Answer:
Modernizing the technology of Europe
Step-by-step explanation:
The crusades were military expeditions organized between 1095 and 1291 by the European Christian powers, with the stated aim of combating Islamic rule in the so-called Holy Land, regaining Jerusalem and other places where Jesus would have lived.
The endeavor was a mixture of war, pilgrimage, and penance: the Crusader warriors, also known as “penitent pilgrims,” believed that their sins would be forgiven if they completed the journey and fulfilled the divine mission of freeing holy places, such as the Church of the Holy Sepulcher. The purpose of the crusades was to stop the spread of Islam in Europe, to conquer lands on the way to the Holy Land, and to rebuild religious shrines in the Holy Land.
