Walla Wallas, sometimes Waluulapam and sometimes on this site as Walula, are a Sahaptin-speaking indigenous people that lived primarily along their namesake river. There has been disagreement among historians regarding the nation’s etymology. Stern suggests that it is a diminished form of the Sahaptin wana ‘river’. Wallula or Walula, walúula was their primary settlement just above the mouth of the Walla Walla.
Walla Walla came to be applied by whites to other nations such as the Umatillas. In late 1949, the Umatillas, Cayuses, and Walla Wallas officially became The Confederated Tribes of the Umatilla Indian Reservation, an alliance based their 1855 namesake treaty with Isaac Stevens.[2]Theodore Stern, Handbook of North American Indians: Plateau Vol. 12, ed.
