What was the Silk Road? Trade routes, cities and ideas explained

The short answer

The Silk Road was not a single road but a network of trade routes across Asia that connected China with Central Asia, India, Persia and the lands around the Mediterranean. Caravans of camels crossed deserts and mountain passes, ships sailed along the coasts, and goods, people and ideas moved between very different societies. The name was invented in the 19th century by the German geographer Ferdinand von Richthofen. People in ancient times did not call it that.

How it began

Trade across parts of Asia existed long before it had a famous name. Jade, for example, was traded from the Tarim Basin to China for centuries. The Han dynasty in China gave the network a big push in the second century BCE. The envoy Zhang Qian travelled west to look for allies and returned with knowledge about the peoples of Central Asia. Soon after, China sent missions and organised trade with the west and imported fine horses from Central Asia.

Routes and oasis cities

The huge Taklamakan Desert in western China forced caravans to choose between a northern and a southern route around it. Oasis towns in the Tarim Basin, such as Kashgar, gave travellers water, food, rest and markets. Cities in Central Asia like Samarkand grew rich as crossroads. In the west the routes reached the Mediterranean and in the south they met sea routes leading to India. At sea, sailors used monsoon winds to cross the Indian Ocean on the Maritime Silk Road.

Goods and middlemen

• From China: silk, but also porcelain, tea and later paper.
• From the west: gold, silver, glass, wool, wine and fine horses.
• From the south: spices, gems and cotton.

Traders rarely journeyed the whole distance. Goods normally moved in stages, passing through many markets and hands, and prices rose with each step. The Sogdians, merchants from Central Asia with a home region around Samarkand, were especially important middlemen and spread their language across the routes.

Ideas travelled too

Along the roads moved religions, art, technologies and knowledge. Buddhism spread from India through Central Asia to China. Later, Islam spread along the same routes. Techniques such as papermaking moved west. Diseases could travel with the caravans as well, and historians often connect the spread of plague to trade networks.

Decline and revival

Political changes, new sea routes and shifting empires changed the trade over time. In the 15th and 16th centuries European sailors looked for direct sea routes to Asia. Historians still discuss how much the fall of Constantinople in 1453 mattered. Today the name is used again: parts of the historic routes are UNESCO World Heritage sites and modern projects use the “Silk Road” name for new transport links.

Myths about the Silk Road

• “It was one road.” It was a changing web of routes.
• “It carried only silk.” Many goods, and even more ideas, moved along it.
• “Merchants travelled from China to Rome.” Goods travelled that far, but most merchants covered only a part.
