This publication explores the role of women as agents of diplomacy in the trans-Atlantic world since the early modern age. Chapters cover a wide range of geographical contexts, including Europe, Russia, Britain and the United States, and trace the diversity of women’s activities and the significance of their contributions. Through a selection of case studies, the book throws into new perspective the operations of political power in local and national domains, bridging and at times reconceptualising the relationship of the private to the public.
