Land of the Nez Percè, Blackfoot and Flathead Nations in Montana, recorded 1851 (area 399)

Shape traced from the 1899 maps; approximate. Open on the map

In the record

The area covers about 11 million acres in what is now Montana.

The 1899 record names Séliš (Bitterroot Salish) and Nez Perce (Nimiipuu) as the people of this land.

The record ties this land to 2 agreements: Treaty of Fort Laramie (Horse Creek), 1851 and Lame Bull Treaty (Blackfeet), 1855. Which one ceded it has not been checked yet, so the map dates it by the first.

How it was taken: a treaty or agreement. The treaty text records an agreement among the eight nations and two U.S. commissioners; the cited sources do not describe duress.

Today, Confederated Salish and Kootenai Tribes, Confederated Tribes of the Colville Reservation and Nez Perce Tribe carry the history of the people named here.

Shapes come from C. C. Royce’s 1899 maps as georeferenced by the US Forest Service. They are approximate and are not legal descriptions of land. Royce recorded land the United States treated as ceded; the shape does not show a nation’s territory.
