Children's fantasy is a subgenre of fantasy literature intended for young readers. It may also refer to fantasy read by children, regardless of the intended audience.
The genre has roots in folk tales such as Aesop's Fables that were not originally intended for children: before the Victorian era, fairytales were perceived as immoral and ill-suited for children's minds. A market for children's fantasy was established in Britain in the 19th century, leading to works such as Lewis Carroll's Alice in Wonderland and Edith Nesbit's Five Children series; the genre also developed in America, exemplified by L. Frank Baum's The Wonderful Wizard of Oz. Of the authors of this period, Nesbit is commonly cited as the creator of modern children's fantasy.
