Investopedia explains 'European Union - EU'
The current formalized incarnation of the European Union was created in 1993 with 12 initial members. Since then, many additional countries have since joined. The EU has become one of the largest producers in the world, in terms of GDP, and the euro has maintained a competitive value against the U.S. dollar.
EU and non-EU members must agree to many legal requirements in order to trade with the EU member states.
