Commodus

Commodus (; 31 August 161 – 31 December 192) was a Roman emperor serving jointly with his father Marcus Aurelius from 176 until his father’s death in 180, and solely until 192. His reign is commonly thought of as marking the end of a golden period of peace in the history of the Roman Empire, known as the Pax Romana.
Commodus accompanied his father during the Marcomannic Wars in 172, and on a tour of the Eastern provinces in 176. He was made the youngest consul in Roman history in 177 and had been elevated to co-augustus with his father; he was further given the title imperator in 176. During his solo reign, the Roman Empire enjoyed reduced military conflict compared with the reign of Marcus Aurelius. Intrigues and conspiracies abounded, leading Commodus to revert to an increasingly dictatorial style of leadership, culminating in his creating a deific personality cult, with his performing as a gladiator in the Colosseum. Throughout his reign, Commodus entrusted the management of affairs to his palace chamberlain and Praetorian prefects, named Saoterus, Perennis and Cleander.
Commodus’s assassination in 192, by a wrestler in the bath, marked the end of the Nerva–Antonine dynasty. He was succeeded by Pertinax, the first emperor in the tumultuous Year of the Five Emperors.
