The first belligerent act of World War II is widely considered to be Germany's invasion of Poland on September 1, 1939. This military action followed the signing of the Molotov-Ribbentrop Pact between Germany and the Soviet Union, which included a secret protocol to divide Eastern Europe. The invasion prompted Britain and France to declare war on Germany on September 3, marking the official beginning of the conflict.
