Some of the benefits a of the crusades can be a positive but mostly negative. Document five states that they were many battles between the colonies and some traded along the ways of the movement between the countries. This is relevant because even though there were some of the positive impacts,they were still other things that made it incomparable between them. Document seven,it states that the crusades were hard to maintain and often abused christians and jews.They were hard to maintain because the amount of soldiers and the food were low and had to raise prices while trading with trading groups. This is relevant because this shows the hard things they went through but still cost the lives lost in the long battles.
