The Eighth Crusade was the second Crusade launched by Louis IX of France, this one against the Hafsid dynasty in Tunisia in 1270. It is also known as the Crusade of Louis IX against Tunis or the Second Crusade of Louis. The Crusade did not include any significant combat and Louis died by dysentery shortly after arriving on the shores of Tunisia. His army dispersed back to Europe soon after the Treaty of Tunis was negotiated.
