*World War II: 1939–1945*
World War II was the deadliest conflict in human history. Over 30 countries took part,
fighting across six continents, and the war changed politics, society, and technology for
generations.
*1. Causes of the War*
Several factors led to the outbreak in September 1939:
- *Treaty of Versailles, 1919*: The severe terms imposed on Germany after World War I
caused economic hardship and resentment.
- *Rise of totalitarianism*: Aggressive leaders in Germany, Italy, and Japan pursued
territorial expansion.
- *Policy of appeasement*: Some European powers tried to avoid another war by making
concessions, which encouraged further aggression.
- *Invasions and alliances*: Germany’s invasion of Poland on 1 September 1939 led to
declarations of war. The conflict soon split into two blocs: the Axis Powers and the Allied
Powers.
*2. Major Phases of the War*
*Axis Advances, 1939–1941*
