Signed in Brussels on 8 April 1965 by the foreign ministers of the six founding member states and in force from 1 July 1967, the Merger Treaty combined the separate councils and separate commissions of the European Coal and Steel Community, the European Atomic Energy Community and the European Economic Community into a single Council and a single Commission, while leaving the three Communities themselves legally distinct. This single Council is the direct predecessor of today's Council of the European Union.
