Fantasy is a genre that uses magic and other supernatural phenomena as a primary element of plot, theme, and/or setting. Many works within the genre take place in fictional worlds where magic is common. Fantasy is generally distinguished from science fiction in that it does not provide a logical (or pseudo logical) explanation for the scientifically impossible events that occur, though there is a great deal of overlap between the two (both 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 books by J. R. R. Tolkien. 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.
Fantasy is a vibrant area of academic study in a number of disciplines (English, cultural studies, comparative literature, history, 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
