Book excerpt: Æthelflæd (c. 870–918), political leader, military strategist, and administrator of law, is one of the most important ruling women in English history. Despite her multifaceted roles and family legacy, however, her reign and relationship with other women in tenth-century England have never been the subject of a book-length study. This interdisciplinary collection of essays redresses a notable hiatus in scholarship of early medieval England. Æthelflæd, Lady of the Mercians, and Women in Tenth-Century England argues for a reassessment of women’s political, military, literary, and domestic agency. It invites deeper reflection on the female kinships, networks, and communities that give meaning to Æthelflæd’s life, and through this shows how medieval history can invite new engagements with the past.
