At the time of independence, India was divided into over 565 princely states and 17 provinces , which were integrated into the country under the leadership of Sardar Vallabbhai Patel and his Secretary V.P. Menon by 1948. Later in when the Indian constitution was being crafted in 1949, the First Schedule of the Constitution organized territories into:- Part A : Former Governors' provinces.
- Part B: Former Princely States or groups of Princely States.
- Part C: Territories managed by commissioners appointed by the President.
- Part D: Andaman and Nicobar Islands

The act replaced the previous structure with the creation of 14 states and 6 union territories :| Indian States and Union Territories (1956) | |
