Post Independence Integration of India: Need for integration of India was necessitated by many factors such as varying size of different states i.e. either too large or too small in area and population and the large number of states i.e. more than 500 princely states which had to be merged with one state or the other. For solving this problem from administrative point of view, States Reorganisation Commission was formed. Decision was taken after discussions and consultations that the states should be reorganised on the basis of language. Accordingly, Madras was divided into Mysore, Andhra Pradesh and Madras. Later Madras was renamed Tamil Nadu. Mysore was renamed as Karnataka.
Bombay state was divided into Gujarat and Maharashtra, central province to Madhya Pradesh. Rajasthan whose integration process had already started, was affirmed as Rajasthan state. In 1966 Punjab and Haryana states were formed. In November 2000 Uttranchal now Uttarakhand was separated from Uttar Pradesh. Chhatisgarh has been separated from Madhya Pradesh, and similarly Jharkhand from Bihar. Currently by dividing Andhra Pradesh Telangana is formed. Same demand is raised to create Bundelkhand and Vidarbha States but these are not organized yet.
