Joan of Arc had several defining moments in her life that shaped her legacy. At a young age, she experienced visions claiming divine guidance, leading her to believe she was destined to save France during the Hundred Years' War. Her pivotal moment came when she rallied French troops at Orléans, resulting in a significant victory against the English. Eventually captured, she was tried for heresy and burned at the stake. Her steadfast faith and courage transformed her into a symbol of heroism and national identity in France, ultimately leading to her canonization in 1920.
