City (pop., 2000: 3,694,820), southern California, U.S. The second largest city in the U.S., it is situated between the San Gabriel Mountains and the Pacific Ocean.

It began in 1771 as a Spanish mission; the city was established as El Pueblo de la Reyna de los Angeles (the Town of the Queen of the Angels) in 1781. Taken by U.S. forces in the Mexican War , it prospered in the wake of the 1849 gold rush . Incorporated in 1850, the city grew rapidly after the arrival of the railroads in 1876 and 1885. In 1913 an aqueduct was built to supply it with water from the slopes of the Sierra Nevada . It was struck by a major earthquake in 1994. Sites of interest include early Spanish missions, the California at Los Angeles.
