Not to be confused with the European Union, the Western European Union (WEU) is a partially dormant European defence and security organization composed of those states members of both NATO and the EU.

The WEU was established on October 23, 1954, as part of a modified version of the Brussels Treaty , in response to the failure of the European Defence Community treaty. Most of its functions are in the process of being merged into the European Union. The Parliamentary Assembly of the WEU is composed of the delegations of the member states to the Parliamentary Assembly of the Council of Europe, which, fearful for its future existence with the winding up of the WEU, has been lobbying for itself to be recognised as the "European Security and Defence Assembly".

Some of the moves that have taken place and indicate the partial merger of the WEU into the Common Foreign and Security Policy of the EU have been the following:

• On November 20, 1999, Javier Solana, who is the High Representative for the Common Foreign and Security Policy of the EU, was also appointed Secretary-General of the WEU. His being head of both organisations permits him to oversee the ongoing transfer of functions from the WEU to the EU.
• The so-called Petersberg tasks, declared by the WEU in 1992, were incorporated in 1997 into the treaty of Amsterdam of the EU, forming the basis of the European Security and Defence Policy which frames a common security and defence policy to deal with humanitarian and rescue tasks, peacekeeping tasks and tasks of combat forces in crisis management, including peacemaking.
• The European Union Institute for Security Studies (EUISS) and European Union Satellite Centre (EUSC), both established to function under the EU's Common Foreign and Security Policy pillar, are replacements to the Western European Union Institute for Security Studies and the Western Union Satellite Centre which had been established to function in connection to the WEU.

Supposedly full merger was to occur in the year 2000; however, as of 2004 the WEU is however still alive and much European military planning takes place within its constituent cells. Indeed New York University's book, Defending Europe, paints the situation as a "revival of WEU" rather than a shutting down of same.
