The European Union is a political and economic union of 27 European countries that are located mainly in Europe. It was established in the aftermath of World War II to promote peace, stability, and economic prosperity among its member states. The EU operates through a system of supranational institutions and intergovernmental decisions made by member countries. It has its own currency (the euro) and policies on a wide range of issues, including trade, competition, environmental protection, and human rights.
