of the territory of modern-day Balochistan province in Pakistan. To the north was Baluchistan (Chief Commissioner's Province). The principal mountains are the Central Baloch, Kirthar, Pab, Siahan, Central Makran and Makran Coast Ranges, which descend in elevation from about 10,000 to . The drainage of the country is almost all carried off to the south by the Nari, Mula, Hab, Porali, Hingol and Dasht rivers. The only large river draining northwards is the Rakhshan. The coast line includes Gawadar, Pasni, Sonmiani and Geewani, modern-day Pakistani Balochistan. Subdivisions Jhalawan, an ethnic Brahui subdivision, headed by the chief nawab of the Zarakzai tribe, known as Chief of Jhalawan Kacchi, an ethnic Sindhi subdivision, in which various tribes had their own tribal lands under the Khan of Kalat Sarawan, an ethnic Baloch subdivision, headed by chief nawab of Raisani tribe, called chief of Sarawan Dushka H Saiyid emphasizes that Yar Khan lost all of his bargaining chips with the accession of Kharan, Las Bela, and Mekran leaving Kalat as an island. Salman Rafi Sheikh largely concurs with Saiyid's assessment: multiple other Kalat sardars were preparing to accede to Pakistan and Yar Khan would have hardly any territory left, if he did not accede. On 3 October 1952, the state of Kalat entered into the Baluchistan States Union with three neighbouring states, Kharan, Las Bela, and Makran, with Yar Khan of Kalat at the head of the Union with the title of Khan-e-Azam. The Khanate came to an end on 14 October 1955, when it was incorporated into West Pakistan. Rulers of Kalat The rulers of Kalat at first held the title of Wali but in 1739 also took the title of (Begler Begi Khan), usually shortened to Khan. The last Khan of Kalat () had the privilege of being the President of the Council of Rulers for the Baluchistan States Union. They also had the title of beylerbey.
