The medieval warfare was about the Crusades, and during the Crusades, the Western people interacted with the Eastern people, and because of this, they socially and economically influenced each other. The new technologies, science, foods, goods, and other norms began to enter the Western World from the Eastern World. Because of this, the Papacy began to lose its power over the tyrants that it was monarchic governments. “Monarchs gradually won the struggle with the greater feudal lords.” The royal power became superior to the Papacy.
