In 1947, as British rule over India ended, a hurried political decision split the subcontinent into India and Pakistan. This history looks past the men in the negotiating rooms to the confusion and hope of the ordinary people swept into a change few understood in advance.
Neighbouring countries can keep their hostility alive by each telling a carefully built national story about the event that divided them. Because the shared past is only partly understood, each side's version fills the gaps in its own favour. The old wound is kept open as a lens for seeing the other side.
A border can be drawn on a map long before anyone has worked out what it will mean on the ground. The people deciding the split, and most observers, could not even picture the shape of the new countries or how ordinary people would be affected. That blindness turned a political settlement into mass displacement.
When a departing ruler decides to divide a territory and leave quickly, the speed itself becomes a cause of disaster. Rushing the split left no time to prepare for what dividing communities would actually involve. The result was confusion, panic and violence on a huge scale.
A split sold as bringing political and religious freedom can instead bring uprooting and death. At least a million people were killed and ten to fifteen million were driven from their homes. The gains went to a few while the costs fell on the many.
New states born out of chaos carry that chaos into their foundations. The turmoil of the split soured what should have been a triumph of independence. Its effects are still felt generations later.
