The newly formed Bangladeshi armed forces incorporated some of the units and guerrillas of the Mukti Bahini. Gen. Osmani, who had led the Mukti Bahini was appointed the General of the Bangladesh armed forces. For many years, there was active discrimination in favour of the inductees from the Mukti Bahini against those Bengali officers who had continued service in the Pakistani armed forces or had been detained in West Pakistan. A group of angered officers assassinated the president Sheikh Mujib on 15 August 1975 and established a regime with politician Khondaker Mostaq Ahmed as President of Bangladesh and new army chief Maj. Gen. Ziaur Rahman. The military itself was subject of divisions as Mujib's assassins were overthrown by the pro-Mujib Brig. Gen. Khaled Mosharraf on 3 November, who himself was soon overthrown by a socialist group of officers under Col. Abu Taher on 7 November who returned Ziaur Rahman to power—an event now called the "Sipoy-Janata Biplob" ("Soldiers and People's Coup"). Under the presidency of Ziaur Rahman, the military was reorganised to remove conflicts between rival factions and discontented cadre. However, Ziaur Rahman was himself overthrown in a 1981 coup attempt, and a year later, Lt. Gen. Hossain Mohammad Ershad took power from the elected government of president Abdus Sattar. The military remained the most important force in national politics under the regimes of Ziaur Rahman and later Hossain Mohammad Ershad until democracy was restored in 1991.
