Was the last Emperor of the united Roman Empire. Born around the year A.D. 236, on the Dalmatian coast, I was originally named Diocles and was of humble birth.
As a young man, I sought my fortune in the army - showing myself to be a shrewd, able, and ambitious individual. Rising quickly through the military ranks, I received the title of "Duke of Moesia" (an area on the banks of the lower Danube River) along with responsibility for border defense. In A.D. 282, the legions of the upper Danube proclaimed Carus as emperor and under the new emperor I was promoted to Count of the Domestics, the commander of the cavalry arm of the imperial bodyguard.
In A.D. 284, in the midst of a campaign against the Persians, Carus was killed leaving the empire in the hands of his two young sons, Numerian in the east and Carinus in the west. Soon thereafter, Numerian died under mysterious circumstances near Nicomedia, and I was acclaimed emperor in his place. In 285 Carinus was killed in a battle near Belgrade, and I was declared emperor of the entire empire by the Danubian Legions. I took the name Diocletian upon ascending the throne.
