Historical fiction tells a story that is set in the past. That setting is usually real and drawn from history, and often contains actual historical persons, but the principal characters tend to be fictional. Writers of stories in this genre, while penning fiction, attempt to capture the manners and social conditions of the persons or time(s) presented in the story, with due attention paid to period detail and fidelity. Historical fiction is found in books, magazines, art, television programming, film, theater, and other media.
