Section one of this volume categorizes basic types of personal bonds, both vertical and horizontal, while section two charts patterns of local, regional and transnational elite networks from wide-scope, longitudinal perspectives. Finally, the third section turns to case-studies of networks in action, analyzing strategies and transactions implied by uses of social resources in specific micro-political settings. A concluding chapter discusses how social power in the North compared to wider European experiences. A wide range of sources and methodologies is applied to reveal how networks were established, maintained, and put to use – and how they transformed in processes of centralizing power and formalizing hierarchies. The engagement with and analysis of intriguing primary source material has produced a key teaching tool for instructors and essential reading for students interested in the workings of medieval Scandinavia, elite class structures, and Social and Political History more generally.
