Khusrau Shah was eldest and only surviving son of Bahram Shah.[1] Due to civil wars, tributary pact with Seljuk Empire and struggles with Ghurid Empire, Ghaznavid Empire was in its weakest times. Although his father tried to recapture the lost lands in India, he was stopped by Vigraharaja IV, an Indian king from Chahamanas dynasty.[2][3] His struggles with Ghurid Empire were also unsuccessful as he was defeated by two Ghurid Maliks.[4] Later he was defeated by Ala al-Din Husayn, who burned Ghazni for seven days.[5]
Bahram Shah recaptured Ghazni from Ghurids and later died in 1157. Nothing but few poems written by Hassan Ghaznavi remains about life of young Khusrau during reign of his father.[6] It seems that he was a hostage to the court of Saljuk emperor, Ahmad Sanjar.[7]
Reign
Khusrau Shah became sultan in 1157. Shortly afterwards, Ala al-Din Husayn ran a new campaign. Although Minhaj-i-Siraj stated that Ala al-Din Husayn already had captured the Ghaznavid possessions in southeastern Afghanistan, including Zamindawar, according to Bosworth it could be "an anticipation of what actually happened".[1]Fakhr-i Mudabbir stated a battle between two armies in which Khusrau Shah was defeated.[1] According to O'Neal, Khusrau Shah rebuilt army and moved towards west to capture the western lands of Ghurids, but faced with Ala al-Din army in Herat, he was defeated. He was forced to agree with pact that gives the Ghurids mentioned lands.[8]
Khusrau Shah's reign after war is mostly unknown, but it is known that he died in 1160[1] and was succeeded by his son Khusrau Malik, the last Ghaznavid Sultan, which was defeated by Ghurids and died sometime after 1184.[9]
Coinage
Few remaining Khusrau Shah coins stated Ahmad Sanjar as suzerain, although he died in 1157. Probably news of his death didn't reach Ghazni at the time.[1]
