The missing pieces in Philip Valois's domain were the French provinces still held by the Plantagenet kings of England, who also claimed the French crown. Beginning in 1338, the Hundred Years' War eventually settled the contest. After France's victory in the final battle, Castillon (1453), the Valois were the ruling family, and the English had no French possessions left except Calais. Once Burgundy and Brittany were added, the Valois dynasty's holdings resembled modern France. Protestantism spread throughout France in the 16th century and led to civil wars. Henry IV, of the Bourbon dynasty, issued the Edict of Nantes (1598), granting religious tolerance to the Huguenots (French Protestants). Absolute monarchy reached its apogee in the reign of Louis XIV (1643?1715), the Sun King, whose brilliant court was the center of the Western world.
