Elagabalus ascended to the imperial throne at a young age in 218, after the death of the previous emperor, Macrinus. His reign is often remembered for its extravagance and controversial religious reforms, particularly his promotion of the sun god Elagabal, which alienated many of the traditional Roman political and military elites. Tensions culminated in political unrest as his increasingly autocratic style and the influence of his mother, Julia Soaemias, became points of contention. The military, key to maintaining power in Rome, began to turn against him due to dissatisfaction with his policies and perceived inability to govern effectively.

In March 222, the tide turned decisively when the Praetorian Guard, the elite soldiers tasked with protecting rulers, orchestrated a coup. They killed Elagabalus and Julia Soaemias in a brutal confrontation. The young emperor's death marked a significant shift in the governance of Rome, as the throne then passed to his cousin, Severus Alexander. Only 14 at the time, Alexander was selected in part because he was seen as a compromise candidate who could restore stability to the empire and soothe the discontent simmering among the military and the Senate.

Severus Alexander's early rule was characterized by attempts to reconcile differing factions and restore a sense of order. The murder of Elagabalus highlights the extent to which imperial power was contingent on military support and public approval, illustrating the volatile nature of Roman imperial politics. This event is not just a personal tragedy but a pivotal moment in the broader narrative of Roman governance.
