Julia Avita Mamaea was the younger daughter of Julia Maesa. After the murder of Elagabalus, Julia Mamaea received the title of Augusta, when her young son, Severus Alexander, became emperor in AD 222. Julia Maesa died in AD 226, and Julia Mamaea took control of Severan family matters. Together with Alexander she participated and directed matters of state. Her popularity waned during the later phase of Alexander's reign. During a coup of the Praetorian Guard in AD 235 both were murdered.
