The diocese of Cagli e Pergola was a Roman Catholic ecclesiastical territory in the Marche, central Italy, in the province of Pesaro and Urbino.
The cathedral was staffed and administered by a corporation called the Chapter, consisting of two dignities (the Provost, and the Archdeacon) and eleven canons, one of whom was the Theologus (preacher).
[11] His successor on 8 March 1503, a Spanish Dominican, Ludovico de Lagoria, who was a promoter of Borgia's outrages, was nearly killed by the people of Cagli during his first entry into the city.
To restore order, Pope Julius II transferred Langoria to the diocese of Lavelli in the Kingdom of Naples on 23 February 1504.
[12] On 4 June 1563, Pope Pius IV signed the bull "Super Universas", by which he elevated the diocese of Urbino to the status of metropolitan archdiocese.
[14] Bishop Lodovico Agostino Bertozzi (1754-1802) wrote a detailed letter to Cardinal Leonardo Antonelli, the Prefect of the Congregation of the Propaganda of the Faith and Protector of the diocese of Cagli, revealing the extent of the catastrophe.
[15] Pope Pius VI responded with generous funds, allowing not only for the rebuilding of the cathedral and much of the city, but also for the foundation of useful institutions, a hospital for the sick and an orphanage for poor girls.
When they arrived at Cagli, the Vicar General Cingari in a kindly spirit welcomed the commander and accompanied him to the episcopal palace to meet the ninety-four year old Bishop Bertozzi.
Bishop Bertozzi had asked the pope several times to accept his resignation on grounds of ill health and great age, but the presence of the French made it inadvisable.
[18] Circumstances in Rome were not so favorable, and on 15 February 1798, the French general Louis Berthier proclaimed the Roman Republic and deposed the pope.
[22] In February 1808, Napoleon, Emperor of the French, occupied the Papal States, and, on 17 May 1809, annexed them to metropolitan France, creating new "departements," Tibère and Toscane.
[29] Pope Pius VII, who excommunicated Napoleon on 11 June 1809 in the bull "Quum memoranda", was arrested by the French on 5 July 1809 and deported to Savona.
[30] Pius refused thereafter to perform any papal acts whatever, and the bishops nominated by Napoleon never received canonical approval or installation.
Having consulted with the prelates concerned and with members of the College of Cardinals, Pius VII issued the bull "Romani pontifices" on 31 January 1818, granting all the jurisdictions in the territory of Pergola to the diocese of Cagli.
[22] On 18 January 1819, Pope Pius VII issued the bull "Commissa tenuitati", by which he raised the territory of Pergola to the status of a diocese, which was permanently attached, aeque personaliter, to the bishop of Cagli.
[40] The establishment of a seminary for training priests was ordered, in accordance with the decrees of the Council of Trent; initially it was to be housed in the former convent of the Canons Regular at S. Andrea, along with the bishop's residence, and the diocesan offices.
[42] A project begun on orders from Pope John XXIII, and continued under his successors, was intended to reduce the number of dioceses in Italy and to rationalize their borders in terms of modern population changes and shortages of clergy.
