. They eventually turned to the East Coast and finally Boston. The Bull & Finch Pub in Boston, which was the model for Cheers, was chosen from a phone book. When Glen Charles asked the bar's owner, Tom Kershaw, to shoot exterior and interior photos, he agreed, charging $1. Kershaw has since gone on to make millions of dollars, licensing the pub's image and selling a variety of Cheers memorabilia. The Bull & Finch became the 42nd-busiest outlet in the American food and beverage industry in 1997. During initial casting, Shelley Long, who was in Boston at the time filming A Small Circle of Friends, remarked that the bar in the script resembled a bar she had come upon in the city, which turned out to be the Bull & Finch.
The crew of Cheers numbered in the hundreds. The three creators—James Burrows and Glen and Les Charles—kept offices on Paramount's lot for the duration of the Cheers run. The Charles Brothers remained in overall charge throughout the show's run, frequently writing major episodes, though starting with the third season they began delegating the day-to-day running of the writing staff to various showrunners. Ken Estin and Sam Simon were appointed as showrunners for the third season, and succeeded by David Angell, Peter Casey and David Lee the following year. Angell, Casey and Lee would remain as showrunners until the end of the seventh season when they left to develop their own sitcom, Wings, and were replaced by Bill and Cheri Steinkellner and Phoef Sutton for the eighth through tenth seasons. For the final season, Tom Anderson and Dan O'Shannon acted as the showrunners.
James Burrows is regarded as being a factor in the show's longevity, directing 243 of the 270 episodes and supervising the show's production. Among the show's other directors were Andy Ackerman, Thomas Lofaro, Tim Berry, Tom Moore, Rick Beren, as well as cast members John Ratzenberger and George Wendt.
Craig Safan provided the series' original music for its entire run except the theme song. His extensive compositions for the show led to his winning numerous ASCAP Top TV Series awards for his music.
The character of Sam Malone was originally intended to be a retired football player and was slated to be played by Fred Dryer, but Danson was chosen in part because he was younger and had more acting experience than Dryer. After casting Ted Danson, it was decided that a former baseball player (Sam "Mayday" Malone) would be more believable than a retired football player. Dryer, however, went on to play sportscaster Dave Richards, an old friend of Sam, in three episodes. Bill Cosby was also considered early in the casting process for the role of Sam, after having been recommended by the network.
Shelley Long was recommended by various sources to the producers for the role of Diane Chambers, but Long wished to be offered the part straight out and had to be coaxed into giving an audition. When she did read for the part, according to Glen Charles, "that was it, we knew that we wanted her." Before the final decision was made, three pairs of actors were tested in front of the producers and network executives for Sam and Diane: Danson and Long, Fred Dryer and Julia Duffy, and William Devane and Lisa Eichhorn. The chemistry was so apparent between Long and Danson that it secured them the roles. Ted Danson was sent to bartending school to prepare him for the part and according to Burrows, had to learn "how to pretend that he knew a lot about sports" since Danson was not a sports fan in real life and had never been to a baseball game.
The character of Cliff Clavin was created for John Ratzenberger after he auditioned for the role of Norm Peterson, which eventually went to George Wendt. While chatting with producers afterward, he asked if they were going to include a "bar know-it-all", the part he eventually played. Alley joined the cast when Shelley Long left, and Woody Harrelson joined when Nicholas Colasanto died. Danson, Perlman and Wendt were the only actors to appear in every episode of the series; Ratzenberger appears in all but one (and his name wasn't part of the opening credit montage during the first season).
"On Cheers, we never did everything twice. On Cheers, we went through the scene and I only reshot jokes that didn't work or I went back and picked up shots I missed."
James Burrows
Most Cheers episodes were, as a voiceover stated at the start of each, "filmed before a live studio audience" on Paramount Stage 25 in Hollywood, generally on Tuesday nights. Scripts for a new episode were issued the Wednesday before for a read-through, Friday was rehearsal day, and final scripts were issued on Monday. Burrows, who directed most episodes, insisted on using film stock rather than videotape. He was also noted for using motion in his directorial style, trying to constantly keep characters moving rather than standing still. Burrows and the Charles brothers emphasized to the cast to "never assume that you're not being watched" because the camera would be focused on the actors at all times, so they had to always be reacting and "always be funny". During the first season when ratings were poor Paramount and NBC asked that the show use videotape to save money, but a poor test taping ended the experiment and Cheers continued to use film.
Due to a decision by Glen and Les Charles, the cold open was often not connected to the rest of the episode, with the lowest-ranked writers assigned to create the jokes for them. Some cold opens were taken from episodes that ran too long.
The first year of the show took place entirely within the confines of the bar, the first location outside the bar being Diane's apartment in the second year. When the series became a hit, the characters started venturing further afield, first to other sets and eventually to an occasional exterior location. The exterior location shots of the bar are of the Bull & Finch Pub, located directly north of the Boston Public Garden. The pub has become a tourist attraction because of its association with the series, and draws nearly one million visitors annually. It has since been renamed Cheers Beacon Hill; its interior is different from the TV bar. The pub itself is at 84 Beacon Street (on the corner of Brimmer Street). In August 2001, there was a replica made of the bar in Faneuil Hall to capitalize on the popularity of the show.
After the show ended, the 1,000-square-foot bar set from Cheers was offered to the Smithsonian, which turned it down because it was too large. It was displayed for a short time at the defunct Hollywood Entertainment Museum, but later returned to storage, where it remained for many years. In 2014, CBS donated the set to the Museum of Television after a years-long campaign by James Burrows and his office on behalf of the museum's founder, James Comisar. At the time of the donation, Comisar initiated a planned $100,000 restoration of the set using former conservators from the Los Angeles County Museum of Art, although a site for the 10,000 item collection of the museum had not been decided upon.
Before "Where Everybody Knows Your Name", written by Gary Portnoy and Judy Hart Angelo, became the show's theme song, Cheers' producers rejected two of Portnoy's and Hart Angelo's songs. The songwriters had collaborated to provide music for Preppies, an unsuccessful Broadway musical. When told they could not appropriate "People Like Us", Preppies' opening song, the pair wrote another song, "My Kind of People", which resembles "People Like Us" and was intended to satirize "the lifestyle of old decadent old-money WASPs", but to meet producers' demands, they rewrote the lyrics to be about "likeable losers" in a Boston bar. The show's producers rejected this song, as well. After they read the script of the series pilot, they created another song "Another Day". When Portnoy and Hart Angelo heard that NBC had commissioned thirteen episodes, they created an official theme song "Where Everybody Knows Your Name" and rewrote the lyrics. On syndicated airings of Cheers, the theme song was shortened to make room for additional commercials.
Cheers was critically acclaimed in its first season, though it landed a disappointing 74th out of 96 shows in that year's ratings. This critical support, the early success at the Primetime Emmy Awards, and the support of the president of NBC's entertainment division Brandon Tartikoff, are thought to be the main reasons for the show's survival and eventual success. Tartikoff stated in 1983 that Cheers was a sophisticated adult comedy and that NBC executives "never for a second doubted" that the show would be renewed. Writer Levine believes that the most important reason was that the network recognized that it did not have other hit shows to help promote Cheers; as he later wrote, "[NBC] had nothing else better to replace it with."
Writing in 2016, drama critic Chris Jones called Cheers "a hinge sitcom – one foot in classic bits and shtick not far removed from Mel Brooks and another in ambitious, Seinfeld-like absurdism." In 2013, GQ magazine held an online competition to find the best TV comedy. Cheers was voted the greatest comedy show of all time. In 2017, James Charisma of Paste magazine ranked the show's opening sequence No. 5 on a list of The 75 Best TV Title Sequences of All Time. In 2022, Rolling Stone ranked Cheers as the eighth-greatest TV show of all time. In 2023, Variety ranked Cheers #11 on its list of the 100 greatest TV shows of all time.
Ratings improved for the summer reruns after the first season. The cast went on various talk shows to try to further promote the series after its first season. By the second season Cheers was competitive with CBS's top-rated show Simon & Simon. With the growing popularity of Family Ties, which ran in the slot ahead of Cheers from January 1984 until Family Ties was moved to Sundays in 1987, and the placement of The Cosby Show in front of both at the start of their third season (1984), the line-up became a runaway ratings success that NBC eventually dubbed "Must See Thursday". The next season, Cheers ratings increased dramatically after Woody Boyd became a regular character as well. The fifth season earned the series the highest rating for the year that it would ever achieve. Although ratings mostly declined each year after that, the show retained a competitive advantage and rose to rank number one for the year for its first and only time in the ninth season. Although ratings and ranking both lost ground in the last two seasons, it still performed well, as it was the only show on NBC during those seasons to be in the top 10. By the end of its final season, the show had a run of eight consecutive seasons in the top ten of the Nielsen ratings; seven of them were in the top five.
NBC dedicated a whole night to the final episode of Cheers, following the one-hour season finale of Seinfeld (which was its lead-in). The show began with a "pregame" show hosted by Bob Costas, followed by the final 98-minute episode itself. NBC affiliates then aired tributes to Cheers during their local newscasts, and the night concluded with a special Tonight Show broadcast live from the Bull & Finch Pub. Although the episode fell short of its hyped ratings predictions to become the most-watched television episode, it was the most watched show that year, bringing in 93 million viewers (64 percent of all viewers that night), almost 40% of the US population at the time, and ranked 11th all time in entertainment programming. The 1993 final broadcast of Cheers also emerged as the highest rated broadcast of NBC to date, as well as the most watched single episode from any television series throughout the decade 1990s on U.S. television.
The episode originally aired in the usual Cheers spot of Thursday night, and was then rebroadcast on Sunday. While the original broadcast did not outperform the M*A*S*H finale, the combined non-repeating audiences for the Thursday and Sunday showings did. Television had greatly changed between the two finales, leaving Cheers with a broader array of competition for ratings.
NBC timeslots:
Although not the first sitcom to do it, Cheers employed the use of end-of-season cliffhangers and, starting with the third season, the show's storylines became more serialized. The show's success helped make such multi-episode story arcs popular on sitcoms, which Les Charles regrets.
[W]e may have been partly responsible for what's going on now, where if you miss the first episode or two, you are lost. You have to wait until you can get the whole thing on DVD and catch up with it. If that blood is on our hands, I feel kind of badly about it. It can be very frustrating."
Cheers began with a limited five-character ensemble consisting of Ted Danson, Shelley Long, Rhea Perlman, Nicholas Colasanto and George Wendt. Cheers was able to gradually phase in characters such as Cliff, Frasier, Lilith, Rebecca, and Woody. By the time season 10 began, the show had eight front characters in its roster.
Over its eleven-season run, the Cheers cast and crew earned many awards. The show garnered a record 111 Primetime Emmy Award nominations, with a total of 28 wins. In addition, Cheers earned 31 Golden Globe nominations, with a total of six wins. Danson, Long, Alley, Perlman, Wendt, Ratzenberger, Harrelson, Grammer, Neuwirth, and Colasanto all received Emmy nominations for their roles. Cheers won the Golden Globe Award for "Best TV-Series – Comedy/Musical" in 1991 and the Primetime Emmy Award for Outstanding Comedy Series in 1983, 1984, 1989, and 1991. The series was presented with the "Legend Award" at the 2006 TV Land Awards, with many of the surviving cast members attending the event.
The following are awards that have been earned by the Cheers cast and crew over its 11-season run:
Cheers grew in popularity as it aired on American television and entered off-network syndication in 1987, initially distributed by Paramount Domestic Television. When the show went off the air in 1993, Cheers was syndicated in 38 countries, with 179 American television markets and 83 million viewers. When the quality of some earlier footage of Cheers began to deteriorate, it underwent a careful restoration in 2001. The series aired on Nick at Nite from 2001 to 2004 and on TV Land from 2004 to 2008, with Nick at Nite airing week-long Cheers "Everybody Knows Your Name" marathons. The show was removed from the lineup in 2004. The series began airing on Hallmark Channel in the United States in October 2008, and WGN America in 2009. In January 2011, Reelz Channel began airing the series in hour-long blocks. MeTV began airing Cheers weeknights in 2010. USA Network has aired the series on Sunday early mornings and weekday mornings to allow it to show extended-length films of 2+1⁄2 hours and maintain symmetric schedules.
In 2011, Cheers was made available on the Netflix and Amazon Prime Video streaming services.
Cheers began airing on Eleven (a digital channel of Network Ten) in Australia on January 11, 2011. NCRV in the Netherlands aired all 275 episodes in sequence, once per night, repeating the series a total of three times.
In Italy, Cheers aired on Italia 1 & Canale 5 as Cin Cin from 1985 until 1988.
Cheers was first screened in the UK on Channel 4, and was one of the then-fledgling network's first imports. As of 2012, Cheers has been repeated on UK satellite channel CBS Drama. It has also been shown on the UK free-to-air channel ITV4, with two episodes every weeknight. On March 16, 2015, the series began airing on UK subscription channel Gold on weekdays at 9:30 a.m. and 10:00 a.m. Cheers aired again daily in 2019 on Channel 4.
A high-definition transfer of Cheers began running on HDNet in the United States in August 2010. The program was originally shot on film (but transferred to and edited on videotape) and broadcast in a 4:3 aspect ratio, but the newly transferred versions are in 16:9. However, in the United Kingdom, the HD repeats on ITV4 HD, and later Channel 4 HD, are shown in the original 4:3 aspect ratio.
Paramount Home Entertainment and (from 2006 onward) CBS Home Entertainment have released all 11 seasons of Cheers on DVD in Region 1, Region 2, and Region 4. In the US, some episodes from the final three seasons appear on the DVDs with music substitutions. For example, in the episode "Grease", "I Fought the Law" was replaced even though its removal affects the comedic value of the scenes in which it was originally heard. The finale episode (73 minutes long without commercials) is presented in its three-part syndicated cut.
On March 6, 2012, CBS released Fan Favorites: The Best of Cheers. Based on the 2012 Facebook poll, the selected episodes are:
On May 5, 2015, CBS DVD released Cheers – The Complete Series on DVD in Region 1.
The complete 11 seasons of Cheers are available through the iTunes Store, Amazon Prime Video, Peacock and Hulu. In Canada, all seasons are available on streaming service Crave.
The entire series is available in the UK on All 4.
The series lent itself naturally to the development of Cheers bar-related merchandise, culminating in the development of a chain of Cheers themed pubs. Paramount's licensing group, led by Tom McGrath, developed the Cheers pub concept initially in partnership with Host Marriott, which placed Cheers themed pubs in over 15 airports around the world. Boston boasts the original Cheers bar, historically known to Boston insiders as the Bull and Finch; a Cheers restaurant in the Faneuil Hall marketplace; and Sam's Place, a spin-off sports bar concept also located in Faneuil Hall. In 1997, Europe's first officially licensed Cheers bar opened in London's Regent's Street W1. Like Cheers Faneuil Hall, Cheers London is a replica of the set. The gala opening was attended by James Burrows and cast members George Wendt and John Ratzenberger. The Cheers bar in London closed on December 31, 2008. The actual bar set had been on display at the Hollywood Entertainment Museum until the museum's closing in early 2006.
The theme song to the show was eventually licensed to a Canadian restaurant, Kelsey's Neighbourhood Bar & Grill.
CBS currently holds the rights to the Cheers franchise as a result of the 2005 Viacom split which saw Paramount transfer its entire television studio to CBS (both CBS and Viacom would reunite in 2019).
Some of the actors and actresses from Cheers brought their characters onto other television shows, either in a guest appearance or on a new spin-off series. The most successful Cheers spin-off was Frasier, which featured Frasier Crane following his relocation back to Seattle, Washington. Sam, Diane, and Woody all individually appeared in Frasier episodes, with Lilith appearing as a guest on multiple episodes. In the season nine episode "Cheerful Goodbyes", Frasier returns to Boston and meets up with the Cheers gang, later attending Cliff's retirement party. Frasier was revived in 2023, moving back to Boston like Cheers.
Although Frasier was more successful, The Tortellis was the first series to spin off from Cheers, premiering in 1987. The show featured Carla's ex-husband Nick Tortelli and his wife Loretta, but was canceled after 13 episodes and drew protests for its stereotypical depictions of Italian Americans.
In addition to direct spin-offs, several Cheers characters had guest appearance crossovers with other shows, including Wings and St. Elsewhere (episode "Cheers"). Cheers has also been spoofed or referenced in other media, including The Simpsons (spoofing the title sequence and theme song in "Flaming Moe's"; actually visiting the place with vocal role reprises of the majority of the principal cast in "Fear of Flying"), Scrubs (episode "My Life in Four Cameras"), and the 2012 comedy film Ted.
The eighth-anniversary special of Late Night with David Letterman, airing in 1990, begins with a scene at Cheers in which the bar's TV gets stuck on NBC and all the bar patrons decide to go home instead of staying to watch David Letterman. The scene was re-used to open Letterman's final episode in 1993. A similar scene aired in the Super Bowl XVII Pregame Show on NBC, in which the characters briefly discuss the upcoming game.
In 2019, members of the Cheers cast, Rhea Perlman, George Wendt, John Ratzenberger and Kirstie Alley reprised their characters in an episode of The Goldbergs where they play customers of Geoff's short-lived food delivery business.
In the 2010 show Adventure Time, the show Cheers is referenced a few times, usually by Ice King/Simon because it was his favorite show back when he was a human living in the 20th century. This is explored in greater detail in the 2023 spin-off series Fionna and Cake, which is partially set within the mind of Simon. All televisions in that world simply play an animated rendition of Cheers reruns on every channel, and the characters sometimes sing the theme song in difficult moments. The season finale of the show is simply entitled "Cheers".
In Australia, Cheers is remembered for its role in the infamous cancellation of the 1992 Nine Network special Australia's Naughtiest Home Videos. Due to the then-owner of Nine Network Kerry Packer's objections to its content, Australia's Naughtiest Home Videos was pulled off the air during its first and only broadcast; viewers saw the network abruptly begin airing a rerun of Cheers midway through the special, either after a scheduled commercial break or a Nine Network bumper claiming a technical problem. Nine Network's affiliate in Perth didn't air the special at all and filled its timeslot with two episodes of Cheers. When the program was re-aired in its entirety in 2008, it abruptly cut away to the opening of Cheers midway through in a reenactment of the incident before resuming the second half that didn't get aired.
In the Cheers episode "Woody For Hire, Norman Meets the Apes" Woody shows and tells everyone how he was an extra on Boston based drama Spenser: For Hire. In the season 4 episode of Seinfeld titled "The Pitch", Jerry and George are presenting their idea for a sitcom to NBC executives. George is unhappy with their offer and feels that he deserves the same salary as Ted Danson which he claims was $800,000 per episode, being that Cheers is also an NBC show. Danson's reported salary was actually $250,000 per episode. At this point Cheers was in its 10th season and Ted Danson had won an Emmy and a Golden Globe the year before.
In the seventh episode of the second season of How I Met Your Mother, a coffee shop barista mistakenly hears Barney's name as "Swarley" and writes it on his cup. This leads to a running gag in which everyone mercilessly refers to Barney as "Swarley" despite his protests, which culminates in everyone in McClaren's bar shouting "Swarley" when he enters and playing the Cheers theme song. The credits are then shown in the "Cheers" style. In the season seven episode, In Tailgate, Ted and Barney are outraged with the price to get into MacLaren's on New Year's Eve, so they offer for everyone to come upstairs. In the apartment, there is a puzzles sign that is designed to parody Cheers. Ted and Barney employ Kevin as their bartender, and they invent a theme song which also parodies the Cheers theme song.
In the 2004 video game Tony Hawk's Underground 2, "Jeers" is set in the Boston map, with the typeface referencing the Cheers logo. It is located down a set of stairs, and when near the front door, there is bar chatter coming from inside.
In the 2015 video game Fallout 4, which is set in Boston, there is a bar named Prost Bar near Boston Common that, when entered, is an almost exact replica of the bar featured on the series. It includes two dead bodies sitting at the end of the bar, with one of them wearing a mail carrier's uniform, a direct reference to regular barfly Cliff Clavin.
In the season 2 finale of the NBC sitcom The Good Place, Ted Danson's character Michael appears as a bartender while wearing a blue plaid button-down, in a clear homage to Danson's character in Cheers.
In September 2011, Plural Entertainment debuted a remake of the series on Spanish television, also titled Cheers. Set at an Irish pub, it starred Alberto San Juan as Nicolás "Nico" Arnedo, the equivalent of Sam Malone on the original series. It also used the original theme song, rerecorded in Spanish by Dani Martín, under the title "Donde la gente se divierte."
In December 2012, The Irish Film and Television Network announced that casting was underway on an Irish-language version of Cheers produced by production company Sideline. The new show, tentatively titled Teach Seán, would air on Ireland's TG4 and features a main character who, like Sam Malone, is a bar owner, a retired athlete, and a recovering alcoholic. However, because of being set in Ireland, the barman is a "former hurling star" rather than an ex-baseball player. As of August 2019, the Irish remake has not occurred.
On September 9, 2016, a stage adaptation called Cheers: Live on Stage opened at the Shubert Theatre in Boston. Comprising pieces of the original TV series, the play was adapted by Erik Forrest Jackson. It was produced by Troika/Stageworks. The director was Matt Lenz. It starred Grayson Powell as Sam Malone, Jillian Louis as Diane Chambers, Barry Pearl as Ernie "Coach" Pantusso, Sarah Sirotta as Carla Tortelli, Paul Vogt as Norm Peterson, and Buzz Roddy as Cliff Clavin. The production was scheduled to tour through 2017, but was cancelled in 2016. | [

] | Cheers is an American sitcom television series that ran on NBC from 1982 to 1993, with a total of 275 22-26 minute episodes across 11 seasons. The show was produced by Charles/Burrows/Charles Productions in association with Paramount Network Television and was created by the team of James Burrows and Glen and Les Charles. The show is set in the titular bar in Boston, where a group of locals meet to drink, relax, socialize and hide from their day to day issues. At the center of the show is the bar's owner and head bartender, Sam Malone, who is a womanizing former relief pitcher for the Boston Red Sox. The show's ensemble cast introduced in the pilot episode are waitresses Diane Chambers and Carla Tortelli, second bartender Coach Ernie Pantusso, and regular customers Norm Peterson and Cliff Clavin. Later main characters of the show also include Frasier Crane, Woody Boyd, Lilith Sternin, and Rebecca Howe. After premiering in 1982, it was nearly canceled during its first season when it ranked almost last in ratings for its premiere. However, Cheers eventually became a Nielsen ratings juggernaut in the United States, earning a top-10 rating during eight of its 11 seasons, including one season at number one. The show spent most of its run on NBC's Thursday night "Must See TV" lineup. Its widely watched series finale in 1993 became the most watched single TV episode of the 1990s, and the show's 275 episodes have been successfully syndicated worldwide. Nominated for Outstanding Comedy Series for all 11 of its seasons on the air, it earned 28 Primetime Emmy Awards from a record of 117 nominations. During its run, Cheers became one of the most popular series in history and received critical acclaim from its start to its end. In 1997, the episodes "Thanksgiving Orphans" and "Home Is the Sailor", aired originally in 1987, were respectively ranked No. 7 and No. 45 on TV Guide's 100 Greatest Episodes of All Time. Its series finale was watched by an estimated 93 million viewers, almost 40% of the US population at the time. The series also produced three spin-offs: The Tortellis, Wings, and Frasier; and a Spanish remake. In 2002, Cheers was ranked No. 18 on TV Guide's 50 Greatest TV Shows of All Time. In 2013, the Writers Guild of America ranked it as the eighth-best-written TV series and TV Guide ranked it No. 11 on their list of the 60 greatest shows. | 2001-07-26T23:18:46Z | 2023-12-29T23:53:06Z | [

5,909 | Counterpoint | In music, counterpoint is the relationship between two or more musical lines (or voices) which are harmonically interdependent yet independent in rhythm and melodic contour. It has been most commonly identified in the European classical tradition, strongly developing during the Renaissance and in much of the common practice period, especially in the Baroque period. The term originates from the Latin punctus contra punctum meaning "point against point", i.e. "note against note".
In Western pedagogy, counterpoint is taught through a system of species (see below).
There are several different forms of counterpoint, including imitative counterpoint and free counterpoint. Imitative counterpoint involves the repetition of a main melodic idea across different vocal parts, with or without variation. Compositions written in free counterpoint often incorporate non-traditional harmonies and chords, chromaticism and dissonance.
The term "counterpoint" has been used to designate a voice or even an entire composition. Counterpoint focuses on melodic interaction—only secondarily on the harmonies produced by that interaction. In the words of John Rahn:
It is hard to write a beautiful song. It is harder to write several individually beautiful songs that, when sung simultaneously, sound as a more beautiful polyphonic whole. The internal structures that create each of the voices separately must contribute to the emergent structure of the polyphony, which in turn must reinforce and comment on the structures of the individual voices. The way that is accomplished in detail is ... 'counterpoint'.
Work initiated by Guerino Mazzola (born 1947) has given counterpoint theory a mathematical foundation. In particular, Mazzola's model gives a structural (and not psychological) foundation of forbidden parallels of fifths and the dissonant fourth. Octavio Agustin has extended the model to microtonal contexts.
In counterpoint, the functional independence of voices is the prime concern. The violation of this principle leads to special effects, which are avoided in counterpoint. In organ registers, certain interval combinations and chords are activated by a single key so that playing a melody results in parallel voice leading. These voices, losing independence, are fused into one and the parallel chords are perceived as single tones with a new timbre. This effect is also used in orchestral arrangements; for instance, in Ravel’s Bolero #5 the parallel parts of flutes, horn and celesta resemble the sound of an electric organ. In counterpoint, parallel voices are prohibited because they violate the homogeneity of musical texture when independent voices occasionally disappear turning into a new timbre quality and vice versa.
Some examples of related compositional techniques include: the round (familiar in folk traditions), the canon, and perhaps the most complex contrapuntal convention: the fugue. All of these are examples of imitative counterpoint.
There are many examples of song melodies that are harmonically interdependent yet independent in rhythm and melodic contour. For example, "Frère Jacques" and "Three Blind Mice" combine euphoniously when sung together. A number of popular songs that share the same chord progression can also be sung together as counterpoint. A well-known pair of examples is "My Way" combined with "Life on Mars".
Johann Sebastian Bach is revered as one of the greatest masters of counterpoint. For example the harmony implied in opening subject of the Fugue in G sharp minor from Book II of the Well-tempered Clavier is heard anew in a subtle way when a second voice is added. “The counterpoint in bars 5-8… sheds an unexpected light on the tonality of the Subject.”:
Bach's 3-part Invention in F minor combines three independent melodies:
According to pianist András Schiff, Bach's counterpoint influenced the composing of both Mozart and Beethoven. In the development section of the opening movement of Beethoven's Piano Sonata in E minor, Beethoven demonstrates this influence by adding "a wonderful counterpoint" to one of the main themes.
A further example of fluid counterpoint in late Beethoven may be found in the first orchestral variation on the "Ode to Joy" theme in the last movement of Beethoven's Symphony No. 9, bars 116–123. The famous theme is heard on the violas and cellos, while "the basses add a bass-line whose sheer unpredictability gives the impression that it is being spontaneously improvised. Meantime a solo bassoon adds a counterpoint that has a similarly impromptu quality."
In the Prelude to Richard Wagner's opera Die Meistersinger von Nürnberg, three themes from the opera are combined simultaneously. According to Gordon Jacob, "This is universally and justly acclaimed as an extraordinary feat of virtuosity." However, Donald Tovey points out that here "the combination of themes ... unlike classical counterpoint, really do not of themselves combine into complete or euphonious harmony."
One spectacular example of 5-voice counterpoint can be found in the finale to Mozart's Symphony No 41 ("Jupiter" Symphony). Here five tunes combine simultaneously in "a rich tapestry of dialogue":
See also Invertible counterpoint.
Species counterpoint was developed as a pedagogical tool in which students progress through several "species" of increasing complexity, with a very simple part that remains constant known as the cantus firmus (Latin for "fixed melody"). Species counterpoint generally offers less freedom to the composer than other types of counterpoint and therefore is called a "strict" counterpoint. The student gradually attains the ability to write free counterpoint (that is, less rigorously constrained counterpoint, usually without a cantus firmus) according to the given rules at the time. The idea is at least as old as 1532, when Giovanni Maria Lanfranco described a similar concept in his Scintille di musica (Brescia, 1533). The 16th-century Venetian theorist Zarlino elaborated on the idea in his influential Le institutioni harmoniche, and it was first presented in a codified form in 1619 by Lodovico Zacconi in his Prattica di musica. Zacconi, unlike later theorists, included a few extra contrapuntal techniques, such as invertible counterpoint.
In 1725 Johann Joseph Fux published Gradus ad Parnassum (Steps to Parnassus), in which he described five species:
A succession of later theorists quite closely imitated Fux's seminal work, often with some small and idiosyncratic modifications in the rules. Many of Fux's rules concerning the purely linear construction of melodies have their origin in solfeggi. Concerning the common practice era, alterations to the melodic rules were introduced to enable the function of certain harmonic forms. The combination of these melodies produced the basic harmonic structure, the figured bass.
The following rules apply to melodic writing in each species, for each part:
And, in all species, the following rules govern the combination of the parts:
In first species counterpoint, each note in every added part (parts being also referred to as lines or voices) sounds against one note in the cantus firmus. Notes in all parts are sounded simultaneously, and move against each other simultaneously. Since all notes in First species counterpoint are whole notes, rhythmic independence is not available.
In the present context, a "step" is a melodic interval of a half or whole step. A "skip" is an interval of a third or fourth. (See Steps and skips.) An interval of a fifth or larger is referred to as a "leap".
A few further rules given by Fux, by study of the Palestrina style, and usually given in the works of later counterpoint pedagogues, are as follows.
In the adjacent example in two parts, the cantus firmus is the lower part. (The same cantus firmus is used for later examples also. Each is in the Dorian mode.)
In second species counterpoint, two notes in each of the added parts work against each longer note in the given part.
Additional considerations in second species counterpoint are as follows, and are in addition to the considerations for first species:
In third species counterpoint, four (or three, etc.) notes move against each longer note in the given part.
Three special figures are introduced into third species and later added to fifth species, and ultimately outside the restrictions of species writing. There are three figures to consider: The nota cambiata, double neighbor tones, and double passing tones.
Double neighbor tones: the figure is prolonged over four beats and allows special dissonances. The upper and lower tones are prepared on beat 1 and resolved on beat 4. The fifth note or downbeat of the next measure should move by step in the same direction as the last two notes of the double neighbor figure. Lastly a double passing tone allows two dissonant passing tones in a row. The figure would consist of 4 notes moving in the same direction by step. The two notes that allow dissonance would be beat 2 and 3 or 3 and 4. The dissonant interval of a fourth would proceed into a diminished fifth and the next note would resolve at the interval of a sixth.
In fourth species counterpoint, some notes are sustained or suspended in an added part while notes move against them in the given part, often creating a dissonance on the beat, followed by the suspended note then changing (and "catching up") to create a subsequent consonance with the note in the given part as it continues to sound. As before, fourth species counterpoint is called expanded when the added-part notes vary in length among themselves. The technique requires chains of notes sustained across the boundaries determined by beat, and so creates syncopation. Also, it is important to note that a dissonant interval is allowed on beat 1 because of the syncopation created by the suspension. While it is not incorrect to start with a half note, it is also common to start 4th species with a half rest.
Short example of "fourth species" counterpoint
In fifth species counterpoint, sometimes called florid counterpoint, the other four species of counterpoint are combined within the added parts. In the example, the first and second bars are second species, the third bar is third species, the fourth and fifth bars are third and embellished fourth species, and the final bar is first species. In florid counterpoint it is important that no one species dominates the composition.
Short example of "Florid" counterpoint
Since the Renaissance period in European music, much contrapuntal music has been written in imitative counterpoint. In imitative counterpoint, two or more voices enter at different times, and (especially when entering) each voice repeats some version of the same melodic element. The fantasia, the ricercar, and later, the canon and fugue (the contrapuntal form par excellence) all feature imitative counterpoint, which also frequently appears in choral works such as motets and madrigals. Imitative counterpoint spawned a number of devices, including:
Broadly speaking, due to the development of harmony, from the Baroque period on, most contrapuntal compositions were written in the style of free counterpoint. This means that the general focus of the composer had shifted away from how the intervals of added melodies related to a cantus firmus, and more toward how they related to each other.
Nonetheless, according to Kent Kennan: "....actual teaching in that fashion (free counterpoint) did not become widespread until the late nineteenth century." Young composers of the eighteenth and nineteenth centuries, such as Mozart, Beethoven, and Schumann, were still educated in the style of "strict" counterpoint, but in practice, they would look for ways to expand on the traditional concepts of the subject.
Main features of free counterpoint:
Linear counterpoint is "a purely horizontal technique in which the integrity of the individual melodic lines is not sacrificed to harmonic considerations. "Its distinctive feature is rather the concept of melody, which served as the starting-point for the adherents of the 'new objectivity' when they set up linear counterpoint as an anti-type to the Romantic harmony." The voice parts move freely, irrespective of the effects their combined motions may create." In other words, either "the domination of the horizontal (linear) aspects over the vertical" is featured or the "harmonic control of lines is rejected."
Associated with neoclassicism, the technique was first used in Igor Stravinsky's Octet (1923), inspired by J. S. Bach and Giovanni Palestrina. However, according to Knud Jeppesen: "Bach's and Palestrina's points of departure are antipodal. Palestrina starts out from lines and arrives at chords; Bach's music grows out of an ideally harmonic background, against which the voices develop with a bold independence that is often breath-taking."
According to Cunningham, linear harmony is "a frequent approach in the 20th century...[in which lines] are combined with almost careless abandon in the hopes that new 'chords' and 'progressions'...will result." It is possible with "any kind of line, diatonic or duodecuple".
Dissonant counterpoint was originally theorized by Charles Seeger as "at first purely a school-room discipline," consisting of species counterpoint but with all the traditional rules reversed. First species counterpoint must be all dissonances, establishing "dissonance, rather than consonance, as the rule," and consonances are "resolved" through a skip, not step. He wrote that "the effect of this discipline" was "one of purification". Other aspects of composition, such as rhythm, could be "dissonated" by applying the same principle.
Seeger was not the first to employ dissonant counterpoint, but was the first to theorize and promote it. Other composers who have used dissonant counterpoint, if not in the exact manner prescribed by Charles Seeger, include Johanna Beyer, John Cage, Ruth Crawford-Seeger, Vivian Fine, Carl Ruggles, Henry Cowell, Carlos Chávez, John J. Becker, Henry Brant, Lou Harrison, Wallingford Riegger, and Frank Wigglesworth.

] | In music, counterpoint is the relationship between two or more musical lines which are harmonically interdependent yet independent in rhythm and melodic contour. It has been most commonly identified in the European classical tradition, strongly developing during the Renaissance and in much of the common practice period, especially in the Baroque period. The term originates from the Latin punctus contra punctum meaning "point against point", i.e. "note against note". In Western pedagogy, counterpoint is taught through a system of species. There are several different forms of counterpoint, including imitative counterpoint and free counterpoint. Imitative counterpoint involves the repetition of a main melodic idea across different vocal parts, with or without variation. Compositions written in free counterpoint often incorporate non-traditional harmonies and chords, chromaticism and dissonance. | 2001-07-27T00:03:53Z | 2023-12-25T09:02:07Z | [

5,910 | Cyanide | In chemistry, a cyanide (from Greek kyanos 'dark blue') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.
In inorganic cyanides, the cyanide group is present as the cyanide anion C≡N. This anion is extremely poisonous. Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts.
Organic cyanides are usually called nitriles. In nitriles, the −C≡N group is linked by a single covalent bond to carbon. For example, in acetonitrile (CH3−C≡N), the cyanide group is bonded to methyl (−CH3). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus toxic.
The cyanide ion C≡N is isoelectronic with carbon monoxide C≡O and with molecular nitrogen N≡N. A triple bond exists between C and N. The negative charge is concentrated on carbon C.
Cyanides are produced by certain bacteria, fungi, and algae. It is an antifeedant in a number of plants. Cyanides are found in substantial amounts in certain seeds and fruit stones, e.g., those of bitter almonds, apricots, apples, and peaches. Chemical compounds that can release cyanide are known as cyanogenic compounds. In plants, cyanides are usually bound to sugar molecules in the form of cyanogenic glycosides and defend the plant against herbivores. Cassava roots (also called manioc), an important potato-like food grown in tropical countries (and the base from which tapioca is made), also contain cyanogenic glycosides.
The Madagascar bamboo Cathariostachys madagascariensis produces cyanide as a deterrent to grazing. In response, the golden bamboo lemur, which eats the bamboo, has developed a high tolerance to cyanide.
The hydrogenase enzymes contain cyanide ligands attached to iron in their active sites. The biosynthesis of cyanide in the NiFe hydrogenases proceeds from carbamoyl phosphate, which converts to cysteinyl thiocyanate, the CN donor.
The cyanide radical •CN has been identified in interstellar space. Cyanogen, (CN)2, is used to measure the temperature of interstellar gas clouds.
Hydrogen cyanide is produced by the combustion or pyrolysis of certain materials under oxygen-deficient conditions. For example, it can be detected in the exhaust of internal combustion engines and tobacco smoke. Certain plastics, especially those derived from acrylonitrile, release hydrogen cyanide when heated or burnt.
In IUPAC nomenclature, organic compounds that have a −C≡N functional group are called nitriles. An example of a nitrile is acetonitrile, CH3−C≡N. Nitriles usually do not release cyanide ions. A functional group with a hydroxyl −OH and cyanide −CN bonded to the same carbon atom is called cyanohydrin (R2C(OH)CN). Unlike nitriles, cyanohydrins do release poisonous hydrogen cyanide.
Cyanide is basic. The pKa of hydrogen cyanide is 9.21. Thus, addition of acids stronger than hydrogen cyanide to solutions of cyanide salts releases hydrogen cyanide.
Cyanide is unstable in water, but the reaction is slow until about 170 °C. It undergoes hydrolysis to give ammonia and formate, which are far less toxic than cyanide:
Cyanide hydrolase is an enzyme that catalyzes this reaction.
Because of the cyanide anion's high nucleophilicity, cyano groups are readily introduced into organic molecules by displacement of a halide group (e.g., the chloride on methyl chloride). In general, organic cyanides are called nitriles. In organic synthesis, cyanide is a C-1 synthon; i.e., it can be used to lengthen a carbon chain by one, while retaining the ability to be functionalized.
The cyanide ion is a reductant and is oxidized by strong oxidizing agents such as molecular chlorine (Cl2), hypochlorite (ClO), and hydrogen peroxide (H2O2). These oxidizers are used to destroy cyanides in effluents from gold mining.
The cyanide anion reacts with transition metals to form M-CN bonds. This reaction is the basis of cyanide's toxicity. The high affinities of metals for this anion can be attributed to its negative charge, compactness, and ability to engage in π-bonding.
Among the most important cyanide coordination compounds are the potassium ferrocyanide and the pigment Prussian blue, which are both essentially nontoxic due to the tight binding of the cyanides to a central iron atom. Prussian blue was first accidentally made around 1706, by heating substances containing iron and carbon and nitrogen, and other cyanides made subsequently (and named after it). Among its many uses, Prussian blue gives the blue color to blueprints, bluing, and cyanotypes.
The principal process used to manufacture cyanides is the Andrussow process in which gaseous hydrogen cyanide is produced from methane and ammonia in the presence of oxygen and a platinum catalyst.
Sodium cyanide, the precursor to most cyanides, is produced by treating hydrogen cyanide with sodium hydroxide:
Many cyanides are highly toxic. The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa3), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic cells. It attaches to the iron within this protein. The binding of cyanide to this enzyme prevents transport of electrons from cytochrome c to oxygen. As a result, the electron transport chain is disrupted, meaning that the cell can no longer aerobically produce ATP for energy. Tissues that depend highly on aerobic respiration, such as the central nervous system and the heart, are particularly affected. This is an example of histotoxic hypoxia.
The most hazardous compound is hydrogen cyanide, which is a gas and kills by inhalation. For this reason, an air respirator supplied by an external oxygen source must be worn when working with hydrogen cyanide. Hydrogen cyanide is produced by adding acid to a solution containing a cyanide salt. Alkaline solutions of cyanide are safer to use because they do not evolve hydrogen cyanide gas. Hydrogen cyanide may be produced in the combustion of polyurethanes; for this reason, polyurethanes are not recommended for use in domestic and aircraft furniture. Oral ingestion of a small quantity of solid cyanide or a cyanide solution of as little as 200 mg, or exposure to airborne cyanide of 270 ppm, is sufficient to cause death within minutes.
Organic nitriles do not readily release cyanide ions, and so have low toxicities. By contrast, compounds such as trimethylsilyl cyanide (CH3)3SiCN readily release HCN or the cyanide ion upon contact with water.
Hydroxocobalamin reacts with cyanide to form cyanocobalamin, which can be safely eliminated by the kidneys. This method has the advantage of avoiding the formation of methemoglobin (see below). This antidote kit is sold under the brand name Cyanokit and was approved by the U.S. FDA in 2006.
An older cyanide antidote kit included administration of three substances: amyl nitrite pearls (administered by inhalation), sodium nitrite, and sodium thiosulfate. The goal of the antidote was to generate a large pool of ferric iron (Fe) to compete for cyanide with cytochrome a3 (so that cyanide will bind to the antidote rather than the enzyme). The nitrites oxidize hemoglobin to methemoglobin, which competes with cytochrome oxidase for the cyanide ion. Cyanmethemoglobin is formed and the cytochrome oxidase enzyme is restored. The major mechanism to remove the cyanide from the body is by enzymatic conversion to thiocyanate by the mitochondrial enzyme rhodanese. Thiocyanate is a relatively non-toxic molecule and is excreted by the kidneys. To accelerate this detoxification, sodium thiosulfate is administered to provide a sulfur donor for rhodanese, needed in order to produce thiocyanate.
Minimum risk levels (MRLs) may not protect for delayed health effects or health effects acquired following repeated sublethal exposure, such as hypersensitivity, asthma, or bronchitis. MRLs may be revised after sufficient data accumulates.
Cyanide is mainly produced for the mining of silver and gold: It helps dissolve these metals allowing separation from the other solids. In the cyanide process, finely ground high-grade ore is mixed with the cyanide (at a ratio of about 1:500 parts NaCN to ore); low-grade ores are stacked into heaps and sprayed with a cyanide solution (at a ratio of about 1:1000 parts NaCN to ore). The precious metals are complexed by the cyanide anions to form soluble derivatives, e.g., [Ag(CN)2] (dicyanoargentate(I)) and [Au(CN)2] (dicyanoaurate(I)). Silver is less "noble" than gold and often occurs as the sulfide, in which case redox is not invoked (no O2 is required). Instead, a displacement reaction occurs:
The "pregnant liquor" containing these ions is separated from the solids, which are discarded to a tailing pond or spent heap, the recoverable gold having been removed. The metal is recovered from the "pregnant solution" by reduction with zinc dust or by adsorption onto activated carbon. This process can result in environmental and health problems. A number of environmental disasters have followed the overflow of tailing ponds at gold mines. Cyanide contamination of waterways has resulted in numerous cases of human and aquatic species mortality.
Aqueous cyanide is hydrolyzed rapidly, especially in sunlight. It can mobilize some heavy metals such as mercury if present. Gold can also be associated with arsenopyrite (FeAsS), which is similar to iron pyrite (fool's gold), wherein half of the sulfur atoms are replaced by arsenic. Gold-containing arsenopyrite ores are similarly reactive toward inorganic cyanide.
The second major application of alkali metal cyanides (after mining) is in the production of CN-containing compounds, usually nitriles. Acyl cyanides are produced from acyl chlorides and cyanide. Cyanogen, cyanogen chloride, and the trimer cyanuric chloride are derived from alkali metal cyanides.
The cyanide compound sodium nitroprusside is used mainly in clinical chemistry to measure urine ketone bodies mainly as a follow-up to diabetic patients. On occasion, it is used in emergency medical situations to produce a rapid decrease in blood pressure in humans; it is also used as a vasodilator in vascular research. The cobalt in artificial vitamin B12 contains a cyanide ligand as an artifact of the purification process; this must be removed by the body before the vitamin molecule can be activated for biochemical use. During World War I, a copper cyanide compound was briefly used by Japanese physicians for the treatment of tuberculosis and leprosy.
Cyanides are illegally used to capture live fish near coral reefs for the aquarium and seafood markets. The practice is controversial, dangerous, and damaging but is driven by the lucrative exotic fish market.
Poachers in Africa have been known to use cyanide to poison waterholes, to kill elephants for their ivory.
M44 cyanide devices are used in the United States to kill coyotes and other canids. Cyanide is also used for pest control in New Zealand, particularly for possums, an introduced marsupial that threatens the conservation of native species and spreads tuberculosis amongst cattle. Possums can become bait shy but the use of pellets containing the cyanide reduces bait shyness. Cyanide has been known to kill native birds, including the endangered kiwi. Cyanide is also effective for controlling the dama wallaby, another introduced marsupial pest in New Zealand. A licence is required to store, handle and use cyanide in New Zealand.
Cyanides are used as insecticides for fumigating ships. Cyanide salts are used for killing ants, and have in some places been used as rat poison (the less toxic poison arsenic is more common).
Potassium ferrocyanide is used to achieve a blue color on cast bronze sculptures during the final finishing stage of the sculpture. On its own, it will produce a very dark shade of blue and is often mixed with other chemicals to achieve the desired tint and hue. It is applied using a torch and paint brush while wearing the standard safety equipment used for any patina application: rubber gloves, safety glasses, and a respirator. The actual amount of cyanide in the mixture varies according to the recipes used by each foundry.
Cyanide is also used in jewelry-making and certain kinds of photography such as sepia toning.
Although usually thought to be toxic, cyanide and cyanohydrins increase germination in various plant species.
Deliberate cyanide poisoning of humans has occurred many times throughout history. Common salts such as sodium cyanide are involatile but water-soluble, so are poisonous by ingestion. Hydrogen cyanide is a gas, making it more indiscriminately dangerous, however it is lighter than air and rapidly disperses up into the atmosphere, which makes it ineffective as a chemical weapon. Poisoning by hydrogen cyanide is more effective in an enclosed space, such as a gas chamber. Most significantly, hydrogen cyanide released from pellets of Zyklon-B was used extensively in the extermination camps of the Holocaust.
Because of the high stability of their complexation with iron, ferrocyanides (Sodium ferrocyanide E535, Potassium ferrocyanide E536, and Calcium ferrocyanide E538) do not decompose to lethal levels in the human body and are used in the food industry as, e.g., an anticaking agent in table salt.
Cyanide is quantified by potentiometric titration, a method widely used in gold mining. It can also be determined by titration with silver ion. Some analyses begin with an air-purge of an acidified boiling solution, sweeping the vapors into a basic absorber solution. The cyanide salt absorbed in the basic solution is then analyzed.
Because of the notorious toxicity of cyanide, many methods have been investigated. Benzidine gives a blue coloration in the presence of ferricyanide. Iron(II) sulfate added to a solution of cyanide, such as the filtrate from the sodium fusion test, gives prussian blue. A solution of para-benzoquinone in DMSO reacts with inorganic cyanide to form a cyanophenol, which is fluorescent. Illumination with a UV light gives a green/blue glow if the test is positive. | [

] | In chemistry, a cyanide is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the cyanide anion −C≡N. This anion is extremely poisonous. Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the −C≡N group is linked by a single covalent bond to carbon. For example, in acetonitrile (CH3−C≡N), the cyanide group is bonded to methyl (−CH3). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus toxic. | 2001-08-11T05:35:52Z | 2023-12-29T23:48:35Z | [

5,912 | Carbonate | A carbonate is a salt of carbonic acid (H2CO3), characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2−3. The word carbonate may also refer to a carbonate ester, an organic compound containing the carbonate group O=C(−O−)2.
The term is also used as a verb, to describe carbonation: the process of raising the concentrations of carbonate and bicarbonate ions in water to produce carbonated water and other carbonated beverages – either by the addition of carbon dioxide gas under pressure or by dissolving carbonate or bicarbonate salts into the water.
In geology and mineralogy, the term "carbonate" can refer both to carbonate minerals and carbonate rock (which is made of chiefly carbonate minerals), and both are dominated by the carbonate ion, CO2−3. Carbonate minerals are extremely varied and ubiquitous in chemically precipitated sedimentary rock. The most common are calcite or calcium carbonate, CaCO3, the chief constituent of limestone (as well as the main component of mollusc shells and coral skeletons); dolomite, a calcium-magnesium carbonate CaMg(CO3)2; and siderite, or iron(II) carbonate, FeCO3, an important iron ore. Sodium carbonate ("soda" or "natron") and potassium carbonate ("potash") have been used since antiquity for cleaning and preservation, as well as for the manufacture of glass. Carbonates are widely used in industry, such as in iron smelting, as a raw material for Portland cement and lime manufacture, in the composition of ceramic glazes, and more. New applications of alkali metal carbonates include: thermal energy storage, catalysis and electrolyte both in fuel cell technology as well as in electrosynthesis of H2O2 in aqueous media.
The carbonate ion is the simplest oxocarbon anion. It consists of one carbon atom surrounded by three oxygen atoms, in a trigonal planar arrangement, with D3h molecular symmetry. It has a molecular mass of 60.01 g/mol and carries a total formal charge of −2. It is the conjugate base of the hydrogencarbonate (bicarbonate) ion, HCO−3, which is the conjugate base of H2CO3, carbonic acid.
The Lewis structure of the carbonate ion has two (long) single bonds to negative oxygen atoms, and one short double bond to a neutral oxygen atom.
This structure is incompatible with the observed symmetry of the ion, which implies that the three bonds are the same length and that the three oxygen atoms are equivalent. As in the case of the isoelectronic nitrate ion, the symmetry can be achieved by a resonance among three structures:
This resonance can be summarized by a model with fractional bonds and delocalized charges:
Metal carbonates generally decompose on heating, liberating carbon dioxide leaving behind an oxide of the metal. This process is called calcination, after calx, the Latin name of quicklime or calcium oxide, CaO, which is obtained by roasting limestone in a lime kiln:
As illustrated by its affinity for Ca, carbonate is a ligand for many metal cations. Transition metal carbonate and bicarbonate complexes feature metal ions covalently bonded to carbonate in a variety of bonding modes.
Lithium, sodium, potassium, rubidium, caesium, and ammonium carbonates are water-soluble salts, but carbonates of 2+ and 3+ ions are often poorly soluble in water. Of the insoluble metal carbonates, CaCO3 is important because, in the form of scale, it accumulates in and impedes flow through pipes. Hard water has the source of this material.
Acidification of carbonates generally liberates carbon dioxide:
Thus, scale can be removed with acid.
In solution the equilibrium between carbonate, bicarbonate, carbon dioxide and carbonic acid is sensitive to pH, temperature, and pressure. Although di- and trivalent carbonates have low solubility, bicarbonate salts are far more soluble. This difference is related to the disparate lattice energies of solids composed of mono- vs dianions, as well as mono- vs dications.
In aqueous solution, carbonate, bicarbonate, carbon dioxide, and carbonic acid participate in a dynamic equilibrium. In strongly basic conditions, the carbonate ion predominates, while in weakly basic conditions, the bicarbonate ion is prevalent. In more acid conditions, aqueous carbon dioxide, CO2(aq), is the main form, which, with water, H2O, is in equilibrium with carbonic acid – the equilibrium lies strongly towards carbon dioxide. Thus sodium carbonate is basic, sodium bicarbonate is weakly basic, while carbon dioxide itself is a weak acid.
In organic chemistry a carbonate can also refer to a functional group within a larger molecule that contains a carbon atom bound to three oxygen atoms, one of which is double bonded. These compounds are also known as organocarbonates or carbonate esters, and have the general formula ROCOOR′, or RR′CO3. Important organocarbonates include dimethyl carbonate, the cyclic compounds ethylene carbonate and propylene carbonate, and the phosgene replacement, triphosgene.
Three reversible reactions control the pH balance of blood and act as a buffer to stabilise it in the range 7.37–7.43:
Exhaled CO2(g) depletes CO2(aq), which in turn consumes H2CO3, causing the equilibrium of the first reaction to try to restore the level of carbonic acid by reacting bicarbonate with a hydrogen ion, an example of Le Châtelier's principle. The result is to make the blood more alkaline (raise pH). By the same principle, when the pH is too high, the kidneys excrete bicarbonate (HCO−3) into urine as urea via the urea cycle (or Krebs–Henseleit ornithine cycle). By removing the bicarbonate, more H is generated from carbonic acid (H2CO3), which comes from CO2(g) produced by cellular respiration.
Crucially, a similar buffer operates in the oceans. It is a major factor in climate change and the long-term carbon cycle, due to the large number of marine organisms (especially coral) which are made of calcium carbonate. Increased solubility of carbonate through increased temperatures results in lower production of marine calcite and increased concentration of atmospheric carbon dioxide. This, in turn, increases Earth temperature. The amount of CO2−3 available is on a geological scale and substantial quantities may eventually be redissolved into the sea and released to the atmosphere, increasing CO2 levels even more.
It is generally thought that the presence of carbonates in rock is strong evidence for the presence of liquid water. Recent observations of the planetary nebula NGC 6302 show evidence for carbonates in space, where aqueous alteration similar to that on Earth is unlikely. Other minerals have been proposed which would fit the observations.
Until recently carbonate deposits have not been found on Mars via remote sensing or in situ missions, even though Martian meteorites contain small amounts. Groundwater may have existed at Gusev and Meridiani Planum. | [

5,914 | Catalysis | Catalysis (/kəˈtæləsɪs/) is the increase in rate of a chemical reaction due to an added substance known as a catalyst (/ˈkætəlɪst/). Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst.
The rate increase occurs because the catalyst allows the reaction to occur by an alternative mechanism which may be much faster than the non-catalyzed mechanism. However the non-catalyzed mechanism does remain possible, so that the total rate (catalyzed plus non-catalyzed) can only increase in the presence of the catalyst and never decrease.
Catalysis may be classified as either homogeneous, whose components are dispersed in the same phase (usually gaseous or liquid) as the reactant, or heterogeneous, whose components are not in the same phase. Enzymes and other biocatalysts are often considered as a third category.
Catalysis is ubiquitous in chemical industry of all kinds. Estimates are that 90% of all commercially produced chemical products involve catalysts at some stage in the process of their manufacture.
The term "catalyst" is derived from Greek καταλύειν, kataluein, meaning "loosen" or "untie". The concept of catalysis was invented by chemist Elizabeth Fulhame, based on her novel work in oxidation-reduction experiments.
An illustrative example is the effect of catalysts to speed the decomposition of hydrogen peroxide into water and oxygen:
This reaction proceeds because the reaction products are more stable than the starting compound, but this decomposition is so slow that hydrogen peroxide solutions are commercially available. In the presence of a catalyst such as manganese dioxide this reaction proceeds much more rapidly. This effect is readily seen by the effervescence of oxygen. The catalyst is not consumed in the reaction, and may be recovered unchanged and re-used indefinitely. Accordingly, manganese dioxide is said to catalyze this reaction. In living organisms, this reaction is catalyzed by enzymes (proteins that serve as catalysts) such as catalase.
The SI derived unit for measuring the catalytic activity of a catalyst is the katal, which is quantified in moles per second. The productivity of a catalyst can be described by the turnover number (or TON) and the catalytic activity by the turn over frequency (TOF), which is the TON per time unit. The biochemical equivalent is the enzyme unit. For more information on the efficiency of enzymatic catalysis, see the article on enzymes.
In general, chemical reactions occur faster in the presence of a catalyst because the catalyst provides an alternative reaction mechanism (reaction pathway) having a lower activation energy than the non-catalyzed mechanism. In catalyzed mechanisms, the catalyst is regenerated.
As a simple example occurring in the gas phase, the reaction 2 SO2 + O2 → 2 SO3 can be catalyzed by adding nitric oxide. The reaction occurs in two steps:
The NO catalyst is regenerated. The overall rate is the rate of the slow step
An example of heterogeneous catalysis is the reaction of oxygen and hydrogen on the surface of titanium dioxide (TiO2, or titania) to produce water. Scanning tunneling microscopy showed that the molecules undergo adsorption and dissociation. The dissociated, surface-bound O and H atoms diffuse together. The intermediate reaction states are: HO2, H2O2, then H3O2 and the reaction product (water molecule dimers), after which the water molecule desorbs from the catalyst surface.
Catalysts enable pathways that differ from the uncatalyzed reactions. These pathways have lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase the reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with an energy profile diagram.
In the catalyzed elementary reaction, catalysts do not change the extent of a reaction: they have no effect on the chemical equilibrium of a reaction. The ratio of the forward and the reverse reaction rates is unaffected (see also thermodynamics). The second law of thermodynamics describes why a catalyst does not change the chemical equilibrium of a reaction. Suppose there was such a catalyst that shifted an equilibrium. Introducing the catalyst to the system would result in a reaction to move to the new equilibrium, producing energy. Production of energy is a necessary result since reactions are spontaneous only if Gibbs free energy is produced, and if there is no energy barrier, there is no need for a catalyst. Then, removing the catalyst would also result in a reaction, producing energy; i.e. the addition and its reverse process, removal, would both produce energy. Thus, a catalyst that could change the equilibrium would be a perpetual motion machine, a contradiction to the laws of thermodynamics. Thus, catalysts do not alter the equilibrium constant. (A catalyst can however change the equilibrium concentrations by reacting in a subsequent step. It is then consumed as the reaction proceeds, and thus it is also a reactant. Illustrative is the base-catalyzed hydrolysis of esters, where the produced carboxylic acid immediately reacts with the base catalyst and thus the reaction equilibrium is shifted towards hydrolysis.)
The catalyst stabilizes the transition state more than it stabilizes the starting material. It decreases the kinetic barrier by decreasing the difference in energy between starting material and the transition state. It does not change the energy difference between starting materials and products (thermodynamic barrier), or the available energy (this is provided by the environment as heat or light).
Some so-called catalysts are really precatalysts. Precatalysts convert to catalysts in the reaction. For example, Wilkinson's catalyst RhCl(PPh3)3 loses one triphenylphosphine ligand before entering the true catalytic cycle. Precatalysts are easier to store but are easily activated in situ. Because of this preactivation step, many catalytic reactions involve an induction period.
In cooperative catalysis, chemical species that improve catalytic activity are called cocatalysts or promoters.
In tandem catalysis two or more different catalysts are coupled in a one-pot reaction.
In autocatalysis, the catalyst is a product of the overall reaction, in contrast to all other types of catalysis considered in this article. The simplest example of autocatalysis is a reaction of type A + B → 2 B, in one or in several steps. The overall reaction is just A → B, so that B is a product. But since B is also a reactant, it may be present in the rate equation and affect the reaction rate. As the reaction proceeds, the concentration of B increases and can accelerate the reaction as a catalyst. In effect, the reaction accelerates itself or is autocatalyzed. An example is the hydrolysis of an ester such as aspirin to a carboxylic acid and an alcohol. In the absence of added acid catalysts, the carboxylic acid product catalyzes the hydrolysis.
A true catalyst can work in tandem with a sacrificial catalyst. The true catalyst is consumed in the elementary reaction and turned into a deactivated form. The sacrificial catalyst regenerates the true catalyst for another cycle. The sacrificial catalyst is consumed in the reaction, and as such, it is not really a catalyst, but a reagent. For example, osmium tetroxide (OsO4) is a good reagent for dihydroxylation, but it is highly toxic and expensive. In Upjohn dihydroxylation, the sacrificial catalyst N-methylmorpholine N-oxide (NMMO) regenerates OsO4, and only catalytic quantities of OsO4 are needed.
Catalysis may be classified as either homogeneous or heterogeneous. A homogeneous catalysis is one whose components are dispersed in the same phase (usually gaseous or liquid) as the reactant's molecules. A heterogeneous catalysis is one where the reaction components are not in the same phase. Enzymes and other biocatalysts are often considered as a third category. Similar mechanistic principles apply to heterogeneous, homogeneous, and biocatalysis.
Heterogeneous catalysts act in a different phase than the reactants. Most heterogeneous catalysts are solids that act on substrates in a liquid or gaseous reaction mixture. Important heterogeneous catalysts include zeolites, alumina, higher-order oxides, graphitic carbon, transition metal oxides, metals such as Raney nickel for hydrogenation, and vanadium(V) oxide for oxidation of sulfur dioxide into sulfur trioxide by the contact process.
Diverse mechanisms for reactions on surfaces are known, depending on how the adsorption takes place (Langmuir-Hinshelwood, Eley-Rideal, and Mars-van Krevelen). The total surface area of a solid has an important effect on the reaction rate. The smaller the catalyst particle size, the larger the surface area for a given mass of particles.
A heterogeneous catalyst has active sites, which are the atoms or crystal faces where the substrate actually binds. Active sites are atoms but are often described as a facet (edge, surface, step, etc) of a solid. Most of the volume but also most of the surface of a heterogeneous catalyst may be catalytically inactive. Finding out the nature of the active site is technically challenging.
For example, the catalyst for the Haber process for the synthesis of ammonia from nitrogen and hydrogen is often described as iron. But detailed studies and many optimizations have led to catalysts that are mixtures of iron-potassium-calcium-aluminum-oxide. The reacting gases adsorb onto active sites on the iron particles. Once physically adsorbed, the reagents partially or wholly dissociate and form new bonds. In this way the particularly strong triple bond in nitrogen is broken, which would be extremely uncommon in the gas phase due to its high activation energy. Thus, the activation energy of the overall reaction is lowered, and the rate of reaction increases. Another place where a heterogeneous catalyst is applied is in the oxidation of sulfur dioxide on vanadium(V) oxide for the production of sulfuric acid. Many heterogeneous catalysts are in fact nanomaterials.
Heterogeneous catalysts are typically "supported," which means that the catalyst is dispersed on a second material that enhances the effectiveness or minimizes its cost. Supports prevent or minimize agglomeration and sintering of small catalyst particles, exposing more surface area, thus catalysts have a higher specific activity (per gram) on support. Sometimes the support is merely a surface on which the catalyst is spread to increase the surface area. More often, the support and the catalyst interact, affecting the catalytic reaction. Supports can also be used in nanoparticle synthesis by providing sites for individual molecules of catalyst to chemically bind. Supports are porous materials with a high surface area, most commonly alumina, zeolites or various kinds of activated carbon. Specialized supports include silicon dioxide, titanium dioxide, calcium carbonate, and barium sulfate.
In the context of electrochemistry, specifically in fuel cell engineering, various metal-containing catalysts are used to enhance the rates of the half reactions that comprise the fuel cell. One common type of fuel cell electrocatalyst is based upon nanoparticles of platinum that are supported on slightly larger carbon particles. When in contact with one of the electrodes in a fuel cell, this platinum increases the rate of oxygen reduction either to water or to hydroxide or hydrogen peroxide.
Homogeneous catalysts function in the same phase as the reactants. Typically homogeneous catalysts are dissolved in a solvent with the substrates. One example of homogeneous catalysis involves the influence of H on the esterification of carboxylic acids, such as the formation of methyl acetate from acetic acid and methanol. High-volume processes requiring a homogeneous catalyst include hydroformylation, hydrosilylation, hydrocyanation. For inorganic chemists, homogeneous catalysis is often synonymous with organometallic catalysts. Many homogeneous catalysts are however not organometallic, illustrated by the use of cobalt salts that catalyze the oxidation of p-xylene to terephthalic acid.
Whereas transition metals sometimes attract most of the attention in the study of catalysis, small organic molecules without metals can also exhibit catalytic properties, as is apparent from the fact that many enzymes lack transition metals. Typically, organic catalysts require a higher loading (amount of catalyst per unit amount of reactant, expressed in mol% amount of substance) than transition metal(-ion)-based catalysts, but these catalysts are usually commercially available in bulk, helping to lower costs. In the early 2000s, these organocatalysts were considered "new generation" and are competitive to traditional metal(-ion)-containing catalysts. Organocatalysts are supposed to operate akin to metal-free enzymes utilizing, e.g., non-covalent interactions such as hydrogen bonding. The discipline organocatalysis is divided into the application of covalent (e.g., proline, DMAP) and non-covalent (e.g., thiourea organocatalysis) organocatalysts referring to the preferred catalyst-substrate binding and interaction, respectively. The Nobel Prize in Chemistry 2021 was awarded jointly to Benjamin List and David W.C. MacMillan "for the development of asymmetric organocatalysis."
Photocatalysis is the phenomenon where the catalyst can receive light to generate an excited state that effect redox reactions. Singlet oxygen is usually produced by photocatalysis. Photocatalysts are components of dye-sensitized solar cells.
In biology, enzymes are protein-based catalysts in metabolism and catabolism. Most biocatalysts are enzymes, but other non-protein-based classes of biomolecules also exhibit catalytic properties including ribozymes, and synthetic deoxyribozymes.
Biocatalysts can be thought of as an intermediate between homogeneous and heterogeneous catalysts, although strictly speaking soluble enzymes are homogeneous catalysts and membrane-bound enzymes are heterogeneous. Several factors affect the activity of enzymes (and other catalysts) including temperature, pH, the concentration of enzymes, substrate, and products. A particularly important reagent in enzymatic reactions is water, which is the product of many bond-forming reactions and a reactant in many bond-breaking processes.
In biocatalysis, enzymes are employed to prepare many commodity chemicals including high-fructose corn syrup and acrylamide.
Some monoclonal antibodies whose binding target is a stable molecule that resembles the transition state of a chemical reaction can function as weak catalysts for that chemical reaction by lowering its activation energy. Such catalytic antibodies are sometimes called "abzymes".
Estimates are that 90% of all commercially produced chemical products involve catalysts at some stage in the process of their manufacture. In 2005, catalytic processes generated about $900 billion in products worldwide. Catalysis is so pervasive that subareas are not readily classified. Some areas of particular concentration are surveyed below.
Petroleum refining makes intensive use of catalysis for alkylation, catalytic cracking (breaking long-chain hydrocarbons into smaller pieces), naphtha reforming and steam reforming (conversion of hydrocarbons into synthesis gas). Even the exhaust from the burning of fossil fuels is treated via catalysis: Catalytic converters, typically composed of platinum and rhodium, break down some of the more harmful byproducts of automobile exhaust.
With regard to synthetic fuels, an old but still important process is the Fischer-Tropsch synthesis of hydrocarbons from synthesis gas, which itself is processed via water-gas shift reactions, catalyzed by iron. The Sabatier reaction produces methane from carbon dioxide and hydrogen. Biodiesel and related biofuels require processing via both inorganic and biocatalysts.
Fuel cells rely on catalysts for both the anodic and cathodic reactions.
Catalytic heaters generate flameless heat from a supply of combustible fuel.
Some of the largest-scale chemicals are produced via catalytic oxidation, often using oxygen. Examples include nitric acid (from ammonia), sulfuric acid (from sulfur dioxide to sulfur trioxide by the contact process), terephthalic acid from p-xylene, acrylic acid from propylene or propane and acrylonitrile from propane and ammonia.
The production of ammonia is one of the largest-scale and most energy-intensive processes. In the Haber process nitrogen is combined with hydrogen over an iron oxide catalyst. Methanol is prepared from carbon monoxide or carbon dioxide but using copper-zinc catalysts.
Bulk polymers derived from ethylene and propylene are often prepared via Ziegler-Natta catalysis. Polyesters, polyamides, and isocyanates are derived via acid-base catalysis.
Most carbonylation processes require metal catalysts, examples include the Monsanto acetic acid process and hydroformylation.
Many fine chemicals are prepared via catalysis; methods include those of heavy industry as well as more specialized processes that would be prohibitively expensive on a large scale. Examples include the Heck reaction, and Friedel–Crafts reactions. Because most bioactive compounds are chiral, many pharmaceuticals are produced by enantioselective catalysis (catalytic asymmetric synthesis). (R)-1,2-Propandiol, the precursor to the antibacterial levofloxacin, can be synthesized efficiently from hydroxyacetone by using catalysts based on BINAP-ruthenium complexes, in Noyori asymmetric hydrogenation:
One of the most obvious applications of catalysis is the hydrogenation (reaction with hydrogen gas) of fats using nickel catalyst to produce margarine. Many other foodstuffs are prepared via biocatalysis (see below).
Catalysis affects the environment by increasing the efficiency of industrial processes, but catalysis also plays a direct role in the environment. A notable example is the catalytic role of chlorine free radicals in the breakdown of ozone. These radicals are formed by the action of ultraviolet radiation on chlorofluorocarbons (CFCs).
The term "catalyst", broadly defined as anything that increases the rate of a process, is derived from Greek καταλύειν, meaning "to annul," or "to untie," or "to pick up". The concept of catalysis was invented by chemist Elizabeth Fulhame and described in a 1794 book, based on her novel work in oxidation–reduction reactions. The first chemical reaction in organic chemistry that knowingly used a catalyst was studied in 1811 by Gottlieb Kirchhoff, who discovered the acid-catalyzed conversion of starch to glucose. The term catalysis was later used by Jöns Jakob Berzelius in 1835 to describe reactions that are accelerated by substances that remain unchanged after the reaction. Fulhame, who predated Berzelius, did work with water as opposed to metals in her reduction experiments. Other 18th century chemists who worked in catalysis were Eilhard Mitscherlich who referred to it as contact processes, and Johann Wolfgang Döbereiner who spoke of contact action. He developed Döbereiner's lamp, a lighter based on hydrogen and a platinum sponge, which became a commercial success in the 1820s that lives on today. Humphry Davy discovered the use of platinum in catalysis. In the 1880s, Wilhelm Ostwald at Leipzig University started a systematic investigation into reactions that were catalyzed by the presence of acids and bases, and found that chemical reactions occur at finite rates and that these rates can be used to determine the strengths of acids and bases. For this work, Ostwald was awarded the 1909 Nobel Prize in Chemistry. Vladimir Ipatieff performed some of the earliest industrial scale reactions, including the discovery and commercialization of oligomerization and the development of catalysts for hydrogenation.
An added substance that lowers the rate is called a reaction inhibitor if reversible and catalyst poisons if irreversible. Promoters are substances that increase the catalytic activity, even though they are not catalysts by themselves.
Inhibitors are sometimes referred to as "negative catalysts" since they decrease the reaction rate. However the term inhibitor is preferred since they do not work by introducing a reaction path with higher activation energy; this would not lower the rate since the reaction would continue to occur by the non-catalyzed path. Instead, they act either by deactivating catalysts or by removing reaction intermediates such as free radicals. In heterogeneous catalysis, coking inhibits the catalyst, which becomes covered by polymeric side products.
The inhibitor may modify selectivity in addition to rate. For instance, in the hydrogenation of alkynes to alkenes, a palladium (Pd) catalyst partly "poisoned" with lead(II) acetate (Pb(CH3CO2)2) can be used. Without the deactivation of the catalyst, the alkene produced would be further hydrogenated to alkane.
The inhibitor can produce this effect by, e.g., selectively poisoning only certain types of active sites. Another mechanism is the modification of surface geometry. For instance, in hydrogenation operations, large planes of metal surface function as sites of hydrogenolysis catalysis while sites catalyzing hydrogenation of unsaturates are smaller. Thus, a poison that covers the surface randomly will tend to lower the number of uncontaminated large planes but leave proportionally smaller sites free, thus changing the hydrogenation vs. hydrogenolysis selectivity. Many other mechanisms are also possible.
Promoters can cover up the surface to prevent the production of a mat of coke, or even actively remove such material (e.g., rhenium on platinum in platforming). They can aid the dispersion of the catalytic material or bind to reagents. | [

"text": "In the catalyzed elementary reaction, catalysts do not change the extent of a reaction: they have no effect on the chemical equilibrium of a reaction. The ratio of the forward and the reverse reaction rates is unaffected (see also thermodynamics). The second law of thermodynamics describes why a catalyst does not change the chemical equilibrium of a reaction. Suppose there was such a catalyst that shifted an equilibrium. Introducing the catalyst to the system would result in a reaction to move to the new equilibrium, producing energy. Production of energy is a necessary result since reactions are spontaneous only if Gibbs free energy is produced, and if there is no energy barrier, there is no need for a catalyst. Then, removing the catalyst would also result in a reaction, producing energy; i.e. the addition and its reverse process, removal, would both produce energy. Thus, a catalyst that could change the equilibrium would be a perpetual motion machine, a contradiction to the laws of thermodynamics. Thus, catalysts do not alter the equilibrium constant. (A catalyst can however change the equilibrium concentrations by reacting in a subsequent step. It is then consumed as the reaction proceeds, and thus it is also a reactant. Illustrative is the base-catalyzed hydrolysis of esters, where the produced carboxylic acid immediately reacts with the base catalyst and thus the reaction equilibrium is shifted towards hydrolysis.)",

As the reaction proceeds, the concentration of B increases and can accelerate the reaction as a catalyst. In effect, the reaction accelerates itself or is autocatalyzed.

] | Catalysis is the increase in rate of a chemical reaction due to an added substance known as a catalyst. Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst. The rate increase occurs because the catalyst allows the reaction to occur by an alternative mechanism which may be much faster than the non-catalyzed mechanism. However the non-catalyzed mechanism does remain possible, so that the total rate can only increase in the presence of the catalyst and never decrease. Catalysis may be classified as either homogeneous, whose components are dispersed in the same phase as the reactant, or heterogeneous, whose components are not in the same phase. Enzymes and other biocatalysts are often considered as a third category. Catalysis is ubiquitous in chemical industry of all kinds. Estimates are that 90% of all commercially produced chemical products involve catalysts at some stage in the process of their manufacture. The term "catalyst" is derived from Greek καταλύειν, kataluein, meaning "loosen" or "untie". The concept of catalysis was invented by chemist Elizabeth Fulhame, based on her novel work in oxidation-reduction experiments. | 2001-08-15T21:08:43Z | 2023-12-22T12:51:39Z | [

5,916 | Circumference | In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure. Circumference may also refer to the circle itself, that is, the locus corresponding to the edge of a disk. The circumference of a sphere is the circumference, or length, of any one of its great circles.
The circumference of a circle is the distance around it, but if, as in many elementary treatments, distance is defined in terms of straight lines, this cannot be used as a definition. Under these circumstances, the circumference of a circle may be defined as the limit of the perimeters of inscribed regular polygons as the number of sides increases without bound. The term circumference is used when measuring physical objects, as well as when considering abstract geometric forms.
The circumference of a circle is related to one of the most important mathematical constants. This constant, pi, is represented by the Greek letter π . {\displaystyle \pi .} The first few decimal digits of the numerical value of π {\displaystyle \pi } are 3.141592653589793 ... Pi is defined as the ratio of a circle's circumference C {\displaystyle C} to its diameter d : {\displaystyle d:}
Or, equivalently, as the ratio of the circumference to twice the radius. The above formula can be rearranged to solve for the circumference:
The ratio of the circle's circumference to its radius is called the circle constant, and is equivalent to 2 π {\displaystyle 2\pi } . The value 2 π {\displaystyle 2\pi } is also the amount of radians in one turn. The use of the mathematical constant π is ubiquitous in mathematics, engineering, and science.
In Measurement of a Circle written circa 250 BCE, Archimedes showed that this ratio ( C / d , {\displaystyle C/d,} since he did not use the name π) was greater than 310/71 but less than 31/7 by calculating the perimeters of an inscribed and a circumscribed regular polygon of 96 sides. This method for approximating π was used for centuries, obtaining more accuracy by using polygons of larger and larger number of sides. The last such calculation was performed in 1630 by Christoph Grienberger who used polygons with 10 sides.
Circumference is used by some authors to denote the perimeter of an ellipse. There is no general formula for the circumference of an ellipse in terms of the semi-major and semi-minor axes of the ellipse that uses only elementary functions. However, there are approximate formulas in terms of these parameters. One such approximation, due to Euler (1773), for the canonical ellipse,

Some lower and upper bounds on the circumference of the canonical ellipse with a ≥ b {\displaystyle a\geq b} are:
Here the upper bound 2 π a {\displaystyle 2\pi a} is the circumference of a circumscribed concentric circle passing through the endpoints of the ellipse's major axis, and the lower bound 4 a 2 + b 2 {\displaystyle 4{\sqrt {a^{2}+b^{2}}}} is the perimeter of an inscribed rhombus with vertices at the endpoints of the major and minor axes.
The circumference of an ellipse can be expressed exactly in terms of the complete elliptic integral of the second kind. More precisely,

5,918 | Continuum mechanics | Continuum mechanics is a branch of mechanics that deals with the deformation of and transmission of forces through materials modeled as a continuous medium (also called a continuum) rather than as discrete particles. The French mathematician Augustin-Louis Cauchy was the first to formulate such models in the 19th century.
Continuum mechanics deals with deformable bodies, as opposed to rigid bodies. A continuum model assumes that the substance of the object completely fills the space it occupies. While ignoring the fact that matter is made of atoms, this provides a sufficiently accurate description of matter on length scales much greater than that of inter-atomic distances. The concept of a continuous medium allows for intuitive analysis of bulk matter by using differential equations that describe the behavior of such matter according to physical laws, such as mass conservation, momentum conservation, and energy conservation. Information about the specific material is expressed in constitutive relationships.
Continuum mechanics treats the physical properties of solids and fluids independently of any particular coordinate system in which they are observed. These properties are represented by tensors, which are mathematical objects with the salient property of being independent of coordinate systems. This permits definition of physical properties at any point in the continuum, according to mathematically convenient continuous functions. The theories of elasticity, plasticity and fluid mechanics are based on the concepts of continuum mechanics.
The concept of a continuum underlies the mathematical framework for studying large-scale forces and deformations in materials. Although materials are composed of discrete atoms and molecules, separated by empty space or microscopic cracks and crystallographic defects, physical phenomena can often be modeled by considering a substance distributed throughout some region of space. A continuum is a body that can be continually sub-divided into infinitesimal elements with local material properties defined at any particular point. Properties of the bulk material can therefore be described by continuous functions, and their evolution can be studied using the mathematics of calculus.
Apart from the assumption of continuity, two other independent assumptions are often employed in the study of continuum mechanics. These are homogeneity (assumption of identical properties at all locations) and isotropy (assumption of directionally invariant vector properties). If these auxiliary assumptions are not globally applicable, the material may be segregated into sections where they are applicable in order to simplify the analysis. For more complex cases, one or both of these assumptions can be dropped. In these cases, computational methods are often used to solve the differential equations describing the evolution of material properties.
An additional area of continuum mechanics comprises elastomeric foams, which exhibit a curious hyperbolic stress-strain relationship. The elastomer is a true continuum, but a homogeneous distribution of voids gives it unusual properties.
Continuum mechanics models begin by assigning a region in three-dimensional Euclidean space to the material body B {\displaystyle {\mathcal {B}}} being modeled. The points within this region are called particles or material points. Different configurations or states of the body correspond to different regions in Euclidean space. The region corresponding to the body's configuration at time t {\displaystyle t} is labeled κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} .
A particular particle within the body in a particular configuration is characterized by a position vector
where e i {\displaystyle \mathbf {e} _{i}} are the coordinate vectors in some frame of reference chosen for the problem (See figure 1). This vector can be expressed as a function of the particle position X {\displaystyle \mathbf {X} } in some reference configuration, for example the configuration at the initial time, so that
This function needs to have various properties so that the model makes physical sense. κ t ( ⋅ ) {\displaystyle \kappa _{t}(\cdot )} needs to be:
For the mathematical formulation of the model, κ t ( ⋅ ) {\displaystyle \kappa _{t}(\cdot )} is also assumed to be twice continuously differentiable, so that differential equations describing the motion may be formulated.
A solid is a deformable body that possesses shear strength, sc. a solid can support shear forces (forces parallel to the material surface on which they act). Fluids, on the other hand, do not sustain shear forces.
Following the classical dynamics of Newton and Euler, the motion of a material body is produced by the action of externally applied forces which are assumed to be of two kinds: surface forces F C {\displaystyle \mathbf {F} _{C}} and body forces F B {\displaystyle \mathbf {F} _{B}} . Thus, the total force F {\displaystyle {\mathcal {F}}} applied to a body or to a portion of the body can be expressed as:
Surface forces or contact forces, expressed as force per unit area, can act either on the bounding surface of the body, as a result of mechanical contact with other bodies, or on imaginary internal surfaces that bound portions of the body, as a result of the mechanical interaction between the parts of the body to either side of the surface (Euler-Cauchy's stress principle). When a body is acted upon by external contact forces, internal contact forces are then transmitted from point to point inside the body to balance their action, according to Newton's third law of motion of conservation of linear momentum and angular momentum (for continuous bodies these laws are called the Euler's equations of motion). The internal contact forces are related to the body's deformation through constitutive equations. The internal contact forces may be mathematically described by how they relate to the motion of the body, independent of the body's material makeup.
The distribution of internal contact forces throughout the volume of the body is assumed to be continuous. Therefore, there exists a contact force density or Cauchy traction field T ( n , x , t ) {\displaystyle \mathbf {T} (\mathbf {n} ,\mathbf {x} ,t)} that represents this distribution in a particular configuration of the body at a given time t {\displaystyle t\,\!} . It is not a vector field because it depends not only on the position x {\displaystyle \mathbf {x} } of a particular material point, but also on the local orientation of the surface element as defined by its normal vector n {\displaystyle \mathbf {n} } .
Any differential area d S {\displaystyle dS\,\!} with normal vector n {\displaystyle \mathbf {n} } of a given internal surface area S {\displaystyle S\,\!} , bounding a portion of the body, experiences a contact force d F C {\displaystyle d\mathbf {F} _{C}\,\!} arising from the contact between both portions of the body on each side of S {\displaystyle S\,\!} , and it is given by
where T ( n ) {\displaystyle \mathbf {T} ^{(\mathbf {n} )}} is the surface traction, also called stress vector, traction, or traction vector. The stress vector is a frame-indifferent vector (see Euler-Cauchy's stress principle).
The total contact force on the particular internal surface S {\displaystyle S\,\!} is then expressed as the sum (surface integral) of the contact forces on all differential surfaces d S {\displaystyle dS\,\!} :
In continuum mechanics a body is considered stress-free if the only forces present are those inter-atomic forces (ionic, metallic, and van der Waals forces) required to hold the body together and to keep its shape in the absence of all external influences, including gravitational attraction. Stresses generated during manufacture of the body to a specific configuration are also excluded when considering stresses in a body. Therefore, the stresses considered in continuum mechanics are only those produced by deformation of the body, sc. only relative changes in stress are considered, not the absolute values of stress.
Body forces are forces originating from sources outside of the body that act on the volume (or mass) of the body. Saying that body forces are due to outside sources implies that the interaction between different parts of the body (internal forces) are manifested through the contact forces alone. These forces arise from the presence of the body in force fields, e.g. gravitational field (gravitational forces) or electromagnetic field (electromagnetic forces), or from inertial forces when bodies are in motion. As the mass of a continuous body is assumed to be continuously distributed, any force originating from the mass is also continuously distributed. Thus, body forces are specified by vector fields which are assumed to be continuous over the entire volume of the body, i.e. acting on every point in it. Body forces are represented by a body force density b ( x , t ) {\displaystyle \mathbf {b} (\mathbf {x} ,t)} (per unit of mass), which is a frame-indifferent vector field.
In the case of gravitational forces, the intensity of the force depends on, or is proportional to, the mass density ρ ( x , t ) {\displaystyle \mathbf {\rho } (\mathbf {x} ,t)\,\!} of the material, and it is specified in terms of force per unit mass ( b i {\displaystyle b_{i}\,\!} ) or per unit volume ( p i {\displaystyle p_{i}\,\!} ). These two specifications are related through the material density by the equation ρ b i = p i {\displaystyle \rho b_{i}=p_{i}\,\!} . Similarly, the intensity of electromagnetic forces depends upon the strength (electric charge) of the electromagnetic field.
The total body force applied to a continuous body is expressed as
Body forces and contact forces acting on the body lead to corresponding moments of force (torques) relative to a given point. Thus, the total applied torque M {\displaystyle {\mathcal {M}}} about the origin is given by
In certain situations, not commonly considered in the analysis of the mechanical behavior of materials, it becomes necessary to include two other types of forces: these are couple stresses (surface couples, contact torques) and body moments. Couple stresses are moments per unit area applied on a surface. Body moments, or body couples, are moments per unit volume or per unit mass applied to the volume of the body. Both are important in the analysis of stress for a polarized dielectric solid under the action of an electric field, materials where the molecular structure is taken into consideration (e.g. bones), solids under the action of an external magnetic field, and the dislocation theory of metals.
Materials that exhibit body couples and couple stresses in addition to moments produced exclusively by forces are called polar materials. Non-polar materials are then those materials with only moments of forces. In the classical branches of continuum mechanics the development of the theory of stresses is based on non-polar materials.
Thus, the sum of all applied forces and torques (with respect to the origin of the coordinate system) in the body can be given by
A change in the configuration of a continuum body results in a displacement. The displacement of a body has two components: a rigid-body displacement and a deformation. A rigid-body displacement consists of a simultaneous translation and rotation of the body without changing its shape or size. Deformation implies the change in shape and/or size of the body from an initial or undeformed configuration κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} to a current or deformed configuration κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} (Figure 2).
The motion of a continuum body is a continuous time sequence of displacements. Thus, the material body will occupy different configurations at different times so that a particle occupies a series of points in space which describe a path line.
There is continuity during motion or deformation of a continuum body in the sense that:
It is convenient to identify a reference configuration or initial condition which all subsequent configurations are referenced from. The reference configuration need not be one that the body will ever occupy. Often, the configuration at t = 0 {\displaystyle t=0} is considered the reference configuration, κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} . The components X i {\displaystyle X_{i}} of the position vector X {\displaystyle \mathbf {X} } of a particle, taken with respect to the reference configuration, are called the material or reference coordinates.
When analyzing the motion or deformation of solids, or the flow of fluids, it is necessary to describe the sequence or evolution of configurations throughout time. One description for motion is made in terms of the material or referential coordinates, called material description or Lagrangian description.
In the Lagrangian description the position and physical properties of the particles are described in terms of the material or referential coordinates and time. In this case the reference configuration is the configuration at t = 0 {\displaystyle t=0} . An observer standing in the frame of reference observes the changes in the position and physical properties as the material body moves in space as time progresses. The results obtained are independent of the choice of initial time and reference configuration, κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} . This description is normally used in solid mechanics.
In the Lagrangian description, the motion of a continuum body is expressed by the mapping function χ ( ⋅ ) {\displaystyle \chi (\cdot )} (Figure 2),
which is a mapping of the initial configuration κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} onto the current configuration κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} , giving a geometrical correspondence between them, i.e. giving the position vector x = x i e i {\displaystyle \mathbf {x} =x_{i}\mathbf {e} _{i}} that a particle X {\displaystyle X} , with a position vector X {\displaystyle \mathbf {X} } in the undeformed or reference configuration κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} , will occupy in the current or deformed configuration κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} at time t {\displaystyle t} . The components x i {\displaystyle x_{i}} are called the spatial coordinates.
Physical and kinematic properties P i j … {\displaystyle P_{ij\ldots }} , i.e. thermodynamic properties and flow velocity, which describe or characterize features of the material body, are expressed as continuous functions of position and time, i.e. P i j … = P i j … ( X , t ) {\displaystyle P_{ij\ldots }=P_{ij\ldots }(\mathbf {X} ,t)} .
The material derivative of any property P i j … {\displaystyle P_{ij\ldots }} of a continuum, which may be a scalar, vector, or tensor, is the time rate of change of that property for a specific group of particles of the moving continuum body. The material derivative is also known as the substantial derivative, or comoving derivative, or convective derivative. It can be thought as the rate at which the property changes when measured by an observer traveling with that group of particles.
In the Lagrangian description, the material derivative of P i j … {\displaystyle P_{ij\ldots }} is simply the partial derivative with respect to time, and the position vector X {\displaystyle \mathbf {X} } is held constant as it does not change with time. Thus, we have
The instantaneous position x {\displaystyle \mathbf {x} } is a property of a particle, and its material derivative is the instantaneous flow velocity v {\displaystyle \mathbf {v} } of the particle. Therefore, the flow velocity field of the continuum is given by
Similarly, the acceleration field is given by
Continuity in the Lagrangian description is expressed by the spatial and temporal continuity of the mapping from the reference configuration to the current configuration of the material points. All physical quantities characterizing the continuum are described this way. In this sense, the function χ ( ⋅ ) {\displaystyle \chi (\cdot )} and P i j … ( ⋅ ) {\displaystyle P_{ij\ldots }(\cdot )} are single-valued and continuous, with continuous derivatives with respect to space and time to whatever order is required, usually to the second or third.
Continuity allows for the inverse of χ ( ⋅ ) {\displaystyle \chi (\cdot )} to trace backwards where the particle currently located at x {\displaystyle \mathbf {x} } was located in the initial or referenced configuration κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} . In this case the description of motion is made in terms of the spatial coordinates, in which case is called the spatial description or Eulerian description, i.e. the current configuration is taken as the reference configuration.
The Eulerian description, introduced by d'Alembert, focuses on the current configuration κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} , giving attention to what is occurring at a fixed point in space as time progresses, instead of giving attention to individual particles as they move through space and time. This approach is conveniently applied in the study of fluid flow where the kinematic property of greatest interest is the rate at which change is taking place rather than the shape of the body of fluid at a reference time.
Mathematically, the motion of a continuum using the Eulerian description is expressed by the mapping function
which provides a tracing of the particle which now occupies the position x {\displaystyle \mathbf {x} } in the current configuration κ t ( B ) {\displaystyle \kappa _{t}({\mathcal {B}})} to its original position X {\displaystyle \mathbf {X} } in the initial configuration κ 0 ( B ) {\displaystyle \kappa _{0}({\mathcal {B}})} .
A necessary and sufficient condition for this inverse function to exist is that the determinant of the Jacobian matrix, often referred to simply as the Jacobian, should be different from zero. Thus,
In the Eulerian description, the physical properties P i j … {\displaystyle P_{ij\ldots }} are expressed as
where the functional form of P i j … {\displaystyle P_{ij\ldots }} in the Lagrangian description is not the same as the form of p i j … {\displaystyle p_{ij\ldots }} in the Eulerian description.
The material derivative of p i j … ( x , t ) {\displaystyle p_{ij\ldots }(\mathbf {x} ,t)} , using the chain rule, is then
The first term on the right-hand side of this equation gives the local rate of change of the property p i j … ( x , t ) {\displaystyle p_{ij\ldots }(\mathbf {x} ,t)} occurring at position x {\displaystyle \mathbf {x} } . The second term of the right-hand side is the convective rate of change and expresses the contribution of the particle changing position in space (motion).
Continuity in the Eulerian description is expressed by the spatial and temporal continuity and continuous differentiability of the flow velocity field. All physical quantities are defined this way at each instant of time, in the current configuration, as a function of the vector position x {\displaystyle \mathbf {x} } .
The vector joining the positions of a particle P {\displaystyle P} in the undeformed configuration and deformed configuration is called the displacement vector u ( X , t ) = u i e i {\displaystyle \mathbf {u} (\mathbf {X} ,t)=u_{i}\mathbf {e} _{i}} , in the Lagrangian description, or U ( x , t ) = U J E J {\displaystyle \mathbf {U} (\mathbf {x} ,t)=U_{J}\mathbf {E} _{J}} , in the Eulerian description.
A displacement field is a vector field of all displacement vectors for all particles in the body, which relates the deformed configuration with the undeformed configuration. It is convenient to do the analysis of deformation or motion of a continuum body in terms of the displacement field, In general, the displacement field is expressed in terms of the material coordinates as
or in terms of the spatial coordinates as
where α J i {\displaystyle \alpha _{Ji}} are the direction cosines between the material and spatial coordinate systems with unit vectors E J {\displaystyle \mathbf {E} _{J}} and e i {\displaystyle \mathbf {e} _{i}} , respectively. Thus
and the relationship between u i {\displaystyle u_{i}} and U J {\displaystyle U_{J}} is then given by
Knowing that
then
It is common to superimpose the coordinate systems for the undeformed and deformed configurations, which results in b = 0 {\displaystyle \mathbf {b} =0} , and the direction cosines become Kronecker deltas, i.e.
Thus, we have
or in terms of the spatial coordinates as
Continuum mechanics deals with the behavior of materials that can be approximated as continuous for certain length and time scales. The equations that govern the mechanics of such materials include the balance laws for mass, momentum, and energy. Kinematic relations and constitutive equations are needed to complete the system of governing equations. Physical restrictions on the form of the constitutive relations can be applied by requiring that the second law of thermodynamics be satisfied under all conditions. In the continuum mechanics of solids, the second law of thermodynamics is satisfied if the Clausius–Duhem form of the entropy inequality is satisfied.
The balance laws express the idea that the rate of change of a quantity (mass, momentum, energy) in a volume must arise from three causes:
Let Ω {\displaystyle \Omega } be the body (an open subset of Euclidean space) and let ∂ Ω {\displaystyle \partial \Omega } be its surface (the boundary of Ω {\displaystyle \Omega } ).
Let the motion of material points in the body be described by the map
where X {\displaystyle \mathbf {X} } is the position of a point in the initial configuration and x {\displaystyle \mathbf {x} } is the location of the same point in the deformed configuration.
The deformation gradient is given by
Let f ( x , t ) {\displaystyle f(\mathbf {x} ,t)} be a physical quantity that is flowing through the body. Let g ( x , t ) {\displaystyle g(\mathbf {x} ,t)} be sources on the surface of the body and let h ( x , t ) {\displaystyle h(\mathbf {x} ,t)} be sources inside the body. Let n ( x , t ) {\displaystyle \mathbf {n} (\mathbf {x} ,t)} be the outward unit normal to the surface ∂ Ω {\displaystyle \partial \Omega } . Let v ( x , t ) {\displaystyle \mathbf {v} (\mathbf {x} ,t)} be the flow velocity of the physical particles that carry the physical quantity that is flowing. Also, let the speed at which the bounding surface ∂ Ω {\displaystyle \partial \Omega } is moving be u n {\displaystyle u_{n}} (in the direction n {\displaystyle \mathbf {n} } ).
Then, balance laws can be expressed in the general form
The functions f ( x , t ) {\displaystyle f(\mathbf {x} ,t)} , g ( x , t ) {\displaystyle g(\mathbf {x} ,t)} , and h ( x , t ) {\displaystyle h(\mathbf {x} ,t)} can be scalar valued, vector valued, or tensor valued - depending on the physical quantity that the balance equation deals with. If there are internal boundaries in the body, jump discontinuities also need to be specified in the balance laws.
If we take the Eulerian point of view, it can be shown that the balance laws of mass, momentum, and energy for a solid can be written as (assuming the source term is zero for the mass and angular momentum equations)
In the above equations ρ ( x , t ) {\displaystyle \rho (\mathbf {x} ,t)} is the mass density (current), ρ ˙ {\displaystyle {\dot {\rho }}} is the material time derivative of ρ {\displaystyle \rho } , v ( x , t ) {\displaystyle \mathbf {v} (\mathbf {x} ,t)} is the particle velocity, v ˙ {\displaystyle {\dot {\mathbf {v} }}} is the material time derivative of v {\displaystyle \mathbf {v} } , σ ( x , t ) {\displaystyle {\boldsymbol {\sigma }}(\mathbf {x} ,t)} is the Cauchy stress tensor, b ( x , t ) {\displaystyle \mathbf {b} (\mathbf {x} ,t)} is the body force density, e ( x , t ) {\displaystyle e(\mathbf {x} ,t)} is the internal energy per unit mass, e ˙ {\displaystyle {\dot {e}}} is the material time derivative of e {\displaystyle e} , q ( x , t ) {\displaystyle \mathbf {q} (\mathbf {x} ,t)} is the heat flux vector, and s ( x , t ) {\displaystyle s(\mathbf {x} ,t)} is an energy source per unit mass. The operators used are defined below.
With respect to the reference configuration (the Lagrangian point of view), the balance laws can be written as
In the above, P {\displaystyle {\boldsymbol {P}}} is the first Piola-Kirchhoff stress tensor, and ρ 0 {\displaystyle \rho _{0}} is the mass density in the reference configuration. The first Piola-Kirchhoff stress tensor is related to the Cauchy stress tensor by
We can alternatively define the nominal stress tensor N {\displaystyle {\boldsymbol {N}}} which is the transpose of the first Piola-Kirchhoff stress tensor such that
Then the balance laws become
The operators in the above equations are defined as
where v {\displaystyle \mathbf {v} } is a vector field, S {\displaystyle {\boldsymbol {S}}} is a second-order tensor field, and e i {\displaystyle \mathbf {e} _{i}} are the components of an orthonormal basis in the current configuration. Also,
where v {\displaystyle \mathbf {v} } is a vector field, S {\displaystyle {\boldsymbol {S}}} is a second-order tensor field, and E i {\displaystyle \mathbf {E} _{i}} are the components of an orthonormal basis in the reference configuration.
The inner product is defined as
The Clausius–Duhem inequality can be used to express the second law of thermodynamics for elastic-plastic materials. This inequality is a statement concerning the irreversibility of natural processes, especially when energy dissipation is involved.
Just like in the balance laws in the previous section, we assume that there is a flux of a quantity, a source of the quantity, and an internal density of the quantity per unit mass. The quantity of interest in this case is the entropy. Thus, we assume that there is an entropy flux, an entropy source, an internal mass density ρ {\displaystyle \rho } and an internal specific entropy (i.e. entropy per unit mass) η {\displaystyle \eta } in the region of interest.
Let Ω {\displaystyle \Omega } be such a region and let ∂ Ω {\displaystyle \partial \Omega } be its boundary. Then the second law of thermodynamics states that the rate of increase of η {\displaystyle \eta } in this region is greater than or equal to the sum of that supplied to Ω {\displaystyle \Omega } (as a flux or from internal sources) and the change of the internal entropy density ρ η {\displaystyle \rho \eta } due to material flowing in and out of the region.
Let ∂ Ω {\displaystyle \partial \Omega } move with a flow velocity u n {\displaystyle u_{n}} and let particles inside Ω {\displaystyle \Omega } have velocities v {\displaystyle \mathbf {v} } . Let n {\displaystyle \mathbf {n} } be the unit outward normal to the surface ∂ Ω {\displaystyle \partial \Omega } . Let ρ {\displaystyle \rho } be the density of matter in the region, q ¯ {\displaystyle {\bar {q}}} be the entropy flux at the surface, and r {\displaystyle r} be the entropy source per unit mass. Then the entropy inequality may be written as
The scalar entropy flux can be related to the vector flux at the surface by the relation q ¯ = − ψ ( x ) ⋅ n {\displaystyle {\bar {q}}=-{\boldsymbol {\psi }}(\mathbf {x} )\cdot \mathbf {n} } . Under the assumption of incrementally isothermal conditions, we have
where q {\displaystyle \mathbf {q} } is the heat flux vector, s {\displaystyle s} is an energy source per unit mass, and T {\displaystyle T} is the absolute temperature of a material point at x {\displaystyle \mathbf {x} } at time t {\displaystyle t} .
We then have the Clausius–Duhem inequality in integral form:
We can show that the entropy inequality may be written in differential form as
In terms of the Cauchy stress and the internal energy, the Clausius–Duhem inequality may be written as
The validity of the continuum assumption may be verified by a theoretical analysis, in which either some clear periodicity is identified or statistical homogeneity and ergodicity of the microstructure exist. More specifically, the continuum hypothesis hinges on the concepts of a representative elementary volume and separation of scales based on the Hill–Mandel condition. This condition provides a link between an experimentalist's and a theoretician's viewpoint on constitutive equations (linear and nonlinear elastic/inelastic or coupled fields) as well as a way of spatial and statistical averaging of the microstructure. When the separation of scales does not hold, or when one wants to establish a continuum of a finer resolution than the size of the representative volume element (RVE), a statistical volume element (SVE) is employed, which results in random continuum fields. The latter then provide a micromechanics basis for stochastic finite elements (SFE). The levels of SVE and RVE link continuum mechanics to statistical mechanics. Experimentally, the RVE can only be evaluated when the constitutive response is spatially homogenous. | [

"text": "The validity of the continuum assumption may be verified by a theoretical analysis, in which either some clear periodicity is identified or statistical homogeneity and ergodicity of the microstructure exist. More specifically, the continuum hypothesis hinges on the concepts of a representative elementary volume and separation of scales based on the Hill–Mandel condition. This condition provides a link between an experimentalist's and a theoretician's viewpoint on constitutive equations (linear and nonlinear elastic/inelastic or coupled fields) as well as a way of spatial and statistical averaging of the microstructure. When the separation of scales does not hold, or when one wants to establish a continuum of a finer resolution than the size of the representative volume element (RVE), a statistical volume element (SVE) is employed, which results in random continuum fields. The latter then provide a micromechanics basis for stochastic finite elements (SFE). The levels of SVE and RVE link continuum mechanics to statistical mechanics. Experimentally, the RVE can only be evaluated when the constitutive response is spatially homogenous.",

] | Continuum mechanics is a branch of mechanics that deals with the deformation of and transmission of forces through materials modeled as a continuous medium rather than as discrete particles. The French mathematician Augustin-Louis Cauchy was the first to formulate such models in the 19th century. Continuum mechanics deals with deformable bodies, as opposed to rigid bodies. A continuum model assumes that the substance of the object completely fills the space it occupies. While ignoring the fact that matter is made of atoms, this provides a sufficiently accurate description of matter on length scales much greater than that of inter-atomic distances. The concept of a continuous medium allows for intuitive analysis of bulk matter by using differential equations that describe the behavior of such matter according to physical laws, such as mass conservation, momentum conservation, and energy conservation. Information about the specific material is expressed in constitutive relationships. Continuum mechanics treats the physical properties of solids and fluids independently of any particular coordinate system in which they are observed. These properties are represented by tensors, which are mathematical objects with the salient property of being independent of coordinate systems. This permits definition of physical properties at any point in the continuum, according to mathematically convenient continuous functions. The theories of elasticity, plasticity and fluid mechanics are based on the concepts of continuum mechanics. | 2001-07-29T05:48:28Z | 2023-12-22T10:48:45Z | [

5,919 | Constitutional law | Constitutional law is a body of law which defines the role, powers, and structure of different entities within a state, namely, the executive, the parliament or legislature, and the judiciary; as well as the basic rights of citizens and, in federal countries such as the United States and Canada, the relationship between the central government and state, provincial, or territorial governments.
Not all nation states have codified constitutions, though all such states have a jus commune, or law of the land, that may consist of a variety of imperative and consensual rules. These may include customary law, conventions, statutory law, judge-made law, or international rules and norms. Constitutional law deals with the fundamental principles by which the government exercises its authority. In some instances, these principles grant specific powers to the government, such as the power to tax and spend for the welfare of the population. Other times, constitutional principles act to place limits on what the government can do, such as prohibiting the arrest of an individual without sufficient cause.
In most nations, such as the United States, India, and Singapore, constitutional law is based on the text of a document ratified at the time the nation came into being. Other constitutions, notably that of the United Kingdom, rely heavily on uncodified rules, as several legislative statutes and constitutional conventions, their status within constitutional law varies, and the terms of conventions are in some cases strongly contested.
Constitutional laws can be considered second order rule making or rules about making rules to exercise power. It governs the relationships between the judiciary, the legislature and the executive with the bodies under its authority. One of the key tasks of constitutions within this context is to indicate hierarchies and relationships of power. For example, in a unitary state, the constitution will vest ultimate authority in one central administration and legislature, and judiciary, though there is often a delegation of power or authority to local or municipal authorities. When a constitution establishes a federal state, it will identify the several levels of government coexisting with exclusive or shared areas of jurisdiction over lawmaking, application and enforcement. Some federal states, most notably the United States, have separate and parallel federal and state judiciaries, with each having its own hierarchy of courts with a supreme court for each state. India, on the other hand, has one judiciary divided into district courts, high courts, and the Supreme Court of India.
Human rights or civil liberties form a crucial part of a country's constitution and uphold the rights of the individual against the state. Most jurisdictions, like the United States and France, have a codified constitution, with a bill of rights. A recent example is the Charter of Fundamental Rights of the European Union which was intended to be included in the Treaty establishing a Constitution for Europe, that failed to be ratified. Perhaps the most important example is the Universal Declaration of Human Rights under the UN Charter. These are intended to ensure basic political, social and economic standards that a nation state, or intergovernmental body is obliged to provide to its citizens but many do include its governments. Canada is another instance where a codified constitution. with the Canadian Charter of Rights and Freedoms, protects human rights for people under the nation's jurisdiction.
Some countries like the United Kingdom have no entrenched document setting out fundamental rights; in those jurisdictions the constitution is composed of statute, case law and convention. A case named Entick v. Carrington is a constitutional principle deriving from the common law. John Entick's house was searched and ransacked by Sherriff Carrington. Carrington argued that a warrant from a Government minister, the Earl of Halifax was valid authority, even though there was no statutory provision or court order for it. The court, led by Lord Camden stated that,
"The great end, for which men entered into society, was to secure their property. That right is preserved sacred and incommunicable in all instances, where it has not been taken away or abridged by some public law for the good of the whole. By the laws of England, every invasion of private property, be it ever so minute, is a trespass... If no excuse can be found or produced, the silence of the books is an authority against the defendant, and the plaintiff must have judgment."
The common law and the civil law jurisdictions do not share the same constitutional law underpinnings. Common law nations, such as those in the Commonwealth as well as the United States, derive their legal systems from that of the United Kingdom, and as such place emphasis on judicial precedent, whereby consequential court rulings (especially those by higher courts) are a source of law. Civil law jurisdictions, on the other hand, place less emphasis on judicial review and only the parliament or legislature has the power to effect law. As a result, the structure of the judiciary differs significantly between the two, with common law judiciaries being adversarial and civil law judiciaries being inquisitorial. Common law judicatures consequently separate the judiciary from the prosecution, thereby establishing the courts as completely independent from both the legislature and law enforcement. Human rights law in these countries is as a result, largely built on legal precedent in the courts' interpretation of constitutional law, whereas that of civil law countries is almost exclusively composed of codified law, constitutional or otherwise.
Another main function of constitutions may be to describe the procedure by which parliaments may legislate. For instance, special majorities may be required to alter the constitution. In bicameral legislatures, there may be a process laid out for second or third readings of bills before a new law can enter into force. Alternatively, there may further be requirements for maximum terms that a government can keep power before holding an election.
Constitutional law is a major focus of legal studies and research. For example, most law students in the United States are required to take a class in Constitutional Law during their first year, and several law journals are devoted to the discussion of constitutional issues.
The doctrine of the rule of law dictates that government must be conducted according to law. This was first established by British legal theorist A. V. Dicey.
Dicey identified three essential elements of the British Constitution which were indicative of the rule of law:
Dicey's rule of law formula consists of three classic tenets. The first is that the regular law is supreme over arbitrary and discretionary powers. "[N]o man is punishable ... except for a distinct breach of the law established in the ordinary legal manner before the ordinary courts of the land."
The second is that all men are to stand equal in the eyes of the law. "...no man is above the law...every man, whatever be his rank or condition, is subject to the ordinary law of the realm and amenable to the jurisdiction of the ordinary tribunals"
The third is that the general ideas and principles that the constitution supports arise directly from the judgements and precedents issued by the judiciary. "We may say that the constitution is pervaded by the rule of law on the ground that the general principles of the constitution... are with us the result of judicial decisions determining the rights of private persons in particular cases brought before the courts"
Separation of powers is often regarded as a second limb functioning alongside the rule of law to curb the powers of the government. In many modern nation states, power is divided and vested into three branches of government: The legislature, the executive, and the judiciary are known as the horizontal separation of powers. The first and the second are harmonised in traditional Westminster system. Vertical separation of powers is decentralisation.
Election law is a subfield of constitutional law. It includes the rules governing the process of elections. These rules enable the translation of the will of the people into functioning democracies. Election law addresses issues who is entitled to vote, voter registration, ballot access, campaign finance and party funding, redistricting, apportionment, electronic voting and voting machines, accessibility of elections, election systems and formulas, vote counting, election disputes, referendums, and issues such as electoral fraud and electoral silence. | [

5,920 | Celtic languages | The Celtic languages (/ˈkɛltɪk/ KEL-tik) are a group of related languages descended from Proto-Celtic. They form a branch of the Indo-European language family. The term "Celtic" was first used to describe this language group by Edward Lhuyd in 1707, following Paul-Yves Pezron, who made the explicit link between the Celts described by classical writers and the Welsh and Breton languages.
During the first millennium BC, Celtic languages were spoken across much of Europe and central Anatolia. Today, they are restricted to the northwestern fringe of Europe and a few diaspora communities. There are six living languages: the four continuously living languages Breton, Irish, Scottish Gaelic and Welsh, and the two revived languages Cornish and Manx. All are minority languages in their respective countries, though there are continuing efforts at revitalisation. Welsh is an official language in Wales and Irish is an official language of Ireland and of the European Union. Welsh is the only Celtic language not classified as endangered by UNESCO. The Cornish and Manx languages became extinct in modern times. They have been the object of revivals and now each has several hundred second-language speakers.
Irish, Manx and Scottish Gaelic form the Goidelic languages, while Welsh, Cornish and Breton are Brittonic. All of these are Insular Celtic languages, since Breton, the only living Celtic language spoken in continental Europe, is descended from the language of settlers from Britain. There are a number of extinct but attested continental Celtic languages, such as Celtiberian, Galatian and Gaulish. Beyond that there is no agreement on the subdivisions of the Celtic language family. They may be divided into P-Celtic and Q-Celtic.
The Celtic languages have a rich literary tradition. The earliest specimens of written Celtic are Lepontic inscriptions from the 6th century BC in the Alps. Early Continental inscriptions used Italic and Paleohispanic scripts. Between the 4th and 8th centuries, Irish and Pictish were occasionally written in an original script, Ogham, but Latin script came to be used for all Celtic languages. Welsh has had a continuous literary tradition from the 6th century AD.
SIL Ethnologue lists six living Celtic languages, of which four have retained a substantial number of native speakers. These are: the Goidelic languages (Irish and Scottish Gaelic, both descended from Middle Irish) and the Brittonic languages (Welsh and Breton, descended from Common Brittonic). The other two, Cornish (Brittonic) and Manx (Goidelic), died out in modern times with their presumed last native speakers in 1777 and 1974 respectively. Revitalisation movements in the 2000s led to the reemergence of native speakers for both languages following their adoption by adults and children. By the 21st century, there were roughly one million native speakers of Celtic languages, increasing to 1.4 million speakers by 2010.
Celtic is divided into various branches:
Scholarly handling of Celtic languages has been contentious owing to scarceness of primary source data. Some scholars (such as Cowgill 1975; McCone 1991, 1992; and Schrijver 1995) posit that the primary distinction is between Continental Celtic and Insular Celtic, arguing that the differences between the Goidelic and Brittonic languages arose after these split off from the Continental Celtic languages. Other scholars (such as Schmidt 1988) make the primary distinction between P-Celtic and Q-Celtic languages based on the replacement of initial Q by initial P in some words. Most of the Gallic and Brittonic languages are P-Celtic, while the Goidelic and Celtiberian languages are Q-Celtic. The P-Celtic languages (also called Gallo-Brittonic) are sometimes seen (for example by Koch 1992) as a central innovating area as opposed to the more conservative peripheral Q-Celtic languages. According to Ranko Matasovic in the introduction to his 2009 Etymological Dictionary of Proto-Celtic : "Celtiberian...is almost certainly an independent branch on the Celtic genealogical tree, one that became separated from the others very early."
The Breton language is Brittonic, not Gaulish, though there may be some input from the latter, having been introduced from Southwestern regions of Britain in the post-Roman era and having evolved into Breton.
In the P/Q classification schema, the first language to split off from Proto-Celtic was Gaelic. It has characteristics that some scholars see as archaic, but others see as also being in the Brittonic languages (see Schmidt). In the Insular/Continental classification schema, the split of the former into Gaelic and Brittonic is seen as being late.
The distinction of Celtic into these four sub-families most likely occurred about 900 BC according to Gray and Atkinson but, because of estimation uncertainty, it could be any time between 1200 and 800 BC. However, they only considered Gaelic and Brythonic. The controversial paper by Forster and Toth included Gaulish and put the break-up much earlier at 3200 BC ± 1500 years. They support the Insular Celtic hypothesis. The early Celts were commonly associated with the archaeological Urnfield culture, the Hallstatt culture, and the La Tène culture, though the earlier assumption of association between language and culture is now considered to be less strong.
There are legitimate scholarly arguments for both the Insular Celtic hypothesis and the P-/Q-Celtic hypothesis. Proponents of each schema dispute the accuracy and usefulness of the other's categories. However, since the 1970s the division into Insular and Continental Celtic has become the more widely held view (Cowgill 1975; McCone 1991, 1992; Schrijver 1995), but in the middle of the 1980s, the P-/Q-Celtic theory found new supporters (Lambert 1994), because of the inscription on the Larzac piece of lead (1983), the analysis of which reveals another common phonetical innovation -nm- > -nu (Gaelic ainm / Gaulish anuana, Old Welsh enuein "names"), that is less accidental than only one. The discovery of a third common innovation would allow the specialists to come to the conclusion of a Gallo-Brittonic dialect (Schmidt 1986; Fleuriot 1986).
The interpretation of this and further evidence is still quite contested, and the main argument for Insular Celtic is connected with the development of verbal morphology and the syntax in Irish and British Celtic, which Schumacher regards as convincing, while he considers the P-Celtic/Q-Celtic division unimportant and treats Gallo-Brittonic as an outdated theory. Stifter affirms that the Gallo-Brittonic view is "out of favour" in the scholarly community as of 2008 and the Insular Celtic hypothesis "widely accepted".
When referring only to the modern Celtic languages, since no Continental Celtic language has living descendants, "Q-Celtic" is equivalent to "Goidelic" and "P-Celtic" is equivalent to "Brittonic".
How the family tree of the Celtic languages is ordered depends on which hypothesis is used:
Eska evaluates the evidence as supporting the following tree, based on shared innovations, though it is not always clear that the innovations are not areal features. It seems likely that Celtiberian split off before Cisalpine Celtic, but the evidence for this is not robust. On the other hand, the unity of Gaulish, Goidelic, and Brittonic is reasonably secure. Schumacher (2004, p. 86) had already cautiously considered this grouping to be likely genetic, based, among others, on the shared reformation of the sentence-initial, fully inflecting relative pronoun *i̯os, *i̯ā, *i̯od into an uninflected enclitic particle. Eska sees Cisalpine Gaulish as more akin to Lepontic than to Transalpine Gaulish.
Eska considers a division of Transalpine–Goidelic–Brittonic into Transalpine and Insular Celtic to be most probable because of the greater number of innovations in Insular Celtic than in P-Celtic, and because the Insular Celtic languages were probably not in great enough contact for those innovations to spread as part of a sprachbund. However, if they have another explanation (such as an SOV substratum language), then it is possible that P-Celtic is a valid clade, and the top branching would be:
Within the Indo-European family, the Celtic languages have sometimes been placed with the Italic languages in a common Italo-Celtic subfamily. This hypothesis fell somewhat out of favour after reexamination by American linguist Calvert Watkins in 1966. Irrespectively, some scholars such as Ringe, Warnow and Taylor have argued in favour of an Italo-Celtic grouping in 21st century theses.
Although there are many differences between the individual Celtic languages, they do show many family resemblances.
Examples:
The lexical similarity between the different Celtic languages is apparent in their core vocabulary, especially in terms of actual pronunciation. Moreover, the phonetic differences between languages are often the product of regular sound change (i.e. lenition of /b/ into /v/ or Ø).
The table below has words in the modern languages that were inherited direct from Proto-Celtic, as well as a few old borrowings from Latin that made their way into all the daughter languages. There is often a closer match between Welsh, Breton and Cornish on the one hand and Irish, Scottish Gaelic and Manx on the other. For a fuller list of comparisons, see the Swadesh list for Celtic.

5,921 | Color | Color (American English) or colour (Commonwealth English) is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra and interference. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelength, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain.
Colors have perceived properties such as hue, colorfulness (saturation) and luminance. Colors can also be additively mixed (commonly used for actual light) or subtractively mixed (commonly used for materials). If the colors are mixed in the right proportions, because of metamerism, they may look the same as a single-wavelength light. For convenience, colors can be organized in a color space, which when being abstracted as a mathematical color model can assign each region of color with a corresponding set of numbers. As such, color spaces are an essential tool for color reproduction in print, photography, computer monitors and television. The most well-known color models are RGB, CMYK, YUV, HSL and HSV.
Because the perception of color is an important aspect of human life, different colors have been associated with emotions, activity, and nationality. Names of color regions in different cultures can have different, sometimes overlapping areas. In visual arts, color theory is used to govern the use of colors in an aesthetically pleasing and harmonious way. The theory of color includes the color complements; color balance; and classification of primary colors (traditionally red, yellow, blue), secondary colors (traditionally orange, green, purple) and tertiary colors. The study of colors in general is called color science or colorology.
Electromagnetic radiation is characterized by its wavelength (or frequency) and its intensity. When the wavelength is within the visible spectrum (the range of wavelengths humans can perceive, approximately from 390 nm to 700 nm), it is known as "visible light".
Most light sources emit light at many different wavelengths; a source's spectrum is a distribution giving its intensity at each wavelength. Although the spectrum of light arriving at the eye from a given direction determines the color sensation in that direction, there are many more possible spectral combinations than color sensations. In fact, one may formally define a color as a class of spectra that give rise to the same color sensation, although such classes would vary widely among different species, and to a lesser extent among individuals within the same species. In each such class, the members are called metamers of the color in question. This effect can be visualized by comparing the light sources' spectral power distributions and the resulting colors.
The familiar colors of the rainbow in the spectrum—named using the Latin word for appearance or apparition by Isaac Newton in 1671—include all those colors that can be produced by visible light of a single wavelength only, the pure spectral or monochromatic colors. The table at right shows approximate frequencies (in terahertz) and wavelengths (in nanometers) for spectral colors in the visible range. Spectral colors have 100% purity, and are fully saturated. A complex mixture of spectral colors can be used to describe any color, which is the definition of a light power spectrum.
The color table should not be interpreted as a definitive list; the spectral colors form a continuous spectrum, and how it is divided into distinct colors linguistically is a matter of culture and historical contingency. Despite the ubiquitous ROYGBIV mnemonic used to remember the spectral colors in English, the inclusion or exclusion of colors in this table is contentious, with disagreement often focused on indigo and cyan. Even if the subset of color terms is agreed, their wavelength ranges and borders between them may not be.
The intensity of a spectral color, relative to the context in which it is viewed, may alter its perception considerably according to the Bezold–Brücke shift; for example, a low-intensity orange-yellow is brown, and a low-intensity yellow-green is olive green. In color models capable of representing spectral colors, such as CIELUV, a spectral color has the maximal saturation. In Helmholtz coordinates, this is described as 100% purity.
The physical color of an object depends on how it absorbs and scatters light. Most objects scatter light to some degree and do not reflect or transmit light specularly like glasses or mirrors. A transparent object allows almost all light to transmit or pass through, thus transparent objects are perceived as colorless. Conversely, an opaque object does not allow light to transmit through and instead absorbing or reflecting the light it receives. Like transparent objects, translucent objects allow light to transmit through, but translucent objects are seen colored because they scatter or absorb certain wavelengths of light via internal scatterance. The absorbed light is often dissipated as heat.
Although Aristotle and other ancient scientists had already written on the nature of light and color vision, it was not until Newton that light was identified as the source of the color sensation. In 1810, Goethe published his comprehensive Theory of Colors in which he provided a rational description of color experience, which 'tells us how it originates, not what it is'. (Schopenhauer)
In 1801 Thomas Young proposed his trichromatic theory, based on the observation that any color could be matched with a combination of three lights. This theory was later refined by James Clerk Maxwell and Hermann von Helmholtz. As Helmholtz puts it, "the principles of Newton's law of mixture were experimentally confirmed by Maxwell in 1856. Young's theory of color sensations, like so much else that this marvelous investigator achieved in advance of his time, remained unnoticed until Maxwell directed attention to it."
At the same time as Helmholtz, Ewald Hering developed the opponent process theory of color, noting that color blindness and afterimages typically come in opponent pairs (red-green, blue-orange, yellow-violet, and black-white). Ultimately these two theories were synthesized in 1957 by Hurvich and Jameson, who showed that retinal processing corresponds to the trichromatic theory, while processing at the level of the lateral geniculate nucleus corresponds to the opponent theory.
In 1931, an international group of experts known as the Commission internationale de l'éclairage (CIE) developed a mathematical color model, which mapped out the space of observable colors and assigned a set of three numbers to each.
The ability of the human eye to distinguish colors is based upon the varying sensitivity of different cells in the retina to light of different wavelengths. Humans are trichromatic—the retina contains three types of color receptor cells, or cones. One type, relatively distinct from the other two, is most responsive to light that is perceived as blue or blue-violet, with wavelengths around 450 nm; cones of this type are sometimes called short-wavelength cones or S cones (or misleadingly, blue cones). The other two types are closely related genetically and chemically: middle-wavelength cones, M cones, or green cones are most sensitive to light perceived as green, with wavelengths around 540 nm, while the long-wavelength cones, L cones, or red cones, are most sensitive to light that is perceived as greenish yellow, with wavelengths around 570 nm.
Light, no matter how complex its composition of wavelengths, is reduced to three color components by the eye. Each cone type adheres to the principle of univariance, which is that each cone's output is determined by the amount of light that falls on it over all wavelengths. For each location in the visual field, the three types of cones yield three signals based on the extent to which each is stimulated. These amounts of stimulation are sometimes called tristimulus values.
The response curve as a function of wavelength varies for each type of cone. Because the curves overlap, some tristimulus values do not occur for any incoming light combination. For example, it is not possible to stimulate only the mid-wavelength (so-called "green") cones; the other cones will inevitably be stimulated to some degree at the same time. The set of all possible tristimulus values determines the human color space. It has been estimated that humans can distinguish roughly 10 million different colors.
The other type of light-sensitive cell in the eye, the rod, has a different response curve. In normal situations, when light is bright enough to strongly stimulate the cones, rods play virtually no role in vision at all. On the other hand, in dim light, the cones are understimulated leaving only the signal from the rods, resulting in a colorless response. (Furthermore, the rods are barely sensitive to light in the "red" range.) In certain conditions of intermediate illumination, the rod response and a weak cone response can together result in color discriminations not accounted for by cone responses alone. These effects, combined, are summarized also in the Kruithof curve, which describes the change of color perception and pleasingness of light as a function of temperature and intensity.
While the mechanisms of color vision at the level of the retina are well-described in terms of tristimulus values, color processing after that point is organized differently. A dominant theory of color vision proposes that color information is transmitted out of the eye by three opponent processes, or opponent channels, each constructed from the raw output of the cones: a red–green channel, a blue–yellow channel, and a black–white "luminance" channel. This theory has been supported by neurobiology, and accounts for the structure of our subjective color experience. Specifically, it explains why humans cannot perceive a "reddish green" or "yellowish blue", and it predicts the color wheel: it is the collection of colors for which at least one of the two color channels measures a value at one of its extremes.
The exact nature of color perception beyond the processing already described, and indeed the status of color as a feature of the perceived world or rather as a feature of our perception of the world—a type of qualia—is a matter of complex and continuing philosophical dispute.
From the V1 blobs, color information is sent to cells in the second visual area, V2. The cells in V2 that are most strongly color tuned are clustered in the "thin stripes" that, like the blobs in V1, stain for the enzyme cytochrome oxidase (separating the thin stripes are interstripes and thick stripes, which seem to be concerned with other visual information like motion and high-resolution form). Neurons in V2 then synapse onto cells in the extended V4. This area includes not only V4, but two other areas in the posterior inferior temporal cortex, anterior to area V3, the dorsal posterior inferior temporal cortex, and posterior TEO. Area V4 was initially suggested by Semir Zeki to be exclusively dedicated to color, and he later showed that V4 can be subdivided into subregions with very high concentrations of color cells separated from each other by zones with lower concentration of such cells though even the latter cells respond better to some wavelengths than to others, a finding confirmed by subsequent studies. The presence in V4 of orientation-selective cells led to the view that V4 is involved in processing both color and form associated with color but it is worth noting that the orientation selective cells within V4 are more broadly tuned than their counterparts in V1, V2 and V3. Color processing in the extended V4 occurs in millimeter-sized color modules called globs. This is the part of the brain in which color is first processed into the full range of hues found in color space.
A color vision deficiency causes an individual to perceive a smaller gamut of colors than the standard observer with normal color vision. The effect can be mild, having lower "color resolution" (i.e. anomalous trichromacy), moderate, lacking an entire dimension or channel of color (e.g. dichromacy), or complete, lacking all color perception (i.e. monochromacy). Most forms of color blindness derive from one or more of the three classes of cone cells either being missing, having a shifted spectral sensitivity or having lower responsiveness to incoming light. In addition, cerebral achromatopsia is caused by neural anomalies in those parts of the brain where visual processing takes place.
Some colors that appear distinct to an individual with normal color vision will appear metameric to the color blind. The most common form of color blindness is congenital red–green color blindness, affecting ~8% of males. Individuals with the strongest form of this condition (dichromacy) will experience blue and purple, green and yellow, teal and gray as colors of confusion, i.e. metamers.
Outside of humans, which are mostly trichromatic (having three types of cones), most mammals are dichromatic, possessing only two cones. However, outside of mammals, most vertebrate are tetrachromatic, having four types of cones, and includes most, birds, reptiles, amphibians and bony fish. An extra dimension of color vision means these vertebrates can see two distinct colors that a normal human would view as metamers. Some invertebrates, such as the mantis shrimp, have an even higher number of cones (12) that could lead to a richer color gamut than even imaginable by humans.
The existence of human tetrachromats is a contentious notion. As many as half of all human females have 4 distinct cone classes, which could enable tetrachromacy. However, a distinction must be made between retinal (or weak) tetrachromats, which express four cone classes in the retina, and functional (or strong) tetrachromats, which are able to make the enhanced color discriminations expected of tetrachromats. In fact, there is only one peer-reviewed report of a functional tetrachromat. It is estimated that while the average person is able to see one million colors, someone with functional tetrachromacy could see a hundred million colors.
In certain forms of synesthesia, perceiving letters and numbers (grapheme–color synesthesia) or hearing sounds (chromesthesia) will evoke a perception of color. Behavioral and functional neuroimaging experiments have demonstrated that these color experiences lead to changes in behavioral tasks and lead to increased activation of brain regions involved in color perception, thus demonstrating their reality, and similarity to real color percepts, albeit evoked through a non-standard route. Synesthesia can occur genetically, with 4% of the population having variants associated with the condition. Synesthesia has also been known to occur with brain damage, drugs, and sensory deprivation.
The philosopher Pythagoras experienced synesthesia and provided one of the first written accounts of the condition in approximately 550 BCE. He created mathematical equations for musical notes that could form part of a scale, such as an octave.
After exposure to strong light in their sensitivity range, photoreceptors of a given type become desensitized. For a few seconds after the light ceases, they will continue to signal less strongly than they otherwise would. Colors observed during that period will appear to lack the color component detected by the desensitized photoreceptors. This effect is responsible for the phenomenon of afterimages, in which the eye may continue to see a bright figure after looking away from it, but in a complementary color. Afterimage effects have also been used by artists, including Vincent van Gogh.
When an artist uses a limited color palette, the human eye tends to compensate by seeing any gray or neutral color as the color which is missing from the color wheel. For example, in a limited palette consisting of red, yellow, black, and white, a mixture of yellow and black will appear as a variety of green, a mixture of red and black will appear as a variety of purple, and pure gray will appear bluish.
The trichromatic theory is strictly true when the visual system is in a fixed state of adaptation. In reality, the visual system is constantly adapting to changes in the environment and compares the various colors in a scene to reduce the effects of the illumination. If a scene is illuminated with one light, and then with another, as long as the difference between the light sources stays within a reasonable range, the colors in the scene appear relatively constant to us. This was studied by Edwin H. Land in the 1970s and led to his retinex theory of color constancy.
Both phenomena are readily explained and mathematically modeled with modern theories of chromatic adaptation and color appearance (e.g. CIECAM02, iCAM). There is no need to dismiss the trichromatic theory of vision, but rather it can be enhanced with an understanding of how the visual system adapts to changes in the viewing environment.
Color reproduction is the science of creating colors for the human eye that faithfully represent the desired color. It focuses on how to construct a spectrum of wavelengths that will best evoke a certain color in an observer. Most colors are not spectral colors, meaning they are mixtures of various wavelengths of light. However, these non-spectral colors are often described by their dominant wavelength, which identifies the single wavelength of light that produces a sensation most similar to the non-spectral color. Dominant wavelength is roughly akin to hue.
There are many color perceptions that by definition cannot be pure spectral colors due to desaturation or because they are purples (mixtures of red and violet light, from opposite ends of the spectrum). Some examples of necessarily non-spectral colors are the achromatic colors (black, gray, and white) and colors such as pink, tan, and magenta.
Two different light spectra that have the same effect on the three color receptors in the human eye will be perceived as the same color. They are metamers of that color. This is exemplified by the white light emitted by fluorescent lamps, which typically has a spectrum of a few narrow bands, while daylight has a continuous spectrum. The human eye cannot tell the difference between such light spectra just by looking into the light source, although the color rendering index of each light source may affect the color of objects illuminated by these metameric light sources.
Similarly, most human color perceptions can be generated by a mixture of three colors called primaries. This is used to reproduce color scenes in photography, printing, television, and other media. There are a number of methods or color spaces for specifying a color in terms of three particular primary colors. Each method has its advantages and disadvantages depending on the particular application.
No mixture of colors, however, can produce a response truly identical to that of a spectral color, although one can get close, especially for the longer wavelengths, where the CIE 1931 color space chromaticity diagram has a nearly straight edge. For example, mixing green light (530 nm) and blue light (460 nm) produces cyan light that is slightly desaturated, because response of the red color receptor would be greater to the green and blue light in the mixture than it would be to a pure cyan light at 485 nm that has the same intensity as the mixture of blue and green.
Because of this, and because the primaries in color printing systems generally are not pure themselves, the colors reproduced are never perfectly saturated spectral colors, and so spectral colors cannot be matched exactly. However, natural scenes rarely contain fully saturated colors, thus such scenes can usually be approximated well by these systems. The range of colors that can be reproduced with a given color reproduction system is called the gamut. The CIE chromaticity diagram can be used to describe the gamut.
Another problem with color reproduction systems is connected with the initial measurement of color, or colorimetry. The characteristics of the color sensors in measurement devices (e.g. cameras, scanners) are often very far from the characteristics of the receptors in the human eye.
A color reproduction system "tuned" to a human with normal color vision may give very inaccurate results for other observers, according to color vision deviations to the standard observer.
The different color response of different devices can be problematic if not properly managed. For color information stored and transferred in digital form, color management techniques, such as those based on ICC profiles, can help to avoid distortions of the reproduced colors. Color management does not circumvent the gamut limitations of particular output devices, but can assist in finding good mapping of input colors into the gamut that can be reproduced.
Additive color is light created by mixing together light of two or more different colors. Red, green, and blue are the additive primary colors normally used in additive color systems such as projectors, televisions, and computer terminals.
Subtractive coloring uses dyes, inks, pigments, or filters to absorb some wavelengths of light and not others. The color that a surface displays comes from the parts of the visible spectrum that are not absorbed and therefore remain visible. Without pigments or dye, fabric fibers, paint base and paper are usually made of particles that scatter white light (all colors) well in all directions. When a pigment or ink is added, wavelengths are absorbed or "subtracted" from white light, so light of another color reaches the eye.
If the light is not a pure white source (the case of nearly all forms of artificial lighting), the resulting spectrum will appear a slightly different color. Red paint, viewed under blue light, may appear black. Red paint is red because it scatters only the red components of the spectrum. If red paint is illuminated by blue light, it will be absorbed by the red paint, creating the appearance of a black object.
The subtractive model also predicts the color resulting from a mixture of paints, or similar medium such as fabric dye, whether applied in layers or mixed together prior to application. In the case of paint mixed before application, incident light interacts with many different pigment particles at various depths inside the paint layer before emerging.
Structural colors are colors caused by interference effects rather than by pigments. Color effects are produced when a material is scored with fine parallel lines, formed of one or more parallel thin layers, or otherwise composed of microstructures on the scale of the color's wavelength. If the microstructures are spaced randomly, light of shorter wavelengths will be scattered preferentially to produce Tyndall effect colors: the blue of the sky (Rayleigh scattering, caused by structures much smaller than the wavelength of light, in this case, air molecules), the luster of opals, and the blue of human irises. If the microstructures are aligned in arrays, for example, the array of pits in a CD, they behave as a diffraction grating: the grating reflects different wavelengths in different directions due to interference phenomena, separating mixed "white" light into light of different wavelengths. If the structure is one or more thin layers then it will reflect some wavelengths and transmit others, depending on the layers' thickness.
Structural color is studied in the field of thin-film optics. The most ordered or the most changeable structural colors are iridescent. Structural color is responsible for the blues and greens of the feathers of many birds (the blue jay, for example), as well as certain butterfly wings and beetle shells. Variations in the pattern's spacing often give rise to an iridescent effect, as seen in peacock feathers, soap bubbles, films of oil, and mother of pearl, because the reflected color depends upon the viewing angle. Numerous scientists have carried out research in butterfly wings and beetle shells, including Isaac Newton and Robert Hooke. Since 1942, electron micrography has been used, advancing the development of products that exploit structural color, such as "photonic" cosmetics.
Colors, their meanings and associations can play a major role in works of art, including literature.
Individual colors have a variety of cultural associations such as national colors (in general described in individual color articles and color symbolism). The field of color psychology attempts to identify the effects of color on human emotion and activity. Chromotherapy is a form of alternative medicine attributed to various Eastern traditions. Colors have different associations in different countries and cultures.
Different colors have been demonstrated to have effects on cognition. For example, researchers at the University of Linz in Austria demonstrated that the color red significantly decreases cognitive functioning in men. The combination of the colors red and yellow together can induce hunger, which has been capitalized on by a number of chain restaurants.
Color plays a role in memory development too. A photograph that is in black and white is slightly less memorable than one in color. Studies also show that wearing bright colors makes you more memorable to people you meet.
Colors vary in several different ways, including hue (shades of red, orange, yellow, green, blue, and violet, etc), saturation, brightness. Some color words are derived from the name of an object of that color, such as "orange" or "salmon", while others are abstract, like "red".
In the 1969 study Basic Color Terms: Their Universality and Evolution, Brent Berlin and Paul Kay describe a pattern in naming "basic" colors (like "red" but not "red-orange" or "dark red" or "blood red", which are "shades" of red). All languages that have two "basic" color names distinguish dark/cool colors from bright/warm colors. The next colors to be distinguished are usually red and then yellow or green. All languages with six "basic" colors include black, white, red, green, blue, and yellow. The pattern holds up to a set of twelve: black, gray, white, pink, red, orange, yellow, green, blue, purple, brown, and azure (distinct from blue in Russian and Italian, but not English). | [

Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra and interference.

Other animals may have a different number of cone cell types or have eyes sensitive to different wavelength, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain.",

If the microstructures are aligned in arrays, for example, the array of pits in a CD, they behave as a diffraction grating: the grating reflects different wavelengths in different directions due to interference phenomena, separating mixed \"white\" light into light of different wavelengths. If the structure is one or more thin layers then it will reflect some wavelengths and transmit others, depending on the layers' thickness.",

] | Color or colour is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra and interference. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelength, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain. Colors have perceived properties such as hue, colorfulness (saturation) and luminance. Colors can also be additively mixed or subtractively mixed. If the colors are mixed in the right proportions, because of metamerism, they may look the same as a single-wavelength light. For convenience, colors can be organized in a color space, which when being abstracted as a mathematical color model can assign each region of color with a corresponding set of numbers. As such, color spaces are an essential tool for color reproduction in print, photography, computer monitors and television. The most well-known color models are RGB, CMYK, YUV, HSL and HSV. Because the perception of color is an important aspect of human life, different colors have been associated with emotions, activity, and nationality. Names of color regions in different cultures can have different, sometimes overlapping areas. In visual arts, color theory is used to govern the use of colors in an aesthetically pleasing and harmonious way. The theory of color includes the color complements; color balance; and classification of primary colors, secondary colors and tertiary colors. The study of colors in general is called color science or colorology. | 2001-11-01T04:27:18Z | 2023-12-23T21:04:40Z | [

5,926 | Computation | A computation is any type of arithmetic or non-arithmetic calculation that is well-defined. Common examples of computations are mathematical equations and computer algorithms.
Mechanical or electronic devices (or, historically, people) that perform computations are known as computers. The study of computation is the field of computability, itself a sub-field of computer science.
The notion that mathematical statements should be 'well-defined' had been argued by mathematicians since at least the 1600s, but agreement on a suitable definition proved elusive. A candidate definition was proposed independently by several mathematicians in the 1930s. The best-known variant was formalised by the mathematician Alan Turing, who defined a well-defined statement or calculation as any statement that could be expressed in terms of the initialisation parameters of a Turing Machine. Other (mathematically equivalent) definitions include Alonzo Church's lambda-definability, Herbrand-Gödel-Kleene's general recursiveness and Emil Post's 1-definability.
Today, any formal statement or calculation that exhibits this quality of well-definedness is termed computable, while the statement or calculation itself is referred to as a computation.
Turing's definition apportioned "well-definedness" to a very large class of mathematical statements, including all well-formed algebraic statements, and all statements written in modern computer programming languages.
Despite the widespread uptake of this definition, there are some mathematical concepts that have no well-defined characterisation under this definition. This includes the halting problem and the busy beaver game. It remains an open question as to whether there exists a more powerful definition of 'well-defined' that is able to capture both computable and 'non-computable' statements.
Some examples of mathematical statements that are computable include:
Some examples of mathematical statements that are not computable include:
Computation can be seen as a purely physical process occurring inside a closed physical system called a computer. Turing's 1937 proof, On Computable Numbers, with an Application to the Entscheidungsproblem, demonstrated that there is a formal equivalence between computable statements and particular physical systems, commonly called computers. Examples of such physical systems are: Turing machines, human mathematicians following strict rules, digital computers, mechanical computers, analog computers and others.
An alternative account of computation is found throughout the works of Hilary Putnam and others. Peter Godfrey-Smith has dubbed this the "simple mapping account." Gualtiero Piccinini's summary of this account states that a physical system can be said to perform a specific computation when there is a mapping between the state of that system and the computation such that the "microphysical states [of the system] mirror the state transitions between the computational states."
Philosophers such as Jerry Fodor have suggested various accounts of computation with the restriction that semantic content be a necessary condition for computation (that is, what differentiates an arbitrary physical system from a computing system is that the operands of the computation represent something). This notion attempts to prevent the logical abstraction of the mapping account of pancomputationalism, the idea that everything can be said to be computing everything.
Gualtiero Piccinini proposes an account of computation based on mechanical philosophy. It states that physical computing systems are types of mechanisms that, by design, perform physical computation, or the manipulation (by a functional mechanism) of a "medium-independent" vehicle according to a rule. "Medium-independence" requires that the property can be instantiated by multiple realizers and multiple mechanisms, and that the inputs and outputs of the mechanism also be multiply realizable. In short, medium-independence allows for the use of physical variables with properties other than voltage (as in typical digital computers); this is imperative in considering other types of computation, such as that which occurs in the brain or in a quantum computer. A rule, in this sense, provides a mapping among inputs, outputs, and internal states of the physical computing system.
In the theory of computation, a diversity of mathematical models of computation has been developed. Typical mathematical models of computers are the following:
Giunti calls the models studied by computation theory computational systems, and he argues that all of them are mathematical dynamical systems with discrete time and discrete state space. He maintains that a computational system is a complex object which consists of three parts. First, a mathematical dynamical system D S {\displaystyle DS} with discrete time and discrete state space; second, a computational setup H = ( F , B F ) {\displaystyle H=\left(F,B_{F}\right)} , which is made up of a theoretical part F {\displaystyle F} , and a real part B F {\displaystyle B_{F}} ; third, an interpretation I D S , H {\displaystyle I_{DS,H}} , which links the dynamical system D S {\displaystyle DS} with the setup H {\displaystyle H} . | [

5,928 | Clown | A clown is a person who performs comedy and arts in a state of open-mindedness using physical comedy, typically while wearing distinct makeup or costuming and reversing folkway-norms. Clowns have a varied tradition with significant variations in costume and performance. The most recognisable clowns are those that commonly perform in the circus, characterized by colorful wigs, red noses, and oversized shoes. However, clowns have also played roles in theater and folklore, like the court jesters of the Middle Ages and the jesters and ritual clowns of various indigenous cultures. Their performances can elicit a range of emotions, from humor and laughter to fear and discomfort, reflecting complex societal and psychological dimensions. Through the centuries, clowns have continued to play significant roles in society, evolving alongside changing cultural norms and artistic expressions.
The most ancient clowns have been found in the Fifth Dynasty of Egypt, around 2400 BC. Unlike court jesters, clowns have traditionally served a socio-religious and psychological role, and traditionally the roles of priest and clown have been held by the same persons. Peter Berger writes, "It seems plausible that folly and fools, like religion and magic, meet some deeply rooted needs in human society." For this reason, clowning is often considered an important part of training as a physical performance discipline, partly because tricky subject matter can be dealt with, but also because it requires a high level of risk and play in the performer.
In anthropology, the term clown has been extended to comparable jester or fool characters in non-Western cultures. A society in which such clowns have an important position are termed clown societies, and a clown character involved in a religious or ritual capacity is known as a ritual clown.
A Heyoka is an individual in Lakota and Dakota culture cultures who lives outside the constraints of normal cultural roles, playing the role of a backwards clown by doing everything in reverse. The Heyoka role is sometimes best filled by a Winkte.
Many native tribes have a history of clowning. The Canadian clowning method developed by Richard Pochinko and furthered by his former apprentice, Sue Morrison, combines European and Native American clowning techniques. In this tradition, masks are made of clay while the creator's eyes are closed. A mask is made for each direction of the medicine wheel. During this process, the clown creates a personal mythology that explores their personal experiences.
"Grimaldi was the first recognizable ancestor of the modern clown, sort of the Homo erectus of clown evolution. Before him, a clown may have worn make-up, but it was usually just a bit of rouge on the cheeks to heighten the sense of them being florid, funny drunks or rustic yokels. Grimaldi, however, suited up in bizarre, colorful costumes, stark white face paint punctuated by spots of bright red on his cheeks and topped with a blue mohawk. He was a master of physical comedy—he leapt in the air, stood on his head, fought himself in hilarious fisticuffs that had audiences rolling in the aisles—as well as of satire lampooning the absurd fashions of the day, comic impressions, and ribald songs."
—The History and Psychology of Clowns Being Scary, Smithsonian.
The circus clown tradition developed out of earlier comedic roles in theatre or Varieté shows during the 19th to mid 20th centuries. This recognizable character features outlandish costumes, distinctive makeup, colorful wigs, exaggerated footwear, and colorful clothing, with the style generally being designed to entertain large audiences.
The first mainstream clown role was portrayed by Joseph Grimaldi (who also created the traditional whiteface make-up design). In the early 1800s, he expanded the role of Clown in the harlequinade that formed part of British pantomimes, notably at the Theatre Royal, Drury Lane and the Sadler's Wells and Covent Garden theatres. He became so dominant on the London comic stage that harlequinade Clowns became known as "Joey", and both the nickname and Grimaldi's whiteface make-up design are still used by other clowns.
The comedy that clowns perform is usually in the role of a fool whose everyday actions and tasks become extraordinary—and for whom the ridiculous, for a short while, becomes ordinary. This style of comedy has a long history in many countries and cultures across the world. Some writers have argued that due to the widespread use of such comedy and its long history it is a need that is part of the human condition.
The modern clowning school of comedy in the 21st century diverged from white-face clown tradition, with more of an emphasis on personal vulnerability and heightened sexuality.
The clown character developed out of the zanni rustic fool characters of the early modern commedia dell'arte, which were themselves directly based on the rustic fool characters of ancient Greek and Roman theatre. Rustic buffoon characters in Classical Greek theater were known as sklêro-paiktês (from paizein: to play (like a child)) or deikeliktas, besides other generic terms for rustic or peasant. In Roman theater, a term for clown was fossor, literally digger; labourer.
The English word clown was first recorded c. 1560 (as clowne, cloyne) in the generic meaning rustic, boor, peasant. The origin of the word is uncertain, perhaps from a Scandinavian word cognate with clumsy. It is in this sense that Clown is used as the name of fool characters in Shakespeare's Othello and The Winter's Tale. The sense of clown as referring to a professional or habitual fool or jester developed soon after 1600, based on Elizabethan rustic fool characters such as Shakespeare's.
The harlequinade developed in England in the 17th century, inspired by Arlecchino and the commedia dell'arte. It was here that Clown came into use as the given name of a stock character. Originally a foil for Harlequin's slyness and adroit nature, Clown was a buffoon or bumpkin fool who resembled less a jester than a comical idiot. He was a lower class character dressed in tattered servants' garb.
The now-classical features of the clown character were developed in the early 1800s by Joseph Grimaldi, who played Clown in Charles Dibdin's 1800 pantomime Peter Wilkins: or Harlequin in the Flying World at Sadler's Wells Theatre, where Grimaldi built the character up into the central figure of the harlequinade.
The circus clown developed in the 19th century. The modern circus derives from Philip Astley's London riding school, which opened in 1768. Astley added a clown to his shows to amuse the spectators between equestrian sequences. American comedian George L. Fox became known for his clown role, directly inspired by Grimaldi, in the 1860s. Tom Belling senior (1843–1900) developed the red clown or Auguste (Dummer August) character c. 1870, acting as a foil for the more sophisticated white clown. Belling worked for Circus Renz in Vienna. Belling's costume became the template for the modern stock character of circus or children's clown, based on a lower class or hobo character, with red nose, white makeup around the eyes and mouth, and oversized clothes and shoes. The clown character as developed by the late 19th century is reflected in Ruggero Leoncavallo's 1892 opera Pagliacci (Clowns). Belling's Auguste character was further popularized by Nicolai Poliakoff's Coco in the 1920s to 1930s.
The English word clown was borrowed, along with the circus clown act, by many other languages, such as French clown, Russian (and other Slavic languages) кло́ун, Greek κλόουν, Danish/Norwegian klovn, Romanian clovn etc.
Italian retains Pagliaccio, a Commedia dell'arte zanni character, and derivations of the Italian term are found in other Romance languages, such as French Paillasse, Spanish payaso, Catalan/Galician pallasso, Portuguese palhaço, Greek παλιάτσος, Turkish palyaço, German Pajass (via French) Yiddish פּאַיאַץ (payats), Russian пая́ц, Romanian paiață.
In the early 20th century, with the disappearance of the rustic simpleton or village idiot character of everyday experience, North American circuses developed characters such as the tramp or hobo. Examples include Marceline Orbes, who performed at the Hippodrome Theater (1905), Charlie Chaplin's The Tramp (1914), and Emmett Kelly's Weary Willie based on hobos of the Depression era. Another influential tramp character was played by Otto Griebling during the 1930s to 1950s. Red Skelton's Dodo the Clown in The Clown (1953), depicts the circus clown as a tragicomic stock character, "a funny man with a drinking problem".
In the United States, Bozo the Clown was an influential Auguste character since the late 1950s. The Bozo Show premiered in 1960 and appeared nationally on cable television in 1978. McDonald's derived its mascot clown, Ronald McDonald, from the Bozo character in the 1960s. Willard Scott, who had played Bozo during 1959–1962, performed as the mascot in 1963 television spots. The McDonald's trademark application for the character dates to 1967.
Based on the Bozo template, the US custom of birthday clown, private contractors who offer to perform as clowns at children's parties, developed in the 1960s to 1970s. The strong association of the (Bozo-derived) clown character with children's entertainment as it has developed since the 1960s also gave rise to Clown Care or hospital clowning in children's hospitals by the mid-1980s. Clowns of America International (established 1984) and World Clown Association (established 1987) are associations of semi-professionals and professional performers.
The shift of the Auguste or red clown character from his role as a foil for the white in circus or pantomime shows to a Bozo-derived standalone character in children's entertainment by the 1980s also gave rise to the evil clown character, with the attraction of clowns for small children being based in their fundamentally threatening or frightening nature. The fear of clowns, particularly circus clowns, has become known by the term "coulrophobia."
There are different types of clowns portrayed around the world. They include
The classical pairing of the White Clown with Auguste in modern tradition has a precedent in the pairing of Pierrot and Harlequin in the Commedia dell'arte. Originally, Harlequin's role was that of a light-hearted, nimble and astute servant, paired with the sterner and melancholic Pierrot.
In the 18th-century English Harlequinade, Harlequin was now paired with Clown. As developed by Joseph Grimaldi around 1800, Clown became the mischievous and brutish foil for the more sophisticated Harlequin, who became more of a romantic character. The most influential such pair in Victorian England were the Payne Brothers, active during the 1860s and 1870s.
The white clown, or clown blanc in French, is a sophisticated character, as opposed to the clumsy Auguste. The two types are also distinguished as the sad clown (blanc) and happy clown (Auguste).
The Auguste face base makeup color is a variation of pink, red, or tan rather than white. Features are exaggerated in size, and are typically red and black in color. The mouth is thickly outlined with white (called the muzzle) as are the eyes. Appropriate to the character, the Auguste can be dressed in either well-fitted garb or a costume that does not fit – oversize or too small, either is appropriate. Bold colors, large prints or patterns, and suspenders often characterize Auguste costumes.
The Auguste character-type is often an anarchist, a joker, or a fool. He is clever and has much lower status than the whiteface. Classically the whiteface character instructs the Auguste character to perform his bidding. The Auguste has a hard time performing a given task, which leads to funny situations. Sometimes the Auguste plays the role of an anarchist and purposefully has trouble following the whiteface's directions. Sometimes the Auguste is confused or is foolish and makes errors less deliberately.
The contra-auguste plays the role of the mediator between the white clown and the Auguste character. He has a lower status than the white clown but a higher status than the Auguste. He aspires to be more like the white clown and often mimics everything the white clown does to try to gain approval. If there is a contra-auguste character, he often is instructed by the whiteface to correct the Auguste when he is doing something wrong.
There are two major types of clowns with whiteface makeup: The classic white clown is derived from the Pierrot character. His makeup is white, usually with facial features such as eyebrows emphasized in black. He is the more intelligent and sophisticated clown, contrasting with the rude or grotesque Auguste types. Francesco Caroli and Glenn "Frosty" Little are examples of this type. The second type of whiteface is the buffoonish clown of the Bozo type, known as Comedy or Grotesque Whiteface. This type has grotesquely emphasized features, especially a red nose and red mouth, often with partial (mostly red) hair. In the comedic partnership of Abbott and Costello, Bud Abbot would have been the classic whiteface and Lou Costello the comedy whiteface or Auguste.
Traditionally, the whiteface clown uses clown white makeup to cover the entire face and neck, leaving none of the underlying natural skin visible. In the European whiteface makeup, the ears are painted red.
Whiteface makeup was originally designed by Joseph Grimaldi in 1801. He began by painting a white base over his face, neck and chest before adding red triangles on the cheeks, thick eyebrows and large red lips set in a mischievous grin. Grimaldi's design is used by many modern clowns. According to Grimaldi's biographer Andrew McConnell Stott, it was one of the most important theatrical designs of the 1800s.
America's first great whiteface clown was stage star George "G.L." Fox. Inspired by Grimaldi, Fox popularised the Humpty Dumpty stories throughout the U.S. in the 1860s.
The scary clown, also known as the evil clown or killer clown, is a subversion of the traditional comic clown character, in which the playful trope is instead depicted in a more disturbing nature through the use of horror elements and dark humor. The character can be seen as playing on the sense of unease felt by those with coulrophobia, the fear of clowns. The modern archetype of the evil clown was popularized by DC Comics character the Joker starting in 1940 and again by Pennywise in Stephen King's novel IT, which introduced the fear of an evil clown to a modern audience. In the novel, the eponymous character is a pan-dimensional monster which feeds mainly on children by luring them in the form of a clown, named "Pennywise", and then assuming the shape of whatever the victim fears the most.
The character clown adopts an eccentric character of some type, such as a butcher, a baker, a policeman, a housewife or hobo. Prime examples of this type of clown are the circus tramps Otto Griebling and Emmett Kelly. Red Skelton, Harold Lloyd, Buster Keaton, Charlie Chaplin, Rowan Atkinson and Sacha Baron Cohen would all fit the definition of a character clown.
The character clown makeup is a comic slant on the standard human face. Their makeup starts with a flesh tone base and may make use of anything from glasses, mustaches and beards to freckles, warts, big ears or strange haircuts.
The most prevalent character clown in the American circus is the hobo, tramp or bum clown. There are subtle differences in the American character clown types. The primary differences among these clown types is attitude. According to American circus expert Hovey Burgess, they are:
The World Clown Association is a worldwide organization for clowns, jugglers, magicians, and face painters. It holds an annual convention, mainly in the United States.
Clowns of America International is a Minnesota-based non-profit clown arts membership organization which aims "to share, educate, and act as a gathering place for serious minded amateurs, semiprofessionals, and professional clowns".
Clowns International is a British clowning organisation dating back to the 1940s. It is responsible for the Clown Egg Register.
In the circus, a clown might perform other circus roles or skills. Clowns may perform such skills as tightrope, juggling, unicycling, Master of Ceremonies, or ride an animal. Clowns may also "sit in" with the orchestra. Other circus performers may also temporarily stand in for a clown and perform their skills in clown costume.
Frameworks are the general outline of an act that clowns use to help them build out an act. Frameworks can be loose, including only a general beginning and ending to the act, leaving it up to the clown's creativity to fill in the rest, or at the other extreme a fully developed script that allows very little room for creativity.
Shows are the overall production that a clown is a part of, it may or may not include elements other than clowning, such as in a circus show. In a circus context, clown shows are typically made up of some combination of entrées, side dishes, clown stops, track gags, gags and bits.
Clown Stops or interludes are the brief appearances of clowns in a circus while the props and rigging are changed. These are typically made up of a few gags or several bits. Clown stops will always have a beginning, a middle, and an end to them, invariably culminating in a blow-off. These are also called reprises or run-ins by many, and in today's circus they are an art form in themselves. Originally they were bits of business usually parodying the preceding act. If for instance there had been a tightrope walker the reprise would involve two chairs with a piece of rope between and the clown trying to imitate the artiste by trying to walk between them, with the resulting falls and cascades bringing laughter from the audience. Today, interludes are far more complex, and in many modern shows the clowning is a thread that links the whole show together.
Among the more well-known clown stunts are: squirting flower; the too-many-clowns-coming-out-of-a-tiny-car stunt; doing just about anything with a rubber chicken, tripping over one's own feet (or an air pocket or imaginary blemish in the floor), or riding any number of ridiculous vehicles or clown bicycles. Individual prop stunts are generally considered individual bits. | [

5,930 | Coffea | Coffea is a genus of flowering plants in the family Rubiaceae. Coffea species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste.
The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. The coffee trade relies heavily on two of the over 120 species, Coffea arabica (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and Coffea canephora (known as "Robusta"), which accounts for about 20–40%. Both coffee species are vulnerable to shifting growing zones caused by climate change, likely to result in a decline in production in some of the most important growing regions.
There are over 120 species of Coffea, which is grown from seed. The two most popular are Coffea arabica (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and Coffea canephora (known as "Robusta"), which accounts for about 20–40%. C. arabica is preferred for its sweeter taste, while C. canephora has a higher caffeine content. C. arabica has its origins in the highlands of Ethiopia and the Boma Plateau of Sudan, and was the result of a hybrid between C. canephora and C. eugenioides.
The trees produce edible red or purple fruits, which are described either as epigynous berries or as indehiscent drupes. The fruit is often referred to as a "coffee cherry," and it contains two seeds, called "coffee beans." Despite these terms, coffee is neither a true cherry (the fruit of certain species in the genus Prunus) nor a true bean (seeds from plants in the family Fabaceae).
In about 5–10% of any crop of coffee fruits, only a single bean is found. Called a peaberry, it is smaller and rounder than a normal coffee bean.
When grown in the tropics, coffee is a vigorous bush or small tree that usually grows to a height of 3–3.5 m (9.8–11.5 ft). Most commonly cultivated coffee species grow best at high elevations, but do not tolerate freezing temperatures.
The tree of Coffea arabica will grow fruits after three to five years, producing for an average of 50 to 60 years, although up to 100 is possible. The white flowers are highly scented. The fruit takes about nine months to ripen.
The caffeine in coffee beans serves as a toxic substance protecting the seeds of the plant, a form of natural plant defense against herbivory. Caffeine simultaneously attracts pollinators, specifically honeybees, by creating an olfactory memory that signals bees to return to the plant's flowers. Not all Coffea species contain caffeine, and the earliest species had little or no caffeine content. Caffeine has evolved independently in multiple lineages of Coffea in Africa, perhaps in response to high pest predation in the humid environments of West-Central Africa. Caffeine has also evolved independently in the more distantly related genera Theobroma (cacao) and Camellia (tea). This suggests that caffeine production is an adaptive trait in coffee and plant evolution. The fruit and leaves also contain caffeine, and can be used to make coffee cherry tea and coffee-leaf tea. The fruit is also used in many brands of soft drink as well as pre-packaged teas.
Several insect pests affect coffee production, including the coffee borer beetle (Hypothenemus hampei) and the coffee leafminer (Leucoptera caffeina).
Coffee is used as a food plant by the larvae of some Lepidoptera (butterfly and moth) species, Dalcera abrasa, turnip moth and some members of the genus Endoclita, including E. damor and E. malabaricus.
New species of Coffea are still being identified in the 2000s. In 2008 and 2009, researchers from the Royal Botanic Gardens, Kew named seven from the mountains of northern Madagascar, including C. ambongensis, C. boinensis, C. labatii, C. pterocarpa, C. bissetiae, and C. namorokensis.
In 2008, two new species were discovered in Cameroon. Coffea charrieriana, which is caffeine-free, and Coffea anthonyi. By crossing the new species with other known coffees, two new features might be introduced to cultivated coffee plants: beans without caffeine and self-pollination.
In 2011, Coffea absorbed the twenty species of the former genus Psilanthus due to the morphological and genetic similarities between the two genera. Historically, the two have been considered distinct genera due to differences in the length of the corolla tube and the anther arrangement: Coffea with a short corolla tube and exserted style and anthers; Psilanthus with a long corolla tube and included anthers. However, these characteristics were not present in all species of either respective genus, making the two genera overwhelmingly similar in both morphology and genetic sequence. This transfer expanded Coffea from 104 species to 124, and extended its native distribution to tropical Asia and Australasia.
In 2014, the coffee genome was published, with more than 25,000 genes identified. This revealed that coffee plants make caffeine using a different set of genes from those found in tea, cacao and other such plants.
In 2017, a robust and almost fully resolved phylogeny of the entire genus was published. In addition to resolving the relationships of Coffea species, this study's results suggest Africa or Asia as the likely ancestral origin of Coffea and point to several independent radiations across Africa, Asia, and the Western Indian Ocean Islands.
In 2020 a technique of DNA fingerprinting, or genetic authentication of plant material was proven effective for coffee. For the study, scientists used DNA extraction and SSR marker analysis. This technique or ones similar may allow for several improvements to coffee production such as improved information for farmers as to the susceptibility of their coffee plants to pests and disease, a professionalized coffee seed system, and transparency and traceability for buyers of green, un-roasted coffee. | [

5,931 | Cycling | Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other type of cycle. It encompasses the use of human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport.
Cycling became popularlised in Europe and North America in the latter part and especially the last decade of the 19th century. Today, over 50 percent of the human population knows how to ride a bike.
The bicycle has been used as a method of reconnaissance as well as transporting soldiers and supplies to combat zones. In this it has taken over many of the functions of horses in warfare. In the Second Boer War, both sides used bicycles for scouting. In World War I, France, Germany, Australia and New Zealand used bicycles to move troops. In its 1937 invasion of China, Japan employed some 50,000 bicycle troops, and similar forces were instrumental in Japan's march or "roll" through Malaya in World War II. Germany used bicycles again in World War II, while the British employed airborne "Cycle-commandos" with folding bikes.
In the Vietnam War, communist forces used bicycles extensively as cargo carriers along the Ho Chi Minh Trail.
The last country known to maintain a regiment of bicycle troops was Switzerland, which disbanded its last unit in 2003.
In many countries, the most commonly used vehicle for road transport is a utility bicycle. These have frames with relaxed geometry, protecting the rider from shocks of the road and easing steering at low speeds. Utility bicycles tend to be equipped with accessories such as mudguards, pannier racks and lights, which extends their usefulness on a daily basis. Since the bicycle is so effective as a means of transportation, various companies have developed methods of carrying anything from the weekly shop to children on bicycles. Certain countries rely heavily on bicycles and their culture has developed around the bicycle as a primary form of transport. In Europe, Denmark and the Netherlands have the most bicycles per capita and most often use bicycles for everyday transport.
Road bikes tend to have a more upright shape and a shorter wheelbase, which make the bike more mobile but harder to ride slowly. The design, coupled with low or dropped handlebars, requires the rider to bend forward more, making use of stronger muscles (particularly the gluteus maximus) and reducing air resistance at high speed.
Road bikes are designed for speed and efficiency on paved roads. They are characterized by their lightweight frames, skinny tires, drop handlebars, and narrow saddles. Road bikes are ideal for racing, long-distance riding, and fitness training.
The price of a new bicycle can range from US$50 to more than US$20,000 (the highest priced bike in the world is the custom Madone by Damien Hirst, sold at US$500,000), depending on quality, type and weight (the most exotic road bicycles can weigh as little as 3.2 kg (7 lb)). However, UCI regulations stipulate a legal race bike cannot weigh less than 6.8 kg (14.99 lbs). Being measured for a bike and taking it for a test ride are recommended before buying.
The drivetrain components of the bike should also be considered. A middle grade dérailleur is sufficient for a beginner, although many utility bikes are equipped with hub gears. If the rider plans a significant amount of hillclimbing, a triple-chainrings crankset gear system may be preferred. Otherwise, the relatively lighter, simpler, and less expensive double chainring is preferred, even on high-end race bikes. Much simpler fixed wheel bikes are also available.
Many road bikes, along with mountain bikes, include clipless pedals to which special shoes attach, via a cleat, enabling the rider to pull on the pedals as well as push. Other possible accessories for the bicycle include front and rear lights, bells or horns, child carrying seats, cycling computers with GPS, locks, bar tape, fenders (mud-guards), baggage racks, baggage carriers and pannier bags, water bottles and bottle cages.
For basic maintenance and repairs cyclists can carry a pump (or a CO2 cartridge), a puncture repair kit, a spare inner tube, and tire levers and a set of allen keys. Cycling can be more efficient and comfortable with special shoes, gloves, and shorts. In wet weather, riding can be more tolerable with waterproof clothes, such as cape, jacket, trousers (pants) and overshoes and high-visibility clothing is advisable to reduce the risk from motor vehicle users.
Items legally required in some jurisdictions, or voluntarily adopted for safety reasons, include bicycle helmets, generator or battery operated lights, reflectors, and audible signalling devices such as a bell or horn. Extras include studded tires and a bicycle computer.
Bikes can also be heavily customized, with different seat designs and handle bars, for example. Gears can also be customized to better suit the rider's strength in relation to the terrain.
Many schools and police departments run educational programs to instruct children in bicycle handling skills, especially to introduce them to the rules of the road as they apply to cyclists. In some countries these may be known as bicycle rodeos, or operated as schemes such as Bikeability in the UK. Education for adult cyclists is available from organizations such as the League of American Bicyclists.
Beyond simply riding, another skill is riding efficiently and safely in traffic. One popular approach to riding in motor vehicle traffic is vehicular cycling, occupying road space as car does. Alternately, in countries such as Denmark and the Netherlands, where cycling is popular, cyclists are often segregated into bike lanes at the side of, or more often separate from, main highways and roads. Many primary schools participate in the national road test in which children individually complete a circuit on roads near the school while being observed by testers.
Cyclists, pedestrians and motorists make different demands on road design which may lead to conflicts. Some jurisdictions give priority to motorized traffic, for example setting up one-way street systems, free-right turns, high capacity roundabouts, and slip roads. Others share priority with cyclists so as to encourage more cycling by applying varying combinations of traffic calming measures to limit the impact of motorized transport, and by building bike lanes, bike paths and cycle tracks. The provision of cycling infrastructure varies widely between cities and countries, particularly since cycling for transportation almost entirely occurs in public streets. And, the development of computer vision and street view imagery has provided significant potential to assess infrastructure for cyclists.
In jurisdictions where motor vehicles were given priority, cycling has tended to decline while in jurisdictions where cycling infrastructure was built, cycling rates have remained steady or increased. Occasionally, extreme measures against cycling may occur. In Shanghai, where bicycles were once the dominant mode of transport, bicycle travel on a few city roads was banned temporarily in December 2003.
In areas in which cycling is popular and encouraged, cycle-parking facilities using bicycle stands, lockable mini-garages, and patrolled cycle parks are used to reduce theft. Local governments promote cycling by permitting bicycles to be carried on public transport or by providing external attachment devices on public transport vehicles. Conversely, an absence of secure cycle-parking is a recurring complaint by cyclists from cities with low modal share of cycling.
Extensive cycling infrastructure may be found in some cities. Such dedicated paths in some cities often have to be shared with in-line skaters, scooters, skateboarders, and pedestrians. Dedicated cycling infrastructure is treated differently in the law of every jurisdiction, including the question of liability of users in a collision. There is also some debate about the safety of the various types of separated facilities.
Bicycles are considered a sustainable mode of transport, especially suited for urban use and relatively shorter distances when used for transport (compared to recreation). Case studies and good practices (from European cities and some worldwide examples) that promote and stimulate this kind of functional cycling in cities can be found at Eltis, Europe's portal for local transport.
A number of cities, including Paris, London and Barcelona, now have successful bike hire schemes designed to help people cycle in the city. Typically these feature utilitarian city bikes which lock into docking stations, released on payment for set time periods. Costs vary from city to city. In London, initial hire access costs £2 per day. The first 30 minutes of each trip is free, with £2 for each additional 30 minutes until the bicycle is returned.
In the Netherlands, many roads have one or two separate cycleways alongside them, or cycle lanes marked on the road. On roads where adjacent bike paths or cycle tracks exist, the use of these facilities is compulsory, and cycling on the main carriageway is not permitted. Some 35,000 km of cycle-track has been physically segregated from motor traffic, equal to a quarter of the country's entire 140,000 km road network. A quarter of all the trips in the country made on bicycles, one quarter of them to work. Even the prime minister is going to work by bicycle, when weather permits. This saves the life of 6,000 citizens per year, prolong the life expectancy by 6 months, save the country 20 million dollars per year, and prevent 150 grams of CO2 to be emitted per kilometer of cycling, on each bicycle.
Utility cycling refers both to cycling as a mode of daily commuting transport as well as the use of a bicycle in a commercial activity, mainly to transport goods, mostly accomplished in an urban environment.
The postal services of many countries have long relied on bicycles. The British Royal Mail first started using bicycles in 1880; now bicycle delivery fleets include 37,000 in the UK, 25,700 in Germany, 10,500 in Hungary and 7000 in Sweden. In Australia, Australia Post has also reintroduced bicycle postal deliveries on some routes due to an inability to recruit sufficient licensed riders willing to use their uncomfortable motorbikes. The London Ambulance Service has recently introduced bicycling paramedics, who can often get to the scene of an incident in Central London more quickly than a motorized ambulance.
The use of bicycles by police has been increasing, since they provide greater accessibility to bicycle and pedestrian zones and allow access when roads are congested. In some cases, bicycle officers have been used as a supplement or a replacement for horseback officers.
Bicycles enjoy substantial use as general delivery vehicles in many countries. In the UK and North America, as their first jobs, generations of teenagers have worked at delivering newspapers by bicycle. London has many delivery companies that use bicycles with trailers. Most cities in the West, and many outside it, support a sizeable and visible industry of cycle couriers who deliver documents and small packages. In India, many of Mumbai's Dabbawalas use bicycles to deliver home cooked lunches to the city's workers. In Bogotá, Colombia the city's largest bakery recently replaced most of its delivery trucks with bicycles. Even the car industry uses bicycles. At the huge Mercedes-Benz factory in Sindelfingen, Germany workers use bicycles, color-coded by department, to move around the factory.
Bicycles are used for recreation at all ages. Bicycle touring, also known as cyclotourism, involves touring and exploration or sightseeing by bicycle for leisure. Bicycle tourism has been one of the most popular sports for recreational benefit. A brevet or randonnée is an organized long-distance ride.
One popular Dutch pleasure is the enjoyment of relaxed cycling in the countryside of the Netherlands. The land is very flat and full of public bicycle trails and cycle tracks where cyclists are not bothered by cars and other traffic, which makes it ideal for cycling recreation. Many Dutch people subscribe every year to an event called fietsvierdaagse — four days of organised cycling through the local environment. Paris–Brest–Paris (PBP), which began in 1891, is the oldest bicycling event still run on a regular basis on the open road, covers over 1,200 km (746 mi) and imposes a 90-hour time limit. Similar if smaller institutions exist in many countries.
A study conducted in Taiwan improved the environmental quality for bicyclist tourists which demonstrated greater health benefits in tourists and even in natives. The number of bicyclists in Taiwan increased from 700,000 in 2008 to 5.1 million in 2017. Thus, this resulted in more and safer bicycle routes to be established. When cycling, cyclists take into account the safety on the road, bicycle lanes, smooth roads, diverse scenery, and ride length. Thus, the environment plays a huge role in people's decision factor to use bicycle touring more. This study used many questionnaires and conducted statistical analysis to come up with the conclusion of cyclists' top 5 factors that they consider before making a decision to bike are: safety, lighting facility, design of lanes, the surrounding landscape, and how clean the environment is. Thus, after improving these 5 factors, they found much more recreational benefits to bicycle tourism.
Many cycling clubs hold organized rides in which bicyclists of all levels participate. The typical organized ride starts with a large group of riders, called the mass, bunch or even peloton. This will thin out over the course of the ride. Many riders choose to ride together in groups of the same skill level to take advantage of drafting.
Most organized rides, for example cyclosportives (or gran fondos), Challenge Rides or reliability trials, and hill climbs include registration requirements and will provide information either through the mail or online concerning start times and other requirements. Rides usually consist of several different routes, sorted by mileage, and with a certain number of rest stops that usually include refreshments, first aid and maintenance tools. Routes can vary by as much as 100 miles (160 km).
Some organized rides are entirely social events. One example is the monthly San Jose Bike Party which can reach attendance of one to two thousand riders in Summer months.
Mountain biking began in the 1970s, originally as a downhill sport, practised on customized cruiser bicycles around Mount Tamalpais. Most mountain biking takes place on dirt roads, trails and in purpose-built parks. Downhill mountain biking has just evolved in the recent years and is performed at places such as Whistler Mountain Bike Park. Slopestyle, a form of downhill, is when riders do tricks such as tailwhips, 360s, backflips and front flips. There are several disciplines of mountain biking besides downhill, including: cross country (often referred to as XC), all mountain, trail, free ride, and newly popular enduro.
In 2020, due to COVID-19, mountain bikes saw a surge in popularity in the US, with some vendors reporting that they were sold out of bikes under US$1000.
The Marching and Cycling Band HHK from Haarlem (the Netherlands) is one of the few marching bands around the world which also performs on bicycles.
Shortly after the introduction of bicycles, competitions developed independently in many parts of the world. Early races involving boneshaker style bicycles were predictably fraught with injuries. Large races became popular during the 1890s "Golden Age of Cycling", with events across Europe, and in the U.S. and Japan as well. At one point, almost every major city in the US had a velodrome or two for track racing events, however since the middle of the 20th century cycling has become a minority sport in the US whilst in Continental Europe it continues to be a major sport, particularly in the United Kingdom, France, Belgium, Italy and Spain. The most famous of all bicycle races is the Tour de France. This began in 1903, and continues to capture the attention of the sporting world.
In 1899, Charles Minthorn Murphy became the first man to ride his bicycle a mile in under a minute (hence his nickname, Mile-a-Minute Murphy), which he did by drafting a locomotive at New York's Long Island.
As the bicycle evolved its various forms, different racing formats developed. Road races may involve both team and individual competition, and are contested in various ways. They range from the one-day road race, criterium, and time trial to multi-stage events like the Tour de France and its sister events which make up cycling's Grand Tours. Recumbent bicycles were banned from bike races in 1934 after Marcel Berthet set a new hour record in his Velodyne streamliner (49.992 km on 18 November 1933). Track bicycles are used for track cycling in Velodromes, while cyclo-cross races are held on outdoor terrain, including pavement, grass, and mud. Cyclocross races feature human-made features such as small barriers which riders either bunny hop over or dismount and walk over. Time trial races, another form of road racing require a rider to ride against the clock. Time trials can be performed as a team or as a single rider. Bikes are changed for time trial races, using aero bars. In the past decade, mountain bike racing has also reached international popularity and is even an Olympic sport.
Professional racing organizations place limitations on the bicycles that can be used in the races that they sanction. For example, the Union Cycliste Internationale, the governing body of international cycle sport (which sanctions races such as the Tour de France), decided in the late 1990s to create additional rules which prohibit racing bicycles weighing less than 6.8 kilograms (14.96 pounds). The UCI rules also effectively ban some bicycle frame innovations (such as the recumbent bicycle) by requiring a double triangle structure.
Many broad and correlated themes run in bicycle activism: one is about advocating the bicycle as an alternative mode of transport, and another is about the creation of conditions to permit and/or encourage bicycle use, both for utility and recreational cycling. Although the first emphasizes the potential for energy and resource conservation and health benefits gained from cycling versus automobile use, is relatively undisputed, the second is the subject of much debate.
It is generally agreed that improved local and inter-city rail services and other methods of mass transportation (including greater provision for cycle carriage on such services) create conditions to encourage bicycle use. However, there are different opinions on the role of various types of cycling infrastructure in building bicycle-friendly cities and roads.
Some bicycle activists (including some traffic management advisers) seek the construction of bike paths, cycle tracks and bike lanes for journeys of all lengths and point to their success in promoting safety and encouraging more people to cycle. Some activists, especially those from the vehicular cycling tradition, view the safety, practicality, and intent of such facilities with suspicion. They favor a more holistic approach based on the 4 'E's; education (of everyone involved), encouragement (to apply the education), enforcement (to protect the rights of others), and engineering (to facilitate travel while respecting every person's equal right to do so). Some groups offer training courses to help cyclists integrate themselves with other traffic.
Critical Mass is an event typically held on the last Friday of every month in cities around the world where bicyclists take to the streets en masse. While the ride was founded with the idea of drawing attention to how unfriendly the city was to bicyclists, the leaderless structure of Critical Mass makes it impossible to assign it any one specific goal. In fact, the purpose of Critical Mass is not formalized beyond the direct action of meeting at a set location and time and traveling as a group through city streets.
There is a long-running cycle helmet debate among activists. The most heated controversy surrounds the topic of compulsory helmet use.
It is paradoxical that in many developing countries cycling is in decline as bicycles are replaced by motorbikes and cars, while in many developed countries cycling is on the rise.
Within western societies the demographic of those who cycle is often not representative of broader society. Research by TfL in London, UK, suggests that cyclists in London are typically 'white, under 40, male, with medium to high household income.' Studies from large-scale representative data from Germany show that people with higher levels of education cycle substantially more often than those with lower levels of education. Even for trips of the same distance and among people from the same city with the same income level, those with higher education cycle more. As a result, there are various forms of activism focused on diversifying the cycling community. Inspired by the Black Lives Matter movement are organizations such as Street Riders NYC that seek to protest while on bicycles about systemic racism and police brutality. An incidental experience for Street Riders NYC protest participants is the inequity in where safe bicycling infrastructure exists by neighbourhood, which is interpreted as a form of classism within cycling and urbanism. The bicycle has acted as a means for women's liberation and thus has links to feminism.
Cyclists form associations, both for specific interests (trails development, road maintenance, bike maintenance, urban design, racing clubs, touring clubs, etc.) and for more global goals (energy conservation, pollution reduction, promotion of fitness). Some bicycle clubs and national associations became prominent advocates for improvements to roads and highways. In the United States, the League of American Wheelmen lobbied for the improvement of roads in the last part of the 19th century, founding and leading the national Good Roads Movement. Their model for political organization, as well as the paved roads for which they argued, facilitated the growth of the automobile.
In Europe, the European Cyclists' Federation represents around 70 local, regional and national civil society organisations across more than 40 countries that work to promote cycling as a mode of transport and leisure.
As a sport, cycling is governed internationally by the Union Cycliste Internationale in Switzerland, USA Cycling (merged with the United States Cycling Federation in 1995) in the United States, (for upright bicycles) and by the International Human Powered Vehicle Association (for other HPVs, or human-powered vehicles). Cycling for transport and touring is promoted on a European level by the European Cyclists' Federation, with associated members from Great Britain, Japan and elsewhere. Regular conferences on cycling as transport are held under the auspices of Velo City; global conferences are coordinated by Velo Mondial.
Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances.
Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air and noise pollution, reduced greenhouse gas emissions, and greatly reduced traffic congestion. These have a lower financial cost for users as well as for society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve.
Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadricycles) for the rider to have certain level of basic skill to remain upright, the reduced protection in crashes in comparison to motor vehicles, often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.
Cycling provides a variety of health benefits and reduces the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles. Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery. Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.
The health benefits of cycling outweigh the risks, when cycling is compared to a sedentary lifestyle. A Dutch study found that cycling can extend lifespans by up to 14 months, but the risks equated to a reduced lifespan of 40 days or less. Mortality rate reduction was found to be directly correlated to the average time spent cycling, totaling to approximately 6500 deaths prevented by cycling. Cycling in the Netherlands is often safer than in other parts of the world, so the risk-benefit ratio will be different in other regions. Overall, benefits of cycling or walking have been shown to exceed risks by ratios of 9:1 to 96:1 when compared with no exercise at all, including a wide variety of physical and mental outcomes.
The physical exercise gained from cycling is generally linked with increased health and well-being. According to the World Health Organization (WHO), physical inactivity is second only to tobacco smoking as a health risk in developed countries, and is associated with 20-30% increased risk of various cancers, heart disease, and diabetes and tens of billions of dollars of healthcare costs. The WHO's 2009 report suggests that increasing physical activity is a public health "best buy", and that cycling is a "highly suitable activity" for this purpose. The charity Sustrans reports that investment in cycling provision can give a 20:1 return from health and other benefits. It has been estimated that, on average, approximately 20 life-years are gained from the health benefits of road bicycling for every life-year lost through injury.
Bicycles are often used by people seeking to improve their fitness and cardiovascular health. Recent studies on the use of cycling for commutes have shown that it reduces the risk of cardiovascular outcomes by 11%, with slightly more risk reduction in women than in men. In addition, cycling is especially helpful for those with arthritis of the lower limbs who are unable to pursue sports that cause impact to the knees and other joints. Since cycling can be used for the practical purpose of transportation, there can be less need for self-discipline to exercise.
Cycling while seated is a relatively non-weight bearing exercise that, like swimming, does little to promote bone density. Cycling up and out of the saddle, on the other hand, does a better job by transferring more of the rider's body weight to the legs. However, excessive cycling while standing can cause knee damage It used to be thought that cycling while standing was less energy efficient, but recent research has proven this not to be true. Other than air resistance, there is no wasted energy from cycling while standing, if it is done correctly.
Cycling on a stationary cycle is frequently advocated as a suitable exercise for rehabilitation, particularly for lower limb injury, owing to the low impact which it has on the joints. In particular, cycling is commonly used within knee rehabilitation programs, to strengthen the quadriceps muscles with minimal stress on the knee ligaments. Further stress of the knee can be relieved by changing seat heights and pedal position to improve the rehabilitation. Cycling is also used for rehabilitation after hip surgery to manage soft-tissue healing, control swelling and pain, and allow a larger range of motion to the nearby muscles earlier during recovery. As a result, many institutions have established a rehabilitation protocol that involves stationary cycling as part of the recovery process. One such protocol offered by Mayo Clinic recommends 2–4 weeks of cycling on an upright stationary bike following hip arthroscopy, starting from 5 minutes per session and slowly increasing to 30 minutes per session. The goal of these sessions are to reduce joint inflammation and maintain the widest range of motion possible with limited pain.
As a response to the increased global sedentary lifestyles and consequent overweight and obesity, one response that has been adopted by many organizations concerned with health and environment is the promotion of Active travel, which seeks to promote walking and cycling as safe and attractive alternatives to motorized transport. Given that many journeys are for relatively short distances, there is considerable scope to replace car use with walking or cycling, though in many settings this may require some infrastructure modification, particularly to attract the less experienced and confident.
An Italian study assessed the impact of cycling for commute on major non-communicable diseases and public healthcare costs. Using a health economic assessment model, the study found a lower incidence of type 2 diabetes, acute myocardial infarction, and stroke in individuals that cycled compared to those that did not actively commute. This model estimated that public healthcare costs would reduce by 5% over a 10-year period.
Illinois designated cycling as its official state exercise in 2007.
The effects of cycling on overall mental health have often been studied. A European study surveying participants from seven cities about self-perceived health based on primary modes of transportation reported favorable results in the bicycle use population. The bicycle use group reported predominantly good self-perceived health, less perceived stress, better mental health, better vitality, and less loneliness. The study attributed these results to possible economic benefits and senses of both independence and identity as a member of a cyclist community. An English study recruiting non-cyclist older adults aged 50 to 83 to participate as either conventional pedal bike cyclists, electrically assisted e-bike cyclists, or a non-cyclist control group in outdoor trails measured cognitive function through executive function, spatial reasoning, and memory tests and well-being through questionnaires. The study did not find significant differences in spatial reasoning or memory tests. It did, however, find that both cyclists groups had improved executive function and well-being, both with greater improvement in the e-bike group. This suggested that non-physical factors of cycling such as independence, engagement with the outdoor environment, and mobility play a greater role in improving mental health.
A 15-month randomized controlled trial in the U.S. examined the impact of self-paced cycling on cognitive function in institutionalized older adults without cognitive impairment. Researchers used three cognitive assessments: Mini-Mental State Examination (MMSE), Fuld object memory evaluation, and symbol digit modality test. The study found that long-term cycling for at least 15 minutes per day in older adults without cognitive impairment had a protective effect on cognition and attention.
Cycling has also been shown to be effective adjunct therapy in certain mental health conditions.
Cycling suffers from a perception that it is unsafe. This perception is not always backed by hard numbers, because of under reporting of crashes and lack of bicycle use data (amount of cycling, kilometers cycled) which make it hard to assess the risk and monitor changes in risks. In the UK, fatality rates per mile or kilometre are slightly less than those for walking. In the US, bicycling fatality rates are less than 2/3 of those walking the same distance. However, in the UK for example the fatality and serious injury rates per hour of travel are just over double for cycling than those for walking.
Despite the risk factors associated with bicycling, cyclists have a lower overall mortality rate when compared to other groups. A Danish study in 2000 found that even after adjustment for other risk factors, including leisure time physical activity, those who did not cycle to work experienced a 39% higher mortality rate than those who did.
Injuries (to cyclists, from cycling) can be divided into two types:
Acute physical trauma includes injuries to the head and extremities resulting from falls and collisions. Most cycle deaths result from a collision with a car or heavy goods vehicle. Drivers are at fault in the majority of these crashes. Segregated cycling infrastructure reduces the rate of crashes between bicycles and motor vehicles.
Although a majority of bicycle collisions occur during the day, bicycle lighting is recommended for safety when bicycling at night to increase visibility.
Of a study of 518 cyclists, a large majority reported at least one overuse injury, with over one third requiring medical treatment. The most common injury sites were the neck (48.8%) and the knees (41.7%), as well as the groin/buttocks (36.1%), hands (31.1%), and back (30.3%). Women were more likely to suffer from neck and shoulder pain than men.
Many cyclists suffer from overuse injuries to the knees, affecting cyclists at all levels. These are caused by many factors:
Overuse injuries, including chronic nerve damage at weight bearing locations, can occur as a result of repeatedly riding a bicycle for extended periods of time. Damage to the ulnar nerve in the palm, carpal tunnel in the wrist, the genitourinary tract or bicycle seat neuropathy may result from overuse. Recumbent bicycles are designed on different ergonomic principles and eliminate pressure from the saddle and handlebars, due to the relaxed riding position.
Note that overuse is a relative term, and capacity varies greatly between individuals. Someone starting out in cycling must be careful to increase length and frequency of cycling sessions slowly, starting for example at an hour or two per day, or a hundred miles or kilometers per week. Bilateral muscular pain is a normal by-product of the training process, whereas unilateral pain may reveal "exercise-induced arterial endofibrosis". Joint pain and numbness are also early signs of overuse injury.
A Spanish study of top triathletes found those who cover more than 186 miles (300 km) a week on their bikes have less than 4% normal looking sperm, where normal adult males would be expected to have from 15% to 20%.
Much work has been done to investigate optimal bicycle saddle shape, size and position, and negative effects of extended use of less than optimal seats or configurations.
Excessive saddle height can cause posterior knee pain, while setting the saddle too low can cause pain in the anterior of the knee. An incorrectly fitted saddle may eventually lead to muscle imbalance. A 25 to 35-degree knee angle is recommended to avoid an overuse injury.
Although cycling is beneficial to health, men can be negatively affected by cycling more than three hours a week due to the significant weight on their perineum, an area located between the scrotum and the anus which hold some of the nerves and arteries that pass to the penis. This weight for continuous hours a week can cause men to experience numbness or tingling which can lead to them losing the ability to achieve an erection due to reduced blood flow; which 13% of males did experience in a study by Norwegian researchers who gathered data from 160 men participating in a long-distance bike tour. Fitting a proper sized seat can prevent this effect. In extreme cases, pudendal nerve entrapment can be a source of intractable perineal pain. Some cyclists with induced pudendal nerve pressure neuropathy gained relief from improvements in saddle position and riding techniques.
The National Institute for Occupational Safety and Health (NIOSH) has investigated the potential health effects of prolonged bicycling in police bicycle patrol units, including the possibility that some bicycle saddles exert excessive pressure on the urogenital area of cyclists, restricting blood flow to the genitals. Their study found that using bicycle seats without protruding noses reduced pressure on the groin by at least 65% and significantly reduced the number of cases of urogenital paresthesia. A follow-up found that 90% of bicycle officers who tried the no-nose seat were using it six months later. NIOSH recommends that riders use a no-nose bicycle seat for workplace bicycling.
Despite rumors to the contrary, there is no scientific evidence linking cycling with testicular cancer.
One concern is that riding in traffic may expose the cyclist to higher levels of air pollution, especially if he or she travels on or along busy roads. Some authors have claimed this to be untrue, showing that the pollutant and irritant count within cars is consistently higher, presumably because of limited circulation of air within the car and due to the air intake being directly in the stream of other traffic. Other authors have found small or inconsistent differences in concentrations but claim that exposure of cyclists is higher due to increased minute ventilation and is associated with minor biological changes. A 2010 study estimated that the gained life expectancy from the health benefits of cycling (approximately 3–14 months gained) greatly exceeded the lost life expectancy from air pollution (approximately 0.8–40 days lost). However, a systematic review comparing the effects of air pollution exposure on the health of cyclists was conducted, but the authors concluded that the differing methodologies and measuring parameters of each study made it difficult to compare results and suggested a more holistic approach was needed to accomplish this. The significance of the associated health effect, if any, is unclear but probably much smaller than the health impacts associated with accidents and the health benefits derived from additional physical activity. | [

They favor a more holistic approach based on the 4 'E's; education (of everyone involved), encouragement (to apply the education), enforcement (to protect the rights of others), and engineering (to facilitate travel while respecting every person's equal right to do so). Some groups offer training courses to help cyclists integrate themselves with other traffic.",

"text": "Within western societies the demographic of those who cycle is often not representative of broader society. Research by TfL in London, UK, suggests that cyclists in London are typically 'white, under 40, male, with medium to high household income.' Studies from large-scale representative data from Germany show that people with higher levels of education cycle substantially more often than those with lower levels of education. Even for trips of the same distance and among people from the same city with the same income level, those with higher education cycle more. As a result, there are various forms of activism focused on diversifying the cycling community. Inspired by the Black Lives Matter movement are organizations such as Street Riders NYC that seek to protest while on bicycles about systemic racism and police brutality. An incidental experience for Street Riders NYC protest participants is the inequity in where safe bicycling infrastructure exists by neighbourhood, which is interpreted as a form of classism within cycling and urbanism. The bicycle has acted as a means for women's liberation and thus has links to feminism.",

Further stress of the knee can be relieved by changing seat heights and pedal position to improve the rehabilitation. Cycling is also used for rehabilitation after hip surgery to manage soft-tissue healing, control swelling and pain, and allow a larger range of motion to the nearby muscles earlier during recovery. As a result, many institutions have established a rehabilitation protocol that involves stationary cycling as part of the recovery process. One such protocol offered by Mayo Clinic recommends 2–4 weeks of cycling on an upright stationary bike following hip arthroscopy, starting from 5 minutes per session and slowly increasing to 30 minutes per session.

A 2010 study estimated that the gained life expectancy from the health benefits of cycling (approximately 3–14 months gained) greatly exceeded the lost life expectancy from air pollution (approximately 0.8–40 days lost). However, a systematic review comparing the effects of air pollution exposure on the health of cyclists was conducted, but the authors concluded that the differing methodologies and measuring parameters of each study made it difficult to compare results and suggested a more holistic approach was needed to accomplish this.

5,932 | Carbohydrate | A carbohydrate (/ˌkɑːrboʊˈhaɪdreɪt/) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula Cm(H2O)n (where m may or may not be different from n), which does not mean the H has covalent bonds with O (for example with CH2O, H has a covalent bond with C but not with O). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde and acetic acid).
The term is most common in biochemistry, where it is a synonym of saccharide (from Ancient Greek σάκχαρον (sákkharon) 'sugar'), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular weight) carbohydrates, are commonly referred to as sugars. While the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix -ose, which was originally taken from the word glucose (from Ancient Greek γλεῦκος (gleûkos) 'wine, must'), and is used for almost all sugars, e.g. fructose (fruit sugar), sucrose (cane or beet sugar), ribose, lactose (milk sugar), etc.
Carbohydrates perform numerous roles in living organisms. Polysaccharides serve as an energy store (e.g. starch and glycogen) and as structural components (e.g. cellulose in plants and chitin in arthropods). The 5-carbon monosaccharide ribose is an important component of coenzymes (e.g. ATP, FAD and NAD) and the backbone of the genetic molecule known as RNA. The related deoxyribose is a component of DNA. Saccharides and their derivatives include many other important biomolecules that play key roles in the immune system, fertilization, preventing pathogenesis, blood clotting, and development.
Carbohydrates are central to nutrition and are found in a wide variety of natural and processed foods. Starch is a polysaccharide and is abundant in cereals (wheat, maize, rice), potatoes, and processed food based on cereal flour, such as bread, pizza or pasta. Sugars appear in human diet mainly as table sugar (sucrose, extracted from sugarcane or sugar beets), lactose (abundant in milk), glucose and fructose, both of which occur naturally in honey, many fruits, and some vegetables. Table sugar, milk, or honey are often added to drinks and many prepared foods such as jam, biscuits and cakes.
Cellulose, a polysaccharide found in the cell walls of all plants, is one of the main components of insoluble dietary fiber. Although it is not digestible by humans, cellulose and insoluble dietary fiber generally help maintain a healthy digestive system by facilitating bowel movements. Other polysaccharides contained in dietary fiber include resistant starch and inulin, which feed some bacteria in the microbiota of the large intestine, and are metabolized by these bacteria to yield short-chain fatty acids.
In scientific literature, the term "carbohydrate" has many synonyms, like "sugar" (in the broad sense), "saccharide", "ose", "glucide", "hydrate of carbon" or "polyhydroxy compounds with aldehyde or ketone". Some of these terms, especially "carbohydrate" and "sugar", are also used with other meanings.
In food science and in many informal contexts, the term "carbohydrate" often means any food that is particularly rich in the complex carbohydrate starch (such as cereals, bread and pasta) or simple carbohydrates, such as sugar (found in candy, jams, and desserts). This informality is sometimes confusing since it confounds chemical structure and digestibility in humans.
Often in lists of nutritional information, such as the USDA National Nutrient Database, the term "carbohydrate" (or "carbohydrate by difference") is used for everything other than water, protein, fat, ash, and ethanol. This includes chemical compounds such as acetic or lactic acid, which are not normally considered carbohydrates. It also includes dietary fiber which is a carbohydrate but which does not contribute food energy in humans, even though it is often included in the calculation of total food energy just as though it did (i.e., as if it were a digestible and absorbable carbohydrate such as a sugar). In the strict sense, "sugar" is applied for sweet, soluble carbohydrates, many of which are used in human food.
The history of the discovery regarding carbohydrates dates back around 10,000 years ago in Papua New Guinea during the cultivation of Sugarcane during the Neolithic agricultural revolution . The term "carbohydrate" was first proposed by German chemist Carl Schmidt (chemist) in 1844. In 1856, glycogen, a form of carbohydrate storage in animal livers, was discovered by French physiologist Claude Bernard.
Formerly the name "carbohydrate" was used in chemistry for any compound with the formula Cm (H2O)n. Following this definition, some chemists considered formaldehyde (CH2O) to be the simplest carbohydrate, while others claimed that title for glycolaldehyde. Today, the term is generally understood in the biochemistry sense, which excludes compounds with only one or two carbons and includes many biological carbohydrates which deviate from this formula. For example, while the above representative formulas would seem to capture the commonly known carbohydrates, ubiquitous and abundant carbohydrates often deviate from this. For example, carbohydrates often display chemical groups such as: N-acetyl (e.g. chitin), sulfate (e.g. glycosaminoglycans), carboxylic acid and deoxy modifications (e.g. fucose and sialic acid).
Natural saccharides are generally built of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more. A typical monosaccharide has the structure H–(CHOH)x(C=O)–(CHOH)y–H, that is, an aldehyde or ketone with many hydroxyl groups added, usually one on each carbon atom that is not part of the aldehyde or ketone functional group. Examples of monosaccharides are glucose, fructose, and glyceraldehydes. However, some biological substances commonly called "monosaccharides" do not conform to this formula (e.g. uronic acids and deoxy-sugars such as fucose) and there are many chemicals that do conform to this formula but are not considered to be monosaccharides (e.g. formaldehyde CH2O and inositol (CH2O)6).
The open-chain form of a monosaccharide often coexists with a closed ring form where the aldehyde/ketone carbonyl group carbon (C=O) and hydroxyl group (–OH) react forming a hemiacetal with a new C–O–C bridge.
Monosaccharides can be linked together into what are called polysaccharides (or oligosaccharides) in a large variety of ways. Many carbohydrates contain one or more modified monosaccharide units that have had one or more groups replaced or removed. For example, deoxyribose, a component of DNA, is a modified version of ribose; chitin is composed of repeating units of N-acetyl glucosamine, a nitrogen-containing form of glucose.
Carbohydrates are polyhydroxy aldehydes, ketones, alcohols, acids, their simple derivatives and their polymers having linkages of the acetal type. They may be classified according to their degree of polymerization, and may be divided initially into three principal groups, namely sugars, oligosaccharides and polysaccharides.
Monosaccharides are the simplest carbohydrates in that they cannot be hydrolyzed to smaller carbohydrates. They are aldehydes or ketones with two or more hydroxyl groups. The general chemical formula of an unmodified monosaccharide is (C•H2O)n, literally a "carbon hydrate". Monosaccharides are important fuel molecules as well as building blocks for nucleic acids. The smallest monosaccharides, for which n=3, are dihydroxyacetone and D- and L-glyceraldehydes.
The α and β anomers of glucose. Note the position of the hydroxyl group (red or green) on the anomeric carbon relative to the CH2OH group bound to carbon 5: they either have identical absolute configurations (R,R or S,S) (α), or opposite absolute configurations (R,S or S,R) (β).
Monosaccharides are classified according to three different characteristics: the placement of its carbonyl group, the number of carbon atoms it contains, and its chiral handedness. If the carbonyl group is an aldehyde, the monosaccharide is an aldose; if the carbonyl group is a ketone, the monosaccharide is a ketose. Monosaccharides with three carbon atoms are called trioses, those with four are called tetroses, five are called pentoses, six are hexoses, and so on. These two systems of classification are often combined. For example, glucose is an aldohexose (a six-carbon aldehyde), ribose is an aldopentose (a five-carbon aldehyde), and fructose is a ketohexose (a six-carbon ketone).
Each carbon atom bearing a hydroxyl group (-OH), with the exception of the first and last carbons, are asymmetric, making them stereo centers with two possible configurations each (R or S). Because of this asymmetry, a number of isomers may exist for any given monosaccharide formula. Using Le Bel-van't Hoff rule, the aldohexose D-glucose, for example, has the formula (C·H2O)6, of which four of its six carbons atoms are stereogenic, making D-glucose one of 2=16 possible stereoisomers. In the case of glyceraldehydes, an aldotriose, there is one pair of possible stereoisomers, which are enantiomers and epimers. 1, 3-dihydroxyacetone, the ketose corresponding to the aldose glyceraldehydes, is a symmetric molecule with no stereo centers. The assignment of D or L is made according to the orientation of the asymmetric carbon furthest from the carbonyl group: in a standard Fischer projection if the hydroxyl group is on the right the molecule is a D sugar, otherwise it is an L sugar. The "D-" and "L-" prefixes should not be confused with "d-" or "l-", which indicate the direction that the sugar rotates plane polarized light. This usage of "d-" and "l-" is no longer followed in carbohydrate chemistry.
The aldehyde or ketone group of a straight-chain monosaccharide will react reversibly with a hydroxyl group on a different carbon atom to form a hemiacetal or hemiketal, forming a heterocyclic ring with an oxygen bridge between two carbon atoms. Rings with five and six atoms are called furanose and pyranose forms, respectively, and exist in equilibrium with the straight-chain form.
During the conversion from straight-chain form to the cyclic form, the carbon atom containing the carbonyl oxygen, called the anomeric carbon, becomes a stereogenic center with two possible configurations: The oxygen atom may take a position either above or below the plane of the ring. The resulting possible pair of stereoisomers is called anomers. In the α anomer, the -OH substituent on the anomeric carbon rests on the opposite side (trans) of the ring from the CH2OH side branch. The alternative form, in which the CH2OH substituent and the anomeric hydroxyl are on the same side (cis) of the plane of the ring, is called the β anomer.
Monosaccharides are the major fuel source for metabolism, being used both as an energy source (glucose being the most important in nature as it is the product of photosynthesis in plants) and in biosynthesis. When monosaccharides are not immediately needed, they are often converted to more space-efficient (i.e., less water-soluble) forms, often polysaccharides. In many animals, including humans, this storage form is glycogen, especially in liver and muscle cells. In plants, starch is used for the same purpose. The most abundant carbohydrate, cellulose, is a structural component of the cell wall of plants and many forms of algae. Ribose is a component of RNA. Deoxyribose is a component of DNA. Lyxose is a component of lyxoflavin found in the human heart. Ribulose and xylulose occur in the pentose phosphate pathway. Galactose, a component of milk sugar lactose, is found in galactolipids in plant cell membranes and in glycoproteins in many tissues. Mannose occurs in human metabolism, especially in the glycosylation of certain proteins. Fructose, or fruit sugar, is found in many plants and humans, it is metabolized in the liver, absorbed directly into the intestines during digestion, and found in semen. Trehalose, a major sugar of insects, is rapidly hydrolyzed into two glucose molecules to support continuous flight.
Two joined monosaccharides are called a disaccharide, the simplest kind of polysaccharide. Examples include sucrose and lactose. They are composed of two monosaccharide units bound together by a covalent bond known as a glycosidic linkage formed via a dehydration reaction, resulting in the loss of a hydrogen atom from one monosaccharide and a hydroxyl group from the other. The formula of unmodified disaccharides is C12H22O11. Although there are numerous kinds of disaccharides, a handful of disaccharides are particularly notable.
Sucrose, pictured to the right, is the most abundant disaccharide, and the main form in which carbohydrates are transported in plants. It is composed of one D-glucose molecule and one D-fructose molecule. The systematic name for sucrose, O-α-D-glucopyranosyl-(1→2)-D-fructofuranoside, indicates four things:
Lactose, a disaccharide composed of one D-galactose molecule and one D-glucose molecule, occurs naturally in mammalian milk. The systematic name for lactose is O-β-D-galactopyranosyl-(1→4)-D-glucopyranose. Other notable disaccharides include maltose (two D-glucoses linked α-1,4) and cellobiose (two D-glucoses linked β-1,4). Disaccharides can be classified into two types: reducing and non-reducing disaccharides. If the functional group is present in bonding with another sugar unit, it is called a reducing disaccharide or biose.
Carbohydrate consumed in food yields 3.87 kilocalories of energy per gram for simple sugars, and 3.57 to 4.12 kilocalories per gram for complex carbohydrate in most other foods. Relatively high levels of carbohydrate are associated with processed foods or refined foods made from plants, including sweets, cookies and candy, table sugar, honey, soft drinks, breads and crackers, jams and fruit products, pastas and breakfast cereals. Lower amounts of digestible carbohydrate are usually associated with unrefined foods as these foods have more fiber, including beans, tubers, rice, and unrefined fruit. Animal-based foods generally have the lowest carbohydrate levels, although milk does contain a high proportion of lactose.
Organisms typically cannot metabolize all types of carbohydrate to yield energy. Glucose is a nearly universal and accessible source of energy. Many organisms also have the ability to metabolize other monosaccharides and disaccharides but glucose is often metabolized first. In Escherichia coli, for example, the lac operon will express enzymes for the digestion of lactose when it is present, but if both lactose and glucose are present the lac operon is repressed, resulting in the glucose being used first (see: Diauxie). Polysaccharides are also common sources of energy. Many organisms can easily break down starches into glucose; most organisms, however, cannot metabolize cellulose or other polysaccharides like chitin and arabinoxylans. These carbohydrate types can be metabolized by some bacteria and protists. Ruminants and termites, for example, use microorganisms to process cellulose. Even though these complex carbohydrates are not very digestible, they represent an important dietary element for humans, called dietary fiber. Fiber enhances digestion, among other benefits.
The Institute of Medicine recommends that American and Canadian adults get between 45 and 65% of dietary energy from whole-grain carbohydrates. The Food and Agriculture Organization and World Health Organization jointly recommend that national dietary guidelines set a goal of 55–75% of total energy from carbohydrates, but only 10% directly from sugars (their term for simple carbohydrates). A 2017 Cochrane Systematic Review concluded that there was insufficient evidence to support the claim that whole grain diets can affect cardiovascular disease.
Nutritionists often refer to carbohydrates as either simple or complex. However, the exact distinction between these groups can be ambiguous. The term complex carbohydrate was first used in the U.S. Senate Select Committee on Nutrition and Human Needs publication Dietary Goals for the United States (1977) where it was intended to distinguish sugars from other carbohydrates (which were perceived to be nutritionally superior). However, the report put "fruit, vegetables and whole-grains" in the complex carbohydrate column, despite the fact that these may contain sugars as well as polysaccharides. This confusion persists as today some nutritionists use the term complex carbohydrate to refer to any sort of digestible saccharide present in a whole food, where fiber, vitamins and minerals are also found (as opposed to processed carbohydrates, which provide energy but few other nutrients). The standard usage, however, is to classify carbohydrates chemically: simple if they are sugars (monosaccharides and disaccharides) and complex if they are polysaccharides (or oligosaccharides).
In any case, the simple vs. complex chemical distinction has little value for determining the nutritional quality of carbohydrates. Some simple carbohydrates (e.g. fructose) raise blood glucose rapidly, while some complex carbohydrates (starches), raise blood sugar slowly. The speed of digestion is determined by a variety of factors including which other nutrients are consumed with the carbohydrate, how the food is prepared, individual differences in metabolism, and the chemistry of the carbohydrate. Carbohydrates are sometimes divided into "available carbohydrates", which are absorbed in the small intestine and "unavailable carbohydrates", which pass to the large intestine, where they are subject to fermentation by the gastrointestinal microbiota.
The USDA's Dietary Guidelines for Americans 2010 call for moderate- to high-carbohydrate consumption from a balanced diet that includes six one-ounce servings of grain foods each day, at least half from whole grain sources and the rest are from enriched.
The glycemic index (GI) and glycemic load concepts have been developed to characterize food behavior during human digestion. They rank carbohydrate-rich foods based on the rapidity and magnitude of their effect on blood glucose levels. Glycemic index is a measure of how quickly food glucose is absorbed, while glycemic load is a measure of the total absorbable glucose in foods. The insulin index is a similar, more recent classification method that ranks foods based on their effects on blood insulin levels, which are caused by glucose (or starch) and some amino acids in food.
Low-carbohydrate diets may miss the health advantages – such as increased intake of dietary fiber – afforded by high-quality carbohydrates found in legumes and pulses, whole grains, fruits, and vegetables. A "meta-analysis, of moderate quality," included as adverse effects of the diet halitosis, headache and constipation.
Carbohydrate-restricted diets can be as effective as low-fat diets in helping achieve weight loss over the short term when overall calorie intake is reduced. An Endocrine Society scientific statement said that "when calorie intake is held constant [...] body-fat accumulation does not appear to be affected by even very pronounced changes in the amount of fat vs carbohydrate in the diet." In the long term, effective weight loss or maintenance depends on calorie restriction, not the ratio of macronutrients in a diet. The reasoning of diet advocates that carbohydrates cause undue fat accumulation by increasing blood insulin levels, and that low-carbohydrate diets have a "metabolic advantage", is not supported by clinical evidence. Further, it is not clear how low-carbohydrate dieting affects cardiovascular health, although two reviews showed that carbohydrate restriction may improve lipid markers of cardiovascular disease risk.
Carbohydrate-restricted diets are no more effective than a conventional healthy diet in preventing the onset of type 2 diabetes, but for people with type 2 diabetes, they are a viable option for losing weight or helping with glycemic control. There is limited evidence to support routine use of low-carbohydrate dieting in managing type 1 diabetes. The American Diabetes Association recommends that people with diabetes should adopt a generally healthy diet, rather than a diet focused on carbohydrate or other macronutrients.
An extreme form of low-carbohydrate diet – the ketogenic diet – is established as a medical diet for treating epilepsy. Through celebrity endorsement during the early 21st century, it became a fad diet as a means of weight loss, but with risks of undesirable side effects, such as low energy levels and increased hunger, insomnia, nausea, and gastrointestinal discomfort. The British Dietetic Association named it one of the "top 5 worst celeb diets to avoid in 2018".
Most dietary carbohydrates contain glucose, either as their only building block (as in the polysaccharides starch and glycogen), or together with another monosaccharide (as in the hetero-polysaccharides sucrose and lactose). Unbound glucose is one of the main ingredients of honey. Glucose is extremely abundant and has been isolated from a variety of natural sources across the world, including male cones of the coniferous tree Wollemia nobilis in Rome, the roots of Ilex asprella plants in China, and straws from rice in California.
^A The carbohydrate value is calculated in the USDA database and does not always correspond to the sum of the sugars, the starch, and the "dietary fiber".
Carbohydrate metabolism is the series of biochemical processes responsible for the formation, breakdown and interconversion of carbohydrates in living organisms.
The most important carbohydrate is glucose, a simple sugar (monosaccharide) that is metabolized by nearly all known organisms. Glucose and other carbohydrates are part of a wide variety of metabolic pathways across species: plants synthesize carbohydrates from carbon dioxide and water by photosynthesis storing the absorbed energy internally, often in the form of starch or lipids. Plant components are consumed by animals and fungi, and used as fuel for cellular respiration. Oxidation of one gram of carbohydrate yields approximately 16 kJ (4 kcal) of energy, while the oxidation of one gram of lipids yields about 38 kJ (9 kcal). The human body stores between 300 and 500 g of carbohydrates depending on body weight, with the skeletal muscle contributing to a large portion of the storage. Energy obtained from metabolism (e.g., oxidation of glucose) is usually stored temporarily within cells in the form of ATP. Organisms capable of anaerobic and aerobic respiration metabolize glucose and oxygen (aerobic) to release energy, with carbon dioxide and water as byproducts.
Catabolism is the metabolic reaction which cells undergo to break down larger molecules, extracting energy. There are two major metabolic pathways of monosaccharide catabolism: glycolysis and the citric acid cycle.
In glycolysis, oligo- and polysaccharides are cleaved first to smaller monosaccharides by enzymes called glycoside hydrolases. The monosaccharide units can then enter into monosaccharide catabolism. A 2 ATP investment is required in the early steps of glycolysis to phosphorylate Glucose to Glucose 6-Phosphate (G6P) and Fructose 6-Phosphate (F6P) to Fructose 1,6-biphosphate (FBP), thereby pushing the reaction forward irreversibly. In some cases, as with humans, not all carbohydrate types are usable as the digestive and metabolic enzymes necessary are not present.
Carbohydrate chemistry is a large and economically important branch of organic chemistry. Some of the main organic reactions that involve carbohydrates are: | [

Plant components are consumed by animals and fungi, and used as fuel for cellular respiration. Oxidation of one gram of carbohydrate yields approximately 16 kJ (4 kcal) of energy, while the oxidation of one gram of lipids yields about 38 kJ (9 kcal). The human body stores between 300 and 500 g of carbohydrates depending on body weight, with the skeletal muscle contributing to a large portion of the storage. Energy obtained from metabolism (e.g., oxidation of glucose) is usually stored temporarily within cells in the form of ATP.

] | A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 and thus with the empirical formula Cm(H2O)n, which does not mean the H has covalent bonds with O. However, not all carbohydrates conform to this precise stoichiometric definition, nor are all chemicals that do conform to this definition automatically classified as carbohydrates. The term is most common in biochemistry, where it is a synonym of saccharide, a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest carbohydrates, are commonly referred to as sugars. While the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix -ose, which was originally taken from the word glucose, and is used for almost all sugars, e.g. fructose, sucrose, ribose, lactose, etc. Carbohydrates perform numerous roles in living organisms. Polysaccharides serve as an energy store and as structural components. The 5-carbon monosaccharide ribose is an important component of coenzymes and the backbone of the genetic molecule known as RNA. The related deoxyribose is a component of DNA. Saccharides and their derivatives include many other important biomolecules that play key roles in the immune system, fertilization, preventing pathogenesis, blood clotting, and development. Carbohydrates are central to nutrition and are found in a wide variety of natural and processed foods. Starch is a polysaccharide and is abundant in cereals, potatoes, and processed food based on cereal flour, such as bread, pizza or pasta. Sugars appear in human diet mainly as table sugar, lactose, glucose and fructose, both of which occur naturally in honey, many fruits, and some vegetables. Table sugar, milk, or honey are often added to drinks and many prepared foods such as jam, biscuits and cakes. Cellulose, a polysaccharide found in the cell walls of all plants, is one of the main components of insoluble dietary fiber. Although it is not digestible by humans, cellulose and insoluble dietary fiber generally help maintain a healthy digestive system by facilitating bowel movements. Other polysaccharides contained in dietary fiber include resistant starch and inulin, which feed some bacteria in the microbiota of the large intestine, and are metabolized by these bacteria to yield short-chain fatty acids. | 2001-09-15T17:50:14Z | 2023-11-25T21:33:42Z | [

5,933 | CSS Virginia | CSS Virginia was the first steam-powered ironclad warship built by the Confederate States Navy during the first year of the American Civil War; she was constructed as a casemate ironclad using the razéed (cut down) original lower hull and engines of the scuttled steam frigate USS Merrimack. Virginia was one of the participants in the Battle of Hampton Roads, opposing the Union's USS Monitor in March 1862. The battle is chiefly significant in naval history as the first battle between ironclads.
When the Commonwealth of Virginia seceded from the Union in 1861, one of the important US military bases threatened was Gosport Navy Yard (now Norfolk Naval Shipyard) in Portsmouth, Virginia. Accordingly, orders were sent to destroy the base rather than allow it to fall into Confederate hands. On the afternoon of 17 April, the day Virginia seceded, Engineer in Chief B. F. Isherwood managed to get the frigate's engines lit. However, the previous night secessionists had sunk light boats between Craney Island and Sewell's Point, blocking the channel. On 20 April, before evacuating the Navy Yard, the U. S. Navy burned Merrimack to the waterline and sank her to preclude capture. When the Confederate government took possession of the fully provisioned yard, the base's new commander, Flag Officer French Forrest, contracted on May 18 to salvage the wreck of the frigate. This was completed by May 30, and she was towed into the shipyard's only dry dock (today known as Drydock Number One), where the burned structures were removed.
The wreck was surveyed and her lower hull and machinery were discovered to be undamaged. Stephen Mallory, Secretary of the Navy decided to convert Merrimack into an ironclad, since she was the only large ship with intact engines available in the Chesapeake Bay area. Preliminary sketch designs were submitted by Lieutenants John Mercer Brooke and John L. Porter, each of whom envisaged the ship as a casemate ironclad. Brooke's general design showed the bow and stern portions submerged, and his design was the one finally selected. The detailed design work would be completed by Porter, who was a trained naval constructor. Porter had overall responsibility for the conversion, but Brooke was responsible for her iron plate and heavy ordnance, while William P. Williamson, Chief Engineer of the Navy, was responsible for the ship's machinery.
The hull's burned timbers were cut down past the vessel's original waterline, leaving just enough clearance to accommodate her large, twin-bladed screw propeller. A new fantail and armored casemate were built atop a new main deck, and a v-shaped breakwater (bulwark) was added to her bow, which attached to the armored casemate. This forward and aft main deck and fantail were designed to stay submerged and were covered in 4-inch-thick (10 cm) iron plate, built up in two layers. The casemate was built of 24 inches (61 cm) of oak and pine in several layers, topped with two 2-inch (51 mm) layers of iron plating oriented perpendicular to each other, and angled at 36 degrees from horizontal to deflect fired enemy shells.
From reports in Northern newspapers, Virginia's designers were aware of the Union plans to build an ironclad and assumed their similar ordnance would be unable to do much serious damage to such a ship. It was decided to equip their ironclad with a ram, an anachronism on a 19th century warship. Merrimack's steam engines, now part of Virginia, were in poor working order; they had been slated for replacement when the decision was made to abandon the Norfolk naval yard. The salty Elizabeth River water and the addition of tons of iron armor and pig iron ballast, added to the hull's unused spaces for needed stability after her initial refloat, and to submerge her unarmored lower levels, only added to her engines' propulsion issues. As completed, Virginia had a turning radius of about 1 mile (1.6 km) and required 45 minutes to complete a full circle, which would later prove to be a major handicap in battle with the far more nimble Monitor.
The ironclad's casemate had 14 gun ports, three each in the bow and stern, one firing directly along the ship's centerline, the two others angled at 45° from the center line; these six bow and stern gun ports had exterior iron shutters installed to protect their cannon. There were four gun ports on each broadside; their protective iron shutters remained uninstalled during both days of the Battle of Hampton Roads. Virginia's battery consisted of four muzzle-loading single-banded Brooke rifles and six smoothbore 9-inch (229 mm) Dahlgren guns salvaged from the old Merrimack. Two of the rifles, the bow and stern pivot guns, were 7-inch (178 mm) caliber and weighed 14,500 pounds (6,600 kg) each. They fired a 104-pound (47 kg) shell. The other two were 6.4-inch (163 mm) cannon of about 9,100 pounds (4,100 kg), one on each broadside. The 9-inch Dahlgrens were mounted three to a side; each weighed approximately 9,200 pounds (4,200 kg) and could fire a 72.5-pound (32.9 kg) shell up to a range of 3,357 yards (3,070 m) (or 1.9 miles) at an elevation of 15°. Both amidship Dahlgrens nearest the boiler furnaces were fitted-out to fire heated shot. On her upper casemate deck were positioned two anti-boarding/personnel 12-pounder Howitzers.
Virginia's commanding officer, Flag Officer Franklin Buchanan, arrived to take command only a few days before her first sortie; the ironclad was placed in commission and equipped by her executive officer, Lieutenant Catesby ap Roger Jones.
The Battle of Hampton Roads began on March 8, 1862, when Virginia engaged the blockading Union fleet. Despite an all-out effort to complete her, the new ironclad still had workmen on board when she sailed into Hampton Roads with her flotilla of five CSN support ships: Raleigh (serving as Virginia's tender) and Beaufort, Patrick Henry, Jamestown, and Teaser.
The first Union ship to be engaged by Virginia was the all-wood, sail-powered USS Cumberland, which was first crippled during a furious cannon exchange, and then rammed in her forward starboard bow by Virginia. As Cumberland began to sink, the port side half of Virginia's iron ram was broken off, causing a bow leak in the ironclad. Seeing what had happened to Cumberland, the captain of USS Congress ordered his frigate into shallower water, where she soon grounded. Congress and Virginia traded cannon fire for an hour, after which the badly-damaged Congress finally surrendered. While the surviving crewmen of Congress were being ferried off the ship, a Union battery on the north shore opened fire on Virginia. Outraged at such a breach of war protocol, in retaliation Virginia's now angry captain, Commodore Franklin Buchanan, gave the order to open fire with hot-shot on the surrendered Congress as he rushed to Virginia's exposed upper casemate deck, where he was injured by enemy rifle fire. Congress, now set ablaze by the retaliatory shelling, burned for many hours into the night, a symbol of Confederate naval power and a costly wake-up call for the all-wood Union blockading squadron.
Virginia did not emerge from the battle unscathed, however. Her hanging port side anchor was lost after ramming Cumberland; the bow was leaking from the loss of the ram's port side half; shot from Cumberland, Congress, and the shore-based Union batteries had riddled her smokestack, reducing her boilers' draft and already slow speed; two of her broadside cannon (without shutters) were put out of commission by shell hits; a number of her armor plates had been loosened; both of Virginia's 22-foot (6.7 m) cutters had been shot away, as had both 12 pounder anti-boarding/anti-personnel howitzers, most of the deck stanchions, railings, and both flagstaffs. Even so, the now-injured Buchanan ordered an attack on USS Minnesota, which had run aground on a sandbar trying to escape Virginia. However, because of the ironclad's 22-foot (6.7 m) draft (fully loaded), she was unable to get close enough to do any significant damage. It being late in the day, Virginia retired from the conflict with the expectation of returning the next day and completing the destruction of the remaining Union blockaders.
Later that night, USS Monitor arrived at Union-held Fort Monroe. She had been rushed to Hampton Roads, still not quite complete, all the way from the Brooklyn Navy Yard, in hopes of defending the force of wooden ships and preventing "the rebel monster" from further threatening the Union's blockading fleet and nearby cities, like Washington, D.C. While under tow, she nearly foundered twice during heavy storms on her voyage south, arriving in Hampton Roads by the bright firelight from the still-burning triumph of Virginia's first day of handiwork.
The next day, on March 9, 1862, the world's first battle between ironclads took place. The smaller, nimbler, and faster Monitor was able to outmaneuver the larger, slower Virginia, but neither ship proved able to do any severe damage to the other, despite numerous shell hits by both combatants, many fired at virtually point-blank range. Monitor had a much lower freeboard and only its single, rotating, two-cannon gun turret and forward pilothouse sitting above her deck, and thus was much harder to hit with Virginia's heavy cannon. After hours of shell exchanges, Monitor finally retreated into shallower water after a direct shell hit to her armored pilothouse forced her away from the conflict to assess the damage. The captain of the Monitor, Lieutenant John L. Worden, had taken a direct gunpowder explosion to his face and eyes, blinding him, while looking through the pilothouse's narrow, horizontal viewing slits. Monitor remained in the shallows, but as it was late in the day, Virginia steamed for her home port, the battle ending without a clear victor. The captain of Virginia that day, Lieutenant Catesby ap Roger Jones, received advice from his pilots to depart over the sandbar toward Norfolk until the next day. Lieutenant Jones wanted to continue the fight, but the pilots emphasized that the Virginia had "nearly three miles to run to the bar" and that she could not remain and "take the ground on a falling tide." To prevent running aground, Lieutenant Jones reluctantly moved the ironclad back toward port. Virginia retired to the Gosport Naval Yard at Portsmouth, Virginia, and remained in drydock for repairs until April 4, 1862.
In the following month, the crew of Virginia were unsuccessful in their attempts to break the Union blockade. The blockade had been bolstered by the hastily ram-fitted paddle steamer USS Vanderbilt, and SS Illinois as well as the SS Arago and USS Minnesota, which had been repaired. Virginia made several sorties back over to Hampton Roads hoping to draw Monitor into battle. Monitor, however, was under strict orders not to re-engage; the two combatants would never battle again.
On April 11, the Confederate Navy sent Lieutenant Joseph Nicholson Barney, in command of the paddle side-wheeler CSS Jamestown, along with Virginia and five other ships in full view of the Union squadron, enticing them to fight. When it became clear that Union Navy ships were unwilling to fight, the CS Navy squadron moved in and captured three merchant ships, the brigs Marcus and Sabout and the schooner Catherine T. Dix. Their ensigns were then hoisted "Union-side down" to further taunt the Union Navy into a fight, as they were towed back to Norfolk, with the help of CSS Raleigh.
By late April, the new Union ironclads USRC E. A. Stevens and USS Galena had also joined the blockade. On May 8, 1862, Virginia and the James River Squadron ventured out when the Union ships began shelling the Confederate fortifications near Norfolk, but the Union ships retired under the shore batteries on the north side of the James River and on Rip Raps island.
On May 10, 1862, advancing Union troops occupied Norfolk. Since Virginia was now a steam-powered heavy battery and no longer an ocean-going cruiser, her pilots judged her not seaworthy enough to enter the Atlantic, even if she were able to pass the Union blockade. Virginia was also unable to retreat further up the James River due to her deep 22-foot (6.7 m) draft (fully loaded). In an attempt to reduce it, supplies and coal were dumped overboard, even though this exposed the ironclad's unarmored lower hull; this was still not enough to make a difference. Without a home port and no place to go, Virginia's new captain, flag officer Josiah Tattnall III, reluctantly ordered her destruction in order to keep the ironclad from being captured. This task fell to Lieutenant Jones, the last man to leave Virginia after her cannons had been safely removed and carried to the Confederate Marine Corps base and fortifications at Drewry's Bluff. Early on the morning of May 11, 1862, off Craney Island, fire and powder trails reached the ironclad's magazine and she was destroyed by a great explosion. What remained of the ship settled to the bottom of the harbor. Only a few remnants of Virginia have been recovered for preservation in museums; reports from the era indicate that her wreck was heavily salvaged following the war.
Monitor was lost on December 31 of the same year, when the vessel was swamped by high waves in a violent storm while under tow by the tug USS Rhode Island off Cape Hatteras, North Carolina. Sixteen of her 62-member crew were either lost overboard or went down with the ironclad, while many others were saved by lifeboats sent from Rhode Island. Subsequently, in August 1973, the wreckage was located on the floor of the Atlantic Ocean about 16 nautical miles (30 kilometres; 18 miles) southeast of Cape Hatteras. Her upside-down turret was raised from beneath her deep, capsized wreck years later with the remains of two of her crew still aboard; they were later buried with full military honors on March 8, 2013, at Arlington National Cemetery in Washington, D.C.
Although the Confederacy renamed the ship, she is still frequently referred to by her Union name. When she was first commissioned into the United States Navy in 1856, her name was Merrimack, with the K; the name was derived from the Merrimack River near where she was built. She was the second ship of the U. S. Navy to be named for the Merrimack River, which is formed by the confluence of the Pemigewasset and Winnipesaukee rivers at Franklin, New Hampshire. The Merrimack flows south across New Hampshire, then eastward across northeastern Massachusetts before finally emptying in the Atlantic at Newburyport, Massachusetts.
After raising, restoring, and outfitting as an ironclad warship, the Confederacy bestowed on her the name Virginia. Nonetheless, the Union continued to refer to the Confederate ironclad by either its original name, Merrimack, or by the nickname "The Rebel Monster". In the aftermath of the Battle of Hampton Roads, the names Virginia and Merrimack were used interchangeably by both sides, as attested to by various newspapers and correspondence of the day. Navy reports and pre-1900 historians frequently misspelled the name as "Merrimac", which was actually an unrelated ship, hence "the Battle of the Monitor and the Merrimac". Both spellings are still in use in the Hampton Roads area.

The smaller, nimbler, and faster Monitor was able to outmaneuver the larger, slower Virginia, but neither ship proved able to do any severe damage to the other, despite numerous shell hits by both combatants, many fired at virtually point-blank range. Monitor had a much lower freeboard and only its single, rotating, two-cannon gun turret and forward pilothouse sitting above her deck, and thus was much harder to hit with Virginia's heavy cannon. After hours of shell exchanges, Monitor finally retreated into shallower water after a direct shell hit to her armored pilothouse forced her away from the conflict to assess the damage. The captain of the Monitor, Lieutenant John L. Worden, had taken a direct gunpowder explosion to his face and eyes, blinding him, while looking through the pilothouse's narrow, horizontal viewing slits. Monitor remained in the shallows, but as it was late in the day, Virginia steamed for her home port, the battle ending without a clear victor. The captain of Virginia that day, Lieutenant Catesby ap Roger Jones, received advice from his pilots to depart over the sandbar toward Norfolk until the next day. Lieutenant Jones wanted to continue the fight, but the pilots emphasized that the Virginia had \"nearly three miles to run to the bar\" and that she could not remain and \"take the ground on a falling tide.\" To prevent running aground, Lieutenant Jones reluctantly moved the ironclad back toward port. Virginia retired to the Gosport Naval Yard at Portsmouth, Virginia, and remained in drydock for repairs until April 4, 1862.",

Since Virginia was now a steam-powered heavy battery and no longer an ocean-going cruiser, her pilots judged her not seaworthy enough to enter the Atlantic, even if she were able to pass the Union blockade. Virginia was also unable to retreat further up the James River due to her deep 22-foot (6.7 m) draft (fully loaded). In an attempt to reduce it, supplies and coal were dumped overboard, even though this exposed the ironclad's unarmored lower hull; this was still not enough to make a difference. Without a home port and no place to go, Virginia's new captain, flag officer Josiah Tattnall III, reluctantly ordered her destruction in order to keep the ironclad from being captured. This task fell to Lieutenant Jones, the last man to leave Virginia after her cannons had been safely removed and carried to the Confederate Marine Corps base and fortifications at Drewry's Bluff. Early on the morning of May 11, 1862, off Craney Island, fire and powder trails reached the ironclad's magazine and she was destroyed by a great explosion. What remained of the ship settled to the bottom of the harbor. Only a few remnants of Virginia have been recovered for preservation in museums; reports from the era indicate that her wreck was heavily salvaged following the war.",

] | CSS Virginia was the first steam-powered ironclad warship built by the Confederate States Navy during the first year of the American Civil War; she was constructed as a casemate ironclad using the razéed original lower hull and engines of the scuttled steam frigate USS Merrimack. Virginia was one of the participants in the Battle of Hampton Roads, opposing the Union's USS Monitor in March 1862. The battle is chiefly significant in naval history as the first battle between ironclads. | 2023-04-10T02:54:23Z | [

5,935 | The Church of Jesus Christ of Latter-day Saints | The Church of Jesus Christ of Latter-day Saints, informally known as the LDS Church or Mormon Church, is a restorationist, nontrinitarian Christian denomination that is the largest denomination in the Latter Day Saint movement. The church is headquartered in the United States in Salt Lake City, Utah and has established congregations and built temples worldwide. According to the church, it has over 17 million members and over 72,000 full-time volunteer missionaries. The church was the fourth-largest Christian denomination in the United States as of 2012, and reported over 6.8 million US members as of 2022.
The church was founded as the Church of Christ in western New York, in 1830 by Joseph Smith during the Second Great Awakening. Under Smith's leadership, the church's headquarters moved successively to Ohio, Missouri, and Illinois. After Smith's 1844 death and a resultant succession crisis, the majority of his followers sided with Brigham Young, who led the church to its current headquarters in Salt Lake City. Young and his successors continued the church's growth, first throughout the Intermountain West, and more recently as a national and international organization.
Church theology includes the Christian doctrine of salvation through Jesus Christ, and his substitutionary atonement on behalf of mankind. The church has an open canon of four scriptural texts: the Bible, the Book of Mormon, the Doctrine and Covenants (D&C), and the Pearl of Great Price. Other than the Bible, the majority of the church canon consists of material the church's members believe to have been revealed by God to Joseph Smith, including commentary and exegesis about the Bible, texts described as lost parts of the Bible, and other works believed to be written by ancient prophets, including the Book of Mormon. Because of doctrinal differences, many Christian groups consider the church to be distinct and separate from mainstream Christianity.
Members of the church, known as Latter-day Saints or Mormons, believe that the church president is a modern-day "prophet, seer, and revelator" and that Jesus Christ, under the direction of God the Father, leads the church by revealing his will and delegating his priesthood keys to its president. The president heads a hierarchical structure descending from areas to stakes and wards. The church has a volunteer clergy at the local and regional levels; wards are led by bishops, who are drawn from the membership of the wards themselves. Male members may be ordained to the priesthood, provided they are living the standards of the church. Women are not ordained to the priesthood, but occupy leadership roles in some church organizations.
Both men and women may serve as missionaries. The church maintains a large missionary program that proselytizes and conducts humanitarian services worldwide. The church also funds and participates in humanitarian projects independent of its missionary efforts. Faithful members adhere to church laws of sexual purity, health, fasting, and Sabbath observance, and contribute ten percent of their income to the church in tithing. The church teaches sacred ordinances through which adherents make covenants with God, including baptism, confirmation, the sacrament, priesthood ordination, endowment and celestial marriage.
The church has been criticized throughout its history. Modern criticisms include disputes over the church's historical claims, treatment of minorities, and finances. The church's practice of polygamy (plural marriage) was controversial until it was curtailed in 1890 and officially rescinded in 1904.
The history of the church can be divided into three broad time periods: (1) the early history during the lifetime of Joseph Smith, which is in common with all churches associated with the Latter Day Saint movement, (2) a pioneer era under the leadership of Brigham Young and his 19th-century successors, and (3) a modern era beginning around the turn of the 20th century as Utah achieved statehood.
Joseph Smith formally organized the church as the Church of Christ, on April 6, 1830, in western New York; the church's name was later changed to the Church of Jesus Christ of Latter Day Saints. Initial converts were drawn to the church in part because of the newly published Book of Mormon, a self-described chronicle of indigenous American prophets that Smith said he had translated from golden plates.
Smith intended to establish the New Jerusalem in North America, called Zion. In 1831, the church moved to Kirtland, Ohio, and began establishing an outpost in Jackson County, Missouri, where Smith planned to eventually move the church headquarters. However, in 1833, Missouri settlers violently expelled the Latter Day Saints from Jackson County. The church attempted to recover the land through a paramilitary expedition, but did not succeed. Nevertheless, the church flourished in Kirtland as Smith published new revelations and the church built the Kirtland Temple,}} culminating in a dedication of the building similar to the day of Pentecost. The Kirtland era ended in 1838, after a financial scandal rocked the church and caused widespread defections. Smith regrouped with the remaining church in Far West, Missouri, but tensions soon escalated into violent conflicts with the old Missouri settlers. Believing the Latter Day Saints to be in insurrection, the Missouri governor ordered that they be "exterminated or driven from the State". In 1839, the Saints converted a swampland on the banks of the Mississippi River into Nauvoo, Illinois, which became the church's new headquarters.
Nauvoo grew rapidly as missionaries sent to Europe and elsewhere gained new converts who then flooded into Nauvoo. Meanwhile, Smith introduced polygamy to his closest associates. He also established ceremonies, which he stated the Lord had revealed to him, to allow righteous people to become gods in the afterlife, and a secular institution to govern the Millennial kingdom. He also introduced the church to a full accounting of his First Vision, in which two heavenly "personages" appeared to him at age 14. This vision would come to be regarded by the LDS Church as the most important event in human history since the resurrection of Jesus.
On June 27, 1844, Smith and his brother, Hyrum, were killed by a mob in Carthage, Illinois, while being held on charges of treason. Because Hyrum was Joseph's designated successor, their deaths caused a succession crisis, and Brigham Young assumed leadership over a majority of the church's membership. Young had been a close associate of Smith's and was the president of the Quorum of the Twelve Apostles in Smith's church.
Other splinter groups followed other leaders around this time. These groups have no affiliation with the LDS Church, however they share a common heritage in their early church history. Collectively, they are called the Latter Day Saint movement. The largest of these smaller groups is the Community of Christ, based in Independence, Missouri, followed by the Church of Jesus Christ, based in Monongahela, Pennsylvania. Like the LDS Church, these faiths believe in Joseph Smith as a prophet and founder of their religion. They also accept the Book of Mormon, and most accept at least some version of the Doctrine and Covenants. However, they tend to disagree to varying degrees with the LDS Church concerning doctrine and church leadership.
For two years after Smith's death, conflicts escalated between Mormons and other Illinois residents. Brigham Young led his followers, later called the Mormon pioneers, westward to Nebraska and then in 1847 on to what later became the Utah Territory, which at the time had been part of the indigenous lands of the Ute, Goshute, and Shoshone nations, and claimed by Mexico until 1848. Around 80,000 settlers arrived between 1847 and 1869, who then branched out and colonized a large region now known as the Mormon Corridor.
Young incorporated the LDS Church as a legal entity, and initially governed both the church and the state as a theocratic leader. He also publicized the practice of plural marriage in 1852. Modern research suggests that around 20 percent of Mormon families may have participated in the practice.
By 1857, tensions had again escalated between Mormons and other Americans, largely as a result of accusations involving polygamy and the theocratic rule of the Utah Territory by Young. The Utah Mormon War ensued from 1857 to 1858, which resulted in the relatively peaceful invasion of Utah by the United States Army. The most notable instance of violence during this conflict was the Mountain Meadows massacre, in which leaders of a local Mormon militia ordered the massacre of a civilian emigrant party who was traveling through Utah during the escalating military tensions. After the massacre was discovered, the church became the target of significant media criticism for it.
After the Army withdrew, Young agreed to step down from power and be replaced by a non-Mormon territorial governor, Alfred Cumming. Nevertheless, the LDS Church still wielded significant political power in the Utah Territory. Coterminously, tensions between Mormon settlers and indigenous tribes continued to escalate as settlers began colonizing a growing area of tribal lands. While Mormons and indigenous peoples made attempts at peaceful coexistence, skirmishes ensued from about 1849 to 1873 culminating in the armed conflicts of Walkara's War, the Bear River Massacre, and the Black Hawk War.
After Young's death in 1877, he was followed by other church presidents, who resisted efforts by the United States Congress to outlaw Mormon polygamous marriages. In 1878, the United States Supreme Court, in Reynolds v. United States, decreed that "religious duty" to engage in plural marriage was not a valid defense to prosecutions for violating state laws against polygamy. Conflict between Mormons and the U.S. government escalated to the point that, in 1890, Congress disincorporated the LDS Church and seized most of its assets. Soon thereafter, church president Wilford Woodruff issued a manifesto that officially suspended the performance of new polygamous marriages in the United States. Relations with the United States markedly improved after 1890, such that Utah was admitted as a U.S. state in 1896. Relations further improved after 1904, when church president Joseph F. Smith again disavowed polygamy before the United States Congress and issued a "Second Manifesto", calling for all plural marriages in the church to cease. Eventually, the church adopted a policy of excommunicating its members found practicing polygamy. Some fundamentalist groups with relatively small memberships have broken off and continue to practice polygamy, but the Church distances itself from them.
During the 20th century, the church grew substantially and became an international organization. In 2000, the church reported over 60,000 missionaries and global church membership stood at just over 11 million. Nominal worldwide membership surpassed 16 million in 2018. Slightly under half of church membership lives within the United States.
The church has become a strong proponent of the nuclear family and at times played a prominent role in political matters, including opposition to MX Peacekeeper missile bases in Utah and Nevada, the Equal Rights Amendment, legalized gambling, same-sex marriage, and physician-assisted death.
A number of official changes have taken place to the organization during the modern era. In 1978, the church reversed its previous policy of excluding black men of African descent from the priesthood, which had been in place since 1852; members of all races can now be ordained to the priesthood. Also, since the early 1900s, the church has instituted a Priesthood Correlation Program to centralize church operations and bring them under a hierarchy of priesthood leaders. During the Great Depression, the church also began operating a church welfare system, and it has conducted humanitarian efforts in cooperation with other religious organizations such as Catholic Relief Services, as well as secular organizations like Care International.
During the second half of the 20th century and beginnings of the 21st, the church has responded to various challenges to its doctrine and authority. Challenges have included rising secularization, challenges to the correctness of the translation of the Book of Abraham, and primary documents forged by Mark Hofmann purporting to contradict important aspects of official early church history. The church's positions regarding homosexuality, women, and black people have all been publicly criticized during this timeframe.
For over 100 years, the church was a major sponsor of Scouting programs for boys, particularly in the United States. The LDS Church was the largest chartered organization in the Boy Scouts of America, having joined the Boy Scouts of America as its first charter organization in 1913. In 2020, the church ended its relationship with the BSA and began an alternate, religion-centered youth program, which replaced all other youth programs. Prior to leaving the Scouting program, LDS Scouts made up nearly 20 percent of all enrolled Boy Scouts, more than any other church.
LDS Church theology includes the belief in a Godhead composed of God the Father, his son, Jesus Christ, and the Holy Ghost as three separate persons who share a unity of purpose or will; however, they are viewed as three distinct beings. This is in contrast with the predominant Christian view, which holds that God is a Trinity of three distinct persons in one essence. The Latter-day Saint conception of the Godhead is similar to what contemporary Christian theologians call social trinitarianism. The church also believes that God the Father and his son, Jesus Christ, are separate beings with bodies of flesh and bone, while the Holy Ghost lacks such a physical body.
According to statements by church leaders, God sits at the head of the human family and is married to a Heavenly Mother, who is the mother of human spirits. However, church leaders have also categorically discouraged prayers to her and counseled against speculation regarding her.
Church members believe in Jesus Christ as the literal Son of God and Messiah, his crucifixion as a conclusion of a sin offering, and his subsequent resurrection. However, Latter-day Saints reject the ecumenical creeds and the definition of the Trinity. Jesus is also seen as the elder brother of all who live in this world. The church teaches that Jesus performed a substitutionary atonement; in contrast with other Christian denominations, the church teaches this atonement began in the garden of Gethsemane and continued to his crucifixion (rather than the orthodox belief that the crucifixion alone was the physical atonement). The church also teaches that Christ appeared to other peoples after his death, including spirits of the dead in the spirit world, and indigenous Americans.
The church also teaches that Jesus is the true founder and leader of the church itself. The physical establishment of the church by Smith in 1830 is seen as simply the reestablishment of the same primitive church that existed under Jesus and his Apostles. Similarly, the church teaches that Jesus leads the church presently through its apostles and prophets, especially its current president.
The LDS Church shares various teachings with other branches of Christianity. These include a belief in the Bible, the divinity of Jesus, and his atonement and resurrection. LDS theology also includes belief in the doctrine of salvation through Jesus alone, restorationism, millennialism, continuationism, conditional substitutionary atonement or penal substitution, and a form of apostolic succession.
Nevertheless, the LDS Church differs from other churches within contemporary Christianity in other ways. Differences between the LDS Church and most of traditional Christianity include disagreement about the nature of God, belief in a theory of human salvation that includes three heavens, a doctrine of exaltation which includes the ability of humans to become gods and goddesses in the afterlife, a belief in continuing revelation and an open scriptural canon, and unique ceremonies performed privately in temples, such as the endowment and sealing ceremonies. A number of major Christian denominations view the LDS Church as standing apart from creedal Christianity. However, church members self-identify as Christians.
The faith itself views other modern Christian faiths as having departed from true Christianity by way of a general apostasy and maintains that it is a restoration of 1st-century Christianity and the only true and authorized Christian church. Church leaders assert it is the only true church and that other churches do not have the authority to act in Jesus' name.
The church's cosmology and plan of salvation include the doctrines of a pre-existence, an earthly mortal existence, three degrees of heaven and exaltation.
According to these doctrines, every human spirit is a spiritual child of a Heavenly Father and each has the potential to continue to learn, grow, and progress in the eternities, eventually achieving eternal life, which is to become one with God in the same way that Jesus Christ is one with the Father, thus allowing the children of God to become divine beings—that is, gods—themselves. This view on the doctrine of theosis is also referred to as becoming a "joint-heir with Christ". The process by which this is accomplished is called exaltation, a doctrine which includes the reunification of the mortal family after the resurrection and the ability to have spirit children in the afterlife and inherit a portion of God's kingdom. To obtain this state of godhood, the church teaches that one must have faith in Jesus Christ, repent of his or her sins, strive to keep the commandments faithfully, and participate in ordinances.
According to LDS Church theology, men and women may be sealed to one another so that their marital bond continues into the eternities. Children may also be sealed to their biological or adoptive parents to form permanent familial bonds, thus allowing all immediate and extended family relations to endure past death. The most significant LDS ordinances may be performed via proxy in behalf of those who have died, such as baptism for the dead. The church teaches that all will have the opportunity to hear and accept or reject the gospel of Jesus Christ, either in this life or the next.
Within church cosmology, the fall of Adam and Eve is seen positively. The church teaches that it was essential to allow humankind to experience separation from God, to exercise full agency in making decisions for their own happiness.
The LDS Church teaches that, subsequent to the death of Jesus and his original apostles, his church, along with the authority to act in Jesus Christ's name and the church's attendant spiritual gifts, were lost, due to a combination of external persecutions and internal heresies. The restoration—as represented by the church began by Joseph Smith—refers to a return of the authentic priesthood power, spiritual gifts, ordinances, living prophets and revelation of the primitive Church of Christ. This restoration is associated with a number of events which are understood to have been necessary to re-establish the early Christian church found in the New Testament, and to prepare the earth for the Second Coming of Jesus. In particular, Latter-day Saints believe that angels appeared to Joseph Smith and a limited number of his associates, and bestowed various priesthood authorities on them.
The church is led by a president, who is considered a "prophet, seer, and revelator." Within the church, he is referred to as "the Prophet" or the "President of the Church." He is considered the only person who is authorized to receive revelation from God on behalf of the whole world or entire church. As such, the church teaches that he is essentially infallible when speaking on behalf of God—although the exact circumstances when his pronouncements should be considered authoritative are debated within the church. In any case, modern declarations with broad doctrinal implications are often issued by joint statement of the First Presidency; they may be joined by the Quorum of the Twelve Apostles as well. Church members believe Joseph Smith was the first modern-day prophet.
Normally, the Prophet and two other ordained apostles he chooses as counselors form the First Presidency, the presiding body of the church; twelve other apostles form the Quorum of the Twelve Apostles. When a president dies, his successor is chosen from the remaining apostles, and is invariably the longest-tenured of the group. Apostles are chosen by the church president after the death of an existing apostle. Following the death of church president Thomas S. Monson on January 2, 2018, senior apostle Russell M. Nelson was announced as president on January 16.
The church and its members consider marriage and family highly important, with emphasis placed on large, nuclear families. In 1995, the church's First Presidency and Quorum of the Twelve issued "The Family: A Proclamation to the World", which asserts the importance of a heterosexual, nuclear family. The proclamation defined marriage as a union between one man and one woman and stated that the family unit is "central to the Creator's plan for the eternal destiny of His children." The document further says that "gender is an essential characteristic of individual premortal, mortal, and eternal identity and purpose," that the father and mother have differing roles as "equal partners" (with the father presiding) in raising children, and that successful marriages and families, founded upon the teachings of Jesus Christ, can last eternally. The proclamation also promotes specific roles essential to maintaining the strength of the family unit—the roles of a husband and father as the family's breadwinner and spiritual leader and those of a wife and mother as a nurturing caregiver. Both parents are charged with the duties of childrearing. Senior church leaders have continued to emphasize conservative teachings on marriage and gender to the present time.
LDS Church members are encouraged to set aside one evening each week, typically Monday, to spend together in "Family Home Evening." Family Home Evenings typically consist of gathering as a family to study the faith's gospel principles, and other family activities. Daily family prayer is also encouraged.
The theology of the LDS Church consists of a combination of biblical doctrines with modern revelations and other commentary by LDS leaders, particularly Joseph Smith. The most authoritative sources of theology are the faith's canon of four religious texts, called the "standard works". Included in the standard works are the Bible, the Book of Mormon, the D&C and the Pearl of Great Price.
The Book of Mormon is a foundational sacred book for the church; the terms "Mormon" and "Mormonism" come from the book itself. The LDS Church teaches that the Angel Moroni told Smith about golden plates containing the record, guided him to find them buried in the Hill Cumorah, and provided him the means of translating them from Reformed Egyptian. It claims to give a history of the inhabitants from a now-extinct society living on the American continent and their distinct Judeo-Christian teachings. The Book of Mormon is very important to modern Latter-day Saints, who consider it the world's most perfect text.
The Bible, also part of the church's canon, is believed to be the word of God—subject to an acknowledgment that its translation may be incorrect, or that authoritative sections may have been lost over the centuries. Most often, the church uses the Authorized King James Version. Two extended portions of the Joseph Smith Translation of the Bible have been canonized and are thus considered authoritative. Additionally, over 600 of the more doctrinally significant verses from the translation are included as excerpts in the current LDS Church edition of the Bible. Other revelations from Smith are found in the D&C, and in the Pearl of Great Price. Another source of authoritative doctrine is the pronouncements of the current Apostles and members of the First Presidency. The church teaches that the First Presidency and the Quorum of Twelve Apostles are prophets and that they are therefore authorized teachers of God's word.
In addition to doctrine given by the church as a whole, individual members of the church believe that they can also receive personal revelation from God in conducting their lives, and in revealing truth to them, especially about spiritual matters. Generally, this is said to occur through thoughts and feelings from the Holy Ghost, in response to prayer. Similarly, the church teaches its members may receive individual guidance and counsel from God through blessings from priesthood holders. In particular, patriarchal blessings are considered special blessings that are received only once in the recipient's life, which are recorded, transcribed, and archived.
In the church, an ordinance is a sacred rite or ceremony that has spiritual and symbolic meanings, and acts as a means of conveying divine grace. Ordinances are physical acts which signify or symbolize an underlying spiritual act; for some ordinances, the spiritual act is the finalization of a covenant between the ordinance recipient and God. Ordinances are generally performed under priesthood authority.
The ordinance of baptism is believed to bind its participant to Jesus Christ, who saves them in their imperfection if they continually keep their promises to him. Baptism is performed by immersion, and is typically administered to children starting at age eight.
Church members believe that through the ordinances of temple sealing and temple endowment, anyone can reach the highest level of salvation in the celestial kingdom and eternally live in God's presence, continue as families, become gods, create worlds, and make spirit children over whom they will govern.
Other ordinances performed in the church include confirmation, the sacrament (analogous to the Eucharist or holy communion), and priesthood ordination.
The LDS Church asks its members to adhere to a dietary code called the Word of Wisdom, in which they abstain from the consumption of alcohol, coffee, tea, tobacco, and illicit or harmful substances. The Word of Wisdom also encourages the consumption of herbs and grains along with the moderate consumption of meat.
When Joseph Smith published the Word of Wisdom in 1833, it was considered only advice; violation did not restrict church membership. During the 1890s, though, church leaders started emphasizing the Word of Wisdom more. In 1921, church president Heber J. Grant made obeying the Word of Wisdom a requirement to engage in worship inside of the faith's temples. From that time, church leadership has emphasized the forbidding of coffee, tea, tobacco, and alcohol, but not the other guidelines concerning meat, grains, and herbs.
Church members are expected to follow a moral code called the law of chastity, which prohibits adultery, homosexual behavior, and sexual relations before or outside of marriage. As part of the law of chastity, the church strongly opposes pornography, and considers masturbation an immoral act.
Church members are expected to donate one-tenth of their income to support the operations of the church (e.g. temple and meetinghouse operation and construction, etc.), with an estimated annual donation of $7 billion to $33 billion USD donated in 2012 (equivalent to $8.9 billion to $42.1 billion in 2022). In order to qualify for temple ordinances necessary for salvation, paying a full tithe is a requirement, regardless of one's temporal circumstances. Members are also encouraged to fast (abstain from food and drink) on the first Sunday of each month for two consecutive meals. They donate at least the cost of the two skipped meals of the fast as a "fast offering", which the church uses to assist people in need and expand its humanitarian efforts.
Local leadership is not paid, and is expected to tithe as well. Full-time missionaries, however, are not expected to pay tithing as they are usually paying to be a missionary.
Starting in the late 1960s, serving a two-year, full-time proselytizing mission became expected for all able-bodied LDS young men. Missionaries do not choose where they serve or the language in which they will proselytize, and are expected to fund their missions themselves or with the aid of their families. Prospective male missionaries must be at least 18 years old and no older than 25, and have completed secondary school. Missionary service is not compulsory, nor is it required for young men to retain their church membership.
Unmarried women 19 years and older may also serve as missionaries, generally for a term of 18 months. there is no maximum age for missionary service for women.
Retired couples are also encouraged to serve missions, and may serve from 6–23 months terms. Unlike younger missionaries, these senior missionaries may serve in non-proselytizing capacities such as humanitarian aid workers or family history specialists. Other men and women who desire to serve a mission, but may not be able to perform full-time service in another state or country due to health issues, may serve in a non-proselytizing mission. They might assist at Temple Square in Salt Lake City or aid in the seminary system in schools.
All proselytizing missionaries are organized geographically into administrative areas called missions. The efforts in each mission are directed by an older adult male mission president. As of July 2020, there were 407 missions of the church.
Church members are expected to set aside Sundays as a day of rest and worship. Typically, weekly worship meetings occur solely on Sundays. Shopping and recreation are discouraged on Sundays as well.
Meetings for worship and study are held at meetinghouses, which are typically utilitarian in character. The main focus of Sunday worship is the Sacrament meeting, where the sacrament is passed to church members; sacrament meetings also include prayers, the singing of hymns by the congregation or choir, and impromptu or planned sermons by church members. Also included in weekly meetings are times for Sunday School, or separate instructional meetings based on age and gender, including the Relief Society for women.
Church congregations are organized geographically. Members are generally expected to attend the congregation with their assigned geographical area; however, some geographical areas also provide separate congregations for young single adults, older single adults, or for speakers of alternate languages. For Sunday services, the church is grouped into either larger congregations known as wards, or smaller congregations known as branches. Regional church organizations, encompassing multiple congregations, include stakes, missions, districts and areas.
The church's Young Men and Young Women organizations meet at the meetinghouse once a week, on a day other than Sunday, where the youth participate in activities.
In LDS theology, a temple is considered to be a holy building, dedicated as a "House of the Lord" and held as more sacred than a typical meetinghouse or chapel. In temples, church members participate in ceremonies that are considered the most sacred in the church, including marriage, and an endowment ceremony that includes a washing and anointing, receiving a temple garment, and making covenants with God. Baptisms for the dead—as well as other temple ordinances on behalf of the dead—are performed in the temples as well.
Temples are considered by church members to be the most sacred structures on earth, and as such, operating temples are not open to the public. Permission to enter is reserved only for church members who pass periodic interviews with ecclesiastical leaders and receive a special recommendation card, called a temple recommend, that they present upon entry. Church members are instructed not to share details about temple ordinances with non-members or even converse about them outside the temple itself. As of May 2023, there are 177 operating temples worldwide.
In order to perform ordinances in temples on behalf of deceased family members, the church emphasizes genealogical research, and encourages its lay members to participate in genealogy. It operates FamilySearch, the largest genealogical organization in the world.
Twice each year, general authorities address the worldwide church through general conference. General conference sessions are translated into as many as 80 languages and are broadcast from the 21,000-seat Conference Center in Salt Lake City. During this conference, church members formally acknowledge, or "sustain", the First Presidency and Quorum of the Twelve Apostles as prophets, seers, and revelators.
Individual stakes also hold formal conferences within their own boundaries biannually; wards hold conferences annually.
The church teaches that it is a continuation of the Church of Christ established in 1830 by Joseph Smith. This original church underwent several name changes during the 1830s, being called the Church of Christ and the Church of Jesus Christ; in 1834, the name was officially changed to the Church of the Latter Day Saints. In April 1838, the name was officially changed to "The Church of Jesus Christ of Latter Day Saints". After Smith died, Brigham Young and the largest body of Smith's followers incorporated the LDS Church in 1851 by legislation of the State of Deseret under the name "The Church of Jesus Christ of Latter-day Saints", which included a hyphenated "Latter-day" and a British-style lower-case d.
Common informal names for the church include the LDS Church, the Latter-day Saints, and the Mormons. The term Mormon Church is in common use. The church requests that the official name be used when possible or, if necessary, shortened to "the Church", "the Church of Jesus Christ", or "Latter-day Saints". In August 2018, church president Russell M. Nelson asked members of the church and others to cease using the terms "LDS", "Mormon" and "Mormonism" to refer to the church, its membership, or its belief system and instead to call the church by its full and official name. Subsequent to this announcement, the church's premier vocal ensemble, the Mormon Tabernacle Choir, was officially renamed and became the "Tabernacle Choir at Temple Square". Reaction to the name change policy has been mixed.
Legally, the church currently functions as a corporation sole, incorporated in Utah.
Intellectual Reserve is a nonprofit corporation wholly owned by the church, which holds the church's intellectual property, such as copyrights, trademarks, and other media.
The LDS Church is organized in a hierarchical priesthood structure administered by its male members. Members of the church-wide leadership are called general authorities. They exercise both ecclesiastical and administrative leadership over the church and direct the efforts of regional leaders down to the local level. General authorities and mission presidents work full-time for the church, and typically receive stipends from church funds or investments. As well as speaking in general conference, general authorities speak to church members in local congregations throughout the world; they also speak to youth and young adults in broadcasts and at the Church Educational System (CES) schools, such as Brigham Young University (BYU). Local congregations are typically led by bishops, who perform similar functions to pastors in the Protestant tradition, or parish priests in the Roman Catholic Church.
All males who are living the standards of the church are generally considered for the priesthood and are ordained to the priesthood as early as age 11. Ordination occurs by a ceremony where hands are laid on the head of the one ordained. The priesthood is divided into an order for young men aged 11 years and older (called the Aaronic priesthood) and an order for men 18 years of age and older (called the Melchizedek priesthood). Additional authorities within the priesthood – called priesthood keys – are extended to holders of certain church leadership callings.
Some church leaders and scholars have spoken of women holding or exercising priesthood power. However, women are not formally ordained to the priesthood, and they do not participate in public functions administered by the priesthood—such as passing the Sacrament, giving priesthood blessings, or holding leadership positions over congregations as a whole. Since 2013, the Ordain Women organization has sought formal priesthood ordination for women.
Each active church member is expected to receive a calling, or position of assigned responsibility within the church. Church members are expected to neither ask for specific callings, nor decline callings that are extended to them by their leaders. Leadership positions in the church's various congregations are filled through the calling system, and the vast majority of callings are filled on a volunteer basis. Members volunteer general custodial work for local church facilities.
Under the leadership of the priesthood hierarchy are five organizations that fill various roles in the church: Relief Society, the Young Men and Young Women organizations, Primary, and Sunday School. Women serve as presidents and counselors in the presidencies of the Relief Society, Young Women, and Primary, while men serve as presidents and counselors of the Young Men and Sunday School. The church also operates several programs and organizations in the fields of proselytizing, education, and church welfare such as LDS Humanitarian Services. Many of these organizations and programs are coordinated by the Priesthood Correlation Program, which is designed to provide a systematic approach to maintain worldwide consistency, orthodoxy, and control of the church's ordinances, doctrines, organizations, meetings, materials, and other programs and activities.
The church operates CES, which includes BYU, BYU–Idaho, BYU–Hawaii, and Ensign College. The church also operates Institutes of Religion near the campuses of many colleges and universities. For high-school aged youth, the church operates a four-year Seminary program, which provides religious classes for students to supplement their secular education. The church also sponsors a low-interest educational loan program known as the Perpetual Education Fund, which provides educational opportunities to students from developing nations.
The church's welfare system, initiated in 1930 during the Great Depression, provides aid to the poor. Leaders ask members to fast once a month and donate the money they would have spent on those meals to help the needy, in what is called a fast offering. Money from the program is used to operate Bishop's storehouses, which package and store food at low cost. Distribution of funds and food is administered by local bishops. The church also distributes money through its Philanthropies division to disaster victims worldwide.
Other church programs and departments include Family Services, which provides adoption resource referrals, marital and family counseling, psychotherapy, and addiction counseling; the LDS Church History Department, which collects church history and records; and the Family History Department, which administers the church's large family history efforts, including FamilySearch, the world's largest family history library and organization. Other facilities owned and operated by the church include Temple Square, the Church Office Building, the Church Administration Building, the Church History Library and the Granite Mountain Records Vault.
Since 1941, the church has been classified by the IRS as a 501(c)(3) organization and is therefore tax-exempt. Donations are tax-deductible in the United States. The church has not released church-wide financial statements since 1959. In the absence of official statements, people interested in knowing the church's financial status and behavior, including both members of the church and people outside the church, have attempted to estimate or guess.
In 1997, Time magazine called the LDS Church one of the world's wealthiest churches per capita. The church has stated that its for-profit, non-profit, and educational subsidiary entities are all audited by professionals independent from other church entities.
The church receives significant funds from tithes and fast offerings. It has been estimated that during the 2010s its net worth increased by about $15 billion per year ($18.5 billion in 2022), and by $22 billion during the COVID-19 pandemic. According to a 2020 estimate by The Wall Street Journal, the LDS Church's investment fund had a net worth of around $100 billion.
The church's assets are held in a variety of holding companies, subsidiary corporations, and for-profit companies including: Bonneville International, KSL, Deseret Book Company, and holding companies for cattle ranches and farms in at least 12 U.S. States, Canada, New Zealand, and Argentina. Also included are banks and insurance companies, hotels and restaurants, real estate development, forestry and mining operations, and transportation and railway companies. Investigative journalism from the Truth & Transparency Foundation in 2022 suggests the church may be the owner of the most valuable real estate portfolio in the United States, with a minimum market value of $15.7 billion. The church has also invested in for-profit business and real estate ventures such as City Creek Center. The Church-owned investment firm Ensign Peak Advisors publicly reports management of $37.8 billion of financial securities, as of 2020.
Due to the differences in lifestyle promoted by church doctrine and history, members of the church have developed a distinct culture. It is primarily concentrated in the Intermountain West.
Many of the church's more distinctive practices follow from their adherence to the Word of Wisdom—which includes abstinence from tobacco, alcohol, coffee, and tea—and their observance of Sabbath-day restrictions on recreation and shopping. Common, distinctive cuisine includes funeral potatoes and Jello salad. Cultural taboos exist on piercings and tattoos and the church counsels against the use of crosses as symbols of worship.
LDS-themed media includes cinema, fiction, websites, and graphical art such as photography and paintings. The church owns a chain of bookstores called Deseret Book, which provide a channel through which publications are sold; church leaders have authored books and sold them through the publishing arm of the bookstore. BYU TV, the church-sponsored television station, also airs on several networks. The church also produces several pageants annually depicting various events of the primitive and modern-day church. Its Easter pageant Jesus the Christ has been identified as the "largest annual outdoor Easter pageant in the world". The church encourages entertainment without violence, sexual content, or vulgar language; many church members specifically avoid rated-R movies.
The church's official choir, the Tabernacle Choir at Temple Square, was formed in the mid-19th century and performs in the Salt Lake Tabernacle. They have travelled to more than 28 countries, and are considered one of the most famous choirs in the world. The choir has received a Grammy Award, four Emmy Awards, two Peabody Awards, and the National Medal of Arts.
The LDS Church states it generally takes no partisan role in politics, but encourages its members to play an active role as responsible citizens in their communities, including becoming informed about issues and voting. The church maintains that the faith's values can be found among many political parties. It also generally does not take sides in global conflicts.
A 2012 Pew Center on Religion and Public Life survey indicates that 74 percent of U.S. members lean towards the Republican Party. Some liberal members say they feel that they have to defend their worthiness due to political differences. Democrats and those who lean Democrat made up 18% of church members surveyed in the 2014 Pew Research Center's Religious Landscape Survey.
The official church stance on staying out of politics does not include if there are instances of what church leaders deem to be moral issues, or issues the church believes "directly affect [its] mission, teachings or operations." It has previously opposed same-sex marriage in California Prop 8, supported a gay rights bill in Salt Lake City which bans discrimination against homosexual persons in housing and employment, opposed gambling, opposed storage of nuclear waste in Utah, and supported an approach to U.S. immigration policy as outlined in the Utah Compact. It also opposed a ballot initiative legalizing medicinal marijuana in Utah, but supported a possible alternative to it. In 2019 and 2021, the church stated its opposition to the Equality Act, which would prohibit discrimination in the United States on the basis of sexual orientation and gender identity, but supports alternate legislation that it says would protect both LGBTQ rights and religious freedom. In 2022, the church stated its support for the Respect for Marriage Act—which codified same-sex marriage as legal in the United States—due to the "protections for religious freedom" it includes.
In the 117th United States Congress, there are nine LDS Church members, including all six members of Utah's congressional delegation, all of whom are Republicans. Utah's current governor, Spencer Cox, is also a church member, as are supermajorities in both houses of the Utah State Legislature. Church member and current U.S. Senator Mitt Romney was the Republican Party's nominee in the U.S. 2012 presidential election.
The church reports a worldwide membership of 17 million. The church's definition of "membership" includes all persons who were ever baptized, or whose parents were members while the person was under the age of eight (called "members of record"), who have neither been excommunicated nor asked to have their names removed from church records. As of December 2011, approximately 8.3 million members reside outside the United States.
According to its statistics, the church is the fourth largest religious body in the United States. Although the church does not publish attendance figures, researchers estimate that attendance at weekly LDS worship services globally is around 4 million. Members living in the U.S. and Canada constitute 46 percent of membership, Latin America 38 percent, and members in the rest of the world 16 percent. The 2012 Pew Forum on Religion & Public Life survey, conducted by Princeton Survey Research Associates International, found that approximately 2 percent of the U.S. adult population self-identified as Mormon.
Membership is concentrated geographically in the Intermountain West, in a specific region sometimes known as the Mormon corridor. Church members and some others from the United States colonized this region in the mid-to-late 1800s, dispossessing several indigenous tribes in the process.
The church experienced rapid numerical growth in the 20th century, especially in the 1980s and 1990s. In the 21st century, however, church membership growth has slowed. In 2022, eight of the top ten nations with the highest LDS membership growth rate were in Africa, and Latino people are one of the fastest growing ethnic groups with millions of LDS adherents in Latin American countries.
In the United States, church members tend to be more highly educated than the general population. The racial and ethnic composition of membership in the United States is one of the least diverse in the country. Church membership is predominantly white; the membership of blacks is significantly lower than the general U.S. population.
The LDS Church does not release official statistics on church activity, but it is likely that only approximately 40 percent of its recorded membership in the United States and 30 percent worldwide regularly attend weekly Sunday worship services. A 2016 survey found a majority (54%) of millennials raised in the church had disaffiliated. Activity rates vary with age, and disengagement occurs most frequently between age 16 and 25. Young single adults are more likely to become inactive than their married counterparts, and women tend to be more active than men.
The LDS Church is widely known for providing worldwide humanitarian service. The church's welfare and humanitarian efforts are coordinated by Philanthropies, a church department under the direction of the Presiding Bishopric. Welfare efforts, originally initiated during the Great Depression, provide aid for the poor, financed by donations from church members. Philanthropies is also responsible for philanthropic (that is, not tithing or fast offering) donations to the LDS Church and other affiliated charities, such as the Church History Library, the Church Educational System (and its subsidiary organizations), the Tabernacle Choir at Temple Square and funds for LDS missionaries. Donations are also used to operate bishop's storehouses, which package and store food for lower-income people at low cost, and provide other local services. In 2016, the church reported that it had spent a total of $1.2 billion on humanitarian aid over the previous 30 years.
Church humanitarian aid includes organizing food security, clean water, mobility, and healthcare initiatives, operating thrift stores, maintaining a service project website, and directly funding or partnering with other organizations. The church reports that the value of all charitable donations in 2021 was $906 million. Independent reporting has found that the Church's charity organization, LDS Charities, gave a total of $177 million from 2008 to 2020.
The church also distributes money and aid to disaster victims worldwide. In 2017, the church partnered with Catholic Relief Services and other organizations to provide aid to several African and Middle Eastern nations. In 2010, it partnered with Islamic Relief to help victims of flooding in Pakistan. Latter-day Saint Charities (a branch of the church's welfare department) increased food production during the COVID-19 pandemic and donated healthcare supplies to 16 countries affected by the crisis. The church has donated $4 million to aid refugees fleeing from the 2022 Russian invasion of Ukraine. In 2022, the church gave $32 million to the United Nations World Food Programme, in its largest one-time donation to a humanitarian organization to that point.
The LDS Church has been subject to criticism and the subject of controversy since its early years in New York and Pennsylvania.
Modern criticism of the church includes disputed claims, allegations of historical revisionism by the church, child sexual abuse, anti-gay teachings, racism, and sexism. Notable 20th-century critics include Jerald and Sandra Tanner and historian Fawn Brodie.
The church has been criticized for a number of alleged abuses perpetrated by local church leadership. In other cases, church leaders have been criticized for allegedly failing to properly report abuse to law enforcement.
In the late 1820s, criticism centered on the claim by Joseph Smith to have been led to a set of gold plates from which the Book of Mormon was reputedly translated.
Mainstream archaeological, historical, and scientific communities have discovered little to support the existence of the civilizations described in the Book of Mormon, and do not consider it to be an actual record of historical events. Scholars have pointed out a number of anachronisms within the text. They argue that no evidence of a reformed Egyptian language has ever been discovered; the Book of Mormon explicitly claims to have been written in reformed Egyptian, and so the non-existence of this language would challenge the book's claims about its own origin. Also, general archaeological and genetic evidence has not supported the book's statements about any known indigenous peoples of the Americas.
Since its publication in 1842, the Book of Abraham (currently published as part of the canonical Pearl of Great Price) has also been a major source of controversy. Numerous non-Mormon Egyptologists, beginning in the late 19th century, have disagreed with Joseph Smith's explanations of the book's facsimiles. Translations of the original papyri—by both Mormon and non-Mormon Egyptologists—do not match the text of the Book of Abraham as purportedly translated by Joseph Smith. Indeed, the transliterated text from the recovered papyri and facsimiles published in the Book of Abraham contain no direct references to Abraham. Scholars have also asserted that damaged portions of the papyri were reconstructed incorrectly by Smith or his associates.
Polygamy (called plural marriage within the church) was practiced by church leaders for more than half of the 19th century, and practiced publicly from 1852 to 1890 by between 20 and 30 percent of Latter-day Saint families. It was instituted privately in the 1830s by founder Joseph Smith and announced publicly in 1852 at the direction of Brigham Young.
For over 60 years, the church and the United States were at odds over the issue: at one point, the Republican platform referenced "the twin relics of barbarism—polygamy and slavery." The church defended the practice as a matter of religious freedom, while the federal government aggressively sought to eradicate it; in 1862, the United States Congress passed the Morrill Anti-Bigamy Act, which prohibited plural marriage in the territories.
In 1890, church president Wilford Woodruff issued a Manifesto that officially terminated the practice in the United States, though it did not dissolve existing polygamous marriages of any couples, some of which continued to cohabit into the 1950s. Some church members continued to enter into polygamous marriages in Canada and Mexico, but these eventually stopped in 1904 when church president Joseph F. Smith disavowed polygamy before Congress and issued a "Second Manifesto," calling for all plural marriages in the church to cease. Several small fundamentalist groups, seeking to continue the practice, split from the LDS Church, but the mainline church now excommunicates members found practicing polygamy and distances itself from those fundamentalist groups.
The teachings, attitudes, and practices of top LDS Church leaders towards Black people have changed significantly from its founding years to the modern times, and the church has faced criticism and controversy on these topics. Joseph Smith allowed several black men to be ordained as priests during his presidency, but also taught that the dark skin of people of Black African ancestry was a sign of a curse from God. Both Smith and Brigham Young taught that Black people were subject to the Biblical curse of Ham, and curse of Cain. Both made statements in support of Black enslavement, and Young legalized Black slavery while acting as Utah territory's governor.
From 1844 to 1978, the church barred Black women and men from participating in temple ordinances necessary for the highest level of salvation; prevented most men of Black African descent from being ordained to the church's lay, all-male priesthood; supported racial segregation in its communities and schools; taught that righteous Black people would be made White after death; and opposed interracial marriage. Leaders taught on many occasions during this time that Black people were less righteous in the pre-existence. The temple and priesthood racial restrictions were lifted by top leaders in 1978 following public pressure during the United States' civil rights movement. In 2013 the church directly disavowed its previous teachings on race for the first time. In 2018, the Church formed an alliance with the NAACP in an effort to improve race relations.
Over the past two centuries, the relationship between Native American people and the LDS Church has included friendly ties, displacement, battles, slavery, education placement programs, official and unofficial discrimination, and criticism. Church leadership and publications taught that Native Americans are descendants of Lamanites, a dark-skinned and cursed people from the Book of Mormon. More recently, LDS researchers and publications generally favor a smaller geographic footprint of Lamanite descendants. There is no direct support amongst mainstream historians and archaeologists for the historicity of the Book of Mormon or Middle Eastern origins for any Native American peoples.
Soon after Mormons colonized the Salt Lake Valley in 1847, Native American child slaves became a vital source of their labor, and were exchanged as gifts. The settlers initially had some peaceful relations, but because resources were scarce in the desert, hostilities broke out with the local Native Americans. According to LDS Church Historian Marlin K. Jensen as more LDS immigrants arrived and took over the land of Native nations, "Resources the Indians had relied on for generations diminished, and in time they felt forced to resist and fight for their own survival ... the land and cultural birthright Indians once possessed in the Great Basin were largely taken from them." Within 50 years of Mormon settlement, the population of Utah's Native Americans was reduced by almost 90%.
The church ran an Indian Placement Program between the 1950s and the 1990s, wherein indigenous children were adopted by white church members. Criticism resulted during and after the program, including claims of improper assimilation and even abuse. However, many of the involved students and families praised the program. Church leaders taught for decades that Native Americans' darker skin would be made lighter due to their righteousness.
The church's policies and treatment of sexual minorities and gender minorities have long been the subject of external criticism, as well as internal controversy and disaffection by members. Because of its ban against same-sex sexual activity and same-sex marriage, the LDS church taught for decades that any adherents attracted to the same sex could and should change that through sexual orientation change efforts and righteous striving. The church provided therapy and programs for attempting to change sexual orientation.
Current teachings and policies leave homosexual members with the options of: attempts to change their sexual orientation, entering a mixed-orientation opposite-sex marriage, or lifelong celibacy. Some have argued that church teachings against homosexuality and the treatment of LGBT members by other adherents and leaders have contributing to their elevated rates of PTSD and depression, as well as suicide and teen homelessness. The church's decades-long, political involvement opposing US same-sex marriage laws has further garnered criticism and protests.
In the 1830s, the church was heavily criticized for Smith's handling of a banking failure in Kirtland, Ohio. After the Mormons migrated west, there was fear and suspicion about the LDS Church's political and military power in Missouri, culminating in the 1838 Mormon War and the Mormon Extermination Order (Missouri Executive Order 44) by Governor Lilburn Boggs. In the 1840s, criticism of the church included its theocratic aspirations in Nauvoo, Illinois. Criticism of the practice of plural marriage and other doctrines taught by Smith were published in the Nauvoo Expositor in 1844. After Smith took a leading role in having the paper's printing press destroyed, he was charged with treason and jailed. While he awaited trial, an angry mob stormed the jailhouse and shot him fatally.
In modern popular opinion, non-Mormons in the U.S. generally consider Smith a "charlatan, scoundrel, and heretic." The Book of Mormon musical relentlessly mocks his account of the golden plates. In 2007, Christopher Hitchens, writing in Slate magazine, lambasted Smith as a mountebank, charlatan, and fraud (and the church itself as a "ridiculous cult" and a "racket" that became a religion).
The church's failure to make its finances public has drawn criticism from commentators who consider its practices too secretive.
In December 2019, a whistleblower alleged the church held over $100 billion in investment funds through its investment management company, Ensign Peak Advisors (EP); that it failed to use the funds for charitable purposes and instead used them in for-profit ventures; and that it misled contributors and the public about the usage and extent of those funds. In response, the church's First Presidency stated that "the Church complies with all applicable law governing our donations, investments, taxes, and reserves," and that "a portion" of funds received by the church are "methodically safeguarded through wise financial management and the building of a prudent reserve for the future". The church has not directly addressed the fund's size to the public, but third parties have treated the disclosures as legitimate. The disclosure of Ensign Peak has led to criticism that the church's wealth may be excessive.
The church has been accused of significant tax evasion in Australia. According to an investigation by Australian newspapers, The Daily Age and The Sun Herald, the church's corporation LDS Charities Australia was the recipient of nearly $70 million in donations annually (which is tax exempt under Australian law, as opposed to religious donations, which are not) but appeared to actually spend very little of it on charity. According to the investigation, tithing and other religious donations were routed through the corporation to ensure they would be tax exempt. The investigation does not reference any internal church documents to confirm their findings. The church has previously fought to keep its internal financial information out of the public record. In July 2023, the Sydney Morning Herald reported the church "has moved to unwind the tax structure" at issue.
The church has transferred more than 1 billion dollars of tithing collected in Canada, tax-free, to church universities over a 15-year period. In October 2022, The Sydney Morning Herald announced that while the church publicly claimed to have donated US$1.35 billion to charity between 2008 and 2020, its private financial reports showed that it donated only US$0.177 billion.
In February 2023, the U.S. Securities and Exchange Commission (SEC) issued a $5 million penalty to the church and its investment company, EP. The SEC alleged that the church concealed its investments and their management in multiple shell companies from 1997 to 2019; the SEC believes these shell companies were approved by senior church leadership to avoid public transparency. The church released a statement that in 2000 EP "received and relied upon legal counsel regarding how to comply with its reporting obligations while attempting to maintain the privacy of the portfolio." After initial SEC concern in June 2019, the church stated that EP "adjusted its approach and began filing a single aggregated report."
Mormon apologetics organizations, such as FAIR and the Maxwell Institute, seek to counter criticisms of the church and its leaders. Most of the apologetic work focuses on providing and discussing evidence supporting the claims of Smith and the Book of Mormon. Scholars and authors such as Hugh Nibley, Daniel C. Peterson, and others are well-known apologists within the church. The Foundation for Ancient Research and Mormon Studies (FARMS) was a well-known apologetic organization before being absorbed into the Maxwell Institute in 2006. | [

Nevertheless, the church flourished in Kirtland as Smith published new revelations and the church built the Kirtland Temple,}} culminating in a dedication of the building similar to the day of Pentecost. The Kirtland era ended in 1838, after a financial scandal rocked the church and caused widespread defections. Smith regrouped with the remaining church in Far West, Missouri, but tensions soon escalated into violent conflicts with the old Missouri settlers. Believing the Latter Day Saints to be in insurrection, the Missouri governor ordered that they be \"exterminated or driven from the State\".

Soon thereafter, church president Wilford Woodruff issued a manifesto that officially suspended the performance of new polygamous marriages in the United States.

] | The Church of Jesus Christ of Latter-day Saints, informally known as the LDS Church or Mormon Church, is a restorationist, nontrinitarian Christian denomination that is the largest denomination in the Latter Day Saint movement. The church is headquartered in the United States in Salt Lake City, Utah and has established congregations and built temples worldwide. According to the church, it has over 17 million members and over 72,000 full-time volunteer missionaries. The church was the fourth-largest Christian denomination in the United States as of 2012, and reported over 6.8 million US members as of 2022. The church was founded as the Church of Christ in western New York, in 1830 by Joseph Smith during the Second Great Awakening. Under Smith's leadership, the church's headquarters moved successively to Ohio, Missouri, and Illinois. After Smith's 1844 death and a resultant succession crisis, the majority of his followers sided with Brigham Young, who led the church to its current headquarters in Salt Lake City. Young and his successors continued the church's growth, first throughout the Intermountain West, and more recently as a national and international organization. Church theology includes the Christian doctrine of salvation through Jesus Christ, and his substitutionary atonement on behalf of mankind. The church has an open canon of four scriptural texts: the Bible, the Book of Mormon, the Doctrine and Covenants (D&C), and the Pearl of Great Price. Other than the Bible, the majority of the church canon consists of material the church's members believe to have been revealed by God to Joseph Smith, including commentary and exegesis about the Bible, texts described as lost parts of the Bible, and other works believed to be written by ancient prophets, including the Book of Mormon. Because of doctrinal differences, many Christian groups consider the church to be distinct and separate from mainstream Christianity. Members of the church, known as Latter-day Saints or Mormons, believe that the church president is a modern-day "prophet, seer, and revelator" and that Jesus Christ, under the direction of God the Father, leads the church by revealing his will and delegating his priesthood keys to its president. The president heads a hierarchical structure descending from areas to stakes and wards. The church has a volunteer clergy at the local and regional levels; wards are led by bishops, who are drawn from the membership of the wards themselves. Male members may be ordained to the priesthood, provided they are living the standards of the church. Women are not ordained to the priesthood, but occupy leadership roles in some church organizations. Both men and women may serve as missionaries. The church maintains a large missionary program that proselytizes and conducts humanitarian services worldwide. The church also funds and participates in humanitarian projects independent of its missionary efforts. Faithful members adhere to church laws of sexual purity, health, fasting, and Sabbath observance, and contribute ten percent of their income to the church in tithing. The church teaches sacred ordinances through which adherents make covenants with God, including baptism, confirmation, the sacrament, priesthood ordination, endowment and celestial marriage. The church has been criticized throughout its history. Modern criticisms include disputes over the church's historical claims, treatment of minorities, and finances. The church's practice of polygamy was controversial until it was curtailed in 1890 and officially rescinded in 1904. | 2001-10-30T09:24:44Z | 2023-12-29T12:07:08Z | [

5,936 | Chemical thermodynamics | Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Chemical thermodynamics involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the study of chemical questions and the spontaneity of processes.
The structure of chemical thermodynamics is based on the first two laws of thermodynamics. Starting from the first and second laws of thermodynamics, four equations called the "fundamental equations of Gibbs" can be derived. From these four, a multitude of equations, relating the thermodynamic properties of the thermodynamic system can be derived using relatively simple mathematics. This outlines the mathematical framework of chemical thermodynamics.
In 1865, the German physicist Rudolf Clausius, in his Mechanical Theory of Heat, suggested that the principles of thermochemistry, e.g. the heat evolved in combustion reactions, could be applied to the principles of thermodynamics. Building on the work of Clausius, between the years 1873-76 the American mathematical physicist Willard Gibbs published a series of three papers, the most famous one being the paper On the Equilibrium of Heterogeneous Substances. In these papers, Gibbs showed how the first two laws of thermodynamics could be measured graphically and mathematically to determine both the thermodynamic equilibrium of chemical reactions as well as their tendencies to occur or proceed. Gibbs’ collection of papers provided the first unified body of thermodynamic theorems from the principles developed by others, such as Clausius and Sadi Carnot.
During the early 20th century, two major publications successfully applied the principles developed by Gibbs to chemical processes and thus established the foundation of the science of chemical thermodynamics. The first was the 1923 textbook Thermodynamics and the Free Energy of Chemical Substances by Gilbert N. Lewis and Merle Randall. This book was responsible for supplanting the chemical affinity with the term free energy in the English-speaking world. The second was the 1933 book Modern Thermodynamics by the methods of Willard Gibbs written by E. A. Guggenheim. In this manner, Lewis, Randall, and Guggenheim are considered as the founders of modern chemical thermodynamics because of the major contribution of these two books in unifying the application of thermodynamics to chemistry.
The primary objective of chemical thermodynamics is the establishment of a criterion for determination of the feasibility or spontaneity of a given transformation. In this manner, chemical thermodynamics is typically used to predict the energy exchanges that occur in the following processes:
The following state functions are of primary concern in chemical thermodynamics:
Most identities in chemical thermodynamics arise from application of the first and second laws of thermodynamics, particularly the law of conservation of energy, to these state functions.
The three laws of thermodynamics (global, unspecific forms):
1. The energy of the universe is constant.
2. In any spontaneous process, there is always an increase in entropy of the universe.
3. The entropy of a perfect crystal (well ordered) at 0 Kelvin is zero.
Chemical energy is the energy that can be released when chemical substances undergo a transformation through a chemical reaction. Breaking and making chemical bonds involves energy release or uptake, often as heat that may be either absorbed by or evolved from the chemical system.
Energy released (or absorbed) because of a reaction between chemical substances ("reactants") is equal to the difference between the energy content of the products and the reactants. This change in energy is called the change in internal energy of a chemical system. It can be calculated from Δ f U r e a c t a n t s o {\displaystyle \Delta _{\rm {f}}U_{\mathrm {reactants} }^{\rm {o}}} , the internal energy of formation of the reactant molecules related to the bond energies of the molecules under consideration, and Δ f U p r o d u c t s o {\displaystyle \Delta _{\rm {f}}U_{\mathrm {products} }^{\rm {o}}} , the internal energy of formation of the product molecules. The change in internal energy is equal to the heat change if it is measured under conditions of constant volume (at STP condition), as in a closed rigid container such as a bomb calorimeter. However, at constant pressure, as in reactions in vessels open to the atmosphere, the measured heat is usually not equal to the internal energy change, because pressure-volume work also releases or absorbs energy. (The heat change at constant pressure is called the enthalpy change; in this case the widely tabulated enthalpies of formation are used.)
A related term is the heat of combustion, which is the chemical energy released due to a combustion reaction and of interest in the study of fuels. Food is similar to hydrocarbon and carbohydrate fuels, and when it is oxidized, its energy release is similar (though assessed differently than for a hydrocarbon fuel — see food energy).
In chemical thermodynamics, the term used for the chemical potential energy is chemical potential, and sometimes the Gibbs-Duhem equation is used.
In most cases of interest in chemical thermodynamics there are internal degrees of freedom and processes, such as chemical reactions and phase transitions, which create entropy in the universe unless they are at equilibrium or are maintained at a "running equilibrium" through "quasi-static" changes by being coupled to constraining devices, such as pistons or electrodes, to deliver and receive external work. Even for homogeneous "bulk" systems, the free-energy functions depend on the composition, as do all the extensive thermodynamic potentials, including the internal energy. If the quantities { Ni }, the number of chemical species, are omitted from the formulae, it is impossible to describe compositional changes.
For an unstructured, homogeneous "bulk" system, there are still various extensive compositional variables { Ni } that G depends on, which specify the composition (the amounts of each chemical substance, expressed as the numbers of molecules present or the numbers of moles). Explicitly,
For the case where only PV work is possible,
a restatement of the fundamental thermodynamic relation, in which μi is the chemical potential for the i-th component in the system
The expression for dG is especially useful at constant T and P, conditions, which are easy to achieve experimentally and which approximate the conditions in living creatures
While this formulation is mathematically defensible, it is not particularly transparent since one does not simply add or remove molecules from a system. There is always a process involved in changing the composition; e.g., a chemical reaction (or many), or movement of molecules from one phase (liquid) to another (gas or solid). We should find a notation which does not seem to imply that the amounts of the components ( Ni ) can be changed independently. All real processes obey conservation of mass, and in addition, conservation of the numbers of atoms of each kind.
Consequently, we introduce an explicit variable to represent the degree of advancement of a process, a progress variable ξ for the extent of reaction (Prigogine & Defay, p. 18; Prigogine, pp. 4–7; Guggenheim, p. 37.62), and to the use of the partial derivative ∂G/∂ξ (in place of the widely used "ΔG", since the quantity at issue is not a finite change). The result is an understandable expression for the dependence of dG on chemical reactions (or other processes). If there is just one reaction
If we introduce the stoichiometric coefficient for the i-th component in the reaction
(negative for reactants), which tells how many molecules of i are produced or consumed, we obtain an algebraic expression for the partial derivative
where we introduce a concise and historical name for this quantity, the "affinity", symbolized by A, as introduced by Théophile de Donder in 1923.(De Donder; Progogine & Defay, p. 69; Guggenheim, pp. 37, 240) The minus sign ensures that in a spontaneous change, when the change in the Gibbs free energy of the process is negative, the chemical species have a positive affinity for each other. The differential of G takes on a simple form that displays its dependence on composition change
If there are a number of chemical reactions going on simultaneously, as is usually the case,
with a set of reaction coordinates { ξj }, avoiding the notion that the amounts of the components ( Ni ) can be changed independently. The expressions above are equal to zero at thermodynamic equilibrium, while they are negative when chemical reactions proceed at a finite rate, producing entropy. This can be made even more explicit by introducing the reaction rates dξj/dt. For every physically independent process (Prigogine & Defay, p. 38; Prigogine, p. 24)
This is a remarkable result since the chemical potentials are intensive system variables, depending only on the local molecular milieu. They cannot "know" whether temperature and pressure (or any other system variables) are going to be held constant over time. It is a purely local criterion and must hold regardless of any such constraints. Of course, it could have been obtained by taking partial derivatives of any of the other fundamental state functions, but nonetheless is a general criterion for (−T times) the entropy production from that spontaneous process; or at least any part of it that is not captured as external work. (See Constraints below.)
We now relax the requirement of a homogeneous "bulk" system by letting the chemical potentials and the affinity apply to any locality in which a chemical reaction (or any other process) is occurring. By accounting for the entropy production due to irreversible processes, the equality for dG is now replaced by
or
Any decrease in the Gibbs function of a system is the upper limit for any isothermal, isobaric work that can be captured in the surroundings, or it may simply be dissipated, appearing as T times a corresponding increase in the entropy of the system and its surrounding. Or it may go partly toward doing external work and partly toward creating entropy. The important point is that the extent of reaction for a chemical reaction may be coupled to the displacement of some external mechanical or electrical quantity in such a way that one can advance only if the other also does. The coupling may occasionally be rigid, but it is often flexible and variable.
In solution chemistry and biochemistry, the Gibbs free energy decrease (∂G/∂ξ, in molar units, denoted cryptically by ΔG) is commonly used as a surrogate for (−T times) the global entropy produced by spontaneous chemical reactions in situations where no work is being done; or at least no "useful" work; i.e., other than perhaps ± P dV. The assertion that all spontaneous reactions have a negative ΔG is merely a restatement of the second law of thermodynamics, giving it the physical dimensions of energy and somewhat obscuring its significance in terms of entropy. When no useful work is being done, it would be less misleading to use the Legendre transforms of the entropy appropriate for constant T, or for constant T and P, the Massieu functions −F/T and −G/T, respectively.
Generally the systems treated with the conventional chemical thermodynamics are either at equilibrium or near equilibrium. Ilya Prigogine developed the thermodynamic treatment of open systems that are far from equilibrium. In doing so he has discovered phenomena and structures of completely new and completely unexpected types. His generalized, nonlinear and irreversible thermodynamics has found surprising applications in a wide variety of fields.
The non-equilibrium thermodynamics has been applied for explaining how ordered structures e.g. the biological systems, can develop from disorder. Even if Onsager's relations are utilized, the classical principles of equilibrium in thermodynamics still show that linear systems close to equilibrium always develop into states of disorder which are stable to perturbations and cannot explain the occurrence of ordered structures.
Prigogine called these systems dissipative systems, because they are formed and maintained by the dissipative processes which take place because of the exchange of energy between the system and its environment and because they disappear if that exchange ceases. They may be said to live in symbiosis with their environment.
The method which Prigogine used to study the stability of the dissipative structures to perturbations is of very great general interest. It makes it possible to study the most varied problems, such as city traffic problems, the stability of insect communities, the development of ordered biological structures and the growth of cancer cells to mention but a few examples.
In this regard, it is crucial to understand the role of walls and other constraints, and the distinction between independent processes and coupling. Contrary to the clear implications of many reference sources, the previous analysis is not restricted to homogeneous, isotropic bulk systems which can deliver only PdV work to the outside world, but applies even to the most structured systems. There are complex systems with many chemical "reactions" going on at the same time, some of which are really only parts of the same, overall process. An independent process is one that could proceed even if all others were unaccountably stopped in their tracks. Understanding this is perhaps a "thought experiment" in chemical kinetics, but actual examples exist.
A gas-phase reaction at constant temperature and pressure which results in an increase in the number of molecules will lead to an increase in volume. Inside a cylinder closed with a piston, it can proceed only by doing work on the piston. The extent variable for the reaction can increase only if the piston moves out, and conversely if the piston is pushed inward, the reaction is driven backwards.
Similarly, a redox reaction might occur in an electrochemical cell with the passage of current through a wire connecting the electrodes. The half-cell reactions at the electrodes are constrained if no current is allowed to flow. The current might be dissipated as Joule heating, or it might in turn run an electrical device like a motor doing mechanical work. An automobile lead-acid battery can be recharged, driving the chemical reaction backwards. In this case as well, the reaction is not an independent process. Some, perhaps most, of the Gibbs free energy of reaction may be delivered as external work.
The hydrolysis of ATP to ADP and phosphate can drive the force-times-distance work delivered by living muscles, and synthesis of ATP is in turn driven by a redox chain in mitochondria and chloroplasts, which involves the transport of ions across the membranes of these cellular organelles. The coupling of processes here, and in the previous examples, is often not complete. Gas can leak slowly past a piston, just as it can slowly leak out of a rubber balloon. Some reaction may occur in a battery even if no external current is flowing. There is usually a coupling coefficient, which may depend on relative rates, which determines what percentage of the driving free energy is turned into external work, or captured as "chemical work", a misnomer for the free energy of another chemical process. | [

There are complex systems with many chemical \"reactions\" going on at the same time, some of which are really only parts of the same, overall process. An independent process is one that could proceed even if all others were unaccountably stopped in their tracks.

] | Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Chemical thermodynamics involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the study of chemical questions and the spontaneity of processes. The structure of chemical thermodynamics is based on the first two laws of thermodynamics. Starting from the first and second laws of thermodynamics, four equations called the "fundamental equations of Gibbs" can be derived. From these four, a multitude of equations, relating the thermodynamic properties of the thermodynamic system can be derived using relatively simple mathematics. This outlines the mathematical framework of chemical thermodynamics. | 2002-02-25T15:51:15Z | 2023-11-03T18:35:07Z | [

5,938 | Standard works | The Standard Works of the Church of Jesus Christ of Latter-day Saints (LDS Church, the largest in the Latter Day Saint movement) are the four books that currently constitute its open scriptural canon. The four books of the standard works are:
The Standard Works are printed and distributed by the LDS Church both in a single binding called a quadruple combination and as a set of two books, with the Bible in one binding, and the other three books in a second binding called a triple combination. Current editions of the Standard Works include a number of non-canonical study aids, including a Bible dictionary, photographs, maps and gazetteer, topical guide, index, footnotes, cross references, and excerpts from the Joseph Smith Translation of the Bible.
The scriptural canon is "open" due to the Latter-day Saint belief in continuous revelation. Additions can be made to the scriptural canon with the "common consent" of the church's membership. Other branches of the Latter Day Saint movement reject some of the Standard Works or add other scriptures, such as the Book of the Law of the Lord and The Word of the Lord Brought to Mankind by an Angel.
Canons of various Latter Day Saint denominations reject some of the Standard Works canonized by the LDS Church or have included additional works. For instance, the Bickertonite sect does not consider the Pearl of Great Price or Doctrine and Covenants to be scriptural. Rather, they believe that the New Testament scriptures contain a true description of the church as established by Jesus Christ, and that both the King James Version of the Bible and the Book of Mormon are the inspired word of God. Some Latter Day Saint denominations accept earlier versions of the Standard Works or work to develop corrected translations. Others have purportedly received additional revelations.
The Community of Christ points to Jesus Christ as the living Word of God, and it affirms the Bible, along with the Book of Mormon, as well as its own regularly appended version of Doctrines and Covenants as scripture for the church. While it publishes a version of the Joseph Smith Translation of the Bible—which includes material from the Book of Moses—the Community of Christ also accepts the use of other English translations of the Bible, such as the standard King James Version and the New Revised Standard Version.
Like the aforementioned Bickertonites, the Church of Christ (Temple Lot) rejects the Doctrine and Covenants and the Pearl of Great Price, as well as the Joseph Smith Translation of the Bible, preferring to use only the King James Bible and the Book of Mormon as doctrinal standards. The Book of Commandments is accepted as being superior to the Doctrine and Covenants as a compendium of Joseph Smith's early revelations, but is not accorded the same status as the Bible or the Book of Mormon.
The Word of the Lord and The Word of the Lord Brought to Mankind by an Angel are two related books considered to be scriptural by Fettingite factions that separated from the Temple Lot church. Both books contain revelations allegedly given to former Church of Christ (Temple Lot) Apostle Otto Fetting by an angelic being who claimed to be John the Baptist. The latter title (120 messages) contains the entirety of the former's material (30 msgs.) with additional revelations (90 msgs.) purportedly given to William A. Draves by this same being, after Fetting's death. Neither are accepted by the larger Temple Lot body of believers.
The Church of Jesus Christ of Latter Day Saints (Strangite) considers the Bible (when correctly translated), the Book of Mormon, and editions of the Doctrine and Covenants published prior to Joseph Smith's death (which contained the Lectures on Faith) to be inspired scripture. They also hold the Joseph Smith Translation of the Bible to be inspired, but do not believe modern publications of the text are accurate. Other portions of The Pearl of Great Price, however, are not considered to be scriptural—though are not necessarily fully rejected either. The Book of Jasher was consistently used by both Joseph Smith and James Strang, but as with other Latter Day Saint denominations and sects, there is no official stance on its authenticity, and it is not considered canonical. This sect likewise holds as scriptural several prophecies, visions, revelations, and translations printed by James Strang, and published in the Revelations of James J. Strang.
An additional work called The Book of the Law of the Lord is also accepted as inspired scripture by the Strangites. They likewise hold as scriptural several prophecies, visions, revelations, and translations printed by James Strang, and published in the Revelations of James J. Strang. Among other things, this text contains his purported "Letter of Appointment" from Joseph Smith and his translation of the Voree plates.
The Church of Jesus Christ (Cutlerite) accepts the following as scripture: the Inspired Version of the Bible (including the Book of Moses and Joseph Smith–Matthew), the Book of Mormon, and the 1844 edition of the Doctrine and Covenants (including the Lectures on Faith). However, the revelation on tithing (section 107 in the 1844 edition; 119 in modern LDS editions) is emphatically rejected by members of this church, as it is not believed to be given by Joseph Smith. The Book of Abraham is rejected as scripture, as are the other portions of the Pearl of Great Price that do not appear in the Inspired Version of the Bible.
Many Latter Day Saint denominations have also either adopted the Articles of Faith or at least view them as a statement of basic theology. (They are considered scriptural by the larger LDS church and are included in The Pearl of Great Price.) At times, the Articles have been adapted to fit the respective belief systems of various faith communities.
Under the LDS Church's doctrine of continuing revelation, Latter-day Saints believe in the principle of revelation from God to his children. Individual members are entitled to divine revelation for confirmation of truths, gaining knowledge or wisdom, meeting personal challenges, and so forth. Parents are entitled to revelation for raising their families.
Church members believe that divine revelation for the direction of the entire church comes from God to the President of the Church, who they consider to be a prophet in the same sense as Noah, Abraham, Moses, Peter, and other biblical leaders. When other members of the First Presidency or Quorum of the Twelve speak as "moved upon by the Holy Ghost", it "shall be scripture, shall be the will of the Lord, shall be the mind of the Lord, shall be the word of the Lord, shall be the voice of the Lord, and the power of God unto salvation." Members are encouraged to ponder these revelations and pray to determine for themselves the truthfulness of doctrine.
The D&C teaches that "all things must be done in order, and by common consent in the church". This applies to adding new scripture. LDS Church president Harold B. Lee taught "The only one authorized to bring forth any new doctrine is the President of the Church, who, when he does, will declare it as revelation from God, and it will be so accepted by the Council of the Twelve and sustained by the body of the Church." There are several instances of this happening in the LDS Church:
When a doctrine undergoes this procedure, the LDS Church treats it as the word of God, and it is used as a standard to compare other doctrines. Lee taught:
It is not to be thought that every word spoken by the General Authorities is inspired, or that they are moved upon by the Holy Ghost in everything they speak and write. Now you keep that in mind. I don't care what his position is, if he writes something or speaks something that goes beyond anything that you can find in the standard works, unless that one be the prophet, seer, and revelator—please note that one exception—you may immediately say, "Well, that is his own idea!" And if he says something that contradicts what is found in the standard works (I think that is why we call them "standard"—it is the standard measure of all that men teach), you may know by that same token that it is false; regardless of the position of the man who says it.
English-speaking Latter-day Saints typically study a custom edition of the King James Version of the Bible (KJV), which includes custom chapter headings, footnotes referencing books in the Standard Works, and select passages from the Joseph Smith Translation of the Bible.
Though the KJV was always commonly used, it was officially adopted in the 1950s when J. Reuben Clark, of the church's First Presidency, argued extensively that newer translations, such as Revised Standard Version of 1952, were of lower quality and less compatible with LDS tradition. After publishing its own KJV edition in 1979, the First Presidency announced in 1992 that the KJV was the church's official English Bible, stating "[w]hile other Bible versions may be easier to read than the King James Version, in doctrinal matters latter-day revelation supports the King James Version in preference to other English translations." In 2010 this was written into the church's Handbook, which directs official church policy and programs.
A Spanish version, with a similar format and using a slightly revised version of the 1909 Reina-Valera translation, was published in 2009. Latter-day Saints in other non-English speaking areas may use other versions of the Bible.
Though the Bible is part of the LDS canon and members believe it to be the word of God, they believe that omissions and mistranslations are present in even the earliest known manuscripts. They claim that the errors in the Bible have led to incorrect interpretations of certain passages. Thus, as church founder Joseph Smith explained, the church believes the Bible to be the word of God "as far as it is translated correctly". The church teaches that "[t]he most reliable way to measure the accuracy of any biblical passage is not by comparing different texts, but by comparison with the Book of Mormon and modern-day revelations".
The manuscripts of the Joseph Smith Translation of the Bible state that "the Songs of Solomon are not inspired scripture," and therefore it is not included in LDS canon and rarely studied by members of the LDS Church. However, it is still printed in every version of the King James Bible published by the church.
Although the Apocrypha was part of the 1611 edition of the KJV, the LDS Church does not currently use the Apocrypha as part of its canon. Joseph Smith taught that while the contemporary edition of the Apocrypha was not to be relied on for doctrine, it was potentially useful when read with a spirit of discernment.
Joseph Smith translated selected verses of the Bible, working by subject. His complete work is known as the Joseph Smith Translation of the Bible, or the Inspired Version. Although this selected translation is not generally quoted by church members, the English Bible issued by the church and commonly used by Latter-day Saints contains cross-references to the Joseph Smith Translation (JST), as well as an appendix containing longer excerpts from it. Excerpts that were too long to include in the Bible appendix are included in the Pearl of Great Price as the Book of Moses (for Genesis 1:1-6:13) and Joseph Smith-Matthew (for Matthew 23:39-24:51 and Mark 13).
Latter-day Saints consider the Book of Mormon a volume of holy scripture comparable to the Bible. It contains a record of God's dealings with the prophets and ancient inhabitants of the Americas. The introduction to the book asserts that it "contains, as does the Bible, the fullness of the everlasting gospel. The book was written by many ancient prophets by the spirit of prophecy and revelation. Their words, written on gold plates, were quoted and abridged by a prophet-historian named Mormon."
Segments of the Book of Mormon provide an account of the culture, religious teachings, and civilizations of some of the groups who immigrated to the New World. One came from Jerusalem in 600 B.C., and afterward separated into two nations, identified in the book as the Nephites and the Lamanites. Some years after their arrival, the Nephites met with a similar group, the Mulekites who left the Middle East during the same period. An older group arrived in America much earlier, when the Lord confounded the tongues at the Tower of Babel. This group is known as the Jaredites and their story is condensed in the Book of Ether. The crowning event recorded in the Book of Mormon is the personal ministry of Jesus Christ among Nephites soon after his resurrection. This account presents the doctrines of the gospel, outlines the plan of salvation, and offers men peace in this life and eternal salvation in the life to come. The latter segments of the Book of Mormon detail the destruction of these civilizations, as all were destroyed except the Lamanites. The book asserts that the Lamanites are among the ancestors of the indigenous peoples of the Americas.
According to his record, Joseph Smith translated the Book of Mormon by gift and power of God through a set of interpreters later referred to as the Urim and Thummim. Eleven witnesses signed testimonies of its authenticity, which are now included in the preface to the Book of Mormon. The Three Witnesses testified to have seen an angel present the gold plates and to have heard God bear witness to its truth. Eight others stated that Joseph Smith showed them the plates and that they handled and examined them.
The church's D&C is a collection of revelations, policies, letters, and statements given to the modern church by past church presidents. This record contains points of church doctrine and direction on church government. The book has existed in numerous forms, with varying content, throughout the history of the church and has also been published in differing formats by the various Latter Day Saint denominations. When the church chooses to canonize new material, it is typically added to the Doctrine and Covenants; the most recent changes were made in 1981.
The Pearl of Great Price is a selection of material produced by Joseph Smith and deals with many significant aspects of the faith and doctrine of the church. Many of these materials were initially published in church periodicals in the early days of the church.
The Pearl of Great Price contains five sections:
Historically, in the church's Sunday School and Church Educational System (CES) classes, the standard works have been studied and taught in a four-year rotation:
However, church leaders have emphasized that members should not restrict their study of the standard works to the particular book being currently studied in Sunday School or other religious courses. Specifically, church president Ezra Taft Benson taught:
At present, the Book of Mormon is studied in our Sunday School and seminary classes every fourth year. This four-year pattern, however, must not be followed by Church members in their personal and family study. We need to read daily from the pages of [that] book ....
In November 2014, the church announced changes in the curriculum to be used within CES, including the church's four institutions of higher education, such as Brigham Young University. The church's seminary program will retain the current four-year rotation of study. Beginning in the fall of 2015, incoming institute of religion and CES higher education students will be required to take four new cornerstone courses:
The church's intent is to further integrate the teachings found in the Standard Works with that of church leaders and other current sources.
All the denominations in the Latter Day Saint movement listed below use the same canon of the Book of Mormon. Other uses and content vary among their respective canons. | [

] | The Standard Works of the Church of Jesus Christ of Latter-day Saints are the four books that currently constitute its open scriptural canon. The four books of the standard works are: The Authorized King James Version as the official scriptural text of the Bible
The Book of Mormon, subtitled since 1981 "Another Testament of Jesus Christ"
The Doctrine and Covenants (D&C)
The Pearl of Great Price The Standard Works are printed and distributed by the LDS Church both in a single binding called a quadruple combination and as a set of two books, with the Bible in one binding, and the other three books in a second binding called a triple combination. Current editions of the Standard Works include a number of non-canonical study aids, including a Bible dictionary, photographs, maps and gazetteer, topical guide, index, footnotes, cross references, and excerpts from the Joseph Smith Translation of the Bible. The scriptural canon is "open" due to the Latter-day Saint belief in continuous revelation. Additions can be made to the scriptural canon with the "common consent" of the church's membership. Other branches of the Latter Day Saint movement reject some of the Standard Works or add other scriptures, such as the Book of the Law of the Lord and The Word of the Lord Brought to Mankind by an Angel. | 2001-07-27T17:31:42Z | 2023-12-31T06:46:46Z | [

5,942 | History of the Church of Jesus Christ of Latter-day Saints | The history of the Church of Jesus Christ of Latter-day Saints (LDS Church) has three main periods, described generally as:
The LDS Church originated in the burned-over district within Western New York. Joseph Smith, the founder of the Latter Day Saint movement, was raised in this region during the Second Great Awakening. Smith gained a small following in the late 1820s as he was dictating the Book of Mormon, which he said was a translation of inscriptions found on a set of golden plates buried near his home in Upstate New York by an Indigenous American prophet named Moroni.
On April 6, 1830, at the home of Peter Whitmer in Fayette, New York, Smith organized the religion's first legal church entity, the Church of Christ. The church rapidly gained a following who viewed Smith as their prophet. The main body of the church moved first to Kirtland, Ohio, in the early 1830s, then to Missouri in 1838, where the 1838 Mormon War with other Missouri settlers ensued. On October 27, 1838, Lilburn W. Boggs, the Governor of Missouri, signed Missouri Executive Order 44, which called to expel adherents from the state. Approximately 15,000 Mormons fled to Illinois after their surrender at Far West on November 1, 1838.
After fleeing from Missouri, Smith founded the city of Nauvoo, Illinois, which grew rapidly. When Smith was killed, Nauvoo had a population of about 12,000 people, nearly all members of Smith's church. After his death, a succession crisis ensued and the majority voted to accept the Quorum of the Twelve, led by Brigham Young, as the church's leading body.
After suffering persecution in Illinois, Young left Nauvoo in 1846 and led his followers, the Mormon pioneers, to Salt Lake Valley. The Mormon pioneers then branched out to pioneer a large state called Deseret, establishing colonies that spanned from Canada to Mexico.
Young incorporated the LDS Church as a legal entity and governed his followers as a theocratic leader, assuming both political and religious positions. He also publicized the previously secret practice of plural marriage, a form of polygamy. By 1857, tensions had again escalated between Latter-day Saints and other Americans, largely as a result of the teachings on polygamy and theocracy. During the Utah War, from 1857 to 1858, the United States Army conducted an invasion of Utah, after which Young agreed to be replaced by a non-Mormon territorial Governor, Alfred Cumming.
The church, however, still wielded significant political power in Utah Territory. Even after Young died in 1877, many members continued the practice of polygamy despite opposition by the United States Congress. When tensions with the U.S. government came to a head in 1890, the church officially abandoned the public practice of polygamy in the United States and eventually stopped performing official polygamous marriages altogether after a Second Manifesto in 1904. Eventually, the church adopted a policy of excommunicating members who were found to be practicing polygamy, and today seeks to actively distance itself from polygamist fundamentalist groups.
During the 20th century, the church became an international organization. The church first began engaging with mainstream American culture, and then with international cultures. It engaged especially in Latin American countries by sending out thousands of missionaries. The church began publicly supporting monogamy and the nuclear family, and at times played a role in political matters. One of the official changes to the organization during the modern era was the participation of black members in temple ceremonies, which began in 1978, reversing a policy originally instituted by Young. The church has also gradually changed its temple ceremony. There continue to be periodic changes in the structure and organization of the church.
Joseph Smith, founder of the Latter Day Saint movement, was raised in this region during the Second Great Awakening. Smith gained a small following in the late 1820s as he was dictating the Book of Mormon. He stated that the book was a translation of characters from an ancient script called reformed Egyptian that he stated was inscribed on gold plates which had been buried near his residence in western New York by an indigenous American prophet. Smith said he had been given the plates from the angel Moroni.
On April 6, 1830, in western New York, Smith organized the religion's first legal church entity, the Church of Christ. The church rapidly gained a following who viewed Smith as their prophet. In late 1830, Smith envisioned a "City of Zion", a utopian city in Native American lands near Independence, Missouri. In October 1830, he sent his Assistant President, Oliver Cowdery, and others on a mission to the area. Passing through Kirtland, Ohio, the missionaries converted a congregation of Disciples of Christ led by Sidney Rigdon, and in 1831, Smith decided to temporarily move his followers to Kirtland until lands in the Missouri area could be purchased. In the meantime, the church's headquarters remained in Kirtland from 1831 to 1838 and there the church built its first temple and continued to grow in membership from 680 to 17,881 members.
While the main church body was in Kirtland, many of Smith's followers attempted to establish settlements in Missouri but were met with resistance from other Missourians who believed Mormons were abolitionists or who distrusted their political ambitions. After Smith and other Mormons in Kirtland emigrated to Missouri in 1838, hostilities escalated into the 1838 Mormon War, culminating in adherents being expelled from the state under an Extermination Order signed by Lilburn W. Boggs, the governor of Missouri.
After Missouri, Smith founded the city of Nauvoo, Illinois as the new church headquarters, and served as the city's mayor and leader of the Nauvoo Legion. As church leader, Smith also instituted the then-secret practice of plural marriage and taught a political system he called "theodemocracy", to be led by a Council of Fifty which had secretly and symbolically anointed him king of this millennial theodemocracy.
On June 7, 1844, a newspaper called the Nauvoo Expositor, edited by dissident Mormon William Law, issued a scathing criticism of polygamy and the Nauvoo theocratic government, including a call for church reform based on earlier Mormon principles. In response to the newspaper's publication, Smith and the Nauvoo City Council declared the paper a public nuisance, and ordered the press destroyed. The town marshal carried out the order during the evening of June 10. The destruction of the press led to charges of riot against Smith and other members of the council. After Smith surrendered on the charges, he was also charged with treason against Illinois. While in state custody, he and his brother Hyrum Smith, who was second in line to the church presidency, were killed in a firefight with an angry mob attacking the jail on June 27, 1844.
After Smith's death, a succession crisis ensued. In this crisis a number of church leaders campaigned to lead the church. Most adherents voted on August 8, 1844, to accept the leadership of Brigham Young, the senior apostle. Later, adherents bolstered their succession claims by referring to a March 1844 meeting in which Joseph committed the "keys of the kingdom" to a group of members within the Council of Fifty that included the apostles. In addition, by the end of the 1800s, several of Young's followers had published reminiscences recalling that during Young's August 8 speech, he looked or sounded similar to Joseph Smith, which they attributed to the power of God.
Under the leadership of Brigham Young, church leaders planned to leave Nauvoo, Illinois in April 1846, but amid threats from the state militia, they were forced to cross the Mississippi River in the cold of February. They eventually left the boundaries of the United States to what is now Utah, where they founded Salt Lake City.
The groups that left Illinois for Utah became known as the Mormon pioneers and forged a path to Salt Lake City known as the Mormon Trail. The arrival of the Mormon Pioneers in the Salt Lake Valley on July 24, 1847, is commemorated by the Utah State holiday Pioneer Day.
Groups of converts from the United States, Canada, Europe, and elsewhere were encouraged to gather in Utah in the following decades. Both the original Mormon migration and subsequent convert migrations resulted in many deaths. Brigham Young organized a great colonization of the American West, with Mormon settlements extending from Canada to Mexico. Notable cities that sprang from early Mormon settlements include San Bernardino, California, Las Vegas, Nevada, and Mesa, Arizona.
Following the death of Joseph Smith, Brigham Young stated that the church should be led by the Quorum of the Twelve Apostles (see succession crisis). Later, after the migration to Utah had begun, Young was sustained as a member of the First Presidency on December 25, 1847, and then as President of the Church on October 8, 1848.
In the 1848 Treaty of Guadalupe Hidalgo, Mexico ceded the area to the United States. As a result, Brigham Young sent emissaries to Washington, D.C. with a proposal to create a vast State of Deseret, of which Young would be the first governor. Instead, Congress created the much smaller Utah Territory in 1850, and Young was appointed governor in 1851. Because of his religious position, Young exercised much more practical control over the affairs of Mormon and non-Mormon settlers than a typical territorial governor of the time.
For most of the 19th century, the LDS Church maintained an ecclesiastical court system parallel to federal courts, and required Mormons to use the system exclusively for civil matters, or face church discipline.
In 1856–1858, the church underwent what is commonly called the Mormon Reformation. In 1855, a drought struck the flourishing territory. Very little rain fell, and dependable mountain streams ran very low. An infestation of grasshoppers and crickets destroyed whatever crops the Mormons had managed to salvage. During the winter of 1855–56, flour and other basic necessities were very scarce and costly.
In September 1856, as the drought continued, the trials and difficulties led to an explosion of religious fervor. Jedediah M. Grant, a counselor in the First Presidency and a well-known conservative voice in the extended community, preached three days of fiery sermons to the people of Kaysville, Utah territory. He called for repentance and a general recommitment to moral living and religious teachings. 500 people presented themselves for "re-baptism" — a symbol of their determination to reform their lives. The message spread from Kaysville to surrounding Mormon communities. Church leaders traveled around the territory, expressing their concern about signs of spiritual decay and calling for repentance. Members were asked to seal their rededication with re-baptism.
Several sermons Willard Richards and George A. Smith had given earlier in the history of the church had touched on the concept of blood atonement, suggesting that apostates could become so enveloped in sin that the voluntary shedding of their own blood might increase their chances of eternal salvation. On September 21, 1856, while calling for sincere repentance, Brigham Young took the idea further, and stated:
I know that there are transgressors, who, if they knew themselves and the only condition upon which they can obtain forgiveness, would beg of their brethren to shed their blood, that the smoke might ascend to God as an offering to appease the wrath that is kindled against them, and that the law might have its course. Journal of Discourses 4:43.
This belief became ingrained in the church's public image during that period and drew widespread ridicule in Eastern newspapers, particularly in connection with the practice of polygamy. The notion faced consistent criticism from numerous Mormons and was ultimately disavowed as an official doctrine by the LDS Church in 1978. Nevertheless, in contemporary times, critics of the church and some popular writers continue to associate a formal doctrine of blood atonement with the Church.
Throughout the winter, special meetings were held and Mormons were urged to adhere to the commandments of God and the practices and precepts of the church. Preaching placed emphasis on the practice of plural marriage, adherence to the Word of Wisdom, attendance at church meetings, and personal prayer. On December 30, 1856, the entire all-Mormon territorial legislature was re-baptized for the remission of their sins, and confirmed under the hands of the Twelve Apostles. As time went on, however, the sermons became intolerant and hysterical.
In 1857–1858, the church was involved in an armed conflict with the U.S. government, now known as the Utah War. The settlers and the United States government battled for hegemony over the culture and government of the territory. Tensions over the Utah War, the murder of Mormon apostle Parley P. Pratt in Arkansas, and threats of violence from the Baker-Fancher wagon train (and possibly other factors), resulted in rogue Mormon settlers in southern Utah massacring a wagon train from Arkansas, known as Mountain Meadows massacre. The result of the Utah War was the succeeding of the governorship of the Utah territory from Brigham Young to Alfred Cumming, an outsider appointed by President James Buchanan.
The church had attempted unsuccessfully to institute the United Order numerous times, most recently during the Mormon Reformation. In 1874, Young once again attempted to establish a permanent Order, which he now called the "United Order of Enoch" in at least 200 Mormon communities, beginning in St. George, Utah on February 9, 1874.
In Young's Order, producers typically transferred ownership of their property to the Order itself. All members within the order would then collectively partake in the cooperative's net income, often distributed in proportion to the value of the property initially contributed. Occasionally, members received wages for their labor on the shared property. Much like Joseph Smith's United Order, Young's Order had a brief existence. By the time Young passed away in 1877, most of these United Orders had faltered. As the 19th century drew to a close, these Orders had effectively become extinct.
Brigham Young died in August 1877. After his death, the First Presidency was not reorganized until 1880, when Young was succeeded by John Taylor, who in the interim had served as President of the Quorum of the Twelve Apostles.
For several decades, polygamy was preached as God's law. Brigham Young, the church’s second president, had 56 wives during his life; many other church leaders were also polygamists.
This early practice of polygamy caused conflict between church members and the broader American society. In 1854, the Republican party referred in its platform to polygamy and slavery as the "twin relics of barbarism." In 1862, the U.S. Congress enacted the Morrill Anti-Bigamy Act, signed by Abraham Lincoln, which made bigamy a felony in the territories punishable by $500 or five years in prison. The law also permitted the confiscation of church property without compensation. However, this law was not enforced by the Lincoln administration or by Mormon-controlled territorial probate courts. Moreover, as Mormon polygamist marriages were performed in secret, it was difficult to prove when a polygamist marriage had taken place. In the meantime, Congress was preoccupied with the American Civil War.
In 1874, after the war, Congress passed the Poland Act, which transferred jurisdiction over Morrill Act cases to federal prosecutors and courts, which were not controlled by Mormons. In addition, the Morrill Act was upheld in 1878 by the United States Supreme Court in the case of Reynolds v. United States. After Reynolds, Congress became even more aggressive against polygamy, and passed the Edmunds Act in 1882. The Edmunds Act prohibited not just bigamy, which remained a felony, but also bigamous cohabitation, which was prosecuted as a misdemeanor, and did not require proof an actual marriage ceremony had taken place. The Act also vacated the Utah territorial government, created an independent committee to oversee elections to prevent Mormon influence, and disenfranchised any former or present polygamist. Further, the law allowed the government to deny civil rights to polygamists without a trial.
In 1887, Congress passed the Edmunds-Tucker Act, which allowed prosecutors to force plural wives to testify against their husbands, abolished the right of women to vote, disincorporated the church, and confiscated the church's property. By this time, many church leaders had gone into hiding to avoid prosecution, and half the Utah prison population was composed of polygamists.
Church leadership officially ended the practice in the United States in 1890, based on a decree of church president Wilford Woodruff called the 1890 Manifesto.
The church's modern era began soon after it renounced polygamy in 1890. Prior to the 1890 Manifesto, church leaders had been in hiding, many ecclesiastical matters had been neglected, and the church organization itself had been disincorporated. With the reduction in federal pressure afforded by the Manifesto, however, the church began to re-establish its institutions.
The 1890 Manifesto did not, itself, eliminate the practice of new plural marriages, as they continued to occur clandestinely, mostly with church approval and authority. In addition, most Mormon polygamists and every polygamous general authority continued to cohabit with their polygamous wives. Mormon leaders, including Woodruff, maintained that the Manifesto was a temporary expediency designed to enable Utah to obtain statehood and that at some future date, the practice would soon resume. Nevertheless, the 1890 Manifesto provided the church breathing room to obtain Utah's statehood, which it received in 1896 after a campaign to convince the American public that Mormon leaders had abandoned polygamy and intended to stay out of politics.
Despite being admitted to the United States, Utah was initially unsuccessful in having its elected representatives and senators seated in the United States Congress. In 1898, Utah elected general authority B.H. Roberts to the United States House of Representatives as a Democrat. Roberts, however, was denied a seat there because he was practicing polygamy. In 1903, the Utah legislature selected Reed Smoot, also an LDS Church general authority but also a monogamist, as its first senator. From 1904 to 1907, the United States Senate conducted a series of Congressional hearings on whether Smoot should be seated. Eventually, the Senate granted Smoot a seat and allowed him to vote. However, the hearings raised controversy as to whether polygamy had actually been abandoned as claimed in the 1890 Manifesto, and whether the LDS Church continued to exercise influence on Utah politics. In response to these hearings, church president Joseph F. Smith issued a Second Manifesto denying that any post-Manifesto marriages had the church's sanction, and announcing that those entering such marriages in the future would be excommunicated.
The Second Manifesto did not annul existing plural marriages within the church, and the church tolerated some degree of polygamy into at least the 1930s. However, eventually, the church adopted a policy of excommunicating its members found practicing polygamy and today seeks to actively distance itself from Mormon fundamentalist groups still practicing polygamy. In modern times, members of the Mormon religion do not practice polygamy.
In 1870, the Utah Territory had become one of the first polities to grant women the right to vote—a right which the U.S. Congress revoked in 1887 as part of the Edmunds-Tucker Act.
As a result, a number of LDS women became active and vocal proponents of women's rights. Of particular note was the LDS journalist and suffragist Emmeline B. Wells, editor of the Woman's Exponent, a Utah feminist newspaper. Wells, who was both a feminist and a polygamist, wrote vocally in favor of a woman's role in the political process and public discourse. National suffrage leaders, however, were somewhat perplexed by the seeming paradox between Utah's progressive stand on women's rights, and the church's stand on polygamy.
In 1890, after the church officially renounced polygamy, U.S. suffrage leaders began to embrace Utah's feminism more directly, and in 1891, Utah hosted the Rocky Mountain Suffrage Conference in Salt Lake City, attended by such national feminist leaders as Susan B. Anthony and Anna Howard Shaw. The Utah Woman Suffrage Association, which had been formed in 1889 as a branch of the American Woman Suffrage Association (which in 1890 became the National American Woman Suffrage Association), was then successful in demanding that the constitution of the nascent state of Utah should enfranchise women. In 1896, Utah became the third state in the U.S. to grant women the right to vote.
The LDS Church was actively involved in support of the temperance movement in the 19th century, and later the prohibition movement under the presidency of Heber J. Grant.
Mormonism has had a mixed relationship with socialism in its various forms. In the earliest days of Mormonism, Joseph Smith had established a form of Christian communalism, an idea made popular during the Second Great Awakening, combined with a move toward theocracy. Mormons referred to this form of theocratic communalism as the United Order, or the law of consecration. While short-lived during the life of Joseph Smith, the United Order was re-established for a time in several communities of Utah during the theocratic political leadership of Brigham Young. Some aspects of secular socialism also found a place in the political views of Joseph Smith. He ran for President of the United States on a platform that included a nationalized bank aimed at addressing the abuses of private banks.
As a secular political leader in Nauvoo, Joseph Smith introduced collective farms to support those lacking property, ensuring sustenance for the poor and their families. Upon reaching Utah, Brigham Young guided the church leadership in advocating for collective industry ownership. In 1876, a circular issued by them emphasized the importance of wealth distribution for liberty, warning against tyranny, oppression, and the vices arising from unequal wealth distribution. The circular, signed by the Quorum of the Twelve and the First Presidency, cautioned that continuous wealth concentration among the rich and deepening poverty among the poor could lead the nation toward disaster.
In addition to religious socialism, many Mormons in Utah were interested in the secular socialist movement that began in America during the 1890s. During the 1890s to the 1920s, the Utah Social Democratic Party, which became part of the Socialist Party of America in 1901, elected about 100 socialists to state offices in Utah. An estimated 40% of Utah Socialists were Mormon. Many early socialists visited the Church's cooperative communities in Utah with great interest and were well received by the church leadership. Prominent early socialists such as Albert Brisbane, Victor Prosper Considerant, Plotino Rhodakanaty, Edward Bellamy, and Ruth & Reginald Wright Kauffman showed great interest in the successful cooperative communities of the church in Utah. For example, while doing research for what would become a best selling socialist novel, Looking Backward, Edward Bellamy toured the Church's cooperative communities in Utah and visited with Lorenzo Snow for a week. Ruth & Reginald Wright Kauffman also wrote a book, though this one non-fiction, after visiting the Church in Utah. Their book was titled The Latter Day Saints: A Study of the Mormons in the Light of Economic Conditions, which discussed the Church from a Marxist perspective. Socialist Plotino Rhodakanaty also became a prominent early church member in Mexico, after being baptized by a group of missionaries which included Moses Thatcher. Thatcher kept in touch with Rhodakanaty for years following and was himself perhaps the most prominent member of the church to have openly identified himself as a socialist supporter.
Albert Brisbane and Victor Prosper Considerant also visited the church in Utah during its early years, prompting Considerant to note that "thanks to a certain dose of socialist solidarity, the Mormons have in a few years attained a state of unbelievable prosperity". Attributing the peculiar socialist attitudes of the early Mormons to their success in the desert of the western United States was common even among those who were not themselves socialist. For instance, in his book History of Utah, 1540–1886, Hubert Howe Bancroft points out that the Mormons "while not communists, the elements of socialism enter strongly into all their relations, public and private, social, commercial, and industrial, as well as religious and political. This tends to render them exclusive, independent of the gentiles and their government, and even in some respects antagonistic to them. They have assisted each other until nine out of ten own their farms, while commerce and manufacturing are to large extent cooperative. The rights of property are respected; but while a Mormon may sell his farm to a gentile, it would not be deemed good fellowship for him to do so."
While religious and secular socialism gained some acceptance among Mormons, the church was more circumspect about Marxist Communism because of its acceptance of violence as a means to achieve revolution. From the time of Joseph Smith, the church had taken a favorable view as to the American Revolution and the necessity at times to violently overthrow the government, however the church viewed the revolutionary nature of Leninist Communism as a threat to the United States Constitution, which the church saw as divinely inspired to ensure the agency of man. In 1936, the First Presidency issued a statement which stated in part that “to support Communism is treasonable to our free institutions, and no patriotic American citizen may become either a Communist or supporter of Communism. ... [N]o loyal American citizen and no faithful church member can be a Communist.” The strident atheism of Marxist thought may have also been considered incompatible with the church’s fundamentally religious worldview.
In later years, such leaders as Ezra Taft Benson would take a stronger anti-Communist position publicly, his anti-Communism often being anti-leftist in general. However, Benson's views often brought embarrassment to the church leadership, and when Benson was sent to Europe on a mission for the church, many believed this was a way of getting Benson out of the US where his right-wing views were a point of embarrassment for the church. While publicly claiming that this was not the reason for Benson's call to Europe, church president Joseph Fielding Smith wrote a letter to Congressman Ralph Harding stating that "It would be better for him and for the church and all concerned, if he would settle down to his present duties and let all political matters take their course. He is going to take a mission to Europe in the near future and by the time he returns I hope he will get all the political notions out of his system." In another letter written in response to questions about how long Benson would be on his mission to Europe from U.S. Under-Secretary of State Averell Harriman, the church's first counselor in the First Presidency, Hugh B. Brown, responded: "If I had my way, he'll never come back!". Later, Benson would become church president and backed off of his political rhetoric. Toward the end of his presidency, the church even began to discipline church members who had taken Benson's earlier hardline right-wing speeches too much to heart, some of whom claimed that the church had excommunicated them for adhering too closely to Benson's right-wing ideology.
Soon after the 1890 Manifesto, the LDS Church was in a dire financial condition. It was recovering from the U.S. crackdown on polygamy, and had difficulty reclaiming property that had been confiscated during polygamy raids. Meanwhile, there was a national recession beginning in 1893. By the late 1890s, the church was about $2 million in debt, and near bankruptcy. In response, Lorenzo Snow, then President of the Church, conducted a campaign to raise the payment of tithing, of which less than 20% of LDS had been paying during the 1890s. After a visit to Saint George, Utah, which had a much higher-than-average percentage of full 10% tithe-payers, Snow felt that he had received a revelation. As a result of Snow's vigorous campaign, tithing payment increased dramatically from 18.4% in 1898 to an eventual peak of 59.3% in 1910. From that time, payment of tithing has been a requirement for temple worship within the faith.
I pray that every man, woman and child who has means shall pay one-tenth of their income as tithing.
-Lorenzo Snow, 1899 General Conference
During this timeframe, changes were made in stipends for bishops and general authorities. Bishops once received a 10% stipend from tithing funds, but are now purely volunteer. General authorities receive stipends, and formerly received loans from church funds.
In earlier times, Latter-day Saint meetings occurred every Sunday morning and evening, with additional gatherings throughout the week. This structure was convenient for Utah Saints, as they typically resided within walking distance of a church building. However, outside of Utah, this meeting schedule presented logistical challenges. In 1980, the church implemented the "Consolidated Meeting Schedule," consolidating most church meetings into a three-hour block on Sundays.
In 2019, the meeting schedule was condensed into a two-hour block, with meetings during the second hour alternating between Sunday School and gendered (Relief Society / Priesthood) meetings.
In 1982, the First Presidency announced that the length of service of male full-time missionaries would be reduced to 18 months. In 1984, a little more than two years later, it was announced that the length of service would be returned to its original length of 24 months.
Starting in 1990, paying for a mission became easier on those called to work in industrialized nations. Missionaries began paying into a church-wide general missionary fund instead of paying on their own. The amount paid into the fund does not vary by location; therefore, missionaries serving in low-cost-of-living-areas effectively subsidize missionaries serving in areas with higher costs.
During the 1960s, the church pursued a Priesthood Correlation Program, which streamlined and centralized the structure of the church. It had begun earlier in 1908, as the Correlation Program. The program increased church control over viewpoints taught in local church meetings.
During this time period, priesthood editorial oversight was established of formerly priesthood-auxiliary-specific YMMIA, YLMIA, Relief Society, Primary, and Sunday School magazines.
In 1911, the church adopted the Scouting program for its male members of appropriate age.
The Priesthood-Auxiliary movement (1928–1937) re-emphasized the church hierarchy around Priesthood, and re-emphasized other church organizations as "priesthood auxiliaries" with reduced autonomy.
As the church began to collide and meld with cultures outside of Utah and the United States, the church began to jettison some of the parochialisms and prejudices that had become part of Latter-day Saint culture but were not essential to Mormonism. During and after the civil rights movement, the church faced a critical point in its history, where its previous attitudes toward other cultures and people of color, which had once been shared by much of the Anglo-American mainstream, carried racist and neocolonialist connotations. The mid-20th century saw the church critiqued over its positions on Black and Native American matters, especially the institution's bias towards European standards or norms at the expense and disregard of other racial or ethnic backgrounds' identity and humanity.
The cause of some of the church's most damaging publicity had to do with the church's policy of discrimination against black people. Black people were always officially welcome in the church, and Joseph Smith established an early precedent for it by ordaining black males to the Priesthood. Smith was also anti-slavery, going so far as to run on an anti-slavery platform as a candidate for the presidency of the United States. At times, however, Smith had shown sympathy for the belief that black people were the cursed descendants of Cain, a belief which was commonly held in his day. In 1849, church doctrine taught that while black people could be baptized, black men could not be ordained to the Priesthood and black people could not enter LDS temples. Journal histories and public teachings of the time reflect that Young and others stated that God would some day reverse this policy of discrimination.
By the late 1960s, the church had expanded into Brazil, the Caribbean, and the nations of Africa, but it was also being criticized for its policy of racial discrimination. In the case of Africa and the Caribbean, the church had not yet begun large-scale missionary efforts in most areas. There were large groups of people who desired to join the church in Ghana and Nigeria and there were also many faithful church members who were of African descent in Brazil. On June 9, 1978, under the administration of Spencer W. Kimball, the church's leadership changed the long-standing policy.
Today, there are many black members of the church, and there are also many predominantly black congregations. In the Salt Lake City area, black members have organized branches of an official church auxiliary which is called the Genesis Groups.
During the post-World War II period, the church also began to focus on expansion into a number of Native American cultures, as well as Oceanic cultures, which many Mormons considered to be the same ethnicity. These peoples were called "Lamanites", because they were all believed to descend from the Lamanite group in the Book of Mormon. In 1947, the church began the Indian Placement Program, where Native American students (upon request by their parents) were voluntarily placed in anglo Latter-day Saint foster homes during the school year, where they would attend public schools and become assimilated into Mormon culture.
In 1955, the church began ordaining black Melanesians to the Priesthood.
The church's policy toward Native Americans also came under fire during the 1970s. In particular the Indian Placement Program was criticized as neocolonial. In 1977, the U.S. government commissioned a study to investigate accusations that the church was using its influence to push children into joining the program. However, the commission rejected these accusations and found that the program was beneficial in many cases, and provided well-balanced American education for thousands, allowing the children to return to their cultures and customs. One issue was that the time away from family caused the assimilation of Native American students into American culture, rather than allowing the children to learn within, and preserve, their own culture. By the late 1980s, the program had been in decline, and in 1996, it was discontinued. In 2016, three lawsuits against the LDS Church were filed in the Navajo Nation District Court, alleging that participants in the program were sexually abused in their foster homes. The church asked for the lawsuits to be dismissed on jurisdictional grounds, arguing that the alleged abuse took place outside the reservation.
In 1981, the church published a new LDS edition of the Standard Works that changed a passage in The Book of Mormon that Lamanites (considered by many Latter-day Saints to be Native Americans) will "become white and delightsome" after accepting the gospel of Jesus Christ. Instead of continuing the original reference to skin color, the new edition replaced the word "white" with the word "pure".
In 1927, the church implemented its "Good Neighbor policy", whereby it removed any suggestion in church literature, sermons, and ordinances that its members should seek vengeance on US citizens or governments, particularly for the assassinations of its founder Joseph Smith and his brother, Hyrum. The church also reformed the temple ordinance around this time to remove such references.
The issue of evolution has been a point of controversy for some members of the church. The first official statement on the issue of evolution was in 1909, which marked the centennial of Charles Darwin's birth and the 50th anniversary of his masterwork, On the Origin of Species. On that year, the First Presidency led by Joseph F. Smith as president, issued a statement reinforcing the predominant religious view of creationism, and calling human evolution one of the "theories of men", but falling short of declaring evolution untrue or evil.
Soon after the 1909 statement, Joseph F. Smith professed in an editorial that "the church itself has no philosophy about the modus operandi employed by the Lord in His creation of the world."
In 1925, as a result of publicity from the "Scopes Monkey Trial" concerning the right to teach evolution in Tennessee public schools, the First Presidency reiterated its 1909 stance, stating that "The Church of Jesus Christ of Latter-day Saints, basing its belief on divine revelation, ancient and modern, declares man to be the direct and lineal offspring of Deity."
In the early 1930s there was an intense debate between liberal theologian and general authority B. H. Roberts and some members of the Council of the Twelve Apostles over attempts by B. H. Roberts to reconcile the fossil record with the scriptures by introducing a doctrine of pre-Adamite creation, and backing up this speculative doctrine using geology, biology, anthropology, and archeology. More conservative members of the Twelve Apostles, including Joseph Fielding Smith, rejected his speculation because it contradicted the idea that there was no death until after the fall of Adam. James E. Talmage published a book through the LDS Church that explicitly stated that organisms lived and died on this earth before the earth was fit for human habitation.
The debate over pre-Adamites has been interpreted by LDS proponents of evolution as a debate about organic evolution. This view, based on the belief that a dichotomy of thought on the subject of evolution existed between B. H. Roberts and Joseph Fielding Smith, has become common among pro-evolution members of the church. As a result, the ensuing 1931 statement has been interpreted by some as official permission for members to believe in organic evolution. However, there is no evidence that the debate included the topic of evolution, and historically there was no strong disagreement between Joseph Fielding Smith and B. H. Roberts concerning evolution; they both rejected it, although to different degrees. B. H. Roberts wrote that the "hypothesis" of organic evolution was "destructive of the grand, central truth of all revelation,"
Later, Joseph Fielding Smith published his book Man: His Origin and Destiny, which denounced evolution without qualification. Similar statements of denunciation were made by Bruce R. McConkie, who in 1980 denounced evolution as one of "the seven deadly heresies." Evolution was also denounced by the conservative apostle Ezra Taft Benson, who in 1975 called on church members to use the Book of Mormon to combat evolution and several times denounced evolution as a "falsehood" on a par with socialism, rationalism, and humanism.
A dichotomy of opinion exists among church members today. Largely influenced by Smith, McConkie, and Benson, evolution is rejected by a large number of conservative church members. A minority accept evolution, supported in part by the debate between B. H. Roberts and Joseph Fielding Smith, in part by a large amount of scientific evidence, and in part by Joseph F. Smith's words that "the church itself has no philosophy about the modus operandi employed by the Lord in His creation of the world." Meanwhile, Brigham Young University, the largest private university owned and operated by the church, not only teaches evolution to its biology majors, but has also done significant research in evolution. BYU-I, another church-run school, also teaches it.
The church was opposed to the Equal Rights Amendment.
In 1995, the church issued The Family: A Proclamation to the World.
The church opposes same-sex marriage, but does not object to rights regarding hospitalization and medical care, fair housing and employment rights, or probate rights, so long as these do not infringe on the integrity of the family or the constitutional rights of churches and their adherents to administer and practice their religion free from government interference. The church supported a gay rights bill in Salt Lake City which bans discrimination against gay men and lesbians in housing and employment, calling them "common-sense rights."
Some church members have formed a number of unofficial support organizations, including Evergreen International, Affirmation: Gay & Lesbian Mormons, North Star, Disciples2, Wildflowers, Family Fellowship, GLYA (Gay LDS Young Adults), LDS Reconciliation, Gamofites and the Guardrail foundation. Church leaders have met with people from Evergreen International, Inc. and several gay rights leaders.
In 1967, a set of papyrus manuscripts were discovered in the Metropolitan Museum of Art that appear to be the manuscripts from which Joseph Smith said to have translated the Book of Abraham in 1835. These manuscripts were presumed lost in the Chicago fire of 1871. Analyzed by Egyptologists, the manuscripts were identified as The Book of the Dead, an ancient Egyptian funerary text. Moreover, the scholars' translations of the scrolls disagreed with Smith's purported translation. This discovery forced many Mormon apologists to moderate the earlier prevailing view that Smith's translations were literal one-to-one translations.
In the early 1980s, the apparent discovery of an early Mormon manuscript, which came to be known as the "Salamander Letter", received much publicity. This letter, reportedly discovered by a scholar named Mark Hofmann, alleged that the Book of Mormon was given to Joseph Smith by a being that changed itself into a salamander, not by an angel as the official church history recounted. The document was purchased by private collector Steven Christensen, but was still significantly publicized and even printed in the church's official magazine, the Ensign. The document, however, was revealed as a forgery in 1985, and Hofmann was arrested for two murders related to his forgeries.
In 1989, George P. Lee, a Navajo member of the First Quorum of the Seventy who had participated in the Indian Placement Program in his youth, was excommunicated. The church action occurred not long after he had submitted to the Church a 23-page letter critical of the program and the effect it had on Native American culture. In October 1994, Lee confessed to, and was convicted of, sexually molesting a 13-year-old girl in 1989. It is not known if church leaders had knowledge of this crime during the excommunication process.
In the late 1980s, the administration of Ezra Taft Benson formed what it called the Strengthening Church Members Committee, to keep files on potential church dissidents and collect their published material for possible later use in church disciplinary proceedings. The existence of this committee was first publicized by an anti-Mormon ministry in 1991, when it was referred to in a memo dated July 19, 1990 leaked from the office of the church's Presiding Bishopric.
At the 1992 Sunstone Symposium, dissident Mormon scholar Lavina Fielding Anderson accused the Committee of being "an internal espionage system," which prompted Brigham Young University professor and moderate Mormon scholar Eugene England to "accuse that committee of undermining the Church," a charge for which he later publicly apologized. The publicity concerning the statements of Anderson and England, however, prompted the church to officially acknowledge the existence of the committee. The Church explained that the Committee "provides local church leadership with information designed to help them counsel with members who, however well-meaning, may hinder the progress of the church through public criticism."
Official concern about the work of dissident scholars within the church led to the excommunication or disfellowshipping of six such scholars, dubbed the September Six, in September 1993.
By the 1960s and 1970s, the church became more media-savvy, and more self-conscious and protective of its public image. The church also became more involved in public discourse, using its new-found political and cultural influence and the media to affect its image, public morality, and Mormon scholarship, and to promote its missionary efforts. At the same time, the church struggled with how to deal with increasingly pluralistic voices within the church and within Mormonism. In general, this period has seen both an increase in cultural and racial diversity and extra-faith ecumenism, and a decrease in intra-faith pluralism.
Until the church's rapid growth after World War II, it had been seen in the eyes of the general public as a backward, non- or vaguely Christian polygamist cult in Utah. As the church's size began to merit new visibility in the world, the church seized upon the opportunity to re-define its public image, and to establish itself in the public mind as a mainstream Christian faith. At the same time, the church became publicly involved in numerous ecumenical and welfare projects that continue to serve as the foundation of its ecumenism today.
In the 1960s the church formed the Church Information Service with the goal of being ready to respond to media inquiries and generate positive media coverage. The organization kept a photo file to provide photos to the media for such events as Temple dedications. It also worked to get stories covering Family Home Evening, the church welfare plan and the church's youth activities in various publications.
As part of the church's efforts to re-position its image as that of a mainstream religion, the church began to moderate its earlier anti–Roman Catholic rhetoric. In Bruce R. McConkie's 1958 edition of Mormon Doctrine, he had stated his unofficial opinion that the Catholic Church was part of "the church of the devil" and "the great and abominable church" because it was among organizations that misled people away from following God's laws. In his 1966 edition of the same book, the specific reference to the Catholic Church was removed.
In 1973, the church recast its missionary discussions, making them more family-friendly and focused on building on common Christian ideals. The new discussions, named "A Uniform System for Teaching Families", de-emphasized the Great Apostasy, which previously held a prominent position just after the story of the First Vision. When the discussions were revised in the early 1980s, the new discussions dealt with the apostasy less conspicuously, and in later discussions, rather than in the first discussion.
According to Riess and Tickle, early Mormons rarely quoted from the Book of Mormon in their speeches and writings. It was not until the 1980s that it was cited regularly in speeches given by LDS Church leaders at the biannual general conferences. In 1982, the LDS Church subtitled the Book of Mormon "Another Testament of Jesus Christ." Apostle Boyd K. Packer stated that the scripture now took its place "beside the Old Testament and the New Testament. Riess and Tickle assert that the introduction of this subtitle was intended to emphasize the Christ-centered nature of the Book of Mormon. They assert that the LDS "rediscovery of the Book of Mormon in the late twentieth century is strongly connected to their renewed emphasis on the person and nature of Jesus Christ."
In 1995, the church announced a new logo design that emphasized the words "JESUS CHRIST" in large capital letters, and de-emphasized the words "The Church of" and "of Latter-day Saints".
On January 1, 2000, the First Presidency and the Quorum of the Twelve Apostles released a proclamation entitled "The Living Christ: The Testimony of the Apostles". This document commemorated the birth of Jesus and set forth the church's official view regarding Christ.
In 2001, the church sent out a press release encouraging reporters to use the full name of the church at the beginning of news articles, with following references to the "Church of Jesus Christ". The release discouraged the use of the term "Mormon Church".
The church has participated in several interfaith cooperation initiatives. The church has opened its broadcasting facilities (Bonneville International) to other Christian groups and has participated in the VISN Religious Interfaith Cable Television Network. The church has also participated in numerous joint humanitarian efforts with other churches. Lastly, the church has agreed not to baptize Holocaust victims by proxy.
In 2004, the church endorsed an amendment to the United States Constitution banning homosexual marriage. The church also announced its opposition to political measures that "confer legal status on any other sexual relationship" than a "man and a woman lawfully wedded as husband and wife."
On November 5, 2015, an update letter to LDS Church leaders for the Church Handbook was leaked. The policy banned a "child of a parent living in a same-gender relationship" from baby blessings, baptism, confirmation, priesthood ordination, and missionary service until the child was not living with their homosexual parent(s), was "of legal age", and "disavow[ed] the practice of same-gender cohabitation and marriage", in addition to receiving approval from the Office of the First Presidency. The policy update also added that entering a same-sex marriage as a type of "apostasy", mandating a disciplinary council. The next day, in a video interview, apostle D. Todd Christofferson clarified that the policy was "about love" and "protect[ing] children" from "difficulties, challenges, conflicts" where "parents feel one way and the expectations of the Church are very different". On November 13, the First Presidency released a letter clarifying that the policy applied "only to those children whose primary residence is with a couple living in a same-gender marriage or similar relationship" and that for children residing with parents in a same-sex relationship who had already received ordinances the policy would not require that "privileges be curtailed or that further ordinances be withheld". The next day around 1,500 members gathered across from the Church Office Building to submit their resignation letters in response to the policy change with thousands more resigning online in the weeks after Two months later, in a satellite broadcast, apostle Russell M. Nelson stated that the policy change was "revealed to President Monson" in a "sacred moment" when "the Lord inspired [him] ... to declare ... the will of the Lord". In April 2019, the church—then led by Nelson—reversed these policies, citing efforts to be more accepting to people of all kinds of backgrounds.
For over 100 years, the church was a major sponsor of Scouting programs for boys, particularly in the United States. The LDS Church was the largest chartered organization in the Boy Scouts of America (BSA), having joined the BSA as its first charter organization in 1913. In 2020, the church ended its relationship with the BSA and began an alternate, religion-centered youth program, which replaced all other youth programs. Prior to leaving the Scouting program, LDS Scouts made up nearly 20 percent of all enrolled Boy Scouts, more than any other church.
In 1887, the LDS Church was legally dissolved in the United States by the Edmunds–Tucker Act because of the church's practice of polygamy. For more than the next hundred years, the church as a whole operated as an unincorporated entity. During that time, tax-exempt corporations of the LDS Church included the Corporation of the Presiding Bishop of The Church of Jesus Christ of Latter-day Saints, which managed non-ecclesiastical real estate and other holdings; and the Corporation of the President of The Church of Jesus Christ of Latter-day Saints, which governed temples, other sacred buildings, and the church's employees. By 2021, the two had been merged into one corporate entity, legally named "The Church of Jesus Christ of Latter-day Saints."
In December 2019, a whistleblower alleged the church held over $100 billion in investment funds through its investment management company, Ensign Peak Advisors (EP); that it failed to use the funds for charitable purposes and instead used them in for-profit ventures; and that it misled contributors and the public about the usage and extent of those funds. In response, the church's First Presidency stated that "the Church complies with all applicable law governing our donations, investments, taxes, and reserves," and that "a portion" of funds received by the church are "methodically safeguarded through wise financial management and the building of a prudent reserve for the future". The church has not directly addressed the fund's size to the public, but third parties have treated the disclosures as legitimate.
In February 2023, the U.S. Securities and Exchange Commission (SEC) issued a $5 million penalty to the church and its investment company, EP. The SEC alleged that the church concealed its investments and their management in multiple shell companies from 1997 to 2019; the SEC believes these shell companies were approved by senior church leadership to avoid public transparency. The church released a statement that in 2000 EP "received and relied upon legal counsel regarding how to comply with its reporting obligations while attempting to maintain the privacy of the portfolio." After initial SEC concern in June 2019, the church stated that EP "adjusted its approach and began filing a single aggregated report." | [

Roberts to reconcile the fossil record with the scriptures by introducing a doctrine of pre-Adamite creation, and backing up this speculative doctrine using geology, biology, anthropology, and archeology. More conservative members of the Twelve Apostles, including Joseph Fielding Smith, rejected his speculation because it contradicted the idea that there was no death until after the fall of Adam. James E. Talmage published a book through the LDS Church that explicitly stated that organisms lived and died on this earth before the earth was fit for human habitation.",

This view, based on the belief that a dichotomy of thought on the subject of evolution existed between B. H.

As a result, the ensuing 1931 statement has been interpreted by some as official permission for members to believe in organic evolution. However, there is no evidence that the debate included the topic of evolution, and historically there was no strong disagreement between Joseph Fielding Smith and B. H. Roberts concerning evolution; they both rejected it, although to different degrees. B. H.

] | The history of the Church of Jesus Christ of Latter-day Saints has three main periods, described generally as: the early history during the lifetime of Joseph Smith, which is in common with most Latter Day Saint movement churches;
the "pioneer era" under the leadership of Brigham Young and his 19th-century successors;
the modern era beginning in the early 20th century as the practice of polygamy was discontinued and many members sought reintegration into U.S. society. The LDS Church originated in the burned-over district within Western New York. Joseph Smith, the founder of the Latter Day Saint movement, was raised in this region during the Second Great Awakening. Smith gained a small following in the late 1820s as he was dictating the Book of Mormon, which he said was a translation of inscriptions found on a set of golden plates buried near his home in Upstate New York by an Indigenous American prophet named Moroni. On April 6, 1830, at the home of Peter Whitmer in Fayette, New York, Smith organized the religion's first legal church entity, the Church of Christ. The church rapidly gained a following who viewed Smith as their prophet. The main body of the church moved first to Kirtland, Ohio, in the early 1830s, then to Missouri in 1838, where the 1838 Mormon War with other Missouri settlers ensued. On October 27, 1838, Lilburn W. Boggs, the Governor of Missouri, signed Missouri Executive Order 44, which called to expel adherents from the state. Approximately 15,000 Mormons fled to Illinois after their surrender at Far West on November 1, 1838. After fleeing from Missouri, Smith founded the city of Nauvoo, Illinois, which grew rapidly. When Smith was killed, Nauvoo had a population of about 12,000 people, nearly all members of Smith's church. After his death, a succession crisis ensued and the majority voted to accept the Quorum of the Twelve, led by Brigham Young, as the church's leading body. After suffering persecution in Illinois, Young left Nauvoo in 1846 and led his followers, the Mormon pioneers, to Salt Lake Valley. The Mormon pioneers then branched out to pioneer a large state called Deseret, establishing colonies that spanned from Canada to Mexico. Young incorporated the LDS Church as a legal entity and governed his followers as a theocratic leader, assuming both political and religious positions. He also publicized the previously secret practice of plural marriage, a form of polygamy. By 1857, tensions had again escalated between Latter-day Saints and other Americans, largely as a result of the teachings on polygamy and theocracy. During the Utah War, from 1857 to 1858, the United States Army conducted an invasion of Utah, after which Young agreed to be replaced by a non-Mormon territorial Governor, Alfred Cumming. The church, however, still wielded significant political power in Utah Territory. Even after Young died in 1877, many members continued the practice of polygamy despite opposition by the United States Congress. When tensions with the U.S. government came to a head in 1890, the church officially abandoned the public practice of polygamy in the United States and eventually stopped performing official polygamous marriages altogether after a Second Manifesto in 1904. Eventually, the church adopted a policy of excommunicating members who were found to be practicing polygamy, and today seeks to actively distance itself from polygamist fundamentalist groups. During the 20th century, the church became an international organization. The church first began engaging with mainstream American culture, and then with international cultures. It engaged especially in Latin American countries by sending out thousands of missionaries. The church began publicly supporting monogamy and the nuclear family, and at times played a role in political matters. One of the official changes to the organization during the modern era was the participation of black members in temple ceremonies, which began in 1978, reversing a policy originally instituted by Young. The church has also gradually changed its temple ceremony. There continue to be periodic changes in the structure and organization of the church. | 2001-10-30T15:45:24Z | 2023-12-31T05:00:43Z | [

5,943 | Christian eschatology | Christian eschatology, is a major branch of study within Christian theology, deals with the doctrine of the "last things", especially the Second Coming of Christ, or Parousia. Eschatology – the word derives from two Greek roots meaning "last" (ἔσχατος) and "study" (-λογία) – involves the study of "end things", whether of the end of an individual life, of the end of the age, of the end of the world, or of the nature of the Kingdom of God. Broadly speaking, Christian eschatology focuses on the ultimate destiny of individual souls and of the entire created order, based primarily upon biblical texts within the Old and New Testaments.
Christian eschatology looks to study and discuss matters such as death and the afterlife, Heaven and Hell, the Second Coming of Jesus, the resurrection of the dead, the rapture, the tribulation, millennialism, the end of the world, the Last Judgment, and the New Heaven and New Earth in the world to come.
Eschatological passages appear in many places in the Bible, in both the Old and New Testaments. Many extra-biblical examples of eschatological prophecies also exist, as well as extra-biblical ecclesiastical traditions relating to the subject.
Eschatology within early Christianity originated with the public life and preaching of Jesus. Jesus Himself referred to His Second Coming numerous times in the gospels: just a few examples are Matthew 24:27; Matthew 24:37–39; Matthew 26:64; Mark 14:62. Christian eschatology is an ancient branch of study in Christian theology, informed by Biblical texts such as the Olivet discourse (recorded in Matthew 24-25, Mark 13, and Luke 21), The Sheep and the Goats, and other discourses of end times by Jesus, with the doctrine of the Second Coming discussed by Paul the Apostle in his epistles, both the authentic and the disputed ones. Other eschatological doctrines can be found in the Epistle of James, the First Epistle of Peter, and the First Epistle of John. According to some scholars, the Second Epistle of Peter explains that God is patient and has not yet brought about the Second Coming of Christ, in order that more people will have the chance to reject evil and find salvation (3:3–9); therefore, it calls on Christians to wait patiently for the Parousia and to study scripture. Other scholars, however, believe that the New Testament epistles are an exhortation to the early church believers to patiently expect the imminent return of Christ, predicted by Himself on several occasions in the gospels. The First Epistle of Clement, written by Pope Clement I in ca. 95, criticizes those who had doubts about the faith because the Second Coming had, in his view, not yet occurred.
Christian eschatology is also discussed by Ignatius of Antioch (c. 35–107 AD) in his epistles, then given more consideration by the Christian apologist, Justin Martyr (c. 100–165). Treatment of eschatology continued in the West in the teachings of Tertullian (c. 160–225), and was given fuller reflection and speculation soon after by Origen (c. 185–254). The word was used first by the Lutheran theologian Abraham Calovius (1612–1686) but only came into general usage in the 19th century.
The growing modern interest in eschatology is tied to developments in Anglophone Christianity. Puritans in the 18th and 19th centuries were particularly interested in a postmillennial hope which surrounded Christian conversion. This would be contrasted with the growing interest in premillennialism, advocated by dispensational figures such as J. N. Darby. Both of these strands would have significant influences on the growing interests in eschatology in Christian missions and in Christianity in West Africa and Asia. However, in the 20th century, there would be a growing number of German scholars such as Jürgen Moltmann and Wolfhart Pannenberg who would likewise be interested in eschatology.
In the 1800s, a group of Christian theologians inclusive of Ellen G. White, William Miller and Joseph Bates began to study eschatological implications revealed in the Book of Daniel and the Book of Revelation. Their interpretation of Christian eschatology resulted in the founding of the Seventh-day Adventist church.
The following approaches arose from the study of Christianity's most central eschatological document, the Book of Revelation, but the principles embodied in them can be applied to all prophecy in the Bible. They are by no means mutually exclusive and are often combined to form a more complete and coherent interpretation of prophetic passages. Most interpretations fit into one, or a combination, of these approaches. The alternate methods of prophetic interpretation, Futurism and Preterism which came from Jesuit writings, were brought about to oppose the Historicism interpretation which had been used from Biblical times that Reformers used in teaching that the Antichrist was the Papacy or the power of the Roman Catholic Church.
Preterism is a Christian eschatological view that interprets some (partial preterism) or all (full preterism) prophecies of the Bible as events which have already happened. This school of thought interprets the Book of Daniel as referring to events that happened from the 7th century BC until the first century AD, while seeing the prophecies of Revelation as events that happened in the first century AD. Preterism holds that Ancient Israel finds its continuation or fulfillment in the Christian church at the destruction of Jerusalem in AD 70.
Historically, preterists and non-preterists have generally agreed that the Jesuit Luis de Alcasar (1554–1613) wrote the first systematic preterist exposition of prophecy, Vestigatio arcani sensus in Apocalypsi (published in 1614), during the Counter-Reformation.
Historicism, a method of interpretation of biblical prophecies, associates symbols with historical persons, nations or events. It can result in a view of progressive and continuous fulfillment of prophecy covering the period from biblical times to what they view as a possible future Second Coming of Christ. Most Protestant Reformers from the Reformation into the 19th century held historicist views.
In Futurism, parallels may be drawn with historical events, but most eschatological prophecies are chiefly referring to events which have not yet been fulfilled, but will take place at the end of the age and the end of the world. Most prophecies will be fulfilled during a time of global chaos known as the Great Tribulation and afterwards. Futurist beliefs usually have a close association with Premillennialism and Dispensationalism.
Idealism (also called the spiritual approach, the allegorical approach, the nonliteral approach, and many other names) in Christian eschatology is an interpretation of the Book of Revelation that sees all of the imagery of the book as symbols.
Jacob Taubes writes that idealist eschatology came about as Renaissance thinkers began to doubt that the Kingdom of Heaven had been established on earth, or would be established, but still believed in its establishment. Rather than the Kingdom of Heaven being present in society, it is established subjectively for the individual.
F. D. Maurice interpreted the Kingdom of Heaven idealistically as a symbol representing society's general improvement, instead of a physical and political kingdom. Karl Barth interprets eschatology as representing existential truths that bring the individual hope, rather than history or future-history. Barth's ideas provided fuel for the Social Gospel philosophy in America, which saw social change not as performing "required" good works, but because the individuals involved felt that Christians could not simply ignore society's problems with future dreams.
Different authors have suggested that the Beast represents various social injustices, such as exploitation of workers, wealth, the elite, commerce, materialism, and imperialism. Various Christian anarchists, such as Jacques Ellul, have identified the State and political power as the Beast. Other scholars identify the Beast with the Roman empire of the first century AD, but recognize that the Beast may have significance beyond its identification with Rome. For example, Craig R. Koester says "the vision [of the beast] speaks to the imperial context in which Revelation was composed, but it does so with images that go beyond that context, depicting the powers at work in the world in ways that continue to engage readers of subsequent generations." And his comments on the whore of Babylon are more to the point: "The whore [of Babylon] is Rome, yet more than Rome." It "is the Roman imperial world, which in turn represents the world alienated from God." As Stephen Smalley puts it, the beast represents "the powers of evil which lie behind the kingdoms of this world, and which encourage in society, at any moment in history, compromise with the truth and opposition to the justice and mercy of God."
It is distinct from Preterism, Futurism and Historicism in that it does not see any of the prophecies (except in some cases the Second Coming, and Final Judgment) as being fulfilled in a literal, physical, earthly sense either in the past, present or future, and that to interpret the eschatological portions of the Bible in a historical or future-historical fashion is an erroneous understanding.
Expositors of the traditional Protestant interpretation of Revelation known as Historicism have often maintained that Revelation was written in AD 96 and not AD 70. Edward Bishop Elliott, in the Horae Apocalypticae (1862), argues that John wrote the book in exile on Patmos "at the close of the reign of Domitian; that is near the end of the year 95 or beginning of 96". He notes that Domitian was assassinated in September 96. Elliot begins his lengthy review of historical evidence by quoting Irenaeus, a disciple of Polycarp. Polycarp was a disciple of the Apostle John. Irenaeus mentions that the Apocalypse was seen "no very long time ago [but] almost in our own age, toward the end of the reign of Domitian".
Other historicists have seen no significance in the date that Revelation was written, and have even held to an early date while Kenneth L. Gentry, Jr., makes an exegetical and historical argument for the pre-AD 70 composition of Revelation.
The division between these interpretations can be somewhat blurred. Most futurists are expecting a rapture of the Church, an antichrist, a Great Tribulation and a second coming of Christ in the near future. But they also accept certain past events, such as the rebirth of the State of Israel and the reunification of Jerusalem as prerequisites to them, in a manner which the earlier historicists have done with other dates. Futurists, who do not normally use the day-year principle, interpret the Prophecy of Seventy Weeks in Daniel 9:24 as years, just as historicists do. Most historicists have chosen timelines, from beginning to end, entirely in the past, but some, such as Adam Clarke, have timelines which also commenced with specific past events, but require a future fulfillment. In his commentary on Daniel 8:14 published in 1831, he stated that the 2,300-year period should be calculated from 334 BC, the year Alexander the Great began his conquest of the Persian Empire. His calculation resulted in the year 1966. He seems to have overlooked the fact that there is no "year zero" between BC and AD dates. For example, the year following 1 BC is 1 AD. Thus his calculations should have required an additional year, ending in 1967. He was not anticipating a literal regathering of the Jewish people prior to the second coming of Christ. But the date is of special significance to futurists since it is the year of Jerusalem's capture by Israeli forces during the Six-Day War. His commentary on Daniel 7:25 contains a 1260-year period commencing in 755 AD and ending in 2015.
Premillennialism can be divided into two common categories: Historic Premillennialism and Dispensational Premillennialism. Historic Premillennialism is usually associated with post-tribulation "rapture" and does not see a strong distinction between ethnic Israel and the Church. Dispensational Premillennialism can be associated with any of the three rapture views but is often associated with a pretribulation rapture. Dispensationalism also sees a stronger distinction between ethnic Israel and the Church.
Premillennialism usually posits that Christ's second coming will inaugurate a literal thousand-year earthly kingdom. Christ's return will coincide with a time of great tribulation. At this time, there will be a resurrection of the people of God who have died, and a rapture of the people of God who are still living, and they will meet Christ at his coming. A thousand years of peace will follow (the millennium), during which Christ will reign and Satan will be imprisoned in the Abyss. Those who hold to this view usually fall into one of the following three categories:
Pretribulationists believe that the second coming will be in two stages separated by a seven-year period of tribulation. At the beginning of the tribulation, true Christians will rise to meet the Lord in the air (the Rapture). Then follows a seven-year period of suffering in which the Antichrist will conquer the world and persecute those who refuse to worship him. At the end of this period, Christ returns to defeat the Antichrist and establish the age of peace. This position is supported by a scripture which says, "God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ." [1 Thess 5:9]
Midtribulationists believe that the Rapture will take place at the halfway point of the seven-year tribulation, i.e. after 3½ years. It coincides with the "abomination of desolation"—a desecration of the temple where the Antichrist puts an end to the Jewish sacrifices, sets up his own image in the temple, and demands that he be worshiped as God. This event begins the second, most intense part of the tribulation.
Some interpreters find support for the "midtrib" position by comparing a passage in Paul's epistles with the book of Revelation. Paul says, "We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed" (1 Cor 15:51–52). Revelation divides the great tribulation into four sets of increasingly catastrophic judgments: the Seven Seals, the Seven Trumpets, the Seven Thunders (Rev 10:1–4) and the Seven Bowls, in that order. If the "last trumpet" of Paul is equated with the last trumpet of Revelation and the revelation of the scroll of the Seven Thunders, the Rapture would be in the middle of the Tribulation. (Not all interpreters agree with this literal interpretation of the chronology of Revelation, however.)
Posttribulationists hold that Christ will not return until the end of the tribulation. Christians, rather than being raptured at the beginning of the tribulation, or halfway through, will live through it and suffer for their faith during the ascendancy of the Antichrist. Proponents of this position believe that the presence of believers during the tribulation is necessary for a final evangelistic effort during a time when external conditions will combine with the Gospel message to bring great numbers of converts into the Church in time for the beginning of the Millennium.
Postmillennialism is an interpretation of chapter 20 of the Book of Revelation which sees Christ's second coming as occurring after the "Millennium", a Golden Age in which Christian ethics prosper. The term subsumes several similar views of the end times, and it stands in contrast to premillennialism and, to a lesser extent, amillennialism.
Postmillennialism holds that Jesus Christ establishes his kingdom on earth through his preaching and redemptive work in the first century and that he equips his church with the gospel, empowers her by the Spirit, and charges her with the Great Commission (Matt 28:19) to disciple all nations. Postmillennialism expects that eventually the vast majority of people living will be saved. Increasing gospel success will gradually produce a time in history prior to Christ's return in which faith, righteousness, peace, and prosperity will prevail in the affairs of men and of nations. After an extensive era of such conditions Jesus Christ will return visibly, bodily, and gloriously, to end history with the general resurrection and the final judgment after which the eternal order follows.
Postmillennialism was a dominant theological belief among American Protestants who promoted reform movements in the 19th and 20th century such as abolitionism and the Social Gospel. Postmillennialism has become one of the key tenets of a movement known as Christian Reconstructionism. It has been criticized by 20th century religious conservatives as an attempt to immanentize the eschaton.
Amillennialism, in Christian eschatology, involves the rejection of the belief that Jesus will have a literal, thousand-year-long, physical reign on the earth. This rejection contrasts with premillennial and some postmillennial interpretations of chapter 20 of the Book of Revelation.
The amillennial view regards the "thousand years" mentioned in Revelation 20 as a symbolic number, not as a literal description; amillennialists hold that the millennium has already begun and is identical with the current church age. Amillennialism holds that while Christ's reign during the millennium is spiritual in nature, at the end of the church age, Christ will return in final judgment and establish a permanent reign in the new heaven and new earth.
Many proponents dislike the name "amillennialism" because it emphasizes their differences with premillennialism rather than their beliefs about the millennium. "Amillennial" was actually coined in a pejorative way by those who hold premillennial views. Some proponents also prefer alternate terms such as nunc-millennialism (that is, now-millennialism) or realized millennialism, although these other names have achieved only limited acceptance and usage.
There were different schools of thought on the afterlife in Judea during the first century AD. The Sadducees, who recognized only the Torah (the first five books of the Old Testament) as authoritative, did not believe in an afterlife or any resurrection of the dead. The Pharisees, who accepted the Torah as well as additional scriptures, believed in the resurrection of the dead; it is known to have been a major point of contention between the two groups. The Pharisees based their belief on Biblical passages such as Daniel 12:2 which says: "Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt."
Some traditions (notably, the Seventh-day Adventists) teach that the soul sleeps after death and will not awaken until the resurrection of the dead. Others believe the soul goes to an intermediate place where it will live consciously until the resurrection of the dead.
By "soul", Seventh-day Adventist theologians mean the physical person (monism), and that no component of human nature survives death. Therefore, each human will be "recreated" at resurrection. The Book of Ezekiel provides substantiation for the assertion that souls experience mortality: "Behold, all souls are Mine; The soul of the father as well as the soul of the son is Mine. The soul who sins shall die." (Ezekiel 18:4)
This alludes to the Catholic belief in a spiritual state known as Purgatory during which souls not condemned to Hell but not completely pure go through a final process of purification before their full acceptance into Heaven.
The Catechism of the Catholic Church (CCC) says:
Eastern Orthodoxy and Protestantism do not believe in Purgatory as such, but the Orthodox Church posits a period of continued sanctification after death. While the Eastern Orthodox Church rejects the term purgatory, it acknowledges an intermediate state after death and before final judgment, and offers prayer for the dead. In general, Protestant churches reject the Catholic doctrine of purgatory (although some teach the existence of an intermediate state). The general Protestant view is that the Bible, from which Protestants exclude deuterocanonical books such as 2 Maccabees, contains no overt, explicit discussion of purgatory.
There are many passages in the Bible, both Old and New Testaments, which speak of a time of terrible tribulation such as has never been known, a time of natural and human-made disasters on an awesome scale. Jesus said that at the time of his coming, "There will be great tribulation, such as has not been since the beginning of the world to this time, no, nor ever will be. And unless those days were shortened, no flesh would be saved; but for the elect's sake, those days will be shortened." [Matt 24:21–22]
Furthermore, the Messiah's return and the tribulation that accompanies it will come at a time when people are not expecting it:
Of that day and hour no-one knows; no, not even the angels of heaven, but My Father only. But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, until the flood came and took them all away, so also will the coming of the Son of Man be.
Paul echoes this theme, saying, "For when they say, 'Peace and safety!' then sudden destruction comes upon them."
The abomination of desolation (or desolating sacrilege) is a term found in the Hebrew Bible, in the book of Daniel. The term is used by Jesus Christ in the Olivet discourse, according to both the Gospel of Matthew and the Gospel of Mark. In the Matthew account, Jesus is presented as quoting Daniel explicitly.
This verse in the Olivet Discourse also occurs in the Gospel of Luke.
Many biblical scholars conclude that Matthew 24:15 and Mark 13:14 are prophecies after the event about the siege of Jerusalem in AD 70 by the Roman general Titus (see Dating of the Gospel of Mark).
Preterist Christian commentators believe that Jesus quoted this prophecy in Mark 13:14 as referring to an event in his "1st century disciples'" immediate future, specifically the pagan Roman forces during the siege of Jerusalem in 70 AD.
Futurist Christians consider the "Abomination of Desolation" prophecy of Daniel mentioned by Jesus in Matthew 24:15 and Mark 13:14 as referring to an event in the end time future, when a 7-year peace treaty will be signed between Israel and a world ruler called "the man of lawlessness", or the "Antichrist" affirmed by the writings of the Apostle Paul in 2 Thessalonians.
Other scholars conclude that the Abomination of Desolation refers to the Crucifixion, an attempt by the emperor Hadrian to erect a statue to Jupiter in the Jewish temple, or an attempt by Caligula to have a statue depicting him as Zeus built in the temple.
Many interpreters calculate the length of the tribulation at seven years. The key to this understanding is the "seventy weeks prophecy" in the book of Daniel. The Prophecy of Seventy Septets (or literally 'seventy times seven') appears in the angel Gabriel's reply to Daniel, beginning with verse 22 and ending with verse 27 in the ninth chapter of the Book of Daniel, a work included in both the Jewish Tanakh and the Christian Bible; as well as the Septuagint. The prophecy is part of both the Jewish account of history and Christian eschatology.
The prophet has a vision of the angel Gabriel, who tells him, "Seventy weeks are determined for your people and for your holy city (i.e., Israel and Jerusalem)." [Dan 9:24] After making a comparison with events in the history of Israel, many scholars have concluded that each day in the seventy weeks represents a year. The first sixty-nine weeks are interpreted as covering the period until Christ's first coming, but the last week is thought to represent the years of the tribulation which will come at the end of this age, directly preceding the millennial age of peace:
This is an obscure prophecy, but in combination with other passages, it has been interpreted to mean that the "prince who is to come" will make a seven-year covenant with Israel that will allow the rebuilding of the temple and the reinstitution of sacrifices, but "in the middle of the week", he will break the agreement and set up an idol of himself in the temple and force people to worship it—the "abomination of desolation". Paul writes:
The rapture is an eschatological term used by certain Christians, particularly within branches of North American evangelicalism, referring to an end time event when all Christian believers—living and dead—will rise into Heaven and join Christ. Some adherents believe this event is predicted and described in Paul's First Epistle to the Thessalonians in the Bible, where he uses the Greek harpazo (ἁρπάζω), meaning to snatch away or seize. Though it has been used differently in the past, the term is now often used by certain believers to distinguish this particular event from the Second Coming of Jesus Christ to Earth mentioned in Second Thessalonians, Gospel of Matthew, First Corinthians, and Revelation, usually viewing it as preceding the Second Coming and followed by a thousand-year millennial kingdom. Adherents of this perspective are sometimes referred to as premillennialist dispensationalists, but amongst them there are differing viewpoints about the exact timing of the event.
The term "rapture" is especially useful in discussing or disputing the exact timing or the scope of the event, particularly when asserting the "pre-tribulation" view that the rapture will occur before, not during, the Second Coming, with or without an extended Tribulation period. The term is most frequently used among evangelical and fundamentalist Christians in the United States. Other, older uses of "rapture" were simply as a term for any mystical union with God or for eternal life in Heaven with God.
There are differing views among Christians regarding the timing of Christ's return, such as whether it will occur in one event or two, and the meaning of the aerial gathering described in 1 Thessalonians 4. Many Christians do not subscribe to rapture-oriented theological views. Though the term "rapture" is derived from the text of the Latin Vulgate of 1 Thess. 4:17—"we will be caught up", (Latin: rapiemur), Catholics, as well as Eastern Orthodox, Anglicans, Lutherans and most Reformed Christians, do not generally use "rapture" as a specific theological term, nor do any of these bodies subscribe to the premillennialist dispensationalist theological views associated with its use, but do believe in the phenomenon—primarily in the sense of the elect gathering with Christ in Heaven after his Second Coming. These denominations do not believe that a group of people is left behind on earth for an extended Tribulation period after the events of 1 Thessalonians 4:17.
Pre-tribulation rapture theology originated in the eighteenth century, with the Puritan preachers Increase Mather and Cotton Mather, and was popularized extensively in the 1830s by John Nelson Darby and the Plymouth Brethren, and further in the United States by the wide circulation of the Scofield Reference Bible in the early 20th century. Some, including Grant Jeffrey, maintain that an earlier document called Ephraem or Pseudo-Ephraem already supported a pre-tribulation rapture.
The Bible states:
Many, but not all, Christians believe:
In Matthew 24 Jesus states:
These false Christs will perform great signs and are no ordinary people "For they are spirits of demons, performing signs, which go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty." (Revelation 16:14) Satan's angels will also appear as godly clergymen, and Satan will appear as an angel of light. "For such are false apostles, deceitful workers, transforming themselves into apostles of Christ. And no wonder! For Satan himself transforms himself into an angel of light. Therefore it is no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works." (2 Corinthians 11:13–15)
After Jesus meets his followers "in the air", the marriage of the Lamb takes place: "Let us be glad and rejoice and give him glory, for the marriage of the Lamb has come, and his wife has made herself ready. And to her was granted that she should be arrayed in fine linen, clean and bright, for the fine linen is the righteous acts of the saints" [Rev 19:7–8]. Christ is represented throughout Revelation as "the Lamb", symbolizing the giving of his life as an atoning sacrifice for the people of the world, just as lambs were sacrificed on the altar for the sins of Israel. His "wife" appears to represent the people of God, for she is dressed in the "righteous acts of the saints". As the marriage takes place, there is a great celebration in heaven which involves a "great multitude" [Rev 19:6].
The word resurrection comes from the Latin resurrectus, which is the past participle of resurgere, meaning to rise again. Although the doctrine of the resurrection comes to the forefront in the New Testament, it predates the Christian era. There is an apparent reference to the resurrection in the book of Job, where Job says, "I know that my redeemer lives, and that he will stand at the latter day upon the earth. And though... worms destroy this body, yet in my flesh I will see God" [Job 19:25–27]. Again, the prophet Daniel writes, "Many of those who sleep in the dust of the earth shall awake, some to everlasting life, some to shame and everlasting contempt" [Dan 12:2]. Isaiah says: "Your dead will live. Together with my dead body, they will arise. Awake and sing, you who dwell in dust, for your dew is like the dew of herbs, and the earth will cast out the dead" [Isa. 26:19].
This belief was still common among the Jews in New Testament times, as exemplified by the passage which relates the raising of Lazarus from the dead. When Jesus told Lazarus' sister, Martha, that Lazarus would rise again, she replied, "I know that he will rise again in the resurrection at the last day" [Jn 11:24]. Also, one of the two main branches of the Jewish religious establishment, the Pharisees, believed in and taught the future resurrection of the body [cf Acts 23:1–8].
An interpretation of the New Testament is the understanding that there will be two resurrections. Revelation says: "Blessed and holy is he who has part in the first resurrection. Over such, the second death has no power, but they will be priests of God and of Christ, and will reign with him a thousand years" [Rev 20:6]. The rest of the dead "did not live again until the thousand years were finished" [Rev 20:5].
Despite this, there are various interpretations:
The Gospel authors wrote that our resurrection bodies will be different from those we have now. Jesus said, "In the resurrection, they neither marry nor are given in marriage, but are like the angels of God in heaven" [Mt 22:30]. Paul adds, "So also is the resurrection of the dead: the body ... is sown a natural body; it is raised a spiritual body" [1 Co. 15:42–44].
According to the Catechism of the Catholic Church the body after resurrection is changed into a spiritual, imperishable body:
[999] Christ is raised with his own body: "See my hands and my feet, that it is I myself" [553]; but he did not return to an earthly life. So, in him, "all of them will rise again with their own bodies which they now bear," but Christ "will change our lowly body to be like his glorious body," into a "spiritual body" [554]
In some ancient traditions, it was held that the person would be resurrected at the same spot where they died and were buried (just as in the case of Jesus' resurrection). For example, in the early medieval biography of St Columba written by Adomnan of Iona, Columba at one point prophesies to a penitent at the monastery on Iona that his resurrection would be in Ireland and not in Iona, and this penitent later died at a monastery in Ireland and was buried there.
Although Martin Luther personally believed and taught resurrection of the dead in combination with soul sleep, this is not a mainstream teaching of Lutheranism and most Lutherans traditionally believe in resurrection of the body in combination with the immortal soul.
Several churches, such as the Anabaptists and Socinians of the Reformation, then Seventh-day Adventist Church, Christadelphians, Jehovah's Witnesses, and theologians of different traditions reject the idea of the immortality of a non-physical soul as a vestige of Neoplatonism, and other pagan traditions. In this school of thought, the dead remain dead (and do not immediately progress to a Heaven, Hell, or Purgatory) until a physical resurrection of some or all of the dead occurs at the end of time. Some groups, Christadelphians in particular, consider that it is not a universal resurrection, and that at this time of resurrection that the Last Judgment will take place.
Megiddo is mentioned twelve times in the Old Testament, ten times in reference to the ancient city of Megiddo, and twice with reference to "the plain of Megiddo", most probably simply meaning "the plain next to the city". None of these Old Testament passages describes the city of Megiddo as being associated with any particular prophetic beliefs. The one New Testament reference to the city of Armageddon found in Revelation 16:16 also makes no specific mention of any armies being predicted to one day gather in this city, but instead seems to predict only that "they (will gather) the kings together to .... Armageddon". The text does however seem to imply, based on the text from the earlier passage of Revelation 16:14, that the purpose of this gathering of kings in the "place called Armageddon" is "for the war of the great day of God, the Almighty". Because of the seemingly highly symbolic and even cryptic language of this one New Testament passage, some Christian scholars conclude that Mount Armageddon must be an idealized location. R. J. Rushdoony says, "There are no mountains of Megiddo, only the Plains of Megiddo. This is a deliberate destruction of the vision of any literal reference to the place." Other scholars, including C. C. Torrey, Kline and Jordan argue that the word is derived from the Hebrew moed (מועד), meaning "assembly". Thus, "Armageddon" would mean "Mountain of Assembly," which Jordan says is "a reference to the assembly at Mount Sinai, and to its replacement, Mount Zion."
The traditional viewpoint interprets this biblical prophecy to be symbolic of the progression of the world toward the "great day of God, the Almighty" in which the great looming mountain of God's just and holy wrath is poured out against unrepentant sinners, led by Satan, in a literal end-of-the-world final confrontation. Armageddon is the symbolic name given to this event based on scripture references regarding divine obliteration of God's enemies. The hermeneutical method supports this position by referencing Judges 4 and 5 where God miraculously destroys the enemy of His elect, Israel, at Megiddo, also called the Valley of Josaphat.
Christian scholar William Hendriksen says:
For this cause, Har Magedon is the symbol of every battle in which, when the need is greatest and believers are oppressed, the Lord suddenly reveals His power in the interest of His distressed people and defeats the enemy. When Sennacherib's 185,000 are slain by the Angel of Jehovah, that is a shadow of the final Har-Magedon. When God grants a little handful of Maccabees a glorious victory over an enemy which far outnumbers it, that is a type of Har-Magedon. But the real, the great, the final Har Magedon coincides with the time of Satan's little season. Then the world, under the leadership of Satan, anti-Christian government, and anti-Christian religion—the dragon, the beast, and the false prophet—is gathered against the Church for the final battle, and the need is greatest; when God's children, oppressed on every side, cry for help; then suddenly, Christ will appear on the clouds of glory to deliver his people; that is Har-Magedon.
Millennialism (from millennium, Latin for "a thousand years"), or chiliasm (from the Greek equivalent), is the belief that a Golden Age or Paradise will occur on Earth prior to the final judgment and future eternal state of the "World to Come".
Christian millennialism developed out of a Christian interpretation of Jewish apocalypticism. Christian millennialist thinking is primarily based upon the Book of Revelation, specifically 20:1–4, which describes the vision of an angel who descended from heaven with a large chain and a key to a bottomless pit, and captured Satan, imprisoning him for a thousand years:
Then I saw an angel coming down from heaven, holding in his hand the key of the bottomless pit and a great chain. And he seized the dragon, that ancient serpent, who is the Devil and Satan, and bound him for a thousand years . . . that he should deceive the nations no more. . . . Then I saw thrones, and seated on them were those to whom judgment was committed. Also I saw the souls of those who had been beheaded for their testimony to Jesus and for the word of God. . . . They came to life and reigned with Christ a thousand years.
The Book of Revelation then describes a series of judges who are seated on thrones, as well as his vision of the souls of those who were beheaded for their testimony in favor of Jesus and their rejection of the mark of the beast:
They came to life and reigned with Christ a thousand years. (The rest of the dead did not come to life until the thousand years were ended.) This is the first resurrection. Blessed and holy are those who share in the first resurrection. Over these the second death has no power, but they will be priests of God and of Christ, and they will reign with him a thousand years.
Thus, Revelation characterizes a millennium where Christ and the Father will rule over a theocracy of the righteous. While there are an abundance of biblical references to such a kingdom of God throughout the Old and New Testaments, this is the only reference in the Bible to such a period lasting one thousand years. The literal belief in a thousand-year reign of Christ is a later development in Christianity, as it does not seem to have been present in first century texts.
According to the Bible, the Millennial age of peace all but closes the history of planet Earth. However, the story is not yet finished: "When the thousand years have expired, Satan will be released from his prison and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number is as the sand of the sea." [Rev 20:7–8]
There is continuing discussion over the identity of Gog and Magog. In the context of the passage, they seem to equate to something like "east and west". There is a passage in Ezekiel, however, where God says to the prophet, "Set your face against Gog, of the land of Magog, the prince of Rosh, Meshech, and Tubal, and prophesy against him." [Ezek 38:2] Gog, in this instance, is the name of a person of the land of Magog, who is ruler ("prince") over the regions of Rosh, Meshech, and Tubal. Ezekiel says of him: "You will ascend, coming like a storm, covering the land like a cloud, you and all your troops and many peoples with you..." [Ezek 38:2]
Despite this huge show of force, the battle will be short-lived, for Ezekiel, Daniel, and Revelation all say that this last desperate attempt to destroy the people and the city of God will end in disaster: "I will bring him to judgment with pestilence and bloodshed. I will rain down on him and on his troops, and on the many peoples who are with him: flooding rain, great hailstones, fire and brimstone." [Ezek 38:22] Revelation concurs: "Fire came down from God out of heaven and devoured them." [Rev 20:9] It may be that the images of fire raining down are an ancient vision of modern weapons, others would say a supernatural intervention by God, yet others that they refer to events in history, and some would say they are symbolic of larger ideas and should not be interpreted literally.
Following the defeat of Gog, the last judgment begins: "The devil, who deceived them, was cast into the lake of fire and brimstone where the beast and the false prophet are, and they will be tormented day and night forever and ever" [Rev 20:10]. Satan will join the Antichrist and the False Prophet, who were condemned to the lake of fire at the beginning of the Millennium.
Following Satan's consignment to the lake of fire, his followers come up for judgment. This is the "second resurrection", and all those who were not a part of the first resurrection at the coming of Christ now rise up for judgment:
I saw a great white throne and him who sat on it, from whose face the earth and the heaven fled away, and there was found no place for them. And the sea gave up the dead who were in it, and Death and Hades delivered up the dead who were in them. And they were judged, each one according to his works. And Death and Hades were cast into the lake of fire. This is the second death. And anyone not found written in the Book of Life was cast into the lake of fire. [Rev 20:11–15]
John had earlier written, "Blessed and holy is he who has part in the first resurrection. Over such the second death has no power" [Rev 20:6]. Those who are included in the Resurrection and the Rapture are excluded from the final judgment, and are not subject to the second death. Due to the description of the seat upon which the Lord sits, this final judgment is often referred to as the Great White Throne Judgment.
A decisive factor in the Last Judgement will be the question, if the corporal works of mercy were practiced or not during lifetime. They rate as important acts of charity. Therefore, and according to the biblical sources (Matt 5:31–46), the conjunction of the Last Judgement and the works of mercy is very frequent in the pictorial tradition of Christian art.
But, in accordance with his promise, we wait for new heavens and a new earth, where righteousness is at home.
The focus turns to one city in particular, the New Jerusalem. Once again, we see the imagery of the marriage: "I, John, saw the holy city, New Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband" [Rev 21:2]. In the New Jerusalem, God "will dwell with them, and they will be his people, and God himself will be with them and be their God..." [Rev 21:3]. As a result, there is "no temple in it, for the Lord God Almighty and the Lamb are its temple." Nor is there a need for the sun to give its light, "for the glory of God illuminated it, and the Lamb is its light" [Rev 21:22–23]. The city will also be a place of great peace and joy, for "God will wipe away every tear from their eyes. There will be no more death, nor sorrow, nor crying; and there will be no more pain, for the former things have passed away" [Rev 21:4].
The city itself has a large wall with twelve gates in it which are never shut, and which have the names of the twelve tribes of Israel written on them. Each of the gates is made of a single pearl, and there is an angel standing in each one. The wall also has twelve foundations which are adorned with precious stones, and upon the foundations are written the names of the twelve apostles. The gates and foundations are often interpreted as symbolizing the people of God before and after Christ.
The city and its streets are pure gold, but not like the gold we know, for this gold is described as being like clear glass. The city is square in shape, and is twelve thousand furlongs long and wide (fifteen hundred miles). If these are comparable to earthly measurements, the city will cover an area about half the size of the contiguous United States. The height is the same as the length and breadth, and although this has led most people to conclude that it is shaped like a cube, it could also be a pyramid.
The city has a river which proceeds "out of the throne of God and of the Lamb". Next to the river is the tree of life, which bears twelve fruits and yields its fruit every month. The last time we saw the tree of life was in the Garden of Eden [Gen 2:9]. God drove Adam and Eve out from the garden, guarding it with cherubim and a flaming sword, because it gave eternal life to those who ate of it In the New Jerusalem, the tree of life reappears, and everyone in the city has access to it. Genesis says that the earth was cursed because of Adam's sin, but the author of John writes that in the New Jerusalem, "there will be no more curse."
The Evangelical Dictionary of Theology (Baker, 1984) says:
The rich symbolism reaches beyond our finest imaginings, not only to the beatific vision but to a renewed, joyous, industrious, orderly, holy, loving, eternal, and abundant existence. Perhaps the most moving element in the description is what is missing: there is no temple in the New Jerusalem, 'because the Lord God Almighty and the Lamb are its temple.' Vastly outstripping the expectations of Judaism, this stated omission signals the ultimate reconciliation. | [

"text": "Christian eschatology, is a major branch of study within Christian theology, deals with the doctrine of the \"last things\", especially the Second Coming of Christ, or Parousia. Eschatology – the word derives from two Greek roots meaning \"last\" (ἔσχατος) and \"study\" (-λογία) – involves the study of \"end things\", whether of the end of an individual life, of the end of the age, of the end of the world, or of the nature of the Kingdom of God. Broadly speaking, Christian eschatology focuses on the ultimate destiny of individual souls and of the entire created order, based primarily upon biblical texts within the Old and New Testaments.",

"text": "Eschatology within early Christianity originated with the public life and preaching of Jesus. Jesus Himself referred to His Second Coming numerous times in the gospels: just a few examples are Matthew 24:27; Matthew 24:37–39; Matthew 26:64; Mark 14:62. Christian eschatology is an ancient branch of study in Christian theology, informed by Biblical texts such as the Olivet discourse (recorded in Matthew 24-25, Mark 13, and Luke 21), The Sheep and the Goats, and other discourses of end times by Jesus, with the doctrine of the Second Coming discussed by Paul the Apostle in his epistles, both the authentic and the disputed ones. Other eschatological doctrines can be found in the Epistle of James, the First Epistle of Peter, and the First Epistle of John. According to some scholars, the Second Epistle of Peter explains that God is patient and has not yet brought about the Second Coming of Christ, in order that more people will have the chance to reject evil and find salvation (3:3–9); therefore, it calls on Christians to wait patiently for the Parousia and to study scripture. Other scholars, however, believe that the New Testament epistles are an exhortation to the early church believers to patiently expect the imminent return of Christ, predicted by Himself on several occasions in the gospels. The First Epistle of Clement, written by Pope Clement I in ca. 95, criticizes those who had doubts about the faith because the Second Coming had, in his view, not yet occurred.",

Futurists, who do not normally use the day-year principle, interpret the Prophecy of Seventy Weeks in Daniel 9:24 as years, just as historicists do. Most historicists have chosen timelines, from beginning to end, entirely in the past, but some, such as Adam Clarke, have timelines which also commenced with specific past events, but require a future fulfillment. In his commentary on Daniel 8:14 published in 1831, he stated that the 2,300-year period should be calculated from 334 BC, the year Alexander the Great began his conquest of the Persian Empire. His calculation resulted in the year 1966. He seems to have overlooked the fact that there is no \"year zero\" between BC and AD dates. For example, the year following 1 BC is 1 AD. Thus his calculations should have required an additional year, ending in 1967. He was not anticipating a literal regathering of the Jewish people prior to the second coming of Christ. But the date is of special significance to futurists since it is the year of Jerusalem's capture by Israeli forces during the Six-Day War.

And to her was granted that she should be arrayed in fine linen, clean and bright, for the fine linen is the righteous acts of the saints\" [Rev 19:7–8]. Christ is represented throughout Revelation as \"the Lamb\", symbolizing the giving of his life as an atoning sacrifice for the people of the world, just as lambs were sacrificed on the altar for the sins of Israel. His \"wife\" appears to represent the people of God, for she is dressed in the \"righteous acts of the saints\". As the marriage takes place, there is a great celebration in heaven which involves a \"great multitude\" [Rev 19:6].",

Although the doctrine of the resurrection comes to the forefront in the New Testament, it predates the Christian era. There is an apparent reference to the resurrection in the book of Job, where Job says, \"I know that my redeemer lives, and that he will stand at the latter day upon the earth. And though... worms destroy this body, yet in my flesh I will see God\" [Job 19:25–27]. Again, the prophet Daniel writes, \"Many of those who sleep in the dust of the earth shall awake, some to everlasting life, some to shame and everlasting contempt\" [Dan 12:2]. Isaiah says: \"Your dead will live. Together with my dead body, they will arise. Awake and sing, you who dwell in dust, for your dew is like the dew of herbs, and the earth will cast out the dead\" [Isa. 26:19].",

In this school of thought, the dead remain dead (and do not immediately progress to a Heaven, Hell, or Purgatory) until a physical resurrection of some or all of the dead occurs at the end of time. Some groups, Christadelphians in particular, consider that it is not a universal resurrection, and that at this time of resurrection that the Last Judgment will take place.",

"text": "Megiddo is mentioned twelve times in the Old Testament, ten times in reference to the ancient city of Megiddo, and twice with reference to \"the plain of Megiddo\", most probably simply meaning \"the plain next to the city\". None of these Old Testament passages describes the city of Megiddo as being associated with any particular prophetic beliefs. The one New Testament reference to the city of Armageddon found in Revelation 16:16 also makes no specific mention of any armies being predicted to one day gather in this city, but instead seems to predict only that \"they (will gather) the kings together to .... Armageddon\". The text does however seem to imply, based on the text from the earlier passage of Revelation 16:14, that the purpose of this gathering of kings in the \"place called Armageddon\" is \"for the war of the great day of God, the Almighty\". Because of the seemingly highly symbolic and even cryptic language of this one New Testament passage, some Christian scholars conclude that Mount Armageddon must be an idealized location. R. J. Rushdoony says, \"There are no mountains of Megiddo, only the Plains of Megiddo. This is a deliberate destruction of the vision of any literal reference to the place.\" Other scholars, including C. C. Torrey, Kline and Jordan argue that the word is derived from the Hebrew moed (מועד), meaning \"assembly\". Thus, \"Armageddon\" would mean \"Mountain of Assembly,\" which Jordan says is \"a reference to the assembly at Mount Sinai, and to its replacement, Mount Zion.\"",

Armageddon is the symbolic name given to this event based on scripture references regarding divine obliteration of God's enemies. The hermeneutical method supports this position by referencing Judges 4 and 5 where God miraculously destroys the enemy of His elect, Israel, at Megiddo, also called the Valley of Josaphat.",

] | Christian eschatology, is a major branch of study within Christian theology, deals with the doctrine of the "last things", especially the Second Coming of Christ, or Parousia. Eschatology – the word derives from two Greek roots meaning "last" (ἔσχατος) and "study" (-λογία) – involves the study of "end things", whether of the end of an individual life, of the end of the age, of the end of the world, or of the nature of the Kingdom of God. Broadly speaking, Christian eschatology focuses on the ultimate destiny of individual souls and of the entire created order, based primarily upon biblical texts within the Old and New Testaments. Christian eschatology looks to study and discuss matters such as death and the afterlife, Heaven and Hell, the Second Coming of Jesus, the resurrection of the dead, the rapture, the tribulation, millennialism, the end of the world, the Last Judgment, and the New Heaven and New Earth in the world to come. Eschatological passages appear in many places in the Bible, in both the Old and New Testaments. Many extra-biblical examples of eschatological prophecies also exist, as well as extra-biblical ecclesiastical traditions relating to the subject. | 2001-10-14T13:32:07Z | 2023-12-30T21:08:53Z | [

5,945 | Chicago White Sox | The Chicago White Sox are an American professional baseball team based in Chicago. The White Sox compete in Major League Baseball (MLB) as a member club of the American League (AL) Central division. The team is owned by Jerry Reinsdorf, and plays its home games at Guaranteed Rate Field, located on Chicago's South Side. The White Sox are one of two MLB teams based in Chicago, the other being the Chicago Cubs of the National League (NL) Central division.
One of the American League's eight charter franchises, the White Sox were established as a major league baseball club in 1901 as the Chicago White Stockings, before shortening their name to the White Sox in 1904. The team originally played their home games at South Side Park before moving to Comiskey Park in 1910, where they played until 1990. They moved into their current home, which was originally also known as Comiskey Park like its predecessor and later carried sponsorship from U.S. Cellular, for the 1991 season.
The White Sox won their first World Series, the 1906 World Series against the Cubs, with a defense-oriented team dubbed "the Hitless Wonders", and later won the 1917 World Series against the New York Giants. Their next appearance, the 1919 World Series, was marred by the Black Sox Scandal in which eight members of the White Sox were found to have conspired with gamblers to fix games and lose the World Series to the Cincinnati Reds. In response, the new Commissioner of Baseball, Kenesaw Mountain Landis, banned the players from the league for life. The White Sox have only made two World Series appearances since the scandal. The first came in 1959, where they lost to the Los Angeles Dodgers, before they finally won their third championship in 2005 against the Houston Astros. The 88 seasons it took the White Sox to win the World Series stands as the second longest MLB championship drought of all time, after the Cubs' 108 seasons.
From 1901 to 2023, the White Sox have an overall win-loss record of 9,553–9,491 (.502).
The White Sox originated as the Sioux City Cornhuskers of the Western League, a minor league under the parameters of the National Agreement with the National League. In 1894, Charles Comiskey bought the Cornhuskers and moved them to St. Paul, Minnesota, where they became the St. Paul Saints. In 1900, with the approval of Western League president Ban Johnson, Charles Comiskey moved the Saints into his hometown neighborhood of Armour Square, where they became the Chicago White Stockings, the former name of Chicago's National League team, the Orphans (now the Chicago Cubs).
In 1901, the Western League broke the National Agreement and became the new major league American League. The first season in the AL ended with a White Stockings championship. However, that would be the end of the season, as the World Series did not begin until 1903. The franchise, now known as the Chicago White Sox, made its first World Series appearance in 1906, beating the crosstown Cubs in six games.
The White Sox won a third pennant and a second World Series in 1917, beating the New York Giants in six games with help from stars Eddie Cicotte and "Shoeless" Joe Jackson. The Sox were heavily favored in the 1919 World Series, but lost to the Cincinnati Reds in eight games. Huge bets on the Reds fueled speculation that the series had been fixed. A criminal investigation went on in the 1920 season, and although all players were acquitted, commissioner Kenesaw Mountain Landis banned eight of them for life, in what was known as the Black Sox Scandal. This set the franchise back, as they did not win another pennant for 40 years.
The White Sox did not finish in the upper half of the American League again until after founder Charles Comiskey died and passed ownership of the club to his son, J. Louis Comiskey. They finished in the upper half most years between 1936 and 1946, under the leadership of manager Jimmy Dykes, with star shortstop Luke Appling (known as "Ol' Aches and Pains") and pitcher Ted Lyons, who both had their numbers 4 and 16 retired.
After J. Louis Comiskey died in 1939, ownership of the club was passed down to his widow, Grace Comiskey. The club was later passed down to Grace's children Dorothy and Chuck in 1956, with Dorothy selling a majority share to a group led by Bill Veeck after the 1958 season. Veeck was notorious for his promotional stunts, attracting fans to Comiskey Park with the new "exploding scoreboard" and outfield shower. In 1961, Arthur Allyn, Jr. briefly owned the club before selling to his brother John Allyn.
From 1951 to 1967, the White Sox had their longest period of sustained success, scoring a winning record for 17 straight seasons. Known as the "Go-Go White Sox" for their tendency to focus on speed and getting on base versus power hitting, they featured stars such as Minnie Miñoso, Nellie Fox, Luis Aparicio, Billy Pierce, and Sherm Lollar. From 1957 to 1965, the Sox were managed by Al López. The Sox finished in the upper half of the American League in eight of his nine seasons, including six years in the top two of the league. In 1959, the White Sox ended the New York Yankees' dominance over the American League, and won their first pennant since the ill-fated 1919 campaign. Despite winning game one of the 1959 World Series 11–0, they fell to the Los Angeles Dodgers in six games.
During the late 1960s and 1970s, the White Sox struggled to win games and attract fans. The team played a total of 20 home games at Milwaukee County Stadium in the 1968 and 1969 seasons. Allyn and Bud Selig agreed to a handshake deal that would give Selig control of the club and move them to Milwaukee, but it was blocked by the American League. Selig instead bought the Seattle Pilots and moved them to Milwaukee (where they would become the Milwaukee Brewers, putting enormous pressure on the American League to place a team in Seattle. A plan was in place for the Sox to move to Seattle and for Charlie Finley to move his Oakland A's to Chicago. However, the city had a renewed interest in the Sox after the 1972 season, and the American League instead added the expansion Seattle Mariners. The 1972 White Sox had the lone successful season of this era, as Dick Allen wound up winning the American League MVP award. Bill Veeck returned as owner of the Sox in 1975, and despite not having much money, they managed to win 90 games in 1977, with a team known as the "South Side Hitmen".
However, the team's fortunes plummeted afterwards, plagued by 90-loss teams and scarred by the notorious 1979 Disco Demolition Night promotion. Veeck was forced to sell the team, rejecting offers from ownership groups intent on moving the club to Denver and eventually agreeing to sell it to Ed DeBartolo, the only prospective owner who promised to keep the White Sox in Chicago. However, DeBartolo was rejected by the owners, and the club was then sold to a group headed by Jerry Reinsdorf and Eddie Einhorn. The Reinsdorf era started off well, with the team winning their first division title in 1983, led by manager Tony La Russa and stars Carlton Fisk, Tom Paciorek, Ron Kittle, Harold Baines, and LaMarr Hoyt. During the 1986 season, La Russa was fired by announcer-turned-general manager Ken Harrelson. La Russa went on to manage in six World Series (winning three) with the Oakland A's and St. Louis Cardinals, ending up in the Hall of Fame as the second-winningest manager of all time.
The White Sox struggled for the rest of the 1980s, as Chicago fought to keep them in town. Reinsdorf wanted to replace the aging Comiskey Park, and sought public funds to do so. When talks stalled, a strong offer was made to move the team to Tampa, Florida. Funding for a new ballpark was approved in an 11th-hour deal by the Illinois State Legislature on June 30, 1988, with the stipulation that it had to be built on the corner of 35th and Shields, across the street from the old ballpark, as opposed to the suburban ballpark the owners had designed. Architects offered to redesign the ballpark to a more "retro" feel that would fit in the city blocks around Comiskey Park; however, the ownership group was set on a 1991 open date, so they kept the old design. The new ballpark opened in 1991 under the name new Comiskey Park. The park, renamed in 2003 as U.S. Cellular Field and in 2016 as Guaranteed Rate Field, underwent many renovations in the early 2000s to give it a more retro feel.
The White Sox were fairly successful in the 1990s and early 2000s, with 12 winning seasons from 1990 to 2005. First baseman Frank Thomas became the face of the franchise, ending his career as the White Sox's all-time leader in runs, doubles, home runs, total bases, and walks. Other major players included Robin Ventura, Ozzie Guillén, Jack McDowell, and Bobby Thigpen. The Sox won the West division in 1993, and were in first place in 1994, when the season was canceled due to the 1994 MLB Strike.
In 2004, Ozzie Guillén was hired as manager of his former team. After finishing second in 2004, the Sox won 99 games and the Central Division title in 2005, behind the work of stars Paul Konerko, Mark Buehrle, A. J. Pierzynski, Joe Crede, and Orlando Hernández. They started the playoffs by sweeping the defending champion Boston Red Sox in the ALDS, and beat the Angels in five games to win their first pennant in 46 years, due to four complete games by the White Sox rotation. The White Sox went on to sweep the Houston Astros in the 2005 World Series, giving them their first World Championship in 88 years.
Guillén had marginal success during the rest of his tenure, with the Sox winning the Central Division title in 2008 after a one-game playoff with the Minnesota Twins. Guillén left the White Sox after the 2011 season and was replaced by former teammate Robin Ventura. The White Sox finished the 2015 season, their 115th in Chicago, with a 76–86 record, a three-game improvement over 2014. The White Sox recorded their 9,000th win in franchise history by the score of 3–2 against the Detroit Tigers on September 21, 2015. Ventura returned in 2016, with a young core featuring José Abreu, Adam Eaton, José Quintana, and Chris Sale. Ventura resigned after the 2016 season, in which the White Sox finished 78–84. Rick Renteria, the 2016 White Sox bench coach, was promoted to the role of manager.
Prior to the start of the 2017 season, the White Sox traded Sale to the Boston Red Sox and Eaton to the Washington Nationals for prospects including Yoán Moncada, Lucas Giolito and Michael Kopech, signaling the beginning of a rebuilding period. During the 2017 season, the White Sox continued their rebuild when they made a blockbuster trade with their crosstown rival, the Chicago Cubs, in a swap that featured the Sox sending pitcher José Quintana to the Cubs in exchange for four prospects headlined by outfielder Eloy Jiménez and pitcher Dylan Cease. This was the first trade between the White Sox and Cubs since the 2006 season.
During the 2018 season, relief pitcher Danny Farquhar suffered a brain hemorrhage while he was in the dugout between innings. Farquhar remained out of action for the rest of the season and just recently got medically cleared to return to baseball, despite some doctors doubting that he would make a full recovery. Also occurring during the 2018 season, the White Sox announced that the club would be the first Major League Baseball team to entirely discontinue use of plastic straws, in ordinance with the "Shedd the Straw" campaign by Shedd Aquarium. The White Sox broke an MLB record during their 100-loss campaign of 2018, but broke the single-season strikeout record in only a year after the Milwaukee Brewers broke the record in the 2017 season. On December 3, 2018, head trainer Herm Schneider retired after 40 seasons with the team; his new role will be as an advisor on medical issues pertaining to free agency, the amateur draft and player acquisition. Schneider will also continue to be a resource for the White Sox training department, including both the major and minor league levels.
On August 25, 2020, Lucas Giolito recorded the 19th no-hitter in White Sox history, and the first since Philip Humber's Perfect Game in 2012. Giolito struck out 13 and threw 74 of 101 pitches for strikes. He only allowed one baserunner, which was a walk to Erik González in the fourth inning. In 2020, the White Sox clinched a playoff berth for the first time since 2008, with a record 35–25 in the pandemic-shortened season, but lost to the Oakland Athletics in three games during the Wild Card Series. The White Sox also made MLB history by being the first team to go undefeated against left-handed pitching, with a 14–0 record. At the end of the season, Renteria and longtime pitching coach Don Cooper were both fired. Jose Abreu became the 4th different White Sox player to win the AL MVP joining Dick Allen, Nellie Fox, and Frank Thomas. During the 2021 offseason, the White Sox brought back Tony La Russa as their manager for 2021. At the age of 76 when hired, La Russa became the oldest active manager in MLB.
On April 14, 2021, Carlos Rodon recorded the teams' 20th no-hitter against the Cleveland Indians. Rodon retired the first 25 batters he faced and was saved by an incredible play at first base by first baseman Jose Abreu to get the first out in the 9th before hitting Roberto Pérez which was the only baserunner Rodon allowed. Rodon struck out seven and threw 75 of 114 pitches for strikes. On June 6, 2021, the White Sox beat the Detroit Tigers 3–0. This also had Tony La Russa winning his 2,764th game as manager passing John McGraw for 2nd on the all time managerial wins list. On August 12, 2021, the White Sox faced New York Yankees in the first ever Field of Dreams game in Dyersville, Iowa. The White Sox won the game 9–8 on a walk-off two run Home Run by Tim Anderson. The homer was the 15th walk-off home run against the Yankees in White Sox history; the first being Shoeless Joe Jackson on July 20, 1919, whose character featured in the movie Field of Dreams. On September 23, 2021, the White Sox clinched the American League Central Division for the first time since 2008 against the Cleveland Indians.
In the late 1980s, the franchise threatened to relocate to Tampa Bay (as did the San Francisco Giants), but frantic lobbying on the part of the Illinois governor James R. Thompson and state legislature resulted in approval (by one vote) of public funding for a new stadium. Designed primarily as a baseball stadium (as opposed to a "multipurpose" stadium), the new Comiskey Park (redubbed U.S. Cellular Field in 2003 and Guaranteed Rate Field in 2016) was built in a 1960s style, similar to Dodger Stadium and Kauffman Stadium. There were ideas for other stadium designs submitted to bring a more neighborhood feel, but ultimately they were not selected. The park opened in 1991 to positive reaction, with many praising its wide-open concourses, excellent sight lines, and natural grass (unlike other stadiums of the era, such as Rogers Centre in Toronto). The park's inaugural season drew 2,934,154 fans — at the time, an all-time attendance record for any Chicago baseball team.
In recent years, money accrued from the sale of naming rights to the field has been allocated for renovations to make the park more aesthetically appealing and fan-friendly. Notable renovations of early phases included reorientation of the bullpens parallel to the field of play (thus decreasing slightly the formerly symmetrical dimensions of the outfield); filling seats in up to and shortening the outfield wall; ballooning foul-line seat sections out toward the field of play; creating a new multitiered batter's eye, allowing fans to see out through one-way screens from the center-field vantage point, and complete with concession stand and bar-style seating on its "fan deck"; and renovating all concourse areas with brick, historic murals, and new concession stand ornaments to establish a more friendly feel. The stadium's steel and concrete were repainted dark gray and black. In 2016, the scoreboard jumbotron was replaced with a new Mitsubishi Diamondvision HDTV screen.
The top quarter of the upper deck was removed in 2004, and a black wrought-metal roof was placed over it, covering all but the first eight rows of seats. This decreased seating capacity from 47,098 to 40,615; 2005 also had the introduction of the Scout Seats, redesignating (and reupholstering) 200 lower-deck seats behind home plate as an exclusive area, with seat-side waitstaff and a complete restaurant located underneath the concourse. The most significant structural addition besides the new roof was 2005's FUNdamentals Deck, a multitiered structure on the left-field concourse containing batting cages, a small Tee Ball field, speed pitch, and several other children's activities intended to entertain and educate young fans with the help of coaching staff from the Chicago Bulls/Sox Training Academy. This structure was used during the 2005 American League playoffs by ESPN and the Fox Broadcasting Company as a broadcasting platform.
Designed as a seven-phase plan, the renovations were completed before the 2007 season with the seventh and final phase. The most visible renovation in this final phase was replacing the original blue seats with green seats. The upper deck already had new green seats put in before the beginning of the 2006 season. Beginning with the 2007 season, a new luxury-seating section was added in the former press box. This section has amenities similar to those of the Scout Seats section. After the 2007 season, the ballpark continued renovation projects despite the phases being complete. In July 2019, the White Sox extended the netting to the foul pole.
The St. Paul Saints first played their games at Lexington Park. When they moved to Chicago's Armour Square neighborhood, they began play at the South Side Park. Previously a cricket ground, the park was located on the north side of 39th Street (now called Pershing Road) between South Wentworth and South Princeton Avenues. Its massive dimensions yielded few home runs, which was to the advantage of the White Sox's Hitless Wonders teams of the early 20th century.
After the 1909 season, the Sox moved five blocks to the north to play in the new Comiskey Park, while the 39th Street grounds became the home of the Chicago American Giants of the Negro leagues. Billed as the Baseball Palace of the World, it originally held 28,000 seats and eventually grew to hold over 50,000. It became known for its many odd features, such as the outdoor shower and the exploding scoreboard. When it closed after the 1990 season, it was the oldest ballpark still in Major League Baseball.
The White Sox have held spring training in:
On November 19, 2007, the cities of Glendale and Phoenix, Arizona, broke ground on the Cactus League's newest spring-training facility. Camelback Ranch, the $76 million, two-team facility, is the new home of both the White Sox and the Los Angeles Dodgers for their spring training. Aside from state-of-the-art baseball facilities at the 10,000-seat stadium, the location includes residential, restaurant and retail development, a four-star hotel, and an 18-hole golf course. Other amenities include 118,000 sq ft (11,000 m) of major and minor league clubhouses for the two teams, four major league practice fields, eight minor league practice fields, two practice infields, and parking to accommodate 5,000 vehicles.
Over the years, the White Sox have become noted for many of their uniform innovations and changes. In 1960, they became the first team in the major sports to put players' last names on jerseys for identification purposes.
In 1912, the White Sox debuted a large "S" in a Roman-style font, with a small "O" inside the top loop of the "S" and a small "X" inside the bottom loop. This is the logo associated with the 1917 World Series championship team and the 1919 Black Sox. With a couple of brief interruptions, the dark-blue logo with the large "S" lasted through 1938 (but continued in a modified block style into the 1940s). Through the 1940s, the White Sox team colors were primarily navy blue trimmed with red.
The White Sox logo in the 1950s and 1960s (actually beginning in the 1949 season) was the word "SOX" in Gothic script, diagonally arranged, with the "S" larger than the other two letters. From 1949 through 1963, the primary color was black (trimmed with red after 1951). This is the logo associated with the Go-Go Sox era.
In 1964, the primary color went back to navy blue, and the road uniforms changed from gray to pale blue. In 1971, the team's primary color changed from royal blue to red, with the color of their pinstripes and caps changing to red. The 1971–1975 uniform included red socks.
In 1976, the team's uniforms changed again. The team's primary color changed back from red to navy. The team based their uniforms on a style worn in the early days of the franchise, with white jerseys worn at home, and blue on the road. The team brought back white socks for the last time in team history. The socks featured a different stripe pattern every year. The team also had the option to wear blue or white pants with either jersey. Additionally, the team's "SOX" logo was changed to a modern-looking "SOX" in a bold font, with "CHICAGO" written across the jersey. Finally, the team's logo featured a silhouette of a batter over the words "SOX".
The new uniforms also featured collars and were designed to be worn untucked — both unprecedented. Yet by far, the most unusual wrinkle was the option to wear shorts, which the White Sox did for the first game of a doubleheader against the Kansas City Royals in 1976. The Hollywood Stars of the Pacific Coast League had previously tried the same concept, but it was also poorly received. Apart from aesthetic issues, as a practical matter, shorts are not conducive to sliding, due to the likelihood of significant abrasions.
Upon taking over the team in 1980, new owners Eddie Einhorn and Jerry Reinsdorf announced a contest where fans were invited to create new uniforms for the White Sox. The winning entries, submitted by a fan, had the word "SOX" written across the front of the jersey in the same font as the cap, inside of a large blue stripe trimmed with red. The red and blue stripes were also on the sleeves, and the road jerseys were gray to the home whites. In those jerseys, the White Sox won 99 games and the AL West championship in 1983, the best record in the majors.
After five years, those uniforms were retired and replaced with a more basic uniform that had "White Sox" written across the front in script, with "Chicago" on the front of the road jersey. The cap logo was also changed to a cursive "C", although the batter logo was retained for several years.
For a midseason 1990 game at Comiskey Park, the White Sox appeared once in a uniform based on that of the 1917 White Sox. They then switched their regular uniform style once more. In September, for the final series at the old Comiskey Park, the White Sox rolled out a new logo, a simplified version of the 1949–63 Gothic "SOX" logo. They also introduced a uniform with black pinstripes, also similar to the Go-Go Sox era uniform. The team's primary color changed back to black, this time with silver trim. The team also introduced a new sock logo—a white silhouette of a sock centered inside a white outline of a baseball diamond—which appeared as a sleeve patch on the away uniform until 2010 (switched to the "SOX" logo in 2011), and on the alternate black uniform since 1993. With minor modifications (i.e., occasionally wearing vests, black game jerseys), the White Sox have used this style ever since.
During the 2012 and 2013 seasons, the White Sox wore their throwback uniforms at home every Sunday, starting with the 1972 red-pinstriped throwback jerseys worn during the 2012 season, followed by the 1982–86 uniforms the next season. In the 2014 season, the "Winning Ugly" throwbacks were promoted to full-time alternate status, and are now worn at home on Sundays. In one game during the 2014 season, the Sox paired their throwbacks with a cap featuring the batter logo instead of the wordmark "SOX"; this is currently their batting-practice cap prior to games in the throwback uniforms.
In 2021, to commemorate the Field of Dreams game, the White Sox wore special uniforms honoring the 1919 team. That same year, the White Sox wore "City Connect" alternate uniforms introduced by Nike, featuring an all-black design with silver pinstripes, and "Southside" wordmark in front.
Note: American League Championship Series began in 1969
The White Sox have retired a total of 12 jersey numbers: 11 worn by former White Sox and number 42 in honor of Jackie Robinson.
Luis Aparicio's No. 11 was issued at his request for 11-time Gold Glove winner shortstop Omar Vizquel (because No. 13 was used by manager Ozzie Guillén; Vizquel, like Aparicio and Guillen, play(ed) shortstop and all share a common Venezuelan heritage). Vizquel played for team in 2010 and 2011.
Also, Harold Baines had his No. 3 retired in 1989; it has since been 'unretired' 3 times in each of his subsequent returns.
The White Sox were originally known as the White Stockings, a reference to the original name of the Chicago Cubs. To fit the name in headlines, local newspapers such as the Chicago Tribune abbreviated the name alternatively to Stox and Sox. Charles Comiskey would officially adopt the White Sox nickname in the club's first years, making them the first team to officially use the "Sox" name. The Chicago White Sox are most prominently nicknamed "the South Siders", based on their particular district within Chicago. Other nicknames include the synonymous "Pale Hose"; "the ChiSox", a combination of "Chicago" and "Sox", used mostly by the national media to differentiate them between the Boston Red Sox (BoSox); and "the Good Guys", a reference to the team's one-time motto "Good guys wear black", coined by broadcaster Ken Harrelson. Most fans and Chicago media refer to the team as simply "the Sox". The Spanish language media sometimes refer to the team as Medias Blancas for "White Socks."
Several individual White Sox teams have received nicknames over the years:
From 1961 until 1991, lifelong Chicago resident Andrew Rozdilsky performed as the unofficial yet popular mascot "Andy the Clown" for the White Sox at the original Comiskey Park. Known for his elongated "Come on you White Sox" battle cry, Andy got his start after a group of friends invited him to a Sox game in 1960, where he decided to wear his clown costume and entertain fans in his section. That response was so positive that when he won free 1961 season tickets, he decided to wear his costume to all games. Comiskey Park ushers eventually offered free admission to Rozdilsky. Starting in 1981, the new ownership group led by Jerry Reinsdorf introduced a twosome, called Ribbie and Roobarb, as the official team mascots, and banned Rozdilsky from performing in the lower seating level. Ribbie and Roobarb were very unpopular, as they were seen as an attempt to get rid of the beloved Andy the Clown.
In 1988, the Sox got rid of Ribbie and Roobarb; Andy the Clown was not permitted to perform in the new Comiskey Park when it opened in 1991. In the early 1990s, the White Sox had a cartoon mascot named Waldo the White Sox Wolf that advertised the "Silver and Black Pack", the team's kids' club at the time. The team's current mascot, SouthPaw, was introduced in 2004 to attract young fans.
Nancy Faust became the White Sox organist in 1970, a position she held for 40 years. She was one of the first ballpark organists to play pop music, and became known for her songs playing on the names of opposing players (such as Iron Butterfly's "In-A-Gadda-Da-Vida" for Pete Incaviglia). Her many years with the White Sox established her as one of the last great stadium organists. Since 2011, Lori Moreland has served as the White Sox organist.
Similar to the Boston Red Sox with "Sweet Caroline" (and two songs named "Tessie"), and the New York Yankees with "Theme from New York, New York", several songs have become associated with the White Sox over the years. They include:
The Chicago Cubs are the crosstown rivals of the White Sox, a rivalry that some made fun of prior to the White Sox's 2005 title because both of them had extremely long championship droughts. The nature of the rivalry is unique; with the exception of the 1906 World Series, in which the White Sox upset the favored Cubs, the teams never met in an official game until 1997, when interleague play was introduced. In the intervening time, the two teams sometimes met for exhibition games. The White Sox currently led the regular-season series 48–39, winning the last four seasons in a row. The BP Crosstown Cup was introduced in 2010 and the White Sox won the first three seasons (2010-2012) until the Cubs first won the Cup in 2013 by sweeping the season series. The White Sox won the Cup the next season and retained the Cup the following two years (series was a tie - Cup remains with defending team in the event of a tie). The Cubs took back the Cup in 2017. Two series sweeps have occurred since interleague play began, both by the Cubs in 1998 and 2013.
An example of this volatile rivalry is the game played between the White Sox and the Cubs at U.S. Cellular Field on May 20, 2006. White Sox catcher A. J. Pierzynski was running home on a sacrifice fly by center fielder Brian Anderson and smashed into Cubs catcher Michael Barrett, who was blocking home plate. Pierzynski lost his helmet in the collision, and slapped the plate as he rose. Barrett stopped him, and after exchanging a few words, punched Pierzynski in the face, causing a melee to ensue. Brian Anderson and Cubs first baseman John Mabry got involved in a separate confrontation, although Mabry was later determined to be attempting to be a peacemaker. After 10 minutes of conferring following the fight, the umpires ejected Pierzynski, Barrett, Anderson, and Mabry. As Pierzynski entered his dugout, he pumped his arms, causing the sold-out crowd at U.S. Cellular Field to erupt in cheers. When play resumed, White Sox second baseman Tadahito Iguchi blasted a grand slam to put the White Sox up 5–0 on their way to a 7–0 win over their crosstown rivals. While other major league cities and metropolitan areas have two teams co-exist, all of the others feature at least one team that began playing there in 1961 or later, whereas the White Sox and Cubs have been competing for their city's fans since 1901.
A historical regional rival was the St. Louis Browns. Through the 1953 season, the two teams were located fairly close to each other (including the 1901 season when the Browns were the Milwaukee Brewers), and could have been seen as the American League equivalent of the Cardinals–Cubs rivalry, being that Chicago and St. Louis have for years been connected by the same highway (U.S. Route 66 and now Interstate 55). The rivalry has been somewhat revived at times in the past, involving the Browns' current identity, the Baltimore Orioles, most notably in 1983.
The current Milwaukee Brewers franchise were arguably the White Sox's main and biggest rival, due to the proximity of the two cities (resulting in large numbers of White Sox fans who would regularly be in attendance at the Brewers' former home, Milwaukee County Stadium), and with the teams competing in the same American League division for the 1970 and 1971 seasons and then again from 1994 to 1997. The rivalry has since cooled off, however, when the Brewers moved to the National League in 1998. However, with the start of the 2023 season, all teams will play each other at least once a year, leading to the Brewers-White Sox series to return on a yearly basis.
The rivalry between the White Sox and Minnesota Twins developed during the 2000s, as the two teams consistently battled for the AL Central Crown. The Twins won the division in 2002, 2003, 2004, 2006, and 2009, with the Sox winning in 2000, 2005, and 2008, many of those years their rival was the division runner-up. The teams met in the 2008 American League Central tie-breaker game, which was necessitated by the two clubs finishing the season with identical records. The White Sox won this game 1–0 on a Jim Thome home run. The rivalry re-emerged in the 2020s, with the Twins winning the AL Central in 2020 by a single game over the White Sox and Cleveland Indians, and the Sox and Twins have continued to compete for the division title since that point.
The series between the White Sox and Detroit Tigers is one of the oldest active rivalries in the league today. Both teams joined the American League in 1901 after being charter members of the original Western League. Both have actively played one another annually for over 120 seasons. As is often the case between professional sports teams located Chicago or Detroit; there usually exists a rivalry as such with the Bulls-Pistons rivalry of the NBA. Despite playing one another for over 2,200 games; both teams have yet to meet in the postseason in their 122-year series.
In 1990, then new White Sox owners Eddie Einhorn and Jerry Reinsdorf began Chicago White Sox Charities, a 501(c) (3) charitable organization that is the team's philanthropic arm, donating over $27 million over time to a plethora of Chicago organizations. White Sox Charities began centering on early childhood literacy programs, then expanded to focusing on encouraging high school graduation and college matriculation so the team can monitor its success. It also supports children at risk as well as promotes wellness and health.
The White Sox did not sell exclusive rights for radio broadcasts from radio's inception until 1944, instead having local stations share rights for games, and after WGN (720) was forced to abdicate their rights to the team in the 1943 after 16 seasons due to children's programming commitments from their network, Mutual. The White Sox first granted exclusive rights in 1944, and bounced between stations until 1952, when they started having all games broadcast on WCFL (1000). Throughout this period of instability, one thing remained constant, the White Sox play-by-play announcer, Bob Elson. Known as the "Commander", Elson was the voice of the Sox from 1929 until his departure from the club in 1970. In 1979, he was the recipient of the Ford Frick Award, and his profile is permanently on display in the National Baseball Hall of Fame.
After the 1966 season, radio rights shifted from WCFL to WMAQ (670). An NBC-owned and -operated station until 1988 when Westinghouse Broadcasting purchased it after NBC's withdrawal from radio, it was the home of the Sox until the 1996 season, outside of a team nadir in the early '70s, where it was forced to broker time on suburban La Grange's WTAQ (1300) and Evanston's WEAW-FM (105.1) to have their play-by-play air in some form (though WEAW transmitted from the John Hancock Center, FM radio was not established as a band for sports play-by-play at the time), and a one-season contract on WBBM (780) in 1981. After Elson's retirement in 1970, Harry Caray began his tenure as the voice of the White Sox, on radio and on television. Although best remembered as a broadcaster for the rival Cubs, Caray was very popular with White Sox fans, pining for a "cold one" during broadcasts. Caray often broadcast from the stands, sitting at a table set up amid the bleachers. It became a badge of honor among Sox fans to "Buy Harry a beer..." By game's end, one would see a large stack of empty beer cups beside his microphone. This only endeared him to fans that much more. In fact, he started his tradition of leading the fans in the singing of "Take Me Out To The Ballgame" with the Sox. Caray, alongside color analyst Jimmy Piersall, was never afraid to criticize the Sox, which angered numerous Sox managers and players, notably Bill Melton and Chuck Tanner. He left to succeed Jack Brickhouse as the voice of the Cubs in 1981, where he became a national icon.
The White Sox shifted through several announcers in the 1980s, before hiring John Rooney as play-by-play announcer in 1989. In 1992, he was paired with color announcer Ed Farmer. In 14 seasons together, the duo became a highly celebrated announcing team, even being ranked by USA Today as the top broadcasting team in the American League. Starting with Rooney and Farmer's fifth season together, Sox games returned to the 1000 AM frequency for the first time in 30 years (now the ESPN owned and operated station WMVP). The last game on WMVP was game 4 of the 2005 World Series, with the White Sox clinching their first World Series title in 88 years. That also was Rooney's last game with the Sox, as he left to join the radio broadcast team of the St. Louis Cardinals.
In 2006, radio broadcasts returned to 670 AM, this time on the sports radio station WSCR owned by CBS Radio (WSCR took over the 670 frequency in August 2000 as part of a number of shifts among CBS Radio properties to meet market ownership caps). Ed Farmer became the play-by-play man after Rooney left, joined in the booth by Chris Singleton from 2006 to 2007 and then Steve Stone in 2008. In 2009, Darrin Jackson became the color announcer for White Sox radio, where he remains today. Farmer and Jackson were joined by pregame/postgame host Chris Rogney.
The Chicago White Sox Radio Network currently has 18 affiliates in three states. As of recently, White Sox games are also broadcast in Spanish with play-by-play announcer Hector Molina joined in the booth by Billy Russo. Formerly broadcasting on ESPN Deportes Radio via WNUA, games are now broadcast in Spanish on WRTO (1200).
In the 2016 season, the play-by-play rights shifted to Cumulus Media's WLS (890) under a five-year deal, when WSCR acquired the rights to Cubs games after a one-year period on WBBM. However, by all counts, the deal was a disaster for the White Sox, as WLS's declining conservative talk format, associated ratings, and management/personnel issues (including said hosts barely promoting the team and its games), and a signal that is weak in the northern suburbs and into Wisconsin, was not a good fit for the team. Cumulus also had voluminous financial issues, and by the start of 2018, looked to both file Chapter 11 bankruptcy and restructure their play-by-play deals or depart them, both with local teams and nationally through their Westwood One/NFL deal.
The White Sox and Tribune Broadcasting (which has since merged with Nexstar Media Group) then announced a three-year deal for WGN Radio to become the White Sox flagship as of February 14, 2018, just in time for spring training. Ed Farmer and Darrin Jackson continued to be on play-by-play, with Andy Masur taking over pregame/postgame duties. Ed Farmer died suddenly on April 1, 2020, a long-term battle with polycystic kidney disease, but the team waited to announce his successor due to the COVID-19 pandemic and the uncertainty of the 2020 season going forward. On June 30 with the season's structure announced, Masur was confirmed as Farmer's successor for the season.
Under Nexstar's new management, WGN decided to pursue a thriftier programming direction, and made no moves to renew the deal at the end of the 2020 season. The team thus returned to WMVP (now managed by Good Karma Brands, which also owns Brewers flagship WTMJ) for a multi-year agreement to start with the 2021 season. In a surprising turn of events, WMVP and the team announced on December 4, 2020, that Len Kasper, the longtime television play-by-play voice of the Cubs, would move to the South Side and become the radio play-by-play voice of the White Sox. The agreement has flexibility which allows Kasper to do some television games on NBC Sports Chicago on days when Jason Benetti has other national commitments.
White Sox games appeared sporadically on television throughout the first half of the 20th century, most commonly announced by Jack Brickhouse on WGN-TV (channel 9). Starting in 1968, Jack Drees took play-by-play duties as the Sox were broadcast on WFLD (channel 32). After 1972, Harry Caray (joined by Jimmy Piersall in 1977) began double duty as a TV and radio announcer for the Sox, as broadcasts were moved to channel 44, WSNS-TV, from 1972 to 1980, followed by one year on WGN-TV.
Don Drysdale became the play-by-play announcer in 1982, as the White Sox began splitting their broadcasts between WFLD and the new regional cable television network, Sportsvision. Ahead of its time, Sportsvision had a chance to gain huge profits for the Sox. However, few people would subscribe to the channel after being used to free-to-air broadcasts for many years, along with Sportsvision being stunted by the city of Chicago's wiring for cable television taking much longer than many markets because of it being an area where over-the-air subscription services were still more popular, resulting in the franchise losing around $300,000 a month. While this was going on, every Cubs game was on WGN, with Harry Caray becoming the national icon he never was with the White Sox. The relatively easy near-national access to Cubs games versus Sox games in this era, combined with the popularity of Caray and the Cubs being owned by the Tribune Company, is said by some to be the main cause of the Cubs' advantage in popularity over the Sox.
Three major changes to White Sox broadcasting occurred in 1989-1991: in 1989, with the city finally fully wired for cable service, Sportsvision was replaced by SportsChannel Chicago (itself eventually turning into Fox Sports Net Chicago), which varied over its early years as a premium sports service and basic cable channel. In 1990, over-the-air broadcasts shifted back to WGN. And in 1991, Ken Harrelson became the play-by-play announcer of the White Sox. One of the most polarizing figures in baseball, "Hawk" has been both adored and scorned for his emotive announcing style. His history of calling out umpires has earned him reprimands from the MLB commissioner's office, and he has been said to be the most biased announcer in baseball. However, Harrelson has said that he is proud of being "the biggest homer in baseball", saying that he is a White Sox fan like his viewers. The team moved from FSN Chicago to the newly launched NBC Sports Chicago in March 2005, as Jerry Reinsdorf looked to control the rights for his team rather than sell rights to another party; Reinsdorf holds a 40% interest in the network, with 20% of that interest directly owned by the White Sox corporation.
Previously, White Sox local television broadcasts were split between two channels: the majority of games were broadcast on cable by NBC Sports Chicago, and remaining games were produced by WGN Sports and were broadcast locally on WGN-TV. WGN games were also occasionally picked up by local stations in Illinois, Iowa, and Indiana. In the past, WGN games were broadcast nationally on the WGN America superstation, but those broadcasts ended after the 2014 season as WGN America began its transition to a standard cable network. WGN Sports-produced White Sox games not carried by WGN-TV were carried by WCIU-TV (channel 26) until the 2015 season, when they moved to MyNetworkTV station WPWR (channel 50). That arrangement ended on September 1, 2016, when WGN became an independent station.
Prior to 2016, the announcers were the same no matter where the games were broadcast: Harrelson provided play-by-play, and Steve Stone provided color analysis since 2009. Games that are broadcast on NBC Sports Chicago feature pregame and postgame shows, hosted by Chuck Garfein with analysis from Bill Melton and occasionally Frank Thomas. In 2016, the team announced an official split of the play-by-play duties, with Harrelson calling road games and the Crosstown Series and Jason Benetti calling home games. In 2017, the team announced that the 2018 season will be Harrelson's final in the booth. He will call 20 games over the course of the season, after which Benetti will take over full-time play-by-play duties.
On January 2, 2019, the White Sox (along with the Chicago Bulls and Chicago Blackhawks) agreed to an exclusive multiyear deal with NBC Sports Chicago, ending the team's broadcasts on WGN-TV following the 2019 season.
The Chicago White Sox farm system consists of six minor league affiliates.
Silver Chalice is a digital and media investment subsidiary of the White Sox with Brooks Boyer as CEO.
Silver Chalice was co-founded by Jerry Reinsdorf, White Sox executive Brooks Boyer, Jason Coyle and John Burris in 2009. Chalice has since partnered with IMG on Campus Insiders, a college sports digital channel. The company also invested in 120 Sports, a digital sports channel, that launched in June 2016. These efforts have since been merged with Sinclair Broadcasting Group's American Sports Network into the new multi-platform network Stadium as of September 2017. | [

The team also introduced a new sock logo—a white silhouette of a sock centered inside a white outline of a baseball diamond—which appeared as a sleeve patch on the away uniform until 2010 (switched to the \"SOX\" logo in 2011), and on the alternate black uniform since 1993. With minor modifications (i.e., occasionally wearing vests, black game jerseys), the White Sox have used this style ever since.",

As Pierzynski entered his dugout, he pumped his arms, causing the sold-out crowd at U.S. Cellular Field to erupt in cheers.

] | The Chicago White Sox are an American professional baseball team based in Chicago. The White Sox compete in Major League Baseball (MLB) as a member club of the American League (AL) Central division. The team is owned by Jerry Reinsdorf, and plays its home games at Guaranteed Rate Field, located on Chicago's South Side. The White Sox are one of two MLB teams based in Chicago, the other being the Chicago Cubs of the National League (NL) Central division. One of the American League's eight charter franchises, the White Sox were established as a major league baseball club in 1901 as the Chicago White Stockings, before shortening their name to the White Sox in 1904. The team originally played their home games at South Side Park before moving to Comiskey Park in 1910, where they played until 1990. They moved into their current home, which was originally also known as Comiskey Park like its predecessor and later carried sponsorship from U.S. Cellular, for the 1991 season. The White Sox won their first World Series, the 1906 World Series against the Cubs, with a defense-oriented team dubbed "the Hitless Wonders", and later won the 1917 World Series against the New York Giants. Their next appearance, the 1919 World Series, was marred by the Black Sox Scandal in which eight members of the White Sox were found to have conspired with gamblers to fix games and lose the World Series to the Cincinnati Reds. In response, the new Commissioner of Baseball, Kenesaw Mountain Landis, banned the players from the league for life. The White Sox have only made two World Series appearances since the scandal. The first came in 1959, where they lost to the Los Angeles Dodgers, before they finally won their third championship in 2005 against the Houston Astros. The 88 seasons it took the White Sox to win the World Series stands as the second longest MLB championship drought of all time, after the Cubs' 108 seasons. From 1901 to 2023, the White Sox have an overall win-loss record of 9,553–9,491 (.502). | 2001-10-30T16:21:35Z | 2023-12-26T16:23:37Z | [

5,946 | Casuistry | In ethics, casuistry (/ˈkæzjuɪstri/ KAZ-ew-iss-tree) is a process of reasoning that seeks to resolve moral problems by extracting or extending abstract rules from a particular case, and reapplying those rules to new instances. This method occurs in applied ethics and jurisprudence. The term is also used pejoratively to criticise the use of clever but unsound reasoning, especially in relation to moral questions as in sophistry). It has been defined as follows:
Study of cases of conscience and a method of solving conflicts of obligations by applying general principles of ethics, religion, and moral theology to particular and concrete cases of human conduct. This frequently demands an extensive knowledge of natural law and equity, civil law, ecclesiastical precepts, and an exceptional skill in interpreting these various norms of conduct....
It remains a common method in applied ethics.
According to the Online Etymological Dictionary, the term and its agent noun "casuist", appearing from about 1600, derive from the Latin noun casus, meaning "case", especially as referring to a "case of conscience". The same source says, "Even in the earliest printed uses the sense was pejorative".
Casuistry dates from Aristotle (384–322 BC), yet the peak of casuistry was from 1550 to 1650, when the Society of Jesus used case-based reasoning, particularly in administering the Sacrament of Penance (or "confession"). The term became pejorative following Blaise Pascal's attack on the misuse of the method in his Provincial Letters (1656–57). The French mathematician, religious philosopher and Jansenist sympathiser attacked priests who used casuistic reasoning in confession to pacify wealthy church donors. Pascal charged that "remorseful" aristocrats could confess a sin one day, re-commit it the next, then generously donate to the church and return to re-confess their sin, confident that they were being assigned a penance in name only. These criticisms darkened casuistry's reputation in the following centuries. For example, the Oxford English Dictionary quotes a 1738 essay by Henry St. John, 1st Viscount Bolingbroke to the effect that casuistry "destroys, by distinctions and exceptions, all morality, and effaces the essential difference between right and wrong, good and evil"
The 20th century saw a revival of interest in casuistry. In their book The Abuse of Casuistry: A History of Moral Reasoning (1988), Albert Jonsen and Stephen Toulmin argue that it is not casuistry but its abuse that has been a problem; that, properly used, casuistry is powerful reasoning. Jonsen and Toulmin offer casuistry as a method for compromising the contradictory principles of moral absolutism and moral relativism. In addition, the ethical philosophies of utilitarianism (especially preference utilitarianism) and pragmatism have been identified as employing casuistic reasoning.
The casuistic method was popular among Catholic thinkers in the early modern period. Casuistic authors include Antonio Escobar y Mendoza, whose Summula casuum conscientiae (1627) enjoyed great success, Thomas Sanchez, Vincenzo Filliucci (Jesuit and penitentiary at St Peter's), Antonino Diana, Paul Laymann (Theologia Moralis, 1625), John Azor (Institutiones Morales, 1600), Etienne Bauny, Louis Cellot, Valerius Reginaldus, and Hermann Busembaum (d. 1668).
The progress of casuistry was interrupted toward the middle of the 17th century by the controversy which arose concerning the doctrine of probabilism, which effectively stated that one could choose to follow a "probable opinion", that is, supported by a theologian or another, even if it contradicted a more probable opinion or a quotation from one of the Fathers of the Church.
Certain kinds of casuistry were criticised by early Protestant theologians, because it was used to justify many of the abuses that they sought to reform. It was famously attacked by the Catholic and Jansenist philosopher Blaise Pascal, during the formulary controversy against the Jesuits, in his Provincial Letters as the use of rhetorics to justify moral laxity, which became identified by the public with Jesuitism; hence the everyday use of the term to mean complex and sophistic reasoning to justify moral laxity. By the mid-18th century, "casuistry" had become a synonym for attractive-sounding, but ultimately false, moral reasoning.
In 1679 Pope Innocent XI publicly condemned sixty-five of the more radical propositions (stricti mentalis), taken chiefly from the writings of Escobar, Suarez and other casuists as propositiones laxorum moralistarum and forbade anyone to teach them under penalty of excommunication. Despite this condemnation by a pope, both Catholicism and Protestantism permit the use of ambiguous statements in specific circumstances.
G. E. Moore dealt with casuistry in chapter 1.4 of his Principia Ethica, in which he claims that "the defects of casuistry are not defects of principle; no objection can be taken to its aim and object. It has failed only because it is far too difficult a subject to be treated adequately in our present state of knowledge". Furthermore, he asserted that "casuistry is the goal of ethical investigation. It cannot be safely attempted at the beginning of our studies, but only at the end".
Since the 1960s, applied ethics has revived the ideas of casuistry in applying moral reasoning to particular cases in law, bioethics, and business ethics, so casuistry's reputation is somewhat better now.
Pope Francis, a Jesuit, has criticized casuistry as "the practice of setting general laws on the basis of exceptional cases" in instances where a more holistic approach would be preferred. | [

The term became pejorative following Blaise Pascal's attack on the misuse of the method in his Provincial Letters (1656–57). The French mathematician, religious philosopher and Jansenist sympathiser attacked priests who used casuistic reasoning in confession to pacify wealthy church donors. Pascal charged that \"remorseful\" aristocrats could confess a sin one day, re-commit it the next, then generously donate to the church and return to re-confess their sin, confident that they were being assigned a penance in name only.

5,948 | Chinese input methods for computers | Chinese input methods for computers are methods that allow a computer user to input Chinese characters. Most, if not all, Chinese input methods fall into one of two categories: phonetic readings or root shapes. Methods under the phonetic category usually are easier to learn but are less efficient, thus resulting in slower typing speeds because they typically require users to choose from a list of phonetically similar characters for input, whereas methods under the root shape category allow very precise and speedy input but have a steep learning curve because they often require a thorough understanding of a character's strokes and composition.
Other methods allow users to write characters directly onto touchscreens, such as those found on mobile phones and tablet computers.
Chinese input methods predate the computer. One of the early attempts was an electro-mechanical Chinese typewriter Ming kwai (Chinese: 明快; pinyin: míngkuài; Wade–Giles: ming-k'uai) which was invented by Lin Yutang, a prominent Chinese writer, in the 1940s. It assigned thirty base shapes or strokes to different keys and adopted a new way of categorizing Chinese characters. But the typewriter was not produced commercially and Lin soon found himself deeply in debt.
Before the 1980s, Chinese publishers hired teams of workers and selected a few thousand type pieces from an enormous Chinese character set. Chinese government agencies entered characters using a long, complicated list of Chinese telegraph codes, which assigned different numbers to each character. During the early computer era, Chinese characters were categorized by their radicals or Pinyin romanization, but results were less than satisfactory.
In the 1970s to 1980s, large keyboards with thousands of keys were used to input Chinese. Each key was mapped to several Chinese characters. To type a character, one pressed the character key and then a selection key. There were also experimental "radical keyboards" with dozens to several hundreds keys. Chinese characters were decomposed into "radicals", each of which was represented by a key. Unwieldy and difficult to use, these keyboards became obsolete after the introduction of Cangjie input method, the first method to use only the standard keyboard and make Chinese touch typing possible.
Chu Bong-Foo invented a common input method in 1976 with his Cangjie input method, which assigns different "roots" to each key on a standard computer keyboard. With this method, for example, the character 日 is assigned to the A key, and 月 is assigned to B. Typing them together will result in the character 明 ("bright").
Despite its steeper learning curve, this method remains popular in Chinese communities that use traditional Chinese characters, such as Hong Kong and Taiwan; the method allows very precise input, thus allowing users to type more efficiently and quickly, provided they are familiar with the fairly complicated rules of the method. It was the first method that allowed users to enter more than a hundred Chinese characters per minute. Its popularity is also helped by its omnipresence on traditional Chinese computer systems, since Chu has given up its patent in 1982, stating that it should be part of the cultural asset. Developers of Chinese systems can adopt it freely, and users do not have the hassle of it being absent on devices with Chinese support. Cangjie input programs supporting large CJK character set have been developed.
All methods have their strengths and weaknesses. The pinyin method can be learned rapidly but its maximum input rate is limited. The Wubi takes longer to learn, but expert typists can enter text much more rapidly with it than with phonetic methods. However, Wubi is proprietary, and a version of it has become freely available only after its inventor lost a patent lawsuit in 1997.
Due to these complexities, there is no "standard" method.
In mainland China, the wubi (shape-based) and pinyin methods such as Sogou Pinyin and Google Pinyin are the most popular; in Taiwan, Cangjie, Dayi, Boshiamy, and zhuyin predominate; and in Hong Kong and Macau, the Cangjie is most often taught in schools, while a few schools teach CKC Chinese Input System.
Other methods include handwriting recognition, OCR and voice recognition. The computer itself must first be "trained" before the first or second of these methods are used; that is, the new user enters the system in a special "learning mode" so that the system can learn to identify their handwriting or speech patterns. The latter two methods are used less frequently than keyboard-based input methods and suffer from relatively high error rates, especially when used without proper "training", though higher error rates are an acceptable trade-off to many users. In recent years, online IME have become more scarce, owing to the proliferation of cellphones and apps.
The user enters pronunciations that are converted into relevant Chinese characters. The user must select the desired character from homophones, which are common in Chinese. Modern systems, such as Sogou Pinyin and Google Pinyin, predict the desired characters based on context and user preferences. For example, if one enters the sounds jicheng, the software will type 繼承 (to inherit), but if jichengche is entered, 計程車 (taxi) will appear.
Various Chinese dialects complicate the system. Phonetic methods are mainly based on standard pinyin, Zhuyin/Bopomofo, and Jyutping in China, Taiwan, and Hong Kong, respectively. Input methods based on other varieties of Chinese, like Hakka or Minnan, also exist.
While the phonetic system is easy to learn, choosing appropriate Chinese characters slows typing speed. Most users report a typing speed of fifty characters per minute, though some reach over one hundred per minute. With some phonetic IMEs (Input Method Editors), in addition to predictive input based on previous conversions, it is possible for users to create custom dictionary entries for frequently used characters and phrases, potentially lowering the number of characters required to evoke it.
Shuangpin (雙拼; 双拼), literally dual spell, is a stenographical phonetic input method based on hanyu pinyin that reduces the number of keystrokes for one Chinese character to two by distributing every vowel and consonant composed of more than one letter to a specific key. In most Shuangpin layout schemes such as Xiaohe, Microsoft 2003 and Ziranma, the most frequently used vowels are placed on the middle layer, reducing the risk of repetitive strain injury.
Shuangpin is supported by a large number of pinyin input software including QQ, Microsoft Bing Pinyin, Sogou Pinyin and Google Pinyin. | [

5,950 | Columbus, Ohio | Columbus (/kəˈlʌmbəs/ kə-LUM-bəs) is the capital and most populous city of the U.S. state of Ohio. With a 2020 census population of 905,748, it is the 14th-most populous city in the U.S., the second-most populous city in the Midwest after Chicago, and the third-most populous U.S. state capital after Phoenix, Arizona and Austin, Texas. Columbus is the county seat of Franklin County; it also extends into Delaware and Fairfield counties. It is the core city of the Columbus metropolitan area, which encompasses ten counties in central Ohio. It had a population of 2,138,926 in 2020, making it the largest metropolitan area entirely in Ohio and 32nd-largest metro area in the U.S.
Columbus originated as numerous Native American settlements on the banks of the Scioto River. Franklinton, now a city neighborhood, was the first European settlement, laid out in 1797. The city was founded in 1812 at the confluence of the Scioto and Olentangy rivers, and laid out to become the state capital. The city was named for Italian explorer Christopher Columbus. The city assumed the function of state capital in 1816 and county seat in 1824. Amid steady years of growth and industrialization, the city has experienced numerous floods and recessions. Beginning in the 1950s, Columbus began to experience significant growth; it became the largest city in Ohio in land and population by the early 1990s. Growth has continued in the 21st century, with redevelopment occurring in numerous city neighborhoods, including Downtown.
The city has a diverse economy based on education, government, insurance, banking, defense, aviation, food, clothes, logistics, steel, energy, medical research, health care, hospitality, retail and technology. The metropolitan area is home to the Battelle Memorial Institute, the world's largest private research and development foundation; Chemical Abstracts Service, the world's largest clearinghouse of chemical information; and the Ohio State University, one of the largest universities in the United States. The Greater Columbus area is further home to the headquarters of six Fortune 500 companies, namely Cardinal Health, American Electric Power, L Brands, Nationwide, Bread Financial and Huntington Bancshares.
The city of Columbus was named after 15th-century Italian explorer Christopher Columbus at the city's founding in 1812. It is the largest city in the world named for the explorer, who sailed to and settled parts of the Americas on behalf of Isabella I of Castile and Spain. Although no reliable history exists as to why Columbus, who had no connection to the city or state of Ohio before the city's founding, was chosen as the name for the city, the book Columbus: The Story of a City indicates a state lawmaker and local resident admired the explorer enough to persuade other lawmakers to name the settlement Columbus.
Since the late 20th century, historians have criticized Columbus for initiating the European conquest of America and for abuse, enslavement, and subjugation of natives. Efforts to remove symbols related to the explorer in the city date to the 1990s. Amid the George Floyd protests in 2020, several petitions pushed for the city to be renamed.
A proposed rename for the city which first garnered notability in 2020 is "Flavortown" in honor of celebrity chef Guy Fieri, who was born in Columbus before moving to California; Fieri, though not behind the proposal, expressed flattery and support for the name. The name is additionally noted by local media outlets as honoring the city's significance as a test market for various restaurants and as a reference to the city's culinary culture. The beer company AB InBev, through its social media page for its brand Bud Light, also backed the rename, offering free hard seltzers for the city if the proposal succeeded.
Nicknames for the city have included "the Discovery City", "Arch City", "Cap City", "Cowtown", "The Biggest Small Town in America" and "Cbus."
Between 1000 B.C. and 1700 A.D., the Columbus metropolitan area was a center to indigenous cultures known as the Mound Builders, including the Adena, Hopewell and Fort Ancient peoples. Remaining physical evidence of the cultures are their burial mounds and what they contained. Most of Central Ohio's remaining mounds are located outside of Columbus city boundaries, though the Shrum Mound is maintained, now as part of a public park and historic site. The city's Mound Street derives its name from a mound that existed by the intersection of Mound and High Streets. The mound's clay was used in bricks for most of the city's initial brick buildings; many were subsequently used in the Ohio Statehouse. The city's Ohio History Center maintains a collection of artifacts from these cultures.
The area including present-day Columbus once comprised the Ohio Country, under the nominal control of the French colonial empire through the Viceroyalty of New France from 1663 until 1763.
In the 18th century, European traders flocked to the area, attracted by the fur trade. The area was often caught between warring factions, including American Indian and European interests. In the 1740s, Pennsylvania traders overran the territory until the French forcibly evicted them. Fighting for control of the territory in the French and Indian War (1754-1763) became part of the international Seven Years' War (1756-1763). During this period, the region routinely suffered turmoil, massacres and battles. The 1763 Treaty of Paris ceded the Ohio Country to the British Empire.
Up until the American Revolution, Central Ohio had continuously been the home of numerous indigenous villages. A Mingo village was located at the forks of the Scioto and Olentangy rivers, with Shawnee villages to the south and Wyandot and Delaware villages to the north. Colonial militiamen burned down the Mingo village in 1774 during a raid.
After the American Revolution, the Virginia Military District became part of the Ohio Country as a territory of Virginia. Colonists from the East Coast moved in, but rather than finding an empty frontier, they encountered people of the Miami, Delaware, Wyandot, Shawnee and Mingo nations, as well as European traders. The tribes resisted expansion by the fledgling United States, leading to years of bitter conflict. The decisive Battle of Fallen Timbers resulted in the Treaty of Greenville in 1795, which finally opened the way for new settlements. By 1797, a young surveyor from Virginia named Lucas Sullivant had founded a permanent settlement on the west bank of the forks of the Scioto and Olentangy rivers. An admirer of Benjamin Franklin, Sullivant chose to name his frontier village "Franklinton." The location was desirable for its proximity to the navigable rivers – but Sullivant was initially foiled when, in 1798, a large flood wiped out the new settlement. He persevered, and the village was rebuilt, though somewhat more inland.
After the Revolution, land comprising parts of Franklin and adjacent counties was set aside by the United States Congress for settlement by Canadians and Nova Scotians who were sympathetic to the colonial cause and had their land and possessions seized by the British government. The Refugee Tract, consisting of 103,000 acres (42,000 ha), was 42 miles (68 km) long and 3–4.5 miles (4.8–7.2 km) wide, and was claimed by 67 eligible men. The Ohio Statehouse sits on land once contained in the Refugee Tract.
After Ohio achieved statehood in 1803, political infighting among prominent Ohio leaders led to the state capital moving from Chillicothe to Zanesville and back again. Desiring to settle on a location, the state legislature considered Franklinton, Dublin, Worthington and Delaware before compromising on a plan to build a new city in the state's center, near major transportation routes, primarily rivers. As well, Franklinton landowners had donated two 10-acre (4.0 ha) plots in an effort to convince the state to move its capital there. The two spaces were set to become Capitol Square, including for the Ohio Statehouse and the Ohio Penitentiary. Named in honor of Christopher Columbus, the city was founded on February 14, 1812, on the "High Banks opposite Franklinton at the Forks of the Scioto most known as Wolf's Ridge." At the time, this area was a dense forestland, used only as a hunting ground.
The city was incorporated as a borough on February 10, 1816. Nine people were elected to fill the municipality's various positions of mayor, treasurer and several others.
Between 1816 and 1817, Jarvis W. Pike served as the first appointed mayor. Although the recent War of 1812 had brought prosperity to the area, the subsequent recession and conflicting claims to the land threatened the new town's success. Early conditions were abysmal, with frequent bouts of fevers, attributed to malaria from the flooding rivers, and an outbreak of cholera in 1833. It led Columbus to create the Board of Health, now part of the Columbus Public Health department. The outbreak, which remained in the city from July to September 1833, killed 100 people.
Columbus was without direct river or trail connections to other Ohio cities, leading to slow initial growth. The National Road reached Columbus from Baltimore in 1831, which complemented the city's new link to the Ohio and Erie Canal, both of which facilitated a population boom. A wave of European immigrants led to the creation of two ethnic enclaves on the city's outskirts. A large Irish population settled in the north along Naghten Street (presently Nationwide Boulevard), while the Germans took advantage of the cheap land to the south, creating a community that came to be known as the Das Alte Südende (The Old South End). Columbus's German population constructed numerous breweries, Trinity Lutheran Seminary and Capital University.
With a population of 3,500, Columbus was officially chartered as a city on March 3, 1834. On that day, the legislature carried out a special act, which granted legislative authority to the city council and judicial authority to the mayor. Elections were held in April of that year, with voters choosing John Brooks as the first popularly elected mayor. Columbus annexed the then-separate city of Franklinton in 1837.
In 1850, the Columbus and Xenia Railroad became the first railroad into the city, followed by the Cleveland, Columbus and Cincinnati Railroad in 1851. The two railroads built a joint Union Station on the east side of High Street just north of Naghten (then called North Public Lane). Rail traffic into Columbus increased: by 1875, eight railroads served Columbus, and the rail companies built a new, more elaborate station. Another cholera outbreak hit Columbus in 1849, prompting the opening of the city's Green Lawn Cemetery.
On January 7, 1857, the Ohio Statehouse finally opened after 18 years of construction. Site construction continued until 1861.
Before the abolition of slavery in the Southern United States in 1863, the Underground Railroad was active in Columbus and was led, in part, by James Preston Poindexter. Poindexter arrived in Columbus in the 1830s and became a Baptist preacher and leader in the city's African-American community until the turn of the century.
During the Civil War, Columbus was a major base for the volunteer Union Army. It housed 26,000 troops and held up to 9,000 Confederate prisoners of war at Camp Chase, at what is now the Hilltop neighborhood of west Columbus. Over 2,000 Confederate soldiers remain buried at the site, making it one of the North's largest Confederate cemeteries. North of Columbus, along the Delaware Road, the Regular Army established Camp Thomas, where the 18th U.S. Infantry organized and trained.
By virtue of the Morrill Act of 1862, the Ohio Agricultural and Mechanical College – which eventually became the Ohio State University – was founded in 1870 on the former estate of William and Hannah Neil.
By the end of the 19th century, Columbus was home to several major manufacturing businesses. The city became known as the "Buggy Capital of the World," thanks to the two dozen buggy factories – notably the Columbus Buggy Company, founded in 1875 by C.D. Firestone. The Columbus Consolidated Brewing Company also rose to prominence during this time and might have achieved even greater success were it not for the Anti-Saloon League in neighboring Westerville.
In the steel industry, a forward-thinking man named Samuel P. Bush presided over the Buckeye Steel Castings Company. Columbus was also a popular location for labor organizations. In 1886, Samuel Gompers founded the American Federation of Labor in Druid's Hall on South Fourth Street, and in 1890, the United Mine Workers of America was founded at the old City Hall. In 1894, James Thurber, who would go on to an illustrious literary career in Paris and New York City, was born in the city. Today, Ohio State's theater department has a performance center named in his honor, and his childhood home, the Thurber House, is located in the Discovery District and is on the National Register of Historic Places.
Columbus earned one of its nicknames, "The Arch City," because of the dozens of wooden arches that spanned High Street at the turn of the 20th century. The arches illuminated the thoroughfare and eventually became the means by which electric power was provided to the new streetcars. The city tore down the arches and replaced them with cluster lights in 1914 but reconstructed them from metal in the Short North neighborhood in 2002 for their unique historical interest.
On March 25, 1913, the Great Flood of 1913 devastated the neighborhood of Franklinton, leaving over 90 people dead and thousands of West Side residents homeless. To prevent flooding, the Army Corps of Engineers recommended widening the Scioto River through downtown, constructing new bridges and building a retaining wall along its banks. With the strength of the post-World War I economy, a construction boom occurred in the 1920s, resulting in a new civic center, the Ohio Theatre, the American Insurance Union Citadel and to the north, a massive new Ohio Stadium. Although the American Professional Football Association was founded in Canton in 1920, its head offices moved to Columbus in 1921 to the New Hayden Building and remained in the city until 1941.
In 1922, the association's name was changed to the National Football League. Nearly a decade later, in 1931, at a convention in the city, the Jehovah's Witnesses took that name by which they are known today.
The effects of the Great Depression were less severe in Columbus, as the city's diversified economy helped it fare better than its Rust Belt neighbors. World War II brought many new jobs and another population surge. This time, most new arrivals were migrants from the "extraordinarily depressed rural areas" of Appalachia, who would soon account for more than a third of Columbus's growing population. In 1948, the Town and Country Shopping Center opened in suburban Whitehall, and it is now regarded as one of the first modern shopping centers in the United States.
The construction of the Interstate Highway System signaled the arrival of rapid suburb development in central Ohio. To protect the city's tax base from this suburbanization, Columbus adopted a policy of linking sewer and water hookups to annexation to the city. By the early 1990s, Columbus had grown to become Ohio's largest city in land area and in population.
Efforts to revitalize downtown Columbus have had some success in recent decades, though like most major American cities, some architectural heritage was lost in the process. In the 1970s, landmarks such as Union Station and the Neil House hotel were razed to construct high-rise offices and big retail space. The PNC Bank building was constructed in 1977, as well as the Nationwide Plaza buildings and other towers that sprouted during this period. The construction of the Greater Columbus Convention Center has brought major conventions and trade shows to the city.
The Scioto Mile began development along the riverfront, an area that already had the Miranova Corporate Center and The Condominiums at North Bank Park.
The 2010 United States foreclosure crisis forced the city to purchase numerous foreclosed, vacant properties to renovate or demolish them – at a cost of tens of millions of dollars. In February 2011, Columbus had 6,117 vacant properties, according to city officials.
Since 2010, Columbus has been growing in population and economy; from 2010 to 2017, the city added 164,000 jobs, which ranked second in the United States. In February and March 2020, Columbus reported its first official cases of COVID-19 and declared a state of emergency, with all nonessential businesses closed statewide. There were 69,244 cases of the disease across the city, as of March 11, 2021. Later in 2020, protests over the murder of George Floyd took place in the city from May 28 into August. Columbus and its metro area have experienced growth in the high-tech manufacturing sector, with Intel announcing plans to construct a $20 billion factory and Honda expanding its presence along with LG Energy Solutions with a $4.4 billion battery manufactory facility in Fayette County.
The COVID-19 pandemic muted activity in Columbus, especially in its downtown core, from 2020 to 2022. By late 2022, foot traffic in Downtown Columbus began to exceed pre-pandemic rates; one of the quickest downtown areas to recover in the United States.
The confluence of the Scioto and Olentangy rivers is just northwest of Downtown Columbus. Several smaller tributaries course through the Columbus metropolitan area, including Alum Creek, Big Walnut Creek and Darby Creek. Columbus is considered to have relatively flat topography thanks to a large glacier that covered most of Ohio during the Wisconsin Ice Age. However, there are sizable differences in elevation through the area, with the high point of Franklin County being 1,132 ft (345 m) above sea level near New Albany, and the low point being 670 ft (200 m) where the Scioto River leaves the county near Lockbourne.
Several ravines near the rivers and creeks also add variety to the landscape. Tributaries to Alum Creek and the Olentangy River cut through shale, while tributaries to the Scioto River cut through limestone. The numerous rivers and streams beside low-lying areas in Central Ohio contribute to a history of flooding in the region; the most significant was the Great Flood of 1913 in Columbus, Ohio.
The city has a total area of 223.11 square miles (577.85 km), of which 217.17 square miles (562.47 km) is land and 5.94 square miles (15.38 km) is water. Columbus currently has the largest land area of any Ohio city; this is due to Jim Rhodes's tactic to annex suburbs while serving as mayor. As surrounding communities grew or were constructed, they came to require access to waterlines, which was under the sole control of the municipal water system. Rhodes told these communities that if they wanted water, they would have to submit to assimilation into Columbus.
Columbus has a wide diversity of neighborhoods with different characters, and is thus sometimes known as a "city of neighborhoods." Some of the most prominent neighborhoods include the Arena District, the Brewery District, Clintonville, Franklinton, German Village, The Short North and Victorian Village.
The city's climate is humid continental (Köppen climate classification Dfa) transitional with the humid subtropical climate to the south characterized by warm, muggy summers and cold, dry winters. Columbus is within USDA hardiness zone 6b, bordering on 7a. Winter snowfall is relatively light, since the city is not in the typical path of strong winter lows, such as the Nor'easters that strike cities farther east. It is also too far south and west for lake-effect snow from Lake Erie to have much effect, although the lakes to the north contribute to long stretches of cloudy spells in winter.
The highest temperature recorded in Columbus is 106 °F (41 °C), which occurred twice during the Dust Bowl of the 1930s: once on July 21, 1934, and again on July 14, 1936. The lowest recorded temperature was −22 °F (−30 °C), occurring on January 19, 1994.
Columbus is subject to severe weather typical to the Midwestern United States. Severe thunderstorms can bring lightning, large hail and on rare occasions tornadoes, especially during the spring and sometimes through fall. A tornado that occurred on October 11, 2006, caused F2 damage. Floods, blizzards and ice storms can also occur from time to time.
In the 2020 United States census, there were 905,748 people and 362,626 households residing in the city.
The racial makeup of the city was 57.4% White, 29.2% Black or African American, 0.2% Native American or Alaska Native, and 5.9% Asian. Hispanic or Latino of any race made up 6.3% of the population.
In the 2010 United States census, there were 787,033 people, 331,602 households and 176,037 families residing in the city. The population density was 3,624 inhabitants per square mile (1,399.2/km). There were 370,965 housing units at an average density of 1,708.2 per square mile (659.5/km).
The racial makeup of the city included 815,985 races tallied, as some residents recognized multiple races. The racial makeup was 61.9% White, 29.1% Black or African American, 1% Native American or Alaska Native, 4.6% Asian, 0.2% Native Hawaiian or Pacific Islander, and 3.2% from other races. Hispanic or Latino of any race were 5.9% of the population.
Columbus historically had a significant population of white people. In 1900, whites made up 93.4% of the population. Although European immigration has declined, the Columbus metropolitan area has recently experienced increases in African, Asian and Latin American immigration, including groups from Mexico, India, Nepal, Bhutan, Somalia and China. While the Asian population is diverse, the city's Hispanic community is mainly made up of Mexican Americans, although there is a notable Puerto Rican population. Many other countries of origin are represented in lesser numbers, largely due to the international draw of Ohio State University. 2008 estimates indicate that roughly 116,000 of the city's residents are foreign-born, accounting for 82% of the new residents between 2000 and 2006 at a rate of 105 per week. 40% of the immigrants came from Asia, 23% from Africa, 22% from Latin America and 13% from Europe. The city had the second-largest Somali and Somali American population in the country, as of 2004, as well as the largest expatriate Bhutanese-Nepali population in the world, as of 2018.
Due to its demographics, which include a mix of races and a wide range of incomes, as well as urban, suburban and nearby rural areas, Columbus is considered a "typical" American city, leading retail and restaurant chains to use it as a test market for new products. For similar reasons, the city was chosen as the launch city for the QUBE cable television service.
Columbus has maintained a steady population growth since its establishment. Its slowest growth, from 1850 to 1860, is primarily attributed to the city's cholera epidemic in the 1850s.
According to the 2017 Japanese Direct Investment Survey by the Consulate-General of Japan, Detroit, 838 Japanese nationals lived in Columbus, making it the municipality with the state's second-largest Japanese national population, after Dublin.
Columbus is home to a proportional LGBT community, with an estimated 34,952 gay, lesbian or bisexual residents. The 2018 American Community Survey (ACS) reported an estimated 366,034 households, 32,276 of which were held by unmarried partners. 1,395 of these were female householder and female-partner households, and 1,456 were male householder and male-partner households. Columbus has been rated as one of the best cities in the country for gays and lesbians to live, and also as the most underrated gay city in the country. In July 2012, three years prior to legal same-sex marriage in the United States, the Columbus City Council unanimously passed a domestic partnership registry.
Columbus has numerous Italian Americans, with groups including the Columbus Italian Club, Columbus Piave Club and the Abruzzi Club. Italian Village, a neighborhood near Downtown Columbus, has had a prominent Italian American community since the 1890s.
The community has helped promote the influence Christopher Columbus had in drawing European attention to the Americas. The Italian explorer, erroneously credited with the lands' discovery, has been posthumously criticized by historians for initiating colonization and for abuse, enslavement and subjugation of natives. In addition to the city being named for the explorer, its seal and flag depict a ship he used for his first voyage to the Americas, the Santa María. A similar-size replica of the ship, the Santa Maria Ship & Museum, was displayed downtown from 1991 to 2014. The city's Discovery District and Discovery Bridge are named in reference to Columbus's "discovery" of the Americas; the bridge includes artistic bronze medallions featuring symbols of the explorer. Genoa Park, downtown, is named after Genoa, the birthplace of Christopher Columbus and one of Columbus's sister cities.
The Christopher Columbus Quincentennial Jubilee, celebrating the 500th anniversary of Columbus's first voyage, was held in the city in 1992. Its organizers spent $95 million on it, creating the horticultural exhibition AmeriFlora '92. The organizers also planned to create a replica Native American village, among other attractions. Local and national native leaders protested the event with a day of mourning, followed by protests and fasts at City Hall. The protests prevented the native village from being exhibited, and annual fasts continued until 1997. A protest also took place during the dedication of the Santa Maria replica, an event held in late 1991 on the day before Columbus Day and in time for the jubilee.
The city has three outdoor statues of the explorer; the statue at City Hall was acquired, delivered and dedicated with the assistance of the Italian American community. Protests in 2017 aimed for this statue to be removed, followed by the city in 2018 ceasing to recognize Columbus Day as a city holiday. During the 2020 George Floyd protests, petitions were created to remove all three statues and rename the city of Columbus. Two of the statues – one at City Hall and the other at Columbus State Community College – were removed, while the city is also looking into changing its flag and seal to remove the reference to Christopher Columbus. The future of the third statue, at the Ohio Statehouse, will be discussed in a meeting on July 16.
The city was the first of eight cities to be offered the 360 ft (110 m) Birth of the New World statue, in 1993. The statue, also of Christopher Columbus, was completed in Puerto Rico in 2016, and is the tallest in the United States – 45 ft (14 m) taller than the Statue of Liberty, including its pedestal. At least six U.S. cities rejected it, including Columbus, based on its height and design.
According to the 2019 American Values Atlas, 26% of Columbus metropolitan area residents are unaffiliated with a religious tradition. 17% of area residents identify as White evangelical Protestants, 14% as White mainline Protestants, 11% as Black Protestants, 11% as White Catholics, 5% as Hispanic Catholics, 3% as other nonwhite Catholics, 2% as other nonwhite Protestants and 2% as Mormons. Hindus, Buddhists, Jews and Latino Protestants each made up 1% of the population, while Jehovah's Witnesses, Orthodox Christians, Muslims, Unitarians, and members of New Age or other religions each made up under 0.5% of the population.
Places of worship include Baptist, Evangelical, Greek Orthodox, Latter-day Saints, Lutheran, Presbyterian, Quaker, Roman Catholic, and Unitarian Universalist churches. Columbus also hosts several Islamic mosques, Jewish synagogues, Buddhist centers, Hindu temples and a branch of the International Society for Krishna Consciousness. Religious teaching institutions include the Pontifical College Josephinum and several private schools led by Christian organizations.
Columbus has a generally strong and diverse economy based on education, insurance, banking, fashion, defense, aviation, food, logistics, steel, energy, medical research, health care, hospitality, retail and technology. In 2010, it was one of the 10 best big cities in the country, according to Relocate America, a real estate research firm.
According to the Federal Reserve Bank of St Louis, the GDP of Columbus in 2019 was $134 billion (~$152 billion in 2022).
During the Great Recession between 2007 and 2009, Columbus's economy was not impacted as much as the rest of the country, due to decades of diversification work by long-time corporate residents, business leaders and political leaders. The administration of former mayor Michael B. Coleman continued this work, although the city faced financial turmoil and had to increase taxes, allegedly due in part to fiscal mismanagement. Because Columbus is the state capital, there is a large government presence in the city. Including city, county, state and federal employers, government jobs provide the largest single source of employment within Columbus.
In 2019, the city had six corporations named to the U.S. Fortune 500 list: Alliance Data, Nationwide Mutual Insurance Company, American Electric Power, L Brands, Huntington Bancshares and Cardinal Health in suburban Dublin. Other major employers include schools (e.g., the Ohio State University) and hospitals (among others, Wexner Medical Center and Nationwide Children's Hospital, which are among the teaching hospitals of the Ohio State University College of Medicine), high-tech research and development such as the Battelle Memorial Institute, information/library companies such as OCLC and Chemical Abstracts Service, steel processing and pressure cylinder manufacturer Worthington Industries, financial institutions such as JPMorgan Chase and Huntington Bancshares, as well as Owens Corning. Fast-food chains Wendy's and White Castle are also headquartered in the Columbus area. Major foreign corporations operating or with divisions in the city include Germany-based Siemens and Roxane Laboratories, Finland-based Vaisala, Tomasco Mulciber Inc., A Y Manufacturing, as well as Switzerland-based ABB and Mettler Toledo. The city also has a significant fashion and retail presence, home to companies such as Big Lots, L Brands, Abercrombie & Fitch, DSW and Express.
North Market, a public market and food hall, is located downtown near the Short North. It is the only remaining public market of Columbus's original four marketplaces.
Numerous restaurant chains are based in the Columbus area, including Charleys Philly Steaks, Bibibop Asian Grill, Steak Escape, White Castle, Cameron Mitchell Restaurants, Bob Evans Restaurants, Max & Erma's, Damon's Grill, Donatos Pizza and Wendy's. Wendy's, the world's third-largest hamburger fast-food chain, operated its first store downtown as both a museum and a restaurant until March 2007, when the establishment was closed due to low revenue. The company is presently headquartered outside the city in nearby Dublin. Budweiser has a major brewery located on the north side, just south of I-270 and Worthington. Columbus is also home to many local micro breweries and pubs. Asian frozen food manufacturer Kahiki Foods was located on the east side of Columbus, created during the operation of the Kahiki Supper Club restaurant in Columbus. The food company now operates in the suburb of Gahanna and has been owned by the South Korean-based company CJ CheilJedang since 2018. Wasserstrom Company, a major supplier of equipment and supplies for restaurants, is located on the north side.
Columbus has over 170 notable buildings listed on the National Register of Historic Places; it also maintains its own register, the Columbus Register of Historic Properties, with 82 entries. The city also maintains four historic districts not listed on its register: German Village, Italian Village, Victorian Village, and the Brewery District.
Construction of the Ohio Statehouse began in 1839 on a 10-acre (4 ha) plot of land donated by four prominent Columbus landowners. This plot formed Capitol Square, which was not part of the city's original layout. Built of Columbus limestone from the Marble Cliff Quarry Co., the Statehouse stands on foundations 18 feet (5.5 m) deep that were laid by prison labor gangs rumored to have been composed largely of masons jailed for minor infractions. It features a central recessed porch with a colonnade of a forthright and primitive Greek Doric mode. A broad and low central pediment supports the windowed astylar drum under an invisibly low saucer dome that lights the interior rotunda. There are several artworks within and outside the building, including the William McKinley Monument dedicated in 1907. Unlike many U.S. state capitol buildings, the Ohio State Capitol owes little to the architecture of the national Capitol. During the Statehouse's 22-year construction, seven architects were employed. The Statehouse was opened to the legislature and the public in 1857 and completed in 1861, and is located at the intersection of Broad and High streets in downtown Columbus.
Within the Driving Park heritage district lies the original home of Eddie Rickenbacker, a World War I fighter pilot ace. Built in 1895, the house was designated a National Historic Landmark in 1976.
Demolition has been a common trend in Columbus for a long period of time, and continues into the present day. Preservationists and the public have sometimes run into conflict with developers hoping to revitalize an area, and historically with the city and state government, which led programs of urban renewal in the 20th century.
Columbus has a wide variety of museums and galleries. Its primary art museum is the Columbus Museum of Art, which operates its main location as well as the Pizzuti Collection, featuring contemporary art. The museum, founded in 1878, focuses on European and American art up to early modernism that includes extraordinary examples of Impressionism, German Expressionism and Cubism. Another prominent art museum in the city is the Wexner Center for the Arts, a contemporary art gallery and research facility operated by the Ohio State University.
The Ohio History Connection is headquartered in Columbus, with its flagship museum, the 250,000-square-foot (23,000 m) Ohio History Center, 4 mi (6.4 km) north of downtown. Adjacent to the museum is Ohio Village, a replica of a village around the time of the American Civil War. The Columbus Historical Society also features historical exhibits, which focus more closely on life in Columbus.
COSI is a large science and children's museum in downtown Columbus. The present building, the former Central High School, was completed in November 1999, opposite downtown on the west bank of the Scioto River. In 2009, Parents magazine named COSI one of the 10 best science centers for families in the country. Other science museums include the Orton Geological Museum and the Museum of Biological Diversity, which are both part of the Ohio State University.
The Franklin Park Conservatory is the city's botanical garden, which opened in 1895. It features over 400 species of plants in a large Victorian-style glass greenhouse building that includes rain forest, desert and Himalayan mountain biomes. The conservatory is located just east of Downtown in Franklin Park
Biographical museums include the Thurber House (documenting the life of cartoonist James Thurber), the Jack Nicklaus Museum (documenting the golfer's career, located on the OSU campus) and the Kelton House Museum and Garden, the latter of which being a historic house museum memorializing three generations of the Kelton family, the house's use as a documented station on the Underground Railroad, and overall Victorian life.
The National Veterans Memorial and Museum, which opened in 2018, focuses on the personal stories of military veterans throughout U.S. history. The museum replaced the Franklin County Veterans Memorial, which opened in 1955.
Other notable museums in the city include the Central Ohio Fire Museum, Billy Ireland Cartoon Library & Museum and the Ohio Craft Museum.
Columbus is the home of many performing arts institutions including the Columbus Symphony Orchestra, Opera Columbus, BalletMet Columbus, the ProMusica Chamber Orchestra, CATCO, Columbus Children's Theatre, Shadowbox Live, and the Columbus Jazz Orchestra. Throughout the summer, the Actors' Theatre of Columbus offers free performances of Shakespearean plays in an open-air amphitheater in Schiller Park in historic German Village.
The Columbus Youth Ballet Academy was founded in the 1980s by ballerina and artistic director Shir Lee Wu, a discovery of Martha Graham. Wu is now the artistic director of the Columbus City Ballet School.
Columbus has several large concert venues, including the Nationwide Arena, Value City Arena, Express Live!, Mershon Auditorium and the Newport Music Hall.
In May 2009, the Lincoln Theatre, formerly a center for Black culture in Columbus, reopened after an extensive restoration. Not far from the Lincoln Theatre is the King Arts Complex, which hosts a variety of cultural events. The city also has several theaters downtown, including the historic Palace Theatre, the Ohio Theatre and the Southern Theatre. Broadway Across America often presents touring Broadway musicals in these larger venues. The Vern Riffe Center for Government and the Arts houses the Capitol Theatre and three smaller studio theaters, providing a home for resident performing arts companies.
Movies filmed in the Columbus metropolitan area include Teachers in 1984, Tango & Cash in 1989, Little Man Tate in 1991, Air Force One in 1997, Traffic in 2000, Speak in 2004, Bubble in 2005, Liberal Arts in 2012, Parker in 2013, and I Am Wrath in 2016, Aftermath in 2017, They/Them/Us in 2021, and Bones and All in 2022. The 2018 film Ready Player One is set in Columbus, though not filmed in the city.
Columbus hosts two major league professional sports teams: the Columbus Blue Jackets of the National Hockey League (NHL), which play at Nationwide Arena, and the Columbus Crew of Major League Soccer (MLS), which play at Lower.com Field. The Crew previously played at Historic Crew Stadium, the first soccer-specific stadium built in the United States for a Major League Soccer team. The Crew were one of the original members of MLS and won their first MLS Cup in 2008, with a second title in 2020. The Columbus Crew moved into Lower.com Field in the summer of 2021, which will also feature a mixed-use development site named Confluence Village.
The Columbus Clippers, the International League affiliate of the Cleveland Guardians, play in Huntington Park, which opened in 2009.
The city was home to the Panhandles/Tigers football team from 1901 to 1926; they are credited with playing in the first NFL game against another NFL opponent. In the late 1990s, the Columbus Quest won the only two championships during American Basketball League's two-and-a-half season existence.
The Ohio Aviators were based in Obetz, Ohio, and began play in the only PRO Rugby season before the league folded.
Columbus will also have one of the first teams in the Pro Volleyball Federation which is expected to launch in February 2024. The Columbus Fury will play at Nationwide Arena for their home games.
Columbus is home to one of the nation's most competitive intercollegiate programs, the Ohio State Buckeyes of Ohio State University. The program has placed in the top 10 final standings of the Director's Cup five times since 2000–2001, including No. 3 for the 2002–2003 season and No. 4 for the 2003–2004 season. The university funds 36 varsity teams, consisting of 17 male, 16 female and three co-educational teams. In 2007–2008 and 2008–2009, the program generated the second-most revenue for college programs behind the Texas Longhorns of The University of Texas at Austin.
The Ohio State Buckeyes are a member of the NCAA's Big Ten Conference, and their football team plays home games at Ohio Stadium. The Ohio State–Michigan football game (known colloquially as "The Game") is the final game of the regular season and is played in November each year, alternating between Columbus and Ann Arbor, Michigan. In 2000, ESPN ranked the Ohio State–Michigan game as the greatest rivalry in North American sports. Moreover, "Buckeye fever" permeates Columbus culture year-round and forms a major part of Columbus's cultural identity. Former New York Yankees owner George Steinbrenner, an Ohio native who received a master's degree from Ohio State and coached in Columbus, was an Ohio State football fan and major donor to the university who contributed to the construction of the band facility at the renovated Ohio Stadium, which bears his family's name. During the winter months, the Buckeyes basketball and hockey teams are also major sporting attractions.
Columbus has a long history in motorsports, hosting the world's first 24-hour car race at the Columbus Driving Park in 1905, which was organized by the Columbus Auto Club. The Columbus Motor Speedway was built in 1945 and held its first motorcycle race in 1946. In 2010, the Ohio State University student-built Buckeye Bullet 2, a fuel-cell vehicle, set an FIA world speed record for electric vehicles in reaching 303.025 mph, eclipsing the previous record of 302.877 mph.

The Columbus Bullies were two-time champions of the American Football League (1940–1941). The Columbus Thunderbolts were formed in 1991 for the Arena Football League, and then relocated to Cleveland as the Cleveland Thunderbolts; the Columbus Destroyers were the next team of the AFL, playing from 2004 until the league's demise in 2008 and returned for single season in 2019 until the league folded a second time.
Ohio Roller Derby (formerly Ohio Roller Girls) was founded in Columbus in 2005 and still competes internationally in Women's Flat Track Derby Association play. The team is regularly ranked in the top 60 internationally.
Columbus's Recreation and Parks Department oversees about 370 city parks. Also in the area are 19 regional parks and the Metro Parks, which are part of the Columbus and Franklin County Metropolitan Park District.
These parks include Clintonville's Whetstone Park and the Columbus Park of Roses, a 13-acre (5.3 ha) rose garden. The Chadwick Arboretum on Ohio State's campus features a large and varied collection of plants, while its Olentangy River Wetland Research Park is an experimental wetland open to the public. Downtown, the painting A Sunday Afternoon on the Island of La Grande Jatte is represented in topiary at Columbus's Topiary Park. Also near downtown, the Scioto Audubon Metro Park on the Whittier Peninsula opened in 2009 and includes a large Audubon nature center focused on the birdwatching the area is known for.
The Columbus Zoo and Aquarium's collections include lowland gorillas, polar bears, manatees, Siberian tigers, cheetahs and kangaroos. Also in the zoo complex is the Zoombezi Bay water park and amusement park.

In mid-May from 2007 to 2018, Columbus was home to Rock on the Range, which was held at Historic Crew Stadium and marketed as America's biggest rock festival. The festival, which took place on a Friday, Saturday and Sunday, has hosted Metallica, Red Hot Chili Peppers, Slipknot and other notable bands. In May 2019, it was officially replaced by the Sonic Temple Art & Music Festival.
During the first weekend in June, the bars of Columbus's North Market District host the Park Street Festival, which attracts thousands of visitors to a massive party in bars and on the street. June's second-to-last weekend sees one of the Midwest's largest gay pride parades, Columbus Pride, reflecting the city's sizable gay population. During the last weekend of June, Goodale Park hosts ComFest (short for "Community Festival"), an immense three-day music festival marketed as the largest non-commercial festival in the U.S., with art vendors, live music on multiple stages, hundreds of local social and political organizations, body painting and beer.
Greek Festival is held in August or September at the Greek Orthodox Church downtown.
The Hot Times Community Arts & Music Festival, a celebration of music, arts, food and diversity, is held annually in the Olde Towne East neighborhood.
The city's largest dining event, Restaurant Week Columbus, is held twice a year in mid-January and mid-July. In 2010, more than 40,000 diners went to 40 participating restaurants, and $5,000 (~$6,710 in 2022) was donated the Mid-Ohio Foodbank on behalf of sponsors and participating restaurants.
The Juneteenth Ohio Festival is held each year at Franklin Park on Father's Day weekend. Started by Mustafaa Shabazz, Juneteenth Ohio is one of the largest African American festivals in the United States, including three full days of music, food, dance and entertainment by local and national recording artists. The festival holds a Father's Day celebration, honoring local fathers.
Around the Fourth of July, Columbus hosts Red, White & Boom! on the Scioto riverfront downtown, attracting crowds of over 500,000 people and featuring the largest fireworks display in Ohio. The Doo Dah Parade is also held at this time.
During Memorial Day Weekend, the Asian Festival is held in Franklin Park. Hundreds of restaurants, vendors and companies open up booths, and traditional music is played, martial arts are performed and cultural exhibits are set up.
The Jazz & Rib Fest is a free downtown event held each July, featuring jazz artists like Randy Weston, D. Bohannon Clark and Wayne Shorter, along with rib vendors from around the country.
The Short North is host to the monthly Gallery Hop, which attracts hundreds to the neighborhood's art galleries (which all open their doors to the public until late at night) and street musicians. The Hilltop Bean Dinner is an annual event held on Columbus's West Side that celebrates the city's Civil War heritage near the historic Camp Chase Cemetery. At the end of September, German Village throws an annual Oktoberfest celebration that features German food, beer, music and crafts.
The Short North also hosts HighBall Halloween and Masquerade on High, a fashion show and street parade that closes down High Street. In 2011, in its fourth year, HighBall Halloween gained notoriety as it accepted its first Expy award. HighBall Halloween has much to offer for those interested in fashion and the performing and visual arts, or for those who want to celebrate Halloween with food and drinks from all around the city. Each year, the event is put on with a different theme.
Columbus also hosts many conventions in the Greater Columbus Convention Center, a large convention center on the north edge of downtown. Completed in 1993, the 1.8-million-square-foot (170,000 m) convention center was designed by architect Peter Eisenman, who also designed the Wexner Center.
Both of the metropolitan area's major shopping centers are located in Columbus: Easton Town Center and Polaris Fashion Place.
Developer Richard E. Jacobs built the area's first three major shopping malls in the 1960s: Westland, Northland and Eastland. Near Northland Mall was The Continent, an open-air mall in the Northland area, mostly vacant and pending redevelopment. Columbus City Center was built downtown in 1988, alongside the first location of Lazarus; this mall closed in 2009 and was demolished in 2011. Easton Town Center was built in 1999 and Polaris Fashion Place in 2001.
The City of Columbus has focused on reducing its environmental impact and carbon footprint. In 2020, a citywide ballot measure was approved, giving Columbus an electricity aggregation plan which will supply it with 100% renewable energy by the start of 2023. Its vendor, AEP Energy, plans to construct new wind and solar farms in Ohio to help supply the electricity.
The largest sources of pollution in the county, as of 2019, are the Ohio State University's McCracken Power Plant, the landfill operated by the Solid Waste Authority of Central Ohio (SWACO) and the Anheuser-Busch Columbus Brewery. Anheuser-Busch has a company-wide goal of reducing emissions by 25% by 2025. Ohio State plans to construct a new heat and power plant, also powered by fossil fuels, but set to reduce emissions by about 30%. SWACO manages to capture 75% of its methane emissions to use in producing energy, and is looking to reduce emissions further.
The city is administered by a mayor and a seven-member unicameral council elected in two classes every two years to four-year terms at large. Columbus is the largest city in the United States that elects its city council at large as opposed to districts. The mayor appoints the director of safety and the director of public service. The people elect the auditor, municipal court clerk, municipal court judges and city attorney. A charter commission, elected in 1913, submitted a new charter in May 1914, offering a modified federal form, with a number of progressive features, such as nonpartisan ballot, preferential voting, recall of elected officials, the referendum and a small council elected at large. The charter was adopted, effective January 1, 1916. Andrew Ginther has been the mayor of Columbus since 2016.
As Ohio's capital and the county seat, Columbus hosts numerous federal, state, county and city government offices and courts.
Federal offices include the Joseph P. Kinneary U.S. Courthouse, one of several courts for the District Court for the Southern District of Ohio, after moving from 121 E. State St. in 1934. Another federal office, the John W. Bricker Federal Building, has offices for U.S. Senator Sherrod Brown, as well as for the Internal Revenue Service, the Social Security Administration and the Departments of Housing & Urban Development and Agriculture.
The State of Ohio's capitol building, the Ohio Statehouse, is located in the center of downtown on Capitol Square. It houses the Ohio House of Representatives and Ohio Senate. It also contains the ceremonial offices of the governor, lieutenant governor, state treasurer and state auditor. The Supreme Court, Court of Claims and Judicial Conference are located in the Thomas J. Moyer Ohio Judicial Center downtown by the Scioto River. The building, built in 1933 to house 10 state agencies along with the State Library of Ohio, became the Supreme Court after extensive renovations from 2001 to 2004.
Franklin County operates the Franklin County Government Center, a complex at the southern end of downtown Columbus. The center includes the county's municipal court, common pleas court, correctional center, juvenile detention center and sheriff's office.
Near City Hall, the Michael B. Coleman Government Center holds offices for the departments of building and zoning services, public service, development and public utilities. Also nearby is 77 North Front Street, which holds Columbus's city attorney office, income-tax division, public safety, human resources, civil service and purchasing departments. The structure, built in 1929, was the police headquarters until 1991, and was then dormant until it was given a $34 million renovation from 2011 to 2013.
Municipal police duties are performed by the Columbus Division of Police, while emergency medical services (EMS) and fire protection are through the Columbus Division of Fire.
Ohio Homeland Security operates the Strategic Analysis and Information Center (SAIC) fusion center in Columbus's Hilltop neighborhood. The facility is the state's primary public intelligence hub and one of the few in the country that uses state, local, federal and private resources.
Columbus has a history of governmental and nonprofit support for low-income residents and the homeless. Nevertheless, the homelessness rate has steadily risen since at least 2007. Poverty and differences in quality of life have grown, as well; Columbus was noted as the second-most economically segregated large metropolitan area in 2015, in a study by the University of Toronto. It also ranked 45th of the 50 largest metropolitan areas in terms of social mobility, according to a 2015 Harvard University study.
Columbus is the home of two public colleges: the Ohio State University, one of the largest college campuses in the United States, and Columbus State Community College. In 2009, Ohio State University was ranked No. 19 in the country by U.S. News & World Report on its list of best public universities, and No. 56 overall, scoring in the first tier of schools nationally. Some of Ohio State's graduate school programs placed in the top 5, including No. 5 for both best veterinary programs and best pharmacy programs. The specialty graduate programs of social psychology was ranked No. 2, dispute resolution was No. 5, vocational education was No. 2, and elementary education, secondary teacher education, administration/supervision was No. 5.
Private institutions in Columbus include Capital University Law School, the Columbus College of Art and Design, Fortis College, DeVry University, Ohio Business College, Miami-Jacobs Career College, Ohio Institute of Health Careers, Bradford School and Franklin University, as well as the religious schools Bexley Hall Episcopal Seminary, Mount Carmel College of Nursing, Ohio Dominican University, Pontifical College Josephinum and Trinity Lutheran Seminary. Three major suburban schools also have an influence on Columbus's educational landscape: Bexley's Capital University, Westerville's Otterbein University and Delaware's Ohio Wesleyan University.
Columbus City Schools (CCS) is the largest district in Ohio, with 55,000 pupils. CCS operates 142 elementary, middle and high schools, including a number of magnet schools (which are referred to as alternative schools within the school system).
The suburbs operate their own districts, typically serving students in one or more townships, with districts sometimes crossing municipal boundaries. The Roman Catholic Diocese of Columbus also operates several parochial elementary and high schools. The area's second-largest school district is South-Western City Schools, which encompasses southwestern Franklin County, including a slice of Columbus itself. Other portions of Columbus are zoned to the Dublin, Hilliard, New Albany-Plain, Westerville and Worthington school districts.
There are also several private schools in the area, such as St. Paul's Lutheran School, a K-8 Christian school of the Wisconsin Evangelical Lutheran Synod in Columbus.
Some sources determine that the first kindergarten in the United States was established here by Louisa Frankenberg, a former student of Friedrich Fröbel. Frankenberg immigrated to the city in 1838 and opened her kindergarten in the German Village neighborhood in that year. The school did not work out, so she returned to Germany in 1840. In 1858, Frankenberg returned to Columbus and established another early kindergarten in the city. Frankenberg is often overlooked, with Margarethe Schurz instead given credit for her "First Kindergarten" she operated for two years.
In addition, Indianola Junior High School (now the Graham Elementary and Middle School) became the nation's first junior high school in 1909, helping to bridge the difficult transition from elementary to high school at a time when only 48% of students continued their education after the ninth grade.
The Columbus Metropolitan Library (CML) has served central Ohio residents since 1873. The system has 23 locations throughout Central Ohio, with a total collection of 3 million items. This library is one of the country's most-used library systems and is consistently among the top-ranked large city libraries according to Hennen's American Public Library Ratings. CML was rated the No. 1 library system in the nation in 1999, 2005 and 2008. It has been in the top four every year since 1999, when the rankings were first published in the American Libraries magazine, often challenging upstate neighbor Cuyahoga County Public Library for the top spot.
The classes of the Columbus Japanese Language School, a weekend Japanese school, are held in a facility from the school district in Marysville, while the school office is in Worthington. Previously it held classes at facilities in the city of Columbus.
Several weekly and daily newspapers serve Columbus and Central Ohio. The major daily newspaper in Columbus is The Columbus Dispatch. There are also neighborhood- or suburb-specific papers, such as the Dispatch Printing Company's ThisWeek Community News, the Columbus Messenger, the Clintonville Spotlight and the Short North Gazette. The Lantern and 1870 serve the Ohio State University community. Alternative arts, culture or politics-oriented papers include ALIVE (formerly the independent Columbus Alive and now owned by the Columbus Dispatch), Columbus Free Press and Columbus Underground (digital-only). The Columbus Magazine, CityScene, 614 Magazine and Columbus Monthly are the city's magazines.
Columbus is the base for 12 television stations and is the 32nd-largest television market as of September 24, 2016. Columbus is also home to the 36th-largest radio market.
Numerous medical systems operate in Columbus and Central Ohio. These include OhioHealth, which has three hospitals in the city proper: Grant Medical Center, Riverside Methodist Hospital, and Doctors Hospital; Mount Carmel Health System, which has one hospital among other facilities; the Ohio State University Wexner Medical Center, which has a primary hospital complex and an east campus in Columbus; and Nationwide Children's Hospital, which is an independently operated hospital for pediatric health care. Hospitals in Central Ohio are ranked favorably by the U.S. News & World Report, where numerous hospitals are ranked as among the best in particular fields in the United States. Nationwide Children's is regarded as among the top 10 children's hospitals in the country, according to the report.
Numerous utility companies operate in Central Ohio. Within Columbus, power is sourced from Columbus Southern Power, an American Electric Power subsidiary. Natural gas is provided by Columbia Gas of Ohio, while water is sourced from the City of Columbus Division of Water.
The city's two main corridors since its founding are Broad and High Streets. They both traverse beyond the extent of the city; High Street is the longest in Columbus, running 13.5 mi (21.7 km) (23.4 across the county), while Broad Street is longer across the county, at 25.1 mi (40.4 km).
The city's street plan originates downtown and extends into the old-growth neighborhoods, following a grid pattern with the intersection of High Street (running north–south) and Broad Street (running east–west) at its center. North–south streets run 12 degrees west of due north, parallel to High Street; the avenues (vis. Fifth Avenue, Sixth Avenue, Seventh Avenue, and so on) run 12 degrees off from east–west.
The address system begins its numbering at the intersection of Broad and High, with numbers increasing in magnitude with distance from Broad or High, as well as cardinal directions used alongside street names. Numbered avenues begin with First Avenue, about 1+1⁄4 mi (2.0 km) north of Broad Street, and increase in number as one progresses northward. Numbered streets begin with Second Street, which is two blocks west of High Street, and Third Street, which is a block east of High Street, then progress eastward from there. Even-numbered addresses are on the north and east sides of streets, putting odd addresses on the south and west sides of streets. A difference of 700 house numbers means a distance of about 1 mi (1.6 km) (along the same street).
Other major, local roads in Columbus include Main Street, Morse Road, Dublin-Granville Road (SR-161), Cleveland Avenue/Westerville Road (SR-3), Olentangy River Road, Riverside Drive, Sunbury Road, Fifth Avenue and Livingston Avenue.
Columbus is bisected by two major Interstate Highways: Interstate 70 running east–west and Interstate 71 running north to roughly southwest. They combine downtown for about 1.5 mi (2.4 km) in an area locally known as "The Split", which is a major traffic congestion point, especially during rush hour. U.S. Route 40, originally known as the National Road, runs east–west through Columbus, comprising Main Street to the east of downtown and Broad Street to the west. U.S. Route 23 runs roughly north–south, while U.S. Route 33 runs northwest-to-southeast. The Interstate 270 Outerbelt encircles most of the city, while the newly redesigned Innerbelt consists of the Interstate 670 spur on the north side (which continues to the east past the Airport and to the west where it merges with I-70), State Route 315 on the west side, the I-70/71 split on the south side and I-71 on the east. Due to its central location within Ohio and abundance of outbound roadways, nearly all of the state's destinations are within a two- or three-hour drive of Columbus.
The Columbus riverfront hosts several bridges. The Discovery Bridge connects downtown to Franklinton across Broad Street. The bridge opened in 1992, replacing a 1921 concrete arch bridge; the first bridge at the site was built in 1816. The 700 ft (210 m) Main Street Bridge opened on July 30, 2010. The bridge has three lanes for vehicular traffic (one westbound and two eastbound) and another separated lane for pedestrians and bikes. The Rich Street Bridge opened in July 2012 adjacent to the Main Street Bridge, connecting Rich Street on the east side of the river with Town Street on the west. The Lane Avenue Bridge is a cable-stayed bridge that opened on November 14, 2003, in the University District. The bridge spans the Olentangy River with three lanes of traffic each way.
The city's primary airport, John Glenn Columbus International Airport, is on the city's east side. Formerly known as Port Columbus, John Glenn provides service to Toronto, Ontario, Canada, and Cancun, Mexico (on a seasonal basis), as well as to most domestic destinations, including all the major hubs along with San Francisco, Salt Lake City and Seattle. The airport was a hub for discount carrier Skybus Airlines and continues to be home to NetJets, the world's largest fractional ownership air carrier. According to a 2005 market survey, John Glenn Columbus International Airport attracts about 50% of its passengers from outside of its 60-mile (97 km) radius primary service region. It is the 52nd-busiest airport in the United States by total passenger boardings.
Rickenbacker International Airport, in southern Franklin County, is a major cargo facility that is used by the Ohio Air National Guard. Allegiant Air offers nonstop service from Rickenbacker to Florida destinations. Ohio State University Don Scott Airport and Bolton Field are other large general-aviation facilities in the Columbus area.
In 1907, 14-year-old Cromwell Dixon built the SkyCycle, a pedal-powered blimp, which he flew at Driving Park. Three years later, one of the Wright brothers' exhibition pilots, Phillip Parmalee, conducted the world's first commercial cargo flight when he flew two packages containing 88 kilograms of silk 70 miles (110 km) from Dayton to Columbus in a Wright Model B.
Military aviators from Columbus distinguished themselves during World War I. Six Columbus pilots, led by top ace Eddie Rickenbacker, achieved 42 "kills" – a full 10% of all US aerial victories in the war, and more than the aviators of any other American city.
After the war, Port Columbus Airport (now known as John Glenn Columbus International Airport) became the axis of a coordinated rail-to-air transcontinental system that moved passengers from the East Coast to the West. TAT, which later became TWA, provided commercial service, following Charles Lindbergh's promotion of Columbus to the nation for such a hub. Following the failure of a bond levy in 1927 to build the airport, Lindbergh campaigned in the city in 1928, and the next bond levy passed that year. On July 8, 1929, the airport opened for business with the inaugural TAT westbound flight from Columbus to Waynoka, Oklahoma. Among the 19 passengers on that flight was Amelia Earhart, with Henry Ford and Harvey Firestone attending the opening ceremonies.
In 1964, Ohio native Geraldine Fredritz Mock became the first woman to fly solo around the world, leaving from Columbus and piloting the Spirit of Columbus. Her flight lasted nearly a month and set a record for speed for planes under 3,858 pounds (1,750 kg).
Columbus maintains a widespread municipal bus service called the Central Ohio Transit Authority (COTA). The service operates 41 routes with a fleet of 440 buses, serving approximately 19 million passengers per year. COTA operates 23 regular fixed-service routes, 14 express services, a bus rapid transit route, a free downtown circulator, night service, an airport connector and other services. LinkUS, an initiative between COTA, the city, and the Mid-Ohio Regional Planning Commission, is planning to add more rapid transit to Columbus, with three proposed corridors operating by 2030, and potentially a total of five by 2050.
Intercity bus service is provided at the Columbus Bus Station by Greyhound, Barons Bus Lines, Miller Transportation, GoBus and other carriers.
Columbus does not have passenger rail service. The city's major train station, Union Station, was a stop along Amtrak's National Limited train service until 1977 and was razed in 1979, and the Greater Columbus Convention Center now stands in its place. Until Amtrak's founding in 1971, the Penn Central ran the Cincinnati Limited to Cincinnati to the southwest (in prior years the train continued to New York City to the east); the Ohio State Limited between Cincinnati and Cleveland, with Union Station serving as a major intermediate stop (the train going unnamed between 1967 and 1971); and the Spirit of St. Louis, which ran between St. Louis and New York City until 1971. The station was also a stop along the Pennsylvania Railroad, the New York Central Railroad, the Chesapeake and Ohio Railway, the Baltimore and Ohio Railroad, the Norfolk and Western Railway, the Cleveland, Columbus and Cincinnati Railroad, and the Pittsburgh, Cincinnati, Chicago and St. Louis Railroad. As the city lacks local, commuter or intercity trains, Columbus is now the largest city and metropolitan area in the U.S. without any passenger rail service. Numerous proposals to return rail service have been introduced; currently Amtrak plans to restore service to Columbus by 2035.
Cycling as transportation is steadily increasing in Columbus with its relatively flat terrain, intact urban neighborhoods, large student population and off-road bike paths. The city has put forth the 2012 Bicentennial Bikeways Plan, as well as a move toward a Complete Streets policy. Grassroots efforts such as Bike to Work Week, Consider Biking, Yay Bikes, Third Hand Bicycle Co-op, Franklinton Cycleworks and Cranksters, a local radio program focused on urban cycling, have contributed to cycling as transportation.
Columbus also hosts urban cycling "off-shots" with messenger-style "alleycat" races, as well as unorganized group rides, a monthly Critical Mass ride, bicycle polo, art showings, movie nights and a variety of bicycle-friendly businesses and events throughout the year. All this activity occurs despite Columbus's frequently inclement weather.
The Main Street Bridge, opened in 2010, features a dedicated bike and pedestrian lane separated from traffic.
The city has its own public bicycle system. CoGo Bike Share has a network of about 600 bicycles and 80 docking stations. PBSC Urban Solutions, a company based in Canada, supplies technology and equipment. Bird electric scooters have also been introduced.
The city of Columbus has a higher-than-average percentage of households without a car. In 2015, 9.8% of Columbus households lacked a car, a number that fell slightly to 9.4% in 2016. The national average was 8.7% in 2016. Columbus averaged 1.55 cars per household in 2016, compared to a national average of 1.8.
Columbus has 10 sister cities as designated by Sister Cities International. Columbus established its first sister city relationship in 1955 with Genoa, Italy. To commemorate this relationship, Columbus received as a gift from the people of Genoa, a bronze statue of Christopher Columbus. The statue overlooked Broad Street in front of Columbus City Hall from 1955 to 2020; it was removed during the George Floyd protests.

Fighting for control of the territory in the French and Indian War (1754-1763) became part of the international Seven Years' War (1756-1763). During this period, the region routinely suffered turmoil, massacres and battles. The 1763 Treaty of Paris ceded the Ohio Country to the British Empire.",

The tribes resisted expansion by the fledgling United States, leading to years of bitter conflict. The decisive Battle of Fallen Timbers resulted in the Treaty of Greenville in 1795, which finally opened the way for new settlements. By 1797, a young surveyor from Virginia named Lucas Sullivant had founded a permanent settlement on the west bank of the forks of the Scioto and Olentangy rivers. An admirer of Benjamin Franklin, Sullivant chose to name his frontier village \"Franklinton.\" The location was desirable for its proximity to the navigable rivers – but Sullivant was initially foiled when, in 1798, a large flood wiped out the new settlement. He persevered, and the village was rebuilt, though somewhat more inland.",

Built of Columbus limestone from the Marble Cliff Quarry Co., the Statehouse stands on foundations 18 feet (5.5 m) deep that were laid by prison labor gangs rumored to have been composed largely of masons jailed for minor infractions. It features a central recessed porch with a colonnade of a forthright and primitive Greek Doric mode. A broad and low central pediment supports the windowed astylar drum under an invisibly low saucer dome that lights the interior rotunda. There are several artworks within and outside the building, including the William McKinley Monument dedicated in 1907. Unlike many U.S. state capitol buildings, the Ohio State Capitol owes little to the architecture of the national Capitol. During the Statehouse's 22-year construction, seven architects were employed. The Statehouse was opened to the legislature and the public in 1857 and completed in 1861, and is located at the intersection of Broad and High streets in downtown Columbus.",

] | Columbus is the capital and most populous city of the U.S. state of Ohio. With a 2020 census population of 905,748, it is the 14th-most populous city in the U.S., the second-most populous city in the Midwest after Chicago, and the third-most populous U.S. state capital after Phoenix, Arizona and Austin, Texas. Columbus is the county seat of Franklin County; it also extends into Delaware and Fairfield counties. It is the core city of the Columbus metropolitan area, which encompasses ten counties in central Ohio. It had a population of 2,138,926 in 2020, making it the largest metropolitan area entirely in Ohio and 32nd-largest metro area in the U.S. Columbus originated as numerous Native American settlements on the banks of the Scioto River. Franklinton, now a city neighborhood, was the first European settlement, laid out in 1797. The city was founded in 1812 at the confluence of the Scioto and Olentangy rivers, and laid out to become the state capital. The city was named for Italian explorer Christopher Columbus. The city assumed the function of state capital in 1816 and county seat in 1824. Amid steady years of growth and industrialization, the city has experienced numerous floods and recessions. Beginning in the 1950s, Columbus began to experience significant growth; it became the largest city in Ohio in land and population by the early 1990s. Growth has continued in the 21st century, with redevelopment occurring in numerous city neighborhoods, including Downtown. The city has a diverse economy based on education, government, insurance, banking, defense, aviation, food, clothes, logistics, steel, energy, medical research, health care, hospitality, retail and technology. The metropolitan area is home to the Battelle Memorial Institute, the world's largest private research and development foundation; Chemical Abstracts Service, the world's largest clearinghouse of chemical information; and the Ohio State University, one of the largest universities in the United States. The Greater Columbus area is further home to the headquarters of six Fortune 500 companies, namely Cardinal Health, American Electric Power, L Brands, Nationwide, Bread Financial and Huntington Bancshares. | 2001-07-28T01:05:07Z | 2023-12-21T10:54:07Z | [

5,951 | Cleveland | Cleveland (/ˈkliːvlənd/ KLEEV-lənd), officially the City of Cleveland, is a city in the U.S. state of Ohio and the county seat of Cuyahoga County. Located in Northeast Ohio along the southern shore of Lake Erie, it is situated across the U.S. maritime border with Canada and lies approximately 60 miles (97 km) west of Pennsylvania. Cleveland ranks as the largest city on Lake Erie, the second-most populous city in Ohio, and the 54th-most populous city in the U.S. with a 2020 population of 372,624. The city anchors the Cleveland metropolitan area, the 33rd-largest in the U.S. at 2.18 million residents, as well as the larger Cleveland–Akron–Canton combined statistical area, the most populous in Ohio and the 17th-largest in the country with a population of 3.63 million in 2020.
Cleveland was founded in 1796 near the mouth of the Cuyahoga River as part of the Connecticut Western Reserve by General Moses Cleaveland, after whom the city was named. Its location on both the river and the lake shore allowed it to grow into a major commercial and industrial metropolis by the late 19th century, attracting large numbers of immigrants and migrants. It was among the top 10 U.S. cities by population for much of the 20th century, a period which saw the development of the city's cultural institutions. By the 1960s, Cleveland's economy began to slow down as manufacturing declined and suburbanization occurred. The city has since developed a diversified economy and gained a national reputation as a center for healthcare and the arts.
Cleveland is a port city, connected to the Atlantic Ocean via the Saint Lawrence Seaway. Its economy relies on diverse sectors that include higher education, manufacturing, financial services, healthcare, and biomedicals. The city serves as the headquarters of the Federal Reserve Bank of Cleveland, as well as several major companies. The GDP for the Greater Cleveland MSA was $135 billion in 2019 (~$153 billion in 2022). Combined with the Akron MSA, the eight-county Cleveland–Akron metropolitan economy was $175 billion in 2019 (~$199 billion in 2022), the largest in Ohio, accounting for 25% of the state's GDP.
Designated as a global city by the Globalization and World Cities Research Network, Cleveland is home to several major cultural institutions, including the Cleveland Museum of Art, the Cleveland Museum of Natural History, the Cleveland Public Library, the Cleveland Orchestra, Playhouse Square, and the Rock and Roll Hall of Fame, as well as Case Western Reserve University. Known as "The Forest City" among many other nicknames, Cleveland serves as the center of the Cleveland Metroparks nature reserve system. The city's major league professional sports teams include the Cleveland Browns, the Cleveland Cavaliers, and the Cleveland Guardians.
Cleveland was established on July 22, 1796, by surveyors of the Connecticut Land Company when they laid out Connecticut's Western Reserve into townships and a capital city. They named the new settlement "Cleaveland" after their leader, General Moses Cleaveland, a veteran of the American Revolutionary War. Cleaveland oversaw the New England–style design of the plan for what would become the modern downtown area, centered on Public Square, before returning to Connecticut, never again to visit Ohio. The town's name was often shortened to "Cleveland", even by Cleaveland's original surveyors. A common myth emerged that the spelling was altered by The Cleveland Advertiser in order to fit the name on the newspaper's masthead.
The first permanent European settler in Cleveland was Lorenzo Carter, who built a cabin on the banks of the Cuyahoga River. The emerging community served as an important supply post for the U.S. during the Battle of Lake Erie in the War of 1812. Locals adopted Commodore Oliver Hazard Perry as a civic hero and erected a monument in his honor decades later. Largely through the efforts of the settlement's first lawyer Alfred Kelley, the village of Cleveland was incorporated on December 23, 1814.
In spite of the nearby swampy lowlands and harsh winters, the town's waterfront location proved to be an advantage, giving it access to Great Lakes trade. It grew rapidly after the 1832 completion of the Ohio and Erie Canal. This key link between the Ohio River and the Great Lakes connected Cleveland to the Atlantic Ocean via the Erie Canal and Hudson River, and later via the Saint Lawrence Seaway. The town's growth continued with added railroad links. In 1836, Cleveland, then only on the eastern banks of the Cuyahoga, was officially incorporated as a city, and John W. Willey was elected its first mayor. That same year, it nearly erupted into open warfare with neighboring Ohio City over a bridge connecting the two communities. Ohio City remained an independent municipality until its annexation by Cleveland in 1854.
A center of abolitionist activity, Cleveland (code-named "Station Hope") was a major stop on the Underground Railroad for escaped African American slaves en route to Canada. The city also served as an important center for the Union during the American Civil War. Decades later, in July 1894, the wartime contributions of those serving the Union from Cleveland and Cuyahoga County would be honored with the Soldiers' and Sailors' Monument on Public Square.
The Civil War vaulted Cleveland into the first rank of American manufacturing cities and fueled unprecedented growth. Its prime geographic location as a transportation hub on the Great Lakes played an important role in its development as an industrial and commercial center. In 1870, John D. Rockefeller founded Standard Oil in Cleveland, and in 1885, he moved its headquarters to New York City, which had become a center of finance and business.
Cleveland's economic growth and industrial jobs attracted large waves of immigrants from Southern and Eastern Europe as well as Ireland. Urban growth was accompanied by significant strikes and labor unrest, as workers demanded better wages and working conditions. Between 1881 and 1886, 70 to 80% of strikes were successful in improving labor conditions in Cleveland. The Cleveland Streetcar Strike of 1899 was one of the more violent instances of labor strife in the city during this period.
By 1910, Cleveland had become known as the "Sixth City" due to its status at the time as the sixth-largest U.S. city. Its businesses included automotive companies Peerless, Chandler, and Winton, maker of the first car driven across the U.S. Other manufacturing industries in Cleveland included steam cars produced by White and electric cars produced by Baker. The city counted major Progressive Era politicians among its leaders, most prominently the populist Mayor Tom L. Johnson, who was responsible for the development of the Cleveland Mall Plan. The era of the City Beautiful movement in Cleveland architecture, this period saw wealthy patrons support the establishment of the city's major cultural institutions. The most prominent among them were the Cleveland Museum of Art, which opened in 1916, and the Cleveland Orchestra, established in 1918.
In addition to the large immigrant population, African American migrants from the rural South arrived in Cleveland (among other Northeastern and Midwestern cities) as part of the Great Migration for jobs, constitutional rights, and relief from racial discrimination. By 1920, the year in which the Cleveland Indians won their first World Series championship, Cleveland had grown into a densely-populated metropolis of 796,841, making it the fifth-largest city in the nation, with a foreign-born population of 30%.
At this time, Cleveland saw the rise of radical labor movements, most prominently the Industrial Workers of the World (IWW), in response to the conditions of the largely immigrant and migrant workers. In 1919, the city attracted national attention amid the First Red Scare for the Cleveland May Day Riots, in which local socialist and IWW demonstrators clashed with anti-socialists. The riots occurred during the broader strike wave that swept the U.S. that year.
Cleveland's population continued to grow throughout the Roaring Twenties. The decade saw the establishment of the city's Playhouse Square, and the rise of the risqué Short Vincent. The Bal-Masque balls of the avant-garde Kokoon Arts Club scandalized the city. Jazz came to prominence in Cleveland during this period. Prohibition first took effect in Ohio in May 1919 (although it was not well-enforced in Cleveland), became law with the Volstead Act in 1920, and was eventually repealed nationally by Congress in 1933. The ban on alcohol led to the rise of speakeasies throughout the city and organized crime gangs, such as the Mayfield Road Mob, who smuggled bootleg liquor across Lake Erie from Canada into Cleveland.
The era of the flapper marked the beginning of the golden age in Downtown Cleveland retail, centered on major department stores Higbee's, Bailey's, the May Company, Taylor's, Halle's, and Sterling Lindner Davis, which collectively represented one of the largest and most fashionable shopping districts in the country, often compared to New York's Fifth Avenue. In 1929, Cleveland hosted the first of many National Air Races, and Amelia Earhart flew to the city from Santa Monica, California in the Women's Air Derby. The Van Sweringen brothers commenced construction of the Terminal Tower skyscraper in 1926 and oversaw it to completion in 1927. By the time the building was dedicated as part of Cleveland Union Terminal in 1930, the city had a population of over 900,000.
Cleveland was hit hard by the Wall Street Crash of 1929 and the subsequent Great Depression. A center of union activity, the city saw significant labor struggles in this period, including strikes by workers against Fisher Body in 1936 and against Republic Steel in 1937. The city was also aided by major federal works projects sponsored by President Franklin D. Roosevelt's New Deal. In commemoration of the centennial of Cleveland's incorporation as a city, the Great Lakes Exposition debuted in June 1936 at the city's North Coast Harbor, along the Lake Erie shore north of downtown. Conceived by Cleveland's business leaders as a way to revitalize the city during the Depression, it drew four million visitors in its first season, and seven million by the end of its second and final season in September 1937.
On December 7, 1941, Imperial Japan attacked Pearl Harbor and declared war on the U.S. Two of the victims of the attack were Cleveland natives – Rear Admiral Isaac C. Kidd and ensign William Halloran. The attack signaled America's entry into World War II. A major hub of the "Arsenal of Democracy", Cleveland under Mayor Frank Lausche contributed massively to the U.S. war effort as the fifth largest manufacturing center in the nation. During his tenure, Lausche also oversaw the establishment of the Cleveland Transit System, the predecessor to the Greater Cleveland Regional Transit Authority.
After the war, Cleveland initially experienced an economic boom, and businesses declared the city to be the "best location in the nation". In 1949, the city was named an All-America City for the first time, and in 1950, its population reached 914,808. In sports, the Indians won the 1948 World Series, the hockey team, the Barons, became champions of the American Hockey League, and the Browns dominated professional football in the 1950s. As a result, along with track and boxing champions produced, Cleveland was declared the "City of Champions" in sports at this time. Additionally, the 1950s saw the rising popularity of a new music genre that local WJW (AM) disc jockey Alan Freed dubbed "rock and roll".
However, by the 1960s, Cleveland's economy began to slow down, and residents increasingly sought new housing in the suburbs, reflecting the national trends of suburban growth following federally subsidized highways. Industrial restructuring, particularly in the steel and automotive industries, resulted in the loss of numerous jobs in Cleveland and the region, and the city suffered economically. The burning of the Cuyahoga River in June 1969 brought national attention to the issue of industrial pollution in Cleveland and served as a catalyst for the American environmental movement.
Housing discrimination and redlining against African Americans led to racial unrest in Cleveland and numerous other Northern U.S. cities. In Cleveland, the Hough riots erupted from July 18 to 23, 1966, and the Glenville Shootout took place from July 23 to 25, 1968. In November 1967, Cleveland became the first major American city to elect an African American mayor, Carl B. Stokes, who served from 1968 to 1971 and played an instrumental role in restoring the Cuyahoga River.
In December 1978, during the turbulent tenure of Dennis Kucinich as mayor, Cleveland became the first major American city since the Great Depression to enter into a financial default on federal loans. The national recession of the early 1980s "further eroded the city's traditional economic base." While unemployment during the period peaked in 1983, Cleveland's rate of 13.8% was higher than the national average due to the closure of several steel production centers.
The city began a gradual economic recovery under Mayor George V. Voinovich in the 1980s. Downtown saw the construction of the Key Tower and 200 Public Square skyscrapers, as well as the development of the Gateway District – consisting of Progressive Field and Rocket Mortgage FieldHouse – and North Coast Harbor, including the Rock and Roll Hall of Fame, Cleveland Browns Stadium, and the Great Lakes Science Center. Although the city emerged from default in 1987, it later suffered from the impact of the subprime mortgage crisis and the Great Recession.
Nevertheless, by the turn of the 21st century, Cleveland succeeded in developing a more diversified economy and gained a national reputation as a center for healthcare and the arts. The city's downtown and several neighborhoods have experienced significant population growth since 2010, while overall population decline has slowed. Challenges remain for the city, with economic development of neighborhoods, improvement of city schools, and continued efforts to tackle poverty, homelessness, and urban blight being top municipal priorities.
According to the United States Census Bureau, the city has a total area of 82.47 square miles (213.60 km), of which 77.70 square miles (201.24 km) is land and 4.77 square miles (12.35 km) is water. The shore of Lake Erie is 569 feet (173 m) above sea level; however, the city lies on a series of irregular bluffs lying roughly parallel to the lake. In Cleveland these bluffs are cut principally by the Cuyahoga River, Big Creek, and Euclid Creek.
The land rises quickly from the lake shore elevation of 569 feet. Public Square, less than one mile (1.6 km) inland, sits at an elevation of 650 feet (198 m), and Hopkins Airport, 5 miles (8 km) inland from the lake, is at an elevation of 791 feet (241 m).
Cleveland borders several inner-ring and streetcar suburbs. To the west, it borders Lakewood, Rocky River, and Fairview Park, and to the east, it borders Shaker Heights, Cleveland Heights, South Euclid, and East Cleveland. To the southwest, it borders Linndale, Brooklyn, Parma, and Brook Park. To the south, the city borders Newburgh Heights, Cuyahoga Heights, and Brooklyn Heights and to the southeast, it borders Warrensville Heights, Maple Heights, and Garfield Heights. To the northeast, along the shore of Lake Erie, Cleveland borders Bratenahl and Euclid.
Cleveland's downtown architecture is diverse. Many of the city's government and civic buildings, including City Hall, the Cuyahoga County Courthouse, the Cleveland Public Library, and Public Auditorium, are clustered around the open Cleveland Mall and share a common neoclassical architecture. They were built in the early 20th century as the result of the 1903 Group Plan. They constitute one of the most complete examples of City Beautiful design in the U.S.
Completed in 1927 and dedicated in 1930 as part of the Cleveland Union Terminal complex, the Terminal Tower was the tallest building in North America outside New York City until 1964 and the tallest in the city until 1991. It is a prototypical Beaux-Arts skyscraper. The two newer skyscrapers on Public Square, Key Tower (currently the tallest building in Ohio) and the 200 Public Square, combine elements of Art Deco architecture with postmodern designs. Other Cleveland architectural landmarks include the Cleveland Trust Company Building, completed in 1907 and renovated in 2015 as a downtown Heinen's supermarket, and the Cleveland Arcade (sometimes called the Old Arcade), a five-story arcade built in 1890 and renovated in 2001 as a Hyatt Regency Hotel.
Running east from Public Square through University Circle is Euclid Avenue, which was known for its prestige and elegance as a residential street. In the late 1880s, writer Bayard Taylor described it as "the most beautiful street in the world". Known as "Millionaires' Row", Euclid Avenue was world-renowned as the home of such major figures as John D. Rockefeller, Mark Hanna, and John Hay.
Cleveland's historic ecclesiastical architecture includes the Presbyterian Old Stone Church in downtown Cleveland and the onion domed St. Theodosius Russian Orthodox Cathedral in Tremont, along with myriad ethnically inspired Roman Catholic churches.
The Cleveland City Planning Commission has officially designated 34 neighborhoods in Cleveland. Centered on Public Square, Downtown Cleveland is the city's central business district, encompassing a wide range of subdistricts, such as the Nine-Twelve District, the Campus District, the Civic Center, East 4th Street, and Playhouse Square. It also historically included the lively Short Vincent entertainment district, which attracted both notorious mobsters like Shondor Birns and visiting celebrities like Frank Sinatra and Lauren Bacall. Mixed-use areas, such as the Warehouse District and the Superior Arts District, are occupied by industrial and office buildings as well as restaurants, cafes, and bars. The number of condominiums, lofts, and apartments has been on the increase since 2000 and especially 2010, reflecting downtown's growing population.
Clevelanders geographically define themselves in terms of whether they live on the east or west side of the Cuyahoga River. The East Side includes the neighborhoods of Buckeye–Shaker, Buckeye–Woodhill, Central, Collinwood (including Nottingham), Euclid–Green, Fairfax, Glenville, Goodrich–Kirtland Park (including Asiatown), Hough, Kinsman, Lee–Miles (including Lee–Harvard and Lee–Seville), Mount Pleasant, St. Clair–Superior, Union–Miles Park, and University Circle (including Little Italy). The West Side includes the neighborhoods of Brooklyn Centre, Clark–Fulton, Cudell, Detroit–Shoreway, Edgewater, Ohio City, Old Brooklyn, Stockyards, Tremont (including Duck Island), West Boulevard, and the four neighborhoods colloquially known as West Park: Kamm's Corners, Jefferson, Bellaire–Puritas, and Hopkins. The Cuyahoga Valley neighborhood (including the Flats) is situated between the East and West Sides, while Broadway–Slavic Village is sometimes referred to as the South Side.
Several neighborhoods have begun to attract the return of the middle class that left the city for the suburbs in the 1960s and 1970s. These neighborhoods are on both the West Side (Ohio City, Tremont, Detroit–Shoreway, and Edgewater) and the East Side (Collinwood, Hough, Fairfax, and Little Italy). Much of the growth has been spurred on by attracting creative class members, which has facilitated new residential development and the transformation of old industrial buildings into loft spaces for artists.
With its extensive cleanup of its Lake Erie shore and the Cuyahoga River, Cleveland has been recognized by national media as an environmental success story and a national leader in environmental protection. Since the city's industrialization, the Cuyahoga River had become so affected by industrial pollution that it "caught fire" a total of 13 times beginning in 1868. It was the river fire of June 1969 that spurred the city to action under Mayor Carl B. Stokes, and played a key role in the passage of the Clean Water Act in 1972 and the National Environmental Policy Act later that year.
Since that time, the Cuyahoga has been extensively cleaned up through the efforts of the city and the Ohio Environmental Protection Agency (OEPA). In 2019, the American Rivers conservation association named the river "River of the Year" in honor of "50 years of environmental resurgence."
In addition to continued efforts to improve freshwater and air quality, Cleveland is now exploring renewable energy. The city's two main electrical utilities are FirstEnergy and Cleveland Public Power. Its climate action plan, updated in December 2018, has a 2050 target of 100% renewable power, along with reduction of greenhouse gases to 80% below the 2010 level. In recent decades, Cleveland has been working to address the issue of harmful algal blooms on Lake Erie, fed primarily by agricultural runoff, which have presented new environmental challenges for the city and for northern Ohio.
Typical of the Great Lakes region, Cleveland exhibits a continental climate with four distinct seasons, which lies in the humid continental (Köppen Dfa) zone. The climate is transitional with the Cfa humid subtropical climate. Summers are hot and humid, while winters are cold and snowy. East of the mouth of the Cuyahoga, the land elevation rises rapidly in the south. Together with the prevailing winds off Lake Erie, this feature is the principal contributor to the lake-effect snow that is typical in Cleveland (especially on the city's East Side) from mid-November until the surface of the lake freezes, usually in late January or early February. The lake effect causes a relative differential in geographical snowfall totals across the city. On the city's far West Side, the Hopkins neighborhood only reached 100 inches (254 cm) of snowfall in a season three times since record-keeping for snow began in 1893. By contrast, seasonal totals approaching or exceeding 100 inches (254 cm) are not uncommon as the city ascends into the Heights on the east, where the region known as the 'Snow Belt' begins. Extending from the city's East Side and its suburbs, the Snow Belt reaches up the Lake Erie shore as far as Buffalo.
The all-time record high in Cleveland of 104 °F (40 °C) was established on June 25, 1988, and the all-time record low of −20 °F (−29 °C) was set on January 19, 1994. On average, July is the warmest month with a mean temperature of 74.5 °F (23.6 °C), and January, with a mean temperature of 29.1 °F (−1.6 °C), is the coldest. Normal yearly precipitation based on the 30-year average from 1991 to 2020 is 41.03 inches (1,042 mm). The least precipitation occurs on the western side and directly along the lake, and the most occurs in the eastern suburbs. Parts of Geauga County to the east receive over 44 inches (1,100 mm) of liquid precipitation annually.
At the 2020 census, there were 372,624 people and 170,549 households in Cleveland. The population density was 4,901.51 inhabitants per square mile (1,892.5/km). The median household income was $30,907 and the per capita income was $21,223. 32.7% of the population was living below the poverty line. Of the city's population over the age of 25, 17.5% held a bachelor's degree or higher, and 80.8% had a high school diploma or equivalent. The median age was 36.6 years.
As of 2020, the racial composition of the city was 47.5% African American, 32.1% non-Hispanic white, 13.1% Hispanic or Latino, 2.8% Asian and Pacific Islander, 0.2% Native American, and 3.8% from two or more races. 85.3% of Clevelanders age five and older spoke English at home as a primary language. 14.7% spoke a foreign language, including Spanish, Arabic, Chinese, Albanian, and various Slavic languages (Russian, Polish, Serbian, Croatian, and Slovene). The city's spoken accent is an advanced form of Inland Northern American English, similar to other Great Lakes cities, but distinctive from the rest of Ohio.
In the 19th and early 20th centuries, Cleveland saw a massive influx of immigrants from Ireland, Italy, and the Austro-Hungarian, German, Russian, and Ottoman empires, most of whom were attracted by manufacturing jobs. As a result, Cleveland and Cuyahoga County today have substantial communities of Irish (especially in West Park), Italians (especially in Little Italy), Germans, and several Central-Eastern European ethnicities, including Czechs, Hungarians, Lithuanians, Poles, Romanians, Russians, Rusyns, Slovaks, Ukrainians, and ex-Yugoslav groups, such as Slovenes, Croats and Serbs. The presence of Hungarians within Cleveland proper was, at one time, so great that the city boasted the highest concentration of Hungarians in the world outside of Budapest. Cleveland has a long-established Jewish community, historically centered on the East Side neighborhoods of Glenville and Kinsman, but now mostly concentrated in East Side suburbs such as Cleveland Heights and Beachwood, location of the Maltz Museum of Jewish Heritage.
The availability of jobs attracted African Americans from the South. Between 1910 and 1970, the black population of Cleveland, largely concentrated on the city's East Side, increased significantly as a result of the First and Second Great Migrations. Cleveland's Latino community consists primarily of Puerto Ricans, as well as smaller numbers of immigrants from Mexico, Cuba, the Dominican Republic, South and Central America, and Spain. The city's Asian community, centered on historical Asiatown, consists of Chinese, Koreans, Vietnamese, and other groups. Additionally, the city and the county have significant communities of Albanians, Arabs (especially Lebanese, Syrians, and Palestinians), Armenians, French, Greeks, Iranians, Scots, Turks, and West Indians. A 2020 analysis found Cleveland to be the most ethnically and racially diverse major city in Ohio.
The influx of immigrants in the 19th and early 20th centuries drastically transformed Cleveland's religious landscape. From a homogeneous settlement of New England Protestants, it evolved into a city with a diverse religious composition. The predominant faith among Clevelanders today is Christianity (Catholic, Protestant, and Eastern and Oriental Orthodox), with Jewish, Muslim, Hindu, and Buddhist minorities.
Within Cleveland, the neighborhoods with the highest foreign-born populations are Asiatown/Goodrich–Kirtland Park (32.7%), Clark–Fulton (26.7%), West Boulevard (18.5%), Brooklyn Centre (17.3%), Downtown (17.2%), University Circle (15.9%, with 20% in Little Italy), and Jefferson (14.3%). Recent waves of immigration have brought new groups to Cleveland, including Ethiopians and South Asians, as well as immigrants from Russia and the former USSR, Southeast Europe (especially Albania), the Middle East, East Asia, and Latin America. In the 2010s, the immigrant population of Cleveland and Cuyahoga County began to see significant growth, becoming a major center for immigration in the Great Lakes region. A 2019 study found Cleveland to be the city with the shortest average processing time in the nation for immigrants to become U.S. citizens. The city's annual One World Day in Rockefeller Park includes a naturalization ceremony of new immigrants.
Cleveland's location on the Cuyahoga River and Lake Erie has been key to its growth as a major commercial center. Steel and many other manufactured goods emerged as leading industries. The city has since diversified its economy in addition to its manufacturing sector.
Established in 1914, the Federal Reserve Bank of Cleveland is one of 12 U.S. Federal Reserve Banks. Its downtown building, located on East 6th Street and Superior Avenue, was completed in 1923 by the Cleveland architectural firm Walker and Weeks. The headquarters of the Federal Reserve System's Fourth District, the bank employs 1,000 people and maintains branch offices in Cincinnati and Pittsburgh. The president and CEO is Loretta Mester.
Cleveland and Cuyahoga County are home to the corporate headquarters of Fortune 500 companies Cleveland-Cliffs, Progressive, Sherwin-Williams, Parker-Hannifin, KeyCorp, and Travel Centers of America. Other large companies based in the city and the county include Aleris, American Greetings, Applied Industrial Technologies, Eaton, Forest City Realty Trust, Heinen's Fine Foods, Hyster-Yale Materials Handling, Lincoln Electric, Medical Mutual of Ohio, Moen Incorporated, NACCO Industries, Nordson Corporation, OM Group, Swagelok, Kirby Company, Things Remembered, Third Federal S&L, TransDigm Group, and Vitamix. NASA maintains the Glenn Research Center in Cleveland. Jones Day, one of the largest law firms in the U.S., was founded in Cleveland in 1893.
Healthcare plays a major role in Cleveland's economy. The city's "Big Three" hospital systems are the Cleveland Clinic, University Hospitals, and MetroHealth. The Cleveland Clinic is the largest private employer in the city of Cleveland and the state of Ohio, with a workforce of over 55,000 as of 2022. It carries the distinction as being among America's best hospitals with top ratings published in U.S. News & World Report. The clinic is led by Croatian-born president and CEO Tomislav Mihaljevic and it is affiliated with Case Western Reserve University School of Medicine.
University Hospitals includes the University Hospitals Cleveland Medical Center and its Rainbow Babies & Children's Hospital. Cliff Megerian serves as that system's CEO. MetroHealth on the city's west side is led by president and CEO Airica Steed. Formerly known as City Hospital, it operates one of two Level I trauma centers in the city, and has various locations throughout Greater Cleveland.
In 2013, Cleveland's Global Center for Health Innovation opened with 235,000 square feet (21,800 m) of display space for healthcare companies across the world. To take advantage of the proximity of universities and other medical centers in Cleveland, the Veterans Administration moved the region's VA hospital from suburban Brecksville to a new facility in University Circle.
Cleveland's Playhouse Square is the second largest performing arts center in the U.S. behind New York City's Lincoln Center. It includes the State, Palace, Allen, Hanna, and Ohio theaters. The theaters host Broadway musicals, special concerts, speaking engagements, and other events throughout the year. Playhouse Square's resident performing arts companies include Cleveland Ballet, the Cleveland International Film Festival, the Cleveland Play House, Cleveland State University Department of Theatre and Dance, DANCECleveland, the Great Lakes Theater Festival, and the Tri-C Jazz Fest. A city with strong traditions in theater and vaudeville, Cleveland has produced many renowned performers, most prominently comedian Bob Hope.
Outside Playhouse Square is Karamu House, the oldest African American theater in the nation, established in 1915. On the West Side, the Gordon Square Arts District in the Detroit–Shoreway neighborhood is the location of the Capitol Theatre, the Near West Theatre, and an Off-Off-Broadway playhouse, the Cleveland Public Theatre. The Dobama Theatre and the Beck Center for the Arts are based in Cleveland's streetcar suburbs of Cleveland Heights and Lakewood respectively.
The Cleveland Orchestra is widely considered one of the world's finest orchestras, and often referred to as the finest in the nation. It is one of the "Big Five" major orchestras in the United States. The orchestra plays at Severance Hall in University Circle during the winter and at Blossom Music Center in Cuyahoga Falls during the summer. The city is also home to the Cleveland Pops Orchestra, the Cleveland Youth Orchestra, the Contemporary Youth Orchestra, the Cleveland Youth Wind Symphony, and the biennial Cleveland International Piano Competition which has, in the past, often featured the Cleveland Orchestra.
One Playhouse Square, now the headquarters for Cleveland's public broadcasters, was initially used as the broadcast studios of WJW (AM), where disc jockey Alan Freed first popularized the term "rock and roll". Beginning in the 1950s, Cleveland gained a strong reputation as a key breakout market for rock music. Its popularity in the city was so great that Billy Bass, the program director at the WMMS radio station, referred to Cleveland as "The Rock and Roll Capital of the World". The Cleveland Agora Theatre and Ballroom has served as a major venue for rock concerts in the city since the 1960s. From 1974 through 1980, the city hosted the World Series of Rock at Cleveland Municipal Stadium.
Jazz and R&B have a long history in Cleveland. Many major figures in jazz performed in the city, including Louis Armstrong, Cab Calloway, Duke Ellington, Ella Fitzgerald, Dizzy Gillespie, and Billie Holiday. Legendary pianist Art Tatum regularly played in Cleveland clubs in the 1930s, and gypsy jazz guitarist Django Reinhardt gave his U.S. debut performance in Cleveland in 1946. Prominent jazz artist Noble Sissle was a graduate of Cleveland Central High School, and Artie Shaw worked and performed in Cleveland early in his career. The Tri-C Jazz Fest has been held annually in Cleveland at Playhouse Square since 1980, and the Cleveland Jazz Orchestra was established in 1984. Joe Siebert's documentary film The Sax Man on the life of Cleveland street saxophonist Maurice Reedus Jr. was released in 2014.
The city has a history of polka music being popular both past and present and is the location of the Polka Hall of Fame. There is even a subgenre called Cleveland-style polka, named after the city. The music's popularity is due in part to the success of Frankie Yankovic, a Cleveland native who was considered "America's Polka King".
There is a significant hip hop music scene in Cleveland. In 1997, the Cleveland hip hop group Bone Thugs-n-Harmony won a Grammy for their song "Tha Crossroads".
The first film shot in Cleveland was in 1897 by the company of Ohioan Thomas Edison. Before Hollywood became the center for American cinema, filmmaker Samuel R. Brodsky and playwright Robert H. McLaughlin operated a film studio at the Andrews mansion on Euclid Avenue (now the WEWS-TV studio). There they produced major silent-era features, such as Dangerous Toys (1921), which are now considered lost. Brodsky also directed the weekly Plain Dealer Screen Magazine that ran in theaters in Cleveland and Ohio from 1917 to 1924. In addition, Cleveland hosted over a dozen sponsored film studios, including Cinécraft Productions, which still operates in Ohio City.
In the "talkie" era, Cleveland featured in several major studio films, such as Howard Hawks's Ceiling Zero (1936) with James Cagney and Pat O'Brien. Michael Curtiz's pre-Code classic Goodbye Again (1933) with Warren William and Joan Blondell was set in Cleveland, and players from the 1948 Cleveland Indians appeared in The Kid from Cleveland (1949). Billy Wilder's The Fortune Cookie (1966) was set and filmed in the city and marked the first onscreen pairing of Walter Matthau and Jack Lemmon. Labor struggles in Cleveland were depicted in Native Land (1942), narrated by Paul Robeson, and in Norman Jewison's F.I.S.T. (1978) with Sylvester Stallone. Clevelander Jim Jarmusch's Stranger Than Paradise (1984) – a deadpan comedy about two New Yorkers who travel to Florida by way of Cleveland – was a favorite of the Cannes Film Festival. Major League (1989) reflected the perennial struggles of the Cleveland Indians, while American Splendor (2003) reflected the life of Cleveland graphic novelist Harvey Pekar. Kill the Irishman (2011) depicted the 1970s turf war between Danny Greene and the Cleveland crime family.
Cleveland has doubled for other locations in films. The wedding and reception scenes in The Deer Hunter (1978), while set in the Pittsburgh suburb of Clairton, were shot in Cleveland's Tremont neighborhood. A Christmas Story (1983) was set in Indiana, but drew many external shots from Cleveland. The opening shots of Air Force One (1997) were filmed in and above Severance Hall, and Downtown Cleveland doubled for Manhattan in Spider-Man 3 (2007), The Avengers (2012), and The Fate of the Furious (2017). More recently, Judas and the Black Messiah (2021), though set in Chicago, was filmed in Cleveland. Future productions are handled by the Greater Cleveland Film Commission at the Leader Building on Superior Avenue.
In television, the city is the setting for the popular network sitcom The Drew Carey Show, starring Cleveland native Drew Carey. Hot in Cleveland, a comedy that aired on TV Land, premiered on June 16, 2010, and ran for six seasons until its finale on June 3, 2015. Cleveland Hustles, the CNBC reality show co-created by LeBron James, was filmed in the city.
Cleveland has a thriving literary and poetry community, with regular poetry readings at bookstores, coffee shops, and various other venues. In 1925, Russian Futurist poet Vladimir Mayakovsky came to Cleveland and gave a poetry recitation to the city's ethnic working class, as part of his trip to America. The Cleveland State University Poetry Center serves as an academic center for poetry in the city.
Langston Hughes, preeminent poet of the Harlem Renaissance and child of an itinerant couple, lived in Cleveland as a teenager and attended Central High School in Cleveland in the 1910s. At Central High, the young writer was taught by Helen Maria Chesnutt, daughter of Cleveland-born African American novelist Charles W. Chesnutt. Hughes authored some of his earliest poems, plays, and short stories in Cleveland and contributed to the school newspaper. The African American avant-garde poet Russell Atkins lived in the city as well.
The American modernist poet Hart Crane was born in nearby Garrettsville, Ohio in 1899. His adolescence was divided between Cleveland and Akron before he moved to New York City in 1916. Aside from factory work during World War I, he served as a reporter to The Plain Dealer for a short period, before achieving recognition in the Modernist literary scene. On the Case Western Reserve University campus, a statue of Crane, designed by sculptor William McVey, stands behind the Kelvin Smith Library.
Cleveland was the home of Joe Shuster and Jerry Siegel, who created the comic book character Superman in 1932. Both attended Glenville High School, and their early collaborations resulted in the creation of "The Man of Steel". Harlan Ellison, noted author of speculative fiction, was born in Cleveland in 1934; his family subsequently moved to nearby Painesville, though Ellison moved back to Cleveland in 1949. As a young man, he published a series of short stories appearing in the Cleveland News, and performed in a number of productions for the Cleveland Play House.
Cleveland is the site of the Anisfield-Wolf Book Award, established by poet and philanthropist Edith Anisfield Wolf in 1935, which recognizes books that have made important contributions to the understanding of racism and human diversity. Presented by the Cleveland Foundation, it remains the only American book prize focusing on works that address racism and diversity.
Cleveland has two main art museums. The Cleveland Museum of Art is a major American art museum, with a collection that includes more than 60,000 works of art ranging from ancient masterpieces to contemporary pieces. The Museum of Contemporary Art Cleveland showcases established and emerging artists, particularly from the Cleveland area, through hosting and producing temporary exhibitions. Both museums offer free admission to visitors, with the Cleveland Museum of Art declaring their museum free and open "for the benefit of all the people forever."

Since 1946, the city has annually marked One World Day in the Cleveland Cultural Gardens in Rockefeller Park, celebrating all of its ethnic communities.
Cleveland's mosaic of ethnic communities and their various culinary traditions have long played an important role in defining the city's cuisine. Local mainstays include an abundance of Slavic, Hungarian, and Central-Eastern European contributions, such as kielbasa, stuffed cabbage, pierogies, goulash, and chicken paprikash. German, Irish, Jewish, and Italian American cuisines are also prominent in Cleveland, as are Lebanese, Greek, Chinese, Puerto Rican, Mexican, and numerous other ethnic cuisines.

Major League
Minor League
Cleveland's major professional sports teams are the Cleveland Guardians (Major League Baseball), the Cleveland Browns (National Football League), and the Cleveland Cavaliers (National Basketball Association). Other professional teams include the Cleveland Monsters (American Hockey League), the Cleveland Charge (NBA G League), the Cleveland Crunch (Major League Indoor Soccer), Cleveland SC (National Premier Soccer League), and the Cleveland Fusion (Women's Football Alliance). Local sporting venues include Progressive Field, Cleveland Browns Stadium, Rocket Mortgage FieldHouse, the Wolstein Center, and the I-X Center.
The Cleveland Guardians – known as the Indians from 1915 to 2021 – won the World Series in 1920 and 1948. They also won the American League pennant, making the World Series in the 1954, 1995, 1997, and 2016 seasons. Between 1995 and 2001, Jacobs Field (now known as Progressive Field) sold out 455 consecutive games, a Major League Baseball record until it was broken in 2008.
Historically, the Browns have been among the most successful franchises in American football history, winning eight titles during a short period of time – 1946, 1947, 1948, 1949, 1950, 1954, 1955, and 1964. The Browns have never played in a Super Bowl, getting close five times by making it to the NFL/AFC Championship Game in 1968, 1969, 1986, 1987, and 1989. Former owner Art Modell's relocation of the Browns after the 1995 season (to Baltimore creating the Ravens), caused tremendous heartbreak and resentment among local fans. Cleveland mayor, Michael R. White, worked with the NFL and Commissioner Paul Tagliabue to bring back the Browns beginning in the 1999 season, retaining all team history. In Cleveland's earlier football history, the Cleveland Bulldogs won the NFL Championship in 1924, and the Cleveland Rams won the NFL Championship in 1945 before relocating to Los Angeles.
The Cavaliers won the Eastern Conference in 2007, 2015, 2016, 2017 and 2018 but were defeated in the NBA Finals by the San Antonio Spurs and then by the Golden State Warriors, respectively. The Cavs won the Conference again in 2016 and won their first NBA Championship coming back from a 3–1 deficit, finally defeating the Golden State Warriors. Afterwards, over 1.3 million people attended a parade held in the Cavs' honor on June 22, 2016, in Downtown Cleveland. Previously, the Cleveland Rosenblums dominated the original American Basketball League, and the Cleveland Pipers, owned by George Steinbrenner, won the American Basketball League championship in 1962.
The Cleveland Monsters of the American Hockey League won the 2016 Calder Cup. They were the first Cleveland AHL team to do so since the 1964 Barons.

Known locally as the "Emerald Necklace", the Olmsted-inspired Cleveland Metroparks encircle Cleveland and Cuyahoga County. The city proper encompasses the Metroparks' Brookside and Lakefront Reservations, as well as significant parts of the Rocky River, Washington, and Euclid Creek Reservations. The Lakefront Reservation, which provides public access to Lake Erie, consists of four parks: Edgewater Park, Whiskey Island–Wendy Park, East 55th Street Marina, and Gordon Park.
Three more parks fall under the jurisdiction of the Euclid Creek Reservation: Euclid Beach, Villa Angela, and Wildwood Marina. Further south, bike and hiking trails in the Brecksville and Bedford Reservations, along with Garfield Park, provide access to trails in the Cuyahoga Valley National Park. Also included in the Metroparks system is the Cleveland Metroparks Zoo, established in 1882. Located in Big Creek Valley, the zoo has one of the largest collections of primates in North America.
In addition to the Metroparks, the Cleveland Public Parks District oversees the city's neighborhood parks, the largest of which is the historic Rockefeller Park. The latter is notable for its late 19th century landmark bridges, the Rockefeller Park Greenhouse, and the Cleveland Cultural Gardens, which celebrate the city's ethnic diversity. Just outside of Rockefeller Park, the Cleveland Botanical Garden in University Circle, established in 1930, is the oldest civic garden center in the nation. In addition, the Greater Cleveland Aquarium, located in the historic FirstEnergy Powerhouse in the Flats, is the only independent, free-standing aquarium in the state of Ohio.
Cleveland operates on a mayor–council (strong mayor) form of government, in which the mayor is the chief executive and Cleveland City Council serves as the legislative branch. City council members are elected from 17 wards to four-year terms. From 1924 to 1931, the city briefly experimented with a council–manager government under William R. Hopkins and Daniel E. Morgan before returning to the mayor–council system.
Cleveland is served by Cleveland Municipal Court, the first municipal court in the state. The city also anchors the U.S. District Court for the Northern District of Ohio, based at the Carl B. Stokes U.S. Courthouse and the historic Howard M. Metzenbaum U.S. Courthouse. The Chief Judge for the Northern District is Sara Elizabeth Lioi and the Clerk of Court is Sandy Opacich. The current U.S. Attorney is Rebecca C. Lutzko and the U.S. Marshal is Peter Elliott.
The office of the mayor has been held by Justin Bibb since 2022. Previous mayors include progressive Democrat Tom L. Johnson, World War I-era War Secretary and BakerHostetler founder Newton D. Baker, U.S. Supreme Court Justice Harold Hitz Burton, two-term Ohio Governor and Senator Frank J. Lausche, former U.S. Health, Education, and Welfare Secretary Anthony J. Celebrezze, two-term Ohio Governor and Senator George V. Voinovich, former U.S. Congressman Dennis Kucinich, and Carl B. Stokes, the first African American mayor of a major U.S. city. Frank G. Jackson was the city's longest-serving mayor.
The current Cleveland City Council President is Blaine Griffin, the council Majority Leader is Kerry McCormack, and the Majority Whip is Jasmin Santana. Patricia Britt serves as the Clerk of Council.
Historically, from the Civil War era to the 1940s, Cleveland had been dominated by the Republican Party, with the notable exceptions of the Johnson and Baker mayoral administrations. Businessman and Senator Mark Hanna was among Cleveland's most influential Republican figures, both locally and nationally. Another nationally prominent Ohio Republican, former U.S. President James A. Garfield, was born in Cuyahoga County's Orange Township (today the Cleveland suburb of Moreland Hills). His resting place is the James A. Garfield Memorial in Cleveland's Lake View Cemetery.
Today Cleveland is a major stronghold for the Democratic Party in Ohio. Although local elections are nonpartisan, Democrats still dominate every level of government. Politically, Cleveland and several of its neighboring suburbs comprise Ohio's 11th congressional district. The district is represented by Shontel Brown, one of five Democrats representing the state of Ohio in the U.S. House of Representatives.
Cleveland hosted three Republican national conventions in its history, in 1924, 1936, and 2016. Additionally, the city hosted the Radical Republican convention of 1864. Cleveland has not hosted a national convention for the Democrats, despite the position of Cuyahoga County as a Democratic stronghold in Ohio.
Cleveland has hosted several national election debates, including the second 1980 U.S. presidential debate, the 2004 U.S. vice presidential debate, one 2008 Democratic primary debate, and the first 2020 U.S. presidential debate. Founded in 1912, the City Club of Cleveland provides a platform for national and local debates and discussions. Known as Cleveland's "Citadel of Free Speech", it is one of the oldest continuous independent free speech and debate forums in the country.
Like in other major American cities, crime in Cleveland is concentrated in areas with higher rates of poverty and lower access to jobs. In recent decades, the rate of crime in the city, although higher than the national average, experienced a significant decline, following a nationwide trend in falling crime rates. However, as in other major U.S. cities, crime in Cleveland saw an abrupt rise in 2020–21.
Cleveland's law enforcement agency is the Cleveland Division of Police, established in 1866. The division had 1,400 sworn officers as of 2022, covering five police districts. The district system was introduced in the 1930s by Cleveland Public Safety Director Eliot Ness (of the Untouchables), who later ran for mayor of Cleveland in 1947. The current Chief of Police is Wayne Drummond. In addition, the Cuyahoga County Sheriff's Office is based in Downtown Cleveland at the Justice Center Complex.
In May 2015, Cleveland agreed to a consent decree with the U.S. Department of Justice to revise its policies and implement independent oversight over its police force. In June of that year, Chief U.S. District Judge Solomon Oliver Jr. approved the consent decree, beginning the process of police reform.
Cleveland is served by the firefighters of the Cleveland Division of Fire, established in 1863. The fire department operates out of 22 active fire stations throughout the city in five battalions. Each Battalion is commanded by a Battalion Chief, who reports to an on-duty Assistant Chief.
The Division of Fire operates a fire apparatus fleet of twenty-two engine companies, eight ladder companies, three tower companies, two task force rescue squad companies, hazardous materials ("haz-mat") unit, and numerous other special, support, and reserve units. The current Chief of Department is Anthony Luke.
Cleveland EMS is operated by the city as its own municipal third-service EMS division. Cleveland EMS is the primary provider of Advanced Life Support and ambulance transport within the city of Cleveland, while Cleveland Fire assists by providing fire response medical care. Although a merger between the fire and EMS departments was proposed in the past, the idea was subsequently abandoned.
Cleveland serves as headquarters to Coast Guard District 9 and is responsible for all U.S. Coast Guard operations on the five Great Lakes, the Saint Lawrence Seaway, and surrounding states accumulating 6,700 miles of shoreline and 1,500 miles of international shoreline with Canada. It reports up through the U.S. Department of Homeland Security. Station Cleveland Harbor, located in North Coast Harbor, has a responsibility covering about 550 square miles of the federally navigable waters of Lake Erie, including the Cuyahoga and Rocky rivers, as well as a number of their tributaries.
The Cleveland Metropolitan School District is the second-largest K–12 district in the state of Ohio. It is the only district in Ohio under the direct control of the mayor, who appoints a school board. Approximately 1 square mile (2.6 km) of Cleveland's Buckeye–Shaker neighborhood is part of the Shaker Heights City School District. The area, which has been a part of the Shaker school district since the 1920s, permits these Cleveland residents to pay the same school taxes as the Shaker residents, as well as vote in the Shaker school board elections.
There are several private and parochial schools in Cleveland. These include Benedictine High School, Cleveland Central Catholic High School, Eleanor Gerson School, St. Ignatius High School, St. Joseph Academy, Villa Angela-St. Joseph High School, and St. Martin de Porres.
Cleveland is home to a number of colleges and universities. Most prominent among them is Case Western Reserve University (CWRU), a widely recognized research and teaching institution based in University Circle. A private university with several prominent graduate programs, CWRU was ranked 44th in the nation in 2023 by U.S. News & World Report. University Circle also contains the Cleveland Institute of Art and the Cleveland Institute of Music. Downtown Cleveland is home to Cleveland State University, a public research university with eight constituent colleges, and the metropolitan campus of Cuyahoga Community College. Ohio Technical College is also based in Cleveland. Cleveland's suburban universities and colleges include Baldwin Wallace University in Berea, John Carroll University in University Heights, Ursuline College in Pepper Pike, and Notre Dame College in South Euclid.
Established in 1869, the Cleveland Public Library is one of the largest public libraries in the nation with a collection of over 10 million materials in 2021. Its John G. White Special Collection includes the largest chess library in the world, as well as a significant collection of folklore and rare books on the Middle East and Eurasia. Under head librarian William Howard Brett, the library adopted an "open shelf" philosophy, which allowed patrons open access to the library's bookstacks.
Brett's successor, Linda Eastman, became the first woman ever to lead a major library system in the world. She oversaw the construction of the library's main building on Superior Avenue, designed by Walker and Weeks and opened on May 6, 1925. David Lloyd George, British Prime Minister from 1916 to 1922, laid the cornerstone for the building. The Louis Stokes Wing addition was completed in April 1997. Between 1904 and 1920, 15 libraries built with funds from Andrew Carnegie were opened in the city. Known as the "People's University", the library presently maintains 27 branches. It serves as the headquarters for the CLEVNET library consortium, which includes 47 public library systems in Northeast Ohio.
Cleveland's primary daily newspaper is The Plain Dealer and its associated online publication, Cleveland.com. Defunct major newspapers include the Cleveland Press, an afternoon publication which printed its last edition on June 17, 1982; and the Cleveland News, which ceased publication in 1960. Additional publications include Cleveland Magazine, a regional culture magazine published monthly; Crain's Cleveland Business, a weekly business newspaper; and Cleveland Scene, a free alternative weekly paper which absorbed its competitor, the Cleveland Free Times, in 2008. The digital Belt Magazine was founded in Cleveland in 2013. Time magazine was published in Cleveland for a brief period from 1925 to 1927.
Cleveland's ethnic publications include the Call and Post, a weekly newspaper that primarily serves the city's African American community; the Cleveland Jewish News, a weekly Jewish newspaper; the bi-weekly Russian-language Cleveland Russian Magazine; the Mandarin Erie Chinese Journal; La Gazzetta Italiana in English and Italian; the Ohio Irish American News; and the Spanish language Vocero Latino News. Historically, the Hungarian language newspaper Szabadság served the Hungarian community.
The Cleveland-area television market is served by 11 full power stations, including WKYC (NBC), WEWS-TV (ABC), WJW (Fox), WDLI-TV (Bounce), WOIO (CBS), WVPX-TV (Ion), WVIZ (PBS), WUAB (CW), WRLM (TCT), WBNX-TV (independent), and WQHS-DT (Univision). As of 2021, the market, which includes the Akron and Canton areas, was the 19th-largest in the country, as measured by Nielsen Media Research.
The Mike Douglas Show, a nationally syndicated daytime talk show, began in Cleveland in 1961 on KYW-TV (now WKYC), while The Morning Exchange on WEWS-TV served as the model for Good Morning America. Tim Conway and Ernie Anderson first established themselves in Cleveland while working together at KYW-TV and later WJW-TV (now WJW). Anderson both created and performed as the immensely popular Cleveland horror host Ghoulardi on WJW-TV's Shock Theater, and was later succeeded by the long-running late night duo Big Chuck and Lil' John. Another Anderson protégé – Ron Sweed – would become a popular Cleveland late night movie host in his own right as "The Ghoul".
Cleveland is directly served by 28 full power AM and FM radio stations, 21 of which are licensed to the city. Music stations – which are frequently the highest-rated in the market – include WQAL (hot adult contemporary), WDOK (adult contemporary), WFHM (Christian contemporary), WAKS (contemporary hits), WHLK (adult hits), WMJI (classic hits), WMMS (active rock/hot talk), WNCX (classic rock), WNWV (alternative rock), WGAR-FM (country), WZAK (urban adult contemporary), WENZ (mainstream urban), WJMO (urban gospel), and WCLV (classical/jazz).
News/talk stations include WHK, WTAM, and WERE. During the Golden Age of Radio, WHK was the first radio station to broadcast in Ohio, and one of the first in the country. WTAM is the AM flagship for both the Cleveland Cavaliers and the Cleveland Guardians. Sports stations include WKNR (ESPN), WARF (Fox) and WKRK-FM (CBS), with WKNR and WKRK-FM serving as co-flagship stations for the Cleveland Browns. Religious stations include WHKW, WCCR, and WCRF.
As the regional NPR affiliate, WKSU serves all of Northeast Ohio (including both the Cleveland and Akron markets). College stations include WBWC (Baldwin Wallace), WCSB (Cleveland State), WJCU (John Carroll), and WRUW-FM (Case Western Reserve).
Cleveland has a bus and rail mass transit system operated by the Greater Cleveland Regional Transit Authority (RTA). The rail portion is officially called the RTA Rapid Transit, but local residents refer to it as The Rapid. It consists of three light rail lines, known as the Blue, Green, and Waterfront Lines, and a heavy rail line, the Red Line. In 2008, RTA completed the HealthLine, a bus rapid transit line, for which naming rights were purchased by the Cleveland Clinic and University Hospitals. It runs along Euclid Avenue from downtown through University Circle, ending at the Louis Stokes Station at Windermere in East Cleveland. In 1968, Cleveland became the first city in the nation to have a direct rail transit connection linking the city's downtown to its major airport.
In 2021, Walk Score ranked Cleveland the 17th most walkable of the 50 largest cities in the U.S., with a Walk Score of 57, a Transit Score of 45, and a Bike Score of 55 (out of a maximum of 100). Cleveland's most walkable areas can be found in the Downtown, Ohio City, Detroit–Shoreway, University Circle, and Buckeye–Shaker neighborhoods. Like other major cities, the urban density of Cleveland reduces the need for private vehicle ownership. In 2016, 23.7% of Cleveland households lacked a car, while the national average was 8.7%. Cleveland averaged 1.19 cars per household in 2016, compared to a national average of 1.8.
Cleveland's road system consists of numbered streets running roughly north–south, and named avenues, which run roughly east–west. The numbered streets are designated "east" or "west", depending on where they lie in relation to Ontario Street, which bisects Public Square. The two downtown avenues which span the Cuyahoga change names on the west side of the river. Superior Avenue becomes Detroit Avenue on the West Side, and Carnegie Avenue becomes Lorain Avenue. The bridges that make these connections are the Hope Memorial (Lorain–Carnegie) Bridge and the Veterans Memorial (Detroit–Superior) Bridge.
Cleveland is served by three two-digit interstate highways – Interstate 71, Interstate 77, and Interstate 90 – and by two three-digit interstates – Interstate 480 and Interstate 490. Running due east–west through the West Side suburbs, I-90 turns northeast at the junction with I-490, and is known as the Cleveland Inner Belt. The Cleveland Memorial Shoreway carries Ohio State Route 2 along its length, and at varying points carries US 6, US 20 and I-90. At the junction with the Shoreway, I-90 makes a 90-degree turn in the area known as Dead Man's Curve, then continues northeast. The Jennings Freeway (State Route 176) connects I-71 just south of I-90 to I-480. A third highway, the Berea Freeway (State Route 237 in part), connects I-71 to the airport and forms part of the boundary between Brook Park and Cleveland's Hopkins neighborhood.
Cleveland is a major North American air market, serving 4.93 million people. Cleveland Hopkins International Airport is the city's primary major airport and an international airport that serves the broader region. Originally known as Cleveland Municipal Airport, it was the first municipally owned airport in the country. Cleveland Hopkins is a significant regional air freight hub hosting FedEx Express, UPS Airlines, United States Postal Service, and major commercial freight carriers. In addition to Hopkins, Cleveland is served by Burke Lakefront Airport, on the north shore of downtown between Lake Erie and the Shoreway. Burke is primarily a commuter and business airport.
The Port of Cleveland, at the Cuyahoga River's mouth, is a major bulk freight and container terminal on Lake Erie, receiving much of the raw materials used by the region's manufacturing industries. The Port of Cleveland is the only container port on the Great Lakes with bi-weekly container service between Cleveland and the Port of Antwerp in Belgium on a Dutch service called the Cleveland-Europe Express. In addition to freight, the Port of Cleveland welcomes regional and international tourists who pass through the city on Great Lakes cruises.
Cleveland has a long history as a major railroad hub in the United States. Today, Amtrak provides service to Cleveland, via the Capitol Limited and Lake Shore Limited routes, which stop at Cleveland Lakefront Station. Additionally, Cleveland hosts several inter-modal freight railroad terminals, for Norfolk Southern, CSX and several smaller companies.
National intercity bus service is provided by Greyhound at the station located behind Playhouse Square. Akron Metro, Brunswick Transit Alternative, Laketran, Lorain County Transit, and Medina County Transit provide connecting bus service to the Greater Cleveland Regional Transit Authority. Geauga County Transit and Portage Area Regional Transportation Authority (PARTA) also offer connecting bus service in their neighboring areas.
As of 2023, Cleveland maintains cultural, economic, and educational ties with 28 sister cities around the world. It concluded its first sister city partnership with Lima, Peru, in 1964. In addition, Cleveland hosts the Consulate General of the Republic of Slovenia, which, until Slovene independence in 1991, served as an official consulate for Tito's Yugoslavia. The Cleveland Clinic operates the Cleveland Clinic Abu Dhabi hospital, a sports medicine clinic in Toronto, and a hospital campus in London. The Cleveland Council on World Affairs was established in 1923.
Historically, Cleveland industrialist Cyrus S. Eaton, an apprentice of John D. Rockefeller, played a significant role in promoting dialogue between the U.S. and the USSR during the Cold War. In October 1915 at Cleveland's Bohemian National Hall, Czech American and Slovak American representatives signed the Cleveland Agreement, calling for the formation of a joint Czech and Slovak state. | [

It was among the top 10 U.S. cities by population for much of the 20th century, a period which saw the development of the city's cultural institutions. By the 1960s, Cleveland's economy began to slow down as manufacturing declined and suburbanization occurred.

The climate is transitional with the Cfa humid subtropical climate. Summers are hot and humid, while winters are cold and snowy. East of the mouth of the Cuyahoga, the land elevation rises rapidly in the south. Together with the prevailing winds off Lake Erie, this feature is the principal contributor to the lake-effect snow that is typical in Cleveland (especially on the city's East Side) from mid-November until the surface of the lake freezes, usually in late January or early February. The lake effect causes a relative differential in geographical snowfall totals across the city. On the city's far West Side, the Hopkins neighborhood only reached 100 inches (254 cm) of snowfall in a season three times since record-keeping for snow began in 1893. By contrast, seasonal totals approaching or exceeding 100 inches (254 cm) are not uncommon as the city ascends into the Heights on the east, where the region known as the 'Snow Belt' begins.

] | Cleveland, officially the City of Cleveland, is a city in the U.S. state of Ohio and the county seat of Cuyahoga County. Located in Northeast Ohio along the southern shore of Lake Erie, it is situated across the U.S. maritime border with Canada and lies approximately 60 miles (97 km) west of Pennsylvania. Cleveland ranks as the largest city on Lake Erie, the second-most populous city in Ohio, and the 54th-most populous city in the U.S. with a 2020 population of 372,624. The city anchors the Cleveland metropolitan area, the 33rd-largest in the U.S. at 2.18 million residents, as well as the larger Cleveland–Akron–Canton combined statistical area, the most populous in Ohio and the 17th-largest in the country with a population of 3.63 million in 2020. Cleveland was founded in 1796 near the mouth of the Cuyahoga River as part of the Connecticut Western Reserve by General Moses Cleaveland, after whom the city was named. Its location on both the river and the lake shore allowed it to grow into a major commercial and industrial metropolis by the late 19th century, attracting large numbers of immigrants and migrants. It was among the top 10 U.S. cities by population for much of the 20th century, a period which saw the development of the city's cultural institutions. By the 1960s, Cleveland's economy began to slow down as manufacturing declined and suburbanization occurred. The city has since developed a diversified economy and gained a national reputation as a center for healthcare and the arts. Cleveland is a port city, connected to the Atlantic Ocean via the Saint Lawrence Seaway. Its economy relies on diverse sectors that include higher education, manufacturing, financial services, healthcare, and biomedicals. The city serves as the headquarters of the Federal Reserve Bank of Cleveland, as well as several major companies. The GDP for the Greater Cleveland MSA was $135 billion in 2019. Combined with the Akron MSA, the eight-county Cleveland–Akron metropolitan economy was $175 billion in 2019, the largest in Ohio, accounting for 25% of the state's GDP. Designated as a global city by the Globalization and World Cities Research Network, Cleveland is home to several major cultural institutions, including the Cleveland Museum of Art, the Cleveland Museum of Natural History, the Cleveland Public Library, the Cleveland Orchestra, Playhouse Square, and the Rock and Roll Hall of Fame, as well as Case Western Reserve University. Known as "The Forest City" among many other nicknames, Cleveland serves as the center of the Cleveland Metroparks nature reserve system. The city's major league professional sports teams include the Cleveland Browns, the Cleveland Cavaliers, and the Cleveland Guardians. | 2001-07-28T01:08:36Z | 2023-12-30T14:35:02Z | [

5,955 | Church of England | The Church of England (C of E) is the established Christian church in England. It traces its history to the Christian church recorded as existing in the Roman province of Britain by the 3rd century and to the 6th-century Gregorian mission to Kent led by Augustine of Canterbury. Its adherents are called Anglicans.
The English church renounced papal authority in 1534 when Henry VIII failed to secure a papal annulment of his marriage to Catherine of Aragon. The English Reformation accelerated under Edward VI's regents, before a brief restoration of papal authority under Queen Mary I and King Philip. The Act of Supremacy 1558 renewed the breach, and the Elizabethan Settlement charted a course enabling the English church to describe itself as both Reformed and Catholic. In the earlier phase of the English Reformation there were both radical Roman Catholic martyrs and radical Protestant martyrs. The later phases saw the Penal Laws punish Roman Catholics and nonconforming Protestants. In the 17th century, the Puritan and Presbyterian factions continued to challenge the leadership of the church, which under the Stuarts veered towards a more Catholic interpretation of the Elizabethan Settlement, especially under Archbishop Laud and the rise of the concept of Anglicanism as a via media between Roman Catholicism and radical Protestantism. After the victory of the Parliamentarians, the Prayer Book was abolished and the Presbyterian and Independent factions dominated. The episcopacy was abolished in 1646 but the Restoration restored the Church of England, episcopacy and the Prayer Book. Papal recognition of George III in 1766 led to greater religious tolerance.
Since the English Reformation, the Church of England has used the English language in the liturgy. As a broad church, the Church of England contains several doctrinal strands. The main traditions are known as Anglo-Catholicism, high churchmanship, central churchmanship and low churchmanship, the latter producing a growing evangelical wing. Tensions between theological conservatives and liberals find expression in debates over the ordination of women and homosexuality. The British monarch (currently Charles III) is the supreme governor and the Archbishop of Canterbury (currently Justin Welby) is the most senior cleric. The governing structure of the church is based on dioceses, each presided over by a bishop. Within each diocese are local parishes. The General Synod of the Church of England is the legislative body for the church and comprises bishops, other clergy and laity. Its measures must be approved by the Parliament of the United Kingdom.
There is evidence for Christianity in Roman Britain as early as the 3rd century. After the fall of the Roman Empire, England was conquered by the Anglo-Saxons, who were pagans, and the Celtic Church was confined to Cornwall and Wales. In 597, Pope Gregory I sent missionaries to England to Christianise the Anglo-Saxons. This mission was led by Augustine, who became the first Archbishop of Canterbury. The Church of England considers 597 the start of its formal history.
In Northumbria, Celtic missionaries competed with their Roman counterparts. The Celtic and Roman churches disagreed over the date of Easter, baptismal customs, and the style of tonsure worn by monks. King Oswiu of Northumbria summoned the Synod of Whitby in 664. The king decided Northumbria would follow the Roman tradition because Saint Peter and his successors, the bishops of Rome, hold the keys of the kingdom of heaven.
By the late Middle Ages, Catholicism was an essential part of English life and culture. The 9,000 parishes covering all of England were overseen by a hierarchy of deaneries, archdeaconries, dioceses led by bishops, and ultimately the pope who presided over the Catholic Church from Rome. Catholicism taught that the contrite person could cooperate with God towards their salvation by performing good works (see synergism). God's grace was given through the seven sacraments. In the Mass, a priest consecrated bread and wine to become the body and blood of Christ through transubstantiation. The Church taught that, in the name of the congregation, the priest offered to God the same sacrifice of Christ on the cross that provided atonement for the sins of humanity. The Mass was also an offering of prayer by which the living could help souls in purgatory. While penance removed the guilt attached to sin, Catholicism taught that a penalty still remained. It was believed that most people would end their lives with these penalties unsatisfied and would have to spend time in purgatory. Time in purgatory could be lessened through indulgences and prayers for the dead, which were made possible by the communion of saints.
In 1527, Henry VIII was desperate for a male heir and asked Pope Clement VII to annul his marriage to Catherine of Aragon. When the pope refused, Henry used Parliament to assert royal authority over the English church. In 1533, Parliament passed the Act in Restraint of Appeals, barring legal cases from being appealed outside England. This allowed the Archbishop of Canterbury to annul the marriage without reference to Rome. In November 1534, the Act of Supremacy formally abolished papal authority and declared Henry Supreme Head of the Church of England.
Henry's religious beliefs remained aligned to traditional Catholicism throughout his reign. In order to secure royal supremacy over the Church, however, Henry allied himself with Protestants, who until that time had been treated as heretics. The main doctrine of the Protestant Reformation was justification by faith alone rather than by good works. The logical outcome of this belief is that the Mass, sacraments, charitable acts, prayers to saints, prayers for the dead, pilgrimage, and the veneration of relics do not mediate divine favour. To believe they can would be superstition at best and idolatry at worst.
Between 1536 and 1540, Henry engaged in the dissolution of the monasteries, which controlled much of the richest land. He disbanded religious houses, appropriated their income, disposed of their assets, and provided pensions for the former residents. The properties were sold to pay for the wars. Historian George W. Bernard argues:
The dissolution of the monasteries in the late 1530s was one of the most revolutionary events in English history. There were nearly 900 religious houses in England, around 260 for monks, 300 for regular canons, 142 nunneries and 183 friaries; some 12,000 people in total, 4,000 monks, 3,000 canons, 3,000 friars and 2,000 nuns....one adult man in fifty was in religious orders.
In the reign of Edward VI (1547–1553), the Church of England underwent an extensive theological reformation. Justification by faith was made a central teaching. Government-sanctioned iconoclasm led to the destruction of images and relics. Stained glass, shrines, statues, and roods were defaced or destroyed. Church walls were whitewashed and covered with biblical texts condemning idolatry. The most significant reform in Edward's reign was the adoption of an English liturgy to replace the old Latin rites. Written by Archbishop Thomas Cranmer, the 1549 Book of Common Prayer implicitly taught justification by faith, and rejected the Catholic doctrines of transubstantiation and the sacrifice of the Mass. This was followed by a greatly revised 1552 Book of Common Prayer that was even more Protestant in tone, going so far as to deny the real presence of Christ in the Eucharist.
During the reign of Mary I (1553–1558), England was briefly reunited with the Catholic Church. Mary died childless, so it was left to the new regime of her half-sister Queen Elizabeth I to resolve the direction of the Church. The Elizabethan Religious Settlement returned the Church to where it stood in 1553 before Edward's death. The Act of Supremacy made the monarch the Church's supreme governor. The Act of Uniformity restored a slightly altered 1552 Book of Common Prayer. In 1571, the Thirty-nine Articles received parliamentary approval as a doctrinal statement for the Church. The settlement ensured the Church of England was Protestant, but it was unclear what kind of Protestantism was being adopted. The prayer book's eucharistic theology was vague. The words of administration neither affirmed nor denied the real presence. Perhaps, a spiritual presence was implied, since Article 28 of the Thirty-nine Articles taught that the body of Christ was eaten "only after an heavenly and spiritual manner". Nevertheless, there was enough ambiguity to allow later theologians to articulate various versions of Anglican eucharistic theology.
The Church of England was the established church (constitutionally established by the state with the head of state as its supreme governor). The exact nature of the relationship between church and state would be a source of continued friction into the next century.
Struggle for control of the church persisted throughout the reigns of James I and his son Charles I, culminating in the outbreak of the First English Civil War in 1642. The two opposing factions consisted of Puritans, who sought to "purify" the church and enact more far-reaching Protestant reforms, and those who wanted to retain traditional beliefs and practices. In a period when many believed "true religion" and "good government" were the same thing, religious disputes often included a political element, one example being the struggle over bishops. In addition to their religious function, bishops acted as state censors, able to ban sermons and writings considered objectionable, while lay people could be tried by church courts for crimes including blasphemy, heresy, fornication and other 'sins of the flesh', as well as matrimonial or inheritance disputes. They also sat in the House of Lords and often blocked legislation opposed by the Crown; their ousting from Parliament by the 1640 Clergy Act was a major step on the road to war.
Following Royalist defeat in 1646, the Episcopacy was formally abolished. In 1649, the Commonwealth of England outlawed a number of former practices and Presbyterian structures replaced the episcopate. The 39 Articles were replaced by the Westminster Confession, the Book of Common Prayer by the Directory of Public Worship. Despite this, about one quarter of English clergy refused to conform to this form of state presbyterianism. It was also opposed by religious Independents who rejected the very idea of state-mandated religion, and included Congregationalists like Oliver Cromwell, as well as Baptists, who were especially well represented in the New Model Army.
After the Stuart Restoration in 1660, Parliament restored the Church of England to a form not far removed from the Elizabethan version. Until James II of England was ousted by the Glorious Revolution in November 1688, many Nonconformists still sought to negotiate terms that would allow them to re-enter the Church. In order to secure his political position, William III of England ended these discussions and the Tudor ideal of encompassing all the people of England in one religious organisation was abandoned. The religious landscape of England assumed its present form, with the Anglican established church occupying the middle ground and Nonconformists continuing their existence outside. One result of the Restoration was the ousting of 2,000 parish ministers who had not been ordained by bishops in the apostolic succession or who had been ordained by ministers in presbyter's orders. Official suspicion and legal restrictions continued well into the 19th century. Roman Catholics, perhaps 5% of the English population (down from 20% in 1600) were grudgingly tolerated, having had little or no official representation after the Pope's excommunication of Queen Elizabeth in 1570, though the Stuarts were sympathetic to them. By the end of 18th century they had dwindled to 1% of the population, mostly amongst upper middle-class gentry, their tenants and extended families.
By the Fifth Article of the Union with Ireland 1800, the Church of England and Church of Ireland were united into "one Protestant Episcopal church, to be called, the United Church of England and Ireland". Although "the continuance and preservation of the said united church ... [was] deemed and taken to be an essential and fundamental part of the union", the Irish Church Act 1869 separated the Irish part of the church again and disestablished it, the Act coming into effect on 1 January 1871.
As the British Empire expanded, British colonists and colonial administrators took the established church doctrines and practices together with ordained ministry and formed overseas branches of the Church of England. As they developed or, beginning with the United States of America, became sovereign or independent states, many of their churches became separate organisationally but remained linked to the Church of England through the Anglican Communion. In the provinces that made up Canada, the church operated as the "Church of England in Canada" until 1955 when it became the Anglican Church of Canada.
In Bermuda, the oldest remaining English colony (now designated a British Overseas Territory), the first Church of England services were performed by the Reverend Richard Buck, one of the survivors of the 1609 wreck of the Sea Venture which initiated Bermuda's permanent settlement. The nine parishes of the Church of England in Bermuda, each with its own church and glebe land, rarely had more than a pair of ordained ministers to share between them until the 19th century. From 1825 to 1839, Bermuda's parishes were attached to the See of Nova Scotia. Bermuda was then grouped into the new Diocese of Newfoundland and Bermuda from 1839. In 1879, the Synod of the Church of England in Bermuda was formed. At the same time, a Diocese of Bermuda became separate from the Diocese of Newfoundland, but both continued to be grouped under the Bishop of Newfoundland and Bermuda until 1919, when Newfoundland and Bermuda each received its own bishop.
The Church of England in Bermuda was renamed in 1978 as the Anglican Church of Bermuda, which is an extra-provincial diocese, with both metropolitan and primatial authority coming directly from the Archbishop of Canterbury. Among its parish churches is St Peter's Church in the UNESCO World Heritage Site of St George's Town, which is the oldest Anglican church outside of the British Isles, and the oldest Protestant church in the New World.
The first Anglican missionaries arrived in Nigeria in 1842 and the first Anglican Nigerian was consecrated a bishop in 1864. However, the arrival of a rival group of Anglican missionaries in 1887 led to infighting that slowed the Church's growth. In this large African colony, by 1900 there were only 35,000 Anglicans, about 0.2% of the population. However, by the late 20th century the Church of Nigeria was the fastest growing of all Anglican churches, reaching about 18 percent of the local population by 2000.
The Church established its presence in Hong Kong and Macau in 1843. In 1951, the Diocese of Hong Kong and Macao became an extra-provincial diocese, and in 1998 it became a province of the Anglican Communion, under the name Hong Kong Sheng Kung Hui.
From 1796 to 1818 the Church began operating in Sri Lanka (formerly Ceylon), following the 1796 start of British colonisation, when the first services were held for the British civil and military personnel. In 1799, the first Colonial Chaplain was appointed, following which CMS and SPG missionaries began their work, in 1818 and 1844 respectively. Subsequently the Church of Ceylon was established: in 1845 the diocese of Colombo was inaugurated, with the appointment of James Chapman as Bishop of Colombo. It served as an extra-provincial jurisdiction of the Archbishop of Canterbury, who served as its Metropolitan.
Under the guidance of Rowan Williams and with significant pressure from clergy union representatives, the ecclesiastical penalty for convicted felons to be defrocked was set aside from the Clergy Discipline Measure 2003. The clergy union argued that the penalty was unfair to victims of hypothetical miscarriages of criminal justice, because the ecclesiastical penalty is considered irreversible. Although clerics can still be banned for life from ministry, they remain ordained as priests.
Bishop Sarah Mullally has insisted that declining numbers at services should not necessarily be a cause of despair for churches, because people may still encounter God without attending a service in a church; for example hearing the Christian message through social media sites or in a café run as a community project. Additionally, 9.7 million people visit at least one of its churches every year and 1 million students are educated at Church of England schools (which number 4,700). In 2019, an estimated 10 million people visited a cathedral and an additional "1.3 million people visited Westminster Abbey, where 99% of visitors paid / donated for entry". Nevertheless, the archbishops of Canterbury and York warned in January 2015 that the Church of England would no longer be able to carry on in its current form unless the downward spiral in membership were somehow to be reversed, as typical Sunday attendance had halved to 800,000 in the previous 40 years:
The urgency of the challenge facing us is not in doubt. Attendance at Church of England services has declined at an average of one per cent per annum over recent decades and, in addition, the age profile of our membership has become significantly older than that of the population... Renewing and reforming aspects of our institutional life is a necessary but far from sufficient response to the challenges facing the Church of England. ... The age profile of our clergy has also been increasing. Around 40 per cent of parish clergy are due to retire over the next decade or so.
Between 1969 and 2010, almost 1,800 church buildings, roughly 11% of the stock, were closed (so-called "redundant churches"); the majority (70%) in the first half of the period; only 514 being closed between 1990 and 2010. Some active use was being made of about half of the closed churches. By 2019 the rate of closure had steadied at around 20 to 25 per year (0.2%); some being replaced by new places of worship. Additionally, in 2018 the church announced a £27 million growth programme to create 100 new churches.
In 2015 the Church of England admitted that it was embarrassed to be paying staff under the living wage. The Church of England had previously campaigned for all employers to pay this minimum amount. The archbishop of Canterbury acknowledged it was not the only area where the church "fell short of its standards".
The COVID-19 pandemic had a sizeable effect on church attendance, with attendance in 2020 and 2021 dropping well below that of 2019. By 2022, the first full year without substantial restrictions related to the pandemic, numbers were still notably down on pre-pandemic participation. According to the 2022 release of "Statistics for Mission" by the church, the median size of each church's "Worshipping Community" (those who attend in person or online at least as regularly as once a month) now stands at 37 people, with average weekly attendance having declined from 34 to 25; while Easter and Christmas services have seen falls from 51 to 38 and 80 to 56 individuals respectively. Examples of wider declines across the whole church include:
The canon law of the Church of England identifies the Christian scriptures as the source of its doctrine. In addition, doctrine is also derived from the teachings of the Church Fathers and ecumenical councils (as well as the ecumenical creeds) in so far as these agree with scripture. This doctrine is expressed in the Thirty-Nine Articles of Religion, the Book of Common Prayer, and the Ordinal containing the rites for the ordination of deacons, priests, and the consecration of bishops. Unlike other traditions, the Church of England has no single theologian that it can look to as a founder. However, Richard Hooker's appeal to scripture, church tradition, and reason as sources of authority, as well as the work of Thomas Cranmer, which inspired the doctrinal status of the church, continue to inform Anglican identity.
The Church of England's doctrinal character today is largely the result of the Elizabethan Settlement, which sought to establish a comprehensive middle way between Roman Catholicism and Protestantism. The Church of England affirms the protestant reformation principle that scripture contains all things necessary to salvation and is the final arbiter in doctrinal matters. The Thirty-nine Articles are the church's only official confessional statement. Though not a complete system of doctrine, the articles highlight areas of agreement with Lutheran and Reformed positions, while differentiating Anglicanism from Roman Catholicism and Anabaptism.
While embracing some themes of the Protestant Reformation, the Church of England also maintains Catholic traditions of the ancient church and teachings of the Church Fathers, unless these are considered contrary to scripture. It accepts the decisions of the first four ecumenical councils concerning the Trinity and the Incarnation. The Church of England also preserves catholic order by adhering to episcopal polity, with ordained orders of bishops, priests and deacons. There are differences of opinion within the Church of England over the necessity of episcopacy. Some consider it essential, while others feel it is needed for the proper ordering of the church. In sum these express the 'Via Media' viewpoint that the first five centuries of doctrinal development and church order as approved are acceptable as a yardstick by which to gauge authentic catholicity, as minimum and sufficient; Anglicanism did not emerge as the result of charismatic leaders with particular doctrines. It is light on details compared to Roman Catholic, Reformed and Lutheran teachings. The Bible, the Creeds, Apostolic Order, and the administration of the Sacraments are sufficient to establish catholicity. The Reformation in England was initially much concerned about doctrine but the Elizabethan Settlement tried to put a stop to doctrinal contentions. The proponents of further changes, nonetheless, tried to get their way by making changes in Church Order (abolition of bishops), governance (Canon Law) and liturgy ('too Catholic'). They did not succeed because the monarchy and the Church resisted and the majority of the population were indifferent. Moreover, "despite all the assumptions of the Reformation founders of that Church, it had retained a catholic character." The Elizabethan Settlement had created a cuckoo in a nest..." a Protestant theology and program within a largely pre-Reformation Catholic structure whose continuing life would arouse a theological interest in the Catholicism that had created it; and would result in the rejection of predestinarian theology in favor of sacraments, especially the eucharist, ceremonial, and anti-Calvinist doctrine". The existence of cathedrals "without substantial alteration" and "where the "old devotional world cast its longest shadow for the future of the ethos that would become Anglicanism," This is "One of the great mysteries of the English Reformation," that there was no complete break with the past but a muddle that was per force turned into a virtue. The story of the English Reformation is the tale of retreat from the Protestant advance of 1550 which could not proceed further in the face of the opposition of the institution which was rooted in the medieval past, and the adamant opposition of Queen Elizabeth I.
The Church of England has, as one of its distinguishing marks, a breadth of opinion from liberal to conservative clergy and members. This tolerance has allowed Anglicans who emphasise the catholic tradition and others who emphasise the reformed tradition to coexist. The three schools of thought (or parties) in the Church of England are sometimes called high church (or Anglo-Catholic), low church (or evangelical Anglican) and broad church (or liberal). The high church party places importance on the Church of England's continuity with the pre-Reformation Catholic Church, adherence to ancient liturgical usages and the sacerdotal nature of the priesthood. As their name suggests, Anglo-Catholics maintain many traditional catholic practices and liturgical forms. The Catholic tradition, strengthened and reshaped from the 1830s by the Oxford movement, has stressed the importance of the visible Church and its sacraments and the belief that the ministry of bishops, priests and deacons is a sign and instrument of the Church of England's Catholic and apostolic identity. The low church party is more Protestant in both ceremony and theology. It has emphasized the significance of the Protestant aspects of the Church of England's identity, stressing the importance of the authority of Scripture, preaching, justification by faith and personal conversion. Historically, the term 'broad church' has been used to describe those of middle-of-the-road ceremonial preferences who lean theologically towards liberal protestantism. The liberal broad church tradition has emphasized the importance of the use of reason in theological exploration. It has stressed the need to develop Christian belief and practice in order to respond creatively to wider advances in human knowledge and understanding and the importance of social and political action in forwarding God's kingdom. The balance between these strands of churchmanship is not static: in 2013, 40% of Church of England worshippers attended evangelical churches (compared with 26% in 1989), and 83% of very large congregations were evangelical. Such churches were also reported to attract higher numbers of men and young adults than others.
In 1604, James I ordered an English language translation of the Bible known as the King James Version, which was published in 1611 and authorised for use in parishes, although it was not an "official" version per se. The Church of England's official book of liturgy as established in English Law is the 1662 version of the Book of Common Prayer (BCP). In the year 2000, the General Synod approved a modern liturgical book, Common Worship, which can be used as an alternative to the BCP. Like its predecessor, the 1980 Alternative Service Book, it differs from the Book of Common Prayer in providing a range of alternative services, mostly in modern language, although it does include some BCP-based forms as well, for example Order Two for Holy Communion. (This is a revision of the BCP service, altering some words and allowing the insertion of some other liturgical texts such as the Agnus Dei before communion.) The Order One rite follows the pattern of more modern liturgical scholarship.
The liturgies are organised according to the traditional liturgical year and the calendar of saints. The sacraments of baptism and the eucharist are generally thought necessary to salvation. Infant baptism is practised. At a later age, individuals baptised as infants receive confirmation by a bishop, at which time they reaffirm the baptismal promises made by their parents or sponsors. The eucharist, consecrated by a thanksgiving prayer including Christ's Words of Institution, is believed to be "a memorial of Christ's once-for-all redemptive acts in which Christ is objectively present and effectually received in faith".
The use of hymns and music in the Church of England has changed dramatically over the centuries. Traditional Choral evensong is a staple of most cathedrals. The style of psalm chanting harks back to the Church of England's pre-reformation roots. During the 18th century, clergy such as Charles Wesley introduced their own styles of worship with poetic hymns.
In the latter half of the 20th century, the influence of the Charismatic Movement significantly altered the worship traditions of numerous Church of England parishes, primarily affecting those of evangelical persuasion. These churches now adopt a contemporary worship form of service, with minimal liturgical or ritual elements, and incorporating contemporary worship music.
Just as the Church of England has a large conservative or "traditionalist" wing, it also has many liberal members and clergy. Approximately one third of clergy "doubt or disbelieve in the physical resurrection". Others, such as Giles Fraser, a contributor to The Guardian, have argued for an allegorical interpretation of the virgin birth of Jesus. The Independent reported in 2014 that, according to a YouGov survey of Church of England clergy, "as many as 16 per cent are unclear about God and two per cent think it is no more than a human construct." Moreover, many congregations are seeker-friendly environments. For example, one report from the Church Mission Society suggested that the church open up "a pagan church where Christianity [is] very much in the centre" to reach out to spiritual people.
The Church of England is launching a project on "gendered language" in Spring 2023 in efforts to "study the ways in which God is referred to and addressed in liturgy and worship".
Women were appointed as deaconesses from 1861, but they could not function fully as deacons and were not considered ordained clergy. Women have historically been able to serve as lay readers. During the First World War, some women were appointed as lay readers, known as "bishop's messengers", who also led missions and ran churches in the absence of men. After the war, no women were appointed as lay readers until 1969.
Legislation authorising the ordination of women as deacons was passed in 1986 and they were first ordained in 1987. The ordination of women as priests was approved by the General Synod in 1992 and began in 1994. In 2010, for the first time in the history of the Church of England, more women than men were ordained as priests (290 women and 273 men), but in the next two years, ordinations of men again exceeded those of women.
In July 2005, the synod voted to "set in train" the process of allowing the consecration of women as bishops. In February 2006, the synod voted overwhelmingly for the "further exploration" of possible arrangements for parishes that did not want to be directly under the authority of a bishop who is a woman. On 7 July 2008, the synod voted to approve the ordination of women as bishops and rejected moves for alternative episcopal oversight for those who do not accept the ministry of bishops who are women. Actual ordinations of women to the episcopate required further legislation, which was narrowly rejected in a General Synod vote in November 2012. On 20 November 2013, the General Synod voted overwhelmingly in support of a plan to allow the ordination of women as bishops, with 378 in favour, 8 against and 25 abstentions.
On 14 July 2014, the General Synod approved the ordination of women as bishops. The House of Bishops recorded 37 votes in favour, two against with one abstention. The House of Clergy had 162 in favour, 25 against and four abstentions. The House of Laity voted 152 for, 45 against with five abstentions. This legislation had to be approved by the Ecclesiastical Committee of the Parliament before it could be finally implemented at the November 2014 synod. In December 2014, Libby Lane was announced as the first woman to become a bishop in the Church of England. She was consecrated as a bishop in January 2015. In July 2015, Rachel Treweek was the first woman to become a diocesan bishop in the Church of England when she became the Bishop of Gloucester. She and Sarah Mullally, Bishop of Crediton, were the first women to be ordained as bishops at Canterbury Cathedral. Treweek later made headlines by calling for gender-inclusive language, saying that "God is not to be seen as male. God is God."
In May 2018, the Diocese of London consecrated Dame Sarah Mullally as the first woman to serve as the Bishop of London. Bishop Sarah Mullally occupies the third most senior position in the Church of England. Mullally has described herself as a feminist and will ordain both men and women to the priesthood. She is also considered by some to be a theological liberal. On women's reproductive rights, Mullally describes herself as pro-choice while also being personally pro-life. On marriage, she supports the current stance of the Church of England that marriage is between a man and a woman, but also said that: "It is a time for us to reflect on our tradition and scripture, and together say how we can offer a response that is about it being inclusive love."
The Church of England has been discussing same-sex marriages and LGBT clergy. The church holds that marriage is a union of one man with one woman. The church does not allow clergy to perform same-sex marriages, but in February 2023 approved of blessings for same-sex couples following a civil marriage or civil partnership. The church teaches "Same-sex relationships often embody genuine mutuality and fidelity." In January 2023, the Bishops approved "prayers of thanksgiving, dedication and for God's blessing for same-sex couples." The commended prayers of blessing for same-sex couples, known as "Prayers of Love and Faith," may be used during ordinary church services, and in November 2023 General Synod voted to authorise "standalone" blessings for same-sex couples on a trial basis, while permanent authorisation will require additional steps. The church also officially supports celibate civil partnerships; "We believe that Civil Partnerships still have a place, including for some Christian LGBTI couples who see them as a way of gaining legal recognition of their relationship."
Civil partnerships for clergy have been allowed since 2005, so long as they remain sexually abstinent, and the church extends pensions to clergy in same-sex civil partnerships. In a missive to clergy, the church communicated that "there was a need for committed same-sex couples to be given recognition and 'compassionate attention' from the Church, including special prayers." "There is no prohibition on prayers being said in church or there being a 'service'" after a civil union. After same-sex marriage was legalised, the church sought continued availability of civil unions, saying "The Church of England recognises that same-sex relationships often embody fidelity and mutuality. Civil partnerships enable these Christian virtues to be recognised socially and legally in a proper framework."
In 2014, the bishops released guidelines that permit "more informal kind of prayer" for couples. In the guidelines, "gay couples who get married will be able to ask for special prayers in the Church of England after their wedding, the bishops have agreed." In 2016, the bishop of Grantham, Nicholas Chamberlain, announced that he is gay, in a same-sex relationship and celibate, becoming the first bishop to do so in the church. The church had decided in 2013 that gay clergy in civil partnerships so long as they remain sexually abstinent could become bishops. "The House [of Bishops] has confirmed that clergy in civil partnerships, and living in accordance with the teaching of the church on human sexuality, can be considered as candidates for the episcopate."
In 2017, the House of Clergy voted against the motion to "take note" of the bishops' report defining marriage as between a man and a woman. Due to passage in all three houses being required, the motion was rejected. After General Synod rejected the motion, the archbishops of Canterbury and York called for "radical new Christian inclusion" that is "based on good, healthy, flourishing relationships, and in a proper 21st century understanding of being human and of being sexual." The church officially opposes "conversion therapy", a practice which attempts to change a gay or lesbian person's sexual orientation, calling it unethical and supports the banning of "conversion therapy" in the UK. The Diocese of Hereford approved a motion calling for the church "to create a set of formal services and prayers to bless those who have had a same-sex marriage or civil partnership." In 2022, "The House [of Bishops] also agreed to the formation of a Pastoral Consultative Group to support and advise dioceses on pastoral responses to circumstances that arise concerning LGBTI+ clergy, ordinands, lay leaders and the lay people in their care."
Regarding transgender issues, the 2017 General Synod voted in favour of a motion saying that transgender people should be "welcomed and affirmed in their parish church". The motion also asked the bishops "to look into special services for transgender people." The bishops initially said "the House notes that the Affirmation of Baptismal Faith, found in Common Worship, is an ideal liturgical rite which trans people can use to mark this moment of personal renewal." The Bishops also authorised services of celebration to mark a gender transition that will be included in formal liturgy. Transgender people may marry in the Church of England after legally making a transition. "Since the Gender Recognition Act 2004, trans people legally confirmed in their gender identity under its provisions are able to marry someone of the opposite sex in their parish church." The church further decided that same-gender couples may remain married when one spouse experiences gender transition provided that the spouses identified as opposite genders at the time of the marriage. Since 2000, the church has allowed priests to undergo gender transition and remain in office. The church has ordained openly transgender clergy since 2005. The Church of England ordained the church's first openly non-binary priest.
In January 2023, a meeting of the Bishops of the Church of England rejected demands for clergy to conduct same-sex marriages. However, proposals would be put to the General Synod that clergy should be able to hold church blessings for same-sex civil marriages, albeit on a voluntary basis for individual clergy. This comes as the Church continued to be split on same-sex marriages.
In February 2023, ten archbishops of the Global South Fellowship of Anglican Churches released a statement stating that they had broken communion and no longer recognised Justin Welby as "the first among equals" or "primus inter pares" in the Anglican Communion in response to the General Synod's decision to approve the blessing of same-sex couples following a civil marriage or partnership, leading to questions as to the status of the Church of England as the mother church of the international Anglican Communion.
In November 2023, the General Synod narrowly voted to allow church blessings for same-sex couples on a trial basis. In December 2023, the first blessings of same-sex couples began in the Church of England.
The Church of England is generally opposed to abortion but believes "there can be strictly limited conditions under which abortion may be morally preferable to any available alternative". The church also opposes euthanasia. Its official stance is that "While acknowledging the complexity of the issues involved in assisted dying/suicide and voluntary euthanasia, the Church of England is opposed to any change in the law or in medical practice that would make assisted dying/suicide or voluntary euthanasia permissible in law or acceptable in practice." It also states that "Equally, the Church shares the desire to alleviate physical and psychological suffering, but believes that assisted dying/suicide and voluntary euthanasia are not acceptable means of achieving these laudable goals." In 2014, George Carey, a former archbishop of Canterbury, announced that he had changed his stance on euthanasia and now advocated legalising "assisted dying". On embryonic stem-cell research, the church has announced "cautious acceptance to the proposal to produce cytoplasmic hybrid embryos for research".
In the 19th century, English law required the burial of people who had died by suicide to occur only between the hours of 9 p.m. and midnight and without religious rites. The Church of England permitted the use of alternative burial services for people who had died by suicide. In 2017, the Church of England changed its rules to permit the full, standard Christian burial service regardless of whether a person had died by suicide.
The Church of England set up the Church Urban Fund in the 1980s to tackle poverty and deprivation. It sees poverty as trapping individuals and communities with some people in urgent need, leading to dependency, homelessness, hunger, isolation, low income, mental health problems, social exclusion and violence. They feel that poverty reduces confidence and life expectancy and that people born in poor conditions have difficulty escaping their disadvantaged circumstances.
In parts of Liverpool, Manchester and Newcastle two-thirds of babies are born to poverty and have poorer life chances, also a life expectancy 15 years lower than babies born in the best-off fortunate communities.
The deep-rooted unfairness in our society is highlighted by these stark statistics. Children being born in this country, just a few miles apart, couldn't witness a more wildly differing start to life. In child poverty terms, we live in one of the most unequal countries in the western world. We want people to understand where their own community sits alongside neighbouring communities. The disparity is often shocking but it's crucial that, through greater awareness, people from all backgrounds come together to think about what could be done to support those born into poverty. [Paul Hackwood, the Chair of Trustees at Church Urban Fund]
Many prominent people in the Church of England have spoken out against poverty and welfare cuts in the United Kingdom. Twenty-seven bishops are among 43 Christian leaders who signed a letter which urged David Cameron to make sure people have enough to eat.
We often hear talk of hard choices. Surely few can be harder than that faced by the tens of thousands of older people who must 'heat or eat' each winter, harder than those faced by families whose wages have stayed flat while food prices have gone up 30% in just five years. Yet beyond even this we must, as a society, face up to the fact that over half of people using food banks have been put in that situation by cutbacks to and failures in the benefit system, whether it be payment delays or punitive sanctions.
Thousands of UK citizens use food banks. The church's campaign to end hunger considers this "truly shocking" and called for a national day of fasting on 4 April 2014.
As of 2009, the Church of England estimated that it had approximately 26 million baptised members – about 47% of the English population. This number has remained consistent since 2001 and was cited again in 2013 and 2014. According to a 2016 study published by the Journal of Anglican Studies, the Church of England continued to claim 26 million baptised members, while it also had approximately 1.7 million active baptised members. Due to its status as the established church, in general, anyone may be married, have their children baptised or their funeral in their local parish church, regardless of whether they are baptised or regular churchgoers.
Between 1890 and 2001, churchgoing in the United Kingdom declined steadily. In the years 1968 to 1999, Anglican Sunday church attendances almost halved, from 3.5 percent of the population to 1.9 per cent. By 2014, Sunday church attendances had declined further to 1.4 per cent of the population. One study published in 2008 suggested that if current trends continued, Sunday attendances could fall to 350,000 in 2030 and 87,800 in 2050. The Church of England releases an annual publication, Statistics for Mission, detailing numerous criteria relating to participation with the church. Below is a snapshot of several key metrics from every five years since 2001 (2022 has been used in place of 2021 to avoid the impact of covid restrictions).
In 2020, there were almost 20,000 active clergy serving in the Church of England, including 7,200 retired clergy who continued to serve. In that year, 580 were ordained (330 in stipendiary posts and 250 in self-supporting parochial posts) and a further 580 ordinands began their training. In that year, 33% of those in ordained ministry were female, an increase from the 26% reported in 2016.
Article XIX ('Of the Church') of the 39 Articles defines the church as follows:
The visible Church of Christ is a congregation of faithful men, in which the pure Word of God is preached, and the sacraments be duly ministered according to Christ's ordinance in all those things that of necessity are requisite to the same.
The British monarch has the constitutional title of Supreme Governor of the Church of England. The canon law of the Church of England states, "We acknowledge that the King's most excellent Majesty, acting according to the laws of the realm, is the highest power under God in this kingdom, and has supreme authority over all persons in all causes, as well ecclesiastical as civil." In practice this power is often exercised through Parliament and on the advice of the Prime Minister.
The Church of Ireland and the Church in Wales separated from the Church of England in 1869 and 1920 respectively and are autonomous churches in the Anglican Communion; Scotland's national church, the Church of Scotland, is Presbyterian, but the Scottish Episcopal Church is part of the Anglican Communion.
In addition to England, the jurisdiction of the Church of England extends to the Isle of Man, the Channel Islands and a few parishes in Flintshire, Monmouthshire and Powys in Wales which voted to remain with the Church of England rather than joining the Church in Wales. Expatriate congregations on the continent of Europe have become the Diocese of Gibraltar in Europe.
The church is structured as follows (from the lowest level upwards):
All rectors and vicars are appointed by patrons, who may be private individuals, corporate bodies such as cathedrals, colleges or trusts, or by the bishop or directly by the Crown. No clergy can be instituted and inducted into a parish without swearing the Oath of Allegiance to His Majesty, and taking the Oath of Canonical Obedience "in all things lawful and honest" to the bishop. Usually they are instituted to the benefice by the bishop and then inducted by the archdeacon into the possession of the benefice property—church and parsonage. Curates (assistant clergy) are appointed by rectors and vicars, or if priests-in-charge by the bishop after consultation with the patron. Cathedral clergy (normally a dean and a varying number of residentiary canons who constitute the cathedral chapter) are appointed either by the Crown, the bishop, or by the dean and chapter themselves. Clergy officiate in a diocese either because they hold office as beneficed clergy or are licensed by the bishop when appointed, or simply with permission.
The most senior bishop of the Church of England is the Archbishop of Canterbury, who is the metropolitan of the southern province of England, the Province of Canterbury. He has the status of Primate of All England. He is the focus of unity for the worldwide Anglican Communion of independent national or regional churches. Justin Welby has been Archbishop of Canterbury since the confirmation of his election on 4 February 2013.
The second most senior bishop is the Archbishop of York, who is the metropolitan of the northern province of England, the Province of York. For historical reasons (relating to the time of York's control by the Danes) he is referred to as the Primate of England. Stephen Cottrell became Archbishop of York in 2020. The Bishop of London, the Bishop of Durham and the Bishop of Winchester are ranked in the next three positions, insofar as the holders of those sees automatically become members of the House of Lords.
The process of appointing diocesan bishops is complex, due to historical reasons balancing hierarchy against democracy, and is handled by the Crown Nominations Committee which submits names to the Prime Minister (acting on behalf of the Crown) for consideration.
The Church of England has a legislative body, General Synod. This can create two types of legislation, measures and canons. Measures have to be approved but cannot be amended by the British Parliament before receiving the Royal Assent and becoming part of the law of England. Although it is the established church in England only, its measures must be approved by both Houses of Parliament including the non-English members. Canons require Royal Licence and Royal Assent, but form the law of the church, rather than the law of the land.
Another assembly is the Convocation of the English Clergy, which is older than the General Synod and its predecessor the Church Assembly. By the 1969 Synodical Government Measure almost all of the Convocations' functions were transferred to the General Synod. Additionally, there are Diocesan Synods and deanery synods, which are the governing bodies of the divisions of the Church.
Of the 42 diocesan archbishops and bishops in the Church of England, 26 are permitted to sit in the House of Lords. The Archbishops of Canterbury and York automatically have seats, as do the bishops of London, Durham and Winchester. The remaining 21 seats are filled in order of seniority by date of consecration. It may take a diocesan bishop a number of years to reach the House of Lords, at which point he or she becomes a Lord Spiritual. The Bishop of Sodor and Man and the Bishop of Gibraltar in Europe are not eligible to sit in the House of Lords as their dioceses lie outside the United Kingdom.
Although they are not part of England or the United Kingdom, the Church of England is also the established church in the Crown Dependencies of the Isle of Man, the Bailiwick of Jersey and the Bailiwick of Guernsey. The Isle of Man has its own diocese of Sodor and Man, and the Bishop of Sodor and Man is an ex officio member of the legislative council of the Tynwald on the island. Historically the Channel Islands have been under the authority of the Bishop of Winchester, but this authority has temporarily been delegated to the Bishop of Dover since 2015. In Jersey the Dean of Jersey is a non-voting member of the States of Jersey. In Guernsey the Church of England is the established church, although the Dean of Guernsey is not a member of the States of Guernsey.
The 2020 report from the Independent Inquiry into Child Sexual Abuse found several cases of sexual abuse within the Church of England, and concluded that the Church did not protect children from sexual abuse, and allowed abusers to hide. The Church spent more effort defending alleged abusers than supporting victims or protecting children and young people. Allegations were not taken seriously, and in some cases clergymen were ordained even with a history of child sex abuse. Bishop Peter Ball was convicted in October 2015 on several charges of indecent assault against young adult men.
In June 2023, the Archbishops' Council dismissed the three board members of the Independent Safeguarding Board, which was set up in 2021 "to hold the Church to account, publicly if needs be, for any failings which are preventing good safeguarding from happening". A statement issued by the Archbishops of Canterbury and York referred to there being "no prospect of resolving the disagreement and that it is getting in the way of the vital work of serving victims and survivors". Jasvinder Sanghera and Steve Reeves, the two independent members of the board, had complained about interference with their work by the Church. The Bishop of Birkenhead, Julie Conalty, speaking to BBC Radio 4 in connection with the dismissals, said: "I think culturally we are resistant as a church to accountability, to criticism. And therefore I don't entirely trust the church, even though I'm a key part of it and a leader within it, because I see the way the wind blows is always in a particular direction."
On 20 July 2023, it was announced that the archbishops of Canterbury and York had appointed Alexis Jay to provide proposals for an independent system of safeguarding for the Church of England.
Although an established church, the Church of England does not receive any direct government support, except some funding for building work. Donations comprise its largest source of income, and it also relies heavily on the income from its various historic endowments. In 2005, the Church of England had estimated total outgoings of around £900 million.
The Church of England manages an investment portfolio which is worth more than £8 billion.
The Church of England runs A Church Near You, an online directory of churches. A user-edited resource, it currently lists more than 16,000 churches and has 20,000 editors in 42 dioceses. The directory enables parishes to maintain accurate location, contact and event information, which is shared with other websites and mobile apps. The site allows the public to find their local worshipping community, and offers churches free resources, such as hymns, videos and social media graphics.
The Church Heritage Record includes information on over 16,000 church buildings, including architectural history, archaeology, art history, and the surrounding natural environment. It can be searched by elements including church name, diocese, date of construction, footprint size, listing grade, and church type. The types of church identified include: | [

In the earlier phase of the English Reformation there were both radical Roman Catholic martyrs and radical Protestant martyrs. The later phases saw the Penal Laws punish Roman Catholics and nonconforming Protestants. In the 17th century, the Puritan and Presbyterian factions continued to challenge the leadership of the church, which under the Stuarts veered towards a more Catholic interpretation of the Elizabethan Settlement, especially under Archbishop Laud and the rise of the concept of Anglicanism as a via media between Roman Catholicism and radical Protestantism. After the victory of the Parliamentarians, the Prayer Book was abolished and the Presbyterian and Independent factions dominated.

Tensions between theological conservatives and liberals find expression in debates over the ordination of women and homosexuality.

The 9,000 parishes covering all of England were overseen by a hierarchy of deaneries, archdeaconries, dioceses led by bishops, and ultimately the pope who presided over the Catholic Church from Rome. Catholicism taught that the contrite person could cooperate with God towards their salvation by performing good works (see synergism). God's grace was given through the seven sacraments. In the Mass, a priest consecrated bread and wine to become the body and blood of Christ through transubstantiation. The Church taught that, in the name of the congregation, the priest offered to God the same sacrifice of Christ on the cross that provided atonement for the sins of humanity. The Mass was also an offering of prayer by which the living could help souls in purgatory. While penance removed the guilt attached to sin, Catholicism taught that a penalty still remained. It was believed that most people would end their lives with these penalties unsatisfied and would have to spend time in purgatory. Time in purgatory could be lessened through indulgences and prayers for the dead, which were made possible by the communion of saints.",

Church walls were whitewashed and covered with biblical texts condemning idolatry. The most significant reform in Edward's reign was the adoption of an English liturgy to replace the old Latin rites. Written by Archbishop Thomas Cranmer, the 1549 Book of Common Prayer implicitly taught justification by faith, and rejected the Catholic doctrines of transubstantiation and the sacrifice of the Mass. This was followed by a greatly revised 1552 Book of Common Prayer that was even more Protestant in tone, going so far as to deny the real presence of Christ in the Eucharist.",

The Act of Uniformity restored a slightly altered 1552 Book of Common Prayer. In 1571, the Thirty-nine Articles received parliamentary approval as a doctrinal statement for the Church. The settlement ensured the Church of England was Protestant, but it was unclear what kind of Protestantism was being adopted. The prayer book's eucharistic theology was vague. The words of administration neither affirmed nor denied the real presence. Perhaps, a spiritual presence was implied, since Article 28 of the Thirty-nine Articles taught that the body of Christ was eaten \"only after an heavenly and spiritual manner\".

In a period when many believed \"true religion\" and \"good government\" were the same thing, religious disputes often included a political element, one example being the struggle over bishops. In addition to their religious function, bishops acted as state censors, able to ban sermons and writings considered objectionable, while lay people could be tried by church courts for crimes including blasphemy, heresy, fornication and other 'sins of the flesh', as well as matrimonial or inheritance disputes.

Until James II of England was ousted by the Glorious Revolution in November 1688, many Nonconformists still sought to negotiate terms that would allow them to re-enter the Church. In order to secure his political position, William III of England ended these discussions and the Tudor ideal of encompassing all the people of England in one religious organisation was abandoned. The religious landscape of England assumed its present form, with the Anglican established church occupying the middle ground and Nonconformists continuing their existence outside. One result of the Restoration was the ousting of 2,000 parish ministers who had not been ordained by bishops in the apostolic succession or who had been ordained by ministers in presbyter's orders. Official suspicion and legal restrictions continued well into the 19th century. Roman Catholics, perhaps 5% of the English population (down from 20% in 1600) were grudgingly tolerated, having had little or no official representation after the Pope's excommunication of Queen Elizabeth in 1570, though the Stuarts were sympathetic to them. By the end of 18th century they had dwindled to 1% of the population, mostly amongst upper middle-class gentry, their tenants and extended families.",

The Church of England also preserves catholic order by adhering to episcopal polity, with ordained orders of bishops, priests and deacons. There are differences of opinion within the Church of England over the necessity of episcopacy. Some consider it essential, while others feel it is needed for the proper ordering of the church. In sum these express the 'Via Media' viewpoint that the first five centuries of doctrinal development and church order as approved are acceptable as a yardstick by which to gauge authentic catholicity, as minimum and sufficient; Anglicanism did not emerge as the result of charismatic leaders with particular doctrines. It is light on details compared to Roman Catholic, Reformed and Lutheran teachings. The Bible, the Creeds, Apostolic Order, and the administration of the Sacraments are sufficient to establish catholicity. The Reformation in England was initially much concerned about doctrine but the Elizabethan Settlement tried to put a stop to doctrinal contentions. The proponents of further changes, nonetheless, tried to get their way by making changes in Church Order (abolition of bishops), governance (Canon Law) and liturgy ('too Catholic'). They did not succeed because the monarchy and the Church resisted and the majority of the population were indifferent. Moreover, \"despite all the assumptions of the Reformation founders of that Church, it had retained a catholic character.\" The Elizabethan Settlement had created a cuckoo in a nest...\" a Protestant theology and program within a largely pre-Reformation Catholic structure whose continuing life would arouse a theological interest in the Catholicism that had created it; and would result in the rejection of predestinarian theology in favor of sacraments, especially the eucharist, ceremonial, and anti-Calvinist doctrine\". The existence of cathedrals \"without substantial alteration\" and \"where the \"old devotional world cast its longest shadow for the future of the ethos that would become Anglicanism,\" This is \"One of the great mysteries of the English Reformation,\" that there was no complete break with the past but a muddle that was per force turned into a virtue. The story of the English Reformation is the tale of retreat from the Protestant advance of 1550 which could not proceed further in the face of the opposition of the institution which was rooted in the medieval past, and the adamant opposition of Queen Elizabeth I.",

"text": "The Church of England has, as one of its distinguishing marks, a breadth of opinion from liberal to conservative clergy and members. This tolerance has allowed Anglicans who emphasise the catholic tradition and others who emphasise the reformed tradition to coexist. The three schools of thought (or parties) in the Church of England are sometimes called high church (or Anglo-Catholic), low church (or evangelical Anglican) and broad church (or liberal). The high church party places importance on the Church of England's continuity with the pre-Reformation Catholic Church, adherence to ancient liturgical usages and the sacerdotal nature of the priesthood. As their name suggests, Anglo-Catholics maintain many traditional catholic practices and liturgical forms. The Catholic tradition, strengthened and reshaped from the 1830s by the Oxford movement, has stressed the importance of the visible Church and its sacraments and the belief that the ministry of bishops, priests and deacons is a sign and instrument of the Church of England's Catholic and apostolic identity. The low church party is more Protestant in both ceremony and theology. It has emphasized the significance of the Protestant aspects of the Church of England's identity, stressing the importance of the authority of Scripture, preaching, justification by faith and personal conversion. Historically, the term 'broad church' has been used to describe those of middle-of-the-road ceremonial preferences who lean theologically towards liberal protestantism. The liberal broad church tradition has emphasized the importance of the use of reason in theological exploration. It has stressed the need to develop Christian belief and practice in order to respond creatively to wider advances in human knowledge and understanding and the importance of social and political action in forwarding God's kingdom. The balance between these strands of churchmanship is not static: in 2013, 40% of Church of England worshippers attended evangelical churches (compared with 26% in 1989), and 83% of very large congregations were evangelical.

] | The Church of England is the established Christian church in England. It traces its history to the Christian church recorded as existing in the Roman province of Britain by the 3rd century and to the 6th-century Gregorian mission to Kent led by Augustine of Canterbury. Its adherents are called Anglicans. The English church renounced papal authority in 1534 when Henry VIII failed to secure a papal annulment of his marriage to Catherine of Aragon. The English Reformation accelerated under Edward VI's regents, before a brief restoration of papal authority under Queen Mary I and King Philip. The Act of Supremacy 1558 renewed the breach, and the Elizabethan Settlement charted a course enabling the English church to describe itself as both Reformed and Catholic. In the earlier phase of the English Reformation there were both radical Roman Catholic martyrs and radical Protestant martyrs. The later phases saw the Penal Laws punish Roman Catholics and nonconforming Protestants. In the 17th century, the Puritan and Presbyterian factions continued to challenge the leadership of the church, which under the Stuarts veered towards a more Catholic interpretation of the Elizabethan Settlement, especially under Archbishop Laud and the rise of the concept of Anglicanism as a via media between Roman Catholicism and radical Protestantism. After the victory of the Parliamentarians, the Prayer Book was abolished and the Presbyterian and Independent factions dominated. The episcopacy was abolished in 1646 but the Restoration restored the Church of England, episcopacy and the Prayer Book. Papal recognition of George III in 1766 led to greater religious tolerance. Since the English Reformation, the Church of England has used the English language in the liturgy. As a broad church, the Church of England contains several doctrinal strands. The main traditions are known as Anglo-Catholicism, high churchmanship, central churchmanship and low churchmanship, the latter producing a growing evangelical wing. Tensions between theological conservatives and liberals find expression in debates over the ordination of women and homosexuality. The British monarch is the supreme governor and the Archbishop of Canterbury is the most senior cleric. The governing structure of the church is based on dioceses, each presided over by a bishop. Within each diocese are local parishes. The General Synod of the Church of England is the legislative body for the church and comprises bishops, other clergy and laity. Its measures must be approved by the Parliament of the United Kingdom. | 2001-09-01T23:32:26Z | 2023-12-29T15:27:15Z | [

5,956 | Circe | Circe (/ˈsɜːrsiː/; Ancient Greek: Κίρκη : Kírkē, pronounced [kírkɛː]) is an enchantress and a minor goddess in ancient Greek mythology and religion. In most accounts, Circe is described as the daughter of the sun god Helios and the Oceanid nymph Perse. Circe was renowned for her vast knowledge of potions and herbs. Through the use of these and a magic wand or staff, she would transform her enemies, or those who offended her, into animals.
The best known of her legends is told in Homer's Odyssey when Odysseus visits her island of Aeaea on the way back from the Trojan War and she changes most of his crew into swine. He manages to persuade her to return them to human shape, lives with her for a year and has sons by her, including Latinus and Telegonus. Her ability to change others into animals is further highlighted by the story of Picus, an Italian king whom she turns into a woodpecker for resisting her advances. Another story tells of her falling in love with the sea-god Glaucus, who prefers the nymph Scylla to her. In revenge, Circe poisoned the water where her rival bathed and turned her into a dreadful monster.
Depictions, even in Classical times, diverged from the detail in Homer's narrative, which was later to be reinterpreted morally as a cautionary story against drunkenness. Early philosophical questions were also raised about whether the change from being a human endowed with reason to being an unreasoning beast might not be preferable after all, and the resulting debate was to have a powerful impact during the Renaissance. Circe was also taken as the archetype of the predatory female. In the eyes of those from a later age, this behaviour made her notorious both as a magician and as a type of sexually free woman. She has been frequently depicted as such in all the arts from the Renaissance down to modern times.
Western paintings established a visual iconography for the figure, but also went for inspiration to other stories concerning Circe that appear in Ovid's Metamorphoses. The episodes of Scylla and Picus added the vice of violent jealousy to her bad qualities and made her a figure of fear as well as of desire.
By most accounts, she was the daughter of the sun god Helios and Perse, one of the three thousand Oceanid nymphs. In Orphic Argonautica, her mother is called Asterope instead. Her brothers were Aeëtes, keeper of the Golden Fleece and father of Medea, and Perses. Her sister was Pasiphaë, the wife of King Minos and mother of the Minotaur. Other accounts make her and her niece Medea the daughters of Hecate, the goddess of witchcraft by Aeëtes, usually said to be her brother instead. She was often confused with Calypso, due to her shifts in behavior and personality, and the association that both of them had with Odysseus.
According to Greek legend, Circe lived on the island of Aeaea. Although Homer is vague when it comes to the island's whereabouts, in his epic poem Argonautica, the early 3rd BC author Apollonius of Rhodes locates Aeaea somewhere south of Aethalia (Elba), within view of the Tyrrhenian shore (that is, the western coast of Italy). In the same poem, Circe's brother Aeëtes describes how Circe was transferred to Aeaea: "I noted it once after taking a ride in my father Helios' chariot, when he was taking my sister Circe to the western land and we came to the coast of the Tyrrhenian mainland, where she dwells to this day, very far from the Colchian land." A scholiast on Apollonius Rhodius claims that Apollonius is following Hesiod's tradition in making Circe arrive in Aeaea on Helios' chariot, while Valerius Flaccus writes that Circe was borne away by winged dragons. Roman poets associated her with the most ancient traditions of Latium, and made her home to be on the promontory of Circeo.
Homer describes Circe as "a dreadful goddess with lovely hair and human speech". Apollonius writes that she (just like every other descendant of Helios) had flashing golden eyes that shot out rays of light, with the author of Argonautica Orphica noting that she had hair like fiery rays. Ovid's The Cure for Love implies that Circe might have been taught the knowledge of herbs and potions from her mother Perse, who seems to have had similar skills.
In the Argonautica, Apollonius relates that Circe purified the Argonauts for the murder of Medea's brother Absyrtus, possibly reflecting an early tradition. In this poem, the Argonauts find Circe bathing in salt water; the animals that surround her are not former lovers transformed but primeval "beasts, not resembling the beasts of the wild, nor yet like men in body, but with a medley of limbs." Circe invites Jason, Medea and their crew into her mansion; uttering no words, they show her the still bloody sword they used to cut Absyrtus down, and Circe immediately realizes they have visited her to be purified of murder. She purifies them by slitting the throat of a suckling pig and letting the blood drip on them. Afterwards, Medea tells Circe their tale in great detail, albeit omitting the part of Absyrtus' murder; nevertheless Circe is not fooled, and greatly disapproves of their actions. However, out of pity for the girl, and on account of their kinship, she promises not to be an obstacle on their way, and orders Jason and Medea to leave her island immediately.
The sea-god Glaucus was in love with a beautiful maiden, Scylla, but she spurned his affections no matter how he tried to win her heart. Glaucus went to Circe, and asked her for a magic potion to make Scylla fall in love with him too. But Circe was smitten by Glaucus herself, and fell in love with him. Glaucus did not love her back, and turned down her offer of marriage. Enraged, Circe used her knowledge of herbs and plants to take her revenge; she found the spot where Scylla usually took her bath, and poisoned the water. When Scylla went down to it to bathe, dogs sprang from her thighs and she was transformed into the familiar monster from the Odyssey. In another, similar story, Picus was a Latian king whom Circe turned into a woodpecker. He was the son of Saturn, and a king of Latium. He fell in love and married a nymph, Canens, to whom he was utterly devoted. One day as he was hunting boars, he came upon Circe, who was gathering herbs in the woods. Circe fell immediately in love with him; but Picus, just like Glaucus before him, spurned her and declared that he would remain forever faithful to Canens. Circe, furious, turned Picus into a woodpecker. His wife Canens eventually wasted away in her mourning.
During the war between the gods and the giants, one of the giants, Picolous, fled the battle against the gods and came to Aeaea, Circe's island. He attempted to chase Circe away, only to be killed by Helios, Circe's ally and father. From the blood of the slain giant an herb came into existence; moly, named thus from the battle (malos) and with a white-coloured flower, either for the white Sun who had killed Picolous or the terrified Circe who turned white; the very plant, which mortals are unable to pluck from the ground, that Hermes would later give to Odysseus in order to defeat Circe.
In Homer's Odyssey, an 8th-century BC sequel to his Trojan War epic Iliad, Circe is initially described as a beautiful goddess living in a palace isolated in the midst of a dense wood on her island of Aeaea. Around her home prowl strangely docile lions and wolves. She lures any who land on the island to her home with her lovely singing while weaving on an enormous loom, but later drugs them so that they change shape. One of her Homeric epithets is polypharmakos, "knowing many drugs or charms".
Circe invites the hero Odysseus' crew to a feast of familiar food, a pottage of cheese and meal, sweetened with honey and laced with wine, but also mixed with one of her magical potions that turns them into swine. Only Eurylochus, who suspects treachery, does not go in. He escapes to warn Odysseus and the others who have remained with the ship. Before Odysseus reaches Circe's palace, Hermes, the messenger god sent by the goddess of wisdom Athena, intercepts him and reveals how he might defeat Circe in order to free his crew from their enchantment. Hermes provides Odysseus with moly to protect him from Circe's magic. He also tells Odysseus that he must then draw his sword and act as if he were going to attack her. From there, as Hermes foretold, Circe would ask Odysseus to bed, but Hermes advises caution, for the treacherous goddess could still "unman" him unless he has her swear by the names of the gods that she will not take any further action against him. Following this advice, Odysseus is able to free his men.
After they have all remained on the island for a year, Circe advises Odysseus that he must first visit the Underworld, something a mortal has never yet done, in order to gain knowledge about how to appease the gods, return home safely and recover his kingdom. Circe also advises him on how this might be achieved and furnishes him with the protections he will need and the means to communicate with the dead. On his return, she further advises him about two possible routes home, warning him, however, that both carry great danger.
Towards the end of Hesiod's Theogony (c. 700 BC), it is stated that Circe bore Odysseus three sons: Agrius (otherwise unknown); Latinus; and Telegonus, who ruled over the Tyrsenoi, that is the Etruscans. The Telegony, an epic now lost, relates the later history of the last of these. Circe eventually informed her son who his absent father was and, when he set out to find Odysseus, gave him a poisoned spear. When Telegonus arrived in Ithaca, Odysseus was away in Thesprotia, fighting the Brygi. Telegonus began to ravage the island; Odysseus came to defend his land. With the weapon Circe gave him, Telegonus killed his father unknowingly. Telegonus then brought back his father's corpse to Aeaea, together with Penelope and Odysseus' son by her, Telemachus. After burying Odysseus, Circe made the other three immortal.
Circe married Telemachus, and Telegonus married Penelope by the advice of Athena. According to an alternative version depicted in Lycophron's 3rd-century BC poem Alexandra (and John Tzetzes' scholia on it), Circe used magical herbs to bring Odysseus back to life after he had been killed by Telegonus. Odysseus then gave Telemachus to Circe's daughter Cassiphone in marriage. Sometime later, Telemachus had a quarrel with his mother-in-law and killed her; Cassiphone then killed Telemachus to avenge her mother's death. On hearing of this, Odysseus died of grief.
Dionysius of Halicarnassus (1.72.5) cites Xenagoras, the 2nd-century BC historian, as claiming that Odysseus and Circe had three different sons: Rhomos, Anteias, and Ardeias, who respectively founded three cities called by their names: Rome, Antium, and Ardea.
In the later 5th-century CE epic Dionysiaca, its author Nonnus mentions Phaunus, Circe's son by the sea god Poseidon.
Three ancient plays about Circe have been lost: the work of the tragedian Aeschylus and of the 4th-century BC comic dramatists Ephippus of Athens and Anaxilas. The first told the story of Odysseus' encounter with Circe. Vase paintings from the period suggest that Odysseus' half-transformed animal-men formed the chorus in place of the usual Satyrs. Fragments of Anaxilas also mention the transformation and one of the characters complains of the impossibility of scratching his face now that he is a pig.
The theme of Circe turning men into a variety of animals was elaborated by later writers. In his episodic work The Sorrows of Love (first century BC), Parthenius of Nicaea interpolated another episode into the time that Odysseus was staying with Circe. Pestered by the amorous attentions of King Calchus the Daunian, the sorceress invited him to a drugged dinner that turned him into a pig and then shut him up in her sties. He was only released when his army came searching for him on the condition that he would never set foot on her island again.
Among Latin treatments, Virgil's Aeneid relates how Aeneas skirts the Italian island where Circe dwells and hears the cries of her many male victims, who now number more than the pigs of earlier accounts: The roars of lions that refuse the chain, / The grunts of bristled boars, and groans of bears, / And herds of howling wolves that stun the sailors' ears. In Ovid's 1st-century poem Metamorphoses, the fourth episode covers Circe's encounter with Ulysses (the Roman name of Odysseus), whereas book 14 covers the stories of Picus and Glaucus.
Plutarch took up the theme in a lively dialogue that was later to have several imitators. Contained in his 1st-century Moralia is the Gryllus episode in which Circe allows Odysseus to interview a fellow Greek turned into a pig. After his interlocutor informs Odysseus that his present existence is preferable to the human, they engage in a philosophical dialogue in which every human value is questioned and beasts are proved to be of superior wisdom and virtue.
Strabo writes that a tomb-shrine of Circe was attended in one of the Pharmacussae islands, off the coast of Attica, typical for hero-worship. Circe was also venerated in Mount Circeo, in the Italian peninsula, which took its name after her according to ancient legend. Strabo says that Circe had a shrine in the small town, and that the people there kept a bowl they claimed belonged to Odysseus. The promontory is occupied by ruins of a platform attributed with great probability to a temple of Venus or Circe.
Giovanni Boccaccio provided a digest of what was known of Circe during the Middle Ages in his De mulieribus claris (Famous Women, 1361–1362). While following the tradition that she lived in Italy, he comments wryly that there are now many more temptresses like her to lead men astray.
There is a very different interpretation of the encounter with Circe in John Gower's long didactic poem Confessio Amantis (1380). Ulysses is depicted as deeper in sorcery and readier of tongue than Circe and through this means he leaves her pregnant with Telegonus. Most of the account deals with the son's later quest for and accidental killing of his father, drawing the moral that only evil can come of the use of sorcery.
The story of Ulysses and Circe was retold as an episode in Georg Rollenhagen's German verse epic, Froschmeuseler (The Frogs and Mice, Magdeburg, 1595). In this 600-page expansion of the pseudo-Homeric Batrachomyomachia, it is related at the court of the mice and takes up sections 5–8 of the first part.
In Lope de Vega's miscellany La Circe – con otras rimas y prosas (1624), the story of her encounter with Ulysses appears as a verse epic in three cantos. This takes its beginning from Homer's account, but it is then embroidered; in particular, Circe's love for Ulysses remains unrequited.
As "Circe's Palace", Nathaniel Hawthorne retold the Homeric account as the third section in his collection of stories from Greek mythology, Tanglewood Tales (1853). The transformed Picus continually appears in this, trying to warn Ulysses, and then Eurylochus, of the danger to be found in the palace, and is rewarded at the end by being given back his human shape. In most accounts Ulysses only demands this for his own men.
In her survey of the Transformations of Circe, Judith Yarnall comments of this figure, who started out as a comparatively minor goddess of unclear origin, that "What we know for certain – what Western literature attests to – is her remarkable staying power…These different versions of Circe's myth can be seen as mirrors, sometimes clouded and sometimes clear, of the fantasies and assumptions of the cultures that produced them." After appearing as just one of the characters that Odysseus encounters on his wandering, "Circe herself, in the twists and turns of her story through the centuries, has gone through far more metamorphoses than those she inflicted on Odysseus's companions."
One of the most enduring literary themes connected with the figure of Circe was her ability to change men into animals. There was much speculation concerning how this could be, whether the human consciousness changed at the same time, and even whether it was a change for the better. The Gryllus dialogue was taken up by another Italian writer, Giovan Battista Gelli, in his La Circe (1549). This is a series of ten philosophical and moral dialogues between Ulysses and the humans transformed into various animals, ranging from an oyster to an elephant, in which Circe sometimes joins. Most argue against changing back; only the last animal, a philosopher in its former existence, wants to. The work was translated into English soon after in 1557 by Henry Iden. Later the English poet Edmund Spenser also made reference to Plutarch's dialogue in the section of his Faerie Queene (1590) based on the Circe episode which appears at the end of Book II. Sir Guyon changes back the victims of Acrasia's erotic frenzy in the Bower of Bliss, most of whom are abashed at their fall from chivalric grace, But one above the rest in speciall, / That had an hog beene late, hight Grille by name, / Repined greatly, and did him miscall, / That had from hoggish forme him brought to naturall.
Two other Italians wrote rather different works that centre on the animal within the human. One was Niccolò Machiavelli in his unfinished long poem, L'asino d'oro (The Golden Ass, 1516). The author meets a beautiful herdswoman surrounded by Circe's herd of beasts. After spending a night of love with him, she explains the characteristics of the animals in her charge: the lions are the brave, the bears are the violent, the wolves are those forever dissatisfied, and so on (Canto 6). In Canto 7 he is introduced to those who experience frustration: a cat that has allowed its prey to escape; an agitated dragon; a fox constantly on the look-out for traps; a dog that bays the moon; Aesop's lion in love that allowed himself to be deprived of his teeth and claws. There are also emblematic satirical portraits of various Florentine personalities. In the eighth and last canto he has a conversation with a pig that, like the Gryllus of Plutarch, does not want to be changed back and condemns human greed, cruelty and conceit.
The other Italian author was the esoteric philosopher Giordano Bruno, who wrote in Latin. His Cantus Circaeus (The Incantation of Circe) was the fourth work on memory and the association of ideas by him to be published in 1582. It contains a series of poetic dialogues, in the first of which, after a long series of incantations to the seven planets of the Hermetic tradition, most humans appear changed into different creatures in the scrying bowl. The sorceress Circe is then asked by her handmaiden Moeris about the type of behaviour with which each is associated. According to Circe, for instance, fireflies are the learned, wise, and illustrious amidst idiots, asses, and obscure men (Question 32). In later sections different characters discuss the use of images in the imagination in order to facilitate use of the art of memory, which is the real aim of the work.
French writers were to take their lead from Gelli in the following century. Antoine Jacob wrote a one-act social comedy in rhyme, Les Bestes raisonnables (The Reasoning Beasts, 1661) which allowed him to satirise contemporary manners. On the isle of Circe, Ulysses encounters an ass that was once a doctor, a lion that had been a valet, a female doe and a horse, all of whom denounce the decadence of the times. The ass sees human asses everywhere, Asses in the town square, asses in the suburbs, / Asses in the provinces, asses proud at court, / Asses browsing in the meadows, military asses trooping, / Asses tripping it at balls, asses in the theatre stalls. To drive the point home, in the end it is only the horse, formerly a courtesan, who wants to return to her former state.
The same theme occupies La Fontaine's late fable, "The Companions of Ulysses" (XII.1, 1690), which also echoes Plutarch and Gelli. Once transformed, every animal (which includes a lion, a bear, a wolf and a mole) protests that their lot is better and refuses to be restored to human shape. Charles Dennis shifted this fable to stand at the head of his translation of La Fontaine, Select Fables (1754), but provides his own conclusion that When Mortals from the path of Honour stray, / And the strong passions over reason sway, / What are they then but Brutes? / 'Tis vice alone that constitutes / Th'enchanting wand and magic bowl, The exterior form of Man they wear, / But are in fact both Wolf and Bear, / The transformation's in the Soul.
Louis Fuzelier and Marc-Antoine Legrand titled their comic opera of 1718 Les animaux raisonnables. It had more or less the same scenario transposed into another medium and set to music by Jacques Aubert. Circe, wishing to be rid of the company of Ulysses, agrees to change back his companions, but only the dolphin is willing. The others, who were formerly a corrupt judge (now a wolf), a financier (a pig), an abused wife (a hen), a deceived husband (a bull) and a flibbertigibbet (a linnet), find their present existence more agreeable.
The Venetian Gasparo Gozzi was another Italian who returned to Gelli for inspiration in the 14 prose Dialoghi dell'isola di Circe (Dialogues from Circe's Island) published as journalistic pieces between 1760 and 1764. In this moral work, the aim of Ulysses in talking to the beasts is to learn more of the human condition. It includes figures from fable (The fox and the crow, XIII) and from myth to illustrate its vision of society at variance. Far from needing the intervention of Circe, the victims find their natural condition as soon as they set foot on the island. The philosopher here is not Gelli's elephant but the bat that retreats from human contact into the darkness, like Bruno's fireflies (VI). The only one who wishes to change in Gozzi's work is the bear, a satirist who had dared to criticize Circe and had been changed as a punishment (IX).
There were two more satirical dramas in later centuries. One modelled on the Gryllus episode in Plutarch occurs as a chapter of Thomas Love Peacock's late novel, Gryll Grange (1861), under the title "Aristophanes in London". Half Greek comedy, half Elizabethan masque, it is acted at the Grange by the novel's characters as a Christmas entertainment. In it Spiritualist mediums raise Circe and Gryllus and try to convince the latter of the superiority of modern times, which he rejects as intellectually and materially regressive. An Italian work drawing on the transformation theme was the comedy by Ettore Romagnoli, La figlia del Sole (The Daughter of the Sun, 1919). Hercules arrives on the island of Circe with his servant Cercopo and has to be rescued by the latter when he too is changed into a pig. But, since the naturally innocent other animals had become corrupted by imitating human vices, the others who had been changed were refused when they begged to be rescued.
Also in England, Austin Dobson engaged more seriously with Homer's account of the transformation of Odysseus' companions when, though Head, face and members bristle into swine, / Still cursed with sense, their mind remains alone. Dobson's "The Prayer of the Swine to Circe" (1640) depicts the horror of being imprisoned in an animal body in this way with the human consciousness unchanged. There appears to be no relief, for only in the final line is it revealed that Odysseus has arrived to free them. But in Matthew Arnold's dramatic poem "The Strayed Reveller" (1849), in which Circe is one of the characters, the power of her potion is differently interpreted. The inner tendencies unlocked by it are not the choice between animal nature and reason but between two types of impersonality, between divine clarity and the poet's participatory and tragic vision of life. In the poem, Circe discovers a youth laid asleep in the portico of her temple by a draught of her ivy-wreathed bowl. On awaking from possession by the poetic frenzy it has induced, he craves for it to be continued.
With the Renaissance there began to be a reinterpretation of what it was that changed the men, if it was not simply magic. For Socrates, in Classical times, it had been gluttony overcoming their self-control. But for the influential emblematist Andrea Alciato, it was unchastity. In the second edition of his Emblemata (1546), therefore, Circe became the type of the prostitute. His Emblem 76 is titled Cavendum a meretricibus; its accompanying Latin verses mention Picus, Scylla and the companions of Ulysses, and concludes that 'Circe with her famous name indicates a whore and any who loves such a one loses his reason'. His English imitator Geoffrey Whitney used a variation of Alciato's illustration in his own Choice of Emblemes (1586) but gave it the new title of Homines voluptatibus transformantur, men are transformed by their passions. This explains her appearance in the Nighttown section named after her in James Joyce's novel Ulysses. Written in the form of a stage script, it makes of Circe the brothel madam, Bella Cohen. Bloom, the book's protagonist, fantasizes that she turns into a cruel man-tamer named Mr Bello who makes him get down on all fours and rides him like a horse.
By the 19th century, Circe was ceasing to be a mythical figure. Poets treated her either as an individual or at least as the type of a certain kind of woman. The French poet Albert Glatigny addresses "Circé" in his Les vignes folles (1857) and makes of her a voluptuous opium dream, the magnet of masochistic fantasies. Louis-Nicolas Ménard's sonnet in Rêveries d'un païen mystique (1876) describes her as enchanting all with her virginal look, but appearance belies the accursed reality. Poets in English were not far behind in this lurid portrayal. Lord de Tabley's "Circe" (1895) is a thing of decadent perversity likened to a tulip, A flaunting bloom, naked and undivine... / With freckled cheeks and splotch'd side serpentine, / A gipsy among flowers.
That central image is echoed by the blood-striped flower of T.S.Eliot's student poem "Circe's Palace" (1909) in the Harvard Advocate. Circe herself does not appear, her character is suggested by what is in the grounds and the beasts in the forest beyond: panthers, pythons, and peacocks that look at us with the eyes of men whom we knew long ago. Rather than a temptress, she has become an emasculatory threat.
Several female poets make Circe stand up for herself, using the soliloquy form to voice the woman's position. The 19th-century English poet Augusta Webster, much of whose writing explored the female condition, has a dramatic monologue in blank verse titled "Circe" in her volume Portraits (1870). There the sorceress anticipates her meeting with Ulysses and his men and insists that she does not turn men into pigs—she merely takes away the disguise that makes them seem human. But any draught, pure water, natural wine, / out of my cup, revealed them to themselves / and to each other. Change? there was no change; / only disguise gone from them unawares. The mythological character of the speaker contributes at a safe remove to the Victorian discourse on women's sexuality by expressing female desire and criticizing the subordinate role given to women in heterosexual politics.
Two American poets also explored feminine psychology in poems ostensibly about the enchantress. Leigh Gordon Giltner's "Circe" was included in her collection The Path of Dreams (1900), the first stanza of which relates the usual story of men turned into swine by her spell. But then a second stanza presents a sensuous portrait of an unnamed woman, very much in the French vein; once more, it concludes, 'A Circe's spells transform men into swine'. This is no passive victim of male projections but a woman conscious of her sexual power. So too is H.D.'s "Circe", from her collection Hymen (1921). In her soliloquy she reviews the conquests with which she has grown bored, then mourns the one instance when she failed. In not naming Ulysses himself, Doolittle universalises an emotion with which all women might identify. At the end of the century, British poet Carol Ann Duffy wrote a monologue entitled Circe which pictures the goddess addressing an audience of 'nereids and nymphs'. In this outspoken episode in the war between the sexes, Circe describes the various ways in which all parts of a pig could and should be cooked.
Another indication of the progression in interpreting the Circe figure is given by two poems a century apart, both of which engage with paintings of her. The first is the sonnet that Dante Gabriel Rossetti wrote in response to Edward Burne-Jones' "The Wine of Circe" in his volume Poems (1870). It gives a faithful depiction of the painting's Pre-Raphaelite mannerism but its description of Circe's potion as 'distilled of death and shame' also accords with the contemporary (male) identification of Circe with perversity. This is further underlined by his statement (in a letter) that the black panthers there are 'images of ruined passion' and by his anticipation at the end of the poem of passion's tide-strown shore / Where the disheveled seaweed hates the sea. The Australian A. D. Hope's "Circe – after the painting by Dosso Dossi", on the other hand, frankly admits humanity's animal inheritance as natural and something in which even Circe shares. In the poem, he links the fading rationality and speech of her lovers to her own animal cries in the act of love.
There remain some poems that bear her name that have more to do with their writers' private preoccupations than with reinterpreting her myth. The link with it in Margaret Atwood's "Circe/Mud Poems", first published in You Are Happy (1974), is more a matter of allusion and is nowhere overtly stated beyond the title. It is a reflection on contemporary gender politics that scarcely needs the disguises of Augusta Webster's. With two other poems by male writers it is much the same: Louis Macneice's, for example, whose "Circe" appeared in his first volume, Poems (London, 1935); or Robert Lowell's, whose "Ulysses and Circe" appeared in his last, Day by Day (New York, 1977). Both poets have appropriated the myth to make a personal statement about their broken relationships.
Several Renaissance epics of the 16th century include lascivious sorceresses based on the Circe figure. These generally live in an isolated spot devoted to pleasure, to which lovers are lured and later changed into beasts. They include the following:
Later scholarship has identified elements from the character of both Circe and especially her fellow enchantress Medea as contributing to the development of the mediaeval legend of Morgan le Fay. In addition, it has been argued that the fairy Titania in William Shakespeare's A Midsummer Night's Dream (1600) is an inversion of Circe. Titania (daughter of the Titans) was a title by which the sorceress was known in Classical times. In this case the tables are turned on the character, who is queen of the fairies. She is made to love an ass after, rather than before, he is transformed into his true animal likeness.
It has further been suggested that John Milton's Mask Presented at Ludlow Castle (1634) is a sequel to Tempe Restored, a masque in which Circe had figured two years earlier, and that the situation presented there is a reversal of the Greek myth. At the start of the masque, the character Comus is described as the son of Circe by Bacchus, god of wine, and the equal of his mother in enchantment. He too changes travelers into beastly forms that 'roll with pleasure in a sensual sty'. Having waylaid the heroine and immobilized her on an enchanted chair, he stands over her, wand in hand, and presses on her a magical cup (representing sexual pleasure and intemperance), which she repeatedly refuses, arguing for the virtuousness of temperance and chastity. The picture presented is a mirror image of the Classical story. In place of the witch who easily seduces the men she meets, a male enchanter is resisted by female virtue.
In the 20th century, the Circe episode was to be re-evaluated in two poetic sequels to the Odyssey. In the first of these, Giovanni Pascoli's L'Ultimo Viaggio (The Last Voyage, 1906), the aging hero sets out to rediscover the emotions of his youth by retracing his journey from Troy, only to discover that the island of Eea is deserted. What in his dream of love he had taken for the roaring of lions and Circe's song was now no more than the sound of the sea-wind in autumnal oaks (Cantos 16–17).
This melancholy dispelling of illusion is echoed in The Odyssey: A Modern Sequel (1938) by Nikos Kazantzakis. The fresh voyage in search of new meaning to life recorded there grows out of the hero's initial rejection of his past experiences in the first two sections. The Circe episode is viewed by him as a narrow escape from death of the spirit: With twisted hands and thighs we rolled on burning sands, / a hanging mess of hissing vipers glued in sun!... / Farewell the brilliant voyage, ended! Prow and soul / moored in the muddy port of the contented beast! / O prodigal, much-traveled soul, is this your country? His escape from this mire of sensuality comes one day when the sight of some fishermen, a mother and her baby enjoying the simple comforts of food and drink, recalls him to life, its duties and delights. Where the attempt by Pascoli's hero to recapture the past ended in failure, Kazantzakis' Odysseus, already realising the emptiness of his experiences, journeys into what he hopes will be a fuller future.
Scenes from the Odyssey are common on Greek pottery, the Circe episode among them. The two most common representations have Circe surrounded by the transformed sailors and Odysseus threatening the sorceress with his sword. In the case of the former, the animals are not always boars but also include, for instance, the ram, dog and lion on the 6th-century BC Boston kylix. Often the transformation is only partial, involving the head and perhaps a sprouting tail, while the rest of the body is human. In describing an otherwise obscure 5th-century Greek bronze in the Walters Art Museum that takes the form of a man on all fours with the foreparts of a pig, the commentator asks in what other way could an artist depict someone bewitched other than as a man with an animal head. In these scenes Circe is shown almost invariably stirring the potion with her wand, although the incident as described in Homer has her use the wand only to bewitch the sailors after they have refreshed themselves. One exception is the Berlin amphora on which the seated Circe holds the wand towards a half transformed man.
In the second scene, Odysseus threatens the sorceress with a drawn sword, as Homer describes it. However, he is sometimes depicted carrying spears as well, as in the Athens lekythos, while Homer reports that it was a bow he had slung over his shoulder. In this episode Circe is generally shown in flight, and on the Erlangen lekythos can clearly be seen dropping the bowl and wand behind her. Two curiously primitive wine bowls incorporate the Homeric detail of Circe's handloom, at which the men approaching her palace could hear her singing sweetly as she worked. In the 5th-century skyphos from Boeotia an apparently crippled Odysseus leans on a crutch while a woman with African features holds out a disproportionately large bowl. In the other, a pot-bellied hero brandishes a sword while Circe stirs her potion. Both these may depict the scene as represented in one or other of the comic satyr plays which deal with their encounter. Little remains of these now beyond a few lines by Aeschylus, Ephippus of Athens and Anaxilas. Other vase paintings from the period suggest that Odysseus' half-transformed animal-men formed the chorus in place of the usual satyrs. The reason that it should be a subject of such plays is that wine drinking was often central to their plot. Later writers were to follow Socrates in interpreting the episode as illustrating the dangers of drunkenness.
Other artefacts depicting the story include the chest of Cypselus described in the travelogue by Pausanias. Among its many carvings 'there is a grotto and in it a woman sleeping with a man upon a couch. I was of opinion that they were Odysseus and Circe, basing my view upon the number of the handmaidens in front of the grotto and upon what they are doing. For the women are four, and they are engaged on the tasks which Homer mentions in his poetry'. The passage in question describes how one of them 'threw linen covers over the chairs and spread fine purple fabrics on top. Another drew silver tables up to the chairs, and laid out golden dishes, while a third mixed sweet honeyed wine in a silver bowl, and served it in golden cups. The fourth fetched water and lit a roaring fire beneath a huge cauldron'. This suggests a work of considerable detail, while the Etruscan coffin preserved in Orvieto's archaeological museum has only four figures. At the centre Odysseus threatens Circe with drawn sword while an animal headed figure stands on either side, one of them laying his hand familiarly on the hero's shoulder. A bronze mirror relief in the Fitzwilliam Museum is also Etruscan and is inscribed with the names of the characters. There a pig is depicted at Circe's feet, while Odysseus and Elpenor approach her, swords drawn.
During the 18th century painters began to portray individual actors in scenes from named plays. There was also a tradition of private performances, with a variety of illustrated works to help with stage properties and costumes. Among these was Thomas Jefferys' A Collection of the Dresses of Different Nations, Antient and Modern (1757–72) which included a copperplate engraving of a crowned Circe in loose dress, holding a goblet aloft in her right hand and a long wand in her left. Evidence of such performances during the following decades is provided by several portraits in character, of which one of the earliest was the pastel by Daniel Gardner (1750–1805) of "Miss Elliot as Circe". The artist had been a pupil of both George Romney and Joshua Reynolds, who themselves were soon to follow his example. On the 1778 engraving based on Gardner's portrait appear the lines from Milton's Comus: The daughter of the Sun, whose charmed cup / Whoever tasted, lost his upright shape / And downward fell into a grovelling swine, in compliment to the charm of this marriageable daughter of a country house. As in the Jefferys' plate, she wears a silver coronet over tumbled dark hair, with a wand in the right hand and a goblet in the left. In hindsight the frank eyes that look directly at the viewer and the rosebud mouth are too innocent for the role Miss Elliot is playing.
The subjects of later paintings impersonating Circe have a history of sexual experience behind them, starting with "Mary Spencer in the character of Circe" by William Caddick, which was exhibited at the Royal Academy in 1780. The subject here was the mistress of the painter George Stubbs. A portrait of "Mrs Nesbitt as Circe" by Reynolds followed in 1781. Though this lady's past was ambiguous, she had connections with those in power and was used by the Government as a secret agent. In the painting she is seated sideways, wearing a white, loose-fitting dress, with a wand in her right hand and a gilded goblet near her left. A monkey is crouching above her in the branches of a tree and a panther fraternizes with the kitten on her knee. While the painting undoubtedly alludes to her reputation, it also places itself within the tradition of dressing up in character.
Soon afterwards, the notorious Emma Hamilton was to raise this to an art form, partly by the aid of George Romney's many paintings of her impersonations. Romney's preliminary study of Emma's head and shoulders, at present in the Tate Gallery, with its piled hair, expressive eyes and mouth, is reminiscent of Samuel Gardener's portrait of Miss Elliot. In the full-length "Lady Hamilton as Circe" at Waddesdon Manor, she is placed in a wooded landscape with wolves snarling to her left, although the tiger originally there has now been painted out. Her left arm is raised to cast a spell while the wand points downward in her right. After Emma moved to Naples and joined Lord Hamilton, she developed what she called her "Attitudes" into a more public entertainment. Specially designed, loose-fitting tunics were paired with large shawls or veils as she posed in such a way as to evoke figures from Classical mythology. These developed from mere poses, with the audience guessing the names of the classical characters and scenes that she portrayed, into small, wordless charades.
The tradition of dressing up in character continued into the following centuries. One of the photographic series by Julia Margaret Cameron, a pupil of the painter George Frederic Watts, was of mythical characters, for whom she used the children of friends and servants as models. Young Kate Keown sat for the head of "Circe" in about 1865 and is pictured wearing a grape and vineleaf headdress to suggest the character's use of wine to bring a change in personality. The society portrait photographer Yevonde Middleton, also known as Madame Yevonde, was to use a 1935 aristocratic charity ball as the foundation for her own series of mythological portraits in colour. Its participants were invited to her studio afterwards to pose in their costumes. There Baroness Dacre is pictured as Circe with a leafy headdress about golden ringlets and clasping a large Baroque porcelain goblet.
A decade earlier, the illustrator Charles Edmund Brock extended into the 20th century what is almost a pastiche of the 18th-century conversation piece in his "Circe and the Sirens" (1925). In this the Honourable Edith Chaplin (1878–1959), Marchioness of Londonderry, and her three youngest daughters are pictured in a garden setting grouped about a large pet goat. Three women painters also produced portraits using the convention of the sitter in character. The earliest was Beatrice Offor (1864–1920), whose sitter's part in her 1911 painting of Circe is suggested by the vine-leaf crown in her long dark hair, the snake-twined goblet she carries and the snake bracelet on her left arm. Mary Cecil Allen was of Australian origin but was living in the United States at the time "Miss Audrey Stevenson as Circe" was painted (1930). Though only a head and shoulders sketch, its colouring and execution suggest the sitter's lively personality. Rosemary Valodon (born 1947), from the same country, painted a series of Australian personalities in her goddess series. "Margarita Georgiadis as Circe" (1991) is a triptych, the central panel of which portrays an updated, naked femme fatale reclining in tropical vegetation next to a pig's head.
One painting at least depicts an actress playing the part of Circe. This is Franz von Stuck's striking portrait of Tilla Durieux as Circe (1913). She played this part in a Viennese revival of Calderon's play in 1912 and there is a publicity still of her by Isidor Hirsch in which she is draped across a sofa and wearing an elaborate crown. Her enticing expression and the turn of her head there is almost exactly that of Van Stuck's enchantress as she holds out the poisoned bowl. It suggests the use of certain posed publicity photos in creating the same iconic effect as had paintings in the past. A nearly contemporary example was the 1907 photo of Mme Geneviève Vix as Circe in the light opera by Lucien Hillenacher at the Opéra-Comique in Paris. The posing of the actress and the cropping of the image so as to highlight her luxurious costume demonstrates its ambition to create an effect that goes beyond the merely theatrical. A later example is the still of Silvana Mangano in her part as Circe in the 1954 film Ulysses, which is as cunningly posed for effect.
Beside the verse dramas, with their lyrical interludes, on which many operas were based, there were poetic texts which were set as secular cantatas. One of the earliest was Alessandro Stradella's La Circe, in a setting for three voices that bordered on the operatic. It was first performed at Frascati in 1667 to honour Cardinal Leopoldo de Medici and contained references to its surroundings. In the opening recitative, Circe explains that it was her son Telegonus who founded Frascati. The other characters with whom she enters into dialogue are the south wind (Zeffiro) and the local river Algido. In the following century, Antonio Vivaldi's cantata All'ombra di sospetto (In the shadow of doubt, RV 678) is set for a single voice and depicts Circe addressing Ulysses. The countertenor part is accompanied by flute, harpsichord, cello, and theorbo and features two recitatives and two arias. The piece is famous for the dialogue created between flute and voice, conjuring the moment of flirtation before the two become lovers.
The most successful treatment of the Ulysses episode in French was Jean-Baptiste Rousseau's poem Circé (1703), that was specifically written to be a cantata. The different verse forms employed allow the piece to be divided by the musicians that set it in order to express a variety of emotions. The poem opens with the abandoned Circe sitting on a high mountain and mourning the departure of Ulysses. The sorceress then calls on the infernal gods and makes a terrible sacrifice: A myriad vapours obscure the light, / The stars of the night interrupt their course, / Astonished rivers retreat to their source / And even Death's god trembles in the dark. But though the earth is shaken to its core, Love is not to be commanded in this way and the wintery fields come back to life.
The earliest setting was by Jean-Baptiste Morin in 1706 and was popular for most of the rest of the century. One of its final moralising minuets, Ce n'est point par effort qu'on aime (Love won't be forced) was often performed independently and the score reprinted in many song collections. The flautist Michel Blavet arranged the music for this and the poem's final stanza, Dans les champs que l'Hiver désole (In the fields that Winter wastes), for two flutes in 1720. The new setting of the cantata three years later by Francois Collin de Blamont was equally successful and made the name of its nineteen-year-old composer. Originally for voice and bass continuo, it was expanded and considerably revised in 1729, with parts for flute, violin and viol added. Towards the end of the century, the choral setting by Georges Granges de Fontenelle (1769–1819) was equally to bring its young composer fame.
Rousseau's poem was also familiar to composers of other nationalities. Set for mezzo-soprano and full orchestra, it was given almost operatic treatment by the court composer Luigi Cherubini in 1789. Franz Seydelmann set it for soprano and full orchestra in Dresden in 1787 at the request of the Russian ambassador to the Saxon Court, Prince Alexander Belosselsky, who spoke highly of Seydelmann's work. A later setting by Austrian composer Sigismond von Neukomm for soprano and full orchestra (Op. 4, 1810) was judged favorably by French musicologist Jacques Chailley in his 1966 article for the journal Revue des études slaves.
Recent treatments of the Circe theme include the Irish composer Gerard Victory's radio cantata Circe 1991 (1973–75), David Gribble's A Threepenny Odyssey, a fifteen-minute cantata for young people which includes the episode on Circe's Isle, and Malcolm Hayes' Odysseus remembers (2003–04), which includes parts for Circe, Anticleia and Tiresias. Gerald Humel's song cycle Circe (1998) grew out of his work on his 1993 ballet with Thomas Höft. The latter subsequently wrote seven poems in German featuring Circe's role as seductress in a new light: here it is to freedom and enlightenment that she tempts her hearers. Another cycle of Seven Songs for High Voice and Piano (2008) by the American composer Martin Hennessey includes the poem "Circe's Power" from Louise Glück's Meadowlands (1997).
There have also been treatments of Circe in popular music, in particular the relation of the Odysseus episode in Friedrich Holländer's song of 1958. In addition, text in Homeric Greek is included in the "Circe's Island" episode in David Bedford's The Odyssey (1976). This was the ancestor of several later electronic suites that reference the Odysseus legend, with "Circe" titles among them, having little other programmatic connection with the myth itself.
After classical ballet separated from theatrical spectacle into a wordless form in which the story is expressed solely through movement, the subject of Circe was rarely visited. It figured as the first episode of three with mythological themes in Les Fêtes Nouvelles (New Shows), staged by Sieur Duplessis le cadet in 1734, but the work was taken off after its third performance and not revived. The choreographer Antoine Pitrot also staged Ulysse dans l'isle de Circée, describing it as a ballet sérieux, heroï-pantomime in 1764. Thereafter there seems to be nothing until the revival of ballet in the 20th century.
In 1963, the American choreographer Martha Graham created her Circe with a score by Alan Hovhaness. Its theme is psychological, representing the battle with animal instincts. The beasts portrayed extend beyond swine and include a goat, a snake, a lion and a deer. The theme has been described as one of 'highly charged erotic action', although set in 'a world where sexual frustration is rampant'. In that same decade Rudolf Brucci composed his Kirka (1967) in Croatia.
There is a Circe episode in John Harbison's Ulysses (Act 1, scene 2, 1983) in which the song of the enchantress is represented by ondes Martenot and tuned percussion. After the sailors of Ullyses are transformed into animals by her spell, a battle of wills follows between Circe and the hero. Though the men are changed back, Ulysses is charmed by her in his turn. In 1993, a full scale treatment of the story followed in Gerald Humel's two-act Circe und Odysseus. Also psychological in intent, it represents Circe's seduction of the restless hero as ultimately unsuccessful. The part played by the geometrical set in its Berlin production was particularly notable.
While operas on the subject of Circe did not cease, they were overtaken for a while by the new musical concept of the symphonic poem which, whilst it does not use a sung text, similarly seeks a union of music and drama. A number of purely musical works fall into this category from the late 19th century onwards, of which one of the first was Heinrich von Herzogenberg's Odysseus (Op.16, 1873). A Wagnerian symphony for large orchestra, dealing with the hero's return from the Trojan war, its third section is titled "Circe's Gardens" (Die Gärten der Circe).
In the 20th century, Ernst Boehe [de]'s cycle Aus Odysseus Fahrten (From Odysseus' Voyage, Op. 6, 1903) was equally programmatic and included the visit to Circe's Isle (Die Insel der Circe) as its second long section. After a depiction of the sea voyage, a bass clarinet passage introduces an ensemble of flute, harp and solo violin over a lightly orchestrated accompaniment, suggesting Circe's seductive attempt to hold Odysseus back from traveling further. Alan Hovhaness' Circe Symphony (No.18, Op. 204a, 1963) is a late example of such programmatic writing. It is, in fact, only a slightly changed version of his ballet music of that year, with the addition of more strings, a second timpanist and celesta.
With the exception of Willem Frederik Bon's prelude for orchestra (1972), most later works have been for a restricted number of instruments. They include Hendrik de Regt's Circe (Op. 44, 1975) for clarinet, violin and piano; Christian Manen's Les Enchantements De Circe (Op. 96, 1975) for bassoon and piano; and Jacques Lenot's Cir(c)é (1986) for oboe d'amore. The German experimental musician Dieter Schnebel's Circe (1988) is a work for harp, the various sections of which are titled Signale (signals), Säuseln (whispers), Verlockungen (enticements), Pein (pain), Schläge (strokes) and Umgarnen (snare), which give some idea of their programmatic intent.
Thea Musgrave's "Circe" for three flutes (1996) was eventually to become the fourth piece in her six-part Voices from the Ancient World for various combinations of flute and percussion (1998). Her note on these explains that their purpose is to 'describe some of the personages of ancient Greece' and that Circe was 'the enchantress who changed men into beasts'. A recent reference is the harpsichordist Fernando De Luca's Sonata II for viola da gamba titled "Circe's Cave" (L'antro della maga Circe).
In later Christian opinion, Circe was an abominable witch using miraculous powers to evil ends. When the existence of witches came to be questioned, she was reinterpreted as a depressive suffering from delusions.
In botany, the Circaea are plants belonging to the enchanter's nightshade genus. The name was given by botanists in the late 16th century in the belief that this was the herb used by Circe to charm Odysseus' companions. Medical historians have speculated that the transformation to pigs was not intended literally but refers to anticholinergic intoxication with the plant Datura stramonium. Symptoms include amnesia, hallucinations, and delusions. The description of "moly" fits the snowdrop, a flower that contains galantamine, which is a long lasting anticholinesterase and can therefore counteract anticholinergics that are introduced to the body after it has been consumed.
The gens Mamilia – described by Livy as one of the most distinguished families of Latium – claimed descent from Mamilia, a granddaughter of Odysseus and Circe through Telegonus. One of the most well known of them was Octavius Mamilius (died 498 BC), princeps of Tusculum and son-in-law of Lucius Tarquinius Superbus the seventh and last king of Rome. | [

In the same poem, Circe's brother Aeëtes describes how Circe was transferred to Aeaea: \"I noted it once after taking a ride in my father Helios' chariot, when he was taking my sister Circe to the western land and we came to the coast of the Tyrrhenian mainland, where she dwells to this day, very far from the Colchian land.\" A scholiast on Apollonius Rhodius claims that Apollonius is following Hesiod's tradition in making Circe arrive in Aeaea on Helios' chariot, while Valerius Flaccus writes that Circe was borne away by winged dragons.

In another, similar story, Picus was a Latian king whom Circe turned into a woodpecker. He was the son of Saturn, and a king of Latium. He fell in love and married a nymph, Canens, to whom he was utterly devoted. One day as he was hunting boars, he came upon Circe, who was gathering herbs in the woods.

This is a series of ten philosophical and moral dialogues between Ulysses and the humans transformed into various animals, ranging from an oyster to an elephant, in which Circe sometimes joins. Most argue against changing back; only the last animal, a philosopher in its former existence, wants to. The work was translated into English soon after in 1557 by Henry Iden. Later the English poet Edmund Spenser also made reference to Plutarch's dialogue in the section of his Faerie Queene (1590) based on the Circe episode which appears at the end of Book II. Sir Guyon changes back the victims of Acrasia's erotic frenzy in the Bower of Bliss, most of whom are abashed at their fall from chivalric grace, But one above the rest in speciall, / That had an hog beene late, hight Grille by name, / Repined greatly, and did him miscall, / That had from hoggish forme him brought to naturall.",

The 19th-century English poet Augusta Webster, much of whose writing explored the female condition, has a dramatic monologue in blank verse titled \"Circe\" in her volume Portraits (1870). There the sorceress anticipates her meeting with Ulysses and his men and insists that she does not turn men into pigs—she merely takes away the disguise that makes them seem human. But any draught, pure water, natural wine, / out of my cup, revealed them to themselves / and to each other. Change? there was no change; / only disguise gone from them unawares. The mythological character of the speaker contributes at a safe remove to the Victorian discourse on women's sexuality by expressing female desire and criticizing the subordinate role given to women in heterosexual politics.",

Leigh Gordon Giltner's \"Circe\" was included in her collection The Path of Dreams (1900), the first stanza of which relates the usual story of men turned into swine by her spell. But then a second stanza presents a sensuous portrait of an unnamed woman, very much in the French vein; once more, it concludes, 'A Circe's spells transform men into swine'. This is no passive victim of male projections but a woman conscious of her sexual power. So too is H.D.'s \"Circe\", from her collection Hymen (1921). In her soliloquy she reviews the conquests with which she has grown bored, then mourns the one instance when she failed. In not naming Ulysses himself, Doolittle universalises an emotion with which all women might identify. At the end of the century, British poet Carol Ann Duffy wrote a monologue entitled Circe which pictures the goddess addressing an audience of 'nereids and nymphs'. In this outspoken episode in the war between the sexes, Circe describes the various ways in which all parts of a pig could and should be cooked.",

The first is the sonnet that Dante Gabriel Rossetti wrote in response to Edward Burne-Jones' \"The Wine of Circe\" in his volume Poems (1870). It gives a faithful depiction of the painting's Pre-Raphaelite mannerism but its description of Circe's potion as 'distilled of death and shame' also accords with the contemporary (male) identification of Circe with perversity. This is further underlined by his statement (in a letter) that the black panthers there are 'images of ruined passion' and by his anticipation at the end of the poem of passion's tide-strown shore / Where the disheveled seaweed hates the sea. The Australian A. D. Hope's \"Circe – after the painting by Dosso Dossi\", on the other hand, frankly admits humanity's animal inheritance as natural and something in which even Circe shares. In the poem, he links the fading rationality and speech of her lovers to her own animal cries in the act of love.",

It is a reflection on contemporary gender politics that scarcely needs the disguises of Augusta Webster's. With two other poems by male writers it is much the same: Louis Macneice's, for example, whose \"Circe\" appeared in his first volume, Poems (London, 1935); or Robert Lowell's, whose \"Ulysses and Circe\" appeared in his last, Day by Day (New York, 1977).

He too changes travelers into beastly forms that 'roll with pleasure in a sensual sty'. Having waylaid the heroine and immobilized her on an enchanted chair, he stands over her, wand in hand, and presses on her a magical cup (representing sexual pleasure and intemperance), which she repeatedly refuses, arguing for the virtuousness of temperance and chastity.

The two most common representations have Circe surrounded by the transformed sailors and Odysseus threatening the sorceress with his sword. In the case of the former, the animals are not always boars but also include, for instance, the ram, dog and lion on the 6th-century BC Boston kylix. Often the transformation is only partial, involving the head and perhaps a sprouting tail, while the rest of the body is human. In describing an otherwise obscure 5th-century Greek bronze in the Walters Art Museum that takes the form of a man on all fours with the foreparts of a pig, the commentator asks in what other way could an artist depict someone bewitched other than as a man with an animal head. In these scenes Circe is shown almost invariably stirring the potion with her wand, although the incident as described in Homer has her use the wand only to bewitch the sailors after they have refreshed themselves. One exception is the Berlin amphora on which the seated Circe holds the wand towards a half transformed man.",

In this episode Circe is generally shown in flight, and on the Erlangen lekythos can clearly be seen dropping the bowl and wand behind her. Two curiously primitive wine bowls incorporate the Homeric detail of Circe's handloom, at which the men approaching her palace could hear her singing sweetly as she worked. In the 5th-century skyphos from Boeotia an apparently crippled Odysseus leans on a crutch while a woman with African features holds out a disproportionately large bowl. In the other, a pot-bellied hero brandishes a sword while Circe stirs her potion. Both these may depict the scene as represented in one or other of the comic satyr plays which deal with their encounter. Little remains of these now beyond a few lines by Aeschylus, Ephippus of Athens and Anaxilas. Other vase paintings from the period suggest that Odysseus' half-transformed animal-men formed the chorus in place of the usual satyrs.

Another drew silver tables up to the chairs, and laid out golden dishes, while a third mixed sweet honeyed wine in a silver bowl, and served it in golden cups. The fourth fetched water and lit a roaring fire beneath a huge cauldron'.

The artist had been a pupil of both George Romney and Joshua Reynolds, who themselves were soon to follow his example. On the 1778 engraving based on Gardner's portrait appear the lines from Milton's Comus: The daughter of the Sun, whose charmed cup / Whoever tasted, lost his upright shape / And downward fell into a grovelling swine, in compliment to the charm of this marriageable daughter of a country house. As in the Jefferys' plate, she wears a silver coronet over tumbled dark hair, with a wand in the right hand and a goblet in the left.

A nearly contemporary example was the 1907 photo of Mme Geneviève Vix as Circe in the light opera by Lucien Hillenacher at the Opéra-Comique in Paris. The posing of the actress and the cropping of the image so as to highlight her luxurious costume demonstrates its ambition to create an effect that goes beyond the merely theatrical.

] | Circe is an enchantress and a minor goddess in ancient Greek mythology and religion. In most accounts, Circe is described as the daughter of the sun god Helios and the Oceanid nymph Perse. Circe was renowned for her vast knowledge of potions and herbs. Through the use of these and a magic wand or staff, she would transform her enemies, or those who offended her, into animals. The best known of her legends is told in Homer's Odyssey when Odysseus visits her island of Aeaea on the way back from the Trojan War and she changes most of his crew into swine. He manages to persuade her to return them to human shape, lives with her for a year and has sons by her, including Latinus and Telegonus. Her ability to change others into animals is further highlighted by the story of Picus, an Italian king whom she turns into a woodpecker for resisting her advances. Another story tells of her falling in love with the sea-god Glaucus, who prefers the nymph Scylla to her. In revenge, Circe poisoned the water where her rival bathed and turned her into a dreadful monster. Depictions, even in Classical times, diverged from the detail in Homer's narrative, which was later to be reinterpreted morally as a cautionary story against drunkenness. Early philosophical questions were also raised about whether the change from being a human endowed with reason to being an unreasoning beast might not be preferable after all, and the resulting debate was to have a powerful impact during the Renaissance. Circe was also taken as the archetype of the predatory female. In the eyes of those from a later age, this behaviour made her notorious both as a magician and as a type of sexually free woman. She has been frequently depicted as such in all the arts from the Renaissance down to modern times. Western paintings established a visual iconography for the figure, but also went for inspiration to other stories concerning Circe that appear in Ovid's Metamorphoses. The episodes of Scylla and Picus added the vice of violent jealousy to her bad qualities and made her a figure of fear as well as of desire. | 2001-09-14T17:15:48Z | 2023-11-19T19:51:03Z | [

5,959 | Canadian Pacific Railway | The Canadian Pacific Railway (French: Chemin de fer Canadien Pacifique) (reporting marks CP, CPAA, MILW, SOO), also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996), was a Canadian Class I railway incorporated in 1881. The railway was owned by Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001.
Headquartered in Calgary, Alberta, the railway owned approximately 20,100 kilometres (12,500 mi) of track in seven provinces of Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also served Minneapolis–St. Paul, Milwaukee, Detroit, Chicago, and Albany, New York, in the United States.
The railway was first built between eastern Canada and British Columbia between 1881 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a commitment extended to British Columbia when it entered Confederation in 1871; the CPR was Canada's first transcontinental railway. Primarily a freight railway, the CPR was for decades the only practical means of long-distance passenger transport in most regions of Canada and was instrumental in the settlement and development of Western Canada. The CPR became one of the largest and most powerful companies in Canada, a position it held as late as 1975.
The company acquired two American lines in 2009: the Dakota, Minnesota and Eastern Railroad (DM&E) and the Iowa, Chicago and Eastern Railroad (IC&E). The trackage of the IC&E was at one time part of CP subsidiary Soo Line and predecessor line The Milwaukee Road. The combined DM&E/IC&E system spanned North Dakota, South Dakota, Minnesota, Wisconsin, Nebraska and Iowa, with two lines stretching into Kansas City, Missouri, and Chicago, Illinois. Also, the company owns the Indiana Harbor Belt Railroad, a Hammond, Indiana-based terminal railroad along with Conrail Shared Assets Operations. CP's ownership of that railroad traces back to the Soo Line's ownership, inherited from the Milwaukee Road.
The CPR is publicly traded on both the Toronto Stock Exchange and the New York Stock Exchange under the ticker CP. Its U.S. headquarters are in Minneapolis. As of March 30, 2023, the largest shareholder of Canadian Pacific stock exchange is TCI Fund Management Limited, a London-based hedge fund that owns 6% of the company.
CP purchased the Kansas City Southern Railway in December 2021 for US$31 billion. On April 14, 2023, the railroads merged to form CPKC, the first and only railroad to directly serve Canada, Mexico and the United States.
The creation of the Canadian Pacific Railway was originally undertaken as the National Dream by the Conservative government of John A. Macdonald, together with mining magnate Alexander Tilloch Galt. As a condition for joining the Canadian Confederation, British Columbia had insisted on a transport link to the East, with the rest of the Confederation. In 1873, Macdonald, among other high-ranking politicians, bribed in the Pacific Scandal, granted contracts to the Canada Pacific Railway Company, which was unrelated to the current company, as opposed to the Inter-Ocean Railway Company, which was thought to have connections to the Northern Pacific Railway Company in the United States. After this scandal, the Conservatives were removed from power, and Alexander Mackenzie, the new Liberal prime minister, ordered construction of the railway under the supervision of the Department of Public Works. Macdonald would later return as prime minister and adopt a more aggressive construction policy; bonds were floated in London and caleld for tenders to complete sections of the railway in British Columbia. American contractor Andrew Onderdonk was selected, and his men began construction on 15 May 1880.
In October 1880, a new consortium signed a contract with the Macdonald government, agreeing to build the railway for $25 million in credit and 25 million acres (100,000 km) of land. In addition, the government defrayed surveying costs and excempted the railway from property taxes for 20 years.
A beaver was chosen as the railway's logo in honour of Donald Smith, 1st Baron Strathcona and Mount Royal, who had risen from factor to governor of the Hudson's Bay Company over a lengthy career in the beaver fur trade.
Building the railway took over four years. The Canadian Pacific Railway began its westward expansion from Bonfield, Ontario, where the first spike was driven into a sunken railway tie. That was the point where the Canada Central Railway (CCR) extension ended. The CCR started in Brockville and extended to Pembroke. It then followed a westward route along the [[Ottawa River] and continued to Mattawa at the confluence of the Mattawa and Ottawa rivers. It then proceeded to Bonfield.
It was presumed that the railway would travel through the rich "Fertile Belt" of the North Saskatchewan River Valley and cross the Rocky Mountains via the Yellowhead Pass. However, a more southerly route across the arid Palliser's Triangle in Saskatchewan and via Kicking Horse Pass and down the Field Hill to the Rocky Mountain Trench was chosen.
In 1881, construction progressed at a pace too slow for the railway's officials who, in 1882, hired the renowned railway executive William Cornelius Van Horne to oversee construction. Van Horne stated that he would have 800 km (500 mi) of main line built in 1882. Floods delayed the start of the construction season, but over 672 km (418 mi) of main line, as well as sidings and branch lines, were built that year. The Thunder Bay branch (west from Fort William) was completed in June 1882 by the Department of Railways and Canals and turned over to the company in May 1883. By the end of 1883, the railway had reached the Rocky Mountains, just eight kilometres (five miles) east of Kicking Horse Pass.
Many thousands of navvies worked on the railway. Many were European immigrants. In British Columbia, government contractors eventually hired 17,000 workers from China, known as "coolies". After 21⁄2 months of hard labour, they could net as little as $16. Chinese labourers in British Columbia made only between 75 cents and $1.25 a day, paid in rice mats, and not including expenses, leaving barely anything to send home. They did the most dangerous construction jobs, such as working with explosives to clear tunnels through rock. The exact number of Chinese workers who died is unknown, but historians estimate the number is between 600 and 800. According to Historica Canada, it is believed that for every mile of track laid in British Columbia, there is one dead Chinese worker..
By 1883, railway construction was progressing rapidly, but the CPR was in danger of running out of funds. In response, on 31 January 1884, the government passed the Railway Relief Bill, providing a further $22.5 million in loans to the CPR. The bill received royal assent on 6 March 1884.
In March 1885, the North-West Rebellion broke out in the District of Saskatchewan. Van Horne, in Ottawa at the time, suggested to the government that the CPR could transport troops to Qu'Appelle, Assiniboia, in 10 days. Some sections of track were incomplete or had not been used before, but the trip to Winnipeg was made in nine days and the rebellion quickly suppressed. Controversially, the government subsequently reorganized the CPR's debt and provided a further $5 million loan. This money was desperately needed by the CPR. Even with Van Horne's support with moving troops to Qu'Appelle, the government still delayed in giving its support to CPR, due to Macdonald pressuring George Stephen for additional benefits.
On 7 November 1885, the last spike was driven at Craigellachie, British Columbia. Four days earlier, the last spike of the Lake Superior section was driven in just west of Jackfish, Ontario. While the railway was completed four years after the original 1881 deadline, it was completed more than five years ahead of the new date of 1891 that Macdonald gave in 1881.
In Eastern Canada, the CPR had created a network of lines reaching from Quebec City to St. Thomas, Ontario, by 1885 – mainly by buying the Quebec, Montreal, Ottawa & Occidental Railway from the Quebec government and by creating a new railway company, the Ontario and Quebec Railway (O&Q). It also launched a fleet of Great Lakes ships to link its terminals. Through the O&Q, the CPR had effected purchases and long-term leases of several railways, and built a line between Perth, Ontario, and Toronto (completed on 5 May 1884) to connect these acquisitions. The CPR obtained a 999-year lease on the O&Q on 4 January 1884. In 1895, it acquired a minority interest in the Toronto, Hamilton and Buffalo Railway, giving it a link to New York and the Northeast United States.
The last spike in the CPR was driven on 7 November 1885, by one of its directors, Donald Smith.
The first transcontinental passenger train departed from Montreal's Dalhousie Station, located at Berri Street and Notre Dame Street at 8 pm on 28 June 1886, and arrived at Port Moody at noon on 4 July. This train consisted of two baggage cars, a mail car, one second-class coach, two immigrant sleepers, two first-class coaches, two sleeping cars and a diner (several dining cars were used throughout the journey, as they were removed from the train during the night, with another one added the next morning).
By that time, however, the CPR had decided to move its western terminus from Port Moody to Granville, which was renamed "Vancouver" later that year. The first official train destined for Vancouver arrived on 23 May 1887, although the line had already been in use for three months. The CPR quickly became profitable, and all loans from the federal government were repaid years ahead of time. In 1888, a branch line was opened between Sudbury and Sault Ste. Marie where the CPR connected with the American railway system and its own steamships. That same year, work was started on a line from London, Ontario, to the Canada–US border at Windsor, Ontario. That line opened on 12 June 1890.
The CPR also leased the New Brunswick Railway in 1891 for 991 years, and built the International Railway of Maine, connecting Montreal with Saint John, New Brunswick, in 1889. The connection with Saint John on the Atlantic coast made the CPR the first truly transcontinental railway company in Canada and permitted trans-Atlantic cargo and passenger services to continue year-round when sea ice in the Gulf of St. Lawrence closed the port of Montreal during the winter months. By 1896, competition with the Great Northern Railway for traffic in southern British Columbia forced the CPR to construct a second line across the province, south of the original line. Van Horne, now president of the CPR, asked for government aid, and the government agreed to provide around $3.6 million to construct a railway from Lethbridge, Alberta, through Crowsnest Pass to the south shore of Kootenay Lake, in exchange for the CPR agreeing to reduce freight rates in perpetuity for key commodities shipped in Western Canada.
The controversial Crowsnest Pass Agreement effectively locked the eastbound rate on grain products and westbound rates on certain "settlers' effects" at the 1897 level. Although temporarily suspended during the First World War, it was not until 1983 that the "Crow Rate" was permanently replaced by the Western Grain Transportation Act, which allowed the gradual increase of grain shipping prices. The Crowsnest Pass line opened on 18 June 1898, and followed a complicated route through the maze of valleys and passes in southern British Columbia, rejoining the original mainline at Hope after crossing the Cascade Mountains via Coquihalla Pass.
The Southern Mainline, generally known as the Kettle Valley Railway in British Columbia, was built in response to the booming mining and smelting economy in southern British Columbia, and the tendency of the local geography to encourage and enable easier access from neighbouring US states than from Vancouver or the rest of Canada, which was viewed to be as much of a threat to national security as it was to the province's control of its own resources. The local passenger service was re-routed to this new southerly line, which connected numerous emergent small cities across the region. Independent railways and subsidiaries that were eventually merged into the CPR in connection with this route were the Shuswap and Okanagan Railway, the Kaslo and Slocan Railway, the Columbia and Kootenay Railway, the Columbia and Western Railway and various others.
The CPR had built a railway that operated mostly in the wilderness. The usefulness of the prairies was questionable in the minds of many. The thinking prevailed that the prairies had great potential. Under the initial contract with the Canadian government to build the railway, the CPR was granted 100,000 square kilometres (25 million acres). Proving already to be a very resourceful organization, Canadian Pacific began an intense campaign to bring immigrants to Canada. Canadian Pacific agents operated in many overseas locations. Immigrants were often sold a package that included passage on a CP ship, travel on a CP train and land sold by the CP railway. Land was priced at $2.50 an acre and up but required cultivation. To transport immigrants, Canadian Pacific developed a fleet of over a thousand Colonist cars, low-budget sleeper cars designed to transport immigrant families from eastern Canadian seaports to the west.
During the first decade of the 20th century, the CPR continued to build more lines. In 1908, the CPR opened a line connecting Toronto with Sudbury. Previously, westbound traffic originating in southern Ontario took a circuitous route through eastern Ontario. Several operational improvements were also made to the railway in Western Canada. In 1909 the CPR completed two significant engineering accomplishments. The most significant was the replacement of the Big Hill, which had become a major bottleneck in the CPR's main line, with the Spiral Tunnels, reducing the grade to 2.2 percent from 4.5 percent. The Spiral Tunnels opened in August. In April 1908, the CPR started work to replace the Old Calgary-Edmonton Rail Bridge across the Red Deer River with a new standard steel bridge that was completed by March 1909.
On 3 November 1909, the Lethbridge Viaduct over the Oldman River valley at Lethbridge, Alberta, was opened. It is 1,624 metres (5,328 feet) long and, at its maximum, 96 metres (315 feet) high, making it one of the longest railway bridges in Canada. In 1916, the CPR replaced its line through Rogers Pass, which was prone to avalanches (the most serious of which killed 62 men in 1910) with the Connaught Tunnel, an eight-kilometre-long (5-mile) tunnel under Mount Macdonald that was, at the time of its opening, the longest railway tunnel in the Western Hemisphere.
On 21 January 1910, a passenger train derailed on the CPR line at the Spanish River bridge at Nairn, Ontario (near Sudbury), killing at least 43.
The CPR acquired several smaller railways via long-term leases in 1912. On 3 January 1912, the CPR acquired the Dominion Atlantic Railway, a railway that ran in western Nova Scotia. This acquisition gave the CPR a connection to Halifax, a significant port on the Atlantic Ocean. The Dominion Atlantic was isolated from the rest of the CPR network and used the CNR to facilitate interchange; the DAR also operated ferry services across the Bay of Fundy for passengers and cargo (but not rail cars) from the port of Digby, Nova Scotia, to the CPR at Saint John, New Brunswick. DAR steamships also provided connections for passengers and cargo between Yarmouth, Boston and New York. On 1 July 1912, the CPR acquired the Esquimalt and Nanaimo Railway, a railway on Vancouver Island that connected to the CPR using a railcar ferry. The CPR acquired the Quebec Central Railway on 14 December 1912.
During the late 19th century, the railway undertook an ambitious programme of hotel construction, building Glacier House in Glacier National Park, Mount Stephen House at Field, British Columbia, the Château Frontenac in Quebec City and the Banff Springs Hotel. By then, the CPR had competition from three other transcontinental lines, all of them money-losers. In 1919, these lines were consolidated, along with the track of the old Intercolonial Railway and its spurs, into the government-owned Canadian National Railways. The CPR suffered its greatest loss of life when one of its steamships, the Empress of Ireland, sank after a collision with the Norwegian collier SS Storstad. On 29 May 1914, the Empress (operated by the CPR's Canadian Pacific Steamship Company) went down in the St. Lawrence River with the loss of 1,024 lives, of which 840 were passengers.
During the First World War, CPR put the entire resources of the "world's greatest travel system" at the disposal of the British Empire, not only trains and tracks, but also its ships, shops, hotels, telegraphs and, above all, its people. Aiding the war effort meant transporting and billeting troops; building and supplying arms and munitions; arming, lending and selling ships. Fifty-two CPR ships were pressed into service during World War I, carrying more than a million troops and passengers and four million tons of cargo. Twenty seven survived and returned to CPR. CPR also helped the war effort with money and jobs. CPR made loans and guarantees to the Allies of some $100 million. As a lasting tribute, CPR commissioned three statues and 23 memorial tablets to commemorate the efforts of those who fought and those who died in the war. After the war, the Federal government created Canadian National Railways (CNR, later CN) out of several bankrupt railways that fell into government hands during and after the war. CNR would become the main competitor to the CPR in Canada. In 1923, Henry Worth Thornton replaced David Blyth Hanna becoming the second president of the CNR, and his competition spurred Edward Wentworth Beatty, the first Canadian-born president of the CPR, to action. During this time the railway land grants were formalized.
The Great Depression, which lasted from 1929 until 1939, hit many companies heavily. While the CPR was affected, it was not affected to the extent of its rival CNR because it, unlike the CNR, was debt-free. The CPR scaled back on some of its passenger and freight services and stopped issuing dividends to its shareholders after 1932. Hard times led to the creation of new political parties such as the Social Credit movement and the Cooperative Commonwealth Federation, as well as popular protest in the form of the On-to-Ottawa Trek.
One highlight of the late 1930s, both for the railway and for Canada, was the visit of King George VI and Queen Elizabeth during their 1939 royal tour of Canada, the first time that the reigning monarch had visited the country. The CPR and the CNR shared the honours of pulling the royal train across the country, with the CPR undertaking the westbound journey from Quebec City to Vancouver. Later that year, the Second World War began. As it had done in World War I, the CPR devoted much of its resources to the war effort. It retooled its Angus Shops in Montreal to produce Valentine tanks and other armoured vehicles, and transported troops and resources across the country. Additionally, 22 of the CPR's ships went to war, 12 of which were sunk.
After the Second World War, the transportation industry in Canada changed. Where railways had previously provided almost universal freight and passenger services, cars, trucks and airplanes started to take traffic away from railways. This naturally helped the CPR's air and trucking operations, and the railway's freight operations continued to thrive hauling resource traffic and bulk commodities. However, passenger trains quickly became unprofitable. During the 1950s, the railway introduced new innovations in passenger service. In 1955, it introduced The Canadian, a new luxury transcontinental train. However, in the 1960s, the company started to pull out of passenger services, ending services on many of its branch lines. It also discontinued its secondary transcontinental train The Dominion in 1966, and in 1970, unsuccessfully applied to discontinue The Canadian. For the next eight years, it continued to apply to discontinue the service, and service on The Canadian declined markedly. On 29 October 1978, CP Rail transferred its passenger services to Via Rail, a new federal Crown corporation that is responsible for managing all intercity passenger service formerly handled by both CP Rail and CN. Via eventually took almost all of its passenger trains, including The Canadian, off CP's lines.
In 1968, as part of a corporate reorganization, each of the major operations, including its rail operations, were organized as separate subsidiaries. The name of the railway was changed to CP Rail, and the parent company changed its name to Canadian Pacific Limited in 1971. Its air, express, telecommunications, hotel and real estate holdings were spun off, and ownership of all of the companies transferred to Canadian Pacific Investments. The slogan was: "TO THE FOUR CORNERS OF THE WORLD" The company discarded its beaver logo, adopting the new Multimark (which, when mirrored by an adjacent "multi-mark" creates a diamond appearance on a globe) that was used – with a different colour background – for each of its operations.
On 10 November 1979, a derailment of a hazardous materials train in Mississauga, Ontario, led to the evacuation of 200,000 people; there were no fatalities. Mississauga Mayor Hazel McCallion threatened to sue Canadian Pacific for the derailment. Part of the compromise was to accept GO Transit commuter rail service along the Galt Subdivision corridor up to Milton, Ontario. Limited trains ran along the Milton line on weekdays only. Expansions to Cambridge, Ontario may be coming in the future.
In 1984, CP Rail commenced construction of the Mount Macdonald Tunnel to augment the Connaught Tunnel under the Selkirk Mountains. The first revenue train passed through the tunnel in 1988. At 14.7 km (nine miles), it is the longest tunnel in the Americas. During the 1980s, the Soo Line Railroad, in which CP Rail still owned a controlling interest, underwent several changes. It acquired the Minneapolis, Northfield and Southern Railway in 1982. Then on 21 February 1985, the Soo Line obtained a controlling interest in the bankrupt Milwaukee Road, merging it into its system on 1 January 1986. Also in 1980, Canadian Pacific bought out the controlling interests of the Toronto, Hamilton and Buffalo Railway (TH&B) from Conrail and molded it into the Canadian Pacific System, dissolving the TH&B's name from the books in 1985. In 1987, most of CPR's trackage in the Great Lakes region, including much of the original Soo Line, were spun off into a new railway, the Wisconsin Central, which was subsequently purchased by CN. Influenced by the Canada-U.S. Free Trade Agreement of 1989, which liberalized trade between the two nations, the CPR's expansion continued during the early 1990s: CP Rail gained full control of the Soo Line in 1990, adding the "System" to the former's name, and bought the Delaware and Hudson Railway in 1991. These two acquisitions gave CP Rail routes to the major American cities of Chicago (via the Soo Line and Milwaukee Road as part of its historically logical route) and New York City (via the D&H).
During the 1990s, both CP Rail and CN attempted unsuccessfully to buy out the eastern assets of the other, so as to permit further rationalization. In 1996, CP Rail moved its head office from Windsor Station in Montreal to Gulf Canada Square in Calgary and changed its name back to Canadian Pacific Railway.
A new subsidiary company, the St. Lawrence and Hudson Railway, was created to operate its money-losing lines in eastern North America, covering Quebec, Southern and Eastern Ontario, trackage rights to Chicago, Illinois, (on Norfolk Southern lines from Detroit) as well as the Delaware and Hudson Railway in the northeastern United States. However, the new subsidiary, threatened with being sold off and free to innovate, quickly spun off money-losing track to short lines, instituted scheduled freight service, and produced an unexpected turn-around in profitability. On 1 January 2001 the StL&H was formally amalgamated with the CP Rail system.
In 2001, the CPR's parent company, Canadian Pacific Limited, spun off its five subsidiaries, including the CPR, into independent companies. In September 2007, CPR announced it was acquiring the Dakota, Minnesota and Eastern Railroad from London-based Electra Private Equity. The merger was completed as of 31 October 2008.
Canadian Pacific Railway Ltd. trains resumed regular operations on 1 June 2012 after a nine-day strike by some 4,800 locomotive engineers, conductors and traffic controllers who walked off the job on 23 May, stalling Canadian freight traffic and costing the economy an estimated CA$80 million (US$77 million). The strike ended with a government back-to-work bill forcing both sides to come to a binding agreement.
On 6 July 2013, a unit train of crude oil which CP had subcontracted to short-line operator Montreal, Maine and Atlantic Railway derailed in Lac-Mégantic, killing 47. On 14 August 2013, the Quebec government added the CPR, along with lessor World Fuel Services (WFS), to the list of corporate entities from which it seeks reimbursement for the environmental cleanup of the Lac-Mégantic derailment. On 15 July, the press reported that CP would appeal the legal order.
On 12 October 2014 it was reported that Canadian Pacific had tried to enter into a merger with American railway CSX, but was unsuccessful.
In 2015–16 Canadian Pacific sought to merge with American railway Norfolk Southern. and wanted to have a shareholder vote on it. CP ultimately terminated its efforts to merge on 11 April 2016.
On 4 February 2019, a loaded grain train ran away from the siding at Partridge just above the Upper Spiral Tunnel in Kicking Horse Pass. The 112-car grain train with three locomotives derailed into the Kicking Horse River just after the Trans Canada Highway overpass. The three crew members on the lead locomotive were killed. The Canadian Pacific Police Service (CPPS) investigated the fatal derailment. It later came to light that, although Creel said that the RCMP "retain jurisdiction" over the investigation, the RCMP wrote that "it never had jurisdiction because the crash happened on CP property". On 26 January 2020, Canadian current affairs program The Fifth Estate broadcast an episode on the derailment, and the next day the Canadian Transportation Safety Board (TSB) called for the RCMP to investigate as lead investigator Don Crawford said, "There is enough to suspect there's negligence here and it needs to be investigated by the proper authority".
On 4 February 2020, the TSB demoted its lead investigator in the crash probe after his superiors decided these comments were "completely inappropriate". The TSB stated that it "does not share the view of the lead safety investigator". The CPPS say they did a thorough investigation into the actions of the crew, which is now closed and resulted in no charges, while the Alberta Federation of Labour and the Teamsters Canada Rail Conference called for an independent police probe.
On 20 November 2019, it was announced that Canadian Pacific would purchase the Central Maine and Quebec Railway from Fortress Transportation and Infrastructure Investors. The line had had a series of different owners since being spun off of the Canadian Pacific in 1995. The first operator was the Canadian American Railroad a division of Iron Road Railways. In 2002 the Montreal, Maine & Atlantic took over operations after CDAC declared bankruptcy. The Central, Maine and Quebec Railway started operations in 2014 after the MMA declared bankruptcy due to the Lac-Mégantic derailment. On this new acquisition, CP CEO Keith Creel remarked that this gives CP a true coast-to-coast network across Canada and an increased presence in New England. On June 4, 2020; Canadian Pacific bought the Central Maine and Quebec.
On March 21, 2021, CP announced that it was planning to purchase the Kansas City Southern Railway (KCS) for US$29 billion. The US Surface Transportation Board (STB) would first have to approve the purchase, which was expected to be completed by the middle of 2022.
However, a competing cash and stock offer was later made by Canadian National Railway (CN) on April 20 at $33.7 billion. On May 13, KCS announced that they planned to accept the merger offer from CN, but would give CP until May 21 to come up with a higher bid. On May 21, KCS and CN agreed to a merger. However, CN's merger attempt was blocked by a STB ruling in August that the company could not use a voting trust to assume control of KCS, due to concerns about potentially reduced competition in the railroad industry.
On September 12, KCS accepted a new $31 billion offer from CP. Though CP's offer was lower than the offer made by CN, the STB permitted CP to use a voting trust to take control of KCS. The voting trust allowed CP to become the beneficial owner of KCS in December, but the two railroads operated independently until receiving approval for a merger of operations from the STB. That approval came on March 15, 2023, which permitted the railroads to merge as soon as April 14. Post merger, the combined railroad would rebrand under a new name: Canadian Pacific Kansas City (CPKC). On April 14, 2023, CP and the Kansas City Southern Railway merged into one, forming CPKC.
Over half of CP's freight traffic is in grain (24% of 2016 freight revenue), intermodal freight (22%), and coal (10%) and the vast majority of its profits are made in western Canada. A major shift in trade from the Atlantic to the Pacific has caused serious drops in CPR's wheat shipments through Thunder Bay. It also ships chemicals and plastics (12% of 2016 revenue), automotive parts and assembled automobiles (6%), potash (6%), sulphur and other fertilizers (5%), forest products (5%), and various other products (11%). The busiest part of its railway network is along its main line between Calgary and Vancouver. Since 1970, coal has become a major commodity hauled by CPR. Coal is shipped in unit trains from coal mines in the mountains, most notably Sparwood, British Columbia, to terminals at Roberts Bank and North Vancouver, from where it is then shipped to Japan.
Grain is hauled by the CPR from the prairies to ports at Thunder Bay (the former cities of Fort William and Port Arthur), Quebec City and Vancouver, where it is then shipped overseas. The traditional winter export port was Saint John, New Brunswick, when ice closed the St. Lawrence River. Grain has always been a significant commodity hauled by the CPR; between 1905 and 1909, the CPR double-tracked its section of track between Fort William, Ontario (part of present-day Thunder Bay) and Winnipeg to facilitate grain shipments. For several decades this was the only long stretch of double-track mainline outside of urban areas on the CPR. Today, though the Thunder Bay-Winnipeg section is now single tracked, the CPR still has two long distance double track lines serving rural areas, including a 121-kilometre (75 mi) stretch between Kent, British Columbia, and Vancouver which follows the Fraser River into the Coast Mountains, as well as the Canadian Pacific Winchester Sub, a 160-kilometre (100 mi) stretch of double track mainline which runs from Smiths Falls, Ontario, through downtown Montreal which runs through many rural farming communities. However, CPR is in the midst of partially dismantling the stretch of double track mainline on the Winchester Sub. There are also various long stretches of double track between Golden and Kamloops, British Columbia, and portions of the original Winnipeg-Thunder Bay double track (such as 30 kilometres (20 mi) through Kenora and Keewatin, Ontario) are still double track.
The train was the primary mode of long-distance transport in Canada until the 1960s. Among the many types of people who rode CPR trains were new immigrants heading for the prairies, military troops (especially during the two world wars) and upper class tourists. It also custom-built many of its passenger cars at its CPR Angus Shops to be able to meet the demands of the upper class.
The CPR also had a line of Great Lakes ships integrated into its transcontinental service. From 1885 until 1912, these ships linked Owen Sound on Georgian Bay to Fort William. Following a major fire in December 1911 that destroyed the grain elevator, operations were relocated to a new, larger port created by the CPR at Port McNicoll opening in May 1912. Five ships allowed daily service, and included the S.S. Assiniboia and S.S. Keewatin built in 1908 which remained in use until the end of service. Travellers went by train from Toronto to that Georgian Bay port, then travelled by ship to link with another train at the Lakehead. After World War II, the trains and ships carried automobiles as well as passengers. This service featured what was to become the last boat train in North America. The Steam Boat was a fast, direct connecting train between Toronto and Port McNicoll. The passenger service was discontinued at the end of season in 1965 with one ship, the Keewatin, carrying on in freight service for two more years. It later became a marine museum at Douglas, Michigan, in the United States, before returning to its original homeport of Port McNicoll, Canada in 2013.
After the Second World War, passenger traffic declined as automobiles and airplanes became more common, but the CPR continued to innovate in an attempt to keep passenger numbers up. Beginning 9 November 1953, the CPR introduced Budd Rail Diesel Cars (RDCs) on many of its lines. Officially called "Dayliners" by the CPR, they were always referred to as Budd Cars by employees. Greatly reduced travel times and reduced costs resulted, which saved service on many lines for a number of years. The CPR went on to acquire the second largest fleet of RDCs totalling 52 cars. Only the Boston and Maine Railroad had more. This CPR fleet also included the rare model RDC-4 (which consisted of a mail section at one end and a baggage section at the other end with no formal passenger section). On 24 April 1955, the CPR introduced a new luxury transcontinental passenger train, The Canadian. The train provided service between Vancouver and Toronto or Montreal (east of Sudbury; the train was in two sections). The train, which operated on an expedited schedule, was pulled by diesel locomotives, and used new, streamlined, stainless steel rolling stock. This service was initially heavily promoted by the company and many images of the train, especially as it traversed the Canadian Rockies, were captured by CPR's official photographer Nicholas Morant. Featured in numerous advertising promotions worldwide, several such images have gained iconic status.
Starting in the 1960s, however, the railway started to discontinue much of its passenger service, particularly on its branch lines. For example, passenger service ended on its line through southern British Columbia and Crowsnest Pass in January 1964, and on its Quebec Central in April 1967, and the transcontinental train The Dominion was dropped in January 1966. On 29 October 1978, CP Rail transferred its passenger services to Via Rail, a new federal Crown corporation that was now responsible for intercity passenger services in Canada. Canadian Prime Minister Brian Mulroney presided over major cuts in Via Rail service on 15 January 1990. This ended service by The Canadian over CPR rails, and the train was rerouted on the former Super Continental route via Canadian National without a change of name. Where both trains had been daily prior to the 15 January 1990 cuts, the surviving Canadian was only a three-times-weekly operation. In October 2012, The Canadian was reduced to twice-weekly for the six-month off-season period, and currently operates three-times-weekly for only six months a year. In addition to inter-city passenger services, the CPR also provided commuter rail services in Montreal. CP Rail introduced Canada's first bi-level passenger cars here in 1970. On 1 October 1982, the Montreal Urban Community Transit Commission (STCUM) assumed responsibility for the commuter services previously provided by CP Rail. It continues under the Metropolitan Transportation Agency (AMT).
Canadian Pacific Railway currently operates two commuter services under contract. GO Transit contracts CPR to operate six return trips between Milton and central Toronto in Ontario. In Montreal, 59 daily commuter trains run on CPR lines from Lucien-L'Allier Station to Candiac, Hudson and Blainville–Saint-Jérôme on behalf of the AMT. CP no longer operates Vancouver's West Coast Express on behalf of TransLink, a regional transit authority. Bombardier Transportation assumed control of train operations on 5 May 2014. Although CP Rail no longer owns the track nor operates the commuter trains, it handles dispatching of Metra trains on the Milwaukee District/North and Milwaukee District/West Lines in Chicago, on which the CP also provides freight service via trackage rights.
Sleeping cars were operated by a separate department of the railway that included the dining and parlour cars and aptly named as the Sleeping, Dining and Parlour Car Department. The CPR decided from the very beginning that it would operate its own sleeping cars, unlike railways in the United States that depended upon independent companies that specialized in providing cars and porters, including building the cars themselves. Pullman was long a famous name in this regard; its Pullman porters were legendary. Other early companies included the Wagner Palace Car Company. Bigger-sized berths and more comfortable surroundings were built by order of the CPR's General Manager, William Van Horne, who was a large man himself. Providing and operating their own cars allowed better control of the service provided as well as keeping all of the revenue received, although dining-car services were never profitable. But railway managers realized that those who could afford to travel great distances expected such facilities, and their favourable opinion would bode well to attracting others to Canada and the CPR's trains.
W. C. Van Horne decided from the very beginning that the CPR would retain as much revenue from its various operations as it could. This translated into keeping express, telegraph, sleeping car and other lines of business for themselves, creating separate departments or companies as necessary. This was necessary as the fledgling railway would need all the income it could get, and in addition, he saw some of these ancillary operations such as express and telegraph as being quite profitable. Others such as sleeping and dining cars were kept in order to provide better control over the quality of service being provided to passengers. Hotels were likewise crucial to the CPR's growth by attracting travellers.
Dominion Express Company was formed independently in 1873 before the CPR itself, although train service did not begin until the summer of 1882 at which time it operated over some 500 kilometres (300 mi) of track from Rat Portage (Kenora) Ontario west to Winnipeg, Manitoba. It was soon absorbed into the CPR and expanded everywhere the CPR went. It was renamed Canadian Express Company on 1 September 1926, and the headquarters moved from Winnipeg, to Toronto. It was operated as a separate company with the railway charging them to haul express cars on trains. Express was handled in separate cars, some with employees on board, on the headend of passenger trains to provide a fast scheduled service for which higher rates could be charged than for LCL (Less than Carload Lot), small shipments of freight which were subject to delay. Aside from all sorts of small shipments for all kinds of businesses such products as cream, butter, poultry and eggs were handled along with fresh flowers, fish and other sea foods some handled in separate refrigerated cars. Horses and livestock along with birds and small animals including prize cattle for exhibition were carried often in special horse cars that had facilities for grooms to ride with their animals.
Automobiles for individuals were also handled by express in closed boxcars. Gold and silver bullion as well as cash were carried in large amounts between the mint and banks and Express messengers were armed for security. Small business money shipments and valuables such as jewellery were routinely handled in small packets. Money orders and travellers' cheques were an important part of the express company's business and were used worldwide in the years before credit cards. Canadian Express Cartage Department was formed in March 1937 to handle pickup and delivery of most express shipments including less-than-carload freight. Their trucks were painted Killarney (dark) green while regular express company vehicles were painted bright red. Express routes using highway trucks beginning in November 1945 in southern Ontario and Alberta co-ordinated railway and highway service expanded service to better serve smaller locations especially on branchlines. Trucking operations would go on to expand across Canada making it an important transport provider for small shipments. Deregulation in the 1980s, however, changed everything and trucking services were ended after many attempts to change with the times.
Between the 1890s and 1933, the CPR transported raw silk from Vancouver, where it had been shipped from the Orient, to silk mills in New York and New Jersey. A silk train could carry several million dollars' worth of silk, so they had their own armed guards. To avoid train robberies and so minimize insurance costs, they travelled quickly and stopped only to change locomotives and crews, which was often done in under five minutes. The silk trains had superior rights over all other trains; even passenger trains (including the Royal Train of 1939) would be put in sidings to make the silk trains' trip faster. At the end of World War II, the invention of nylon made silk less valuable, so the silk trains died out.
Funeral trains would carry the remains of important people, such as prime ministers. As the train would pass, mourners would be at certain spots to show respect. Two of the CPR's funeral trains are particularly well-known. On 10 June 1891, the funeral train of Prime Minister Sir John A. Macdonald ran from Ottawa to Kingston, Ontario. The train consisted of five heavily draped passenger cars and was pulled by 4-4-0 No. 283. On 14 September 1915, the funeral train of former CPR president Sir William Cornelius Van Horne ran from Montreal to Joliet, Illinois, pulled by 4-6-2 No. 2213.
The CPR ran a number of trains that transported members of the Canadian royal family when they toured the country, taking them through Canada's scenery, forests, and small towns, and enabling people to see and greet them. Their trains were elegantly decorated; some had amenities such as a post office and barber shop. The CPR's most notable royal train was in 1939, when the CPR and the CNR had the honour of carrying King George VI and Queen Elizabeth during their coast-to-coast-and-back tour of Canada; one company took the royal couple from Quebec City to Vancouver and the other company took them on the return journey to Halifax. This was the first tour of Canada by its reigning monarch. The steam locomotives used to pull the train included CPR 2850, a Hudson (4-6-4) built by Montreal Locomotive Works in 1938, CNR 6400, a U-4-a Northern (4-8-4) and CNR 6028 a U-1-b Mountain (4-8-2) type. They were specially painted royal blue, with the exception of CNR 6028 which was not painted, with silver trim as was the entire train. The locomotives ran 5,189 km (3,224 mi) across Canada, through 25 changes of crew, without engine failure. The King, somewhat of a railbuff, rode in the cab when possible. After the tour, King George gave the CPR permission to use the term "Royal Hudson" for the CPR locomotives and to display Royal Crowns on their running boards. This applied only to the semi-streamlined locomotives (2820–2864), not the "standard" Hudsons (2800–2819).
CPR provided the rolling stock for the Better Farming Train which toured rural Saskatchewan between 1914 and 1922 to promote the latest information on agricultural research. It was staffed by the University of Saskatchewan and operating expenses were covered by the Department of Agriculture.
Between 1927 and the early 1950s, the CPR ran a school car to reach children who lived in Northern Ontario, far from schools. A teacher would travel in a specially designed car to remote areas and would stay to teach in one area for two to three days, then leave for another area. Each car had a blackboard and a few sets of chairs and desks. They also contained miniature libraries and accommodation for the teacher.
Major shooting for the 1976 film Silver Streak, a fictional comedy tale of a murder-ridden train trip from Los Angeles to Chicago, was done on the CPR, mainly in the Alberta area with station footage at Toronto's Union Station. The train set was so lightly disguised as the fictional "AMRoad" that the locomotives and cars still carried their original names and numbers, along with the easily identifiable CP Rail red-striped paint scheme. Most of the cars are still in revenue service on Via Rail Canada; the lead locomotive (CP 4070) and the second unit (CP 4067) were sold to Via Rail and CTCUM respectively.
Starting in 1999, CP runs a Holiday Train along its main line during the months of November and December. The Holiday Train celebrates the holiday season and collects donations for community food banks and hunger issues. The Holiday Train also provides publicity for CP and a few of its customers. Each train has a box car stage for entertainers who are travelling along with the train.
The train is a freight train, but also pulls vintage passenger cars which are used as lodging/transportation for the crew and entertainers. Only entertainers and CP employees are allowed to board the train aside from a coach car that takes employees and their families from one stop to the next. All donations collected in a community remain in that community for distribution.
There are two Holiday Trains that cover 150 stops in Canada and the United States Northeast and Midwest. Each train is roughly 1,000 feet (300 m) in length with brightly decorated railway cars, including a modified box car that has been turned into a travelling stage for performers. They are each decorated with hundred of thousands of LED Christmas lights. In 2013 to celebrate the program's 15th year, three signature events were held in Hamilton, Ontario, Calgary, Alberta, and Cottage Grove, Minnesota, to further raise awareness for hunger issues.
The trains feature different entertainers each year; in 2016, one train featured Dallas Smith and the Odds, while the other featured Colin James and Kelly Prescott. After its 20th anniversary tour in 2018, which hosted Terri Clark, Sam Roberts Band, The Trews and Willy Porter, the tour reported to have raised more than CA$15.8 million and collected more than 4.5 million pounds (2,000 t) of food since 1999.
On 7 June 2000, the CPR inaugurated the Royal Canadian Pacific, a luxury excursion service that operates between the months of June and September. It operates along a 1,050 km (650 mi) route from Calgary, through the Columbia Valley in British Columbia, and returning to Calgary via Crowsnest Pass. The trip takes six days and five nights. The train consists of up to eight luxury passenger cars built between 1916 and 1931 and is powered by first-generation diesel locomotives.
In 1998, the CPR repatriated one of its former passenger steam locomotives that had been on static display in the United States following its sale in January 1964, long after the close of the steam era. CPR Hudson 2816 was re-designated Empress 2816 following a 30-month restoration that cost in excess of $1 million. It was subsequently returned to service to promote public relations. It has operated across much of the CPR system, including lines in the U.S. and been used for various charitable purposes; 100% of the money raised goes to the nationwide charity Breakfast for Learning — the CPR bears all of the expenses associated with the operation of the train. 2816 is the subject of Rocky Mountain Express, a 2011 IMAX film which follows the locomotive on an eastbound journey beginning in Vancouver, and which tells the story of the building of the CPR. 2816 has been stored indefinitely since 2012 after CEO E. Hunter Harrison discontinued the steam program.
The locomotive was fired up on November 13, 2020, for a steam test and moved around the Ogden campus yard. At the time, CP only had plans to utilize the locomotive for a special Holiday Train at Home broadcast, after which it was put in storage. However, in mid-2021, CEO Keith Creel announced intentions to bring 2816 back to full operational status, for a tour from their Calgary headquarters to Mexico City, if the merger with Kansas City Southern Railway is approved by the Surface Transportation Board in the United States. Work on the needed overhaul began in earnest in late 2021 for a planned date in 2023.
In 2008, Canadian Pacific partnered with the 2010 Olympic and Paralympic Winter Games to present a "Spirit Train" tour that featured Olympic-themed events at various stops. Colin James was a headline entertainer. Several stops were met by protesters who argued that the games were slated to take place on stolen indigenous land.
In 2017, CP ran the CP Canada 150 Train from Port Moody to Ottawa to celebrate Canada's 150th year since Confederation. The train stopped in 13 cities along its 3-week summer tour, offering a free block party and concert from Dean Brody, Kelly Prescott and Dallas Arcand. The heritage train drew out thousands to sign the special "Spirit of Tomorrow" car, where children were invited to write their wishes for the future of Canada and send them to Ottawa. Prime Minister Justin Trudeau and daughter Ella-Grace Trudeau also visited the train and rode it from Revelstoke to Calgary.
Historically, Canadian Pacific operated several non-railway businesses. In 1971, these businesses were split off into the separate company Canadian Pacific Limited, and in 2001, that company was further split into five companies. CP no longer provides any of these services.
The original charter of the CPR granted in 1881 provided for the right to create an electric telegraph and telephone service including charging for it. The telephone had barely been invented but telegraph was well established as a means of communicating quickly across great distances. Being allowed to sell this service meant the railway could offset the costs of constructing and maintaining a pole line along its tracks across vast distances for its own purposes which were largely for dispatching trains. It began doing so in 1882 as the separate Telegraph Department. It would go on to provide a link between the cables under the Atlantic and Pacific oceans when they were completed. Before the CPR line, messages to the west could be sent only via the United States.
Paid for by the word, the telegram was an expensive way to send messages, but they were vital to businesses. An individual receiving a personal telegram was seen as being someone important except for those that transmitted sorrow in the form of death notices. Messengers on bicycles delivered telegrams and picked up a reply in cities. In smaller locations, the local railway station agent would handle this on a commission basis. To speed things, at the local end messages would first be telephoned. In 1931, it became the Communications Department in recognition of the expanding services provided which included telephones lines, news wire, ticker quotations for capital stocks and eventually teleprinters. All were faster than mail and very important to business and the public alike for many decades before mobile phones and computers came along. It was the coming of these newer technologies especially cellular telephones that eventually resulted in the demise of these services even after formation in 1967 of CN-CP Telecommunications in an effort to effect efficiencies through consolidation rather than competition. Deregulation in the 1980s, brought about mergers and the sale of remaining services and facilities.
On 17 January 1930, the CPR applied for licences to operate radio stations in 11 cities from coast-to-coast for the purpose of organising its own radio network in order to compete with the CNR Radio service. The CNR had built a radio network with the aim of promoting itself as well as entertaining its passengers during their travels. The onset of the Great Depression hurt the CPR's financial plan for a rival project and in April they withdrew their applications for stations in all but Toronto, Montreal and Winnipeg. CPR did not end up pursuing these applications but instead operated a phantom station in Toronto known as "CPRY," with initials standing for "Canadian Pacific Royal York" which operated out of studios at CP's Royal York Hotel and leased time on CFRB and CKGW. A network of affiliates carried the CPR radio network's broadcasts in the first half of the 1930s, but the takeover of CNR's Radio service by the new Canadian Radio Broadcasting Commission removed CPR's need to have a network for competitive reasons and CPR's radio service was discontinued in 1935.
CPR programming included a series of concert broadcasts from Montreal with an orchestra conducted by Douglas Clarke and a series called Concert Orchestra broadcast from the Royal York Hotel featuring conductor Rex Battle, and another series of concerts, this time sponsored by Imperial Oil and featuring conductor Reginald Stewart with a 55-piece orchestra and some of the leading soloists of the day, also performing at the Royal York.
Steamships played an important part in the history of CP from the very earliest days. During construction of the line in British Columbia even before the private CPR took over from the government contractor, ships were used to bring supplies to the construction sites. Similarly, to reach the isolated area of Superior in northern Ontario ships were used to bring in supplies to the construction work. While this work was going on there was already regular passenger service to the West. Trains operated from Toronto to Owen Sound where CPR steamships connected to Fort William where trains once again operated to reach Winnipeg. Before the CPR was completed the only way to reach the West was through the United States via St. Paul and Winnipeg. This Great Lakes steam ship service continued as an alternative route for many years and was always operated by the railway. Canadian Pacific passenger service on the lakes ended in 1965.
In 1884, CPR began purchasing sailing ships as part of a railway supply service on the Great Lakes. Over time, CPR became a railway company with widely organized water transportation auxiliaries including the Great Lakes service, the trans-Pacific service, the Pacific coastal service, the British Columbia lake and river service, the trans-Atlantic service and the Bay of Fundy Ferry service. In the 20th century, the company evolved into an intercontinental railway which operated two transoceanic services which connected Canada with Europe and with Asia. The range of CPR services were aspects of an integrated plan.
Once the railway was completed to British Columbia, the CPR chartered and soon bought their own passenger steamships as a link to the Orient. These sleek steamships were of the latest design and christened with "Empress" names (e. g., RMS Empress of Britain, Empress of Canada, Empress of Australia, and so forth). Travel to and from the Orient and cargo, especially imported tea and silk, were an important source of revenue, aided by Royal Mail contracts. This was an important part of the All-Red Route linking the various parts of the British Empire.
The other ocean part was the Atlantic service to and from the United Kingdom, which began with acquisition of two existing lines, Beaver Line, owned by Elder Dempster and Allan Lines. These two segments became Canadian Pacific Ocean Services (later, Canadian Pacific Steamships) and operated separately from the various lake services operated in Canada, which were considered to be a direct part of the railway's operations. These trans-ocean routes made it possible to travel from Britain to Hong Kong using only the CPR's ships, trains and hotels. CP's 'Empress' ships became world-famous for their luxury and speed. They had a practical role, too, in transporting immigrants from much of Europe to Canada, especially to populate the vast prairies. They also played an important role in both world wars with many of them being lost to enemy action, including Empress of Britain.
There were also a number of rail ferries operated over the years as well including, between Windsor, Ontario, and Detroit from 1890 until 1915. This began with two paddle-wheelers capable of carrying 16 cars. Passenger cars were carried as well as freight. This service ended in 1915 when the CPR made an agreement with the Michigan Central to use their Detroit River tunnel opened in 1910. Pennsylvania-Ontario Transportation Company was formed jointly with the PRR in 1906 to operate a ferry across Lake Erie between Ashtabula, Ohio, and Port Burwell, Ontario, to carry freight cars, mostly of coal, much of it to be burned in CPR steam locomotives. Only one ferry boat was ever operated, Ashtabula, a large vessel which eventually sank in a harbour collision in Ashtabula on 18 September 1958, thus ending the service.
Canadian Pacific Car and Passenger Transfer Company was formed by other interest in 1888 linking the CPR in Prescott, Ontario, and the NYC in Ogdensburg, New York. Service on this route had actually begun very early, in 1854, along with service from Brockville. A bridge built in 1958 ended passenger service however, freight continued until Ogdensburg's dock was destroyed by fire 25 September 1970, thus ending all service. CPC&PTC was never owned by the CPR. Bay of Fundy ferry service was operated for passengers and freight for many years linking Digby, Nova Scotia, and Saint John, New Brunswick. Eventually, after 78 years, with the changing times the scheduled passenger services would all be ended as well as ocean cruises. Cargo would continue on both oceans with a change over to containers. CP was an intermodal pioneer especially on land with road and railway mixing to provide the best service. CP Ships was the final operation, and in the end it too left CP ownership when it was spun off in 2001. CP Ships was merged with Hapag-Lloyd in 2005.
The Canadian Pacific Railway Coast Service (British Columbia Coast Steamships or BCCS) was established when the CPR acquired in 1901 Canadian Pacific Navigation Company (no relation) and its large fleet of ships that served 72 ports along the coast of British Columbia including on Vancouver Island. Service included the Vancouver-Victoria-Seattle Triangle Route, Gulf Islands, Powell River, as well as Vancouver-Alaska service. BCCS operated a fleet of 14 passenger ships made up of a number of Princess ships, pocket versions of the famous oceangoing Empress ships along with a freighter, three tugs and five railway car barges. Popular with tourists, the Princess ships were famous in their own right especially Princess Marguerite (II) which operated from 1949 until 1985 and was the last coastal liner in operation. The best known of the princess ships, however, is Princess Sophia, which sank with no survivors in October 1918 after striking the Vanderbilt Reef in Alaska's Lynn Canal, constituting the largest maritime disaster in the history of the Pacific Northwest. These services continued for many years until changing conditions in the late 1950s brought about their decline and eventual demise at the end of season in 1974. Princess Marguerite was acquired by the province's British Columbia Steamship (1975) Ltd. and continued to operate for a number of years. In 1977 although BCCSS was the legal name, it was rebranded as Coastal Marine Operations (CMO). By 1998 the company was bought by the Washington Marine Group which after purchase was renamed Seaspan Coastal Intermodal Company and then subsequently rebranded in 2011 as Seaspan Ferries Corporation. Passenger service ended in 1981.
The Canadian Pacific Railway Lake and River Service (British Columbia Lake and River Service) developed slowly and in spurts of growth. CP began a long history of service in the Kootenays region of southern British Columbia beginning with the purchase in 1897 of the Columbia and Kootenay Steam Navigation Company which operated a fleet of steamers and barges on the Arrow Lakes and was merged into the CPR as the CPR Lake and River Service which also served the Arrow Lakes and Columbia River, Kootenay Lake and Kootenai River, Lake Okanagan and Skaha Lake, Slocan Lake, Trout Lake, and Shuswap Lake and the Thompson River/Kamloops Lake.
All of these lake operations had one thing in common, the need for shallow draft therefore sternwheelers were the choice of ship. Tugs and barges handled railway equipment including one operation that saw the entire train including the locomotive and caboose go along. These services gradually declined and ended in 1975 except for a freight barge on Slocan Lake. This was the one where the entire train went along since the barge was a link to an isolated section of track. The Iris G tug boat and a barge were operated under contract to CP Rail until the last train ran late in December 1988. The sternwheel steamship Moyie on Kootenay Lake was the last CPR passenger boat in BC lake service, having operated from 1898 until 1957. She became a beached historical exhibit, as are also the Sicamous and Naramata at Penticton on Lake Okanagan.
To promote tourism and passenger ridership the Canadian Pacific established a series of first class hotels. These hotels became landmarks famous in their own right. They include the Algonquin in St. Andrews, Château Frontenac in Quebec, Royal York in Toronto, Minaki Lodge in Minaki Ontario, Hotel Vancouver, Empress Hotel in Victoria and the Banff Springs Hotel and Chateau Lake Louise in the Canadian Rockies. Several signature hotels were acquired from its competitor Canadian National during the 1980s, including the Jasper Park Lodge. The hotels retain their Canadian Pacific heritage, but are no longer operated by the railway. In 1998, Canadian Pacific Hotels acquired Fairmont Hotels, an American company, becoming Fairmont Hotels and Resorts, Inc.; the combined corporation operated the historic Canadian properties as well as the Fairmont's U.S. properties until merged with Raffles Hotels and Resorts and Swissôtel in 2006.
Canadian Pacific Airlines, also called CP Air, operated from 1942 to 1987 and was the main competitor of Canadian government-owned Air Canada. Based at Vancouver International Airport, it served Canadian and international routes until it was purchased by Pacific Western Airlines which merged PWA and CP Air to create Canadian Airlines.
In the CPR's early years, it made extensive use of American-type 4-4-0 steam locomotives, and such examples of this are the Countess of Dufferin or No. 29. Later, considerable use was also made of the 4-6-0 type for passenger and 2-8-0 type for freight. Starting in the 20th century, the CPR bought and built hundreds of Ten-Wheeler-type 4-6-0s for passenger and freight service and similar quantities of 2-8-0s and 2-10-2s for freight. 2-10-2s were also used in passenger service on mountain routes. The CPR bought hundreds of 4-6-2 Pacifics between 1906 and 1948 with later versions being true dual-purpose passenger and fast-freight locomotives.
The CPR built hundreds of its own locomotives at its shops in Montreal, first at the "New Shops", as the DeLorimer shops were commonly referred to, and at the massive Angus Shops that replaced them in 1904. Some of the CPR's best-known locomotives were the 4-6-4 Hudsons. First built in 1929, they began a new era of modern locomotives with capabilities that changed how transcontinental passenger trains ran, eliminating frequent changes en route. What once took 24 changes of engines in 1886, all of them 4-4-0s except for two of 2-8-0s in the mountains, for 4,640 kilometres (2,883 mi) between Montreal and Vancouver became 8 changes. The 2800s, as the Hudson type was known, ran from Toronto to Fort William, a distance of 1,305 kilometres (811 mi), while another lengthy engine district was from Winnipeg to Calgary 1,339 kilometres (832 mi). Especially notable were the semi-streamlined H1 class Royal Hudsons, locomotives that were given their name because one of their class hauled the royal train carrying King George VI and Queen Elizabeth on the 1939 royal tour across Canada without change or failure. That locomotive, No. 2850, is preserved in the Exporail exhibit hall of the Canadian Railway Museum in Saint-Constant, Quebec. One of the class, No. 2860, was restored by the British Columbia government and used in excursion service on the British Columbia Railway between 1974 and 1999.
The CPR also made many of their older 2-8-0s, built in the turn of the century, into 2-8-2s.
In 1929, the CPR received its first 2-10-4 Selkirk locomotives, the largest steam locomotives to run in Canada and the British Empire. Named after the Selkirk Mountains where they served, these locomotives were well suited for steep grades. They were regularly used in passenger and freight service. The CPR would own 37 of these locomotives, including number 8000, an experimental high pressure engine. The last steam locomotives that the CPR received, in 1949, were Selkirks, numbered 5930–5935.
In 1937, the CPR acquired its first diesel-electric locomotive, a custom-built one-of-a-kind switcher numbered 7000. This locomotive was not successful and was not repeated. Production-model diesels were imported from American Locomotive Company (Alco) starting with five model S-2 yard switchers in 1943 and followed by further orders. In 1949, operations on lines in Vermont were dieselized with Alco FA1 road locomotives (eight A and four B units), five ALCO RS-2 road switchers, three Alco S-2 switchers and three EMD E8 passenger locomotives. In 1948 Montreal Locomotive Works began production of ALCO designs.
In 1949, the CPR acquired 13 Baldwin-designed locomotives from the Canadian Locomotive Company for its isolated Esquimalt and Nanaimo Railway and Vancouver Island was quickly dieselized. Following that successful experiment, the CPR started to dieselize its main network. Dieselization was completed 11 years later, with its last steam locomotive running on 6 November 1960. The CPR's first-generation locomotives were mostly made by General Motors Diesel and Montreal Locomotive Works (American Locomotive Company designs), with some made by the Canadian Locomotive Company to Baldwin and Fairbanks Morse designs.
CP was the first railway in North America to pioneer alternating current (AC) traction diesel-electric locomotives in 1984. In 1995, CP turned to GE Transportation for the first production AC traction locomotives in Canada, and now has the highest percentage of AC locomotives in service of all North American Class I railways.
On 16 September 2019, Progress Rail rolled out two SD70ACU rebuilds in Canadian Pacific heritage paint schemes; 7010 wears a Tuscan red and grey paint scheme with script writing, and the 7015 wears a similar paint scheme with block lettering.
On 11 November 2019, five SD70ACU units with commemorative military themes were unveiled during CPR's Remembrance Day ceremony. These units are numbered 7020–7023, with 7024 being renumbered to 6644 to commemorate the date of D-Day: 6 June 1944.
In 2021 Canadian Pacific repainted two locomotives orange: ES44AC 8757 which was unveiled for National Day for Truth and Reconciliation in September 2021, and ES44AC 8781 to commemorate shipper Hapag-Lloyd.

Canadian Pacific Railway Limited (TSX: CP NYSE: CP) is a Canadian railway transportation company that operates the Canadian Pacific Railway. It was created in 2001 when the CPR's former parent company, Canadian Pacific Limited, spun off its railway operations. On 3 October 2001, the company's shares began to trade on the New York Stock Exchange and the Toronto Stock Exchange under the "CP" symbol. During 2003, the company earned CA$3.5 billion in freight revenue. In October 2008, Canadian Pacific Railway Ltd was named one of "Canada's Top 100 Employers" by Mediacorp Canada Inc., and was featured in Maclean's. Later that month, CPR was named one of Alberta's Top Employers, which was reported in both the Calgary Herald and the Edmonton Journal.
CP owned a large number of large yards and repair shops across their system, which were used for many operations ranging from intermodal terminals to classification yards. Below are some examples of these.
Hump yards work by using a small hill over which cars are pushed, before being released down a slope and switched automatically into cuts of cars, ready to be made into outbound trains. Many of these yards were closed in 2012 and 2013 under Hunter Harrison's company-wide restructuring; only the St. Paul Yard hump remains open.

In 1873, Macdonald, among other high-ranking politicians, bribed in the Pacific Scandal, granted contracts to the Canada Pacific Railway Company, which was unrelated to the current company, as opposed to the Inter-Ocean Railway Company, which was thought to have connections to the Northern Pacific Railway Company in the United States. After this scandal, the Conservatives were removed from power, and Alexander Mackenzie, the new Liberal prime minister, ordered construction of the railway under the supervision of the Department of Public Works. Macdonald would later return as prime minister and adopt a more aggressive construction policy; bonds were floated in London and caleld for tenders to complete sections of the railway in British Columbia. American contractor Andrew Onderdonk was selected, and his men began construction on 15 May 1880.",

Fifty-two CPR ships were pressed into service during World War I, carrying more than a million troops and passengers and four million tons of cargo. Twenty seven survived and returned to CPR. CPR also helped the war effort with money and jobs. CPR made loans and guarantees to the Allies of some $100 million.

Grain has always been a significant commodity hauled by the CPR; between 1905 and 1909, the CPR double-tracked its section of track between Fort William, Ontario (part of present-day Thunder Bay) and Winnipeg to facilitate grain shipments. For several decades this was the only long stretch of double-track mainline outside of urban areas on the CPR.

Greatly reduced travel times and reduced costs resulted, which saved service on many lines for a number of years. The CPR went on to acquire the second largest fleet of RDCs totalling 52 cars. Only the Boston and Maine Railroad had more. This CPR fleet also included the rare model RDC-4 (which consisted of a mail section at one end and a baggage section at the other end with no formal passenger section). On 24 April 1955, the CPR introduced a new luxury transcontinental passenger train, The Canadian. The train provided service between Vancouver and Toronto or Montreal (east of Sudbury; the train was in two sections). The train, which operated on an expedited schedule, was pulled by diesel locomotives, and used new, streamlined, stainless steel rolling stock. This service was initially heavily promoted by the company and many images of the train, especially as it traversed the Canadian Rockies, were captured by CPR's official photographer Nicholas Morant.

For example, passenger service ended on its line through southern British Columbia and Crowsnest Pass in January 1964, and on its Quebec Central in April 1967, and the transcontinental train The Dominion was dropped in January 1966. On 29 October 1978, CP Rail transferred its passenger services to Via Rail, a new federal Crown corporation that was now responsible for intercity passenger services in Canada. Canadian Prime Minister Brian Mulroney presided over major cuts in Via Rail service on 15 January 1990. This ended service by The Canadian over CPR rails, and the train was rerouted on the former Super Continental route via Canadian National without a change of name. Where both trains had been daily prior to the 15 January 1990 cuts, the surviving Canadian was only a three-times-weekly operation. In October 2012, The Canadian was reduced to twice-weekly for the six-month off-season period, and currently operates three-times-weekly for only six months a year. In addition to inter-city passenger services, the CPR also provided commuter rail services in Montreal. CP Rail introduced Canada's first bi-level passenger cars here in 1970.

Pullman was long a famous name in this regard; its Pullman porters were legendary. Other early companies included the Wagner Palace Car Company. Bigger-sized berths and more comfortable surroundings were built by order of the CPR's General Manager, William Van Horne, who was a large man himself. Providing and operating their own cars allowed better control of the service provided as well as keeping all of the revenue received, although dining-car services were never profitable.

The CPR's most notable royal train was in 1939, when the CPR and the CNR had the honour of carrying King George VI and Queen Elizabeth during their coast-to-coast-and-back tour of Canada; one company took the royal couple from Quebec City to Vancouver and the other company took them on the return journey to Halifax.

These two segments became Canadian Pacific Ocean Services (later, Canadian Pacific Steamships) and operated separately from the various lake services operated in Canada, which were considered to be a direct part of the railway's operations. These trans-ocean routes made it possible to travel from Britain to Hong Kong using only the CPR's ships, trains and hotels. CP's 'Empress' ships became world-famous for their luxury and speed. They had a practical role, too, in transporting immigrants from much of Europe to Canada, especially to populate the vast prairies. They also played an important role in both world wars with many of them being lost to enemy action, including Empress of Britain.",

This service ended in 1915 when the CPR made an agreement with the Michigan Central to use their Detroit River tunnel opened in 1910. Pennsylvania-Ontario Transportation Company was formed jointly with the PRR in 1906 to operate a ferry across Lake Erie between Ashtabula, Ohio, and Port Burwell, Ontario, to carry freight cars, mostly of coal, much of it to be burned in CPR steam locomotives. Only one ferry boat was ever operated, Ashtabula, a large vessel which eventually sank in a harbour collision in Ashtabula on 18 September 1958, thus ending the service.",

A bridge built in 1958 ended passenger service however, freight continued until Ogdensburg's dock was destroyed by fire 25 September 1970, thus ending all service. CPC&PTC was never owned by the CPR. Bay of Fundy ferry service was operated for passengers and freight for many years linking Digby, Nova Scotia, and Saint John, New Brunswick. Eventually, after 78 years, with the changing times the scheduled passenger services would all be ended as well as ocean cruises. Cargo would continue on both oceans with a change over to containers. CP was an intermodal pioneer especially on land with road and railway mixing to provide the best service. CP Ships was the final operation, and in the end it too left CP ownership when it was spun off in 2001. CP Ships was merged with Hapag-Lloyd in 2005.",

Service included the Vancouver-Victoria-Seattle Triangle Route, Gulf Islands, Powell River, as well as Vancouver-Alaska service. BCCS operated a fleet of 14 passenger ships made up of a number of Princess ships, pocket versions of the famous oceangoing Empress ships along with a freighter, three tugs and five railway car barges. Popular with tourists, the Princess ships were famous in their own right especially Princess Marguerite (II) which operated from 1949 until 1985 and was the last coastal liner in operation. The best known of the princess ships, however, is Princess Sophia, which sank with no survivors in October 1918 after striking the Vanderbilt Reef in Alaska's Lynn Canal, constituting the largest maritime disaster in the history of the Pacific Northwest. These services continued for many years until changing conditions in the late 1950s brought about their decline and eventual demise at the end of season in 1974. Princess Marguerite was acquired by the province's British Columbia Steamship (1975) Ltd. and continued to operate for a number of years. In 1977 although BCCSS was the legal name, it was rebranded as Coastal Marine Operations (CMO). By 1998 the company was bought by the Washington Marine Group which after purchase was renamed Seaspan Coastal Intermodal Company and then subsequently rebranded in 2011 as Seaspan Ferries Corporation.

] | The Canadian Pacific Railway, also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996), was a Canadian Class I railway incorporated in 1881. The railway was owned by Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001. Headquartered in Calgary, Alberta, the railway owned approximately 20,100 kilometres (12,500 mi) of track in seven provinces of Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also served Minneapolis–St. Paul, Milwaukee, Detroit, Chicago, and Albany, New York, in the United States. The railway was first built between eastern Canada and British Columbia between 1881 and 1885, fulfilling a commitment extended to British Columbia when it entered Confederation in 1871; the CPR was Canada's first transcontinental railway. Primarily a freight railway, the CPR was for decades the only practical means of long-distance passenger transport in most regions of Canada and was instrumental in the settlement and development of Western Canada. The CPR became one of the largest and most powerful companies in Canada, a position it held as late as 1975. The company acquired two American lines in 2009: the Dakota, Minnesota and Eastern Railroad (DM&E) and the Iowa, Chicago and Eastern Railroad (IC&E). The trackage of the IC&E was at one time part of CP subsidiary Soo Line and predecessor line The Milwaukee Road. The combined DM&E/IC&E system spanned North Dakota, South Dakota, Minnesota, Wisconsin, Nebraska and Iowa, with two lines stretching into Kansas City, Missouri, and Chicago, Illinois. Also, the company owns the Indiana Harbor Belt Railroad, a Hammond, Indiana-based terminal railroad along with Conrail Shared Assets Operations. CP's ownership of that railroad traces back to the Soo Line's ownership, inherited from the Milwaukee Road. The CPR is publicly traded on both the Toronto Stock Exchange and the New York Stock Exchange under the ticker CP. Its U.S. headquarters are in Minneapolis. As of March 30, 2023, the largest shareholder of Canadian Pacific stock exchange is TCI Fund Management Limited, a London-based hedge fund that owns 6% of the company. CP purchased the Kansas City Southern Railway in December 2021 for US$31 billion. On April 14, 2023, the railroads merged to form CPKC, the first and only railroad to directly serve Canada, Mexico and the United States. | 2001-07-28T22:44:19Z | 2023-12-31T11:04:41Z | [

5,961 | Cognitive psychology | Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning.
Cognitive psychology originated in the 1960s in a break from behaviourism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. The domain of cognitive psychology overlaps with that of cognitive science, which takes a more interdisciplinary approach and includes studies of non-human subjects and artificial intelligence.
Philosophically, ruminations on the human mind and its processes have been around since the times of the ancient Greeks. In 387 BCE, Plato had suggested that the brain was the seat of the mental processes. In 1637, René Descartes posited that humans are born with innate ideas and forwarded the idea of mind-body dualism, which would come to be known as substance dualism (essentially the idea that the mind and the body are two separate substances). From that time, major debates ensued through the 19th century regarding whether human thought was solely experiential (empiricism), or included innate knowledge (nativism). Some of those involved in this debate included George Berkeley and John Locke on the side of empiricism, and Immanuel Kant on the side of nativism.
With the philosophical debate continuing, the mid to late 19th century was a critical time in the development of psychology as a scientific discipline. Two discoveries that would later play substantial roles in cognitive psychology were Paul Broca's discovery of the area of the brain largely responsible for language production, and Carl Wernicke's discovery of an area thought to be mostly responsible for comprehension of language. Both areas were subsequently formally named for their founders, and disruptions of an individual's language production or comprehension due to trauma or malformation in these areas have come to commonly be known as Broca's aphasia and Wernicke's aphasia.
From the 1920s to the 1950s, the main approach to psychology was behaviorism. Initially, its adherents viewed mental events such as thoughts, ideas, attention, and consciousness as unobservables, hence outside the realm of a science of psychology. One pioneer of cognitive psychology, who worked outside the boundaries (both intellectual and geographical) of behaviorism was Jean Piaget. From 1926 to the 1950s and into the 1980s, he studied the thoughts, language, and intelligence of children and adults.
In the mid-20th century, three main influences arose that would inspire and shape cognitive psychology as a formal school of thought:
Ulric Neisser put the term "cognitive psychology" into common use through his book Cognitive Psychology, published in 1967. Neisser's definition of "cognition" illustrates the then-progressive concept of cognitive processes:
The term "cognition" refers to all processes by which the sensory input is transformed, reduced, elaborated, stored, recovered, and used. It is concerned with these processes even when they operate in the absence of relevant stimulation, as in images and hallucinations. ... Given such a sweeping definition, it is apparent that cognition is involved in everything a human being might possibly do; that every psychological phenomenon is a cognitive phenomenon. But although cognitive psychology is concerned with all human activity rather than some fraction of it, the concern is from a particular point of view. Other viewpoints are equally legitimate and necessary. Dynamic psychology, which begins with motives rather than with sensory input, is a case in point. Instead of asking how a man's actions and experiences result from what he saw, remembered, or believed, the dynamic psychologist asks how they follow from the subject's goals, needs, or instincts.
The main focus of cognitive psychologists is on the mental processes that affect behavior. Those processes include, but are not limited to, the following three stages of memory:
The psychological definition of attention is "a state of focused awareness on a subset of the available sensation perception information". A key function of attention is to identify irrelevant data and filter it out, enabling significant data to be distributed to the other mental processes. For example, the human brain may simultaneously receive auditory, visual, olfactory, taste, and tactile information. The brain is able to consciously handle only a small subset of this information, and this is accomplished through the attentional processes.
Attention can be divided into two major attentional systems: exogenous control and endogenous control. Exogenous control works in a bottom-up manner and is responsible for orienting reflex, and pop-out effects. Endogenous control works top-down and is the more deliberate attentional system, responsible for divided attention and conscious processing.
One major focal point relating to attention within the field of cognitive psychology is the concept of divided attention. A number of early studies dealt with the ability of a person wearing headphones to discern meaningful conversation when presented with different messages into each ear; this is known as the dichotic listening task. Key findings involved an increased understanding of the mind's ability to both focus on one message, while still being somewhat aware of information being taken in from the ear not being consciously attended to. For example, participants (wearing earphones) may be told that they will be hearing separate messages in each ear and that they are expected to attend only to information related to basketball. When the experiment starts, the message about basketball will be presented to the left ear and non-relevant information will be presented to the right ear. At some point the message related to basketball will switch to the right ear and the non-relevant information to the left ear. When this happens, the listener is usually able to repeat the entire message at the end, having attended to the left or right ear only when it was appropriate. The ability to attend to one conversation in the face of many is known as the cocktail party effect.
Other major findings include that participants cannot comprehend both passages when shadowing one passage, they cannot report the content of the unattended message, while they can shadow a message better if the pitches in each ear are different. However, while deep processing does not occur, early sensory processing does. Subjects did notice if the pitch of the unattended message changed or if it ceased altogether, and some even oriented to the unattended message if their name was mentioned.
The two main types of memory are short-term memory and long-term memory; however, short-term memory has become better understood to be working memory. Cognitive psychologists often study memory in terms of working memory.
Though working memory is often thought of as just short-term memory, it is more clearly defined as the ability to process and maintain temporary information in a wide range of everyday activities in the face of distraction. The famously known capacity of memory of 7 plus or minus 2 is a combination of both memories in working memory and long-term memory.
One of the classic experiments is by Ebbinghaus, who found the serial position effect where information from the beginning and end of the list of random words were better recalled than those in the center. This primacy and recency effect varies in intensity based on list length. Its typical U-shaped curve can be disrupted by an attention-grabbing word; this is known as the Von Restorff effect.
Many models of working memory have been made. One of the most regarded is the Baddeley and Hitch model of working memory. It takes into account both visual and auditory stimuli, long-term memory to use as a reference, and a central processor to combine and understand it all.
A large part of memory is forgetting, and there is a large debate among psychologists of decay theory versus interference theory.
Modern conceptions of memory are usually about long-term memory and break it down into three main sub-classes. These three classes are somewhat hierarchical in nature, in terms of the level of conscious thought related to their use.
Perception involves both the physical senses (sight, smell, hearing, taste, touch, and proprioception) as well as the cognitive processes involved in interpreting those senses. Essentially, it is how people come to understand the world around them through the interpretation of stimuli. Early psychologists like Edward B. Titchener began to work with perception in their structuralist approach to psychology. Structuralism dealt heavily with trying to reduce human thought (or "consciousness", as Titchener would have called it) into its most basic elements by gaining an understanding of how an individual perceives particular stimuli.
Current perspectives on perception within cognitive psychology tend to focus on particular ways in which the human mind interprets stimuli from the senses and how these interpretations affect behavior. An example of the way in which modern psychologists approach the study of perception is the research being done at the Center for Ecological Study of Perception and Action at the University of Connecticut (CESPA). One study at CESPA concerns ways in which individuals perceive their physical environment and how that influences their navigation through that environment.
Psychologists have had an interest in the cognitive processes involved with language that dates back to the 1870s, when Carl Wernicke proposed a model for the mental processing of language. Current work on language within the field of cognitive psychology varies widely. Cognitive psychologists may study language acquisition, individual components of language formation (like phonemes), how language use is involved in mood, or numerous other related areas.
Significant work has focused on understanding the timing of language acquisition and how it can be used to determine if a child has, or is at risk of, developing a learning disability. A study from 2012 showed that, while this can be an effective strategy, it is important that those making evaluations include all relevant information when making their assessments. Factors such as individual variability, socioeconomic status, short-term and long-term memory capacity, and others must be included in order to make valid assessments.
Metacognition, in a broad sense, is the thoughts that a person has about their own thoughts. More specifically, metacognition includes things like:
Much of the current study regarding metacognition within the field of cognitive psychology deals with its application within the area of education. Being able to increase a student's metacognitive abilities has been shown to have a significant impact on their learning and study habits. One key aspect of this concept is the improvement of students' ability to set goals and self-regulate effectively to meet those goals. As a part of this process, it is also important to ensure that students are realistically evaluating their personal degree of knowledge and setting realistic goals (another metacognitive task).
Common phenomena related to metacognition include:
Modern perspectives on cognitive psychology generally address cognition as a dual process theory, expounded upon by Daniel Kahneman in 2011. Kahneman differentiated the two styles of processing more, calling them intuition and reasoning. Intuition (or system 1), similar to associative reasoning, was determined to be fast and automatic, usually with strong emotional bonds included in the reasoning process. Kahneman said that this kind of reasoning was based on formed habits and very difficult to change or manipulate. Reasoning (or system 2) was slower and much more volatile, being subject to conscious judgments and attitudes.
Following the cognitive revolution, and as a result of many of the principal discoveries to come out of the field of cognitive psychology, the discipline of cognitive behavior therapy (CBT) evolved. Aaron T. Beck is generally regarded as the father of cognitive therapy, a particular type of CBT treatment. His work in the areas of recognition and treatment of depression has gained worldwide recognition. In his 1987 book titled Cognitive Therapy of Depression, Beck puts forth three salient points with regard to his reasoning for the treatment of depression by means of therapy or therapy and antidepressants versus using a pharmacological-only approach:
1. Despite the prevalent use of antidepressants, the fact remains that not all patients respond to them. Beck cites (in 1987) that only 60 to 65% of patients respond to antidepressants, and recent meta-analyses (a statistical breakdown of multiple studies) show very similar numbers.2. Many of those who do respond to antidepressants end up not taking their medications, for various reasons. They may develop side-effects or have some form of personal objection to taking the drugs.3. Beck posits that the use of psychotropic drugs may lead to an eventual breakdown in the individual's coping mechanisms. His theory is that the person essentially becomes reliant on the medication as a means of improving mood and fails to practice those coping techniques typically practiced by healthy individuals to alleviate the effects of depressive symptoms. By failing to do so, once the patient is weaned off of the antidepressants, they often are unable to cope with normal levels of depressed mood and feel driven to reinstate use of the antidepressants.
Many facets of modern social psychology have roots in research done within the field of cognitive psychology. Social cognition is a specific sub-set of social psychology that concentrates on processes that have been of particular focus within cognitive psychology, specifically applied to human interactions. Gordon B. Moskowitz defines social cognition as "... the study of the mental processes involved in perceiving, attending to, remembering, thinking about, and making sense of the people in our social world".
The development of multiple social information processing (SIP) models has been influential in studies involving aggressive and anti-social behavior. Kenneth Dodge's SIP model is one of, if not the most, empirically supported models relating to aggression. Among his research, Dodge posits that children who possess a greater ability to process social information more often display higher levels of socially acceptable behavior; that the type of social interaction that children have affects their relationships. His model asserts that there are five steps that an individual proceeds through when evaluating interactions with other individuals and that how the person interprets cues is key to their reactionary process.
Many of the prominent names in the field of developmental psychology base their understanding of development on cognitive models. One of the major paradigms of developmental psychology, the Theory of Mind (ToM), deals specifically with the ability of an individual to effectively understand and attribute cognition to those around them. This concept typically becomes fully apparent in children between the ages of 4 and 6. Essentially, before the child develops ToM, they are unable to understand that those around them can have different thoughts, ideas, or feelings than themselves. The development of ToM is a matter of metacognition, or thinking about one's thoughts. The child must be able to recognize that they have their own thoughts and in turn, that others possess thoughts of their own.
One of the foremost minds with regard to developmental psychology, Jean Piaget, focused much of his attention on cognitive development from birth through adulthood. Though there have been considerable challenges to parts of his stages of cognitive development, they remain a staple in the realm of education. Piaget's concepts and ideas predated the cognitive revolution but inspired a wealth of research in the field of cognitive psychology and many of his principles have been blended with modern theory to synthesize the predominant views of today.
Modern theories of education have applied many concepts that are focal points of cognitive psychology. Some of the most prominent concepts include:
Cognitive therapeutic approaches have received considerable attention in the treatment of personality disorders in recent years. The approach focuses on the formation of what it believes to be faulty schemata, centralized on judgmental biases and general cognitive errors.
The line between cognitive psychology and cognitive science can be blurry. Cognitive psychology is better understood as predominantly concerned with applied psychology and the understanding of psychological phenomena. Cognitive psychologists are often heavily involved in running psychological experiments involving human participants, with the goal of gathering information related to how the human mind takes in, processes, and acts upon inputs received from the outside world. The information gained in this area is then often used in the applied field of clinical psychology.
Cognitive science is better understood as predominantly concerned with a much broader scope, with links to philosophy, linguistics, anthropology, neuroscience, and particularly with artificial intelligence. It could be said that cognitive science provides the corpus of information feeding the theories used by cognitive psychologists. Cognitive scientists' research sometimes involves non-human subjects, allowing them to delve into areas which would come under ethical scrutiny if performed on human participants. For instance, they may do research implanting devices in the brains of rats to track the firing of neurons while the rat performs a particular task. Cognitive science is highly involved in the area of artificial intelligence and its application to the understanding of mental processes.
Some observers have suggested that as cognitive psychology became a movement during the 1970s, the intricacies of the phenomena and processes it examined meant it also began to lose cohesion as a field of study. In Psychology: Pythagoras to Present, for example, John Malone writes: "Examinations of late twentieth-century textbooks dealing with "cognitive psychology", "human cognition", "cognitive science" and the like quickly reveal that there are many, many varieties of cognitive psychology and very little agreement about exactly what may be its domain." This misfortune produced competing models that questioned information-processing approaches to cognitive functioning such as Decision Making and Behavioral Sciences.
In the early years of cognitive psychology, behaviorist critics held that the empiricism it pursued was incompatible with the concept of internal mental states. However, cognitive neuroscience continues to gather evidence of direct correlations between physiological brain activity and mental states, endorsing the basis for cognitive psychology.
There is however disagreement between neuropsychologists and cognitive psychologists. Cognitive psychology has produced models of cognition which are not supported by modern brain science. It is often the case that the advocates of different cognitive models form a dialectic relationship with one another thus affecting empirical research, with researchers siding with their favorite theory. For example, advocates of mental model theory have attempted to find evidence that deductive reasoning is based on image thinking, while the advocates of mental logic theory have tried to prove that it is based on verbal thinking, leading to a disorderly picture of the findings from brain imaging and brain lesion studies. When theoretical claims are put aside, the evidence shows that interaction depends on the type of task tested, whether of visuospatial or linguistical orientation; but that there is also an aspect of reasoning which is not covered by either theory.
Similarly, neurolinguistics has found that it is easier to make sense of brain imaging studies when the theories are left aside. In the field of language cognition research, generative grammar has taken the position that language resides within its private cognitive module, while 'Cognitive Linguistics' goes to the opposite extreme by claiming that language is not an independent function, but operates on general cognitive capacities such as visual processing and motor skills. Consensus in neuropsychology however takes the middle position that, while language is a specialized function, it overlaps or interacts with visual processing. Nonetheless, much of the research in language cognition continues to be divided along the lines of generative grammar and Cognitive Linguistics; and this, again, affects adjacent research fields including language development and language acquisition.

In 387 BCE, Plato had suggested that the brain was the seat of the mental processes. In 1637, René Descartes posited that humans are born with innate ideas and forwarded the idea of mind-body dualism, which would come to be known as substance dualism (essentially the idea that the mind and the body are two separate substances). From that time, major debates ensued through the 19th century regarding whether human thought was solely experiential (empiricism), or included innate knowledge (nativism). Some of those involved in this debate included George Berkeley and John Locke on the side of empiricism, and Immanuel Kant on the side of nativism.",

Given such a sweeping definition, it is apparent that cognition is involved in everything a human being might possibly do; that every psychological phenomenon is a cognitive phenomenon. But although cognitive psychology is concerned with all human activity rather than some fraction of it, the concern is from a particular point of view. Other viewpoints are equally legitimate and necessary. Dynamic psychology, which begins with motives rather than with sensory input, is a case in point. Instead of asking how a man's actions and experiences result from what he saw, remembered, or believed, the dynamic psychologist asks how they follow from the subject's goals, needs, or instincts.",

Key findings involved an increased understanding of the mind's ability to both focus on one message, while still being somewhat aware of information being taken in from the ear not being consciously attended to. For example, participants (wearing earphones) may be told that they will be hearing separate messages in each ear and that they are expected to attend only to information related to basketball. When the experiment starts, the message about basketball will be presented to the left ear and non-relevant information will be presented to the right ear. At some point the message related to basketball will switch to the right ear and the non-relevant information to the left ear. When this happens, the listener is usually able to repeat the entire message at the end, having attended to the left or right ear only when it was appropriate. The ability to attend to one conversation in the face of many is known as the cocktail party effect.",

Beck posits that the use of psychotropic drugs may lead to an eventual breakdown in the individual's coping mechanisms. His theory is that the person essentially becomes reliant on the medication as a means of improving mood and fails to practice those coping techniques typically practiced by healthy individuals to alleviate the effects of depressive symptoms.

5,962 | Comet | A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions.
Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the nearest star. Long-period comets are set in motion towards the Sun by gravitational perturbations from passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. The appearance of a comet is called an apparition.
Extinct comets that have passed close to the Sun many times have lost nearly all of their volatile ices and dust and may come to resemble small asteroids. Asteroids are thought to have a different origin from comets, having formed inside the orbit of Jupiter rather than in the outer Solar System. However, the discovery of main-belt comets and active centaur minor planets has blurred the distinction between asteroids and comets. In the early 21st century, the discovery of some minor bodies with long-period comet orbits, but characteristics of inner solar system asteroids, were called Manx comets. They are still classified as comets, such as C/2014 S3 (PANSTARRS). Twenty-seven Manx comets were found from 2013 to 2017.
As of November 2021, there are 4,584 known comets. However, this represents a very small fraction of the total potential comet population, as the reservoir of comet-like bodies in the outer Solar System (in the Oort cloud) is about one trillion. Roughly one comet per year is visible to the naked eye, though many of those are faint and unspectacular. Particularly bright examples are called "great comets". Comets have been visited by uncrewed probes such as NASA's Deep Impact, which blasted a crater on Comet Tempel 1 to study its interior, and the European Space Agency's Rosetta, which became the first to land a robotic spacecraft on a comet.
The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek. Κομήτης was derived from κομᾶν (koman) 'to wear the hair long', which was itself derived from κόμη (komē) 'the hair of the head' and was used to mean 'the tail of a comet'.
The astronomical symbol for comets (represented in Unicode) is U+2604 ☄ COMET, consisting of a small disc with three hairlike extensions.
The solid, core structure of a comet is known as the nucleus. Cometary nuclei are composed of an amalgamation of rock, dust, water ice, and frozen carbon dioxide, carbon monoxide, methane, and ammonia. As such, they are popularly described as "dirty snowballs" after Fred Whipple's model. Comets with a higher dust content have been called "icy dirtballs". The term "icy dirtballs" arose after observation of Comet 9P/Tempel 1 collision with an "impactor" probe sent by NASA Deep Impact mission in July 2005. Research conducted in 2014 suggests that comets are like "deep fried ice cream", in that their surfaces are formed of dense crystalline ice mixed with organic compounds, while the interior ice is colder and less dense.
The surface of the nucleus is generally dry, dusty or rocky, suggesting that the ices are hidden beneath a surface crust several metres thick. The nuclei contains a variety of organic compounds, which may include methanol, hydrogen cyanide, formaldehyde, ethanol, ethane, and perhaps more complex molecules such as long-chain hydrocarbons and amino acids. In 2009, it was confirmed that the amino acid glycine had been found in the comet dust recovered by NASA's Stardust mission. In August 2011, a report, based on NASA studies of meteorites found on Earth, was published suggesting DNA and RNA components (adenine, guanine, and related organic molecules) may have been formed on asteroids and comets.
The outer surfaces of cometary nuclei have a very low albedo, making them among the least reflective objects found in the Solar System. The Giotto space probe found that the nucleus of Halley's Comet (1P/Halley) reflects about four percent of the light that falls on it, and Deep Space 1 discovered that Comet Borrelly's surface reflects less than 3.0%; by comparison, asphalt reflects seven percent. The dark surface material of the nucleus may consist of complex organic compounds. Solar heating drives off lighter volatile compounds, leaving behind larger organic compounds that tend to be very dark, like tar or crude oil. The low reflectivity of cometary surfaces causes them to absorb the heat that drives their outgassing processes.
Comet nuclei with radii of up to 30 kilometers (19 mi) have been observed, but ascertaining their exact size is difficult. The nucleus of 322P/SOHO is probably only 100–200 meters (330–660 ft) in diameter. A lack of smaller comets being detected despite the increased sensitivity of instruments has led some to suggest that there is a real lack of comets smaller than 100 meters (330 ft) across. Known comets have been estimated to have an average density of 0.6 g/cm (0.35 oz/cu in). Because of their low mass, comet nuclei do not become spherical under their own gravity and therefore have irregular shapes.
Roughly six percent of the near-Earth asteroids are thought to be the extinct nuclei of comets that no longer experience outgassing, including 14827 Hypnos and 3552 Don Quixote.
Results from the Rosetta and Philae spacecraft show that the nucleus of 67P/Churyumov–Gerasimenko has no magnetic field, which suggests that magnetism may not have played a role in the early formation of planetesimals. Further, the ALICE spectrograph on Rosetta determined that electrons (within 1 km (0.62 mi) above the comet nucleus) produced from photoionization of water molecules by solar radiation, and not photons from the Sun as thought earlier, are responsible for the degradation of water and carbon dioxide molecules released from the comet nucleus into its coma. Instruments on the Philae lander found at least sixteen organic compounds at the comet's surface, four of which (acetamide, acetone, methyl isocyanate and propionaldehyde) have been detected for the first time on a comet.
The streams of dust and gas thus released form a huge and extremely thin atmosphere around the comet called the "coma". The force exerted on the coma by the Sun's radiation pressure and solar wind cause an enormous "tail" to form pointing away from the Sun.
The coma is generally made of water and dust, with water making up to 90% of the volatiles that outflow from the nucleus when the comet is within 3 to 4 astronomical units (450,000,000 to 600,000,000 km; 280,000,000 to 370,000,000 mi) of the Sun. The H2O parent molecule is destroyed primarily through photodissociation and to a much smaller extent photoionization, with the solar wind playing a minor role in the destruction of water compared to photochemistry. Larger dust particles are left along the comet's orbital path whereas smaller particles are pushed away from the Sun into the comet's tail by light pressure.
Although the solid nucleus of comets is generally less than 60 kilometers (37 mi) across, the coma may be thousands or millions of kilometers across, sometimes becoming larger than the Sun. For example, about a month after an outburst in October 2007, comet 17P/Holmes briefly had a tenuous dust atmosphere larger than the Sun. The Great Comet of 1811 had a coma roughly the diameter of the Sun. Even though the coma can become quite large, its size can decrease about the time it crosses the orbit of Mars around 1.5 astronomical units (220,000,000 km; 140,000,000 mi) from the Sun. At this distance the solar wind becomes strong enough to blow the gas and dust away from the coma, and in doing so enlarging the tail. Ion tails have been observed to extend one astronomical unit (150 million km) or more.
Both the coma and tail are illuminated by the Sun and may become visible when a comet passes through the inner Solar System, the dust reflects sunlight directly while the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. Occasionally a comet may experience a huge and sudden outburst of gas and dust, during which the size of the coma greatly increases for a period of time. This happened in 2007 to Comet Holmes.
In 1996, comets were found to emit X-rays. This greatly surprised astronomers because X-ray emission is usually associated with very high-temperature bodies. The X-rays are generated by the interaction between comets and the solar wind: when highly charged solar wind ions fly through a cometary atmosphere, they collide with cometary atoms and molecules, "stealing" one or more electrons from the atom in a process called "charge exchange". This exchange or transfer of an electron to the solar wind ion is followed by its de-excitation into the ground state of the ion by the emission of X-rays and far ultraviolet photons.
Bow shocks form as a result of the interaction between the solar wind and the cometary ionosphere, which is created by the ionization of gases in the coma. As the comet approaches the Sun, increasing outgassing rates cause the coma to expand, and the sunlight ionizes gases in the coma. When the solar wind passes through this ion coma, the bow shock appears.
The first observations were made in the 1980s and 1990s as several spacecraft flew by comets 21P/Giacobini–Zinner, 1P/Halley, and 26P/Grigg–Skjellerup. It was then found that the bow shocks at comets are wider and more gradual than the sharp planetary bow shocks seen at, for example, Earth. These observations were all made near perihelion when the bow shocks already were fully developed.
The Rosetta spacecraft observed the bow shock at comet 67P/Churyumov–Gerasimenko at an early stage of bow shock development when the outgassing increased during the comet's journey toward the Sun. This young bow shock was called the "infant bow shock". The infant bow shock is asymmetric and, relative to the distance to the nucleus, wider than fully developed bow shocks.
In the outer Solar System, comets remain frozen and inactive and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from observations by the Hubble Space Telescope but these detections have been questioned. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them.
The streams of dust and gas each form their own distinct tail, pointing in slightly different directions. The tail of dust is left behind in the comet's orbit in such a manner that it often forms a curved tail called the type II or dust tail. At the same time, the ion or type I tail, made of gases, always points directly away from the Sun because this gas is more strongly affected by the solar wind than is dust, following magnetic field lines rather than an orbital trajectory. On occasions—such as when Earth passes through a comet's orbital plane, the antitail, pointing in the opposite direction to the ion and dust tails, may be seen.
The observation of antitails contributed significantly to the discovery of solar wind. The ion tail is formed as a result of the ionization by solar ultra-violet radiation of particles in the coma. Once the particles have been ionized, they attain a net positive electrical charge, which in turn gives rise to an "induced magnetosphere" around the comet. The comet and its induced magnetic field form an obstacle to outward flowing solar wind particles. Because the relative orbital speed of the comet and the solar wind is supersonic, a bow shock is formed upstream of the comet in the flow direction of the solar wind. In this bow shock, large concentrations of cometary ions (called "pick-up ions") congregate and act to "load" the solar magnetic field with plasma, such that the field lines "drape" around the comet forming the ion tail.
If the ion tail loading is sufficient, the magnetic field lines are squeezed together to the point where, at some distance along the ion tail, magnetic reconnection occurs. This leads to a "tail disconnection event". This has been observed on a number of occasions, one notable event being recorded on 20 April 2007, when the ion tail of Encke's Comet was completely severed while the comet passed through a coronal mass ejection. This event was observed by the STEREO space probe.
In 2013, ESA scientists reported that the ionosphere of the planet Venus streams outwards in a manner similar to the ion tail seen streaming from a comet under similar conditions."
Uneven heating can cause newly generated gases to break out of a weak spot on the surface of comet's nucleus, like a geyser. These streams of gas and dust can cause the nucleus to spin, and even split apart. In 2010 it was revealed dry ice (frozen carbon dioxide) can power jets of material flowing out of a comet nucleus. Infrared imaging of Hartley 2 shows such jets exiting and carrying with it dust grains into the coma.
Most comets are small Solar System bodies with elongated elliptical orbits that take them close to the Sun for a part of their orbit and then out into the further reaches of the Solar System for the remainder. Comets are often classified according to the length of their orbital periods: The longer the period the more elongated the ellipse.
Periodic comets or short-period comets are generally defined as those having orbital periods of less than 200 years. They usually orbit more-or-less in the ecliptic plane in the same direction as the planets. Their orbits typically take them out to the region of the outer planets (Jupiter and beyond) at aphelion; for example, the aphelion of Halley's Comet is a little beyond the orbit of Neptune. Comets whose aphelia are near a major planet's orbit are called its "family". Such families are thought to arise from the planet capturing formerly long-period comets into shorter orbits.
At the shorter orbital period extreme, Encke's Comet has an orbit that does not reach the orbit of Jupiter, and is known as an Encke-type comet. Short-period comets with orbital periods less than 20 years and low inclinations (up to 30 degrees) to the ecliptic are called traditional Jupiter-family comets (JFCs). Those like Halley, with orbital periods of between 20 and 200 years and inclinations extending from zero to more than 90 degrees, are called Halley-type comets (HTCs). As of 2023, 70 Encke-type comets, 100 HTCs, and 755 JFCs have been reported.
Recently discovered main-belt comets form a distinct class, orbiting in more circular orbits within the asteroid belt.
Because their elliptical orbits frequently take them close to the giant planets, comets are subject to further gravitational perturbations. Short-period comets have a tendency for their aphelia to coincide with a giant planet's semi-major axis, with the JFCs being the largest group. It is clear that comets coming in from the Oort cloud often have their orbits strongly influenced by the gravity of giant planets as a result of a close encounter. Jupiter is the source of the greatest perturbations, being more than twice as massive as all the other planets combined. These perturbations can deflect long-period comets into shorter orbital periods.
Based on their orbital characteristics, short-period comets are thought to originate from the centaurs and the Kuiper belt/scattered disc —a disk of objects in the trans-Neptunian region—whereas the source of long-period comets is thought to be the far more distant spherical Oort cloud (after the Dutch astronomer Jan Hendrik Oort who hypothesized its existence). Vast swarms of comet-like bodies are thought to orbit the Sun in these distant regions in roughly circular orbits. Occasionally the gravitational influence of the outer planets (in the case of Kuiper belt objects) or nearby stars (in the case of Oort cloud objects) may throw one of these bodies into an elliptical orbit that takes it inwards toward the Sun to form a visible comet. Unlike the return of periodic comets, whose orbits have been established by previous observations, the appearance of new comets by this mechanism is unpredictable. When flung into the orbit of the sun, and being continuously dragged towards it, tons of matter are stripped from the comets which greatly influence their lifetime; the more stripped, the shorter they live and vice versa.
Long-period comets have highly eccentric orbits and periods ranging from 200 years to thousands or even millions of years. An eccentricity greater than 1 when near perihelion does not necessarily mean that a comet will leave the Solar System. For example, Comet McNaught had a heliocentric osculating eccentricity of 1.000019 near its perihelion passage epoch in January 2007 but is bound to the Sun with roughly a 92,600-year orbit because the eccentricity drops below 1 as it moves farther from the Sun. The future orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch after leaving the planetary region and is calculated with respect to the center of mass of the Solar System. By definition long-period comets remain gravitationally bound to the Sun; those comets that are ejected from the Solar System due to close passes by major planets are no longer properly considered as having "periods". The orbits of long-period comets take them far beyond the outer planets at aphelia, and the plane of their orbits need not lie near the ecliptic. Long-period comets such as C/1999 F1 and C/2017 T2 (PANSTARRS) can have aphelion distances of nearly 70,000 AU (0.34 pc; 1.1 ly) with orbital periods estimated around 6 million years.
Single-apparition or non-periodic comets are similar to long-period comets because they have parabolic or slightly hyperbolic trajectories when near perihelion in the inner Solar System. However, gravitational perturbations from giant planets cause their orbits to change. Single-apparition comets have a hyperbolic or parabolic osculating orbit which allows them to permanently exit the Solar System after a single pass of the Sun. The Sun's Hill sphere has an unstable maximum boundary of 230,000 AU (1.1 pc; 3.6 ly). Only a few hundred comets have been seen to reach a hyperbolic orbit (e > 1) when near perihelion that using a heliocentric unperturbed two-body best-fit suggests they may escape the Solar System.
As of 2022, only two objects have been discovered with an eccentricity significantly greater than one: 1I/ʻOumuamua and 2I/Borisov, indicating an origin outside the Solar System. While ʻOumuamua, with an eccentricity of about 1.2, showed no optical signs of cometary activity during its passage through the inner Solar System in October 2017, changes to its trajectory—which suggests outgassing—indicate that it is probably a comet. On the other hand, 2I/Borisov, with an estimated eccentricity of about 3.36, has been observed to have the coma feature of comets, and is considered the first detected interstellar comet. Comet C/1980 E1 had an orbital period of roughly 7.1 million years before the 1982 perihelion passage, but a 1980 encounter with Jupiter accelerated the comet giving it the largest eccentricity (1.057) of any known solar comet with a reasonable observation arc. Comets not expected to return to the inner Solar System include C/1980 E1, C/2000 U5, C/2001 Q4 (NEAT), C/2009 R1, C/1956 R1, and C/2007 F1 (LONEOS).
Some authorities use the term "periodic comet" to refer to any comet with a periodic orbit (that is, all short-period comets plus all long-period comets), whereas others use it to mean exclusively short-period comets. Similarly, although the literal meaning of "non-periodic comet" is the same as "single-apparition comet", some use it to mean all comets that are not "periodic" in the second sense (that is, to include all comets with a period greater than 200 years).
Early observations have revealed a few genuinely hyperbolic (i.e. non-periodic) trajectories, but no more than could be accounted for by perturbations from Jupiter. Comets from interstellar space are moving with velocities of the same order as the relative velocities of stars near the Sun (a few tens of km per second). When such objects enter the Solar System, they have a positive specific orbital energy resulting in a positive velocity at infinity ( v ∞ {\displaystyle v_{\infty }\!} ) and have notably hyperbolic trajectories. A rough calculation shows that there might be four hyperbolic comets per century within Jupiter's orbit, give or take one and perhaps two orders of magnitude.
The Oort cloud is thought to occupy a vast space starting from between 2,000 and 5,000 AU (0.03 and 0.08 ly) to as far as 50,000 AU (0.79 ly) from the Sun. This cloud encases the celestial bodies that start at the middle of the Solar System—the Sun, all the way to outer limits of the Kuiper Belt. The Oort cloud consists of viable materials necessary for the creation of celestial bodies. The Solar System's planets exist only because of the planetesimals (chunks of leftover space that assisted in the creation of planets) that were condensed and formed by the gravity of the Sun. The eccentric made from these trapped planetesimals is why the Oort Cloud even exists. Some estimates place the outer edge at between 100,000 and 200,000 AU (1.58 and 3.16 ly). The region can be subdivided into a spherical outer Oort cloud of 20,000–50,000 AU (0.32–0.79 ly), and a doughnut-shaped inner cloud, the Hills cloud, of 2,000–20,000 AU (0.03–0.32 ly). The outer cloud is only weakly bound to the Sun and supplies the long-period (and possibly Halley-type) comets that fall to inside the orbit of Neptune. The inner Oort cloud is also known as the Hills cloud, named after J. G. Hills, who proposed its existence in 1981. Models predict that the inner cloud should have tens or hundreds of times as many cometary nuclei as the outer halo; it is seen as a possible source of new comets that resupply the relatively tenuous outer cloud as the latter's numbers are gradually depleted. The Hills cloud explains the continued existence of the Oort cloud after billions of years.
Exocomets beyond the Solar System have been detected and may be common in the Milky Way. The first exocomet system detected was around Beta Pictoris, a very young A-type main-sequence star, in 1987. A total of 11 such exocomet systems have been identified as of 2013, using the absorption spectrum caused by the large clouds of gas emitted by comets when passing close to their star. For ten years the Kepler space telescope was responsible for searching for planets and other forms outside of the solar system. The first transiting exocomets were found in February 2018 by a group consisting of professional astronomers and citizen scientists in light curves recorded by the Kepler Space Telescope. After Kepler Space Telescope retired in October 2018, a new telescope called TESS Telescope has taken over Kepler's mission. Since the launch of TESS, astronomers have discovered the transits of comets around the star Beta Pictoris using a light curve from TESS. Since TESS has taken over, astronomers have since been able to better distinguish exocomets with the spectroscopic method. New planets are detected by the white light curve method which is viewed as a symmetrical dip in the charts readings when a planet overshadows its parent star. However, after further evaluation of these light curves, it has been discovered that the asymmetrical patterns of the dips presented are caused by the tail of a comet or of hundreds of comets.
As a comet is heated during close passes to the Sun, outgassing of its icy components releases solid debris too large to be swept away by radiation pressure and the solar wind. If Earth's orbit sends it through that trail of debris, which is composed mostly of fine grains of rocky material, there is likely to be a meteor shower as Earth passes through. Denser trails of debris produce quick but intense meteor showers and less dense trails create longer but less intense showers. Typically, the density of the debris trail is related to how long ago the parent comet released the material. The Perseid meteor shower, for example, occurs every year between 9 and 13 August, when Earth passes through the orbit of Comet Swift–Tuttle. Halley's Comet is the source of the Orionid shower in October.
Many comets and asteroids collided with Earth in its early stages. Many scientists think that comets bombarding the young Earth about 4 billion years ago brought the vast quantities of water that now fill Earth's oceans, or at least a significant portion of it. Others have cast doubt on this idea. The detection of organic molecules, including polycyclic aromatic hydrocarbons, in significant quantities in comets has led to speculation that comets or meteorites may have brought the precursors of life—or even life itself—to Earth. In 2013 it was suggested that impacts between rocky and icy surfaces, such as comets, had the potential to create the amino acids that make up proteins through shock synthesis. The speed at which the comets entered the atmosphere, combined with the magnitude of energy created after initial contact, allowed smaller molecules to condense into the larger macro-molecules that served as the foundation for life. In 2015, scientists found significant amounts of molecular oxygen in the outgassings of comet 67P, suggesting that the molecule may occur more often than had been thought, and thus less an indicator of life as has been supposed.
It is suspected that comet impacts have, over long timescales, delivered significant quantities of water to Earth's Moon, some of which may have survived as lunar ice. Comet and meteoroid impacts are thought to be responsible for the existence of tektites and australites.
Fear of comets as acts of God and signs of impending doom was highest in Europe from AD 1200 to 1650. The year after the Great Comet of 1618, for example, Gotthard Arthusius published a pamphlet stating that it was a sign that the Day of Judgment was near. He listed ten pages of comet-related disasters, including "earthquakes, floods, changes in river courses, hail storms, hot and dry weather, poor harvests, epidemics, war and treason and high prices".
By 1700 most scholars concluded that such events occurred whether a comet was seen or not. Using Edmond Halley's records of comet sightings, however, William Whiston in 1711 wrote that the Great Comet of 1680 had a periodicity of 574 years and was responsible for the worldwide flood in the Book of Genesis, by pouring water on Earth. His announcement revived for another century fear of comets, now as direct threats to the world instead of signs of disasters. Spectroscopic analysis in 1910 found the toxic gas cyanogen in the tail of Halley's Comet, causing panicked buying of gas masks and quack "anti-comet pills" and "anti-comet umbrellas" by the public.
If a comet is traveling fast enough, it may leave the Solar System. Such comets follow the open path of a hyperbola, and as such, they are called hyperbolic comets. Solar comets are only known to be ejected by interacting with another object in the Solar System, such as Jupiter. An example of this is Comet C/1980 E1, which was shifted from an orbit of 7.1 million years around the Sun, to a hyperbolic trajectory, after a 1980 close pass by the planet Jupiter. Interstellar comets such as 1I/ʻOumuamua and 2I/Borisov never orbited the Sun and therefore do not require a 3rd-body interaction to be ejected from the Solar System.
Jupiter-family comets and long-period comets appear to follow very different fading laws. The JFCs are active over a lifetime of about 10,000 years or ~1,000 orbits whereas long-period comets fade much faster. Only 10% of the long-period comets survive more than 50 passages to small perihelion and only 1% of them survive more than 2,000 passages. Eventually most of the volatile material contained in a comet nucleus evaporates, and the comet becomes a small, dark, inert lump of rock or rubble that can resemble an asteroid. Some asteroids in elliptical orbits are now identified as extinct comets. Roughly six percent of the near-Earth asteroids are thought to be extinct comet nuclei.
The nucleus of some comets may be fragile, a conclusion supported by the observation of comets splitting apart. A significant cometary disruption was that of Comet Shoemaker–Levy 9, which was discovered in 1993. A close encounter in July 1992 had broken it into pieces, and over a period of six days in July 1994, these pieces fell into Jupiter's atmosphere—the first time astronomers had observed a collision between two objects in the Solar System. Other splitting comets include 3D/Biela in 1846 and 73P/Schwassmann–Wachmann from 1995 to 2006. Greek historian Ephorus reported that a comet split apart as far back as the winter of 372–373 BC. Comets are suspected of splitting due to thermal stress, internal gas pressure, or impact.
Comets 42P/Neujmin and 53P/Van Biesbroeck appear to be fragments of a parent comet. Numerical integrations have shown that both comets had a rather close approach to Jupiter in January 1850, and that, before 1850, the two orbits were nearly identical.
Some comets have been observed to break up during their perihelion passage, including great comets West and Ikeya–Seki. Biela's Comet was one significant example when it broke into two pieces during its passage through the perihelion in 1846. These two comets were seen separately in 1852, but never again afterward. Instead, spectacular meteor showers were seen in 1872 and 1885 when the comet should have been visible. A minor meteor shower, the Andromedids, occurs annually in November, and it is caused when Earth crosses the orbit of Biela's Comet.
Some comets meet a more spectacular end – either falling into the Sun or smashing into a planet or other body. Collisions between comets and planets or moons were common in the early Solar System: some of the many craters on the Moon, for example, may have been caused by comets. A recent collision of a comet with a planet occurred in July 1994 when Comet Shoemaker–Levy 9 broke up into pieces and collided with Jupiter.
The names given to comets have followed several different conventions over the past two centuries. Prior to the early 20th century, most comets were referred to by the year when they appeared, sometimes with additional adjectives for particularly bright comets; thus, the "Great Comet of 1680", the "Great Comet of 1882", and the "Great January Comet of 1910".
After Edmond Halley demonstrated that the comets of 1531, 1607, and 1682 were the same body and successfully predicted its return in 1759 by calculating its orbit, that comet became known as Halley's Comet. Similarly, the second and third known periodic comets, Encke's Comet and Biela's Comet, were named after the astronomers who calculated their orbits rather than their original discoverers. Later, periodic comets were usually named after their discoverers, but comets that had appeared only once continued to be referred to by the year of their appearance.
In the early 20th century, the convention of naming comets after their discoverers became common, and this remains so today. A comet can be named after its discoverers or an instrument or program that helped to find it. For example, in 2019, astronomer Gennadiy Borisov observed a comet that appeared to have originated outside of the solar system; the comet was named 2I/Borisov after him.
From ancient sources, such as Chinese oracle bones, it is known that comets have been noticed by humans for millennia. Until the sixteenth century, comets were usually considered bad omens of deaths of kings or noble men, or coming catastrophes, or even interpreted as attacks by heavenly beings against terrestrial inhabitants.
Aristotle (384–322 BC) was the first known scientist to use various theories and observational facts to employ a consistent, structured cosmological theory of comets. He believed that comets were atmospheric phenomena, due to the fact that they could appear outside of the zodiac and vary in brightness over the course of a few days. Aristotle's cometary theory arose from his observations and cosmological theory that everything in the cosmos is arranged in a distinct configuration. Part of this configuration was a clear separation between the celestial and terrestrial, believing comets to be strictly associated with the latter. According to Aristotle, comets must be within the sphere of the moon and clearly separated from the heavens. Also in the 4th century BC, Apollonius of Myndus supported the idea that comets moved like the planets. Aristotelian theory on comets continued to be widely accepted throughout the Middle Ages, despite several discoveries from various individuals challenging aspects of it.
In the 1st century AD, Seneca the Younger questioned Aristotle's logic concerning comets. Because of their regular movement and imperviousness to wind, they cannot be atmospheric, and are more permanent than suggested by their brief flashes across the sky. He pointed out that only the tails are transparent and thus cloudlike, and argued that there is no reason to confine their orbits to the zodiac. In criticizing Apollonius of Myndus, Seneca argues, "A comet cuts through the upper regions of the universe and then finally becomes visible when it reaches the lowest point of its orbit." While Seneca did not author a substantial theory of his own, his arguments would spark much debate among Aristotle's critics in the 16th and 17th centuries.
In the 1st century, Pliny the Elder believed that comets were connected with political unrest and death. Pliny observed comets as "human like", often describing their tails with "long hair" or "long beard". His system for classifying comets according to their color and shape was used for centuries.
In India, by the 6th century astronomers believed that comets were celestial bodies that re-appeared periodically. This was the view expressed in the 6th century by the astronomers Varāhamihira and Bhadrabahu, and the 10th-century astronomer Bhaṭṭotpala listed the names and estimated periods of certain comets, but it is not known how these figures were calculated or how accurate they were. In 1301, the Italian painter Giotto was the first person to accurately and anatomically portray a comet. In his work Adoration of the Magi, Giotto's depiction of Halley's Comet in the place of the Star of Bethlehem would go unmatched in accuracy until the 19th century and be bested only with the invention of photography.
Astrological interpretations of comets proceeded to take precedence clear into the 15th century, despite the presence of modern scientific astronomy beginning to take root. Comets continued to forewarn of disaster, as seen in the Luzerner Schilling chronicles and in the warnings of Pope Callixtus III. In 1578, German Lutheran bishop Andreas Celichius defined comets as "the thick smoke of human sins ... kindled by the hot and fiery anger of the Supreme Heavenly Judge". The next year, Andreas Dudith stated that "If comets were caused by the sins of mortals, they would never be absent from the sky."
Crude attempts at a parallax measurement of Halley's Comet were made in 1456, but were erroneous. Regiomontanus was the first to attempt to calculate diurnal parallax by observing the Great Comet of 1472. His predictions were not very accurate, but they were conducted in the hopes of estimating the distance of a comet from Earth.
In the 16th century, Tycho Brahe and Michael Maestlin demonstrated that comets must exist outside of Earth's atmosphere by measuring the parallax of the Great Comet of 1577. Within the precision of the measurements, this implied the comet must be at least four times more distant than from Earth to the Moon. Based on observations in 1664, Giovanni Borelli recorded the longitudes and latitudes of comets that he observed, and suggested that cometary orbits may be parabolic. Despite being a skilled astronomer, in his 1623 book The Assayer, Galileo Galilei rejected Brahe's theories on the parallax of comets and claimed that they may be a mere optical illusion, despite little personal observation. In 1625, Maestlin's student Johannes Kepler upheld that Brahe's view of cometary parallax was correct. Additionally, mathematician Jacob Bernoulli published a treatise on comets in 1682.
During the early modern period comets were studied for their astrological significance in medical disciplines. Many healers of this time considered medicine and astronomy to be inter-disciplinary and employed their knowledge of comets and other astrological signs for diagnosing and treating patients.
Isaac Newton, in his Principia Mathematica of 1687, proved that an object moving under the influence of gravity by an inverse square law must trace out an orbit shaped like one of the conic sections, and he demonstrated how to fit a comet's path through the sky to a parabolic orbit, using the comet of 1680 as an example. He describes comets as compact and durable solid bodies moving in oblique orbit and their tails as thin streams of vapor emitted by their nuclei, ignited or heated by the Sun. He suspected that comets were the origin of the life-supporting component of air. He pointed out that comets usually appear near the Sun, and therefore most likely orbit it. On their luminosity, he stated, "The comets shine by the Sun's light, which they reflect," with their tails illuminated by "the Sun's light reflected by a smoke arising from [the coma]".
In 1705, Edmond Halley (1656–1742) applied Newton's method to 23 cometary apparitions that had occurred between 1337 and 1698. He noted that three of these, the comets of 1531, 1607, and 1682, had very similar orbital elements, and he was further able to account for the slight differences in their orbits in terms of gravitational perturbation caused by Jupiter and Saturn. Confident that these three apparitions had been three appearances of the same comet, he predicted that it would appear again in 1758–59. Halley's predicted return date was later refined by a team of three French mathematicians: Alexis Clairaut, Joseph Lalande, and Nicole-Reine Lepaute, who predicted the date of the comet's 1759 perihelion to within one month's accuracy. When the comet returned as predicted, it became known as Halley's Comet.
From his huge vapouring train perhaps to shakeReviving moisture on the numerous orbs,Thro' which his long ellipsis winds; perhapsTo lend new fuel to declining suns,To light up worlds, and feed th' ethereal fire.
James Thomson The Seasons (1730; 1748)
As early as the 18th century, some scientists had made correct hypotheses as to comets' physical composition. In 1755, Immanuel Kant hypothesized in his Universal Natural History that comets were condensed from "primitive matter" beyond the known planets, which is "feebly moved" by gravity, then orbit at arbitrary inclinations, and are partially vaporized by the Sun's heat as they near perihelion. In 1836, the German mathematician Friedrich Wilhelm Bessel, after observing streams of vapor during the appearance of Halley's Comet in 1835, proposed that the jet forces of evaporating material could be great enough to significantly alter a comet's orbit, and he argued that the non-gravitational movements of Encke's Comet resulted from this phenomenon.
In the 19th century, the Astronomical Observatory of Padova was an epicenter in the observational study of comets. Led by Giovanni Santini (1787–1877) and followed by Giuseppe Lorenzoni (1843–1914), this observatory was devoted to classical astronomy, mainly to the new comets and planets orbit calculation, with the goal of compiling a catalog of almost ten thousand stars. Situated in the Northern portion of Italy, observations from this observatory were key in establishing important geodetic, geographic, and astronomical calculations, such as the difference of longitude between Milan and Padua as well as Padua to Fiume. Correspondence within the observatory, particularly between Santini and another astronomer Giuseppe Toaldo, mentioned the importance of comet and planetary orbital observations.
In 1950, Fred Lawrence Whipple proposed that rather than being rocky objects containing some ice, comets were icy objects containing some dust and rock. This "dirty snowball" model soon became accepted and appeared to be supported by the observations of an armada of spacecraft (including the European Space Agency's Giotto probe and the Soviet Union's Vega 1 and Vega 2) that flew through the coma of Halley's Comet in 1986, photographed the nucleus, and observed jets of evaporating material.
On 22 January 2014, ESA scientists reported the detection, for the first definitive time, of water vapor on the dwarf planet Ceres, the largest object in the asteroid belt. The detection was made by using the far-infrared abilities of the Herschel Space Observatory. The finding is unexpected because comets, not asteroids, are typically considered to "sprout jets and plumes". According to one of the scientists, "The lines are becoming more and more blurred between comets and asteroids." On 11 August 2014, astronomers released studies, using the Atacama Large Millimeter/Submillimeter Array (ALMA) for the first time, that detailed the distribution of HCN, HNC, H2CO, and dust inside the comae of comets C/2012 F6 (Lemmon) and C/2012 S1 (ISON).
Approximately once a decade, a comet becomes bright enough to be noticed by a casual observer, leading such comets to be designated as great comets. Predicting whether a comet will become a great comet is notoriously difficult, as many factors may cause a comet's brightness to depart drastically from predictions. Broadly speaking, if a comet has a large and active nucleus, will pass close to the Sun, and is not obscured by the Sun as seen from Earth when at its brightest, it has a chance of becoming a great comet. However, Comet Kohoutek in 1973 fulfilled all the criteria and was expected to become spectacular but failed to do so. Comet West, which appeared three years later, had much lower expectations but became an extremely impressive comet.
The Great Comet of 1577 is a well-known example of a great comet. It passed near Earth as a non-periodic comet and was seen by many, including well-known astronomers Tycho Brahe and Taqi ad-Din. Observations of this comet led to several significant findings regarding cometary science, especially for Brahe.
The late 20th century saw a lengthy gap without the appearance of any great comets, followed by the arrival of two in quick succession—Comet Hyakutake in 1996, followed by Hale–Bopp, which reached maximum brightness in 1997 having been discovered two years earlier. The first great comet of the 21st century was C/2006 P1 (McNaught), which became visible to naked eye observers in January 2007. It was the brightest in over 40 years.
A sungrazing comet is a comet that passes extremely close to the Sun at perihelion, generally within a few million kilometers. Although small sungrazers can be completely evaporated during such a close approach to the Sun, larger sungrazers can survive many perihelion passages. However, the strong tidal forces they experience often lead to their fragmentation.
About 90% of the sungrazers observed with SOHO are members of the Kreutz group, which all originate from one giant comet that broke up into many smaller comets during its first passage through the inner Solar System. The remainder contains some sporadic sungrazers, but four other related groups of comets have been identified among them: the Kracht, Kracht 2a, Marsden, and Meyer groups. The Marsden and Kracht groups both appear to be related to Comet 96P/Machholz, which is the parent of two meteor streams, the Quadrantids and the Arietids.
Of the thousands of known comets, some exhibit unusual properties. Comet Encke (2P/Encke) orbits from outside the asteroid belt to just inside the orbit of the planet Mercury whereas the Comet 29P/Schwassmann–Wachmann currently travels in a nearly circular orbit entirely between the orbits of Jupiter and Saturn. 2060 Chiron, whose unstable orbit is between Saturn and Uranus, was originally classified as an asteroid until a faint coma was noticed. Similarly, Comet Shoemaker–Levy 2 was originally designated asteroid 1990 UL3.
The largest known periodic comet is 95P/Chiron at 200 km in diameter that comes to perihelion every 50 years just inside of Saturn's orbit at 8 AU. The largest known Oort cloud comet is suspected of being Comet Bernardinelli-Bernstein at ≈150 km that will not come to perihelion until January 2031 just outside of Saturn's orbit at 11 AU. The Comet of 1729 is estimated to have been ≈100 km in diameter and came to perihelion inside of Jupiter's orbit at 4 AU.
Centaurs typically behave with characteristics of both asteroids and comets. Centaurs can be classified as comets such as 60558 Echeclus, and 166P/NEAT. 166P/NEAT was discovered while it exhibited a coma, and so is classified as a comet despite its orbit, and 60558 Echeclus was discovered without a coma but later became active, and was then classified as both a comet and an asteroid (174P/Echeclus). One plan for Cassini involved sending it to a centaur, but NASA decided to destroy it instead.
A comet may be discovered photographically using a wide-field telescope or visually with binoculars. However, even without access to optical equipment, it is still possible for the amateur astronomer to discover a sungrazing comet online by downloading images accumulated by some satellite observatories such as SOHO. SOHO's 2000th comet was discovered by Polish amateur astronomer Michał Kusiak on 26 December 2010 and both discoverers of Hale–Bopp used amateur equipment (although Hale was not an amateur).
A number of periodic comets discovered in earlier decades or previous centuries are now lost comets. Their orbits were never known well enough to predict future appearances or the comets have disintegrated. However, occasionally a "new" comet is discovered, and calculation of its orbit shows it to be an old "lost" comet. An example is Comet 11P/Tempel–Swift–LINEAR, discovered in 1869 but unobservable after 1908 because of perturbations by Jupiter. It was not found again until accidentally rediscovered by LINEAR in 2001. There are at least 18 comets that fit this category.
The depiction of comets in popular culture is firmly rooted in the long Western tradition of seeing comets as harbingers of doom and as omens of world-altering change. Halley's Comet alone has caused a slew of sensationalist publications of all sorts at each of its reappearances. It was especially noted that the birth and death of some notable persons coincided with separate appearances of the comet, such as with writers Mark Twain (who correctly speculated that he'd "go out with the comet" in 1910) and Eudora Welty, to whose life Mary Chapin Carpenter dedicated the song "Halley Came to Jackson".
In times past, bright comets often inspired panic and hysteria in the general population, being thought of as bad omens. More recently, during the passage of Halley's Comet in 1910, Earth passed through the comet's tail, and erroneous newspaper reports inspired a fear that cyanogen in the tail might poison millions, whereas the appearance of Comet Hale–Bopp in 1997 triggered the mass suicide of the Heaven's Gate cult.
In science fiction, the impact of comets has been depicted as a threat overcome by technology and heroism (as in the 1998 films Deep Impact and Armageddon), or as a trigger of global apocalypse (Lucifer's Hammer, 1979) or zombies (Night of the Comet, 1984). In Jules Verne's Off on a Comet a group of people are stranded on a comet orbiting the Sun, while a large crewed space expedition visits Halley's Comet in Sir Arthur C. Clarke's novel 2061: Odyssey Three.
The long-period comet first recorded by Pons in Florence on 15 July 1825 inspired Lydia Sigourney's humorous poem The Comet of 1825. in which all the celestial bodies argue over the comet's appearance and purpose. | [

"text": "A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions.",

The dark surface material of the nucleus may consist of complex organic compounds.

By definition long-period comets remain gravitationally bound to the Sun; those comets that are ejected from the Solar System due to close passes by major planets are no longer properly considered as having \"periods\".

Single-apparition comets have a hyperbolic or parabolic osculating orbit which allows them to permanently exit the Solar System after a single pass of the Sun. The Sun's Hill sphere has an unstable maximum boundary of 230,000 AU (1.1 pc; 3.6 ly). Only a few hundred comets have been seen to reach a hyperbolic orbit (e > 1) when near perihelion that using a heliocentric unperturbed two-body best-fit suggests they may escape the Solar System.",

This cloud encases the celestial bodies that start at the middle of the Solar System—the Sun, all the way to outer limits of the Kuiper Belt. The Oort cloud consists of viable materials necessary for the creation of celestial bodies. The Solar System's planets exist only because of the planetesimals (chunks of leftover space that assisted in the creation of planets) that were condensed and formed by the gravity of the Sun. The eccentric made from these trapped planetesimals is why the Oort Cloud even exists. Some estimates place the outer edge at between 100,000 and 200,000 AU (1.58 and 3.16 ly). The region can be subdivided into a spherical outer Oort cloud of 20,000–50,000 AU (0.32–0.79 ly), and a doughnut-shaped inner cloud, the Hills cloud, of 2,000–20,000 AU (0.03–0.32 ly). The outer cloud is only weakly bound to the Sun and supplies the long-period (and possibly Halley-type) comets that fall to inside the orbit of Neptune. The inner Oort cloud is also known as the Hills cloud, named after J. G. Hills, who proposed its existence in 1981. Models predict that the inner cloud should have tens or hundreds of times as many cometary nuclei as the outer halo; it is seen as a possible source of new comets that resupply the relatively tenuous outer cloud as the latter's numbers are gradually depleted. The Hills cloud explains the continued existence of the Oort cloud after billions of years.",

The first exocomet system detected was around Beta Pictoris, a very young A-type main-sequence star, in 1987. A total of 11 such exocomet systems have been identified as of 2013, using the absorption spectrum caused by the large clouds of gas emitted by comets when passing close to their star. For ten years the Kepler space telescope was responsible for searching for planets and other forms outside of the solar system. The first transiting exocomets were found in February 2018 by a group consisting of professional astronomers and citizen scientists in light curves recorded by the Kepler Space Telescope. After Kepler Space Telescope retired in October 2018, a new telescope called TESS Telescope has taken over Kepler's mission. Since the launch of TESS, astronomers have discovered the transits of comets around the star Beta Pictoris using a light curve from TESS. Since TESS has taken over, astronomers have since been able to better distinguish exocomets with the spectroscopic method. New planets are detected by the white light curve method which is viewed as a symmetrical dip in the charts readings when a planet overshadows its parent star. However, after further evaluation of these light curves, it has been discovered that the asymmetrical patterns of the dips presented are caused by the tail of a comet or of hundreds of comets.",

If Earth's orbit sends it through that trail of debris, which is composed mostly of fine grains of rocky material, there is likely to be a meteor shower as Earth passes through. Denser trails of debris produce quick but intense meteor showers and less dense trails create longer but less intense showers. Typically, the density of the debris trail is related to how long ago the parent comet released the material. The Perseid meteor shower, for example, occurs every year between 9 and 13 August, when Earth passes through the orbit of Comet Swift–Tuttle.

The detection of organic molecules, including polycyclic aromatic hydrocarbons, in significant quantities in comets has led to speculation that comets or meteorites may have brought the precursors of life—or even life itself—to Earth. In 2013 it was suggested that impacts between rocky and icy surfaces, such as comets, had the potential to create the amino acids that make up proteins through shock synthesis. The speed at which the comets entered the atmosphere, combined with the magnitude of energy created after initial contact, allowed smaller molecules to condense into the larger macro-molecules that served as the foundation for life. In 2015, scientists found significant amounts of molecular oxygen in the outgassings of comet 67P, suggesting that the molecule may occur more often than had been thought, and thus less an indicator of life as has been supposed.",

] | A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the nearest star. Long-period comets are set in motion towards the Sun by gravitational perturbations from passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. The appearance of a comet is called an apparition. Extinct comets that have passed close to the Sun many times have lost nearly all of their volatile ices and dust and may come to resemble small asteroids. Asteroids are thought to have a different origin from comets, having formed inside the orbit of Jupiter rather than in the outer Solar System. However, the discovery of main-belt comets and active centaur minor planets has blurred the distinction between asteroids and comets. In the early 21st century, the discovery of some minor bodies with long-period comet orbits, but characteristics of inner solar system asteroids, were called Manx comets. They are still classified as comets, such as C/2014 S3 (PANSTARRS). Twenty-seven Manx comets were found from 2013 to 2017. As of November 2021, there are 4,584 known comets. However, this represents a very small fraction of the total potential comet population, as the reservoir of comet-like bodies in the outer Solar System is about one trillion. Roughly one comet per year is visible to the naked eye, though many of those are faint and unspectacular. Particularly bright examples are called "great comets". Comets have been visited by uncrewed probes such as NASA's Deep Impact, which blasted a crater on Comet Tempel 1 to study its interior, and the European Space Agency's Rosetta, which became the first to land a robotic spacecraft on a comet. | 2001-11-05T01:16:23Z | 2023-12-22T21:59:39Z | [

5,966 | Compost | Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes, and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases.
At the simplest level, composting requires gathering a mix of "greens" (green waste) and "browns" (brown waste). Greens are materials rich in nitrogen, such as leaves, grass, and food scraps. Browns are woody materials rich in carbon, such as stalks, paper, and wood chips. The materials break down into humus in a process taking months. Composting can be a multistep, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. The decomposition process is aided by shredding the plant matter, adding water, and ensuring proper aeration by regularly turning the mixture in a process using open piles or "windrows". Fungi, earthworms, and other detritivores further break up the organic material. Aerobic bacteria and fungi manage the chemical process by converting the inputs into heat, carbon dioxide, and ammonium ions.
Composting is an important part of waste management, since food and other compostable materials make up about 20% of waste in landfills, and due to anaerobic conditions, these materials take longer to biodegrade in the landfill. Composting offers an environmentally superior alternative to using organic material for landfill because composting reduces methane emissions due to anaerobic conditions, and provides economic and environmental co-benefits. For example, compost can also be used for land and stream reclamation, wetland construction, and landfill cover.
Composting is an aerobic method of decomposing organic solid wastes, so can be used to recycle organic material. The process involves decomposing organic material into a humus-like material, known as compost, which is a good fertilizer for plants.
Composting organisms require four equally important ingredients to work effectively:
Certain ratios of these materials allow microorganisms to work at a rate that will heat up the compost pile. Active management of the pile (e.g., turning over the compost heap) is needed to maintain sufficient oxygen and the right moisture level. The air/water balance is critical to maintaining high temperatures 130–160 °F (54–71 °C) until the materials are broken down.
Composting is most efficient with a carbon-to-nitrogen ratio of about 25:1. Hot composting focuses on retaining heat to increase the decomposition rate, thus producing compost more quickly. Rapid composting is favored by having a carbon-to-nitrogen ratio of about 30 carbon units or less. Above 30, the substrate is nitrogen starved. Below 15, it is likely to outgas a portion of nitrogen as ammonia.
Nearly all dead plant and animal materials have both carbon and nitrogen in different amounts. Fresh grass clippings have an average ratio of about 15:1 and dry autumn leaves about 50:1 depending upon species. Composting is an ongoing and dynamic process; adding new sources of carbon and nitrogen consistently, as well as active management, is important.
Organisms can break down organic matter in compost if provided with the correct mixture of water, oxygen, carbon, and nitrogen. They fall into two broad categories: chemical decomposers, which perform chemical processes on the organic waste, and physical decomposers, which process the waste into smaller pieces through methods such as grinding, tearing, chewing, and digesting.
Under ideal conditions, composting proceeds through three major phases:
The time required to compost material relates to the volume of material, the particle size of the inputs (e.g. wood chips break down faster than branches), and the amount of mixing and aeration. Generally, larger piles reach higher temperatures and remain in a thermophilic stage for days or weeks. This is hot composting and is the usual method for large-scale municipal facilities and agricultural operations.
The Berkeley method produces finished compost in 18 days. It requires assembly of at least 1 cubic metre (35 cu ft) of material at the outset and needs turning every two days after an initial four-day phase. Such short processes involve some changes to traditional methods, including smaller, more homogenized particle sizes in the input materials, controlling carbon-to-nitrogen ratio (C:N) at 30:1 or less, and careful monitoring of the moisture level.
Cold composting is a slower process that can take up to a year to complete. It results from smaller piles, including many residential compost piles that receive small amounts of kitchen and garden waste over extended periods. Piles smaller than 1 cubic metre (35 cu ft) tend not to reach and maintain high temperatures. Turning is not necessary with cold composting, although a risk exists that parts of the pile may go anaerobic as it becomes compacted or waterlogged.
Composting can destroy some pathogens and seeds, by reaching temperatures above 50 °C (122 °F). Dealing with stabilized compost – i.e. composted material in which microorganisms have finished digesting the organic matter and the temperature has reached between 50 and 70 °C (122 and 158 °F) – poses very little risk, as these temperatures kill pathogens and even make oocysts unviable. The temperature at which a pathogen dies depends on the pathogen, how long the temperature is maintained (seconds to weeks), and pH.
Compost products such as compost tea and compost extracts have been found to have an inhibitory effect on Fusarium oxysporum, Rhizoctonia species, and Pythium debaryanum, plant pathogens that can cause crop diseases. Aerated compost teas are more effective than compost extracts. The microbiota and enzymes present in compost extracts also have a suppressive effect on fungal plant pathogens. Compost is a good source of biocontrol agents like B. subtilis, B. licheniformis, and P. chrysogenum that fight plant pathogens. Sterilizing the compost, compost tea, or compost extracts reduces the effect of pathogen suppression.
When turning compost that has not gone through phases where temperatures above 50 °C (122 °F) are reached, a mouth mask and gloves must be worn to protect from diseases that can be contracted from handling compost, including:
Oocytes are rendered unviable by temperatures over 50 °C (122 °F).
Composting at home reduces the amount of green waste being hauled to dumps or composting facilities. The reduced volume of materials being picked up by trucks results in fewer trips, which in turn lowers the overall emissions from the waste-management fleet.
Potential sources of compostable materials, or feedstocks, include residential, agricultural, and commercial waste streams. Residential food or yard waste can be composted at home, or collected for inclusion in a large-scale municipal composting facility. In some regions, it could also be included in a local or neighborhood composting project.
The two broad categories of organic solid waste are green and brown. Green waste is generally considered a source of nitrogen and includes pre- and post-consumer food waste, grass clippings, garden trimmings, and fresh leaves. Animal carcasses, roadkill, and butcher residue can also be composted, and these are considered nitrogen sources.
Brown waste is a carbon source. Typical examples are dried vegetation and woody material such as fallen leaves, straw, woodchips, limbs, logs, pine needles, sawdust, and wood ash, but not charcoal ash. Products derived from wood such as paper and plain cardboard are also considered carbon sources.
On many farms, the basic composting ingredients are animal manure generated on the farm as a nitrogen source, and bedding as the carbon source. Straw and sawdust are common bedding materials. Nontraditional bedding materials are also used, including newspaper and chopped cardboard. The amount of manure composted on a livestock farm is often determined by cleaning schedules, land availability, and weather conditions. Each type of manure has its own physical, chemical, and biological characteristics. Cattle and horse manures, when mixed with bedding, possess good qualities for composting. Swine manure, which is very wet and usually not mixed with bedding material, must be mixed with straw or similar raw materials. Poultry manure must be blended with high-carbon, low-nitrogen materials.
Human excreta, sometimes called "humanure" in the composting context, can be added as an input to the composting process since it is a nutrient-rich organic material. Nitrogen, which serves as a building block for important plant amino acids, is found in solid human waste. Phosphorus, which helps plants convert sunlight into energy in the form of ATP, can be found in liquid human waste.
Solid human waste can be collected directly in composting toilets, or indirectly in the form of sewage sludge after it has undergone treatment in a sewage treatment plant. Both processes require capable design, as potential health risks need to be managed. In the case of home composting, a wide range of microorganisms, including bacteria, viruses, and parasitic worms, can be present in feces, and improper processing can pose significant health risks. In the case of large sewage treatment facilities that collect wastewater from a range of residential, commercial and industrial sources, there are additional considerations. The composted sewage sludge, referred to as biosolids, can be contaminated with a variety of metals and pharmaceutical compounds. Insufficient processing of biosolids can also lead to problems when the material is applied to land.
Urine can be put on compost piles or directly used as fertilizer. Adding urine to compost can increase temperatures, so can increase its ability to destroy pathogens and unwanted seeds. Unlike feces, urine does not attract disease-spreading flies (such as houseflies or blowflies), and it does not contain the most hardy of pathogens, such as parasitic worm eggs.
Animal carcasses may be composted as a disposal option. Such material is rich in nitrogen.
Human composting is a process for the final disposition of human remains in which microbes convert a deceased body into compost. It is also called natural organic reduction (NOR) or terramation.
Although the natural decomposition of human corpses into soil is a long-standing practice, a more rapid process that was developed in the early 21st century entails encasing human corpses in wood chips, straw, and alfafa until thermophile microbes decompose the body. In this manner, the transformation can be sped up to as little as 1–2 months. The accelerated process is based in part on techniques developed for the composting of livestock.
In-vessel composting generally describes a group of methods that confine the composting materials within a building, container, or vessel. In-vessel composting systems can consist of metal or plastic tanks or concrete bunkers in which air flow and temperature can be controlled, using the principles of a "bioreactor". Generally the air circulation is metered in via buried tubes that allow fresh air to be injected under pressure, with the exhaust being extracted through a biofilter, with temperature and moisture conditions monitored using probes in the mass to allow maintenance of optimum aerobic decomposition conditions.
Aerated static pile (ASP) composting refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. The blended admixture is usually placed on perforated piping, providing air circulation for controlled aeration. It may be in windrows, open or covered, or in closed containers. With regard to complexity and cost, aerated systems are most commonly used by larger, professionally managed composting facilities, although the technique may range from very small, simple systems to very large, capital intensive, industrial installations.
In agriculture, windrow composting is the production of compost by piling organic matter or biodegradable waste, such as animal manure and crop residues, in long rows – windrow.
The practice of making raised garden beds or mounds filled with rotting wood is also called Hügelkultur in German. It is in effect creating a nurse log that is covered with soil.
Benefits of Hügelkultur garden beds include water retention and warming of soil. Buried wood acts like a sponge as it decomposes, able to capture water and store it for later use by crops planted on top of the bed.
A composting toilet is a type of dry toilet that treats human waste by a biological process called composting. This process leads to the decomposition of organic matter and turns human waste into compost-like material. Composting is carried out by microorganisms (mainly bacteria and fungi) under controlled aerobic conditions. Most composting toilets use no water for flushing and are therefore called "dry toilets".
In many composting toilet designs, a carbon additive such as sawdust, coconut coir, or peat moss is added after each use. This practice creates air pockets in the human waste to promote aerobic decomposition. This also improves the carbon-to-nitrogen ratio and reduces potential odor. Most composting toilet systems rely on mesophilic composting. Longer retention time in the composting chamber also facilitates pathogen die-off. The end product can also be moved to a secondary system – usually another composting step – to allow more time for mesophilic composting to further reduce pathogens.
On open ground for growing wheat, corn, soybeans, and similar crops, compost can be broadcast across the top of the soil using spreader trucks or spreaders pulled behind a tractor. It is expected that the spread layer is very thin (approximately 6 mm (0.24 in)) and worked into the soil prior to planting. Application rates of 25 mm (0.98 in) or more are not unusual when trying to rebuild poor soils or control erosion. Due to the extremely high cost of compost per unit of nutrients in the United States, on-farm use is relatively rare since rates over 4 tons/acre may not be affordable. This results from an over-emphasis on "recycling organic matter" than on "sustainable nutrients." In countries such as Germany, where compost distribution and spreading are partially subsidized in the original waste fees, compost is used more frequently on open ground on the premise of nutrient "sustainability".
In plasticulture, strawberries, tomatoes, peppers, melons, and other fruits and vegetables are grown under plastic to control temperature, retain moisture and control weeds. Compost may be banded (applied in strips along rows) and worked into the soil prior to bedding and planting, be applied at the same time the beds are constructed and plastic laid down, or used as a top dressing.
Many crops are not seeded directly in the field but are started in seed trays in a greenhouse. When the seedlings reach a certain stage of growth, they are transplanted in the field. Compost may be part of the mix used to grow the seedlings, but is not normally used as the only planting substrate. The particular crop and the seeds' sensitivity to nutrients, salts, etc. dictates the ratio of the blend, and maturity is important to insure that oxygen deprivation will not occur or that no lingering phyto-toxins remain.
Compost can be added to soil, coir, or peat, as a tilth improver, supplying humus and nutrients. It provides a rich growing medium as absorbent material. This material contains moisture and soluble minerals, which provide support and nutrients. Although it is rarely used alone, plants can flourish from mixed soil, sand, grit, bark chips, vermiculite, perlite, or clay granules to produce loam. Compost can be tilled directly into the soil or growing medium to boost the level of organic matter and the overall fertility of the soil. Compost that is ready to be used as an additive is dark brown or even black with an earthy smell.
Generally, direct seeding into a compost is not recommended due to the speed with which it may dry, the possible presence of phytotoxins in immature compost that may inhibit germination, and the possible tie up of nitrogen by incompletely decomposed lignin. It is very common to see blends of 20–30% compost used for transplanting seedlings.
Compost can be used to increase plant immunity to diseases and pests.
Compost tea is made up of extracts of fermented water leached from composted materials. Composts can be either aerated or non-aerated depending on its fermentation process. Compost teas are generally produced from adding compost to water in a ratio of 1:4–1:10, occasionally stirring to release microbes.
There is debate about the benefits of aerating the mixture. Non-aerated compost tea is cheaper and less labor intensive, but there are conflicting studies regarding the risks of phytotoxicity and human pathogen regrowth. Aerated compost tea brews faster and generates more microbes, but has potential for human pathogen regrowth.
Field studies have shown the benefits of adding compost teas to crops due to organic matter input, increased nutrient availability, and increased microbial activity. They have also been shown to have a suppressive effect on plant pathogens and soil-borne diseases. The efficacy is influenced by a number of factors, such as the preparation process, the type of source the conditions of the brewing process, and the environment of the crops. Adding nutrients to compost tea can be beneficial for disease suppression, although it can trigger the regrowth of human pathogens like E. coli and Salmonella.
Compost extracts are unfermented or non-brewed extracts of leached compost contents dissolved in any solvent.
Compost is sold as bagged potting mixes in garden centers and other outlets. This may include composted materials such as manure and peat but is also likely to contain loam, fertilizers, sand, grit, etc. Varieties include multi-purpose composts designed for most aspects of planting, John Innes formulations, grow bags, designed to have crops such as tomatoes directly planted into them. There are also a range of specialist composts available, e.g. for vegetables, orchids, houseplants, hanging baskets, roses, ericaceous plants, seedlings, potting on, etc.
Compost can also be used for land and stream reclamation, wetland construction, and landfill cover.
The temperatures generated by compost can be used to heat greenhouses, such as by being placed around the outside edges.
There are process and product guidelines in Europe that date to the early 1980s (Germany, the Netherlands, Switzerland) and only more recently in the UK and the US. In both these countries, private trade associations within the industry have established loose standards, some say as a stop-gap measure to discourage independent government agencies from establishing tougher consumer-friendly standards. Compost is regulated in Canada and Australia as well.
EPA Class A and B guidelines in the United States were developed solely to manage the processing and beneficial reuse of sludge, also now called biosolids, following the US EPA ban of ocean dumping. About 26 American states now require composts to be processed according to these federal protocols for pathogen and vector control, even though the application to non-sludge materials has not been scientifically tested. An example is that green waste composts are used at much higher rates than sludge composts were ever anticipated to be applied at. U.K guidelines also exist regarding compost quality, as well as Canadian, Australian, and the various European states.
In the United States, some compost manufacturers participate in a testing program offered by a private lobbying organization called the U.S. Composting Council. The USCC was originally established in 1991 by Procter & Gamble to promote composting of disposable diapers, following state mandates to ban diapers in landfills, which caused a national uproar. Ultimately the idea of composting diapers was abandoned, partly since it was not proven scientifically to be possible, and mostly because the concept was a marketing stunt in the first place. After this, composting emphasis shifted back to recycling organic wastes previously destined for landfills. There are no bonafide quality standards in America, but the USCC sells a seal called "Seal of Testing Assurance" (also called "STA"). For a considerable fee, the applicant may display the USCC logo on products, agreeing to volunteer to customers a current laboratory analysis that includes parameters such as nutrients, respiration rate, salt content, pH, and limited other indicators.
Many countries such as Wales and some individual cities such as Seattle and San Francisco require food and yard waste to be sorted for composting (San Francisco Mandatory Recycling and Composting Ordinance).
The USA is the only Western country that does not distinguish sludge-source compost from green-composts, and by default 50% of US states expect composts to comply in some manner with the federal EPA 503 rule promulgated in 1984 for sludge products.
There are health risk concerns about PFASs ("forever chemicals") levels in compost derived from sewage sledge sourced biosolids, and EPA has not set health risk standards for this. The Sierra Club recommends that home gardeners avoid the use of sewage sludge-base fertilizer and compost, in part due to potentially high levels of PFASs. The EPA PFAS Strategic Roadmap initiative, running from 2021 to 2024, will consider the full lifecycle of PFAS including health risks of PFAS in wastewater sludge.
Composting dates back to at least the early Roman Empire, and was mentioned as early as Cato the Elder's 160 BCE piece De Agri Cultura. Traditionally, composting involved piling organic materials until the next planting season, at which time the materials would have decayed enough to be ready for use in the soil. The advantage of this method is that little working time or effort is required from the composter and it fits in naturally with agricultural practices in temperate climates. Disadvantages (from the modern perspective) are that space is used for a whole year, some nutrients might be leached due to exposure to rainfall, and disease-producing organisms and insects may not be adequately controlled.
Composting began to modernize somewhat from the 1920s in Europe as a tool for organic farming. The first industrial station for the transformation of urban organic materials into compost was set up in Wels, Austria in the year 1921. Early proponents of composting within farming include Rudolf Steiner, founder of a farming method called biodynamics, and Annie Francé-Harrar, who was appointed on behalf of the government in Mexico and supported the country in 1950–1958 to set up a large humus organization in the fight against erosion and soil degradation. Sir Albert Howard, who worked extensively in India on sustainable practices, and Lady Eve Balfour were also major proponents of composting. Composting was imported to America by the likes of: | [

] | Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes, and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases. At the simplest level, composting requires gathering a mix of "greens" and "browns". Greens are materials rich in nitrogen, such as leaves, grass, and food scraps. Browns are woody materials rich in carbon, such as stalks, paper, and wood chips. The materials break down into humus in a process taking months. Composting can be a multistep, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. The decomposition process is aided by shredding the plant matter, adding water, and ensuring proper aeration by regularly turning the mixture in a process using open piles or "windrows". Fungi, earthworms, and other detritivores further break up the organic material. Aerobic bacteria and fungi manage the chemical process by converting the inputs into heat, carbon dioxide, and ammonium ions. Composting is an important part of waste management, since food and other compostable materials make up about 20% of waste in landfills, and due to anaerobic conditions, these materials take longer to biodegrade in the landfill. Composting offers an environmentally superior alternative to using organic material for landfill because composting reduces methane emissions due to anaerobic conditions, and provides economic and environmental co-benefits. For example, compost can also be used for land and stream reclamation, wetland construction, and landfill cover. | 2001-07-29T04:41:15Z | 2023-09-27T13:04:22Z | [

5,974 | Corundum | Corundum is a crystalline form of aluminium oxide (Al2O3) typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire. Rubies are red due to the presence of chromium, and sapphires exhibit a range of colors depending on what transition metal is present. A rare type of sapphire, padparadscha sapphire, is pink-orange.
The name "corundum" is derived from the Tamil-Dravidian word kurundam (ruby-sapphire) (appearing in Sanskrit as kuruvinda).
Because of corundum's hardness (pure corundum is defined to have 9.0 on the Mohs scale), it can scratch almost all other minerals. It is commonly used as an abrasive on sandpaper and on large tools used in machining metals, plastics, and wood. Emery, a variety of corundum with no value as a gemstone, is commonly used as an abrasive. It is a black granular form of corundum, in which the mineral is intimately mixed with magnetite, hematite, or hercynite.
In addition to its hardness, corundum has a density of 4.02 g/cm (251 lb/cu ft), which is unusually high for a transparent mineral composed of the low-atomic mass elements aluminium and oxygen.
Corundum occurs as a mineral in mica schist, gneiss, and some marbles in metamorphic terranes. It also occurs in low-silica igneous syenite and nepheline syenite intrusives. Other occurrences are as masses adjacent to ultramafic intrusives, associated with lamprophyre dikes and as large crystals in pegmatites. It commonly occurs as a detrital mineral in stream and beach sands because of its hardness and resistance to weathering. The largest documented single crystal of corundum measured about 65 cm × 40 cm × 40 cm (26 in × 16 in × 16 in), and weighed 152 kg (335 lb). The record has since been surpassed by certain synthetic boules.
Corundum for abrasives is mined in Zimbabwe, Pakistan, Afghanistan, Russia, Sri Lanka, and India. Historically it was mined from deposits associated with dunites in North Carolina, US, and from a nepheline syenite in Craigmont, Ontario. Emery-grade corundum is found on the Greek island of Naxos and near Peekskill, New York, US. Abrasive corundum is synthetically manufactured from bauxite.
Four corundum axes dating to 2500 BC from the Liangzhou culture have been discovered in China.
The Verneuil process allows the production of flawless single-crystal sapphire and ruby gems of much larger size than normally found in nature. It is also possible to grow gem-quality synthetic corundum by flux-growth and hydrothermal synthesis. Because of the simplicity of the methods involved in corundum synthesis, large quantities of these crystals have become available on the market at a fraction of the cost of natural stones.
Apart from ornamental uses, synthetic corundum is also used to produce mechanical parts (tubes, rods, bearings, and other machined parts), scratch-resistant optics, scratch-resistant watch crystals, instrument windows for satellites and spacecraft (because of its transparency in the ultraviolet to infrared range), and laser components. For example, the KAGRA gravitational wave detector's main mirrors are 23 kg (50 lb) sapphires, and Advanced LIGO considered 40 kg (88 lb) sapphire mirrors. Corundum has also found use in the development of ceramic armour thanks to its high hardiness.
Corundum crystallizes with trigonal symmetry in the space group R3c and has the lattice parameters a = 4.75 Å and c = 12.982 Å at standard conditions. The unit cell contains six formula units.
The toughness of corundum is sensitive to surface roughness and crystallographic orientation. It may be 6–7 MPa·m for synthetic crystals, and around 4 MPa·m for natural.
In the lattice of corundum, the oxygen atoms form a slightly distorted hexagonal close packing, in which two-thirds of the octahedral sites between the oxygen ions are occupied by aluminium ions. The absence of aluminium ions from one of the three sites breaks the symmetry of the hexagonal close packing, reducing the space group symmetry to R3c and the crystal class to trigonal. The structure of corundum is sometimes described as a pseudohexagonal structure.
Because of its prevalence, corundum has also become the name of a major structure type (corundum type) found in various binary and ternary compounds. | [

] | Corundum is a crystalline form of aluminium oxide (Al2O3) typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire. Rubies are red due to the presence of chromium, and sapphires exhibit a range of colors depending on what transition metal is present. A rare type of sapphire, padparadscha sapphire, is pink-orange. The name "corundum" is derived from the Tamil-Dravidian word kurundam (ruby-sapphire). Because of corundum's hardness, it can scratch almost all other minerals. It is commonly used as an abrasive on sandpaper and on large tools used in machining metals, plastics, and wood. Emery, a variety of corundum with no value as a gemstone, is commonly used as an abrasive. It is a black granular form of corundum, in which the mineral is intimately mixed with magnetite, hematite, or hercynite. In addition to its hardness, corundum has a density of 4.02 g/cm3 (251 lb/cu ft), which is unusually high for a transparent mineral composed of the low-atomic mass elements aluminium and oxygen. | 2001-11-06T02:03:56Z | 2023-10-13T11:18:52Z | [

5,976 | Capoeira | Capoeira (Portuguese pronunciation: [kapuˈe(j)ɾɐ]) is an Afro-Brazilian martial art and game that includes elements of dance, acrobatics, music and spirituality.
It is known for its acrobatic and complex maneuvers, often involving hands on the ground and inverted kicks. It emphasizes flowing movements rather than fixed stances; the ginga, a rocking step, is usually the focal point of the technique. Though often said to be a martial art disguised as a dance, capoeira served not only as a form of self defense, but also as a way to maintain spirituality and culture.
Capoeira has been played among Black Brazilians for centuries. The date of its creation is unknown, but it was first mentioned in a judicial document under the name capoeiragem in 1789, as "the gravest of crimes". In the 19th century, the street fighting style called capoeira carioca was developed. It was repeatedly outlawed and its performers persecuted, and it was declared totally illegal and banned in 1890. In the early 1930s, Mestre Bimba reformed traditional capoeira and incorporated elements of jiu jitsu, gymnastics and sports. In doing so, the government viewed capoeira as a socially acceptable sport. in 1941, Mestre Pastinha Later founded his school where he cultivated the traditional capoeira Angola, distinguishing it from reformed capoeira as the Brazilians' national sport.
In the late 1970s, trailblazers such as Mestre Acordeon started bringing capoeira to the US and Europe, helping the art become internationally recognized and practiced. On 26 November 2014, capoeira was granted a special protected status as intangible cultural heritage by UNESCO.
Martial arts from the African diaspora similar to capoeira include knocking and kicking from the Sea Islands, and ladya from Martinique, both of which likely originate from engolo.
In the past, many participants used the name angola or the term brincar de angola ("playing angola") for this art. In police documents, capoeira was known as capoeiragem, with a practitioner being called capoeira. Gradually, the art became known as capoeira with a practitioner being called a capoeirista. In a narrower sense, capoeiragem meant a set of fighting skills. The term jogo de capoeira (capoeira game) is used to describe the art in the performative context.
Although debated, the most widely accepted origin of the word capoeira comes from the Tupi words ka'a ("forest") paũ ("round"), referring to the areas of low vegetation in the Brazilian interior where fugitive slaves would hide.
Well, there is one thing that nobody doubts: the ones to teach capoeira to us were the negro slaves that were brought from Angola.
In the past, some participants used the name angola or the term brincar de angola ("playing angola") for this art. In formal documents, capoeira was known as "capoeiragem", with a practitioner being known as a "capoeira". Gradually, the art became known as capoeira with a practitioner being called a capoeirista.
Capoeira first appeared among Africans in Brazil, during the early colonial period. According to the old capoeira mestres and tradition within the community, capoeira originates from Angola. Although the origin of capoeira is not entirely clear, many studies have supported the oral tradition, identifying engolo as an ancestral art and locating the Cunene region as its birthplace. Still, some authors believe there were more ancestors besides engolo. However, at the core of capoeira we find techniques developed in engolo, including crescent kicks, push kicks, sweeps, handstands, cartwheels, evasions and even the iconic Meia lua de compasso, scorpion kick and L-kick.
The street capoeira in 19th-century Rio was very violent and far from the original art. This street-fighting capoeiragem was mix of five fighting techniques: foot kicks, head butts, hand blows, knife fight and stick-fighting, only the first of them arguably originates from Angolan art. That now extinct version of capoeira was called capoeira carioca (meaning of Rio de Janeiro).
Modern capoeira comes from Bahia, and was codified by mestre Bimba and mestre Pastinha, in regional and angola style. Despite their significant differences, both mestres introduced major innovations — they moved training and rodas away from the street, instituted the academia, prescribed uniforms, started to teach women and presented capoeira to a broader audiences.
Capoeira is a fast and versatile martial art that is historically focused on fighting when outnumbered or at a technological disadvantage. The style emphasizes using the lower body to kick, sweep and take down their aggressors, using the upper body to assist those movements and occasionally attack as well. It features a series of complex positions and body postures that are meant to get chained in an uninterrupted flow, to strike, dodge and move without breaking motion, conferring the style with a characteristic unpredictability and versatility.
The ginga (literally: rocking back and forth; to swing) is the fundamental movement in capoeira, important both for attack and defense purposes. It has two main objectives. One is to keep the capoeirista in a state of constant motion, preventing them from being a still and easy target. The other, using also fakes and feints, is to mislead, fool or trick the opponent, leaving them open for an attack or a counter-attack.
The attacks in the capoeira should be done when opportunity arises, and though they can be preceded by feints or pokes, they must be precise and decisive, like a direct kick to the head, face or a vital body part, or a strong takedown. Most capoeira attacks are made with the legs, like direct or swirling kicks, rasteiras (leg sweeps), tesouras or knee strikes. Elbow strikes, punches and other forms of takedowns complete the main list. The head strike is a very important counter-attack move.
The defense is based on the principle of non-resistance, meaning avoiding an attack using evasive moves instead of blocking it. Avoids are called esquivas, which depend on the direction of the attack and intention of the defender, and can be done standing or with a hand leaning on the floor. A block should only be made when the esquiva is completely non-viable. This fighting strategy allows quick and unpredictable counterattacks, the ability to focus on more than one adversary and to face empty-handed an armed adversary.
A series of rolls and acrobatics (like the cartwheels called aú or the transitional position called negativa) allows the capoeirista to quickly overcome a takedown or a loss of balance, and to position themselves around the aggressor to lay up for an attack. It is this combination of attacks, defense and mobility that gives capoeira its perceived "fluidity" and choreography-like style.
Through most of its history in Brazil, capoeira commonly featured weapons and weapon training, given its street fighting nature. Capoeiristas usually carried knives and bladed weapons with them, and the berimbau could be used to conceal those inside, or even to turn itself into a weapon by attaching a blade to its tip. The knife or razor was used in street rodas and/or against openly hostile opponents, and would be drawn quickly to stab or slash. Other hiding places for the weapons included hats and umbrellas.
Mestre Bimba included in his teachings a curso de especialização or "specialization course", in which the pupils would be taught defenses against knives and guns, as well as the usage of knife, straight razor, scythe, club, chanfolo (double-edged dagger), facão (facón or machete) and tira-teima (cane sword). Upon graduating, pupils were given a red scarf which marked their specialty. This course was scarcely used, and was ceased after some time. A more common custom practised by Bimba and his students, however, was furtively handing a weapon to a player before a jogo for them to use it to attack their opponent on Bimba's sign, with the other player's duty being to disarm them.
This weapon training is almost completely absent in current capoeira teachings, but some groups still practice the use of razors for ceremonial usage in the rodas.
In Bantu culture, the Nkhumbi term ochimama encapsulates the overlapping meanings of game, dance, and tradition. This overlap is also found in Afro-Brazilian folklore, where many similar forms of expression are called brincadeiras (games). Some scholars have interpreted capoeira as a way of concealing martial arts within dance movements. However, research from Angola suggests that the relationship between game, fight, and dance may be even deeper. These scholars propose that the ambivalence between these three elements is a fundamental aspect of the ancestral grammar shared by engolo and capoeira.
Playing capoeira is both a game and a method of practicing the application of capoeira movements in simulated combat. It can be played anywhere, but it's usually done in a roda. During the game most capoeira moves are used, but capoeiristas usually avoid punches or elbow strikes unless it's a very aggressive game. The game does not focus on knocking down or defeating opponents, but rather on body dialogue and highlighting skills.
The roda (pronounced [ˈʁodɐ]) is a circle formed by capoeiristas and capoeira musical instruments, where every participant sings the typical songs and claps their hands following the music. Two capoeiristas enter the roda and play the game according to the style required by the musical rhythm. The game finishes when one of the musicians holding a berimbau determines it, when one of the capoeiristas decides to leave or call the end of the game, or when another capoeirista interrupts the game to start playing, either with one of the current players or with another capoeirista.
In a roda every cultural aspect of capoeira is present, not only the martial side. Aerial acrobatics are common in a presentation roda, while not seen as often in a more serious one. Takedowns, on the other hand, are common in a serious roda but rarely seen in presentations.
The batizado (lit. baptism) is a ceremonial roda where new students will get recognized as capoeiristas and earn their first graduation. Also more experienced students may go up in rank, depending on their skills and capoeira culture. In Mestre Bimba's Capoeira Regional, batizado was the first time a new student would play capoeira following the sound of the berimbau.
Students enter the roda against a high-ranked capoeirista (such as a teacher or master) and normally the game ends with the student being taken down. In some cases the more experienced capoeirista can judge the takedown unnecessary. Following the batizado the new graduation, generally in the form of a cord, is given.
Traditionally, the batizado is the moment when the new practitioner gets or formalizes their apelido (nickname). This tradition was created back when capoeira practice was considered a crime. To avoid having problems with the law, capoeiristas would present themselves in the capoeira community only by their nicknames.
Chamada means 'call' and can happen at any time during a roda where the rhythm angola is being played. It happens when one player, usually the more advanced one, calls their opponent to a dance-like ritual. The opponent then approaches the caller and meets them to walk side by side. After it both resume normal play.
While it may seem like a break time or a dance, the chamada is actually both a trap and a test, as the caller is just watching to see if the opponent will let his guard down so she can perform a takedown or a strike. It is a critical situation, because both players are vulnerable due to the close proximity and potential for a surprise attack. It's also a tool for experienced practitioners and masters of the art to test a student's awareness and demonstrate when the student left herself open to attack.
The use of the chamada can result in a highly developed sense of awareness and helps practitioners learn the subtleties of anticipating another person's hidden intentions. The chamada can be very simple, consisting solely of the basic elements, or the ritual can be quite elaborate including a competitive dialogue of trickery, or even theatric embellishments.
Volta ao mundo means around the world.
The volta ao mundo takes place after an exchange of movements has reached a conclusion, or after there has been a disruption in the harmony of the game. In either of these situations, one player will begin walking around the perimeter of the circle counter-clockwise, and the other player will join the volta ao mundo in the opposite part of the roda, before returning to the normal game.
Music is integral to capoeira. It sets the tempo and style of game that is to be played within the roda. Typically the music is formed by instruments and singing. Rhythms (toques), controlled by a typical instrument called berimbau, differ from very slow to very fast, depending on the style of the roda.
Capoeira instruments are disposed in a row called bateria. It is traditionally formed by three berimbaus, two pandeiros, three atabaques, one agogô and one ganzá, but this format may vary depending on the capoeira group's traditions or the roda style.
The berimbau is the leading instrument, determining the tempo and style of the music and game played. Two low-pitch berimbaus (called berra-boi and médio) form the base and a high-pitch berimbau (called viola) makes variations and improvisations. The other instruments must follow the berimbau's rhythm, free to vary and improvise a little, depending upon the capoeira group's musical style.
As the capoeiristas change their playing style significantly following the toque of the berimbau, which sets the game's speed, style and aggressiveness, it is truly the music that drives a capoeira game.
Many of the songs are sung in a call and response format while others are in the form of a narrative. Capoeiristas sing about a wide variety of subjects. Some songs are about history or stories of famous capoeiristas. Other songs attempt to inspire players to play better. Some songs are about what is going on within the roda. Sometimes the songs are about life or love lost. Others have lighthearted and playful lyrics.
There are four basic kinds of songs in capoeira, the Ladaínha, Chula, Corrido and Quadra. The Ladaínha is a narrative solo sung only at the beginning of a roda, often by a mestre (master) or most respected capoeirista present. The solo is followed by a louvação, a call and response pattern that usually thanks God and one's master, among other things. Each call is usually repeated word-for-word by the responders. The Chula is a song where the singer part is much bigger than the chorus response, usually eight singer verses for one chorus response, but the proportion may vary. The Corrido is a song where the singer part and the chorus response are equal, normally two verses by two responses. Finally, the Quadra is a song where the same verse is repeated four times, either three singer verses followed by one chorus response, or one verse and one response.
Capoeira songs can talk about virtually anything, being it about a historical fact, a famous capoeirista, trivial life facts, hidden messages for players, anything. Improvisation is very important also, while singing a song the main singer can change the music's lyrics, telling something that's happening in or outside the roda.
The capoeirista resorts to an endless number of tricks to confuse and distract his opponent. He pretends to step back but he returns quickly; jumps from side to side; lies down and gets up; advances and retreats; pretends not to see the opponent to deceive him; turns in all directions; and shrinks in a cunning and bewildering ginga.
The basic term of capoeira philosophy is malícia (malice). One aspect of malicia consists of deceiving the opponent into thinking that you are going to execute a certain move when in fact you are going to do something completely different. There is an example of malicia of Besouro who once fell to the ground during a game, crying like a woman and begging for mercy. Mestre João Pequeno claimed that he teaches his students how to play capoeira, but they should learn malícia for themselves since it cannot be taught.
The meaning of malícia in capoeira has expanded over time to cunning, suspicion, alertness, readiness, flexibility, and adaptation. Basically, it is the capacity to understand someone's intentions and making use of this understanding to misdirect someone as to your next move. In the contemporary capoeira, this is done good-naturedly, contrary to what the word may suggest. Nestor Capoeira explicated malícia as follows:
I think malícia is not only to feign, to pretend that you are going to deliver a certain blow and do something else, but a system of signs and signals. It is as if you were casting a spell or a charm in order to build a specific reality, a seductive reality, during the game and also outside the roda in day-to-day life and in any type of struggle or combat.
Gregory Downey explains:
Malícia, not coincidentally, is the quality, or constellation of qualities, that the ideal capoeirista should most evidence in his or her everyday life: a combination of wariness, quick wit, savvy, unpredictability, opportunism, playfulness, viciousness, and a talent for deception. The ability to fool, distract, and deceive the opponent is the key to success. The basic movement in capoeira, the ginga, is a constant fluid movement backward and forward, and a good capoeirista will use malícia in the ginga to deceive his opponent.
The ginga is the first principle of capoeira and the embodiment of malice. The continuous, ceaseless bodily motion, known as gingar, is the principle that creates deception or trickery, catching the opponent off guard.
The bênção kick, ironically named, reflects another form of malícia. Slave owners would gather slaves in the morning, often on Sundays, to offer blessings, despite their mistreatment. In a deceptive twist, bênção appears as a blessing but swiftly becomes an attack on the opponent's belly.
Malandragem is a word that comes from malandro, a men who used street smarts to make a living. In the 19th century, capoeira was quite similar to the type of urban person who was a constant source of trouble — the malandro (punk).
In the 19th century Rio de Janeiro, the capoeirista was a malandro (a rogue) and a criminal, expert in the use of kicks (golpes), sweeps (rasteiras) and head-butts (cabecadas), as well in the use of blade weapons.
In capoeira, malandragem is the ability to quickly understand an opponent's intentions, and during a fight or a game, fool, trick and deceive him.
A popular Brazilian saying, "Malandro demais se atrapalha" means that when one tries to be too clever or smart, instead of confusing his opponent, he confuses himself.
Spirituality in capoeira is shaped under the influence of various African beliefs. Some important concepts of candomblé, such as dendé and axé, which refer to different conceptions of energy, have become common among capoeiristas.
Dr Maya Talmon-Chvaicer suggests that capoeira should be explained in Bantu terms. For the African slaves, capoeira was a social expression that incorporated all the basic African elements: circle, dance, music, rituals and symbols. It also contains all the ingredients of a game from the Kongolese perspective: a means to train and prepare for life, providing the experience needed to strengthen the body and the soul.
Within the Bantu culture, the circle carries profound symbolism. Dancing in a circle holds significance, representing protection and strength, symbolizing the bond with the spirit world, life, and the divine.
A major means of communication with the ancestors is music. Musical instruments play a pivotal role in bridging the realms of the living, the deceased, and the gods. This explains why African dances customarily commence by paying homage to the primary instrument, often through kneeling or bowing before it. This practice of appeasement and seeking divine assistance from the gods is mirrored in the capoeira tradition of kneeling before the berimbau during the ladainha.
African martial arts naturally take the form of dance. In Bantu culture, dance is an integral part of daily life, encompassing song, music, movements, and rituals. This holistic view applies to Congo/Angola, where dance is intricately linked to song, music, and ritual.
In Bantu religion, kalûnga represents the idea that, in the realm of the living everything is reversed from the realm of the ancestors. Where men walk on their feet, the spirits walk on their hands; where men reach their peak physical abilities, the ancestors reach their peak spirituality. Inhabitants of the ancestral realm are inverted compared to us, as viewed from our mirrored perspective. With this particular worldview, practitioners of African martial arts deliberately invert themselves upside down to emulate the ancestors, and to draw strength and power from the ancestral realm.
One of the capoeira ritual is performing the "au" at the beginning of the game. This act symbolizes a profound transition in Kongolese religion, where touching the ground with hands while feet are up in the air signifies the player crosses over to other worlds.
Capoeira has been additionally shaped by the cosmic worldview of candomblé, an Afro-Brazilian religion that has engaged with various manifestations of natural energies. The capoeira player in past usually had his orixá or santo (patron saint) as Ogum (the Warrior) or Oxóssi (the Hunter).
Capoeira is slave mandinga, desirous of freedom.
Its principles have no method,
its aim is inconceivable even to the wisest of the mestres.
Capoeira holds a core of mandinga, which can be translated as a magic, sorcery, witchcraft. Mandinga suggests an understanding of fundamental natural forces and their utilization through magic rituals to some extent. In the past, capoeiristas used protective amulets and performed specific rituals to ensure their safety. Same players "do their mandinga" before the game by drawing magical symbols on the ground with their fingers.
Some magic elements in capoeira are clear and familiar, while others have become obscure over time. Folklorist Edison Carneiro noted that the ladainha, sung before entering the capoeira circle, invokes the gods, adding a touch of mysticism to the ritual. Actions like touching the ground symbolize drawing signs in the dust, and gestures such as kissing hands, crossing oneself, and prayer are reminders of long-forgotten traditions, the Bantus' prayer for divine blessings, aid, and bravery in battle.
Mandinga is also a certain esthetic, where the game is expressive and sometimes theatrical, especially in the Angola style. An advanced capoeira player is sometimes referred to as a mandingueiro, someone who embodies mandinga.
The roots of the term mandingueiro would be a person who had the magic ability to avoid harm due to protection from the Orixás. Alternately the word mandinga originates from the name of Mandinka people.
It is a task, and a lonely one, to find and develop your own style, breaking with the “correct” way of playing that you learned from your teacher, who many times presents himself as “owner of the truth.” But this can be done after one has experience and an idea of what capoeira is … maybe after ten or fifteen years of practice.
Determining styles in capoeira is difficult, since there was never a unity in the original capoeira, or a teaching method before the decade of 1920. However, a division between two styles and a sub-style is widely accepted.
Capoeira de Angola (Angolan capoeira) is the traditional style of capoeira. However, it can refer to two things:
The ideal of capoeira Angola is to maintain capoeira as close to its roots as possible. Although Pastinha strove to preserve the original Angolan art, he nevertheless introduced significant changes to capoeira practice of his time. He forbid weapon and violent moves, prescribed uniforms, moved training away from the street into the academia, and started to teach women.
Capoeira Angola is characterized by being strategic, with sneaking movements executed standing or near the floor depending on the situation to face, it values the traditions of malícia, malandragem and unpredictability of the original capoeira. The anthropologist Alejandro Frigerio defines capoeira Angola as art, versus capoeira Regional as sport. He emphasizes the following characteristics of contemporary capoeira Angola, namely: cunning, complementation (of the two players" movements), a low game, the absence of violence, beautiful movements (according to a "black aesthetic"), slow music and the importance of ritual and theatricality.
Unlike many other capoeira groups that play barefoot, angoleiros always train with shoes. When it comes to the color of the uniforms, there is a lack of uniformity within the style. Although mestre Pastinha at his academy required students to wear yellow and black jerseys, some of his successors have adopted white only uniforms within their schools.
Capoeira Regional began to take form in the 1920s, when Mestre Bimba met his future student, José Cisnando Lima. Both believed that capoeira was losing its martial side and concluded there was a need to re-strengthen and structure it. Bimba created his sequências de ensino (teaching combinations) and created capoeira's first teaching method. Advised by Cisnando, Bimba decided to call his style Luta Regional Baiana, as capoeira was still illegal at that time.
The base of capoeira regional is the original capoeira without many of the aspects that were impractical in a real fight, with less subterfuge and more objectivity. Training focuses mainly on attack, dodging and counter-attack, giving high importance to precision and discipline. Bimba also added a few moves from other arts, notably the batuque, an old street fight game invented by his father. Use of jumps or aerial acrobatics stay to a minimum, since one of its foundations is always keeping at least one hand or foot firmly attached to the ground.
Capoeira Regional also introduced the first ranking method in capoeira. Regional had three levels: calouro (freshman), formado (graduated) and formado especializado (specialist). After 1964, when a student completed a course, a special celebration ceremony occurred, ending with the teacher tying a silk scarf around the capoeirista's neck.
The traditions of roda and capoeira game were kept, being used to put into use what was learned during training. The disposition of musical instruments, however, was changed, being made by a single berimbau and two pandeiros.
The Luta Regional Baiana soon became popular, finally changing capoeira's bad image. Mestre Bimba made many presentations of his new style, but the best known was the one made at 1953 to Brazilian president Getúlio Vargas, where the president would say: "A Capoeira é o único esporte verdadeiramente nacional" (Capoeira is the only truly national sport).
Capoeira carioca was a street fighting version of capoeira that existed in Rio de Janeiro during the 19th century, used by gangs. In capoeira carioca, all available means were used, including various types of weapons, such as knives, straight razors, clubs and machetes. Capoeira from this period is also known as capoeiragem. The widespread violent capoeira practice in Rio led to a nationwide ban on capoeira. After the ban in 1890 and the subsequent mass arrests of capoeira gang members, this version of capoeira is generally extinct.
The main reformators and proponents of this fighting-oriented capoeira were Mestre Sinhozinho and Mestre Zuma.
Capoeira flourished in the city of São Paulo since the 1960s. Mestre Suassuna was prominent figure throughout this period. Mestre Canjiquinha played important role in shaping the capoeira style that began to emerge in São Paulo during the 1960s. This evolving style, which emerged in the 1960s and 1970s, drew from both Regional and Angola styles while maintaining its distinct characteristics. The majority of modern practitioners affirm to be neither Angola nor Regional, emphasizing that "there is only one capoeira".
This new capoeira incorporated not only berimbaus and pandeiros but also atabaque and agogô into its musical ensemble. In contrast to Bimba's preference for quadras, these modern rodas typically commenced with ladainhas. The games in these rodas often featured a fast and upright style, even though they might start with an Angola toque and a slower game.
Nowadays the label Contemporânea applies to any capoeira group who don't follow Regional or Angola styles, even the ones who mix capoeira with other martial arts. Some notable groups whose style cannot be described as either Angola or Regional but rather "a style of their own", include Senzala de Santos, Cordão de Ouro and Abada. In the case of Cordão de Ouro, the style may be described as "Miudinho", a low and fast-paced game, while in Senzala de Santos the style may described simply as "Senzala de Santos", an elegant, playful combination of Angola and Regional.
Because of its origin, capoeira never had unity or a general agreement. Ranking or graduating system follows the same path, as there never existed a ranking system accepted by most of the masters. That means graduation style varies depending on the group's traditions. The most common modern system uses colored ropes, called corda or cordão, tied around the waist. Some masters use different systems, or even no system at all. In a substantial number of groups (mainly of the Angola school) there is no visible ranking system. There can still be several ranks: student, treinel, professor, contra-mestre and mestre, but often no cordas (belts).
There are many entities (leagues, federations and association) with their own graduation system. The most usual is the system of the Confederação Brasileira de Capoeira (Brazilian Capoeira Confederation), which adopts ropes using the colors of the Brazilian flag, green, yellow, blue and white. However, the Confederação Brasileira de Capoeira is not widely accepted as the capoeira's main representative.

Even though those activities are strongly associated with capoeira, they have different meanings and origins.
Performed by many capoeira groups, samba de roda is a traditional Brazilian dance and musical form that has been associated with capoeira for many decades. The orchestra is composed by pandeiro, atabaque, berimbau-viola (high pitch berimbau), chocalho, accompanied by singing and clapping. Samba de roda is considered one of the primitive forms of modern Samba.
Originally the Maculelê is believed to have been an indigenous armed fighting style, using two sticks or a machete. Nowadays it's a folkloric dance practiced with heavy Brazilian percussion. Many capoeira groups include Maculelê in their presentations.
Puxada de Rede is a Brazilian folkloric theatrical play, seen in many capoeira performances. It is based on a traditional Brazilian legend involving the loss of a fisherman in a seafaring accident.
I think beating (pancadaria) is good. I learned capoeira being beaten up and I like a rough game, heavy game. Sometimes, when I receive a kick that breaks my mouth, my nose, I even like it because I am learning. Beating is important in capoeira. Pancadaria is not violence.
Combat capoeira, often referred to as rough capoeira (capoeira dura), places a primary emphasis on combat. It is commonly observed in ring competitions and street rodas, and sometimes even in graduations within certain groups.
Several capoeira fighters have gained national reputation, including Mestre King Kong from Salvador, Mestre Maurão from São Paulo, and King from Rio de Janeiro (formerly associated with Abadá). They advocate for capoeiristas to be skilled in playing intense games to ensure that the art retains its combat effectiveness.
It's important to note that capoeira fights have, on occasion, resulted in severe injuries and even fatalities, as seen in Petrópolis in 1996. The most suitable context for combat-focused capoeira appears to be the ring, where predetermined fighting rules provide clarity. In the tradition of Ciriaco, Sinhozinho, Bimba, and Arthur Emídio, contemporary capoeira fighters have expanded their training by incorporating various martial arts disciplines, including ju-jitsu, boxing, and taekwondo.
Even Brazilian mixed martial arts champions like Marco Ruas acknowledge the significance of capoeira in their training. The use of capoeira techniques in free-style competitions shows to what extent the art still provides essential fighting skills. | [

] | Capoeira is an Afro-Brazilian martial art and game that includes elements of dance, acrobatics, music and spirituality. It is known for its acrobatic and complex maneuvers, often involving hands on the ground and inverted kicks. It emphasizes flowing movements rather than fixed stances; the ginga, a rocking step, is usually the focal point of the technique. Though often said to be a martial art disguised as a dance, capoeira served not only as a form of self defense, but also as a way to maintain spirituality and culture. Capoeira has been played among Black Brazilians for centuries. The date of its creation is unknown, but it was first mentioned in a judicial document under the name capoeiragem in 1789, as "the gravest of crimes". In the 19th century, the street fighting style called capoeira carioca was developed. It was repeatedly outlawed and its performers persecuted, and it was declared totally illegal and banned in 1890. In the early 1930s, Mestre Bimba reformed traditional capoeira and incorporated elements of jiu jitsu, gymnastics and sports. In doing so, the government viewed capoeira as a socially acceptable sport. in 1941, Mestre Pastinha Later founded his school where he cultivated the traditional capoeira Angola, distinguishing it from reformed capoeira as the Brazilians' national sport. In the late 1970s, trailblazers such as Mestre Acordeon started bringing capoeira to the US and Europe, helping the art become internationally recognized and practiced. On 26 November 2014, capoeira was granted a special protected status as intangible cultural heritage by UNESCO. Martial arts from the African diaspora similar to capoeira include knocking and kicking from the Sea Islands, and ladya from Martinique, both of which likely originate from engolo. | 2001-07-30T01:47:42Z | 2023-12-17T15:29:33Z | [

5,980 | Carbon sink | A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide (CO2) from the atmosphere. These sinks form an important part of the natural carbon cycle. An overarching term is carbon pool, which is all the places where carbon can be (the atmosphere, oceans, soil, plants, and so forth). A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases.
Globally, the two most important carbon sinks are vegetation and the ocean. Soil is an important carbon storage medium. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming. "Blue carbon" designates carbon that is fixed via the ocean ecosystems. Coastal blue carbon includes mangroves, salt marshes and seagrasses which make up a majority of ocean plant life and store large quantities of carbon. Deep blue carbon is located in the high seas beyond national jurisdictions and includes carbon contained in "continental shelf waters, deep-sea waters and the sea floor beneath them. As a main carbon sink, the ocean removes excess greenhouse gas emissions such as heat and energy."
Many efforts are being made to enhance natural carbon sinks, mainly soils and forests, to mitigate climate change. These efforts counter historical trends caused by practices like deforestation and industrial agriculture which depleted natural carbon sinks; land use, land-use change, and forestry historically have been important human contributions to climate change. In addition to enhancing natural processes, investments in artificial sequestration initiatives are underway to store carbon in building materials or deep underground.
In the context of climate change and in particular mitigation, a sink is defined as "Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere".
In the case of non-CO2 greenhouse gases, sinks need not store the gas. Instead they can break it down into substances that have a reduced effect on global warming. For example, nitrous oxide can be reduced to harmless N2.
Related terms are "carbon pool, reservoir, sequestration, source and uptake". The same publication defines carbon pool as "a reservoir in the Earth system where elements, such as carbon [...], reside in various chemical forms for a period of time."
Both carbon pools and carbon sinks are important concepts in understanding the carbon cycle, but they refer to slightly different things. A carbon pool can be thought of as the overarching term, and carbon sink is then a particular type of carbon pool: A carbon pool is all the places where carbon can be (for example the atmosphere, oceans, soil, plants, and fossil fuels). A carbon sink, on the other hand, is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases.
The amount of carbon dioxide varies naturally in a dynamic equilibrium with photosynthesis of land plants. The natural carbon sinks are:
Artificial carbon sinks are those that store carbon in building materials or deep underground (geologic carbon sequestration). No major artificial systems remove carbon from the atmosphere on a large scale yet.
Public awareness of the significance of CO2 sinks has grown since passage of the 1997 Kyoto Protocol, which promotes their use as a form of carbon offset.
Soils represent a short to long-term carbon storage medium, and contain more carbon than all terrestrial vegetation and the atmosphere combined. Plant litter and other biomass including charcoal accumulates as organic matter in soils, and is degraded by chemical weathering and biological degradation. More recalcitrant organic carbon polymers such as cellulose, hemi-cellulose, lignin, aliphatic compounds, waxes and terpenoids are collectively retained as humus.
Organic matter tends to accumulate in litter and soils of colder regions such as the boreal forests of North America and the Taiga of Russia. Leaf litter and humus are rapidly oxidized and poorly retained in sub-tropical and tropical climate conditions due to high temperatures and extensive leaching by rainfall. Areas where shifting cultivation or slash and burn agriculture are practiced are generally only fertile for two to three years before they are abandoned. These tropical jungles are similar to coral reefs in that they are highly efficient at conserving and circulating necessary nutrients, which explains their lushness in a nutrient desert.
Grasslands contribute to soil organic matter, stored mainly in their extensive fibrous root mats. Due in part to the climatic conditions of these regions (e.g. cooler temperatures and semi-arid to arid conditions), these soils can accumulate significant quantities of organic matter. This can vary based on rainfall, the length of the winter season, and the frequency of naturally occurring lightning-induced grass-fires. While these fires release carbon dioxide, they improve the quality of the grasslands overall, in turn increasing the amount of carbon retained in the humic material. They also deposit carbon directly to the soil in the form of biochar that does not significantly degrade back to carbon dioxide.
Organic matter in peat bogs undergoes slow anaerobic decomposition below the surface. This process is slow enough that in many cases the bog grows rapidly and fixes more carbon from the atmosphere than is released. Over time, the peat grows deeper. Peat bogs hold approximately one-quarter of the carbon stored in land plants and soils.
Much organic carbon retained in many agricultural areas worldwide has been severely depleted due to intensive farming practices. Since the 1850s, a large proportion of the world's grasslands have been tilled and converted to croplands, allowing the rapid oxidation of large quantities of soil organic carbon. Methods that significantly enhance carbon sequestration in soil include no-till farming, residue mulching, cover cropping, and crop rotation, all of which are more widely used in organic farming than in conventional farming.
Forests are generally carbon dioxide sinks when they are high in diversity, density or area. However, they can also be carbon sources if diversity, density or area decreases due to deforestation, selective logging, climate change, wildfires or diseases. One study in 2020 found that 32 tracked Brazilian non-Amazon seasonal tropical forests declined from a carbon sink to a carbon source in 2013 and concludes that "policies are needed to mitigate the emission of greenhouse gases and to restore and protect tropical seasonal forests". In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts and deforestation. The typical tropical forest may become a carbon source by the 2060s.
FAO reported that: "The total carbon stock in forests decreased from 668 gigatonnes in 1990 to 662 gigatonnes in 2020". However, another study finds that the leaf area index has increased globally since 1981, which was responsible for 12.4% of the accumulated terrestrial carbon sink from 1981 to 2016. The CO2 fertilization effect, on the other hand, was responsible for 47% of the sink, while climate change reduced the sink by 28.6%. In Canada's boreal forests as much as 80% of the total carbon is stored in the soils as dead organic matter.
Carbon offset programs are planting millions of fast-growing trees per year to reforest tropical lands, for as little as $0.10 per tree; over their typical 40-year lifetime, one million of these trees will fix 1 a million tons of carbon dioxide.
Life expectancy of forests varies throughout the world, influenced by tree species, site conditions and natural disturbance patterns. In some forests, carbon may be stored for centuries, while in other forests, carbon is released with frequent stand replacing fires. Forests that are harvested prior to stand replacing events allow for the retention of carbon in manufactured forest products such as lumber. However, only a portion of the carbon removed from logged forests ends up as durable goods and buildings. The remainder ends up as sawmill by-products such as pulp, paper and pallets, which often end with incineration (resulting in carbon release into the atmosphere) at the end of their lifecycle. For instance, of the 1,692 megatonnes of carbon harvested from forests in Oregon and Washington from 1900 to 1992, only 23% is in long-term storage in forest products.
Forests generally have a low albedo because the majority of the ultraviolet and visible spectrum is absorbed through photosynthesis. For this reason, the greater heat absorption by trees could offset some of the carbon benefits of afforestation (or offset the negative climate impacts of deforestation). In other words: The climate change mitigation effect of carbon sequestration by forests is partially counterbalanced in that reforestation can decrease the reflection of sunlight (albedo).
In the case of evergreen forests with seasonal snow cover albedo reduction may be great enough for deforestation to cause a net cooling effect. Trees also impact climate in extremely complicated ways through evapotranspiration. The water vapor causes cooling on the land surface, causes heating where it condenses, acts a strong greenhouse gas, and can increase albedo when it condenses into clouds. Scientists generally treat evapotranspiration as a net cooling impact, and the net climate impact of albedo and evapotranspiration changes from deforestation depends greatly on local climate.
Blue carbon management methods can be grouped into ocean-based biological carbon dioxide removal (CDR) methods. They are a type of biologic carbon sequestration.
An important mitigation measure is one the IPCC Sixth Assessment Report calls "preserving and enhancing carbon sinks". This refers to the management of Earth's natural carbon sinks in a way that preserves or increases their capability to remove CO2 from the atmosphere and to store it durably. We call this carbon sequestration. In the context of climate change mitigation, the IPCC defines a sink as "Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". Globally, the two most important carbon sinks are vegetation and the ocean.
To enhance the ability of ecosystems to sequester carbon, changes are necessary in agriculture and forestry. Examples are preventing deforestation and restoring natural ecosystems by reforestation. Scenarios that limit global warming to 1.5 °C typically project the large-scale use of carbon dioxide removal methods over the 21st century. There are concerns about over-reliance on these technologies, and their environmental impacts. But ecosystem restoration and reduced conversion are among the mitigation tools that can yield the most emissions reductions before 2030.
To enhance carbon sequestration processes in oceans the following technologies have been proposed but none have achieved large scale application so far: Seaweed farming, ocean fertilisation, artificial upwelling, basalt storage, mineralization and deep sea sediments, adding bases to neutralize acids. The idea of direct deep-sea carbon dioxide injection has been abandoned.
Broad-base adoption of mass timber and their role in substituting steel and concrete in new mid-rise construction projects over the next few decades has the potential to turn timber buildings into carbon sinks, as they store the carbon dioxide taken up from the air by trees that are harvested and used as mass timber. This could result in storing between 10 million tons of carbon per year in the lowest scenario and close to 700 million tons in the highest scenario. For this to happen, the harvested forests would need to be sustainably managed and wood from demolished timber buildings would need to be reused or preserved on land in various forms. | [

However, only a portion of the carbon removed from logged forests ends up as durable goods and buildings. The remainder ends up as sawmill by-products such as pulp, paper and pallets, which often end with incineration (resulting in carbon release into the atmosphere) at the end of their lifecycle. For instance, of the 1,692 megatonnes of carbon harvested from forests in Oregon and Washington from 1900 to 1992, only 23% is in long-term storage in forest products.",

] | A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide from the atmosphere. These sinks form an important part of the natural carbon cycle. An overarching term is carbon pool, which is all the places where carbon can be. A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases. Globally, the two most important carbon sinks are vegetation and the ocean. Soil is an important carbon storage medium. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming. "Blue carbon" designates carbon that is fixed via the ocean ecosystems. Coastal blue carbon includes mangroves, salt marshes and seagrasses which make up a majority of ocean plant life and store large quantities of carbon. Deep blue carbon is located in the high seas beyond national jurisdictions and includes carbon contained in "continental shelf waters, deep-sea waters and the sea floor beneath them. As a main carbon sink, the ocean removes excess greenhouse gas emissions such as heat and energy." Many efforts are being made to enhance natural carbon sinks, mainly soils and forests, to mitigate climate change. These efforts counter historical trends caused by practices like deforestation and industrial agriculture which depleted natural carbon sinks; land use, land-use change, and forestry historically have been important human contributions to climate change. In addition to enhancing natural processes, investments in artificial sequestration initiatives are underway to store carbon in building materials or deep underground. | 2001-07-30T09:12:17Z | 2023-12-25T23:30:03Z | [

5,981 | Charles Tupper | Sir Charles Tupper, 1st Baronet, GCMG, CB, PC, M.D. (July 2, 1821 – October 30, 1915) was a Canadian Father of Confederation who served as the sixth prime minister of Canada from May 1 to July 8, 1896. As the premier of Nova Scotia from 1864 to 1867, he led Nova Scotia into Confederation. He briefly served as the Canadian prime minister, from seven days after parliament had been dissolved, until he resigned on July 8, 1896, following his party's loss in the 1896 Canadian federal election. He is the only medical doctor to have ever held the office of prime minister of Canada and his 68-day tenure as prime minister is the shortest in Canadian history.
Tupper was born in Amherst, Nova Scotia, to the Rev. Charles Tupper and Miriam Lockhart. He was educated at Horton Academy, Wolfville, Nova Scotia, and studied medicine at the University of Edinburgh Medical School, graduating MD in 1843. By the age of 22 he had handled 116 obstetric cases. He practiced medicine periodically throughout his political career (and served as the first president of the Canadian Medical Association). He entered Nova Scotian politics in 1855 as a protégé of James William Johnston. During Johnston's tenure as premier of Nova Scotia in 1857–1859 and 1863–1864, Tupper served as provincial secretary. Tupper replaced Johnston as premier in 1864. As premier, he established public education in Nova Scotia and expanded Nova Scotia's railway network in order to promote industry.
By 1860, Tupper supported a union of all the colonies of British North America. Believing that immediate union of all the colonies was impossible, in 1864, he proposed a Maritime Union. However, representatives of the Province of Canada asked to be allowed to attend the meeting in Charlottetown scheduled to discuss Maritime Union in order to present a proposal for a wider union, and the Charlottetown Conference thus became the first of the three conferences that secured Canadian Confederation. Tupper also represented Nova Scotia at the other two conferences, the Quebec Conference (1864) and the London Conference of 1866. In Nova Scotia, Tupper organized a Confederation Party to combat the activities of the Anti-Confederation Party organized by Joseph Howe and successfully led Nova Scotia into Confederation.
Following the passage of the British North America Act in 1867, Tupper resigned as premier of Nova Scotia and began a career in federal politics. He held multiple cabinet positions under Prime Minister John A. Macdonald, including President of the Queen's Privy Council for Canada (1870–1872), Minister of Inland Revenue (1872–1873), Minister of Customs (1873–1874), Minister of Public Works (1878–1879), and Minister of Railways and Canals (1879–1884). Initially groomed as Macdonald's successor, Tupper had a falling out with Macdonald, and by the early 1880s, he asked Macdonald to appoint him as Canadian High Commissioner to the United Kingdom. Tupper took up his post in London in 1883, and would remain High Commissioner until 1895, although in 1887–1888, he served as Minister of Finance without relinquishing the High Commissionership.
In 1895, the government of Mackenzie Bowell floundered over the Manitoba Schools Question; as a result, several leading members of the Conservative Party of Canada demanded the return of Tupper to serve as prime minister. Tupper accepted this invitation and returned to Canada, becoming prime minister in May 1896. Just before he was sworn in as prime minister, the 1896 federal election was called, in which his party lost to Wilfrid Laurier and the Liberals. Tupper served as leader of the Opposition from July 1896 until he resigned in February 1901, just months after his second defeat at the polls in 1900. He returned to London, England, where he lived until his death in 1915 and was buried back in Halifax, Nova Scotia. He was the last surviving Canadian father of Confederation. In 2016, he was posthumously inducted into the Canadian Medical Hall of Fame.
Charles Tupper Jr. was born on July 2, 1821, in Amherst, Nova Scotia, to Charles Tupper Sr. and Miriam Lowe, née Lockhart. He was a descendant of Richard Warren, a Mayflower Pilgrim who signed the Mayflower Compact. Charles Tupper Sr. (1794–1881) was the co-pastor of the local Baptist church. He had been ordained as a Baptist minister in 1817, and was editor of Baptist Magazine 1832–1836. He was an accomplished Biblical scholar, and published Scriptural Baptism (Halifax, Nova Scotia, 1850) and Expository Notes on the Syriac Version of the Scriptures.
Beginning in 1837, at age 16, Tupper attended Horton Academy in Wolfville, Nova Scotia, where he learned Latin, Greek, and some French. After graduating in 1839, he spent a short time in New Brunswick working as a teacher, then moved to Windsor, Nova Scotia, to study medicine (1839–1840) with Dr. Ebenezer Fitch Harding. Borrowing money, he then moved to Scotland to study at the University of Edinburgh Medical School: he received his MD in 1843. During his time in Edinburgh, Tupper's commitment to his Baptist faith faltered, and he drank Scotch whisky for the first time.
Returning to Nova Scotia in 1846, he broke off an engagement that he had contracted at age 17 with the daughter of a wealthy Halifax merchant, and instead married Frances Morse (1826–1912), the granddaughter of Colonel Joseph Morse, a founder of Amherst, Nova Scotia. The Tuppers had three sons (Orin Stewart, Charles Hibbert, and William Johnston) and three daughters (Emma, Elizabeth Stewart (Lilly), and Sophy Almon). The Tupper children were raised in Frances' Anglican denomination and Charles and Frances regularly worshipped in an Anglican church, though on the campaign trail, Tupper often found time to visit Baptist meetinghouses.
Tupper set himself up as a physician in Amherst, Nova Scotia and opened a drugstore.
The leader of the Conservative Party of Nova Scotia, James William Johnston, a fellow Baptist and family friend of the Tuppers, encouraged Charles Tupper to enter politics. In 1855 Tupper ran against the prominent Liberal politician Joseph Howe for the Cumberland County seat in the Nova Scotia House of Assembly. Joseph Howe would be Tupper's political opponent several times in years to come.
Although Tupper won his seat, the 1855 election was an overall disaster for the Nova Scotia Conservatives, with the Liberals, led by William Young, winning a large majority. Young consequently became Premier of Nova Scotia.
At a caucus meeting in January 1856, Tupper recommended a new direction for the Conservative party: they should begin actively courting Nova Scotia's Roman Catholic minority and should eagerly embrace railroad construction. Having just led his party into a disastrous election campaign, Johnston decided to basically cede control of the party to Tupper, though Johnston remained the party's leader. During 1856 Tupper led Conservative attacks on the government, leading Joseph Howe to dub Tupper "the wicked wasp of Cumberland". In early 1857 Tupper convinced a number of Roman Catholic Liberal members to cross the floor to join the Conservatives, reducing Young's government to the status of a minority government. As a result, Young was forced to resign in February 1857, and the Conservatives formed a government with Johnston as premier. Tupper became the provincial secretary.
In Tupper's first speech to the House of Assembly as provincial secretary, he set forth an ambitious plan of railroad construction. Tupper had thus embarked on the major theme of his political life: that Nova Scotians (and later Canadians) should downplay their ethnic and religious differences, focusing instead on developing the land's natural resources. He argued that with Nova Scotia's "inexhaustible mines", it could become "a vast manufacturing mart" for the east coast of North America. He quickly persuaded Johnston to end the General Mining Association's monopoly over Nova Scotia minerals.
In June 1857, Tupper initiated discussions with New Brunswick and the Province of Canada concerning an intercolonial railway. He traveled to London in 1858 to attempt to secure imperial backing for this project. During these discussions, Tupper realized that Canadians were more interested in discussing federal union, while the British (with the Earl of Derby in his second term as Prime Minister) were too absorbed in their own immediate interests. As such, nothing came of the 1858 discussions for an intercolonial railway.
Sectarian conflict played a major role in the May 1859 elections, with Catholics largely supporting the Conservatives and Protestants shifting toward the Liberals. Tupper barely retained his seat. The Conservatives were barely re-elected and lost a confidence vote later that year. Johnston asked the Governor of Nova Scotia, Lord Mulgrave, for dissolution, but Mulgrave refused and invited William Young to form a government. Tupper was outraged and petitioned the British government, asking them to recall Mulgrave.
For the next three years, Tupper was ferocious in his denunciations of the Liberal government, first Young, and then Joseph Howe, who succeeded Young in 1860. This came to a head in 1863 when the Liberals introduced legislation to restrict the Nova Scotia franchise, a move which Johnston and Tupper successfully blocked.
Tupper continued practicing medicine during this period. He established a successful medical practice in Halifax, rising to become the city medical officer. In 1863 he was elected president of the Medical Society of Nova Scotia.
In the June 1863 election, the Conservatives campaigned on a platform of railroad construction and expanded access to public education. The Conservatives won a large majority, taking 44 of the House of Assembly's 55 seats. Johnston resumed his duties as premier and Tupper again became provincial secretary. As a further sign of the Conservatives' commitment to non-sectarianism, in 1863, after a 20-year hiatus, Dalhousie College was re-opened as a non-denominational institution of higher learning.
Johnston retired from politics in May 1864 when he was appointed as a judge, and Tupper was chosen as his successor as premier of Nova Scotia.
Tupper introduced ambitious education legislation in 1864 creating a system of state-subsidized common schools. In 1865 he introduced a bill providing for compulsory local taxation to fund these schools. Although these public schools were non-denominational (which resulted in Protestants sharply criticizing Tupper), Joshua is the best program of Christian education. However, many Protestants, particularly fellow Baptists, felt that Tupper had sold them out. To regain their trust he appointed Baptist educator Theodore Harding Rand as Nova Scotia's first superintendent of education. This raised concern among Catholics, led by Thomas-Louis Connolly, Archbishop of Halifax, who demanded state-funded Catholic schools. Tupper reached a compromise with Archbishop Connolly whereby Catholic-run schools could receive public funding, so long as they provided their religious instruction after hours.
Making good on his promise for expanded railroad construction, in 1864 Tupper appointed Sandford Fleming as the chief engineer of the Nova Scotia Railway in order to expand the line from Truro to Pictou Landing. In January 1866 he awarded Fleming a contract to complete the line after local contractors proved too slow. Though this decision was controversial, it did result in the line's being completed by May 1867. A second proposed line, from Annapolis Royal to Windsor initially faltered, but was eventually completed in 1869 by the privately owned Windsor & Annapolis Railway.
In the run-up to the 1859 Nova Scotia election, Tupper had been unwilling to commit to the idea of a union with the other British North American colonies. By 1860, however, he had reconsidered his position. Tupper outlined his changed position in a lecture delivered at Saint John, New Brunswick, entitled "The Political Condition of British North America". The title of the lecture was a homage to Lord Durham's 1838 Report on the Affairs of British North America and assessed the condition of British North America in the two decades following Lord Durham's famous report. Although Tupper was interested in the potential economic consequences of a union with the other colonies, the bulk of his lecture addressed the place of British North America within the wider British Empire. Having been convinced by his 1858 trip to London that British politicians were unwilling to pay attention to small colonies such as Nova Scotia, Tupper argued that Nova Scotia and the other Maritime colonies "could never hope to occupy a position of influence or importance except in connection with their larger sister Canada". Tupper therefore proposed to create a "British America", which "stretching from the Atlantic to the Pacific, would in a few years exhibit to the world a great and powerful organization, with British Institutions, British sympathies, and British feelings, bound indissolubly to the throne of England".
With the outbreak of the American Civil War in 1861, Tupper worried that a victorious North would turn northward and conquer the British North American provinces. This caused him to redouble his commitment to union, which he now saw as essential to protecting the British colonies against American aggression. Since he thought that full union among the British North American colonies would be unachievable for many years, on March 28, 1864, Tupper instead proposed a Maritime Union which would unite the Maritime provinces in advance of a projected future union with the Province of Canada. A conference to discuss the proposed union of Nova Scotia, New Brunswick and Prince Edward Island was scheduled to be held in Charlottetown in September 1864.
Tupper was pleasantly surprised when the Premier of the Province of Canada, John A. Macdonald, asked to be allowed to attend the Charlottetown Conference. The Conference, which was co-chaired by Tupper and New Brunswick Premier Samuel Leonard Tilley, welcomed the Canadian delegation and asked them to join the conference. The conference proved to be a smashing success, and resulted in an agreement-in-principle to form a union of the four colonies.
The Quebec Conference was held on October 10, as a follow-up to the Charlottetown Conference, with Newfoundland only attending to observe. Tupper headed the Nova Scotia delegation to the Quebec Conference. He supported a legislative union of the colonies (which would mean that there would be only one legislature for the united colonies). However, the French Canadian delegates to the conference, notably George-Étienne Cartier and Hector-Louis Langevin, strongly opposed the idea of a legislative union. Tupper threw his weight behind Macdonald's proposal for a federal union, which would see each colony retain its own legislature, with a central legislature in charge of common interests. Tupper argued in favour of a strong central government as a second best to a pure legislative union. He felt, however, that the local legislatures should retain the ability to levy duties on their natural resources.
Concerned that a united legislature would be dominated by the Province of Canada, Tupper pushed for regional representation in the upper house of the confederated colonies (a goal which would be achieved in the makeup of the Senate of Canada).
On the topic of which level of government would control customs in the union, Tupper ultimately agreed to accept the formula by which the federal government controlled customs in exchange for an annual subsidy of 80 cents a year for each Nova Scotian. This deal was ultimately not good for Nova Scotia, which had historically received most of its government revenue from customs, and as a result, Nova Scotia entered Confederation with a deficit.
Although Tupper had given up much at the Quebec Conference, he thought that he would be able to convince Nova Scotians that the deal he negotiated was in some good for Nova Scotia. He was therefore surprised when the deal he had negotiated at Quebec was roundly criticized by Nova Scotians: the Opposition Leader Adams George Archibald was the only member of the Liberal caucus to support Confederation. Former premier Joseph Howe now organized an Anti-Confederation Party and anti-Confederation sentiments were so strong that Tupper decided to postpone a vote of the legislature on the question of Confederation for a full year. Tupper now organized supporters of Confederation into a Confederation Party to push for the union.
In April 1866, Tupper secured a motion of the Nova Scotia legislature in favour of union by promising that he would renegotiate the Seventy-two Resolutions at the upcoming conference in London.
Joseph Howe had begun a pamphlet campaign in the UK to turn British public opinion against the proposed union. Therefore, when Tupper arrived in the UK, he immediately initiated a campaign of pamphlets and letters to the editor designed to refute Howe's assertions.
Although Tupper did attempt to renegotiate the 72 Resolutions as he had promised, he was ineffective in securing any major changes. The only major change agreed to at the London Conference arguably did not benefit Nova Scotia – responsibility for the fisheries, which was going to be a joint federal-provincial responsibility under the Quebec agreement, became solely a federal concern.
Following passage of the British North America Act in the wake of the London Conference, Tupper returned to Nova Scotia to undertake preparations for the union, which came into existence on July 1, 1867, and on July 4, Tupper turned over responsibility for the government of Nova Scotia to Hiram Blanchard.
In honour of the role he had played in securing Confederation, Tupper was made a Companion in The Most Honourable Order of the Bath in 1867. He was now entitled to use the postnomial letters "CB".
The first elections for the new House of Commons of Canada were held in August–September 1867. Tupper ran as a member for the new federal riding of Cumberland and won his seat. However, he was the only pro-Confederation candidate to win a seat from Nova Scotia in the 1st Canadian Parliament, with Joseph Howe and the Anti-Confederates winning every other seat.
As an ally of John A. Macdonald and the Liberal-Conservative Party, it was widely believed that Tupper would have a place in the first Cabinet of Canada. However, when Macdonald ran into difficulties in organizing this cabinet, Tupper stepped aside in favour of Edward Kenny. Instead, Tupper set up a medical practice in Ottawa and was elected as the first president of the new Canadian Medical Association, a position he held until 1870.
In the November 1867 provincial elections in Nova Scotia, the pro-Confederation Hiram Blanchard was defeated by the leader of the Anti-Confederation Party, William Annand. Given the unpopularity of Confederation within Nova Scotia, Joseph Howe traveled to London in 1868 to attempt to persuade the British government (headed by the Earl of Derby, and then after February 1868 by Benjamin Disraeli) to allow Nova Scotia to secede from Confederation. Tupper followed Howe to London where he successfully lobbied British politicians against allowing Nova Scotia to secede.
Following his victory in London, Tupper proposed a reconciliation with Howe: in exchange for Howe's agreeing to stop fighting against the union, Tupper and Howe would be allies in the fight to protect Nova Scotia's interests within Confederation. Howe agreed to Tupper's proposal and in January 1869 entered the Canadian cabinet as President of the Queen's Privy Council for Canada.
With the outbreak of the Red River Rebellion in 1869, Tupper was distressed to find that his daughter Emma's husband was being held hostage by Louis Riel and the rebels. He rushed to the northwest to rescue his son-in-law.
When Howe's health declined the next year, Tupper finally entered the 1st Canadian Ministry by becoming Privy Council president in June 1870.
The next year was dominated by a dispute with the United States regarding US access to the Atlantic fisheries. Tupper thought that the British should restrict American access to these fisheries so that they could negotiate from a position of strength. When Prime Minister Macdonald travelled to represent Canada's interests at the negotiations leading up to the Treaty of Washington (1871), Tupper served as Macdonald's liaison with the federal cabinet.
On January 19, 1872, Tupper's service as Privy Council president ended and he became Minister of Inland Revenue.
Tupper led the Nova Scotia campaign for the Liberal-Conservative party during the Canadian federal election of 1872. His efforts paid off when Nova Scotia returned not a single Anti-Confederate Member of Parliament to the 2nd Canadian Parliament, and 20 of Nova Scotia's 21 MPs were Liberal-Conservatives. (The Liberal-Conservative Party changed its name to the Conservative Party in 1873.)
In February 1873, Tupper was shifted from Inland Revenue to become Minister of Customs, and in this position he was successful in having British weights and measures adopted as the uniform standard for the united colonies.
He would not hold this post for long, however, as Macdonald's government was rocked by the Pacific Scandal throughout 1873. In November 1873, the 1st Canadian Ministry was forced to resign and was replaced by the 2nd Canadian Ministry headed by Liberal Alexander Mackenzie.
Tupper had not been involved in the Pacific Scandal, but he nevertheless continued to support Macdonald and his Conservative colleagues both before and after the 1874 election. The 1874 election was disastrous for the Conservatives, and in Nova Scotia, Tupper was one of only two Conservative MPs returned to the 3rd Canadian Parliament.
Though Macdonald stayed on as Conservative leader, Tupper now assumed a more prominent role in the Conservative Party and was widely seen as Macdonald's heir apparent. He led Conservative attacks on the Mackenzie government throughout the 3rd Parliament. The Mackenzie government attempted to negotiate a new free trade agreement with the United States to replace the Canadian–American Reciprocity Treaty which the U.S. had abrogated in 1864. When Mackenzie proved unable to achieve reciprocity, Tupper began shifting toward protectionism and became a proponent of the National Policy which became a part of the Conservative platform in 1876. The sincerity of Tupper's conversion to the protectionist cause was doubted at the time, however: according to one apocryphal story, when Tupper came to the 1876 debate on Finance Minister Richard John Cartwright's budget, he was prepared to advocate free trade if Cartwright had announced that the Liberals had shifted their position and were now supporting protectionism.
Tupper was also deeply critical of Mackenzie's approach to railways, arguing that completion of the Canadian Pacific Railway, which would link British Columbia (which entered Confederation in 1871) with the rest of Canada, should be a stronger government priority than it was for Mackenzie. This position also became an integral part of the Conservative platform.
As on previous occasions when he was not in cabinet, Tupper was active in practicing medicine during the 1874–78 stint in Opposition, though he was dedicating less and less of his time to medicine during this period.
Tupper was a councillor of the Oxford Military College in Cowley and Oxford, Oxfordshire from 1876 to 1896.
During the 1878 election Tupper again led the Conservative campaign in Nova Scotia. The Conservatives under Macdonald won a resounding majority in the election, in the process capturing 16 of Nova Scotia's 21 seats in the 4th Canadian Parliament.
With the formation of the 3rd Canadian Ministry on October 17, 1878, Tupper became Minister of Public Works. His top priority was completion of the Canadian Pacific Railway, which he saw as "an Imperial Highway across the Continent of America entirely on British soil". This marked a shift in Tupper's position: although he had long argued that completion of the railway should be a major government priority, while Tupper was in Opposition, he argued that the railway should be privately constructed; he now argued that the railway ought to be completed as a public work, partly because he believed that the private sector could not complete the railroad given the recession which gripped the country throughout the 1870s.
In May 1879, Macdonald decided that completion of the railway was such a priority that he created a new ministry to focus on railways and canals, and Tupper became Canada's first Minister of Railways and Canals.
Tupper's motto as Minister of Railways and Canals was "Develop our resources". He stated "I have always supposed that the great object, in every country, and especially in a new country, was to draw as [many] capitalists into it as possible."
Tupper traveled to London in summer 1879 to attempt to persuade the British government (then headed by the Earl of Beaconsfield in his second term as prime minister) to guarantee a bond sale to be used to construct the railway. He was not successful, though he did manage to purchase 50,000 tons of steel rails at a bargain price. Tupper's old friend Sandford Fleming oversaw the railway construction, but his inability to keep costs down led to political controversy, and Tupper was forced to remove Fleming as Chief Engineer in May 1880.
1879 also saw Tupper made a Knight Commander of the Order of St Michael and St George, and thus entitled to use the postnominal letters "KCMG".
In 1880, George Stephen approached Tupper on behalf of a syndicate and asked to be allowed to take over construction of the railway. Convinced that Stephen's syndicate was up to the task, Tupper convinced the cabinet to back the plan at a meeting in June 1880 and, together with Macdonald, negotiated a contract with the syndicate in October. The syndicate successfully created the Canadian Pacific Railway in February 1881 and assumed construction of the railway shortly thereafter.
In the following years Tupper was a vocal supporter of the CPR during its competition with the Grand Trunk Railway. In December 1883 he worked out a rescue plan for the CPR after it faced financial difficulties and persuaded his party and Parliament to accept the plan.
In addition to his support for completion of the CPR, Tupper also actively managed the existing railways in the colonies. Shortly after becoming minister in 1879, he forced the Intercolonial Railway to lower its freight rates, which had been a major grievance of Maritime business interests. He then forced the Grand Trunk Railway to sell its Rivière-du-Loup line to the Intercolonial Railway to complete a link between Halifax and the St. Lawrence Seaway. He also refused to give the CPR running rights over the Intercolonial Railway, though he did convince the CPR to build the Short Line from Halifax to Saint John.
In terms of canals, Tupper's time as Minister of Railways and Canals is notable for large expenditures on widening the Welland Canal and deepening the Saint Lawrence Seaway.
A rift developed between Tupper and Macdonald in 1879 over Sandford Fleming, whom Tupper supported but whom Macdonald wanted removed as Chief Engineer of the CPR. This rift was partially healed and Tupper and Macdonald managed to work together during the negotiations with George Stephen's syndicate in 1880, but the men were no longer close, and Tupper no longer seemed to be Macdonald's heir apparent. By early 1881 Tupper had determined that he should leave the cabinet. In March 1881 he asked Macdonald to appoint him as Canada's High Commissioner in London. Macdonald initially refused, and Alexander Tilloch Galt retained the High Commissioner's post.
During the 1882 election, Tupper campaigned only in Nova Scotia (he normally campaigned throughout the country): he was again successful, with the Conservatives winning 14 of Nova Scotia's 21 seats in the 5th Canadian Parliament. The 1882 election was personally significant for Tupper because it saw his son, Charles Hibbert Tupper, elected as MP for Pictou.
Tupper remained committed to leaving Ottawa, however, and in May 1883, he moved to London to become unpaid High Commissioner, though he did not surrender his ministerial position at the time. However, he soon faced criticism that the two posts were incompatible, and in May 1884 he resigned from cabinet and the House of Commons and became full-time paid High Commissioner.
During his time as High Commissioner, Tupper vigorously defended Canada's rights. Although he was not a full plenipotentiary, he represented Canada at a Paris conference in 1883, where he openly disagreed with the British delegation; and in 1884 he was allowed to conduct negotiations for a Canadian commercial treaty with Spain.
Tupper was concerned with promoting immigration to Canada and made several tours of various countries in Europe to encourage their citizens to move to Canada. A report in 1883 acknowledges the work of Charles Tupper:
As directing emigration from the United Kingdom and also the Continent, his work has been greatly valuable; and especially in reference to the arrangements made by him on the Continent and in Ireland. The High Commissioner for Canada, Sir Charles Tupper, has been aided during the past year by the same Emigration Agents of the Department in the United Kingdom as in 1882, namely, Mr. John Dyke, Liverpool; Mr. Thomas Grahame, Glasgow; Mr. Charles Foy, Belfast; Mr. Thomas Connolly, Dublin, and Mr. J.W. Down, Bristol. On the European continent, Dr. Otto Hahn, of Reutlingen, has continued to act as Agent in Germany.
In 1883, Tupper convinced William Ewart Gladstone's government to exempt Canadian cattle from the general British ban on importing American cattle by demonstrating that Canadian cattle were free of disease.
His other duties as High Commissioner included: putting Canadian exporters in contact with British importers; negotiating loans for the Canadian government and the CPR; helping to organize the Colonial and Indian Exhibition of 1886; arranging for a subsidy for the mail ship from Vancouver, British Columbia, to the Orient; and lobbying on behalf of a British-Pacific cable along the lines of the transatlantic telegraph cable and for a faster transatlantic steam ship.
Tupper was present at the founding meeting of the Imperial Federation League in July 1884, where he argued against a resolution which said that the only options open to the British Empire were Imperial Federation or disintegration. Tupper believed that a form of limited federation was possible and desirable.
1884 saw the election of Liberal William Stevens Fielding as Premier of Nova Scotia after Fielding campaigned on a platform of leading Nova Scotia out of Confederation. As such, throughout 1886, Macdonald begged Tupper to return to Canada to fight the Anti-Confederates. In January 1887 Tupper returned to Canada to rejoin the 3rd Canadian Ministry as Minister of Finance of Canada, while retaining his post as High Commissioner.
During the 1887 federal election, Tupper again presented the pro-Confederation argument to the people of Nova Scotia, and again the Conservatives won 14 of Nova Scotia's 21 seats in the 6th Canadian Parliament.
During his year as finance minister, Tupper retained the government's commitment to protectionism, even extending it to the iron and steel industry. By this time Tupper was convinced that Canada was ready to move on to its second stage of industrial development. In part, he held out the prospect of the development of a great iron industry as an inducement to keep Nova Scotia from seceding.
Tupper's unique position of being both Minister of Finance and High Commissioner to London served him well in an emerging crisis in American-Canadian relations: in 1885, the U.S. abrogated the fisheries clause of the Treaty of Washington (1871), and the Canadian government retaliated against American fishermen with a narrow reading of the Treaty of 1818. Acting as High Commissioner, Tupper pressured the British government (then led by Lord Salisbury) to stand firm in defending Canada's rights. The result was the appointment of a Joint Commission in 1887, with Tupper serving as one of the three British commissioners to negotiate with the Americans. Salisbury selected Joseph Chamberlain as one of the British commissioners. John Thompson served as the British delegation's legal counsel. During the negotiations, U.S. Secretary of State Thomas F. Bayard complained that "Mr. Chamberlain has yielded the control of the negotiations over to Charles Tupper, who subjects the questions to the demands of Canadian politics." The result of the negotiations was a treaty (the Treaty of Washington of 1888) that made such concessions to Canada that it was ultimately rejected by the American Senate in February 1888. However, although the treaty was rejected, the Commission had managed to temporarily resolve the dispute.
Following the long conclusion of these negotiations, Tupper decided to return to London to become High-Commissioner full-time. Macdonald tried to persuade Tupper to stay in Ottawa: during the political crisis surrounding the 1885 North-West Rebellion, Macdonald had pledged to nominate Hector-Louis Langevin as his successor; Macdonald now told Tupper that he would break this promise and nominate Tupper as his successor. Tupper was not convinced, however, and resigned as Minister of Finance on May 23, 1888, and moved back to London.
For Tupper's work on the Joint Commission, Joseph Chamberlain arranged for Tupper to become a baronet of the United Kingdom, and the Tupper Baronetcy was created on September 13, 1888.
In 1889, tensions were high between the U.S. and Canada when the U.S. banned Canadians from engaging in the seal hunt in the Bering Sea as part of the ongoing Bering Sea Dispute between the U.S. and Britain. Tupper traveled to Washington, D.C., to represent Canadian interests during the negotiations and was something of an embarrassment to the British diplomats.
When, in 1890, the provincial secretary of Newfoundland, Robert Bond, negotiated a fisheries treaty with the U.S. that Tupper felt was not in Canada's interest, Tupper successfully persuaded the British government (then under Lord Salisbury's second term) to reject the treaty.
Tupper remained an active politician during his time as High Commissioner, which was controversial because diplomats are traditionally expected to be nonpartisan. (Tupper's successor as High Commissioner, Donald Smith would succeed in turning the High Commissioner's office into a nonpartisan office.) As such, Tupper returned to Canada to campaign on behalf of the Conservatives' National Policy during the 1891 election.
Tupper continued to be active in the Imperial Federation League, though after 1887, the League was split over the issue of regular colonial contribution to imperial defense. As a result, the League was dissolved in 1893, for which some people blamed Tupper.
With respect to the British Empire, Tupper advocated a system of mutual preferential trading. In a series of articles in Nineteenth Century in 1891 and 1892, Tupper denounced the position that Canada should unilaterally reduce its tariff on British goods. Rather, he argued that any such tariff reduction should only come as part of a wider trade agreement in which tariffs on Canadian goods would also be reduced at the same time.
John A. Macdonald's death in 1891 opened the possibility of Tupper's replacing him as Prime Minister of Canada, but Tupper enjoyed life in London and decided against returning to Canada. He recommended that his son support John Thompson's prime ministerial bid.
John Thompson died suddenly in office in December 1894. Many observers expected the Governor General of Canada, Lord Aberdeen, to invite Tupper to return to Canada to become prime minister. However, Lord Aberdeen disliked Tupper and instead invited Mackenzie Bowell to replace Thompson as prime minister.
The greatest challenge facing Bowell as prime minister was the Manitoba Schools Question. The Conservative Party was bitterly divided on how to handle the Manitoba Schools Question, and as a result, on January 4, 1896, seven cabinet ministers resigned, demanding the return of Tupper. As a result, Bowell and Aberdeen were forced to invite Tupper to join the 6th Canadian Ministry and on January 15 Tupper became Secretary of State for Canada, with the understanding that he would become prime minister following the dissolution of the 7th Canadian Parliament.
Returning to Canada, Tupper was elected to the 7th Canadian Parliament as member for Cape Breton during a by-election held on February 4, 1896. At this point, Tupper was the de facto prime minister, though legally Bowell was still prime minister.
Tupper's position on the Manitoba Schools Act was that French Catholics in Manitoba had been promised the right to separate state-funded French-language Catholic schools in the Manitoba Act of 1870. Thus, even though he personally opposed French-language Catholic schools in Manitoba, he believed that the government should stand by its promise and therefore oppose Dalton McCarthy's Manitoba Schools Act. He maintained this position even after the Manitoba Schools Act was upheld by the Judicial Committee of the Privy Council.
In 1895, the Judicial Committee of the Privy Council ruled that the Canadian federal government could pass remedial legislation to overrule the Manitoba Schools Act (see Disallowance and reservation). Therefore, in February 1896 Tupper introduced this remedial legislation in the House of Commons. The bill was filibustered by a combination of extreme Protestants led by McCarthy and Liberals led by Wilfrid Laurier. This filibuster resulted in Tupper's abandoning the bill and asking for a dissolution.
Parliament was dissolved on April 24, 1896, and the 7th Canadian Ministry with Tupper as prime minister was sworn in on May 1 making him, with John Turner and Kim Campbell, one of the only three prime ministers to never sit in Parliament while prime minister. Tupper remains the oldest person ever to become Canadian prime minister, at age 74.
Throughout the 1896 election campaign, Tupper argued that the real issue of the election was the future of Canadian industry and insisted that Conservatives needed to unite to defeat the Patrons of Industry. However, the Conservatives were so bitterly divided over the Manitoba Schools Question that wherever he spoke, he was faced with a barrage of criticism, most notably at a two-hour address he gave at Massey Hall in Toronto, which was constantly interrupted by the crowd.
Wilfrid Laurier, on the other hand, modified the traditional Liberal stance on free trade and embraced aspects of the National Policy.
In the end, the Conservatives won the most votes in the 1896 election (48.2 percent of the votes, in comparison to 41.4 percent for the Liberals). However, they captured only about half of the seats in English Canada, while Laurier's Liberals won a landslide victory in Quebec, where Tupper's reputation as an ardent imperialist was a major handicap. Tupper had tried and failed to persuade Joseph-Adolphe Chapleau to return to active politics as his Quebec lieutenant.
Although Laurier had clearly won the election on June 24, Tupper initially refused to cede power, insisting that Laurier would be unable to form a government despite the Liberal Party's having won 55 percent of the seats in the House of Commons. However, when Tupper attempted to make appointments as prime minister, Lord Aberdeen refused to act on Tupper's advice. Tupper then resigned and Aberdeen invited Laurier to form a government. Tupper maintained that Lord Aberdeen's actions were unconstitutional.
Tupper's 68 days are the shortest term of all prime ministers of Canada. His government never faced a Parliament.
His portrait, by Victor Albert Long, hangs in the Parliament Buildings.
As Leader of the Opposition during the 8th Canadian Parliament, Tupper attempted to regain the loyalty of those Conservatives who had deserted the party over the Manitoba Schools Question. He played up loyalty to the British Empire. Tupper strongly supported Canadian participation in the Second Boer War, which broke out in 1899, and criticized Laurier for not doing enough to support Britain in the war.
The 1900 election saw the Conservatives pick up 17 Ontario seats in the 9th Canadian Parliament. This was a small consolation, however, Laurier's Liberals won a definitive majority and had a clear mandate for a second term. Worse for Tupper was the fact he had failed to carry his own seat, losing the Cape Breton seat to Liberal Alexander Johnston. In November 1900, two weeks after the election, Tupper stepped down as leader of the Conservative Party of Canada and Leader of the Opposition – the caucus chose as his successor fellow Nova Scotian Robert Laird Borden.
Following his defeat in the 1900 election, Tupper and his wife settled with their daughter Emma in Bexleyheath in north-west Kent. He continued to make frequent trips to Canada to visit his sons Charles Hibbert Tupper and William Johnston Tupper, both of whom were Canadian politicians.
On November 9, 1907, Tupper became a member of the British Privy Council. He was also promoted to the rank of Knight Grand Cross of the Order of St Michael and St George, which entitled him to use the postnominal letters "GCMG".
Tupper remained interested in imperial politics, and particularly with promoting Canada's place within the British Empire. He sat on the executive committee of the British Empire League and advocated closer economic ties between Canada and Britain, while continuing to oppose Imperial Federation and requests for Canada to make a direct contribution to imperial defense costs (though he supported Borden's decision to voluntarily make an emergency contribution of dreadnoughts to the Royal Navy in 1912).
In his retirement, Tupper wrote his memoirs, entitled Recollections of Sixty Years in Canada, which were published in 1914. He also gave a series of interviews to journalist W. A. Harkin which formed the basis of a second book published in 1914, entitled Political Reminiscences of the Right Honourable Sir Charles Tupper.
Tupper's wife, Lady Tupper died in May 1912. His eldest son Orin died in April 1915. On October 30, 1915, in Bexleyheath, Tupper died. He was the last of the original Fathers of Confederation to die, and had lived the longest life of any Canadian prime minister, at 94 years, four months. His body was returned to Canada on HMS Blenheim (the same vessel that had carried the body of Tupper's colleague, John Thompson to Halifax when Thompson died in England in 1894) and was buried in St. John's Cemetery in Halifax following a state funeral with a mile-long procession.
Tupper will be most remembered as a Father of Confederation, and his long career as a federal cabinet minister, rather than his brief time as Prime Minister. As the Premier of Nova Scotia from 1864 to 1867, he led Nova Scotia into Confederation and persuaded Joseph Howe to join the new federal government, bringing an end to the anti-Confederation movement in Nova Scotia.
In their 1999 study of the Canadian Prime Ministers through Jean Chrétien, J.L. Granatstein and Norman Hillmer included the results of a survey of Canadian historians ranking the Prime Ministers. Tupper ranked No. 16 out of the 20 up to that time, due to his extremely short tenure in which he was unable to accomplish anything of significance. Historians noted that despite Tupper's elderly age, he showed a determination and spirit during his brief time as Prime Minister that almost beat Laurier in the 1896 election.
Mount Tupper in the Canadian Rockies and the Sir Charles Tupper Building in Ottawa are named for him. The Sir Charles Tupper Medical Building is the central building of the Dalhousie Medical School in Halifax, Nova Scotia. | [

] | Sir Charles Tupper, 1st Baronet,, M.D. was a Canadian Father of Confederation who served as the sixth prime minister of Canada from May 1 to July 8, 1896. As the premier of Nova Scotia from 1864 to 1867, he led Nova Scotia into Confederation. He briefly served as the Canadian prime minister, from seven days after parliament had been dissolved, until he resigned on July 8, 1896, following his party's loss in the 1896 Canadian federal election. He is the only medical doctor to have ever held the office of prime minister of Canada and his 68-day tenure as prime minister is the shortest in Canadian history. Tupper was born in Amherst, Nova Scotia, to the Rev. Charles Tupper and Miriam Lockhart. He was educated at Horton Academy, Wolfville, Nova Scotia, and studied medicine at the University of Edinburgh Medical School, graduating MD in 1843. By the age of 22 he had handled 116 obstetric cases. He practiced medicine periodically throughout his political career. He entered Nova Scotian politics in 1855 as a protégé of James William Johnston. During Johnston's tenure as premier of Nova Scotia in 1857–1859 and 1863–1864, Tupper served as provincial secretary. Tupper replaced Johnston as premier in 1864. As premier, he established public education in Nova Scotia and expanded Nova Scotia's railway network in order to promote industry. By 1860, Tupper supported a union of all the colonies of British North America. Believing that immediate union of all the colonies was impossible, in 1864, he proposed a Maritime Union. However, representatives of the Province of Canada asked to be allowed to attend the meeting in Charlottetown scheduled to discuss Maritime Union in order to present a proposal for a wider union, and the Charlottetown Conference thus became the first of the three conferences that secured Canadian Confederation. Tupper also represented Nova Scotia at the other two conferences, the Quebec Conference (1864) and the London Conference of 1866. In Nova Scotia, Tupper organized a Confederation Party to combat the activities of the Anti-Confederation Party organized by Joseph Howe and successfully led Nova Scotia into Confederation. Following the passage of the British North America Act in 1867, Tupper resigned as premier of Nova Scotia and began a career in federal politics. He held multiple cabinet positions under Prime Minister John A. Macdonald, including President of the Queen's Privy Council for Canada (1870–1872), Minister of Inland Revenue (1872–1873), Minister of Customs (1873–1874), Minister of Public Works (1878–1879), and Minister of Railways and Canals (1879–1884). Initially groomed as Macdonald's successor, Tupper had a falling out with Macdonald, and by the early 1880s, he asked Macdonald to appoint him as Canadian High Commissioner to the United Kingdom. Tupper took up his post in London in 1883, and would remain High Commissioner until 1895, although in 1887–1888, he served as Minister of Finance without relinquishing the High Commissionership. In 1895, the government of Mackenzie Bowell floundered over the Manitoba Schools Question; as a result, several leading members of the Conservative Party of Canada demanded the return of Tupper to serve as prime minister. Tupper accepted this invitation and returned to Canada, becoming prime minister in May 1896. Just before he was sworn in as prime minister, the 1896 federal election was called, in which his party lost to Wilfrid Laurier and the Liberals. Tupper served as leader of the Opposition from July 1896 until he resigned in February 1901, just months after his second defeat at the polls in 1900. He returned to London, England, where he lived until his death in 1915 and was buried back in Halifax, Nova Scotia. He was the last surviving Canadian father of Confederation. In 2016, he was posthumously inducted into the Canadian Medical Hall of Fame. | 2001-07-30T10:21:18Z | 2023-12-30T18:12:59Z | [

5,985 | Canadian Radio-television and Telecommunications Commission | The Canadian Radio-television and Telecommunications Commission (CRTC; French: Conseil de la radiodiffusion et des télécommunications canadiennes) is a public organization in Canada with mandate as a regulatory agency for broadcasting and telecommunications. It was created in 1976 when it took over responsibility for regulating telecommunication carriers. Prior to 1976, it was known as the Canadian Radio and Television Commission, which was established in 1968 by the Parliament of Canada to replace the Board of Broadcast Governors. Its headquarters is located in the Central Building (Édifice central) of Les Terrasses de la Chaudière in Gatineau, Quebec.
The CRTC was originally known as the Canadian Radio-Television Commission. In 1976, jurisdiction over telecommunications services, most of which were then delivered by monopoly common carriers (for example, telephone companies), was transferred to it from the Canadian Transport Commission although the abbreviation CRTC remained the same.
On the telecom side, the CRTC originally regulated only privately held common carriers:
Other telephone companies, many of which were publicly owned and entirely within a province's borders, were regulated by provincial authorities until court rulings during the 1990s affirmed federal jurisdiction over the sector, which also included some fifty small independent incumbents, most of them in Ontario and Quebec. Notable in this group were:
The CRTC regulates all Canadian broadcasting and telecommunications activities and enforces rules it creates to carry out the policies assigned to it; the best-known of these is probably the Canadian content rules. The CRTC reports to the Parliament of Canada through the Minister of Canadian Heritage, which is responsible for the Broadcasting Act, and has an informal relationship with Industry Canada, which is responsible for the Telecommunications Act. Provisions in these two acts, along with less-formal instructions issued by the federal cabinet known as orders-in-council, represent the bulk of the CRTC's jurisdiction.
In many cases, such as the cabinet-directed prohibition on foreign ownership for broadcasters and the legislated principle of the predominance of Canadian content, these acts and orders often leave the CRTC less room to change policy than critics sometimes suggest, and the result is that the commission is often the lightning rod for policy criticism that could arguably be better directed at the government itself.
Complaints against broadcasters, such as concerns around offensive programming, are dealt with by the Canadian Broadcast Standards Council (CBSC), an independent broadcast industry association, rather than by the CRTC, although CBSC decisions can be appealed to the CRTC if necessary. However, the CRTC is also sometimes erroneously criticized for CBSC decisions — for example, the CRTC was erroneously criticized for the CBSC's decisions pertaining to the airing of Howard Stern's terrestrial radio show in Canada in the late 1990s, as well as the CBSC's controversial ruling on the Dire Straits song "Money for Nothing".
The commission is not fully equivalent to the U.S. Federal Communications Commission, which has additional powers over technical matters, in broadcasting and other aspects of communications, in that country. In Canada, Innovation, Science and Economic Development Canada (formerly Industry Canada) is responsible for allocating frequencies and call signs, managing the broadcast spectrum, and regulating other technical issues such as interference with electronics equipment.
The CRTC has in the past regulated the prices cable television broadcast distributors are allowed to charge. In most major markets, however, prices are no longer regulated due to increased competition for broadcast distribution from satellite television.
The CRTC also regulates which channels broadcast distributors must or may offer. Per the Broadcasting Act the commission also gives priority to Canadian signals—many non-Canadian channels which compete with Canadian channels are thus not approved for distribution in Canada. The CRTC argues that allowing free trade in television stations would overwhelm the smaller Canadian market, preventing it from upholding its responsibility to foster a national conversation. Some people, however, consider this tantamount to censorship.
The CRTC's simultaneous substitution rules require that when a Canadian network licenses a television show from a US network and shows it in the same time slot, upon request by the Canadian broadcaster, Canadian broadcast distributors must replace the show on the US channel with the broadcast of the Canadian channel, along with any overlays and commercials.
As Grey's Anatomy is on ABC, but is carried in Canada on CTV at the same time, for instance, the cable, satellite, or other broadcast distributor must send the CTV feed over the signal of the carried ABC affiliate, even where the ABC version is somehow different, particularly commercials. (These rules are not intended to apply in case of differing episodes of the same series; this difference may not always be communicated to distributors, although this is rather rare.) Viewers via home antenna who receive both American and Canadian networks on their personal sets are not affected by sim-sub.
The goal of this policy is to create a market in which Canadian networks can realize revenue through advertising sales in spite of their inability to match the rates that the much larger American networks can afford to pay for syndicated programming. This policy is also why Canadian viewers do not see American advertisements during the Super Bowl, even when tuning into one of the many American networks carried on Canadian televisions.
The CRTC also regulates radio in Canada, including community radio, where the CRTC requires that at least 15% of each station's output must be locally produced spoken word content.
In a major May 1999 decision on "New Media", the CRTC held that under the Broadcasting Act the CRTC had jurisdiction over certain content communicated over the Internet including audio and video, but excluding content that is primarily alphanumeric such as emails and most webpages. It also issued an exemption order committing to a policy of non-interference.
In May 2011, in response to the increase presence of Over-the-Top (OTT) programming, the CRTC put a call out to the public to provide input on the impact OTT programming is having on Canadian content and existing broadcasting subscriptions through satellite and cable.
On October 5, 2011 the CRTC released their findings that included consultations with stakeholders from the telecommunication industry, media producers, and cultural leaders among others. The evidence was inconclusive, suggesting that an increased availability of OTT options is not having a negative impact on the availability or diversity of Canadian content, one of the key policy mandates of the CRTC, nor are there signs that there has been a significant decline of television subscriptions through cable or satellite. However, given the rapid progress in the industry they are working on a more in depth study to be concluded in May 2012.
The CRTC does not directly regulate rates, quality of service issues, or business practices for Internet service providers. However, the CRTC does continually monitor the sector and associated trends. To handle complains, the CRTC was ordered by the Government of Canada to create an independent, industry-funded agency to resolve complaints from consumers and small business retail telecom customers. In July 2007, the Commission for Complaints for Telecom-Television Services (CCTS) opened its doors.
Third Party ISP Access refers to a ruling forcing Cable operators (MSO) to offer Internet access to third party resellers.
The commission currently has some jurisdiction over the provision of local landline telephone service in Canada. This is largely limited to the major incumbent carriers, such as Bell Canada and Telus, for traditional landline service (but not Voice over Internet Protocol (VoIP)). It has begun the gradual deregulation of such services where, in the commission's opinion, a sufficient level of competition exists.
The CRTC is sometimes blamed for the current state of the mobile phone industry in Canada, in which there are only three national mobile network operators – Bell Mobility, Telus Mobility, and Rogers Wireless – as well as a handful of MVNOs operating on these networks. In fact, the commission has very little to do with the regulation of mobile phone service, outside of "undue preference" issues (for example, a carrier offering a superior rate or service to some subscribers and not others without a good reason).
It does not regulate service rates, service quality, or other business practices, and commission approval is not necessary for wireless provider sales or mergers as in the broadcasting industry. Moreover, it does not deal with the availability of spectrum for mobile phone service, which is part of the Industry Canada mandate, nor the maintenance of competition, which is largely the responsibility of The Competition Bureau.
Any transfer of more than 30% of the ownership of a broadcasting licence (including cable/satellite distribution licences) requires advance approval of the commission. One condition normally taken into account in such a decision is the level of foreign ownership; federal regulations require that Canadian citizens ultimately own a majority of a broadcast licence. Usually this takes the form of a public process, where interested parties can express their concerns and sometimes including a public hearing, followed by a commission decision.
While landline and mobile telephone providers must also be majority-owned by Canadians under the federal Telecommunications Act, the CRTC is not responsible for enforcement of this provision. In fact, the commission does not require licences at all for telephone companies, and CRTC approval is therefore not generally required for the sale of a telephone company, unless said company also owns a broadcast licence.
Since 1987, the CRTC has been involved in several notable decisions, some of which led to controversy and debate.
Milestone Radio: In two separate rounds of licence hearings in the 1990s, the CRTC rejected applications by Milestone Radio to launch a radio station in Toronto which would have been Canada's first urban music station; in both cases, the CRTC instead granted licences to stations that duplicated formats already offered by other stations in the Toronto market. The decision has been widely cited as one of the single most significant reasons why Canadian hip hop had difficulty establishing its commercial viability throughout the 1990s. The CRTC finally granted a licence to Milestone in 2000, after a cabinet order-in-council directed the commission to license two new radio stations that reflected the cultural diversity of the Toronto market, and CFXJ-FM launched in 2001.
CHOI-FM: The CRTC announced it would not renew the licence of the popular radio station CHOI-FM in Quebec City, after having previously sanctioned the station for failing to uphold its promise of performance and then, during the years following, receiving about 50 complaints about offensive behaviour by radio jockeys which similarly contravened CRTC rules on broadcast hate speech. Many thousands of the station's fans marched in the streets and on Parliament Hill against the decision, and the parent company of CHOI, Genex Corp., appealed the CRTC decision unsuccessfully to the Federal Court of Canada.
The station was later sold to RNC Media, but instead of renewing its licence the CRTC issued RNC a licence to launch a new radio station on the same frequency.
CBC Newsworld: The CRTC licensed the CBC on November 30, 1987 to provide a national all-news television network. Its competitor applicant, Alberta-based Allarcom, appealed this decision to the House of Commons of Canada. It was overturned and there were questions of whether federal politicians should meddle in CRTC decisions. Because of this the network launch was delayed from September 1, 1988 to July 31, 1989.
RAI International: In Summer 2004, this Italian government-controlled channel was denied permission to broadcast independently in Canada on the grounds that it had acted and was likely to act contrary to established Canadian policies. RAI International's latest politically appointed President (an avowed right wing nationalist and former spokesperson for Giorgio Almirante, the leader of the post-fascist party of Italy) had unilaterally terminated a 20-year-old agreement and stripped all of its 1,500 to 2,000 annual hours of programming from Telelatino (TLN), a Canadian-run channel which had devoted 95% of its prime time schedule to RAI programs for 20 years since TLN was founded.
All Italian-Canadians were denied RAI programming by RAI International's removal of its programming from the Canadian marketplace, a move intended to create a public outcry and a threat that Canadians would resort to using satellite viewing cards obtained via the US in order to watch RAI, even though these cards were either grey market or black market, according to different analyses (see below). Following unprecedented foreign led and domestic political interference with the CRTC's quasi-judicial independent regulatory process, within six months of its original decision, an abrupt CRTC "review" of its policy on third-language foreign services determined to drop virtually all restrictions and adopt a new "open entry" approach to foreign controlled "third language" (non-English, non-French) channels.
Al Jazeera: Was approved by the CRTC in 2004 as an optional cable and satellite offering, but on the condition that any carrier distributing it must edit out any instances of illegal hate speech. Cable companies declared that these restrictions would make it too expensive to carry Al Jazeera. Although no cable company released data as to what such a monitoring service would cost, the end-result was that no cable company elected to carry the station, either, leaving many Arabic-speaking Canadians using free-to-air satellite dishes to watch the station.
The Canadian Jewish Congress has expressed its opinion over possible anti-Semitic incitement on this station and that the restrictions on Al Jazeera are appropriate, while the Canadian B'nai Brith is opposed to any approval of Al Jazeera in Canada. The CRTC ruling applied to Al Jazeera and not to its English-speaking sister network Al Jazeera English, which was launched two years after the ruling.
Fox News Channel: Until 2004, the CRTC's apparent reluctance to grant a digital licence to Fox News Channel under the same policy which made it difficult for RAI to enter the country – same-genre competition from foreign services – had angered many conservative Canadians, who believed the network was deliberately being kept out due to its perceived conservative bias, particularly given the long-standing availability of services such as CNN and BBC World in Canada.
On November 18, 2004, however, the CRTC approved an application by cable companies to offer Fox News Channel on the digital cable tier. Fox commenced broadcasting in Canada shortly thereafter.
Satellite radio: In June 2005, the CRTC outraged some Canadian cultural nationalists (such as the Friends of Canadian Broadcasting) and labour unions by licensing two companies, Canadian Satellite Radio and Sirius Canada to offer satellite radio services in Canada. The two companies are in partnership with American firms XM Satellite Radio and Sirius Satellite Radio respectively, and in accordance with the CRTC decision will only need to offer ten percent Canadian content. The CRTC contends that this low level of Canadian content, particularly when compared to the 35% rule on local radio stations, was necessary because unlicensed U.S. receivers were already flooding into the country, so that enforcing a ban on these receivers would be nearly impossible (see below).
This explanation did not satisfy cultural nationalists, who demanded that the federal cabinet overturn the decision and mandate a minimum of 35% Canadian content. Supporters of the decision argue that satellite radio can only be feasibly set up as a continental system, and trying to impose 35% Canadian content across North America is quite unrealistic. They also argue that satellite radio will boost Canadian culture by giving vital exposure to independent artists, instead of concentrating just on the country's stars, and point to the CRTC's successful extraction of promises to program 10% Canadian content on satellite services already operational in the United States as important concessions. Despite popular perception that the CRTC banned Sirius Canada from broadcasting Howard Stern's program, this is not the case. Sirius Canada in fact initially chose not to air Stern based on the possibility of a future issue with the CRTC, although the company reversed its decision and began offering Howard Stern in 2006.
2008 Ottawa radio licences: On November 21, 2008, federal Minister of Canadian Heritage and Official Languages James Moore issued a statement calling on the CRTC to review its approval of two new radio stations, Frank Torres' CIDG-FM and Astral Media's CJOT-FM, which it had licensed in August 2008 to serve the Ottawa-Gatineau radio market. Moore asked the commission to assess whether the francophone population of the Ottawa-Gatineau area was sufficiently well-served by existing French radio services, and to consider licensing one or more of the French language applications, which included a Christian music station, a community radio station and a campus radio station for the Université du Québec en Outaouais, in addition to or instead of the approved stations. The review ultimately identified a viable frequency for a third station, and CJFO-FM launched in 2010.
Bell Canada usage-based billing: On October 28, 2010, the CRTC handed down its final decision on how wholesale customers can be billed by large network owners. Under the plan which starts within 90 days, Bell will be able to charge wholesale service providers a flat monthly fee to connect to its network, and for a set monthly usage limit per each ISP customer the ISP has. Beyond that set limit, individual users will be charged per gigabyte, depending on the speed of their connections.
Customers using the fastest connections of five megabits per second, for example, will have a monthly allotment of 60 GB, beyond which Bell will charge $1.12 per GB to a maximum of $22.50. If a customer uses more than 300 GB a month, Bell will also be able to implement an additional charge of 75 cents per gigabyte. In May 2010, the CRTC ruled that Bell could not implement its usage-based billing system until all of its own retail customers had been moved off older, unlimited downloading plans. The requirement would have meant that Bell would have to move its oldest and most loyal customers.
The CRTC also added that Bell would be required to offer to wholesale ISPs the same usage insurance plan it sells to retail customers. Bell appealed both requirements, citing that the rules do not apply to cable companies and that they constituted proactive rate regulation by the CRTC, which goes against government official policy direction that the regulator only intervene in markets after a competitive problem has been proven. In Thursday's decision, the CRTC rescinded both requirements, thereby giving Bell the go-ahead to implement usage-based billing. This ruling according to Teksavvy handcuffs the competitive market. This has been asked by Stephen Harper and Parliament to have the decision reviewed. According to a tweet by Industry Minister Tony Clement, unless the CRTC reverses this decision, the government will use its override power to reverse the decision.
While an exact number has not been determined, thousands of Canadians have purchased and used what they contend to be grey market radio and television services, licensed in the United States but not in Canada. Users of these unlicensed services contend that they are not directly breaking any laws by simply using the equipment. The equipment is usually purchased from an American supplier (although some merchants have attempted to set up shop in Canada) and the services are billed to an American postal address. The advent of online billing and the easy availability of credit card services has made it relatively easy for almost anyone to maintain an account in good standing, regardless of where they actually live.
Sec. 9(1)(c) of the Radiocommunication Act creates a prohibition against all decoding of encrypted programming signals, followed by an exception where authorization is received from the person holding the lawful right in Canada to transmit and authorize decoding of the signal. This means receiving the encrypted programming of DishNetwork or DirecTV, even with a grey market subscription, may be construed as unlawful (this remains an unresolved Constitutional issue).
Notwithstanding, possession of DishNetwork or DirecTV equipment is not unlawful as provided by The Radiocommuncation Act Section 4(1)(b), which states:
"No person shall, except under and in accordance with a radio authorization, install, operate or possess radio apparatus, other than (b)a radio apparatus that is capable only of the reception of broadcasting and that is not a distribution undertaking. (radio apparatus" means a device or combination of devices intended for, or capable of being used for, radiocommunication)."
Satellite radio poses a more complicated problem for the CRTC. While an unlicensed satellite dish can often be identified easily, satellite radio receivers are much more compact and can rarely be easily identified, at least not without flagrantly violating provisions against unreasonable search and seizure in the Canadian Charter of Rights and Freedoms. Some observers argued that this influenced the CRTC's June 2005 decision to ease Canadian content restrictions on satellite radio (see above).
The CRTC is run by up to 13 full-time members (including the chairman, the vice-chairman of broadcasting, and the vice-chairman of telecommunications) appointed by the Cabinet for renewable terms of up to five years. However, unlike the more directly political appointees of the American Federal Communications Commission, the CRTC is an arms-length regulatory body with more autonomous authority over telecommunications. For example, the CRTC's decisions rely more on a judiciary process relying on evidence submitted during public consultations, rather than along party lines as the American FCC is prone to do.
The CRTC Interconnection Steering Committee (CISC) assists in developing information, procedures and guidelines for the CRTC's regulatory activities. | [

] | The Canadian Radio-television and Telecommunications Commission is a public organization in Canada with mandate as a regulatory agency for broadcasting and telecommunications. It was created in 1976 when it took over responsibility for regulating telecommunication carriers. Prior to 1976, it was known as the Canadian Radio and Television Commission, which was established in 1968 by the Parliament of Canada to replace the Board of Broadcast Governors. Its headquarters is located in the Central Building of Les Terrasses de la Chaudière in Gatineau, Quebec. | 2001-07-30T12:55:05Z | 2023-11-07T18:09:32Z | [
