He was educated at Eton College and King's College, Cambridge.
His 1764 novel, The Castle of Otranto, is considered the first Gothic novel. It started a literary genre that would become increasingly popular in the late Eighteenth and early Nineteenth centuries.

He was friends with Horace Mann, whom he met in Italy.
