Vlora is one of the oldest cities of Albania. It was founded by Ancient Greeks in the 6th century BC and named Aulōn, one of several colonies on the Illyrian coast, mentioned for the first time by Ptolemy (Geographia, III, xii, 2). Other geographical documents, such as Peutinger's "Tabula" and the "Synecdemus" of Hierocles, also mention it. The city was an important part of the Roman Empire, when it was part of Epirus Nova.
It became an Episcopal see in the 5th century. Among the known bishops are Nazarius, in 458, and Soter, in 553. The diocese at that time belonged to the Patriarchate of Rome. In 733 it was annexed, with all eastern Illyricum, to the Ecumenical Patriarchate of Constantinople, and yet it is not mentioned in anyNotitiae episcopatuum of that Church. The bishopric had probably been suppressed, for, though the Bulgarians had been in possession of this country for some time, Avlona is not mentioned in the "Notitiae episcopatuum" of the Patriarchate of Achrida. Vlorë played a central role in the conflicts between the Norman Kingdom of Sicily and the Byzantine Empire during the 11th and 12th centuries. During the Latin domination a Latin see was established, and Eubel (Hierarchia catholica medii aevi, I, 124) mentions several of its bishops. Several of the Latin bishops mentioned by Le Quien and whomEubel mentions under the Sea of Valanea in Syria, belong either to Aulon in Greece (now Salona) or to Aulon in Albania (Vlorë).
The Serbian Empire captured Vlorë, or Valona, as it was also called, in 1345 and formed the seat of an independent principality until it was captured by the Ottoman Empire in 1417. Under Ottoman rule, it became a sanjak centre in Rumeli Eyaleti as "Avlonya"; and after coming under Venetian possession in 1690, the city was restored to the Turks in 1691, becoming a kaza of the sanjak of Berat in the vilayet (province) of Janina. The city had about 10,000 inhabitants; there was a Catholic parish, which belonged to the
