The Kichai were most closely related to the Pawnee.  French explorers encountered them on the Red River in Louisiana in 1701.  By the 1830s and 1840s, they lived in Southern and Southwestern Oklahoma with the Wichita and in the Muscogee Creek Nation. 
The Kichai were part of the complex, shifting political alliances of the South Plains. Early Europeans identified them as enemies of the Caddo.  In 1712, they fought the Hainai along the Trinity River;  however, they were allied with other member tribes of the Caddoan Confederacy and intermarried with the Kadohadacho during this time. 
Caddo-Wichita-Delaware lands were broken up to individual allotments in the beginning of the 20th century. Kichai people's allotted lands were mainly in Caddo County, Oklahoma. Forty-seven full-blood Kichai lived in Oklahoma in 1950. There were only four at the end of the 20th century. 
The Kichai are not a distinct federally recognized tribe, but they are instead enrolled in the Wichita and Affiliated Tribes. These tribes live mostly in Southwestern Oklahoma, particularly in Caddo County, to which they were forcibly relocated by the United States Government in the 19th century.
