The European Union is a unique economic and political partnership between 27 European countries that has delivered peace, stability, and prosperity over the past 50 years. It was initially created to foster economic cooperation but has evolved to span all areas of policy. The EU has its own flag, currency (euro), and anthem. It has a bicameral legislative branch consisting of the directly elected European Parliament and the Council of the European Union composed of national ministers. The European Commission acts as the executive branch. The Court of Justice of the European Union interprets EU law.
