Exchanges: A Cambridge UP Podcast

Julius Caesar was no aspiring autocrat seeking to realize the imperial future but an unusually successful republican leader who was measured against the Republic's traditions and its greatest heroes of the past. Catastrophe befell Rome not because Caesar (or anyone else) turned against the Republic, its norms, and institutions, but because Caesar's extraordinary success mobilized a determined opposition that ultimately preferred to precipitate civil war rather than accept its political defeat. Based on painstaking re-analysis of the ancient sources in the light of recent advances in our understanding of the participatory role of the People in the republican political system, a strong emphasis on agents' choices rather than structural causation, and profound skepticism toward the facile determinism that often substitutes for historical explanation, Julius Caesar and the Roman People (Cambridge University Press, 2021) offers a radical reinterpretation of a figure of profound historical importance who stands at the turning point of Roman history from Republic to Empire.Robert Morstein-Marx is Professor of Classics at the University of California, Santa Barbara.

In An Urban History of China (Cambridge UP, 2021), Toby Lincoln offers the first history of Chinese cities from their origins to the present. Despite being an agricultural society for thousands of years, China had an imperial urban civilization. Over the last century, this urban civilization has been transformed into the world's largest modern urban society. Throughout their long history, Chinese cities have been shaped by interactions with those around the world, and the story of urban China is a crucial part of the history of how the world has become an urban society. Exploring the global connections of Chinese cities, the urban system, urban governance, and daily life alongside introductions to major historical debates and extracts from primary sources, this is essential reading for all those interested in China and in urban history.

How do states advance their national security interests? Conventional wisdom holds that states must court the risk of catastrophic war by “tying their hands” to credibly protect their interests. Dan Reiter overturns this perspective with the compelling argument that states craft flexible foreign policies to avoid unwanted wars. Through a comprehensive analysis of key international crises, including the Berlin, Taiwan Straits, and Cuban Missile Crises, and the Korean and Vietnam Wars, Reiter provides new perspectives on the causes of wars, the role of international alliances, foreign troop deployments, leader madness, and the impact of AI on international relations. With critical insights into contemporary foreign policy challenges, such as America’s role in NATO, the risks of war with China, containing a resurgent Russia, and the dangers of nuclear war, Untied Hands: How States Avoid the Wrong Wars (Cambridge University Press, 2025) is essential reading for anyone interested in understanding how states can effectively manage international crises while avoiding the wrong wars. Dan Reiter is Samuel Candler Dobbs Professor of Political Science at Emory University. Leo Bader is a senior at Wesleyan University studying political theory and history.

The term “Heimat,” referring to a local sense of home and belonging, has been the subject of much scholarly and popular debate following the fall of the Third Reich. Countering the persistent myth that Heimat was a taboo and unusable term immediately after 1945, Geographies of Renewal uncovers overlooked efforts in the aftermath of the Second World War to conceive of Heimat in more democratic, inclusive, and pro-European modes. It revises persistent misconceptions of Heimat as either tainted or as a largely reactionary idea, revealing some surprisingly early identifications between home and democracy. Jeremy DeWaal further traces the history of efforts to eliminate the concept, which first emerged during the Cold War crisis of the early 1960s, and reassesses why so many on the political left sought to re-engage with Heimat in the 1970s and 1980s. This revisionist history intervenes in larger contemporary debates, asking compelling questions surrounding the role of the local in democracy, the value of community, and the politics of place attachments. Guest: Jeremy DeWaal (he/him), is Lecturer in European History at the University of Exeter. His research focuses on German cultural history, spatial history, memory, and the history of emotions. DeWaal’s work on Heimat and democracy has been supported by the Alexander von Humboldt Foundation, the German Academic Exchange Service, the Central European History Society, and the Berlin Programme at the Free University of Berlin. Host: Jenna Pittman (she/her), a Ph.D. student in the Department of History at Duke University. She studies modern European history, political economy, and Germany from 1945-1990.

In the book Monopolizing Knowledge: The East India Company and Britain’s Second Scientific Revolution (Cambridge UP, 2025), author Jessica Ratcliff traces the changing practices of knowledge accumulation and management at the British East India Company, focusing on the Company’s library, museum, and colleges in Britain. Although these institutions were in Britain, they were funded by taxes from British India and they housed, so it was argued, the “national” collections of British India. The book examines how these institutions emerged from the Company’s unique form of monopoly-based colonial capitalism. It then argues that this “Company science” would go on to shape and eventually become absorbed into Britain’s public (i.e. state-funded) science in the later nineteenth century. Soumyadeep Guha is a PhD candidate in the History Department at the State University of New York, Binghamton, with research interests in Agrarian History, the History of Science and Technology, and Global History, focusing on 19th and 20th century India. His MA dissertation, War, Science and Survival Technologies: The Politics of Nutrition and Agriculture in Late Colonial India, explored how wartime imperatives shaped scientific and agricultural policy during the Second World War in India. Currently, his working on his PhD dissertation on the histories of rice and its production between colonial and early post-colonial Bengal, examining the entangled trajectories of agrarian change, scientific knowledge, and state-making.

The apostle Paul was a Jew. He was born, lived, undertook his apostolic work, and died within the milieu of ancient Judaism. And yet, many readers have found, and continue to find, Paul's thought so radical, so Christian, even so anti-Jewish – despite the fact that it, too, is Jewish through and through. This paradox, and the question how we are to explain it, are explored in Matthew Novenson's Paul and Judaism at the End of History (Cambridge UP, 2024). The solution, according to Novenson, lies in Paul's particular understanding of time. This too is altogether Jewish, with the twist that Paul sees the end of history as present, not future. In the wake of Christ's resurrection, Jews are perfected in righteousness and – like the angels – enabled to live forever, in fulfilment of God's ancient promises to the patriarchs. What is more, gentiles are included in the same pneumatic existence promised to the Jews. This peculiar combination of ethnicity and eschatology yields something that looks not quite like Judaism or Christianity as we are used to thinking of them.

Martin Luther - monk, priest, intellectual, or revolutionary - has been a controversial figure since the sixteenth century. Most studies of Luther stress his personality, his ideas, and his ambitions as a church reformer. In Luther, Conflict, and Christendom: Reformation Europe and Christianity in the West (Cambridge UP, 2018), Christopher Ocker brings a new perspective to this topic, arguing that the different ways people thought about Luther mattered far more than who he really was. Providing an accessible, highly contextual, and non-partisan introduction, Ocker says that religious conflict itself served as the engine of religious change. He shows that the Luther affair had a complex political anatomy which extended far beyond the borders of Germany, making the debate an international one from the very start. His study links the Reformation to pluralism within western religion and to the coexistence of religions and secularism in today's world.

Challenging the geographical narrative of the history of Islam, Chiara Formichi’s new book Islam and Asia: A History (Cambridge University Press, 2020), helps us to rethink how we tell the story of Islam and the lived expressions of Muslims without privileging certain linguistic, cultural, and geographic realities. Focusing on themes of reform, political Islamism, Sufism, gender, as well as a rich array of material culture (such as sacred spaces and art), the book maps the development of Islam in Asia, such as in Kashmir, Indonesia, Malaysia, and China. It considers both transnational and transregional ebbs and flows that have defined the expansion and institutionalization of Islam in Asia, while attending to factors such as ethnicity, linguistic identity and even food cultures as important realities that have informed the translation of Islam into new regions. It is the “convergence and conversation” between the “local” and “foreign” or better yet between the theoretical notions of “centre” and “periphery” of Islam and Muslim societies that are dismantled in the book, defying any notions of Asian expressions of Islam as a “derivative reality.” The book is accessibly written and will be extremely useful in any undergraduate or graduate courses on Islam, Islam in Asia, or political Islam. The book will also be of interest to those who work on Islamic Studies and Asia Studies.Shobhana Xavier is an Assistant Professor of Religious Studies at Queen’s University.

Joseph Gfroerer spent nearly 40 years working as a statistician for the National Institute on Drug Abuse (NIDA) and the Substance Abuse and Mental Health Services Administration (SAMHSA). Starting in 1988, when the American drug war was taking its current shape, he led the National Survey on Drug Use and Health (NSDUH), one of the federal government’s largest and most important ongoing health surveys that tracks Americans’ use of illegal drugs, prescription drugs, alcohol and tobacco. War Stories from the Drug Survey: How Culture, Politics, and Statistics Shaped the National Survey on Drug Use and Health (Cambridge UP, 2018), written after he retired, shows where the survey came from, details how it gathers information, and tracks the impact that the shifting cultural and political climate surrounding drug use played on how these statistics were understood. Gfroerer provides necessary insight on what drug use statistics have meant, how they’ve been used (and misused), and what this means for our understanding of drug use in America today.Emily Dufton is the author of Grass Roots: The Rise and Fall and Rise of Marijuana in America (Basic Books, 2017). A drug historian and writer, her second book, on the development of the opioid addiction medication industry, is under contract with the University of Chicago Press.

Emerging from an award-winning article in International Security, China's Gambit examines when, why, and how China attempts to coerce states over perceived threats to its national security. Since 1990, China has used coercion for territorial disputes and issues related to Taiwan and Tibet, yet China is curiously selective in the timing, target, and tools of coercion. This book offers a new and generalizable cost-balancing theory to explain states' coercion decisions. It demonstrates that China does not coerce frequently and uses military coercion less when it becomes stronger, resorting primarily to non-militarized tools. Leveraging rich empirical evidence, including primary Chinese documents and interviews with Chinese and foreign officials, this book explains how contemporary rising powers translate their power into influence and offers a new framework for explaining states' coercion decisions in an era of economic interdependence, particularly how contemporary global economic interdependence affects rising powers' foreign security policies.
