Robinson Crusoe runs away to sea, is wrecked, and leads a solitary existence on an uninhabited island near the Orinoco river for twenty-four years. He finds consolation in the Bible and after a while meets another human, a young native whom he saves from death and calls Man Friday, because he met him on a Friday.

Defoe based his story on the adventures of Scottish castaway Alexander Selkirk. Published in 1719, Robinson Crusoe is one of the first novels in the English language and is often credited as marking the beginning of realistic fiction as a literary genre. It is one of the most widely read books in history, spawning numerous sequels and adaptations for stage, film, and television.
