European Union (EU)

Until November 1993, the EU was known as the European Community (EC). The EU comprises three communities: the European Coal and Steel Community (ECSC), the European Economic Community (EEC), and the European Atomic Energy Community (Euratom). Each community is a legally distinct body, but since 1967 they have shared common governing institutions. The EU forms more than a framework for free trade and economic cooperation: the signatories to the treaties governing the communities have agreed in principle to integrate their economies and ultimately to form a political union. Belgium, France, Italy, Luxembourg, the Netherlands, and the Federal Republic of Germany (West Germany) were charter members of the EU; Britain, Denmark, and Ireland joined on January 1, 1973; Greece became a member on January 1, 1981; and Portugal and Spain entered on January 1, 1986.
