Aurelian born near Byzantium (now Istanbul) in AD 214, was a Roman emperor from 270 - 275 AD. By reuniting the empire, which had virtually disintegrated under the pressures of invasions and internal revolts, he earned his self-adopted title restitutor orbis (restorer of the world). Aurelian was an Army officer in AD 260, when the frontiers of the empire suddenly collapsed.
With his compatriot Claudius, Aurelian led the cavalry of the emperor Gallienus (253-268 AD). Upon Gallienus's assassination in 268 AD, Claudius became the emperor. The new ruler quickly suppressed the rebellion of the usurper Aureolus, but after a reign of 18 months, Claudius died. His brother Quintillus, who ruled about three months, died or was killed, and in September 270 AD, Aurelian succeeded as emperor.
Aurelian quickly started to restore the Roman authority in Europe. First, he turned back the Vandals from Pannonia (present day central Europe. After a series of battles, he expelled the Alemanni and Juthunngi across the Danube. He ordered the construction of a new city wall around Rome, which still stands and bears his name.
In 271 AD, he sought to recover the eastern provinces which for 10 years had obeyed the rule of the princes of Palmyra. He captured Palmyra, and when Palmyra revolted a second time in 273 AD, Aurelian recaptured and destroyed the city.
In 274 AD, he returned west to confront Tetricus, the rival emperor, who controlled Gaul, Spain and Britain. Beset by a German invasion and by internal conspiracies, Tetricus concluded a secret treaty with Aurelian, deserting to him at the battle of Chalons. The leaderless army of the Rhine was swiftly defeated. Thus, the vast empire was again ruled by a central authority.
Aurelian was an outstanding general and an uncompromising administrator. He attempted to reform the silver coinage, debased for more than 40 years. Early in 275 AD, while marching to open a campaign against Persia, Aurelian was murdered by a group of officers who had been misled by his secretary into believing themselves marked for execution. The government continued in the name of Aurelian's widow, Ulpia Severina, till the next six months, till the appointment of Marcus Claudius Tacitus to the throne. The empire remained divided until Diocletian's ascension in AD 284.
Aurelian's most significant achievement is the one he was completely unaware of. He introduced a new deity to the Romans, a solar god, Sol Invictus, the invincible Sun. This paved a way for the oriental cult towards emergence of Christianity as an official religion decades later. The birthday of Aurelian's god is December 25th, the same day celebrated as Christmas today.
