The tribes in Awaran are divided into several clans. The main tribes in the district are Bizenjos, Mohammed Hasnis, Sajdis, Mirwanis, Rakhshani, Musianis, Sumalanies and Mengals.
The Bizenjos occupy the area along the banks of the Hingol river from Nal to the Jau valley. A considerable number of the Bizenjos is found in Kech and Awaran. They settled at the time of Mir Fakir Mohammed Bizenjo, the chief of the tribe.
The second main tribe in the area is Mohammed Hasnis. They live in the valley of Mashkai in the northern part of the district. The third major tribe in the area is known as Sajdis. The dominant sections of the tribe in the area are Sakazai, who seem really to be of Scythian origin. The Sajdi were true Balochs but, owing partly to inter-marriage, gradually amalgamated with the Brahvis. According to local accounts, the Sajdis first appeared 25 generations back, from the north, and established themselves in the Gichk valley near Panjgur.
Another tribe, i.e., Mirwanis is also famous in the area. It is an important Brahvi tribe. In the district, Mirwanis are principally found in Mashkai. The Mengals are also residing in the area, There are three distinct Brahvi tribes amongst Mengals. First is the Mengals of Khuzdar, second is the Mengals of Bolan, and third is the Mengals of Naushki. The Khuzdar Mengals are said to be Jadgals by origin. They are subdivided into the following branches. Shahizai, Pahlwanzai, Raisani, Baranzai, Mahmudzai, Mardoi, Sheikh, and Lehri. All of them, except the Lehris, are Raj-o-Kabila. Mengals take pride in some of their brave chiefs. At present Mengals are dominant in the district.
Awaran was notified as a separate district on 11th November 1992. Previously it was a sub-division of Khuzdar district. The old name of Awaran was Kolwa. The district consists of three tehsils – Mashkai, Awaran, Jhal Jhao –, eight patwar circles, and 204 mauzas.
