Joan of Arc - New World EncyclopediaJoan of Arc is a national heroine of France and a saint of the Roman Catholic Church. She had visions, from God, that led to the liberation of her homeland from English dominance in the Hundred Years' War; however she was captured, tried for heresy and martyred. Today she is honored as an example of female courage and leadership, piety, and devotion, as well as a French patriot. Though illiterate, uneducated, dying at the young age of 19, her impact on history is enormous, stemming from the belief of a 16-year-old, that she was an instrument of God.
