Marcus Aurelius Antoninus, better known by his posthumous nicknames Elagabalus and Heliogabalus, was Roman emperor from 218 to 222, while he was still a teenager. His short reign was notorious for religious controversy and alleged sexual debauchery. A close relative to the Severan dynasty, he came from a prominent Syrian Arab family in Emesa (Homs), Syria, where he served as the head priest of the sun god Elagabal from a young age. After the death of his cousin, the emperor Caracalla, Elagabalus was raised to the principate at 14 years of age in an army revolt instigated by his grandmother Julia Maesa against Caracalla's short-lived successor, Macrinus. He only posthumously became known by the Latinised name of his god.
Julia Soaemias Bassiana was a Syrian noblewoman and the mother of Roman emperor Elagabalus, who ruled over the Roman Empire from 218 to 222. She was one of his chief advisors, initially with the support and accompaniment of her mother Julia Maesa. She and her mother guided the young emperor until growing unrest and a family division led to her son's replacement by her nephew Severus Alexander. Julia Soaemias was killed along with her son by the Praetorian Guard.
Marcus Aurelius Severus Alexander, also known as Alexander Severus, was Roman emperor from 222 until 235. He was the last emperor from the Severan dynasty.
