Responsibility for the Holocaust
Responsibility for the Holocaust has been the subject of historical debate concerning the development and origins of the Holocaust across Europe. While the responsibility for the Holocaust rests largely on Hitler and the Nazi Party's leadership, operations to persecute Jews, Poles, Romani people, homosexuals and others were also perpetrated by the Schutzstaffel (SS), the Wehrmacht, and ordinary German citizens, as well as by collaborationist members of various European governments, including soldiers and civilians.
