The European Union has seven main institutions that work together to make laws, manage finances, and ensure the EU runs smoothly. These institutions include the European Parliament, the European Council, the Council of Ministers, the European Commission, the Court of Justice of the European Union, the Court of Auditors, and the European Central Bank. Each institution has specific roles and responsibilities, such as passing laws, interpreting EU law, auditing finances, and managing the euro currency. Additionally, there are agencies that support these institutions in various policy areas.
