For nearly a millennium, barbarian hordes rose up and swept across Asia, Europe and Africa, pillaging towns and sacking empires. But who were these Barbarians, seemingly devoted only to violence and destruction, their language the battle-axe and mighty sword. Shot on location by Emmy Award-winning documentarian Robert Gardner this documentary utilises in-depth interviews, thrilling reenactments and narration by Clancy Brown to bring to life the powerful leaders, military strength and overwhelming drive that kept empires in terror for centuries.
