The Ghaznavid dynasty (Persian: غزنویان Ġaznaviyān) was a culturally Persianate, Sunni Muslim dynasty of Turkic mamluk origin, ruling, at its greatest extent, large parts of Persia, Khorasan, much of Transoxiana and the northwest Indian subcontinent from 977 to 1186. The dynasty was founded by Sabuktigin upon his succession to the rule of Ghazna after the death of his father-in-law, Alp Tigin, who was an ex-general of the Samanid Empire from Balkh, north of the Hindu Kush in Greater Khorasan.
