Region: Plains

In the record

The United States made 6 treaties and agreements that name Omaha as a party, from Maha (Omaha) at Portage des Sioux (1815) to Omaha at Washington, DC (1865).

C. C. Royce’s 1899 schedule records 11 cessions of land from Omaha: about 21 million acres by this atlas’s estimate, counting overlaps once. 6 of them came through treaties made under documented pressure. The largest was Land of the Iowa, Medewakanton and others in Iowa, Minnesota and Missouri, ceded 1830 (area 151), about 11 million acres, ceded under Treaty of Prairie du Chien (1830), Sauk, Fox, Sioux, Omaha, Iowa, Oto, Missouri.

One court case turned on its rights: Nebraska v. Parker.

Today, Omaha Tribe of Nebraska carries this history, as their own pages or research records say.
