The civil rights movement and general upheaval in the mid-1960s created the conditions for race riots in major cities. In 1965, Watts was riven by violence which saw over thirty deaths. Two years later, in 1967, both Detroit and Newark exploded with racial tension. After the assassination of the Reverend Martin Luther King, a new wave of racially-motivated riots struck over 100 U.S. cities.
