Effects on Feudalism
The crusades couldn't be unsuccesful to affect a bunch of ways the life of western Europe. For example, they helped to weaken feudalism. Many Barons and knights sold their land in order to get money for a crusading expedition. Many more died in Syria and their residence, through failure of succesors, changed to the crown. Moreover, private warfare, which was popular during the Middle Ages, also tended to die out with the departure for the Holy Land of so many turbulent feudal lords. Their decline in both numbers and influence, and the correspondin harmonizing growth of the royal authority, may best be traced in the changes that came about in France, the original home of the crusading movement.
