Severan Dynasty: How Soldier Emperors Transformed Rome from AD 193 to 235

The Severan Dynasty governed the Roman Empire from AD 193 until 235, a time when emperors increasingly relied on military support. In February AD 211, Septimius Severus passed away in Eboracum (York), urging his sons to prioritize soldiers over others. This dynasty emerged after Commodus was assassinated on New Year's Eve in AD 192, leading to the chaotic Year of the Five Emperors. Pertinax, who attempted budget reforms and refused to bribe the Praetorian Guard, was killed in under three months. The Praetorians then sold the throne to Didius Julianus. Severus, from Lepcis Magna in North Africa, was named imperator by his legions and marched to defeat Pescennius Niger in AD 194 and Clodius Albinus in February AD 197. He raised military pay, altered coinage, and erected the Arch of Septimius Severus. His son Caracalla killed his brother Geta, embraced the soldier-emperor persona, and enacted the Constitutio Antoniniana in AD 212. Caracalla was assassinated in AD 217 by Julius Martialis, leading to Macrinus’s short reign as the first equestrian emperor. Elagabalus, a young priest from Syria, ruled from AD 218 to 222 before being murdered by the Praetorians. The last Severan, Severus Alexander, was killed by his troops at Moguntiacum in March 235, paving the way for Maximinus Thrax and the onset of the Crisis of the Third Century.
