Bahram Shah was the son of Ghaznavid sultan Mas‘ud III (d. 1115/508 AH) and succeeded to the throne in 1117/511 AH reigning until 1152-1153/547 AH. After Mas‘ud’s death, there was a struggle for succession amongst his sons, where Shirzad (d. 1116/510 AH) and then Malik Arsalan (d. 1118/512 AH) ruled briefly [1].
