Project Homeland › Nations

Arapaho Tribe of the Wind River Reservation, Wyoming

Lands ceded to the United States by treaty, law or executive order, 1851–1876, as Charles C. Royce recorded them in 1899 — 379,797 km² in 8 cessions across Colorado, Kansas, Montana, North Dakota, Nebraska, New Mexico, Oklahoma, South Dakota, Wyoming.

A cession records when the United States took title — not the full extent of a homeland, and much land was taken without any treaty. The link between each cession and present-day nations is the one the U.S. Forest Service and the National NAGPRA Program’s dataset records; the nation’s own account comes first.

Named in the treaties as: Arapaho · Sioux · Cheyenne · Northern Cheyenne · Arikara · Assiniboin · Crow · Gros Ventre
