The Soviet Union invaded Poland on September 17, 1939, not 1938, as part of a secret pact with Nazi Germany. This action, following Germany's September 1 attack, resulted in the division of Poland and initiated a brutal two-year occupation, marking the "fourth partition" of the country.
Key Facts About the 1939 Invasion:
Context: The invasion was a direct result of the Molotov-Ribbentrop Pact (August 23, 1939), a non-aggression treaty between Nazi Germany and the Soviet Union that divided Eastern Europe into spheres of influence.
The Attack: On September 17, 1939, the Red Army invaded eastern Poland without a formal declaration of war, claiming they were protecting Ukrainians and Byelorussians.
Outcome: Poland was divided between Germany and the USSR, with the Soviet Union occupying over 52% of Polish territory.
Repression: The invasion led to the imprisonment of over 250,000 Polish soldiers and the deportation of approximately 1.5 million Polish civilians, mostly to Siberia and Kazakhstan.
Atrocities: The occupation included the 1940 Katyn massacre, where the Soviet secret police (NKVD) executed over 20,000 Polish officers, scholars, and officials.

Loss of Freedom: Poland did not regain true independence after WWII, remaining under strict Soviet influence until the collapse of communism in 1989.
