World War II (1939-1945) was the deadliest conflict in history, pitting the Axis powers against the Allies, and reshaping global politics and society.
Causes / Foundations
- Harsh Treaty of Versailles terms fuelled German resentment and economic hardship.
- Rise of fascism and totalitarian leaders: Hitler in Germany, Mussolini in Italy.
- Failure of appeasement policies allowed aggressive expansion, e.g. Germany's invasion of Poland.
Key Events & Dates
- 1 September 1939: Germany invades Poland, starting the war in Europe.
- 7 December 1941: Japan attacks Pearl Harbor, bringing the US into the war.

- 6 June 1944: D-Day landings in Normandy begin liberation of Western Europe.
- August 1945: Atomic bombs dropped on Hiroshima and Nagasaki; Japan surrenders.
Key Figures
- Adolf Hitler: Nazi Germany's dictator responsible for the Holocaust and war.
- Winston Churchill: British Prime Minister who led resistance against Germany.

Consequences
