Valentinian dynasty

The Valentinian Dynasty or Valentinianic Dynasty, consisting of four emperors, ruled the Western Roman Empire from 364 to 392 and the Eastern Roman Empire from 364 to 378.

The dynasty was related to the Theodosian dynasty by the marriage of Theodosius I of the East to Valentinian I's daughter. From this marriage came Galla Placidia, whose son Valentinian III became the western emperor (425–455), the last ruler descended from either dynasty. His descendants continued to be a part of the Roman nobility in Constantinople until the end of the 6th century.
