Proletarian literature refers here to the literature created by left-wing writers mainly for the class-conscious proletariat. Though the Encyclopædia Britannica states that because it "is essentially an intended device of revolution", it is therefore often published by the Communist Party or left wing sympathizers, the proletarian novel has also been categorized without any emphasis on revolution, as a novel "about the working classes and working-class life; perhaps with the intention of making propaganda". This different emphasis may reflect a difference between Russian, American and other traditions of working-class writing, with that of Britain. The British tradition was not especially inspired by the Communist Party, but had its roots in the Chartist movement, and socialism, amongst others. Furthermore, writing about the British working-class writers, H Gustav Klaus, in The Socialist Novel: Towards the Recovery of a Tradition (1982) suggested that "the once current [term] 'proletarian' is, internationally, on the retreat, while the competing concepts of 'working-class' and 'socialist' continue to command about equal adherence".The word proletarian is also used to describe works about the working class by working-class authors, to distinguish them from works by middle-class authors such as Charles Dickens (Hard Times), John Steinbeck (The Grapes of Wrath), and Henry Green (Living). Similarly, though some of poet William Blake's (1757–1827) works are early examples of working-class literature, including the two "The Chimney Sweeper" poems, published in Songs of Innocence in 1789 and Songs of Experience in 1794, which deal with the subject of child labour, Blake, whose father was a tradesman, was not a proletarian writer.
