Oliver Twist; or, The Parish Boy's Progress, is the second novel by English author Charles Dickens. It was originally published as a serial from 1837 to 1839, and as a three-volume book in 1838. The story follows the titular orphan, who, after being raised in a workhouse, escapes to London, where he meets a gang of juvenile pickpockets led by the elderly criminal Fagin, discovers the secrets of his parentage, and reconnects with his remaining family. Oliver Twist unromantically portrays the sordid lives of criminals, and exposes the cruel treatment of the many orphans in London in the mid-19th century. The alternative title, The Parish Boy's Progress, alludes to Bunyan's The Pilgrim's Progress, as well as the 18th-century caricature series by painter William Hogarth, A Rake's Progress and A Harlot's Progress. In an early example of the social novel, Dickens satirises child labour, domestic violence, the recruitment of children as criminals, and the presence of street children. The novel may have been inspired by the story of Robert Blincoe, an orphan whose account of working as a child labourer in a cotton mill was widely read in the 1830s. It is likely that Dickens's own experiences as a youth contributed as well, considering he spent two years of his life in the workhouse at the age of 12 and subsequently, missed out on some of his education. Oliver Twist has been the subject of numerous adaptations, including a 1948 film of the same title, starring Alec Guinness as Fagin; a highly successful musical, Oliver! (itself adapted into a multiple Academy Award-winning 1968 motion picture), and Disney's animated film Oliver & Company in 1988.
