This study adopts a Discourse Analytical approach to investigate how a form of Iranian nationalism is represented and reproduced on popular social networks, particularly on Twitter, in response to the growing emergence of ‘the minority issue’ and reaction to their ethnic claims and demands. With ‘the minority issue’ resurfaced in public debates in recent years, particularly in social networks, Iranian nationalists are to directly respond and take a stand on issues like the place of minorities in modern Iran, the state’s role regarding cultural diversity, and the relation between the mostly Persian-speaking Shiite center and the non-Persian-speaking Sunni peripheries. While there is an optimistic argument that social networks can turn into a new, easily accessed and managed space for cultural inclusivity, minorities recognition and pluralized participation of ordinary citizens, Iranian nationalists, feeling threatened by the growing number of ethnolinguistic movements, seize the opportunity provided by social networks to construct a reactionary Iranian nationalism and to categorically reject ethnic demands as an existential threat to the country’s political integrity and cultural homogeneity. With the help of Twitter which features the convergence of the production, consumption, and circulation of information in one technology and offers opportunities for the fast-spreading of information through networks of contacts, Iranian nationalists propagate numerous myths of Persian origins and ancestry and memories of the Persian ‘golden age in the hope of creating a sense of intimacy with and devotion to the country.
