The Silk Road was an ancient network of trade routes that connected the East and West. It was central to cultural interaction between the regions for many centuries.[ The Silk Road primarily refers to the terrestrial routes connecting East Asia and Southeast Asia with East AfricaWest Asia and Southern Europe.

The Silk Road derives its name from the lucrative trade in silk carried out along its length, beginning in the Han dynasty (207 BCE–220 CE). The Han dynasty expanded the Central Asian section of the trade routes around 114 BCE through the missions and explorations of the Chinese imperial envoy Zhang Qian. The Chinese took great interest in the safety of their trade products and extended the Great Wall of China to ensure the protection of the trade route.[

Trade on the Road played a significant role in the development of the civilizations of ChinaKorea, Japan, the Indian subcontinentIran/Persia, Europe, the Horn of Africa and Arabia, opening long-distance political and economic relations between the civilizations.Though silk was the major trade item exported from China, many other goods were traded, as well as religions, syncretic philosophies, sciences, and technologies. Diseases, most notably plague, also spread along the Silk Road.In addition to economic trade, the Silk Road was a route for cultural trade among the civilizations along its network.[

In June 2014, UNESCO designated the Chang’an-Tianshan corridor of the Silk Road as a World Heritage Site. The Indian portion is on the tentative site list.

The Silk Road derives its name from the lucrative Asian silk, a major reason for the connection of trade routes into an extensive transcontinental network. The German terms Seidenstraße and Seidenstraßen (“the Silk Road(s) were coined by Ferdinand von Richthofen, who made seven expeditions to China from 1868 to 1872. The term Silk Route is also used. Although the term was coined in the 19th century, it did not gain widespread acceptance in academia or popularity among the public until the 20th century. The first book entitled The Silk Road was by Swedish geographer Sven Hedin in 1938.

Use of the term ‘Silk Road’ is not without its detractors. For instance, Warwick Ball contends that the maritime spice trade with India and Arabia was far more consequential for the economy of the Roman Empire than the silk trade with China, which at sea was conducted mostly through India and on land was handled by numerous intermediaries such as the Sogdians. Going as far as to call the whole thing a “myth” of modern academia, Ball argues that there was no coherent overland trade system and no free movement of goods from East Asia to the West until the period of the Mongol Empire. He notes that traditional authors discussing East-West trade such as Marco Polo and Edward Gibbon never labelled any route a “silk” one in particular.

The southern stretches of the Silk Road, from Khotan to China, were first used for jade and not silk, as long as 5000 BCE, and is still in use for this purpose. The term “Jade Road” would have been more appropriate than “Silk Road” had it not been for the far larger and geographically wider nature of the silk trade; the term is in current use in China.

Central Eurasia has been known from ancient times for its horse riding and horse breeding communities, and the overland Steppe Route across the northern steppes of Central Eurasia was in use long before that of the Silk Road. Archeological sites such as the Berel burial ground in Kazakhstan, confirmed that the nomadic Arimaspians were not only breeding horses for trade but also great craftsmen able to propagate exquisite art pieces along the Silk Road.[ From the 2nd millennium BCE, nephrite jade was being traded from mines in the region of Yarkand and Khotan to China. Significantly, these mines were not very far from the lapis lazuli and spinel (“Balas Ruby”) mines in Badakhshan, and, although separated by the formidable Pamir Mountains, routes across them were apparently in use from very early times.

Some remnants of what was probably Chinese silk dating from 1070 BCE have been found in Ancient Egypt. The Great Oasis cities of Central Asia played a crucial role in the effective functioning of the Silk Road trade. The originating source seems sufficiently reliable, but silk degrades very rapidly, so it cannot be verified whether it was cultivated silk (which almost certainly came from China) or a type of wild silk, which might have come from the Mediterranean or Middle East.[

Following contacts between Metropolitan China and nomadic western border territories in the 8th century BCE, gold was introduced from Central Asia, and Chinese jade carvers began to make imitation designs of the steppes, adopting the Scythian-style animal art of the steppes (depictions of animals locked in combat). This style is particularly reflected in the rectangular belt plaques made of gold and bronze, with other versions in jade and steatite.] An elite burial near Stuttgart, Germany, dated to the 6th century BCE, was excavated and found to have not only Greek bronzes but also Chinese silks. Similar animal-shaped pieces of art and wrestler motifs on belts have been found in Scythian grave sites stretching from the Black Searegion all the way to Warring States era archaeological sites in Inner Mongolia (at Aluchaideng) and Shaanxi (at Keshengzhuang) in China.

The expansion of Scythian cultures, stretching from the Hungarian plain and the Carpathian Mountains to the Chinese KansuCorridor, and linking the Middle East with Northern India and the Punjab, undoubtedly played an important role in the development of the Silk Road. Scythians accompanied the Assyrian Esarhaddon on his invasion of Egypt, and their distinctive triangular arrowheads have been found as far south as Aswan. These nomadic peoples were dependent upon neighbouring settled populations for a number of important technologies, and in addition to raiding vulnerable settlements for these commodities, they also encouraged long-distance merchants as a source of income through the enforced payment of tariffs. Sogdians played a major role in facilitating trade between China and Central Asia along the Silk Roads as late as the 10th century, their language serving as a lingua franca for Asian trade as far back as the 4th century.

New Silk Road

After an earthquake that hit Tashkent in Central Asia in 1966, the city had to rebuild itself. Although it took a huge toll on their markets, this commenced a revival of modern silk road cities.[

The Eurasian Land Bridge (a railway through China, Kazakhstan, Mongolia and Russia) is sometimes referred to as the “New Silk Road”. The last link in one of these two railway routes was completed in 1990, when the railway systems of China and Kazakhstan connected at Alataw Pass (Alashan Kou). In 2008 the line was used to connect the cities of Ürümqi in China’s Xinjiang Province to Almatyand Astana in Kazakhstan. In October 2008 the first Trans-Eurasia Logistics train reached Hamburg from Xiangtan. Starting in July 2011 the line has been used by a freight service that connects Chongqing, China with Duisburg, Germany, cutting travel time for cargo from about 36 days by container ship to just 13 days by freight train. In 2013, Hewlett-Packard began moving large freight trains of laptop computers and monitors along this rail route. In January 2017, the service sent its first train to London. The network additionally connects to Madrid and Milan.
