When we think of conquest and empire-building, images of armies and weapons often come to mind. Yet, as Jared Diamond’s Guns, Germs, and Steel reveals, the most devastating agents of conquest were often invisible: germs.
Many deadly diseases that ravaged human populations originated from germs infecting domesticated animals. Smallpox, measles, and influenza evolved in the crowded conditions of farming villages and cities, thriving alongside humans and their livestock. Populations without such animals, such as many Native American and Australian Aboriginal groups, lacked immunity and suffered catastrophic epidemics upon contact with Europeans. These diseases killed more people than weapons, fundamentally altering the course of history.
Simultaneously, advances in metallurgy produced steel weapons and armor far superior to stone or bronze. The invention of guns further revolutionized warfare, providing a decisive edge to societies that developed them. Horses, domesticated thousands of years earlier, offered mobility and shock power on the battlefield.
Writing systems emerged as essential tools for organizing complex bureaucracies, managing resources, and coordinating military campaigns. This administrative capacity allowed states to maintain large armies and project power over vast territories.
Together, germs, guns, and steel formed a deadly synergy that enabled some societies to conquer others with remarkable efficiency. This understanding challenges simplistic narratives of superiority and highlights the complex interplay of biology, technology, and social organization in shaping human history.
