The Indian Territories, or Indian Country describe an evolving land area set aside by the United States
Government for the relocation of the indigenous peoples of the Americas 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 Napoleon, the Louisiana Purchase. The
concept of an Indian Territory was an outcome of the 18th- and 19th-century policy of Indian removal.
After the United States Civil War the policy of the government was one of assimilation.
The term Indian Reserve describes lands the British government set aside for indigenous tribes
between the Appalachian Mountains and the Mississippi River in the time before the Revolutionary War.
