What happened

Twenty years after his capture in Egypt, Louis IX of France launched a second crusade in 1270, this time aiming first at Tunis in North Africa as a staging point for a future assault on Egypt. His son John Tristan and much of the army were struck down by disease and lack of clean water in the summer heat at their camp near Carthage. Louis himself contracted dysentery, and after a month of illness he died on 25 August 1270. According to legend, though not according to the confessor actually present at his deathbed, his final words were "Jerusalem! Jerusalem!" Charles of Anjou took command after Louis's death and negotiated a withdrawal from the Emir of Tunis in exchange for the release of Christian prisoners and a large payment of gold. A storm then wrecked much of the returning fleet off Sicily, and the crusade dissolved without ever reaching the Holy Land.

Why it matters

The Eighth Crusade's collapse from disease before a single major battle was fought marked one of the bleakest outcomes of the entire crusading era, and it was the last crusade any French king would personally lead to the East.

How we know

Louis's illness and death are described in the World History Encyclopedia's account of the campaign, including the detail, explicitly flagged as legend rather than fact, that his confessor did not record the famous last words attributed to him.
