Four ancient leaders. Two epic wars. Civilisations clash in a battle for supremacy – rewriting history forever. Fatal Conflicts: the Rise and Fall of Civilisations is a two-part documentary exploring two defining ancient rivalries: Xerxes vs Themistocles in the Second Greco-Persian War, and Hannibal vs Scipio in the Second Punic War. In each, a dominant empire, Persia or Carthage, faces a rising force, Greece or Rome.
