Roman People > Postumus


Marcus Cassianius Latinius Postumus[3] was a Roman commander of provincial origin who ruled as emperor in the west. The Roman army in Gaul threw off its allegiance to Gallienus around the year 260,[note 1] and Postumus assumed the title and powers of emperor in the provinces of Gaul, Germania, Britannia and Hispania, thereby founding what scholars have dubbed the Gallic Empire. He ruled for the better part of ten years[note 2] before he was murdered by his own troops.

He has been claimed as a Batavian;[4] certainly his coinage honours deities—Hercules Magusanus and Hercules Deusoniensis—who would have been popular among the Batavians.[5] Hercules Magusanus was probably an interpretatio romana translation of the Germanic deity Donar.[6] Deusoniensis may refer to the town of Deuso, located in or near Batavian territory and likely to be identified with Diessen; it has been hypothesized that Postumus himself was born in Deuso.[7] From these relatively obscure provincial origins, Postumus would have risen through the ranks of the army until he held command of the Roman forces "among the Celts".[8] What his precise title was is not definitely known,[9] though he may plausibly have been promoted by the emperor Valerian to the position of imperial legate of Lower Germany.[3][10] Postumus was evidently in favour at court, and, according to König, was granted an honorary consulship.[11] By 259, Valerian was campaigning in the east against the Persians, while his son and co-emperor Gallienus was preoccupied with the situation on the Danubian frontier.[12] Consequently, Gallienus left his son, Saloninus, and military commanders, including Postumus, to protect the Rhine.[13] Amid the chaos of an invasion by the Alamanni and Franks, and spurred on by news of the defeat and capture of Valerian,[12] the army in Gaul revolted and proclaimed Postumus emperor.[14][15][16] The trigger was their defeat in 260[note 1] of a Juthungian army which was returning from Italy laden with prisoners, even though they had been repulsed by Gallienus at Mediolanum.[14] Under the command of Postumus and Marcus Simplicinius Genialis, the Roman army crushed the Juthungi, and Postumus proceeded to distribute the captured spoils to the legions he commanded.[10] Saloninus, on the advice of his praetorian prefect Silvanus (who had coordinated Roman policy in Gaul alongside Postumus), demanded the transfer of the recovered booty to his residence at Colonia Claudia Ara Agrippinensium (Cologne).[13] Postumus assembled his army and made a show of reluctantly enforcing this command, thus inviting his troops to instead throw off their allegiance to Gallienus.[16] The troops accordingly proclaimed Postumus emperor and proceeded to besiege and attack Colonia Claudia Ara Agrippinensium, trapping Saloninus and Silvanus.[10] After breaching the walls of the city, Postumus had Silvanus and Saloninus killed,[10][16] although his supporters later claimed that it was the native Gauls who were responsible for the murders.[17] Later he erected a triumphal arch to celebrate his victory. Establishment of a Gallic empire[edit] Postumus aureus, 268, Treves, gold 7.40g. Postumus was immediately recognized as emperor in Gaul (except perhaps for Narbonensis[10]), the two Germanias,[17] and Raetia.[13] By 261, Britannia, Gallia Narbonensis and Hispania had also acknowledged him as emperor,[17] possibly after an expedition to Britain in the winter of 260/261.[18] He established his capital in northern Gaul, probably at Colonia Claudia Ara Agrippinensium[17] or Augusta Treverorum,[19] and then proceeded to set up many of the traditional Roman legislative and executive structures.[20] Apart from the position of emperor, he immediately assumed the office of consul alongside a colleague, Honoratianus.[2] Like his imperial predecessors, he became the pontifex maximus of the state[2] and assumed tribunician power each year.[20] He is thought to have established a senate,[13][15] perhaps on the basis of the Council of the Three Gauls or provincial councils,[21] and a praetorian guard,[17] one of whose officers was to become the future Gallic emperor Victorinus.[22] Reflecting his power base, the chief members of Postumus’ administration appeared to have been of northern Gallic origin, and indeed, the entire administration soon became rapidly Gallicized.[23] Both Victorinus and Tetricus, important members of the government, hailed from this region.[23] Postumus represented himself as the restorer of Gaul (Restitutor Galliarum) and the bringer of security to the provinces (Salus Provinciarum) on some of his coins;[17] prior to 10 December 261,[note 1] he also took the title of Germanicus maximus, a title he earned after successfully defending Gaul against the Germans.[13] His principal objective in assuming the purple appeared to be the restoration and defence of the Rhine frontier and the surrounding area, a task that he approached with vigour, earning the admiration of the ancient authors, who declared that he restored the security that the provinces had enjoyed in the past.[17] So successful was he in the task of restoring peace and security to the provinces under his direct control that the coins issued by Postumus were of better workmanship and higher precious metal content than coins issued by Gallienus;[24] his control of the Spanish and British mining regions was presumably crucial in this regard,[25] as was his employment of master minters who would have come into Gaul with Gallienus.[26] Postumus fought successful campaigns against the Franks and Alamanni in 262 and 263; following his victory over them in 263, he assumed the title Germanicus Maximus, after which his coin-types celebrated peaceful themes such as Felicitas Augusti for some time.[27] After having spent much of the last four years pushing the Franks out of Gaul, Postumus then recruited Frankish troops to fight against other Franks, probably dispersed within existing Roman army units.[28] Scholars continue to debate whether Postumus originally intended to dislodge Gallienus from Rome or was content to rule only the western provinces.[17] From the beginning of his usurpation, Postumus had made it clear that he had no immediate intentions to make a bid for Rome, that his priority was for Gaul.[13][16] Postumus’ powerbase was Gaul and his main responsibility was the defense of the Rhine provinces. If he marched against Gallienus, then he would be exposing his heartland not only to the Germanic tribes but also potentially to any number of usurpers.[17] Perhaps he hoped to achieve some official recognition from Gallienus; what is clear, however, is that Postumus was not overtly separatist and did not revive the 1st-century dream of an independent Galliarum imperium.[13] (See Julius Sabinus and revolt of the Batavi.) The forms, titles, and administrative structures of Postumus’ principate remained conventionally Roman.[29] Confrontation with Gallienus[edit] Coin of the Emperor Gallienus, from whom Postumus usurped power. For four years Gallienus had been too distracted by Germanic invasions and other usurpers in the east to turn his attention to the situation to his north and west.[30] This changed in 265 when Gallienus launched a campaign to defeat Postumus.[30][31] After some initial success against Postumus, his first attempt failed when Postumus managed to escape from a precarious situation due to the carelessness of Gallienus’ cavalry commander Aureolus,[13] leading to Aureolus’ demotion and eventual abandonment of Gallienus in 267.[31][32] A second campaign, led by Gallienus himself, also seemed to have the advantage over Postumus, but while Gallienus was besieging a city in Gaul (perhaps Augusta Treverorum[31]), he was wounded and forced to withdraw.[30][33] After his failed attempt at defeating Postumus, Gallienus was occupied with crises in the rest of his empire and did not confront Postumus again.[13] Gallienus nevertheless did manage to wrest control of Raetia from Postumus during these years.[31][dubious – discuss] Final years[edit] By the end of 265, Postumus’ coin issues were triumphantly commemorating the victory over Gallienus, and the festivities celebrating his quinquennalia continued into the following year.[13] Very little troubled the reign of Postumus from 265 to 268; archaeological evidence, such as it is, points to a general return to peace and normalcy.[34] In 266, Postumus became consul for the fourth time, taking as his colleague Marcus Piavonius Victorinus, a Gallic noble who was also a senior military officer; his selection to such a high-profile position may be seen as an attempt to broaden Postumus’ base of support.[35] The year 268 saw the issuing of the ‘Labours of Hercules’ series of gold coins in honour of Postumus’ favourite god.[36] A sudden debasement of the coinage later that year shows that Postumus was facing increasing financial difficulties, due perhaps to a disruption of silver production in the Spanish mines[37] or the need to buy off an increasingly discontented army.[13] Such discontent must probably have been due to the army’s frustration with Postumus’ failure to take advantage of a golden opportunity to move against Gallienus in 268.[38] Aureolus, the general who was in command of Mediolanum in Gallienus’ interest, rebelled and ultimately declared for Postumus.[30] The city of Mediolanum and its north Italian and Raetian hinterland would have been critical to Postumus if he planned to march on Rome. For whatever reason, Postumus failed to support Aureolus, who was besieged by Gallienus.[32][39] Before the end of the northern summer in 268, the events at Mediolanum were to see the assassination of Gallienus, the defeat of Aureolus, and the accession of Claudius II.[40] It also triggered a sequence of events that would see the end of Postumus’ rule in Gaul. Fall[edit] Aureus of Postumus, within a pendant Postumus assumed his fifth consulship on 1 January 269,[13] but the army in Germania Superior raised a usurper in early 269.[13] Laelianus, one of Postumus’ top military leaders and the governor of Germania Superior, was declared emperor in Mogontiacum by the local garrison and surrounding troops (Legio XXII Primigenia).[13][41] Although Postumus was able to capture Mogontiacum and kill Laelianus within a few months, he was unable to control his own troops, who wished to put Mogontiacum to the sack. When Postumus tried to restrain them, his men turned on him and killed him.[13][32][42] The mutineers set up Marius, a common soldier, as emperor. Marius held sway for a short while before being overthrown by Victorinus, Postumus’ erstwhile colleague in the consulship and tribune of the praetorian guard.[43] In the meantime, the Gallic Empire lost Spain.[44] Coinage[edit] A Radiate of Postumus Postumus has been of particular interest to numismatists, in light of the high quality and relative abundance of his coin issues. His ‘Labours of Hercules’ series is particularly renowned.[5] Notes[edit] ^ Jump up to: a b c d The year of Postumus' accession was either 259 or 260. In the past, the year 259 was favoured; today, however, most scholars consider that the summer or fall of 260 is the more likely date that he was hailed emperor, according to Polfer (Postumus) and J.F. Drinkwater (1987), p. 97. The terminus ante quem is an inscription from September 260 naming Postumus as emperor: Bakker (1993), pp. 369–386. Other dates cited in this article must be pushed back one year for those who take 259 as the year of Postumus' accession. See Drinkwater (1987), pp. 95-106. Jump up ^ Based on numismatic evidence, Postumus' rule extended over ten periods of tribunician power, each conventionally lasting for one year beginning on December 10. Regardless of which year Postumus assumed the purple (259 or 260), his rule must have stretched across ten such years. See Drinkwater (1987), pp. 93, 95.
