Sihasapa

The Sihásapa or Blackfoot Sioux are a division of the Lakota people, Titonwan, or Teton.
Sihásapa is the Lakota word for "Blackfoot", whereas Siksiká has the same meaning in the Blackfoot language. As a result, the Sihásapa have the same English name as the Blackfoot Confederacy, and the nations are sometimes are confused with one another.
