Which philosopher-emperor wrote 'Meditations'? (r. 161-180 AD)

The story behind the answer

Marcus Aurelius, the “philosopher-emperor” (r. 161–180 AD), wrote Meditations—personal Stoic reflections composed in Greek, likely during military campaigns along the Danube. Titled “To Himself” (Ta eis heauton), these notes explore self-discipline, duty, and the impermanence of life, embodying Stoic ideals while he led the empire through the Marcomannic Wars and the Antonine Plague.

To remember: M for Marcus, M for Meditations. Lucius Verus was Marcus’s co-emperor but not the author; Seneca the Younger was a Stoic philosopher and advisor to Nero, not an emperor; Cicero was a statesman and orator of the late Republic, a century earlier. Marcus Aurelius remains the closest historical example to Plato’s “philosopher-king,” uniting imperial authority with reflective, ethical thought.
