This article takes literary representations of Cnut, the Danish conqueror of England, as a case study of the construction of English identity in the eleventh century. It traces representations of Cnut in four literary texts composed over the course of the century: the Anglo-Saxon Chronicle, the Knútsdrápur, the Encomium Emmae Reginae, and Osbern of Canterbury's Translatio Sancti Ælfegi. Each of these texts constructs a politically useful national—ethnic identity through the figure of Cnut, using the mechanisms of kingship, piety and devotion, language, place and literary tradition to work through the particular exigencies faced by the audiences that they seek to address.
