Marcus Aurelius was Emperor of the Roman Empire from 161 to 180 CE. Considered the last of the Five Good Emperors, he oversaw his empire with stoicism and equality. In his Meditations, written while on a military campaign in the last decade of his life, he sets forth a series of aphorisms, letters, and principles that he tried to live by. As a stoic, he thought that powerful emotions were the cause of errors in life and so sought to live a life of a more moral and intellectual manner.
