Pawnee Nation of Oklahoma

The Pawnee Nation of Oklahoma is a federally recognized tribe. The Pawnee (Paneassa, Pari, Pariki) are a Native American tribe that historically lived along the Platte, Loup and Republican Rivers in present-day Nebraska. They refer to themselves as "Chaticks-si-Chaticks", meaning "Men of men."

The Pawnee Confederacy was divided into the following four bands:

• Chaui (Grand)
• Kitkehahki (Republican)
• Pitahauerat (Tappage)
• Skidi (Wolf)

The Chaui are generally recognized as being the leading band although each band was autonomous.

The Pawnee ceded territory to the American government in treaties in 1818, 1825, 1833, 1848, 1857, and 1892; in 1857, they settled on a reservation along the Loup River in present-day Nance County, Nebraska. Continual raids from Lakota from the north and west and encroachment from American settlers to the south and east lead to the abandonment of their Nebraska reservation. In 1875 they moved to Indian Territory.
