From the middle decades of the 9th century until the Norman Conquest, East Anglia was an integral part of the Viking world which spanned the North Sea basin. Drawing on historical sources, archaeological sites, artefacts and place-names, Richard Hoggett explores the evidence for the Viking presence in East Anglia, from the initial campaign of the Great Heathen Army and the martyrdom of King Edmund, to the subsequent settlement and integration under the Danelaw, and the second wave of raids on the region which took place in the 11th century.
