One of the last of Saladin's own amirs to keep his castles, Usama holds Ajlun, which he built in 1184 on a height over the Jordan valley to watch the Bedouin of the Jabal Awf, who had dealings with the Franks, and to guard the road between Damascus and Egypt and the iron mines of the hills; and Kawkab al-Hawa, the Hospitallers' Belvoir, which surrendered to Saladin on 5 January 1189 and commands the Jordan crossings south of the Sea of Galilee.
Al-Mu'azzam arrests him on his father's orders in 1211-1212; he dies a prisoner at Kerak.

Overlord
The Ayyubid prince of Damascus.
What it holds
How it was acquired
Built or granted under Saladin; confirmed in 1193.
Allies and rivals
A Salahi amir; later suspected by al-Adil. Neighbour of Safed and Tiberias.
How things stand that morning
Holds both castles.
Wealth
The iron of the Ajlun hills, the olives and grain of the Jabal Awf, the Jordan valley crossings.
Military
Ajlun (four corner towers, double gate, a moat about 16 m wide in its first form; enlarged only in 1214-1215) and Belvoir's concentric castle; garrisons of his own mamluks.
Threats
- Al-Adil's distrust of Saladin's old amirs (1211-1212).
Where the sources disagree
- Belvoir's slighting: Abu'l-Fida says Kawkab was razed by al-Adil's order after Usama's fall in 608 AH (1211-1212); the Belvoir Fortress article (Grove Encyclopedia) dates the slighting to 1219. Either way it stands in 1200.
Evidence: Abu'l-Fida names him for 1193 and 1211-1212; his part in 1199 is not recorded.
On the map: Castle districts are guesses round the castles.
