William of Malmesbury's Regesta Regum Anglorum (Deeds of the English Kings) is one of the great histories of England, and one of the most important historical works of the European Middle Ages. Although its focus is national, its scope encompasses most of Western Europe and beyond, providing a full-scale account of the First Crusade. Apart from its formidable learning, it is characterized by narrative skill and entertainment value - with topics including unpowered flight and Henry I's zoo. This edition in the Oxford Medieval Texts series is the first modern translation and edition. A full historical introduction is supplied in Volume II.
