Among the Plains Indians of North America, counting coup is the warrior tradition of winning prestige against an enemy in battle. It is one of the traditional ways of showing bravery in the face of an enemy and involves intimidating him, and, it is hoped, persuading him to admit defeat, without having to kill him. These victories may then be remembered, recorded, and recounted as part of the community's oral, written, or pictorial histories.

The Blackfoot Confederacy, Niitsitapi, or Siksikaitsitapi, 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 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.
