Answer:
The Silk Road was important because it helped to generate trade and commerce between a number of different kingdoms and empires. This helped for ideas, culture, inventions, and unique products to spread across much of the settled world.
by gaining a ton of land and exploiting the people on that land you get resources, right? and those resources are the ability to use that new land's ports, military, resources (goods and services), and culture. I hope this helped!
