Macedonia

The Diocese of Macedonia (Latin: Dioecesis Macedoniae, Greek: Διοίκησις Μακεδονίας) was a diocese of the later Roman Empire, forming part of the praetorian prefecture of Illyricum. Its administrative centre was Thessaloniki.

The diocese was formed, probably under Constantine I (r. 306–337), from the division of the Diocletianian Diocese of Moesia. It included the provinces of Macedonia Prima, Macedonia Secunda or Salutaris (periodically abolished), Thessalia, Epirus vetus, Epirus nova, Achaea, and Crete. Alongside Dacia and, up until 379, Pannonia, it made up the Prefecture of Illyricum. In 379, Pannonia was detached and merged into the Praetorian prefecture of Italy and Thessaloniki became the Prefecture's new capital city instead of Sirmium.

Joseph Roisman, Ian Worthington, A Companion to Ancient Macedonia,

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 After massive territorial losses in the 7th century, the remaining provinces were superseded by the theme system in c. 640–660, although in Asia Minor and parts of Greece they survived under the themes until the early 9th century.
