Charles II (11 September 1365 – 25 January 1431), called the Bold (French: le Hardi) was the Duke of Lorraine from 1390 to his death and Constable of France from 1418 to 1425.
Charles joined the Barbary Crusade, fought at Nicopolis, and aided the Teutonic knights in Livonia. During the Hundred Years War, he sought closer ties to the French royal family, even being made Constable by Queen Isabella. Following an indecisive war against his nephew, he died in 1431.
