Publius Licinius Egnatius Gallienus was Roman emperor with his father Valerian from 253 to 260 and alone from 260 to 268. He ruled during the Crisis of the Third Century that nearly caused the collapse of the empire. He won numerous military victories against usurpers and Germanic tribes, but was unable to prevent the secession of important provinces. His 15-year reign was the longest in half a century.
Marcus Claudius Tacitus was Roman emperor from 275 to 276. During his short reign he campaigned against the Goths and the Heruli, for which he received the title Gothicus Maximus.
The 270s decade ran from January 1, 270, to December 31, 279.
Septimia Zenobia was a third-century queen of the Palmyrene Empire in Syria. Many legends surround her ancestry; she was probably not a commoner and she married the ruler of the city, Odaenathus. Her husband became king in 260, elevating Palmyra to supreme power in the Near East by defeating the Sasanian Empire of Persia and stabilizing the Roman East. After Odaenathus' assassination, Zenobia became the regent of her son Vaballathus and held de facto power throughout his reign.
Aurelian was a Roman emperor, who reigned during the Crisis of the Third Century, from 270 to 275. As emperor, he won an unprecedented series of military victories which reunited the Roman Empire after it had nearly disintegrated under the pressure of barbarian invasions and internal revolts. Born in modest circumstances, most likely in Moesia Superior, he entered the Roman army in 235 and climbed up the ranks. He went on to lead the cavalry of the emperor Gallienus, until Gallienus' assassination in 268. Following that, Claudius Gothicus became emperor until his own death in 270. Claudius' brother Quintillus ruled the empire for three months, before Aurelian became emperor.
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.
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.
The Battle of Naissus was the defeat of a Gothic coalition by the Roman Empire under Emperor Gallienus and the future Emperor Aurelian near Naissus. The events around the invasion and the battle are an important part of the history of the Crisis of the Third Century.
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 Aemilius Aemilianus, also known as Aemilian, was Roman emperor for three months in 253.
Magnus Magnentius was a Roman general and usurper against Constantius II from 350 to 353. Of Germanic descent, Magnentius served with distinction in Gaul under the Western emperor Constans. On 18 January 350 Magnentius was acclaimed Augustus. Quickly killing the unpopular Constans, Magnentius gained control over most of the Western Empire. The Eastern emperor Constantius II, the brother of Constans, refused to acknowledge Magnentius' legitimacy and led a successful campaign against Magnentius in the Roman civil war of 350–353. Ultimately, Magnentius' forces were scattered after the Battle of Mons Seleucus, and he committed suicide on 11 August 353.
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.
Marcus(?) Aurelius Heraclianus was a Roman soldier who rose to the rank of Praetorian Prefect in the latter part of the reign of the Emperor Gallienus. He was a member of the cabal of senior commanders of the Imperial field army that plotted and achieved the assassination of the Emperor Gallienus. His subsequent fate is uncertain. The only ancient reference has him committing suicide, but the circumstances are unclear.
Claudia was the purported mother of Roman emperor Constantius Chlorus according to ancient sources. These sources claim her to be a relative of Roman emperors Claudius Gothicus and Quintillus, a claim modern historians tend to view with suspicion.
The barbarian invasions of the third century (212-305) constituted an uninterrupted period of raids within the borders of the Roman Empire, conducted for purposes of plunder and booty by armed peoples belonging to populations gravitating along the northern frontiers: Picts, Caledonians, and Saxons in Britain; the Germanic tribes of Frisii, Saxons, Franks, Alemanni, Burgundians, Marcomanni, Quadi, Lugii, Vandals, Juthungi, Gepids and Goths, the Dacian tribes of the Carpi and the Sarmatian tribes of Iazyges, Roxolani and Alans, as well as Bastarnae, Scythians, Borani and Heruli along the Rhine-Danube rivers and the Black Sea.
Roman Aquileia was founded in 181 BC by the Romans, in the territory of the ancient Carni:
In the same year [181 BC] the colony of Aquileia was deducted in the territory of the Gauls. 3 000 infantrymen received 50 iugera each, the centurions 100, the horsemen 140. The triumvirs who founded the colony were Publius Scipio Nasica, Gaius Flaminius, and Lucius Manlius Acidinus.
