Causes of World War II
World War II did not begin suddenly. It was the result of a combination of political, economic, and social factors that developed over decades. Understanding these causes helps explain why the conflict escalated so rapidly.
Main Causes
- Treaty of Versailles (1919): Imposed harsh penalties on Germany after World War I.
- Economic Crisis: The Great Depression led to instability and extremism.
- Rise of Totalitarian Regimes: Leaders like Hitler, Mussolini, and militarists in Japan gained power.
- Expansionism: Germany, Italy, and Japan sought to expand their territories.

| Cause | Description | Impact |
|---|---|---|
| Treaty of Versailles | Severe restrictions on Germany | Fuelled resentment |
| Economic Crisis | Global financial instability | Rise of extremist ideologies |
| Expansionism | Territorial ambitions | Increased conflicts |
Many people think WWII started only because of Hitler. In reality, it was a combination of long-term global tensions.
When studying causes, always connect economic, political, and social factors together—they rarely act independently.
