The Ghaznavid dynasty or the Ghaznavid Empire was a Persianate Muslim dynasty and empire of Turkic mamluk origin, ruling at its greatest extent, large parts of Iran, Khorasan, 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.

Persian, also known by its endonym Farsi or Parsi, is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, respectively Iranian Persian, Dari Persian, and Tajiki Persian. It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivative of the Arabic script, and within Tajikistan in the Tajik alphabet, a derivative of the Cyrillic script.
