when did the eec change to the eu
European Economic Community The European Economic Community (EEC) was a regional organisation which aimed to bring about economic integration among its member states. It was created by the Treaty of Rome of 1957.[1] 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.
