On 7 May 1957, welcoming the signing, on 25 March, in Rome, of the Treaties establishing the European Economic Community (EEC) and the European Atomic Energy Community (EAEC or Euratom), the Action Committee for a United States of Europe (ACUSE) adopts a resolution in which it calls on the governments of the six Member States of the European Coal and Steel Community (ECSC) to ratify as soon as possible the Treaties that they have already signed.
