Mansur's oppressive taxation policies had sparked a revolt in Sistan within a year of his appointment.

The garrison at Zaranj was destroyed, and Mansur was captured.

Amr ibn Ya'qub, a Saffarid, was installed, first as a puppet for the leader of the rebellion, then as amir in his own right.

A Samanid army, however, under the control of Husain ibn 'Ali Marvarrudhi restores Samanid control to the region.

'Amr is sent to Samarkand; the other rebel leaders are killed.
