Los Angeles is the largest city in the State of California and the second largest city in the USA after New York.

The City of Los Angeles was founded on September 4, 1781, by Spanish governor Felipe de Neve as El Pueblo de Nuestra Señora la Reina de los Angeles del Río de Porciúncula (The Village of Our Lady, the Queen of the Angels of the river of Porziuncola). It became a part of Mexico in 1821, following its independence from Spain. 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, thereby becoming part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood.
