*Entre rayonnement et réciprocité* is a scholarly volume on the history of cultural diplomacy, examining how states and institutions have used cultural exchange as a tool of international influence. The title frames the central tension of the subject: cultural diplomacy can project national prestige abroad while also relying on reciprocity, dialogue, and shared participation between communities. Through historical contributions, the work explores the institutions, practices, and intellectual contexts that shaped cultural diplomacy as a field of public action and international relations. It is useful for readers interested in diplomatic history, French and European cultural policy, and the broader role of culture in foreign affairs.
