European Union

[ben3011]

The European Union (EU) is a sui generis union, made up of twenty-seven European countries. It was established as the European Economic Community in 1957 by the Treaty of Rome and has undergone many changes since, most notably in 1992 by the Maastricht Treaty. Since 1957 new accessions have raised the number of member states, and powers have expanded. As a result, the EU can be described as both a supranational and an intergovernmental body.
