The county was formed on March 25, 1853 from a large portion of Contra Costa County and a smaller portion of Santa Clara County.
The word 'alameda' means 'a place where poplar trees grow', a name which originally was given to the Arroyo de la Alameda (Poplar Grove Creek). The willow and sycamore trees along the banks of the river reminded the early explorers of a road lined with trees, also known as an 'alameda'.
The county seat at the time it was formed was located at Alvarado; it was moved to San Leandro in 1856 where the county courthouse was destroyed by the devastating 1868 quake on the Hayward Fault. The county seat was then re-established in the town of Brooklyn from 1872-1875. Brooklyn is now part of Oakland, which has been the county seat since 1873.
Much of what is now considered an intensively urban region, with major cities, was developed as a trolley car suburb of San Francisco in the late 19th and early 20th centuries. The historical progression from native American tribal lands to Spanish, then Mexican ranches, thence to farms, ranches, and orchards, suburbs and eventually cities, is shared with the adjacent Contra Costa County (see that article for an extensive history applicable to this county).
Alameda County is governed by an elected Board of Supervisors.
The county's law enforcement is overseen by an elected county sheriff supervising a force of deputies whose primary responsibilities include policing unincorporated areas of the county, and providing security for county buildings including courthouses, the county jail and other properties. The County Sheriff also serves various court writs and warrants.
The annual Alameda County fair is held at the fairgrounds in Pleasanton. The fair runs for 3 weekends from June to July. Attractions include horse racing, carnival, 4-H exhibits, and live bands.
According to the U.S. Census Bureau, the county has a total area of 2,127 km² (821 sq mi). 1,910 km² (738 sq mi) of it is land and 216 km² (84 sq mi) of it (10.18%) is water.
The San Francisco Bay borders the county on the west. The crest of the Berkeley Hills form part of the northeastern boundary, and reach into the center of the county. A coastal plain several miles wide lines the bay, being home to Oakland and the most populated regions. Livermore Valley lies in the eastern part of the county.
The Hayward Fault, a major branch of the San Andreas Fault to the west, runs through the most populated parts of Alameda County, while the Calaveras Fault runs through the southeastern part of the county.

Alameda County is a stronghold of the Democratic Party. It has not voted Republican since Dwight Eisenhower in 1956. Even when Ronald Reagan won the national popular vote by an 18.3% margin in 1984, Walter Mondale won Alameda County by a slightly larger margin. In 2004 it voted for John Kerry by a margin of over 50%. Every city and town voted Democratic. [1] In the House of Representatives, all of the 9th district, parts of the 10th and 11th districts, and most of the 13th district are in the county. All four districts are held by Democrats: Barbara Lee, Ellen Tauscher, Jerry McNerney, and Pete Stark, respectively.
In the State Assembly, parts of the 14th and 15th districts, all of the 16th and 18th districts, and most of the 20th district are in the county. Four of its five legislators are Democrats: Loni Hancock of the 14th district, Sandré Swanson of the 16th district, Mary Hayashi of the 18th district, and Alberto Torrico of the 20th district. The lone Republican that represents Alameda County is Guy Houston of the 15th district. In the State Senate, most of the 9th and 10th districts are in the county and are both represented by Democrats: Don Perata and Ellen Corbett, respectively.
According to the Alameda County registrar for 2008, 370,919 (55.2%) are registered Democrats, 117,086 (17.4%) are registered Republicans, 36,276 (5.4%) are registered to minor political parties, and 147,279 (21.9%) declined to answer. This means the Democrats have a 37.8% registration advantage over the Republicans. Every city and town in Alameda County has more registered Democrats than Republicans, except for Livermore and Pleasanton, and Republicans hold registration advantages in those cities by razor-thin margins.
