The First Crusade was the only fully successful one and had five main contingents under Count Raymond of Toulouse, Geoffrey of Bouillon, Bohemon of Taranot, Count Robert of Flanders, and Duke Robert of Normandy. Byzantine emperor Alexius promised they would hold as Byzantine fiefs whatever lands they conquered from the Muslims, Alexius resupplied them and sent them on their way. After two long and hard years of campaigning in Anatolia and Syria, the crusader reached the Holy Land and in July 1099 took Jerusalem. Once entering the city a bloodbath ensued as they slaughtered civilians and setting fire to shops, homes, mosques, and synagogues. The bloody scene was not a odd occurrence as religious zeal ran extraordinarily high among Europeans.
