In short: In 1947, Sir Cyril Radcliffe was tasked with partitioning 175,000 square miles of territory and 88 million people in just five weeks. With no local knowledge and a desperate British government pushing for a swift exit, his final, secret line triggered one of the largest migrations in human history.

The Radcliffe Line was the result of the Indian Independence Act of 1947, which mandated the end of British rule and the creation of two sovereign dominions: India and Pakistan. The challenge was to divide the provinces of Punjab and Bengal, where religious demographics were too intertwined for a clean separation. While Pakistan was envisioned as a Muslim homeland, these provinces lacked overwhelming majorities, forcing a complex territorial split that cut through irrigation systems, rail lines, and individual landholdings.

Sir Cyril Radcliffe, a lawyer with no prior experience in India, was appointed to chair the boundary commissions. He was given only five weeks to complete the work, a timeframe he objected to but ultimately accepted under pressure from Viceroy Lord Mountbatten. Radcliffe worked in isolation, deliberately avoiding outside experts or United Nations involvement to maintain the appearance of British autonomy. His commission members, representing the Indian National Congress and the Muslim League, were so deeply divided that they could barely communicate, leaving the final, difficult decisions entirely to Radcliffe.

The process was shrouded in secrecy, with the final awards ready by mid-August but withheld from publication until two days after independence. This delay, combined with the lack of administrative preparation, left the new nations to manage the fallout. The border was not just a line on a map; it became a source of lasting conflict, sparking multiple wars and mass displacement. Radcliffe himself departed India on Independence Day, having destroyed his personal papers, leaving behind a legacy of partition that continues to shape the geopolitical reality of South Asia.

The implementation was marred by political maneuvering and accusations of bias. Historians note that the final award for the Ferozepur district was likely altered to favor India, ensuring control over vital canal headworks and military depots. Meanwhile, communities like the Sikhs found themselves split, and others, such as the Buddhist tribes in the Chittagong Hill Tracts, were left without representation or information. The haste and lack of local consultation ensured that the partition was not a clean administrative act, but a profound tragedy.
