Forced out of
Transoxiana in 1034 by the
Kara-Khanids, the Seljuks settled in
Khwarazm under the advocacy of the Ghaznavid governor Harun. His murder in 1035, forced them to flee through the
Kara Kum Desert towards Merv, but they switched instead to Nasa on the edges of
Khurasan. Hearing of this threat, Ghaznavid sultan
Ma'sud I sent Iltughdi with a large army to Nasa. Initially successful having driven off the Seljuk forces, the Ghaznavid army began squabbling over the spoils. The Seljuk, led by Chaghri, returned and fell upon the disorganized Ghaznavids and defeated them. As a result, Ma'sud entitled the Seljuk to three cities in Khurasan: Dihistan, Nasa, and Farawa. After conducting raids as far as Balkh, all of Khurasan fell to the Seljuk Turks. ==Battle==
