The aftermath of World War II saw the emergence of many new nation-states on the Asian geopolitical map and a simultaneous attempt by these states to claim the agency of nationhood and to create an aura of a homogenous national identity. Textbooks have been the most potent tools used by nations to inject an idea of a national memory - in many instances with utter disregard for fundamental contradictions within the socio-political milieu. In South Asia, political sensitivity towards transmission of the past is reflected in the attempts of these states to revise or rewrite versions which are most consonant with the ideology of dominant players (political parties, religious organizations, ministries of education, publishing houses, NGOs, etc.) concerning the nature of the state and the identity of its citizens. This paper highlights the fundamental fault lines in the project of nation-building in states in South Asia by locating instances of the revision or rewriting of dominant interpretations of the past. By providing an overview of various revisionist exercises in South Asia, an attempt will be made to highlight important issues that are fundamental to the construction of identities in this diverse continent.
