Although the Queen had several Converso counselors, the monarchs' Catholic views led them to end the independence of Moors in the Iberian Peninsula with the conquest of Granada and to force the expulsion or conversion of thousands of SephardicJews. The Spanish Inquisition, inspired by earlier European Inquisitions, was created by their royal decree.
Their joint motto was Tanto monta, monta tanto ("It amounts so, so it amounts").
It was created by Antonio de Nebrija and was either:
an allusion to the Gordian knot: Tanto monta, monta tanto, cortar como desatar ("..., cutting as untying")
explaining the equal footing for both monarchs in the governance of Castile: Tanto monta, monta tanto, Isabel como Fernando ("..., Isabella as Ferdinand")
Their symbol was el yugo y las flechas, a yoke and a fasces of arrows. The yoke is another allusion to the Gordian knot. Y and F are the initials of Ysabel (archaic spelling) and Fernando. This symbol was later used by the Spanish fascist party the Falange, which claimed the glory and the ideals of the Reyes Católicos.
Isabella was great-great-granddaughter of both Henry II of Castile and his half-brother Peter I of Castile and their respective wives (Joan of Villena and Maria de Padilla).
Isabella and her husband had created an empire and in later years were consumed with administration and politics; they were concerned with the succession and worked to link the Spanish crown to the other rulers in Europe.
Isabella is entombed in Granada in the Capilla Real, which was built by her grandson, Charles V, Holy Roman Emperor (Carlos I of Spain), alongside her husband Ferdinand, her daughter Juana and Juana's husband Philip; and Isabella's 2-year old grandson, Miguel (the son of Isabella's daughter, also named Isabella, and King Manuel of Portugal).
The Catholic Monarchs (Spanish: los Reyes Católicos) is the collective title used in history for Queen Isabella I of Castile and King Ferdinand II of Aragon.
Ferdinand and Isabella were noted for being the monarchs of the newly-united Spain at the dawn of the modern era.
