How did the consequences of the Crusades compare to the initial causes

The crusaders of the 11th to 15th century C.E have become one of the defining events of the Middle Ages in both Europe and the Middle East. The campaigns brought significant consequences wherever they occurred but also pushed changes with in the states that organised and fought them. Even when the crusades had ended, their influence continued through literature and other cultural means and, resurrected as an idea in more modern times, they continue today to color international relations.

Many exaggerated claims have been concerning the effects and consequences of the crusades on life in the Middle Ages and later. There were, undoubtedly, momentous changes in the life, politics and religion from the 11th and 14th centuries C.E, but it is perhaps prudent to heed the words of historians and acclaimed Crusades expert T.Asbridge.
