The Eighth Crusade was a crusade launched by Louis IX of France against the Hafsid dynasty in 1270. The Eighth Crusade is sometimes counted as the Seventh, if the Fifth and Sixth Crusades of Frederick II are counted as a single crusade. The Ninth Crusade is sometimes also counted as part of the Eighth. The crusade is considered a failure after Louis died shortly after arriving on the shores of Tunisia, with his disease-ridden army dispersing back to Europe shortly afterwards.
