Project Homeland › Nations

Iowa Tribe of Oklahoma

Lands ceded to the United States by treaty, law or executive order, 1830–1883, as Charles C. Royce recorded them in 1899 — 65,644 km² in 7 cessions across Iowa, Kansas, Minnesota, Missouri, Nebraska, 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.

Named in the treaties as: Iowa · Medewakanton · Missouri · Omaha · Oto · Sauk and Fox · Sioux (Wahpeton and Sisseton Bands) · Wahpekuta
