The Theodosian dynasty was a Roman imperial family that produced five Roman emperors during Late Antiquity, reigning over the Roman Empire from 379 to 457. The dynasty's patriarch was Theodosius the Elder, whose son Theodosius the Great was made Roman emperor in 379. Theodosius's two sons both became emperors, while his daughter married Constantius III, producing a daughter that became an empress and a son also became emperor. The dynasty of Theodosius married into, and reigned concurrently with, the ruling Valentinianic dynasty, and was succeeded by the Leonid dynasty with the accession of Leo the Great.
