Confederated Tribes of the Umatilla Indian Reservation Administration

"The Cayuse, Umatilla and Walla Walla people make up the Confederated Tribes of the Umatilla Indian Reservation.

Our three bands were brought together on the Umatilla Indian Reservation, established by a Treaty with the US Government in 1855. We were united as a single tribal government in 1949 when our leaders adopted our Constitution and By-laws.

We currently have over 2,521 tribal members."
