World War II officially started on September 1, 1939, when Germany, under Adolf Hitler, invaded Poland. This aggressive act prompted Britain and France to declare war on Germany, marking the beginning of one of the most significant global conflicts in history. While many remember December 7, 1941, as a critical moment when Japan bombed Pearl Harbor, that event occurred later in the war and resulted in the United States joining the conflict. The invasion of Poland, however, is recognized as the catalyst that ignited a full-scale war across Europe.
