Jhalawan (Urdu: جھالاوان) was an administrative division of the Khanate of Kalat, a princely state that joined Pakistan in 1947. It was established in the 17th century and its boundary was fixed with Sindh in 1853. It was located in the southeastern part of Kalat State, north of Las Bela, west of the Kachi and Sindh and east of the Kharan and Makran. Jhalawan has important valleys of Baluchistan, such as Kalat, Gidar, Baghbana, Mola Valley, Zehri, Firozabad valley, Wadh, Nal, Saruna, Jau and the Mashkai river. In Jhalawan, Khuzdar is the city that is the second largest city of Balochistan Province.Nawab Sanaullah Khan Zehri (Urdu: نواب ثناء اللہ زہری ) is the tribal leader of Zehri tribe. he is the current chief or nawab of all the tribes in Jhalawan.
In the 15th century, the country fell under the control of Mirwari. They governed an area extending from a region near Surab (Nighar) to the hills of Jhalawan. Before Mir Khudadad Khan, the country was a part of Kalat state for many years, but Mir Khudadad Khan's rule brought a period of unrest in the region. This resulted in a number of Jhalawan tribesmen revolting against Mir Khudadad Khan's reign; their chief, Taj Muhammad Zarakzai was strangled as a consequence.
