ARISING from the ashes of the catastrophic Great War the League of Nations was founded in 1919 on high Liberal ideals but with the most challenging of tasks – “to promote international cooperation and achieve peace and security “. Ultimately, the League failed to live up to its mission statement, in the end floundering badly in its efforts to stop aggressive acts by rogue states and prevent the outbreak of a second world war.

Fear of failure?
The interwar years were marked by numerous incidences of disputes between states over territories and borders. One of the most apparent shortcomings of the League (LoN) was its choosiness in deciding which conflicts to intervene in and which not to…under the League’s foundation secretary-general Eric Drummond, the approach was a cautious and selective one, prompted by the fear that failure might undermine the body’s authority in the international arena (‘League of Nations’, History, Upd. 23-Mar-2023, www.history.com).

The LoN’s reluctance to involve itself in every international dispute also came down to the inherent weakness of its position. Where one of the discordant parties was not a member of the LoN and especially a larger power, the capacity of the organisation to effect a viable resolution was severely curtailed. The LoN declined to intervene when Soviet Russia attacked a port in Persia in 1920 in the belief that non-member Russia would disregard its authority. The LoN’s dispute resolution capacity was similarly neutralised in the 1923 Corfu incident…Mussolini’s Italy had bombed and invaded the Greek island leading to Greece asking the LoN to intervene but Mussolini, though a member, simply ignored the LoN’s attempts to mediate in the conflict.

Structural and functional weakness, the power of single veto
The League’s organisational structure proved a further impediment to the realisation of LoN’s primary purpose of maintaining inter-governmental peace. Unlike its successor world body the UN, all LoN members, whether powerful or minor players on the world stage, had equal voting rights in the assembly with the making of decisions requiring unanimity from the members, the necessity of universal consent a recipe for perpetual indecision and impasse (‘Why Did the League of Nations Fail?’, Luke Tomes, History Hit, 27-Oct-2020, www.historyhit.com).

“League of Victors”, minus the US
Critically, several of the more internationally significant nations were excluded from the new world body. The United States by choice excluded itself from membership, a massive setback to a world body’s claim to inclusiveness. In the aftermath of WWI and the Russian Revolution the vanquished Germans and the USSR🅐, were prevented from joining. At LoN’s point of peak membership (1935) there were 58 League nations, at its dissolution (1946) this had dwindled to only 23 members.

League idealism trumped by real politik
Viewed through rose-coloured glasses the LoN’s proponents assumed the organisation’s creation would herald in an era of internationalism. Their naïveté between the wars was exposed by the rise of ultra-nationalism especially when it coalesced in a totalitarian regime (acerbated by the Great Depression): for individual nations, League of Nations or no League of Nations, fundamental self-interest remained paramount (Tomes).

Expansionism by far-right regimes unchecked
In the 1930s, in a deteriorating international climate, the eruption of serious crises demonstrated the LoN’s impotence vis-a-vís aggressively inclined renegade states. When the imperial Japanese army invaded Manchuria (Northeast China)—a clear breach of Article 10 of the League’s Covenant (disrespecting another member’s sovereignty)—the LoN took no action against the offending nation. When the Commission eventually ruled that Manchuria should be returned to China, Tokyo responded by simply relinquishing its League membership and staying put🅑. When Fascist Italy’s provoked a colonial expansionist war against a much weaker state Abyssinia (Ethiopia) in 1935, the LoN’s condemnation and subsequent economic sanctions on the Italian aggressors were undermined by the great powers Britain and France who in a secret deal green-lighted Italy’s action in East Africa. The British and French concession to Italy was meant to help lure Mussolini away from allying with Germany and Hitler. Once again particular countries put self-interest ahead of the collective security goals of the LoN. Rome’s response to the League’s threats, like Japan and Germany before it, was to to pull Italy out of the LoN. The Ethiopian crisis damaged the League’s reputation further and reinforced the paucity of its peacekeeping role.

The LoN failed miserably in its stated objective of bringing about international disarmament, on the contrary under its watch rearmament and military buildup in Germany, Italy, Japan and the USSR greatly expanded in the 1930s. Without armed forces of its own the LoN was reliant on the great powers to enforce its authority which they were generally unwilling to do. The League in time of state conflicts thus fell back on negotiation and arbitration and the threat of sanctions (never fully implemented), in which it had a sorry track record (‘The League is Dead. Long Live the United Nations’, The National WWII Museum, 19-Apr-2022, www.nationalww2museum.org).

Footnote: The League’s legacy
While the League of Nations was unable to realise its raison d’être, a workable system of international cooperation and security, there was a positive side to its existence. Where smaller nations were involved the LoN did have some success in settling disputes of neighbouring countries peacefully, eg, between Finland and Sweden in 1921 over the Aland Islands. The organisation’s activities embraced many issues of concern and urgency in its day, including efforts to curb the opium traffic; tackling the scourge of tropical diseases like malaria and leprosy; post-WWI refugee crisis and POW repatriation; recognising the rights of ethnic minorities; regulation of workers’ wages and conditions; curtailing the arms trade. While not always successful in these projects the pioneering LoN can be credited for providing a framework for its successor the UN to carry out its humanitarian work.
