Could anybody please list four major effects of the crusades.?
Effects of the Crusades on Commerce They created a constant demand for the transportation of men and supplies, encouraged ship-building, and extended the market for eastern wares in Europe. Effects of the Crusades on Feudalism They helped to undermine feudalism. Thousands of barons and knights mortgaged or sold their lands in order to raise money for a crusading expedition. Thousands more perished in Syria and their estates, through failure of heirs, reverted to the crown. Moreover, private warfare, which was rife 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 corresponding growth of the royal authority, may best be traced in the changes that came about in France, the original home of the crusading movement. Political Effects of the Crusades They helped to break down the power of the feudal aristocracy, and to give prominence to the kings and the people.
