Answer:
The Crusades were a series of religious wars between Christians and Muslims started primarily to secure control of holy sites considered sacred by both groups. In all, eight major Crusade expeditions occurred between 1096 and 1291. The bloody, violent and often ruthless conflicts propelled the status of European Christians, making them major players in the fight for land in the Middle East.
What Were the Crusades?
In November 1095, at the Council of Clermont in southern France, the Pope called on Western Christians to take up arms to aid the Byzantines and recapture the Holy Land from Muslim control. This marked the beginning of the Crusades.
Pope Urban’s plea was met with a tremendous response, both among the military elite as well as ordinary citizens. Those who joined the armed pilgrimage wore a cross as a symbol of the Church.
The Crusades set the stage for several religious knightly military orders, including the Knights Templar, the Teutonic Knights, and the Hospitallers. These groups defended the Holy Land and protected pilgrims traveling to and from the region.
