Punjabi Hindus and 1947 Partition
Punjabi Hindus suffered a great deal due to partition of Punjab in 1947. They were a minority in areas of Pakistan. Many of the Hindus/Sikhs had to move to East Punjab and Muslims to West Punjab. Estimates range from 100,000 to upwards of a million people were killed in the riots following the partition and subsequent independence of Pakistan and later India from British colonial rule. Most of the Punjabi Hindus who moved from West Punjab settled in the areas which are now Indian state of Punjab, Delhi, Haryana, Western UP, and even as far as Mumbai.
