Why did the expansion of Mongol rule lead to the spread of ideas and technologies? How did the Mongols contribute to this?

The blast furnace improved European metal production, the triangular plow revolutionized agriculture, and gunpowder was responsible for the development of modern warfare. The Mongols used gunpowder to develop hand grenades and were the first nation in history to use them.

Explanation:

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
