The original date, set for May 1941, had to be revised to complete the vast preparations for the attack - following other German attacks on Yugoslavia and Greece in April. Not until December 1940, however, did Hitler make a final decision to go ahead with what became known as Operation Barbarossa. All of these factors contributed to the decision taken by Hitler in July 1940, after the German defeat of France, to plan for an all-out assault on the Soviet Union. His hatred of Soviet Communism and his crude ideas of economic imperialism, expressed in the pursuit of Lebensraum ('living-space'), made the Soviet Union a natural area for Hitler's warlike ambitions.Īfter the outbreak of war in 1939 came the added fear of Soviet expansion in Eastern Europe, while Germany was fighting the British Empire and France in the west. The roots of the war lie in the appointment of Adolf Hitler as German chancellor in 1933. The cost to the Soviet Union was an estimated 27 million dead.
It was here, in the vast struggle between the two dictatorships, that the German army was defeated and the outcome of World War Two was decided in favour of the Allied powers - the British Empire, the United States and the USSR.
