The Silk Road was a network of overland trade routes that crossed Eurasia from about the 2nd century BCE until the mid-15th century CE. It linked China with Central Asia, India, Persia, the Arab world and the Mediterranean. The name comes from Chinese silk, one of the most valuable goods carried westward. The routes also carried many other goods, as well as religions, technologies, languages, artistic styles and diseases. The Silk Road was never one continuous highway. It was a shifting web of caravan tracks, oasis towns and regional markets. Very few people travelled its whole length. Most goods moved in stages, passing from one group of merchants to the next. Sea lanes across the Indian Ocean are often called the Maritime Silk Road, and they formed a parallel and growing part of the same exchange system.
Name
The term is modern. The German geographer Ferdinand von Richthofen popularised Seidenstraße ("Silk Road") in 1877. He used it for the routes that linked Han China with Central Asia and the West. Historians now often prefer the plural "Silk Roads" or "Silk Routes" to make clear that there were many routes. Pre-modern travellers did not use the name. Even Marco Polo, whose name is closely tied to the Silk Road, never used the term.
Origins
Long-distance exchange across the Eurasian steppe and the Iranian plateau started well before the Silk Road had a name. The conquests of Alexander the Great and the Hellenistic kingdoms that followed them carried Greek influence as far as Bactria. On the Chinese side, the usual starting point is the missions of Zhang Qian. Emperor Wu of the Han dynasty sent him west around 139/138 BCE to find allies against the Xiongnu nomadic confederation. The Xiongnu captured Zhang Qian and held him for years. He did not secure an alliance, but he reached Ferghana, Sogdiana and Bactria and returned with detailed reports on the lands to the west. A second mission, to the Wusun, ended in 115 BCE. It led to closer diplomatic and commercial contacts between the Han and the states of the Western Regions.
The Han then pushed into the Hexi Corridor and the Tarim Basin and built garrisons, beacon towers and commanderies such as Dunhuang. Ferghana's prized "heavenly horses" were one of the main motives for this westward push. Chinese silk reached the Roman Empire through Parthian and other intermediaries. In Rome it was a luxury good that moralists criticised.
Routes and geography
The classic eastern terminus was Chang'an (modern Xi'an). From there, routes ran through the Hexi Corridor to Dunhuang. Beyond Dunhuang they split around the Taklamakan Desert:
- a northern route along the foot of the Tian Shan through Turpan and Kucha;
- a southern route along the Kunlun Mountains through Khotan.
The two routes met again at Kashgar. From Kashgar, routes crossed the Pamirs to Samarkand, Bukhara and Merv. They continued across Iran to Mesopotamia and the ports of the Levant and the Black Sea. Branches ran south through the Karakoram passes to northern India, and north across the steppe. Bactrian camels, oasis caravanserais and local guides made the deserts and mountain passes crossable.
Goods and merchants
Goods travelling west included silk, lacquerware, bronze mirrors and, later, porcelain. Goods travelling east included horses, glassware, silver vessels, wool, gems, incense and spices. Plants also moved along the routes: grapes and alfalfa reached China, and many crops spread in both directions.
From roughly the 4th to the 8th century, the Sogdians, an Iranian people based around Samarkand, were the leading middlemen. Their merchant communities stretched from Central Asia into northern China. Persians, Indians, Armenians, Jews, Arabs, Uyghurs and others also took leading roles at different times. In the 6th century, silkworm eggs were reportedly smuggled to the Byzantine Empire. This ended China's monopoly on sericulture, although Chinese silk kept its prestige.
Exchange of ideas and religions
The Silk Road was a major channel for spreading religion. Buddhism travelled from India and Gandhara through Central Asia into China in the first centuries CE. This led to a huge project of translation and to cave temples such as those at Dunhuang. The pilgrim Xuanzang travelled overland to India and back between 629 and 645. Manichaeism, Zoroastrianism and the Church of the East also reached China, the last in 635 under the Tang dynasty. Islam later spread across Central Asia.
Technologies also crossed Eurasia along these routes. One tradition says that Chinese prisoners taken at the Battle of Talas (751) brought papermaking to Samarkand. Papermaking then spread through the Abbasid Caliphate. Knowledge of gunpowder and printing spread west in later centuries. The Dunhuang "Library Cave", found in 1900, held thousands of manuscripts in many languages. Among them was the Diamond Sutra of 868, the oldest dated printed book known.
Later history and decline
Tang control of the Tarim Basin weakened after the An Lushan Rebellion (755–763). After that, overland trade broke up among regional powers, and sea trade grew in importance during the Song dynasty.
In the 13th and 14th centuries, the Mongol Empire united much of Eurasia under one rule. This made long-distance travel safer for a time, and it was the period of Marco Polo's journeys. The same connections probably helped the Black Death spread westward in the 1340s.
When the Mongol successor states broke apart, the overland routes became fragmented again. The Ottoman capture of Constantinople in 1453, the Ming dynasty's restrictive policies and the rise of European sea routes to Asia from the late 15th century all moved long-distance trade toward the oceans.
Legacy and heritage
The Silk Road has become a symbol of cross-cultural exchange. Scholars have studied it in archaeology, philology and global history. In 2014, UNESCO inscribed "Silk Roads: the Routes Network of Chang'an-Tianshan Corridor" as a World Heritage Site. It covers 33 sites across China, Kazakhstan and Kyrgyzstan and was jointly nominated by the three countries. The Zarafshan-Karakum Corridor in Central Asia was added in 2023. The name is also used for modern infrastructure and trade programmes, including China's Belt and Road Initiative.
