The man who drew the India-Pakistan border

In 1947, British lawyer Sir Cyril Radcliffe was tasked with drawing new international borders in Punjab and Bengal following the partition of British India. With no prior experience in the region, Radcliffe was given only five weeks to complete the task, working under immense pressure as Britain was ending its colonial rule. The boundary decisions, known as the Radcliffe Line, divided the provinces of Punjab and Bengal, causing one of the largest mass migrations in history.

The Radcliffe Line was drawn to separate the Hindu and Muslim populations, while also considering administrative arrangements, communications, geographical features, and economic interests. However, the boundaries were announced after independence, adding to the confusion and uncertainty surrounding the partition. The line cut through villages, farmland, railways, and trading routes, impacting the lives of millions who were left uncertain about their future homes and communities.

The most devastating consequence of the partition was the massive movement of people, with millions of Hindus, Muslims, and Sikhs crossing the newly formed borders, often in overcrowded trains, on foot, or in large groups. This mass migration was accompanied by widespread communal violence, with families separated, property abandoned, and countless lives lost. The exact number of fatalities remains disputed, but historians widely consider the period as one of the greatest humanitarian catastrophes of the 20th century.

One complex issue left by the partition was the princely state of Jammu and Kashmir, which initially sought independence. Following an invasion by Pakistani tribal forces, the Maharaja of Kashmir signed an Instrument of Accession to India, leading to the ongoing conflict in the region. While the Radcliffe Line established the broader India-Pakistan territorial framework, Kashmir's accession followed a separate political and military process.
