Four Inventions That Changed The World
Considering that an economic boom lead to increased trade with Europe and ended with the re-birth of the Silk Road, I predict that the different cultures along the trade route, as a result of the exportation of the four inventions that changed the world( compass, paper, gunpowder, and printing ) will get jealous of the other country(ies) that have the good inventions and start a war with them for their invention. They would want to make their trading easier and quicker so they can save money. So they would fight over their inventions. Some people would team up and share their inventions so there would be less war. That is what I think would have happen to the cultures along the trade route.
