Æthelflæd (d. 918), Queen, administrator of law, military and political leader, is one of the most significant women in English history. Despite her multifaceted roles and family legacy, however, she has never been the subject of a book-length study. This interdisciplinary collection of essays redresses a notable hiatus in scholarship of early medieval England. It also examines Æthelflæd’s reign and legacy in the context of women’s roles during this period and so challenges a prevailing misconception that the tenth century represents a decline in female agency and power. Æthelflæd, Lady of the Mercians, and Women in Tenth-Century England argues for a reassessment of women’s political, military, literary and domestic agency.
