Born of humble origin around A.D. 245 in Dalmatia near Split, Diocletian bought order to the Roman world after nearly 60 years of chaos. Like many of his predecessors, he had a military career, rising through the ranks to high command. Following the murder of the emperor Numerian, Diocletian was proclaimed emperor by his troops. Then the defeat of Carinus (brother of Numerian) left Diocletian in undisputed control of the Empire. Having realised the empire was too big for one person alone he quickly appointed an old army colleague, Maximian, as co-emperor. He also settled the problem of succession by the appointment of two junior Caesars, one for himself and Maximian. Diocletian spent much of his reign campaigning against Rome’s enemies on the Danube frontier, in North Africa, Egypt and Syria. Although there were Christians at all levels of society at this time, Diocletian worshipped the old Roman gods and was responsible for A savage persecution of Christians. Diocletian was a prolific builder and did much to overhaul the tax system and reform the coinage in an attempt to counter inflation. He abdicated in A.D. 305 and retired to his palace in Split. He died there in A.D. 311 a broken man, having watched his reforms trampled to death by the likes of Constantine the Great and Licinius.
