Mahmud of Ghazni or Mahmud Ghaznavi was the first independent ruler of the Turkic dynasty of Ghaznavids, ruling from 998 to 1030. At the time of his death, his kingdom had been transformed into an extensive military empire, which extended from northwestern Iran proper to the Punjab in the Indian subcontinent, Khwarazm in Transoxiana, and Makran.
Highly Persianized, Sultan Mahmud continued the bureaucratic, political, and cultural customs of his predecessors, the Samanids, which established the ground for a Persianate state in northwestern India. His capital of Ghazni evolved into a significant cultural, commercial, and intellectual centre in the Islamic world, almost rivalling the important city of Baghdad. The capital appealed to many prominent figures, such as al-Biruni and Ferdowsi.
Mahmud ascended the throne at the age of 27 upon his father's death, albeit after a brief war of succession with his brother Ismail. He was the first ruler to hold the title Sultan, signifying the extent of his power while at the same time preserving an ideological link to the suzerainty of the Abbasid Caliphate.
