The California Gold Rush

In 1848, California had recently been annexed by the United States. The discovery of a soft, shiny metal in January of that year would bring about one of the region’s most profound and lasting transformations.

A Land of Minerals

California is a region rich in minerals and metals, like iron, copper, mercury and also gold. Under Spanish rule, Franciscan missionaries learned about gold in California from Native Americans, but they kept their knowledge secret. They know that the allure of gold and could draw all types of treasure seekers bent on becoming rich.

James Marshall Discovers Gold

On Jan. 24, 1848, James Wilson Marshall saw an unusual shine coming off of rocks on the South Fork of the American River, near what is today Sacramento. Originally from New Jersey, Marshall came to California in 1845, took part in the Bear Flag Revolt and served in the Mexican-American War under Capt. John C. Frémont. During that time, he met John Augustus Sutter, the Swiss adventurer who had built a fort near the river. 

Sutter asked Marshall to build a sawmill upriver to supply the growing immigrant population around his fort. When Marshall confirmed that what he found was gold, word spread through the local community of American immigrants, and hundreds of people began flocking to the mill site in hopes of striking it rich.

Sam Brannan Announces the Discovery

Sam Brannan, a Massachusetts merchant who ran the store at Sutter’s Fort, spread the news in San Francisco of Marshall’s discovery. Brannan saw the business potential in the excitement he had generated, so he set up a shop to sell gold prospecting supplies. Brannan eventually became one of the richest men in California.

As word about gold spread, Army colonel Richard Mason — the military governor of California — took a trip to the gold fields to see for himself. What he saw astounded him. In August, he sent a report to Washington, D.C., along with samples of the gold discovered there. In December of 1848, President James K. Polk informed Congress that gold had been discovered in California.

Miners Rush In

By early 1849, thousands of people — mostly young men — were coming from all over the U.S. and also from other countries (Latin America, Europe and China) to California to seek gold. These people came to be known as “49ers.” Some came overland, but most went by ship to San Francisco and then made their way inland. Latin Americans from Mexico—especially the mining region of Sonora —as well as Peruvians and Chileans brought with them valuable prospecting knowledge.

The Gold Rush, as it came to be known, had a massive impact on California’s population. Scholars estimate that in 1848, Native Americans in California numbered approximately 150,000, while non-Natives (mostly Spanish-Mexicans) numbered around 8-9000. Three years later, the non-Native American population had grown to 250,000. 

Almost overnight, San Francisco went from being a small port settlement to a bustling city. Sam Brannan and John Augustus Sutter’s son, John Jr.,  founded the city of Sacramento around the ports along the American River. Together with San Francisco, the city became one of the economic centers of the Gold Rush and later became California’s capital.

The Mother Lode

The area of the Mother Lode — the Sierra Nevada foothills where gold was found — became a network of mining camps. Governor Mason decreed that the camps were under federal jurisdiction and open to all, provided they filed the proper paperwork and followed established procedures. 

So a system of “staking claims” developed, in which prospectors would assert legal rights to an area and to the gold found in it. Many settlements sprang up that became established towns known to this day: Nevada City, Grass Valley, Jackson, Murphy’s, Sutter Creek and Sonora. Larger cities such as Stockton and Marysville also sprang up in response to the trade that developed from the Gold Rush. Over the next decade, almost $600 million in gold was shipped from California to the East Coast.

Crime and the Gold Rush

There was very little law enforcement, and high rates of crime, including murder, were common in the gold fields and bigger cities, like Sacramento and San Francisco. People were often accused of crimes and lynched (hanged without the benefit of a trial). In particular, many gold seekers looked with suspicion on Mexican Californians, foreigners like Chinese and Latin Americans, Native Americans and Black people. A high percentage of these groups were the objects of vigilante justice. Louise Clappe, a writer from New Jersey who moved to California during the Gold Rush, wrote a series of letters under the pseudonym “Dame Shirley,” describing many aspects of life in the gold fields, including the vulgarity and violence of much of it.

Native Americans and the Gold Rush

Most of the mining activity took place on the traditional lands of Native Americans. Before the Gold Rush, Native Americans in California greatly outnumbered non-Indians. But with the massive influx of gold seekers after 1848, Native Americans soon became a minority.  In some places, Indians and gold prospectors established relationships of work and trade, but in many places, disputes broke out, and well-armed miners usually had the upper hand. 

New technologies, such as high-pressure hoses, were introduced to make mining more efficient. In a few short years, hillsides were washed away, and mining operations altered rivers and other waterways, affecting the runs of salmon and other fish that Indian tribes relied on. The first few years following the gold rush and statehood were particularly devastating for Native American communities.

The Constitutional Convention and California Statehood

Between 1846 and 1848, the U.S. Army performed the role of government in California. But in 1849, with the population exploding and violence escalating, Gen. Bennett Riley, the military governor of California, proposed holding a constitutional convention in Monterey (the capital of Spanish and Mexican California) in September. 

48 delegates met in Monterey to devise a constitution, which was then published in English and Spanish (the two official languages of California at the time). One of the most important issues was whether to permit slavery in the state. The delegates voted to forbid slavery, but also to prohibit Black people, Chinese and Native Americans from becoming citizens. The borders of the state were reduced and the excluded areas eventually became the states of Arizona, Nevada, Utah and southern Colorado.

In November, there was an election to form a state legislature, elect a civilian governor and elect members to the U.S. Congress. On September 9, 1850, the U.S. Congress voted to accept California into the Union as the 31st state.
