Prelims & Mains: Mountbatten Plan, Indian Independence Act 1947, Partition of India, Boundary Commission 

By early 1947, British India was witnessing unprecedented political deadlock and communal violence. The failure of the Cabinet Mission Plan (1946), the Muslim League’s demand for Pakistan, and widespread riots convinced British policymakers that maintaining a united India had become increasingly difficult.

In February 1947, British Prime Minister Clement Attlee announced that power would be transferred to Indian hands by June 1948.

To oversee the transition, Lord Louis Mountbatten arrived in India on 22 March 1947 as the last Viceroy.

What was the Mountbatten Plan?

Announced on 3 June 1947, the Mountbatten Plan accepted the partition of British India and outlined the mechanism for creating two sovereign dominions: India and Pakistan.

Major Provisions:

1. Partition of British India: British India would be divided into India and Pakistan. Both would become self-governing dominions under the British Commonwealth.

2. Division of Punjab and Bengal: The Legislative Assemblies of Punjab and Bengal were to vote separately on whether: (i) the provinces should remain united. (ii) They should be partitioned between India and Pakistan. Both provinces ultimately voted for partition.

3. Referendum in NWFP: A referendum was to be conducted in the North-West Frontier Province (NWFP) to determine whether it would join India or Pakistan. The province voted in favour of Pakistan.

4. Referendum in Sylhet: The Muslim-majority district of Sylhet in Assam was given the option through a referendum to join East Bengal (Pakistan). The majority voted to join Pakistan.

5. Sindh Assembly Decision: The Sindh Legislative Assembly was empowered to decide whether Sindh would join Pakistan. It voted in favour of Pakistan.

6. Boundary Commission: A Boundary Commission headed by Sir Cyril Radcliffe was constituted to demarcate the borders of Punjab and Bengal. This led to the Radcliffe Line, announced on 17 August 1947.

7. Princely States: The approximately 565 princely states were advised to accede either to India or Pakistan, taking into account: Geographical contiguity & Administrative convenience. The option of complete independence was not formally encouraged by the British.

8. Early Transfer of Power: The transfer of power was advanced from June 1948 to 15 August 1947, leaving only about ten weeks for implementation.

Why did Congress accept Partition?
