Marcus Aurelius and Lucius Verus Become Co‑Emperors of Rome
On March 7, 161, the Roman emperor Antoninus Pius died, and the Senate recognized Marcus Aurelius and Lucius Verus as joint emperors. This unusual power‑sharing arrangement paired the philosophical Marcus with the more militarily inclined Verus. Their reign saw major wars on the empire’s eastern frontier, especially against the Parthians. The co‑rule experiment did not last long in Roman history, but it set the stage for Marcus Aurelius’s later solo reign, remembered for both conflict and his Stoic writings.
