When spelled as Diocleia or Diokleia, it should not be confused with ancient Phrygian city of Diokleia in Phrygia (Greek: Διόκλεια Φρυγίας).
History
The town was situated ca. 3 km north from present-day Podgorica, Montenegro's capital. The IllyrianDocleatae, which were later Romanized, inhabiting the area derived their name from the city.[3] Doclea was the largest settlement of the Docleatae, and became a municipality during the reign of Emperor Claudius, thus between year 41 and 54 AD.[4] A large town with between 8,000 and 10,000 inhabitants, Doclea had been built to conform to the terrain. The surrounding area had a relatively high population density within a radius of 10 km due to the city's geographical position, a favorable climate, positive economic conditions and defensive site that were of great importance at that time.
Pliny the Elder mentions the cheese of Doclea as a famous Illyrian product.[5]
After the administrative division of the Roman Empire in 297, Doclea became the capital of the new Roman province of Praevalitana, which Roman emperorDiocletian established in the imperial administrative reform of 293, splitting this southern part from the province of Dalmatia. The castle of Doclea was built as a typical Roman castrum with the purpose of controlling the road coming from Dalmatia and going to Scodra.[6]
In the 4th and the 5th centuries, it was taken by the barbarian tribes and went into decline. At the beginning of the 5th century, it was attacked by the Germanic Visigoths. A severe earthquake destroyed it in 518. The South Slavs migrated into the land and proceeded to rebuild the settlement in the 7th century. The historical ruins of the town can be seen today.
Around 877, the synod of Dumno (Delmitanus), elevatated it;, apparently justified as former capital of a Late Roman province Dalmatia Superior, to Metropolitan rank in chief of a Bulgarian ecclesiastical province at the expense of Scutari, but shifting Bulgarian borders made it lose the Metropolitan status again the next century [8]
It was suppressed in 927, when the city was destroyed and its last bishop John took refuge in Ragusa, of which he was soon named Archbishop.
Allegedly from 1034 (no later than the 1062 letter from Pope Alexander II (1061–1073) to their Archbishop Peter) till circa 1100, its now hollow title was nominally united in personal union with the neighbouring, then still Archdiocese of Bar (Antivari), also in modern Montenegro, possibly mainly to justify its (later lost) Metropolitan status.
Few of its bishops are historically documented, and some sources may confound the see with Diocletiana.

Serbian Orthodox titular see
Auxiliary bishops of the Metropolitanate of Montenegro and the Littoral (Serbian Orthodox Church) are given the title "Bishop of Dioclea" (Serbian: епископ диоклијски). Recent holders of the title were bishops Jovan Purić (2004-2011),[11] Kirilo Bojović (2016-2018),[12] and Metodije Ostojić (since 2018).[13]
Roman Catholic titular see
In 1910, the archdiocese was nominally restored as Latin titular archbishopric of the Metropolitan (highest) rank as Dioclea, renamed from 1925 (exclusively from 1933) as Doclea.
It has had the following archiepiscopal incumbents :
Carlo Bertuzzi (Italian) (1910.05.10 – death 1914.01.04), emeritate as former Bishop of Rieti (Italy) (1889.02.11 – 1895.03.18) and Bishop of Foligno (Italy) (1895.03.18 – retired 1910.05.10)
Henri Doulcet (French), Passionists (C.P.) (1914.03.17 – death 1916.07.27) on emeritates, formerly Bishop of Nikopol (Bulgaria) (1895.01.07 – retired 1913.03.31) and Titular Bishop of Ionopolis (1913.06.03 – resigned 1914.03.17)
