Sheikh Mujibur Rahman (17 March 1920 – 15 August 1975), also known by the honorific Bangabandhu, was a Bangladeshi politician, revolutionary, statesman and activist who was the founding president of Bangladesh. As the leader of Bangladesh, he led the country as its president and prime minister from 1972 until his assassination in a coup d'état in 1975. His nationalist ideology, socio-political theories, and political doctrines are collectively known as Mujibism.
Born in an aristocratic Bengali Muslim family in Tungipara, Mujib emerged as a student activist in the province of Bengal during the final years of the British Raj. He was a member of the All-India Muslim League, supported Muslim nationalism, and advocated for the establishment of Pakistan in his early political career. In 1949, he became part of a liberal, secular and left-wing faction which later became the Awami League. In the 1950s, he was elected to Pakistan's parliament where he defended the rights of East Bengal. Mujib served 13 years in prison during the British Raj and Pakistani rule. By the 1960s, Mujib adopted Bengali nationalism and soon became the undisputed leader of East Pakistan. He became popular for opposing West Pakistan's political, ethnic and institutional discrimination against the Bengalis of East Pakistan; leading the six-point autonomy movement, he challenged the regime of Pakistan's President Ayub Khan. In 1970, he led the Awami League to win Pakistan's first general election. When the Pakistani military junta refused to transfer power, he gave the 7 March speech in 1971 where he vaguely called out for the independence movement. In the late hours of 25 March 1971, the Pakistan Army arrested Sheikh Mujib on charges of treason and carried out a genocide against the Bengali civilians of East Pakistan. In the early hours of the next day (26 March 1971), he issued the Proclamation of Bangladeshi Independence, which was later broadcast by Bengali army officer Major (later Lieutenant General) Ziaur Rahman on behalf of Sheikh Mujib, which ultimately marked the outbreak of the Bangladesh Liberation War. Bengali nationalists declared him the head of the Provisional Government of Bangladesh, while he was confined in a jail in West Pakistan.
