The works of American author Edgar Allan Poe (January 19, 1809 – October 7, 1849) 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.
