Leo I the Thracian
The reign of Eugenius marked the end of an era and the beginning of a new one. Five months later Theodosius died, dividing his empire between his two sons. This had happened many times before in the previous two centuries, but this time it was to be final – the Roman Empire never reunited, even under Leo I the Thracian (when there was no Western Emperor for some periods), and soon after his reign, the western half fell.
