European Union

The European Union is a politico-economic regional grouping of 28 European states. The EU operates through a system of supranational institutions and intergovernmental-negotiated decisions by the member states. 
== History ==
=== European Economic Community ===
In 1957, Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany signed the Treaty of Rome, which created the European Economic Community (EEC) and established a customs union. They also signed another pact creating the European Atomic Energy Community (Euratom) for co-operation in developing nuclear energy. Both treaties came into force in 1958. Through the 1960s, tensions began to show, with France seeking to limit supranational power. Nevertheless, in 1965 an agreement was reached and on 1 July 1967 the Merger Treaty created a single set of institutions for the three communities, which were collectively referred to as the European Communities. Jean Rey presided over the first merged Commission. In 1973, the Communities enlarged to include Denmark (including Greenland, which later left the Community in 1985, following a dispute over fishing rights), Ireland, and the United Kingdom. Norway had negotiated to join at the same time, but Norwegian voters rejected membership in a referendum. In 1979, the first direct, democratic elections to the European Parliament were held.
Greece joined in 1981; Portugal and Spain in 1986. In 1985, the Schengen Agreement led the way toward the creation of open borders without passport controls between most member states and some non-member states. In 1986, the European flag began to be used by the Community and the Single European Act was signed.
In 1990, after the fall of the Eastern Bloc, the former East Germany became part of the Community as part of a reunited Germany. With further enlargement planned for former communist states, Cyprus, and Malta, the Copenhagen criteria for candidate members to join the EU were agreed upon in June 1993.
=== Expansion ===
The European Union was formally established when the Maastricht Treaty—whose main architects were Helmut Kohl and François Mitterrand—came into force on 1 November 1993. The treaty also gave the name European community to the EEC, even if it was referred as such before the treaty. In 1995, Austria, Finland, and Sweden joined the EU. In 2004, the EU saw its biggest enlargement to date when Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia joined the Union.
On 1 January 2007, Romania and Bulgaria became EU members. On 1 December 2009, the Lisbon Treaty entered into force and reformed many aspects of the EU. In particular, it changed the legal structure of the European Union, merging the EU three pillars system into a single legal entity provisioned with a legal personality, created a permanent President of the European Council, the first of which was Herman Van Rompuy, and strengthened the High Representative, Catherine Ashton. 
== Politics ==
The EU operates within those competencies conferred on it by the treaties and according to the principle of subsidiarity (which dictates that action by the EU should only be taken where an objective cannot be sufficiently achieved by the member states alone). Laws made by the EU institutions are passed in a variety of forms. Generally speaking, they can be classified into two groups: those which come into force without the necessity for national implementation measures and those which specifically require national implementation measures. 
=== Governance ===
The European Union has seven institutions: the European Parliament, the Council of the European Union, the European Commission, the European Council, the European Central Bank, the Court of Justice of the European Union and the European Court of Auditors. Competencies in scrutinising and amending legislation are divided between the European Parliament and the Council of the European Union while executive tasks are carried out by the European Commission and in a limited capacity by the European Council (not to be confused with the aforementioned Council of the European Union). The interpretation and the application of EU law and the treaties are ensured by the Court of Justice of the European Union. The EU budget is scrutinised by the European Court of Auditors. There are also a number of ancillary bodies which advise the EU or operate in a specific area.
 European Council 
The European Council gives direction to the EU, and convenes at least four times a year. It comprises the President of the European Council, the President of the European Commission and one representative per member state; either its head of state or head of government. The European Council has been described by some as the Union's "supreme political authority". The European Council uses its leadership role to sort out disputes between member states and the institutions, and to resolve political crises and disagreements over controversial issues and policies.
 European Commission 
The European Commission acts as the EU's executive arm and is responsible for initiating legislation and the day-to-day running of the EU. The Commission is also seen as the motor of European integration. It operates as a cabinet government, with 28 Commissioners for different areas of policy, one from each member state, though Commissioners are bound to represent the interests of the EU as a whole rather than their home state.
 European Parliament 
The European Parliament forms one half of the EU's legislature (the other half is the Council of the European Union). The 751 Members of the European Parliament (MEPs) are directly elected by EU citizens every five years on the basis of proportional representation. Although MEPs are elected on a national basis, they sit according to political groups rather than their nationality. Each country has a set number of seats and is divided into sub-national constituencies where this does not affect the proportional nature of the voting system. 
 Council of the European Union 
The Council of the European Union forms the other half of the EU's legislature. It consists of a government minister from each member state and meets in different compositions depending on the policy area being addressed. Notwithstanding its different configurations, it is considered to be one single body. In addition to its legislative functions, the Council also exercises executive functions in relations to the Common Foreign and Security Policy.

=== Monetary Union ===
The creation of a European single currency became an official objective of the European Economic Community in 1969. In 1992, after having negotiated the structure and procedures of a currency union, the member states signed the Maastricht Treaty and were legally bound to fulfill the agreed-on rules including the convergence criteria if they wanted to join the monetary union. In 1999 the currency union started, first as an accounting currency with eleven member states joining. In 2002, the currency was fully put into place, when euro notes and coins were issued and national currencies began to phase out in the eurozone, which by then consisted of 12 member states. In 2025, France, Greece, Ireland, Spain and Portugal withdrew from the eurozone, with Italy withdrawing in 2026, leaving 15 countries, led by Germany, remaining in the currency.
The euro, and the monetary policies of those who have adopted it in agreement with the EU, are under the control of the European Central Bank (ECB). The ECB is the central bank for the eurozone, and thus controls monetary policy in that area with an agenda to maintain price stability. It is at the centre of the European System of Central Banks, which comprehends all EU national central banks and is controlled by its General Council, consisting of the President of the ECB, who is appointed by the European Council, the Vice-President of the ECB, and the governors of the national central banks of all 28 EU member states. 
The European System of Financial Supervision is an institutional architecture of the EU's framework of financial supervision composed by three authorities: the European Banking Authority, the European Insurance and Occupational Pensions Authority and the European Securities and Markets Authority. To complement this framework, there is also a European Systemic Risk Board under the responsibility of the ECB. The aim of this financial control system is to ensure the economic stability of the EU.
