2. The Mongol expansion was one of the expansions that affected the world the most. They started by taking over China, but reached all the way to Hungary. Through the use of trade they helped connect Eurasia with West Africa and other parts of Europe and Asia. The Mongols also had doctors add 36 volumes of Muslim medicine which gave people a better chance of getting through sicknesses that they couldn’t without the medicine.
3. The Mongols had more luck in building an empire than other nomadic groups because they had a lot of military might. They were faster and better armed than sedentary groups. The sedentary peoples didn't have the protection from the Mongols that they needed to keep them at bay. They also had a large group of people in their force, much larger than the other nomadic groups. They were able to use both their strength and their more advanced weaponry to conquer the vast amount of land they did.
4. The Mongol empire fell for two main reasons. The first was that the Mongol leaders started to become more relaxed and grow to like luxury items. Also instead of their old traditions of sleeping on the floor in tents they started living in luxury houses with luxury furniture . The final blow to the Mongol Empire was the outbreak of the Bubonic Plague that killed many of the nomadic people.
