The Martial Law Administrator of Balochistan was the head of the military regime of Balochistan, the largest province of Pakistan.
 The capacity was first established when martial law was imposed by General Yahya Khan, who appointed Riaz Hussain to the post, but was never officially ratified.
 It therefore lapsed when Yahya resigned.
 The post was officially in operation from July 1977, when martial law was imposed again, until late 1985, when it was informally terminated upon the lifting of martial law by Prime Minister Muhammad Khan Junejo.
 The martial law administrator was a serving Lieutenant General of the Pakistan Army, appointed by the Chief of Army Staff.
 General Muhammad Zia-ul-Haq was the incumbent in each instance.
 When the presidential term of Fazal Ilahi Chaudhry ended, the post assumed the political office of Governor of Balochistan; the civilian Chief Justices who were acting as governors of the provinces were replaced by their martial law counterparts.
 Of the three officeholders, none completed their designated term.
Operation Searchlight was a planned military operation carried out by the Pakistan Army to curb the Bengali nationalist movement in the erstwhile East Pakistan in March 1971, which the Pakistani state justified on the basis of anti-Bihari violence by Bengalis in early March.
 Ordered by the central government in West Pakistan, this was seen as the sequel to "Operation Blitz" which had been launched in November 1970.
 The original plan envisioned taking control of the major cities on 26 March, and then eliminating all opposition, political or military, within one month.
 President Yahya Khan at a conference in February 1971 said "Kill three million of them and the rest will eat out of our hands."
 Prolonged Bengali resistance was not anticipated by the Pakistani military leaders.
 The main phase of Operation Searchlight ended with the fall of the last major town in Bengali hands in mid-May.
 The operation also precipitated the 1971 Bangladesh genocide and caused roughly 10 million refugees to flee to India as well as the death of up to 3,000,000 civilians.
 Bengali intelligentsia, academics and Hindus were targeted for the harshest treatment, with significant indiscriminate killing taking place.
 These systematic killings enraged the Bengalis, who declared independence from Pakistan, to establish the new state of Bangladesh.
