Commodus

Commodus (; 31 August 161 – 31 December 192) was a Roman emperor who ruled from 177 to 192. He served jointly with his father Marcus Aurelius from 177 until the latter's death in 180, and thereafter he reigned alone until his assassination by Narcissus. His reign is commonly thought to mark the end of a golden age of peace and prosperity in the history of the Roman Empire (the Pax Romana).
Commodus accompanied his father during the Marcomannic Wars in 172 and on a tour of the Eastern provinces in 176. The following year, he became the youngest emperor and consul up to that point, at the age of 16. His solo reign saw less military conflict than that of Marcus Aurelius, but internal intrigues and conspiracies abounded, goading Commodus to an increasingly dictatorial style of leadership. This culminated in his creating a deific personality cult, including his performances as a gladiator in the Colosseum. Throughout his reign, Commodus entrusted the management of affairs to his palace chamberlain and praetorian prefects, namely Saoterus, Perennis and Cleander.
Commodus' assassination in 192, by a wrestler in the bath who held him underwater, marked the end of the Nerva–Antonine dynasty. He was succeeded by Pertinax, the first claimant in the tumultuous Year of the Five Emperors.
