Balochistan or Baluchistan (Balochi: بلوچستان) (lit. Land of the Baloch) is an arid, desert and mountainous region on the Iranian plateau in south-western Asia, northwest of the Arabian Sea. It mainly includes southwestern Pakistan, southeastern Iran and a very small section of southwestern Afghanistan. The southern part of Balochistan is known by its historical name Makran.
Balochistan is named after the native Baloch tribes who make up the inhabitants in the region and use Balochi as their native language. Persian, Pashtu and Urdu are also used as second language depending on where they live, Brahui is spoken by Brahui minority.
The Baloch people once referred to their land as Moka or Maka, a word which later became Makran. Balochistan is referred to in Pashto as Gwadar or Godar (also Godar-khwa, i.e., the land by water). This the Greeks, who derived the names of Iranian lands from the Bactrian language, Hellenised to Gedrosia. It thus appears that the name Balochistan is a relatively recent arrival on the scene.
