Why jammu and kashmir belongs to India?

Jammu and Kashmir's accession to India occurred in October 1947 when Maharaja Hari Singh signed the Instrument of Accession, amidst an invasion by tribal militias from Pakistan. This agreement granted India control over defense, foreign affairs, and communications while the Maharaja retained internal autonomy. The legitimacy of this accession is supported by the majority of the region's population, which has historically identified more with India. Despite ongoing disputes, Jammu and Kashmir's status as an integral part of India is upheld by the Indian government and is recognized in various international contexts.
