This book investigates the agency and influence of medieval queens in late fourteenth-century England, focusing on the patronage and intercessory activities of the queens Philippa of Hainault and Anne of Bohemia, as well as the princess Joan of Kent. It examines the ways in which royal women were able to participate in traditional queenly customs such as intercession, and whether it was motherhood that gave power to a queen. This study focuses particularly on types of patronage, and also considers the importance of coronation, especially for Joan of Kent, who was neither a queen consort nor a dowager, yet still fulfilled some queenly duties. Crucially, the author highlights the transactional nature of the queen role at court, as she accumulated wealth from land, rights and traditions, which in turn funded patronage activities.
