The League of Nations, abbreviated as LN or LoN, (French: Société des Nations [sɔsjete de nɑsjɔ̃], abbreviated as “SDN” or “SdN” and meaning “Society of Nations”) was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace.[1] It was founded on 10 January 1920 following the Paris Peace Conference that ended the First World War; in 1919 U.S. president Woodrow Wilson won the Nobel Peace Prize for his role as the leading architect of the League.
The organisation’s primary goals, as stated in its Covenant, included preventing wars through collective security and disarmament and settling international disputes through negotiation and arbitration.[2] Other issues in this and related treaties included labour conditions, just treatment of native inhabitants, human and drug trafficking, the arms trade, global health, prisoners of war, and protection of minorities in Europe.[3] The Covenant of the League of Nations was signed on 28 June 1919 as Part I of the Treaty of Versailles, and it became effective together with the rest of the Treaty on 10 January 1920. The first meeting of the Council of the League took place on 16 January 1920, and the first meeting of Assembly of the League took place on 15 November 1920.
The diplomatic philosophy behind the League represented a fundamental shift from the preceding hundred years. The League lacked its own armed force and depended on the victorious First World War Allies (France, the United Kingdom, Italy and Japan were the permanent members of the Executive Council) to enforce its resolutions, keep to its economic sanctions, or provide an army when needed. The Great Powers were often reluctant to do so. Sanctions could hurt League members, so they were reluctant to comply with them. During the Second Italo-Abyssinian War, when the League accused Italian soldiers of targeting Red Cross medical tents, Benito Mussolini responded that “the League is very well when sparrows shout, but no good at all when eagles fall out.”[4]
