Los Angeles is a city with a rich and fascinating history. From its earliest days as the home of the Chumash and Tongva indigenous peoples, to its current status as a major metropolitan area, Los Angeles has seen many changes over the centuries. The official name of the city, City of Los Angeles, has been in use since at least 1850 when it became an American city. The origin of the name “Los Angeles” is Spanish, and it is believed to have been derived from the original native village of Yaangva.
This village flourished on the banks of the Los Angeles River and provided resources such as fish, nutrient-rich land and fresh water before it emptied into the Pacific Ocean. The city is known for its Mediterranean climate, its ethnic and cultural diversity, the Hollywood film industry and its extensive metropolitan area. There are numerous additional colleges and universities outside city limits in the Los Angeles metropolitan area, including the Claremont Colleges consortium, which includes some of the most selective liberal arts colleges in the United States. Los Angeles has a diverse economy and is home to companies in a wide range of professional and cultural fields.
It is also home to many celebrities and other artists who live in various districts throughout the city. During World War II, Los Angeles was an important wartime manufacturing center, such as shipbuilding and aeronautics. The city's main train station is Union Station, just north of the city center. In addition, the city contracts directly for local and commuter bus service through the Los Angeles Department of Transportation (LADOT).
Air quality problems in Los Angeles and other major cities led to the passage of early national environmental legislation, including the Clean Air Act. The charter of the City of Los Angeles, ratified by voters in 1999, created a system of advisory neighborhood councils that would represent the diversity of stakeholders, defined as people who live, work or own property in the neighborhood. Neighborhood councils are relatively autonomous and spontaneous, as they identify their own boundaries, establish their own statutes and elect their own officials.Also called Port of Los Angeles and WORLDPORT LA, the port complex occupies 30 km of land and water along 43 miles (69 km) of coastline. On September 14, 1908, the Los Angeles City Council enacted residential and industrial land use zones.
This applies to both residential and professional buildings in and around the city.Latino street gangs such as Los Sureños, a Mexican-American street gang, and Mara Salvatrucha, which mainly has members of Salvadoran descent, originated in Los Angeles. Many of these native species such as the Los Angeles sunflower have become so rare that they are considered endangered.
