Marcus Opellius Macrinus was Roman emperor from April 217 to June 218, reigning jointly with his young son Diadumenianus. As a member of the equestrian class, he became the first emperor who did not hail from the senatorial class and also the first emperor who never visited Rome during his reign. Before becoming emperor, Macrinus served under Emperor Caracalla as a praetorian prefect and dealt with Rome's civil affairs. He later conspired against Caracalla and had him murdered in a bid to protect his own life, succeeding him as emperor.
The Severan dynasty was an Ancient Roman imperial dynasty that ruled the Roman Empire between 193 and 235, during the Roman imperial period. The dynasty was founded by the emperor Septimius Severus, who rose to power after the Year of the Five Emperors as the victor of the civil war of 193–197, and his wife, Julia Domna. After the short reigns and assassinations of their two sons, Caracalla and Geta, who succeeded their father in the government of the empire, Julia Domna's relatives themselves assumed power by raising Elagabalus and then Severus Alexander to the imperial office.
