Brahuis of Kalat and Shah Hussain Hotaki
 

According to G.B. Malleson, (History of Afghans p-233) Mir Wais Hotaki after having captured Kandahar sought and enlisted the support of the Balochs and Tarins of Kalat and Quetta region.

But during the lifetime of Shah Hussain Hotaki , Khan of Kalat began encroachments on the Afghan area of Shal, Pishin and Shorawak. To recover the territories occupied by the Brahuis, Shah Hussain Ghilzai, in July 1733, crossed Khojak Pass and reached Pishin. Not finding the Brahuis there he followed them to Shal. The latter had taken position within a fort (on a mound or Kawatah) and sallied out under their leader Salar Khan, however, he was defeated. During the darkness of the night they vacated the place and made for Mastung and Kalat. Sher Dil Khan Babuzaey occupied the fort and Shah Hussain pushed on to Mastung. Prior to his arrival the Baloch had left Mastung. They divided themselves into two groups; one headed to Kalat and the other towards Gandawah Kachhi. The fugitives were overtaken at the boundary of Kalat district.

Major H.G. Raverty on page 611 and 612 of his Notes on Balochistan writes that the men took to the hills, leaving their families, cattle, and other property. The Afghans under Asadullah Khan Ishaqzaey Hotak took over every thing, and left the women and children unmolested. The Brahui Chief tendered allegiance. A treaty was concluded and out of the five clauses of this treaty one was that the Brahuis would return the cattle brought from Pishin and Shorawak. In 1737, the Baloch came in contact with Nadir Shah Afshar As the stories of the success of Nadir Shah Afshar spread, the Brahui Khans of Kalat abandoned the Afghans and went over to the side of the Persian despot.
