Most people know at least a few key facts about Julius Caesar and his infamous assassination on the Ides of March. But as the Roman Republic crumbled with him and the Roman Empire rose in its place, the rulers that came after him were no less controversial. Extravagance, executions, and extreme religious persecution stand at the forefront of many Roman emperor’s legacies. And that’s not mentioning the sex scandals.
So here’s a list of the absolute worst Roman emperors, in order from the mildly incompetent to the devastatingly unstable.
Diocletian, 284-305 CE
Emperor Diocletian deserves some credit, as his rule marked the end of the Crisis of the Third Century. His governmental reforms are cited as being one of the main contributors to the Roman Empire’s longevity for the next millennium. Diocletian regained control over a wild military force, suppressed enemy threats along the Empire’s borders, and revised the tax system in a broken economy.
However, he’s also credited with one of the most brutal attempts to purge Christianity in history, which definitely resides in the “cons” column. Diocletian revoked the legal rights of Christians, trying to encourage his citizens back to a more traditional worship of the old Roman gods. He razed churches and destroyed religious scriptures, and went even further to prohibit Christian’s from even gathering to worship. After a suspicious fire within the imperial palace, Diocletian’s belief in a Christian conspiracy led to a spree of scourging, torture, and beheading.
In 305 CE, after becoming greatly weakened by a severe illness, Diocletian resigned from his rule, passing the torch to someone with the strength to bear the Empire’s burdens. The first person to willingly abdicate from the role, the former Emperor spent the rest of his days tending a vegetable garden—sounds like a pretty fulfilling retirement.
Elagabalus, 218-222 CE
Elagabalus became Emperor at the tender age of 14, kicking off a reign that would be known for sex scandals and religious controversy—not exactly the sort of things you expect from someone fresh out of puberty.
Emperor Elagabalus started out in life as a high priest serving the Syrian sun god he shared a name with. When he came to rule over Rome, his devotion to the god drove him to try and elevate him to the same status as Jupiter, a move which greatly displeased the Empire. He even insisted upon marrying a Vestal Virgin, Aquilia Severa, which was in direct opposition to not only Roman tradition, but to the law.
On the more salacious side, it’s said that Elagabalus prostituted himself throughout the palace. He was married to five different women, and took on countless lovers of all sexes. He sent servants out into the city to procure lovers for him, and even opened the imperial baths up to the public to enjoy the spectacle of watching others bathe.
Some historians say that Elagabalus might have been one of the first transgender historical figures, offering large amounts of money to any physician who would be able to successfully administer gender reassignment surgery. This was regarded as wholly scandalous by the people of Rome, casting him in a negative light he couldn’t hope to overcome.
Elagabalus’s general incompetence on the throne led to the devaluation of the Roman currency. Showing his immaturity further, he began appointing lovers to crucial political positions. So while history tends to be unfavorable towards him for his personal choices, it does seem likely that he was unfit as an emperor mostly due to the fact that he was a literal child.
The Emperor’s youth did him no favors in the end, however. At 18 years old, Elagabalus and his eccentric behavior were brought to an end by the Praetorian Guard. After Elagabalus stripped his cousin’s titles and wealth, the Guard, who much preferred said cousin, rebelled against Elagabalus, killing both him and his mother in the violence.
Tiberius, 13-37 CE
There were plenty of things that Emperor Tiberius did right. He avoided needless and financially draining military campaigns and instead relied heavily on diplomacy. He reinforced the borders of the Empire. He even kept the Empire’s treasury generously stocked.
However, Tiberius never really wanted to rule as emperor, and that was very apparent. He left many responsibilities to the Senate and was otherwise distant and reclusive. He left Rome in the middle of his reign—a decision widely regarded as the worst one he could possibly make—and opened himself up to a reputation fully up to interpretation.
Whether these claims are rooted in truth or based fully in fabrication is impossible to know at this point, but either way, Tiberius was hated enough to get tongues wagging with the most vicious of talk. During his stay on the island of Capri, Tiberius was accused of flinging people off of cliffs for minor slights and engaging in disturbing sexual acts with very young boys. While that doesn’t have very much to do with governing an empire, it’s pretty much the last thing you want out of a ruler.
Tiberius earned a reputation as a bloodthirsty emperor after a mess grew out of a man named Sejanus making a grab for power. Sejanus tried to set himself up as Tiberius’s next heir by assassinating Tiberius’s son. Tiberius, of course, called for the death of not only Sejanus, but of those who were associated with him—including his children.
It seems likely, too, that much of his bad reputation comes from his connection to Caligula, who you’ll hear much more of later.
Caracalla, 211-217 CE
For the first 13 years of his reign, Caracalla ruled as a co-emperor alongside first his father, Septimius Severus, and then his brother, Geta. In 211 CE, he had his brother assassinated by the loyal members of his Praetorian Guard. Not satisfied, Caracalla went a step further to slaughter most of his brother’s supporters as well. In a further act of insult, Caracalla removed Geta’s image from paintings, coins, and statues, struck him from record, and made it an actual crime to utter his name.
On top of being generally regarded as a tyrannical and cruel emperor, Caracalla wasn’t all that effective in other aspects of his rule. He put into effect an edict which declared all free inhabitants of the Empire to be official citizens… so he could collect taxes from a wider base of people. He depleted much of the Empire’s funds trying to keep his army happy and often engaged in ruthless and unnecessary military campaigns.
Caracalla had an obsession with Alexander the Great, and in a fit of erratic behavior went on to persecute those philosophers of the Aristotelian school based solely off the legend that Aristotle poisoned Alexander. His behavior only got worse when, after discovering a play mocking him in the city of Alexandria, he dispatched his troops to massacre, loot, and plunder the city.
In 217 AD, Caracalla was stabbed to death by a defected soldier—an almost ironic end, considering his adoration for his own army.
Maximinus Thrax, 235-238 CE
Emperor Maximinus Thrax was a very large man, and he was also largely hated. In direct contrast to Emperor Diocletian, he’s often considered to be the ruler who caused the Crisis of the Third Century. He brought Rome to near ruin with his exhaustive military campaigns, overextending his soldiers by dispatching them to multiple fronts at once.
His distrust and distaste for anyone apart from his army did him no favors and caused social instability. Maximinus even had members of his own family put to death. He was a man who preferred to rule by conquest rather than favor and became known for wrecking public property and setting fires to any village he passed through.
His short three-year rule ended in 238 CE, when members of the Imperial Roman army assassinated him alongside his son and advisors.
Nero, 54-68 CE
Nero’s 14-year reign had some significant successes, including the negotiation of peace with the Parthian Empire and the quelling of Boudica’s revolt. While the upper class considered him overly extravagant and undignified, the lower classes of Rome actually had a strong positive opinion towards their ruler. This was true despite the fact that some of his methods leaned toward tyrannical madness. Seeing as he was only 16 years old when he took the throne, that’s not all that surprising—adolescence is hard.
In the beginning of his reign, Nero’s rule was closely guided by his mother, Agrippina the Younger, much as she had orchestrated Nero’s rise as emperor. Agrippina married his great-uncle and previous emperor, Claudius, and arranged for Nero to marry his new stepsister, Octavia. By 59 CE, an unexplained falling out caused Nero to order his troops to have her killed. This wouldn’t be the last time he organized a death.
In 62 CE, Nero divorced Octavia, citing that she was incapable of producing an heir. When his subjects looked negatively at this decision, he had Octavia exiled. Not long after that—either to further change public opinion or to solidify his claim to the throne—he accused her of adultery and had her put to death. His second wife, Poppaea Sabina, died in 65 CE. Some writers of ancient times say that Nero was responsible for this death, too, though others disagree.
Nero’s legacy as a madman is most closely tied to the Great Fire of Rome in 64 CE, which completely destroyed three of Rome’s 14 districts, leaving another seven heavily damaged. Many myths surround the terrible tragedy which killed hundreds of citizens, including the dramatically evil story of Nero fiddling as Rome fell to ashes.
In actuality, the fiddle wasn’t even in existence at the time. While some classical sources cite that Nero was on the roof of his palace singing from “The Sack of Ilium,” others place him dozens of miles away from the flames.
While it’s impossible to know the truth of the fire’s origins, many people blamed Nero directly for the destruction. It was believed that he was intentionally making way for a new city aesthetic. Whether out of genuine belief or a desperate attempt at scapegoating, Nero blamed the fire on followers of the growing Christian religion.
Nero set out to cruelly persecute the Christians, implementing an array of creative tortures and deaths, including wrapping them in animal skins to be torn apart by dogs.
After that, Nero’s rule started to crumble. Reconstruction efforts had stretched the Roman currency thin, and Nero’s indecision in dealing with further revolts caused widespread instability. In 68, his Praetorian Guard renounced their loyalty and declared Nero an enemy of the people. In one last dramatic flair, Nero committed suicide before he could be executed.
Caligula, 37-41 CE
There aren’t many reliable surviving accounts of Caligula’s reign. Even if the myriad stories surrounding him are fabrications, he’d have to be pretty unpopular to generate that kind of libel in the first place.
To be fair, Caligula had a bit of a rough start in life. He was the sole survivor after his entire family perished either in imprisonment or directly at the hands of Emperor Tiberius. He was then taken in by the emperor and indulged in all of his worst whims, until Tiberius passed and Caligula took to the throne at 25 years old.
In the first six months of his rule, things actually went pretty well. He cut unfair taxes, recalled those sentenced to exile, and granted military bonuses to soldiers. However, after a strange illness overtook him, his recovery was shrouded in a madness that gave way to sadistic and perverse tendencies. He became known for uttering the phrase, “Remember that I have the right to do anything to anybody.”
Any perceived mockery from his subjects was met with the punishment of death. In fact, in his infinite paranoia, Caligula began sending those closest to him off to exile or death—including his adopted son. His cruelty led to him gaining a sense of satisfaction out of making parents watch as their children were killed.
His arrogance rose to new heights as he declared that he was an actual living god. Caligula even had the heads of statues of gods and goddesses replaced with his own.
Further accounts of his insanity include throwing an entire section of a gladiatorial audience into the arena to be eaten by beasts for his own amusement, planning to appoint his horse as a consul, and turning the palace into a veritable brothel.
Caligula was assassinated by the Praetorian Guard after only four years as emperor. The man was so hated by the Senate that they even rallied to have him erased from the record of Roman history. Thanks to this campaign, it remains unclear to this day what is fact and what is fiction in the Caligulan reign.
Commodus, 180-192 CE
Commodus was appointed as a co-ruler by his father, Emperor Marcus Aurelius, in 177 CE. Marcus Aurelius died in 180 CE, leaving his narcissistic and self-indulgent son as the sole Emperor of Rome.
Because Caligula couldn’t be the only one to have all the fun, Commodus also thought himself to be a god, referring to himself as Hercules reborn and forcing others to follow suit. He swanned around the city in lion skins and participated in gladiatorial events—an act in which was considered scandalous for a ruler to partake.
What’s worse: He often chose to compete against weak soldiers who were sickly or maimed from the war, sometimes tying two of them together to club them to death with a single strike. To add insult to the already grave injury, he also exorbitantly charged Rome for his arena appearances.
Commodus’s self-love knew no bounds. He changed the calendar months to reflect his own self-bestowed epithets. He shamelessly exiled and executed his wife and proudly kept a harem of hundreds. He forced his advisors to take the fall for political blunders and had entire families slaughtered on suspicion of conspiracy.
