Lucius Aurelius Commodus Antoninus (31 August 161 - 31 December 192) was a Roman Emperor who ruled from 180 to 192 (also with his father, Marcus Aurelius, from 177 until 180). The name given here was his official name at his accession to sole rule; 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 emperor "born to the purple"; i.e., born during his father's reign.
