High Quality Content by WIKIPEDIA articles! The Choctaw (alternatively spelled Chahta, Chactas, Chato, Tchakta, Chocktaw, and Chactaw) are a Native American people originally from the Southeastern United States (Mississippi, Florida, Alabama, and Louisiana). The Choctaw language belongs to the Muskogean linguistic group. The Choctaw are descendants of the Hopewellian people and Mississippian culture, who lived throughout the east of the Mississippi River valley and its tributaries. The former built Nanih Waiya, a great earthwork mound about 1,700 years ago that is considered sacred by the Choctaw. The early Spanish explorers of the mid-16th century encountered Mississippian-culture villages and chiefs.
