History, Culture & Diversity

Sonoma County played a pivotal role in California’s history. It was here that the northern expansion of Spain met the southern expansion of Russia on the Pacific Coast and marked the limit of expansion for both countries. It was in Sonoma County that American settlers staged the famed Bear Flag revolt that led to California’s joining the United States, and it was here that the California wine industry was born. Our cities and smaller communities all boast memorials to this rich and varied history. Many larger communities have visitor centers that will help you find places of historical interest and most have walking or driving tours to help you better understand local history.

Additionally, a number of cultural associations connect you to music, museums, and performances within the County and the greater Bay Area. Please visit the rest of this section to learn more.
