Asia: The silk routes are a good example of vibrant pre-modern trade before the 17th century. The historians have identified several silk routes, overland and by sea, linking Asia with Europe and northern Africa. .These routes were used for trades in Chinese pottery, textiles and spices from India and Southeast Asia. In return, precious metals – gold and silver – came from Europe to Asia.’ Secondly, Christian missionaries and later Muslim preachers travelled through these routes. It may be mentioned here that in ancient times, Buddhism too spread in several directions through intersecting points on the silk routes. (b) Americas: After the discovery of the Americas by Christopher Columbus, many of our common foods such as potatoes, soya, groundnuts, maize, tomatoes, chilies came from America’s original inhabitants i.e., the American Indians. From the sixteenth century, America’s vast lands, abundant crops and minerals transformed trade and lives everywhere. Precious metals like silver from mines in Peru and Mexico enhanced Europe’s wealth and financed its trade with Asia. Legends spread in seventeenth-century Europe about South America’s fabled wealth. Many expeditions set off in search of El Dorado, the fabled city of gold. Thus there were global exchanges before the seventeenth century.
