In late autumn of 275, the Roman emperor rode his horse along a rough dirt road in Thrace. The trees on either side were shedding their leaves, and the air was cold. Behind him, tens of thousands of soldiers were taking their positions for what was supposed to be the greatest campaign of his reign: the reconquest of the East. A war against the Persian Empire would make him greater than Trajan.
His name was Aurelian. He had already crushed Queen Zenobia of Palmyra and dismantled the Gallic Empire. Rome called him Restorer of the World. Within ninety seconds, he would be dead.
He had not been born to power. Lucius Domitius Aurelianus was born around 214 in a farming village near Sirmium, in what is now Serbia. According to the sources, his father was a tenant farmer. Aurelian grew up doing rural manual labor, plowing fields and hauling goods, learning the hardship of hard work in a corner of the empire most senators in Rome could not have located on a map.
At birth, he was a man of no account. Yet by 275, he had achieved what no one could have imagined. When he took the throne in 270, the Roman Empire had effectively split into three parts: the breakaway Gallic Empire in the west, the Palmyrene Empire in the east under Queen Zenobia, and a diminished Roman core in the middle, bleeding from every border. Within five years, Aurelian crushed both breakaway states and rebuilt the empire with his own hands.
That is why they called him Restorer of the World. But there was no such thing as a free restoration. Aurelian rebuilt Rome the same way he had built his career: through a discipline that terrified people. He executed officers for corruption.
He executed officers for personal crimes committed off the battlefield. His army had never been more effective. And his officers had never been more afraid. He seemed not to realize that these two facts would eventually collide.
The officers around him, the men who would ultimately kill him, were not villains. Most came from provinces like his own: Balkan boys, Danube boys, men who had risen through the same brutal military hierarchy, fought under him at Palmyra and Châlons, and watched their colleagues led away in chains for real or imagined crimes. They knew the emperor’s temper. They knew the fate of men who lost his trust.
In early 275, Aurelian announced his next war. The Sasanian Persians in the east were moving toward direct confrontation, and Aurelian intended to settle the matter as he had settled every other. He began assembling a field army in the Balkans, gathering legions, cavalry, and staff officers in Thrace. Somewhere among the paperwork of that mobilization, in the offices where scribes recorded his orders, one man was gripped by terror.
The army was not small. Modern estimates place its strength between thirty and sixty thousand soldiers: a mix of rebuilt field legions, cavalry units, and the personal guard that accompanied the emperor wherever he went. Each legion had a nominal strength of five thousand men, though most were understrength after decades of civil war and frontier attrition. Around this military core moved the staff: secretaries, quartermasters, couriers, notaries, the paper-pushing machines that turned the emperor’s words into imperial law.
Thrace itself was a country of hills, forests, and rough roads. The Roman military roads that crossed the region were paved near the main cities and dirt tracks everywhere else, dusty in dry weather, sticky mud in rain. In autumn, the days grew short and the nights cold. The villages were small, and the distances between them long.
It was the kind of country where a traveling emperor could easily find himself briefly separated from most of his guard. Aurelian ran that army the way he ran everything. He punished small failures the way other emperors punished treason. The Historia Augusta, our main narrative source for his reign, captures the man in one biting line: he was so strict in his discipline that many feared his anger more than they feared the weapons of the enemy.
His own officers feared him more than they feared the Sasanian army they were about to face. This is the atmosphere in which everything else unfolds. That brings us to a man whose name we cannot even be sure of. The sources call him Eros.
Other accounts call him Mucapor. What we know is his job. He was a notarius, an imperial secretary. He worked with documents.
He drafted correspondence. He kept records. He was part of the imperial machine, a small cog, and he appears to have made a mistake. We do not know what the mistake was.
The sources hint at some kind of irregularity, incompetence, or corruption. Perhaps a financial error, an administrative slip, or perhaps nothing more than a rumor that reached the wrong ears. Whatever it was, Eros became convinced that Aurelian had noticed, and he knew what being noticed meant. He knew what happened to notaries who angered the Restorer of the World.
This man, this frightened secretary, was not a soldier. He had never killed anyone. And he would not kill anyone now, not with his own hands. Sitting in his tent with his pen in his fingers and a wax tablet on his knee, he was about to devise a way to kill the most powerful man in the Western world using only ink.
He weighed his options. He could confess, prostrate himself at the emperor’s feet, and beg for mercy. But Aurelian was not known for mercy. He could flee, slip out of camp and vanish into a distant province.
But deserters were caught and severely punished. He could confide in a patron, a high officer, a friend at court, hoping someone would intercede. But which of the great would risk his position for a frightened clerk? Or he could use the tools of his trade and turn them into a weapon.
He could write a list of names of the emperor’s senior staff officers, influential men Aurelian relied upon, and present it as a death list, a document showing that these men were to be executed. The logic was brutally elegant. If he showed the list to the officers named in it, they would panic. They would not conduct a calm investigation.
They would not politely ask the emperor. They would act, because that is what frightened men do in dangerous situations. And by acting, they would destroy Aurelian, or destroy themselves, or destroy one another. Any outcome would draw attention away from Eros.
Whether this scene happened exactly as described, whether there was one lamp or two, whether the deliberations took an evening or a week, historians have debated for centuries. The Historia Augusta is not a reliable text, but the emotional truth of that moment is beyond dispute. Somewhere in a Roman camp in Thrace in the autumn of 275, a small, terrified man made the decision that would end the greatest generation of the empire. The dagger that killed Aurelian was, in truth, forged in an inkwell.
The list, when completed, was not a long document. The ancient sources do not tell us exactly how many names it contained, but it was enough. Senior officers, lawyers, men of rank and influence, men whose deaths were plausible because the deaths of senior officers were always plausible in Aurelian’s court. Eros formatted the document correctly, making it look like an imperial memorandum, and then began circulating it carefully.
Perhaps he showed the list to one officer in secret, presenting it as a warning from a friend inside the bureaucracy. Perhaps that officer showed it to another. Perhaps Eros made multiple approaches. However it spread, the list spread quickly, because a document like that does not stay in a drawer.
A man who has just seen his name on a death list does not stand idle. He looks for allies. He looks for options. For the men named on the list, the experience must have been a blow to the chest.
These were men who had served Aurelian loyally for years, who had risked their lives in his campaigns, who had watched him lead the column. And now they were told, apparently with the emperor’s own authority, that he had decided to kill them. The Historia Augusta makes it explicit: one of Aurelian’s secretaries, fearing punishment, wrote a list of names of certain officers as if they were to be executed, and showed it to those named. And so they killed Aurelian, believing he had ordered their execution.
The most effective ruler Rome had produced in half a century was targeted for death. Not because anyone wanted him dead, not because a political faction was rising against him, not because a foreign power had bribed his household. He was targeted because a middle-aged bureaucrat forged a document out of nothing but his own fear. The entire machinery, ink on parchment, was a lie convincing enough that it did not need to be true in order to kill.
What followed was necessarily quiet. Conspiracy inside a Roman military camp is not something announced aloud. The officers who felt targeted began meeting in small groups: a shared tent for wine, a walk together outside the perimeter, quiet conversation while inspecting horses. They exchanged information.
They confirmed that each of them had seen the same document or heard of it. They reviewed their recent behavior, anything that might have angered the emperor. Then they reached the same question. What do we do?
They could confront the emperor, but Aurelian did not tolerate insubordination, and demanding to see an alleged execution order was insubordination. They could try to reach the Senate in Rome, hundreds of miles away, but by the time any message arrived, they would be in chains. They could flee, but where does a Roman commander flee in a country controlled personally by the emperor? They could fight.
That was the fourth option. That is what they chose. Aurelian spent his days unaware. He inspected units.
He reviewed reports. He met with Persian envoys. He rode his horse. He ate.
He slept. By all accounts, he was entirely focused on the coming campaign, on the eastern war that would cement his reputation for a thousand years. He had been emperor for five years. He had survived Palmyra.
He had survived Gaul. He had survived Germanic invasions and internal plots. He was not looking back. The greatest threat to Aurelian’s life was not the Sasanian army he was about to face, nor a Germanic tribe gathering on the Danube, nor even a rival general in the provinces.
It was five or six men sitting at his own table, men whose names we mostly do not remember. The conspirators, whatever their number, needed a moment. They needed Aurelian in a place where his guards were few, where the terrain limited response time, and where witnesses could be controlled. This was not impossible during a march.
Traveling emperors were constantly surrounded by their entourage, but the entourage was the conspiracy. The personal guard was sometimes heavier than at other times, and the roads narrowed, and the columns spread out. Sooner or later, there would come a stretch of road where the man could be caught alone with his closest associates. They chose the pugio, the short, wide-bladed Roman military dagger, not the sword.
A sword drawn on the road in broad daylight in front of the emperor was an alarm before it was a wound. Any officer could wear a pugio openly without attracting comment. It could be drawn from under a cloak in one motion. It was the same weapon historians repeatedly noted that the conspirators against Julius Caesar had used more than three centuries earlier.
The greatest unifier of Rome would die by the same blade that killed her greatest general. Somewhere in Thrace, on an autumn morning that no one in the ancient world recorded with precision, the campaign column began to move. Aurelian mounted his horse and took his position at the head of the march. His officers took their places around him.
The same officers who had agreed last night on what they would do. They had daggers under their cloaks. They had a plan. And the emperor, riding in their midst, was thinking about Persia.
He had no idea that the next hour of his life would be his last. The road passed through open country dotted with rows of trees. It was not one of the empire’s main paved arteries. It was a secondary military road: stretches of dirt, gravel, and stones wide enough for a cart, narrow enough that cavalry units had to string out in single file or double file at certain points.
The columns moved with the usual noise of a Roman army on the march: the rhythm of boots on dirt, the creak of stiffened leather, the light clatter of metal fittings, orders shouted from time to time and passed down the ranks. Somewhere in the rear, mules and wagons. Somewhere in the rear, the main body of the legion marching in disciplined blocks. The conspirators were close.
That was the point. On the march, the emperor’s senior officers rode with him. It was their job. They were his staff, his link to the army, his voice.
Their presence beside him was expected. Their proximity drew no attention. Their hands resting near their belts drew no attention. The sources are frustratingly vague on details.
They only record that Aurelian was killed on the road in Thrace while on the march, not far from Byzantium in some accounts. We do not know whether there was a city on the horizon, whether it was raining, whether it was morning or evening. All we know is that a moment came, and when it came, everything ended in less than two minutes. The signal, if there was one, must have been something simple.
A nod. A word about routine business. A hand moving toward the emperor’s stirrup, as if pointing at something on the road ahead. Aurelian would have turned in his saddle.
He would have looked at the man addressing him. That was the moment. The first pugio struck fast. A short blade in a strong hand, driven upward under the ribs into the belly or across the chest.
Roman military daggers were not elegant. They were designed to kill men wearing armor at close range with brute force. Even a single well-placed pugio strike was often fatal. But there was not one strike.
There were several. That was the plan. Multiple conspirators striking at the same moment, so that if the first missed or was blocked or hesitated, the second, third, and fourth would not. Aurelian was sixty-one years old.
He was strong. The sources describe him as possessing tremendous physical strength even in his later years, but he was not armored for combat. He was riding his horse, not fighting. He had no shield.
He had no time. The men stabbing Aurelian with daggers were men whose faces he had known for years. Men he had promoted. Men whose careers he had made.
There was no surprise on their faces. They had rehearsed this scene in their minds hundreds of times over the past week. He fell from his horse or was pulled to the ground. He landed on the dirt of the road.
The strikes continued for a few more seconds to make sure, and then there was silence. Word spread through the column the way news of disaster always spreads, in contradictory fragments. The emperor is dead. The emperor is wounded.
The emperor was attacked by bandits. The emperor was killed by his own men. Which is true? No one knows.
Everyone is asking. Imagine the scene: between thirty and sixty thousand Roman soldiers, who had marched hundreds of miles on foot to fight a war against Persia, woke up over the next few hours to find that their emperor was dead, that the war they had been preparing for was now uncertain, and that they did not know whom to obey. There was no successor in the camp. There was no clear plan.
There was a corpse lying on the road and rumors spreading. The immediate problem was practical. What now? The conspirators had removed the threat.
They believed they had saved their lives. But they had not planned for what happened next. Because most conspirators in most political assassinations throughout history do not plan for what happens next. They plan the killing.
The killing is the core idea. Everything after is improvisation. The news had to be sent. The Senate in Rome, hundreds of miles away, had to be informed.
Someone had to prepare the body, because whatever Aurelian had been, he was still Augustus, and the body of an Augustus was treated with special rites. Someone had to speak to the soldiers. Someone had to make sure the army did not dissolve into civil war within hours. The conspirators did what they could.
They spoke to the units they trusted. They promoted their version of events. They tried to control the narrative. But narratives are hard to control in a camp of tens of thousands of men, most of whom had loved their emperor with the particular love soldiers feel for a victorious commander.
And then the plan began to fail. Not spectacularly, not immediately, but quietly at the edges. Loyalist officers, men who had not been on the list, men who had not been part of the conspiracy, began asking questions. They wanted to see the document.
They wanted to see the execution list that supposedly forced this action. They wanted to know who had drafted it. They wanted to know who had signed it. This was the trap Eros had set for himself without meaning to.
The forged document, once it had served its purpose, did not disappear. It existed. It could be examined. It could be compared to other imperial documents.
It could be checked by men who had handled genuine orders from Aurelian for years. The list was still there, and it was still obviously fake. The loyalists began comparing information, and the story began to fall apart. Somewhere in the camp, a small, frightened, middle-aged bureaucrat named Eros, the man who had used his ink to do all of this, was beginning to understand exactly what he had done.
Nothing happens immediately in ancient history. Communications across the empire were far too slow. The Senate, hundreds of miles away in Rome, had to be informed, had to deliberate, had to produce a new emperor. This process took weeks.
After Aurelian’s death, the greatest empire in the Western world remained without an emperor for a period of time, running on its own momentum. The army in Thrace stood idle. The Persian campaign was halted. The eastern frontier that Aurelian had intended to settle himself was left to its fate.
During those weeks, the investigation into Aurelian’s death began. Officers were interrogated. Documents were gathered from the imperial archives. Witnesses among the staff were interviewed.
The famous list, the forged execution order, was produced and examined. It did not survive scrutiny. The Historia Augusta records the moment the truth came out: when it was discovered after his death that no order for execution existed, the emperor’s killers were seized with profound grief and were punished. Profound grief.
The men who killed Aurelian, experienced senior officers and professional soldiers, realized in the following days that they had killed their emperor for nothing, that the document which had compelled them was nothing but the panic of a clerk disguised as an imperial order. In that moment, everything changed. The killers turned from conspirators into criminals. News of the forgery spread among the officer corps the way the original list had spread: quietly, gradually, unstoppably.
The document was examined and found to be fake. There was no order. There had never been a death list. The emperor had not been planning to kill them.
The emperor had been planning to march east and defeat the Persians. Imagine being in that position. You have spent the past weeks believing you were about to be executed. You accepted that survival required committing the most terrible crime in the Roman moral order: killing the emperor.
You justified it to yourself. You convinced yourself you had no other choice. And then, within a few hours, you learn it was all fiction. You killed him for nothing.
Nothing at all. The sources, despite significant gaps elsewhere, are relatively clear on Eros’s fate. Once the forgery was traced back to him, his fate was sealed. Most likely, he was executed.
No record survives of the precise proceedings, the date, or the place. But the outcome was inevitable. He had used his ink and his hands to create a document that killed the emperor. There was no legal or political framework that would allow him to survive that discovery.
He had set a trap to save himself. He had walked into it first. He committed forgery because he believed he was going to be executed, fleeing from execution. In the end, he was executed anyway, for the very forgery he had committed.
The road he built to escape led him, by a longer and bloodier route, back to the destination he had been trying to avoid. We do not know the names of most of the officers who stabbed Aurelian. The sources refer to them by their titles rather than their names. But we can identify their category: senior officers, officials, men of standing.
In the months following the assassination, they began to disappear from the records one by one. Some were arrested and executed. Others may have died in the usual chaos of succession, in political violence, in personal feuds, in opportunistic killings. A few may have kept quiet, retired, or tried to survive by making themselves useful to whoever came next.
But even those men, who survived the immediate reckoning, never rose again. None of Aurelian’s killers gained lasting power. None of them became emperor. None of them profited.
Meanwhile, the Senate in Rome took its time. The vacancy stretched for weeks. Eventually, an elderly senator named Tacitus was elevated to the rank of emperor. A man in his seventies, chosen because he was respected, harmless, and unlikely to threaten anyone.
Under Tacitus, or in his name, the official machinery of punishment turned toward the conspirators. It was slow and uneven, but it was thorough enough to erase the names of Aurelian’s killers from the state history of Rome. So, to answer the question posed at the start: did the killers get away with it? No.
None of them did. The conspiracy that seemed, in the terror of its planning, like the only path to survival became a path to a different, slower death. Eros was killed. The officers who carried the daggers were killed or erased from history.
The Persian campaign was canceled. The eastern war that would have made Aurelian a legend among his contemporaries never happened. Everything they touched collapsed. Aurelian’s body, as far as we can determine, was treated with the honor due an emperor.
The precise details of his funeral rites are not preserved. He was most likely deified, the Roman practice of elevating deceased emperors to the ranks of the gods still being in force, and later emperors referred to him with formal respect. But the man himself, the tenant farmer’s son who rebuilt the world, was gone. Whatever plans he had held in his mind for the eastern frontier died with him on a Thracian road.
The assassination that was supposed to save five or six men from execution ended with all of them dead, a war canceled, an empire destabilized, and the strategic vision of one of the most effective rulers Rome ever produced erased. The conspirators thought they were solving a problem. In fact, they created every problem that followed. Aurelian’s death in the autumn of 275 did not end the Roman Empire in itself, but it removed the one man who could have settled the eastern question a generation before it was finally resolved, and it happened at a moment when the empire could not afford the loss.
Tacitus, the elderly senator elevated after the vacancy, reigned for less than a year before his death, perhaps from natural causes, perhaps not. The succession spiral of the third century continued. Other emperors fought the Persian war Aurelian had planned in later centuries at greater cost. Over the following centuries, the story of Aurelian’s assassination was simplified and repeated until it became a moral tale: the tyrant emperor destroyed by his own cruelty, the wicked secretary punished for his deception, the wheel of fortune turning.
That version is not entirely wrong, but it misses the details of what happened: how the terror of one small man, embodied in a sheet of paper, was enough to kill the man who had reunified the empire. Modern historians have increasingly emphasized, and most passing accounts still miss, that Aurelian’s assassination was not an anomaly. It was one murder among many in what scholars call the Crisis of the Third Century, a fifty-year period in which Roman emperors were assassinated so routinely that dying of natural causes was statistically rare. Aurelian was not killed because he was uniquely cruel or uniquely unlucky.
He was killed because the political system he inherited was structurally incapable of protecting the emperor from his own senior officers. The forged list was the spark. The system was the weapon. There is no monument in Thrace marking the place where he was killed.
No archaeological site has been identified. No local tradition preserves the exact road. What remains of Aurelian is elsewhere. The massive city walls he built around Rome, still standing today, are still called the Aurelian Walls.
His murder took place in an unnamed spot that history did not bother to remember precisely. Ironically, his achievements are the only part of him that still has an address. Back on that road in Thrace in the autumn of 275: the trees half bare, the air cold, the emperor riding at the head of a column, thinking about Persia. Around him, closing in slowly, men whose names we have almost forgotten, men who believed they were about to die, convinced by a sheet of paper written by a terrified clerk in a tent, and who decided that killing was the only way to save themselves.
They were wrong. Every one of them was wrong. Aurelian was killed because a small, frightened man with a pen and a lie was, at that particular moment, more dangerous than the entire Sasanian army. The killers thought they were saving themselves.
In truth, they were writing their own death warrants in a hand that had never been the emperor’s.
