Lesson 2: Core Concepts: the league in the 1930s

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on the league in the 1930s. Check them against the notes below.

Main Content (35 minutes)

Key Fact: On 18 September 1931, Japan used the "Mukden Incident" - an explosion on the Japanese-owned South Manchurian Railway - as a pretext to invade Manchuria, a region of northern China. Japan occupied the entire province and set up the puppet state of "Manchukuo" in February 1932. The League's response was slow, weak, and ultimately ineffective.
Key Fact: In October 1935, Italy invaded Abyssinia (modern Ethiopia), one of the few independent African nations. The League imposed economic sanctions on Italy but they were half-hearted and failed to stop the invasion. By May 1936, Italy had conquered Abyssinia. The crisis was the League's most humiliating failure and effectively destroyed it as a peacekeeping body.
Key Fact: The Great Depression that followed the 1929 Wall Street Crash fundamentally changed the international environment. Economic crisis made nations more aggressive, more self-interested, and less willing to cooperate through the League.
Key Fact: The World Disarmament Conference opened in Geneva on 2 February 1932 with 60 nations represented. It was the League's most ambitious attempt to reduce armaments. After nearly 18 months of negotiation, it collapsed completely in June 1934 without achieving any significant agreement.
Key Fact: By 1936, collective security was effectively dead. The League had failed to stop Japan in Manchuria, failed to stop Italy in Abyssinia, and failed to achieve disarmament. When Hitler remilitarised the Rhineland in March 1936, no one even asked the League to act. The League continued to exist technically until 1946, but as a peacekeeping body it was finished by 1936.
History Exam Tips — The League in the 1930s: 1. For The League in the 1930s, include specific factual detail: dates, names, events and statistics where relevant 2. For source questions, analyse provenance (who, when, why, audience) before using the content 3. In evaluation questions, discuss multiple factors and weigh their relative significance 4. Always link back to the question focus — don't just narrate what happened with The League in the 1930s 5. Use phrases like 'the most significant factor was... because...' to show analytical judgement
ItemDetail
Incomplete sanctionsOil was NOT included in sanctions; coal and steel were NOT included; Italy could still import war materials
Suez Canal not closedBritain controlled the canal but did not close it to Italian ships - the easiest way to stop the invasion
Self-interestBritain and France wanted Italy as an ally against Hitler; they feared pushing Mussolini towards Germany
Hoare-Laval PactSecretly betrayed Abyssinia; showed the League's leading members were not committed to collective security
Stresa FrontBritain, France and Italy had agreed in April 1935 to resist German rearmament; Britain/France didn't want to lose Italy
No military actionThe League had no army; Britain and France were unwilling to send troops
No armyGreat Depression made nations self-interested
No USARise of dictatorships (Hitler, Mussolini)

Practice (10 minutes)

Q: Explain why the League failed to stop Japan in Manchuria. (4 marks)

Answer: The League failed over Manchuria because: Manchuria was too far from Europe for the League to project power; the League had no army to force Japan out; economic sanctions were useless without America (Japan's biggest trading partner); the Lytton Commission took over a year to report, by which time Japan was firmly established; and Britain and France were unwilling to commit forces to a distant conflict during the Depression.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Q1: Explain why the League failed to stop Japan in Manchuria. (4 marks)

Answer: The League failed over Manchuria because: Manchuria was too far from Europe for the League to project power; the League had no army to force Japan out; economic sanctions were useless without America (Japan's biggest trading partner); the Lytton Commission took over a year to report, by which time Japan was firmly established; and Britain and France were unwilling to commit forces to a distant conflict during the Depression.

Q2: How important was the Hoare-Laval Pact in destroying the League's credibility? (8 marks)

Answer: The Hoare-Laval Pact was very important in destroying the League's credibility. It revealed that Britain and France - the League's most powerful members - were secretly willing to give Italy most of Abyssinia, completely betraying the principle of collective security. When the plan was leaked, it showed that the League's leading members were not committed to its principles. However, the League's credibility was already damaged by the Manchurian failure (1931-33), and the sanctions imposed on Italy were already inadequate (no oil embargo, Suez Canal open). The Pact was the final blow to the League's moral authority, but the failure was already well underway.

Q3: "The Abyssinian Crisis was the League's worst failure." How far do you agree? (12 marks)

Answer: The Abyssinian Crisis was the League's worst failure because: it involved a permanent Council member (Italy) openly invading another League member; the League did impose sanctions but made them deliberately ineffective; the Hoare-Laval Pact showed the leading members actively undermining collective security; and Italy simply conquered Abyssinia and walked out of the League. However, Manchuria was also a catastrophic failure that came first and set the pattern; the Disarmament Conference failure was equally important for European security; and the Rhineland remilitarisation (1936) was arguably more dangerous but the League was not even consulted. Abyssinia was the most humiliating failure because it showed the League's leading members actively betraying the organisation.

Q4: Explain why the Disarmament Conference failed. (8 marks)

Answer: The Disarmament Conference failed because: Germany demanded equality of armaments with France; France insisted on security guarantees before disarming; no nation was willing to disarm first, creating a deadlock; Hitler walked out in October 1933, using the failure as propaganda to justify German rearmament; and there was no trust between the powers. The fundamental problem was that disarmament required cooperation and trust, which the Depression and rise of dictatorships had destroyed. France would not disarm while Germany threatened; Germany would not accept inequality; and no other nation would lead by example.

Q5: "The League failed because of its structural weaknesses, not because of circumstances." How far do you agree? (16 marks)

Answer: The League failed because of both structural weaknesses and circumstances, but the structural weaknesses were more fundamental. The League had no army, meaning it could never enforce decisions; the USA never joined, removing the world's greatest power; the unanimity rule meant any member could veto action; and Britain and France were not genuinely committed. These were built-in flaws that would have undermined any peacekeeping body. However, circumstances made things worse: the Depression made nations self-interested; the rise of Hitler and Mussolini created aggressors the League was not designed to handle; and public anti-war sentiment limited what governments could do. Without the structural weaknesses, the League might have coped with the circumstances; but the weaknesses made failure almost inevitable regardless of circumstances.

Exam-Style Question

Attempt a past-paper style question on the league in the 1930s from the exam board past paper finder (see Resources), then mark it against the scheme.

Exam Tips: Know the exact dates: Manchuria invasion 18 September 1931; Italy invades Abyssinia 3 October 1935; Hoare-Laval Pact December 1935; Haile Selassie's speech 30 June 1936 | Manchuria and Abyssinia are the two KEY failures - always compare them in your answers | The Hoare-Laval Pact is crucial evidence that Britain and France undermined the League from within | Always explain WHY sanctions failed: no oil embargo, Suez Canal open, no American participation | The Great Depression is the key CONTEXTUAL factor for explaining the shift from 1920s success to 1930s failure | Haile Selassie's warning ("It is us today. It will be you tomorrow") is a powerful quote to use | For "why did the League fail"
Common Errors: Watch Out! Students often think the treaty of versailles was entirely unfair. Wrong: The Treaty of Versailles was entirely unfair Correct: While harsh, some terms were reasonable. The reparations were later reduced. Germany's treatment of Russia at Brest-Litovsk 1918 was far harsher. Students often think the league of nations was a complete failure. Wrong: The League of Nations was a complete failure Correct: The League had significant successes in the 1920s: resolving the Aaland Islands dispute, the Greece-Bulgaria border conflict, and extensive humanitarian work. Students often think appeasement was simply cowardice. Wrong: Appeasement was simply cowardice Correct: Appeasement had logical
Stretch & Challenge (Grade 8-9):
