League of Nations: membership (AQA GCSE History): Revision Notes
League of Nations membership
Initial membership and founding
When the League of Nations was established in 1920, it began with 42 founding member states. The organisation was heavily influenced by the major imperial powers that had emerged victorious from World War I, particularly Britain and France. These founding nations represented countries from across the globe, spanning Southeast Asia, Europe, and South America.
However, the membership was not truly representative of all nations. Many African territories could not join independently as they existed under League of Nations mandates or remained colonies of European member countries. This limitation reflected the colonial realities of the early 20th century.
The dominance of imperial powers in the League's founding membership created an inherent imbalance that would affect the organisation's legitimacy and effectiveness throughout its existence. This colonial framework meant that vast populations across Africa and Asia had no direct representation in international decision-making.
Motivations for joining the League
Countries sought membership in the League of Nations for several interconnected reasons. The primary motivation was preventing future warfare through collective diplomatic action. Nations believed that by working together within an international framework, they could resolve disputes peacefully before they escalated into armed conflicts.
Collective security represented another major draw - the idea that an attack on one member would be considered an attack on all, providing smaller nations with protection they couldn't achieve alone. Additionally, countries recognised opportunities for international cooperation on pressing global challenges including public health initiatives, combating human trafficking, and addressing the illegal drug trade.
Some nations also joined to gain influence over important issues such as colonial administration and disarmament negotiations, seeing League membership as a pathway to having their voices heard on the international stage.
The concept of collective security was revolutionary for its time, representing the first systematic attempt to create a global system where international law and cooperation would replace traditional military alliances and balance-of-power politics.
Notable exclusions and their reasons
Several significant nations remained outside the League initially, each for distinct political reasons:
Defeated Central Powers from World War I faced exclusion as part of their punishment. Germany, Austria, and Turkey were barred from joining, reflecting the victorious Allies' desire to maintain their wartime advantage in the post-war international system.
This exclusion policy was controversial even at the time, as it contradicted the League's stated goal of universal membership and collective security. Critics argued that excluding major powers would weaken the organisation's effectiveness and create resentment that could lead to future conflicts.
Russia (which became the USSR in 1922) was deliberately not invited to join. Britain and France harboured deep suspicions about the new communist government that had emerged from the Russian Revolution, viewing it as a potential threat to their own political systems.
Perhaps most significantly, the United States never became a member despite President Woodrow Wilson's central role in creating the League. The US Senate rejected membership, fearing that international commitments would compromise American sovereignty and draw the nation into future European conflicts. This reflected America's isolationist policy of avoiding entanglement in foreign affairs.
The absence of the United States was perhaps the most damaging blow to the League's credibility and effectiveness. Without American economic and military backing, the League lacked the power to enforce its decisions against major powers, fundamentally undermining its collective security mission.
Ironically, President Wilson travelled extensively across America in September 1919 campaigning for League membership, but his own country never joined.
Evolution of membership over time
League membership experienced significant changes throughout its existence. Austria and Bulgaria gained admission in 1924, while Germany was finally allowed to join in 1926 as international tensions began to ease. The USSR eventually became a member in 1934.
The organisation reached its peak membership of 58 countries between 1934 and 1935, representing the high point of international cooperation through the League system.
However, this period of maximum membership proved short-lived. Several nations departed due to various disputes and disagreements. Germany withdrew in 1933, Japan left in 1933, and Italy departed in 1937. Most dramatically, the USSR was expelled in 1939 following its invasion of Finland, marking a significant breakdown in the collective security system the League was designed to maintain.
The rapid departure of major powers in the 1930s revealed the League's fundamental weakness: it could not compel powerful nations to remain members or comply with its decisions. This exodus coincided with rising international tensions that would eventually lead to World War II.

Key Points to Remember:
- The League began in 1920 with 42 founding members, dominated by Britain and France as the major imperial powers
- Key exclusions included defeated nations (Germany, Austria, Turkey), communist Russia, and isolationist USA despite Wilson's involvement
- Countries joined seeking to prevent war through collective security and international cooperation on global issues
