The Tsuu T'ina became closely associated and allied with the three tribes, whom , along with the Haanin (Atsina or Gros Ventre) became known as the Blackfoot Confederacy. The Tsuu T'ina hunted, trapped, camped, and travelled with the other tribes. The Tsuu Tina adopted a buffalo hunting way of life, acquiring many cultural traits and institutions from the three "Blackfoot" tribes, whom had been long resident in these lands.
