It was created by the Treaty of Rome of 1957 . Upon the formation of the European Union (EU) in 1993, the EEC was incorporated and renamed as the European Community (EC). In 2009 the EC's institutions were absorbed into the EU's wider framework and the community ceased to exist . </P> <P> 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 covering 15 countries . </P>
