The Mystery of Caligula: The “Psychopath” Who Ruled Rome with Fear and Fury


Emperor Caligula, also known as Gaius Caesar Augustus Germanicus, is one of the most notorious figures in Roman history. His reign was marked by extravagant spending, political scandals, and acts of extreme cruelty. Many historians have described him as a psychopath due to his erratic behavior and propensity for violence. However, there are also those who argue that Caligula’s reputation has been unfairly tarnished by biased historical accounts. In this article, we will examine the evidence surrounding Caligula’s mental state and behavior to determine whether he truly was a psychopath.

Life and Reign of Caligula: An Overview

Caligula was the third Roman emperor and is remembered for his brutal reign and infamous reputation as a madman. He was born in 12 AD as Gaius Julius Caesar, the grandson of the great Roman general and dictator Julius Caesar. He came to power in 37 AD after the assassination of his predecessor Tiberius, and at first, his reign seemed promising.

However, Caligula quickly became known for his erratic behavior and cruelty. He spent lavishly on his own pleasures and made questionable decisions that undermined the stability of the empire. He is said to have slept with his sisters and made his horse a consul. Some historians have even labeled him a psychopath. In this article, we attempt to explore the life and reign of Caligula in more detail, examining the evidence for his supposed madness and considering whether or not he truly deserves the label of psychopath.

We will rewind his formative years, including his upbringing, rise to power, and actions as emperor. We will also examine the historical context of his rule and the factors that may have contributed to his behavior. Additionally, we will look at modern diagnostic criteria for psychopathy and compare them to Caligula’s reported behavior to determine whether the label of “psychopath” is accurate.

The Early Life of Caligula

Caligula was born in AD 12 to Germanicus, a popular general, and Agrippina the Elder, a granddaughter of Emperor Augustus. He spent his early years with his parents and siblings, but his family fell out of favor with Emperor Tiberius and were exiled to various locations. Caligula spent several years in exile with his mother and brothers, and it is said that this experience had a profound impact on his personality.

Caligula had a privileged upbringing, spending most of his childhood with his father on military campaigns. However, his life took a tragic turn when his father died suddenly in AD 19, possibly due to poisoning. Caligula and his mother were banished by Emperor Tiberius, who saw them as a threat to his own power. Caligula spent six years in exile on the island of Capri, where he may have been subjected to sexual abuse by Tiberius.

Caligula’s Rise to Power

Caligula’s rise to power was unexpected and unprecedented. After Tiberius died in AD 37, Caligula was proclaimed emperor by the Praetorian Guard, a group of elite soldiers responsible for protecting the emperor. At first, Caligula was popular with the people of Rome, as he promised to restore the republic and end the corruption that had plagued the previous administration. However, it wasn’t long before his true character began to show.

After the assassination of Tiberius, the Praetorian Guard, who were responsible for guarding the emperor, proclaimed Caligula as the new emperor. Caligula was only 25 years old and had no political or military experience, making his ascension to the throne all the more surprising. His reign began with great promise and he pardoned political prisoners, recalled exiles, and abolished some unpopular taxes. However, he soon began to show signs of mental instability, displaying erratic behavior and megalomaniacal tendencies.

Caligula’s Actions as Emperor

During his reign, Caligula engaged in a number of bizarre and cruel behaviors. He ordered the assassination of political rivals and members of his own family, and reportedly had sexual relationships with his sisters. He also spent exorbitant amounts of money on lavish projects and declared himself a god, demanding that he be worshiped as such. His behavior became increasingly erratic as his reign went on, leading some to question his sanity.

Caligula’s reign was marked by extravagance, cruelty, and madness. He declared himself a god and demanded to be worshipped, even going so far as to have his image placed in temples alongside the gods of the Roman pantheon. He engaged in wild spending sprees, squandering the empire’s wealth on lavish parties, palaces, and monuments. He also ordered the execution of anyone who opposed him, including members of his own family.

Diagnosing Caligula: Was he a Psychopath?

Modern diagnostic criteria for psychopathy include traits such as impulsivity, lack of empathy, and a disregard for social norms. Caligula’s reported behavior certainly fits many of these criteria, but it is difficult to diagnose someone who lived two millennia ago. Additionally, some historians argue that Caligula’s behavior was a result of the pressures of ruling a vast empire, rather than a reflection of a mental illness.

Was he a Psychopath?: The term “psychopath” is not a diagnosis recognized by modern psychiatry, but some historians have used it to describe Caligula’s behavior. He displayed many of the classic traits associated with psychopathy, such as a lack of empathy, impulsivity, and a disregard for social norms. However, it is difficult to diagnose historical figures with modern psychiatric labels, and some argue that Caligula’s actions were a result of political maneuvering or the result of his absolute power as emperor rather than a true indication of psychopathy.


In the end, it is impossible to know for certain whether Caligula was truly a psychopath. What we do know is that his reign was marked by cruelty, extravagance, and a disregard for human life. Whether his behavior was a result of mental illness or simply the actions of a ruthless ruler is a matter of debate. However, his legacy serves as a cautionary tale about the dangers of absolute power and the importance of strong institutions to hold leaders accountable.
