The Soviet Invasion of Poland, 1939 / Sowiecka inwazja na Polskę, 1939

The Soviet invasion of Poland was a military operation by the Soviet Union without a formal declaration of war. On 17 September 1939, the Soviet Union invaded Poland from the east, sixteen days after Germany invaded Poland from the west. Subsequent military operations lasted for the following 20 days and ended on 6 October 1939 with the two-way division and annexation of the entire territory of the Second Polish Republic by Germany and the Soviet Union. The joint German-Soviet invasion of Poland was secretly agreed to following the signing of the Molotov–Ribbentrop Pact on 23 August 1939.
