Other contributing factors included unresolved issues from World War I, such as the Treaty of Versailles and the Great Depression.

4. **Outcome**: The war ended in 1945 with the unconditional surrender of Germany and Japan. The Allies emerged victorious, but the war had devastating consequences, resulting in millions of deaths and widespread destruction.
5. **Impact**: The Second World War led to significant geopolitical changes, including the rise of the United States and the Soviet Union as superpowers, the beginning of the Cold War, and the establishment of the United Nations to promote international cooperation and prevent future conflicts.
