The New Commonwealth Society was an organization with political aims founded in the United Kingdom in 1932. Its chief aim was the creation of an international air force which would act as a military arm of the League of Nations, promoting disarmament and keeping the world's peace.
Those promoting the New Commonwealth included the millionaire David Davies, 1st Baron Davies, who became its chairman, others who had taken part in building up the League of Nations Union, and Winston Churchill, who was elected as the organization's president. Ernst Jaeckh was appointed as international director.
In a speech to the Society in May 1937, Churchill said
We are one of the few peace societies that advocates the use of force, if possible overwhelming force, to support public international law.
The Society published the New Commonwealth Quarterly to promote its aims. The editorial committee included Otto Neurath. The publication was later succeeded by the London Quarterly of World Affairs.
Some of the ideas of the New Commonwealth Society were later incorporated into the United Nations Charter.
