This important volume examines history's darker side: the massacres, terrorist attacks, ethnic cleansing, and subjugation of races that have taken place throughout the history of humankind. Through examination of acts of brutality such as the Crusades, the Holocaust, the Hutu massacre of the Tutsis in Rwanda, recent terrorist attacks committed by al-Qaeda and ISIS, and many others, readers will be forced to confront the violence that continues to plague the human race. Sidebars, a glossary, and books and websites in the further reading section are also included.
