On 31 March 1968, faced with widespread domestic protests, especially on university campuses, over his conduct of the Vietnam War, President Lyndon Johnson, announced on national television that he would not seek his party’s nomination for the presidency. The Democratic National Convention (DNC), which was held in Chicago, proved to be chaotic with the local police viciously attacking anti-war protestors outside the convention venue.
Within the venue itself the party split between the supporters of the antiwar candidate Senator Eugene McCarthy, and the pro-war candidate, Vice-President Hubert Humphrey.
