Discontent within the Roman military grew under Emperor Macrinus following the murder of Caracalla in 217. Macrinus' costly peace with Parthia and policies reducing military pay fueled resentment. Julia Maesa, Caracalla's aunt, exploited this unrest by funding a campaign to install her grandson Elagabalus, who was proclaimed emperor by Legio III Gallica on 16 May 218.
On 8 June 218, forces loyal to Macrinus clashed with those of Elagabalus, commanded by General Gannys, near Antioch. Although Macrinus' Praetorian Guards initially broke through enemy lines, Elagabalus' mother and grandmother rallied the fleeing troops. Gannys led a renewed assault, causing Macrinus to abandon the battlefield and flee to Antioch.
Macrinus' flight effectively ended his reign. He dispatched his son and co-emperor Diadumenian to Parthia while attempting to return to Rome, but both were captured and executed. The Senate, with Macrinus dead, was compelled to recognize Elagabalus as emperor. Elagabalus himself was eventually killed by the Praetorian Guard in March 222 and subjected to damnatio memoriae.
