Defence Secretary (1947–54) He was appointed as the first
Defence Secretary in the Liaquat administration by the Prime Minister
Liaquat Ali Khan, who relied on running the government on the British viceregal model with the close coordination of the
civilian bureaucracy, the
police, and the
military. As Defence Secretary, he oversaw the military efforts in the
first war with India in 1947, as well as witnessing the
failed secession in
Balochistan by
Khan of Kalat. In 1950, Mirza was promoted to
two-star rank, having skipped the one-star promotion as
brigadier, and upgraded his rank to
major-general in the
Pakistan Army by the promotion papers approved by Prime Minister Ali Khan. He was appointed as
colonel commandant of the
Military Police while serving as the Defence secretary in the Liaquat administration. In 1951, Prime minister Ali Khan appointed him as the director of the Department of Kashmir and Afghanistan Affairs (DKA). His tenure as defense secretary also saw the deployment of Military Police in
East Pakistan (now Bangladesh) as a result of the
Bengali language movement, during which the
East Pakistan Rifles fatally shot four student activists. Within a short span of time, the Military Police had control of the state and its commanding officer submitted the report of their course of action to Major General Iskander Mirza in 1954. For the
four-star appointment, the
Army GHQ sent the nomination papers to the
Prime Minister's Secretariat that included four-senior
major-generals in the race for the
army command of the Pakistan Army: Major-General
Iftikhar Khan, Major-General
Akbar Khan, Major-General
Ishfakul Majid, and Major-General
N.A.M. Raza. Initially, it was Major-General
Iftikhar Khan who was promoted to four-star rank and selected to be appointed as the first native commander of the army but died in an airplane crash en route after finishing the senior
staff officers' course in the United Kingdom. All three remaining major-generals were bypassed including the recommended senior-most Major-General
Akbar Khan and Major-General
Ishfakul Majid due to Major-General Mirza's lobbying for the army selection when he presented convincing arguments to Prime Minister
Ali Khan to promote the junior-most Major-General
Ayub Khan to the post despite the fact that his name was not included in the nomination list.
Governorship of East Bengal and Cabinet Minister (1954–55) , as the Governor General of Pakistan Due to rapid political instability in
East Bengal, Mirza was relieved as
Defence Secretary and took over the governorship of East Bengal, in an appointment approved by then
Governor-General Sir Malik Ghulam on 29 May 1954. On 1 June 1954, Mirza took over the
Government of East Bengal from Chief Minister
A. K. Fazlul Huq as part of the
governor's rule that dismissed the
United Front. He imposed
martial law, backed by the
East Pakistan Rifles, and dismissed the
East Bengal Legislative Assembly. On 24 October 1954, he was appointed as
Interior Minister in the
Bogra administration of Prime Minister
Mohammad Ali Bogra. During this time, he had maintained close political ties to the United States's establishment and was backed by Governor-General
Sir Malik Ghulam for this post, which Mirza only remained at until 7 August 1955. During this time,
Governor-General Malik Ghulam survived another attack of
paralysis that made him unable to talk and walk, seeking treatment in the United Kingdom on a two-month leave. Appointed only as
acting governor-general since 7 August 1955, Mirza dismissed
Sir Malik Ghulam to take over his post on 6 October 1955, and
forced Prime Minister Bogra to resign when he appointed him as the
Pakistan Ambassador to the United States. On 12 August 1955, he invited
Muhammad Ali, the
Finance Minister, to take over the government as a prime minister. ==Presidency (1956–58)==
