East Pakistan declares its independence from Pakistan to form the People's Republic of Bangladesh and the Bangladesh Liberation War begins.

The geopolitical landscape of South Asia underwent a profound transformation in the mid-20th century, notably with the emergence and eventual secession of East Pakistan. Established in 1955, East Pakistan was a province of Pakistan, forged by the controversial One Unit Policy which renamed the former East Bengal. This region, now largely encompassed by independent Bangladesh and a portion of India, shared its land borders with India and Burma, while boasting a significant coastline along the Bay of Bengal. Its people were widely known as "Pakistani Bengalis," a distinct identity carved out to differentiate the region from India's West Bengal, often referred to simply as "Indian Bengal." Tragically, this identity and the region's very existence as East Pakistan came to a dramatic end in 1971, culminating in the birth of the sovereign nation of Bangladesh.

The Genesis and Political Turmoil of East Pakistan

The formal renaming from East Bengal to East Pakistan was a direct result of Pakistani Prime Minister Mohammad Ali of Bogra's One Unit scheme, an attempt to streamline the administrative divisions of the nascent nation. The political journey of Pakistan, and by extension East Pakistan, was marked by significant upheaval. The Constitution of Pakistan in 1956 transformed the monarchy into an Islamic republic. During this period, prominent Bengali politician H. S. Suhrawardy served as Prime Minister of Pakistan from 1956 to 1957, while Bengali bureaucrat Iskander Mirza made history as the first President of Pakistan. However, this democratic facade was short-lived. A military coup in 1958 brought General Ayub Khan to power, who swiftly replaced Mirza as president and initiated a severe crackdown on pro-democracy leaders. Khan further consolidated his authority by enacting the Constitution of Pakistan of 1962, which controversially ended universal suffrage, disenfranchising a large segment of the population.

By 1966, Sheikh Mujibur Rahman, a charismatic and influential Bengali leader, had emerged as the preeminent opposition figure in Pakistan. He launched the historic six-point movement, advocating for greater autonomy and democracy for East Pakistan. The mounting discontent culminated in the 1969 uprising in East Pakistan, which ultimately contributed to Ayub Khan's overthrow. His successor, General Yahya Khan, usurped the presidency and immediately imposed martial law. In a pivotal moment in 1970, Yahya Khan organized Pakistan's first federal general election. The Awami League, led by Sheikh Mujibur Rahman, achieved a landslide victory, emerging as the single largest party, followed by the Pakistan Peoples Party. Yet, the military junta's refusal to accept these democratic results ignited widespread civil disobedience, setting the stage for the devastating Bangladesh Liberation War and the horrific 1971 Bangladesh genocide. With crucial support from India, East Pakistan bravely seceded from Pakistan.

Economy and Development Amidst Disparity

East Pakistan held significant strategic importance, which was reflected in the Pakistani union's membership in the Southeast Asia Treaty Organization (SEATO). Economically, the region experienced an average growth rate of 2.6% between 1960 and 1965. Despite generating a major share of the nation's exports, East Pakistan found itself at a disadvantage; the federal government consistently invested more funds and foreign aid into West Pakistan, exacerbating regional disparities. Nevertheless, President Ayub Khan did oversee some significant industrialization initiatives within East Pakistan. Notably, the Kaptai Dam was constructed in 1965, and the Eastern Refinery was established in Chittagong, contributing to the region's infrastructure. Dacca, the heart of East Pakistan, was even declared the second capital of Pakistan and was envisioned as the future home of the national parliament, with the acclaimed American architect Louis Kahn recruited to design the ambitious national assembly complex.

The Bangladesh Liberation War: A Fight for Independence

The Bangladesh Liberation War, known in Bengali as the Mukti Juddho ([muktiuddo]), or simply the War of Independence, was a profound revolution and armed conflict. It was ignited by the fervent rise of the Bengali nationalist and self-determination movement within erstwhile East Pakistan, ultimately leading to the independence of Bangladesh. The war began on the night of March 25, 1971, when the Pakistani military junta, based in West Pakistan and acting under the direct orders of Yahya Khan, launched "Operation Searchlight" against the people of East Pakistan. This brutal military action initiated the tragic Bangladesh genocide, a systematic annihilation campaign targeting nationalist Bengali civilians, students, intellectuals, religious minorities, and armed personnel. The junta brazenly annulled the results of the 1970 elections and arrested the prime minister-designate, Sheikh Mujibur Rahman. The devastating conflict finally concluded on December 16, 1971, when the military forces of West Pakistan stationed in Bangladesh surrendered. This surrender remains to date the largest capitulation of soldiers since the Second World War.

Atrocities and Resistance

Both rural and urban areas across East Pakistan endured extensive military operations and relentless air strikes, all aimed at suppressing the tide of civil disobedience that had surged following the 1970 election stalemate. The Pakistan Army, with the backing of various Islamist groups, actively created radical religious militias—the Razakars, Al-Badr, and Al-Shams—to assist in their brutal raids on the local populace. Urdu-speaking Biharis, an ethnic minority residing in Bangladesh, also lent their support to the Pakistani military. Members of the Pakistani military and these supporting militias engaged in unspeakable acts of mass murder, forced deportation, and genocidal rape. The capital, Dacca (now Dhaka), became the scene of numerous massacres, including the initial onslaught of Operation Searchlight and the horrific Dhaka University massacre. The scale of the humanitarian crisis was immense: an estimated 10 million Bengali refugees fled to neighboring India, while a staggering 30 million people were internally displaced within East Pakistan. Sectarian violence erupted between Bengalis and Urdu-speaking immigrants. Today, a prevailing academic consensus confirms that the atrocities committed by the Pakistani military constituted a genocide.

The Birth of a Nation: Bengali Valor and International Support

Amidst the chaos and terror, the Bangladeshi Declaration of Independence was courageously broadcast from Chittagong by members of the Mukti Bahini—the national liberation army formed by patriotic Bengali military personnel, paramilitaries, and civilians. Key units like the East Bengal Regiment and the East Pakistan Rifles played a crucial role in the fierce resistance. Led by General M. A. G. Osmani and eleven sector commanders, the Bangladesh Forces waged an extensive guerrilla war against the formidable Pakistani military. They achieved remarkable success, liberating numerous towns and cities in the initial months of the conflict. While the Pakistan Army regained some momentum during the monsoon season, Bengali guerrillas continued their widespread sabotage efforts, including "Operation Jackpot" against the Pakistan Navy. A nascent Bangladesh Air Force even flew sorties against Pakistani military bases. By November, the determined Bangladesh forces had managed to restrict the Pakistani military to its barracks during the night, effectively securing control of most parts of the countryside.

On April 17, 1971, the Provisional Government of Bangladesh was formally established in Mujibnagar, subsequently moving to Calcutta (now Kolkata) as a government in exile. Bengali members of the Pakistani civil, military, and diplomatic corps defected en masse to support the newly formed Bangladeshi provisional government. Thousands of Bengali families were interned in West Pakistan, with many bravely escaping to Afghanistan. Bengali cultural activists operated the clandestine "Free Bengal Radio Station," broadcasting messages of hope and resistance. The plight of millions of war-ravaged Bengali civilians caused worldwide outrage and alarm. India, under the astute leadership of Prime Minister Indira Gandhi, provided substantial diplomatic, economic, and military support to the Bangladeshi nationalists. In a pioneering act of solidarity, British, Indian, and American musicians organized the world's first benefit concert in New York City to support the Bangladeshi people. In the United States, Senator Ted Kennedy led a congressional campaign advocating for an end to Pakistani military persecution, while remarkably, U.S. diplomats in East Pakistan strongly dissented with the Nixon administration's close ties to the Pakistani military dictator, Yahya Khan.

India's Intervention and the War's Conclusion

The war escalated dramatically on December 3, 1971, when India formally joined the conflict after Pakistan launched preemptive air strikes on North India. The subsequent Indo-Pakistani War saw engagements on two distinct war fronts. With air supremacy decisively achieved in the eastern theatre and the rapid, coordinated advance of the Allied Forces—comprising the Mukti Bahini and the Indian military—Pakistan's forces in Dacca were ultimately compelled to surrender on December 16, 1971, marking the end of the brutal conflict.

Aftermath and Geopolitical Impact

The Bangladesh Liberation War irrevocably altered the geopolitical landscape of South Asia, leading to the emergence of Bangladesh as a sovereign nation, which rapidly became the seventh-most populous country in the world. Due to complex regional alliances, the war was also a significant episode in the broader Cold War tensions, involving global superpowers such as the United States, the Soviet Union, and the People's Republic of China. By 1972, the majority of member states in the United Nations had recognized Bangladesh as an independent and sovereign nation, solidifying its place on the world stage.
