3 September 1216. The Roman people were greatly elated at the election, for Honorius III was himself a Roman and by his extreme kindness had endeared himself to the hearts of all. Fifth Crusade The Fifth Crusade was endorsed by the Lateran Council of 1215, and Honorius started preparations for the crusade to begin in 1217. To procure the means necessary for this colossal undertaking, the Pope, and the cardinals were to contribute the tenth part of their income for three years. All other ecclesiastics were to contribute the twentieth part. Though the money thus collected was considerable, it was by no means sufficient for a general crusade as planned by Honorius III. Far-reaching prospects seemed to open before him when Honorius crowned Peter II of Courtenay as Latin Emperor of Constantinople in April 1217, but the new Emperor was captured on his eastward journey by the despot of Epirus, Theodore Komnenos Doukas, and died in confinement. In July 1216, Honorius once again called upon Andrew II of Hungary to fulfill his father's vow to lead a crusade. (Béla III willed property and money to Andrew, obliging him to lead a crusade to the Holy Land.) Like many other rulers, his former pupil, the Emperor Frederick II of Germany, had taken an oath to embark for the Holy Land in 1217. But Frederick II hung back, and Honorius III repeatedly put off the date for the beginning of the expedition. In spite of the insistence of Honorius III, Frederick II still delayed, and the Egyptian campaign failed miserably with the loss of Damietta on 8 September 1221. Most rulers of Europe were engaged in wars of their own and could not leave their countries for any length of time. King Andrew II of Hungary and, somewhat later, a fleet of crusaders from the region along the Lower Rhine finally departed for the Holy Land. They took Damietta and a few other places in Egypt, but a lack of unity among the Christians and rivalry between their leaders and the papal legate Pelagius resulted in failure. 24 June 1225 was finally fixed as the date for the departure of Frederick II, and Honorius III brought about his marriage to Queen Isabella II of Jerusalem with a view to binding him closer to the plan. But the Treaty of San Germano in July 1225 permitted a further delay of two years. Frederick
