The Yakima War (1855–1858), also referred to as the Plateau War or Yakima Indian War,^[1] was a conflict between the United States and the Yakama, a Sahaptian-speaking people of the Northwest Plateau, then part of Washington Territory, and the tribal allies of each. It primarily took place in the southern interior of present-day Washington. Isolated battles in western Washington and the northern Inland Empire are sometimes separately referred to as the Puget Sound War and the Coeur d'Alene War, respectively.
