The Bangladesh Liberation War lasted for nine months. The Bangladesh Forces formed within 11 sectors led by General M.A.G. Osmani consisting of Bengali Regular forces conducted a massive guerilla war against the Pakistan Forces with support from the Mukti Bahinis consisting of Kaderia Bahni, Hemayet Bahini, and others financed and equipped by Indian Armed Forces Maj. Gen. Sujat Singh Uban. The Indian Army, assisted by Bangladeshi forces, negotiated a cease-fire and surrounded the Dhaka Area. The Indian Army remained in Bangladesh until 19 March 1972.
After its independence, Bangladesh was governed by an Awami League government, with Mujib as the Prime Minister, without holding any elections. In the 1973 parliamentary elections, the Awami League gained an absolute majority. A nationwide famine occurred during 1973 and 1974, and in early 1975, Mujib initiated a one-party socialist rule with his newly formed BAKSAL. On 15 August 1975, Mujib and most of his family members were assassinated by mid-level military officers. Vice President Khandaker Mushtaq Ahmed was sworn in as President with most of Mujib's cabinet intact. Two Army uprisings on 3 November and the other on 7 November 1975 led to the reorganised structure of power. Emergency was declared to restore order and calm, Mushtaq resigned and the country was placed under temporary martial law, with three service chiefs serving as deputies to the new president Justice Abu Satem, who also became the Chief Martial Law Administrator. Lieutenant General Ziaur Rahman, took over the presidency in 1977 as Justice Sayem resigned. President Zia reinstated multi-party politics, introduced free markets, and founded the Bangladesh Nationalist Party (BNP). Zia's rule ended when he was assassinated by elements of the military in 1981.
Bangladesh's next major ruler was Lieutenant General Hossain
