This volume contains the proceedings of a conference held in Oslo in late 2005, which brought together scholars working in a wide variety of disciplines from Scandinavia, Great Britain and Ireland. The papers here began as those read at the conference, augmented by two written immediately after by attendees, but have been updated in light of the discussions in Oslo and more recent scholarship. They offer historical, archaeological, art-historical, religious-historical and philological views of the interaction and interdependence of Celtic and Norse populations in the Irish Sea region in the period 800 A.D.-1200 A.D. Contributors are Ian Beuermann, Barbara Crawford, Claire Downham, Fiona Edmonds, Colman Etchingham, Zanette T. Glorstad, John Hines, Alan Lane, Julie Lund, Jan Erik Rekdal and David Wyatt.

A seminal biography of the underappreciated eleventh-century Scandinavian warlord-turned-Anglo-Saxon monarch who united the English and Danish crowns to forge a North Sea empire Historian Timothy Bolton offers a fascinating reappraisal of one of the most misunderstood of the Anglo-Saxon kings: Cnut, the powerful Danish warlord who conquered England and created a North Sea empire in the eleventh century. This seminal biography draws from a wealth of written and archaeological sources to provide the most detailed accounting to date of the life and accomplishments of a remarkable figure in European history, a forward-thinking warrior-turned-statesman who created a new Anglo-Danish regime through designed internationalism.
