Gold Chains: The Hidden History of Slavery in CaliforniaInteractive site by ACLU of Northern California that explores the histories of slavery in California. "Laws were passed to force Native people into servitude, while authorities actively encouraged the slaughter of tribes across the state. African Americans toiled as slaves in the mines during the Gold Rush and beyond even though the state constitution banned slavery. Through narratives, public records, archival material and images, this project exposes California’s hidden history and its legacy in the state’s courts, culture, and conscience."
