The name ' Silk Routes ' points to the importance of Westbound Chinese silk cargoes along this route.

They are known to have existed before the Christian Era and thrived almost till the fifteenth century.

Much before all this, Buddhism emerged from eastern India and spread in several directions through intersecting points on the Silk Routes.
