This Very Short Introduction explains the European Union in plain English. Fully updated for 2007 to include controversial and current topics such as the Euro currency, the EU´s enlargement, and its role in ongoing world affairs, this accessible guide shows how and why the EU has developed from 1950 to the present. Covering a range of topics from the Union´s early history and the ongoing interplay between ´eurosceptics´ and federalists, to the single market, agriculture, and the environment, the authors examine the successes and failures of the EU, and explain the choices that lie ahead in the 21st century.
