Philip became emperor at the start of 244. (The "Justinianic Code"'s writing means that Philip became emperor after 13 January 244 and before 14 March the same year.) Philip's wife, Marcia Otacilia Severa, became "augusta" (empress) early in 244. After Philip became emperor, the Romans and the Sasanian Empire made peace. With this success, Philip got the name (or ) in the middle of 244. Philip came to Rome in 244, probably in early summer.
