Context

Background

The 1968 Columbia University protests grew from two specific grievances: Columbia's membership in the Institute for Defense Analyses, a Pentagon-linked research consortium conducting classified Vietnam War studies, and the university's plan to build a gymnasium in Morningside Park, a facility that critics called 'Gym Crow' because it would have a separate, inferior entrance for Harlem residents. The occupation began on April 23, 1968, when SDS members and members of the Student Afro-American Society rallied at the Sundial on campus before seizing Hamilton Hall. Within hours, the SDS and SAS agreed to separate: Black students remained in Hamilton Hall, which they renamed Malcolm X Liberation College and decorated with portraits of Black Power leaders, while white SDS students moved to Low Library and later additional buildings. By the end of April 25, five buildings were occupied by hundreds of students. An Ad Hoc Faculty Group of more than 200 professors formed a human cordon to try to prevent police from entering. President Grayson Kirk refused to negotiate and ultimately called in the police. The sweep on April 30 was brutal: while Hamilton Hall's 86 occupants surrendered peacefully, police dragged students from other buildings and beat spectators on surrounding streets. In all, more than 700 people were arrested and 148 were injured. The upheaval accelerated Kirk's resignation and contributed to lasting changes in university governance, research transparency policies, and community relations at Columbia and across American higher education.
Analysis

Key Findings

Five Columbia University buildings were occupied for a week beginning April 23, 1968, in one of the most significant student uprisings in American higher education history
No electronic mass notification system existed at Columbia in 1968; all communication relied on posted notices, faculty announcements, and word of mouth
The Black and white student contingents voluntarily separated early in the occupation: Black students held Hamilton Hall as Malcolm X Liberation College while white students occupied Low Library and three other buildings
The April 30 police sweep resulted in 712 arrests and 148 injuries; Columbia president Grayson Kirk subsequently resigned
Outcome
Columbia suspended construction of the Morningside Park gymnasium. The university severed ties with the Institute for Defense Analyses. More than 700 students and bystanders were arrested during the April 30 police sweep. The upheaval led to the resignation of university president Grayson Kirk.
