Roman Emperor Caracalla Was Assassinated
On this day · 8 April 217
On a roadside in Mesopotamia, a single soldier's blade ended the reign of one of Rome's most feared emperors.
On 8 April 217, the Roman emperor Caracalla was killed while travelling near Carrhae in Mesopotamia, four days after his twenty-ninth birthday. According to the surviving account, the emperor was ambushed during a roadside stop and stabbed by a soldier from his own guard named Martialis, who was promptly cut down by fellow guardsmen.
Few believed the story was so simple. Suspicion fell on the praetorian prefect Macrinus, who had reason to fear the unpredictable emperor and who took the throne within days. The killing ended the Severan dynasty’s direct male line and plunged the empire toward decades of instability.
Suspicion was strong that Macrinus arranged the entire affair.
Despite his brutal reputation, Caracalla left a lasting mark. His Constitutio Antoniniana of 212 granted Roman citizenship to nearly all free residents of the empire, and his vast public baths in Rome remained among the city’s grandest structures for centuries.
