Robert, Count of Clermont in the context of Prince du sang

The House of Bourbon (English: /ˈbʊərbən/, also UK: /ˈbɔːrbɒn/; French: [buʁbɔ̃]) is a dynasty that originated in the Kingdom of France as a branch of the Capetian dynasty, the royal House of France. Bourbon kings first ruled France and Navarre in the 16th century. A branch descended from the French Bourbons came to rule Spain in the 18th century and is the current Spanish royal family. Other branches, descended from the Spanish Bourbons, held thrones in Naples, Sicily, and Parma. Today, Spain and Luxembourg have monarchs from the House of Bourbon.

The royal Bourbons originated in 1272, when Robert, the youngest son of King Louis IX of France, married the heiress of the lordship of Bourbon. The house continued for three centuries as a cadet branch, serving as nobles under the direct Capetian and Valois kings.

Duke of Bourbon (French: Duc de Bourbon) is a title in the peerage of France. It was created in the first half of the 14th century for the eldest son of Robert of France, Count of Clermont, and Beatrice of Burgundy, heiress of the lordship of Bourbon. In 1416, with the death of John of Valois, the Dukes of Bourbon were simultaneously Dukes of Auvergne.

Although the senior line came to an end in 1527, the cadet branch of La Marche-Vendome would later succeed to the French throne as the Royal House of Bourbon, which would later spread out to other kingdoms and duchies in Europe. After this date, the title was given to several Princes of Condé and sons of the French Royal family.
