League of Nations Union

The League of Nations Union (LNU) was an organization formed in October 1918 in the United Kingdom to promote international justice, collective security and a permanent peace between nations based upon the ideals of the League of Nations. The League of Nations was established by the Great Powers as part of the Paris Peace Treaties, the international settlement that followed the First World War. The creation of a general association of nations was the final one of President Woodrow Wilson's Fourteen Points. The LNU became the largest and most influential organisation in the British peace movement. By the mid-1920s, it had over a quarter of a million registered subscribers and its membership eventually peaked at around 407,775 in 1931. By the 1940s, after the disappointments of the international crises of the 1930s and the descent into World War II, membership fell to about 100,000.

The LNU was formed on 13 October 1918 by the merger of the League of Free Nations Association and the League of Nations Society, two older organisations already working for the establishment of a new and transparent system of international relations, human rights (as then understood) and for world peace through disarmament and universal collective security rather than traditional approaches such as the balance of power or the creation of power blocs through secret treaties. Chapters of the LNU were set up in the Dominions and in allied nations, including in each of the capital cities of the states of the Commonwealth of Australia.

The headquarters of the LNU were located variously at Buckingham Gate and Grosvenor Crescent, Westminster. In the 1940s they moved to smaller premises in St Martin's Lane, WC2, for reasons of economy. The top organ of administration in the LNU was its General Council. The Council met twice a year and was responsible for LNU policy under its 1925 Royal Charter of Incorporation. Beneath the General Council sat the Executive Committee, which met every two weeks and co-ordinated all activity such as the LNU's campaigns and educational programmes, received reports from branches, monitored the output of specialist sub-groups and had responsibility for the LNU's staff. LNU branches had their own independent management structures.
