Al-Kamil

Al-Malik al-Kamil Nasir ad-Din Muhammad (Arabic: الملك الكامل ناصر الدين محمد; c. 1177 – 6 March 1238), titled Abu al-Maʽali (Arabic: أبي المعالي), was an Egyptian ruler and the fourth Ayyubid sultan of Egypt. During his tenure as sultan, the Ayyubids defeated the Fifth Crusade. He was known to the Latin/Frankish crusaders as Meledin, a name by which he is usually referred to in older Western sources and often but less frequently continues to be. As a result of the Sixth Crusade, he ceded West Jerusalem to the Christians and is known to have met with Saint Francis.
