The European Union (EU) is a political and economic union consisting of 27 member states, primarily located in Europe. Established through the Maastricht Treaty in 1993, the European Union has its roots in earlier institutions such as the European Economic Community, created in 1957. The union operates through a hybrid system of supranational and intergovernmental decision-making, with key institutions including the European Commission, the European Parliament, and the European Council. Its primary objectives include promoting economic integration, maintaining peace and stability, ensuring the free movement of goods, services, people, and capital, and establishing common policies on trade, agriculture, and regional development. The EU also issues a common currency, the euro, used by 20 of its member states in the eurozone. Over the years, the union has expanded both geographically and in terms of its competencies, influencing global trade, environmental standards, and diplomatic relations. Challenges such as Brexit, migration crises, and debates over @sovereignty continue to shape its evolution and policies.
