California Gold Rush: History, Facts & Effects

Instructor: Christopher Sailus

Chris has an M.A. in history and taught university and high school history.

In this lesson we explore the California Gold Rush, which spurred the largest mass migration in U.S. History, where hundreds of thousands of people left their homes to become prospectors in California.

Migration

Many of the animals we see every day migrate long distances on a regular basis. Most birds fly south for the winter and north for the summer trying to remain in a temperate climate, and whales often swim from one pole to another for mating season.

People, on the other hand, are far more sedentary. With the exception of a few nomadic tribes that still exist today, it generally takes a lot to get people to uproot themselves, and it certainly takes a momentous event to move thousands of people in the same direction. In January 1848, the discovery of gold at Sutter's Mill by James Marshall was such an event, sparking the mid-nineteenth century California Gold Rush.

History

James Marshall first found gold in the well of the water wheel at the site of Sutter's Mill along the American River settlement set up by John Sutter in the Sacramento River Valley. News of the discovery quickly spread throughout the United States and abroad. Hundreds of thousands rushed to the California Territory in the next few years in search of gold. So many migrated to the territory in 1849 that the migrants were given the nickname, 'forty-niners,' a name which survives today as the name of San Francisco's professional football team.

Though estimates vary wildly, somewhere between 300,000 and 1,000,000 people from all over the world migrated in just over a decade. Some of these settlers got rich, finding huge sums of gold, such as the single gold nugget uncovered in 1859 near Magalia in Butte County, California, that weighed in at 54 pounds. Likewise, the largest deposit of gold ever found in California was discovered in 1854 in Carson Hill, California, and it was a huge lode weighing a whopping 195 pounds!

Regardless of a few outlandish finds, the reality for many of the Gold Rush migrants was far bleaker. The vast majority of these new prospectors found little or no gold panning the rivers and digging the soil of California. Most returned home far worse financially than when they had migrated to California.

Life in the California gold fields was hard. The boomtowns, which surrounded the gold fields, had been constructed almost literally overnight, and many were lawless places where stealing, murder, gambling, and prostitution were rampant.

With such a huge migration of people, all intent on striking it rich by finding gold, what 'easy' gold there was to find was quickly found. By 1855, most of the surface gold had been found, and the prospectors that remained were forced into the rivers. By 1864, these reserves, too, were depleted, and what gold remained was largely sub-surface and only accessible with the use of heavy mining equipment and large tracts of land often requiring expensive land claims.

Effects

The California Gold Rush is one of the largest mass migrations in the history of the world and the largest in U.S. history. Such a massive migration of people caused severe demographic changes in California, which had only been formally acquired by the U.S. in 1846 during the Mexican-American War. Prior to the Gold Rush, San Francisco had been a small port village of somewhere between 200 and 2,000 inhabitants. Within months of the discovery of gold in California Territory, the sleepy port town ballooned in size. By 1850, some estimate the city's population had risen to over 20,000!
