Name

The Silk Road derives its name from the lucrative trade in silk, first developed in China, and a major reason for the connection of trade routes into an extensive transcontinental network. It derives from the German term Seidenstraße (literally "Silk Road") and was first popularized in 1877 by Ferdinand von Richthofen, who made seven expeditions to China from 1868 to 1872. However, the term itself had been in use in decades prior to that. The alternative translation "Silk Route" is also used occasionally. 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.

The 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. William Dalrymple concurs and refers to the India-Rome route as the " Golden Road ".

The southern stretches of the Silk Road, from Khotan (Xinjiang) to Eastern China, were first used for jade and not silk, as long as 5000 BCE, and are 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.
