Philip III the Good (French: Philippe le Bon; Dutch: Filips de Goede; 31 July 1396 – 15 June 1467) ruled as Duke of Burgundy from 1419 until his death in 1467. He was a member of a cadet line of the House of Valois, to which all 15th-century kings of France belonged. During his reign, the Burgundian State reached the apex of its prosperity and prestige, and became a leading centre of the arts.
Duke Philip has a reputation for his administrative reforms, for his patronage of Flemish artists (such as Jan van Eyck) and of Franco-Flemish composers (such as Binchois), and for the 1430 seizure of Joan of Arc, whom Philip ransomed to the English after his soldiers captured her, resulting in her trial and eventual execution. In political affairs, he alternated between alliances with the English and with the French in an attempt to improve his dynasty's powerbase. Additionally, as ruler of Flanders, Brabant, Limburg, Artois, Hainaut, Holland, Luxembourg, Zeeland, Friesland and Namur, he played an important role in the history of the Low Countries.
