Roman Catholic Archdiocese of Ancona–Osimo
The Archdiocese of Ancona–Osimo () is a joint ecclesiastical territory and metropolitan see of the Catholic Church in the Marche region of Italy. It has existed in its present form since 1986, when the Archdiocese of Ancona was united with the historical Diocese of Osimo. Since earliest times, the diocese has been directly subject to the Holy See without intermediate authorities. The archbishop has his episcopal throne in the Cathedral of Ancona, while the Cathedral of Osimo has the status of a co-cathedral. In the 17th, 18th, and 19th centuries, the archbishop of  Ancona was frequently a cardinal. One, Prospero Lambertini, became Pope Benedict XIV. History. On 19 October 1422, by virtue of the bull "Ex supernae majestatis", Pope Martin V decreed the union of the diocese of Ancona and the diocese of Numana (Humana, Umana). Except for the title, the diocese of Numana was completely suppressed. On 14 September 1904, the Consistorial Congregation of the Papal Curia issued a decree, which had been approved by Pope Pius X, elevating the diocese of Ancona-Numantia to the rank of archiepiscopal see, without any suffragans and with the status and geographical definition of the  diocese unchanged. The decree also granted the archbishops the use of the "pallium" and the archiepiscopal cross, but only within the confines of their own diocese. Cardinal Achille Manara was continued as head of the archdiocese, now as archbishop. On 15 August 1972, by the bull "Qui apostolico officio", Pope Paul VI created the new ecclesiastical province of Ancona, and granted its archbishop the status of Metropolitan. The ecclesiastical province was assigned the suffragan dioceses of Jesi (Aesina) and Osimo (Auximana). On 5 July 1975, having obtained the permission of Pope Paul VI, the Congregation of Bishops ordered that the  title of the archdiocese should only be the Archdiocese of Ancona. The title of Numana was reserved, to become a titular bishopric. The diocese of Ancona was united to the diocese of Osimo by a decree of the Congregation of Bishops on 30 September 1986. Its name was to be "Archidioecesis Anconitana-Auximana". The seat of the diocese was to be in Ancona. The former cathedral in Osimo was to have the honorary title of co-cathedral, and its chapter was to be the Capitulum Concathedralis. There was to be only one episcopal curia, one seminary, one ecclesiastical tribunal; and  all the clergy were to be incardinated in the diocese of Ancona–Osimo. Cathedral and chapter. The cathedral of Ancona suffered considerable damage in World War I, when the Austrian navy bombarded the port of Ancona in May 1915. In 816, the Emperor Louis the Pious held a council at Aix, at which it was ordered that Canons and Canonesses live together according to a set of rules (canons, "regulae"). In the Roman synod of Pope Eugene II of November 826, it was ordered that Canons live together in a cloister next to the church. In 876, the Council of  Pavia decreed in Canon X that the bishops should enclose the Canons: "uti episcopi in civitatibus suis proximum ecclesiae claustrum instituant, in quo ipsi cum clero secundum canonicam regulam Deo militent, et sacerdotes suos ad hoc constringant, ut ecclesiam non relinquant et alibi habitare praesumant." The earliest history of the Chapter of S. Cyriaco is without documentation. In 1179, however, Pope Alexander III issued a bull, confirming the Archdeacon and his colleagues in the Chapter all the rights, privileges and property which they possessed. In the bull he mentions their right to offerings made at certain altars in the cathedral , which had been granted by Bishops Transbertus, Marcellinus and Bernardus. The Chapter was therefore in existence by the very end of the 11th century. Bishop Gerardus fixed the maximum number of Canons in the cathedral Chapter at twelve. He then obtained a bull from Pope Honorius III in 1224 which confirmed his action. From early times there were three dignities: the Archdeacon, the Archpriest, and the Primicerius. In 1622, the Chapter of the Cathedral of S. Cyriaco was composed of two dignities and twelve Canons. In 1710, in addition to the twelve Canons, there were four dignities: these included the  Primicerius, the Archdeacon, and the Archpriest. In 1746, there were three dignities. The Collegiate Church of S. Maria della Piazza in Ancona was also served by a Chapter, composed of a Provost and six Canons. Synods. A diocesan synod was an irregularly held, but important, meeting of the bishop of a diocese and his clergy. Its purpose was (1) to proclaim generally the various decrees already issued by the bishop; (2) to discuss and ratify measures on which the bishop chose to consult with his clergy; (3) to publish statutes and decrees of the diocesan synod, of the provincial synod , and of the Holy See. Bishop Luigi Galli (1622–1657) presided over a diocesan synod in Ancona in 1654. A diocesan synod was held by Cardinal Giannicolò Conti (1666–1698) on 4–5 November 1674. Cardinal Marcello d'Aste (1700–1709) held a diocesan synod in Ancona in 1708; its Constitutions were published in 1738. Cardinal Giovanni Battista Bussi (1710–1726) presided over a diocesan synod in the cathedral at Ancona on 15–18 September 1726. Cardinal Bartolomeo Massei (1731–1745) held a diocesan synod in the cathedral of S. Cyriaco on 26–28 October 1738. Cardinal Giovanni Ottavio Bufalini (1766–1782) held a diocesan synod on 1–3 September 1779 . On 13–15 November 1883, Cardinal Achille Manara held a diocesan synod in the cathedral of Ancona.
