Mastung District in the context of Mastung, Pakistan

Brahui (Brahui: [braːhʋiː, braːhu.iː], English: /bɹəˈhuːi/ brə-HOO-ee; Brahui: براہوئی; also romanised as Brahvi or Brohi) is a Dravidian language which is primarily spoken in central and southern parts of the Pakistani province of Balochistan, with smaller communities in Iranian Baluchestan, Afghanistan, and Turkmenistan (around Merv). Expatriate Brahui communities also exist in Iraq, Qatar, and the United Arab Emirates. Brahui is geographically isolated from other Dravidian languages, with the nearest being over 1,500 kilometres (930 mi) away in South India. The Kalat, Khuzdar, Mastung, Quetta, Bolan, Nasirabad, Nushki, and Kharan districts of Balochistan Province are predominantly Brahui-speaking.

Brahui is the only Dravidian language that is primarily written in the Perso-Arabic script. It is also written in the Latin script.

Kalat District (Brahui and Urdu: قلات) is a district located in Kalat Division of Balochistan, Pakistan. Kalat was made a separate district on February 3, 1954. At that time Khuzdar and Mastung districts were sub-divisions of Kalat (which then also included Kachi, Jhal Magsi and Naseerabad (Dera Murad Jamali); these were separated in 1965 as Kachhi District). Khuzdar became a separate district by notification of 1 March 1974, while Mastung was announced as a separate district on 18 February 1992. The district draws its name from the ancient city of Kalat. The old name of the district headquarters was Kahan. The current district consists of two sub-divisions, i.e. Kalat and Manguchar, four tehsils: Kalat, Mangochar, Johan, and Gazgz, 81 Patwar circles and 614 mauza (villages).

The climate is arid, hot in summer and cold in winter, with most rainfall occurring in the winter. The terrain is mountainous with several valleys and one main river. The Khan of Kalat is a ceremonial title held by Mir Suleman Dawood Jan, and efforts have been made by the Pakistani government to reconcile with him; his son Mohammed, who is next in line to be the Khan of Kalat, is pro-Pakistan.
