The name Napa may come from Napato, a clan of the Wintun Indians who once lived along a river that flows into San Francisco Bay. In the 1850s, miners sought refuge in the young city that grew up by the Napa River, living in tents along its main street. Later they and other newcomers found work at businesses and nearby ranches while Napa City flourished as goods and produce from all over the valley were loaded onto steamers bound for San Francisco. Shortening its name in 1900, Napa continued to provide housing and shops, utilities and transportation for a growing agricultural center, and it shared the valley's economic hard times through Prohibition and the Great Depression.
