Tsuutʼina Nation in the context of "Tsuutʼina language"

The Blackfoot Confederacy, Niitsítapi, or Siksikáí'tsitapi (ᖹᒧᐧᒣᑯ, meaning "the people" or "Blackfoot-speaking real people"), is a historic collective name for linguistically related groups that make up the Blackfoot or Blackfeet people: the Siksika ("Blackfoot"), the Kainai ("Many Chiefs") or Blood, and two sections of the Peigan or Piegan or Piikani ("Splotchy Robe") – the Northern Piikani (Aapátohsipikáni) and the Southern Piikani (Amskapi Piikani or Pikuni). Broader definitions include groups such as the Tsúùtínà (Sarcee) and A'aninin (Gros Ventre) who spoke quite different languages but allied with or joined the Blackfoot Confederacy.

Historically, the member peoples of the Confederacy were nomadic bison hunters and trout fishermen, who ranged across large areas of the northern Great Plains of western North America, specifically the semi-arid shortgrass prairie ecological region. They followed the bison herds as they migrated between what are now the United States and Canada, as far north as the Bow River. In the first half of the 18th century, they acquired horses and firearms from white traders and their Cree and Assiniboine go-betweens. The Blackfoot used these to expand their territory at the expense of neighboring tribes.

Tsuu T'ina Nation 145 (Tsuut'ina: Tsúùtʾínà, lit. 'a great number of people', 'many people'; or 'beaver people') is an Indian reserve of the Tsuut'ina Nation in southern Alberta, Canada, created by Treaty 7.

The reserve is located in the Calgary Region, bordering the City of Calgary to the northeast, east and southeast, the Municipal District of Foothills No. 31 to the south and Rocky View County to the west and north. It is bound by Tsuut'ina Trail to the east, 146 Avenue SW to the south and Highway 22 and Wintergreen Road (Range Road 52) to the west, while Highway 8 is generally within 0.8 km (0.5 mi) of the reserve's northern boundary. The Hamlet of Bragg Creek is adjacent to the southwest corner of the reserve within Rocky View County across Highway 8.
