Al-Kamil becomes sultan of the Ayyubid dynasty.

Al-Malik al-Kamil Nasir ad-Din Muhammad, titled Abu al-Maʽali, 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 Frankish crusaders as Meledin, a name by which he is referred to in some older western sources. As a result of the Sixth Crusade, he ceded West Jerusalem to the Christians and is known to have met with Saint Francis.

Sultan is a position with several historical meanings. Originally, it was an Arabic abstract noun meaning "strength", "authority", "rulership", derived from the verbal noun سلطة sulṭah, meaning "authority" or "power". Later, it came to be used as the title of certain rulers who claimed almost full sovereignty without claiming the overall caliphate, or to refer to a powerful governor of a province within the caliphate. The adjectival form of the word is "sultanic", and the state and territories ruled by a sultan, as well as his office, are referred to as a sultanate.

The Ayyubid dynasty, also known as the Ayyubid Sultanate, was the founding dynasty of the medieval Sultanate of Egypt established by Saladin in 1171, following his abolition of the Fatimid Caliphate of Egypt. A Sunni Muslim of Kurdish origin, Saladin had originally served the Zengid ruler Nur al-Din, leading the latter's army against the Crusaders in Fatimid Egypt, where he was made vizier. Following Nur al-Din's death, Saladin was proclaimed as the first Sultan of Egypt by the Abbasid Caliphate, and rapidly expanded the new sultanate beyond Egypt to encompass most of Syria, in addition to Hijaz, Yemen, northern Nubia, Tripolitania and Upper Mesopotamia. Saladin's military campaigns set the general borders and sphere of influence of the sultanate of Egypt for the almost 350 years of its existence. Most of the Crusader states fell to Saladin after his victory at the Battle of Hattin in 1187, but the Crusaders reconquered the Syrian coastlands in the 1190s.
