The Constitution of California () is the primary organizing law for the U.S. state of California, describing the duties, powers, structures and functions of the government of California. California's constitution was drafted in both English and Spanish by American pioneers, European settlers, and Californios (Hispanics of California) and adopted at the 1849 Constitutional Convention of Monterey, following the American Conquest of California and the Mexican–American War and in advance of California's Admission to the Union in 1850. The constitution was amended and ratified on 7 May 1879, following the Sacramento Convention of 1878–79. The Constitution of California is one of the longest collections of laws in the world, partially due to provisions enacted during the Progressive Era limiting powers of elected officials, but largely due to additions by California ballot proposition and voter initiatives, which take form as constitutional amendments. Constitutional amendments may be proposed by the California Legislature or by popular petition through the exercise of the initiative power by the voters, giving California one of the most flexible legal systems in the world. It is currently the eighth longest constitution in the world. Many of the individual rights clauses in the state constitution have been construed as protecting rights even broader than the United States Bill of Rights in the Federal Constitution. An example is the case of Pruneyard Shopping Center v. Robins, in which "free speech" rights beyond those addressed by the First Amendment to the United States Constitution were found in the California Constitution by the California courts. One of California's most significant prohibitions is against "cruel or unusual punishment," a stronger prohibition than the U.S. Constitution's Eighth Amendment prohibition against "cruel and unusual punishment." History The constitution has undergone numerous changes since its original drafting. It was rewritten from scratch several times before the drafting of the current 1879 constitution, which has itself been amended or revised (see below). In response to widespread public disgust with the powerful railroads that controlled California's politics and economy at the start of the 20th century, Progressive Era politicians pioneered the concept of aggressively amending the state constitution by initiative in order to remedy perceived evils. From 1911, the height of the U.S. Progressive Era, to 1986, the California Constitution was amended or revised over 500 times. The constitution gradually became increasingly bloated, leading to abortive efforts towards a third constitutional convention in 1897, 1914, 1919, 1930, 1934 and
