Augustine was born in Thagaste, in present-day Algeria, and had a turbulent youth before converting to Christianity. He became bishop of Hippo and wrote decisive works such as the Confessions and The City of God. By joining Christian faith to Platonic philosophy, he became the most influential thinker of the early Middle Ages.
