The Choctaw Nation
Treaties negotiated between the federal government and the Choctaw Indian Tribe provided a vehicle for the transfer of millions of acres of Indian lands to the United States. These lands became an economic base, as well as a source of power, for the U.S. in the westward expansion movement during the 18th and 19th centuries. Beginning with the Hopewell Treaty of 1786 and others continuing through 1866 approximately 25,385,238 million acres of Indian lands were ceded to the U.S. in exchange for approximately 5,000,000 acres of land in the Indian Territory. With the Treaty of Dancing Rabbit Creek (September 15 (27) 1830, remaining Choctaw lands in Mississippi were ceded thus paving the way for the Choctaw Nation removal to Indian Territory in Oklahoma.
