Aurelian was a Roman emperor, who reigned during the Third Century Crisis, from 270 to 275. As emperor, he won an unprecedented series of military victories which reunited the Roman Empire after it had practically disintegrated under the pressure of barbarian invasions and internal revolts.
Year 270 (CCLXX) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Antiochianus and Orfitus. The denomination 270 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Year 268 (CCLXVIII) was a leap year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Paternus and Egnatius. The denomination 268 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Year 269 (CCLXIX) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Claudius and Paternus. The denomination 269 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Marcus Aurelius Claudius "Gothicus", also known as Claudius II, was Roman emperor from 268 to 270. During his reign he fought successfully against the Alemanni and decisively defeated the Goths at the Battle of Naissus. He died after succumbing to a "pestilence", possibly the Plague of Cyprian that had ravaged the provinces of the Empire.
Marcus Aurelius Probus was Roman emperor from 276 to 282. Probus was an active and successful general as well as a conscientious administrator, and in his reign of six years he secured prosperity for the inner provinces while withstanding repeated invasions of barbarian tribes on almost every sector of the frontier.
The Gallic Empire or the Gallic Roman Empire are names used in modern historiography for a breakaway part of the Roman Empire that functioned de facto as a separate state from 260 to 274. It originated during the Crisis of the Third Century, when a series of Roman military leaders and aristocrats declared themselves emperors and took control of Gaul and adjacent provinces without attempting to conquer Italy or otherwise seize the central Roman administrative apparatus.
Marcus Aurelius Claudius Quintillus was a Roman emperor. He was a brother of Emperor Claudius Gothicus, whom he succeeded after Claudius' death in 270. Quintillus' claim to be emperor was challenged by Aurelian, who was proclaimed emperor by the legions he commanded. Quintillus' reign lasted no more than six months. Different sources report his cause of death as murder by his own soldiers, in battle with Aurelian, or by suicide.
Marcus Cassianius Latinius Postumus was a Roman commander of Batavian origin who ruled as Emperor of the splinter state of the Roman Empire known in contemporary times as the Gallic Empire. The Roman army in Gaul threw off its allegiance to Gallienus around the year 260, and Postumus assumed the title and powers of Emperor in the provinces of Gaul, Germania, Britannia and Hispania, thereby founding what scholars have dubbed the Gallic Empire. He ruled for the better part of ten years before he was murdered by his own troops.
Domitian II was probably a Roman soldier of the mid 3rd century who was acclaimed emperor, probably in northern Gaul in late 270 or early 271, and struck coins to advertise his elevation. It is now generally assumed that this man is to be equated with the Domitianus who is twice mentioned in the literary sources as a significant figure in the politics of the age, but on neither occasion as an outright contender for the Imperial throne.
Marcus Piavonius Victorinus was emperor in the Gallic provinces from 268 to 270 or 269 to 271, following the brief reign of Marius. He was murdered by a jealous husband whose wife he had tried to seduce.
Gaius Pius Esuvius Tetricus was the emperor of the Gallic Empire from 271 to 274 AD. He was originally the praeses (governor) of Gallia Aquitania and became emperor after the murder of Emperor Victorinus in 271, with the support of Victorinus's mother, Victoria. During his reign, he faced external pressure from Germanic raiders, who pillaged the eastern and northern parts of his empire, and the Roman Empire, from which the Gallic Empire had seceded. He also faced increasing internal pressure, which led him to declare his son, Tetricus II, caesar in 273 and possibly co-emperor in 274, although this is debated. The Roman emperor Aurelian invaded in 273 or 274, leading to the Battle of Châlons, at which Tetricus surrendered. Whether this capitulation was the result of a secret agreement between Tetricus and Aurelian or necessary after his defeat is debated. Aurelian spared Tetricus, and even made him a senator and corrector (governor) of Lucania et Bruttium. Tetricus died of natural causes a few years after 274.
Aureolus was a Roman military commander during the reign of Emperor Gallienus before he attempted to usurp the Roman Empire. After turning against Gallienus, Aureolus was killed during the political turmoil that surrounded the Emperor's assassination in a conspiracy orchestrated by his senior officers. Aureolus is known as one of the Thirty Tyrants and is referenced in ancient sources including the Historia Augusta, Zonaras' epitome and Zosimus' Historia Nova, as well as in John Bray's biography of Gallienus.
Eumenius, was one of the Ancient Roman panegyrists and author of a speech transmitted in the collection of the Panegyrici Latini.
The Gallienus usurpers were the usurpers who claimed imperial power during the reign of Gallienus. The existence of usurpers during the Crisis of the Third Century was very common, and the high number of usurpers fought by Gallienus is due to his long rule; 15 years was a long reign by the standards of the 3rd century Roman Empire.
The Illyriciani or Illyrian emperors were a group of Roman emperors during the Crisis of the Third Century who hailed from the region of Illyricum, and were raised chiefly from the ranks of the Roman army. In the 2nd and 3rd centuries, the Illyricum and the other Danubian provinces held the largest concentration of Roman forces, and were a major recruiting ground. The advance of these low-born provincials was facilitated by a major shift in imperial policy from the time of Gallienus (253–268) on, when higher military appointments ceased to be exclusively filled by senators. Instead, professional soldiers of humble origin who had risen through the ranks to the post of primus pilus were placed as heads of the legions and filled the army's command structure.
Appius Claudius Censorinus was a fictional usurper against Roman Emperor Claudius II, according to the unreliable Historia Augusta. He is included in the list of the Thirty Tyrants.
Julius Placidianus was a Roman general of the 3rd century. He was a professional soldier who advanced his career under Gallienus and survived into the age of Claudius II and Aurelian. Placidianus was consul in the year 273 as the posterior colleague of Marcus Claudius Tacitus, the future emperor. His life presented here is largely derived from L.L. Howe's history of the Praetorian Prefecture.
