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.

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.
Domitian II was 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.
Gaius Pius Esuvius Tetricus was a Gallo-Roman nobleman who ruled as emperor of the Gallic Empire from 271 to 274 AD. He was originally the praeses 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 that surrender was necessary after his defeat is debated. Aurelian spared Tetricus, and made him a senator and the corrector (governor) of Lucania et Bruttium. Tetricus died of natural causes a few years after 274.
Gaius Pius Esuvius Tetricus, better known as Tetricus II, was the son and heir of Tetricus I, emperor of the Gallic Empire from 271 to 274 AD.
Septimius Vaballathus was emperor of the Palmyrene Empire centred at Palmyra in the region of Syria. He came to power as a child under his regent mother Zenobia, who led a revolt against the Roman Empire and formed the independent Palmyrene Empire.
In the Battle of Châlons, fought in 274 on the site of modern Châlons-en-Champagne, France, Roman Emperor Aurelian defeated Emperor Tetricus I of the Gallic Empire, whose territories were rejoined with the Roman Empire after fourteen years of separation.
The Palmyrene Empire was a short-lived breakaway state from the Roman Empire resulting from the Crisis of the Third Century. Named after its capital city, Palmyra, it encompassed the Roman provinces of Syria Palaestina, Arabia Petraea, and Egypt, as well as large parts of Asia Minor.
