World War II began primarily due to the aggressive expansionist policies of Nazi Germany, led by Adolf Hitler, who sought to revise the post-World War I order and expand German territory. The invasion of Poland on September 1, 1939, prompted Britain and France to declare war on Germany. Additionally, unresolved issues from World War I, economic instability, and the rise of totalitarian regimes contributed to the outbreak of the conflict. The war ultimately involved numerous countries and complex alliances, escalating into a global conflict.
