The document provides an overview of genocide throughout history and discusses ongoing cases today. It defines genocide as the systematic killing or destruction of a racial, religious or national group. The Holocaust is used as a prominent example where over 11 million Jews and others were killed by Nazi Germany. Reasons for genocide include one group believing in its own racial superiority and blaming others for economic or social problems. The Darfur genocide is highlighted as an ongoing case today where over 400,000 civilians have been killed by government-backed militias in Sudan. Citizens are urged to recognize signs of genocide and put political pressure on governments to intervene through the UN.
