They employed a brutality which is staggering by today's standards. A fresh look at some of the world's most fascinating, iconic, and truly ruthless leaders, the new series Ancients Behaving Badly cuts through the folklore to present an accurate portrait of characters from Alexander the Great to Genghis Khan, Caligula to Cleopatra. Using the latest historical discoveries, forensic science tests, archaeological finds, analysis of torture instruments, and battlefield dynamics, The History Channel sheds light on these leaders and how they really came to power (most killed off family members), how they treated their subjects, friends and family, how they were so successful in keeping their power, the battlefield leadership they demonstrated, and how they achieved such spectacular transformations at home. Expert interviews, on-location shooting, and CGI to help to recreate their environments, and provide stunning reenactments. / (Source: History Channel)
