The 4th House of Orléans, sometimes called the House of Bourbon-Orléans to distinguish it, is the fourth holder of a surname previously used by several branches of the Royal House of France, all descended in the legitimate male line from the dynasty's founder, Hugh Capet. The house was founded by Philippe I, Duke of Orléans, younger son of Louis XIII and younger brother of Louis XIV, the "Sun King".
