Saint Joan of Arc, a humble peasant girl from 15th-century France, experienced divine visions and voices from saints at a young age, commissioning her to liberate France from English domination during the Hundred Years' War. Despite her youth and lack of military experience, she led French forces to crucial victories, most notably at Orléans, and facilitated the coronation of Charles VII. Her unwavering faith, courage, and strategic brilliance transformed the tide of the war, though she was later captured, tried by an English-backed ecclesiastical court on false charges of heresy, and tragically martyred by burning at the stake in 1431. Canonized in 1920, Joan remains an enduring symbol of faith, national pride, and the extraordinary impact one individual, guided by conviction, can have on history.
