Top 11 Surprising and Fascinating Facts about the Roman Emperors

More than 150 sovereigns ruled over ancient Rome before the Western Empire fell; the Eastern Empire continued for a little longer. The first Roman emperor was Augustus Caesar in 27 BC, and the last was Romulus Augustulus whose reign ended in 476 AD. Roman sovereigns often took titles like “Augustus,” “Caesar,” and “Imperator” to stress their importance.

In 27 BC, Rome became a republic. This was brought about by Julius Caesar, and his son Octavian (Augustus) is generally considered to be the first Roman emperor. However, some historians believe that Julius Caesar himself was a sovereign as he was very powerful and had absolute control of the Senate.

Many of the rulers of ancient Rome contributed to the amazing progress and expansion of the state, while others such as Caligula and Nero brought abuse, fear, and chaos. Below is a list of the top 12 fascinating facts about these powerful leaders:

1. The Praetorian Guard

Praetorian Guard

The emperors used an elite military unit called the Praetorian Guard to protect them. Members of the guard were responsible for the safety of the emperor and his family, but they also had other roles such as policing mass gatherings and subduing rebellions.

The Praetorian Guard was a powerful political movement and often interfered in top-level politics. Praetorian prefects were high-level officials within the guard, and they often led the way in plots to overthrow the emperor. Some of these plots succeeded, as can be seen in Claudius’ rise to power in 41 AD following the destruction of Caligula. The prefects knew that they could expect to receive a generous reward for their support.

2. Challenges to the Emperor

The Battle of Lugdunum, also called the Battle of Lyons, was fought in 197 AD between Emperor Septimius Severus and Clodius Albinus, the administrative ruler of Roman Britain and a challenger to the emperor himself.

An estimated 300,000 Romans are said to have taken part in this battle, 75 percent of the total number of Roman soldiers in the whole of the empire at that time. The fight was evenly balanced, and eventually, Severus was triumphant – just.

3. From First to Last

The first and last Roman heads of state, at least in the west, were both called Augustus. The last emperor took the full name Romulus Augustulus, which was probably a reference to Romulus, one of the twins who is credited with the original foundation of the Roman state. Unfortunately, it became clear that simply naming yourself after a great figure from history wasn’t enough to hold the empire together.

4. Powers of the Emperor

A Roman emperor’s title Princeps Senatus meant that he was head of the Senate, presided over their sessions, guided their discussions, and set out their rules and standards. He had the power to hire and fire at will, call the Senate to session whenever he liked, and veto any of the Senate’s decisions. As Pontifex Maximus, the emperor was the religious leader, with total power over the vestal virgins. He also controlled the country’s finances.

5. Diocletian

Diocletian Roman Emperor

It might appear strange to include Emperor Diocletian in this list, since he is best known for the decision to separate the administration of Rome in two, appointing Marcus Aurelius Maximianus as co-ruler, each with a subordinate known as a caesar, in a four-way power split known as a tetrarchy. Overall, Diocletian was a decent ruler and able to keep his system of rule together when Rome was under pressure from external enemies. What gets Diocletian included here, however, is his completely savage treatment of Christians.

Christians had, for some time, been respected by most Romans and treated with a blend of dislike and tolerance, yet Diocletian embarked on the all-out annihilation of Christianity. Churches were demolished, sacred texts burnt, and Christian ministers arrested and forced to renounce their religion on pain of death. Christians who didn’t renounce were tormented and executed.

This behavior was truly bizarre as the Romans were usually very tolerant of different religions. It may have been an indication of Diocletian’s own insecurity and fear for survival; Christianity represented a departure from traditional Roman religious beliefs that he could not tolerate.

Diocletian was the first emperor to abdicate in an elaborate abdication ceremony, and this is thought to be due to ill health. He retired quietly to tend his vegetable garden.

6. The Antichrist

It was generally believed that even after his suicide, Nero lived on as the Antichrist. Many people believed that he would return, and the fact that his body was never found strengthened this conviction. After his death, there were no fewer than three men who professed to be the returned Nero. Christians were convinced that he was the Antichrist who would soon return from hell to torment them.

7. Tiberius

Tiberius Roman Emperor

Tiberius was the unlikely successor to Augustus, being an adopted son. Augustus did not expect Tiberius to succeed him, but it was fighting between the emperor’s grandsons Gaius and Lucius (whom Augustus had also adopted), and Augustus’ decision to expel their cousin, Agrippa Postumus, that placed Tiberius in line for succession.

Tiberius was a skilled military officer and member of the Senate. However, he had a suspicious and insecure nature which drove him to remove those whom he saw as a threat. As part of these purges, he exiled Agrippina, the widow of his nephew, the war hero Germanicus.

Tiberius retreated to the island of Rhodes, reinstated the out-of-date charge of maiestas (treachery), and used this to sentence to death anybody he was suspicious of. Roman historians Suetonius and Tacitus describe this retreat as the result of Tiberius’ difficult relationship with his wife who was not faithful to him, but this could be speculation.

Tiberius was not a great leader himself, but rather set the tone for what was to come.

8. Nero

Nero Roman Emperor

Nero was a ruthless ruler, and he was instrumental in the demise of many men including his mentor, the writer Seneca. He had his own mother killed, and he left his wife, Octavia, for his lover Poppeaea, whom he later married. He exiled Octavia and then had her executed on a fabricated charge of unfaithfulness.

Despite being a brutal and ruthless emperor, Nero was also fond of music and poetry, often forcing people to sit through renditions of his own lengthy compositions. At one point, he insisted on being crowned the winner of the Olympic Games himself. Few sources paint Nero in a favorable light; he was generally a deeply unpopular leader.

9. Gaius (Caligula)

Gaius Caligula Roman Emperor

Gaius, otherwise known as Caligula or “little boots,” was best known for the developments he made in naval warfare. Gaius undermined the Senate, declaring that anybody could serve as a senator, even his horse (although it is believed he never went ahead with this appointment). Like Tiberius, he had a habit of getting rid of anyone who challenged him, genuine or imagined.

Despite considering himself divine and immortal, Caligula met his end when he was assassinated by Cassius Chaerea, a member of the Praetorian Guard, during the Palatine Games in 41 AD.

10. Commodus

Commodus

Commodus was the son of Marcus Aurelius and history reports that Commodus was the exact opposite of his father. Vain and self-seeking, Commodus bankrupted the Roman treasury, and in an attempt to boost funds, he killed local noblemen so that he could appropriate their property and sell it off.

Before long, people (including his own sister) were plotting against him. The plots were thwarted, and Commodus continued to execute anyone who he believed was plotting against him, or anyone he thought might do so in the future. He was eventually assassinated by a member of the Praetorian Guard who strangled him in the bath.

11. Eastern Roman Empire

Over time, the Roman Empire extended its borders to such an extent that it became loosely defined as the eastern and western regions. The two zones retained their own distinctive cultures and traditions until, in 293 AD, Emperor Diocletian formally separated east and west and appointed rulers to govern each region separately. This division resulted in the Eastern and Western Roman Empires.

Conclusion

For the first 500 years of its history, no single person held absolute power in Rome, but that all changed over the 500 years that followed. Many of the previous structures of the Roman Republic remained in place, but the Roman Empire had one overall ruler, the self-declared divine emperor.

The two halves of the Roman Empire (east and west) fell at different times. The Western Roman Empire ended in 476 AD when the last Roman emperor, Romulus Augustulus, was conquered by the German, Odoacer. The Eastern Roman Empire ended with the fall of Constantinople to the Ottoman Empire in 1453 AD.
