The following is the family tree of the Spanish monarchs starting from Isabella I of Castile and Ferdinand II of Aragon till the present day. The former kingdoms of Aragon (see family tree), Castile (see family tree) and Navarre (see family tree) were independent kingdoms that unified in 1469 as personal union, with the marriage of the Catholic Monarchs, to become the Kingdom of Spain (de facto), up to the promulgation of the Nueva Planta decrees by Philip V in 1715 (unification de jure).
