Archdiocese of Bari-Bitonto

The Archdiocese of Bari-Bitonto (Latin: Archidioecesis Barensis-Bituntina) is Metropolitan Latin archdiocese of the Catholic Church in the administrative Bari province, Puglia (Apulia) region, southeastern Italy (the 'Heel'), created in 1986, when the historical diocese of Bitonto was subsumed in the Archdiocese of Bari.

The first known bishop of Bari was said to have been Gervasius, or Gerontius, who, in 347, was present at the Council of Sardica. Gerontius, however, was actually from the city of Beroea in Macedonia, and there is no record of Gervasius, or of Bari, at the Council of Sardica.

In 530 bishop Peter is said to have held the title of Metropolitan under Epiphanius, bishop of Constantinople & Ecumenical Patriarch, though there is no reliable record of this. In the 6th century the bishops of Apulia were directly subject to the Roman pontiff. It was not until after the Byzantine Patriarchs regained their control of Calabria and Apulia after the decree of Leo I that Bari became an archbishopric, and that situation changed when the Normans invaded Calabria and Apulia in the 11th century and returned the Churches of Calabria and Apulia to the Roman obedience.

In 780 bishop Leontius was present at the Second Council of Nicaea.

In the ninth century the Saracens laid waste Apulia, destroyed the city of Canosa (Canusium) and captured Bari. In 841, however, the Byzantine army reconquered Bari, and in 844 Bishop Angelarius, Bishop of Canosa, brought to Bari the relics of Rufinus, Memorus, and Sabinus of Canosa, which he had rescued from the ruins of Canosa. Pope Sergius II conferred on Angelarius the title of Bishop of the two dioceses of Bari and Canosa, a title which the archbishops of Bari retained up to 1986. In 988 the Saracens descended upon Bari, depopulated the countryside and took men and women to Sicily as captives. In 991 Count Atto fought against the Saracens at Taranto, where he and many men of Bari fell. In 1002 Bari was besieged from 2 May until October, when they were rescued by Pietro Orseolo (II), the Doge of Venice.

In 933 Pope John XI granted the bishops of Bari the use of the pallium. It seems that the bishops were dependent on the Eastern Ecumenical Patriarch until the 10th century. Archbishop Giovanni II (952) was able to withdraw from this influence, refusing to accept the prescriptions of the patriarch concerning liturgical points. All connection with the Eastern Churches was finally severed during the eleventh century, as Bari became a direct ecclesiastical dependency of Rome. So before the 10th c was over, the top ranking Orthodox episcopal dignitary throughout Byzantine Italy, became the archbishop of Melfi, in spite of Bari remaining the center of Byzantine authority in the area, as the seat of the katepano of Italia until the capture of the city by the Normans in 1071.

Ironically the archbishop of Bari that irreversibly distanced his see from Byzantium, was Byzantius (1025), who obtained from the pope the privilege of consecrating his suffragans.^{[citation needed]} He also began the construction of the new cathedral, which was continued by his successors, Nicolo (1035), Andreas (1062), and Elias (1089) of the Benedictine Order.

By contrast to Bishop Byzantius' Catholicism affections, Andreas, the archbishop from 1062 to at least 1066, kept an eye to the roots of his Faith, for example journeying to Constantinople, and at some point even converting to Judaism. Archbishop Andreas then fled to Muslim-dominated Egypt, where he eventually died in 1078. Remarkably, the next archbishop Urso (1080–1089) was captured by the Muslim forces and converted to Islam.
