 The most contentious of the disputes was , and continues to be , that over the princely state of Kashmir . It had a Muslim @-@ majority population and a Hindu maharaja , Sir Hari Singh , who stalled his decision on which nation to join . With the population in revolt in October 1947 , aided by Pakistani irregulars , the maharaja acceded to India ; Indian troops were airlifted in . Jinnah objected to this action , and ordered that Pakistani troops move into Kashmir . The Pakistani Army was still commanded by British officers , and the commanding officer , General Sir Douglas Gracey , refused the order , stating that he would not move into what he considered the territory of another nation without approval from higher authority , which was not forthcoming . Jinnah withdrew the order . This did not stop the violence there , which has broken into war between India and Pakistan from time to time since .
