In June 1989, Italian citizens had the opportunity to express their opinion about whether the European Parliament (EP) should draw up a constitution for an European Union. This referendum is the starting point and focus of the engagement with Italy´s view on the question of Europe. The «historic» event is hardly ever mentioned in general historical accounts; in non-Italian scholarship, it has gone almost completely unnoticed. The present study aims to counteract this. It distinguishes between two different histories leading up to the referendum: an immediate history that begins in 1979 with the first direct elections for the EP or in 1984 with the adoption of a draft constitution at the end of term of the first EP; and a longer history that begins in 1941 in the middle of the war with the Ventotene Manifesto or in 1945. The excurses into these two pasts are followed by a brief look at what has happened since the referendum.
