Overview of alameda county

Alameda County was established on March 25, 1853, from a significant portion of Contra Costa County and a smaller part of Santa Clara County. At its creation, Alvarado, now part of Union City, served as the county seat. However, the 1868 Hayward Fault earthquake destroyed the county courthouse, and the county seat was relocated to San Leandro. From 1872 to 1875, the county seat was established in Brooklyn, which is currently part of Oakland. Oakland has been the county seat since 1873. During the late 19th and early 20th centuries, much of the region, which is now an intensely urban area, was developed as a trolley car suburb of San Francisco. The area’s historical evolution from Native American tribal lands to Spanish and then Mexican ranches, farms, orchards, and multiple city centers and suburbs is similar to the closely associated Contra Costa County.
