ペスケンニウス・ニゲル
Didius Julianus gained power as proconsul of Africa, succeeding Pertinax in that position. Julianus was not just given the position of emperor after Pertinax's death. He had competition in Pertinax's father-in-law, Sulpicianus. The only way that Julianus gained the throne was by outbidding Sulpicianus for the amount he would pay the troops, thus gaining the favour of the Praetorian Guard. Julianus was originally accused of being Pertinax's murderer. Two public figures used the public's fear to take advantage of this crisis: Pescennius Niger, the governor of Syria, and Septimius Severus. Twelve days after Pertinax's murder, Severus declared himself emperor in place of Julianus. The mobs, who regarded Julianus unfavorably, called on Pescennius Niger for assistance. However, Severus, in Pannonia, was closest to Rome, and reached the capital first with his troops. Julianus was executed on June 1 on the orders of Severus, just two months after Pertinax was killed.
