"To call this book ambitious is an understatement, yet it befits the author's breadth of knowledge.... Wu's comparative approach underscores the common challenges and strategies of nations navigating the complexities of frontier expansion."—Q. Edward Wang, Pacific Affairs --- "Wu skillfully draws China into a larger, truly global narrative about science, territory, and the making of the modern nation-state. In doing so, her work shines a new light on the wider legacies of science and empire, offering new tools for understanding the world in which we live today."—Judd Kinzley, American Historical Review --- "Birth of the Geopolitical Age is a valuable contribution to the literature on China's 19th- and 20th-century political, economic, and social development. Placing this country's history in an explicitly international perspective is justifiably important, in large part because of how Chinese leaders responded to the conditions they faced—and worked to achieve their goals—was significantly conditioned by intellectual work done in other countries, even those half a world away."—Graham F. Odell, The Developing Economies --- "Birth of the Geopolitical Age by Shellen Wu is an ambitious journey exploring the intellectual history of the evolution of geopolitics as a field of knowledge from the 1850s to the 1950s."—Sayantani Mukherjee, Isis: A Journal of the History of Science Society --- "Birth of the Geopolitical Age is both an intellectually stimulating and methodologically innovative study. It challenges readers to critically engage with the historical roots of modern geopolitical conflicts and the enduring legacies of imperial ideologies. Wu's work not only affirms the relevance of history in understanding today's geopolitical challenges but also invites scholars to reassess its complexities with renewed urgency and imagination."—Stefan Messingschlager, European Review of History --- "Birth of the Geopolitical Age seeks to disrupt the lines that have been drawn between empire and nation. To that end, Wu's notion of empire is elastic, extending beyond territorial sovereignty or even indirect governance."—Kate Merkel-Hess, Twentieth-Century China --- "Shellen Xiao Wu artfully packages a grand theory of 'geopolitical modernity' in detailed profiles of a colorful cast of characters, zooming in and out so both general readers and specialists can enjoy."—John Delury, Global Asia --- "In Birth of the Geopolitical Age, Wu addresses a lacuna in the study of geopolitics, namely, the social, political, cultural, and scientific contexts from which the concept of geopolitics emerged.... [H]er work pushes readers to consider how to think about global and world history, not just East Asian history.... Recommended."—M. J. Wert, CHOICE --- "Wu's comparative and multidisciplinary approach is commendable, skillfully combining the contributions of geographers, agronomists and lawyers with the concerns of Chinese intellectuals during this period and revealing areas of controversy that have remained in the shadows."—François Gipouloux, The China Quarterly --- "Shellen Wu has written an eye-opening study that centers China in the history of expansion into the great inland spaces by the world powers of the nineteenth and twentieth centuries. Readers will see the age of empire anew."—Charles S. Maier, Harvard University --- "By recounting the roles of academic disciplines and individual intellectuals in forming a spatial awareness of agricultural development and natural resource exploitation occurring in places distant from the corridors of power, Shellen Xiao Wu presents the pursuit of geopolitical power by economic and political elites through the construction of new forms of empire. Comparing and connecting her narrative of China's twentieth-century transformation with those in the U.S., Germany, and Japan, she offers a new global historical perspective on the emergence of China's contemporary importance."—R. Bin Wong, University of California, Los Angeles --- "Wu's Birth of the Geopolitical Age is the most exciting study in the history of science, empire, and nation I have read in recent years. The book is brilliantly conceptualized, tracing the circulation and translation of geographical and agricultural sciences among the United States, Germany, Japan, and particularly China. Its central idea, geo-modernity, is an illuminating concept that will be widely referenced. Based on extensive research in multiple languages, Birth of the Geopolitical Age tells a rich narrative about a wide range of historical actors, institutions, and discourses. The book is a marvel of scholarly ambition, erudition, and compression. Despite its impressive scope, the narrative is exceptionally clear and readable. This superb book is a model study in global and comparative history. I can't wait to recommend it to every historian interested in the topic."—Fa-ti Fan, Binghamton University
