The Royal Household and Heritage of the Crown of Spain (Spanish: Real Casa y Patrimonio de la Corona de España) was the institution that governed the organization of the Royal Spanish Court from the time of the Habsburg dynasty, which introduced the so-called Burgundian etiquette, up to the reign of Alfonso XIII, great-grandfather of the current King of Spain Felipe VI, in all that regarded the structure of the Court as well as the ceremonial matters, etiquette and protocol.
