Pertinax died

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.
