In the years which followed the Norman Conquest, the Old English aristocracy was largely deprived of its lands and offices, both lay and ecclesiastical. The resistance of the English nobility to the Norman Conquest made a large contribution to its own eclipse, but it is rarely that we are afforded a glimpse of the fortunes of an individual. The historian may, however, dwell in some detail on the career of one man, Edgar the Ætheling. Episodes from his life are preserved in a variety of works composed in the eleventh and twelfth centuries. The Anglo-Saxon Chronicle contains several entries relating to his activities after 1066, and the D version shows a special interest in Edgar and his family. Among Latin histories, those of John of Worcester, William of Malmesbury and Orderic Vitalis follow his activities, although none of these authors was well informed about his life. Edgar appears not to have made a strongly favourable impression upon any of them: to the anonymous compilers of the Anglo-Saxon Chronicle he was the rightful heir to the throne of England, but to both William and Orderic he was indolent. There is little difficulty involved in bringing together the known episodes of his life, and although his royal blood makes him a far from typical example the picture that emerges gives a useful insight into how one Englishman fared in the unstable political climate of the years immediately preceding the Norman Conquest, and in its aftermath. It is intended here to assemble the evidence for the life of Edgar and to treat him not as a footnote to history, which is how he has often fared at the hands of historians, but as a character of no small importance in the history of the Norman Conquest of England.
