Commodus

Commodus (31 August 161 to 31 December 192) was Roman emperor from 177 to 192, first as nominal co-emperor beside his father Marcus Aurelius and from 180 as sole ruler. He went with his father on the Marcomannic Wars in 172 and on a tour of the eastern provinces in 176, and in 177 became the youngest emperor and consul to that date, at sixteen. His sole reign saw less warfare than his father's, but court intrigue and conspiracy pushed him toward increasingly autocratic rule, which culminated in a cult of his own divinity and appearances as a gladiator in the Colosseum. He left much of the running of affairs to his palace chamberlain and praetorian prefects, among them Saoterus, Perennis and Cleander. His reign is commonly taken to mark the end of the Pax Romana. He was assassinated in 192 by the wrestler Narcissus, which ended the Nerva-Antonine dynasty and opened the way for Pertinax and the Year of the Five Emperors.
