Life
Marcus Aurelius (121–180), last of the "Five Good Emperors," ruled Rome through wars on the Danube and Parthian frontiers and a devastating plague, striving to govern with duty and reason. Amid campaigns he kept a private journal of Stoic reflection — the Meditations — never meant for publication, which became a timeless guide to self-discipline, acceptance, and virtue. Praised as the philosopher on the throne, he is also weighed by historians for the persecution of Christians in his reign and for leaving the empire to his flawed son Commodus. His figure here complements the philosophers' entry devoted to him.
