Commodus (Latin: Marcus Aurelius Commodus Antoninus Augustus; 31 August 161 – 31 December 192), was Roman Emperor from 180 to 192. He also ruled as co-emperor with his father Marcus Aurelius from 177 until his father's death in 180. His name changed throughout his reign; see changes of name for earlier and later forms. His accession as emperor was the first time a son had succeeded his father since Titus succeeded Vespasian in 79. Commodus was the first (and up until 337 the only) emperor "born in the purple"; i.e., born during his father's reign.
