Silk gave the Silk Road its modern name, although many other goods also crossed the routes.
Silk was produced in ancient China and became a highly valued commodity in distant markets. Its light weight, durability, texture, and prestige made it especially suitable for long-distance trade. Silk traveled westward through exchanges involving merchants, states, and intermediary communities rather than through one continuous journey by a single trader.
The name “Silk Road” is modern: the German geographer Ferdinand von Richthofen popularized the term “Seidenstraße” in the 19th century. Historians now use it for a broad network of land and sea connections linking East Asia with Central Asia, the Middle East, Africa, and Europe.
Silk was never the only important product. Horses, spices, glassware, metals, gems, paper, textiles, medicines, and ideas also moved along these networks. Religions, artistic styles, technologies, languages, and diseases traveled with people as well, which is why the Silk Road is better understood as a system of exchanges than as one road.
