The1968 Chicago riots were sparked in part by the assassination of Martin Luther King Jr. Rioting and looting followed, with people flooding out onto the streets of major cities, primarily in black urban areas.
In Chicago itself, more than 48 hours of rioting left 11 Chicago citizens dead, 48 wounded by police gunfire, 90 policemen injured, and 2,150 people arrested.
A few months later, the 1968 Democratic National Convention protests were a series of protests against the United States’ involvement in the Vietnam War that took place prior to and during the 1968 Democratic National Convention in Chicago, Illinois. The protests lasted approximately seven days, from August 23 to August 29, 1968. – WIKIPEDIA
