Marcus Aurelius, future Roman emperor and Stoic philosopher, is born in Rome.
Marcus Aurelius is considered the last of the "Five Good Emperors," Roman emperors who achieved their station through adoption rather than blood relations and who, while being absolute rulers, nevertheless display more virtue and good judgment than is otherwise observed in the history of the Roman Empire.
Even during his lifetime, Marcus Aurelius will often be described as a "philosopher king" and the appellation continues long after his death. His book Meditations will be written while on military campaigns and it will become a landmark work in Stoic philosophy. Written in educated Greek, it will be intended for his own edification and self-improvement.
