- The Treaty of Point Elliott of 1855, or the Point Elliott Treaty,—also known as the Treaty of Point Elliot / Point Elliot Treaty—is the lands settlement treaty between the United States government and the Native American tribes of the greater Puget Sound region in the recently formed Washington Territory (March 1853), one of about thirteen treaties between the U.S. and Native Nations in what is now Washington. The treaty was signed on January 22, 1855, at Muckl-te-oh or Point Elliott, now Mukilteo, Washington, and ratified 8 March and 11 April 1859. Between the signing of the treaty and the ratification, fighting continued throughout the region. Lands were being occupied by European-Americans since settlement in what became Washington Territory began in earnest from about 1845.
