The Chickasaw are a Native American people of the United States, who originally came from the bank of the Tennessee River just west of Huntsville, Alabama. Sometime prior to the first European contact, the Chickasaw moved east, and settled east of the Mississippi. All historical records indicate the Chickasaw lived in northeast Mississippi from the first European contact until they were forced to remove to Oklahoma, where most now live. They are related to the Choctaws, who speak a language very similar to the Chickasaw language, both forming the Western Group of the Muskogean languages. "Chickasaw" is the English spelling of Chikasha , that means "rebel" or "comes from Chicsa". The Chickasaw are divided in two groups: the "Impsaktea" and the "Intcutwalipa". The Chickasaws were one of the "Five Civilized Tribes" forcibly removed to the Indian Territory during the era of Indian Removal. The Chickasaw Nation is the thirteenth largest federally-recognized tribe in the United States.
