In the early crusades men of all ranks from all over Europe took the cross and went to fight Islam. Some went out of religious fervour, others to escape the plague and famine, still others in search of land or fortune. Fighting alongside them were the armies raised in Outremer, the Holy Land itself. Together they waged a bloody religious war, the participants of which included such forces as the Knights Templar, the Teutonic Knights and the Byzantine Army.
