Ghiyas-uddin Pir 'Ali had been made Timur's…

Ghiyas-uddin Pir 'Ali had been made Timur's vassal, until he supported a rebellion in 1382 by the maliks of Herat.

Ghiyas-uddin Pir 'Ali and his family are executed around 1383, and Timur's son Miran Shah destroys the revolt.

This same year, a new uprising led by a Shaikh Da'ud-i Khitatai in Isfizar, to the west of Herat, is quickly put down by Miran Shah.
