The Duke of Burgundy refers to a title historically held by the rulers of the Duchy of Burgundy, a significant region in what is now eastern France. This title became prominent in the late Middle Ages, particularly during the 14th and 15th centuries, when the dukes wielded considerable political power and influence in Europe. The most notable duke was Philip the Good, who expanded the duchy and played a key role in the politics of the time. The Duchy of Burgundy was known for its wealth, culture, and art, contributing to the flourishing of the Burgundian School of painting. The region was also a center for trade and commerce, connecting various parts of Europe. The title eventually became less significant after the duchy was absorbed into the Kingdom of France in the 15th century.
