In 878, Alfred king of Wessex was on the verge of oblivion. Trapped on a small island in the Somerset Levels, it seemed as if he and his kingdom were about to be destroyed. Yet within months he had defeated the Viking invaders and started to reverse the tide of conquest. While Alfred was driven by the prospect of a land that did not yet exist called England, he did not finally create it. Two of his children, Edward - king of Wessex after him - and his remarkable daughter thelfl d, the Lady of the Mercians, expanded his kingdom into Mercia in the Midlands. His grandson thelstan confirmed the conquest of the north at one of the great battles of the so-called Dark Ages at Brunanburh. The triumph of Alfred's dynasty was cemented by the short but magnificent reign of Edgar 'the Peaceable', a man who could claim to be not just king of England but emperor of the whole of Britain. The ultimate collapse of Anglo-Saxon England first of all in the face of the campaigns of Cnut of Denmark in 1015/6, and later the Norman Conquest of 1066, have unjustly obscured their achievements. This book tells their story and reasserts their right to be regarded as one of the greatest royal dynasties that England or Britain have ever seen.
