Louis I, Duke of Orléans
Beginning in 1392, King Charles VI began to show increasing signs of madness. Two princes of the royal family, Louis I, Duke of Orléans, the younger brother of the king, and John the Fearless, Duke of Burgundy, began a battle for the control of Paris. On 23 November 1407, Louis of Orléans was murdered on the streets of Paris by agents of the duke of Burgundy, who took over the royal administration. The son of the murdered duke, Charles of Orléans, pretended to accept the Burgundians, but quietly assembled a coalition of other nobles, including the Dukes of Berry and Bourbon, the count of Alençon, and the count of Armagnac. They became known as the Armagnacs. Their feud turned into the Armagnac–Burgundian Civil War.
