The discovery of gold at Sutter's Mill in Coloma on January 24, 1848, initiated one of the largest migrations in US history. Between 1849 and 1855, hundreds of thousands of migrants arrived in Northern California hoping to find gold in the foothills of the Sierra Nevada. The rapid population growth and economic prosperity led to boomtowns, banks, and railroads, making California eligible for statehood in 1850. An international cast of gold-seekers, merchants, and tradespeople arrived by land and through the port of San Francisco, which was transformed from a small village to a cosmopolitan metropolis. Jewish pioneers, many of whom had been merchants in Europe, opened stores and businesses in small towns and mining camps in and around the Mother Lode. They established benevolent societies and cemeteries, founded synagogues and companies, held public office and positions of influence, and contributed greatly to the multicultural fabric of the Gold Country.
