Bilateral talks were suspended in 2008 after an attack by Pakistani militants in Mumbai , India 's most populous city , killed more than 160 people . The negotiations have since resumed . The conflict over Kashmir dates back to 1947 , after Britain relinquished control of the Indian subcontinent , giving birth to modern India and Pakistan . Kashmir was free to accede to either nation . Maharaja Hari Singh , the ruler of the kingdom at the time , initially chose to remain independent but eventually opted to join India , thereby handing key powers to the central government in New Delhi . In exchange , India guaranteed him military protection and vowed to hold a popular vote on the issue . The South Asian rivals have fought two full-scale wars over the territorial issue . Islamabad has always said that majority-Muslim Kashmir should have been a part of Pakistan . A United Nations resolution adopted after the first war called for a referendum allowing the people of Kashmir to choose which country they wanted to join , but that vote for self-determination has never been held . Pakistan wants that referendum to take place . India says that Pakistan lends support to separatist groups fighting against government control and argues that a 1972 agreement mandates a resolution to the Kashmir dispute through bilateral talks .
