Sheikh Mujibur Rahman who won the 1970 Pakistani general election, was denied by the Pakistani military dictatorship to become the Prime Minister of Pakistan; this was a result of long time political oppression of Bengali citizens of Pakistan who were vocally opposed to the authoritarian tyranny of the The Establishment (Pakistan). As the democratic demands and protests continued, Sheikh Mujibur Rahman delivered the speech on 7 March that brought the Bengalis together to become prepared for things to come. On 25th March of 1971, the Pakistan Army, launched an armed operation killing intellectuals in Dhaka University and the next day on 26th March 1971 Sheikh Mujibur Rahman declared Bangladesh's independence from Pakistan, triggering the 9-month Bangladesh Liberation War that ended with the surrender of Pakistani forces in Bangladesh to an allied force of Bangladesh Mukti Bahini and Indian Armed forces. In 1973, Sheikh Mujibur's Bangladesh Awami League won the first parliamentary election in independent Bangladesh by a landslide.
