a return to conditions as they were prior to the war.
1. The Mongols managed to stabilize Asia in the territory they controlled with both military force, and with ethnic, religious, and cultural tolerance.
2. The Mongols contributed to much increased trade between the Europeans and Asians through the Silk Road, especially after they made it safe for travel and trade. This made the people of the two continents much closer, and much more familiar with each other, and it set the stage for the future trade.
3. Before the Mongol conquest, the Europeans saw the Asian people as savages, but after they were able to visit the Far East, and see its development and advancement, they gradually changed their minds, and in many ways felt inferior afterwards.
4. The Mongols had a well established system for fast communication throughout all of their empire, and it was based on horse power and speed, but it was also very well calculated as to how much a single horse can withstand a high speed gallop, so they had stations for changing the horse.
5. Even though the Mongols by many are seen as savages, they were in fact very tolerant to the people's beliefs, and they encouraged all religions in their Empire, and integration between the people with different religious backgrounds.
