 In addition, Nehru's stance as an unfailing nationalist led him to also implement policies which stressed commonality among Indians while still appreciating regional diversities.This proved particularly important as post-Independence differences surfaced since British withdrawal from the subcontinent prompted regional leaders to no longer relate to one another as allies against a common adversary.While differences of culture and, especially, language threatened the unity of the new nation, Nehru established programs such as the National Book Trust and the National Literary Academy which promoted the translation of regional literatures between languages and also organised the transfer of materials between regions.
