Explanation:
The Silk Road consisted of a succession of trails followed by caravans through Central Asia, about 6,400 km in length. Merchants with their caravans were shipping goods back and forth from one trade center to the other.
In addition to silk, major commodities traded included gold, jade, tea, and spices.
The Silk Road was important because it helped to generate trade and commerce between a number of different kingdoms and empires.
I can't really answer your question (as I don't really know enough about 18th century France), but I just want to clear up an (understandable) misconception about Feudalism in your question.
The French revolution was adamant and explicit in its abolition of 'feudalism'. However, the 'feudalism' it was talking about had nothing at all to do with medieval 'feudalism' (which, of course, never existed). What the revolutionaries had in mind, in my own understanding of it, was the legally privileged position of the aristocracy/2nd estate. This type of 'feudalism' was a creation of early modern lawyers and, as a result, is better seen as a product of the early-modern monarchical nation-state, than as a precursor to it. It has nothing to do with the pre-nation-state medieval period, or with the Crusades.
Eighteenth-century buffs, feel free to chip in if I've misrepresented anything, as this is mostly coming from my readings about the historiographical development of feudalism, not any revolutionary France expertise, so I may well have misinterpreted things.
