About this book

Humans did not make history – we played host.

According to the accepted narrative of progress, a few great humans have bent the arc of history. But in this revelatory book, Dr Jonathan Kennedy argues that germs have done more to shape humanity at every stage, from the first success of Homo sapiens over the equally intelligent Neanderthals to the fall of Rome and the rise of Islam.

How did an Indonesian volcano help cause the Black Death, setting Europe on the road to capitalism? How could 168 men extract the largest ransom in history from an opposing army of eighty thousand? And why did the Industrial Revolution lead to the birth of the modern welfare state?

The latest science reveals that infectious diseases are not just something that happens to us, but a fundamental part of who we are. Indeed, the only reason humans don't lay eggs is that a virus long ago inserted itself into our DNA, and there are as many bacteria in your body as there are human cells. We have been thinking about the survival of the fittest all wrong: evolution is not simply about human strength and intelligence, but about how we live and thrive in a world dominated by microbes.

By exploring the startling intimacy of our relationship with infectious diseases, Kennedy shows how they have been responsible for some of the seismic revolutions of the past 50,000 years. Provocative and brimming with insight, Pathogenesis transforms our understanding of the human story, revealing how the crisis of a pandemic can offer vital opportunities for change.

Media reviews

– A BBC Radio 4 book of the week
– A Times science book of the year
– A Sunday Times science book of the year

"This sweeping history is Kennedy's debut, and a powerfully argued one [...] Pathogenesis sets out, like Yuval Noah Harari's Sapiens or Peter Frankopan's recent The Earth Transformed, to reinterpret the entire history of mankind [...] A fascinating and pacey run through the history of humanity from an unfamiliar perspective."
– Book of the Week, Sunday Times

"This book challenges some of the greatest cliches about colonialism and leaves you wondering why you ever gave them the time of day. A revelation, and also that rarest thing, a science title that is entirely comprehensible and often a pleasure to read."
– Sathnam Sanghera, bestselling author of Empireland

"Pathogenesis is superbly written. Kennedy seamlessly weaves together scientific and historical research, and his confident authorial voice is sure to please readers of Yuval Noah Harari or Rutger Bregman."
– David Robson, The Times

"Thrilling and eye-opening. From neolithic diseases to COVID-19, Jonathan Kennedy explores the enormous role played by some of the tiniest life on Earth: the power of plagues in shaping world history."
– Professor Lewis Dartnell, bestselling author of Origins and Being Human

"From the fall of Rome to the Spanish conquest of the Americas to the industrial revolution, germs have played as much a role in history as guns, generals and "great men" [...] Jonathan Kennedy restores the microbes of infectious disease to their rightful place in the story of human evolution and the rise and fall of civilisations. Science and history at its best."
– Dr Mark Honigsbaum, author of The Pandemic Century

"Kennedy's book, which aims to show how infectious disease has shaped us from the time of the Neanderthals to the era of COVID-19, is full of amazing facts [...] Pathogenesis doesn't only cover thousands of years of history – it seeks radically to alter the way the reader views many of the (often very well-known) events it describes."
– Rachel Cooke, Observer

"Professor Kennedy – drawing on the latest research in fields ranging from genetics and anthropology to archaeology and economics – explores eight major outbreaks of infectious disease across the entire history of civilization [...] It's not often you pick up a book that promises to alter your entire understanding of the story of humanity."

"An absorbing book [...] Kennedy's intertwined story of humanity and humongous disease is told lucidly and knowledgeably, with ample historical context."

"How a virus might have written human history. This is a fascinating, readable, and superbly researched account of how infectious diseases have shaped our history, from the Palaeolithic Era to COVID."
– Professor David Christian, bestselling author of Origin Story and Future Stories

"Our very existence and success as a species, Kennedy argues in this fascinating book, has been shaped by bacteria and viruses."
– Book of the Day, Guardian

"I love this surprising, learned, fascinating book which brings human arrogance into sharp relief, reminding us that the real masters of the universe are microbes. Jonathan Kennedy travels through history, unpicking everything we thought we knew; we are but the pawns and playthings of viruses and bacteria. Mind-blowing."
– Cal Flyn, bestselling author of Islands of Abandonment

"Well-timed [...] compelling [...] hopeful [...] Yes, our trajectory is defined by microbes. But it's also influenced by our reactions to them – and our acknowledgment of their power."
The Atlantic

"A compelling account of the role of bacteria and viruses in world history. Dr Kennedy marshals a dizzying range of material, from the transition from feudalism to capitalism in Europe to the rise of the slave trade to the defeat of the British army by American revolutionaries in Yorktown in 1781 [...] an entertaining read."

"New and timely [...] His book is full of surprises [...] At this moment of reckoning over humankind's planetary footprint, Pathogenesis offers a humbling reminder that history is made not by the great and the good, but those who survive."
New Scientist

"What has shaped the world? Not gods, not heroes, not even conquistadors, but germs [...] fascinating [...] We must collaborate [...] It's up to us."
New Statesman

"Jonathan Kennedy's excellent book details how germs have been laying waste to varied civilisations since Homo sapiens became dominant some 50,000 years ago [...] Kennedy has a fluent and engaging style. He showcases his interdisciplinary training over 300 pages that take in vast swathes of history."
The Critic

"Kennedy is right to state that pandemics and plague outbreaks have had a big influence throughout human history. Such dramatic episodes get written up by historians, and Kennedy describes their accounts with verve."

"Gripping [...] [Kennedy] wrangles an astonishing breadth of material into easily accessible, plain prose [...] Even readers familiar with the material will find [Pathogenesis] fascinating [...] Kennedy will leave readers galvanized by the time they flip to the last page, having assured us that we could win the narrative back from germs – if we're able to muster the political will to do so."
Washington Post

"it's refreshing to see a first-time writer take aim at what he sees as the failings of two of the best-read popular history titles of the past 30 years [...] The book shines when it brings cutting-edge science to bear [...] something that Kennedy treats with great care [...] germs feel powerfully alive and at work in history [...] Pathogenesis shows a microbial world that is as complex, dynamic, and alive as the human one, and just as consequential."
Financial Times

"Three hundred-odd pages roam through 50,000 years, and by the last it's almost impossible to disagree that infectious diseases are our permanent companion and ultimate adversary [...] The fluency of Kennedy's narration is remarkable, weaving Tolkien, Game of Thrones and Monty Python into memorable and accessible explanations of genetics, evolutionary biology and demography [...] Pathogenesis is a humbling story for humankind."
– Kate Womersley, Spectator

"Kennedy debuts with a virtuoso analysis of the fallout from encounters between deadly viral and bacterial pathogens and human populations that lacked immunity [...] He marshals a wealth of surprising scholarship in lucid and succinct prose. The result is a fascinating look at history from the perspective of its tiniest protagonists."
Publishers Weekly, starred review

"After recent years you don't need us to tell you that infectious diseases have the power to change history [...] A compelling case"
– All the best books to look forward to in 2023, GQ
