The emergence of Naturalism does not mark a radical break with Realism, rather the new style is a logical extension of the old. The term was invented by Émile Zola partly because he was seeking for a striking platform from which to convince the reading public that it was getting something new and modern in his fiction. In fact, he inherited a good deal from his predecessors. Like Balzac and Flaubert, he created detailed settings meticulously researched, but tended to integrate them better into his narrative, avoiding the long set-piece descriptions so characteristic of earlier fiction. Again, like Balzac, he created a series of novels with linked characters and settings ("Les Rougon-Macquart: Histoire naturelle et sociale d'une famille sous le second Empire"--"The Rougon-Macquart: Natural and Social History of a Family During the Second Empire") which stretched to twenty novels. He tried to create a portrait of France in the 1880s to parallel the portrait Balzac had made of his own times in the Comédie humaine. Like Flaubert, he focussed on ordinary people with often debased motives.
