Oklahoma ( ; Cherokee: "Asgaya gigageyi" / ᎠᏍᎦᏯ ᎩᎦᎨᏱ; Pawnee: "Uukuhuúwa", Cayuga: "Gahnawiyoˀgeh") is a state in the South Central region of the United States.  It is the 20th-most extensive and the 28th-most populous of the 50 United States.  The state's name is derived from the Choctaw words "okla" and "humma", meaning "red people."  It is also known informally by its nickname, "The Sooner State," in reference to the non-Native settlers who staked their claims on the choicest pieces of land before the official opening date and the Indian Appropriations Act of 1889, which opened the door for white settlement in America's Indian Territory.  The name was settled upon statehood.  Oklahoma Territory and Indian Territory were merged and Indian was dropped from the name.
