During the Hundred Years' War, the 17-year-old French peasant Joan of Arc leads a French force in relieving the city of Orleans, besieged by the English since October.
During the next five weeks, Joan led French forces into a number of stunning victories over the English, and Reims, the traditional city of coronation, was captured in July. Later that month, Charles VII was crowned king of France, with Joan of Arc kneeling at his feet.
In May 1430, while leading another military expedition against the English occupiers of France, Bourguignon soldiers captured Joan and sold her to the English, who tried her for heresy. She was tried as a heretic and witch, convicted, and on May 30, 1431, burned at the stake at Rouen. In 1920, Joan of Arc, already one of the great heroes of French history, was recognized as a Christian saint by the Roman Catholic Church.
