How the EU Governs Europe

01 From Coal to a Continent

The European Union began with coal and steel. In 1951, six nations — Belgium, France, Germany, Italy, Luxembourg, and the Netherlands — signed the Treaty of Paris creating the European Coal and Steel Community. The idea was simple but revolutionary: place the industries that had fueled two world wars under a shared supranational authority, making war between France and Germany materially impossible. Jean Monnet and Robert Schuman, the architects of this arrangement, believed that economic integration would create political interdependence so deep that military conflict would become self-destructive.

The 1957 Treaty of Rome expanded this logic, establishing the European Economic Community and the European Atomic Energy Community. The goal was a common market: free movement of goods, services, capital, and labor across national borders. The Treaty of Rome was less ambitious than some hoped — a political community and a defense community had already failed in the 1950s — but it established the institutional architecture that still governs Europe today.

The Maastricht Treaty of 1993 formally created the European Union, adding foreign policy, justice, and home affairs cooperation to the economic community. It also introduced EU citizenship and laid the groundwork for the single currency. The Lisbon Treaty of 2009 reformed the institutional structure, creating the permanent President of the European Council and the High Representative for Foreign Affairs. What began as a sectoral agreement about coal and steel had become a governing system for nearly 450 million people.

02 The Commission: Europe's Civil Service

The European Commission is the EU's executive arm, but its role is unlike any national government. The Commission has the exclusive right to propose legislation — only it can draft new EU laws. This monopoly on legislative initiative is the most distinctive feature of EU governance. National governments and the Parliament can request legislation, but only the Commission can formally propose it. The Commission also manages the EU budget, enforces EU law, and negotiates trade agreements on behalf of all members.

The Commission is composed of 27 Commissioners — one from each member state — each responsible for a policy area such as agriculture, trade, energy, or competition. The President of the Commission is nominated by the European Council and elected by the European Parliament. The President assigns portfolios and can demand resignations of individual Commissioners. The College of Commissioners operates by consensus and is collectively accountable to the Parliament, which can dismiss the entire Commission with a vote of no confidence.

Beneath the political layer sits the Commission's civil service: approximately 32,000 permanent staff organized into departments called Directorates-General. These civil servants draft policy, conduct impact assessments, and manage programs. The Commission's staff is a fraction of the size of a national civil service, which reflects a structural reality: the EU does not implement most of its own policies. Implementation is delegated to national administrations, with the Commission monitoring compliance and enforcing rules when necessary.

03 The Parliament: The Democratic Arm

The European Parliament is the only EU institution directly elected by citizens. Since 1979, voters across all member states elect Members of the European Parliament every five years. The Parliament has 720 seats distributed among members roughly by population, with smaller countries overrepresented to ensure a voice for every nation. MEPs sit in transnational political groups rather than national delegations — Socialists, Christian Democrats, Liberals, Greens, and others — which is what makes the Parliament genuinely supranational rather than a council of ambassadors.

For decades the Parliament was dismissed as a talking shop with limited power. Successive treaty reforms changed that. Under the Lisbon Treaty, the Parliament is now a co-legislator with the Council of the EU on most policy areas, using the ordinary legislative procedure. The Parliament can amend legislation, reject proposals, and set the EU budget together with the Council. It also elects the Commission President and can dismiss the Commission by a vote of no confidence.

The Parliament's power is greatest in areas where the EU has exclusive competence — the single market, trade, agriculture, and competition policy. In foreign policy, defense, and taxation, where unanimity is required in the Council, the Parliament's role is limited. This asymmetry reflects the tension at the heart of the EU: democratic accountability is strongest where integration is deepest, and weakest where national sovereignty is most jealously guarded.

04 The Council System: Where Sovereignty Lives

Two institutions share the name "Council," which is a persistent source of confusion. The Council of the EU, formerly the Council of Ministers, brings together national ministers from each member state. It meets in different configurations — agriculture, transport, finance, environment — depending on the subject. The Council co-legislates with the Parliament, and on most matters decides by qualified majority voting: at least 55% of member states representing at least 65% of the EU population. This system gives large states more weight while preventing a coalition of a few big countries from dominating.

The European Council is a different body. It comprises the heads of state or government of all member states, plus the Commission President, and meets four times a year for summits. The European Council does not pass laws; it sets the EU's overall political direction and resolves issues that ministers cannot agree on. Its President, elected for a two-and-a-half-year term, facilitates consensus and represents the EU externally at the level of heads of state.

In both councils, unanimity is required for the most sensitive decisions: foreign policy, taxation, social security, and treaty changes. This means a single member state can block action in these areas. The result is a permanent tension between members who want faster integration and those who want to protect national prerogatives. The escape valve is enhanced cooperation, which allows a group of at least nine member states to integrate further in a specific area without waiting for all members to agree.

05 The Court: Making Law Supranational

The European Court of Justice in Luxembourg is the institution that makes EU law truly binding rather than voluntary. The Court rules on whether national laws comply with EU treaties, whether member states have fulfilled their obligations, and whether EU institutions have acted within their powers. Its judgments are binding on member states and EU institutions alike.

The Court's most consequential contribution is the doctrine of direct effect — that EU law creates enforceable rights for individuals in national courts — and the principle of supremacy — that EU law prevails over conflicting national law. These principles were not explicitly written into the founding treaties; the Court established them through a series of landmark rulings in the 1960s. National courts accepted them, integrating EU law into their own legal systems.

The Court includes one judge from each member state, though cases are typically heard by panels of three, five, or fifteen judges rather than the full bench. The Advocate General, a separate office, provides an independent opinion before each ruling, which the Court usually follows. This system ensures legal consistency across 27 national legal traditions, but it also means that the Court's rulings can be politically controversial — as when they have struck down national legislation on immigration, data privacy, or labor rights.

06 The Eurozone and Variable Geometry

Not all EU members use the euro, and not all participate in the Schengen area of passport-free travel. This is called variable geometry: the EU is not a single uniform system but a set of overlapping circles of integration. The eurozone includes 20 of 27 members. Denmark has an opt-out. Sweden has not joined the ERM II exchange rate mechanism. The newest members are expected to adopt the euro once they meet convergence criteria.

The eurozone has its own governance structure. The European Central Bank, based in Frankfurt, sets monetary policy for all eurozone members. The Eurogroup — an informal body of eurozone finance ministers — coordinates fiscal policy. The Stability and Growth Pact sets rules on budget deficits and debt levels, though enforcement has historically been inconsistent. The eurozone crisis of 2010 to 2012 exposed the gap between a shared currency and separate fiscal policies, leading to new institutions: the European Stability Mechanism, the Banking Union, and stronger ECB supervisory powers.

Schengen is equally varied. It includes most EU members plus four non-EU countries: Iceland, Liechtenstein, Norway, and Switzerland. Ireland maintains its own opt-out, while Cyprus has not yet joined. The migration crisis of 2015 tested Schengen, as several members temporarily reinstated border controls. The system survived, but the tension between free internal movement and external border control remains structural.

07 The Democratic Deficit and the Future

The most persistent criticism of EU governance is the "democratic deficit." The Commission, which proposes laws, is not directly elected. The Parliament is elected, but voter turnout has historically been low — often below 50% — and European elections tend to be fought on national rather than European issues. The Council of Ministers operates largely behind closed doors. Decisions that affect 450 million people are made by a complex interplay of institutions that most citizens cannot name.

Supporters argue that the EU's structure provides democratic legitimacy through multiple channels: direct election of the Parliament, national election of the Council members, and the Commission's accountability to the Parliament. The Lisbon Treaty strengthened this by linking the Commission President to the European election results. But the perception that Brussels is distant and unaccountable remains a political force that has driven euroskeptic movements across the continent.

The EU's future will be shaped by the same tension that created it: the need for collective action on issues that no single nation can address — climate, migration, digital regulation, security — versus the desire for democratic control and national identity. The structure that has evolved — supranational institutions balanced by intergovernmental councils, qualified majority voting balanced by unanimity on sensitive matters, a shared court balanced by national courts — is a pragmatic answer to that tension. It is not elegant, but it has kept Europe at peace, prosperous, and governed for over seven decades.
