The world is an increasingly angry place. Fueled by economic turmoil, conflict, climate collapse and culture wars, outbursts of collective anger are visible online, on the streets, and in various political forums. These outpourings of visible, collective ire, what we call ‘amplified anger’, have been historically condemned in mainstream public discourse as anti-democratic, uncivil attacks on human co-existence. But for the people engaged in these acts of rage, anger is often seen as a fully legitimate, necessary response to injustice, oppression or crisis. There is an urgent need to study the sources and rhetorics of legitimation that allow this amplified anger to flourish, be voiced, and spread within and across contemporary communities. ANGLE (anger, legitimised) will study how communities that feel their anger has been delegitimised seek to perform, communicate and justify this volatile emotion. Composed of four interconnected work packages (Fury, Venom, Rage and Wrath), the project will explore gendered, postcolonial, post-conversion and neo- religious iterations of anger in specific cultural sites across the globe. It uses a novel two-fold methodology: fieldwork and participant observation to access and study the localised ‘anger worlds’ of particular communities; and textual analysis to study print and online spaces where discourses of amplified anger intermingle to create wider, transnational ‘anger arenas’. ANGLE’s analytical framework will provide critical empirical insights into the dynamics of global political action. Through the innovative concept of the ‘grammar of anger’, we will compare the legitimation, transmission and ethics of amplified anger across local and global political sites. We will advance EU’s research environment by consolidating empirically informed anger studies, building an international consortium of anger scholars, and creating a significant repertoire of knowledge on the economic, cultural and political impact in the 21st century.
