The enlargement of the European Union involves the accession of new
member states. This process began with the
Inner Six, who founded the
European Coal and Steel Community (the EU's predecessor) in 1952. Since then, the EU's membership has grown to twenty-seven with the most recent expansion to
Croatia in 2013 and the departure of UK in 2020. Currently, accession negotiations are under way with several states. The process of enlargement is sometimes referred to as
European integration. This term is also used to refer to the intensification of co-operation between EU member states as national governments allow for the gradual harmonisation of national laws. To join the European Union, a state needs to fulfil economic and political conditions called the
Copenhagen criteria (after the
Copenhagen summit in June 1993), which require a stable democratic government that respects the rule of law, and its corresponding freedoms and institutions. According to the
Maastricht Treaty, each current member state and the
European Parliament must agree to any enlargement. The present enlargement agenda of the European Union regards
Ukraine, the
Western Balkans and potentially Turkey, which has a long-standing application with the EU. As for the Western Balkan states, the EU had pledged to include them after their
civil wars: in fact, two states have entered, three are candidates, one applied and the others have pre-accession agreements. There are however other states in Europe which either seek membership or could potentially apply if their present foreign policy changes, or the EU gives a signal that they might now be included on the enlargement agenda. However, these are not formally part of the current agenda, which is already delayed due to bilateral disputes in the Balkans and difficulty in fully implementing the
acquis communautaire (the accepted body of EU law). Today the accession process follows a series of formal steps, from a pre-accession agreement to the ratification of the final accession treaty. These steps are primarily presided over by the European Commission (
Enlargement Commissioner and
DG Enlargement), but the actual negotiations are technically conducted between the Union's Member States and the candidate country. Before a country applies for membership it typically signs an
association agreement to help prepare the country for candidacy and eventual membership. Most countries do not meet the criteria to even begin negotiations before they apply, so they need many years to prepare for the process. An association agreement helps prepare for this first step. In the case of the
Western Balkans, a special process, the
Stabilisation and Association Process exists to deal with the special circumstances there. When a country formally applies for membership, the Council asks the commission to prepare an opinion on the country's readiness to begin negotiations. The council can then either accept or reject the commission's opinion (the council has only once rejected the commission's opinion when the latter advised against opening negotiations with Greece). If the council agrees to open negotiations the screening process then begins. The commission and candidate country examine its laws and those of the EU and determine what differences exist. The Council then recommends opening negotiations on "chapters" of law that it feels there is sufficient common ground to have constructive negotiations. Negotiations are typically a matter of the candidate country convincing the EU that its laws and administrative capacity are sufficient to execute European law, which can be implemented as seen fit by the member states. Often this will involve time-lines before the
Acquis Communautaire (European regulations,
directives and standards) has to be fully implemented. == Gallery of EU candidate state passports ==
