The House of Bourbon-Parma is an Italian cadet branch of the House of Bourbon, whose members once ruled as King of Etruria and as Duke of Parma and Piacenza, Guastalla, and Lucca. The House descended from the French Capetian dynasty in male line. Its name of Bourbon-Parma comes from the main name (Bourbon) and the other (Parma) from the title of Duke of Parma. The title was held by the Bourbons, as the founder Philip, Duke of Parma who was the great-grandson of Ranuccio II Farnese, Duke of Parma, married Louise Élisabeth of France, getting the house of Bourbon, and the state of Parma, together. The House of Bourbon-Parma is today the Sovereign House of the Grand Duchy of Luxembourg (agnatically) and all members of the Grand Ducal Family of Luxembourg are members of the House of Bourbon-Parma with the title of "Princes/Princesses" and the predicate of Royal Highness.
