Conflict theory has downplayed the role of emotions or categorized them as individual, cultural, or irrational phenomena. This paper argues that emotions grow out of situational interactions and that accumulated levels of emotions, emotional energy (EE), fuel the agency of conflicting parties. Drawing on theory of EE and positive emotions, three emotional dynamics of conflicts are proposed: (1) positive EE, such as confidence and trust, promotes action; (2) negative EE, such as righteous anger and resentment, drives conflictual action; and (3) loss of EE dispirits actors in shame and hopelessness. Research questions exemplified by the Arab Spring are suggested relative to three themes: mobilization of collective EE, emotional dynamics influencing political elites, and violent and nonviolent conflict escalation.
