In this seminal work, author Sverre Bagge provides a detailed account of Norwegian state formation in the period from c. 950 to 1350, widening his perspective to include a discussion of the emergence of the medieval state in the Middle Ages. The primary objective is to examine Norway as a case that may serve to illuminate some general problems of European state formation in the period, problems related both to the formation of the European system of independent kingdoms within a common cultural framework, and the inner development of these kingdoms. Furthermore, the book examines the changes that took place in the military, social-economical, ideological, legal, and administrative fields between the first formation of the kingdom and the early 14th century which, according to common opinion, represents a peak in the development of a Norwegian state. From Viking Stronghold to Christian Kingdom constitutes a vivid and compelling feat, offering a fresh and innovative approach to an important chapter in the history of Norway, while also casting new light on developments in the larger context of European history.
