Recent debates have used the concept of transnational history to broaden research on historical subjects that transcend national boundaries and encourage a shift away from official inter-state interactions to institutions, groups, and actors that have been obscured. This approach proves particularly fruitful for the dynamic field of global gender and women’s history. By looking at the restless lives and work of women’s activists in informal border-crossings, ephemeral NGOs, the lower management of established international organizations, and other global networks, this volume reflects the potential of a new perspective that allows for a more adequate analysis of transnational activities. By pointing out cultural hierarchies, the vicissitudes of translation and re-interpretation, and the ambiguity of intercultural exchange, this volume demonstrates the critical potential of transnational history. It allows us to see the limits of universalist and cosmopolitan claims so dear to many historical actors and historians.
