The Spaak Committee was an Intergovernmental Committee set up by the Foreign Ministers of the six Member States of the European Coal and Steel Community (ECSC) as a result of the Messina Conference of 1955. The Spaak Committee started its work on 9 July 1955 and ended on 20 April 1956, when the Heads of Delegation of the six Member States of the ECSC approved the Spaak report. The committee worked on two main topics, one was the creation of a general common market and the other one was the establishment of a European Community for the peaceful use of atomic energy.
