Didius Julianus (/ˈdɪdiəs/; Latin: Marcus Didius Severus Julianus Augustus; (30 January 133 or 2 February 137 – 1 June 193) was Roman emperor for nine weeks from March to June 193, during the Year of the Five Emperors.
He ascended the throne after buying it from the Praetorian Guard, who had assassinated his predecessor Pertinax. A civil war ensued in which three rival generals laid claim to the imperial throne. Septimius Severus, commander of the legions in Pannonia and the nearest of the generals to Rome, marched on the capital, gathering support along the way and easily defeating those sent to impede his progress.
Abandoned by the Senate and the Praetorian Guard, Julianus was killed by a soldier in the palace and succeeded by Severus.
