The Partition of India 1947 was the division of British India into the two independent dominions of India and Pakistan on 15 August 1947. Under the Mountbatten Plan of 3 June 1947 and the Indian Independence Act, the provinces of Punjab and Bengal were split along the Radcliffe Line, drawn on the basis of religious majority. The result was one of the largest and most violent migrations in human history, a vast refugee crisis and a contested division of assets, and these wounds shaped the new nation and its relations with Pakistan from its very first day.

Introduction: Freedom and Partition Together

Why Partition Is the Wound at the Heart of Nation-Building

Why this matters: independence and Partition came on the same day, and the new nation was born amid one of the great human catastrophes of the century. The way the subcontinent was divided shaped the refugee crisis, the communal wounds and the rivalry with Pakistan that nation-building would have to manage from the start.

What is the significance of Partition: it set the terms of everything that followed. The division produced a vast refugee movement, a contested boundary, a divided army and treasury, and the unfinished question of Kashmir, all of which the new state inherited along with its freedom, as the map and the sections below set out.

The Road to Partition: From the Breakdown of 1946 to the June 3 Plan

From Direct Action Day to the Plan of June 1947

What is the significance of the road to partition: it shows that partition was the end of a rapid, contested breakdown rather than a settled choice. Direct Action Day on 16 August 1946 and the Great Calcutta Killings hardened communal lines, and the Cabinet Mission plan for a united federal India collapsed over the question of grouping the provinces.

Distinguishing the final steps: Lord Mountbatten, the last Viceroy, arrived in March 1947 with instructions to transfer power quickly. His June 3 Plan set out partition into two dominions; the Congress, then led by its president J. B. Kripalani, accepted it as the only way out of the deadlock, and it was given legal form by the Indian Independence Act.

The Mountbatten Plan and the Indian Independence Act 1947

The June 3 Plan and the Legal Act That Followed

What is the significance of the plan and the Act: they are two distinct things often confused. The Mountbatten Plan of 3 June 1947 was the political settlement that announced partition; the Indian Independence Act, passed by the British Parliament, was the legal instrument that actually created the two dominions on 15 August 1947.

Distinguishing the provinces' choice: the plan let the legislatures of Punjab and Bengal vote on partition, held referenda in Sylhet and the North-West Frontier Province, and lapsed British paramountcy over the princely states, leaving them to accede, the subject of the next part. The Act ended British rule and made each dominion sovereign.

The Radcliffe Boundary Commissions and the India-Pakistan Border

Two Commissions, One Chairman, a Line Drawn in Weeks

What is the significance of the Radcliffe Line: it was the actual border that cut through two provinces. Two Boundary Commissions, one for Punjab and one for Bengal, were chaired by the British lawyer Cyril Radcliffe, who had never before visited the land, and were tasked to divide contiguous majority areas of each community between the two dominions.

Distinguishing the controversy: each commission had two Congress and two Muslim League nominees, so Radcliffe's casting decisions were decisive. The award was withheld until 17 August 1947, after independence, and districts such as Gurdaspur remained bitterly disputed, as the commissions below set out.

The armed forces Units and officers divided between the two dominions A divided army at the very moment of independence
Assets and treasury Cash balances and stores apportioned between the dominions A disputed division, including the cash-balance question
The administration Services, records and railways split A new state machinery had to be built at once

Communal Violence and the Largest Mass Migration in History

The Human Catastrophe of 1947

Observable outcomes of the line were immediate and terrible. As the boundary became known, Hindus and Sikhs fled eastward and Muslims fled westward and eastward, in one of the largest and swiftest mass migrations ever recorded. The Punjab Boundary Force could not contain the killing, and millions were uprooted within weeks.

Distinguishing the human cost: the violence brought massacres, the abduction of women on a mass scale and the destruction of whole communities. The casualties and the numbers displaced are estimated very differently by different sources, so they are best understood as a catastrophe of millions rather than a single agreed figure.

The Refugee Crisis and the State Response to Rehabilitation

Managing a Catastrophe While Building a State

What is the significance of rehabilitation: it was the first great test of the new state's capacity. A Ministry of Rehabilitation was created to resettle the refugees in camps, new colonies and expanded towns, a task that reshaped cities such as Delhi and the economy of the north-west and the east for decades.

Distinguishing the women's question: an inter-dominion agreement set up operations to recover abducted women on both sides, a fraught and contested process. The refugee crisis below shows how nation-building had to begin by managing a humanitarian emergency, not from a clean slate.

Dividing a State and the Enduring Legacies of Partition

From the Division of Assets to a Lasting Inheritance

Observable outcomes of partition reached into the machinery of the state. The armed forces, the treasury and the services were divided between the two dominions, and the cash-balance dispute strained relations from the start. The new state had to build its administration even as it absorbed millions of refugees, as the timeline below traces.

Contemporary linkages run from 1947 straight into the present. Partition left the seeds of the Kashmir dispute and a permanent rivalry with Pakistan, hardened communalism as a force in politics, and shaped the integration of the states that the next part takes up. The points below gather the threads.
