The Chickasaw (/ˈtʃɪkəsɔː/ CHIK-ə-saw) are an Indigenous people of the Southeastern Woodlands, United States. Their traditional territory was in northern Mississippi, northwestern and northern Alabama, western Tennessee and southwestern Kentucky. Their language is classified as a member of the Muskogean language family. In the present day, they are organized as the federally recognized Chickasaw Nation.
Chickasaw people have a migration story in which they moved from a land west of the Mississippi River to reach present-day northeast Mississippi, northwest Alabama, and into Lawrence County, Tennessee. They had interaction with French, English, and Spanish colonists during the colonial period. The United States considered the Chickasaw one of the Five Civilized Tribes of the Southeast, as they adopted numerous practices of European Americans. Resisting European-American settlers encroaching on their territory, they were forced by the U.S. government to sell their traditional lands in the 1832 Treaty of Pontotoc Creek and move to Indian Territory (Oklahoma) during the era of Indian removal in the 1830s.
