Britain’s Cabinet Mission issued its statement proposing a united but highly decentralized Indian federation, with provinces grouped into sections and the center limited mainly to defense, foreign affairs, and communications—an attempted compromise between Congress and the Muslim League as independence neared.
Jawaharlal Nehru publicly stated that provinces would not be compelled to remain in the Cabinet Mission’s proposed groupings, undermining Muslim League confidence that the plan could protect Muslim-majority regions within a united India.
The All-India Muslim League rescinded its prior approval of the Cabinet Mission Plan, escalating the constitutional deadlock over the nature of the post-British state and strengthening the push toward partition.
The Muslim League observed Direct Action Day to press for Pakistan; protests and a general strike escalated into severe communal हिंसा, especially in Calcutta, marking a pivotal turning point toward partition.
An interim government headed by Jawaharlal Nehru began functioning to manage the transition toward independence, though communal tensions and political rivalry continued to intensify.
British Prime Minister Clement Attlee told the House of Commons that Britain would transfer power in India by June 1948 and confirmed Viscount Mountbatten’s appointment as the last viceroy to oversee the process.
Viscount Mountbatten arrived in India to take charge of the final transfer-of-power negotiations amid worsening communal violence and the accelerating push for partition.
Mountbatten publicly outlined the plan to partition British India and set mid-August 1947 for independence, including provisions for dividing Punjab and Bengal and holding referendums in disputed areas.
The Bengal Legislative Assembly held the decisive votes under the 3 June Plan framework, leading to the province’s partition into West Bengal (India) and East Bengal (Pakistan).
At a loya jirga in Bannu, Khudai Khidmatgar leaders and allied figures demanded that Pashtuns be given an option beyond India-or-Pakistan—such as an independent “Pashtunistan”—a demand the British did not accept.
A Boundary Commission was set up (with Sir Cyril Radcliffe as chair) to draw the new borders in Punjab and Bengal—work carried out under extreme time pressure immediately before independence.
Voters in Sylhet district (Assam) chose to join East Bengal, aligning the district with Pakistan’s eastern wing (with later boundary adjustments affecting areas such as Karimganj).
The UK Parliament’s Indian Independence Act became law, providing for the creation of the Dominions of India and Pakistan and authorizing the partition of Bengal and Punjab, effective mid-August 1947.
A province-wide referendum in the North-West Frontier Province resulted in an overwhelming vote for accession to Pakistan, despite a boycott by key anti-partition leaders and movements.
Pakistan’s Constituent Assembly met in Karachi on the eve of independence; Muhammad Ali Jinnah was elected its president, establishing the core institutional framework for the new dominion’s governance.
In a major address to the Constituent Assembly, Jinnah emphasized rule of law, equal citizenship, and religious freedom as guiding principles for the new state’s political order.
Under the Indian Independence Act framework, the Dominion of Pakistan came into being, with independence commemorated on 14 August in Pakistan (15 August in India).
The Radcliffe Line (the Boundary Commission’s final award) was published two days after independence, fixing the borders of India and Pakistan in Punjab and Bengal and intensifying displacement and conflict along the new frontier.
