The Bangladesh Liberation War (1971)

Pakistan's first general election gave Sheikh Mujibur Rahman's Awami League 167 of the 169 seats allotted to East Pakistan, a clear majority in the National Assembly. West Pakistani political leaders and President Yahya Khan delayed the transfer of power and the convening of the Assembly, and the Assembly session summoned for March 1, 1971, was postponed, triggering a general strike and unrest in East Pakistan. Negotiations between the parties continued through March without agreement on the transfer of power.

Before a crowd of hundreds of thousands at the Ramna Race Course in Dhaka, Sheikh Mujibur Rahman declared, "This time the struggle is for our freedom," and called for resistance to the military regime. The speech is commemorated in Bangladesh as a founding moment of the independence movement. Negotiations with the regime continued for weeks after the speech but collapsed when the military crackdown began.

The Pakistani military launched Operation Searchlight, a crackdown aimed at suppressing the Bengali nationalist movement, beginning with assaults in Dhaka including an attack on Dhaka University. The violence that followed was directed against Awami League supporters, students, intellectuals, and the Hindu minority, and it drove a large part of the population toward the Indian border. On March 26, Major Ziaur Rahman broadcast a declaration of independence from Chittagong in Mujibur Rahman's name, and the Mukti Bahini (Bengali resistance forces) organized across the province.

The provisional government of Bangladesh was sworn in at Baidyanathtala (renamed Mujibnagar) in Meherpur district, with Tajuddin Ahmad as prime minister and Sheikh Mujibur Rahman, in Pakistani custody, as president. The government directed the Mukti Bahini's guerrilla campaign and conducted diplomacy seeking international recognition and support. India provided sanctuary and material support to the resistance while declaring a policy of non-recognition of the crackdown's outcomes.

By the middle of 1971 an estimated ten million people had fled East Pakistan for India, according to Indian government and international relief figures, with hundreds of thousands more displaced inside the province. The influx strained Indian border states and became a central element of the Indian government's stated case for intervention. Refugee accounts and international reporting documented killings and destruction in the province, while Pakistani authorities disputed the scale and character of the violence.

The Sunday Times published Anthony Mascarenhas' report "The Rape of Bangla Desh," the first full account by a Pakistani journalist of the military crackdown, based on his own reporting from the province before his departure. The article shifted international opinion and is credited with hardening the position of the British government and others against the Pakistani military action. Mascarenhas' family was moved into hiding after publication.

India and the Soviet Union signed the Treaty of Peace, Friendship and Cooperation, including a clause for mutual consultation in the event of a threat to either party. The treaty gave India diplomatic cover and military supply assurance as the crisis deepened, while the United States under the Nixon administration maintained its alignment with Pakistan and China cautioned against Indian action. The contrasting alignments turned the conflict into one of the Cold War's major proxy confrontations.

After the Pakistani air force struck Indian airfields in a series of pre-emptive attacks (Operation Chengiz Khan), India formally entered the war on both fronts and recognized the government of Bangladesh on December 6. Indian and Mukti Bahini forces advanced rapidly in East Pakistan while the United States dispatched the Seventh Fleet's Task Force 74 toward the Bay of Bengal in a show of support for Pakistan and the Soviet Union stood behind India. The campaign in the east was directed by Indian Lieutenant General Jagjit Singh Aurora and Bangladeshi commanders under the Mujibnagar government.

In the final days before the surrender, members of the Al-Badr militia, linked to the Pakistani military and Jamaat-e-Islami, abducted and killed a group of Bengali intellectuals, including professors, physicians, journalists, and writers. Mass graves discovered after the war and subsequent investigations documented the killings, and December 14 is observed in Bangladesh as Martyred Intellectuals Day. The targeting of intellectuals has been the subject of war crimes trials decades after the war.

Lieutenant General A. A. K. Niazi signed the Pakistani Instrument of Surrender at the Ramna Race Course in Dhaka in the presence of Lieutenant General Jagjit Singh Aurora, ending the war and the Pakistani military presence in the province. Approximately 93,000 Pakistani military and civilian personnel were taken as prisoners of war, and Bangladesh's independence was achieved. The repatriation of the prisoners, the fate of war crimes accountability, and the disputed accounting of the war's dead have shaped relations between the countries ever since.
