Prior to freedom India was also divided on the basis of language, the freedom fighters like Mahatma Gandhi and some other leaders promised that the free India would be based on new set of provinces and one principal language.

In 1947 when India became free from British rulers it was also divided on the basis of religion and language, so the Congress leaders were hesitating to announce a principal language because they were afraid that it may result in more partitions.

But later on the states were reorganized on linguistic basis such as Punjab was reorganized in April 1966 and the hindi region of Punjab was transferred to Himachal Pradesh.

As per my opinion the linguistic organisation of state has helped India by strengthening the unity and integrity of the country.
