European Economic Community

The European Economic Community (EEC) was a regional organisation created by the Treaty of Rome of 1957, aiming to foster economic integration among its member states. It was subsequently renamed the European Community (EC) upon becoming integrated into the first pillar of the newly formed European Union (EU) in 1993. In the popular language, the singular European Community was sometimes inaccurately used in the wider sense of the plural European Communities, in spite of the latter designation covering all the three constituent entities of the first pillar. The EEC was also known as the European Common Market (ECM) in the English-speaking countries, and sometimes referred to as the European Community even before it was officially renamed as such in 1993. In 2009, the EC formally ceased to exist and its institutions were directly absorbed by the EU. This made the Union the formal successor institution of the Community.

The Community's initial aim was to bring about economic integration, including a common market and customs union, among its six founding members: Belgium, France, Italy, Luxembourg, the Netherlands and West Germany. It gained a common set of institutions along with the European Coal and Steel Community (ECSC) and the European Atomic Energy Community (EURATOM) as one of the European Communities under the 1965 Merger Treaty (Treaty of Brussels). In 1993, a complete single market was achieved, known as the internal market, which allowed for the free movement of goods, capital, services, and people within the EEC. In 1994 the internal market was formalised by the EEA agreement. This agreement also extended the internal market to include most of the member states of the European Free Trade Association, forming the European Economic Area, which encompasses 15 countries.

Upon the entry into force of the Maastricht Treaty in 1993, the EEC was renamed the European Community to reflect that it covered a wider range than economic policy. This was also when the three European Communities, including the EC, were collectively made to constitute the first of the three pillars of the European Union, which the treaty also founded. The EC existed in this form until it was abolished by the 2009 Treaty of Lisbon, which incorporated the EC's institutions into the EU's wider framework and provided that the EU would "replace and succeed the European Community".

In April 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.

With the aim of creating a federal Europe two further communities were proposed: a European Defence Community and a European Political Community. While the treaty for the latter was being drawn up by the Common Assembly, the ECSC parliamentary chamber, the proposed defence community was rejected by the French Parliament. ECSC President Jean Monnet, a leading figure behind the communities, resigned from the High Authority in protest and began work on alternative communities, based on economic integration rather than political integration. Following the Messina Conference in 1955, Paul-Henri Spaak was given the task to prepare a report on the idea of a customs union. The so-called Spaak Report of the Spaak Committee formed the cornerstone of the intergovernmental negotiations at Val Duchesse conference centre in 1956. Together with the Ohlin Report the Spaak Report would provide the basis for the Treaty of Rome.

In 1956, Paul-Henri Spaak led the Intergovernmental Conference on the Common Market and Euratom at the Val Duchesse conference centre, which prepared for the Treaty of Rome in 1957. The conference led to the signature, on 25 March 1957, of the Treaty of Rome establishing a European Economic Community.

The resulting communities were the European Economic Community (EEC) and the European Atomic Energy Community (EURATOM or sometimes EAEC). These were markedly less supranational than the previous communities,^{[citation needed]} due to protests from some countries that their sovereignty was being infringed (however there would still be concerns with the behaviour of the Hallstein Commission). Germany became a founding member of the EEC, and Konrad Adenauer was made leader in a very short time. The first formal meeting of the Hallstein Commission was held on 16 January 1958 at the Château de Val-Duchesse. The EEC (direct ancestor of the modern Community) was to create a customs union while Euratom would promote co-operation in the nuclear power sphere. The EEC rapidly became the most important of these and expanded its activities. The first move towards political developments came at the end of 1959 when the foreign ministers of the six members announced that would be meeting quarterly to discuss political issues and international problems. One of the first important accomplishments of the EEC was the establishment (1962) of common price levels for agricultural products. In 1968, internal tariffs (tariffs on trade between member nations) were removed on certain products.

Another crisis was triggered in regard to proposals for the financing of the Common Agricultural Policy, which came into force in 1962. The transitional period whereby decisions were made by unanimity had come to an end, and majority-voting in the council had taken effect. Then-French President Charles de Gaulle's opposition to supranationalism and fear of the other members challenging the CAP led to an "empty chair policy" whereby French representatives were withdrawn from the European institutions until the French veto was reinstated. Eventually, a compromise was reached with the Luxembourg compromise on 29 January 1966 whereby a gentlemen's agreement permitted members to use a veto on areas of national interest.
