This collaborative collection provides fresh perspectives on Christianity and the conduct of war in medieval East Central Europe and Scandinavia, investigating the intersection between religion, culture, and warfare in territories that were only integrated into Christendom in the Central Middle Ages. The contributors analyze cultures that lay outside Charlemagne's limes and the frontiers of the Byzantine Empire, to consider a region stretching from the Balkans to the Baltic and Scandinavia. The volume considers clerics as military leaders and propagandists, the role of Christian ritual and doctrine in warfare, and the adaptation and transformation of indigenous military cultures. It uncovers new information on perceptions of war and analyzes how local practices were incorporated into clerical narratives, enabling the reader to achieve a complete understanding of the period.

In June 1219 Danish crusaders fought a vicious battle against local pagan warriors at the place in northern Estonia where Tallinn now lies. The battle—known then as the Battle of Lyndanise—was a narrow victory for the crusaders and eventually turned out to be a pivotal event in the national histories of both Denmark and Estonia as a milestone in the overall military conquest of the entire region by (mostly) western military powers. The main scope of this book is to present a study of this military conquest of Estonia around 1200 with a special focus on the Scandinavian involvement, enabling us to better understand the intense political, military, and religious changes that came to influence the region and its many people from the early high medieval period onwards.
