Jahan Shah
In July 1457, the Timurid ruler of Transoxiana, Abu Sa'id Mirza, invaded. Abu Sa'id occupied Balkh but was unable to conquer Herat. 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. Jahan Shah entered Herat on June 28, 1458 but soon withdrew. Ibrahim was not able to recover his realm; Khurasan instead fell to Abu Sa'id Mirza.
