Three pillars of the European Union

Between 1993 and 2009, the European Union (EU) legally comprised three pillars. This structure was introduced with the Treaty of Maastricht on 1 November 1993, and was eventually abandoned on 1 December 2009 upon the entry into force of the Treaty of Lisbon, when the EU obtained a consolidated legal personality.

  1. The European Communities pillar handled economic, social and environmental policies. It comprised the European Community (EC), the European Coal and Steel Community (ECSC, until its expiry in 2002), and the European Atomic Energy Community (EURATOM).
  2. The Common Foreign and Security Policy (CFSP) pillar took care of foreign policy and military matters.
  3. Police and Judicial Co-operation in Criminal Matters (PJCCM) brought together co-operation in the fight against crime. This pillar was originally named Justice and Home Affairs (JHA)
