Assiniboia is a name derived from the Assiniboine, an Indigenous people. The name Assiniboia applied to two political units in the 19th century. The first was a district centred on the forks of the Red and Assiniboine rivers — which became the site of the Red River Resistance (1869–70) — forerunner to the province of Manitoba. The second was a provisional district of the ever-changing North-West Territories (1870–1905). Two political constituencies (one federal and one Manitoban), a rural municipality (in Manitoba), and a town (in Saskatchewan) have also been called Assiniboia.
