"Emperor Frederick II, who was to be the leader of the crusade, had remained in Europe and continued to importune the pope for new postponements of his departure. On 9 November, 1225, he married Isabelle of Brienne, heiress to the Kingdom of Jerusalem, the ceremony taking place at Brindisi. Completely ignoring his father-in-law, he assumed the title of King of Jerusalem. In 1227, however, he had not yet left for Palestine. Gregory IX, elected pope 19 March, 1227, summoned Frederick to fulfil his vow. Finally, 8 September, the emperor embarked but soon turned back; therefore, on 29 September, the pope excommunicated him. Nevertheless, Frederick set sail again 18 June, 1228, but instead of leading a crusade he played a game of diplomacy. He won over Malek-el-Khamil, the Sultan of Egypt, who was at war with the Prince of Damascus, and concluded a treaty with him at Jaffa, February, 1229, according to the terms of which Jerusalem, Bethlehem, and Nazareth were restored to the Christians. On 18 March, 1229, without any religious ceremony, Frederick assumed the royal crown of Jerusalem in the church of the Holy Sepulchre.

at the Council of Lyons (June-July, 1245) Pope Innocent IV proclaimed a crusade, but the lack of harmony between him and the Emperor Frederick II foredoomed the pontiff to disappointment. Save for Louis IX, King of France, who took the cross in December, 1244, no one showed any willingness to lead an expedition to Palestine. On being informed that the Mongols were well-disposed towards Christianity, Innocent IV sent them Giovanni di Pianocarpini, a Franciscan, and Nicolas Ascelin, a Dominican, as ambassadors. Pianocarpini was in Karakorum 8 April, 1246, the day of the election of the great khan, but nothing came of this first attempt at an alliance with the Mongols against the Mohammedans. However, when St. Louis, who left Paris 12 June, 1248, had reached the Island of Cyprus, he received there a friendly embassy from the great khan and, in return, sent him two Dominicans. Encouraged, perhaps, by this alliance, the King of France decided to attack Egypt. On 7 June, 1249, he took Damietta, but it was only six months later that he marched on Cairo. On 19 December, his advance-guard, commanded by his brother, Robert of Artois, began imprudently to fight in the streets of Mansurah and were destroyed. The king himself was cut off from communication with Damietta and made prisoner 5 April, 1250. At the same time, the Ajoubite dynasty founded by Saladin was overthrown by the Mameluke militia, whose ameers took possession of Egypt. St. Louis negotiated with the latter and was set at liberty on condition of surrendering Damietta and paying a ransom of a million gold bezants. He remained in Palestine until 1254; bargained with the Egyptian ameers for the deliverance of prisoners; improved the equipment of the strongholds of the kingdom, Saint-Jean d'Acre, Cæsarea, Jaffa, and Sidon; and sent Friar William of Rubruquis as ambassador to the great khan. Then, at the news of the death of his mother, Blanche of Castile, who had been acting as regent, he returned to France. "
