The Flag of EuropeThe European Union (EU) is an economic and political union of 28 member states. The EU has developed a single market through new laws that apply to all member states. Passport controls have been abolished in what is known as the Schengen Area, which includes most—but not all—of the EU member states. The EU's aims include ensuring the free movement of people, goods and services. There are common policies on trade, agriculture and fisheries. A monetary union, known as the Eurozone, in which the euro is the currency used in all countries that are members (18 out of 28), was established in 1999.
Origins of the EU
The EU’s origins were in the European Coal and Steel Community (ECSC). After World War II ended, France and Germany came up with a plan to ensure they would never again go to war with one other. So they, plus four other nations—Italy, Belgium, Netherlands and Luxemburg—agreed to pool their coal and steel resources. Then, following the signing of the Treaty of Rome in 1957, the same six countries formed the European Economic Community (EEC) or Common Market, which came into being in 1958. Since then, a number of other European states have joined, including Britain. The Maastricht Treaty established the European Union under its current name in 1993. Today the EU has 28 member states with a total population of more than 500 million.
