"Saint Joan" is a play written by George Bernard Shaw that tells the story of Joan of Arc, a young peasant girl who believes she is chosen by God to lead the French army during the Hundred Years' War. The play explores her journey as she gains the trust of Charles VII, the Dauphin of France, and helps him reclaim his throne from the English. The narrative also delves into the themes of faith, nationalism, and the conflict between individual conviction and societal norms. Ultimately, Joan is captured, tried for heresy, and executed, but her legacy endures, leading to her canonization as a saint by the Catholic Church.
