By the 1850s the family had stabilized considerably after the disruption of the late eighteenth and early nineteenth centuries. With the consolidation caused by industrialization and urbanization, the growing middle classes created a distinctive middle-class lifestyle, which set them off from peasants, workers, and the aristocracy. New ideas about courtship and marriage, family and gender roles, and homemaking and child rearing expressed middle-class norms and values in ways that would have a profound impact on family life in the century to come. Changes in family life affected both men and women and all social classes, but to varying degrees. Leading a middle-class lifestyle was prohibitively expensive for workers and peasants, and middle-class family values at first had little relevance for their lives. Yet as the nineteenth century drew to a close, the middle-class lifestyle increasingly became the norm for all classes.
