"the suzerainty of His Majesty over the Indian States lapses, and with it, all treaties and agreements in force at the date of the passing of this Act between His Majesty and the rulers of Indian States". States were thereafter left to choose whether to join India or Pakistan or to remain independent. Jammu and Kashmir, the largest of the princely states, had a predominantly Muslim population ruled by the Hindu Maharaja Hari Singh. He decided to stay independent because he expected that the State's Muslims would be unhappy with accession to India, and the Hindus and Sikhs would become vulnerable if he joined Pakistan. On 11 August, the Maharaja dismissed his prime minister Ram Chandra Kak, who had advocated independence. Observers and scholars interpret this action as a tilt towards accession to India.

Several sources indicate that the plans were finalised on 12 September by the Prime Minister Liaquat Ali Khan, based on proposals prepared by Colonel Akbar Khan and Sardar Shaukat Hayat Khan. One plan called for organising an armed insurgency in the western districts of the state and the other for organising a Pushtoon tribal invasion. Both were set in motion.

Large numbers of Hindus and Sikhs from Rawalpindi and Sialkot started arriving in March 1947, bringing "harrowing stories of Muslim atrocities." According to Ilyas Chattha, this provoked counter-violence on Jammu Muslims, which had "many parallels with that in Sialkot." The violence in the eastern districts of Jammu that started in
