The Soviet and Belarusian historiographies study the subject of German occupation in the context of contemporary Belarus, regarded as the Byelorussian Soviet Socialist Republic, a constituent republic of the Soviet Union in the 1941 borders as a whole. Polish historiography insists on special, even separate treatment for the East Lands of the Poland in the 1921 borders, which were incorporated into the BSSR after the Soviet invaded Poland on September 17, 1939. More than 100,000 people of different ethnic backgrounds, mostly Poles and Jews in West Belarus were imprisoned, executed or transported to the eastern USSR by Soviet authorities before the German invasion. The NKVD killed more than 1,000 prisoners in June/July 1941, for example, in Chervyen, Hlybokaye and Vileyka. These crimes stoked anti-Communist feelings in the Belarusian population and were used by German anti-Semitic propaganda.
Invasion
After twenty months of Soviet rule in Western Belarus and Western Ukraine, Nazi Germany and its Axis allies invaded the Soviet Union on June 22, 1941. Eastern Belarus suffered particularly heavily during the fighting and German occupation. Following bloody encirclement battles, all of the present-day Belarus territory was occupied by the Germans by the end of August 1941. With Poland regarding the Soviet annexation as illegal, the majority of Polish citizens did not ask for Soviet citizenship from 1939 to 1941, and as a result were Polish citizens under Soviet and later German occupation.
Occupation
In the early days of the occupation, a powerful and increasingly well-coordinated Soviet partisan movement emerged. Hiding in the woods and swamps, the partisans inflicted heavy damage to German supply lines and communications, disrupting railway tracks, bridges, telegraph wires, attacking supply depots, fuel dumps and transports, and ambushing Axis soldiers. In one of the most successful partisan sabotage actions of the entire Second World War, the so-called Asipovichy diversion of July 30, 1943, four German trains with supplies and Tiger tanks were destroyed. To fight partisan activity, the Germans had to withdraw considerable forces behind their front line. On June 22, 1944, the huge Soviet Strategic Offensive Operation Bagration was launched, finally regaining all of Belarus by the end of August.
War crimes
Germany imposed a brutal regime, deporting some 380,000 people for slave labour, and killing hundreds of thousands of civilians more. The population was to be exterminated for German colonization. At least 5,295 Belarusian settlements were destroyed by the Nazis and some or all their inhabitants killed. More than 600 villages like Khatyn were annihilated with their entire population. Altogether, over 1 million were killed in Belarus during the three years of German occupation. A 2017 study found "that Soviet partisan attacks against German personnel provoked reprisals against civilians but that attacks against railroads had the opposite effect. Where partisans focused on disrupting German supply lines rather than killing Germans, occupying forces conducted fewer reprisals, burned fewer houses, and killed fewer people." , Minsk, June 1943. , Professor Radasłaŭ Astroŭski.

Later in 1944, 30 German-trained Belarusians were airdropped behind the Soviet front line to spark disarray. These were known as "Čorny Kot" led by Michał Vituška. They had some initial success due to disorganization in the rear guard of Red Army. Other Belarusian units slipped through Białowieża Forest and full scaleguerilla war erupted in 1945. But the NKVD infiltrated these units and neutralized them until 1957. In total, Belarus lost a quarter of its pre-war population in the Second World War, including practically all its intellectual elite. About 9,200 villages and 1,200,000 houses were destroyed. The major towns of Minsk and Vitebsk lost over 80% of their buildings and city infrastructure. For the defense against the Germans, and the tenacity during the German occupation, the capital Minsk was awarded the title Hero City after the war. The fortress of Brest was awarded the title Hero-Fortress.
