A continuation of the study of those factors that lead to persecutions and acts of genocide is presented. As students read the materials included in the case studies, they should be referred to the organizing concepts discussed in "Teaching about the Holocaust and Genocide: Introduction. The Human Rights Series, Volume I." Unit 1 in that volume defines the following five concepts as they apply to the roots of intolerance and persecution: denial of reality, indifference, prejudicial attitudes, conformity, and obedience to authority. Students reapply these concepts as they study about the forced famine in the Ukraine and the actions of the Khymer Rouge in Cambodia. (Author/BZ)
