Hostilian, born to the Roman Emperor Decius and his wife Herennia Etruscilla, emerged as a significant figure in the tumultuous landscape of the Roman Empire during the third century. His ascent began when he was elevated to the rank of caesar in the year two hundred fifty, a pivotal moment that set the stage for his brief reign.
Tragedy struck when both his father and brother, Herennius Etruscus, met their demise at the Battle of Abritus, a fierce confrontation against the Goths. In the aftermath of this loss, Trebonianus Gallus was proclaimed emperor by the legions, and he quickly recognized Hostilian's potential by elevating him to the position of co-emperor alongside his own son, Volusianus.
Hostilian's reign, however, was short-lived. He faced the dual threats of a devastating plague and the political machinations of Gallus, which ultimately led to his untimely death. The circumstances surrounding his passing remain shrouded in mystery, with theories suggesting he succumbed to the plague or was murdered by Gallus himself.
