セウェルス朝
During the Severan dynasty, the position of Praetorian prefect in Italy came increasingly to resemble a general administrative post, and there was a tendency to appoint jurists such as Papinian, who occupied the post from 203 until his elimination and execution at the ascent of Caracalla. Under Severus Alexander the Praetorian prefecture was held by Ulpian until his assassination by the Guard in the presence of the Emperor himself.
