South Illyria became Epirus Nova, part of the Roman province of Macedonia. In 357 AD the region was part of the Praetorian prefecture of Illyricum one of four large praetorian prefectures into which the Late Roman Empire was divided. By 395 AD dioceses in which the region was divided were the Diocese of Dacia (as Pravealitana), and the Diocese of Macedonia (as Epirus Nova). Most of the region of modern Albania corresponds to the Epirus Nova.
