Mountbatten Plan

The Mountbatten Plan, also known as the June 3 Plan, was the final British proposal for the transfer of power in India, announced on June 3, 1947. Lord Louis Mountbatten, the last Viceroy, arrived on March 24, 1947, with a mandate to expedite the process.

Recognizing the deep communal divide and the failure of previous proposals like the Cabinet Mission Plan, Mountbatten concluded that partition was inevitable. The plan's core provisions included the division of British India into two independent Dominions, India and Pakistan, effective August 15, 1947.

It mandated the partition of Bengal and Punjab based on contiguous majority areas, with referendums in NWFP and Sylhet. Crucially, it declared the lapse of British paramountcy over the princely states, allowing them to accede to either Dominion or remain independent, though practical realities favored accession.

The timeline for independence was dramatically accelerated from June 1948 to August 1947, a decision driven by Mountbatten's assessment of escalating communal violence and administrative challenges. The plan led to the Indian Independence Act 1947, which legally formalized the creation of India and Pakistan.

However, the hasty implementation, particularly the boundary demarcation by the Radcliffe Commission, resulted in unprecedented communal violence, mass migration, and a severe refugee crisis, leaving a lasting impact on the subcontinent's geopolitics and social fabric.

For UPSC, this plan represents a critical juncture, shaping India's constitutional journey and its post-independence challenges.
