The Kashmir dispute dates from 1947. The partition of the Indian sub-continent along religious lines led to the formation of India and Pakistan. However, there remained the problem of over 650 states, run by princes, existing within the two newly independent countries.
In theory, these princely states had the option of deciding which country to join, or of remaining independent. In practice, the restive population of each province proved decisive.
The people had been fighting for freedom from British rule, and with their struggle about to bear fruit they were not willing to let the princes fill the vacuum.
Although many princes wanted to be “independent” (which would have meant hereditary monarchies and no hope for democracy) they had to succumb to their people’s protests which turned violent in many provinces.
Because of its location, Kashmir could choose to join either India or Pakistan. Maharaja Hari Singh, the ruler of Kashmir, was Hindu while most of his subjects were Muslim. Unable to decide which nation Kashmir should join, Hari Singh chose to remain neutral.
