The Klamath Tribes, formerly the Klamath Indian Tribe of Oregon, are a federally recognized confederation of three Native American tribes who traditionally inhabited Southern Oregon and Northern California in the United States: the Klamath, Modoc, and Yahooskin. The tribal government is based in Chiloquin, Oregon. After signing the 1864 treaty, members of the Klamath Tribes moved to the Klamath Reservation. At the time there was tension between the Klamath and Modoc, and a band of Modoc left the reservation to return to Northern California. They were defeated by the US Army after the Modoc War (1872-1873), and were forced to return to Oregon.
