The Tsuu T'ina Nation is a First Nation in Canada. Their territory is located on the Indian reserve Tsuu T'ina Nation 145, whose east side is adjacent to the southwest city limits of Calgary, Alberta. The land area of the reserve is 283.14_km_ (109.32 sq mi), and it had a population of 1,982 in the Canada 2001 Census. The land is a former Canadian Army training camp, active from 1910-1996, when the land was turned over to the Tsuu T'ina Nation. The Tsuu T'ina people have formerly been called the Sarsi or Sarcee, words which are believed to have been derived from a Blackfoot word meaning stubborn ones. This is in reference to territorial conflict between the Tsuu T'ina and the Blackfoot Confederacy. The term is now viewed as offensive by most of the Tsuu T'ina.
