This work tries to explore into the factors which turned once-so revolutionary ideology at its inception into a reactionary ideology out to destroy its own creator. Big claims are made today that we live in a transnational global age which has bid adieu to nationalism and its impedimenta. But this claim soon loses its ground when it confronts the following: majoritarian racist attacks on immigrants, sports nationalism among the citizens, cross-border terrorism, non-emergence of a common parliament and government within EU framework. This work argues that this has been the case primarily because nationalism has been for most of its part led by the ruling class of the concerned nation-state. It further argues that we may be able to experience some positive aspects of nationalism if we reconcile this ideology with the subaltern classes. one such effort was made in colonial India by Ambedkar's conception of subaltern nationalism. This book looks with a hope at the young subaltern citizen.
