Oklahoma State

---

 Oklahoma is a landlocked state in the South Central and Southwestern region of the United States. It  borders Texas to the south and west, Kansas to the north, Missouri to  the northeast, Arkansas to the southeast, New Mexico to the west, and  Colorado to 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. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City. The state's name is derived from the Choctaw words okla, 'people' and humma, which translates as 'red'. Oklahoma  is also known informally by its nickname, "The Sooner State", in  reference to the Sooners, American settlers who staked their claims in  formerly American Indian-owned lands until the Indian Appropriations Act  of 1889 authorized the Land Rush of 1889 opening the land to  settlement.
