Marcus Aurelius Sabinus Julianus,[1] known in English as Julian of Pannonia (died 285–286) was a Roman usurper (283–285 or 286) against Emperor Carinus or Maximian.

[3] Soon after the news of the death of Emperor Carus[2] (in 283) or Numerian[3] (in November 284) arrived in the western provinces, Julian revolted in Pannonia.

Emperor Carinus, brother of Numerian, who had marched from Roman Britain to deal with the usurpation, met, defeated, and killed Julian early in 285, in Italy[4] (possibly in Verona),[5] or in Illyricum.

[6] Another usurper, simply named Julian, raised some turmoil in Africa Province, against Carinus, with the support of the Quinquegentani tribe.

The revolt of this Julianus took place in Italy, but ended when, during a siege, a breach was opened in the walls of his city, and he threw himself in the fire.
