The Wakamatsu Tea and Silk Farm Colony is believed to be the first permanent Japanese settlement in North America and the only settlement by samurai outside of Japan. The group was made up of 22 people from samurai families during the Boshin Civil War (1868–69) in Japan preceding the Meiji Restoration. The group purchased land from Charles Graner family in the Gold Hill region after coming to San Francisco in 1869. Though the group was able to successfully show their produce during the 1869 California State Agricultural Fair in Sacramento and the 1870 Horticultural Fair in San Francisco, the farm as a Japanese colony only existed between 1869 and 1871. Okei Ito, the first known Japanese woman to be buried on American soil, has her grave on the land. The Veerkamp family purchased the farm following the withdrawal of financial support from financier Matsudaira Katamori (1835–93). In 1969, the same year as the Japanese American centennial, Ronald Reagan, then governor of California, proclaimed the colony to be California Historical Landmark No. 815. The family preserved the heritage of the farm and Okei's grave for 137 years until the American River Conservancy purchased the land in November 2010, with the National Park Service placing the site on the National Register of Historic Places at a level of "national significance". American River Conservancy offers private and public tours of the property, including Okei Ito's gravesite.

The California gold rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation, and the California genocide. The effects of the Gold Rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, called "forty-niners" (referring to 1849, the peak year for Gold Rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii) and Latin America in late 1848. Of the approximately 300,000 people who came to California during the Gold Rush, about half arrived by sea and half came overland on the California Trail and the Gila River trail; forty-niners often faced substantial hardships on the trip. While most of the newly arrived were Americans, the gold rush attracted thousands from Latin America, Europe, Australia and China. Agriculture and ranching expanded throughout the state to meet the needs of the settlers. San Francisco grew from a small settlement of about 200 residents in 1846 to a boomtown of about 36,000 by 1852. Roads, churches, schools and other towns were built throughout California. In 1849 a state constitution was written. The new constitution was adopted by referendum vote; the future state's interim first governor and legislature were chosen. In September 1850, California became a state. At the beginning of the Gold Rush, there was no law regarding property rights in the goldfields and a system of "staking claims" was developed. Prospectors retrieved the gold from streams and riverbeds using simple techniques, such as panning. Although mining caused environmental harm, more sophisticated methods of gold recovery were developed and later adopted around the world. New methods of transportation developed as steamships came into regular service. By 1869, railroads were built from California to the eastern United States. At its peak, technological advances reached a point where significant financing was required, increasing the proportion of gold companies to individual miners. Gold worth tens of billions of today's US dollars was recovered, which led to great wealth for a few, though many who participated in the California gold rush earned little more than they had started with.
