The Call of the Wild is a novella by American author Jack London published in 1903.
The story takes place in the extreme conditions of the Yukon during the 19th-century Klondike Gold Rush, where strong sled dogs were in high demand. After Buck, a domesticated dog, is snatched from a pastoral ranch in California, he is sold into a brutal life as a sled dog.
The novella details Buck's struggle to adjust and survive the cruel treatment he receives from humans, other dogs, and nature. He eventually sheds the veneer of civilization altogether and instead relies on primordial instincts and the lessons he has learned to become a respected and feared leader in the wild.
London lived for most of a year in the Yukon and gained from that experience material for the book. The story was serialized in the Saturday Evening Post in the summer of 1903 and released a month later in book form. The great popularity and success of the story made a reputation for London, with much of the story's appeal based on the simplicity with which he presented the themes in an almost mythical manner. As early as 1908 the story was adapted to film and has seen several more cinematic adaptations since that time.
