Subdivisions

The U.S. state of California is divided into 58 counties. [1] The state was first divided into 27 counties on February 18, 1850. These were further sub-divided to form sixteen additional counties by 1860. Another fourteen counties were formed through further subdivision from 1861 to 1893. The most recent county to form was Imperial County, in 1907.

California is home to San Bernardino County, the largest county in the contiguous United States, as well as Los Angeles County, the most populous county in the United States.

California counties are general law counties by default, but may be chartered as provided in Article XI, Section 3 of the California Constitution. [2] A charter county is granted limited home rule powers. Of the 58 counties in California, 14 are governed under a charter. They are Alameda, Butte, El Dorado, Fresno, Los Angeles, Orange, Placer, Sacramento, San Bernardino, San Diego, San Francisco, San Mateo, Santa Clara, and Tehama. [3]

Nine counties in California are named for saints, tied with Louisiana for the largest number. This count omits Santa Cruz ("Holy Cross") County (not named for a saint), Merced County and Los Angeles County, both of whose names refer to Saint Mary, (i.e. Our Lady of Mercy (Merced) and Our Lady Queen of The Angels (Los Angeles)), and Ventura County, whose name is a shortening of the name of St. Bonaventure, the namesake of the local mission.
