  • How Did Religion Spread Along the Silk Road? Crash Course Geography #31

    Today we’re going to talk about the collection of routes known as the Silk Roads, and explore how worldview and other ideas spread along those trade routes. The Silk Roads are responsible for everything from the spices we use when we cook to the cloth we see as beautiful, but today we’re going to focus on religion, and show how these routes influenced the beliefs of billions of people through time and space.
