Answer
Elagabalus was assassinated in 222 AD. The Praetorian Guard, led by Macrinus, killed him and his mother Julia Soaemias. Elagabalus was a young boy when he became emperor, and he was not popular with the people or the army. He was known for his eccentric behavior and his lavish spending. Macrinus, who was a more experienced and capable ruler, was able to seize power and have Elagabalus killed.
