This was The Crusade That Never Happened. Pope Innocent III called for another Crusade to free the Holy Land in 1198. He decided on Venice as the point of departure, a very poor choice indeed. The Venetians diverted the Crusaders from their mission. In 1202, Venetian merchants convinced the Crusaders to attack the Christian city of Zara. They laid seige and eventually captured the city. In 1204, they convinced Crusaders to attack Constantinople. In August, they captured and looted the ancient city, which never quite recovered. None of the Crusaders ever came close to making it to the Holy Land.
