Fantasy is a genre of fiction that uses magic or other supernatural elements as a main plot element, theme, or setting. Many works within the genre take place in imaginary worlds where magic and magical creatures are common. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction.In popular culture, the fantasy genre is predominantly of the medievalist form. In its broadest sense, however, fantasy comprises works by many writers, artists, filmmakers, and musicians, from ancient myths and legends to many recent and popular works.Fantasy is studied in a number of disciplines including English and other language studies, cultural studies, comparative literature, history, and medieval studies. Work in this area ranges widely, from the structuralist theory of Tzvetan Todorov, which emphasizes the fantastic as a liminal space, to work on the connections (political, historical, literary) between medievalism and popular culture.
