Silk and New Crops
Archaeology and linguistic studies show that the peoples of Central Asia engaged in longdistance movement and exchange from at least 1500 B. c.E. In Roman times Europeans became captivated by the idea of a trade route linking the lands of the Mediterranean with China by way of Mesopotamia, Iran, and Central Asia. The Silk Road, as it came to be called in modern times, experienced several periods of heavy use (see Map 8.1). The first began around 100 b. c.e.
Origins and Operations
The Seleucid kings who succeeded to the eastern parts of Alexander the Great's empire in the third century B. c.E. focused their energies on Mesopotamia and Syria. This allowed an Iranian nomadic leader to establish an independent kingdom in northeastern Iran. The Parthians, a people originally from east of the Caspian Sea, had become a major force by 247 B. c.E. They left few written sources, and recurring wars with Greeks and Romans to the west prevented travelers from the Mediterranean region from gaining firm knowledge of their kingdom. It seems likely, however, that they helped foster the Silk Road by being located on the threshold of Central Asia and sharing customs with steppe nomads farther to the east.
In 128 B. c.E. a Chinese general named Zhang Jian (jahng jee-en) made his first exploratory journey across the deserts and mountains of Inner Asia on behalf of Emperor Wu of the Han dynasty. After crossing the broad and desolate Tarim Basin north of Tibet, he reached the fertile valley of Ferghana (fer-GAH-nuh) and for the first time encountered westward-flowing rivers. There he found horse breeders whose animals far outclassed any horses he had seen. Later Chinese historians looked on General Zhang, who ultimately led eighteen expeditions, as the originator of overland trade with the western lands, and they credited him with personally introducing a whole garden of new plants and trees to China.
Long-distance travel suited the people of the steppes more than the Chinese. The populations of Ferghana and neighboring regions included many nomads who followed their herds. Their migrations had little to do with trade, but they provided pack animals and controlled transit across their lands. The trading demands that brought the Silk Road into being were Chinese eagerness for western products, especially horses, and on the western end, the organized Parthian state, which had captured the flourishing markets of Mesopotamia from the Seleucids.
By 100 B. c.E., Greeks could buy Chinese silk from Parthian traders in Mesopotamian border entrepots. Yet caravans also bought and sold goods along the way in prosperous Central Asian cities like Samarkand and Bukhara. These cities grew and flourished, often under the rule of local princes.
General Zhang definitely seems to have brought two plants to China: alfalfa and wine grapes. The former provided the best fodder for horses. In addition, Chinese farmers adopted pistachios, walnuts, pomegranates, sesame, coriander, spinach, and other new crops. Chinese artisans and physicians made good use of other trade products, such as jasmine oil, oak galls (used in tanning animal hides, dyeing, and making ink), sal ammoniac (for medicines), copper oxides, zinc, and precious stones.
