Historical fantasy is a category of fantasy and genre of historical fiction that incorporates fantastic elements into a more "realistic" narrative. There is much crossover with other subgenres of fantasy; those classed as Arthurian, Celtic, or Dark Ages could just as easily be placed in historical fantasy. Stories fitting this classification generally take place prior to the 20th century.

Fantasy is a genre of speculative fiction involving magical elements, typically set in a fantasy world and usually inspired by mythology or folklore. The term "fantasy" can also be used to describe a "work of this genre", usually literary.
