The partition of India split British India into the countries of India and Pakistan (East and West 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 Choudhary Rehmat Ali, due to presented religious issues. Pakistan became a Muslim country, and India became a majority Hindu but secular country. The main spokesperson for the partition was Muhammad Ali Jinnah. He became the first Governor-General of Pakistan.
