H13: The League in the 1930s
The Manchurian crisis, Abyssinia, the Hoare-Laval Pact, the impact of the Depression, disarmament failures, and the collapse of collective security.
🇯🇵 The Manchurian Crisis (1931-1933)
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.
Events
- 18 September 1931: An explosion damaged the Japanese railway near Mukden (Shenyang). Japan blamed Chinese dissidents, though evidence suggests Japan staged the incident
- Japan invaded Manchuria, claiming it was acting in self-defence to protect its interests
- By February 1932, Japan had occupied all of Manchuria and established the puppet state of "Manchukuo" with the deposed Chinese Emperor Puyi as figurehead
- China appealed to the League of Nations for help
- The League sent a commission of inquiry led by Lord Lytton, which took over a year to report
- October 1932: The Lytton Report concluded that Japan had NOT acted in self-defence and Manchuria should be returned to China
- February 1933: The Assembly voted 42-1 to accept the Lytton Report. Japan was the sole opponent
- 27 March 1933: Japan walked out of the League of Nations entirely
Why the League Failed Over Manchuria
- Distance: Manchuria was thousands of miles from Europe; the League had no forces in the region
- No army: The League could not send troops to force Japan out; Britain and France were unwilling to provide troops
- Economic sanctions weak: Japan's main trading partner was the USA, which was NOT in the League - sanctions would have little effect
- Slow response: The Lytton Commission took over a year to report; by then, Japan was firmly established
- Self-interest: Britain and France did not want to antagonise Japan; they had colonies in Asia to protect
- Other crises: The world was in the Great Depression; European powers were focused on domestic problems
Significance of Manchuria
Manchuria was the first major test of the League's collective security system - and it failed completely. Japan, a permanent Council member, had invaded another country and the League could do nothing. Japan simply walked out when condemned. This showed: (1) the League could not stop a major power; (2) economic sanctions were useless without American cooperation; (3) the League had no military force; and (4) the unanimity rule and national self-interest paralysed action. The Manchurian crisis destroyed the League's credibility and emboldened other aggressors.
🇮🇹 The Abyssinian Crisis (1935-1936)
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.
Events
- December 1934: The Wal Wal Incident - a clash between Italian and Abyssinian forces at a border oasis gave Mussolini his pretext
- January 1935: Abyssinia appealed to the League; France and Britain tried to mediate but did not confront Mussolini
- 3 October 1935: Italy invaded Abyssinia with 400,000 troops; the Abyssinian army was poorly equipped
- The League condemned Italy as the aggressor and imposed economic sanctions in November 1935
- However, sanctions did NOT include oil - the one resource Italy desperately needed
- The Suez Canal, controlled by Britain, was NOT closed to Italian ships shipping supplies to the war
- December 1935: The Hoare-Laval Pact was leaked to the press - a secret plan by Britain and France to give Italy two-thirds of Abyssinia
- May 1936: Italy completed the conquest of Abyssinia; Emperor Haile Selassie fled to Britain
- 30 June 1936: Haile Selassie addressed the League Assembly in Geneva, warning: "It is us today. It will be you tomorrow."
- July 1936: The League lifted sanctions; Italy left the League in 1937
The Hoare-Laval Pact (December 1935)
The Hoare-Laval Pact:
British Foreign Secretary Samuel Hoare and French Prime Minister Pierre Laval secretly proposed giving Italy most of Abyssinia in exchange for a small Italian withdrawal. When the plan was leaked to the French press, there was international outrage. Hoare was forced to resign. The Pact showed that Britain and France were willing to abandon the League and sacrifice a small nation to appease Mussolini. It destroyed any remaining credibility the League had as a defender of collective security.

Why the League Failed Over Abyssinia
| Reason for Failure | Detail |
|---|---|
| Incomplete sanctions | Oil was NOT included in sanctions; coal and steel were NOT included; Italy could still import war materials |
| Suez Canal not closed | Britain controlled the canal but did not close it to Italian ships - the easiest way to stop the invasion |
| Self-interest | Britain and France wanted Italy as an ally against Hitler; they feared pushing Mussolini towards Germany |
| Hoare-Laval Pact | Secretly betrayed Abyssinia; showed the League's leading members were not committed to collective security |
| Stresa Front | Britain, France and Italy had agreed in April 1935 to resist German rearmament; Britain/France didn't want to lose Italy |
| No military action | The League had no army; Britain and France were unwilling to send troops |
Example: Haile Selassie's Speech
On 30 June 1936, Emperor Haile Selassie addressed the League Assembly in Geneva. He made a powerful speech warning that the League's failure would encourage further aggression: "It is us today. It will be you tomorrow." He was ignored. Italian journalists jeered him. The League did nothing effective. His warning proved prophetic - within months, Hitler remilitarised the Rhineland (March 1936), calculating correctly that the League and its leading members would not act.
📉 The Impact of the Great Depression
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.
How the Depression Weakened the League
- Protectionism: Countries raised tariffs and put up trade barriers, making economic sanctions less effective
- Rise of dictatorships: Economic hardship helped bring Hitler (1933) to power and emboldened Mussolini; both rejected international cooperation
- National self-interest: Countries focused on domestic problems rather than international obligations; Britain and France were unwilling to spend money on enforcing League decisions
- Military aggression increased: Japan invaded Manchuria (1931) partly because the Depression hit its exports; Italy invaded Abyssinia (1935) to distract from economic problems at home
- Unemployment: Mass unemployment in Britain and France made governments reluctant to risk war; public opinion was strongly anti-war
- Reparations and war debts collapsed: The international financial system that the League relied on broke down
🔫 Disarmament Failures
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.
Why Disarmament Failed
- Germany's demand for equality: Germany demanded the right to equal armaments with other nations; France refused, insisting on security guarantees first
- France's security fears: France had been invaded by Germany twice in 50 years (1870, 1914); it would not disarm without guaranteed protection
- Other nations wouldn't disarm first: No country was willing to reduce its own arms before others did - a classic "prisoner's dilemma"
- Hitler's withdrawal: In October 1933, Hitler walked out of the Conference and the League, beginning German rearmament
- Lack of trust: Without trust between nations, disarmament was impossible
- Military industries: Arms manufacturers lobbied against disarmament; many economies depended on military production
Example: Hitler and Disarmament
Hitler cleverly exploited the disarmament issue. He demanded "equality" for Germany - the right to have the same arms as other nations. When this was refused, he walked out of the Conference (October 1933), blaming the other powers for their "hypocrisy" in keeping their arms while denying Germany the same right. This was brilliant propaganda: it made Germany look reasonable and the League look unfair. In March 1935, Hitler openly announced German rearmament - introducing conscription and building an air force - directly violating the Treaty of Versailles.
💔 The Collapse of Collective Security
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.
The Chain of Failure
The League's Collapse:
Manchuria 1931 → Showed the League could not stop a major power
Disarmament Conference 1932-34 → Showed the League could not reduce armaments
Germany leaves League 1933 → Removed Europe's most dangerous state
Abyssinia 1935-36 → Showed the League's leading members were not committed
Rhineland 1936 → No one even asked the League to act
→ Collective security was dead
Manchuria 1931 → Showed the League could not stop a major power
Disarmament Conference 1932-34 → Showed the League could not reduce armaments
Germany leaves League 1933 → Removed Europe's most dangerous state
Abyssinia 1935-36 → Showed the League's leading members were not committed
Rhineland 1936 → No one even asked the League to act
→ Collective security was dead
Why the League Failed: Summary
| Structural Weaknesses | Circumstantial Factors |
|---|---|
| No army | Great Depression made nations self-interested |
| No USA | Rise of dictatorships (Hitler, Mussolini) |
| Unanimity rule | Public opinion anti-war after WWI |
| Tied to Versailles (seen as "winners' club") | Appeasement replaced collective security |
| Slow decision-making | Manchuria and Abyssinia were far from Europe |
| Britain and France not committed | Lack of trust between nations |

✅ Answers
- 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.
- 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.
- 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.
- 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.
- 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.

⚠️ 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 reasons: Britain's military was unready, the public feared another war, and the USSR was seen as a greater threat than Germany.

12 marks: Explain why the League failed in the 1930s.
The League failed in the 1930s because it could not stop aggression by major powers. The Manchurian crisis (18 September 1931) was the first major test: Japan used the Mukden Incident as a pretext to invade Manchuria and set up the puppet state of "Manchukuo" by February 1932. The League sent the Lytton Commission, which took over a year to report. When the Assembly voted 42-1 to accept the Lytton Report in February 1933, Japan simply walked out of the League. The League failed because Manchuria was too far from Europe, it had no army to force Japan out, economic sanctions were useless without the USA (Japan's biggest trading partner), and Britain and France prioritised their own colonial interests in Asia over collective security.
The Abyssinian crisis (October 1935) was even more damaging. Italy invaded Abyssinia with 400,000 troops on 3 October 1935. The League imposed economic sanctions but deliberately excluded oil — the one resource Italy desperately needed. Britain did not close the Suez Canal to Italian ships. The Hoare-Laval Pact (December 1935) was the most damning evidence of the League's failure: British Foreign Secretary Samuel Hoare and French Prime Minister Pierre Laval secretly proposed giving Italy two-thirds of Abyssinia, completely betraying collective security. When the plan was leaked, Hoare was forced to resign, but the damage was done. Emperor Haile Selassie warned the League Assembly on 30 June 1936: "It is us today. It will be you tomorrow." Italy completed the conquest and left the League in 1937.
The Great Depression after the 1929 Wall Street Crash made nations more aggressive and self-interested, undermining the cooperative spirit of the 1920s. The Disarmament Conference (February 1932–June 1934) collapsed completely when Hitler walked out in October 1933 and began German rearmament. No collective security meant that when Hitler remilitarised the Rhineland in March 1936, no one even asked the League to act. In conclusion, the League failed because its structural weaknesses (no army, no USA, unanimity rule) were exposed by the determined aggression of major powers, and its own leading members — Britain and France — were not genuinely committed to collective security when it conflicted with their national interests.
