The Diocese of Imola () is a Latin Church diocese of the Catholic Church in Romagna, northern Italy. It is a suffragan of the Archdiocese of Bologna."Diocese of Imola" Catholic-Hierarchy.org. David M. Cheney. Retrieved February 29, 2016."Diocese of Imola" GCatholic.org. Gabriel Chow. Retrieved February 29, 2016. The diocese had originally been a suffragan of the metropolitan of Milan, and was then subject to the Archbishop of Ravenna until 1582, when Pope Gregory XIII made Bologna an archbishopric and assigned it two suffragans, Imola and Cervia. In 1604, however, Pope Clement VIII returned them to the metropolitanate of Ravenna.Kehr, Italia pontificia V, p. 162. Pope Pius VII transferred Imola back to the metropolitanate of Bologna.

The diocese of Imola is noted for having had a number of its bishops elected to the Papacy, including Cardinal Fabio Chigi (1652), afterwards Pope Alexander VII; Cardinal Barnaba Chiaramonti (1785), afterwards Pope Pius VII; and Cardinal Giovanni Maria Mastai Ferretti (1832), afterwards Pope Pius IX.

History

The Christian origins of Imola are obscure. The episcopal see certainly antedates St. Ambrose, who, during a vacancy in the diocese of Imola, asked the bishop of Voghenza (the ancient Vicus Haventia), to visit the church of Imola, until a bishop was consecrated, since Ambrose himself was occupied and unable to carry out a visitation.Lanzoni, pp. 774-775. Ambrose was concerned about the Gothic Arians and the inroads that their heresies were making on the orthodox Christians.Ambrose, Epistulae VII. 1: Commendo tibi, fili, Eccclesiam quae est ad Forum Cornelii, quo eam de proximo intervisas frequentius, donec ei ordinetur episcopus. Occupatus diebus ingruentibus quadragesimae, tam longe non possum excurrere. Habes illic Illyrios de mala doctrina Arrianorum. Cave eorum zizania, non appropinquens fidelibus, non serpant adulterina femina. Advertant quid propter suam perfidiam accident sibi, quiescant, aut veram fidem sequantur.

In 435 Emperor Valentinian III built the church of S. Maria in Arenula. The bishop then was Cornelius, whose archdeacon Peter was appointed Bishop of Ravenna by Pope Sixtus III. Bishop Peter, known as Chrysologus, gave a magnificent eulogy of Bishop Cornelius at the consecration of his successor, Projectus.Chrysologus himself was buried at Imola, having died in his native city. His tombstone, discovered in 1698, was a rude block on which was written PETRUS. Of the gifts said to have been given by Chrysologus to the church of Imola there is still preserved a paten, with the figure of a lamb on an altar, surrounded by the metrical legend Quem plebs tunc cara crucis agnum fixit in ara. Hostia fit gentis primi pro labe parentis. These leonine verses, however, indicate a much more recent date, and refute the pious tale of the donation.

In 888, Pope Stephen V ordered the Archbishop of Ravenna to see to it that a bishop was canonically elected for Imola. There was to be no election while the incumbent was still alive, even though he might be ill. When there was a legitimate vacancy, the Clergy was to carry out the election, and the People were to approve it. There had earlier been strife in the city when the People attempted to elect a bishop without reference to the Clergy. It was only later that the Cathedral Chapter began to exercise the rights which had once belonged to the entire Clergy.Zaccaria, I, p. 105. Kehr, p. 163. By the year 1217, the right to elect the bishop belonged to the Canons of the Cathedral of S. Cassiano and the Canons of San Lorenzo, acting as a single electoral college.Zaccaria, p. 105.

On 7 August 1118, Pope Gelasius II restored to the Archbishop of Ravenna all of the dioceses which had been removed from his metropolitanate by Pope Paschal II, due to the participation of the archbishops in the schism that supported the Emperor Henry IV. One of the dioceses that was restored to Ravenna was the diocese of Imola.P. Jaffé and S. Loewenfeld, Regesta pontificum romanorum I, second edition (Leipzig 1885), p. 777, no. 6647. Zaccaria, pp. 107-108.

Other bishops are: John (946), who restored the cathedral and embellished the tomb of St. Peter Chrysologus; Ridolfo (1146) and Enrico (1174), who suffered for their adherence to Pope Alexander III, Enrico laid the foundations of the present cathedral, finished in 1271 under Bishop Sinibaldo; Pietro Ondedei (1416), a distinguished canonist and theologian; the Dominican Gaspare Sighigelli (1450), learned and saintly; Girolamo Dandini (1546), formerly nuncio at Paris, founder of an orphan asylum; Francesco Guarini (1566), the founder of the seminary; Cardinal Filippo Antonio Gualterio (1702), founder of a mone frumentario to supply the poor peasant with seed; and Cardinal Giovanni Carlo Bandi (1752), who rebuilt the cathedral and the basilica of Valentinian.

French occupation The Battle of Lodi was fought on 10 May 1796, giving the general of the army of the French Republic, Napoleon Bonaparte, a claim to having routed Austrian forces. The claim was actually established after he won the Battle of Mantua, the battle at the Arcola, and the Battle of Rivoli. On 27 June an armistice was arranged between Napoleon and the papal armies of Pope Pius VI, in which the Pope lost control of the March of Ferrara and Bologna. On 1 February 1797 the city of Imola was occupied by the French. The Bishop of Imola, Cardinal Chiaramonti, was ordered by the Pope not to fall into the hands of the French, and therefore he fled from Imola to Cesena, intending to head for Rome. At Spoleto, however, he received a plea from the French magistrates and Bonapartists in Imola to return, but after writing to the Pope, who pointed out that Chiaramonti had no way of controlling them, he continued on his journey to Rome. In fear of being supplanted on his episcopal throne by some French-sponsored intruder, he obtained papal permission to return.Zaccaria, pp. 235-236.

On 17 February 1797, Napoleon and papal representatives signed the Treaty of Tolentino, in which the Pope surrendered Avignon, the Comtat Venaissin, and the Romagna. Imola was incorporated into the short lived Cispadane Republic (16 October 1796 – 9 July 1797). On 18 October 1797 Bonaparte entered into the Treaty of Campo Formio with the Austrians, promising them in secret clauses the Republic of Venice; he was able to withdraw to Paris, and then set off on his eastern expedition. In his Christmas message of 1797, therefore, Cardinal Chiaramonti faced impossible difficulties in attempting to calm the Imolese and to suggest a way through the political situation. He wrote. The French army which was left behind, led by General Berthier, occupied Rome on 10 February 1798, and arrested the Pope on 20 February. Pius VI was deported to Siena and then to Florence.

The Austrians took the opportunity of Bonaparte's absence from Italy to advance into territory which Bonaparte had seized, and on 30 June 1799 Imola was occupied by the Austrians.

Pope Pius VI died on 29 August 1799, in the fortress of Valence, a prisoner of the French Directory. The Conclave to elect his successor took some time to find a secure place to hold its meetings. The pope and cardinals had been expelled from Rome in 1798, and there were few places where the cardinals could assemble without fear of French interference. They chose Venice, which was under the "protection" of the Austrians. The Conclave opened on 30 November 1799, and on 14 March 1800 Cardinal Chiaramonti, Bishop of Imola, was elected pope. He chose the name Pius VII. He did not, however, relinquish the diocese of Imola, retaining it until his return from his imprisonment in France (1808–1814) by the Emperor Napoleon. In the Consistory of 8 March 1816, Pius resigned the diocese of Imola into the hands of Cardinal Antonio Rusconi.Gaetano Moroni, Dizionario di erudizione storico-ecclesiastica Vol. XXXIV (Venezia: Tipografia Emiliana 1845), p. 109 column 1. Alberghetti, p. 178. Zaccaria, pp. 237-239. J.P. Adams, Sede Vacante 1799–1800; retrieved: 15 August 2018.

After the Battle of Marengo on 14 June 1800, Imola again found itself under French occupation and incorporated into the Cisalpine Republic, and then into Napoleon's Kingdom of Italy (1805–1814).Cerchiari, pp. 87, 89, 94-95

On 16 September 1803, Pius VII (Chiaramonti) entered into a Concordat with the Praeses reipublicae Italicae, primus Gallicanae reipublicae Consul (Napoleon Bonaparte), which included provisions for redrawing the map of the ecclesiastical provinces of northern Italy. In Article II, Imola, Reggio, Modena, and Carpi were assigned as suffragans of the diocese of Bologna.

Cathedral and Chapter The Cathedral of Imola is dedicated to the memory of the martyr Cassianus of Imola. Cassiano was not a bishop of Imola.Lanzoni, p. 774. The cathedral was served by a Chapter of Canons, headed by seven dignities. The dignities were: the Provost, the Archdeacon, the Archpriest, the Dean, the Primicerius, the Thesaurius, and the Custos. There were eleven Canons, each with a prebend.Ughelli, Italia sacra II, p. 622. The number was fixed by Bishop Mainardinus Aldigieri in 1230: esse debeat numerus undecim Canonicorum tantum sine preposito. Zaccaria, I, pp. 116-117. In 1751, there were eight dignities and twelve Canons.Ritzler-Sefrin, Hierarchia catholica VI, p. 243 note 1.

The bishops of Imola enjoyed the right to appoint, confirm, enthrone, and invest the Canons of the Cathedral Chapter, the Provosts, and the other prelates. The Bishop and Canons together elected the Sacristan, but the bishop alone confirms and invests.Zaccaria, II, pp. 70-71 (document from the last decade of the 12th century).

The Provost and Canons are mentioned as parties to a lawsuit in a mandate of Pope Urban III (1185–1187).Kehr, p. 165 no. 2. Zaccaria, I, p. 116, gives the wrong date of 1124, by confusing Pope Celestine III with Pope Celestine II. In 1511, Pope Julius II secularized the Provostship, and reserved the appointment to the Holy See. His first appointment was Giovanni Battista Vulpi, a Protonotary Apostolic and brother of the soldier Taddeo Vulpi. The dignity of Primicerius was created in 1504 by Bishop Simone Bonadies (1488–1511). The dignity of Treasurer was created in 1513, and was under the patronage of the Saxatelli family, and then the Machirelli. The dignity of Custos was instituted in 1526.Zaccaria, I, pp. 119-120. It was Bishop Alessandro Musotti (1579–1607) who instituted the Canon Penitentiarius and the Canon Theologus out of the eleven Canons, in accordance with the decree of the Council of Trent.Zaccaria, I, p. 120.

In the 12th century, the Canons lived in Castro S. Cassiani, in a building called the Canonica, which was near enough to the Episcopal Palace that the bishop could observe visually the comings and goings of the Canons. Not all of the Canons resided in the Canonica, however; some are recorded from time to time as living in the Guest House (Xenodochium) of the Monastery of S. Vitale, which belonged to the Canons. In the second half of the 12th century, under Bishops Rodulphus (1147–1168), Arardus, and Henricus (1173–1193), when the Castro S. Cassiani was in ruins, they moved to the village of Duccia.There was a castle (castrum) in Duccia, and a church dedicated to S. Maria de Castro. Zaccaria, I, p. 129. Then Bishop Henricus built them a new house in Imola itself, to which the Canons moved in 1188.Zaccaria, I, pp. 121-122. Sometimes a Canon was Abbot of the monastery of S. Vitale.

After his return to Rome from a year-long visit to Imola (having been driven out of his native Florence), Cardinal Niccolò Ridolfi, the Apostolic Administrator of Imola (1533–1546), sent the diocese a set of Constitutions for the Canons of the Cathedral.Alberghetti, Parte seconda, p. 153.
