1971 — Liberation War

1947

Partition and Eastern Bengal

In 1947, British India was divided into India and Pakistan, and Bengal itself was split into West Bengal and East Bengal. The chapter is not only about constitutional division: the delayed Radcliffe boundary, minority insecurity, refugee movement, and administrative rupture reshaped everyday life and set the stage for later struggles over language, autonomy, and state legitimacy in East Bengal.

1969

Mass Uprising

The 1969 Mass Uprising in East Pakistan brought together students, workers, opposition parties, and ordinary citizens against prolonged military-backed authoritarianism. It accelerated the collapse of the Ayub regime, widened the demand for democratic rights and regional autonomy, and prepared the political ground for the decisive elections of 1970 and the liberation struggle that followed.

1970

Bhola Cyclone and the 1970 Election

In late 1970, East Pakistan was shaken first by the catastrophic Bhola cyclone of 12 November and then by Pakistan's first general election under universal adult franchise on 7 December. The cyclone exposed the scale of administrative neglect, relief failure, and delta vulnerability, while the election gave Sheikh Mujibur Rahman's Awami League an overwhelming democratic mandate. Together, ecological catastrophe and the denied transfer of power turned autonomy politics into an immediate constitutional crisis on the eve of the Liberation War.

March-April 1971

Declaration and Proclamation of Independence

Between late March and April 1971, Bangladesh's independence struggle moved from mass resistance to an explicit claim of statehood. The declaration of independence issued in Sheikh Mujibur Rahman's name after the 25 March crackdown, followed by the formal Proclamation of Independence adopted by the provisional leadership, gave the war a constitutional language, a legal rationale, and an organizing political center.

1972

State Formation and the 1972 Constitution

In 1972, Bangladesh moved from wartime victory to the difficult work of state formation. Sheikh Mujibur Rahman returned in January to lead the new government, the Constituent Assembly began work in April, and the Constitution of the People's Republic of Bangladesh was adopted on 4 November before taking effect on 16 December. The year linked liberation to institution-building through parliamentary government, fundamental rights, and the four state principles of nationalism, socialism, democracy, and secularism.

1975

BAKSAL: Formation and Collapse

In 1975, Bangladesh entered a decisive turning point: the transition toward BAKSAL, escalating political centralization, the assassination of Sheikh Mujibur Rahman on 15 August, and the jail killings of 3 November. These events reshaped the state, party politics, and military-civil relations for decades.

2010

International Crimes Tribunal Begins

In 2010, Bangladesh operationalized the International Crimes Tribunal process to prosecute 1971-related crimes under the 1973 law. What had long remained an unresolved justice demand now moved into courts, reopening questions of accountability, public memory, due process, and political legitimacy that soon spilled into mass mobilization and counter-mobilization.

2013

Shahbag Movement

In early 2013, mass gatherings at Shahbag in Dhaka called for stronger accountability for war crimes linked to 1971. Students, bloggers, cultural activists, and citizens transformed the square into a sustained protest space, turning memory politics and justice debates into a central national question.

1952

Language Movement

The Language Movement grew out of the post-1947 struggle over representation, when demands for Bangla in the Constituent Assembly, education, administration, and public life collided with the Pakistani state's Urdu-only policy. The movement reached its decisive phase in February 1952, when students and activists defied Section 144 and police opened fire, turning language into the moral center of Bengali political identity.
