During the Indian Removal era, the Choctaw ceded millions of acres of their territory, including Nanih Waiya, to the United States under the Treaty of Dancing Rabbit Creek, drawn up September 15–27, 1830. In the 1840s, the Choctaw Claims Commission of the United States investigated violations of the treaty by U.S. citizens. J.F.H. Claiborne later wrote about the investigations, "Many of the Choctaws examined... regard this mound as the mother, or birth-place of the tribe, and more than one claimant declared that he would not quit the country as long as Waiya remained."
