In the riots that accompanied the partition in Punjab Province, it is believed that between 200,000 and 2,000,000 people were killed in what some have described as a retributive genocide between the religions while 50,000 Muslim women were abducted and raped by Hindu and Sikh men, 33,000 Hindu and Sikh women also experienced the same fate at the hands of Muslims. Around 6.5 million Muslims moved from India to West Pakistan and 4.7 million Hindus and Sikhs moved from West Pakistan to India. It was the largest mass migration in human history. A subsequent dispute over the princely state of Jammu and Kashmir eventually sparked the Indo-Pakistani War of 1947–1948.
