Book excerpt: This massive, four-volume work provides students with a close examination of 10 modern genocides enhanced by documents and introductions that provide additional historical and contemporary context for learning about and understanding these tragic events. Modern Genocide: The Definitive Resource and Document Collection spans nearly 1,700 pages presented in four volumes and includes more than 120 primary source documents, making it ideal for high school and beginning college students studying modern genocide as part of a larger world history curriculum. The coverage for each modern genocide, from Herero to Darfur, begins with an introductory essay that helps students conceptualize the conflict within an international context and enables them to better understand the complex role genocide has played in the modern world. There are hundreds of entries on atrocities, organizations, individuals, and other aspects of genocide, each written to serve as a springboard to meaningful discussion and further research. The coverage of each genocide includes an introductory overview, an explanation of the causes, consequences, perpetrators, victims, and bystanders; the international reaction; a timeline of events; an Analyze section that poses tough questions for readers to consider and provides scholarly, pro-and-con responses to these historical conundrums; and reference entries. This integrated examination of genocides occurring in the modern era not only presents an unprecedented research tool on the subject but also challenges the readers to go back and examine other events historically and, consequently, consider important questions about human society in the present and the future.
