Babur's son Mirza Shah Mahmud had succeeded him but, as he was still a boy, his hold on power was weak.
Following the defeat of Shah Mahmud, Wajih al-Din Isma'il joined forces with Mirza Ibrahim, but was later imprisoned and tortured to death.
Soon after Jahan Shah of the Black Sheep Turkmen invaded as well and after occupying Gurgan, defeated Ibrahim outside Astarabad.
Ibrahim's father Ala al-Dawla Mirza met up with him in Herat to offer assistance, but in the end they both fled from the region.
The opposing forces met during the Battle of Sarakhs in March 1459, where Abu Sa'id defeated them.
