The Confederated Tribes of Warm Springs is a federally recognized confederation of Native American tribes who currently live on and govern the Warm Springs Indian Reservation in the U.S. state of Oregon.
The confederation consists of three tribes of the Pacific Northwest:
Before becoming the Confederated Tribes of Warm Springs the three tribes; Wasco, Warm Springs, and Paiute, lived along the Columbia River and Cascade Mountains. They all spoke different languages and had their own custom ways. The Warm Springs and Wasco tribes traded and conversed frequently while the Paiute's language prevented them from frequent contact because it was foreign to the other tribes. In 1800, immigrants from the east first started to arrive, by 1852 around 12,000 settlers crossed the tribes' territories each year. The Warm springs and Wasco signed a treaty with Joel Palmer in 1855 after dealing with their traditional ways of life being disrupted by the settlers for many years. By signing the treaty the Wasco and Warm Springs tribes relinquished 10 million acres of land to the United States and kept 640,000 acres for their own use. The first people from the Paiute tribe to arrive on reservation were the 38 Paiutes that were forced to move onto the Warm Springs Reservation from the Yakama Reservation in 1879. Soon more arrived and they eventually became a permanent part of the Warm Springs Reservation. The Confederated Tribes adopted a constitution in 1938, after the construction of Bonneville Dam flooded the major fishing site at Cascades Rapids. Upon receiving a $4 million settlement in compensation for the 1957 flooding of Celilo Falls by the construction of The Dalles Dam, the Tribes used part of the sum to build the Kah-Nee-Ta resort, which opened in 1964.
In 2001, members of the Confederated Tribes persuaded the Oregon Legislative Assembly to pass a bill mandating that the word squaw be changed in numerous place names.
