Treaty of Nice

26 February 2001

The Treaty of Nice amended the founding treaties of the European Union and was signed by the member states in the French city of Nice, following a difficult summit held there in December 2000. Its main purpose was to prepare the Union for the enlargement that would bring in ten new members in 2004, so it changed voting weights in the Council, extended qualified majority voting, limited the size of the Commission and redistributed seats in the European Parliament. Irish voters rejected the treaty in a referendum in 2001 and approved it in a second vote in 2002, after assurances on Irish neutrality. It entered into force in 2003. Because many thought its reforms inadequate, it led directly to the Convention on the Future of Europe and the proposed European Constitution.
