There was a time in the history of Rome when the imperial throne became the most dangerous position in the world. A place where sitting down meant signing your own death warrant. In 50 years, more than 50 men tried to call themselves emperor. Some lasted months, others lasted weeks. Some did not even complete a single day with the crown on their heads before being killed by the same soldiers who had proclaimed them the day before.
Generals were rebelling in the provinces. Entire legions elected emperors out of thin air. And in Rome, the blood of one Caesar had barely dried on the palace floor when the next one was already being stabbed in the same place. What you are about to hear is the story of the 50 most chaotic, bloodiest, and most decisive years that Rome ever experienced.
Around the year 200 AD, the Roman Empire was, without exaggeration, the greatest political structure the West had ever built. Its borders stretched from Scotland to the Sahara. From the coasts of Portugal to Mesopotamia, it was almost 5 million square kilometers, more than 60 million inhabitants, one in four people alive on the planet living under the Roman eagles.
Paved roads connected cities for thousands of kilometers. Aqueducts carried drinking water to arid regions. The legions maintained order on the borders. Trade flourished, the laws worked, and the so-called Pax Romana had guaranteed more than two centuries of relative stability. It was a colossus that seemed to function on its own, like a perfectly calibrated machine.
And anyone alive at that time would have sworn that that empire would last forever. But behind that facade of grandeur, cracks were already spreading. The empire had grown too large. Each new province demanded more soldiers, more administrators, more money. The economy, based on large estates sustained by slave labor, began to falter when conquests stopped and the flow of new slaves decreased.
The fields produced less, prices rose, and the tax burden on small landowners increased year after year. Families who had cultivated their lands for generations were beginning to lose them to powerful lords who bought everything for pennies. And in the cities, a growing mass of unemployed people lived off public distributions of wheat and the generosity of games in the amphitheater.
The famous bread and circuses that kept the masses entertained while the system deteriorated from within. But the most dangerous problem of all was not on the borders or in the fields, it was inside the palaces themselves. Because Rome had never managed to resolve a fundamental issue. How to choose the next emperor? There was no clear rule of succession.
There was no constitution, no election, no stable mechanism to transfer power from one man to another. Everything depended on political adoptions, family intrigues, or increasingly, pure brute force. The Praetorian Guard, which had been created to protect the emperor, in practice became the group that decided who went up and who went down.
And the army, which since Marius’ reforms had ceased to be a citizen force and had become a professional machine loyal not to Rome, but to the general who paid its soldiers, was transformed into the true arbiter of power. The soldiers no longer fought for the Republic or the Senate. They fought for whoever promised them more money, more land, more rewards.
And it was precisely that flaw, that seemingly small crack in the heart of the system that in a few decades would transform the most powerful empire in the world into a nightmare of blood and anarchy. The trigger was pulled in the year 235 AD. Emperor Alexander Severus, the last of the dynasty that bore his name, was on the front lines of the ring trying to negotiate peace with the Germanic tribes that were pressing the Roman defenses.
Alejandro was young, educated, and influenced by his mother Julia Mamea, who accompanied him in practically all decisions. For his legionaries, that was unacceptable. An emperor who negotiated instead of fighting. An emperor who obeyed his mother instead of ruling alone. An emperor who preferred diplomacy to the sword.
On an ordinary morning, at a military camp on the side of the ring, a group of rebellious soldiers invaded the imperial tent and killed Alexander along with his mother. There was no trial, no warning, not even an attempt at explanation. They simply murdered him and proclaimed in his place a general of Trao origin named Maximinus, a brutal, enormous man, whom the sources describe as a giant over 2 meters tall, capable of breaking a horse’s jaw with a single blow and drinking 20 liters of wine in a single night.
Rome had a new emperor and the nightmare had begun. Maximino never bothered to visit Rome. He ruled from the frontiers, crushing Germanic tribes with a ferocity that frightened even his own officers. He confiscated property, brutally increased taxes, and melted down statues of gods in temples to mint coins and finance his campaigns.
But just 3 years later, the landowners of Africa, crushed by their taxes, rebelled and proclaimed their own emperor. And when Maximinus marched to crush him, his own soldiers, exhausted and hungry before the walls of a city that resisted the siege, decided it was time to change leaders once again. Maximino was murdered in his own store.
His head was cut off and sent to Rome, impaled on a spear. The giant’s reign had ended, and with it opened the gate that no one else would ever be able to close. From then on, what followed was 50 years of pure chaos. 50 years in which the imperial throne became the most unstable, most dangerous, and deadliest position in the known world.
Generals proclaimed themselves emperors in distant provinces. They would march against Rome with their legions, assassinate whoever was sitting on the throne, take their place, and weeks or months later, they themselves would be assassinated by the next ambitious general. It was a vicious cycle that fed on itself.
Each new emperor knew from day one that he would probably die a violent death, and that certainty made them even more brutal, even more paranoid, even more willing to eliminate any rival before the rival eliminated them first. The numbers are simply astounding. In just 49 years, between 235 and 284, more than 20 men officially occupied the imperial throne and at least twice as many tried.
Some lasted for years, others for months, others for weeks. Gordian I and Gordian II, father and son, were proclaimed emperors in Africa and both died within a month of each other. The father hanging himself upon learning of his son’s death in battle. Pupieño and Balvino, two respectable senators elected to govern together, lasted barely 99 days before being dragged from a banquet by the Praetorian Guard, tortured in the streets, and left naked and mutilated in the middle of Rome.
Emiliano lasted 88 days, Quintilo lasted perhaps 17. And there were dozens of others who proclaimed themselves in distant provinces. They minted their own coins, assembled their own armies, and tried their luck in the most dangerous game of the ancient world. The difference between a legitimate emperor and a usurper was only one: who survived longer.
In that nightmarish scenario, some figures managed to stand out, not because they lasted longer, but because of the magnitude of the disaster they faced. Emperor Decius, for example, who ascended the throne in 249, was the first Roman emperor to die in combat against a foreign enemy. It happened in 251 at the Battle of Abritus in the marshes of present-day Bulgaria, when his army was surrounded and destroyed by the Goths led by Kniva.
Deso and his son died swallowed by the swamps. Their bodies were never recovered, and the Roman army suffered one of the most humiliating defeats in its history. The Goths, who until then had been seen as peripheral barbarians, suddenly became an existential threat. And the borders of the Danube, which for centuries had held the barbarian world out, began to appear as a line drawn in the sand.
And while the generals were killing each other for the throne and the Goths were pushing from the north, who was paying the highest price? They were ordinary people. Civil wars did not happen on isolated battlefields. They crossed entire provinces, destroying cities, devastating crops, and looting villages.
The legions that once protected the borders now marched into the heart of the empire itself, fighting other Roman legions. Legion against legion, Roman against Roman. And on the abandoned borders, enemies from outside quickly realized that the giant was distracted. Franks and Alamanni invaded Gaul almost every year. Bands of Gothic pirates swept the coasts of the Black Sea and the Aewe, plundering cities that saw no enemy. Asia centuries.
And on more than one occasion, barbarian armies penetrated so deeply into Roman territory that they reached Italy itself, something that had not happened since the time of Hannibal, 500 years earlier. The population no longer knew who to fear, whether the barbarians who came from outside or the Roman soldiers who acted exactly like barbarians.
And on top of all this, as if civil wars and invasions weren’t enough, came the plague. Around 250 AD, a devastating epidemic swept across the empire from one end to the other. Historians call it the Plague of Cyprian, after the Christian bishop of Carthage, who described it in horrifying detail. Cipriano reported incessant vomiting, extremely high fevers, gangrene in the extremities, blindness in many survivors, and diarrhea so violent that the sick lost all their strength in a matter of hours.
Sources report 5,000 deaths per day in the city of Rome alone during the worst moments of the outbreak. Entire cities were emptied, military barracks were left without funding. The already scarce workforce disappeared. The fields were left without workers, the markets without goods, and hunger joined with disease to create a scenario of despair that seemed like the end of the world.
For many Christians whose numbers were growing during that period of suffering, it truly seemed like the fulfillment of biblical prophecies. The world they knew was crumbling before their eyes, and amid the horror, many Christian communities distinguished themselves by caring for the sick and burying the dead as everyone else rose up, gaining respect and converts at a rate that the empire itself could not ignore.
The economy, which had already been suffering for decades, went into total collapse during the crisis. The state, desperate for money to pay for the ever- increasing armies, began to adulterate coins with ever-increasing audacity. The silver denarius, which in the time of Augustus was made of almost pure silver, was progressively degraded until it contained less than 5% real silver, the rest being filled with copper and tin.
In practice, Rome was minting counterfeit money. Inflation soared to unprecedented levels . The price of a sack of wheat could double in a matter of weeks. Confidence in the monetary system disappeared completely. People reverted to bartering, directly exchanging goods for goods, as if centuries of economic civilization had simply never existed.
Merchants were abandoning the cities. The trade routes that once connected India, Africa and the interior of Europe. Rome was broken one by one. Pirates and bandits dominated the roads that were once safe. The empire was drowning in a silent hunger, not for food, but for money, for circulation, for economic oxygen.
And the small landowners, crushed by taxes and without protection against plunderers, began to seek refuge wherever they could, voluntarily surrendering themselves to large landowners in exchange for safety. It was the embryo of feudalism being born within Rome centuries before the Middle Ages officially began.
And it was in that scenario of total disintegration that the ultimate humiliation occurred. In 260 AD, Emperor Valerian, who ruled the eastern half of the empire, marched against the Sasanian Empire on the Mesopotamian frontier. The Persian king first waited patiently. The exact details of what happened are debated by historians. Some say it was a military defeat, others that it was a diplomatic trap, but the result was the same.
Valeriano was captured alive. A Roman emperor, the lord of half the civilized world, a prisoner of a foreign king. The reliefs sculpted at Nakhe Rostam, in Iran, show Zapori on horseback with Valerian kneeling before him and, in another version, using the Roman emperor as a step to mount his horse. Some traditions say that Valerian died in captivity and that his skin was torn off, dyed red, and displayed in a Persian temple as a trophy.
Never before in the history of Rome had an emperor been captured by the enemy, and the impact of that was devastating. With Valerian a prisoner in the east, the empire fragmented. His son Galliano tried to hold onto what remained of power from Rome, but it was like trying to hold water with your hands. In Gaul, a general named Postumus proclaimed himself emperor and founded what became known as the Gallic Empire, a separatist state that controlled Gaul, Britain, and Hispania with its own consuls, its own senators, and its own legions. In the East,
Queen Senovia of Palmyra, one of the most fascinating figures of antiquity, took advantage of the power vacuum to expand her own kingdom with an ambition that frightened the entire world. Senovia conquered Egypt, Syria and much of Asia Minor, ruling with intelligence, culture and an iron fist. He was said to be a descendant of Cleopatra, spoke several languages, married his generals, and defied Rome with a boldness that no man of that era had ever shown.
Suddenly, the empire that Augustus had unified was divided into three pieces. Three different emperors, ruling three different territories, each minting their own coins, maintaining their own armies, acting as if the other two simply did not exist. To contemporaries it seemed like the definitive end of Rome, but Rome was not yet dead.
Salvation, curiously, came not from Rome, but from a remote region of the Balkans called Illyria, which today comprises Croatia, Serbia, and Slovenia. From there emerged, in succession, the toughest and most competent generals that the empire had produced in decades. The first was Claudius Secundus, later called Claudius the Gothic, who in 268 assumed the throne and inflicted a crushing defeat on the Goths at the Battle of Naio in the Balkans, killing tens of thousands and breaking the offensive power of those barbarians for a whole generation. It was the
first major Roman victory in years and it restored to the army a spark of morale that had long since disappeared. Claudius died of plague two years later, proving that not even the saviors escaped the curses of that century. But his successor was even more extraordinary. Aureliano, another Illyrian, hard as iron and implacable as a leaf, assumed the throne and in a few years did what seemed impossible.
He defeated the barbarians who had invaded Italy, driving them beyond the Alps. He marched west and reconquered the Gallic Empire of Tetrico, the last successor of Postumus, who surrendered without much resistance. He then turned east and confronted Senovia of Palmyra, defeating its armies in Syria and besieging its capital until it surrendered.
Senovia was captured and taken to Rome in chains of gold, paraded in Aurelian’s triumph as living proof that the empire had been reunified. Aurelian won the title of restitutor orbis, the restorer of the world. And for a moment it seemed that Rome had finally found the man capable of ending the nightmare.
Aurelian also built a new defensive wall around Rome itself, enormous, imposing, almost 19 km long, which still stands today in several sections of the city. The mere fact that the capital of the world needed new defensive walls, something that had not happened since the Gallic invasion 800 years earlier, said everything about the true state of the empire.
But even Aurelian did not escape the curse of the third century. In 275 he was assassinated by a group of his own officers, the victim of a conspiracy based on a lie invented by a corrupt secretary who feared being punished for his frauds. The restorer of the world died in the same way as almost all his predecessors, stabbed in the back by those who should have protected him.
When the conspirators discovered that they had been manipulated and that Aureliano never planned to kill them, remorse gripped them all, but it was too late. It would be necessary to wait a few more years, until 284 AD, for the man who would finally end that nightmarish half-century to emerge. His name was Diocletian and he was another Illyrian general born into a humble family on the Dalmatian coast, perhaps the son of a freed slave.
Diocletian looked at the shattered empire and understood something that none of his predecessors had had the courage to admit. The empire was too large to be ruled by a single man. The solution he found was radical and unprecedented. He divided power into four, creating the tetrarchy system with two emperors called Augusti and two junior emperors called Caesars, each responsible for a part of the territory, each with his own army, his own capital, and his own area of action.
He reorganized the army from scratch, separating the border troops from the mobile rapid reaction troops. He reformed taxes, created a new currency, and tried to contain inflation with price-maximum edicts that threatened death to any merchant who charged above the rate. And for almost 20 years, with an iron fist and administrative intelligence, he managed to keep the machine running.
The crisis of the third century had officially ended. Rome had survived, but the price paid was incalculable. The empire that emerged from those 50 years of chaos was no longer the same one that had entered them. It was an empire militarized to the bone, bureaucratized to the point of paralysis, divided into halves that increasingly regarded each other as strangers.
The emperor was no longer the first citizen of the time of Augustus. He was an absolute monarch, surrounded by almost divine ceremony, dressed in purple and gold, wearing a diadem like the Eastern kings, separated from the people by layers of courtiers, guards and rituals that would make Cyrus of Persia feel right at home.
The old republican idea, that last echo of the Senate and the forum, had died on some forgotten battlefield between 235 and 284, without anyone bothering to bury it. Rome had survived the crisis, yes, but the Rome that emerged on the other side was something else entirely, and the world it would build from then on would be very different from the one Augustus had dreamed of.
And there is a lesson in that story that is perhaps worth more than all the names and dates we just went through . Because what the crisis of the third century teaches us is not only that Rome almost fell, but that no government, however large, however rich, however powerful, is safe from itself. The barbarians who crossed the borders were dangerous.
Yes. The plague that killed thousands was devastating. Yes. But the most deadly blow always came from within. It came from the greed of the generals, from the weakness of the institutions, from the corruption that infiltrates when no one is looking, from the illusion that power is eternal just because it has always existed.
Rome almost died not because its enemies were too strong, but because it forgot what had made it great.
