Seventy-five years ago, Sir Cyril Radcliffe, a British lawyer, was commissioned to draw the borders that would divide British-ruled India into two new, independent nations: Hindu-majority India and mainly Muslim Pakistan.

He had just five weeks to do so despite having never travelled to India, which had been under British rule for 200 years.

The lines he drew triggered one of the largest forced mass migrations in modern history, with roughly 15 million people displaced and more than two million people killed.

The boundary between the two nations became known as the Radcliffe Line and was officially announced on August 17, 1947, days after the independence of India and Pakistan.

Radcliffe was asked to base his lines on the population of Muslims and Hindus, in addition to “other factors”. These additional factors were never officially defined but are believed to include economic and communication resources, such as irrigation channels and railway lines.

The information on population, railways and rivers is based on the archived maps from The Imperial Gazetteer of India of 1931.

How India, Pakistan and Bangladesh were formed

The process of partition was not simple. In addition to the British-controlled territories, the subcontinent also consisted of many other territories controlled by the French, Portuguese or Omani rule, as well as more than 500 sovereign princely states ruled by local monarchs.

Upon independence, the British gave the princely states the option to join India or Pakistan – by signing the Instrument of Accession – or to remain independent. Some of these territories and princely states did not become part of India or Pakistan until recently.

Today, Kashmir remains the only region of British India that has not been fully integrated into one of the two nations or gained political independence.
