Though it was commonly recognized at the time of Independence that the Indian states were created not on a rational basis, but were the result of the exigencies of the progressive British conquest of the subcontinent, and Congress had been advocating the reorganization of provinces for over a quarter century prior, a commission that had been set up in 1948 by the Government of India, tasked with drawing up clean-cut states corresponding to demographic and linguistic boundaries, was not effective in the northern part of the country, as it reconsidered its position on the north. While states across the country were extensively redrawn on linguistic lines at the behest of linguistic groups, the only languages not considered for statehood were Punjabi, Sindhi and Urdu. Its jurisdiction was limited to the southern states, with northern India kept out of its purview, specifically to avoid problems like those of Punjab, in particular issues raised by the Sikhs.
