History In 1855, the U.S. government leased the western part of the formerly reserved Choctaw and Chickasaw Nation lands, which became known as the Leased District. After the Civil War, the two nations were forced to cede the land to the US government under terms of new treaties required because they had been allies of the Confederacy. Under the treaties they were also required to emancipate their slaves and provide them with citizenship in their nations.
