Praetorian prefecture of Italy

The praetorian prefecture of Italy (Latin: Praefectura praetorio Italiae, in its full form (until 356) praefectura praetorio Italiae, Illyrici et Africae) was one of four praetorian prefectures into which the Late Roman Empire was divided since the first half of the 4th century. It comprised the Italian peninsula, the western Balkans, the upper Danubian provinces and parts of North Africa. The Prefecture's seat moved from Rome to Milan and finally, Ravenna. It existed during the Later Roman Empire, and was part of the Western Roman Empire. The prefecture continued to function within Odoacer's and Ostrogothic kingdoms, and later within the Byzantine Empire, up to 584, when it was reorganized into the Exarchate of Ravenna.

Since most Latin terms and titles had their Greek equivalents, praetorian prefect of Italy was often titled as praetorian eparch of Italy (Greek: πραιτωριανός έπαρχος της Ιταλίας), and the praetorian prefecture itself was designated as praetorian eparchy (Greek: ἐπαρχότης τῶν πραιτωρίων).
