The works of American author Edgar Allan Poe include many poems, short stories, and one novel. His fiction spans multiple genres, including horror fiction, adventure, science fiction, and detective fiction, a genre he is credited with inventing. These works are generally considered part of the Dark romanticism movement, a literary reaction to Transcendentalism. Poe's writing reflects his literary theories: he disagreed with didacticism and allegory. Poe became a household name with the publication of "The Raven" in 1845.
