The first volume of Sir George Clark's Oxford History of England was published in 1934. Over the following 50 years that series established itself as a standard work of reference, and a repertoire of scholarship. The New Oxford History of England, of which this is the first volume, is its successor. Each volume will set out an authoritative view of the present state of scholarship, presenting a distillation of the knowledge built up by a half-century's research and publication of new sources, and incorporating the perspectives and judgements of modern scholars.
