Who did Chief Joseph's tribe fight?

Chief Joseph was the leader of the Nez Perce tribe, and his people primarily fought against the United States government during the Nez Perce War of 1877. The conflict arose over the U.S. government's attempts to force the Nez Perce onto a reservation in Idaho, which led to a series of battles as Chief Joseph sought to lead his people to safety in Canada. The Nez Perce faced overwhelming military force, ultimately resulting in their surrender after a long and arduous retreat.
