The European Political Cooperation (EPC) was introduced in 1970 and was the synonym for European Union foreign policy coordination until it was superseded by the Common Foreign and Security Policy in the Maastricht Treaty (November 1993).
In the 1950s and 1960s, the EC member states tried twice to give the internal market a foreign policy dimension but failed on both attempts. The idea of the supranational European Defence Community came about following a summit in The Hague (1969) in which the EC heads of state and government instructed their foreign ministers to "study the best way of achieving progress in the matter of political unification, within the context of enlargement." The foreign ministers subsequently drafted the Luxembourg/Davignon report (1970), which created an informal intergovernmental consultation mechanism where member states could achieve "politics of scale" (Ginsberg, 1989).
While EPC adopted the intergovernmental nature of the Fouchet Plans, it disregarded the 'French grandeur' of the Charles de Gaulle era. The involvement of the United Kingdom guaranteed its Atlanticist nature. The European Commission would furthermore be able to express its opinion if matters within its competencies were concerned. Finally, the EPC did not have the strong Paris-based of the Fouchet proposals. The Netherlands had always been anxious about this idea, as they thought that it might turn into a competitor for the European Commission. The EPC was amended and strengthened in the Copenhagen report (1973) and London report (1981). It was codified (formalized) with the Single European Act (1986).
