Honorius was Roman emperor from 393 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla. After the death of Theodosius in 395, Honorius, under the regency of Stilicho, ruled the western half of the empire while his brother Arcadius ruled the eastern half. His reign over the Western Roman Empire was notably precarious and chaotic. In 410, Rome was sacked for the first time in almost 800 years.
The 270s decade ran from January 1, 270, to December 31, 279.
The 260s decade ran from January 1, 260, to December 31, 269.
Flavius Valerius Constantius "Chlorus", also called Constantius I, was Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome. The nickname Chlorus was first popularized by Byzantine-era historians and not used during the emperor's lifetime.
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.
Constantine III was a common Roman soldier who was declared emperor in Roman Britain in 407 and established himself in Gaul. He was recognised as co-emperor of the Roman Empire from 409 until 411.
Marcus Cassianius Latinius Postumus was a Roman commander of Batavian origin, who ruled as emperor of the splinter state of the Roman Empire known to modern historians 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. He ruled for the better part of ten years before he was murdered by his own troops.
Legio XIV Gemina was a legion of the Imperial Roman army, levied by Julius Caesar in 57 BC. The cognomen Gemina (Twinned) was added when the legion was combined with another understrength legion after the Battle of Actium. The cognomen Martia Victrix was added following their service in the Pannonian War c. AD 9 and the defeat of Boudicca in AD 61. The emblem of the legion was the Capricorn, as with many of the legions levied by Caesar.
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.
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.
The end of Roman rule in Britain was the transition from Roman Britain to post-Roman Britain. Roman rule ended in different parts of Britain at different times, and under different circumstances. In 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. In 407, usurper Constantine III took the remaining mobile Roman soldiers to Gaul in response to the crossing of the Rhine in late 406, leaving the island a victim to barbarian attacks. Around 410, the Romano-British expelled the Roman magistrates from Britain. Roman Emperor Honorius replied to a request for assistance with the Rescript of Honorius, telling the Roman cities to see to their own defence, a tacit acceptance of temporary British self-government. Honorius was fighting a large-scale war in Italy against the Visigoths under their leader Alaric, with Rome itself under siege. No forces could be spared to protect distant Britain. Though it is likely that Honorius expected to regain control over the provinces soon, by the mid-6th century Procopius recognised that Roman control of Britannia was entirely lost.
Marcus was a Roman usurper who was proclaimed Emperor of Roman Britain. He was killed later that same year in a subsequent mutiny.
Gratian or Gratianus was a Roman usurper in Roman Britain from 406-407.
Victoria, also known as Vitruvia, was a leader in the Roman breakaway realm known as the Gallic Empire in the late 3rd century. She was the mother of Victorinus, who ruled as Gallic Emperor until his assassination in 271. Afterwards, Victoria used her authority to stabilize the empire and select a successor. For a few weeks, Victorina was considered as de facto empress of Gaul, from the death of Victorinus to the accession of Tetricus I. She took the throne as the reigning monarch.
Victorinus was emperor of the secessionist Gallic Empire in the late 3rd century.
The crossing of the Rhine River by a mixed group of barbarians which included Vandals, Alans and Suebi is traditionally considered to have occurred on the last day of the year 406. The crossing transgressed one of the Late Roman Empire's most secure limites or boundaries and so it was a climactic moment in the decline of the Empire. It initiated a wave of destruction of Roman cities and the collapse of Roman civic order in northern Gaul. That, in turn, occasioned the rise of three usurpers in succession in the province of Britannia. Therefore, the crossing of the Rhine is a marker date in the Migration Period during which various Germanic tribes moved westward and southward from southern Scandinavia and northern Germania.
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.
The Siege of Augustodunum Haeduorum took place in 269-270, Augustodunum. Victorinus had been declared emperor by the troops located at Augusta Treverorum in the fall of 269. However, only the provinces of Gaul, Germania and Britain recognised him.
