After the Partition of British-India, from October–November 1947, in the Jammu region of the princely state of Jammu and Kashmir, many Muslims were massacred and others driven away to West Punjab. The killings were carried out by extremist Hindus and Sikhs, aided and abetted by the forces of Maharaja Hari Singh.
The exact number of casualties in the killings that continued for two months is not known, but estimates range from 20,000 to 237,000 and nearly half million were forced into displacement across the border into the newly created nation of Pakistan and its administered part of Kashmir.
