The European Union (EU) is a political and economic community of twenty-seven member states, located primarily in Europe. It was created in 1993 by the Treaty of Maastricht, adding new areas of policy to the existing European Community

EU and US Perspectives about China\'s Compliance with Transparency Commitments and the Transitional Review Mechanism. Social Science Research Network. Retrieved on 2007-01-25. In 1999 it introduced a common currency, the euro, which has been adopted by fifteen member states. It has developed a role in foreign policy, representing its members in the World Trade Organization (WTO), at G8 summits and at the United Nations (UN). Twenty-one EU countries are members of NATO. It has developed a role in justice and home affairs, including the abolition of passport control between many member states under the Schengen Agreement.

Much of the EU\'s functioning depends upon agreement between the member states, an intergovernmental feature common to most international organisations.Bundeszentrale für politische Bildung (2006). Lexicon: Internationale Organisationen. Retrieved on 2008-03-06. However, it also has supranational bodies, able to make decisions without the agreement of member states. Important institutions and bodies of the EU include the European Commission, the European Parliament, the Council of the European Union, the European Council, the European Court of Justice and the European Central Bank. EU citizens elect the Parliament every five years.

The EU traces its origins to the European Coal and Steel Community formed among six countries in 1951 and the Treaty of Rome in 1957. 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. The Treaty of Lisbon signed in December 2007 is intended to amend the existing treaties to update the political and legal structure of the union, if ratification is completed in 2008. The EU countries have almost 500million citizens generating an estimated 31% share of the world\'s nominal gross domestic product (GDP) (US$16.6 trillion) in 2007.

History

The political climate after the end of World War II favoured Western European unity, seen by many as an escape from the extreme forms of nationalism which had devastated the continent.The political consequences. European NAvigator. Retrieved on 2007-09-05. One of the first successful proposals for European cooperation came in 1951 with the European Coal and Steel Community. This had the aim of bringing together control of the coal and steel industries of its member states, principally France and West Germany. This was with the aim that war between them would not then be possible, as coal and steel were the principal resources for waging war. The Community\'s founders declared it "a first step in the federation of Europe"", with the hope that this would enable Europe to pursue the development of Africa.Declaration of 9 May 1950.

European Community

Two additional communities were created in 1957: the European Economic Community (EEC) establishing a customs union, and the European Atomic Energy Community (Euratom) for cooperation in developing nuclear energy. In 1967 the Merger Treaty created a single set of institutions for the three communities, which were collectively referred to as the European Communities, although more commonly just as the European Community (EC).Merging the executives.

Maastricht established a revised structure and the name \'European Community\' officially replaced the earlier \'European Communities\'. The European Community now formed one of three pillars of the new European Union, which included co-operation in matters of foreign policy and home affairs. The term European Union generally replaced the term European Community, which will be abolished by the Treaty of Lisbon along with the pillar system.

Austria, Sweden and Finland joined in 1995. The Amsterdam Treaty in 1997 amended the Maastricht treaty in areas such as democracy and foreign policy. Amsterdam was followed by the Treaty of Nice in 2001, which revised the Rome and Maastricht treaties to allow the EU to cope with further enlargement to the east.

At the start of 2007 Romania and Bulgaria joined the EU and the euro was adopted by Slovenia. On 1 January 2008, Malta and Cyprus joined the Eurozone.

A treaty establishing a constitution for the EU was signed in Rome in 2004, intended to replace all previous treaties with a new single document. However, it never completed ratification after rejection by French and Dutch voters in referenda. In 2007, it was agreed to replace that proposal with a new Reform Treaty, that would amend rather than replace the existing treaties. This treaty was signed on 13 December 2007 in Lisbon and is known as the Lisbon treaty. It will come in effect in January 2009 if ratified by that date.

Member states

The European Union is composed of 27 independent sovereign countries which are known as member states: Austria, Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom.European Countries.

To join the EU, a country must meet the Copenhagen criteria, defined at the 1993 Copenhagen European Council. These require a stable democracy which respects human rights and the rule of law; a functioning market economy capable of competition within the EU; and the acceptance of the obligations of membership, including EU law. Evaluation of a country\'s fulfilment of the criteria is the responsibility of the European Council.Accession criteria (Copenhagen criteria). Europa (web portal). Retrieved on 2007-06-26. The current framework does not specify how a country could exit the Union (although Greenland withdrew in 1985), but the proposed Treaty of Lisbon contains a formal procedure for withdrawing.

Geography

Mont Blanc in the Alps is the highest peak in the EU.

The territory of the EU consists of the combined territories of its 27 member states with some exceptions outlined below. The territory of the EU is not the same as that of Europe, as parts of the continent are outside the EU, such as Switzerland, Norway and European Russia. Some parts of member countries are not part of the EU, despite forming part of the European continent (for example the Channel Islands and Faroe Islands). Several territories associated with member states that are outside geographic Europe are also not part of the EU (such as Greenland, Aruba, the Netherlands Antilles and all the non-European territories associated with the United Kingdom). Some overseas territories are part of the EU even if they are not geographically part of Europe, such as the Azores, the Canary Islands, French Guiana, Guadeloupe, Madeira, Martinique, Réunion, Saint Barthélemy and Saint Martin.EUR-Lex: Official Journal.

Nederlanse Administratie Der Belastingen, Eur-Lex (European Court of Justice 1963).. See: Craig and de Búrca, ch. 5. National courts are required to enforce the EU treaties and the laws enacted under them, as membership of the organisation obliges them to do so. In the case of a conflict where a law stemming from EU legislation conflicts with another national law, the EU law is considered to take precedence (principle of \'Supremacy\').According to the principle of Supremacy as established by the ECJ in Case 6/64, Falminio Costa v. ENEL [1964] ECR 585. See Craig and de Búrca, ch. 7. See also: Factortame Ltd. v.

Ministero delle Finanze [1974] 2 CMLR 372; Raoul George Nicolo [1990] 1 CMLR 173. Decisions regarding EU legislation may be referred to the European Court of Justice by national courts. The EU is regulated by a number of institutions, primarily the Council of the European Union, the European Commission, and European Parliament.

The EU is often described as being divided into three areas of responsibility, called "pillars". The original European Community policies form the first pillar, while the second consists of Common Foreign and Security Policy. The third pillar originally consisted of Justice and Home Affairs, however owing to changes introduced by the Amsterdam and Nice treaties, it currently only consists of Police and Judicial Co-operation in Criminal Matters. Broadly speaking, the second and third pillars can be described as the intergovernmental pillars because the supranational institutions of the Commission, Parliament and the Court of Justice play less of a role or none at all, while the lead is taken by the intergovernmental Council of Ministers and the European Council. Most activities of the EU come under the first, Community pillar. This is mostly economically oriented and the supranational institutions have more
