why did the ruler of kashmir join india
Jammu and Kashmir (princely state) At the time of the British withdrawal from India, Maharaja Hari Singh, the ruler of the state, preferred to become independent and remain neutral between the successor dominions of India and Pakistan.[3] However, an uprising in the western districts of the State followed by an attack by raiders from the neighbouring Northwest Frontier Province, supported by Pakistan, put an end to his plans for independence. On 26 October 1947, the Maharaja signed the Instrument of Accession joining the Dominion of India in return for military aid.[4] The western and northern districts presently known as Azad Kashmir and Gilgit-Baltistan passed to the control of Pakistan, while the remaining territory became the Indian state Jammu and Kashmir.[5]
Princely state During the period of the British Raj, there were four princely states in Balochistan: Makran, Kharan, Las Bela and Kalat. The first three acceded to Pakistan.[51][52][53][54] However, the ruler of the fourth princely state, the Khan of Kalat Ahmad Yar Khan, declared Kalat's independence as this was one of the options given to all princely states.[55] The state remained independent until it was acceded on 27 March 1948. The signing of the Instrument of Accession by Ahmad Yar Khan, led his brother, Prince Abdul Karim, to revolt against his brother's decision in July 1948, causing an ongoing and still unresolved insurgency.[56]
