The Tsuutʼina Nation (also Tsu Tʼina, Tsuu Tʼina, Tsúùtínà – "a great number of people"; formerly Sarcee, Sarsi) (Sarsi: Tsúùtʼínà) is a First Nation band government in Alberta, Canada. Their territory today is confined to the Tsuu T'ina Nation 145 reserve, whose east side is adjacent to the southwest city limits of Calgary. 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.[clarification needed] The Tsuutʼina people were formerly called the Sarsi or Sarcee, words which are believed to have been derived from a Blackfoot word meaning "stubborn ones". The two peoples long had conflict over the territory because the Sarcee are on traditional Blackfoot land. Because of its origins from an enemy, the term is now viewed as offensive by most of the Tsuutʼina.[citation needed] From Wikipedia
