Bourbon-Busset Bourbon-Busset The Bourbon-Busset family is an illegitimate branch of the House of Bourbon, being thus agnatic descendants of the Capetian dynasty. Historically, they have been regarded as non-dynastic since decisions rendered by Louis XI of France. Possibly, however, the family may be canonically legitimate, in which case it is the most senior extant male-line branch of the Capetians, and senior to the Bourbons which reign today in Spain and Luxembourg and have in the past ruled France, Naples and Sicily, as well as to the House of Braganza, also Capetians by illegitimate descent. The head of the family uses the
House of Bourbon at least from the beginning of the 13th century, when the estate of Bourbon was ruled by the Sire de Bourbon who was a vassal of the King of France. The term House of Bourbon ("Maison de Bourbon") is sometimes used to refer to this and the House of Bourbon-Dampierre, the second family to rule the seigneury. In 1272, Robert, Count of Clermont, sixth and youngest son of King Louis IX of France, married Beatrix of Bourbon, heiress to the lordship of Bourbon and member of the House of Bourbon-Dampierre. Their son Louis was made Duke of Bourbon in 1327.
