Loris Fortuna (January 22, 1924 – December 5, 1985) was an Italian left-wing politician, and former Member of Parliament since 1963.
Born in Breno, province of Brescia, he was a partisan during World War II, and initially joined the Italian Communist Party (PCI), leaving it in 1956, and crossing the floor to the Italian Socialist Party (PSI), after the anti-Soviet revolts in Hungary were suppressed by the Soviet Red Army. His first ran in elections in 1963; two years later, he promoted, as first signer, the law on divorce, but he then decided not to submit it to the examination on Parliament.
In 1970, however, Fortuna decided to finally present his proposal of law, together with liberal colleague Antonio Baslini, gaining support from the PCI, the Radical Party and the left wing, but opposed by the Christian Democracy. The law, which legalized and regulated divorce in Italy, was then approved on December 1, 1970.
In 1974, Christian Democracy tried to repeal it via a national referendum, but failed, with 59.3% of Italians favourable to maintain the law on divorce. During the referendum campaign, Fortuna bound up with Radical leader Marco Pannella, and then joined his party, but continuing to be member of the Socialist Party.
Subsequently, Fortuna was a strong supporter and promoter also for the law on abortion, which was depenalized in 1978 and survived to another referendum in 1981. He died in Rome, soon after having asked Bettino Craxi for an electoral alliance between the PSI and the Radicals.
