About the Mountbatten Plan, Partition and Independence (1947)
The Mountbatten Plan, also called the 3rd June Plan, was the final blueprint by which the British transferred power in India in 1947. It led to the partition of British India into two independent dominions – India and Pakistan – and to the Indian Independence Act, 1947. The events of this year ended nearly two centuries of British rule, drew the Radcliffe Line, triggered one of the largest migrations in human history, and began the integration of over 560 princely states into the Indian Union.
Introduction and Background: Why Partition Happened
The Second World War ended in 1945, and Britain was exhausted. The Indian National Army (INA) trials and the Royal Indian Navy (RIN) Mutiny of February 1946 shook British confidence in the loyalty of the Indian armed forces. In March 1946 the Cabinet Mission, consisting of Pethick-Lawrence, Stafford Cripps and A. V. Alexander, arrived to discuss the transfer of power but failed to produce a settlement acceptable to both the Congress and the Muslim League. The Muslim League observed Direct Action Day on 16 August 1946, which led to the terrible Great Calcutta Killings, followed by communal violence in Noakhali and Bihar. On 20 February 1947, Prime Minister Clement Attlee declared in the House of Commons that the British would leave India by June 1948 at the latest, and on 24 March 1947 Lord Mountbatten arrived as the last Viceroy of India.
Key Developments
Mountbatten quickly concluded that a united India was no longer possible because the Congress and the Muslim League could not agree on the future of the Two Nation Theory and the demand for Pakistan. The Lahore Resolution of 23 March 1940 had already demanded independent states for Muslim-majority areas. Mountbatten therefore prepared a plan for the transfer of power to two successor states, which the British government approved and announced on 3 June 1947.
Under the Mountbatten Plan, the Muslim-majority provinces could join Pakistan and the Hindu-majority provinces could remain in India. The Congress accepted the plan, and its main leaders Jawaharlal Nehru and Sardar Vallabhbhai Patel agreed to it because they feared worse chaos and wanted a strong, united India. The Muslim League accepted it with Muhammad Ali Jinnah giving his assent. The plan was given legal shape by the Indian Independence Act, passed by the British Parliament on 18 July 1947, which ended British sovereignty over India with effect from 15 August 1947.
The Boundary Commission, headed by Sir Cyril Radcliffe, drew the Radcliffe Line between India and Pakistan, dividing Punjab and Bengal. The transfer of power was accompanied by terrible violence and the migration of about 10 to 15 million people across the new borders. On 15 August 1947 India became an independent dominion; Lord Mountbatten became its first Governor-General, and Jawaharlal Nehru became the first Prime Minister. On the night of 14 August 1947, Nehru delivered the famous “Tryst with Destiny” speech. Pakistan celebrated its independence on 14 August 1947, and Jinnah became its first Governor-General. Later, C. Rajagopalachari became the first Indian Governor-General in 1948. Mahatma Gandhi, who had opposed partition, was assassinated on 30 January 1948 by Nathuram Godse in Delhi.
The princely states were integrated into the Indian Union under the leadership of the Minister of States, Sardar Patel, who was called the “Iron Man of India”. States signed the Instrument of Accession. Junagadh was brought in through diplomacy and a plebiscite, Hyderabad was integrated in 1948 by the police action known as Operation Polo, and Kashmir signed the Instrument of Accession on 26 October 1947 under Maharaja Hari Singh after a Standstill Agreement failed. In the meantime, the Constituent Assembly, which first met in December 1946, adopted the Objective Resolution moved by Jawaharlal Nehru, adopted the Constitution of India on 26 November 1949, and enforced it on 26 January 1950, making India a sovereign Republic.
