History
The empire was originally divided into provinciae. In the 290s, Diocletian reorganized the empire into twelve dioceses.
Vicarii were subordinate to the tetrarchs and the corresponding praetorian prefects.
Only the urban provinces of Rome and Constantinople were not placed under a deputy; they were directly ruled by the tetrarchs.
Generally, Gaul and Dacia also did not have deputies because the prefects administered from those Diocese.
