""Son of Macrinus and Nonia Celsa, was made Caesar at the accession to the throne of his father and proclaimed Augustus by him the following year, 218. One of the points of the peace treaty with the Parths was that Diadumenian would be kept under the care of the Parthian King Artabalus. In the trip to fulfill this condition, the soldiers who were protecting him delivered Diadumedian to the followers of Elegabalus who murder him near Zeugma, today's Belkis, in Turkey.""
