Abstract
As conflict has at its basis a contest of ideas, values or resources between two or more groups, a comprehensive understanding of intergroup conflict must take into account the psychological processes that make groups and group behavior meaningful. Because individuals value and internalize identities relevant to their social, geographic, economic, historical and political positions, any devaluation, loss or imposed change to one of those identities is likely to be particularly threatening. The Social Identity Approach formulates an understanding of how these identity‐based motivations interact with social structures to predict intergroup conflict. Importantly, it also provides an explanation of how procedural justice mechanisms can be utilized to guide conflicting interests to common cooperative goals that can be accepted and pursued. By having representation and participation of relevant actors in the development of a shared identity, as is this case when nation states are formed or re‐created, threat is reduced, legitimacy built and the basis for positive intergroup relations created.
