The state of Mekran was established in the eighteenth century by sardars of Mekran. It remained sovereign until 1948. On 17 March 1948, Mekran acceded to Pakistan, and on 3rd October 1952 it joined with Kalat, Kharan and Lasbela to form the Baluchistan States Union. From the last ruler of the Princely State of Mekran, on the accession to Pakistan, they did not accept Kalat’s hegemony and they declared their merging with newly born Muslim State of Pakistan.
The state was dissolved on 14 October 1955, when most regions of the western wing of Pakistan were merged to form the province of West Pakistan. When that province was dissolved in 1970, the territory of the former state of Mekran was organised as Mekran District and later Mekran Division of the province of Baluchistan (later changed to Balochistan).
The majority of the population of the province consisted of Baloch tribes with some other tribes such as Brahui (in the garb Baloch), Sindhi, Pukhtoon; Punjabi, Persian and Arabic speaking people.
