Magnus Magnentius (c. 303 – 10 August 353) was a Roman general and usurper against Constantius II. Of Germanic descent, Magnentius served with distinction in Gaul under the 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. Ultimately, Magnentius' forces were scattered after the Battle of Mons Seleucus, and he died by suicide on 10 August 353. [8]
Much of Magnentius' short reign was concerned with asserting his legitimacy. Unlike Constans, Magnentius was unrelated to Constantine the Great, and so had no dynastic claim to the emperorship. Magnentius instead sought popular support by modeling himself as a liberator who had freed the Western Empire from the tyranny of Constans. He attempted various public and religious reform, but almost all his acts were quickly repealed by Constantius after his death. [8] In light of the political instability of his reign, modern and ancient historians tend to consider him a usurper rather than an emperor.
Perhaps the most important consequence of Magnentius' revolt was the severe depletion of the Empire's military forces in civil war: The Battle of Mursa left so many Roman soldiers dead that, according to Zosimus, Constantius feared that Rome would no longer be able to effectively hold off barbarian invasions. [9] [10] Following his death, Constantius II became the sole emperor of the Roman Empire.
Born in Samarobriva (Amiens), Gaul, Magnentius was purportedly the son of a British father and a Frankish mother, [11] [12] [13] though some scholars suspect that his supposed origins were exaggerated or invented as a result of Constantinian propaganda. [14] [15] [note 3] He served in the protectores, a prestigious bodyguard corps attached to the imperial retinue, and was promoted to comes of the Herculians and Jovians, the Imperial guard units. [17] [3] Magnentius seems to have been effective in his post and to have been well-liked by other important court officials, notably Marcellinus, the comes rerum privatarum, who supported his usurpation. [17]
Court officials eventually hatched a plot to overthrow Constans and place Magnentius in power. By 350, Constans was likely deeply unpopular; ancient sources deride him as licentious, incompetent, and homosexual. [18] [11] [17] There is confusion as to the details, but in Augustulum (Autun) on 18 January 350 Magnentius announced his bid for power by attending a dinner party, stepping out for a moment, and re-entering the room in a purple toga (the traditional dress of an emperor). The party-goers, either all [19] or in part [20] in on the plot, hailed him Augustus. [21] [22]
In the days following his acclamation, Magnentius bribed the city guard to secure their loyalty and barred residents of Augustulum from leaving the city to prevent the spread of the news. Anxious to eliminate Constans—who was then hunting near the Pyrenees away from his forces—Magnentius sent a contingent to run him down, and Constans was killed at Helena (near Perpignan). [16] [11] [21] Zosimus claims this force was headed by Gaiso, and that his consulship in 351 was a reward for this act. [21] [23]
Magnentius quickly attracted the loyalty of the provinces of Britannia, Gaul, and Hispania, and immediately moved to control Italy. He did so within a month of his ascension, appointing Fabius Titianus to the position of praefectus urbis to govern Rome. [11] He seems to have secured Africa quickly as well, thus inheriting all of Constans' former territory except Illyria (which would shortly come under the control of Vetranio).
Magnentius' early reign is marked by a series of bids for political legitimacy. Lacking a connection to the Constantinian dynasty, Magnentius married Justina, possibly a great-granddaughter of Constantine (and future wife of Valentinian). [24] Magnentius attempted to create an image of himself as a liberator, and minted coins with such inscriptions as 'liberator of the Roman world.' [24] [25] Further, Magnentius seems to have initially pursued a policy of diplomacy with Constantius, hoping to induce the emperor to recognize him officially: for the first six months of his reign, Magnentius spoke of Constantius as his senior and minted coins bearing his image. [11] Magnentius also appealed to the controversial bishop Athanasius—who in the end chose to side with Constantius—and repealed some of Constans' restrictions on pagan sacrifice in Italy. This latter decision, aimed at winning the support of wealthy Italian pagans, proved to be a rather crude political maneuver, and earned Magnentius a reputation as a pagan himself. [24] [26]
Despite his efforts Magnentius remained politically vulnerable. Constantius reasoned that legitimizing the man who murdered his brother would set an unacceptable precedent, and so prepared to march West. In Italy, Magnentius' hold over Rome proved tenuous, and Julius Nepotianus, Constantine's nephew, took and held the city for 27 days. Magnentius dispatched Marcellinus (now promoted to magister officiorum ) to retake the city. [27] In Illyria, Vetranio was acclaimed emperor with the support of Constantius' sister Constantina on 1 March 350. [28] [11] Though he publicly allied with Magnentius, many modern scholars contend that Vetranio was working for Constantius from the beginning, preventing Magnentius from threatening Constantinople until Constantius could march West. [11]
There is little evidence to suggest that Magnentius' rule was tyrannical or unjust. In a funeral oration for the emperor Julian, the orator Libanius concedes that Magnentius "governed [the empire] in accordance with the laws." This, along with the speed with which he attracted the provinces of Britain and Hispania, may indicate that his administration was relatively competent. [29]
By the summer of 350 it had become clear that war was inevitable between Constantius and Magnentius. [11] Magnentius had already moved east over the spring, and appointed his brother Decentius as caesar to control Gaul during his absence. [30] In the East, Constantius was tied down for most of 350 in his War against the Persians. However, in the autumn of 350 Constantius successfully lifted the Persian siege of Nisibis and forged a nominal peace with the Sasanids. [31] [32] Appointing Constantius Gallus caesar and entrusting command of the Eastern legions to Lucillianus, Constantius moved West. On 25 December 350 he accepted Vetranio’s resignation in Illyria. [33] [34]
Constantius and Magnentius wintered far apart, and, in the early months of 351, both parties flirted with the idea of peace. [32] Constantius offered Magnentius control of Gaul, which Magnentius rejected. [30] [35] Magnentius' force may have been slowly deserting him, [35] for he seems to have pushed for a battle: [36] either the night before the battle or long before (accounts conflict) the important commander Silvanus defected to Constantius. [30] After failing to take the city of Mursa, Magnentius' force was approached by Constantius', and the Battle of Mursa Major ensued. Constantius won a Pyrrhic victory in one of the largest battles ever fought among Romans: low estimates suggest there were over 50,000 deaths. The sight of the field is reported to have reduced Constantius to tears, and to have made him fear that Rome would be unable to resist Barbarian invasion. [35] Contemporary commentators like Eutropius lament the loss, noting that enough men for an entire foreign invasion were lost. [37]
Magnentius retreated across the Alps, perhaps after being prevented from entering Italy by the erection of garrisons loyal to Constantius. [34] Magnentius blocked the passages West, and Constantius engaged in skirmishes with the barbarians to the Northeast for the rest of the year. [39]
The year 352 is marked by Magnentius' failed attempts to broker a peace with Constantius: Magnentius sent an embassy to Constantius who, worried about espionage, prevented them reaching him. Magnentius then sent an assembly of bishops with the message that he was willing to step down and take a soldier's posting under Constantius. Constantius rejected this offer as well. [10] Magnentius' legions along the Rhine began defecting en masse, access to northern Gaul and Spain was blocked, and, in the end, he was unable to effectively prevent defection even in his camp. [26]
At some time in the year 353, Magnentius may have attempted to assassinate Constantius Gallus, Constantius' caesar, in a bid to open the Eastern empire to attack. The incident is mentioned only in the account of Zonaras, though some scholars see a passage in Ammianus Marcellinus as corroborating it. However, some modern scholars have claimed that Zonaras' account contains chronological problems, and thus the historicity of this event is uncertain. [40] In any case, if the plot did exist, it was foiled, as Gallus outlived the civil war.
Constantius crossed the Alps in 353, [8] and Magnentius made a final stand in July of the same year at the Battle of Mons Seleucus, after which he fled to Lugdunum (Lyon). There, some sources report that his home was surrounded by the forces of Constantius and that he lashed out against his brother Desiderius. [note 4] However, most sources agree that, on 10 August 353, he died by suicide by falling on his sword. [8] [43] [44] His brother Decentius hanged himself when he received the news. [8] [43]
Following the suppression of Magnentius' rebellion, Constantius began to root out his followers. The most notorious agent he employed in this search was the primicerius notariorum Paulus Catena ("Paul the Chain").
Magnentius' religious beliefs remain a point of contention among scholars. Many argue that Magnentius was, at least nominally, a Christian. [24] [45] However, some sources hint at a pagan restoration during his short reign. Epigraphic evidence suggests that he allowed pagans to perform sacrifices at night, a practice that had been banned by Constans. [24] Philostorgius describes Magnentius as a demon worshiper, and Zonaras recounts a story of him using black magic. [44] Numismatically, Magnentius' coinage is neither distinctively pagan nor Christian, with the exception of a series of coins bearing a Christogram. [46] This symbol has come to be associated solely with Christianity, but this may not reflect attitudes at the time: MacMullen argues that Magnentius was a Pagan, and that the Chi-Rho had been so de-Christianized by the mid fourth century that he could use it freely. [47]
Constantius II was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.
Flavius Julius Constans, also called Constans I, was Roman emperor from 337 to 350. He held the imperial rank of caesar from 333, and was the youngest son of Constantine the Great.
Constantine II was Roman emperor from 337 to 340. The son of the emperor Constantine I, he was proclaimed caesar by his father shortly after his birth. He was associated with military victories over the Sarmatians, Alamanni and Goths during his career, for which he was granted a number of victory titles. He held the consulship four times – in 320, 321, 324, and 329.
Julian was the Caesar of the West from 355 to 360 and Roman emperor from 361 to 363, as well as a notable philosopher and author in Greek. His rejection of Christianity, and his promotion of Neoplatonic Hellenism in its place, caused him to be remembered as Julian the Apostate in Christian tradition. He is sometimes referred to as Julian the Philosopher.
The 350s decade ran from January 1, 350, to December 31, 359.
Year 350 (CCCL) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Nigrinianus. The denomination 350 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.
Vetranio was briefly an imperial usurper and emperor in the Roman Empire in 350, during which time he controlled Illyricum between the rival emperors Magnus Magnentius and Constantius II, eventually capitulating to the latter.
Nepotianus, sometimes known in English as Nepotian, was a member of the Constantinian dynasty who reigned as a short-lived usurper of the Roman Empire. He ruled the city of Rome for twenty-eight days, before being killed by his rival usurper Magnentius' general Marcellinus.
Justina was a Roman empress. She was initially the wife of the rebel emperor Magnentius and was then married to Valentinian I, with whom she had four children, including the emperor Valentinian II and the empress Galla.
The Battle of Mursa was fought on 28 September 351 between the eastern Roman armies led by the Emperor Constantius II and the western forces supporting the usurper Magnentius. It took place at Mursa, near the Via Militaris in the province of Pannonia. The battle, one of the bloodiest in Roman history, was a pyrrhic victory for Constantius.
The Battle of Mons Seleucus was fought in 353 between the armies of the Roman emperor Constantius II and the usurper Magnentius. Constantius' forces were victorious. Support for Magnentius had been eroding since his defeat at the Battle of Mursa Major two years prior; after Mons Seleucus his cause collapsed and he killed himself.
