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.
