This teaching guide is based on genocide scholar Dr. Gregory H. Stanton’s work “Ten Stages of Genocide” (an update of his previous “Eight Stages of Genocide,” 1996.) The progression of stages is a formula for how genocide is prepared, carried out, and produces long-lasting repercussions.  Beginning with prejudice, genocide develops over time, involving the cooperation of a large number of people and the state; This lesson helps students understand genocide as a process that can be corrected and prevented.
