The Constantinian dynasty is an informal name for the ruling family of the Roman Empire from Constantius Chlorus (†305) to the death of Julian in 363. It is named after its most famous member, Constantine the Great who became the sole ruler of the empire in 324. The dynasty is also called Neo-Flavian because every Constantinian emperor bore the name Flavius, similarly to the rulers of the first Flavian dynasty in the 1st century.
