The Diocese of Asia or Diocese of Eumenia (Latin: Dioecesis Asiana, Greek: Διοίκησις Ασίας/Ασιανής) was a diocese of the later Roman Empire, incorporating the provinces of western Asia Minor and the islands of the eastern Aegean Sea. The diocese was established after the reforms of Diocletian, was subordinate to the Praetorian prefecture of the East, and was abolished during the reforms of Justinian I in 535.

It was one of the most populous and wealthy dioceses of the Empire, and included 11 provinces:^[1] Asia, Hellespontus, Pamphylia, Caria, Lydia, Lycia, Lycaonia, Pisidia, Phrygia Pacatiana, Phrygia Salutaria and Insulae.

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 After massive territorial losses in the 7th century, the remaining provinces were superseded by the theme system in c. 640–660, although in Asia Minor and parts of Greece they survived under the themes until the early 9th century.
