Upon the Partition of British India into the Dominion of India and Dominion of Pakistan, 11 provinces (Ajmer-Merwara-Kekri, Andaman, Nicobar Islands, Bihar, Bombay, Central Provinces and Berar, Coorg, Delhi, Madras, Panth-Piploda, Orissa, and the United Provinces) joined India, 3 (Baluchistan, North-West Frontier, and Sindh) joined Pakistan, and 3 (Punjab, Bengal, and Assam) were partitioned between India and Pakistan.

In 1950, after the new Indian Constitution was adopted, the provinces in India were replaced by redrawn states and union territories. Pakistan, however, retained its five provinces, one of which, East Bengal, was renamed East Pakistan in 1956 and became the independent nation of Bangladesh in 1971.
