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.

The Eastern Roman Empire was ruled by the Theodosian dynasty from 379, the accession of Theodosius I, to 457, the death of Marcian. The rule of the Theodosian dynasty saw the final East-West division of the Roman Empire, between Arcadius and Honorius in 395. Whilst divisions of the Roman Empire had occurred before, the Empire would never again be fully reunited. The reign of the sons of Theodosius I contributed heavily to the crisis that under the fifth century eventually resulted in the complete collapse of western Roman court.
