When a spate of mass murders occurs, people often get the impression that this is a modern phenomenon and, since most of the mass murders heard about have occurred in America, the popular opinion is to think that it is an American phenomenon. Both impressions are false. Mass murders have been common throughout history, and other countries have played host to them too. This book correlates the many mass murders that have taken place all over the world and attempts to explain to the reader what some of the causes and effects of these murders have on society and culture.
