In the 1940s, the Communist Party of Germany, with support from the Soviet Union, tried to work underground to build an "operative leadership". It was particularly active in 1943 and 1944 and was one of the largest groups in the German resistance against the National Socialist state. Its hub was in Berlin. Many of its members were arrested by the Gestapo in 1944 and later killed.
