Until the invasion of the Soviet Union on 22 June 1941 the hunt for communists was not a high priority on the Nazi agenda, because of the signing of the Nazi-Soviet Pact on 23 August 1939.
Prioritizing communists was not a main concern for the Nazis until they launched an attack on the Soviet Union on June 22, 1941, following the agreement between Nazi Germany and the Soviet Union on August 23, 1939.
