A decisive battle occurred just outside Ghazna on the plain of Shahrabad, again resulting in Arslan's defeat and he fled to the Ghaznavid territories in northern India.

[5] Bahram entered Ghazna, in the company of Sanjar, and was formally installed as sultan in 1117, but as a vassal of the Great Seljuq Empire.

After sending diplomatic entreaties, Bahram was assured of his throne, his position as a tributary of the Seljuq empire and returned to Ghazna.

Between 1143 and 1146, Bahram commissioned Abu'l-Ma'ali Nasrallah to translate the Indian fable story Kalila wa Dimna from Arabic to Persian.

[12] In an attempt to strengthen his hold over the Ghurids, Bahram invited Qutb ad-Din Muhammad b. Husain, his son in law, to court.

By 1148, Sayf al-Din Suri returned with an army, scored a victory at the Battle of Ghazni while Bahram fled to Kurram.

Bahram rallied elements of his army at the hot springs, Jush-i Ab-i Garm, but was again routed and fled back to Ghazna.

After the defeat and capture of Ala al-Din Husayn at Herat by Seljuq forces, Bahram returned to Ghazna and removed the Ghurid governor.

[19] According to Mihaj's Tabaqat-i Nasiri and Firishta's Tarikh-i-Firishta, Muhammad Bahlim or Bahalim (Bahram Shah's governor in India) had captured the Nagaur fort.

[20] Nagaur was under the control of the Chahamana king Ajayaraja at least until 1121 CE, as attested by Prabhavaka Charita (the text calls him Alhadana, which appears to be a Sanskritized form of his alias Alhana).

After defeating these invaders, Arnoraja purified the place of their death by commissioning a lake, which is identified with the modern Ana Sagar.

R. B. Singh speculates that after revolting against Bahram Shah, Bahlim sought asylum with the Chahamanas, and Arnoraja granted him the fief of Nagaur.

[23] According to Bertold Spuler, a German Orientalist, Bahram's treachery, personal cowardice and desertion of his subjects directly contributed to the disintegration of the Ghaznavid Empire.
