Marcus Didius Julianus (193 AD)

After hearing news that of Julianus had purchased the principate, two legates Severus and Niger immediately revolted. Plubius Septimius Severus being the closest to Rome, marched to the capital with the support of a large army. At first, Julianius tried to put up resistance; then he attempted negotiations with Severus. When all else failed, the Praetorian Guard abandoned him and after 30 days of reign; Julianus was assassinated on June 1. Shortly after, Severus entered the city.
