Berengaria of Navarre was queen of England (1191-99) and lord of Le Mans (1204-30), but has received little attention in terms of a fully encompassing biography from Navarrese, Anglophone, and French perspectives. This book explores her political career whilst utilising the surviving documentation to demonstrate her personal and familial partnerships and life as a dowager queen. This biography follows Berengaria's journey from a Navarrese infanta, raised in the northern Iberian kingdom, to her travels across Europe to marriage and the Third Crusade, venturing through Sicily, Cyprus, and on to the Holy Land in 1191. Berengaria's reign and early years as dowager queen are examined in the context of the Anglo-French conflict and domestic disputes, before her decision to negotiate with the king of France, Philip Augustus, and become lord of Le Mans, for which she is far better known in local memory. The volume flows chronologically discussing her roles as infanta, queen, dowager, and lord, and is an ideal resource for scholars and those interested in the history of gender, queenship, lordship, and Western Europe in the twelfth and thirteenth centuries.
