A sweeping germ’s-eye view of history from human origins to global pandemics Plagues upon the Earth is a monumental history of humans and their germs. Weaving together a grand narrative of global history with insights from cutting-edge genetics, Kyle Harper explains why humanity’s uniquely dangerous disease pool is rooted deep in our evolutionary past, and why its growth is accelerated by technological progress. He shows that the story of disease is entangled with the history of slavery, colonialism, and capitalism, and reveals the enduring effects of historical plagues in patterns of wealth, health, power, and inequality. He also tells the story of humanity’s escape from infectious disease—a triumph that makes life as we know it possible, yet destabilizes the environment and fosters new diseases. Panoramic in scope, Plagues upon the Earth traces the role of disease in the transition to farming, the spread of cities, the advance of transportation, and the stupendous increase in human population. Harper offers a new interpretation of humanity’s path to control over infectious disease—one where rising evolutionary threats constantly push back against human progress, and where the devastating effects of modernization contribute to the great divergence between societies. The book reminds us that human health is globally interdependent—and inseparable from the well-being of the planet itself. Putting the COVID-19 pandemic in perspective, Plagues upon the Earth tells the story of how we got here as a species, and it may help us decide where we want to go.

When Rome was at its height, an emperor s male beloved, victim of an untimely death, would be worshipped around the empire as a god. In this same society, the routine sexual exploitation of poor and enslaved women was abetted by public institutions. Four centuries later, a Roman emperor commanded the mutilation of men caught in same-sex affairs, even as he affirmed the moral dignity of women without any civic claim to honor. The gradual transformation of the Roman world from polytheistic to Christian marks one of the most sweeping ideological changes of premodern history. At the center of it all was sex. Exploring sources in literature, philosophy, and art, Kyle Harper examines the rise of Christianity as a turning point in the history of sexuality and helps us see how the roots of modern sexuality are grounded in an ancient religious revolution.

While Roman sexual culture was frankly and freely erotic, it was not completely unmoored from constraint. Offending against sexual morality was cause for shame, experienced through social condemnation. The rise of Christianity fundamentally changed the ethics of sexual behavior. In matters of morality, divine judgment transcended that of mere mortals, and shame a social concept gave way to the theological notion of sin. This transformed understanding led to Christianity s explicit prohibitions of homosexuality, extramarital love, and prostitution. Most profound, however, was the emergence of the idea of free will in Christian dogma, which made all human action, including sexual behavior, accountable to the spiritual, not the physical, world."

How devastating viruses, pandemics, and other natural catastrophes swept through the far-flung Roman Empire and helped to bring down one of the mightiest civilizations of the ancient world Here is the monumental retelling of one of the most consequential chapters of human history: the fall of the Roman Empire. The Fate of Rome is the first book to examine the catastrophic role that climate change and infectious diseases played in the collapse of Rome's power-a story of nature's triumph over human ambition. Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. The Fate of Rome is a sweeping account of how one of history's greatest civilizations encountered and endured, yet ultimately succumbed to, the cumulative burden of nature's violence.

Capitalizing on the rich historical record of late antiquity, and employing sophisticated methodologies from social and economic history, this book reinterprets the end of Roman slavery. Kyle Harper challenges traditional interpretations of a transition from antiquity to the Middle Ages, arguing instead that a deep divide runs through 'late antiquity', separating the Roman slave system from its early medieval successors. In the process, he covers the economic, social and institutional dimensions of ancient slavery and presents the most comprehensive analytical treatment of a pre-modern slave system now available. By scouring the late antique record, he has uncovered a wealth of new material, providing fresh insights into the ancient slave system, including slavery's role in agriculture and textile production, its relation to sexual exploitation, and the dynamics of social honor. By demonstrating the vitality of slavery into the later Roman empire, the author shows that Christianity triumphed amidst a genuine slave society.

A sweeping new history of how climate change and disease helped bring down the Roman Empire Here is the monumental retelling of one of the most consequential chapters of human history: the fall of the Roman Empire. The Fate of Rome is the first book to examine the catastrophic role that climate change and infectious diseases played in the collapse of Rome's power--a story of nature's triumph over human ambition. Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. He takes readers from Rome's pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted. Harper describes how the Romans were resilient in the face of enormous environmental stress, until the besieged empire could no longer withstand the combined challenges of a "little ice age" and recurrent outbreaks of bubonic plague. A poignant reflection on humanity's intimate relationship with the environment, The Fate of Rome provides a sweeping account of how one of history's greatest civilizations encountered, endured, yet ultimately succumbed to the cumulative burden of nature's violence. The example of Rome is a timely reminder that climate change and germ evolution have shaped the world we inhabit--in ways that are surprising and profound.

All Americans, liberal or conservative, religious or not, can agree that religious freedom, anchored in conscience rights, is foundational to the U.S. democratic experiment. But what freedom of conscience means, what its scope and limits are, according to the Constitution - these are matters for heated debate. At a moment when such questions loom ever larger in the nation's contentious politics and fraught policy-making process, this timely book offers invaluable historical, empirical, philosophical, and analytical insight into the American constitutional heritage of religious liberty. As the contributors to this interdisciplinary volume attest, understanding religious freedom demands taking multiple perspectives. The historians guide us through the legacy of religious freedom, from the nation's founding and the rise of public education, through the waves of immigration that added successive layers of diversity to American society. The social scientists discuss the swift, striking effects of judicial decision making and the battles over free exercise in a complex, bureaucratic society. Advocates remind us of the tensions abiding in schools and other familiar institutions, and of the major role minorities play in shaping free exercise under our constitutional regime. And the jurists emphasize that this is a messy area of constitutional law. Their work brings out the conflicts inherent in interpreting the First Amendment - tensions between free exercise and disestablishment, between the legislative and judicial branches of government, and along the complex and ever-shifting boundaries of religion, state, and society. What emerges most clearly from these essays is how central religious liberty is to America's civic fabric - and how, under increasing pressure from both religious and secular forces, this First Amendment freedom demands our full attention and understanding.
