Frequently asked questions

Isabella I of Castile (1451–1504) is one of the most remarkable monarchs of the Spanish Renaissance. What you need to remember is that she unified Spain by marrying Ferdinand II of Aragon, thus forming the Catholic Monarchs. Her reign is best known for funding the voyage of Christopher Columbus in 1492, which opened the era of great discoveries and colonization of the Americas. But what stands out is the density of her actions: she also completed the Reconquista with the capture of Granada that same year, established the Spanish Inquisition in 1478, and thoroughly reformed the administration of her kingdom.

Ordinances of Toledo — Administrative Reform (1480)

Patronage of Letters and the University of Alcalá (1499)

Isabella actively supported the humanist revival in Spain, funding Cardinal Cisneros in the founding of the University of Alcalá de Henares, which would become a major intellectual center of the Iberian Renaissance.

Treaty of Tordesillas (1494)

Anecdotes

Isabella I of Castile was born on April 22, 1451, in Madrigal de las Altas Torres, into a modest royal family. Her path to the throne was far from assured: she had to face a civil war against her niece Joanna la Beltraneja, supported by Portugal, before establishing herself as the legitimate queen of Castile in 1479.

In 1469, Isabella secretly married Ferdinand of Aragon without the consent of her half-brother King Henry IV. The two young people disguised themselves as merchants to meet in Valladolid, defying the conventions of the time. This union would lay the foundation for the future unified Spanish monarchy.

It was Isabella who personally funded Christopher Columbus's project after he had suffered numerous rejections. According to legend, she offered to pawn her jewels to finance the expedition, although historians believe that royal funds were actually mobilized. Columbus's caravel set sail on August 3, 1492.

Isabella was renowned for her keen sense of justice: she personally traveled through her kingdoms with a traveling court to administer justice directly to her subjects, including the most humble. She always carried royal documents with her and received petitions even during her military campaigns.

During the Granada War (1482–1492), Isabella played an active role at the front by organizing troop supplies and visiting the wounded in field hospitals she had herself established — a pioneering initiative in the history of European military medicine.
