The Supreme Economic Council was established at the Paris Peace Conference in February 1919 to advise the conference on economic measures to be taken pending the negotiation of peace. Specialized commissions were appointed to study particular problems: the organization of a League of Nations and the drafting of its Covenant; and the determination of responsibility for the war and guarantees.
