Assiniboia
Assiniboia
Early region, western Canada. Named for the Assiniboin Indians, it was an area with indefinite boundaries, controlled by the Hudson's Bay Co. c. 1811–70. It included present-day southern Manitoba and, until 1818, the Red River Valley in present-day North Dakota and Minnesota. It was incorporated into Manitoba in 1870. In 1882 the Canadian government created another district of Assiniboia as part of the old Northwest Territories. In 1905 this district was divided between Alberta and Saskatchewan.
