Al-Adil I (Sayf al-Din Abu Bakr)

Sayf al-Din Abu Bakr al-Adil, a younger son of Najm al-Din Ayyub and brother of Saladin, was the organizer and ultimately the refounder of the Ayyubid state. Born in 1145, probably in Damascus, he served throughout his brother's wars less as a battlefield commander than as the indispensable administrator: governor of Egypt during Saladin's long Syrian campaigns, master of its revenues, and the man who kept the war effort of 1187 to 1192 financed and supplied. Crusader chroniclers knew him as 'Saphadin,' and during the Third Crusade he became Saladin's principal channel to Richard I of England, conducting the negotiations that produced the Treaty of Jaffa — including the famous, unconsummated proposal that he marry Richard's sister Joan and rule a joint Jerusalem.

Saladin's death in 1193 fragmented the empire among his sons, with al-Afdal in Damascus, al-Aziz in Cairo, and az-Zahir in Aleppo. Al-Adil, holding lands in the Jazira, played the rivals against one another with unhurried skill for nearly a decade. By 1200 he had displaced his nephews from both Cairo and Damascus and proclaimed himself sultan, reuniting the core of the dynasty's territories and installing his own sons — al-Kamil in Egypt, al-Mu'azzam in Damascus, al-Ashraf in the Jazira — as its regional rulers. The arrangement gave the family confederation its mature form: a senior sultan in Cairo presiding over kinsmen-governors bound by loyalty and self-interest.

His reign was deliberately unheroic. Al-Adil pursued truces with the crusader states, encouraged Italian merchants in Alexandria and Damietta, reformed the coinage, and rebuilt fortifications from Cairo's citadel to Mount Tabor. He calculated that commerce served the dynasty better than jihad, and for nearly two decades the calculation held.

It failed at the end. The Fifth Crusade, summoned by Pope Innocent III, landed before Damietta in 1218 with Egypt itself as its target. Al-Adil, in his seventies, mobilized once more, but in August 1218, as news arrived that the crusaders had taken the chain tower commanding the Nile, the old sultan died — by some accounts of shock — at a camp in Syria. The crisis passed to his son al-Kamil, along with an empire that, for one more generation, his patient statecraft had made coherent.
