History of the European Union The report was accepted at the Venice Conference (29 and 30 May 1956) where the decision was taken to organise an Intergovernmental Conference. The Intergovernmental Conference on the Common Market and Euratom focused on economic unity, leading to the Treaties of Rome being signed in 1957 which established the European Economic Community (EEC) and the European Atomic Energy Community (Euratom) among the members. The two new communities were created separately from ECSC, although they shared the same courts and the Common Assembly. The executives of the new communities were called Commissions, as opposed to the "High Authority". The EEC was
European Economic Community and succeed the European Community". The EEC was also known as the Common Market in the English-speaking countries and sometimes referred to as the European Community even before it was officially renamed as such in 1993. In 1951, the Treaty of Paris was signed, creating the European Coal and Steel Community (ECSC). This was an international community based on supranationalism and international law, designed to help the economy of Europe and prevent future war by integrating its members. In the aim of creating a federal Europe two further communities were proposed: a European Defence Community and a European Political Community.
