What happened
Independence left the map incomplete. When the British relinquished their claims to paramountcy, the Library of Congress country study records, the 562 independent princely states were given the option to join either of the two nations. Most acceded quickly to India or Pakistan. Jammu and Kashmir, a Muslim-majority state with a Hindu maharajah, hesitated, until armed tribesmen and regular troops from Pakistan infiltrated his domain, inducing him to sign the Instrument of Accession to India on October 27, 1947. The National Army Museum describes what followed: Indian troops were airlifted into Srinagar and managed to repel the Pakistani invaders, and a bitter war then raged across the state until a United Nations-sponsored ceasefire in 1948. The ceasefire line still divides Kashmir, leaving a dispute that has driven further wars since.
Why it matters
The integration of the princely states built the territorial India that exists today, and the unresolved status of Kashmir became the most dangerous fault line in South Asia, the trigger for repeated wars between two nations that both later acquired nuclear weapons.
How we know
The accession of the princely states and the Kashmir Instrument of Accession are documented in the Library of Congress India country study, and the course of the 1947-48 war and the UN ceasefire are recorded by the National Army Museum.
