Treaty of Maastricht

The Maastricht Treaty served two purposes. It amended the provisions of the Treaty of Rome while significantly advancing the agenda set out under the Single European Act (SEA) in 1986, for deepening European Political Union (EPU). It created a new model for the Community based around three ‘pillars’ which, broadly speaking, covered economic relations, foreign affairs and home affairs. It also officially created the European Union (EU), which became the title to cover all the functions of the much-expanded European governmental structure. In addition, it began the process of Economic and Monetary Union (EMU), which would lead to the creation of the Euro. Coming at a time of political upheaval in Britain and across Europe, the Treaty was hugely controversial and has come to be seen as a central moment in the movement towards deeper European integration.


Negotiations for the new treaty began through two separate Inter-governmental Conferences (IGCs) – one dealing with Monetary Union, the other with Political Union. In April 1991, a draft set of treaties was presented at the Luxembourg European Council, after which extensive negotiations were took place between national governments, leading to the signing of the Treaty in the Dutch town of Maastricht on 7 February 1992. However, this was far from the end of the story. In June 1992, the Danish people rejected the treaty in a referendum. Subsequently, the British Government narrowly won a vote on the treaty in the House of Commons, which forced Prime Minister John Major to postpone final ratification of the Treaty until after a second Danish referendum in 1993. Although the British Government then ratified the treaty, the controversy that surrounded it provided a huge boost to those sceptical about the European project.

What did the Maastricht Treaty do?

The Treaty pushed forward two broad processes – the widening of EU responsibilities and the deepening of integration. This meant using supranational structures in some areas while using intergovernmental ones in others. In order to make EMU possible it amended the original Treaty of Rome, reinforcing the economic responsibilities of the European Community in line with the goals of the SEA. At the same time, however, it set up a whole new range of intergovernmental responsibilities outside the remit of the Treaty of Rome in the areas of a common foreign policy and home affairs. Institutionally, it transformed the way in which the organisation was structured. While the Commission retained responsibility for the economic ‘pillar’ of EU activity, the new ‘pillars’ were to be controlled not by the Commission but by the European Council. However, the three separate pillars would all be linked under the overarching structure of the European Union.

The Treaty also attempted to strengthen the EU Parliament’s power, by introducing theco-decision procedure. Lastly, a Social Chapter covering employment and social issues was not included in the Treaty itself, but was annexed to the treaty as a protocol, although the UK decided to opt-out of its provisions.



  • The Maastricht Treaty created a structure capable of coping with closer integration and Monetary Union while giving national governments more say through an expanded European Council.
  • The process of closer integration through Monetary Union made it vital to have closer political co-operation.
  • The British Government succeeded in including the principle of subsidiarity in the Treaty, which helped counter-balance the federalist tendencies of other parts of the document. This has since gained great importance.


  • The deepening measures of the Treaty pushed forward a federalist model of European integration that set the Community in the direction of a United Europe.
  • The focus on big issues like EMU distracted people from the expansion of EU control over other areas such as environment, security and foreign affairs.

The European Union Treaty… within a few years will lead to the creation of what the founding fathers of modern Europe dreamed of after the war, the United States of Europe.” – Helmut Kohl, German Chancellor, 1992.
