Why has the Kashmir region been disputed by India and Pakistan since 1947?

The dispute over the Kashmir region originated following the partition of the Indian subcontinent in 1947. Under the terms of the partition, rulers of princely states were granted the right to choose between joining India or Pakistan, or remaining independent.1

The conflict began when Hari Singh, the maharaja of Kashmir, initially sought to maintain independence. However, following a revolution among his Muslim subjects and the intervention of Pashtun tribesmen, he signed an Instrument of Accession to India in October 1947. This act prompted immediate intervention from both nations: India sought to confirm the accession, while Pakistan viewed the state as a natural extension of its own territory.1

The resulting war ended with a United Nations-brokered ceasefire in 1949. A ceasefire line, later formalized as the Line of Control in 1972, divided the region. Neither country recognizes this line as an international boundary, and the region remains a point of contention between India, Pakistan, and China.1234
