summaryShort: James W. Marshall's discovery of gold at Sutter's Mill on January 24, 1848, triggered a mass migration of fortune seekers to California that reshaped the American West.
summaryLong: |-
  On January 24, 1848, James W. Marshall found shiny flakes in the tailrace of a sawmill he was building for John Sutter along the American River near Coloma, California. Nobody expected it to change everything. By the end of that year, word had spread far enough that the first organized parties of gold seekers were already heading west. By 1849—the year that gave them their name, the "forty-niners"—the trickle became a flood. Some 300,000 people, many of them young men with nothing to lose, abandoned their lives in the eastern United States, crossed the continent by wagon or sailed around Cape Horn, all chasing the possibility of instant wealth.

  The Gold Rush didn't happen in a vacuum. It collided directly with the roughly 150,000 Native Americans already living in California. The impact was catastrophic. Prospectors, merchants, and settlers brought disease, violence, and displacement. The California indigenous population fell to around 30,000 by 1860—a collapse driven by murder, starvation, and epidemics. The rush also accelerated statehood itself. California's population swelled so rapidly that it demanded admission to the Union; it entered in 1850 as part of the Compromise of 1850, a deal that temporarily papered over the growing slave-state divide.

  Most prospectors never struck it rich. Prices for food, tools, and supplies in the mining camps were absurd—a dozen eggs cost a dollar when eggs were scarce. The real fortunes often went to merchants and speculators who sold picks, shovels, and beans to desperate miners, or to larger operations that consolidated claims and used organized labor. Yet the Gold Rush did populate the West. Sacramento, San Francisco, and other settlements mushroomed from nothing. By 1852, California was producing roughly 4 million ounces of gold per year—roughly one-quarter of global supply at the time.

  The rush peaked in the early 1850s and then settled into a slower, more industrial affair as placer mining (panning and simple techniques) gave way to hydraulic mining and quartz extraction. By the 1860s, the desperate frontier phase was mostly over, replaced by corporate operations and established towns. But the initial explosion—the mad scramble from 1848 to 1855—had already reshaped the map, the demography, and the political balance of the United States.
lede: "On January 24, 1848, a carpenter named James Marshall found gold in a California stream while building a sawmill. The discovery touched off one of history's largest mass migrations: roughly 300,000 people—mostly young men—rushed west over the following decade, hoping to strike it rich. Most failed, but the flood of settlers transformed California from a remote frontier into a booming state, though at devastating cost to the Native Americans already living there."

zeitgeistNote: The Gold Rush emerged during an era of Manifest Destiny ideology, when American expansion westward was framed as inevitable national destiny. European revolutions were sweeping across 1848 simultaneously, but American attention fixated on California's hills. Dime novels and newspaper dispatches mythologized overnight riches and frontier freedom, attracting fortune-seekers but also encoding racial hierarchies that privileged white American miners over Chinese, Mexican, and Indigenous laborers. The Rush crystallized the fantasy of the self-made American fortune that would dominate the nation's imagination for generations.

impactStatement: James Marshall's discovery of gold at Sutter's Mill on January 24, 1848, triggered the largest migration in American history, fundamentally reshaping the West's demographics, infrastructure, and political balance. Within four years, over 300,000 people flooded California, transforming it from a remote Mexican territory into a booming state that accelerated U.S. continental expansion and destabilized the fragile sectional compromise over slavery.
