history

The Roman Empire was initially divided into 46 provinces , which Diocletian essentially increased to 101 provinces by dividing around 300 AD, which in turn were combined into dioceses. The head of the dioceses (and provinces) was the vicarius , deputy of the civil officer who emerged from the military praetorian prefect after 312 . Already with the division of the empire in 395 , the structure of the dioceses was changed into four prefectures, 15 dioceses and 119 provinces. The Dioecesis Orientis was outsourced to the Dioecesis Aegypti . The late antique diocesan structure was only abandoned in favor of the thematic constitution in view of the Islamic expansion (from 630) .
