Blackfoot Confederacy

The Blackfoot Confederacy, Niitsítapi, or Siksikáí'tsitapi, is a historic collective name for linguistically related groups that make up the Blackfoot or Blackfeet people: the Siksika ("Blackfoot"), the Kainai or Blood, and two sections of the Peigan or Piegan or Piikani – the Northern Piikani (Aapátohsipikáni) and the Southern Piikani. Broader definitions include groups such as the Tsúùtínà (Sarcee) and A'aninin who spoke quite different languages but allied with or joined the Blackfoot Confederacy.
