The Union of Democratic Control was a British pressure group formed in 1914 to press for a more responsive foreign policy.
The impetus for the formation of the UDC was the outbreak of the First World War, which its founders saw as having resulted from largely secret international understandings which were not subject to democratic overview.
Also taking a key role in setting up the Union were politician Arthur Ponsonby, author Norman Angell and journalist E. D.
The UDC criticised the Versailles Treaty as being unjust to Germany, and also advocated the withdrawal of Allied troops from Russia.
Ponsonby also started a petition of those who "refuse to support or render war service to any government which resorts to arms", and in 1928 published Falsehood in War-Time which claimed that public opinion was invariably peaceful unless roused by propaganda.
