Mountbatten Plan 1947 (June 3 Plan) was the British blueprint for partitioning British India into two independent dominions — India and Pakistan. Announced on 3 June 1947 by Lord Mountbatten, the last Viceroy of India, it advanced independence to August 1947 and established Radcliffe Boundary Commissions to divide Punjab and Bengal.

Background: Why Was the Mountbatten Plan Necessary?

By early 1947, British India was convulsed by communal violence. The failure of the Cabinet Mission Plan (1946) to forge a power-sharing arrangement between the Indian National Congress and the All-India Muslim League had made partition appear unavoidable. In February 1947, Prime Minister Clement Attlee announced that Britain would transfer power no later than June 1948 and appointed Lord Louis Mountbatten as the last Viceroy to oversee the process.

Mountbatten arrived in India in March 1947 and quickly concluded that the situation was too volatile to delay. Through intense negotiations with Jawaharlal Nehru, Sardar Vallabhbhai Patel, and Muhammad Ali Jinnah, he drafted a plan that accepted the Muslim League's demand for a separate Muslim homeland while preserving as much administrative order as possible during the transition.

What Were the Key Provisions of the Mountbatten Plan?

The plan was formally announced on 3 June 1947. Its principal provisions were:

  1. Partition into two dominions: British India would be divided into two independent dominions — India and Pakistan. Both would remain within the British Commonwealth as self-governing dominions during the transition period.
  2. Partition of Punjab and Bengal: Punjab and Bengal, which contained mixed Hindu and Muslim populations, would themselves be partitioned. Boundary Commissions headed by Sir Cyril Radcliffe would draw the new international borders.
  3. Legislative Assembly votes: The Legislative Assemblies of Punjab and Bengal would meet in two groups — Muslim majority and non-Muslim majority districts — to vote on whether to seek partition of their respective provinces.
  4. Princely states given a choice: The roughly 565 princely states that held treaty relations with the British Crown were freed from those obligations. They could accede to India, accede to Pakistan, or theoretically remain independent.
  5. Separate Constituent Assemblies: Distinct Constituent Assemblies would be established for India and Pakistan, each empowered to frame its own constitution free of British oversight.
  6. Advancement of independence date: The original deadline of June 1948 was dramatically brought forward. India would become independent at midnight on 14–15 August 1947; Pakistan on 14 August 1947.

Who Was Sir Cyril Radcliffe and What Did the Radcliffe Award Decide?

Sir Cyril Radcliffe was a distinguished British lawyer who had never visited India before his appointment. He was tasked with chairing two Boundary Commissions — one for Punjab and one for Bengal — and was given only five weeks to complete work that would redraw the map of the subcontinent for generations.

The Radcliffe Award was published on 17 August 1947 — two days after independence had already been proclaimed. This timing was deliberate: Mountbatten feared that releasing the boundaries before independence would inflame violence and disrupt the transfer of power ceremonies. The consequences, however, were catastrophic.

Province India's Share Pakistan's Share
Punjab East Punjab (Amritsar, Jullundur) West Punjab (Lahore, Rawalpindi)
Bengal West Bengal (Calcutta) East Bengal / East Pakistan (Dhaka)

The partition of Punjab proved especially catastrophic. Approximately one million people were killed and fourteen million displaced in one of the largest forced migrations in recorded history. Trains carrying refugees were ambushed; entire villages were massacred. The Bengal partition also caused immense displacement, though on a somewhat smaller scale than Punjab.

How Did Indian Leaders Respond to the Plan?

The response of Indian political leaders was varied and often anguished:

  • Jawaharlal Nehru and Sardar Patel accepted the plan pragmatically. They believed that a united India governed under a weak federal centre — as envisaged by the Cabinet Mission — would be ungovernable. A clean partition, however painful, offered a better foundation for a stable Indian state.
  • Muhammad Ali Jinnah and the All-India Muslim League accepted the plan, though Jinnah privately described the resulting Pakistan as a "moth-eaten" state — smaller than the League had originally envisioned, stripped of the eastern districts of Punjab and Bengal.
  • Mahatma Gandhi was deeply opposed to partition and refused to attend the independence celebrations on 15 August 1947. He saw the division of the subcontinent as a failure of the freedom struggle's founding ideal of Hindu-Muslim unity. Once the Congress Working Committee accepted the plan, however, Gandhi did not mount a public campaign against it.

What Was the Historical Significance of the Mountbatten Plan?

The Mountbatten Plan was the formal legal decision that ended British colonial rule in the Indian subcontinent and created two sovereign nations. Its significance is profound across multiple dimensions:

  • Acceleration of independence: By compressing the timeline from June 1948 to August 1947, the plan forced hasty division of the Indian Army, the civil services, and financial assets, contributing to the administrative chaos that accompanied Partition.
  • Creation of Pakistan: The plan gave legal expression to the two-nation theory, permanently dividing the subcontinent on religious lines — a decision that continues to shape South Asian geopolitics.
  • Humanitarian catastrophe: The violence in Punjab and Bengal produced a trauma that shaped the identities, literature, and political cultures of both India and Pakistan for decades afterward.
  • Integration of princely states: By releasing princely states from Crown obligations, the plan set the stage for Sardar Patel's integration campaign, which ultimately unified more than 500 princely states into the Indian Union.
  • Dominion status as a bridge: Both nations became Dominions under the Crown initially, allowing a smooth constitutional transition before each adopted its own republican constitution — India in 1950, Pakistan in 1956.

Frequently Asked Questions

What is the Mountbatten Plan of 1947?

The Mountbatten Plan, announced on 3 June 1947, was the British government's blueprint for partitioning British India into two independent dominions — India and Pakistan. It outlined the division of Punjab and Bengal, the role of the Radcliffe Boundary Commissions, freedom for princely states to choose their accession, and the advancement of independence to August 1947.

Why is the Mountbatten Plan also called the June 3 Plan?

The plan is called the June 3 Plan because it was formally announced by Lord Mountbatten, the last Viceroy of India, on 3 June 1947. The date marks the formal British decision to accept partition as the mechanism for transferring power to Indian hands.

Who was Cyril Radcliffe and why is his role significant in the Mountbatten Plan?

Sir Cyril Radcliffe was a British lawyer appointed to chair the Boundary Commissions for Punjab and Bengal under the Mountbatten Plan. Having never visited India before, he drew the borders of the two new nations in just five weeks. The Radcliffe Award, published on 17 August 1947 — two days after independence — divided Punjab and Bengal and triggered massive displacement and communal violence across both provinces.

Did Gandhi support the Mountbatten Plan?

No. Mahatma Gandhi was deeply opposed to the partition of India and refused to participate in the independence celebrations on 15 August 1947. He saw partition as a betrayal of the freedom movement's ideals of communal unity. However, once the Congress leadership accepted the plan, Gandhi did not actively campaign against it.

What happened to the princely states under the Mountbatten Plan?

Under the Mountbatten Plan, the approximately 565 princely states were released from their treaty obligations with the British Crown and given the choice to accede to India, accede to Pakistan, or theoretically remain independent. In practice, nearly all acceded to India through the integration drive led by Sardar Vallabhbhai Patel and V. P. Menon, except for initial holdouts such as Hyderabad, Junagadh, and Jammu and Kashmir.
