Operation Barbarossa

Operation Barbarossa (German: Unternehmen Barbarossa) was the code name for the Axis invasion of the Soviet Union, which started on Sunday, 22 June 1941, during World War II. The operation stemmed from Nazi Germany's ideological aims to conquer the western Soviet Union so that it could be repopulated by Germans (Lebensraum), to use Slavs as a slave labour force for the Axis war effort, and to murder the rest and to acquire the oil reserves of the Caucasus, and the agricultural resources of Soviet territories.
