[clarification needed] The Cloverdale Rancheria is a community of Pomo Indians, who are indigenous to the region that is now called Sonoma County in northern California.

[3] In the early 20th century, the US government created a system of rancherias, or small reservations, for displaced Californian Indians.

[3] Tillie Hardwick (1924–1999), a Pomo woman, sued the United States in the 1979 over the California Rancheria Act and termination policy.

In 1983 she won the lawsuit, paving the way for 17 California tribes to regain federal recognition, including the Cloverdale Rancheria.

In 1994, tribal landowners were forced by California Department of Transportation to sell their land for a U.S. Route 101 bypass.
