The Eighth Crusade was Louis IX's second and final crusade, redirected from its original target in the Holy Land to Tunis in North Africa on the advice of his own brother Charles of Anjou, King of Sicily, who hoped to draw the Hafsid ruler of Tunis, Muhammad I al-Mustansir, into an alliance or tribute relationship rather than fight a war for Jerusalem at all in this second expedition.

The crusading army landed near Tunis in July 1270, but dysentery swept through the camp within weeks, killing Louis himself on 25 August 1270 before any significant engagement with Hafsid forces ever took place on the ground. Charles of Anjou negotiated a tribute treaty with the Hafsids and withdrew the remaining crusader force soon after his brother's death, ending the campaign with no territorial or religious gain toward the Holy Land it had nominally been raised to help recover, its own king dead of disease rather than in any battle fought in his name. The Tunis expedition therefore ended without the crusading army ever facing the Hafsid forces it had been raised to fight, disease alone having accomplished what the campaign's own planners had never anticipated when they first redirected it away from the Holy Land.

The Eighth Crusade was preached and organized as a direct continuation of Louis IX's earlier crusading vow, but contemporary and later chroniclers alike already debated Charles of Anjou's own political and commercial motives in redirecting the expedition to Tunis, since a tribute treaty with the Hafsids served Sicilian trade interests as readily as any religious object the crusade nominally pursued in Louis's own name and honor.

Louis's own death during the campaign, from dysentery before the army ever engaged Hafsid forces in any real battle, was quickly assimilated into his later canonization as Saint Louis by the church he had served. A crusade which achieved no territorial or religious gain toward Jerusalem itself came instead to be remembered chiefly through the sanctity of the king who died upon it, a shift from military failure to devotional memory that historians treat as part of the campaign's own lasting afterlife in later medieval and Catholic tradition. The distance between the crusade's stated religious purpose and its brother's own commercial diplomacy at Tunis is one reason historians treat the Eighth Crusade as marking a real turning point in the crusading movement's credibility among its own contemporaries.
