Although the drafts of both the Maastricht treaty and the Treaty establishing a Constitution for Europe mentioned federalism, the representatives of the member countries (all of whom would have had to agree to use of the term) never formally adopted it. The strongest advocates of European federalism have been Germany, Italy, Belgium and Luxembourg while those historically most strongly opposed have been the United Kingdom, Denmark and France (with conservative presidents and governments). Since the presidency of François Mitterrand (1981-1995), the French authorities have adopted a much more pro-European Unification position, as they consider that a strong EU is presenting the best "insurance" against a unified Germany which might become too strong and thus a threat for its neighbours.
