The Silk Road: The Ancient Internet That Connected East and West

A Misleading Name

“Silk Road” was coined in 1877 by German geographer Ferdinand von Richthofen. The name is misleading in two ways.

First, it was never a single road — it was a vast network of overland and sea routes crisscrossing Central Asia, the Middle East, and the Indian Ocean. Second, silk was just one of many commodities. Spices, glass, ceramics, horses, gold, and — far more consequentially — ideas, religions, diseases, and technologies all traveled these routes.

Two Thousand Years of Exchange

The Silk Road became fully active during the Han Dynasty (206 BCE–220 CE). Emperor Wu dispatched envoy Zhang Qian westward to forge alliances against the nomadic Xiongnu. Though the military mission largely failed, Zhang Qian opened diplomatic and commercial contacts with Central Asian kingdoms, Persia, and eventually the Roman world.

East to West: silk, porcelain, paper, gunpowder, compass West to East: glassware, wine, cotton, Buddhism, Islam, Christianity

Rome and China: In the 1st century BCE, Chinese silk reached Rome through Persian intermediaries. Roman aristocrats were obsessed with Chinese silk. Yet the two empires had only the haziest awareness of each other. Rome called China “Serica” — the silk land — a mythical place at the edge of the world.

The Highway of Religions

Perhaps the most significant things the Silk Road transported were religions.

Buddhism: Spreading from India through Central Asia into China in the 1st century CE, then onward to Korea and Japan. East Asian Buddhist civilization would not exist without the Silk Road.

Islam: After the 7th-century Arab expansion, Islam spread eastward through Central Asia along the same routes, eventually reaching China and Southeast Asia.

Christianity: Nestorian Christians traveled the Silk Road east, establishing churches in Central Asia and China. By 635 CE, there was already a Christian church in Tang Dynasty China.

Pax Mongolica: The Golden Age

Paradoxically, the Silk Road’s greatest era came under conquest. When the Mongol Empire unified Eurasia in the 13th century, merchants could travel from China to the Black Sea in safety.

Marco Polo’s famous journey across Asia was possible precisely because of this Mongol peace. His book, The Travels of Marco Polo, gave Europeans their first detailed account of China.

The Dark Side: Plague

The Silk Road didn’t only carry good things. In the 14th century, the Black Death traveled westward along Silk Road networks from Central Asia. Mongol armies besieging a Crimean trading city reportedly catapulted plague-infected corpses over the walls — spreading the disease to Mediterranean trading ships and, from there, to all of Europe.

One-third of Europe’s population died.

The Modern Silk Road

China’s Belt and Road Initiative (BRI), launched in 2013, is the 21st-century Silk Road — a massive infrastructure project connecting Asia, Africa, and Europe via land corridors and sea lanes, now involving over 140 countries.

Where ancient caravans moved silk on camels, modern freight trains run from China to Europe in 12 days. History rhymes.
