British India
The partition of India split the former British India into the Union of India and the Dominion of Pakistan. Twelve provinces (Ajmer-Merwara-Kekri, Andaman and Nicobar Islands, Assam, Bihar, Bombay, Central Provinces and Berar, Coorg, Delhi, Madras, Panth-Piploda, Orissa, and the United Provinces) became provinces in India. Three (Baluchistan, North-West Frontier, and Sindh) were in Pakistan. Two (Bengal and Punjab) were split between India and Pakistan.
