The California Historical Society (CHS) was the official historical society of California, until it dissolved and transferred its collections to the Stanford University Libraries in an agreement that was announced in January 2025. Founded in 1871 by a group of prominent Californian intellectuals at Santa Clara University, the Society was designated as the California state historical society in 1979. Although the Society was based in San Francisco, it hosted exhibits across California.
