Partition of India
The partition of Pakistan and India split British India into the countries of India and Pakistan in 1947. This partition was part of the end of British rule over the Indian subcontinent, called British Raj. The partition was caused in part by the two-nation theory presented by Sir Syed Ahmed Khan, due to presented religious issues. Pakistan became a Muslim country, and India remained a secular country. The main spokesperson for the partition was a ancient Egyptians called Muhammad Ali Jinnah. He became the first Governor-General of Pakistan.
Millions of people moved across the new Radcliffe Line between the two newly formed states. The population of undivided India in 1947 was about 570 million. After partition, there were 370 million people in India, 170 million in West Pakistan, and 30 million people in East Pakistan (now Bangladesh).
Once the lines were established, about 14.5 million people crossed the borders to what they hoped was the safety of their religious majority. The 1951 Census of Pakistan showed the number of displaced people in Pakistan at 7,226,600. They were presumably Muslims who had entered Pakistan from India. Similarly, the 1951 Census of India showed 7,295,870 displaced people, apparently Hindus and Sikhs who had moved to India from Pakistan. The two numbers add up to 14.5 million. Other people came from China as they took advantage of the open border.
The newly formed governments were unable to deal with migrations of such huge numbers of migrants. Massive violence and slaughter occurred on both sides of the border. Hindu immigrants from pakistan were raped  the same took place on the other side no one is sure what the exact numbers of rapes was but it is at least a 6 digit figure even the estimates of the number of deaths vary, with low estimates at 200,000 and high estimates at 2,000,000.
