This is part 4 of our series on the Crusades.The plan for this episode, the last in our look at the Crusades, is to give a brief review of the 5th thru 7th Crusades, then a bit of analysis of the Crusades as a whole.The date set for the start of the 5th Crusade was June 1st, 1217. It was Pope Innocent III’s long dream to reconquer Jerusalem. He died before the Crusade set off, but his successor Honorius III was just as ardent a supporter. He continued the work begun by Innocent.The Armies sent out accomplished much of nothing, except to waste lives. Someone came up with the brilliant idea that the key to conquering Palestine was to secure a base in Egypt first. That had been the plan for the 4th Crusade. The Crusaders now made the major port of Damietta their goal. After a long battle, the Crusaders took the city, for which the Muslim leader Malik al Kameel offered to trade Jerusalem and all Christian prisoners he held. The Crusaders thought the Holy Roman Emperor Frederick II was on his way to bolster their numbers, so they rejected the offer. Problem is, Frederick wasn’t on his way. So in 1221, Damietta reverted to Muslim control.Frederick II cared little about the Crusade. After several false starts that revealed his true attitude toward the whole thing, the Emperor decided he’d better make good on his many promises and set out with 40 galleys and only 600 knights. They arrived in Acre in early Sept. 1228. Because the Muslim leaders of the Middle East were once again at odds with each other, Frederick convinced the afore-mentioned al-Kameel to make a decade long treaty that turned Jerusalem over to the Crusaders, along with Bethlehem, Nazareth, and the pilgrim route from Acre to Jerusalem. On March 19, 1229, Frederick crowned himself by his own hand in the Church of the Holy Sepulcher.This bloodless assumption of Jerusalem infuriated Pope Gregory IX who considered control of the Holy Land and the destruction of the Muslims as one and the same thing. So the Church never officially acknowledged Frederick’s accomplishments.He returned home to deal with internal challenges to his rule and over the next decade and a half, the condition of Palestine’s Christians deteriorated. Everything gained by the treaty was turned back to Muslim hegemony in the Fall of 1244.The last 2 Crusades, the 6th and 7th, center on the career of the last great Crusader; the king of France, Louis IX.Known as SAINT Louis, he combined the piety of a monk with the chivalry of a knight, and stands in the front rank of all-time Christian rulers.  His zeal revealed itself not only in his devotion to religious ritual, but in his refusal to deviate from his faith even under the threat of torture. His piety was genuine as evidenced by his concern for the poor and the just treatment of his subjects. He washed the feet of beggars and when a monk warned him against carrying his humility too far, he replied, “If I spent twice as much time in gambling and hunting as in such services, no one would find fault with me.”The sack of Jerusalem by the Muslims in 1244 was followed by the fall of the Crusader bases in Gaza and Ashkelon. In 1245 at the Council of Lyons the Pope called for a new expedition to once again liberate the Holy Land. Though King Louis lay in a sickbed with an illness so grave his attendants put a cloth over his face, thinking he was dead, he rallied and took up the Crusader cross.Three years later he and his French brother-princes set out with 32,000 troops. A Venetian and Genoese fleet carried them to Cyprus, where large-scale preparations had been made for their supply. They then sailed to Egypt. Damietta once again fell, but after this promising start, the campaign turned into a disaster.Louis’ piety and benevolence was not backed up by what we might call solid skills as a leader. He was ready to share suffering with his troops but didn’t possess the ability to organize them.  Heeding the counsel of sever
