The Merger is the very first reform that brought together the European Community. It was signed by the Luxembourg Prime Minister in Brussels on 8 April 1965. Others who were present during the signing of the Merger were Pierre Werner, Albert Borschette who accompanied the Prime Minister and Luxembourg Permanent Representative to the European Communities. It brought together as one all the Executives of the European Coal and Steel Community, the European Economic Community and also the European Atomic Energy Community.
Before the Merger was signed, the European Community comprised of six member states which included; France, Italy, West Germany, Belgium, Luxembourg and the Netherlands. During that time, all the communities each had their own Councils of Ministers. The signing of the Merger was an agreement among the member states that they would hence forth have a common European court of Justice and that they would also share the Parliamentary Assembly. The original idea was to also create an intergovernmental set up which would allow foreign policy cooperation among all the members. This policy was to monitor all the activities of the members. Not much is said in history books about the Merger which was later on overtaken by several other treaties between the member states.
