The House of Valois-Burgundy was a significant noble family in medieval Europe, originating from the Valois dynasty in France. It emerged in the late 14th century when Philip the Bold, the Duke of Burgundy, married Margaret III of Flanders, uniting their territories and wealth. This union expanded the influence of Burgundy, making it a powerful state in the region. The house played a crucial role in European politics, particularly during the Hundred Years' War and the Burgundian Wars. Its members, including Philip the Good and Charles the Bold, sought to consolidate power and territory, often clashing with France and the Holy Roman Empire. The house's decline began in the late 15th century, leading to its eventual absorption into the Habsburg dynasty.
