In 211 after the death of Lucius Septimius Severus, his sons Caracalla and Publius Septimius Geta succeeded their father on the Roman throne. Caracalla recalled Marcellus from Roman Britain to Rome and briefly placed him in the roles of Praefectus urbi and Praetorian prefect. He was later admitted into the Senate and, soon after, became praefectus of the military treasury. He later became governor of Numidia and held this post until his death.
