The Baloch rebellion of the 1970s was the most-threatening civil disorder to Pakistan since Bangladesh's secession. The Pakistan Armed Forces wanted to establish military garrisons in Balochistan Province, which at that time was quite lawless and run by tribal justice. The ethnic Balochis saw this as a violation of their territorial rights. Emboldened by the stand taken by Sheikh Mujibur Rahman in 1971, the Baloch and Pashtun nationalists had also demanded their "provincial rights" from then-Prime Minister Zulfikar Ali Bhutto in exchange for a consensual approval of the Pakistan Constitution of 1973. But while Bhutto admitted the North West Frontier Province (NWFP) and Balochistan to a NAP-JUI coalition, he refused to negotiate with the provincial governments led by chief minister Ataullah Mengal in Quetta and Mufti Mahmud in Peshawar. Tensions erupted and an armed resistance began to take place.
