Movement of the “Five Civilized Tribes”
In the 1820s, the federal government adopted a policy of Indian Removal from the eastern United States to the prairies of what are now the states of Oklahoma, Kansas, Nebraska and the Dakotas. At that time, the area was known as the “Great American Desert” due to vast treeless prairies, and was considered too hostile for pioneer settlement.
The Indian Nations in the Old South—Mississippi, Alabama, Georgia, Tennesse, and Florida—were the Cherokee, Chickasaw, Choctaw, Creek, and Seminole. These Nations were relocated to an area later labeled Indian Territory. In 1907 this area became the state of Oklahoma.
The Choctaw Nation was the first to be relocated during a period of 15 years, 1820-1835. They were assigned land covering the southern third of Oklahoma. Beginning in 1837 government officials began prodding the Chickasaw Nation to migrate west into Indian Territory. An agreement between the Choctaw and Chickasaw Nations allowed the Chickasaw to settle on part of the Choctaw land grant. In 1855, the two tribes and the U.S. government agreed to split this area into two sections. The land acquired by the Chickasaw was south-central Oklahoma and included 640 acres and over thirty springs, which would later become Platt National Park.
