Genocide can be defined as acts committed with intent to destroy, in whole or in part, a national, ethnic, racial, or religious group. Author Linda Jacobs Altman examines genocide throughout the ages, focusing especially on the Holocaust, forced famine in the Ukraine under Stalin, war against the American Indians, Cambodia's killing fields, and such recent examples as conflicts in Bosnia and Darfur. She looks at what causes this horrific practice and what might be done to avert it in the future.
