'Overall, this book makes a valuable contribution to our understanding of noble power in the later Middle Ages. This book thus has plenty to offer historians interested in the nature of noble power in the medieval period, and how this played out during periods of sustained conflict.' Matthew Hefferan, Royal Studies Journal 'This book investigates the rulership of Jeanne de Penthičve (c.1326-1384), duchess of Brittany, and her struggle to maintain power in Brittany. Jeanne and her husband's rule are researched through the study of an outstanding range of printed and archival administrative and legal records. These sources are examined within a novel theoretical framework, challenging scholarly assumptions on the legitimacy of princely power, collaborative rule, and gendered power in fourteenth-century Europe. Significantly, Graham-Goering successfully demonstrates the crucial role of female rulership and lordship in the first phases of the Hundred Years' War in face of growing monarchical authority.' Royal Historical Society Gladstone Awards Committee ' this work is doubly interesting since Erika Graham-Goering fills a bibliographical gap by offering her readers a monograph devoted to a woman of power somewhat marginalized by the historiography, and at the same time providing keys to a better understanding of the functioning of princely and seigneurial institutions and political society in the fourteenth century.' Bertrand Schnerb, Francia-Recensio 'In all, her expert study and insightful reflections underscore the changing political and social conditions in the fourteenth century that permitted evolving and shifting power-sharing in the duchy of Brittany.' Diane E. Booton, The Medieval Review 'In this splendid book, Erika Graham-Goering provides a critical reassessment of the nature of political authority in later medieval France this important book provides a significant and timely reevaluation of princely power in the later Middle Ages and deserves to be read widely.' Neil Murphy, Speculum 'This book is a strong contribution to the study of late-medieval princely power. Its exploration of multiple kinds of sources (administrative, narrative, and visual examples such as seals) is also valuable to those interested in royal power as well as princely.' Kristin Bourassa, French History ' there is no doubt that the book is the result of an extremely important research achievement. In recent years, the reviewer has rarely read a work whose nuanced understanding of French or Breton 'political society' he could follow so fully.'
