Saint Olga: From Epic Revenge to Orthodox Sainthood The shocking true story of Princess Olga of Kiev - the medieval ruler who took the most creative revenge in history, then became a saint! After her husband was murdered in 945 AD, she buried enemies alive, burned down entire cities with fire-birds, and slaughtered thousands. Then she converted to Christianity and was canonized by the Orthodox Church. From brutal vengeance to sainthood - this is medieval history at its most unbelievable. #Mediev
