Women from the Ricasoli and Spinelli families formed a wide variety of social networks within and beyond Florence through their letters as they negotiated interpersonal relationships and lineage concerns to actively contribute to their families in early modern Italy. Women were located at the center of social networks through their work in bridging their natal and marital families, cultivating commercial contacts, negotiating family obligations and the demands of religious institutions, facilitating introductions for family and friends, and forming political patronage ties. This book argues that a network model offers a framework of analysis in which to deconstruct patriarchy as a single system of institutionalized dominance in early modern Italy. Networks account for female agency as an interactive force that shaped the kinships ties, affective relationships, material connections, and political positions of these elite families as women constructed their own narratives and negotiated their own positions in family life.
