The idea of the European Union is based on the European Coal and Steel Community which was established by 6 countries on 18 April 1951. The community aimed to stabilize the continent and reduce disputes by creating economic relationships between partner states. Throughout history its name has changed several times and finally by the Maastricht Treaty in 1993 it took European Union name.
Today, the European Union is more than an economic community that has it’s own norms, laws, currency, and organs. It is a supranational organization. It means that union is superior than member states.
