As part of the wider anti-war movement of the 1960s, student organisations such as the Harvard chapter of the
Students for a Democratic Society (SDS) ran anti-war activities on campus. In November 1966 for instance, Secretary of Defense Robert McNamara was prevented from leaving the campus by a group of about 800 students. Forced from his car, he was hoisted up on the hood of a convertible, where he agreed to answer questions from the crowd on the Vietnam War. A letter signed by 2,700 Harvard undergraduates apologising to McNamara was sent to him a few days after. A year later, in October 1967, a recruitment visit by
Dow Chemicals, which supplied napalm to the military, was interrupted by protests. The Harvard
Reserve Officer Training Corps (ROTC) programs drew particular attention, with sit-ins disrupting their meetings. Although the faculty was willing to reduce the programs’ privileges, the
Harvard Corporation refused to terminate it. These developments, alongside the creation of a degree program in Afro-American studies, led to the events of April 1969. == 1969: Occupation of University Hall ==
