The English novel has a long and complex development. It began in the 17th century with works like 'The Canterbury Tales' which had elements of a novel in its collection of stories. Then in the 18th century, the novel really started to take shape with the works of Daniel Defoe, such as 'Robinson Crusoe'. In the 19th century, the English novel reached new heights with the works of Jane Austen, Charles Dickens, and the Brontë sisters. Austen's novels focused on the social life of the gentry, while Dickens explored the social problems of the working class. The Brontë sisters brought a new level of passion and emotion to the novel. In the 20th century, modernist and post - modernist novels emerged, changing the form and style of the novel even further.
