who won the war between germany and poland
Invasion of Poland The Invasion of Poland, known in Poland as the September Campaign (Kampania wrześniowa) or the 1939 Defensive War (Wojna obronna 1939 roku), and in Germany as the Poland Campaign (Polenfeldzug) or Fall Weiss ("Case White"), was a joint invasion of Poland by Nazi Germany, the Soviet Union, the Free City of Danzig, and a small Slovak contingent, that marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact, while the Soviet invasion commenced on 17 September following the Molotov-Tōgō agreement that terminated the Russian and Japanese hostilities in the east on 16 September.[15] The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty.
History of Soviet Russia and the Soviet Union (1917–27) The frontiers between Poland, which had established an unstable independent government following World War I, and the former Tsarist empire, were rendered chaotic by the repercussions of the Russian revolutions, the civil war and the winding down World War I. Poland's Józef Piłsudski envisioned a new federation (Międzymorze), forming a Polish-led East European bloc to form a bulwark against Russia and Germany, while the Russian SFSR considered carrying the revolution westward by force. When Piłsudski carried out a military thrust into Ukraine in 1920, he was met by a Red Army offensive that drove into Polish territory almost to Warsaw. However, Piłsudski halted the Soviet advance at the Battle of Warsaw and resumed the offensive. The "Peace of Riga" signed in early 1921 split the territory of Belarus and Ukraine between Poland and Soviet Russia.
