The area which covers the modern-day Pakistani province of Balochistan was first introduced to districts and divisions as administrative units under the British, and the area was first incorporated into British India in 1877.

[2] The first full census that was completed and had a report written on it took place in 1901.

[2] The administration given below: British Balochistan Province Balochistan Agency The Baluchistan Agency was split into three divisions: The areas directly administered by the British, the Native States, and the Tribal Areas.

[2] The areas directly administered by the British consisted of the Bolan Agency, the Chagai Agency (which consisted of Chagai, Nushki, and Western Sinjrani), the Quetta-Pishin Agency (which consisted of Quetta Tehsil excluding Shorarud), the Thal-Chotiali Agency (made of the Barkhan Tehsil, the Kohlu Sub-Tehsil, and the Sanjawi (Sinjawi) Sub-Tehsil), and the Zhob Agency (which included Fort Sandeman, Hindobagh, Loralai, Musakhel, and Qilla Saifullah Tehsils).

The tribal areas consisted of Baloch tribes which, as per the census report of 1901, exhibited "nomadic tendency to the largest degree".

[2] This meant that the administrative setup of the Balochistan region under British control was as follows in 1901:[2] By the time of the 1911 census, all the directly administered territories of the Baluchistan Agency had been abolished and reformed into districts in the Chief Commissioner's Province (British Baluchistan).

The two Tribal Areas of Bugti Country and Marri Country were also abolished as a separate unit and were made a part of Sibi District called Marri-Bugti Country (which became known the unadministered area of Sibi District, as opposed to the administered areas which covered parts of Thal-Chotiali District and Thal-Chotiali Agency).

[3] No changes occurred to the administrative setup of the Native Princely States, which now made up the entire Baluchistan Agency until 1940, when the State of Kharan gained complete independence from the Khanate of Qalat.

[4] This left the following administrative setup, which would see no changes through the 1921,[5] 1931,[6] and 1941 censuses,[4] all the way until Pakistani independence:[3][5][6] On 3 October 1952, the four princely states of Kalat, Kharan, Las Bela and Makran was merged to form Balochistan State Union with the capital at the town of Kalat.

On 1 July 1977, Makran was declared a division and was divided into three districts, named Panjgur, Turbat and Gwadar.
