Jewish women in medieval Europe wielded remarkable influence as educators, businesswomen, and preservers of faith, yet their stories remain largely buried beneath male-centered historical accounts. Through careful analysis of Hebrew chronicles, rabbinic literature, and archival records, including Rabbi Eleazar of Worms' poignant eulogy for his wife Dulcia, a complex portrait emerges of women who transcended traditional domestic roles. These women served as children's primary religious instructors, engaged actively in moneylending and textile production, and demonstrated extraordinary courage during periods of persecution, particularly the Crusade massacres. While operating under different social constraints than their Christian contemporaries - lacking access to institutions like nunneries - Jewish women forged alternative paths for religious expression and economic participation. The eulogy for Dulcia exemplifies how women could simultaneously embody pietistic ideals while maintaining practical economic and educational responsibilities. A comparative framework with Christian women's experiences reveals how Jewish women's unique circumstances shaped their contributions to family survival, religious continuity, and community resilience during crisis, though their vital roles remain underrepresented in traditional historical narratives. This research addresses a critical gap in medieval Jewish historiography by reconstructing women's social, economic, and religious activities through limited but revealing historical sources.
