Marcus Aurelius Antoninus Augustus was Roman Emperor from 161 to his death in 180. He was the last of the "Five Good Emperors", and is also considered one of the most important Stoic philosophers.
His tenure was marked by wars in Asia against a revitalized Parthian Empire, and with Germanic tribes along the Limes Germanicus into Gaul and across the Danube. A revolt in the East, led by Avidius Cassius, failed.
