In the late 350s, Constantius II (337–361) expanded the city's Senate and set it as equal to that of Rome. Correspondingly, on 11 September or 11 December 359, Constantinople was also granted an urban prefect, commonly called in English the Eparch from his Greek title (, ho eparchos tēs poleōs). The prefect was one of the emperor's chief lieutenants: like his Roman counterpart, the Constantinopolitan prefect was a member of the highest senatorial class, the illustres, and came immediately after the praetorian prefects in the imperial hierarchy.
