Career
Having been imprisoned at the fortress of Barghund, he was one of the Ghaznavid princes that escaped the usurper Toghrul"s massacre in 1052. Following Farrukh"s death, Ibrahim was recognized as the last surviving male Ghaznavid. A military escort was sent to fetch him from Nay and he entered Ghazna on 6 April 1059.
Ibrahim"s reign was considered a golden age for the Ghaznavid empire, due to the treaties and cultural exchanges with the Great Seljuq empire.
Ibrahim was born during his father"s campaign into Gurgan and Tabaristan(c 1033). One of these daughters married the g-g-grandfather of the historian Juzjani.
Ibrahim"s son, Mas"ud, married Gawhar Khatun, daughter of Seljuq sultan Malik Shah, as a condition of peace between the Great Seljuq empire and the Ghaznavid empire. Every year Ibrahim would copy the Quran by hand and send it to the caliph in Mecca.
During an unknown date, Ibrahim also arrested his vizier Abu Sahl Khujandi for unknown reasons.
In 1060, at the request of the nobles of Ghur, Ibrahim invaded the region and deposed its ruler Abbas ibn Shith. He then had the latter"s son Muhammad ibn Abbas placed on the Ghurid throne. Following Mahmud"s successful campaigns into India, Ibrahim initially appointed him governor of India.
After 14 years of peace with the Great Seljuq empire, Ibrahim, in January 1073, sent an army into Sakalkand.
His army met with initial success capturing Seljuq sultan Malik Shah"s uncle, Uthman b. Chaghri beg, who was sent to Ghazna.
However, an army led by the Seljuq Amir Gumushtegin Bilge bey and Anushtegin Gharchai, drove out the Ghaznavid army that had devastated Sakalkand. In 1077/8, Ibrahim appointed Abd al-Hamid Shirazi as his vizier.
In 1079, Ibrahim led a campaign into India, besieging a fortress 120 Parasang(480 miles) from Lahore, taking it on 13 August 1079.
Ibrahim died on 25 August 1099 ending a reign of 41 years. His tomb lies in the northeastern part of medieval Ghazna near Shaikh Radi d-Din "Ali Lala"s tomb.
