The Call of the Wild is a novel by Jack London published in 1903. The story is set in the Yukon during the 1890s Klondike Gold Rush—a period in which strong sled dogs were in high demand. The novel's central character is a dog named Buck, a domesticated dog living at a ranch in the Santa Clara Valley of California as the story opens. Stolen from his home and sold into service as sled dog in Alaska, he reverts to a wild state. Buck is forced to fight in order to dominate other dogs in a harsh climate. Eventually he sheds the veneer of civilization, relying on primordial instincts and learned experience to emerge as a leader in the wild. London lived for most of a year in the Yukon collecting material for the book. The story was serialized in the Saturday Evening Post in the summer of 1903; a month later it was released in book form. The novel’s great popularity and success made a reputation for London. Much of its appeal derives from the simplicity of this tale of survival. As early as 1908 the story was adapted to film and it has since seen several more cinematic adaptations.
