`David Stephenson's latest book is a bold commentary on historians' writings about the political and "socio-political" history of medieval Wales over the past fifty years. A deliberate challenge to traditional interpretations, it is supported, as befits an accomplished historian of Gwynedd and Powys, by a depth of scholarship reflected in annotations and bibliographies that amount to a quarter of the book.' -Emeritus Professor Ralph A. Griffiths, Swansea University ; `This is an invaluable contribution to the historiography of medieval Wales. Stephenson successfully challenges the enduring paradigm of the Gwynedd-led evolution of one Wales, and paints a more complex, multi-dimensional picture. An essential read for scholars and students of medieval Welsh history!' Dr Emma Cavell, Swansea University
