Esfarāyen

Esfarāyen was a town at the gateway to the northern mountains of Khorasan, held by the Qushji family after the Ilkhanate broke apart. In 1337 Shaykh 'Ali Qushji governed Khorasan for the claimant Togha Temür.

In July 1337 Arghun Shah of the Jauni Kurban captured and executed Shaykh 'Ali. Esfarāyen remained contested by Astarabad, the Sarbadars and the Jauni Kurban. In 1381 Timur sacked the town after Amir Vali refused him homage, bringing it under Timurid rule.
