Whether defined as political concept, ideology, identity, claim, sentiment, or group’s state of mind, nationalism has continued to be a major political imaginary of the last two centuries, advancing the idea of popular sovereignty and leading to successive reconfigurations of the world’s map. The emergence of new transnational institutions, global markets, movements, and publics, along with the rise of new overlapping identities, have not tempered the tenacity of nationalism and ethnic attachments. Instead, as John Dunne points out, nationalism -- a common idiom of contemporary feeling -- remains the air we breathe daily. In this course we will examine the plurality of concepts and forms of both nation and nationalism, and try to understand the sources of the more recent alarming upsurge of a new nationalism -- a fusion of ethno-nationalism, xenophobia, ultra-populism and new articulations of fascism, that openly resort to violence. Informed historically and theoretically, our discussions will consider material from a variety of sources, and examine cases from different parts of the world.
