offers a new interpretation of the history of the Silk Road, emphasizing its importance as a diplomatic route, rather than a commercial one. Tracing the arduous journeys of diplomatic envoys, Xin Wen presents a rich social history of long-distance travel that played out in deserts, post stations, palaces, and polo fields. The book tells the story of the everyday lives of diplomatic travelers on the Silk Road—what they ate and drank, the gifts they carried, and the animals that accompanied them—and how they navigated a complex web of geographic, cultural, and linguistic boundaries. It also describes the risks and dangers envoys faced along the way—from financial catastrophe to robbery and murder. Using documents unearthed from the famous Dunhuang “library cave” in Western China, paints a detailed picture of the intricate network of trans-Eurasian transportation and communication routes that was established between 850 and 1000 CE. By exploring the motivations of the kings who dispatched envoys along the Silk Road and describing the transformative social and economic effects of their journeys, the book reveals the inner workings of an interstate network distinct from the Sino-centric “tributary” system. In shifting the narrative of the Silk Road from the transport of commodities to the exchange of diplomatic gifts and personnel, puts the history of Eastern Eurasia in a new light.
