[4] Bursuq is first recorded as the first shihna of Baghdad; he was appointed at the post by Tughril in April 1060 after the latter's domination of the Abbasid capital.
[4] Bursuq disappears from historical records for 15 years until 1078, this may be explained by Nizam al-Mulk's reforms which decreased the power of the emirs.
[4] In April 1087, during the marriage ceremony of the daughter of the Seljuk sultan Malikshah I and the Abbasid caliph al-Muqtadi (r. 1075–1094), Bursuq was among the emirs escorting the caravan of the bride to Baghdad.
His full support for Barkiyaruq proved to be rewarding as the sultan eventually became victorious and Bursuq strengthened his position in the Seljuk court.
Bursuq's sons and allies blamed Barkiyaruq's vizier Majd al-Mulk Qumi for involvement in the assassination and murdered him in 1099 in Sujas.
[4] One of Bursuq's daughters was married to Fakhr al-Dawlah Chawli, the Seljuk emir of Arrajan and nearby regions.
