The Zoot Suit Riots were a series of violent clashes during which mobs of U.S. servicemen, off-duty police officers and civilians brawled with young Latinos and other minorities in Los Angeles. The June 1943 riots took their name from the baggy suits worn by many minority youths during that era, but the violence was more about racial tension than fashion.
