Why Did Thousands Migrate to California in 1848? The Gold Rush

1848: Gold Discovered at Sutter's Mill → Mass Migration

James Marshall found gold flakes at Sutter's Mill (Coloma, CA) in January 1848. News spread globally.

🌊 The Gold Rush (1848–1855)

• 300,000+ people arrived by land (California Trail) and sea (Cape Horn, Panama).
• "Forty-Niners" (1849 peak): Americans, Chinese, Chileans, Mexicans, Europeans, Australians.
• San Francisco exploded: 1,000 → 25,000 in 1849.
• California statehood fast-tracked (1850).

⛏️ Reality Check

• Most miners made little; merchants (Levi Strauss, Sam Brannan) got rich.
• Native population decimated (disease, violence, displacement).
• Environmental damage: hydraulic mining, mercury.

Gold = catalyst. Migration = transformative event reshaping West, nation, world.
