A romur

Alexander Severus was adopted as son and caesar by his slightly older and very unpopular cousin, the emperor Elagabalus at the urging of the influential and powerful Julia Maesa — who was the grandmother of both cousins and who had arranged for the emperor's acclamation by the Third Legion. On March 6, 222, when Alexander was just fourteen, a rumor went around the city troops that Alexander had been killed, triggering a revolt of the guards that had sworn his safety from Elegabalus and his accession as emperor.
