Goldhagen argued that Germans possessed a unique form of antisemitism, which he called "eliminationist antisemitism", which developed over centuries prior to the 20th century. Goldhagen contends,
The German perpetrators of the Holocaust treated Jews in all the brutal and lethal ways that they did because, by and large, they believed that what they were doing was right and necessary. Second, that there was long existing, virulent antisemitism in German society that led to the desire on the part of the vast majority of Germans to eliminate Jews somehow from German society. Third, that any explanation of the Holocaust must address and specify the causal relationship between antisemitism in Germany and the persecution and extermination of the Jews which so many ordinary Germans contributed to and supported.
