# bio (long form, separated for readability)
bio: |
  Born in September 208, Diadumenian was the son of Macrinus, who took the imperial throne in 217 and promptly named the boy caesar that May. When Elagabalus — a relative of the murdered Caracalla — launched his revolt in May 218, Diadumenian was elevated to full co-emperor in a desperate bid for legitimacy. It didn't hold. Macrinus lost the Battle of Antioch on 8 June 218, and Diadumenian was sent east to the Parthian court for safety. He never made it. Captured en route, the child was executed. The Senate declared both father and son enemies of Rome and ordered their names struck from all records, their images destroyed — the formal erasure scholars now call damnatio memoriae.
