Historical background

The UDC was established during the first days of the First World War to work for parliamentary control of foreign policy and a moderate peace settlement. There was a belief in some quarters that Britain had been dragged into the war because of secret military agreements with France and Russia. The early leaders of the group initially called the Committee of Democratic Control, were Charles Trevelyan (the only member of the Liberal government to resign over the declaration of war), James Ramsay Macdonald, Arthur Ponsonby, Norman Angell and ED Morel. Morel became the secretary and initial driving force behind what was soon re-named the Union of Democratic Control. The group was formally launched with an open letter to the press in early September 1914. The UDC's stated objectives were: parliamentary control over foreign policy and the prevention of secret diplomacy, a movement for international understanding after the war, and a just peace. A Committee of 18 members was established, including Arthur Henderson, JA Hobson and Bertrand Russell. Operations were initially based at Charles Trevelyan's London home, but offices were quickly acquired off the Strand, and later, on Fleet Street. Running costs were met from subscriptions, plus large donations received from several major Quaker business concerns. In late 1917 the UDC reached its maximum membership of some 10,000 individuals in over 100 branches. By 1918, 300 other groups (mainly co-operatives, trade unions and women's organisations) with 650,000 members were also affiliated to the UDC.
