8.5 Interwar Instability

Economic Crisis and Political Fallout

The Great Depression (1929) devastated European economies already weakened by WWI debts and reparations. Mass unemployment and bank failures discredited liberal democracy, pushing voters toward extremist parties promising quick solutions. Governments struggled with deflationary policies, and social unrest grew as traditional political systems seemed unable to cope with the crisis.

Rise of Totalitarianism

Totalitarian regimes emerged as responses to instability: Mussolini's Fascism in Italy (1922), Stalin's Soviet Union with collectivization and purges, and Hitler's Nazi Germany (1933) exploiting resentment over the Treaty of Versailles. These regimes used propaganda, single-party rule, secret police, and charismatic leadership to control society and suppress dissent, rejecting parliamentary democracy entirely.

Failure of Collective Security

The League of Nations proved powerless to stop aggression, failing to act against Japan's invasion of Manchuria (1931) or Italy's invasion of Ethiopia (1935). Britain and France pursued appeasement, culminating in the 1938 Munich Agreement allowing Hitler to annex the Sudetenland, emboldening further aggression and paving the way toward World War II.
