Answer:
It led to a money based system of exchange.
Step-by-step explanation:
With the Crusades being at its final stages in order of trying to take Jerusalem over, this led to the political system of Fedualism to lose power. This system involved with people (vassals) getting their own land if they give or promise loyalty to a powerful Noble, or in other words, a Lord. The economy back then was based on agriculture. In addition, there were also serfs who were working on the Manors. If they work, then they get protection and food from the Lord. During the Crusades, the Mongol Empire closed up the Silk Road because it was too dangerous in Europe. With the conflict ending, trade routes opened, and trading increased. Guilds and merchants were gaining more power, trade increased between Europe and Asia, and Fedualism was dying down. As well as the Crusades, the Bubonic Plague and the Hundred Years' War ended Fedualism. The Crusades started to weaken Fedualism.
