European Union

The European Union is a unique supranational political and economic union of 27 member states, primarily located in Europe. Often described as a sui generis entity, it combines elements of a federation and a confederation, differing from traditional international organizations because its institutions can make decisions that directly affect citizens, businesses, and governments across the continent. With a total area of approximately 4,225,104 square kilometers and a population of just under 452 million as of 2026, the EU represents one of the world's largest economic blocs, generating a nominal GDP of around €18.802 trillion in 2025, roughly one-sixth of global economic output.

The EU operates through a complex institutional framework balancing national and supranational interests. The European Commission, the executive arm, proposes legislation and manages the budget. The European Council, composed of member state leaders, sets the broad political direction. The European Parliament, directly elected every five years, shares legislative power with the Council of the European Union, where national ministers meet by policy area. This structure produces regulations, directives, and policies that touch nearly every aspect of life, from trade and agriculture to digital privacy and climate action.

The EU's de facto capital is Brussels, which hosts the European Commission, European Council, and the Council of the EU. Other institutional seats include Frankfurt (European Central Bank), Luxembourg (Court of Justice and Court of Auditors), and Strasbourg (Parliament's primary seat). The EU maintains a global presence through the European External Action Service, with delegations worldwide, including its office in Washington, D.C., opened in 1952, and a tech-focused office in San Francisco established in 2022. Its official website is europa.eu, and legal documents dating back to 1952 are accessible via EUR-Lex. The EU Open Data Portal provides freely reusable datasets for researchers and the public.

The European Union works for peace, prosperity, and freedom for its citizens in a fairer, safer world. Its core objectives include promoting economic and social progress through the single market and the euro, asserting European values on the global stage, and maintaining freedom, security, and justice without internal borders. The EU also aims to foster sustainable development, combat social exclusion, and protect human rights. The EU's Charter of Fundamental Rights, adopted in 2000, contains 54 articles protecting rights including personal data protection, education, gender equality, artistic expression, scientific research, and worker protections.

The European Union emerged from the ashes of World War II. On 9 May 1950, French Foreign Minister Robert Schuman presented a plan, drafted with Jean Monnet, proposing the integration of the coal and steel industries of Western Europe. This, he argued, would make war between France and Germany not only unthinkable but materially impossible. The Treaty of Paris, signed on 18 April 1951, created the European Coal and Steel Community (ECSC), effective 23 July 1952. The six founding members, Belgium, France, West Germany, Italy, Luxembourg, and the Netherlands, abolished trade barriers on coal and steel by 1953-1954.

Building on this success, the Treaties of Rome were signed on 25 March 1957, establishing the European Economic Community (EEC) and the European Atomic Energy Community (Euratom), both entering into force on 1 January 1958. The European Parliamentary Assembly, forerunner of today's European Parliament, first met on 19 March 1958 in Strasbourg, with Robert Schuman as its President. It renamed itself the European Parliament on 30 March 1962. The Merger Treaty of 1965 unified the executive institutions of the three communities, effective 1967, and the Customs Union was launched in 1968.

The modern European Union was formally established by the Treaty of Maastricht, signed on 7 February 1992 and entering into force on 1 November 1993. The treaty introduced European citizenship, laid the groundwork for a common currency, and established cooperation in foreign policy, justice, and home affairs. The Single European Act of 1986 had already expanded parliamentary powers and created the European Community. The Treaty of Lisbon, effective 1 December 2009, strengthened the European Parliament and created new leadership positions. The EU has since expanded to 27 members, with Croatia joining in 2013. The United Kingdom left in 2020. [edit]
