Pertinax (Latin: Publius Helvius Pertinax Augustus; 1 August 126 – 28 March 193) was Roman Emperor for three months in 193. He is known as the first emperor of the tumultuous Year of the Five Emperors. A high-ranking military and Senatorial figure, he tried to restore discipline in thePraetorian Guards, whereupon they rebelled and killed him. Upon his death he was succeeded by Didius Julianus, whose reign was similarly short. His career before becoming emperor is documented in the Historia Augusta and confirmed in many places by existing inscriptions. Born in Alba Pompeia in Italy, the son of freedmanHelvius Successus, originally Pertinax made his way as a grammaticus (teacher of grammar), but he eventually decided to find a more rewarding line of work and through the help of patronage he was commissioned an officer in a cohort.
- In the Parthian war that followed, he was able to distinguish himself, which resulted in a string of promotions, and after postings in Britain (as military tribune of the Legio VI Victrix) and along the Danube, he served as a procurator in Dacia. He suffered a setback as a victim of court intrigues during the reign of Marcus Aurelius, but shortly afterwards he was recalled to assist Claudius Pompeianus in the Marcomannic Wars. In 175 he received the honor of a suffect consulship and until 185, Pertinax was governor of the provinces of Upper and Lower Moesia, Dacia, Syria and finally governor of Britain.

In the decade of the 180s, Pertinax took a pivotal role in the Roman Senate until the praetorian prefect Sextus Tigidius Perennis forced him out of public life.He was recalled after three years to Britain, where the Roman army was in a state of mutiny. He tried to quell the unruly soldiers there but one legion mutinied and attacked his bodyguard, leaving Pertinax for dead. When he recovered, he punished the mutineers severely, which led to his growing reputation as a disciplinarian. When he was forced to resign in 187, the reason given was that the legions had grown hostile to him because of his harsh rule.
He served as proconsul of Africa during the years 188–189, and followed this term of service with the urban prefecture of Rome, and a second consulship as ordinarius with the emperor as his colleague.
Emperor
When Commodus' behaviour became increasingly erratic throughout the early 190s, Pertinax is thought to have been implicated in the conspiracy that led to his assassination on 31 December 192. The plot was carried out by the Praetorian prefect Quintus Aemilius Laetus, Commodus' mistress Marcia, and his chamberlain Eclectus. After the murder had been carried out, Pertinax, who was serving as urban prefect at this time, was hurried to the Praetorian Campand proclaimed emperor the following morning. His short reign (86 days) was an uneasy one. He attempted to emulate the restrained practices of Marcus Aurelius, and made an effort to reform the alimenta but he faced antagonism from many quarters.
