The European Union (EU) is a political and economic union of 27 member states located primarily in Europe. It has an estimated population of about 447 million people and operates through a system of supranational institutions and intergovernmental negotiations among the member states. The EU has developed an internal single market through a standardized system of laws that apply in all member states. The policies aim to ensure the free movement of people, goods, services, and capital within the internal market.
History
The European Union's foundations lie in the aftermath of World War II, with the goal of fostering economic cooperation and preventing future conflicts. The first steps towards European integration began with the establishment of the European Coal and Steel Community (ECSC) in 1951 and the European Economic Community (EEC) in 1957, created by the Treaty of Rome. The Maastricht Treaty, signed in 1992, marked the formal creation of the European Union and introduced new forms of cooperation between the member states in areas such as defense, justice, and home affairs.
Institutions
The EU's institutional framework consists of several key bodies:
- European Commission: The executive arm responsible for proposing legislation, implementing decisions, and managing the day-to-day operations of the EU.
- European Parliament: The directly elected parliamentary institution that represents EU citizens and exercises legislative functions alongside the Council of the European Union.
- Council of the European Union: Also known as the Council of Ministers, it represents the governments of the member states and, together with the European Parliament, forms the legislative branch of the EU.
- European Council: Consists of the heads of state or government of the member states, along with the President of the European Council and the President of the European Commission. It sets the EU's overall political direction and priorities.
- Court of Justice of the European Union (CJEU): Ensures the uniform application and interpretation of European law and resolves disputes between EU institutions and member states.
- European Central Bank (ECB): Manages the euro and formulates monetary policy within the Eurozone, which comprises 19 of the 27 EU member states.
Member States
As of 2024, the EU consists of 27 member states, following the departure of the United Kingdom in 2020. Member states are committed to the EU's foundational principles, including democracy, rule of law, and respect for human rights.
Policies and Initiatives
The EU has a wide range of policies and initiatives, including:
- Single Market: Ensures the free movement of goods, services, people, and capital.
- Customs Union: Applies a common external tariff to all goods entering the market.
- Common Agricultural Policy (CAP): Supports farmers and promotes sustainable agriculture within the EU.
- Cohesion Policy: Aims to reduce disparities between various regions of the EU.
- Environmental Policy: Focuses on sustainability and combating climate change, including the European Green Deal initiative.

Economic and Monetary Union
The Economic and Monetary Union (EMU) represents a significant integration step, involving the coordination of economic and fiscal policies, a common monetary policy, and a common currency, the euro, used by 19 member states.
Enlargement
The EU has undergone several enlargements, growing from the initial six founding members to the current 27. Enlargement is a complex process that requires candidate countries to meet specific criteria, including stable institutions guaranteeing democracy, the rule of law, and the adoption of EU laws and regulations.
Challenges
The EU faces various challenges, including economic disparities among member states, migration, geopolitical tensions, and the rise of Euroscepticism. The COVID-19 pandemic and Brexit have also posed significant challenges to EU unity and its operational framework.
Global Role
The EU plays a crucial role in global affairs through its common foreign and security policy. It is the largest trading bloc in the world and a significant contributor to international development aid. The EU also engages in diplomatic efforts, conflict resolution, and the promotion of human rights globally.
