term came to refer to the legal standing of persons (such as the various "estates of the realm" – noble, common, and clerical), and in particular the special status of the king. The highest estates, generally those with the most wealth and social rank, were those that held power. The word also had associations with Roman ideas (dating back to Cicero) about the "status rei publicae", the "condition of public matters". In time, the word lost its reference to particular social groups and became associated with the legal order of the entire society and the apparatus of its enforcement. The early 16th-century works of Machiavelli (especially The Prince) played a central role in popularizing the use of the word "state" in something similar to its modern sense. The contrasting of church and state still dates to the 16th century. The North American colonies were called "states" as early as the 1630s. The expression ("I am the State") attributed to Louis XIV, although probably apocryphal, is recorded in the late 18th century. Definition There is no academic consensus on the definition of the state. The term "state" refers to a set of different, but interrelated and often overlapping, theories about a certain range of political phenomena. According to Walter Scheidel, mainstream definitions of the state have the following in common: "centralized institutions that impose rules, and back them up by force, over a territorially circumscribed population; a distinction between the rulers and the ruled; and an element of autonomy, stability, and differentiation. These distinguish the state from less stable forms of organization, such as the exercise of chiefly power." The most commonly used definition is by Max Weber who describes the state as a compulsory political organization with a centralized government that maintains a monopoly of the legitimate use of force within a certain territory. Weber writes that the state "is a human community that (successfully) claims the monopoly of the legitimate use of physical force within a given territory." While defining a state, it is important to not confuse it with a nation; an error that occurs frequently in common discussion. A state refers to a political unit with sovereignty over a given territory. While a state is more of a “political-legal abstraction,” the definition of a nation is more concerned with political identity and cultural or historical factors. Importantly, nations do not possess the organizational characteristics like geographic boundaries
