Causes of World War II: Economic Collapse and Hitler's Rise

1. The Background: The Great Depression

1929 Wall Street Crash and the Great Depression

The economic collapse triggered several critical consequences:

• Short-term impacts: A sharp drop in industrial production and dramatic spikes in unemployment.
• Economic pressure: Governments struggled to balance budgets, leading to reduced defense spending and an urgent need to secure new markets and raw materials.
• Diplomatic hesitation: Nations became increasingly reluctant to impose economic sanctions.

Impacts on Politics and International Relations

• Rise of Extremism: Extremist parties gained power, fostering militarism.
• Nationalism: Countries prioritized self-interest, leading to increased hostility and impatience toward neighbors.
• Expansionism: Dissatisfied nations adopted the "safety valve theory," becoming ready to invade others to resolve internal pressures.
• Weakness of the League of Nations: The organization proved ineffective, reacting too slowly or failing to act entirely.

Key Failures of Collective Security

• 1931–32: Japanese invasion of Manchuria. Lesson: Aggressors succeed if they act quickly and decisively.
• 1932–34: Disarmament Conference. Lesson: Aggressors can rearm without effective opposition.
• 1935–36: Italian invasion of Abyssinia. Lesson: Strong aggressors can act with impunity.

Dissatisfied Powers and the Peace Treaties

• Italy: Denied Fiume, the Dalmatian coast, and former German colonies.
• Japan: Rejected "racial equality" clauses and denied former German trading rights in China.
• Germany: Resented the Treaty of Versailles, specifically disarmament, reparations, territorial losses, and the "War Guilt" clause.

2. Hitler's Foreign Policy: Justifiable Claims?

Aims: "Make Germany Great Again"

• Destroy Versailles: Rearm the nation, introduce conscription, rebuild the navy and air force, and remilitarize the Rhineland.
• Territorial Expansion:
  • Annex the Sudetenland (Czechoslovakia) for its raw materials, manufacturing, and military defenses.
  • Occupy Prague and Memel.
  • Assert claims over Danzig and the Polish Corridor.
  • Achieve Anschluss (union with Austria).
• Grossdeutschland: Create a Reich encompassing all German-speaking nations.
• Anti-Communism: Plan for the invasion of the USSR.
• Lebensraum: Conquer Eastern Europe (Poland and the USSR) to provide living space.
• Central-European Hegemony: Establish Germany as the dominant empire in Europe.

Inconsistencies with the Treaty of Versailles

• The Polish Corridor separated East Prussia from the rest of Germany.
• Danzig, a predominantly German city, was placed under international control.
• Approximately 3.5 million Germans remained within the borders of Czechoslovakia.

Historical Perspectives

Historians debate whether Hitler followed a calculated program of colonization and conquest (Stufenplan) or if he was a tactical opportunist who achieved gains through audacity and direct action.
