What happened in fifth crusade?

The Fifth Crusade (1217-1221) aimed to recapture Jerusalem by first conquering Egypt, which was seen as a key to controlling the Holy Land. Crusaders captured the port city of Damietta in 1219 but faced difficulties advancing further. Despite initial successes, a failed siege of Cairo and subsequent losses led to the eventual withdrawal of the crusading forces. The campaign ultimately ended in failure, with many crusaders dying or returning home disillusioned.
