EU is a political and economic union of 27 European sovereign states created to foster integration after World War II. Originating from postwar arrangements such as the Treaty of Paris (1951) and the Treaty of Rome (1957), it has developed supranational institutions including the European Commission, the European Parliament, and the Court of Justice of the European Union to coordinate policies across areas such as trade, competition, and regional development. The union operates a single market and a customs union, with a shared currency used by a subset of members, and engages in external affairs through instruments like the European External Action Service.
Origins trace to the Schuman Declaration and the creation of the European Coal and Steel Community alongside postwar recovery mechanisms such as the Marshall Plan. The Treaty of Rome (1957) established the European Economic Community and the European Atomic Energy Community, fostering common policies and the gradual elimination of barriers among founding states including France, West Germany, Italy, Belgium, Netherlands, and Luxembourg. Subsequent milestones include the Single European Act (1986), the Treaty of Maastricht (1992), which created the union and a roadmap to the euro, and the Treaty of Lisbon (2007), which reformed institutional structures after enlargements that admitted countries from Southern Europe and later from Central Europe and the Baltic states. Crises such as the 2008 financial crisis, the Greek government-debt crisis, and the United Kingdom European Union membership referendum, 2016 culminating in Brexit reshaped political dynamics and integration debates.
Key bodies include the European Commission as executive and supranational initiator of legislation, the Council of the European Union representing member state governments, and the directly elected European Parliament sharing legislative power via the Ordinary legislative procedure. Judicial oversight is provided by the Court of Justice of the European Union and the European Court of Auditors audits finances. The European Central Bank manages monetary policy for the eurozone members alongside national central banks such as the Bundesbank and Banque de France. Political leadership positions created or adapted by treaties include the President of the European Council and the High Representative of the Union for Foreign Affairs and Security Policy, supported administratively by the European External Action Service.
Membership began with six founding states and expanded via waves: the United Kingdom and Ireland with Denmark in 1973, Greece in 1981, Spain and Portugal in 1986, the post-Cold War enlargement of 2004 admitting ten states including Poland, Czech Republic, Hungary, and Estonia, and later accessions such as Romania and Bulgaria. The Treaty of Accession 2003 framework and the Copenhagen criteria guide candidates like Turkey, North Macedonia, and Albania through chapters of negotiation. Enlargement interacts with instruments such as the Stabilisation and Association Process for the Western Balkans and accession procedures governed by member states and institutions like the European Council.
Primary law derives from treaties such as the Treaty on European Union and the Treaty on the Functioning of the European Union, supplemented by secondary legislation: regulations, directives, and decisions. Competition policy enforced by the European Commission addresses state aid and antitrust issues in cases involving firms like Microsoft and Apple; trade policy is conducted with partners under frameworks like the World Trade Organization and bilateral agreements such as the European Economic Area and the EU–Canada Comprehensive Economic and Trade Agreement. Social and regional cohesion is advanced via funds implemented under programming periods, and regulatory harmonization occurs in sectors impacted by rulings from the Court of Justice of the European Union.
The single market enables free movement of goods, services, capital, and persons among member states, combined with a customs union and common external tariffs. The euro is legal tender for eurozone countries; monetary policy is set by the European Central Bank while fiscal rules are coordinated under the Stability and Growth Pact and mechanisms such as the European Stability Mechanism address sovereign debt crises like those experienced by Greece and Portugal. Economic governance includes initiatives like the European Semester and investment programs such as the Investment Plan for Europe to promote growth and competitiveness amid challenges including digital transformation and demographic change.
External action is coordinated through the European External Action Service and the High Representative who combine diplomatic, development, and security tools. The union undertakes common foreign and security policy tasks including missions under the Common Security and Defence Policy, naval operations like Operation Atalanta, and sanctions regimes against actors such as Russia following the 2014 annexation of Crimea and the 2022 invasion of Ukraine. The EU engages in neighborhood policy via the Eastern Partnership and strategic partnerships with actors like the United States, China, and African Union while cooperating with NATO on defence and crisis management.
Citizenship rights established by the Treaty of Maastricht grant mobility and electoral rights in local and European elections for nationals of member states; programs like Erasmus promote academic exchange among universities including Sorbonne University and University of Warsaw. Cultural initiatives involve the Creative Europe program and designations like European Capital of Culture for cities such as Istanbul (candidacy) and Liverpool (2008).
