A guide to the institutional changes to the European Union brought about by the ratification of the Treaty of Nice.

The Nice treaty was adopted on 10 December 2000 by the fifteen Heads of State and Government at the end of the French Presidency of the European Union. The Treaty is the cornerstone of an EU enlargement process which is unprecedented in the history of European construction and which will put an end to several decades of painful division. This title, a follow-up to the Rome, Maastricht and Amsterdam Treaties - Comparative Texts, published in 1999, highlights the amendments and new Articles contained in the Nice Treaty compared with its precursors.
