On January 24th, 1848, James Marshall discovered gold at Sutter's Mill in Coloma, California, sparking the California Gold Rush. Over 300,000 people traveled to California seeking gold over the next few years. The Gold Rush transformed California from a sparsely populated territory into a major economic and political force, with its population increasing over tenfold. It also had significant effects on Native Americans living in California and permanently changed the state's social and economic landscape. The Gold Rush ended around 1852 as prospecting became increasingly difficult.
