Roman Emperor For A Short Time Under The Name Of Marcus Didius Commodus Severus Julianus Marcus Didius Salvius Julianus, born about A. D. 133, killed June 1, 193. Having filled successively the offices of quaestor, aedile, and praetor, he was appointed to the command of a legion in Germany, and afterward to the government of Belgic Gaul. Here he showed much energy in repressing an insurrection of the Chauci, and for this service he was made consul. He also distinguished himself against the Catti, was governor of Dalmatia and afterward of Lower Germany, and then took charge of the commissariat in Italy. After this he was governor of Bithynia in Asia Minor, was again consul in 179, and having filled the office of proconsul of Africa, returned to Rome, where he was made commander of the city guards. After the assassination of Pertinax, the praetorian guards offered the imperial throne to him who would pay the highest price; and after a brisk bidding against Sulpicianus, prefect of the city, Didius obtained it. The senate was obedient to the will of the unruly soldiery, and Didius was acknowledged emperor.

But whenever he appeared in public he was received with cries of "Robber and parricide." Moreover, he was not recognized as emperor by Septimius Severus, who held command of three legions in Illyria, by Clodius Albums, nor by Pescennius Niger, who held like commands in Britain and Syria respectively. Severus, having been proclaimed emperor by his troops, marched upon Rome, and was recognized by the senate. Deserted by his adherents, Didius was murdered in his palace by a common soldier, having reigned a little more than two months,' and Septimius Severus established himself in his place.
