The Confederated Tribes of the Colville Reservation (Okanagan: sx̌ʷy̓ʔiłpx sqlxʷúlaʔxʷ)[1] is the federally recognized tribe that controls the Colville Indian Reservation, which is located in northeastern Washington, United States.
Eight of these related bands are the names of rivers that flow off of the eastern slopes of the North Cascades or the Okanogan Highlands.
The Nez Perce are the descendants of Chief Joseph band which came from Northeast Oregon.
As part of the conditions of surrender, Chief Joseph and his band were not allowed to return to their home in Oregon and were eventually re-located to the Colville reservation after the so-called "Flight of the Nez Perce" in 1877.
Later the reservation was reduced, and some of the best lands were excluded, made available for settlement by European Americans.
