Oklahoma

Oklahoma (; Choctaw: Oklahumma) is a state in the South Central region of the United States, bordered by Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Oklahoma City is the capital and largest city of Oklahoma.

The name of the state is derived from the Choctaw words Okla, meaning ‘people’, and Humma. This translates to’red’. Oklahoma is also known informally by its nickname, “The Sooner State”, in reference to the settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were combined into the State of Oklahoma on November 16, 1907.
