The growth of the university came to a halt with [[World War I]]. Financial and economic problems in Germany in the aftermath of the war resulted in reduced government funding for the university. The University of Bonn responded by trying to find private and industrial sponsors. In 1930 the university adopted a new constitution. For the first time students were allowed to participate in the self-governing university administration. To that effect the [[Students' union|student council]] Astag (German: {{Lang|de|Allgemeine Studentische Arbeitsgemeinschaft}}) was founded the same year. Members of the student council were elected in a secret ballot.

After the Nazi takeover of power in 1933, the [[Gleichschaltung]] transformed the university into a Nazi educational institution. According to the [[Führerprinzip]] the autonomous and self-governing administration of the university was replaced by a hierarchy of leaders resembling the military, with the university president being subordinate to the ministry of education. Jewish professors and students and political opponents were ostracized and expelled from the university. The theologian [[Karl Barth]] was forced to resign and to emigrate to Switzerland for refusing to swear an oath to Hitler. The Jewish mathematician [[Felix Hausdorff]] was expelled from the university in 1935 and committed suicide after learning about his impending deportation to a concentration camp in 1942. The philosophers [[Paul Ludwig Landsberg]] and Johannes Maria Verweyen were deported and died in [[Nazi concentration camps|concentration camps]]. In 1937 [[Thomas Mann]] was deprived of his honorary doctorate. His honorary degree was restored in 1946.

During the [[World War II|second World War]] the university suffered heavy damage. An [[Strategic bombing during World War II|air raid]] on 18 October 1944 destroyed the main building.{{Citation needed|date=July 2017}}
