[3] The Carmen Pipinianum (Pippin's Song) is a 9th-century heroic poem, which includes a description of Verona and its churches, and gives a list of the first eight bishops: St. Euprepius, Dimidrianus (Demetrianus), Simplicius, Proculus, Saturninus, Lucilius (Lucillus, Lucius), Gricinus [Wikidata], and Saint Zeno.

Pacificus apparently supported the revolt of Bernardus, son of Pippin, against the Emperor Louis the Pious in 817, and was confined to the monastery of Nonantola for the rest of his life.

By another letter Pope John VIII reminded Adelardus that he had warned him several times through missi and bishops not to harass the monastery.

Pope John then wrote to the clergy of Verona that he had excommunicated Adelardus until he should come to the Papal Court and give adequate explanations for his conduct.

He was searching for heretics in the north, by which he meant those who denied the temporal or spiritual sovereignty of the pope, and was eager for a meeting with the Emperor Frederick I Barbarossa.

The pope arrived in Verona on 22 July 1184, but Frederick was detained in Germany by festivities surrounding the coronation of his son Henry as king.

[21] Finally they held a synod in Verona on 4 November 1184,[22] denouncing various heresies, including the Paterini, the Cathari, the Humiliati of Lyon, the Passagini, the Josephini, and the Arnaldisti (by which he meant the Romans who rejected papal temporal power), and ordering their uprooting.

He chose the name Urban III, and he spent nearly all of his brief pontificate with the Papal Court at Verona, besieged by Frederick with unbelievable fury.

[26] In 1229, the cities of the Marches, as well as Verona, revolted against the authority of Pope Gregory IX in favor of the Emperor Frederick II.

In the summer, Archbishop Philip of Ravenna, who was also papal Legate, and bishop-elect Cossadoca, organized an expedition of Brescians, Modenese, and Veronese exiles, against Ezzolino's force of 300 soldiers, which was in Cremona; they expected to keep it from returning to Verona.

He fell into the hands of the Ghibellines in 1264, and was imprisoned for two years, only being liberated because of the intervention of Pope Clement IV and the King of Aragon.

Clement's death brought on the longest papal vacancy in history, two years and nine months, during which Verona suffered a schism between two would-be bishops.

The news was immediately brought to Avignon to Pope Benedict XII, who promptly excommunicated Mastino and all the people of Verona.

These began with a humiliating procession of the bareheaded Mastino to the cathedral, hearing Mass, and then solemnly begging the Canons to pardon his outrage.

Francesco Condulmer (1439–1453), the nephew of Pope Eugenius IV, founded the college of acolytes to add to the beauty of public worship and to form a learned and pious clergy;[33] the school still exists.

On 23 November 995, a provincial council was held by the Patriarch John of Aquileia to decide the ownership of several churches which were claimed by Bishop Obertus of Verona.

[36] Councils of Verona worthy of note are those of 4 November 1184, at which pope Lucius III presided, in the presence of the Emperor Frederick Barbarossa,[37] and 1276, against the Bogomilian Patarenes, who were somewhat numerous in the Veronese territory, even among the clergy.

Bishop Giovanni Matteo Giberti (1524–1543) held a diocesan synod, the enactments of which were published in 1589, under the direction of Cardinal Augustino Valerio.

The Sons of the Sacred Heart of Jesus,[44] founded on 1 June 1867 by Saint Daniele Comboni, have their mother-house and their college for the Central African missions in Verona.

[45] The violent expansionist military policies of the French Revolutionary Republic brought confusion and dislocation to the Po Valley.

Pope Pius VII, therefore, issued the bull "De Salute Dominici Gregis" on 1 May 1818, embodying the conclusions of arduous negotiations.
