Final answer:
St. Augustine of Hippo was born in 354 AD and died in 430 AD. He was a paramount figure in Christian theology with significant intellectual contributions, notably 'The City of God,' and he served as the bishop of Hippo until his death.
Step-by-step explanation:
The life of St. Augustine of Hippo, an influential Christian philosopher and theologian, spanned across the late fourth and early fifth centuries. He was born in 354 AD in Tagaste, Roman Numidia (now present-day Souk Ahras, Algeria) to a Roman colonist father and indigenous African mother. Augustine's eventful life included studies in Carthage, teaching in Milan, a profound conversion to Christianity, and significant intellectual contributions to Christian doctrine, such as his seminal work, 'The City of God.' His life was marked by efforts to resolve religious disputes, like the Donatist controversy, and responding to pressing questions of the times concerning the fall of the Roman Empire and the role of Christian faith. Augustine's tenure as the bishop of Hippo, from 395 AD until his death in 430 AD, was also notable, and he passed away as his own city faced a siege by Germanic Vandals.
