Who were the Blackfoot tribe enemies?

The Blackfoot tribe, located in the northern Great Plains of North America, had several historical enemies, primarily the Crow and Shoshone tribes. They also faced conflict with European settlers and other tribes as they expanded their territory and resources. Additionally, the U.S. government and its military became adversaries during the westward expansion and subsequent conflicts over land and resources. These hostilities often stemmed from competition for hunting grounds and trade routes.
