Recent studies have demonstrated the importance of emotions in the escalation and reduction of intergroup conflicts. This paper reviews and discusses studies on emotions in intergroup conflict. This paper aims to understand recent findings and indicate future areas of focus regarding how emotions elicit discrimination, prejudice, and war. First, I introduce intergroup emotions theory, one of the most important theories on intergroup relations, and discuss the relation between intergroup emotions and intergroup aggression. Second, I examine collective emotions, which is the social or group phenomenon of sharing intergroup emotions across the entire group. Finally, I review studies on emotion regulation in intergroup conflicts and provide ways for resolving conflicts by intervening in real intergroup conflicts.
