The Severan dynasty was a Roman imperial dynasty, which ruled the Roman Empire between 193 and 235. The dynasty was founded by the Roman general Septimius Severus, who rose to power as the victor of the 193-197 civil war. Although Septimius Severus successfully restored peace following the upheaval of the late 2nd century, the dynasty was disturbed by highly unstable family relationships, and constant political turmoil, foreshadowing the imminent Crisis of the Third Century. It was the last lineage of the Principate founded by Augustus.
