Land area
Land of the Sioux (Wahpeton and Sisseton Bands) in North Dakota and South Dakota, ceded 1891 (area 496)
- 1867
Set aside as a reservation
- 1891
Ceded to the United States
The 1899 record: “Confirms agreement with these Indians by which they cede to the U. S. all the unallotted lands of their (Lake Traverse) reservation”
In the record
Set apart at Lake Traverse for the Sisseton and Wahpeton Sioux by the 1867 treaty; the land not allotted to individuals was ceded in an agreement Congress confirmed in March 1891. The area covers about 963 thousand acres in what is now North Dakota and South Dakota.
The 1899 record names Sioux (as named in treaty records), Sisseton and Wahpeton as the people of this land.
How it was taken: a treaty or agreement. The treaty text records a negotiated right-of-way cession and reservations, with a preamble tying it to Congress's earlier confiscation of annuities and reservations.
Today, Cheyenne River Sioux Tribe, Crow Creek Sioux Tribe, Flandreau Santee Sioux Tribe of South Dakota, Assiniboine and Sioux Tribes of the Fort Peck Indian Reservation, Montana, Lower Brule Sioux Tribe, Lower Sioux Indian Community in the State of Minnesota and 10 more carry the history of the people named here.
