European Holocaust Studies (EHS) publishes key international research results on the murder of the European Jews and its wider contexts.In recent years, scholars have rediscovered Hannah Arendt`s "boomerang thesis"– the "coming home" of European colonialism as genocide on European soil– as well as Raphael Lemkin`s work around his definition of genocide and the importance of its colonial dimensions. Germany and other European states are increasingly engaging in debates on comparing the Holocaust to other genocides and cases of mass killing, memorialization, "decolonization" and attempts to come to terms with the past ("Vergangenheitsbewältigung").
