This trade route was crucial not only for the exchange of goods like silk and spices but also for the dissemination of ideas, technologies, and cultural practices across vast regions.

As these empires fell, the stability that facilitated long-distance trade was severely undermined. Regional conflicts, invasions, and the general fragmentation of governance made it more challenging for merchants to travel safely and for trade to thrive.
