On August 11, 1965, the arrest of Black motorist Marquette Frye after a traffic stop sparked six days of unrest in Los Angeles’s Watts neighborhood. The rebellion left 34 people dead, caused extensive destruction, and drew national attention to police-community tensions, poverty, unemployment, and housing discrimination. It occurred amid the civil rights era, showing that recent federal reforms had not resolved the racial and economic inequalities confronting many Black residents of Northern and Western cities.
