Columbia Students Seize Campus: Vietnam Protest Shuts University

Students at Columbia University occupied five campus buildings on April 23, 1968, protesting the university's involvement in defense research through the Institute for Defense Analyses and its plan to build a gymnasium in Morningside Park that would have restricted access for the neighboring Harlem community. The occupation lasted a week before NYPD officers cleared the buildings on April 30, arresting 712 people and injuring over 100. The violent police response radicalized moderate students and faculty, shutting down the university for the remainder of the semester. Columbia dropped both the gym project and its IDA affiliation. The protests inspired similar occupations at dozens of universities across the country and reshaped the relationship between universities and their surrounding communities.
