Augustine of Hippo (354-430 AD) was a Christian theologian and philosopher from North Africa. He is best known for his influential works, including Confessions and The City of God, which explore themes of faith, grace, and the nature of God. Augustine's ideas helped shape Western Christianity and philosophy. Born in Thagaste, Augustine initially led a life of indulgence before converting to Christianity. He became the Bishop of Hippo Regius and played a crucial role in addressing theological disputes of his time, particularly concerning Original Sin and Predestination. His thoughts continue to impact Christian doctrine today.
