The Capital City of the former state was the Chitral Town, which is situated on the west bank of the Chitral (or Kunar River) at the foot of Tirich Mir which at 7,708 m (25,289 ft) is the highest peak of the Hindu Kush. The borders of the state were seldom stable and fluctuated with the fortunes of Chitral's rulers, the Mehtars. The official language of the state was Persian, a legacy of the adaptation policy of the early Delhi Sultanate and Mughal times. The general population of the state was mainly of the Kho people, who spoke Khowar which is a Dardic language in the Indo-Aryan group. The Khowar language is also spoken in parts of Yasin, Gilgit and Swat.
