Los Angeles—often simply called L.A.—is the largest city in the
state of California and the second-largest in the United States in
terms of population. It is an alpha world city having a population
of about 4 million people and spanning 469.1 square miles (1214.9
square kilometers). The Los Angeles–Long Beach–Santa Ana
metropolitan area is home to 12.9 million people. The Los Angeles
Area encompasses a much larger area though, consisting of 5
counties, known as the Greater Los Angeles Area, or just the LA
Area.
Los Angeles was founded in 1781 by Spanish Captain Rivera y Moncada.
It was a part of Mexico, since it gained independence from Spain in
1821, until 1848, when Mexico ceded California to the United States
by treaty at the conclusion of the Mexican-American War. It was not
incorporated as a municipality until April 4, 1850—five months
before California achieved statehood. It is the county seat of Los
Angeles County.
Los Angeles is one of the world's centers of culture, science,
technology, international trade, and higher education, and is home
to world-renowned institutions in a broad range of professional and
cultural fields. The city and its immediate surrounding vicinity
lead the world in producing popular entertainment—such as motion
picture, television, and recorded music—which forms the base of Los
Angeles's international fame and global status.
