The
European Federalist Movement (
Movimento Federalista Europeo, MFE) was founded in Milan in 1943 by a group of activists led by
Altiero Spinelli. The principles which inspired its foundation are contained in the
Ventotene Manifesto, drawn up in 1941 by Spinelli himself, in collaboration with
Ernesto Rossi, Eugenio Colorni and
Ursula Hirschmann. Vayssière notes that the manifesto is widely seen as the birth of European federalism. Spinelli (1907–86), a former Communist, became a leader of the federalist movement due to his primary authorship of the Manifesto and his postwar advocacy. The manifesto called for a break with Europe's past to form a new political system through a restructuring of politics and extensive social reform. It was presented not as an ideal, but as the best option for the Europe's postwar condition.
