Gold Confirmed in California: The Gold Rush Begins
President James K. Polk confirmed in his annual message to Congress on December 5, 1848, that 'the accounts of the abundance of gold in that territory are of such extraordinary character as would scarcely command belief were they not corroborated by authentic reports.' Gold had been discovered at Sutter's Mill in January, but news traveled slowly. Polk's official confirmation triggered the largest mass migration in American history: roughly 300,000 people arrived in California within four years, coming from every continent. San Francisco's population exploded from 200 to 36,000 in two years. California was admitted as a state in 1850, bypassing territorial status entirely. Most miners found little gold. The real fortunes were made by merchants: Levi Strauss selling durable pants, Leland Stanford selling supplies, and Wells Fargo moving money.
