Luxembourg has long been a prominent supporter of European political and economic integration. In 1921, Luxembourg and Belgium formed the Belgium–Luxembourg Economic Union (BLEU) to create a regime of inter-exchangeable currency and a common customs. 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 (named after the Luxembourg village of Schengen where the agreements were signed). 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 thus have traditionally pursued a pro-NATO, pro-US foreign policy.
