The European Union (EU) is a unique political and economic community with supranational and intergovernmental dimensions. It is composed of twenty-seven member states primarily located in Europe. In 1957, six European countries formed the European Economic Community (EEC) by the Treaty of Rome. Since then the EU has grown in size through the accession of new member states and has increased its powers by the addition of new policy areas to its remit. In 1993, the Maastricht Treaty established the base of the current legal framework.
