Bangladesh Liberation War
In 1971, the eastern wing of Pakistan broke away to become the independent state of Bangladesh. The nine-month conflict, which ended with direct Indian military intervention in December, redrew the map of South Asia, produced one of the worst episodes of mass violence of the late twentieth century, and sent millions of refugees across the border into India.
The roots of the war lay in the structure of Pakistan itself. Created in 1947, the country consisted of two regions separated by roughly 1,600 kilometers of Indian territory. East Pakistan held a majority of the population, yet political power, the army, and most economic investment were concentrated in the West. Resentment grew over the 1952 language movement, when Bengalis resisted the imposition of Urdu as the sole national language, and over perceived economic neglect. The Awami League, led by Sheikh Mujibur Rahman, campaigned for broad regional autonomy, and in the national elections of December 1970 it won an outright majority of seats in the parliament.
When the military government under Yahya Khan and political leaders in the West refused to let the Awami League form a government, unrest spread across the East. On the night of 25 March 1971, the Pakistan army launched a crackdown known as Operation Searchlight, beginning in Dhaka. Mujib was arrested, and independence was proclaimed in his name. Bengali soldiers, police, and civilians formed the Mukti Bahini resistance, and a government-in-exile was set up in territory across the Indian border. The army and allied local militias carried out widespread killings, sexual violence, and targeting of Hindus, students, and intellectuals. Estimates of the dead vary enormously, from the low hundreds of thousands to the three million often cited in Bangladesh, and the figure remains debated.
Around ten million people fled into India, creating a heavy burden that pushed Prime Minister Indira Gandhi toward intervention. After Pakistan launched air strikes on Indian airfields in early December, India entered the war openly. Its forces, working with the Mukti Bahini, advanced rapidly, and on 16 December 1971 Pakistani forces in the East surrendered in Dhaka. The Cold War shaped the diplomacy: the United States and China leaned toward Pakistan, while the Soviet Union backed India.
Bangladesh emerged as a sovereign state, with Mujib returning to lead it in early 1972. Pakistan, shaken by defeat, entered a period of political upheaval. Bangladesh has since pursued accountability through domestic war crimes trials, though these have drawn both support and criticism. The war is remembered in Bangladesh as a defining national struggle, and it remains a significant case in discussions of genocide and humanitarian intervention.
