Partition of India
1947 Partition of British India

The partition of India in 1947 was the division of British India into two independent dominion states, the Union of India and Dominion of Pakistan. The Union of India is today the Republic of India, and the Dominion of Pakistan is the Islamic Republic of Pakistan and the People's Republic of Bangladesh. The partition involved the division of two provinces, Bengal and the Punjab, based on district-wide non-Muslim (mostly Hindu and Sikh) or Muslim majorities. It also involved the division of the British Indian Army, the Royal Indian Navy, the Indian Civil Service, the railways, and the central treasury, between the two new dominions. The partition was set forth in the Indian Independence Act 1947 and resulted in the end of the British Raj, or Crown rule in India. The two self-governing countries of India and Pakistan legally came into existence at midnight on 14–15 August 1947.
With the partition of British India and withdrawal of the British from the Indian subcontinent, the Indian Independence Act provided that the princely states were released from their subsidiary alliances and other obligations to the British, while the British withdrew from their obligations to the states, leaving the rulers to decide whether to accede to India or Pakistan or to remain independent outside both. Sardar Patel said in a speech in January 1948, "On the lapse of Paramountcy, every Indian State became a separate independent entity." The political integration of the princely states into the two new dominions was begun by many accessions in August 1947, but mostly it followed on later. Critically, the rulers of the states of Hyderabad, Jammu and Kashmir, and others, chose independence.
The partition displaced between 12 and 20 million people along religious lines, creating overwhelming refugee crises associated with the mass migration and population transfer that occurred across the newly constituted dominions; there was large-scale violence, with disputed estimates of the loss of life before, at the time of, or following the partition.

Why this record matters
“Partition of India” is worth following because a concise public description often conceals a longer documentary argument. Here, Partition, India and British provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q129053. The Library of Congress control number is sh97003291. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947 and 1948.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
