Theodosius

Count Theodosius was sent by the emperor Valentinian I to restore order in Britain after the Barbarian Conspiracy of AD 367. His measures probably included rebuilding work on Hadrian's Wall, the construction of early-warning signal stations on the Yorkshire coast, and the addition of bastions to the walls of towns. Unlike many army commanders of this time, he was a provincial landowner rather than a career soldier. He was made emperor in AD 379 and reigned until his death in AD 395.
