Marcus Aurelius Antoninus was a Stoic philosopher and Roman emperor born in 121 CE. He was adopted by, and eventually succeeded, the emperor Antoninus Pius. The last emperor in what is known as the Pax Romana, a period of relative stability and peace, he has since become known for his Meditations, reflections on his later years that were never meant for formal publication. He died in 180.
