Spanish Inquisition
The Constant PrincessThe Spanish Inquisition is depicted as both a tribunal for testing religious conformity and a threat that gives force to Spain’s demand for a single faith. Its significance extends beyond punishment: in the account of Catalina’s life, its reach is associated with the expulsion and flight of learned communities, the loss of medical knowledge, and a lasting break between the queen and the religious assumptions in which she was raised.
Religious Conformity and Coercion
After the conquest of Granada, Spain’s rulers maintain that the people under their authority must profess the Catholic faith. The novel sets this policy against a solemn promise to Boabdil that Muslims would be safe under Christian rule and that Christians, Muslims, and Jews could live together with dignity. That promise does not hold. Within three months, the Jews are expelled and Muslims face threats; conversion becomes compulsory, and any remaining suspicion about a convert’s belief may bring the person before the Spanish Inquisition for examination.
The Inquisition’s power in this account lies partly in the uncertainty surrounding that examination. The stated standard is not simply outward conversion: a shadow of doubt can make faith itself subject to testing. The institution thus reinforces a wider regime of coercion, in which the choices presented to dissenters are to leave, convert, or face the consequences of religious prosecution. The narrative connects this pressure to a political purpose—the making of one nation and one people through one faith—without suggesting that the resulting unity is voluntary or that the earlier promise of coexistence survives.
Knowledge, Flight, and Cultural Loss
The institution’s reach is also associated with the removal of scholars and physicians. When Catalina wonders whether a learned doctor might be found in Spain, María de Salinas tells her that the Inquisition arrested most of the learned men and that the rest fled. Jews dispersed to Portugal, Italy, Turkey, and elsewhere in Europe; Muslims, she supposes, went to Africa and the East. The exchange gives religious persecution a concrete consequence: people with knowledge are no longer available where they had lived, and their skills travel with them into exile.
Catalina’s later reflection makes that consequence personal. In her judgment, the policies of Isabella of Castile and Ferdinand II of Aragon helped drive out physicians, scientists, and scholars whose learning had been condemned as sinful. She sees a contradiction between a ruler’s admiration for learning and the banishment of those who possessed it. The Inquisition is not presented as a detailed account of administrative offices or procedure; instead, the novel shows its effects through arrests, departures, and the narrowing of access to knowledge.
Catalina’s Changing Judgment
At first, Catalina defends the religious judgments she has inherited, describing the scholars’ learning as heretical. Her encounters with the consequences of that policy gradually alter her perspective. Remembering the compassion of a Moorish physician, she can no longer accept the easy division of Muslims into barbarians or enemies. She allows that a person of another faith may have reasons for his beliefs and recognizes shared human fallibility, hope, and devotion.
That change reaches beyond her view of the physician. Catalina reconsiders her parents’ authority and judges that, in driving out Jewish and Muslim communities and their learning, they acted unjustly despite their own commitment to justice. She continues to love her mother, but no longer treats her as infallible or assumes that her mother’s convictions must be identical with God’s. The Inquisition’s effects therefore appear not only in the lives of those arrested or driven away, but in the doubts that its religious program awakens in the daughter of the rulers who enforced it.
Narrative Significance
The Spanish Inquisition represents the coercive side of a political ideal that equates religious uniformity with national unity. The narrative contrasts that ideal with the promise of a society in which people of different faiths could live together, and with Catalina’s increasingly personal recognition that belief does not erase another person’s humanity. The contrast is not resolved through an institutional reform or a reversal of policy. Instead, the lasting consequence shown here is a change in Catalina’s understanding: she rejects persecution and cruelty on the basis of faith, and no longer accepts a crusade against Muslims as a self-evident duty.
