This is an impressively researched and convincingly argued book. This study demonstrates beyond all doubt the reality of what might be termed `l'exception belge'. Hilden's analysis provides the reader with a clear sense of the general movement of Belgian history in the nineteenth century. There are excellent chapters dealing with the First and Second International. This is a rich and rewarding book which by way of comparison helps us to reassess the history of labour in nineteenth-century France. Thoroughly recommended.
