# Roman Catholic Diocese of Bobbio

The Roman Catholic diocese of Bobbio was an Italian bishopric which existed from 1014 until 1986. The diocese was formed from the territory of the Abbey of Bobbio.

## History

In the year 1014, the Emperor Henry II, on the occasion of his own coronation in Rome, obtained from Pope Benedict VIII the erection of the Abbey of Bobbio, which was celebrating its 500th anniversary, as an episcopal see. The date of 25 February 1014 is sometimes given for the erection of the diocese, but that is the date of the coronation of the Emperor Henry in Rome. Neither the Emperor's charter nor the Pope's bull, however, survives. The diocese was made a suffragan of the metropolitan of Milan.
The abbot of Bobbio had long been a Count of the Holy Roman Empire in the territory of the Abbey, and he owed feudal dues, including soldiers, when called upon. The abbots continued to hold the title and rank even after the erection of the diocese of Bobbio. In the bishopric of Bishop Luizo, the fourth bishop (c. 1050), the bishop of Bobbio was granted the title of Count for the city of Bobbio.
Pietroaldo, its first bishop, had been Abbot of Bobbio since 999; in contemporary documents he is referred to as abbas et episcopus monasterio sancti Colombani sito Bobio. His episcopal successors for a long time lived in the abbey, where several of them had been monks. The monastery, however, claimed to be directly subject to the Holy See, not to a local bishop, even the Bishop of Bobbio, which produced nearly two centuries of friction and litigation between the Abbey and the Bishop of Bobbio. In 1144 Pope Lucius II granted the monks the right of electing their own abbot. Pope Eugenius III (1145–1153) ruled that the confirmation and blessing of a new abbot, the consecration of altars and churches, and the appointment of monks and clergy, were the right of the bishop of Bobbio and his successors; the decision was confirmed by Pope Lucius III (1181–1185) when further litigation took place. On 28 August 1339, Bishop Calvus de Calvis made a formal visitation to the monastery of S. Colombano, and received the oath of fidelity and obedience from the abbot; he also issued a decree for the reformation of the monastery.
According to Ferdinando Ughelli and others, the diocese Bobbio was made a suffragan see of the Metropolitan Archdiocese of Genoa by Pope Innocent II on 19 March 1133 in the Bull Iustus Dominus. Fedele Savio finds this subordination mentioned for the first time in a Bull of Pope Alexander III, dated 19 April 1161, but in his discussion he remarks that Genoa was only given four suffragans: Mariana, Nebbio and Accia on the island of Corsica, and Brugnato on the mainland. The papal Bull of Innocent II, in fact, names five suffragans, the four just named and a fifth on the mainland, Vobzensem, which is in fact not the name of an actual diocese, but a scribal corruption of Bobiensem, as Ughelli and every other scholar have recognized. The papal Bull of Alexander III, Superna et ineffabilis, addressed to Archbishop Syrus of Genoa, paraphrases the bull of Innocent II, including the phrase in which Bobbio is made a suffragan of Genoa. On 11 May 1219, Bishop Uberto Rocca received Statutes of the Archdiocese of Genoa for promulgation in his diocese.
In 1199 alarming reports reached the ears of Pope Innocent III about the corrupt state of discipline in the monastery of S. Colombano, "that there was hardly a trace of religious feeling in either the abbot or the monks." He issued a mandate to Bishop Oberto of Bobbio on 1 December 1199 to use the power of supervision which had been granted him by the Holy See to visit the monastery, and then send a representative to Rome to report on his findings, so that the Pope could take further measures; he was given until the fourth Sunday in Lent in 1200 to make his report. In the meantime the Pope had entrusted the duty of correcting the monastery to two abbots from Pavia. The abbots were ordered by the Pope to consult with Bishop Oberto.
In 1447 the number of monks remaining in the monastery of S. Colombano di Bobbio had grown so small that Bishop Marciano Baccarini (1447–1463) was compelled to bring Benedictines from the Congregation of S. Justina di Parma to Bobbio to ensure the continuation of the foundation. He also constructed the episcopal palace.
During the occupation of Italy by the armies of the French Republic and then the First Empire, the diocese of Bobbio was suppressed, and its territory reassigned to the diocese of Casale-Monferrato. After the restoration of the Kingdom of Sardinia (Duchy of Savoy), the diocese was restored to its former borders in 1817.
In 1923 it was united with the Territorial Abbey of San Colombano, at Bobbio, from which it originated, with the combined official name diocese of Bobbio-San Colombano. As reorganised in 1986, the territory of the former diocese of Bobbio became part of the Metropolitan Archdiocese of Genova-Bobbio.
In a subsequent change, Bobbio Abbey's 'united title' was transferred, in 1989, to the Metropolitan Diocese of Piacenza-Bobbio, and the territory of the former diocese of Bobbio became part of the diocese of Piacenza.
The Cathedral has a Chapter, composed of two dignities (the Provost and the Archpriest) and ten Canons.
