Answer
Elagabalus was raised to the principate when he was 14 years old. This was an unusual age for someone to be made emperor, as most emperors were much older. However, Elagabalus' father, the previous emperor, had been assassinated, and the Praetorian Guard decided that Elagabalus was the best candidate to succeed him. Elagabalus was a controversial figure, and he was eventually assassinated by the Praetorian Guard as well.
