Answer:
These early gold-seekers, called "forty-niners," traveled to California by sailing ship and in covered wagons across the continent, often facing substantial hardships on the trip. While most of the newly-arrived were Americans, the Gold Rush also attracted tens of thousands from Latin America, Europe, Australia and Asia.
At first, the prospectors retrieved the gold from streams and riverbeds using simple techniques, such as panning, and later developed more sophisticated methods of gold recovery that were adopted around the world. Gold worth billions of today's dollars was recovered, leading to great wealth for a few; many, however, returned home with little more than they started with.
The effects of the Gold Rush were substantial. San Francisco grew from a tiny hamlet of tents to a boomtown, and roads, churches, schools and other towns were built. A system of laws and a government were created, leading to the admission of California as a state in 1850. New methods of transportation developed as steamships came into regular service and railroads were built. The business of agriculture, California's next major growth field, was started on a wide scale throughout the state. However, the Gold Rush also had negative effects: Native Americans were attacked and pushed off traditional lands, and gold mining caused environmental harm.
The Gold Rush started at Sutter's Mill, near Coloma on January 24, 1848. James W. Marshall, a foreman working for Sacramento pioneer John Sutter found pieces of shiny metal in the tailrace of a lumber mill Marshall was building for Sutter, along the American River. Marshall quietly brought what he found to Sutter, and the two of them privately tested the findings. The tests showed Marshall's particles to be gold. Sutter was dismayed by this, and wanted to keep the news quiet because he feared what would happen to his plans for an agricultural empire if there were a mass search for gold. However, rumors soon started to spread and were confirmed in March 1848 by San Francisco newspaper publisher and merchant Samuel Brannan. The most famous quote of the California Gold Rush was by Brannan; after he hurriedly set up a store to sell gold prospecting supplies, Brannan strode through the streets of San Francisco, holding aloft a vial of gold, shouting "Gold! Gold! Gold from the American River!"
On August 19, 1848, the New York Herald was the first major newspaper on the East Coast to report that there was a gold rush in California; on December 5, President James Polk confirmed the discovery of gold in an address to Congress. Soon, waves of immigrants from around the world, later called the "forty-niners," invaded the Gold Country of California or "Mother Lode." As Sutter had feared, he was ruined; his workers left in search of gold, and squatters invaded his land and stole his crops and cattle.
