Isma'il (surnamed Muntasir, "Victorious") (died January 1005)[1] was an individual who attempted to resurrect the Samanid state in Transoxiana and eastern Iran (1000–1005).
The approach of the Karakhanid army, however, forced Isma'il to give up all of his possessions, following which he travelled to Khurasan, which was controlled by the Ghaznavids under Mahmud of Ghazni's brother Nasr.
In 1003 Isma'il came back to Transoxiana, where he requested for and received assistance from the Oghuz Turks of the Zarafshan River valley.
He tried to gain Mahmud of Ghazni's support for a campaign to restore the Samanid state, but failed.
Descendants of the Samanid family continued to live in Transoxiana where they were well regarded, but their power was relatively broken.
