 The southern part of Indian Country (what eventually became the State of Oklahoma) served as the destination for the policy of Indian removal, a policy pursued intermittently by American presidents early in the 19th century, but aggressively pursued by President Andrew Jackson after the passage of the Indian Removal Act of 1830.The Five Civilized Tribes in the South were the most prominent tribes displaced by the policy, a relocation that came to be known as the Trail of Tears during the Choctaw removals starting in 1831.The trail ended in what is now Arkansas and Oklahoma, where there were already many Indians living in the territory, as well as whites and escaped slaves.
