‘Cologne Changed Everything’—The Effect of Threatening Events on the Frequency and Distribution of Intergroup Conflict in Germany

Abstract

Abstract In this article, I study the role that threatening events play in shaping both the occurrence and the distribution of intergroup conflict. Using the case of anti-refugee attacks in Germany, the study finds that the 2015 New Year’s Eve (NYE) sexual assaults led to a dramatic surge in the daily rate of violence, far surpassing the more short-lived effect of domestic and European terrorist attacks. Importantly, this effect was more pronounced among districts with low prior levels of anti-refugee hostility and far-right support. The NYE event both increased the frequency and changed the distribution of subsequent attacks—mobilizing new, previously peaceful communities to behave aggressively towards local refugee populations. Together, these findings reveal that threatening events not only affect the amount of intergroup conflict, but may also alter the structural conditions under which such conflict emerges in the first place.
