The northern Balkans in the 6th century

Dacia Mediterranea (Mediterranean Dacia; Greek: Επαρχία Δακίας Μεσογείου, Eparchia Dakias Mesogeiou) was a late antique Roman province, split off from the former Dacia Aureliana by Roman emperor Diocletian (284-305). Serdica (or Sardica; later Sradetz or Sredets, now Sofia) was the province capital.

Scholars have different opinions regarding the date and circumstances of the foundation of Dacia Mediterranea as a separate province.^[1]

In 535, emperor Justinian I (527-565) created the Archbishopric of Justiniana Prima as a regional primacy with ecclesiastical jurisdiction over all provinces of the Diocese of Dacia, including the province of Dacia Mediterranea'. ^[2]

Late Roman and Byzantine provinces (4th–7th centuries AD)

History

As found in the Notitia Dignitatum. Provincial administration reformed and dioceses established by Diocletian, c. 293. Permanent praetorian prefectures established after the death of Constantine I. Empire permanently partitioned after 395. Exarchates of Ravenna and Africa established after 584. After massive territorial losses in the 7th century, the remaining provinces were superseded by the theme system in c. 640–660, although in Asia Minor and parts of Greece they survived under the themes until the early 9th century.
