Question: How long many years had the Italian dictator been in power when he attended the wedding of Giovanna of Italy? Passage:Giovanna married Tsar Boris III of Bulgaria in the Basilica of St Francis of Assisi, Assisi in October 1930, in a Roman Catholic ceremony, attended by Italian dictator Benito Mussolini. Bulgarians deemed her a good match, partly because her mother, Elena of Montenegro, was of Slavic ethnicity. At a second ceremony in Sofia, Giovanna (who herself was daughter of a Roman Catholic father and a formerly Orthodox mother) was married in an Eastern Orthodox Church ceremony, bringing her into conflict with the Roman Catholic Church. Giovanna adopted the Bulgarian version of her name, Ioanna. Giovanna knew the Pope's Apostolic Visitor to Bulgaria, Archbishop Angelo Roncalli, the future Pope John XXIII who was able to help her. She and Boris had two children: Marie Louise of Bulgaria, born in January 1933, and then the future Simeon II of Bulgaria in 1937.
