In Los Angeles, California, white U.S. Navy sailors and Marines clash with Latino youths in the Zoot Suit Riots.

The Zoot Suit Riots were a series of riots on June 38, 1943 in Los Angeles, California, United States, involving American servicemen stationed in Southern California and young Latino and Mexican American city residents. It was one of the dozen wartime industrial cities that suffered race-related riots in the summer of 1943, along with Mobile, Alabama; Beaumont, Texas; Detroit, Michigan; and New York City.

American servicemen and white Angelenos attacked and stripped children, teenagers, and youths who wore zoot suits, ostensibly because they considered the outfits, which were made from large amounts of fabric, to be unpatriotic during World War II. Rationing of fabrics and certain foods was required at the time for the war effort. While most of the violence was directed toward Mexican American youth; African American and Filipino American youths who were wearing zoot suits were also attacked.The Zoot Suit Riots were related to fears and hostilities aroused by the coverage of the Sleepy Lagoon murder trial, following the killing of a young Latino man in what was then an unincorporated commercial area near Los Angeles. The riot appeared to trigger similar attacks that year against Latinos in Chicago, San Diego, Oakland, Evansville, Philadelphia, and New York City. The defiance of zoot suiters became inspirational for Chicanos during the Chicano Movement.

Los Angeles (US: (listen) lawss AN-jəl-əs; Spanish: Los Ángeles [los ˈaŋxeles], lit. 'The Angels'), often referred to by its initials L.A., is the largest city in California. With a 2020 population of 3,898,747, it is the second-largest city in the United States, following New York City. Los Angeles is known for its Mediterranean climate, ethnic and cultural diversity, Hollywood film industry and sprawling metropolitan area.

The City of Los Angeles lies in a basin in Southern California, adjacent to the Pacific Ocean, and extends through the Santa Monica Mountains and into the San Fernando Valley, covering a total of about 469 square miles (1,210 km2). It is the seat of Los Angeles County, which is the most populous county in the United States with just over 10 million residents in 2020.

Home to the Chumash and Tongva indigenous peoples, the area that became Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542. The city was founded on September 4, 1781, under Spanish governor Felipe de Neve, on the village of Yaanga. 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, and thus became 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 city was further expanded with the completion of the Los Angeles Aqueduct in 1913, which delivers water from Eastern California.

Los Angeles has a diverse and robust economy, and hosts businesses in a broad range of professional and cultural fields. It also has the busiest container port in the Americas. In 2018, the Los Angeles metropolitan area had a gross metropolitan product of over $1.0 trillion, making it the city with the third-largest GDP in the world, after Tokyo and New York City. Los Angeles hosted the 1932 and 1984 Summer Olympics and will host the 2028 Summer Olympics. More recently, statewide droughts in California have further strained the city's water security.
