The title "Duke of Provence" refers to a noble rank historically associated with the region of Provence in southeastern France. The title was established in the medieval period and was often held by members of the House of Capet, a prominent royal family. The Duke of Provence played a significant role in the political and cultural life of the region, influencing local governance and alliances. In the 15th century, the title became less prominent as Provence was integrated into the Kingdom of France. Today, the title is largely ceremonial and is sometimes used in modern contexts to evoke the historical significance of the region and its noble heritage.
