Joan of Arc is known for her leadership during the Hundred Years' War, a conflict between England and France that spanned from 1337 to 1453. A peasant girl claiming to have received visions from saints, she buoyed French morale during a low point in the war. Her most notable achievement was leading French forces to victory at the Battle of Orléans in 1429, which was a turning point in the war. Joan’s leadership helped inspire a sense of national identity and unity among the French. Captured by the English, she was ultimately executed but later became a symbol of French national pride and martyrdom.
