When Septimius Severus died in
Eboracum on 4 February 211, Caracalla and Geta were proclaimed joint emperors and returned to Rome. Their mother,
Julia Domna, who had served as a crucial advisor and confidante to her husband, was able to maintain her political influence over the two co-emperors. It is said that on the journey from Britain to Rome the two brothers kept away from each other, not once lodging in the same house or sharing a common meal. , 1766–1828 (
Staatsgalerie Stuttgart) Their joint rule was a failure. The Imperial Palace was divided into two separate sections, and neither allowed the servants of the other into his own. They only met in the presence of their mother, and with a strong military guard, being in constant fear of assassination. The current stability of their joint government was only through the mediation and leadership of their mother, Julia Domna, accompanied by other senior courtiers and generals in the military. The historian
Herodian asserted that the brothers decided to split the empire in two halves, but with the strong opposition of their mother, the idea was rejected, when, by the end of 211, the situation had become unbearable. Caracalla tried unsuccessfully to murder Geta during the festival of
Saturnalia (17 December). Finally, the next week, Caracalla had their mother arrange a peace meeting with his brother in her apartments, thus depriving Geta of his bodyguards, and then had him murdered in her arms by
centurions. ) Caracalla ordered the
damnatio memoriae, which was thoroughly carried out, as is clear from the archaeological record. Reportedly, Caracalla was thereafter tormented by guilt over his deed, but sought to expiate it by adding to this crime the
proscription of all his brother's former followers.
Cassius Dio stated that around 20,000 men and women were killed or proscribed on this charge during this time. ==Portrait==
