On August 14–15, 1947, British India became independent as two nations, India and Pakistan, amid mass migration and deadly communal violence.
See it on the History map →What happened
Weakened by World War II and facing Indian demands, Britain decided to leave quickly. The Congress party wanted a united India; the Muslim League, led by Muhammad Ali Jinnah, demanded a Muslim homeland. A British lawyer, Cyril Radcliffe, drew the borders in about five weeks, splitting Punjab and Bengal. Some 10–20 million people crossed the new borders, and roughly 200,000 to 2 million were killed in communal violence; estimates vary. Kashmir's disputed status sparked war within months.
Why it matters
India became the world's largest democracy and its freedom inspired colonies everywhere, while Partition left the India–Pakistan rivalry, the Kashmir dispute, and eventually two nuclear-armed neighbors.
How we know
The Indian Independence Act of 1947, British and Indian government records, Radcliffe's boundary awards, newspapers, and survivors' oral histories gathered by groups such as the 1947 Partition Archive.
Still debated
Who bears most blame for Partition, British haste, Jinnah, or Congress leaders like Nehru, and the true death toll remain contested.

▸British Raj in India was ended by Indian independence and PartitionWell documented
The connection
British rule over India grew from East India Company conquests in the 1700s to direct Crown rule from 1858. The independence movement grew from the 1885 founding of the Indian National Congress. After World War II, an exhausted Britain, facing mass protest and a 1946 naval mutiny, handed power to India and Pakistan in August 1947.
When and how
Delhi and London, 1945–47; Prime Minister Clement Attlee, the last viceroy Lord Mountbatten, and Indian leaders Nehru, Jinnah and Gandhi shaped the handover.
How we know
The Indian Independence Act passed by Parliament in July 1947, British cabinet papers, and the official Transfer of Power documents published later.
Debates and open questions
Whether Britain left mainly because of Indian pressure or its own postwar weakness is debated, as is whether the rushed timetable worsened the Partition violence.
▸Indian independence and Partition led the wave of Decolonization: the end of empiresMostly agreed
The connection
India was the largest colony to win freedom, and its success showed others that empires could be ended. Prime Minister Nehru championed anti-colonialism at the UN and at the 1955 Bandung Conference of Asian and African states. Within two decades most of Asia and Africa had followed.
When and how
From 1947; the Bandung Conference in Indonesia, April 1955, gathered 29 Asian and African countries; leaders such as Ghana's Kwame Nkrumah cited India's example.
How sure are we?
UN records of India's anti-colonial campaigns, Bandung documents, and African and Asian leaders' own statements crediting India's example.
Debates and open questions
Some colonies, such as the Philippines (1946), became independent earlier, and every movement had local roots; how much India's example drove the rest is debated.
▸Mahatma Gandhi led the struggle that ended in Indian independence and PartitionWell documented
The connection
Gandhi turned the Indian National Congress from an elite debating club into a mass movement of millions, using boycotts, strikes and civil disobedience. Campaigns in 1920–22, 1930–31 (the Salt March) and 1942 ('Quit India') made British rule costly and morally exposed. But he opposed Partition and was sidelined in the final negotiations.
When and how
Across India, 1920–1947, alongside leaders such as Jawaharlal Nehru, Vallabhbhai Patel and Muhammad Ali Jinnah; on independence day Gandhi was in Calcutta trying to stop riots.
How we know
Arrest records, British intelligence and cabinet files, newspapers and Gandhi's own writings document his leadership; British officials repeatedly named him their chief challenge.
Debates and open questions
Historians debate how much his nonviolent campaigns, versus World War II, Britain's finances and the 1946 naval mutiny, decided the timing of independence.
