Los Angeles officially the City of Los Angeles and often known colloquially by its initials L.A., is the most populous city in California and the second most populous city in the United States, after New York. With an estimated population of four million, Los Angeles is the cultural, financial, and commercial center of Southern California. Nicknamed the "City of Angels" partly because of its name's Spanish meaning, Los Angeles is known for its Mediterranean climate, ethnic diversity, Hollywood, and the entertainment industry, and sprawling metropolis.

Los Angeles is in a large basin bounded by the Pacific Ocean on one side and by mountains as high as 10,000 feet (3,000 m) on the others. The city proper, which covers about 469 square miles (1,210 km2), is the seat of Los Angeles County, the most populated county in the country. Los Angeles is also the principal city of the Los Angeles metropolitan area, the second largest in the United States after that of New York City, with a population of 13.1 million. It is part of the Los Angeles-Long Beach combined statistical area, also the nation's second most populous area with a 2015 estimated population of 18.7 million.

Los Angeles is one of the most substantial economic engines within the United States, with a diverse economy in a broad range of professional and cultural fields. Los Angeles is also famous as the home of Hollywood, a major center of the world entertainment industry. A global city, it has been ranked 6th in the Global Cities Index and 9th in the Global Economic Power Index. The Los Angeles combined statistical area also has a gross metropolitan productof $831 billion (as of 2008), making it the third-largest in the world, after the Tokyo and New York metropolitan areas. Los Angeles hosted the 1932 and 1984 Summer Olympics and will host the event for a third time in 2028. The city also hosted the Miss Universe pageant twice, in 1990 and 2006, and was one of 9 American cities to host the 1994 FIFA men's soccer World Cup and one of 8 to host the 1999 FIFA women's soccer World Cup, hosting the finalmatch for both tournaments.

Historically home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California. The city was officially founded on September 4, 1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence. In 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, becoming part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood. The discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California, later assured the city's continued rapid growth.

Ensenada is a coastal city in Mexico, the third-largest in Baja California. Lying 125 kilometres (78 mi) south of San Diego on the Baja California Peninsula, it is locally referred to as La Cenicienta del Pacífico, "The Cinderella of the Pacific."

One of the first settlements founded in the Californias, Ensenada has emerged as a cruise ship destination, aerospace center, and a jumping-off point for Valle de Guadalupe, a local wine region. It is said that the first Vitis vinifera made it to the region's San Ignacio Mission in 1703, when Jesuit Padre Juan de Ugarte planted the first vineyards there.

Situated on the coastline of Bahía de Todos Santos—an inlet of the Pacific Ocean on the peninsula's Gold Coast—the Port of Ensenada is an important commercial, fishing, and tourist port. The city is home to a navy base, army base, and Ensenada Airport, a military airfield which doubles as an airport of entry into Mexico.

Ensenada is the municipal seat and cultural and commercial center of Ensenada Municipality, one of five into which the state is divided. As of 2015, the municipality had a population of 519,813.

Ensenada is backed by small mountain ranges. Proximity to the Pacific and a warm Mediterranean latitude create mild year-round weather. The rainy season during the winter is short and the area is prone to prolonged droughts, which can threaten its grape harvests. The National Park Constitution of 1857 created the Sierra de Juarez and San Pedro Martir National Parks, which maintain one of the best astronomical observatories in the country.

Ensenada is part of UNESCO´s Creative Cities Network since 2015.
