Caracalla’s father, Septimius Severus, died on 4 February 211 at Eboracum while on campaign in Caledonia, north of the Roman Britannia. Caracalla and his brother, Geta, jointly inherited the throne upon their father’s death. Caracalla and Geta ended the campaign in Caledonia after concluding a peace with the Caledonians that returned the border of Roman Britain to the line demarcated by Hadrian’s Wall. During the journey back to Rome with their father’s ashes, Caracalla and his brother continuously argued with one another, their relations growing increasingly hostile. Caracalla and Geta considered dividing the empire in half along the Bosphorus to make their co-rule less hostile. Caracalla was to rule in the west and Geta was to rule in the east. They were persuaded not to do this by their mother.
On 19 December 211, at a reconciliation meeting arranged by their mother, Caracalla had Geta assassinated by members of the Praetorian Guard loyal to himself, Geta dying in his mother’s arms. Caracalla then executed most of Geta’s supporters and ordered a damnatio memoriae pronounced by the Senate against his brother’s memory. Geta’s image was removed from all paintings, coins were melted down, statues were destroyed, his name was struck from papyrus records, and it became a capital offence to speak or write Geta’s name.
