The Blackfoot Confederacy or Niitsítapi (meaning “original people”) is the collective name of three First Nations bands in Alberta, Canada and one Native American tribe in Montana, United States. The US – Canadian international border divided their territory.
The Blackfeet Reservation in Montana is home to the Blackfeet Tribe of Montana, who are primarily Southern Siksika peoples. Of the approximately 15,560 enrolled Blackfeet tribal members, there are about 7,000 living on or near the reservation. About 27% of the enrolled members are at least 3/4 blackfeet. They were originally part of the Canadian tribes, but got split by the US – Canadian border. The US Government changed their name from Blackfoot to Blackfeet, probably because of a clerical error.
