before his election as bishop; there he remained until the death of the intruder Bonactus, in 1164 or 1165. The schismatic Pope Victor IV died on 20 April 1164, and his schismatic successor Guido Cremensis (Antipope Paschal III) died on 20 September 1168. Their successor, Joannes de Struma (Calixtus III), surrendered to the real Pope, Alexander III, on 29 August 1178. The remnants of the schism were liquidated at the Third Council of the Lateran in March 1179, by which time Bishop Theobaldus had died. Suffragan From time immemorial, the bishops of Gubbio had been directly subordinate (suffragans) of the Holy See (Papacy), with no supervisory archbishop intervening, and were therefore required to attend Roman synods. But in 1563 the situation was altered. In his bull Super universas of 4 June 1563, Pope Pius IV reorganized the administration of the territories of the March of Ancona by creating a new archbishopric by elevating the bishop and Archdiocese of Urbino. He created the new ecclesiastical province of Urbino, which was to include the dioceses of Cagli, Pesaro, Fossombrone, Montefeltro, Senigallia. and Gubbio.

In the 15th century, the dukedoms of Montefeltro and Urbino fell into the hands of the della Rovere family. But the family did not prosper, in terms of male heirs. In 1623, the aged duke, Francesco Maria II lost his only son to an epileptic seizure. Without suitable collateral relatives, he determined to leave his dukedoms to the Papacy, and, on 30 April 1624, the appropriate documents were registered in Rome. Taddeo Barberini, the nephew of Pope Urban VIII, took formal possession and appointed a governor, though Duke Francesco Maria continued to rule during his lifetime. When he died on 23 April 1631, Urbino, and Gubbio along with it, was incorporated into the Papal States. In accordance with the decree Christus Dominus, chapter 40, of the Second Vatican Council, on 15 August 1972 Pope Paul VI issued the decree Animorum utilitate, in which he changed the status of the diocese of Perugia, from being directly dependent upon the Holy See to being a Metropolitan archdiocese. The ecclesiastical province of Perugia was to contain as suffragans the dioceses of Assisi, Citta di Castello, Citta della Pieve, Foligno, Nocera and Tadinum, and Gubbio. The diocese
