Severan dynasty

The Severan dynasty of Roman emperors spanned the reigns of Septimius Severus (A.D. 193–211), Caracalla (211–217), Macrinus (217–218), Heliogabalus (218–222), and Alexander Severus (222–235).

The women of the Severan dynasty, beginning with Septimius Severus's wife Julia Domna, were notably active in advancing the careers of their male relatives.
