The Hundred Years’ war between England and France gave us the victories of Crecy and Agincourt, and made the reputations of Edward III and Henry V. It gave France a national heroine in Joan of Arc. But, even now, the jury is out as to its causes and outcome. Was it the final swansong of a redundant knightly class whose only reason for being was to fight? Was it a battle over ever more important territory to the emerging economies of England and France? Or was it the painful birth of two distinct national identities, forged through their long and violent divorce? Dr Janina Ramirez guides us through the stories of kings, great knights, bloody battles and cultural triumphs of this momentous conflict.
