Archdiocese of Dioclea

Doclea (also Dioclea or Diocleia) was a Roman city, the seat (but not permanently exclusively) of the Late Roman province of Praevalitana, and Metropolitan Archbishopric, which is now a Latin Catholic titular see.

The town was situated ca. 3 km north from present-day Podgorica, Montenegro's capital. The Romanized Illyrian tribe known as Docleatae that inhabited the area derived their name from the city. It was the largest settlement of the Docleatae, founded in the first decade of the 1st century AD. Doclea was built to conform to the terrain. It was a large town with 8–10,000 inhabitants. 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.

After the administrative division of the Roman Empire in 297, Doclea became the capital of the new Roman province of Praevalitana, which Roman emperor Diocletian established in the imperial administrative reform of 293, splitting this southern part from the province of Dalmatia.

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 proceeded to rebuild the settlement in the 7th century. The historical ruins of the town can be seen today.

Circa 400, the city became the seat of a bishopric, initially as suffragan of the Archdiocese of Salona . A letter from Pope Gregory I to bishop Constanti(n?)us (circa 602) suggests it had become suffragan of the Archdiocese of Scutari.
