Explanation:

1948: The Dhar commission submits its report opposing the formation of states on linguistic lines, saying that such move will be against national interest.The boundaries of the provinces in pre-1947 were drawn in a haphazard manner, and were not on linguistic basis and thus most provinces were multilingual and multicultural.It was incorporated in the Congress Party’s manifesto of 1945-46 that the provinces were to be redistributed on a linguistic basis. The promise was backed with the argument that it would make the administration easier, in view of to make linguistic identities in front, in place of more controversial ones, like caste and religion-based identities.
