Aulus Ceionius Commodus was a Roman politician and member of the Senate during the early 2nd century AD. He is best known for being the adopted son of the Emperor Marcus Aurelius, which positioned him as a potential heir to the throne. Commodus was part of a prominent family, and his lineage connected him to influential figures in Roman history. Despite his noble background, Commodus's life was marked by political intrigue and challenges. He served as a consul and was involved in various administrative roles, but he did not ascend to the imperial throne. His legacy remains largely overshadowed by the more famous reign of his adoptive father, Marcus Aurelius.
