Paper 1 case study anchor: German and Italian Expansion 1933–1940

· Paper 1: Prescribed subject 3 — The Move to Global War.
· Specified case study: German and Italian expansion (1933–1940).
· Official IB focus: causes of expansion, key events, and international responses to expansion.
· The IB expects students to explain expansion through fascism and Nazism, domestic economic issues, changing diplomatic alignments in Europe, the end of collective security, and appeasement.
· This is a source-based Paper 1 topic, so use knowledge to interpret sources, add precise context, compare perspectives, and build a supported judgement in the final question.
· You should know both Germany and Italy. Comparison is useful because both were revisionist fascist states, but Germany was more directly focused on overturning the post-war settlements, while Italy’s expansion was more about imperial prestige and Mediterranean/African power.

What this case study is really about

· This subtopic explains how two aggressive European dictatorships helped destroy the post-1919 international order.
· The central historical problem is not just “Hitler and Mussolini wanted war”; it is how ideology, economic pressure, revisionist aims, and weak international responses interacted.
· Expansion escalated because early challenges to the system were not stopped: Japan in Manchuria, Germany leaving the League, Italy in Abyssinia, and Germany in the Rhineland all showed that collective security could be evaded.
· Strong exam answers link cause → event → response → consequence: for example, Nazi revisionism encouraged the Rhineland remilitarization (1936); weak British/French response encouraged further German risk-taking; this made appeasement more likely and collective security weaker.

Causes of German expansion: Nazism, revisionism and economic pressure

· Impact of Nazism on German foreign policy: Hitler aimed to reverse the Treaty of Versailles, unite ethnic Germans, destroy perceived diplomatic restrictions, and pursue Lebensraum in eastern Europe.
· Post-war settlement grievances: Germany challenged territorial, military and diplomatic limits created after the First World War. This makes Versailles revisionism essential evidence for German expansion.
· Domestic economic issues: the Depression and unemployment strengthened support for aggressive policies promising recovery, rearmament and national revival. Rearmament also reduced unemployment and prepared for expansion.
· Autarky and rearmament: policies such as the Four-Year Plan (1936) made sense in an expansionist framework because Germany wanted economic self-sufficiency before major war.
· Exam use: show that German expansion was driven by both ideological aims and practical opportunity. A strong judgement might argue that ideology set the direction, while economic recovery and weak international responses made expansion possible.

Causes of Italian expansion: fascism, prestige and imperial ambition

· Impact of fascism on Italian foreign policy: Mussolini wanted to project strength, revise Italy’s “mutilated victory” after the First World War, and build a new empire associated with Roman-style greatness.
· Imperial prestige: Abyssinia (1935–1936) was useful because it could be presented as revenge for Italy’s earlier defeat at Adowa (1896) and as proof that Fascist Italy was a great power.
· Domestic economic issues: expansion could distract from economic weaknesses and offer resources, markets and prestige, although Italy’s economic base was weaker than Germany’s.
· Strategic aims: expansion in Abyssinia and Albania helped Mussolini claim influence in Africa and the Mediterranean/Balkans.
· Exam use: Italy is best used to show how fascist ideology, prestige politics and League weakness encouraged aggression, but also how Mussolini’s expansion was more limited and opportunistic than Hitler’s.

Changing diplomatic alignments and the collapse of collective security

· The syllabus explicitly links expansion to changing diplomatic alignments in Europe, the end of collective security, and appeasement.
· Stresa Front (1935): Britain, France and Italy briefly opposed German revisionism after Hitler’s rearmament moves, but the front collapsed after Italy invaded Abyssinia.
· Abyssinia (1935–1936): League sanctions were limited and ineffective; Britain and France were reluctant to alienate Mussolini because they still wanted Italy as a counterweight to Germany.
· Rome–Berlin Axis (1936): Italy moved closer to Germany after the Abyssinian crisis, weakening the possibility of a united front against Hitler.
· Pact of Steel (1939): German–Italian cooperation became more formal, showing that the diplomatic balance in Europe had shifted towards an aggressive revisionist bloc.
· Nazi–Soviet Pact (August 1939): Germany neutralized the danger of immediate Soviet opposition before attacking Poland, making the outbreak of war more likely.
· Exam use: use diplomatic alignments to explain why expansion became easier over time. The key argument is that aggressors did not act in isolation; they responded to divisions among Britain, France, Italy and the USSR.

German challenges to the post-war settlements 1933–1938

· 1933 — Germany leaves the League of Nations: challenged the international system and showed rejection of collective security.
· 1935 — rearmament and conscription: directly challenged Versailles military restrictions and made future expansion more credible.
· 1935 — Saar returns to Germany: legal plebiscite success boosted Hitler’s prestige and strengthened claims that ethnic Germans should be reunited.
· 1935 — Anglo-German Naval Agreement: Britain accepted German naval rearmament up to a limit, weakening the united enforcement of Versailles.
· 1936 — Rhineland remilitarization: Germany violated the Versailles and Locarno settlements; Britain and France did not use force. This was a turning point because it improved Germany’s strategic position and encouraged further risks.
· 1938 — Anschluss with Austria: Germany absorbed Austria, strengthening the idea of uniting German-speaking peoples and increasing Germany’s resources and strategic reach.
· 1938 — Sudetenland crisis and Munich Agreement: Britain and France accepted German acquisition of the Sudetenland in the name of appeasement, badly weakening Czechoslovakia.
· Exam use: this sequence is ideal for “to what extent” judgements. The pattern shows escalation: diplomatic withdrawal → military revisionism → territorial expansion → destruction of collective security.

The Rhineland remilitarization (1936) was one of the clearest tests of the post-war settlement. It is especially useful for explaining how limited international response encouraged German escalation. Source

Italian expansion: Abyssinia, Albania and entry into war

· Abyssinia (1935–1936): Italy invaded an independent League member, exposing the weakness of the League of Nations and collective security.
· League response to Abyssinia: sanctions did not include the most decisive measures, such as fully effective oil sanctions or closing the Suez Canal. This made the response look cautious rather than collective and determined.
· Hoare–Laval Pact (1935): the secret Anglo-French proposal to give Italy large parts of Abyssinia damaged faith in collective security because it suggested appeasement of aggression.
· Albania (1939): Italy occupied Albania, showing Mussolini’s desire to keep pace with Hitler after German gains in Austria and Czechoslovakia.
· Entry into the Second World War (June 1940): Italy joined after Germany’s early victories made war appear profitable; this showed opportunism rather than full military readiness.
· Exam use: Italy is the best evidence for the failure of the League. It also helps compare Mussolini’s prestige-driven, opportunistic expansion with Hitler’s more systematic destruction of the European settlement.

German expansion 1938–1939 and the outbreak of war

· Anschluss (March 1938): Germany incorporated Austria; this advanced German-speaking unity and broke the Versailles/St Germain settlement.
· Sudetenland and Munich (September 1938): Hitler used ethnic German claims and pressure to gain territory without war; Britain and France chose appeasement.
· Occupation of the rest of Czechoslovakia (March 1939): this damaged the argument that Hitler only wanted self-determination for Germans because non-German territory was occupied.
· Pact of Steel (May 1939): Germany and Italy formalized their alliance, showing the consolidation of fascist diplomatic alignment.
· Nazi–Soviet Pact (August 1939): removed the immediate threat of a two-front war and included secret understandings over eastern Europe.
· Poland and outbreak of war (September 1939): German invasion triggered British and French declarations of war, showing the limit of appeasement.
· Exam use: distinguish 1938 appeasement from 1939 deterrence. Britain and France tolerated earlier revisionism, but after Prague and Poland they shifted towards guarantees and war.

The Munich Agreement (1938) is the key visual example of appeasement. It helps students discuss whether Britain and France were buying time, avoiding war, or enabling further aggression. Source

International responses to German aggression 1933–1938

· Limited enforcement: Germany’s withdrawal from the League, rearmament and conscription were condemned but not stopped by force.
· Appeasement: Britain and France often accepted revisionist claims when they seemed limited, partly because of war-weariness, economic weakness, fear of communism, and doubts about Versailles.
· Rhineland response (1936): France did not act without British support; Britain often viewed the move as Germany entering its own “backyard.” This encouraged Hitler.
· Munich response (1938): Britain and France accepted Sudetenland transfer to Germany without Czechoslovakia having real control over the outcome.
· Analysis: appeasement was not simply weakness; it was also a policy shaped by military unpreparedness, public fear of war and uncertainty over whether Hitler’s demands were limited.
· Exam use: for source questions, look for perspective. A British source may frame appeasement as peacekeeping; a later historian may frame it as enabling aggression.

International responses to Italian aggression 1935–1936

· League of Nations: condemned Italy but imposed only limited sanctions.
· Britain and France: prioritized European balance against Germany, so they avoided a full confrontation with Mussolini.
· Hoare–Laval Pact: showed that great powers might sacrifice Abyssinia to preserve relations with Italy.
· Result: Italy completed conquest, the League was discredited, and Mussolini moved closer to Hitler.
· Analysis: Abyssinia is one of the strongest examples of the end of collective security because the victim was a League member and the aggressor was still rewarded in practice.
· Exam use: use Abyssinia to argue that failure over Italy encouraged Germany by proving the international system lacked enforcement power.

International response to German and Italian aggression 1940

· By 1940, appeasement had largely collapsed because Germany’s actions in Prague (1939) and Poland (1939) showed expansion was not limited to self-determination.
· Britain and France were already at war with Germany from September 1939.
· Italy entered the war in June 1940, after Germany’s victories made intervention appear advantageous.
· The response to Italy in 1940 was different from Abyssinia: Italy was no longer treated as a state to be kept away from Germany, but as part of the Axis war effort.
· Exam use: contrast 1935–1936 caution with 1940 open war. This shows how responses changed as aggression escalated and diplomatic options narrowed.

Compact evidence bank: best examples to memorise

· Germany leaves the League (1933): demonstrates rejection of collective security; use for early German challenge to the international system.
· Rearmament and conscription (1935): demonstrates direct challenge to Versailles; use for revisionism and preparation for expansion.
· Rhineland remilitarization (1936): demonstrates high-risk German challenge and weak Anglo-French response; use as turning point.
· Abyssinia (1935–1936): demonstrates Italian imperial ambition and League failure; use for collapse of collective security.
· Anschluss (1938): demonstrates German ethnic-national expansion and failure to enforce settlements.
· Munich Agreement/Sudetenland (1938): demonstrates appeasement and short-term avoidance of war at the cost of Czechoslovakia.
· Occupation of Czechoslovakia (March 1939): demonstrates shift from revisionism/self-determination to open domination; use to explain why British policy hardened.
· Nazi–Soviet Pact and Poland (1939): demonstrates diplomatic preparation for war and the immediate trigger for Britain and France entering war.

Germany vs Italy: comparison points that score well

· Ideology: Germany’s Nazism had a stronger racial and territorial programme, especially Lebensraum; Italy’s fascism emphasized prestige, empire and great-power status.
· Economic drivers: both used expansion to address domestic pressures, but Germany’s rearmament and autarky were more systematically linked to future war.
· Methods: Germany used staged revisionism, plebiscites, threats, diplomacy and then war; Italy relied more on colonial conquest and opportunistic moves.
· International response: Germany benefited from appeasement in Europe; Italy exposed League weakness in Abyssinia and then moved towards Germany.
· Consequences: German expansion directly caused the outbreak of war in Europe in 1939; Italian expansion weakened collective security earlier and helped shift diplomatic alignments.
· Judgement: Italy helped destroy collective security, but Germany posed the greater direct threat to the European territorial order.

How to use this in Paper 1 answers

· For source comprehension, identify whether a source is about causes, events, or responses; do not just describe what happened.
· For OPVL, link origin and purpose to context: for example, a British political speech in 1938 may defend appeasement, while a later historian may judge it with hindsight.
· For compare and contrast, compare the message or perspective of sources about appeasement, League weakness, or Hitler/Mussolini’s aims.
· For the final Paper 1 judgement question, combine source evidence with precise own knowledge such as Rhineland (1936), Abyssinia (1935–1936), Munich (1938) and Nazi–Soviet Pact (1939).
· Strong answers avoid narrative and instead explain why expansion occurred, why responses failed, and how each stage made later aggression more likely.

Strong judgement lines you can adapt

· On causes: “Ideology shaped the aims of German and Italian expansion, but opportunity created by weak international responses determined how far expansion could go before 1940.”
· On appeasement: “Appeasement delayed war in the short term, but it also encouraged further German demands by proving that Britain and France were reluctant to enforce the post-war settlement.”
· On collective security: “The Abyssinian Crisis was more damaging to the League than earlier German moves because it exposed that even aggression against a League member would not be reversed.”
· On comparison: “Germany and Italy were both revisionist fascist powers, but Germany’s expansion was more systematic, ideologically radical and directly responsible for the outbreak of war in Europe.”

Exam traps or common mistakes

· Do not write a general biography of Hitler or Mussolini; keep every point tied to expansion.
· Do not treat appeasement as only cowardice; explain military, economic, diplomatic and public-opinion reasons.
· Do not confuse Abyssinia (1935–1936) with Albania (1939); Abyssinia is mainly about League failure, Albania about Mussolini keeping pace with Hitler.
· Do not stop German expansion at Munich; Prague (March 1939) and Poland (September 1939) are essential for explaining why war broke out.
· Do not list events without analysis; each event should prove something about causes, methods, responses or consequences.
· Do not ignore Italy in a question on German and Italian expansion; even if Germany dominates, Italy is central to the collapse of collective security.
