The international turn in intellectual history, which David Armitage announced in 2014, has evolved into a surge of publications on the global, international, and transnational aspects of the history of ideas. The migration of concepts around the world and moments of conceptual conjunction in history have attained growing attention from historians. Although methodological nationalism had never been the only option for writing the history of a specific country or society, it seems that now an international perspective is indispensable for explaining the political, cultural, or economic history of any given country. Historians seek to put their finger on the complex, dynamic moments which generate and reverberate influential ideas around the world. The patterns of relationship between different social, cultural, and political spheres, and the exchanges that lead to the evolution of ideas and concepts across national boundaries, have become increasingly appealing to historians of all creeds.
Udi Greenberg’s The Weimar Century: German Émigrés and the Ideological Foundations of the Cold War can be read as a contribution to this growing literature on international intellectual history.
