Children's literature R. M. Ballantyne and G. A. Henty specializing in the production of adventure fiction for boys. This inspired writers who normally catered to adult audiences to write for children, and an example is Robert Louis Stevenson's (1850–94) classic pirate story "Treasure Island" (1883). In the years after the First World War, writers such as Arthur Ransome (1884–1967) developed the adventure genre by setting the adventure in Britain rather than distant countries. Ransome began publishing in 1930 his Swallows and Amazons series of children's books about the school-holiday adventures of children, mostly in the English Lake District and the Norfolk Broads.
