In 999–1004 AD a series of military campaign was led by the Ghaznavid dynasty under Mahmud of Ghazni, to seize control of Khorasan. Originally appointed as governors of Ghazni by the Samanids, the Ghaznavids, under Mahmud of Ghazni, formally demanded administrative control over Khorasan, which led the Ghaznavids annexing the region.

In the late 10th century the historical region of Khorasan was administrated by Ghaznavids under the Samanids. Mahmud who lost the control of the territory, demanded the charge of Khorasan to the Samanid Amir Mansur II. The Samanid empire, weakened by internal conflicts and external pressures, refused the demand. Despairing of getting back Khorasan by peaceful means, Mahmud decided to take it by force.
