In order to become rich, powerful, and prestigious in the pre-modern world, nothing mattered more than horses. They were the fundamental unit of warfare, enabling cavalry charges, and logistical support. They facilitated the creation of the Silk Road (which could arguably be called the “Horse Road”) since China largely built it to enable the purchase of millions of horses to fight its nomadic neighbors to the north. The term "caballero," meaning a gentleman or knight in Spanish, derived from the Latin "caballus" (horse), reflecting how wealth, status, and the skilled ability to ride a horse defined chivalric ideals in medieval society.
From the windswept Eurasian steppe to the royal stables of Persia and the warpaths of Genghis Khan, today’s guest, David Chaffetz, author of Raiders, Rulers, and Traders traces the story of how horses changed the world—not just in warfare, but in statecraft, commerce, and culture. Chaffetz makes the case that the so-called “Silk Road” might more accurately be remembered as the Horse Road.
Horse-driven mobility shaped empires from Assyria and the Achaemenids to the Mughals and the Soviets. Just as we rely on the Internet today, ancient societies depended on the horse as a transformative technology that shaped everything from warfare to governance.
