Scholars believe the mound was contemporary with such earthworks as Igomar Mound in Mississippi and Pinson Mounds in Tennessee.
Mississippi also recognizes another band, and smaller Choctaw groups are located in Louisiana, Alabama, and Texas. The National Park Service under the Secretary of Interior has posted public notice of the MOWA Choctaw Indian Reservation in Alabama.
The Alabama Choctaw who are federally recognized under 24 C. The Office of the Secretary of Interior issued the MOWA Band of Choctaw Indians its Federal Bureau of Investigations ORI number formally acknowledging the Government to Government relationship in 1999. Federal Court of Appeals was upheld by the United States Supreme Court in 2002. Cushman noted that Choctaw oral history accounts suggested their ancestors had known of mammoths in the Tombigbee River area; this suggests that the Choctaw ancestors had been in the Mississippi area for at least 4,000–8,000 years.
The Choctaw coalesced as a people in the 17th century, and developed three distinct political and geographical divisions: eastern, western and southern.
These different groups sometimes created distinct, independent alliances with nearby European powers.
They never went to war against the United States but they were forcibly relocated in 1831-1833, as part of the Indian Removal, in order for the US to take over their land for development by European Americans.
In the 19th century, the Choctaw were classified by European Americans as one of the "Five Civilized Tribes" because they adopted numerous practices of their United States neighbors.
After the Civil War, the Mississippi, Alabama, and Louisiana Choctaw fell into obscurity for some time.
The Choctaw in Oklahoma no longer considered them part of the tribe.
The Choctaw were the first Native American tribe forced to relocate under the Indian Removal Act. Their early government had three districts, each with its own chief, who together with the town chiefs sat on their National Council.
They appointed a Choctaw Delegate to represent them to the US government in Washington, DC.
During the American Civil War, the Choctaw in both Oklahoma and Mississippi mostly sided with the Confederate States of America.
