In 1472, the next Duke of Burgundy, Charles the Bold, fought against Louis in the Burgundian Wars. However, Louis was able to separate Charles from his English allies by signing the Treaty of Picquigny (1475) with Edward IV of England. The treaty officially ended the Hundred Years' War. With the death of Charles the Bold at the Battle of Nancy in 1477, the dynasty of the Dukes of Burgundy ended. Louis took advantage of the situation to seize numerous Burgundian territories, including Burgundy itself and Picardy.
