The Five Native Tribes: Cherokee, Chickasaw, Choctaw, Creek (Muscogee), and Seminole, were sovereign nations forcibly removed from their ancestral homelands in the Southeast to Indian Territory (present-day Oklahoma) during the 1830s. Within these communities, slavery became a part of their social and economic systems, paralleling that of the American South. After the Civil War, 1866 treaties with the United States required each tribe to emancipate and extend citizenship to their Freedmen.
