The White Rose was a non-violent, intellectual resistance group in Nazi Germany which was led by five students and one LMU Munich professor: Willi Graf, Kurt Huber, Christoph Probst, Alexander Schmorell, and Hans and Sophie Scholl. The group conducted an anonymous leaflet and graffiti campaign that called for active opposition to the Nazi regime, beginning in Munich on 27 June 1942. Their activities ended with the arrest of the core group by the Gestapo on 18 February 1943.
