Chapter 1
Causes of World War II (1933-1939)
Key Concepts
This chapter covers the political, economic, and ideological causes that led to World War II (1933-1939). For exams, you must link the collapse of the post-World War I settlement to the rise of aggressive dictatorships and the sequence of events from 1933 to the outbreak of war.
You MUST know:
• Breakdown of the post-WWI settlement: Versailles and the League of Nations weakened peace-building after Germany’s defeat (1919 onward).
• Political causes: states rejected the system-Germany under Hitler, Italy under Mussolini, and Japan under militarists.
• Economic causes: Great Depression (1929) increased unemployment, weakened democracies, and made radical parties more popular.
• Ideological causes: Nazi ideology (racial “master race,” anti-communism, anti-democracy) justified expansion; fascism promised national revival through dictatorship.
• Weakness of democracies: Britain and France often used appeasement, trading territory for “peace” instead of stopping aggression.
• Key timeline (1933-1939):
• 1933: Hitler becomes Chancellor in Germany
• 1933-35: Nazi rearmament; Germany withdraws from the League of Nations (1933)
• 1935: Germany reintroduces conscription
• 1935-36: Italy invades Ethiopia (shows weak collective response)
• 1936: Remilitarisation of the Rhineland
• 1938: Anschluss with Austria; Munich Agreement; Kristallnacht (Nov)
• 1939: German invasion of Poland (1 Sept) → Britain and France declare war (3 Sept)
Before you continue: Can you explain (in 3 linked points) how Versailles + the Great Depression + appeasement made war more likely by 1939?
Key Terms
Appeasement - a policy of making concessions to aggressive states to avoid war.
Versailles Treaty - 1919 treaty that imposed heavy terms on Germany, creating resentment and instability.
Rearmament - rebuilding military strength; in Nazi Germany it broke post-WWI limits.
Totalitarianism - a system where the state controls most aspects of public and private life (propaganda, censorship, repression).
Fascism - far-right ideology promoting dictatorship, extreme nationalism, and suppression of opposition (e.g., Italy under Mussolini).
Nazism - Hitler’s ideology combining dictatorship, extreme nationalism, racism, and anti-communism.
Militarism - belief that military power should guide national policy (strong in Japan’s leadership).

Worked Examples
Example 1: Cause-and-effect chain (straightforward)
Prompt: Explain one political and one economic cause of WWII by 1939.
• Political cause: The post-WWI settlement (Versailles + weak enforcement) was undermined as Hitler rejected limits and rearmed from 1933.
• Effect: Britain and France often delayed firm action (appeasement), encouraging further German moves (Rhineland, Austria, Czechoslovakia).
• Economic cause: The Great Depression (from 1929) increased unemployment and instability, helping radical parties gain power in Germany.
• Effect: Weak democracies had less public support to resist aggression, making escalation more likely.
Now you try: Explain one political and one ideological cause.

Example 2: Sequence and linking events (medium)
Prompt: Link appeasement to the 1938 Munich Agreement and then to war risk by 1939.
• Appeasement aimed to prevent war by granting concessions to Germany.
• Munich Agreement (Sept 1938) allowed Germany to take the Sudetenland.
• This signalled to Hitler that further expansion might still bring concessions rather than resistance.
• By 1939, Germany then moved to seize more territory (Poland), removing the “peace” space that appeasement had created.
Now you try: Link one 1936-1938 event to increased risk of war.

Example 3: “How far” reasoning (more complex)
Prompt: “The Great Depression was the main cause of WWII.” How would you respond using balanced reasoning?
• Agree partially: economic crisis helped dictators gain support and weakened democracies.
• But argue it wasn’t the only main cause: ideological aims (Nazism’s expansion) and political breakdown of enforcement (Versailles/League weakness) drove aggression.
• Conclude by weighing causes: economic factors enabled support, but dictatorship + rejection of peace arrangements created the direct path to war.
Now you try: Write a short balanced judgement: Which is more important, ideology or economic crisis, for 1933-39?

Answer Key
Q1: Any two:
• Germany rejected Versailles limits and rearmed (from 1933).
• League of Nations/collective security did not stop aggression (e.g., Manchuria, later Germany/Italy moves).
• Treaty enforcement weakened as democracies used appeasement instead of firm action.
Q2: Example structure (any valid details):
• Germany: Great Depression → unemployment → support for Nazi Party; Nazism promised national revival and expansion.
• Italy: Depression and social unrest → Mussolini’s fascists gained power; ideology stressed empire-building.
• Japan: Economic crisis and resource needs → militarists gained influence; ideology and expansion in Asia.
Q3: Example points:
• Rhineland remilitarised (1936) showed limits of enforcement.
• Anschluss (1938) and Munich Agreement (Sept 1938) encouraged further demands.
• By 1939, Germany’s move against Poland ended the “peace” space created by appeasement.
Q4: Higher-level judgement:
• Strong argument for ideology (Nazism’s expansionism, fascist militarism, Japanese militar
