The California Gold rush began in 1848, when James W. Marshall found gold at Sutter's mill in California.
Wow! I found gold!!!
Only a few days later, The Treaty of Guadalupe Hidalgo was passed. This gave California to the US, and ended the Mexican-American War. News of gold brought many new immigrants and settlers from various countries.

Rumors of the discovery of gold were confirmed in March 1848 by San Francisco newspaper publisher Samuel Brannan.
The rumors are true! Gold has been found in the rivers!
People from all over the world came to California in search of gold.
Many people found the gold that they came for, but not everyone was happy. A lot of people ended up going home with less or the same amount of money than they came with.
The population of San Francisco grew from a mere 200 colonists to about 36,000.
