Explores forgotten solidarity with African liberation struggles through the life of Black Chicagoan Prexy Nesbitt. For many civil rights activists, the Vietnam War brought the dangers of US imperialism and the global nature of antiracist struggle into sharp relief. Martha Biondi tells the story of one such group of activists who built an internationalist movement in Chicago committed to liberation everywhere but especially to ending colonialism and apartheid in Africa. Among their leaders was Prexy Nesbitt. Steeped from an early age in stories of Garveyism and labor militancy, Nesbitt was powerfully influenced by his encounters with the exiled African radicals he met in Dar es Salaam, London, and across the United States. Operating domestically and abroad, Nesbitt's cohort worked closely with opponents of Portuguese and white minority rule in Mozambique, Angola, and South Africa. Rather than promoting a US conception of Black self-determination, they took ideas from African anticolonial leaders and injected them into US foreign policy debates. The biography of a man but even more so of a movement, We Are Internationalists: Prexy Nesbitt and the Fight for African Liberation (U California Press, 2025) reveals the underappreciated influence of a transformative Black solidarity project.

Arise Africa, Roar China: Black and Chinese Citizens of the World in the Twentieth Century (University of North Carolina Press, 2021) explores the close relationships between three of the most famous twentieth-century African Americans, W. E. B. Du Bois, Paul Robeson, and Langston Hughes, and their little-known Chinese allies during World War II and the Cold War--journalist, musician, and Christian activist Liu Liangmo, and Sino-Caribbean dancer-choreographer Sylvia Si-lan Chen. Charting a new path in the study of Sino-American relations, Gao Yunxiang foregrounds African Americans, combining the study of Black internationalism and the experiences of Chinese Americans with a transpacific narrative and an understanding of the global remaking of China's modern popular culture and politics. Gao reveals earlier and more widespread interactions between Chinese and African American leftists than accounts of the familiar alliance between the Black radicals and the Maoist Chinese would have us believe. The book's multilingual approach draws from massive yet rarely used archival streams in China and in Chinatowns and elsewhere in the United States. These materials allow Gao to retell the well-known stories of Du Bois, Robeson, and Hughes alongside the sagas of Liu and Chen in a work that will transform and redefine Afro-Asia studies. Hettie V.

In this episode of International Horizons, RBI acting director Eli Karetny speaks with Alex Priou, Professor of Political Philosophy at the University of Austin, about how technology and ideology shape the modern soul. From Machiavelli’s “dikes and dams” to Odysseus’s struggle against the Sirens, Priou traces how modernity’s drive for control has left us materially fulfilled yet spiritually impoverished. The conversation explores liberalism’s crises, the moral stakes of AI, the American “technological republic,” and why revisiting Homer and Plato may be key to recovering wisdom and restraint in an age of restless innovation.

While decolonization liberated territories, it left the root causes of historical injustice unaddressed. Governance change did not address past wrongs and transferred injustice through political and financial architectures. In Calibrating Colonial Crime: Reparations and The Crime of Unjust Enrichment (Bristol University Press/Policy Press, 2024) Dr. Joshua Castellino presents a five-point plan aimed at system redress through reparations that addresses the colonially induced climate crisis through equitable and sustainable means. In highlighting the structural legacy of colonial crimes, Dr. Castellino provides insights into the complexities of contemporary societies, showing how legal frameworks could foster a fairer, more just world. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

One of The New Yorker’s Best Books of the Year A Washington Post Notable Book of the Year A Kirkus Reviews Best Book of the Year From an esteemed scholar, a richly textured, authoritative history of sex and sexuality in America—the first major account in three decades. Our era is one of sexual upheaval. Roe v. Wade was overturned in the summer of 2022, school systems across the country are banning books with LGBTQ+ themes, and the notion of a “tradwife” is gaining adherents on the right while polyamory wins converts on the left. It may seem as though debates over sex are more intense than ever, but as acclaimed historian Rebecca L. Davis demonstrates in Fierce Desires, we should not be too surprised, because Americans have been arguing over which kinds of sex are “acceptable”—and which are not—since before the founding itself.  From the public floggings of fornicators in early New England to passionate same-sex love affairs in the 1800s and the crackdown on abortion providers in the 1870s, and from the movements for sexual liberation to the recent restrictions on access to gender affirming care, Davis presents a sweeping, engrossing, illuminating four-hundred-year account of this nation’s sexual past. Drawing on a wealth of sources, including legal records, erotica, and eighteenth-century romance novels, she recasts important episodes—Anthony Comstock’s crusade against smut among them—and, at the same time, unearths stories of little-remembered pioneers and iconoclasts, such as an indentured servant in colonial Virginia named Thomas/Thomasine Hall, Gay Liberation Front cofounder Kiyoshi Kuromiya, and postwar female pleasure activist Betty Dodson.  At the heart of the book is Davis’s argument that the concept of sexual identity is relatively novel, first appearing in the nineteenth century. Over the centuries, Americans have shifted from understanding sexual behaviors as reflections of personal preferences or values, such as those rooted in faith or culture, to defining sexuality as an essential part of what makes a person who they are. And at every step, legislators, police, activists, and bureaucrats attempted to regulate new sexual behaviors, transforming government in the process. The most comprehensive account of America’s sexual past since John D’Emilio and Estelle Freedman’s 1988 classic, Intimate Matters, Davis’s magisterial work seeks to help us understand the turmoil of the present. It demonstrates how fiercely we have always valued our desires, and how far we are willing to go to defend them. Rebecca L. Davis is professor of History and of Women and Gender Studies at the University of Delaware where she held the Miller Family Endowed Early Career Professorship. She is the author of several books including Public Confessions: The Religious Conversions that Changed American Politics and More Perfect Unions: The American Search for Marital Bliss and is one of the co-founders and co-hosts of the podcast This is Probably a Weird Question about bodies, sexuality, health and history.

Do competitive elections secure democracy, or might they undermine it by breeding popular disillusionment with liberal norms and procedures? The so-called Italian School of Elitism, comprising Vilfredo Pareto, Gaetano Mosca, and Robert Michels, voiced this very concern. They feared that defining democracy exclusively through representative practices creates unrealistic expectations of what elections can achieve, generating mass demoralization and disillusionment with popular government. The Italian School’s concern has gone unheeded, even as their elite theory has been foundational for political science in the United States. Democratic Elitism: The Founding Myth of American Political Science (Harvard UP, 2025) argues that scholars have misinterpreted the Italians as conservative, antidemocratic figures who championed the equation of democracy with representative practices to restrain popular participation in politics. Natasha Piano contends not only that the Italian School’s thought has been distorted but also that theorists have ignored its main objective: to contain demagogues and plutocrats who prey on the cynicism of the masses. We ought to view these thinkers not as elite theorists of democracy but as democratic theorists of elitism. The Italian School’s original writings do not reject electoral politics; they emphasize the power and promise of democracy beyond the ballot. Elections undoubtedly are an essential component of functioning democracies, but in order to preserve their legitimacy we must understand their true capacities and limitations. It is past time to dispel the delusion that we need only elections to solve political crises, or else mass publics, dissatisfied with the status quo, will fall deeper into the arms of authoritarians who capture and pervert formal democratic institutions to serve their own ends.

This Is Not My World: Art and Public Spaces in Socialist Zagreb (U Minnesota Press, 2024) examines the Group of Six Authors—a collective of young artists who staged provocative art events in the public spaces of socialist Yugoslavia during the 1970s and early 1980s. The book analyses how these spaces, which had long been forums of state ideological control, were transformed into a contested terrain in which personal creativity and new identities could emerge. Drawing on artist interviews and extensive documentation, Adair Rounthwaite situates the Group's work within broader developments in conceptualism and avant-garde theory in the second half of the 20th century, offering a richly detailed account of this fascinating episode in global art history.

Since the first moment of conquest, colonizers and the colonized alike in Mexico confronted questions about what it meant to be from this place, what natural resources it offered, and who had the right to control those resources and on what basis. Focusing on the ways people, environment, and policies have been affected by political boundaries, in Rooted in Place: Botany, Indigeneity, and Art in the Construction of Mexican Nature, 1570–1914 (University of Arizona Press, 2025) historian Dr. Rick A. López explores the historical connections between political identities and the natural world. Dr. López analyzes how scientific intellectuals laid claim to nature within Mexico, first on behalf of the Spanish Empire and then in the name of the republic, during three transformative moments: the Hernández expedition of the late sixteenth century; the Royal Botanical Expedition of the late eighteenth century; and the heyday of scientific societies such as the Sociedad Mexicana de Historia Natural of the late nineteenth century. This work traces how scientific intellectuals studied and debated what it meant to know and claim the flora that sprang from Mexican soil—ranging from individual plants to forests and vegetated landscapes—and the importance they placed on indigeneity. It also points to the short- and long-term consequences of these efforts. Dr. López draws on archival and published sources produced from the sixteenth century through the start of the twentieth century and gives special attention to the use of visual images such as scientific illustrations and landscape art. López employs the term “visualization” in recognition of the degree to which officials, botanists, and draftsmen produced imagery and also how they and others viewed nature. Rooted in Place reveals how scientific endeavors were not just about cataloging flora but were deeply intertwined with the construction of identity and the political landscape at three pivotal moments in Mexican history. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

The Roman emperor Julian (r. 361-363 CE) was a man of action and of letters, which he employed in an effort to return the Empire to the light of the pagan gods, and reverse the Christianization of the empire advanced by his uncle Constantine and the sons of Constantine. This enterprise was inspired and guided by his conversion to the Neoplatonic philosophy and radical pagan Hellenism of Iamblichus and his disciples, and promoted by his production of Greek orations, letters, and satires. These works present a coherent vision of the providentially guided history and destiny of Rome as a series of foundations and refoundations enacted by rulers such as Romulus, Numa, and Caesar Augustus. As this book demonstrates, Julian offers an Iamblichean approach to the exegesis of the legends of Rome's founding, the allegories of Plato's dialogues, and myths of his own creation in order to articulate his own role in the refounding of the Empire. Furthermore, argues Jeremy Swist, approaching the wider examination of Julian's imperial self-image on these terms ends up nuancing and challenging common assumptions influenced by the rhetoric of his contemporary proponents. In his reverence for the gods and for philosophy, the emperor's self-construction embraces the identities of a statesman and soldier more than of a philosopher, of a Roman more than a Greek, and of a mere human rather than a semi-divine being. While distancing himself from the ideal models of philosophical virtue and imperial founding that inspire his own actions, he adopts a different set of exemplary figures as mirrors of himself.

An ecologist in California claimed that the iron laws of nature locked humanity into destroying our environment. This meant that we must take drastic measures to rein in unfettered capitalism and the American habit of overconsumption, lest we deplete our common resources. That argument made Garrett Hardin one of the most influential and celebrated environmentalists to ever live. Yet, he had a tragic view of the world that turned his green dream into a green nightmare. This is the final episode of Cited Podcast’s new season, Green Dreams. Green Dreams tells stories of radical environmental thinkers and their dreams for our green future. Should we make those dreams reality, or are they actually nightmares? For the rest of the episodes, visit the series page, and subscribe today (Apple, Spotify, RSS).

What do we mean when we talk about antisemitism? A thoughtful, vital new intervention from the award-winning historian. For most of history, antisemitism has been understood as a menace from Europe’s political Right, the province of blood-and-soil ethno-nativists who built on Christendom’s long-standing suspicion of its Jewish population and infused it with racist pseudo-science. Such threats culminated in the nightmare of Nazi Germany and the Holocaust. The landscape is very different now, as Mark Mazower argues in On Antisemitism: A Word in History (Penguin Press, 2025). More than four-fifths of the world’s Jews now live in Israel and the United States, with the former’s military dominance of its region guaranteed by the latter while the loudest voices decrying antisemitism see it coming from the Left not the Right. Mazower clearly and carefully shows us how we got here, seeking to illuminate rather than blame. Very few words have the punch of ‘antisemitism’ and yet no term is more liable to be misunderstood in ways affecting free speech and foreign policy alike. On Antisemitism is a vitally important attempt to draw a line that must be drawn. Mark Mazower is the Ira D. Wallach Professor of History at Columbia University.

Absolute Ethical Life: Aristotle, Hegel and Marx by Michael Lazarus Karl Marx gave us not just a critique of the political economy of capital but a way of confronting the impoverished ethical quality of life we face under capitalism. Interpreting Marx anew as an ethical thinker, Absolute Ethical Life provides crucial resources for understanding how freedom and rational agency are impacted by a social world formed by value under capitalism, with consequences for philosophy today. Michael Lazarus situates Marx within a shared tradition of ethical inquiry, placing him in close dialogue with Aristotle and Hegel. Lazarus traces the ethical and political dimensions of Marx's work missed by Hannah Arendt and Alasdair MacIntyre, two of the most profound critics of modern politics and ethics. Ultimately, the book claims that Marx's value-form theory is both a continuation of Aristotelian and Hegelian themes and at the same time his most distinctive theoretical achievement. In this normative interpretation of Marx, Lazarus integrates recent moral philosophy with a historically specific analysis of capitalism as a social form of life. He challenges contemporary political and economic theory to insist that any conception of modern life needs to account for capitalism. With a robust critique of capitalism derived from the determinations of what Marx calls the "form of value," Lazarus argues for an ethical life beyond capital. Michael Lazarus is a Lecturer in Political Theory in the Department of Political Economy. Before coming to King’s College London, he was Deakin University Postdoctoral Research Fellow at the Alfred Deakin Institute and a visiting Postdoctoral Fellow at Yale University.

Why is there no metric system in the United States? Why is it that a country known for its openness to the future, its scientific innovations, and its preference for practicality has not adopted the most practical, scientific, and innovative system of measurement? Yardstick Nation: The Metric System in America (Vanderbilt UP, 2025) by Dr. Hector Vera answers these questions by analyzing the political, economic, and international factors that determined the trajectory of the United States as a nation self-excluded from one of the most successful global technical languages. Using a historical-comparative approach and qualitative analysis of archival material, the book examines the trajectories of American scientists, engineers, politicians, and industrialists from 1787 to 1982, to detail what they wanted to attain and to explain what was actually possible to achieve given the political and economic conditions in which they lived. Yardstick Nation argues that in order to understand the unbreached distance between the United States and the metric system, we must consider the interaction between three structural elements: historical timing, state infrastructural power, and international economic integration. Dr. Vera’s systematic look at when and why countries have adopted the metric system shows that its introduction is never casual. In the countries that voluntarily embraced the metric system, this was the result of either deep internal political transformations or momentous changes in the international economy. When the adoption of the metric system is politically driven, it comes as the result of a social revolution, independence war, national unification, or the draft of a new constitution. When it is propelled by economic factors, metrication is part of the efforts of economically stagnant countries to integrate into international markets.

In the world of Black radical politics, the name Audley Moore commands unquestioned respect. Across the nine decades of her life, Queen Mother Moore distinguished herself as a leading progenitor of Black Nationalism, the founder of the modern reparations movement, and, from her Philadelphia and Harlem homes, a mentor to some of America's most influential Black activists.And yet, she is far less remembered than many of her peers and protégés—Marcus Garvey, Malcolm X, and Muhammad Ahmad, to name just a few—and the ephemera of her life are either lost or plundered. In Queen Mother: Black Nationalism, Reparations, and the Untold Story of Audley Moore (Pantheon, 2025), celebrated writer and historian Ashley D. Farmer restores Moore's faded portrait, delivering the first ever definitive account of her life and enduring legacy.Deeply researched and richly detailed, Queen Mother is more than just the biography of an American icon. It's a narrative history of 20th-century Black radicalism, told through the lens of the woman whose grit and determination sustained the movement.

Unleashing Black Power: Grassroots Organizing in Harlem and the Advent of the Long, Hot Summers (UVA Press, 2025) explores the local dynamics, national connections, and global context of the Black freedom movement in Harlem from 1954 to 1964, illuminating how activists, organizers, and ordinary people mounted their resistance to systemic racism in the Jim Crow North. The richness of Black radical thought and action in this period made Harlem a key battleground in the national civil rights movement, transformed local Black grassroots politics, and facilitated the rise of Black Power in New York City. At the same time, the city’s attempts to clamp down on activists revealed the repressive nature of Northern liberalism and heralded the expansion of the carceral state. Peter Blackmer argues that this decade of confrontations between Black communities and white state power caused Harlem residents and activists to seek “new means” for achieving freedom within a city, state, and nation determined to deny it. Tracing the dual evolution of Black radicalism and white resistance, Unleashing Black Power offers a new framework for analyzing the epochal urban uprisings in the 1960s. Guest: Peter Blackmer (he/him) is an associate professor of Africology and African American Studies at Eastern Michigan University and his research and teaching explore the ways in which Black-led grassroots organizing campaigns for self-determination in the 20th and 21st Century United States have shaped local and national politics through struggles for civil rights, human rights, and political power in American cities.

What does it mean to be a political subject? This is one of the key questions asked by Massimo Modonesi in ​The Antagonistic Principle: Marxism and Political Action (2019)​, published as part of the Historical Materialism book series from Brill and Haymarket books. The book takes on the theories of Marx and Gramsci to develop a philosophical triad of subalternity-antagonism-autonomy as a way of studying political subjectification under oppressive conditions and the potential for resistance. The book then looks at political developments in South and Latin America, trying to understand the underlying dynamics of both where it’s coming from, and what its possibilities are for anticapitalist resistance. Massimo Modonesi is professor and chair of the Political and Social Sciences Faculty at the Autonomous National University in Mexico, and is the author of numerous books on political theory and history in Latin America, his most recent in English being ​Subalternity, Antagonism, Autonomy: Constructing the Political Subject.​ He is a member of the coordinating committee of the International Gramsci Society.

How should one live? What should one do? And what do these questions have to do with being a good person? In Unbecoming Persons: The Rise and Demine of the Modern Moral Self (University of Chicago Press, 2025), Ladelle McWhorter reorients these questions through a genealogy of the concept of personhood. That genealogy is in the service of showing us not only that personhood is historically contingent, but that it is also optional. In unbecoming persons, we can feel relief, vital belonging, and exhilaration. We can also embrace an ethos of active belonging, a mode of living that eschews the trappings of personhood for the possibilities of life together. Learn more about your ad choices.

Calculus Reordered: A History of the Big Ideas (Princeton UP, 2019) takes readers on a remarkable journey through hundreds of years to tell the story of how calculus evolved into the subject we know today. David Bressoud explains why calculus is credited to seventeenth-century figures Isaac Newton and Gottfried Leibniz, and how its current structure is based on developments that arose in the nineteenth century. Bressoud argues that a pedagogy informed by the historical development of calculus represents a sounder way for students to learn this fascinating area of mathematics. Delving into calculus’s birth in the Hellenistic Eastern Mediterranean—particularly in Syracuse, Sicily and Alexandria, Egypt—as well as India and the Islamic Middle East, Bressoud considers how calculus developed in response to essential questions emerging from engineering and astronomy. He looks at how Newton and Leibniz built their work on a flurry of activity that occurred throughout Europe, and how Italian philosophers such as Galileo Galilei played a particularly important role. In describing calculus’s evolution, Bressoud reveals problems with the standard ordering of its curriculum: limits, differentiation, integration, and series. He contends that the historical order—integration as accumulation, then differentiation as ratios of change, series as sequences of partial sums, and finally limits as they arise from the algebra of inequalities—makes more sense in the classroom environment. Exploring the motivations behind calculus’s discovery, Calculus Reordered highlights how this essential tool of mathematics came to be. David M. Bressoud is DeWitt Wallace Professor of Mathematics at Macalester College and Director of the Conference Board of the Mathematical Sciences. His many books include Second Year Calculus and A Radical Approach to Lebesgue’s Theory of Integration. He lives in St. Paul, Minnesota.

The letters stemming from the First Crusade are premier sources for understanding the launch, campaign, and aftermath of the expedition. Between 1095 and 1100, epistles sustained social relationships across the Mediterranean and within Europe, as a mixture of historical writing, literary invention, news, and theological interpretation. They served ecclesiastical administration, projected authority, and formed focal points for spiritual commemoration and para-liturgical campaigns. Rewriting the First Crusade: Epistolary Culture in the Middle Ages (Boydell & Brewer, 2024) by Dr. Thomas Smith, is grounded on extensive research into the original manuscripts, and presents numerous new manuscript witnesses. The book argues that some of the letters are post hoc “inventions”, composed by generations of scribe-readers who visited crusading sites from the twelfth century on, adding new layers of meaning in the form of interpolations and post-scripts. Drawing upon this new understanding, and blurring the distinction of epistolary “reality”, it rewrites central aspects of the history of the First Crusade, considering the documents in a new way: as markers of enthusiasm and support for the crusade movement among monastic clergy, who copied and consumed them as a form of scribal crusading. Whether authentic letters or literary “confections”, they functioned as communal sites for the celebration, commemoration and memorialisation of the expedition. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.
