As these districts had originally been Afghan, they were transferred to British authority by the treaty of Gandamak in 1879, although nominally they had been handed over to Kalat forty years previously.
The Mingals, who, conjointly with the Brahuis, occupy the hills south of Kalat to the limits of the Rajput province of Las Bela, claim Mongolian descent, and traces of a Mongolian colony have been found in Makran.
The present name is a corruption of the Saracen Kalat-al-Girchc (the castle of Girche, the chieftain who fortified it).
The acropolis hill is now occupied by the ruins of Kalat el-Mudik.
From Kabul, on the N.E., it is distant 315 m., by Kalat-iGhilzai and Ghazni - Kalat-i-Ghilzai being 85 m., and Ghazni 225 m.
