In April 1968, students at Columbia University in New York City staged a protest against the university's involvement in the Vietnam War and its plans to build a gymnasium in Morningside Park. The protest escalated into a five-day occupation of several university buildings, during which students clashed with police and administrators. The university eventually agreed to many of the students' demands, including the withdrawal of its investments from companies that did business with the military and the cancellation of the gymnasium project.
