Book excerpt: Volume 2 of The Cambridge History of Scandinavia provides a comprehensive and authoritative account of the Scandinavian countries from the close of the Middle Ages through to the formation of the nation states in the mid-nineteenth century. Beginning in 1520, the opening chapters of the volume discuss the reformation of the Nordic states and the enormous impact this had on the social structures, cultural identities and traditions of individual countries. With contributions from 38 leading historians, the book charts the major developments that unfolded within this crucial period of Scandinavian history. Chapters address topics such as material growth and the centralisation of power in the sixteenth and seventeenth centuries as well as the evolution of trade, foreign policy and client states in the eighteenth century. Volume 2 concludes by discussing the new economic and social orders of the nineteenth century in connection with the emergence of the nation states.
