Julia Mamaea- Daughter of Julius Avitus and Julia her Maesa. Mother of Severus Alexander. During the reign of son, she was the real power behind the throne. Rome enjoyed nine years of relative prosperity under Alexander and her. Although Mamaea was a competent civic leader, she failed as a military leader during the crisis of the Persian and German invasions. Largely as a result of her imperious manners, as well as a seeming willingness to accommodate the barbarians, she and Alexander were murdered in a mutiny by a Pannonian legion in AD 235.
