Luxembourg has long been a prominent supporter of European political and economic integration. In efforts foreshadowing European integration, Luxembourg and Belgium in 1921 formed the Belgium-Luxembourg Economic Union (BLEU) to create an inter-exchangeable currency and a common customs regime. Luxembourg is a member of the Benelux Economic Union and was one of the founding members of the European Economic Community (now the European Union). It also participates in the Schengen Group, whose goal is the free movement of citizens among member states. At the same time, the majority of Luxembourgers have consistently believed that European unity makes sense only in the context of a dynamic, transatlantic relationship and as such have traditionally pursued a pro-NATO, pro-U.S. foreign policy.

Luxembourg is the site of the European Court of Justice, the European Court of Auditors, and other vital EU organs. The Secretariat of the European Parliament is located in Luxembourg, but the Parliament usually meets in nearby Strasbourg.
