Suffragan diocese in the context of "Roman Catholic Archdiocese of Florence"

Alba Iulia (Romanian pronunciation: [ˌalba ˈjuli.a] ; German: Karlsburg or Carlsburg, formerly Weißenburg [ˈvaɪsn̩bʊʁk] ; Hungarian: Gyulafehérvár [ˈɟulɒfɛɦeːrvaːr]; Latin: Apulum) is a city that serves as the seat of Alba County in the west-central part of Romania. Located on the river Mureș in the historical region of Transylvania, it has a population of 64,227 (as of 2021).

During ancient times, the site was the location of the Roman camp Apulum. Since the High Middle Ages, the city has been the seat of Transylvania's Roman Catholic diocese. Between 1526 and 1570 it was the capital of the Eastern Hungarian Kingdom from which the Principality of Transylvania emerged by the Treaty of Speyer in 1570 and it was the capital of the Principality of Transylvania until 1711. At one point it also was a center of the Eastern Orthodox Metropolitan of Transylvania with suffragan to Vad diocese. On 1 December 1918, the Union of Transylvania with Romania was declared in Alba Iulia, and Romania's King Ferdinand I and, in 1922 Queen Marie were crowned in the Alba Iulia Orthodox Cathedral.

The Eritrean Catholic Church is a sui iuris (autonomous) Eastern Catholic Church based in Eritrea. As a Local Church of the Catholic Church, it is in full communion with the Apostolic See. It was established in 2015 when its territory was separated from the Ethiopian Catholic Church. The Church is organized under a metropolitan bishop who exercises oversight of a number of suffragan dioceses. In its liturgical services, it uses the Alexandrian Rite in the Geʽez language.

Within the Tewahedo tradition, the principal distinction is ecclesial: the Eritrean Catholic Tewahedo Church is in full communion with the Pope of Rome, whereas the Eritrean Orthodox Tewahedo Church is not; both preserve Cyrillian Miaphysitism, the Geʽez Rite, and the historic Tewahedo liturgical-theological heritage.

The Ethiopian Catholic Church is a sui iuris (autonomous) Eastern Catholic church that is based in Ethiopia. As a particular church of the Catholic Church, it is in full communion with the Holy See. Established in 1930, the church is organised under a metropolitan bishop who exercises oversight of a number suffragan dioceses. In its liturgical services, it uses the Alexandrian Rite in the Geʽez language (a local liturgical language).

It holds to the Christological doctrines defined at the Council of Chalcedon and accepts the universal jurisdiction of the pope. These points distinguish it from the Ethiopian Orthodox Tewahedo Church, an Oriental Orthodox church which comprises most Christians in the country.

The following is a list of the Catholic dioceses in Italy. As of May 2017, the Catholic Church in Italy is divided into sixteen ecclesiastical regions. While they are similar to the 20 civil regions of the Italian state, there are some differences. Most ecclesiastical regions are in turn divided into a number of ecclesiastical provinces. The provinces are in turn divided into a number of dioceses. The sovereign state of Vatican City is part of the metropolitan province of Rome. A metropolitan bishop exercises a degree of leadership over a group of dioceses that are loosely subject (suffragan) to the care of the metropolitan see. This list excludes those archdioceses, dioceses and ecclesiastical territories that are immediately subject to the Holy See.

There are 227 sees ('particular churches'), most of which are dioceses led by a bishop. A diocese that is led by an archbishop is known as an archdiocese. There are 40 Metropolitan archdioceses which serve as the seat of an ecclesiastical province. This number includes the Holy See and the Patriarchate of Venice. There are also four archdioceses which are non-metropolitan, having been demoted by papal decree. This brings the number of archbishops in Italy and Vatican City to 44 (i.e. 40 + 4).

A suffragan bishop is a type of bishop in some Christian denominations.

In the Catholic Church, a suffragan bishop leads a diocese within an ecclesiastical province other than the principal diocese, the metropolitan archdiocese; the diocese led by the suffragan is called a suffragan diocese.

It has long maintained its own Latin liturgical rite usage, the Ambrosian rite, which is still used in the greater part of the diocesan territory. Among its past archbishops, the better known are Ambrose, Charles Borromeo, Pope Pius XI and Pope Paul VI.
