Oklahoma
The name Oklahoma comes from the Choctaw phrase okla humma. This means red (humma) people (okla). Choctaw Chief Allen Wright gave it that name in 1866 during treaty talks with the federal government about the use of Indian Territory. He dreamed of an all-Indian state with power held by the United States Superintendent of Indian Affairs. Okla humma was a phrase in the Choctaw language that meant the same as the English word Indian. It was used to describe the Native American people all together. Oklahoma later became the de facto name for Oklahoma Territory. It was officially accepted in 1890, two years after the area was opened to white settlers.
