The European Union (EU) stands as a distinctive political and economic union composed of 27 member states located primarily in Europe. Operating as a supranational entity, it covers a vast geographic area and generates a massive nominal gross domestic product, positioning itself as a central pillar of the global economy and international diplomacy.
Its foundational framework rests on a customs union and an internal single market that ensures the free movement of people, goods, services, and capital across participating borders. Through standardized legislation, common trade policies, and integrated judicial frameworks, member states act collectively on numerous international fronts.
