Treaty of Tunis Ends the Eighth Crusade
On October 30, 1270, the Treaty of Tunis was concluded, bringing the Eighth Crusade to an end. Louis IX of France had launched the campaign against the Muslim-ruled city of Tunis, but disease ravaged the crusading army and the king himself died in August. The treaty allowed Christians some commercial and religious privileges in Tunis in exchange for withdrawing their forces. According to medieval chronicles, it marked a sobering realization in Europe that crusading fervor no longer guaranteed military success in North Africa and the eastern Mediterranean.
