World War II had its roots in the aftermath of World War I and the punitive terms imposed on Germany by the Treaty of Versailles. The rise of totalitarian regimes, such as Nazi Germany under Adolf Hitler and Fascist Italy under Benito Mussolini, fueled tensions and set the stage for conflict.
The war began with the German invasion of Poland on September 1, 1939, triggering declarations of war from France and Britain. Major events included:
World War II resulted in millions of casualties and widespread destruction across Europe and parts of Asia and the Pacific. The war led to the establishment of the United Nations and the formation of the opposing superpowers of the United States and the Soviet Union, ushering in the Cold War era.
The Battle of Stalingrad, fought between July 1942 and February 1943, was a decisive turning point in the war. The Soviet defense of the city and the eventual encirclement and defeat of the German Sixth Army marked the first major defeat of Nazi Germany and is considered one of the bloodiest battles in human history.
