This series analyses the social, political and historical conditions that make ethnic cleansing possible. This episode begins with the persecution of Jews throughout history and then looks at the colonisers in Africa, Australia, South and North America, who justified brutal expansion in the name of 'civilising' the native peoples; then considers ethnic cleansing for political ends (Stalin's Great Purge, Nazi genocide, the American Indian exterminations) and concludes with why neighbour turned on neighbour as in Yugoslavia, Rwanda and Sri Lanka.
