Isabella I (22 April 1451 – 26 November 1504) was Queen of Castile and León. She and her husband, Ferdinand II of Aragon, laid the foundation for the political unification of Spain under their grandson Carlos I, the first monarch of a unified Spanish kingdom.

She and her husband sponsored the voyage of Christopher Columbus, as well as the Spanish Inquisition. She bore Ferdinand five children, including Catherine of Aragon, the first wife of Henry VIII of England.

Isabella in Ruled Britannia[]

King Philip II of Spain named his daughter, Queen Isabella of England, for his own great-grandmother Isabella of Castile. In 1598, Spanish soldier and playwright Lope de Vega wrote El Mejor Mozo de España in honor of Isabella and her husband.[1] Isabella was played by Catalina Ibanez.[2]

Isabella in "Report of the Special Committee on the Quality of Life"[]

Queen Isabella and her husband King Fernando were approached by Cristóbal Colón to provide funding for an excursion to Asia by sailing across the Atlantic Ocean. The monarchs commissioned the Special Committee on the Quality of Life to look into the desirability and ramifications of of granting Colón the ships and men needed to attempt his goal. In 1491, the Committee concluded that such a trip would not be in Spain's best interest.[3]
