Macrinus

Macrinus (c. 165–218), born at Caesarea to a Berber equestrian family, was a lawyer who became praetorian prefect under Caracalla. He had Caracalla stabbed near Carrhae on 8 April 217 and was proclaimed emperor three days later, the first ruler from outside the senatorial class; he never visited Rome.

He ruled jointly with his young son Diadumenianus and made peace with Parthia and other neighbours, but his fiscal cuts angered the army. In 218 Julia Maesa raised a revolt for her grandson Elagabalus, defeating Macrinus at Antioch on 8 June. Captured at Chalcedon and executed in Cappadocia, he suffered damnatio memoriae by the Senate.
