The Koi people were among the Southeastern Pomo who lived in north-central California for millennia. They fished, hunted, and gathered. In the 19th century, European-Americans rapidly flooded Pomo lands. The US government signed two treaties with Pomos in 1851–1852 which defined Pomo territory; however, these treaties were never ratified by congress. In 1856, the US government forcibly removed many Pomo people to a reservation in Mendocino County; however, the Koi remained on their island.
In 1870, Koi people attended a historic Ghost Dance. By 1871, their homes had been burned and destroyed by European-Americans. Disease, enslavement, and murder greatly reduced their population. The federal government secured a parcel of land called Purvis Flat, which became the Lower Lake Rancheria, for the homeless Koi people. In Bureau of Indian Affairs then declared the land "uninhabitable" in 1937; however, the BIA reversed itself and demanded that Koi people had to live on the land or lose their rights to it. Seven tribal families lived on the rancheria in 1950. In 1956, the tribe sold the land to Lake County to use as an airport; however, the federal government never terminated their recognition of the tribe. The BIA finally reaffirmed tribal recognition of the Lower Lake Rancheria on 29 December 2000.
