The Modoc Nation is a federally recognized tribe of Modoc people, located in Ottawa County in the northeast corner of Oklahoma, Modoc and Siskiyou counties in northeast California. The smallest tribe in the state, they are descendants of Captain Jack's band of Modoc people, removed in 1873 after the Modoc Wars from their traditional territory in northern California and southern Oregon. They were exiled to the Quapaw Agency in Indian Territory (now Oklahoma), where they were colocated with the Shawnee people from east of the Mississippi River.
In the 1950s, the federally recognized status of the Klamath Reservation (where other Modoc live) and the Modoc was terminated, ending federal assistance to the two tribes.
