10Justinian (482 AD – 14 November, 565 AD)

Though the Western Roman Empire had already fallen to the barbarians by 476 AD, the Eastern Roman Empire saw one last reign under Justinian I, who ruled the east (also called the Byzantine Empire) from 526 to 565 AD.

During his reign, Justinian sought to revive the empire’s greatness and reconquer the lost western half. His great generals Belisarius and Narses reconquered many parts of the empire, including the city of Rome itself. Because of his restorative activities, Justinian has sometimes been called “the last Roman” in modern history.
