The year 1848 was one of the most pivotal in European history, with unrest sweeping through Europe, horrendous poverty in Ireland, and widespread disillusionment about hopes for prosperity throughout Europe and the East Coast of the United States. Stories about the golden port of San Francisco and the agrarian wealth of the American West filtered east, attracting slow-moving groups of settlers. Ex-sailor Richard Henry Dana extolled the virtues of California in his best-selling novel, Two Years Before the Mast, and helped fire the public's imagination about the territory's bounty, particularly that of the Bay Area.
The first overland party crossed the Sierra and arrived in California in 1841. San Francisco grew steadily, reaching a population of approximately 900 by April 1848, but nothing hinted at the population explosion that was to follow. Historian Barry Parr has referred to the California gold rush as the most extraordinary event to ever befall an American city in peacetime. Even without the lure of gold, San Francisco's winning combination of raw materials, healthful climate, and freedom would eventually have attracted thousands of settlers. But the gleam of the soft metal is said to have compressed 50 years of normal growth into less than 6 months. In 1848, the year gold was discovered, the population of San Francisco jumped from under 1,000 to 26,000. As many as 100,000 more passed through San Francisco in the space of less than a year on their way to the rocky hinterlands where the gold was rumored to be.
If not for the discovery of some small particles of gold at a sawmill that he owned, Swiss-born John Augustus Sutter would have left a far less flamboyant legacy. Despite Sutter's wish to keep the discovery quiet, his employee, John Marshall, leaked word of the discovery to friends. It eventually appeared in local papers, and smart investors on the East Coast took immediate heed. The rush did not start, however, until Sam Brannan, a Mormon preacher and famous charlatan, ran through the streets of San Francisco shouting, "Gold! Gold in the American River!" (Brannan, incidentally, bought up all the harborfront real estate he could and cornered the market on shovels, pickaxes, and canned food just before making the announcement that was heard around the world.)
A world on the brink of change responded almost frantically. The gold rush was on. Shop owners hung GONE TO THE DIGGINGS signs in their windows. Flotillas of ships set sail from ports throughout Europe, South America, Australia, and the East Coast, sometimes nearly sinking with the weight of mining equipment. Townspeople from the Midwest headed overland, and the social structure of a nation was transformed almost overnight. Not since the Crusades of the Middle Ages had so many people mobilized in so short a time. Daily business stopped; ships arrived in San Francisco, and their crews almost immediately deserted. News of the gold strike spread like a plague through every discontented hamlet in the known world.
Although other settlements were closer to the gold strike, San Francisco was the famous name and where gold-diggers disembarked. Tent cities sprang up, and demand for virtually everything skyrocketed. Although some miners actually found gold, smart merchants discovered more enduring business in servicing the needs of the thousands of miners who arrived ill-equipped and ignorant of the lay of the land. Prices soared. Miners, faced with staggeringly inflated prices for goods and services, barely turned a profit after expenses. Most prospectors failed, many died of hardship, and others committed suicide at the alarming rate of 1,000 a year. Yet despite the tragedies, graft, and vice associated with the gold rush, within mere months San Francisco had been forever transformed from a tranquil Spanish settlement into a roaring, boisterous boomtown.
