1947 — Partition and Eastern Bengal

1940

Lahore Resolution

In March 1940, the All-India Muslim League adopted the Lahore Resolution at its Lahore session, and A. K. Fazlul Huq of Bengal formally moved the resolution. The text called for Muslim-majority areas in the northwestern and eastern zones of British India to be grouped into 'independent states' with autonomous and sovereign constituent units. Although it did not mention Pakistan by name, it became a major political turning point in constitutional politics.

1946

Direct Action Day and the Great Calcutta Killing

On 16 August 1946, the All-India Muslim League observed Direct Action Day to press its demand for Pakistan after the collapse of Cabinet Mission negotiations. In Bengal, where Huseyn Shaheed Suhrawardy led the provincial ministry, the hartal and mass rally in Calcutta escalated into large-scale communal killings. The violence in Calcutta, followed by major communal violence in places including Noakhali and Bihar later in 1946, marked a severe breakdown of coexistence in late colonial India and hardened pathways toward partition.

1943

Bengal Famine

The Bengal Famine of 1943 caused catastrophic hunger and death across Bengal. Wartime disruption, rice-market inflation, transport strain, relief failure, and policy breakdown under British colonial administration intensified the crisis, devastating rural households, laboring families, and urban poor communities alike.

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.

1948

Language Question Becomes a Mass Political Issue

In 1948, language rights became a central political question in East Bengal as students and intellectual groups protested attempts to privilege Urdu alone. Strikes, memoranda, and street mobilization during this period laid the foundation for the later 1952 martyrdom-centered phase of the Language Movement.

1971

Liberation War

The Liberation War of 1971 grew out of the denied majority verdict of the 1970 election, the March non-cooperation movement, and the Pakistan Army's 25 March crackdown. What followed was not a single battlefield episode but a combined political, military, and humanitarian rupture: a provisional government, sector-based armed resistance, mass displacement into India, and finally the defeat of Pakistani forces in December and the birth of Bangladesh.

1906

All-India Muslim League Founded in Dhaka

In December 1906, the All-India Muslim League was founded at Dhaka during the Muhammadan Educational Conference. The formation of the League created a new all-India political platform that sought Muslim representation within colonial constitutional politics and would later play a central role in partition-era negotiations.

1911

Annulment of Bengal Partition

In 1911, the British government annulled the 1905 partition of Bengal and reunited Bengal as a single province. The reversal followed years of protest, boycott, and political mobilization, while also introducing a new imperial administrative order with the transfer of the capital from Calcutta to Delhi.
