How and why did the Silk Road originate?

History of Silk Road. From the second century BC to the end of the fourteenth century AD, a great trade route originated from Chang'an (now Xian) in the east and ended at the Mediterranean in the west, linking China with the Roman Empire.

This ancient route between East and West was established during 206 BC to AD 220 in Han Dynasty of China for the political contact with the many Kingdoms of Central Asia. Since then, the Silk Road has also become the trading routes between China and West.
