The Valentinian Dynasty, consisting of four emperors, ruled the West Roman Empire from 364 to 392 and the East Roman Empire from 364 to 378. The western emperors were Valentinian I (364-375) and his sons Gratian (375-383) and Valentinian II (375-392); the eastern emperor was Valentinian I's brother Valens (364-378). The dynasty was related to the House of Theodosius by the marriage of Theodosius I of the East (379-395) to Valentinian I's daughter. From this marriage came Galla Placidia, whose son Valentinian III became the western emperor (425-455), though he was technically neither of the Valentinian nor the Theodosian house. Although Valentinian III was 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 sixth century.

Valentinian was aware that the empire was too large and dangerous to govern alone.
As Western Roman Emperor, Valentinian took Italy, Illyrium, Spain, Gaul, Britain and Africa, leaving to Eastern Roman Emperor Valens the eastern half of the Balkan peninsula, Greece, Egypt, Syria and Asia Minor as far east as Persia.
Valentinian’s two sons and Valens' nephews, Gratian and Valentinian II were evelated to Augusti by the imperial troops in Pannonia upon his death.
