The Anglo-Saxon king AEthelred 'the Unready' (978-1016) has long been considered to be inscrutable, irrational, and poorly advised. Infamous for his domestic and international failures, AEthelred was unable to fend off successive Viking raids, leading to the notorious St. Brice's Day Massacre in 1002, during which Danes in England were slaughtered on his orders. Though AEthelred's posthumous standing is dominated by his unsuccessful military leadership, his seemingly blind trust in disloyal associates, and his harsh treatment of political opponents, Roach suggests that AEthelred has been wrongly maligned. Drawing on extensive research, Roach argues that AEthelred was driven by pious concerns about sin, society, and the anticipated apocalypse. His strategies, in this light, were to honor God and find redemption.
