The Watts riots, sometimes referred to as the Watts Rebellion or Watts Uprising, took place in the Watts neighborhood and its surrounding areas of Los Angeles from August 11 to 16, 1965. On August 11, 1965, Marquette Frye, a 21-year-old African-American man, was pulled over for drunken driving. After he failed a field sobriety test, officers attempted to arrest him. Marquette resisted arrest, with assistance from his mother, Rena Frye; a physical confrontation ensued in which Marquette was struck in the face with a baton. Meanwhile, a crowd of onlookers had gathered. Rumors spread that the police had kicked a pregnant woman who was present at the scene. Six days of civil unrest followed, motivated in part by allegations of police abuse. Nearly 14,000 members of the California Army National Guard helped suppress the disturbance, which resulted in 34 deaths, as well as over $40 million in property damage. It was the city's worst unrest until the Rodney King riots of 1992. In the Great Migration of 1915–1940, major populations of African Americans moved to Northeastern and Midwestern cities such as Detroit, Chicago, St. Louis, Cincinnati, Philadelphia, Boston, and New York City to pursue jobs in newly established manufacturing industries; to cement better educational and social opportunities; and to flee racial segregation, Jim Crow laws, violence and racial bigotry in the Southern states. This wave of migration largely bypassed Los Angeles. In the 1940s, in the Second Great Migration, black workers and families migrated to the West Coast in large numbers, in response to defense industry recruitment efforts at the start of World War II. President Franklin D. Roosevelt issued Executive Order 8802 directing defense contractors not to discriminate in hiring or promotions, opening up new opportunities for minorities. The black population in Los Angeles dramatically rose from approximately 63,700 in 1940 to about 350,000 in 1965, rising from 4% of L.A.'s population to 14%.
