Gold Rush!

An incredible discovery in 1848 helped make California one of the most diverse states and spurred the economic growth of the nation.

Something shiny sparkled in the water. It was January 24, 1848, and the glimmering flakes caught the eye of James W. Marshall. The carpenter was building a sawmill on the American River in what is now Coloma, California. Marshall couldn’t believe what he had just found at the worksite, called Sutter’s Mill.

“It made my heart thump, for I was certain it was gold,” Marshall later recalled.

He was right. Marshall’s discovery 175 years ago set in motion the transformation of California—then newly acquired U.S. land—and the country as a whole. The promise of the precious metal sparked the California Gold Rush, one of the largest in U.S. history. More than 300,000 people headed to the region—some from as far away as China, Australia, and Europe.

“When people learned that gold was available for the taking in California, many thousands traveled there from all over the world to seek their fortunes,” says H.W. Brands, a Gold Rush historian and author.

San Francisco emerged as a major port during the Gold Rush.

Gold Fever

At the time, California was largely rural, part of a swath of land in the West that the U.S. had gained at the end of the (1846-1848). Some Mexican and Spanish settlers called it home, along with about 150,000 people whose ancestors had lived there for thousands of years. 

But the lure of gold quickly changed that. “It opened the American West to large numbers of people much sooner than anyone expected,” says Brands.

Within months, people started arriving by boat from the nearby Oregon Territory, as well as from Mexico, Chile, and Peru. By 1849, tens of thousands of fortune seekers were pouring into California. They became known as the forty-niners. Many also came from the Eastern U.S. in covered wagons and on foot. 

Word even spread to China. The Asian nation had been plagued by war and hardships. About 25,000 people left there for California, which many called gam saan, or gold mountain. This marked the first wave of Asian immigration to the U.S.

Panning for gold was backbreaking work, and with so many competing for riches, conditions were often unsanitary and unsafe. Immigrants from Asia and Latin America, along with Black forty-niners and Indigenous people, faced discrimination and violence from some White prospectors. Local officials imposed a foreign miners’ , which targeted Chinese immigrants in particular. 

But many persevered. Some even went on to open local businesses.

Indigenous people in the area suffered from attacks and diseases brought by forty-niners. By the 1870s, fewer than 30,000 remained. 

“Yet even as newcomers overran their lands, Native people resisted, adapted, and survived,” says historian Aims McGuinness. 

Lasting Impact 

By 1855, the Gold Rush was nearly over. But San Francisco, Sacramento, and other new cities continued to thrive. 

The rapid increase in population paved the way for California to gain statehood in 1850, just two years after becoming U.S. land. (New Mexico and Arizona, which had been acquired at the same time, did not become states until 1912.)

“California’s entry into the United States was a key factor in the growing economic power of the nation,” says Gold Rush expert James Delgado. 

This period fueled the growth of roads and bridges, and eventually the development of the railroad between 1863 and 1869. Many Chinese immigrants who came for gold helped build the railroad. 

Today California is the nation’s most populous state—and one of the most diverse. Gold Rush immigrants “changed the face of California and of the larger country,” says Brands. “Their influence is felt today.”
