Fifth Crusade

Called by the Fourth Lateran Council under Pope Innocent III, the Fifth Crusade abandoned the Fourth Crusade's direct Levantine target in favor of Egypt, judged by its planners to be the strategic key that would force the return of Jerusalem. Led in the field by the papal legate Cardinal Pelagius, King Andrew II of Hungary and, later, John of Brienne, titular King of Jerusalem, its multinational forces besieged and captured the Nile port of Damietta in 1219 after an eighteen month siege, facing the Ayyubid Sultanate under al-Adil and, from 1218, his son al-Kamil, who had succeeded to command of Egypt's defense during the long siege itself.

Before the crusaders' final advance toward Cairo, al-Kamil offered to trade Jerusalem itself for Damietta, an offer Pelagius, wielding the campaign's overall command as papal legate, refused outright. The crusader army pressed on regardless and was trapped by the annual Nile flood at al-Mansurah in 1221, forced to surrender Damietta and withdraw from Egypt entirely in exchange for its own survival. The campaign ended in failure, having come within one accepted offer of recovering Jerusalem by treaty rather than by the battle it never actually won on the ground.

The Fifth Crusade was directed by an ecumenical church council, the Fourth Lateran, and led in the field by a cardinal legate rather than any single monarch, making it among the most directly papally controlled of the numbered crusades to leave Western Europe. Cardinal Pelagius's own authority over strategy, including his refusal of al-Kamil's offer to trade Jerusalem for Damietta before the final advance on Cairo, reflected that centralized church direction as much as any purely military calculation made on the ground by the campaign's several lay commanders, King Andrew II and John of Brienne among them.

A separate episode from the same siege is documented apart from the fighting itself and from the campaign's ultimate failure at al-Mansurah: the Franciscan friar Francis of Assisi visited al-Kamil's own camp at Damietta during the crusade, an attempt at peaceful conversion rather than combat, made while the siege around them continued. The encounter sits alongside the campaign's ecclesiastical command structure as a reminder that the same crusade which failed militarily also produced one of the era's most striking recorded attempts at religious conversion by persuasion rather than by the sword its own army carried.
