The Chickasaw received $3 million U.S. dollars from the United States for their lands east of the Mississippi River. In 1836, the Chickasaw agreed to purchase land in Indian Territory from the Choctaw. They paid the Choctaw $530,000 for the western part of their land. For nearly 30 years, the US did not pay the Chickasaw the $3 million it owed them for their territory in the Southeast.
