This nonfiction study examines the economic development of Nord-Pas-de-Calais during the second half of the twentieth century, a period marked by deep industrial change. Focusing on a region long associated with coal, textiles, steel, and heavy manufacturing, the work traces how production structures, employment patterns, and social conditions evolved as older industries declined and new economic priorities emerged. It considers the relationship between local labor markets, public policy, and regional transformation, offering a grounded account of how economic decisions shaped communities across Nord-Pas-de-Calais. The book is useful for readers interested in French regional history, industrial policy, and the social consequences of economic restructuring.
