Elagabalus was Emperor of Rome from A.D. 218 - 222 succeeding Macrinus who had been assassinated when he became unpopular with the military after he tried to cut the pay of the troops. Elagabalus was chosen because of his bloodline to Severus. He took the name Elagabalus in reverence for the Syrian sun god.
Only about 13 years of age at the time of his ascension to the throne, the empire was really ruled by his forceful mother, Julia Soaemias . He adopted his cousin Alexander Severus as his successor. The Praetorian guard murdered Elagabalus in 222, paving the way for his cousin to rule.
