Los Angeles County was one of the original 27 counties in the state. It was created 18 Feb 1850. The original size was only 4,340 square miles in a small area along the Pacific coast between Santa Barbara and San Diego. Less than a year later, the county was increased to a total of 34,520 square miles covering an area going east as far as the Colorado River. In 1889, Orange County was created from Los Angeles County, it being the last major detachment from Los Angeles County. Its present size is 4,083 square miles.

Some former cities are now consolidated into larger ones including:

Barnes City, Eagle Rock, Hollywood, Hyde Park, San Pedro, Sawtelle, Tujunga, Venice, Watts and Willmington all have been consolidated with the City of Los Angeles. Belmont Heights consolidated with Long Beach and Tropico consolidated with Glendale.

A History page for the county. Also try this history page.

The county flag was adopted on October 17, 1967. The county seal was adopted in 1957 and modified in 2004.

The Pobladores, a group of 46 people of 12 families, came to this area on September 4, 1781 to establish a home and community. They named it "El Pueblo de Nuestra Senora la Reina de Los Angeles de Porciuncula. Soon this was shortened to La Cuidad de Los Angeles or "The City of Angels". Now, of course, we know it as Los Angeles.
