In the late Middle Ages, the Crusades occurred, lasting for about 200 years (c. 1090–1290 AD). The Crusaders were generally men of religious and military orders: priests, brothers, and knights. Their mission was to reclaim the Holy Land for the Christian faithful. As they traveled throughout Europe and the Near East, they gathered new information, learned new ways of doing things, and obtained different products and goods. The Crusaders were interested in the organized facilities for the sick that the Moslems used. As a result, similar hospitals were built near battlefields; the men were sometimes assigned to fighting and sometimes to caring for the sick and the injured. Eventually, military nursing orders evolved.
