Overview
When the Second World War in Europe began, the territory which now forms the country of Belarus was divided between the Soviet Union (specifically the Byelorussian Soviet Socialist Republic) and the Second Polish Republic. The borders of Soviet Belarus were greatly expanded in the Soviet invasion of Poland of 1939. In 1941, the country was occupied by Nazi Germany. Following the German military disasters at Stalingrad and Kursk, the collaborationist Belarusian Central Council (BCC) was formed by the Germans in order to raise local support for their anti-Soviet operations. The BCC in turn formed the twenty-thousand strong Belarusian Home Defence (BKA), active from 23 February 1944 to 28 April 1945. Assistance was offered by the local Soviet administrative governments, and prewar public organizations including the former Soviet Belarusian Youth. The country was soon retaken by the Red Army in 1944. Devastated by the war, Belarus lost significant populations and economic resources. Many battles occurred in Belarusian and neighbouring territory. Belarusians also participated in regional conflicts.
September 1939 – June 1941
The Molotov–Ribbentrop Non-Aggression Pact of August 1939 had established a non-aggression agreement between Nazi Germany and the Soviet Union, and a secret protocol described how Finland, Estonia, Latvia, Lithuania, Poland (Second Polish Republic) and Romania would be divided between them.
In the Invasion of Poland of 1939 the two powers invaded and partitioned Poland, and to return the Ukrainian, Belarusian, and Moldavian territories in the North and North-Eastern regions of Romania (Northern Bucovina and Bessarabia).
