Hindi Diwas commemorates the day when the Constituent Assembly of India accepted Hindi as the official language of the country along with English. The listing of Hindi as official language took place on September 14, 1949.
Two years following Independence, the newly formed administration was reeling under the pressure to bring together the multiple linguistic, cultural and religious groups of the nation. The unification of the country had to be done along with giving it a unique national flavour. In a country that did not have any one language giving it a unique national identity, Hindi provided itself as the solution for unification.
