California Gold Rush

24 January 1848

The California Gold Rush was one of the largest mass migrations in American history. After gold was found in the foothills of the Sierra Nevada, news spread across the world, and hundreds of thousands of prospectors, the so-called forty-niners, poured into the territory by sea, by the overland trails and across the Isthmus of Panama. San Francisco grew from a small settlement into a major port almost overnight, and California became a state in 1850 without passing through the usual stage of territorial government. The rush enriched merchants and speculators more reliably than miners, and it brought devastating violence and disease to Native Californian peoples. Hydraulic mining later left lasting damage to rivers and valleys.
