Fantasy is a genre of fiction that commonly uses magic and other supernatural phenomena as a primary element of plot, theme, or setting. Many works within the genre take place in imaginary worlds where magic is common. Fantasy is generally distinguished from the genre of science fiction by the expectation that it steers clear of scientific themes, though there is a great deal of overlap between the two, both of which are subgenres of speculative fiction.
In popular culture, the genre of fantasy is dominated by its medievalist form, especially since the worldwide success of The Lord of the Rings and related books by J. R. R. Tolkien. Fantasy has also included wizards, sorcerers, witchcraft, etc., in events which avoid horror. In its broadest sense, however, fantasy comprises works by many writers, artists, filmmakers, and musicians, from ancient myths and legends to many recent works embraced by a wide audience today.
