After 1933, it was, like all German universities, transformed into a Nazi educational institution. Some 20,000 books by "degenerates" and opponents of the regime were taken from the university library and burned. Jewish students and scholars and political opponents of Nazis were ejected from the university and often deported. After World War II, the University was reopened by the Soviet Union, and was heavily influenced by the communist model, a state of affairs that continued until the end of the Cold War. In 1949, it was renamed Humboldt University of Berlin.
