She is but a Woman, the first in-depth study of medieval Scottish queens, investigates the relationship between gender and power in the medieval Scottish court by exploring the art of queenship as practised by Joan Beaufort and Mary of Guelders, queens of James I and James II. These women were excluded from authority but clearly possessed power as wives and mothers of kings. They established and cultivated relationships with members of the court, learned about Scottish political life and supported their husbands in the business of government. The book examines for the first time the arrivals of Joan and Mary in Scotland, their social and political status, their relationships with their husbands and families, and their roles in international diplomacy. This modern re-evaluation of the role and power of the medieval queen is a thematic exploration rather than a biographical study. It situates the experiences of Joan and Mary within a broader European context and provides a new perspective on Scotland’s political, social and cultural links with Europe in the fifteenth century.
