Explanation:

The Mongols made it easier for the propagation of the Black Death from Central Asia to the west and east thanks to the creation of the Silk Road. The disease reached Europe for the first time during 1347 in the Crimea, precisely the city of Caffa. After sorrounding the city for a long time, the Mongol army catapulted their infected dead bodies towards the city in order to infect its people. This eventually led to a wider spreading of the plague, since Genoese traders escaped by ship to Silicy and Southern Europe.

the great wall of china worked as a defense for the feudal states of the zhou dynasty to the north. during the warring states period more walls were put up to defend the borders of the different kingdoms. it was semi successful because despite the wall, the mongols eventually conquered china also the great wall provided protection to the economic development and cultural progress, safeguarded the trading routes such as the silk road, and secured transmission of information and transportation. @jayxboof
