General Information

The European Union (EU)--not to be confused with the Council of Europe--is a treaty-created body of western European countries. It started in 1951 and, as of April 2007, includes twenty-five member states.

The primary objectives of the European Union are:

  • to promote economic and social progress (the single market was established in 1993; the single currency was launched in 1999)
  • to assert the identity of the European Union on the international scene (through European humanitarian aid to non-EU countries; common foreign and security policy; action in international crises; and common positions within international organizations)
  • to introduce European citizenship (which does not replace national citizenship but complements it and confers a number of civil and politic rights on European citizens)
  • to develop an area of freedom, security, and justice (linked to the operation of the internal market and more particularly the freedom of movement of persons)
  • to maintain and build on established EU law (all the legislation adopted by the European institutions, together with the founding treaties). (Source)
