Robinson Crusoe is a novel by Daniel Defoe, first published on 25 April 1719. The first edition credited the work's protagonist Robinson Crusoe as its author, leading many readers to believe he was a real person and the book a travelogue of true incidents.
Epistolary, confessional, and didactic in form, the book is presented as an autobiography of the title character (whose birth name is Robinson Kreutznaer)a castaway who spends thirty years on a remote tropical island near Trinidad, encountering cannibals, captives, and mutineers before being rescued.
Taken as non-fiction, the details of Robinson Crusoe are given at the start of the novel. The story has since been perceived to be based on the life of Alexander Selkirk, a Scottish castaway who lived for four years on the Pacific island of Chile.
