After the death of Shams al-Din Ildeniz, in 1175, the Seljuq Sultan Arslan Shah tried to escape from the yoke of the Grand Atabeg of Azerbaijan but failed, and was poisoned to death by Shams ad-Din's son, the new Grand Atabeg Mohammed Jahan Pahlavan (1174-1186) [REF].
Jahan Pahlavan suppressed all rebellious emirs and appointed faithful mamluks to key positions.
