The California Gold Rush
A gold rush is a sudden migration to a place where gold has been found, driven by the fact that anyone can pan it out of river gravel without equipment. The rush made California a state in 1850 without passing through territorial status, and it upset the balance between slave and free states immediately. For California's Indigenous people it was catastrophic: the population fell from around 150,000 to under 30,000 in twenty years, through disease, displacement and state-funded massacres — the state paid bounties. Hydraulic mining also buried whole river valleys in debris and produced, in 1884, one of the first environmental judgments in American law.
