The collapse of collective security: the reasons for and consequences of…

The idea

The collapse of collective security was starkly demonstrated by the League of Nations' failure to resolve the Manchurian (1931) and Abyssinian (1935) Crises. Reasons for failure included the absence of major powers like the USA, the slow bureaucratic processes of the League (such as the Lytton Report), and the self-interest of Britain and France, who prioritised their own empires and the Stresa Front over collective action. The consequences were catastrophic: the League was exposed as powerless against aggressive expansionism, economic sanctions were proven ineffective (as seen with the Hoare-Laval Pact), and revisionist powers were emboldened. Ultimately, these failures destroyed the credibility of the League and paved the way for further aggression.

What earns the marks

• Analyse the structural and membership weaknesses of the League that hindered decisive action in Manchuria, such as the absence of the USA and the requirement for unanimous decisions.
• Explain how British and French self-interest, particularly the desire to maintain Italy as an ally against Germany, undermined the response to the Abyssinian Crisis.
• Evaluate the failure of economic sanctions in Abyssinia, noting the exclusion of vital resources like oil and the continued use of the Suez Canal by Italian forces.
• Assess the long-term consequences of these crises, specifically how they emboldened Hitler and Mussolini, leading to the Rome-Berlin Axis and the definitive collapse of collective security.

Common mistakes and how to put them right

• Confusing the timelines and details of the two crises.

  Put it right: Clearly separate the Manchurian Crisis (1931, Lytton Report, Japan) from the Abyssinian Crisis (1935, Hoare-Laval Pact, Italy).

• Stating the League did absolutely nothing.

  Put it right: Specify that the League did act through moral condemnation and limited sanctions, but these actions were fundamentally ineffective.

• Blaming the failure solely on the League's structure.

  Put it right: Balance structural weaknesses with the lack of political will from leading members, particularly Britain and France.

Exam tips

• Use the Hoare-Laval Pact as a prime example of how the self-interest of major powers directly contradicted and undermined the principles of collective security.
• Compare the reasons for failure in both crises to build a strong analytical argument about the inherent flaws of the League of Nations.
• Explicitly link the failure in Abyssinia to the subsequent aggressive actions of Germany, such as the remilitarisation of the Rhineland.
