Tsuutʼina Nation

The Tsuutʼina Nation (Tsuutʼina: Tsúùtʾínà, lit. 'a great number of people', 'many people'; or 'beaver people'), also spelled Tsuu Tʼina or Tsu Tʼina, is a First Nation band government in Alberta, Canada. The Tsuu T'ina Nation 145 reserve is located directly west of Calgary, with its eastern edge directly adjacent to the southwest city limits. Their traditional territory spans a much larger area in southern Alberta. The land area of the current reserve is 283.14 km² (109.32 sq mi), and it had a population of 1,982 in the 2001 Canadian census. The northeast portion of the reserve was used as part of CFB Calgary, a Canadian Army base, from 1910 to 1998. In 2006, the land was returned to the Nation by the Government of Canada.

The Tsuutʼina people were formerly known by the Blackfoot exonym Saahsi, typically spelled Sarcee or less frequently Sarsi. These spellings reflect the fact that the French uvular r is quite similar in pronunciation to the Blackfoot velar h. The original meaning of this term is unclear, but suggested meanings include concepts to do with being 'bold', 'hardy', 'strong-willed', or 'stubborn'. It does not appear to be related to any other modern Blackfoot word.
