Marcus Aurelius Claudius "Gothicus" (10 May 214 – January/April 270), 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 most significant source for Claudius II is the collection of imperial biographies called the Historia Augusta. However, his story, like the rest of the Historia Augusta, is riddled with fabrications and obsequious praises. In 4th century, Claudius was declared a relative of Constantine the Great's father, Constantius Chlorus, and, consequently, of the ruling dynasty. The Historia Augusta should be used with extreme caution and supplemented with information from other sources: the works of Aurelius Victor, Pseudo-Aurelius Victor, EutropiusOrosiusJoannes Zonaras, and Zosimus, as well as coins and inscriptions.

The future emperor Marcus Aurelius Claudius was born on 10 May 214. Some researchers suggest a later date – 219 or 220.Nevertheless, most historians adhere to the first version. Moreover, as the 6th century Byzantine historian John Malalas reports, at the time of his death Claudius was 56 years old.Claudius was an Illyrian and came from Dalmatia or Illyricum, although it is possible that his place of birth was the region of Dardania in Moesia Superior.

According to the fourth-century Epitome de Caesaribus, he was thought to be a bastard son of Gordian II, although this is doubted by some historians.

The Historia Augusta refers to him as a member of the gens Flavia, likely an attempt to further connect him with the future emperor Flavius Valerius Constantius.Before coming to power, Claudius served with the Roman army, where he had a successful career and secured appointments to the highest military posts. During the reign of Decius (249–251) he served as a military tribune. In this post, Claudius was sent to defend Thermopylae, in connection with which the governor of Achaea was ordered to send him 200 Dardanian soldiers, 60 horsemen, 60 Cretan archers, and a thousand well-armed recruits. However, there is no evidence that the Goths who invaded at that time threatened the region, since their invasion did not extend beyond the middle Balkans. Most likely the message of the "History of the Augustus" is an anachronism, since it is known that the garrison at Thermopylae appeared in 254. Historian François Pashau suggests that this passage was invented in order to contrast the successful pagan commander Claudius with the unlucky Christian generals who allowed the ruin of Greece by the Gothic leader Alaric I in 396. In addition, Trebellius Pollio reveals that Decius rewarded Claudius after he demonstrated his strength while fighting another soldier at the Games of Mars.

His troops then proclaimed him emperor amid charges, never proven, that he murdered his predecessor Gallienus.However, he soon showed himself to be less than bloodthirsty, as he asked the Roman Senate to spare the lives of Gallienus's family and supporters. He was less magnanimous toward Rome's enemies and it was to this that he owed his popularity.

It is possible Claudius gained his position and the respect of the soldiers by being physically strong and especially cruel. A legend tells of Claudius knocking out a horse's teeth with one punch. When Claudius performed as a wrestler in the 250s, he supposedly knocked out the teeth of his opponent when his genitalia had been grabbed in the match.

Claudius, like Maximinus Thrax before him, was of barbarian birth. After a period of failed aristocratic Roman emperors following Maximinus's death, Claudius was the first in a series of tough "soldier emperors" who would eventually restore the Empire after the Crisis of the Third Century.


Downfall of Gallienus

During the 260s, the breakup of the Roman Empire into three distinct governing entities (the core Roman Empire, the Gallic Empire and the Palmyrene Empire) placed the whole Roman imperium in a precarious position. Gallienus was seriously weakened by his failure to defeat Postumus in the West, and his acceptance of Odaenathus ruling a de facto independent kingdom within the Roman Empire in the East. By 268, this situation had changed, as Odaenathus was assassinated, most likely due to court intrigue, and Gallienus fell victim to a mutiny in his own ranks. Upon the death of Odaenathus, power fell to his younger son, who was dominated by his mother, Zenobia.

Under threat of invasion in the Balkans by multiple Germanic tribes, Gallienus's troubles primarily lay with Postumus, whom he could not attack because his attention was required in dealing with an insurrection led by Macrianus and the threats created by the invading Scythians. After four years of delay, Postumus had established some control over the Empire. In 265, when Gallienus and his men crossed the Alps, they defeated and besieged Postumus in an (unnamed) Gallic city. When victory appeared to be near, Gallienus made the mistake of approaching the city walls too closely and was gravely injured, compelling him to cease his campaign against Postumus. Over the next three years, Gallienus's troubles only got worse. The Scythians successfully invaded the Balkans in the early months of 268, and Aureolus, a commander of the Roman cavalry based in Milan, declared himself an ally of Postumus and went so far as to claim the imperial throne for himself.

At this time, another invasion was taking place. In 268, a tribe or grouping called the Herulians moved through Asia Minor and then into Greece on a naval expedition. Despite this, scholars assume Gallienus's efforts were focused on Aureolus, the officer who betrayed him, and the defeat of the Herulians was left to his successor, Claudius Gothicus.

The death of Gallienus was surrounded by conspiracy and betrayal, as were many emperors' deaths. Different accounts of the incident have been recorded, but they agree that senior officials wanted Gallienus dead. According to two accounts, the prime conspirator was Aurelius Heraclianus, the Praetorian Prefect. One version of the story tells of Heraclianus bringing Claudius into the plot while the account given by the Historia Augusta exculpates the soon-to-be emperor and adds the prominent general Lucius Aurelius Marcianus into the plot. The removal of Claudius from the conspiracy may be due to his later role as the progenitor of the house of Constantine, a fiction of Constantine's time, and suggests that the original version from which these two accounts derive was current prior to the reign of Constantine. It was written that while sitting down at dinner, Gallienus was told that Aureolus and his men were approaching the camp. Gallienus rushed to the front lines, ready to give orders, when he was struck down by a commander of his cavalry. In a different and more controversial account, Aureolus forges a document in which Gallienus appears to be plotting against his generals and makes sure it falls into the hands of the emperor's senior staff. In this plot, Aurelian is added as a possible conspirator. The tale of his involvement in the conspiracy might be seen as at least partial justification for the murder of Aurelian himself under circumstances that seem remarkably similar to those in this story.

Whichever story is true, Gallienus was killed in the summer of 268, probably between July and October,[20][21][5] and Claudius was chosen by the army outside of Milan to succeed him. Accounts tell of people hearing the news of the new emperor, and reacting by murdering Gallienus's family members until Claudius declared he would respect the memory of his predecessor. Claudius had the deceased emperor deified and buried in a family tomb on the Appian Way. The traitor Aureolus was not treated with the same reverence, as he was killed by his besiegers after a failed attempt to surrender.


Campaigns

At the time of Claudius's accession, the Roman Empire was in serious danger from several incursions, both inside and outside its borders. The most pressing of these was an invasion of Illyricum and Pannonia by the Goths.Although Gallienus had already inflicted some damage on them at the Battle of Nestus, Claudius, not long after being named emperor, followed this up by winning his greatest victory, and one of the greatest in the history of Roman arms.At the Battle of Naissus, Claudius and his legions routed a huge Gothic army.Together with his cavalry commander, the future Emperor Aurelian, the Romans took thousands of prisoners and destroyed the Gothic cavalry as a force. The victory earned Claudius his surname of "Gothicus" (conqueror of the Goths). The Goths were soon driven back across the Danube River by Aurelian, and nearly a century passed before they again posed a serious threat to the empire.

Around the same time, the Alamanni had crossed the Alps and attacked the empire. Claudius responded quickly, routing the Alamanni at the Battle of Lake Benacus in the late fall of 268, a few months after the Battle of Naissus.For this he was awarded the title of "Germanicus Maximus." He then turned on the Gallic Empire, ruled by a pretender for the past eight years and encompassing BritainGaul, and the Iberian Peninsula. He won several victories and soon regained control of Hispania and the Rhone river valley of Gaul.This set the stage for the later destruction of the Gallic Empire under Aurelian.

Claudius did not live long enough to fulfil his goal of reuniting all the lost territories of the empire. Late in 269 he had travelled to Sirmium and was preparing to go to war against the Vandals, who were raiding in Pannonia. However, he fell victim to the Plague of Cyprian (possibly smallpox), and died early in 270.Before his death, he is thought to have named Aurelian as his successor, though Claudius's brother Quintillus briefly seized power.The Senate immediately deified Claudius as "Divus Claudius Gothicus".the city of Autun, but sources tell us his relations with Palmyra were waning in the course of 269. An obscure passage in the Historia Augusta's life of Gallienus states that he had sent an army under Aurelius Heraclianus to the region that had been annihilated by Zenobia. But because Heraclianus was not actually in the east in 268 (instead, at this time, he was involved in the conspiracy of Gallienus's death), this cannot be correct. But the confusion evident in this passage, which also places the bulk of Scythian activity during 269 a year earlier, under Gallienus, may stem from a later effort to pile all possible disasters in this year into the reign of the former emperor. This would keep Claudius's record of being an ancestor of Constantine from being tainted. If this understanding of the sources is correct, it might also be correct to see the expedition of Heraclianus to the east as an event of Claudius's time.

Historians date Claudius's death in either January, April, August, or September. These discrepancies are the result of the various conflicting sources. The Chronograph of 354 gives Claudius a reign of "1 year and 4 months", Jerome and Aurelius Victor both give "1 year and 9 months".Some Alexandrian coins have been dated to his third year, suggesting that he died in September 270.[

 However, the first document of Aurelian is dated to 25 May 270.upon Odaenathus; the title rex, or king, is simply a Latin translation of mlk, or king; imperator in this context simply means "victorious general"; and dux Romanorum looks like yet another version of corrector totius orientis" (Potter, 263). These titles suggest that Odaenathus's position was inheritable. In Roman culture, the status gained in procuring a position could be passed on, but not the position itself. It is possible that the thin line between office and the status that accompanied it were dismissed in the Palmyrene court, especially when the circumstance worked against the interests of a regime that was able to defeat Persia, which a number of Roman emperors had failed to do. Vaballathus stressed the meanings of titles, because in the Palmyrene context, the titles of Odaenathus meant a great deal. When the summer of 270 ended, things were looking very different in the empire than they did a year before. After its success, Gaul was in a state of inactivity and the empire was failing in the east. Insufficient resources plagued the state, as a great deal of silver was used for the antoninianus, which was again diluted
