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. It was published under the full title The Life and Strange Surprizing Adventures of Robinson Crusoe, Of York, Mariner: Who lived Eight and Twenty Years, all alone in an un-inhabited Island on the Coast of America, near the Mouth of the Great River of Oroonoque; Having been cast on Shore by Shipwreck, wherein all the Men perished but himself. With An Account how he was at last as strangely deliver'd by Pyrates. 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 ultimately being rescued. The story has since been perceived to be based on the life of Alexander Selkirk, a Scottish castaway who lived for four years on a Pacific island called "Más a Tierra", now part of Chile, which was renamed Robinson Crusoe Island in 1966, but various literary sources have also been suggested.
