Roman Emperors from the Severan Dynasty and their reigns

The Severan Dynasty (193-235 AD) was a crucial period in Roman history, established by Septimius Severus after his triumph in the Year of the Five Emperors. Hailing from Leptis Magna in modern-day Libya, the dynasty blended North African influences with Roman governance.

Their more than four-decade rule saw major cultural and political shifts, and confronted challenges like internal strife and military threats. Caracalla, a prominent figure, granted Roman citizenship to all free men, while emperors like Elagabalus and Alexander Severus are remembered for their controversial reigns. Preceding the Crisis of the Third Century, the Severans’ era encapsulates both the peak of Roman imperial might and the early signs of its decline.

Lucius Septimius Severus was the Roman emperor from 193 to 211. Born in Leptis Magna, present-day Libya, he rose through ranks under Marcus Aurelius and Commodus.

In 193, following Emperor Pertinax’s death, Severus grabbed power, defeating Didius Julianus, and later vanquished rivals Pescennius Niger and Clodius Albinus in separate battles.

Septimius annexed the Kingdom of Osroene, expanded the empire’s eastern boundary to the Tigris, defeated the Parthian Empire, and enhanced the Limes Arabicus.

He also campaigned in Africa, extending the Limes Tripolitanus. His sons, Caracalla and Geta, were named co-emperors, and with his second wife Julia Domna, they established the Severan dynasty.

In 208, he bolstered defenses in Britain, and launched a massive invasion of Caledonia in 209. However, an illness struck him in 210, leading to his death in Eboracum (now York, England) in 211. His dynasty preceded the Crisis of the Third Century.

Caracalla, born as Lucius Septimius Bassianus in 188 AD, was a Roman emperor from 198 to 217 AD and part of the Severan dynasty. He was the elder son of Emperor Septimius Severus and Empress Julia Domna.

The Roman Empire during the reign of Caracalla

After his father’s death in 211, he ruled jointly with his brother Geta, whom he had murdered later that year, making him the sole ruler. While he was disinterested in administrative duties, relying heavily on his mother for governance, Caracalla was known for the Antonine Constitution, which granted Roman citizenship to all free men in the empire.

Other notable aspects of his reign include constructing the Baths of Caracalla, introducing the antoninianus currency, and initiating various massacres. Although he started a campaign against the Parthian Empire, he was assassinated in 217 before its conclusion. Historical accounts, both ancient and modern, often depict Caracalla as a tyrannical and cruel leader.

Geta (reigned: 209–211 AD)

Co-emperor with Caracalla, his reign was brief, and he was assassinated by his brother’s agents.

Publius Septimius Geta was a Roman emperor who co-ruled with his father, Septimius Severus, and his older brother, Caracalla. He was granted the title of Augustus in 209, a title his brother Caracalla had already held from 198.

After their father’s death in 211, the plan was for the brothers to jointly rule the empire. However, their relationship was contentious, and they were unable to cooperate effectively. This deep-seated animosity between the brothers reached its tragic climax when Geta was murdered in December 211, just months after their father’s death, leaving Caracalla as the sole emperor.

Macrinus (reigned: 217–218 AD)

Born into an Equestrian class (i.e. the second of the property-holding classes of Rome), Macrinus served under Emperor Caracalla as a praetorian prefect. He handled the civil affairs of the empire. Macrinus became emperor in April 217 after he and his Praetorian Guard murdered Caracalla. Image: Bust of Roman Emperor Macrinus, Capitoline Museums

Marcus Opellius Macrinus, reigning from April 217 to June 218 alongside his son Diadumenianus, was unique as he was the first Roman emperor from the equestrian class, and never visited Rome during his rule.

Originally serving under Emperor Caracalla as a praetorian prefect, he conspired to assassinate Caracalla, subsequently becoming emperor. Although Macrinus initiated diplomatic reforms to restore Rome’s economy and stabilize relations with neighboring kingdoms, his increased military expenses and fiscal changes caused unrest among the Roman military. Caracalla’s aunt, Julia Maesa, exploited this discontent, leading a rebellion that elevated her grandson, Elagabalus, as emperor.

Macrinus was defeated at the Battle of Antioch in June 218, attempted to flee, but was captured and executed. His son, Diadumenian, shared a similar fate. Following their deaths, the Senate erased all records of them, a practice known as “damnatio memoriae.”

Elagabalus (reigned: 218–222 AD)

Elagabalus (Marcus Aurelius Antoninus Augustus) was a Roman emperor who ruled from 218 to 222 CE. He was born in Syria in 203 CE and was the cousin of the previous emperor, Caracalla. Elagabalus became emperor at the age of 14, after the assassination of Caracalla.

Elagabalus, born as Sextus Varius Avitus Bassianus around 204, became the Roman emperor from 218 to 222 as a teenager. Hailing from a distinguished Arab family in Emesa (Homs), Syria, he was deeply involved in the worship of the sun god Elagabal.

His ascent to power at age 14 was facilitated by his grandmother, Julia Maesa, who led a revolt against Macrinus, Caracalla’s successor. His reign was marked by religious upheavals, as he promoted the deity Elagabal over Jupiter and insisted that Roman leaders participate in these new rites.

A member of the Severan family, Emperor Elagabalus reign was marked by religious controversies and is considered one of the most eccentric reigns in Roman history.

Furthermore, Elagabalus’s personal life was filled with scandals, involving multiple marriages, alleged relationships with male courtiers, and reports of prostitution.

His controversial actions alienated many, leading to his assassination at age 18, orchestrated by Julia Maesa and discontented Praetorian Guard members. Historically, Elagabalus has been heavily criticized for his eccentricity and perceived decadence, but some modern scholars view him as a misunderstood figure with genuine religious convictions.

Alexander Severus (reigned: 222–235 AD)

The last emperor of the Severan dynasty, Alexander Severus (reigned: 13 March 222 – 22 March 235) tried to rule judiciously but was faced with external pressures, eventually being assassinated by his troops.

Alexander Severus, born Marcus Aurelius Severus Alexander (208-235), was a Roman emperor who ruled from 222 to 235 and was the final emperor of the Severan dynasty.

He became emperor following the assassination of his cousin, Elagabalus. Both were grandsons of Julia Maesa, who played a significant role in elevating Elagabalus to the throne. Alexander’s reign, lasting 13 years, was marked by prosperity and was the longest sole emperorship since Antoninus Pius.

Julia Maesa (7 May before 160 AD – c. 224 AD) was a pivotal figure in the Severan dynasty of the Roman Empire. She was the elder sister of empress Julia Domna and mother to Julia Soaemias and Julia Mamaea. Significantly, she was the grandmother of emperors Elagabalus and Severus Alexander, positioning her at the heart of the dynasty’s power dynamics.

Notably young when he assumed power, he was only surpassed in age by Gordian III. While he successfully countered threats from the Sassanid Empire, his diplomatic and appeasement tactics against Germanic tribes were unpopular with the Roman army. This discontent led to a conspiracy, culminating in the assassination of Alexander, his mother, and close advisors.

His death ushered in the Crisis of the Third Century, characterized by widespread turmoil and instability in the Roman Empire.

The Baths of Caracalla, known in Latin as “Thermae Antoninianae,” were one of the largest and most extravagant public bathhouses in ancient Rome. Constructed between 212 and 216 AD during the reign of Emperor Caracalla (Marcus Aurelius Antoninus), these baths were a testament to the grandeur of Roman architecture and the significance of public bathing in Roman culture.
