The invasion of Poland (September campaign, Polish: Kampania wrześniowa; 1939 defensive war, Polish: Wojna obronna 1939 roku; Poland campaign, German: Überfall auf Polen) 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 between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact.[13] The Soviets invaded Poland on 17 September. 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.
