History

Los Angeles County is one of the original counties of California, created at the time of statehood in 1850.[11] The county originally included parts of what are now Kern, San Bernardino, Riverside and Orange counties. In 1851 and 1852, Los Angeles County strechted from the coast to the border of Nevada.[12] As the population increased, sections were split off to organize San Bernardino County in 1853, Kern County in 1866, and Orange County in 1889.
