The Pope did initially approve the 5th Crusade in which Frederick took the cross. He kept putting it off and when he finally did go he turned around saying he was sick. He was then excommunicated by Gregory IX and later after he recovered (and married the Queen of Jerusalem) went on to the Holy Land as an excommunicate. Gregory IX was ticked off that an excommunicate was leading a crusade and asked the clergy in the Levant to not give Frederich II support. Seeing he had no real support (Templars and Hospitalers shunned him because they answered only to the Pope) he negotiated with Al-Kamil for the freedom of the city of Jerusalem.
