Europe 275: Assassination of Aurelian
Aurelian’s victory in Gaul restored unity to the Roman Empire, a feat the Senate acknowledged by granting him the title Restitutor Orbis (“Restorer of the World”). The emperor then set his sights on Persia only to be assassinated by some of his staff in September 275. His sudden death shocked the army, who turned to the Senate to select a new emperor. Over the ensuing 2–3 months of consultation, there was an interregnum, during which Aurelian’s widow Ulpia Severina seems to have continued to preside as empress.
274 Restitutor Orbis▲
Following his victory in Gaul, Aurelian returned to Rome, where he was given the honorific Restitutor Orbis (“Restorer of the World”) by the Senate. In a magnificent triumph, Zenobia, Tetricus, a Gothic king, and many captives and wild beasts were advanced before his chariot in a procession that lasted until nightfall. Zenobia was afterwards granted a pension and married to a senator, while Tetricus was awarded governorship of the Italian province of Lucania.
25 Dec 274 Sol Invictus▲
In late 274, probably on its festival date of 25 December, Aurelian pronounced Sol Invictus one of the official religions of Rome and dedicated a new temple for Sol. The origins of Sol Invictus, the cult of the “Unconquered Sun”, are uncertain, but it may have been a fusion of the eastern cult of Elagabalus with the ancient Latin cult of Sol, created in a bid to bring unity to the empire. Sol Invictus would continue to be favored by Roman emperors for the next 50 years, until Constantine’s adoption of Christianity.
275 Aurelian’s Vindelician campaign▲
In early 275 Aurelian returned to Gaul to suppress an uprising, possibly in Lugdunum. He then marched to Raetia, where the Vindelici tribe had been overrun by barbarians (generally believed to be the Alemanni, but possibly the newly-arrived Longiones). After expelling the invaders, he may have briefly restored the frontier of the Agri Decumates.
Sep 275 Assassination of Aurelian▲
In the summer of 275 Aurelian mobilized his army to march against Persia and by September was approaching Byzantium. Here his private secretary Eros—who feared Aurelian’s retribution for some misdeed—forged letters to persuade a number of officers that the emperor wanted them dead. Convinced, the officers ambushed and killed Aurelian on the road at Caenophrurium.
Sep–Nov 275 Interregnum of Severina▲
Aurelian’s assassination at the hands of officers so shocked the Roman army that they asked the Senate to select a new emperor, placing the empire into an interregnum while consultations took place. During this period, Aurelian’s widow Ulpia Severina seems to have been acknowledged as empress, with coins being minted in her name. The interregnum lasted for 2–3 months, ending when the Senate proclaimed M. Claudius Tacitus as emperor.
