The 1960s was a turbulent period in Bangladesh, when demands for East Pakistani autonomy became stronger. The students and staff of the university started playing an increasing role in politics. On 18 February 1969, Shamsuzzoha, a professor, was killed by the police when he tried to prevent them from shooting student demonstrators. This date is now commemorated as Zoha Day. During the Bangladesh Liberation War of 1971, the campus was used as a base by the Pakistan Army. A number of professors, students and officers of the university were killed by the Pakistan army during this period.
