As general terms, Indian Territory, the Indian Territories, or Indian country describe an evolving land area set aside by the United States Government for the relocation of Native Americans who held aboriginal title to their land. In general, the tribes ceded land they occupied in exchange for land grants in an area purchased by the United States federal government from Napoleonic France, the Louisiana Purchase. The concept of an Indian Territory was an outcome of the 18th- and 19th-century policy of Indian removal. After the Civil War, the policy of the government was one of assimilation.
