The Puget Sound War was an armed conflict that took place in the Puget Sound area of the state of Washington in 1855–56, between the United States Military, local militias and members of the Native American tribes of the Nisqually, Muckleshoot, Puyallup, and Klickitat. Another component of the war, however, were raiders from the Haida and Tlingit who came into conflict with the United States Navy during contemporaneous raids on the native peoples of Puget Sound.
