One cause of World War II was the rise of fascism and the aggressive expansionist policies of Adolf Hitler and the Nazi Party in Germany. Their goal was to create a German empire through the conquest of other countries, which led to the invasion of Poland and the subsequent outbreak of the war. Another cause of World War II was the failure of the Treaty of Versailles in the aftermath of World War I. The harsh reparations imposed on Germany, along with territorial losses and economic instability, created resentment and a desire for revenge, setting the stage for the rise of totalitarian regimes and ultimately, the start of the war.
