"I read a lot of history in my spare time, and as best I can tell modern scholarship is telling us that Rome really was something special. What I learned from Peter Temin, and at greater length from Kyle Harper, was that Rome wasn鈥檛 your ordinary pre-industrial economy. . . . Harper notes that Rome was held back in some ways by a heavy burden of disease, an unintentional byproduct of urbanization and trade that a society lacking the germ theory had no way to alleviate. But still, the Romans really did achieve remarkable things on the economic front."鈥擯aul Krugman, New York Times
"A work of remarkable erudition and synthesis, Harper鈥檚 timely study offers a chilling warning from history of 'the awesome, uncanny power of nature'."鈥擯. D. Smith, The Guardian
"Original and ambitious. . . . [Harper] provide[s] a panoramic sweep of the late Roman Empire as interpreted by one historian's incisive, intriguing, inquiring mind."鈥擩ames Romm, Wall Street Journal
"Ingenious, persuasive. . . . Lucidly argued."鈥�Publishers Weekly
"A view of the fall of Rome from a different angle, looking beyond military and social collapse to man's relationship to the environment. There is much to absorb in this significant scholarly achievement, which effectively integrates natural, social, and humanistic sciences."鈥�Kirkus
"An excellent new book. . . . [Harper] has managed a prodigious scholarly output that uses date-driven, twenty-first-century methods to solve enduring problems of ancient history."鈥擭oel Lenski, Times Literary Supplement
"[A] sweeping retelling of the rise and fall of an empire, [that] was brought down as much by 鈥榞erms as by Germans.'"鈥擪eith Johnson, Foreign Policy
"This beautifully written book is ground-breaking stuff, both for its method and content, and one of the most important of the year."鈥擜drian Spooner, Classics for All
"Harper argues his case brilliantly, with deep scientific research into weather, geology and disease."鈥擧arry Mount, The Spectator
"An ambitious and convincing reappraisal of one of the most studied episodes of decline and fall in human history."鈥擡llie Robins, Los Angeles Review of Books
"Beautifully and often wittily written, this is history that has some of the impact of a great work of dystopian science fiction."鈥擳om Holland, BBC History Magazine
"Harper鈥檚 focus is resolutely historical, dealing only glancingly with modern climate concerns. But the book鈥檚 theme is essentially a timeless one: how big, complex societies handle strain and shocks from factors outside of their control. That gives it some relevance to the challenges we face today. . . . If the Fate of Rome proves anything, it鈥檚 that nature always has the last laugh."鈥擜sher Elbein, Earther.com
"Harper offers a striking reinterpretation with worrisome implications for the present day. . . . Today, we inhabit a global system with a very similar combination of climatologic disturbances, urbanization, less diverse diets, and globalization. Ancient history reveals the risks we run."鈥擜ndrew Moravcsik, Foreign Affairs
"The Fate of Rome is one of the most immediately readable histories of the year, always investing even the most well-known subjects with the vigor of fresh perspective."鈥擲teve Donoghue, Open Letters Monthly
"A recent book makes a convincing case that we need to be more cognizant of the natural world鈥檚 role in all this. The Fate of Rome: Climate, Disease and the End of An Empire, by the University of Oklahoma鈥檚 Kyle Harper, makes a strong argument for the role of plague and a shifting climate in the confluence of political, economic, and social processes that we label the fall of the Roman Empire."鈥擯atrick Wyman, Deadspin
"Drawing on cutting-edge research into ice cores, cave stones, lake deposits, and other sediments, Harper explores the influence of the changing climate on Rome鈥檚 history. With a storyteller鈥檚 flair, he describes how the climate鈥檚 impact was by turns subtle and overwhelming, alternately constructive and destructive, but that the changing climate was ultimately a 鈥榳ild card鈥� that transcended all the other rules of the game. . . . Harper reveals how the fate of Rome was decided not just by emperors, soldiers, and barbarians, but also by climate instability and pernicious disease."鈥擫ucia Marchini, World Archaeology
"[Harper's] aim in The Fate of Rome, however, is to foreground one class of explanations that has hitherto been relatively neglected by historians: the influence of climate and disease. Such explanations are not new, but Harper brings to the table a large body of recent scientific research into the evolution of ancient diseases, disease ecology and historical climate variations. . . . The wealth of new detail Harper offers to support his general theses is the true strength of his book."鈥擩effrey Mazo, Survival
"This is an exciting book that provides a fresh look at a perennial topic, the fall of the Roman Empire, in sparkling prose accessible to all economic historians. . . . Others interested in plagues will find time lines and stories to ground the biology in its Roman context. And anyone who is attempting to use the fall of the Roman Empire as an example in contemporary life should read this book before expounding one or another outmoded theory of the fall of the Roman Empire."鈥擯eter Temin, EH.net
"Harper has produced a wonderful case study that demands a general rethinking of how we view the decline and fall of the Roman Empire."鈥擶illiamson Murray, The Strategy Bridge
"T]he author takes pains not to descend into the kind of reductive or utterly contingent account of the Roman experience that eliminates human agency from the story. Instead Harper furnishes a richly detailed account of the environment in which鈥攁nd with which鈥擱omans and their enemies contended."鈥擶. Jeffrey Tatum, Quarterly Review of Biology
"I recommend The Fate of Rome: Climate, Disease, and the End of an Empire by Kyle Harper. Given all of the other threats we face we thankfully don鈥檛 have to deal with the added dual challenges of climate change or new pandemics鈥攔ight?"鈥擶illiam F. Wechsler, Atlantic Council
"The Fate of Rome is the book every scholar wants to write once during his or her career. . . . In the end, The Fate of Rome is nothing short of monumental. . . . An important work need not be an excellent one鈥攖his is both."鈥擟arson Bay, H-Net Reviews
"This is the story of a great civilization's long struggle with invisible enemies. In the empire's heyday, in 160 CE, splendid cities, linked by famous roads and bustling harbors, stand waiting for the lethal pathogens of Central Africa and the highlands of Tibet. Yet, under the flickering light of a variable sun, beneath skies alternately veiled in volcanic dust or cruelly rainless, this remarkable agglomeration of human beings held firm. Harper's account of how the inhabitants of the empire and their neighbors adjusted to these disasters is as humane as his account of the risks they faced is chilling. Brilliantly written, at once majestic and compassionate, this is truly great history."鈥擯eter Brown, author of Through the Eye of a Needle: Wealth, the Fall of Rome, and the Making of Christianity in the West, 350鈥�550 AD
"In this riveting history, Kyle Harper shows that disease and environmental conditions were not just instrumental in the final collapse of the Roman Empire but were serious problems for centuries before the fall. Harper's compelling and cautionary tale documents the deadly plagues, fevers, and other pestilences that ravaged the population time and again, resulting in far more deaths than ever caused by enemy forces. One wonders how the empire managed to last as long as it did."鈥擡ric H. Cline, author of 1177 B.C.: The Year Civilization Collapsed
"This brilliant, original, and stimulating book puts nature at the center of a topic of major importance鈥攖he fall of the Roman Empire鈥攆or the first time. Harper's argument is compelling and thoroughly documented, his presentation lively and robust."鈥擯eter Garnsey, coauthor of The Roman Empire: Economy, Society, and Culture
"Kyle Harper's extraordinary new account of the fall of Rome is a gripping and terrifying story of the interaction between human behavior and systems, pathogens and climate change. The Roman Empire was a remarkable connector of people and things鈥攊n towns and cities, through voluntary and enforced migration, and through networks of trade across oceans and continents鈥攂ut this very connectedness fostered infectious diseases that debilitated its population. Though the protagonists of Harper鈥檚 book are nonhuman, their effects on human lives and societies are nonetheless devastating."鈥擡mma Dench, author of Romulus鈥� Asylum: Roman Identities from the Age of Alexander to the Age of Hadrian
"Kyle Harper is a Gibbon for the twenty-first century. In this very important book, he reveals the great lesson that the decline and fall of the Roman Empire can teach our own age: that humanity can manipulate nature, but never defeat it. Sic transit gloria mundi."鈥擨an Morris, author of Why the West Rules鈥攆or Now
"The Fate of Rome is a breakthrough in the study of the Roman world鈥攊ntrepid, innovative, even revolutionary."鈥擶alter Scheidel, The Great Leveler: Violence and the History of Inequality from the Stone Age to the Twenty-First Century
"Kyle Harper鈥檚 The Fate of Rome illuminates with a strong new light the entirety of Roman history, by focusing relentlessly on the ups and downs of the Roman coexistence with the microorganisms that influenced every aspect of their lives in powerful ways, while themselves being conditioned by what the Romans did, and failed to do. Others, including myself, have devoted pages to the impact of the greatest epidemics in our books. We missed what happened in between. Harper does not, and the result is a book that is fascinating as well as instructive."鈥擡dward N. Luttwak, author of The Grand Strategy of the Roman Empire
"Learned, lively, and up-to-date, this is far and away the best account of the ecological and environmental dimensions of the history of the Roman Empire."鈥擩. R. McNeill, author of Something New under the Sun: An Environmental History of the Twentieth-Century World
