This volume offers a comparative approach to the crusades outside the Holy Land, focusing on Iberia and the Baltic region. The two theatres of war shared a number of characteristics such as the longevity and nature of the ongoing warfare to which the crusade ideas were applied. This comparative study thus throws further light not only onto events in the two regions but also onto the development of the crusade movement in general. The volume focus on four themes, namely the historiography of the Iberian and Baltic crusades; the transfer of crusading ideas from the Holy Land to Iberia and the Baltic region and the use of these ideas in local rhetoric and propaganda; the papal attitudes towards these campaigns; and co-existence and interaction between conquered and conquerors as reflected in the art and architecture of the Iberian and Baltic regions. The book is a resource for both undergraduates and postgraduates.
