Plague, Spice and Silk: What the Trade Routes Actually Traded

The Silk Road was never a single road, nor only about silk. It was a web that carried merchants, monks, nomads, and pathogens between empires and across deserts for more than a millennium. Along its routes, history's most valuable commodities—spices, textiles, metals, and beliefs—moved together with something far less desired: disease. This book uncovers what the Silk Road truly traded, blending archaeology, economic history, and bioarchaeology to reveal a system of exchange far richer and more complex than the romantic label suggests. Through caravan accounts, shipwreck cargos, and genetic evidence, it traces how black pepper reached Rome, how Buddhist sutras traveled to China, and how the plague crossed from steppe rodents to Mediterranean ports. By following the movement of both wealth and contagion, the narrative exposes the Silk Road as the first global network—one that connected ecosystems as well as economies, and whose echoes still shape trade and health in our modern world.
