The 1943 University of Oslo fire (Norwegian: aula-brannen) was a fire in the ceremony hall (Universitetets Aula) of the University of Oslo in 1943. Its direct consequences were the closing of the university, and the arrest of 1,166 people; these were chiefly male students. Of these, 644 were sent to German "readjustment" camps, where 17 people died. Initial beliefs that the fire was either a Reichstag fire or perpetrated by communists were wrong; members of the Norwegian resistance movement were responsible.
