Maximinus Thrax

• 1. Introduction

  ›

  Maximinus Thrax became Roman emperor in 235 without ever having sat in the Senate, without ever having governed a province, and without any of the social credentials Rome's ruling class considered essential. He rose from what ancient sources describe as a life of shepherding and banditry to command legions along the Rhine. The Praetorian Guard acclaimed him; the Senate confirmed the choice, though with evident displeasure at having a man they regarded as a barbarian in the purple.

  His full name was Gaius Julius Verus Maximinus, and he was born around 173, most likely in Moesia. His origins were so foreign to Roman aristocratic sensibilities that the Senate could not quite believe someone like him was real. His physical size became legend. His cruelty, at least as his enemies told it, became the justification for a rebellion that would end his life. And the year he came to power, 235, would later be identified as the opening of the Crisis of the Third Century, a half-century of war and instability that nearly dissolved the empire entirely.

• 2. Where He Came From

  ›

  Herodian, the only contemporary historian who wrote about Maximinus, describes him as being of Thraco-Roman origin. The later and far less reliable Historia Augusta goes further, claiming his father was Gothic and his mother Alanic. The British historian Ronald Syme dismissed the Gothic claim outright, writing that the use of the word "Gothia" should have been enough to condemn the passage, since the Goths are not attested in the Danubian region until after Maximinus had already died.

  Syme, drawing on Herodian and the chronicler Syncellus, argued the evidence points toward Moesia Superior or Moesia Inferior as his homeland. Scholar Bernard Bachrach, however, does not accept that the anachronistic terminology alone should discredit the Historia Augusta's account. He argues the names it gives for Maximinus' parents are legitimate Alan and Gothic appellations, suggesting the author may have updated older, authentic source material with terminology current in his own day. What that leaves is an ancestry that remains genuinely contested.

  The name Gaius Julius, which Maximinus carried, offers a small clue. Roman practice held that freedmen and newly integrated citizens typically adopted the names of their former masters. The "Gaius Julius" combination suggests his family received citizenship during the Julio-Claudian era. Whatever his precise origins, he was categorically a provincial of low birth. He joined the Roman army during the reign of Septimius Severus and would not stop climbing until there was nowhere higher to go.

• 3. A Soldier Becomes Emperor

  ›

  Maximinus was the commander of the Legio IV Italica when Emperor Severus Alexander was killed. The troops who did the killing included the Legio XXII Primigenia, and they were angry. Alexander had been making payments to the Alemanni and had been avoiding direct military confrontation, something his Pannonian soldiers found intolerable.

  The assassination happened at Moguntiacum, the city now called Mainz, in 235. Alexander died alongside his mother. Within the Pannonian army, the men who had just killed their emperor turned to the nearest alternative: Maximinus, their own commander. The Praetorian Guard followed, and then the Senate, reluctantly, gave its confirmation.

  This transition carried enormous consequences beyond the change of personnel. Maximinus was the first emperor who had come from neither the senatorial class nor the equestrian class. Historian Brent Shaw, noting that Maximinus had reportedly been a shepherd and bandit before his military career, observed that such a man, in other circumstances, might have become something like a crime lord instead. His ascent illustrated something larger happening in the empire: the military was becoming a route of social elevation that the old aristocratic hierarchies simply could not contain. His son Maximus became caesar upon the new emperor's accession.

• 4. Campaigns and Construction

  ›

  Maximinus moved quickly to secure the frontiers he now commanded. His first major campaign targeted the Alemanni, whom he defeated in a swamp in the Agri Decumates, though Roman casualties were heavy. Following that victory, he took the title Germanicus Maximus, elevated his son Maximus to the rank of princeps iuventutis, and deified his late wife Paulina.

  A second campaign may have pushed even deeper into Germanic territory, reaching a battle against a Germanic tribe beyond the Weser, identified as the Battle at the Harzhorn. After stabilizing the German frontier, he established a winter base at Sirmium in Pannonia and from there pressed campaigns against the Dacians and the Sarmatians through the winter of 235-236.

  The infrastructure of the empire also occupied his reign. In 2019, Israeli researchers translated a milestone found in the village of Moshav Ramot in the Golan Heights and identified Maximinus' name on it. The roads themselves predated him; the milestone points to a renovation project during his rule. Keeping those roads operational required money, and money required taxation. Maximinus doubled soldiers' pay, a decision that, combined with near-constant warfare, drove tax collectors toward violent methods and illegal seizures, pushing the governing class further away from the emperor who relied on them.

• 5. 238 and the Year of Six Emperors

  ›

  Early in 238, the province of Africa exploded into revolt. Landowners armed their workers and clients, marched them into Thysdrus, the city now called El Djem, killed the offending imperial official and his bodyguards, and proclaimed the elderly provincial governor Marcus Antonius Gordianus Sempronianus as Gordian I. His son became Gordian II. The Senate in Rome swiftly endorsed both men as joint Augusti and began rallying the provinces against Maximinus.

  The revolt collapsed almost immediately in Africa. The neighboring province of Numidia was governed by a man named Capelianus, who held a long-standing grievance against the Gordians and commanded the only legionary unit in the region, the III Augusta. Gordian II died in the fighting, and when Gordian I heard the news he hanged himself with his belt.

  The Senate was now in a desperate position. Having publicly backed the Gordians, the senators could not expect mercy from Maximinus. They elected two of their own, Pupienus and Balbinus, as co-emperors. The Roman public reacted badly to two patricians being installed without broader consultation, pelting the imperial procession with sticks and stones. Street fighting broke out among factions supporting the grandson of the original Gordian. The co-emperors compromised and named young Gordian III as caesar. The year 238 would become known as the Year of the Six Emperors.

• 6. The Siege That Ended Everything

  ›

  Maximinus had been at Sirmium when the Gordian revolt began and had immediately marched his army toward Rome. The city of Aquileia, however, shut its gates against him. What Maximinus expected to be a rapid advance turned into a siege, and the siege ground on.

  His troops ran short of food. Disaffection set in. In roughly May or June of 238, soldiers of the Legio II Parthica killed Maximinus in camp, along with his son and his chief ministers. The man who had marched on Rome never reached it. He had, in fact, never visited the capital during his entire reign.

  Pupienus and Balbinus became undisputed co-emperors after the assassination. Their partnership was short. The two men mistrusted each other deeply, and the Praetorian Guard killed them both, leaving Gordian III as the sole surviving emperor. The crisis that Maximinus' own rise had triggered in 235 was still working its way through the empire's institutions long after the man himself was gone.

• 7. The Giant in the Sources

  ›

  Ancient writers could not agree on much about Maximinus, but they agreed he was large. Herodian, who was his contemporary, wrote that Maximinus was of such frightening appearance and colossal size that there was no obvious comparison to be drawn with any of the best-trained Greek athletes or with the warrior elite of the barbarians.

  The Historia Augusta pushes further, claiming, with attribution to a figure named Cordus, that Maximinus stood eight feet and one finger tall, roughly 2.4 metres. Scholars note that Cordus is one of several authorities cited in the Historia Augusta who appear to be entirely fictitious, making this particular measurement immediately suspect.

  Ancient imagery depicts Maximinus with a prominent brow, nose, and jaw, features that some historians have identified as consistent with acromegaly. Other historians read the outsized descriptions differently, arguing that stories about his extraordinary height, excessive sweating, and superhuman strength served a rhetorical function. They reflect the stereotyped image of the barbarian, or the awe and unease that the figure of the soldier inspired in the civilian population, more than they capture an actual physical reality. Eusebius of Caesarea, writing about Christian matters, records that Maximinus ordered the leaders of the churches to be put to death, driven by hostility toward his predecessor Alexander's household. Other evidence suggests those persecutions of 235 were more local in scope than Eusebius implies, confined to specific provinces rather than directed from the emperor himself.
