Cross and Scepter: Rise of the Scandinavian Kingdoms from the Vikings to the Reformation, by Sverre Bagge. Princeton, Princeton University Press, 2014. vi, 325 pp. $29.95 US (cloth). This volume is intended to be a short, synthetic history of the introduction of Christianity and the formation of in Scandinavia as well as microhistory of state formation and cultural change throughout Latin Christendom in the High Middle Ages. author, Sverre Bagge, covers the changes that took place in Denmark, Norway, and Sweden from the formation of the Three Kingdoms until the end of the Kalmar Union in the early sixteenth century. He explores the transition from Paganism to Christianity, the reception of European-style formal learning and the transformation of law and justice, military and administrative organization, social structure, political culture, and the division of power among the monarchy, aristocracy, common people, and the Church. Its approach is broad enough that it comes close to being a general history of medieval Scandinavia. A major theme of the book is the parallel development of the Scandinavian and other European states, for example Poland, Bohemia, and Hungary (pp. 36, 69, 77). Bagge begins the narrative in the Viking Age as the three arise out of a series of struggles between individual warlords. He emphasizes the apparently coincidental division between them, which had been established in the mid-eleventh century (p. 49). This sometimes leads to gaps, for instance he mentions Harald Bluetooth's boast about conquering Norway without comment (p. 31). further consolidation of the Scandinavian was intimately tied up with the introduction of Christianity. Bagge describes the development of church institutions, ecclesiastical law, royal legislative powers, and a court system: The rise of the ecclesiastical organization therefore forms an important part of the explanation for the stability of the three kingdoms (p. 83). debt to Joseph R. Strayer is notable, and openly acknowledged in the introduction (pp. 3-4). New military technology--heavy cavalry and castles--was also important, bringing a shift toward a more professional, elite army, and the evolution of the leding service obligation into a more fonnal tax (pp. 107-18). In his synthesis of those aspects, Bagge refers to the research of Charles Tilly (p. 4). Following this, Bagge turns to social and economic history, with an emphasis on social structures, royal and ecclesiastical revenues, and the growth of towns and trade. He describes the gradual development of bureaucracies and courts, and the division of power between monarchy, aristocracy, and the church. While the secular and ecclesiastical aristocracy controlled most of the revenues of the three countries, Bagge shows how individual kings could exploit the competition between them to achieve greater power than indicated by the modest resources under their direct control. He also looks at the issue of medieval nationalism, a hotly contested topic among modern scholars. …
