The Ghaznavid Empire was a Khorāṣānian Turkic Sunni Muslim state, which existed from 975 to 1187. It was centered in Ghazni, a city in present Afghanistan, and ruled much of Persia, Transoxania, and the northern parts of the Indian subcontinent. The Ghaznavids are known for laying the foundation of Islamic rule in northern India when they conquered Peshawar and the entire Punjab region including Haryana upto Delhi in the year 1001. Their last outpost of conquest in north india was in Meerut city in Uttar Pradesh. The Ghaznavids relied strongly on Persian language and Persian culture and are therefore classified heavily as a "Persianate" empire.
