Although the term "genocide" was coined by humanitarian Rafael Lemkin in reference to the Turkish expulsion and slaughter of Armenians in the early 20th century, the phenomenon is as old as civilization. In this program, a variety of experts analyze Biblical accounts and some of the earliest documented examples of genocide, as in the Athenian siege of Milos in 416 BC, to explore the psychology that motivates such violence. This grim survey of history looks at the extermination of Tasmanians, Native Americans, Namibia's Herero tribe, and the Armenians. Guests include Nobel Laureate Elie Wiesel, Executive Director of Amnesty International USA William Schulz, and David Scheffer, U.S. Ambassador at Large for War Crimes.
