The route of enforced westward exile for many Native Americans. As more settlers moved into Georgia and to the states of Alabama, Mississippi, Louisiana, and Florida in the 1830s, it was US policy forcibly to expel the eastern tribes from their lands and move them to Oklahoma territory west of the Mississippi River. The peoples concerned were the Cherokee, Creek, Choctaw, Chickasaw, and Seminole known as the Five Civilized Tribes. Bad weather, neglect, and limited supplies of food caused much suffering and death before the move was completed and the Trail of Tears closed in 1838. In time, even their new homeland became subject to White incursions.
