Marcus Aurelius, Emperor of Rome, 121-180.
Roman emperor from 161 to his death in 180. He ruled with Lucius Verus as co-emperor from 161 until Lucius' death in 169. 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.
Marcus Aurelius' work Meditations, written in Greek while on campaign between 170 and 180, is still revered as a literary monument to a government of service and duty.
