Armagnac–Burgundian Civil War
The Armagnac–Burgundian Civil War was a conflict between two cadet branches of the French royal family — the House of Orléans (Armagnac faction) and the House of Burgundy (Burgundian faction) from 1407 to 1435. It began during a lull in the Hundred Years' War against the English and overlapped with the Western Schism of the papacy.
