Archdiocese of Ancona–Osimo
Catholic archdiocese in Italy
The Archdiocese of Ancona–Osimo (Latin: Archidioecesis Anconitana-Auximana) is a Latin Church 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.
