The Conquest of Plassans is the fourth novel in Émile Zola's twenty-volume series Les Rougon-Macquart. In many ways a sequel to the first novel in the cycle La Fortune des Rougon (1871) this novel is again centred on the fictional Provençal town of Plassans and its plot revolves around a sinister cleric's attempt at political intrigue with disastrous consequences for some of the townsfolk. Zola in this novel refers the fictional Provençal town from which the family sprang in The Fortune of the Rougons. In one of the most psychological of his novels Zola links small-town politics to the greater political and national dramas of the Second Empire.
