Oklahoma Constitution

The Constitution of the State of Oklahoma is the governing document of the U.S. State of Oklahoma. Adopted in 1907, Oklahoma ratified the United States Constitution on November 16, 1907, as the 46th U.S. state. At its ratification, the Oklahoma Constitution was the longest governing document of any government in the world. All U.S. state constitutions are subject to federal judicial review; any provision can be nullified if it conflicts with the U.S. Constitution.

The constitution has been regularly amended, beginning with an amendment approved in the same election in which it was ratified. More than 150 constitutional amendments have been approved by Oklahoma voters.

From 1890 onward, the land that now forms the State of Oklahoma was made up of the Oklahoma Territory (to the west), and the Indian Territory (to the east). Indian Territory, as its name suggests, had a large Native American population; the territory itself had been reduced over time to its then size.

The movement to secure statehood for Indian Territory began in 1902 with a convention in Eufaula, consisting of representatives of the "Five Civilized Tribes". The representatives met again in 1903 to organize a constitutional convention.

The Sequoyah Constitutional Convention met in Muskogee, on August 21, 1905. General Pleasant Porter, Principal Chief of the Creek Nation, was selected as president of the convention. The elected delegates decided that the executive officers of the Five Civilized Tribes would also be appointed as vice-presidents: William Charles Rogers, Principal Chief of the Cherokees; William H. Murray, appointed by Chickasaw Governor Douglas H. Johnston to represent the Chickasaws; Chief Green McCurtain of the Choctaws; Chief John Brown of the Seminoles; and Charles N. Haskell, selected to represent the Creeks (as General Porter had been elected President).
