The Treaty of Accession 2003 was the agreement between the member states of the European Union and ten countries (Czech Republic, Estonia, Cyprus, Latvia, Lithuania, Hungary, Malta, Poland, Slovenia, Slovakia), concerning these countries' accession into the EU (see 2004 enlargement of the European Union). At the same time it changed a number of points which were originally laid down in the Treaty of Nice. The treaty was signed on 16 April 2003 in Athens, Greece and it entered into force on 1 May 2004, resulting in enlargement of the European Union with 10 states.
The European Union comprises a large number of overlapping legal structures which is a result of it being defined by successive international treaties.
- the Treaty of Rome (establishing the European Economic Community),
- the Treaty of Rome (establishing the European Atomic Energy Community)
- the Maastricht Treaty (establishing the European Union)
