In 1848, gold was discovered in California, sparking the California Gold Rush. Word of the discovery quickly spread, with thousands traveling from around the United States and the world to seek their fortune in the gold fields. While some struck riches, most found only difficult living conditions with long hours of backbreaking work for little pay amid disease and hardship. Though the surface gold was soon depleted, the Gold Rush transformed California and contributed to the wider settlement of the American West.
