History:

Alameda County is a Charter County. The charter and incorporation date is 25 March 1853. The county was formed from Contra Costa and Santa Clara Counties.

The name was chosen by early explorers for a creek they discovered that reminded them of a road lined with trees that is known as an alameda. They named the creek Arroyo de la Alameda or Poplar Grove Creek.

The first county seat was at Alvarado in 1853. Next, in 1856, it was moved to San Leandro. When an earthquake on the Hayward Fault in 1868 destroyed the courthouse and the area, the seat was moved to Brooklyn where it remained from 1872 to 1875. Brooklyn was absorbed by Oakland which was named the seat in 1873.
