Marcus Aurelius (121 – 180) Latin: Marcus Aurelius Antoninus Augustus; was Roman emperor from 161 to 180 and a Stoic philosopher. He was the last of the rulers traditionally known as the Five Good Emperors, and the last emperor of the Pax Romana, an age of relative peace and stability for the Roman Empire. He served as Roman consul in 140, 145, and 161.
The son of the praetor Marcus Annius Verus (III) and the wealthy heiress Domitia Lucilla, Marcus was raised by his grandfather, Marcus Annius Verus (II), after his father died. His uncle, Antoninus Pius, adopted him shortly before becoming emperor in 138. Now the heir to the throne, Marcus studied Greek and Latin under tutors such as Herodes Atticus and Marcus Cornelius Fronto. He kept in close correspondence with Fronto for many years afterward. Marcus married Antoninus’ daughter Faustina in 145. Antoninus died following an illness in 161.
