Commodus the Roman Emperor

Commodus – the Outrageous Emperor who Fought as a Gladiator

(Read the article on one page)

Roman Emperor Lucius Aurelius Commodus was a corrupt ruler who was not well received by the Roman people during his reign. He believed himself to be a reincarnation of Hercules, and enjoyed fighting in an arena as a gladiator. His outrageous tactics, such as slaying the crippled and slaughtering wild beasts in the arena, brought much negative attention, and were believed to have played a role in his eventual assassination. His tumultuous reign as Emperor was the starting point for a period of Roman history that is viewed as having been filled with chaos and decline.

Commodus was born on August 31, 161 AD in Lanuvium, 14 miles southeast of Rome. His father was Roman Emperor Marcus Aurelius, and his mother was Faustina the Younger. Faustina was the daughter of Roman Emperor Antoninus Pius, and was Aurelius’ first cousin. Commodus was the tenth of fourteen children born to Aurelius, and was ultimately the only surviving son.  His twin brother, Titus Aurelius Fulvus Antonius, died at age four.

Aurelius’ physician, Galen, was tasked with looking after Commodus to ensure that he stayed healthy and well. Every illness was treated to ensure he remained strong and hale. From all angles, Commodus was groomed to succeed the throne. In addition to Galen’s medical attention and treatment, Commodus was also highly educated intellectually, with little focus on military training. According to Aurelius, Commodus received his educational training with "an abundance of good masters."

Aurelius pushed for Commodus to be a leader from a very young age. It is of particular interest that Aurelius so craved succession by one of his sons, as there hadn’t been an Emperor who had been succeeded by his own son since Titus succeeded Vespasian in 79. It appears that Aurelius was desperate to have a son of his own bloodline succeed him. Aurelius himself, and the four Emperors that had preceded him, had all been adopted. In 166, at the age of five, Commodus was made Caesar, along with his younger brother Marcus Annius Verus. (It was three years later that Verus died, leaving Commodus as the only surviving son). Bestowing the imperial title of Caesar upon Commodus at such a young age further shows Aurelius’ desperation for Commodus to be viewed and treated as royalty.

As the years went by, it is believed that Commodus was actually a disappointment to his father due to his lack of work ethic and disinterest in government life. To some, this was a sign that Commodus was not actually the biological child of Aurelius, and that his mother had conceived him while engaging in an affair. This rumor was further fueled by Commodus’ love for engaging in gladiator battles as an adult, which led to speculation that his father was indeed a gladiator with whom Faustina had an affair.

Disappointment aside, Aurelius continued to promote Commodus through the ranks. Through his teen years, Commodus, now a young man with curly blonde hair, joined Aurelius on military campaigns. On November 27, 176, Aurelius promoted 15-year old Commodus to the rank of Imperator, which some say is a role similar to commander. The following year, Commodus became Aurelius’ co-Emperor, and they reigned together from then until Aurelius’ death in 180. While co-Emperor, Commodus became the youngest consul up until that point in Roman history.


Upon his father’s death in 180, Commodus became the sole Emperor. He is viewed as having been an inept Emperor, his megalomaniac tendencies leading to odd behaviors which frustrated and upset the Roman people. It appeared that he had no interest in being a leader, and only wanted to take advantage of his leadership powers to fulfill his own wants and desires.

Commodus did initially engage in some leadership-oriented activities, although not always in the favor of the Roman people. He negotiated a peace settlement in Rome’s favor. He also devalued Roman currency, reducing the weight of the denarius and reducing the purity of silver. But it didn’t take long for him to delegate his leadership responsibilities to others so that he could engage in activities in which he enjoyed. In the famous words of noted historian Dio Cassius, Commodus’s lack of interest in political affairs was the starting point for the decline of the Roman Empire, leaving Commodus responsible for initiating Rome’s decline "from a kingdom of gold to one of iron and rust."

Good article Reese.  As I recall didn’t his father also fancy himself a gladiator? (Marcus Aurelius)


It's ironic that we watched the film Gladiator the other night. While the true story behind his reign and death are fascinating, I prefer the fictional story, where he is killed in the arena before thousands of subjects by a gladiator whose family was ordered killed by the emperor.

Did you realise that "Gladiator" was a revamp of the 1960's movie "THE FALL OF THE ROMAN EMPIRE" starring Sir Alec Guiness, Sophia Loren, Christopher Plummer, Steven Boyd and Omar Sharif?

Strange that they didn't kill him earlier.

The Langeid Viking Battle Axe: The original and the copy.
Contrary to what many believe, battle axes from the last part of the Viking age, i.e. the 11th century, had evolved to become light, streamlined, and well-balanced. At the same time, they were powerful lethal weapons, something the recently reconstructed broad axe from Langeid in Southern Norway confirms.
