How Nazi Germany and the Soviet Union systematically dismantled a nation during World War II.
Following the 1939 invasion, Poland was carved up by two hostile powers intent on erasing its sovereignty and culture. Through forced labor, mass deportations, and the systematic extermination of its intellectual and religious elites, the occupation sought to transform the nation into a territory of German living space.
The occupation of Poland, beginning in September 1939, was a coordinated effort by Nazi Germany and the Soviet Union to subjugate the Polish people. Under the Molotov–Ribbentrop Pact, the territory was divided, with Germany annexing western regions and the Soviet Union seizing over 51% of the land. Both powers aimed to eradicate Polish culture, with Germany specifically implementing the genocidal Generalplan Ost. This plan envisioned the eventual elimination of Slavs and Jews from Central and Eastern Europe, replacing them with millions of German settlers over several decades.
The German administration, led by Governor-General Hans Frank, initiated a campaign of terror targeting the Polish intelligentsia, clergy, and leadership. Operations like the AB-Aktion and Operation Tannenberg saw tens of thousands of professionals and community leaders arrested, imprisoned, or executed to prevent organized resistance. Simultaneously, the Nazis implemented a rigid racial hierarchy, classifying citizens through the Deutsche Volksliste. Those deemed suitable for Germanization were forced to assimilate, while others were relegated to slave labor or sent to extermination camps like Auschwitz, Treblinka, and Majdanek.
The human cost was catastrophic. Between 1939 and 1945, approximately six million Polish citizens died, representing nearly 21.4% of the pre-war population. Over 90% of these deaths were non-military, resulting from deliberate actions, including mass executions, purposeful starvation, and the systematic murder of three million Polish Jews. By the end of the war, the Soviet Union occupied all of Poland, leading to a significant westward shift of the nation's borders, while the legacy of the occupation remained defined by the International Military Tribunal at Nuremberg as a deliberate and systematic genocide.
