The Godwin dynasty dominated English politics for more than forty years. Earl Godwin established himself as Cnut's most senior advisor, and continued that role under Edward the Confessor, seeing his daughter Edith become queen and his two eldest sons Swegn and Harold given earldoms. After Godwin's death four of his sons held earldoms, and Harold was to emerge as Edward the Confessor's senior earl and eventually succeed as king of England.

This book considers all the key events throughout this period, including Godwin's emergence, his involvement in the succession dispute after Cnut's death, the rise to prominence of his eldest children, the family's exile and dramatic return, the quarrel between Harold and Tostig, and the Norse and Norman invasions. Specific chapters have been devoted to Harold's trip to Normandy and William of Normandy's claims to the English throne, re-assessments of the accepted Norman landing site and traditional site of the battle of Hastings, and the fate of the surviving members of the dynasty post-1066.

Over a period of nearly fifty years the house of Godwin had established itself as the most influential and powerful dynasty in Anglo-Saxon England. It took only months for it to fall.
