The Federal Union of European Nationalities (FUEN) is an international non-governmental organization (NGO) established in 1949 in conjunction with the formation of the Council of Europe. FUEN is an umbrella organization, and as of 2023, it has more than 100 member organizations representing ethnic, linguistic and national minorities within Europe. FUEN has been instrumental in encouraging the Council of Europe to adopt the European Charter for Regional or Minority Languages and the Framework Convention for the Protection of National Minorities. FUEN was organized to give expression to European cultures and languages that do not possess form as a nation-state. One in seven Europeans are members of such minorities and fifty-three languages are spoken in Europe by such minorities.[1]
Its predecessor was the pre-war European Congress of Nations (German: Europäischer Nationalitätenkongress) founded by Ewald Ammende. The Congress published a journal "Nation und Staat" (1927–1944).
FUEN organises the Europeada association football tournament.[2] In 2017-2018, FUEN collected 1,124,322 signatures from EU citizens for the Minority SafePack European Citizens' Initiative.
It is based in Flensburg, Germany, with offices in Berlin and Brussels. Its president is Lóránt Vincze, Hungarian from Romania and MEP.[3]
