Louis IX, later canonized as Saint Louis, succumbed to dysentery in a camp outside Tunis while leading the Eighth Crusade. His death, alongside the collapse of the campaign, marked the effective end of large-scale French crusading efforts and became one of the defining moments of medieval French religious kingship.
Louis IX had already led one disastrous crusade decades earlier, been captured in Egypt, and ransomed at enormous cost. Undeterred, and driven by an almost fanatical piety, he launched a second expedition in 1270, this time aimed at Tunis, believing its ruler might be persuaded to convert to Christianity.
The campaign fell apart almost immediately. Disease tore through the crusader camp in the brutal North African summer heat, and Louis himself fell fatally ill with dysentery. He reportedly spent his final hours praying and reciting psalms, dying on a bed of ashes in a gesture of penitential humility.
His body was controversially divided for transport: his flesh was boiled off and buried locally while his bones were carried back to France for burial at Saint-Denis. Louis was canonized in 1297, becoming the only French monarch ever declared a saint, and his death effectively closed the era of major crusades launched from France.
