Partition of India
The 1947 British division of colonial India into India and Pakistan, whose rushed borders triggered mass migration and communal killing on a historic scale.
In the summer of 1947, a British lawyer who had never set foot in India was handed a stack of outdated census maps and about five weeks to cut a subcontinent in two. Cyril Radcliffe's pencil split roughly 88 million people between a Hindu-majority India and a Muslim-majority Pakistan, and the frenzy that followed became one of the largest and bloodiest upheavals of the twentieth century.
The rushed line
Radcliffe arrived in Delhi on July 8, 1947, to chair the two boundary commissions dividing the mixed provinces of Punjab in the west and Bengal in the east. He had never visited India and knew almost nothing of its geography, yet the last viceroy, Lord Mountbatten, had moved independence forward to August 15, leaving barely a month for the work. Radcliffe finished, took no fee, and later burned his papers. His line was published on August 17, two days after the flags had already changed, so millions woke as citizens of a country without knowing which one they now belonged to. The awards had been finished earlier but were held back so the boundary would not sour the independence celebrations, a secrecy many later blamed for the chaos that erupted once people finally learned which side of the line they were on. Pakistan itself was born in two pieces, a western wing and an eastern wing separated by nearly a thousand miles of Indian territory. That eastern wing broke away after another war in 1971 to become Bangladesh.
The human cataclysm
The announcement set off the largest mass migration in recorded history. Somewhere between 10 and 15 million people fled across the fresh borders, Hindus and Sikhs moving toward India, Muslims toward Pakistan, most of them on foot in columns that stretched for miles. The violence that met them was intimate and merciless. Villages were burned, refugee trains pulled into stations filled with the dead, and women were abducted and assaulted by the tens of thousands. Estimates of those killed range from one to two million. Punjab and Bengal, the two provinces the line actually cut, absorbed the worst of the slaughter, and the horror crossed every community rather than sparing any.
The unfinished business
One piece was left deliberately undecided. The princely state of Jammu and Kashmir had a Hindu maharaja, Hari Singh, ruling over a Muslim majority, and he stalled rather than join either new dominion. When armed tribesmen crossed in from the Pakistani side in October 1947, he signed the state over to India in exchange for military help, igniting the first India-Pakistan war. The fighting froze along a ceasefire line that still slices through Kashmir today. Nearly eight decades on, the pencil stroke of 1947 remains a live wound, and the rivalry it opened has hardened into a standoff between two nuclear-armed neighbors who still cannot agree where the border belongs.
