Reservations

Explanation: In 1851, the Treaty of Fort Laramie  restricted Indians to specific areas away from the major trails along the Mississippi River. Then, in 1867, the Treaty of medicine Lodge  was signed, in which most of the Southern plains Indians agreed to live on reservations. However, at the beginning of the reservation movement, Native Americans moved to smaller reservations in Oklahoma.
