On 28 March 193, Pertinax was at his palace when a contingent of some three hundred soldiers of the Praetorian Guard rushed the gates (two hundred according to Cassius Dio). Sources suggest that they had received only half their promised pay. Neither the guards on duty nor the palace officials chose to resist them. Pertinax sent Laetus to meet them, but he chose to side with the insurgents instead and deserted the emperor.
Because Julianus bought his position rather than acquiring it conventionally through succession or conquest, he was a deeply unpopular emperor. When Julianus appeared in public, he frequently was greeted with groans and shouts of "robber and parricide." Once, a mob even obstructed his progress to the Capitol by pelting him with large stones.
