The Osage Nation, Oklahoma — lands ceded, 1808–1870

Lands ceded to the United States by treaty, law or executive order, 1808–1870, as Charles C. Royce recorded them in 1899 — 416,355 km² in 7 cessions across Arkansas, Kansas, Missouri, Oklahoma.

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.
