DIADVMENIAN

Reigned: 217-218 A.D.


MARCVS OPELLIVS DIADVMENIANVS was appointed Caesar at the age of 9 when his father Macrinus obtained the purple through a coup against Caracalla in 217 A.D. To associate his son with the imperial legacy of the Antonine and Severan dynasty, Macrinus gave him the added name of ANTONINVS. Diadumenian was raised by his father to the rank of Co-Augustus around May, 218.
After a brief reign of 14 months Macrinus was overthrown and killed by in June 218 by forces loyal to Julia Maesa and Elagabalus. The young Co-Augustus attempted to flee to Parthia, but was captured and executed.
