Adolf Hitler. World War II

Germany launched successful Blitzkrieg campaigns against Poland, Denmark, Norway, Belgium, the Netherlands, and France.

Germany launched a massive invasion of the Soviet Union, which proved to be a costly and ultimately unsuccessful campaign.

The Battle of Stalingrad marked a significant turning point in the war on the Eastern Front, with Germany suffering heavy losses.

Allied forces advanced on multiple fronts, leading to the eventual defeat of Germany and Hitler's suicide in April 1945.
